Description

Technical Field

[0001] The utility model relates to the technical field of flood discharge equipment, in particular to flood discharge equipment for water conservancy projects. Background Art

[0002] Flood discharge refers to the discharge of flood water through flood discharge channels through artificial control measures to reduce the pressure on the downstream river channel and avoid flood disasters. In water conservancy projects, flood discharge is a common measure used to ensure the safe operation of water conservancy projects such as reservoirs, hydropower stations, and embankments.

[0003] At present, in the prior art, most flood discharge equipment does not have a device to slow down the water flow. Therefore, during the flood discharge process, the water pressure inside the flood discharge equipment is too high, resulting in a strong impact force of the water flow, making it easy for the water flow to wash away the land downstream, causing soil erosion. In view of this, we propose a flood discharge equipment for water conservancy projects. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides a flood discharge device for water conservancy projects, comprising a device body, a surface of which is provided with a push device, and the push device comprises:

[0006] A pushing hydraulic cylinder, one end of which is hinged to the inner wall of the device body, an output end of which is slidably connected to a pushing rod, both ends of which are fixedly connected to one end of the push rod, and the other end of the push rod is hinged to the surface of the device body.

[0007] Preferably, the surface of the push rod is hinged to the surface of the device body, the surface of the push rod is fixedly connected to one end of the steel cable, and the other end of the steel cable is fixedly connected to the upper surface of the linkage rod.

[0008] Preferably, two sides of the linkage rod are hinged to the inner wall of the speed reducer, and two ends of the speed reducer are hinged to the inner wall of the device body.

[0009] Preferably, a plurality of speed reducers are provided, and the plurality of speed reducers are divided into two groups, and the two groups of speed reducers are symmetrically arranged on both sides of the inner wall of the device body.

[0010] Preferably, the device body comprises a water baffle, the back side of the water baffle is fixedly connected to the end face of the U-shaped water channel, and an avoidance groove is provided on the inner wall of the U-shaped water channel.

[0013] The utility model provides a flood discharge device for water conservancy projects. It has the following beneficial effects:

[0014] (1) The flood discharge equipment used in the water conservancy project is equipped with a speed reducer. When the sealing cover is opened for drainage, the linkage rod is pulled by the sealing cover through a steel cable, so that the speed reducer is flipped up, thereby slowing down the water flow and preventing the high-speed water flow from impacting the downstream land and causing soil erosion.
