    Device for laying electric cable and procedure
    The objective of the present invention is a device for carrying out the operation of cable routing for the transport and distribution of electrical energy with the help of drones or UAVs (Unmanned Aerial Vehiele).
    Drone means an unmanned aerial vehicle, also by its acronym VANT, which in
    10 English is called "Unmanned Aerial Vehicle" also known by its acronym UAV or "Remotely Píloted Aírcraft" also known by its acronym its acronym in English RPA. Particularly the unmanned aerial vehicle in the present invention is vertical take-off and landing, usually called VTOl (acronym for the English expression "Vertical Take-off and Landing"). Hereinafter throughout the text of the present invention
    15 will use the acronym UAV VTOl to refer to unmanned aerial vehicle of vertical takeoff and landing, as it is an extended expression in the sector of the invention.
    In the present invention, the expression: "street free of tree-lined vegetation to facilitate the laying process" is what is commonly known as laying street. Bliss
    20 street is necessary to run the power line without obstacles from trees or vegetation.
    The airlines of transport and distribution of electrical energy are subject to a regulation that obliges them to respect safety distances with respect to the
    25 vegetation, so as to avoid the risk of causing induction fires. Safety street is understood as the protection zone of a power line to avoid service interruptions or possible fires, and in Spain it is regulated by Royal Decree 337/2014.
    The operation of a VTOL UAV is conditioned by current legislation. The last 30 reference regulations in Spain are established in Royal Decree Law 8/2014, of July 4.
    The main conditions to develop the cable routing operation are the following:
    35 -Only production and maintenance flights from the manufacturer or maintenance organizations are allowed.
    -You can only operate in areas outside crowds of buildings or cities, towns or
    inhabited places or meetings of people outdoors, in uncontrolled airspace.-The maximum flight height is limited to 120 m and line of sight.-The pilot operating the aircraft must be of legal age, have a medical certificate and
    5 accredit some knowledge.-It is necessary to identify the aircraft and the operator.-A prior authorization request is required from the Spanish Air Safety Agency
    (TO THAT).
    - The wind speed must be less than 10 km / h and without precipitation.
    10 In the current state of the art, different methodologies for laying the electric cable are known.
    The usual procedure for laying power lines is as follows:
    15 First, a rope is passed through pulleys installed in the crossings of the original support in the first electric tower. Then by different means (all-terrain vehicle, tractor, by hand, etc.) the rope is pulled until it reaches the next support and it goes up to the pulleys installed in said second support or electric tower. It is necessary to arrange
    20 of a laying street.
    Then the same procedure is carried out taking the rope to the next support. Once the rope has been passed through the entire series of supports, it is tied to a pilot cable, and by means of shot and brake machines, the pilot cable or guide wire is passed through the entire series of supports or
    25 electric towers
    Finally, the operation is repeated by hooking the pilot cable to the conductor cables and the conductor cable is pulled until they are all laid at the end of the operation.
    30 The laying street may be different from the safety street; that is to say, it may happen that in areas where the vegetation is compatible with the power line, it is necessary to open a lane for installation. This implies a series of disadvantages of the current state of the art:
    35 -Affection to vegetation, which causes a negative environmental impact
    especially accused in the case of masses of native hardwoods.
    -Need to request permission to cut vegetation to the body responsible for themanagement of these forest stands.-Delays in the construction of the line.-Overwork costs.
    The problem of the street of laying has been tried to solve in many different ways, tests have been done with crossbows, rockets, model aircraft vehicles etc., without satisfactory results. Currently the most common solution is to resort to the laying of electric cable with helicopter, for this purpose the pilot rope is attached to the helicopter, which goes
    10 going from support to support. Thus avoiding the need for a laying street as this is done by air.
    This procedure using the helicopter has a number of drawbacks:
    15-Decreases the safety of the operation as it increases the risk of serious accidents. -The emission of greenhouse gases is triggered when using a helicopter. In addition the noise of the helicopter robot causes discomfort in wildlife and people. -Increase the costs of the operation with respect to known techniques.
    The objective of this invention is to present a new device for the laying of the electric cable that provides a solution to the aforementioned drawbacks and allows by means of a drone, an easy placement of the electric cable in the supports or electrical towers without the need to perform a lane, and an automatic opening of the system
    25 holding the electric cable to the drone at its optimum during the cable routing operation.
    This device allows the use of UAV VTOL in cable routing operations, thus being able to do without direct human intervention.
    In order to solve the aforementioned problems, the present invention discloses a device for laying electric cable characterized in that it has a cable clamping system comprising a motor (preferably a servomotor) with a switch activatable by means of a signal (preferably wireless or automatic) 35 that moves a cable clamp pin from a first stop position in which
    the pin travels through an opening to a second position, in which the pin leaves said opening free allowing the release of the cable attached to the pin.
    Preferably, the pin moves in a guided manner between two parallel walls5 separated by said opening and perpendicular to the movement of said pin,each wall having an orifice where the pin is inserted.
    Preferably said fastening system between the cable and the cable routing device has a safety ring that connects the electric cable with the pin.
    Preferably said safety ring is a mechanical fuse that opens or breaks when a limit voltage is exceeded.
    Preferably, said cable has at least one flag to allow to know the distance in which the drone is located with respect to the position of an observer and to be able to discern if the cable is still linked to the drone.
    Preferably said cable has at least one tensioning weight of said cable.
    The present invention also discloses an unmanned aerial vehicle (VANT) with propulsion, take-off and vertical landing systems characterized in that it comprises the device for laying electric cable.
    In addition, the present invention also discloses the use of the aerial vehicle (VANT) for laying cable of an electric line.
    The present invention also discloses a method of laying electric cable using the device characterized in that an air vehicle operates by following the following steps:
    30-A cable is attached to the vehicle, and it takes off by pulling it through the cable holding device. -The vehicle is guided by an autonomous or manual navigation system monitored from a ground station.
    35 -When the vehicle reaches the destination coordinates, it automatically releases the cable through the movement of the pin moved by the engine.
    - Once the cable has been passed between the two electric towers, this cable serves as a guide, and thicker cables are successively hooked until the electric cable pulled with pull and brake machines is passed at the ends of the cable.
    5 An advantage of cable routing through a drone is that with operating costsvery small, the need to execute the street through felling works is avoidedlaying, necessary in forested areas so far, unless they were usedremarkably more expensive, and more risky methods, such as the helicopter.
    10 In addition, discomfort on wildlife and population due to noise and transfer of work personnel is reduced, since these discomforts are minimal in the operation for laying the power cable by drone.
    The carbon footprint is reduced, both directly (it represents a sensible saving of 15 emissions), and indirectly: by decreasing woodcutting.
    The risk of accidents is also reduced compared to other laying methodologies, especially with regard to helicopter laying, but also with regard to woodcutting.
    The invention also allows to solve technical problems to the operation in complicated places, such as laying on tension lines, railway lines, large bodies of water etc.
    25 For better understanding, some drawings of an embodiment of the advertising arrangement, object of the present invention, are attached by way of explanatory but not limitative example.
    Figure 1 shows a perspective view of a power cable laying device.
    Figure 2 shows a plan view of a power cable laying device of Figure 1.
    Figure 3 shows a general scheme of a drone equipped with the laying device 35 of the electric cable of Figures 1 and 2.

    Figures 1 and 2 show an exemplary embodiment of a cable laying device -1-which has a motor -2- and a clamping surface -7- for connection to a drone (see figure 3). Said joining surface -7-joins the device -1-to the drone -8-by means of joining elements such as nuts and bolts.
    To said device -1-the cable -6-is fastened by means of a safety ring -5-that is held together to the cable-laying device -1-by means of the pin -4-which crosses the ring -5-and the piece housed -12-shaped hook in its two holes. Said housing piece -12-has a U-shape forming the housing where the ring -5- is placed to join said device -1 by passing the pin -4-through the inside of the ring -5-.
    Said surfaces -7-join the drone -8-with the device through nuts, not shown in the figures,
    Said motor -2-moves by means of an actuator -3-the pin -4-from a first closed or closed stop position, in which the pin -4-crosses the two holes of the housing part -12-closing the part, to a second position of opening of the pin, in which the pin is located only inside a hole leaving free the housing of the housing part. Said second position, not shown in the figures, leaves the entire housing where the safety ring -5- free, releasing the safety ring -5 and in turn the cable -6-.
    In the aforementioned closing position, the pin -4-passes through the two holes of the housing part -12-And also the safety ring -5-as can be seen in figures 1 and 2. Thus fixing the ring of safety -5-in the device -1 -for the laying of electric cable.
    Said safety ring 5 has a system not shown in the figures, which allows the opening of the safety ring in cases of high tension in the cable, for example through a mechanical fuse. Thus, in the event that said cable -6-has been hooked to a tree during the operation of laying the electric cable, the safety ring -5-acts as a mechanical fuse, it is a safety system that allows breaking the junction between the cable -6- through the ring -5- and the device -1-attached to the drone -8-. Said maximum tension at which the safety ring opens -5- is configurable depending on the design of the safety ring -5-. It can be configured by design, for example, that the safety ring -5- is broken for a certain tension value, by opening and releasing the cable -6-.
    Figure 3 shows a general scheme of the cable laying operation where5 you can see the -1-cable laying device attached to the drone -8-.
    The cable -6-has a weight -10-in order to tension said cable for proper operation in the laying operation.
    10 The flags -9-along the cable -6-allow an external observer (eg system operator, external observer, etc.) to know the distance to which it is by extrapolation between the distance observed between the flags and knowing the real distance between these flags, thus allowing the drone to operate more safely.
    15 The roller -11-allows the storage of the cable -6-during the laying operation. Said roller -11-has an additional safety system not shown in the figures which allows the cable -6-to be cut in case of said cable -6-hooking with an obstacle. Additionally, the roller 11 may have a cable tension / braking system in the coil.
    The present invention discloses an electrical cable laying procedure using the cable-laying device based on drone technology that operates as follows:
    25 -Firstly, a wire with high resistance to the drone is attached, and this takes off by pulling it by means of a device for securing the wire or cable. -The flight is guided by a navigation system assisted from a computer. When it reaches the target coordinates, it automatically releases the wire by the movement of a pin moved by a motor.
    30 -Once the thread is passed between the two spans, this serves as a guide, thicker ropes are successively hooked until the pilot rope is passed. -Finally, the laying operation is normally done with shooting and brake machines at the ends.
    Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive or other details that could be evident to the technicians of the sector could later be variable. of interpreting the subject matter disclosed in the present description, claims and drawings.
