[0027] The scraper 33 is located on the inner wall of the filter 35, the moving rod 34 is located on the inner wall of the filter 35, and the spring 1 32 is located on the top of the filter 35, located on the inner wall, so that the inner wall of the filter 35 can be directly scraped to remove dirt.

[0028] A slot 36 is provided on the side of the diverter pipe 31, and a limiting block 37 is slidably connected to the inner wall of the slot 36. A pressure rod 38 is fixedly connected to the side of the limiting block 37. A hydraulic chamber 39 is fixedly penetrated at one end of the pressure rod 38 away from the limiting block 37, and an squeezing rod 310 is penetrated at one end of the hydraulic chamber 39 away from the pressure rod 38. Such a design can limit the amount of water entering the diverter pipe 31.

[0029] One end of the squeezing rod 310 away from the hydraulic chamber 39 is fixedly connected to a pressure plate 312, and the side of the pressure plate 312 is fixedly connected to a spring 2 311. The side of the spring 2 311 away from the pressure plate 312 is fixedly connected to the side of the hydraulic chamber 39. The design of the spring 2 311 is conducive to the reset of the pressure rod 38 when it is not squeezed.

[0030] A support plate 314 is fixedly connected to the side of the hydraulic cabin 39, and a sliding rod 315 is slidably connected to the side of the support plate 314. The end of the sliding rod 315 away from the support plate 314 is fixedly connected to a limiting rod 316. The design of the limiting rod 316 can limit the position of the pressure plate 312, so that the squeezing rod 310 can always squeeze the piston inside the hydraulic cabin 39.

[0031] A rectangular groove 313 is formed on one side of the pressure rod 38 close to the limiting rod 316 . The rectangular groove 313 is located on the displacement track of the limiting rod 316 . Such a design is conducive to clamping the limiting rod 316 into the rectangular groove 313 .

The design of the sieve plate 4 is conducive to preventing large particles of impurities from entering the water pipe and preventing the water pipe from being blocked.

[0033] A specific application of this embodiment is as follows: the pipeline 1 is arranged on the ground, and the water flows into the interior of the pipeline 1 through the sieve plate 4. Part of the water flows into the interior of the diverter pipe 31, and the impact force of the water flow will wash the spring 1 32. The spring 1 32 will sink and bounce downward under the impact of the water flow, and will move up and down, which will drive the scraper 33 and the moving rod 34 to move up and down. The filter screen 35 is located on the movement trajectory of the scraper 33 and the moving rod 34. The up and down movement will scrape the inner wall of the filter screen 35, and the dirt on the filter screen 35 will be effectively cleaned without manual intervention, realizing the automatic cleaning function. When the water volume of the diverter pipe 31 is controlled, the squeezing rod 310 runs through the interior of the hydraulic cabin 39. The squeezing rod 310 and the pressure rod 38 are manually squeezed, and the squeezing rod 310 will drive the internal piston of the hydraulic cabin 39 to move, and the internal piston pushes the internal liquid to move. The pressure rod 38 will be pushed out, and the pressure rod 38 is connected to the limit block 37. When the pressure rod 38 is pushed out, it will be stuck on the notch 36 inside the shunt pipe 31, so that when water flows in, the water in the shunt pipe 31 cannot enter and cannot impact the spring 1 32. At this time, the squeezing rod 310 and the pressure rod 38 are in a squeezed state. At this time, the limit rod 316 is stuck in the rectangular groove 313 on the side of the pressure rod 38, which will fix the squeezing rod 310 and the pressure rod 38 in a squeezed state. The limit block 37 will be stuck on the slot 36 of the shunt pipe 31. When there is no need to control the water flow, the limit rod 316 is manually removed from the inside of the rectangular slot 313. The squeezing rod 310 will be reset through the clamping of the spring 2 311, and the pressure rod 38 will no longer be pushed. The pressure rod 38 will drive the limit block 37 to move out of the slot 36 and no longer restrict the shunt pipe 31. The filter screen 35 can be cleaned regularly to prevent dirt accumulation from clogging the pipe 1.
