DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterway partitioning device for opening and closing a waterway for agricultural water or the like.

[0002]

2. Description of the Related Art Conventionally, gate type gates which open and close by vertically raising and lowering a partition plate have been widely used. However, this type of gate is mounted at a high position so as not to hit the partition plate in the highest position. And the switchgear is placed on top of it.
The height of the entire device is increased. For this reason, a bridge or the like may not be able to be installed because it is in the way, and the view may be obstructed to obstruct traffic, or the surrounding scenery may be impaired. Further, since the operator operates the switchgear at a high place, the danger is high.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the height of a waterway partitioning device.

[0004]

A guide rail is erected on both sides of a water channel. The upper part of the guide rail is curved in a direction along the waterway. A partition plate is fitted between these guide rails so as to be vertically movable. The partition plate is configured to be flexible like a shutter door so that it can be moved up and down along the curved guard rail. A switch is supported on the water channel, and the switch drives a rod (rack or screw bar) up and down. The lower end of this rod is fixed to the lower part of the partition plate.

[0005] When opening a water channel, the switch is used to raise the rod. Then, the lower end of the partition plate is lifted by the rod,
The partition rises along the guide rail. Since the upper part of the guide rail is curved, the partition plate rises so as to avoid the switch. When closing the waterway, lower the rod with the switch. Then, the lower part of the partition plate is pushed down by the rod, and the partition plate descends along the guide rail.

In the case of the conventional apparatus, since the partition plate rises straight up, the switch must be provided at a sufficiently high position so as not to hit the rising partition plate. However, according to the present invention, since the partition plate rises while bending so as to avoid the switch, the switch can be installed at a low position. For this reason, the frame on which the switchgear is mounted can be reduced, and the manufacturing cost can be reduced. In addition, the work position of the person operating the switch is lowered, and the safety of the work is increased. Further, since the height of the entire apparatus is reduced, the surrounding scene is hardly damaged.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, guide rails 3 each having a U-shaped cross section are installed on both sides of a water channel 1. As shown in FIG. The guide rail 3 stands vertically about 70% below,
The upper 30% is gently curved toward the downstream side.

A partition plate 5 for damping the flow is inserted between the left and right guide rails 3 so as to be vertically movable. Partition plate 5
Are flexibly formed so that the shape can be changed according to the curved shape of the guide rail 3. In this example, as shown in FIG. 3, members 6 that are long in the horizontal direction are stacked in several stages, and these members are connected by a metal band 7. The partition plate 5 can be curved. Instead of the band 7, the members may be connected with each other by a link. The mating surface is formed in a hook shape so that the members 6 come into close contact with each other when the partition plate 5 is flat.

A gantry 9 that straddles a water channel is provided immediately above the partition plate 5 in a lowered state, and a switch 11 is installed thereon. The gantry 9 is provided at a position as low as possible so as not to hit the guide rail 3. The switch 11 is a worm rack type. When the drive handle 13 is turned, the rod 15 which is a pin rack moves up and down. The switchgear 11 is an interlocking type, and the master unit 13a and the slave unit 13
b are connected by a connecting shaft 17, and the respective rods 15 of the master unit and the slave unit move up and down in synchronization. The lower ends of the left and right rods 15 are fixed to the lower part of the partition plate 5 (FIG. 2).

In FIGS. 1 and 2, the partition plate 5 descends to block the water channel 1. When opening the water channel from this state, the handle 13 of the switch 11 is turned to raise the rod 15. In this case, the partition plate 5 is lifted via the rod 15, and the partition plate 5 rises along the guide rail 3. The partition plate 5 rises vertically at first, but when it reaches the curved portion of the guide rail 3, it rises while bending along the guide rail. The partition plate 5 with the water channel 1 opened in this way is shown by a chain line in FIG. As can be seen, the partition plate 13 is dressed to avoid the gantry and the switchgear.

When the partition plate 5 is tightened, the handle 13 is turned in the opposite direction to lower the rod 15. Then, the lower part of the partition plate 5 is pushed down and descends along the guide rail 3. Thus, as shown by the solid lines in FIGS. 1 and 2, the waterway is dammed.
