    DESCRIPTION

    Water level regulator system of a channel.

    The present invention relates to a water level regulator system of an irrigation channel. More specifically, the invention provides a water level regulator system for an irrigation canal, whose function is to drive the water from the collection to the field or orchard where it will be applied to the crops, allowing the system to maintain a constant water level at along the canal, as well as avoiding overflows or other possible water losses, facilitating in turn an irrigation on demand appropriate to the 10 needs of the crop.

    Currently, the cultivation channels must be carefully designed so as not to cause damage to the environment and to achieve the lowest possible water expenditure. Because they are closely linked to the characteristics of the terrain, they generally follow approximately 15 contours of this level, gently descending towards lower levels, this is giving it a downward slope, so that the water flows more quickly and less liquid is spent.

    Usually along a channel, both the amount of water flowing through it 20 and the speed with which it varies depending on the terrain, which causes water to flow faster at some sections of greater slope, with the consequent risk of turbulence and overflows. On the other hand, for the simultaneous irrigation of multiple terrains, the various channels should maintain a sufficient level of water to reach all these terrains, which is not always possible, since 25 those closest to the channel's power supply have a greater flow of water than those further away.

    To partially solve these problems, it is known in the art the use of irrigation gates, either manually controlled or automated, that distribute the water 30 through the multiple channels and try to maintain a uniform water flow in all of them. These types of known gates either require the intervention of the user or constitute expensive automatic systems that involve the provision of level controls, safety controls to prevent damage to the system, basically landfills and siphons, capacity sections intended to measure the amount of water entering a certain channel, etc.

    For example, document ES 2 307 374 B1 describes a procedure for irrigation from a ditch with water distribution in several equal flows that are distributed by means of flexible pipes to the desired points, characterized by operating 40 with a single motorized gate provided with safety spillway, a homogeneous divider of the irrigation flow with the desired number of outlet pipes and an electronic irrigation control unit that controls the operation of the gate via cable, as well as a gate equipped with a servomechanism that can be automatically governed through a cable, a device that allows its release to be used manually, a spillway that ensures that uncontrolled overflows cannot occur and guides provided with housings for optional anti-freeze heating devices to prevent blockage in case of low temperatures.

    In EP 0249558 an automatic level regulating valve is described comprising a board arranged in a hole to separate an upstream ditch and a downstream ditch, one of these ditches being a controlled ditch whose level must be maintained, this board being mobile with a movement that represents a
    vertical component to more or less seal this hole in order to let a more or less important flow of water pass and thus combat eventual variations of this level, a mobile motor drawer whose movement has a vertical component related to the movement of this board, this drawer being submerged in the water over a variable part of its height, to receive a variable flotation thrust, 5 this drawer presenting a low opening to allow water to enter this drawer and occupy a low part of variable height to increase the total weight acting on this drawer and for the vertical force resulting from this thrust and this weight to move this board, this drawer also presenting a high opening to allow air to escape from a high part that remains in this drawer and / or 10 entering it, this valve further comprising a source of air depression that creates an air depression primary in relation to the atmosphere, an air circuit comprising, in turn, a depression feed branch and a pressure exhaust branch, at least one of these branches being operable, so as to allow the said high opening in communication with this source and with the atmosphere, in order to make the water penetrate in said drawer and to let it out respectively, and a level sensor sensitive to the difference between the level of said controlled ditch and a setpoint level, activated this sensor the aforementioned actuating branch to apply an effective air depression to said engine drawer, by varying this sensor at this fraction in order to servoise the level of this ditch at this setpoint level, this valve being characterized because the said source Depression is a hydraulic suction tube, this tube comprising a water inlet that flows into the aforementioned ditch upstream, a convergent, an ent rada of aspiration of air, a divergent and an exit of water and of air that ends in the mentioned ditch downstream to make appear the mentioned depression of primary air in this entrance of 25 aspiration.

    The regulatory system of the present invention allows a regulated water level to be maintained in a simple way by at least two regulating elements based on flotation, avoiding the high costs of the aforementioned systems 30, based on a compatible design and adaptable to all types of open sky channels.

    For this, the system is constituted by a portable receiver channel intended to be placed inside an irrigation channel and in which at least two 35 water level regulating elements that act by flotation are pivotally fixed.

    The invention will now be described based on an embodiment thereof and with reference to the attached figures, in which:
     40
    Fig. 1: scheme of the regulatory system according to an embodiment of the invention;

    Fig. 2: shows a water level regulating element according to fig. 1 in a top view (2a) and a bottom view (2b);
     Four. Five
    Fig. 3: shows the operation of the regulating element of fig. 2.

    As shown in Fig. 1, the regulatory system of the invention is constituted by a portable receiver channel (1) intended to be placed inside an irrigation channel (not shown) and which is fed from the water flowing through said irrigation channel. Although this portable channel (1) has an essentially trapezoidal shape in the figure, the invention is not limited in this regard, the only limitation being that the portable channel (1) is adaptable in size and shape to an irrigation channel. This portable receiver channel (1) is
    manufactures in a light material and resistant to working conditions, being waterproof.

    In the inner zone of the portable receiver channel (1), at least two water level regulating elements (2) that act by flotation are pivotally fixed. For reasons of simplicity, a single regulatory element (2) is described here in detail, this description being applicable to all regulatory elements included in the portable receiver channel (1).

    As shown in detail in Figure 2, the regulating element (2) is constituted by a gate (3) which, in its lower zone (in the figures the arrow indicates the direction of the flow of water flowing through the receiving channel (1)), includes a flotation medium (4).

    The presence of this flotation means (4) in the downstream area of the lower part of the gate (3) causes that, when the water level is sufficient to activate the flotation means 15 (4), the gate (3 ) Tilt up, closing the water flow.

    In order to allow the gate (3) to swing inside the receiving channel (1), it is attached to the bottom wall of said receiving channel (1) by means of a tilting fixing means (5), for example of hinge type. twenty

    To prevent the flow of water from passing through the sides between the side walls of the receiving channel (1) and the gate (3), the gate (3) is fixed to the side walls of the receiving channel (1) by means of a waterproof means flexible (6), for example a flexible plastic sheet, which is also fixed to the bottom wall of the receiving channel (1) 25 as well as to the lateral edges of the channel (1) by means of suitable fixing means (7), for example with bolted plates.

    Associated with the gate (3) and upstream thereof, the system includes at least one counterweight arm (8) to regulate the level of flotation of the gate (3). This counterweight arm 30 (8) is fixed to the upper area of the sides of the receiving channel (1) by a transverse support (9). The counterweight arm or arms (8) regulate how much the gate will open or close. In one embodiment, the transverse support (9) includes a groove (10) in which different weights can be coupled to regulate the tilt of the gate (3) and, thereby, the level of water flow required. 35

    In addition, the system includes a secondary gate (11) upstream of the gate (3) closing the space defined by the bottom wall of the receiving channel (1) and the gate (3). This gate (11) is normally closed, either by the pressure that the water exerts on it or by its own weight. This gate (11) can be associated by means of a cable (12) to a counterweight arm (8), causing that, when the gate (3) tilts forward, raising the counterweight arm (8), the gate opens (11), the water contained in the lower zone defined between the bottom of the receiving channel (1) and the gate itself (3) being evacuated.
     Four. Five
    The secondary gate (11) is opened, the water contained in the lower zone defined between the bottom of the receiving channel (1) and the gate itself (3) being evacuated. Similarly, the gate (11) can be opened by manually operating the cable (12).

    In use, as shown in Figure 3, the regulatory system of the invention is disposed inside an irrigation channel, including the receiving channel (1) at least two regulating elements (2) arranged in line to a predetermined distance from each other, thereby defining within the channel (1) essentially separate spaces. When water flows through the receiving channel (1) in the direction of the arrow shown in the
    figures, the gates (3) allow their passage to the different separate delimited spaces until a level determined by the flotation and the counterweight defined in each gate is reached. Then, these gates (3) swing upwards closing the passage of water in each of said spaces. When it is irrigated, the water level of the system is maintained upstream of the gate (3), so that a remaining water remains in the receiving channel (1) available for further irrigation. Thus, each space upstream of each gate can be used independently for selective irrigation. If a complete emptying of the receiving channel (1) is necessary, for example for maintenance purposes, the secondary gates (11) are opened in the manner described above. Therefore, by regulating the counterweight and flotation components described, the level of water that is maintained in the receiving channel is regulated, so that the desired constant level is achieved.

    In one embodiment of the invention, the gate (3) is made of a rigid material, for example stainless steel, fiber or other material resistant to environmental and water conditions.
