Description

Technical Field

[0001] The utility model relates to the technical field of sluices, in particular to an anti-blocking sluice for water conservancy projects. Background Art

[0002] A sluice is a low-head hydraulic structure built on rivers and channels that uses gates to control flow and adjust water levels. Closing the gates can block floods, tides or raise upstream water levels to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry and domestic water. Opening the gates can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels.

[0003] For example, the utility model disclosed provides "a water gate for water conservancy projects", and its announcement number is: CN212477625U. The patent includes a bracket and a gate located inside the bracket. The top of the bracket is rotatably connected to a reel, and two symmetrical connecting chains are arranged between the reel and the gate. Both sides of the bracket are provided with symmetrically distributed slide grooves, and the insides of the two slide grooves are rotatably connected to gears. The use of gears and moving plates puts part of the weight of the gate on the gears and the plug rods in the moving plates, and the connecting chain and the reel are not easy to deform and break.

[0004] However, this patent does not have an anti-clogging function. After the sluice gate is released, mud and sand are easily accumulated under the gate. When the gate is closed, the gate will come into contact with the mud and sand at the bottom. As the water flow flushes, the mud and sand at the bottom of the gate will be lost with the water flow, and gaps will appear at the bottom of the gate, which reduces the sealing and water-retaining performance of the gate. Therefore, the purpose of the utility model is to improve the sealing and water-retaining ability of the sluice gate by an anti-clogging mechanism. Utility Model Content

[0005] The utility model aims to provide an anti-clogging sluice for water conservancy projects, which has the advantage of good anti-clogging ability and solves the problem that the existing water conservancy projects use sluices without anti-clogging function. After the sluice is released, mud and sand are easily accumulated under the gate. When the gate is closed, the gate will contact the mud and sand at the bottom. As the water flow flushes, the mud and sand at the bottom of the gate are lost with the water flow, and a gap will appear at the bottom of the gate, which reduces the sealing and water-retaining performance of the gate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sluice gate for anti-clogging of water conservancy projects, comprising a dam body, side grooves are provided on opposite sides of the dam body, one side of the inner cavity of the side groove is fixedly connected to a limit plate, the surface of the limit plate is movably connected to a limit sleeve, a gate plate is provided on the opposite side of the limit sleeve, a mounting frame is fixedly connected to the bottom of the opposite side of the dam body, a filter frame is provided in the inner cavity of the mounting frame, mounting plates are provided on both sides of the inner cavity of the mounting frame, clamping plates are provided on both sides of the filter frame, a latch is connected through the surface of the clamping plate, one end of the latch penetrates into the inner cavity of the mounting plate, and a top of the mounting frame is provided with A first sealing ring is provided, a second sealing ring is provided at the bottom of the gate plate, an extension plate is provided at the bottom of the gate plate, the bottom of the extension plate penetrates into the inner cavity of the filter frame, a support frame is provided at the top of the dam body, a motor is provided at the top of the support frame, the output shaft of the motor is fixedly connected with the first transmission wheel, the top of the inner cavity of the support frame is movably connected with a screw, the surface of the screw is provided with a second transmission wheel, the surface of the first transmission wheel is transmission-connected to the surface of the second transmission wheel through a belt, a cross plate is fixedly connected to the top of the opposite side of the dam body, a threaded tube is provided in the inner cavity of the gate plate, and the surface of the screw is threadedly connected to the inner cavity of the threaded tube.

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

[0013] 1. The utility model enables the water gate of the water conservancy project to have the advantage of good anti-clogging ability through the coordinated use of the dam body, side grooves, limit plates, limit sleeves, gate plates, installation frames, filter frames, installation plates, card plates, latches, first sealing rings, second sealing rings, extension plates, support frames, motors, first transmission wheels, screws, second transmission wheels, cross plates and threaded pipes, thereby solving the problem that the water gates used in existing water conservancy projects do not have the anti-clogging function.

A cross plate 19 is fixedly connected to the top of the opposite side of the dam body 1, and a threaded tube 20 is provided in the inner cavity of the gate 5, and the surface of the screw 17 is threadedly connected to the inner cavity of the threaded tube 20.

[0023] A housing is disposed at the bottom of the support frame 14 , and the first transmission wheel 16 and the second transmission wheel 18 are both located in the inner cavity of the housing.

[0024] Through the above technical solution, a housing is provided to protect the first transmission wheel 16 and the second transmission wheel 18, so as to prevent them from being exposed to the outside and being damaged.

[0025] The front side of the gate plate 5 is provided with buffer strips 21 , and the number of the buffer strips 21 is ten and they cross each other.

[0026] Through the above technical solution, by providing the buffer strips 21 , the ten buffer strips 21 arranged crosswise can buffer the impact force of the water flow, thereby extending the service life of the gate plate 5 .

[0027] A limiting groove is provided on the front side of the limiting plate 3, and the inner wall of the limiting sleeve 4 is movably connected to the inner cavity of the limiting groove through a limiting block.

[0028] Through the above technical solution, by setting the limiting groove to limit the limiting sleeve 4, not only can the limiting sleeve 4 be more stable when moving, but also the moving range of the limiting sleeve 4 can be limited.

As the gate plate 5 moves upward, the second sealing ring 12 at the bottom of the gate plate 5 is separated from the first sealing ring 11 at the top of the mounting frame 6. As the gate plate 5 rises, the water flow through the dam body 1 gradually increases, and the silt at the bottom of the water flow will be blocked by the filter frame 7 and will not move to the bottom of the gate plate 5 with the water flow. Therefore, after the flood discharge is completed, the motor 15 is reopened, and the motor 15 drives the screw 17 to rotate. The rotation of the screw 17 causes the gate plate 5 to move down again, and the extension plate 13 at the bottom of the gate plate 5 can directly contact the top of the base, and there will be no silt blocking it to reduce the sealing and water-retaining performance. In daily maintenance work, the water conservancy project staff can remove the filter frame 7 for maintenance or replacement during the dry season or by diving into the water.
