Description

Technical Field

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

[0002] Gates are control facilities used to close and open discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. They are widely used in water conservancy projects such as agricultural irrigation, hydropower generation, flood control and discharge.

[0003] After searching, the Chinese patent number CN217026933U discloses that the utility model relates to the field of gate technology, specifically a flood control gate for a water conservancy project, wherein two first chutes are provided on the top of the dam body, a filter plate is provided on one side of the dam body, a liquid level sensor is provided on one side of the dam body, one side of the liquid level sensor is fixedly connected to one side of the dam body, the liquid level sensor is located on one side of the filter plate, a buffer plate is provided on one side of the dam body, and two fixed plates are fixedly connected to the top of the dam body, and the two fixed plates are symmetrically arranged. The advantage of the utility model is that the flood control gate of the water conservancy project can effectively remove debris in the water through the filter plate, and avoid the water flow carrying debris to hit the flood control gate, thereby causing damage to the flood control gate, and through the buffer plate and the buffer holes provided on the buffer plate, the water flow can effectively slow down the impact of the water flow when passing through the buffer holes on the buffer plate, thereby increasing the service life of the flood control gate.

[0004] Existing gates are generally equipped with filter plates to remove debris in the water and prevent the water flow from carrying debris and hitting the flood control gates. However, after long-term use, a lot of debris will remain on the filter plate, and the device itself lacks the necessary cleaning structure, causing this part of the debris to stay and gather on the filter plate, causing the filter plate to be blocked. Based on this, the utility model designs a water conservancy project flood control gate to solve the above problem. Utility Model Content
