Description

Technical Field

[0001] The utility model relates to the technical field of river channel water blocking devices, in particular to a river channel water blocking device. Background Art

[0002] A river channel is the route through which water flows, usually referring to a navigable waterway. There are roughly two types of existing river water-blocking devices. One is a larger water conservancy project that releases or blocks water through gates; the other is a simple water-blocking device.

[0003] Existing river water interception devices generally achieve the water interception function by raising and lowering the gate plate through a threaded rod structure. However, in this water interception method, the weight of the gate plate is entirely on the threaded rod. It is quite laborious to manually turn the threaded rod to raise the gate plate. If a motor is used to rotate the threaded rod, the energy consumption is also large, and improvement is needed. Utility Model Content

[0008] In order to maintain good sealing between the water retaining plates and prevent water leakage, as a preferred river water retaining device of the utility model, the outer walls of the plurality of the slots are all provided with rubber pads.

[0009] In order to prevent water from entering the servo motor and the controller, as a preferred river water blocking device of the utility model, the height of the frame is greater than the height of the water surface of the river.

[0010] In order to prevent the spur rack from rotating with the threaded rod, as a preferred river water interception device of the utility model, the lower end surface of the spur rack abuts against the upper end surface of the frame.

[0011] In order to facilitate the control of the equipment, as a preferred river water interception device of the present invention, the outer wall of the frame is provided with a controller, and the servo motor is electrically connected to the controller.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This river water blocking device can drive multiple water baffles to rotate synchronously through the cooperation of servo motors, threaded rods, spur racks, gears, rotating shafts and water baffles. When the water baffles are rotated to be flush with the frame, the frame is closed to block water. When the water baffles are rotated to be perpendicular to the frame, the water flow is maximum. The water flow can be adjusted by rotating the water baffles to different angles. Water is blocked by rotating the water baffles. The weight of the water baffles is all applied to the frame. Rotating the water baffles is relatively light, saving energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
