[0025] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0026] Please combine Figures 1 to 6Now, a water supply and drainage silt removal device provided by the present invention is described.

[0027] In this embodiment, the water supply and drainage desilting device includes an outer pipe 1, an inner pipe assembly 2, a vibration assembly 3 and a rotating member 4. The outer pipe 1 is sleeved on the outer side of the inner pipe assembly 2. The outer pipe 1 and the inner pipe assembly 2 are connected through the rotating member 4. The vibration assembly 3 is arranged inside the inner pipe assembly 2 and connected to the inner wall of the outer pipe 1. The inner pipe assembly 2 includes an inner pipe 21, a filter screen 22, and a driving blade 23. The driving blade 23 is fixed on the outer wall of the inner pipe 21, and the filter screen 22 is connected to the end of the inner pipe 21. When liquid enters from the outer pipe 1, part of the liquid impacts the driving blades 23 downward from the filter screen 22, causing the inner pipe 21 to rotate, and the inner pipe 21 causes the vibration component 3 to produce periodic motion.

[0028] It can be understood that the water supply and drainage silt removal device includes an outer pipe 1, an inner pipe component 2, a vibration component 3 and a rotating part 4. The outer pipe 1 is sleeved on the outside of the inner pipe component 2. The outer pipe 1 and the inner pipe component 2 are connected by a rotating part. The vibration component 3 is arranged inside the inner pipe component 2 and connected to the inner wall of the outer pipe 1. The inner pipe component 2 includes an inner pipe 21, a filter screen 22, and a driving blade 23. The driving blade 23 is fixed on the outer wall of the inner pipe 21, and the filter screen 22 is connected to the end of the inner pipe 21; when the liquid enters from the outer pipe 1, part of the liquid impacts the driving blade 23 downward from the filter screen 22, so that the inner pipe 21 rotates, and the inner pipe 21 causes the vibration component 3 to produce periodic motion, thereby achieving the purpose of clearing silt. The device has a simple structure, omits the complex silt removal mechanism and motor components in the traditional device, reduces the manufacturing cost and maintenance difficulty, and improves the reliability and durability of the equipment.

[0029] It should be noted that after part of the liquid is filtered from the filter screen 22, it impacts the driving blade 23. The driving blade 23 rotates in a clockwise direction under the impact force of the liquid, driving the inner pipe 21 to rotate in a clockwise direction, thereby driving the vibration component 3 to produce periodic radial motion, thereby achieving the purpose of clearing the blockage.

[0030] In this embodiment, the vibration component 3 includes a vibration hammer 31, an elastic sheet 32 ​​and a driving block 33. The driving block 33 is arranged on the inner wall of the inner pipe 21. The driving block 33 abuts against one end of the elastic sheet 32. The other end of the elastic sheet 32 ​​is connected to the inner wall of the outer pipe 1. The elastic sheet 32 ​​is connected to the vibration hammer 31. When the liquid impacts the driving blade 23 to drive the inner pipe 21 to rotate, the driving block 33 drives the elastic sheet 32 ​​to swing back and forth, and the elastic sheet 32 ​​drives the vibration hammer 31 to perform periodic radial motion. The vibration component 3 uses the liquid flow to impact the driving blade 23 to drive the inner pipe 21 to rotate, and the driving block 33 drives the elastic sheet 32, so that the vibration hammer 31 performs periodic radial motion. No motor is required, which reduces energy consumption and improves the operating efficiency and reliability of the pipeline system.

[0031] In this embodiment, the driving block 33 also includes a buffer portion 331 and a protrusion 332. The buffer portion 331 is connected to the protrusion 332. The elastic sheet 32 ​​is preferentially abutted against the buffer portion 331, and preferentially passes through the buffer portion 331 and then through the protrusion 332 before being reset. When the liquid impacts the driving blade 23 to drive the inner pipe 21 to rotate, the elastic sheet 32 ​​is lifted up by the protrusion 332 after passing through the buffer portion 331, and resets after passing through the protrusion 332, thereby driving the vibration hammer 31 to perform periodic radial movement. The buffer portion 331 can enter between the elastic sheet 32 ​​and the inner wall of the inner pipe 21, and abut against the end of the elastic sheet 32, so that the elastic sheet 32 ​​moves more smoothly, reducing the impact on the pipe wall, while ensuring the stability and periodicity of the movement of the vibration hammer 31, and improving the pipeline cleaning effect.

[0032] In this embodiment, the vibration assembly 3 also includes a fixing frame 34 and a connecting frame 35. The length of the fixing frame 34 is the same as the diameter of the inner wall of the outer pipe 1. The fixing frame 34 is fixed on the inner wall of the outer pipe 1. The elastic sheet 32 ​​is connected to the inner wall of the outer pipe 1 through the fixing frame 34. One end of the elastic sheet 32 ​​is connected to the center of the fixing frame 34, and the other end is in contact with the driving block 33. When the driving block 33 is displaced under the action of external force, the fixing frame 34 and the connecting frame 35 can directly transfer the force on the elastic sheet 32 ​​to the vibration hammer 31, thereby driving the vibration hammer 31 to perform periodic radial motion. The vibration assembly 3 is connected more firmly, the force is more evenly applied, the power of the driving block 33 can be better transmitted, and the stability and reliability of the radial motion of the vibration hammer 31 are ensured.

[0033] In this embodiment, the driving blades 23 are arranged at intervals along the circumferential direction of the outer wall of the inner pipe 21. A driving blade 23 is installed at intervals of a fixed arc length on the circumference of the outer wall of the inner pipe 21, forming a uniformly distributed interval arrangement, so that the impact force of the liquid on the driving blades 23 is evenly distributed, thereby driving the inner pipe 21 to rotate smoothly and at a uniform speed.

[0034] In this embodiment, the rotating member 4 is arranged at both ends of the inner part of the outer pipe 1, and the outer wall of the inner pipe 21 is rotatably connected to the inner wall of the outer pipe 1 through the rotating member 4. Specifically, the rotating member 4 is a bearing. The rotating member 4 can reduce the friction resistance of the inner pipe 21 when rotating in the outer pipe 1, so that the inner pipe 21 can rotate more smoothly and flexibly.

[0035] In this embodiment, the outer diameter of the filter screen 22 is the same as the inner diameter of the outer pipe 1, and the inner diameter of the filter screen 22 is the same as the outer diameter of the inner pipe 21. The diameter of the cross section of the filter screen 22 gradually increases in the direction away from the inner pipe 21. This allows the filter screen 22 to fit closely to the inner pipe 21 and the outer pipe 1, effectively filtering impurities in the liquid and reducing the accumulation and blockage of the liquid at the filter screen 22.

[0036] In this embodiment, the outer pipe 1 includes a water inlet 11 and a water outlet 12. The water inlet 11 is arranged above the port of the filter screen 22, and the water outlet 12 is arranged below the port of the filter screen 22. When the liquid flows from the water inlet 11 to the water outlet 12, it impacts the driving blade 23 through the filter screen 22. The driving blade 23 drives the inner pipe 21 to drive the driving block 33 to rotate, and the elastic sheet 32 ​​drives the vibration hammer 31 to perform periodic radial motion. By utilizing the flow energy of the liquid, the dirt on the inner wall of the pipe can be effectively removed without a motor, ensuring the smooth flow of the liquid in the pipe.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
