The filter screen 2 is installed inside the device. When the water passes through the device, the filter screen 2 can intercept larger solid waste, such as leaves, plastic bags, etc., and leave them inside the cleaning chamber 1, avoiding these debris from flowing into the pipe, making it difficult to clean and clogging the pipe.

[0022] The push piece 7 forms a telescopic structure with the control seat 5 through the telescopic column 6. The push piece 7 and the filter screen 2 are connected by a card slot. The push piece 7 matches the size of the filter screen 2. The control seat 5 extends the telescopic column 6 to push the push piece 7 to reach the position of the filter screen 2, clean the holes of the filter screen 2, push the blocked objects into the cleaning cavity 1, and the push piece 7 is embedded in the filter screen 2 to close the channel of the left fixed shell 3 on the left side of the cleaning cavity 1.

[0023] The anti-blocking cleaning mechanism 9 includes a second fixed connecting frame 901, a motor 902, a high-pressure nozzle 903, a rotating shaft 904, a crushing blade 905, a connecting rod 906, a fixing plate 907, a rotating plate 908, a rubber strip 909 and a sealing plate 910. The second fixed connecting frame 901 is arranged inside the right fixed shell 8, one end of the second fixed connecting frame 901 is connected to the motor 902, a high-pressure nozzle 903 is arranged on the side of the motor 902, a rotating shaft 904 is arranged on the side of the motor 902, a crushing blade 905 is arranged on one end of the rotating shaft 904, and a connecting rod 90 is arranged on the side of the motor 902. 6. A fixing piece 907 is arranged inside the right fixing shell 8, a rotating piece 908 is arranged on the side of the connecting rod 906, a rubber strip 909 is arranged on the surface of the fixing piece 907, and a sealing piece 910 is arranged on the surface of the rotating piece 908. The rotating piece 908 on one side of the right fixing shell 8 is opened, and the push piece 7 is moved to the original position. The high-pressure nozzle 903 flushes again to flush out the solid debris. The anti-blocking cleaning mechanism 9 can replace manual cleaning of the filter screen 2 in time. The cleaning operation is simple, the cleaning efficiency is improved, and the blockage of one side of the filter screen 2 inside the pipeline is avoided, so that the drainage is smooth and the travel of vehicles and pedestrians on the road will not be affected.

[0024] The second fixed connecting frame 901 and the motor 902 are welded, and the crushing blade head 905 and the rotating shaft 904 are connected by a slot. The crushing blade head 905 and the motor 902 form a rotating structure through the rotating shaft 904. Solid debris floating in the water is broken down into debris under the high-speed rotation of the crushing blade head 905.

[0025] The high-pressure nozzle 903 is connected to the motor 902 by a card slot. The high-pressure nozzle 903 is distributed at equal distances around the motor 902. Multiple groups of high-pressure nozzles 903 flush the inside of the cleaning cavity 1. By impacting the water flow, the inner wall of the pipe is cleaned and debris is removed from the pipe wall. At the same time, the high-pressure nozzle 903 stores water in the sealed cleaning cavity 1.

[0026] The fixed sheet 907 is welded to the right fixed shell 8, the rotating sheet 908 forms a rotating structure with the fixed sheet 907 through the connecting rod 906, the rubber strip 909 is connected to the fixed sheet 907 by a slot, and the sealing sheet 910 is connected to the rotating sheet 908 by a slot. The connecting rod 906 drives the two rotating sheets 908 to correspond to the notch positions respectively.

[0027] Working principle: First, the filter 2 is installed inside the device. When the water flows through the device, the filter 2 can intercept larger solid garbage, such as leaves, plastic bags, etc., and leave them inside the cleaning chamber 1 to prevent these debris from flowing into the pipe and clogging the pipe due to difficulty in cleaning. When descaling the holes of the filter 2, the control seat 5 extends the telescopic column 6 and pushes the push piece 7 to reach the position of the filter 2, cleans the holes of the filter 2, and pushes the blocked objects into the cleaning chamber 1. When there are more solids stored inside, in order to maintain normal drainage, the push piece 7 is embedded in the filter 2 to close the channel of the left fixed shell 3 on the left side of the cleaning chamber 1. The connecting rod 906 drives the two rotating pieces 908 to correspond to the notch positions respectively. During the rotation process, the rotating piece 908 drives the sealing piece 910 to fall on the fixed piece 907, and the rubber strip 909 fixes the fixed piece on the other side. The sheet 907 is connected to the rotating sheet 908, so that the entire right fixed shell 8 is isolated from the outside. Multiple groups of high-pressure nozzles 903 flush the inside of the cleaning cavity 1. By impacting the water flow, the inner wall of the pipe is cleaned and debris is removed from the pipe wall. At the same time, the high-pressure nozzle 903 stores water in the sealed cleaning cavity 1. The crushing blade 905 forms a rotating structure with the motor 902 through the rotating shaft 904. The solid debris floating in the water is decomposed into debris under the high-speed rotation of the crushing blade 905. The rotating sheet 908 on one side of the right fixed shell 8 is opened, and the push sheet 7 moves to the original position. The high-pressure nozzle 903 flushes again to flush out the solid debris and debris. The anti-blocking cleaning mechanism 9 can replace manual cleaning of the filter screen 2 in time. The cleaning operation is simple, the cleaning efficiency is improved, and the blockage of one side of the filter screen 2 inside the pipeline is avoided, so that the drainage is smooth and the travel of vehicles and pedestrians on the road will not be affected.
