Technical Field

[0001] The utility model belongs to the technical field of water conservancy sewage interception stations, in particular to a water conservancy sewage interception station. Background Art

[0002] The hydropower sewage interception station is used to intercept floating sewage in the river upstream of the hydropower station. The sewage may include large objects such as dead wood and tree roots. If the sewage enters the flow channel of the power station, it will pose a threat to the safe operation of the hydropower station.

[0003] For example, the Chinese patent with the announcement number CN217203938U discloses a sewage interception station for water conservancy and hydropower in the flood season, including piles, two of which are fixedly connected to the middle of the inner top wall of the piles with three motors, the lower driving ends of the three motors are fixedly connected to threaded rods, the middle and lower outer peripheries of the threaded rods are threadedly connected to threaded sleeves, the ends of the threaded sleeves that are close to each other are fixedly connected to connecting plates, the upper end of the bottom plate is fixedly connected to a sewage interception mesh plate, the water inlet end of the centrifugal pump that is far away is fixedly connected to a pumping pipe, and the rear side of the connecting pipe is evenly distributed with high-pressure spray guns. In the utility model, after the sewage interception station is used, the debris remaining on the sewage interception mesh plate can be cleared in time to avoid affecting the next use, and the debris remaining on the sewage interception mesh plate can be prevented from corroding the sewage interception mesh plate, thereby extending the service life of the sewage interception station.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: when in use, the above device may be damaged and need to be replaced due to large dirt hitting the dirt screen, and the dirt screen needs to be disassembled with tools when replacing, which is not convenient. At the same time, the dirt screen cannot intercept dirt when replacing, which may cause dirt to enter the flow channel of the power station, threatening the safe operation of the hydropower station. In view of this, we propose a hydraulic dirt interception station. Utility Model Content

[0006] The purpose of the utility model is to provide a water conservancy sewage interception station to solve the problems raised in the above background technology.

[0015] The two sliding bars on both sides of the new filter screen slide in the direction away from the new filter screen under the action of the rebound force of the two springs on both sides of the new filter screen, and the two sliding bars on both sides of the new filter screen respectively enter the two limiting grooves on the front side. At this time, the positions of the sliding bars on both sides of the new filter screen will be fixed, and the position of the new filter screen will be fixed at the same time, so that the filter screen can be easily replaced without causing dirt to enter the flow channel of the power station.

[0016] In the above technical solution, further, the sides of two adjacent sliding bars that are close to each other are tightly fitted, and the sides of two adjacent sliding bars that are away from each other are tightly fitted with the corresponding stakes.
