Description

Technical Field

[0001] The utility model relates to the technical field of pollution interception in hydropower stations, and in particular to a pollution interception device in a hydropower station. Background Art

[0002] A hydropower station is composed of a hydraulic system, a mechanical system, and an electric energy generating device. It is a key water conservancy project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires that the utilization of water energy in the hydropower station be uninterrupted. One of the main problems in the construction of a hydropower station is the blockage of the drainage system caused by silt accumulation. The cleaning efficiency is inevitably low through manual cleaning, and when the water level is deep, it is difficult for the staff to clean the sludge at the bottom. There will inevitably be certain risks in the cleaning process, which requires the use of a sewage interception device in a hydropower station.

[0003] Patent document CN213014203U discloses a pollution intercepting device for a hydropower station, "including a fixed column, an inner side wall of the fixed column is fixedly connected to a pollution intercepting plate, the bottom of the surface of the pollution intercepting plate is provided with grid holes, the top of the pollution intercepting plate is fixedly connected to a motor box, the left and right sides of the surface of the pollution intercepting plate are provided with slide grooves, a slider is provided inside the slide groove, and a movable mesh plate is fixedly connected to one side of the slider. This pollution intercepting device for a hydropower station, through the arrangement of a motor, a rotating rod, a threaded rod and a movable mesh plate, enables the motor to be turned on after the garbage intercepted by the pollution intercepting plate reaches a certain amount, and the output end of the motor drives the rotating rod to rotate, and the threaded rod expands and contracts around the thread arranged inside the rotating rod, thereby driving the movable mesh plate to lift the garbage in the water to the water surface, thereby avoiding clogging of the grid holes of the pollution intercepting plate."

[0004] The above-mentioned equipment drives the rotating rod to rotate through the output end of the motor, and the threaded rod expands and contracts around the thread set inside the rotating rod, thereby driving the movable mesh plate to rise, thereby lifting the garbage in the water to the water surface to avoid the grid holes on the surface of the trash retaining plate being blocked by garbage. After the sludge accumulates for a period of time, the moisture on its surface is evaporated, which causes the sludge to clump. When the equipment is cleaning garbage and sludge, it is difficult to clean the agglomerated sludge on the surface of the trash retaining plate, which causes the agglomerated sludge to block the trash retaining plate, making it difficult for water to pass through the inner wall of the trash retaining plate, thereby affecting the water level downstream. This requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that a sewage interception device for a hydropower station in the prior art is difficult to clean the agglomerated sludge, thereby providing a sewage interception device for a hydropower station.
