[0028] The filtering assembly 5 includes an annular cylinder 51 and a conical filter cylinder 52 fixed on one side of the annular cylinder 51. The annular cylinder 51 is slidably connected to the inner wall of the cylinder body 21. The crushing assembly 3 includes a spindle column 31 rotatably mounted on the inner side of the annular cylinder 51.

[0029] Furthermore, by providing the annular cylinder 51 , it can be ensured that the conical filter cylinder 52 and the cylinder body 21 always maintain a coaxial state.

[0030] The driving assembly 4 includes a hollow frame 41 fixedly mounted on the inner wall of the cylinder 21. The hollow frame 41 is arranged on the side of the conical filter cartridge 52 away from the annular cylinder 51. A rotating shaft 42 is rotatably mounted on the hollow frame 41. An impeller 43 is fixedly mounted on the end of the rotating shaft 42 away from the grinding assembly 3. The rotating shaft 42 movably penetrates the conical filter cartridge 52 and is fixedly connected to the grinding surface 33.

[0031] A connecting plate 55 is fixedly installed on the side of the conical filter cartridge 52 away from the annular cylinder 51, and a guide rod 56 is fixedly installed on the side of the connecting plate 55 away from the conical filter cartridge 52.

The cam ring 54 is located between the two rollers 58 and is rollingly connected to the two cam rings 54.

[0032] The grinding surface 33 is provided with a plurality of grooves 34 distributed in a circular array, the shuttle-shaped column 31 is provided with a cavity 36, an annular plate 37 is slidably installed in the cavity 36, two circular tubes 38 are slidably installed through the groove 34, one end of the two circular tubes 38 close to the annular plate 37 penetrates the annular plate 37 and is fixedly connected to the annular plate 37, one end of the two circular tubes 38 away from the annular plate 37 is fixedly installed with the same arc-shaped hollow plate 35, and the side of the plurality of arc-shaped hollow plates 35 away from the grinding surface 33 is slidably connected to the inner wall of the conical filter cartridge 52, and a tension spring 310 is slidably sleeved on the circular tube 38, and the two ends of the tension spring 310 are respectively fixedly connected to the annular plate 37 and the inner wall of the cavity 36.

[0033] One end of the circular tube 38 away from the annular plate 37 is connected to the interior of the arc-shaped hollow plate 35. A plurality of water spray holes 351 distributed linearly are provided on the side of the arc-shaped hollow plate 35 away from the grinding surface 33. A pumping mechanism 39 is provided at one end of the circular tube 38 away from the arc-shaped hollow plate 35. The arc-shaped hollow plate 35 is connected to the pumping mechanism 39 through the circular tube 38.

[0034] The pumping mechanism 39 includes a cylinder 392 fixedly installed on the inner wall of the cavity 36 away from the arc-shaped hollow plate 35, a piston ring plate 393 is slidably installed in the cylinder 392, an outlet pipe 394 is fixedly installed on the inner side of the piston ring plate 393, one end of the outlet pipe 394 away from the piston ring plate 393 is fixedly connected to the circular tube 38 and is coaxially arranged with the circular tube 38, a water inlet pipe 391 is fixedly installed through the cylinder 392, and a one-way valve 2 396 and a one-way valve 1 395 are fixedly installed on the water inlet pipe 391 and the water outlet pipe 394 respectively.

[0035] A second channel 421 is defined on the rotating shaft 42 , a first channel 311 is defined on the shuttle-shaped column 31 , and the second channel 421 and the cavity 36 are communicated with each other through the first channel 311 .

[0036] Furthermore, by connecting the second channel 421 and the first channel 311 , the inner wall of the cavity 36 can be always filled with water. In order to prevent sand and gravel in the water flow from entering the second channel 421 , a filter net can be provided in the second channel 421 .

[0037] When the water outlet pipe 394 pulls the piston ring plate 393 away from the water inlet pipe 391, the water inside the cavity 36 will enter the cylinder 392 through the one-way valve 396. When the water outlet pipe 394 pushes the piston ring plate 393 close to the water inlet pipe 391, the water in the cylinder 392 cannot be discharged through the one-way valve 396, and can only be squeezed into the water outlet pipe 394 through the one-way valve 395.

[0038] In this embodiment: when in use, water flows into the cylinder 21 from the water inlet 22, flows into the water inlet end 11 through the water outlet 23, passes through the smart Internet of Things water meter body 1, and is discharged through the water outlet end 12. During the process of water flowing through the cylinder 21, the conical filter cartridge 52 filters the large particles of sand and gravel in the water, and the filtered large particles of sand and gravel will accumulate in the conical filter cartridge 52.

[0039] When water flows from the cylinder 21 to the water outlet 23, it will drive the impeller 43 to rotate, and the impeller 43 will drive the rotating shaft 42 to rotate, and the rotating shaft 42 will drive the shuttle column 31 to rotate. During the rotation of the rotating shaft 42, the cam ring 54 will be driven to rotate through the sleeve 53. During the rotation of the cam ring 54, the two rollers 58 will be driven to reciprocate along the axis of the rotating shaft 42. The two rollers 58 will then drive the guide rod 56 to reciprocate along the axis of their own axes through the two columns 57. The guide rod 56 will then drive the conical filter cartridge 52 to reciprocate along the axis of its own axes through the connecting plate 55. When the conical filter cartridge 52 moves toward the shuttle column 31, the inner wall of the conical filter cartridge 52 cooperates with the grinding surface 33 to crush the large particles of sand and gravel accumulated on the inner side of the conical filter cartridge 52, and the crushed small particles of sand and gravel will directly pass through the conical filter cartridge 52 and be discharged.

[0040] As mentioned above, in the process of the conical filter cartridge 52 moving toward the shuttle column 31, the conical filter cartridge 52 will push the arc-shaped hollow plate 35 to move toward the groove 34, and the arc-shaped hollow plate 35 will push the two circular tubes 38 to push the outlet pipe 394 in the corresponding pumping mechanism 39, and the outlet pipe 394 will push the piston ring plate 393 deep into the cylinder 392. At this time, the water accumulated in the cylinder 392 will pass through the one-way valve 395 and flow through the outlet pipe 394 into the circular tube 38 through extrusion. After flowing through the circular tube 38, the water flows into the arc-shaped hollow plate 35 and is sprayed out through multiple water spray holes 351. The high-pressure water flow sprayed from the multiple water spray holes 351 will flush the holes on the conical filter cartridge 52, thereby pushing out the sand and gravel blocked in the holes of the conical filter cartridge 52, and finally completing the dredging of the blocked holes of the conical filter cartridge 52.

[0041] Afterwards, when the conical filter cartridge 52 moves away from the shuttle column 31, the stretched tension spring 310 on the circular tube 38 is reset to pull the annular plate 37 toward the conical filter cartridge 52, and the column 57 then uses multiple circular tubes 38 to pull each arc-shaped hollow plate 35 from the top of the corresponding groove 34, so that no matter when the conical filter cartridge 52 approaches or moves away from the shuttle column 31, the multiple arc-shaped hollow plates 35 can always be kept in contact with the inner wall of the conical filter cartridge 52. During the rotation of the shuttle column 31, the inner wall of the conical filter cartridge 52 can be continuously scraped by the multiple arc-shaped hollow plates 35, thereby prompting fine sand and gravel to pass through the holes on the conical filter cartridge 52.

[0042] In addition, when the arc hollow plate 35 is moved out of the corresponding groove 34, the water outlet pipe 394 will pull the piston ring plate 393 away from the water inlet pipe 391. At this time, the external water will enter the water inlet pipe 391 and flow through the one-way valve 2 396 into the cylinder 392.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
