    专利说明:

    the water volume of the sluice chamber to fill the second emptied sluice chamber to half lift height, and the remaining water volume to the lifting sluice chamber can be pumped from the decreasing sluice chamber volume. In this way, you get a hydrodynamically effective plant that allows a level crossing between road and canal without the need to build a high bridge. The energy consumption needed for the pumping work can be obtained from different energy sources, or different forms of water accumulators can be used with or without hydroforaction.
    The invention will be described in the following in connection with a pair of shown exemplary embodiments, where Fig. 1 shows a side view in section of a planar crossing according to the invention in a first starting position for a surface fabric in a left lock chamber, Fig. 2 is a view according to fi g . 1 in an intermediate position, ie where half the locking is carried out, Fig. 3 is a view according to fi g. l in a bottom position, ie when the entire sludge has been carried out and where fl surface fabric can pass under the road at the lowest level, Fig. 4 is a view according to fi g. 1 in a position when the road has been passed, ie a position where unlocking is to be started in a right lock chamber.
    The level crossing between canal / watercourse and road / level road according to fi g. l has a first lock 2 with lock port l and which is maximally filled. A boat is shown at B and an intersecting carriageway at C. On the other side of the carriageway there is a second lock 4 which is completely emptied, ie. the water level there is at the same level as at a channel part 3 connecting the locks. Since the level in the channel A and the open lock 2 are equal, it is allowed that boats can pass in and out. Sufficiently wide locks and / or a sufficiently intermediate channel section allow boats to meet during the locking process. The volume of water present in the intermediate channel part 3 is in principle constant and changes only in a dependent change in the displacement of the boats accommodated in the channel part. The length of the intermediate channel part corresponds in principle to the width of the road.
    It should be noted that here only one lock chamber has been shown at each end of the intermediate channel part 3. However, there is nothing to prevent two or fl your lock chambers from being used at one or both ends of the channel part 3.
    I fi g. 2 thus shows the intermediate position where the lock chambers are emptied resp. filled, which can be done very efficiently until an equilibrium position is reached. In order for the volume fate to be reasonable with regard to turbulence and friction losses, there may be reasons to restrict a free fate at the largest height differences between the water levels in the two lock chambers, while the closer equilibrium position may require an active pumping action to minimize lock times. After the equilibrium position in fi g. 2, an active pumping action is required in order for the second initial position to be reached and for the lock gate to the intermediate channel part to be able to be opened, resp. the lock gate in the second lock chamber must be able to open to the channel part D. This position is shown in fi g. 3.
    I fi g. 4 shows the same lock position as in fi g. l, but now with the boat B in a position to be raised to the level of the channel part D. One or your boats could be found during locking procedures at the same time. Here, however, it has been chosen to only show one boat during locking.
    The present invention can very well be applied together with the techniques specified in Swedish patent applications No. 0900677-6 and No. 090073 6-0. It is thus possible to choose a level crossing which both has a lock procedure for lowering the boats to a lower level when crossing under the road / level road at the same time as an aqueduct part is used to lift boats over the road / railway. This combination solution can find applications in context when the type of boat traffic is allowed so and then perhaps a smaller number of high-masted smaller sailboats should be given the opportunity to pass.
    The invention is not limited to the exemplary embodiment shown above, but the invention can be modified, adapted and given other embodiments on the basis of the following stated claims. Thus, when there is a fl destructive watercourse and / or when the groundwater level is below the level for the intermediate channel part 3, in at least one sluice direction, water can be discharged from the sluice chamber 4 to the surroundings and water for filling in the sluice chamber 2 is taken from the channel A.

    Claims (4)
    [1]
    Device at level crossing between water channel / watercourse and road / road, characterized by lockable and openable lock chambers (2, 4) directly connected to the water channel (A, D) on both sides of the road (C), into and out of which chambers water can be alternately filled resp. emptied via a duct arrangement (E) between the lock hinges to lower resp. lifting fl surface fabric (B) in the lock chambers, and of a lower located water-filled channel part (3) between the two lock chambers, and which is limited in its length, and also provided with lock ports and into which channel part fl the surface fabric (B) can lock in for passage under the road / rail (C).
    [2]
    Device according to claim 1, characterized in that the channel arrangement (E) has pumping means (7) which pump water, from the chamber which is emptied to the one which is found.
    [3]
    Device according to Claim 1 or 2, characterized in that the valve device (6) in the duct arrangement (E) blocks water flow when a pump device (7) is inactive.
    [4]
    Method for locking fl surface fabric in connection with the passage of a wave / railway in a device of the type specified in any of the preceding claims, characterized in that the fl surface fabric (B) is passed through an open lock port 1 into a first lock chamber (2) which is in hydraulic connection with a second lock chamber (4) via a channel arrangement (E), that the lock port (1) is closed, whereby a leveling of the water levels in the two lock chambers takes place by a valve device in the channel arrangement (E) opening, after which equilibrium is reached, the water is pumped from the first sluice chamber (2) over to the second sluice chamber (4) until the water level of the first chamber (2) reaches the same low level as the water in an intermediate channel part (3) and the water in the second sluice chamber (4). ) reached the level of the duct part (D), whereupon the pumping ceases and a lock port into said intermediate duct part (3) is opened so that the surface fabric (B) can pass into this part, whereupon said lock port is just closed and the valve device (6) in channel the arrangement (E) opens, whereupon a leveling of the water levels takes place again, whereupon a back-pumping of water takes place to the first lock chamber (2) until the level in the second lock chamber (4) reaches the water level of the intermediate channel 3) and the water level of the first lock chamber (2) reaches the water level of the channel part (A), whereupon the process is repeated, ie fl the surface fabric (B) in the second lock chamber (4) is raised to the level of the channel part (D) to be released from there into this part.
