Description

Technical Field

[0001] The utility model relates to a water conservancy gate, in particular to a water conservancy gate which is easy to maintain and belongs to the technical field of gates. Background Art

[0002] The gate is a control facility used to close and open the water discharge (release) channel. It is an important part of hydraulic structures and can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. When selecting the gate type, it is necessary to determine it through technical and economic comparison based on the working nature of the gate, setting location, operating conditions, gate span, opening and closing force, and project cost, combined with the characteristics of the gate, and referring to the existing operating practice experience.

[0003] After extensive searching, it was found that: China Utility Model Patent Column: Publication No. 202320010560.X A hydraulic gate that is easy to maintain belongs to the technical field of hydraulic gates. It includes a support frame, a driving mechanism, a gate channel, and a gate body. The gate body is tightly fitted and slidable with the inner wall of the flood discharge channel in the middle of the gate channel. The support frame includes two side plates, a middle cross bar connected to the top of the two side plates, and support plates respectively connected to the bottom of the two side plates. The two support plates are respectively detachably connected to the top of both sides of the gate channel. The driving mechanism passes through the middle cross bar of the support frame and is detachably connected to the top of the gate body.

[0004] Although the device is convenient for disassembling and assembling the gate and the threaded rod, the gate is not fixed during the disassembly and assembly process, and the gate is still supported by the threaded rod. Once the gate is disconnected from the threaded rod, the gate will topple or fall into the flood discharge channel. Therefore, it is necessary to use equipment structures such as cranes or steel pipes to lift or support the gate. However, the crane will be blocked by supporting structures such as support frames or opening and closing chambers, making it impossible for the crane to lift the gate. Steel pipe support is very time-consuming and labor-intensive, and it is not easy to move the gate. Therefore, the fixing and transportation of the gate becomes very troublesome, affecting the maintenance and replacement of the gate. Utility Model Content
