[0042] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] like Figures 1 to 3 As shown, the technical solution of the present invention is: a device for preventing mud, sand and floating in water through a water supply pipeline, comprising a pipe body 1 equipped with a filter screen, a first layer of filtration through the filter screen to prevent large particles of impurities from being blocked outside the pipe body 1, an outlet pipe 4 connected to the pipe body 1 through a curved pipe 3, and a self-cleaning filter component 2 for filtering water flow is provided inside the pipe body 1.

[0044] like Figure 4 and Figure 6 As shown, the self-cleaning filter assembly 2 includes a coarse filter tube 201 arranged in the middle of the tube body 1, and the coarse filter tube 201 is used to filter the impurities in the water flow entering the tube body 1 for a second time. The filtered water enters the coarse filter tube 201, and passes through a plurality of fine filter plates 202 connected to the coarse filter tube 201. The fine filter plates 202 perform a third barrier filtration on the water in the coarse filter tube 201. After the filtration is completed, the water flows out from the outlet pipe 4 through the curved tube 3, and several resistance pieces 203 connected to the outer arc surface of the coarse filter tube 201 are used to strengthen the contact surface between the coarse filter tube 201 and the water flow, thereby increasing the resistance of the coarse filter tube 201 to the water flow. A spring telescopic rod 204 is provided on the coarse filter tube 201, and the coarse filter tube 201 is rebounded to its original position by the spring telescopic rod 204. Several push rods 205 are fixedly connected to the inside of the tube body 1. When the angle of some resistance members 203 is affected by the push-up action of multiple push rods 205, the self-cleaning filter assembly 2 also includes a connecting pipe 206 connected to the rear end face of the coarse filter tube 201, and the water flow is introduced into the curved tube 3 through the connecting pipe 206. The connecting pipe 206 penetrates the rear end face of the tube body 1, and multiple fine filter plates 202 are fixedly connected to the front end of the coarse filter tube 201 and the rear end thereof. The push rod 205 is fixedly connected to the lower side of the rear end inside the tube body 1.

[0045] like Figure 5As shown, the resistance member 203 includes several fixed resistance members 2031 all connected to the upper arc surface of the coarse filter tube 201, and several swinging resistance members 2032 all connected to the lower arc surface of the coarse filter tube 201. The fixed resistance member 2031 includes a first clamping block 20311 fixedly connected to the coarse filter tube 201, and the first clamping block 20311 is used to facilitate the fixation of the fixed fin 20312. The fixed fin 20312 is set to be wide at the top and narrow at the bottom. The fixed fin 20312 is used to strengthen the resistance of the coarse filter tube 201 to the water flow. The narrow end of the fixed fin 20312 is fixedly connected between the first clamping block 20311.

[0046] like Figure 7 and Figure 8 As shown, the swinging resistance member 2032 includes a second clamping block 20321 fixedly connected to the coarse filter tube 201, a swinging fin 20322 configured to be wide at the bottom and narrow at the top, the narrow end of the swinging fin 20322 is rotatably connected between the second clamping block 20321, and several push rods 205 are all located on the rear side of the swinging fin 20322, the two limit blocks 1 20323 are fixedly connected to the upper side of the inner walls on both sides of the second clamping block 20321, the limit block 1 20323 is located on the front side of the swinging fin 20322, the two limit blocks 2 20324 are fixedly connected to the lower side of the inner walls on both sides of the second clamping block 20321, the limit block 20324 is located on the rear side of the swinging fin 20322, and the angle of the swinging fin 20322 is limited by the limit block 1 20323 and the limit block 2 20324 to prevent the swinging fin 20322 from flipping too large.

[0047] The second clamping block 20321 has the same function as the first clamping block 20311 , and changes the angle of the swing fin 20322 through the top rod 205 , thereby changing the resistance of the coarse filter tube 201 to the water flow.

[0048] like Figure 9 As shown, the spring telescopic rod 204 includes: the rear end of the empty tube 2041 is fixedly connected to the rear end inside the tube body 1, the sliding tube 2042 is slidably connected in the empty tube 2041, and the spring 2043 is fixedly connected to the rear end of the sliding tube 2042. The spring 2043 is located in the empty tube 2041. The empty tube 2041 provides space for the sliding of the sliding tube 2042, and the sliding tube 2042 is rebounded to its original position by the spring 2043.

[0049] like Figure 3 and Figure 4As shown, the curved tube 3 is fixedly connected to the rear end of the tube body 1, and an annular groove 301 is opened on the inner wall of the end of the curved tube 3 away from the tube body 1. The annular groove 301 facilitates the connection of the water outlet pipe 4 with the curved tube 3 through the sliding block 401. The outer arc surface of one end of the water outlet pipe 4 is fixedly connected with the sliding block 401. The sliding block 401 is slidably connected to the annular groove 301. The water outlet pipe 4 is connected to the sliding block 401. One end is fixedly connected to the sealing ring 402. The water outlet pipe 4 is slidably connected to the annular groove 30 through the sliding block 401. 1 is convenient for connection with other equipment, and the sealing ring 402 shell prevents water leakage at the connection between the curved pipe 3 and the outlet pipe 4. The end face pipeline below the pipe body 1 is connected to a sewage box 101, and the interior of the sewage box 101 is set as an inclined surface. The rear side pipeline of the sewage box 101 is connected to a sewage pipe 102. The sewage box 101 is used to temporarily store impurities, and the impurities in the sewage box 101 are discharged through the sewage pipe 102. A valve is installed in the sewage pipe 102 to control the opening and closing state of the sewage pipe 102.

[0050] In specific use, the end of the outlet pipe 4 away from the curved pipe 3 is connected to the sewage pipe 102 with other equipment. When water is extracted, the water flows into the pipe body 1 from one end of the filter screen of the pipe body 1. When the water flows into the pipe body 1, the filter screen performs the first layer of filtration to filter out large particles of impurities. The water flow continuously impacts the pipe body 1, and some impurities are filtered by the coarse filter tube 201 and the fine filter plate 202. When the water flow impacts the pipe body 1, the water flow continuously impacts the fixed fin 20312 and the swinging fin 20322 to continuously push the coarse filter tube 201 backward. When the swinging fin 20322 contacts the top rod 205, the angle of the swinging fin 20322 changes, and the direct contact of the swinging fin 20322 with the water flow is reduced, thereby making the coarse filter The resistance of the tube 201 to the water flow is reduced, and the spring telescopic rod 204 drives the sliding tube 2042 and the coarse filter tube 201 to rebound through the spring 2043. At the same time, the swing fin 20322 falls off the top rod 205, restoring the original contact surface. The water flow drives the coarse filter tube 201 to move again through the swing fin 20322. The above movement is repeated to make the coarse filter tube 201 continue to screen, and the impurities attached to the coarse filter tube 201 and the fine filter plate 202 are screened out to prevent excessive impurities from blocking the coarse filter tube 201 and affecting the water flow rate. The cleaned water is discharged through the curved tube 3 and the outlet pipe 4. The impurities are larger in mass and fall into the sediment box 101 under the influence of gravity. The filtered impurities are then discharged through the sewage pipe 102 through the control valve.

[0051] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
