Description

Technical Field

[0001] This utility model relates to the field of water filter pipe technology, and in particular to an anti-tangle and anti-backflow water filter pipe. Background Technology

[0002] A filter pipe is a structure that can be used in pumping wells. By installing the filter pipe in the aquifer below the water surface, it can filter impurities in the water, thereby improving the purity of the pumped water. There are different types of filter pipes, such as cage filter pipes, mesh filter pipes, and gravel filter pipes. Filter pipes play an important role in agriculture, providing convenience for agricultural irrigation.

[0003] Existing water filter pipes can only filter the water flow and cannot automatically prevent backflow of the extracted liquid. If the extraction process is suddenly stopped, the newly extracted liquid can easily flow back into the container through the extraction equipment and the filter pipe. This can easily cause the unextracted liquid in the container to be mixed or contaminated, which is not conducive to protecting the liquid. Using valves to prevent backflow requires the installation of related control devices, which is not cost-effective. At the same time, the water flow impact cannot be used to prevent weeds from entangled on the outside of the filter pipe, which can easily lead to clogging of the filter pipe and does not improve the functionality of the filter pipe during use. Utility Model Content

[0004] In existing patents, water filter pipes only filter the water flow and cannot automatically prevent backflow of the extracted liquid. If extraction stops suddenly during the extraction process, the extracted liquid can easily flow back into the container through the extraction equipment and filter pipe, potentially mixing or contaminating the unextracted liquid in the container. This is detrimental to liquid protection. Using valves for backflow prevention requires related control devices, which is cost-effective. Furthermore, the water flow cannot be used to prevent weeds from tangling around the filter pipe, leading to blockages and hindering improved functionality. Therefore, this utility model provides an anti-tangling and anti-backflow water filter pipe.

[0005] The technical solution adopted by this utility model is: an anti-winding and anti-backflow water filter pipe, comprising:

[0006] The pipe body has multiple circumferentially arranged filter holes on its outer sidewall;

[0007] An anti-backflow assembly is installed inside the pipe body to prevent liquid from flowing back into the pipe body. The anti-backflow assembly includes a conical plate fixedly installed inside the pipe body, a sealing plug and a pull rod passing through the center of the pipe body. The sealing plug and the pull rod both pass through the middle part of the conical plate. The sealing plug and the pull rod are fixedly connected. A plurality of surrounding settling balls are fixedly installed on the side of the sealing plug away from the pull rod. Each settling ball is located inside the pipe body.

[0008] Furthermore, the pipe body is equipped with an anti-winding component, which is used to clean the filter holes.

[0009] Furthermore, the tube body is fixedly equipped with multiple nozzles communicating with each of the filter holes. The anti-winding assembly includes a central rod passing through the center of the tube body and two brushes symmetrically installed on the outside of the tube body. Multiple arc-shaped fan blades are fixedly installed around the central rod. Each arc-shaped fan blade is located inside the tube body with its inner arc surface facing the nozzle. One end of the central rod is fixedly equipped with a base plate located outside the tube body. A slot is symmetrically opened on the base plate. Each brush is fixedly equipped with a card plate passing through the slot.

[0010] Furthermore, a groove is provided in the middle part of the central rod, which is fitted onto the outside of the pull rod.

[0011] Furthermore, a collar is fitted around the outside of the tube body, and a second slot is symmetrically opened on the outside of the collar. A second card plate, which is fixedly connected to the brush, passes through the second slot.

[0012] Furthermore, a water outlet is provided at the top of the pipe.

[0013] Furthermore, a connector communicating with the water outlet is fixedly installed at the top of the pipe body.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of water filter holes and anti-backflow components, can achieve the effect of automatic anti-backflow protection for the extracted liquid, preventing the freshly extracted liquid from flowing back into the original liquid through the extraction equipment and water filter pipe, and preventing the unextracted liquid in the container from being mixed or contaminated. This is beneficial for protecting the liquid and can save the cost of using valves and setting up related control devices.

[0016] 2. Furthermore, by incorporating filter holes, anti-winding components, and nozzles, this utility model can achieve the effect of preventing weeds from entangled on the outside of the filter pipe through the impact of water flow. This prevents the filter pipe from becoming clogged and thus hinders rapid water filtration, thereby improving the functionality of the filter pipe during use. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an anti-winding and anti-backflow water filter pipe.

[0026] The specific technical solution includes pipe body 1 and anti-backflow component 3;

[0027] like Figure 1-3 As shown, the outer sidewall of the pipe body 1 has multiple surrounding filter holes 2, which facilitate the filtration of water flowing into the pipe body 1. An anti-backflow assembly 3 is installed inside the pipe body 1 to prevent liquid from flowing back into the pipe body 1. The anti-backflow assembly 3 includes a conical plate 301 fixedly installed inside the pipe body 1, a sealing plug 302 penetrating the center of the pipe body 1, and a pull rod 303. The conical plate 301 provides convenient support for the sealing plug 302. The sealing plug 302 can seal the top of the conical plate 301, and the pull rod 303 can limit the sealing plug 302. The sealing plug 302 and the pull rod 303 are both inserted in the middle part of the conical plate 301. The sealing plug 302 and the pull rod 303 are fixedly connected. Multiple sinking balls 304 are fixedly installed on the side of the sealing plug 302 away from the pull rod 303. The sinking balls 304 can exert downward pressure on the sinking sealing plug 302. Each sinking ball 304 is located inside the tube body 1.

[0028] The pipe body 1 is placed vertically inside the water flow, with the smaller opening of the conical plate 301 facing upwards and the larger opening facing downwards. When the pumping device is activated to pump water into the pipe body 1, the negative pressure causes the sealing plug 302 to be pulled out from the top of the conical plate 301. The pull rod 303 can pull the sealing plug 302, which can be limited. The sealing plug 302 can limit the settling ball 304, preventing the settling ball 304 from blocking the outlet 11. Then, when the water flows through the filter holes 2 into the area below the conical plate 301 inside the pipe body 1, the filter holes 2 can filter impurities and weeds in the water flow, preventing weeds from entering the pipe body 1 and causing blockage. Water can flow through the conical plate 301 into the pumping device, facilitating pumping activities. After pumping is completed, the water flow inside the pipe body 1 ceases. Then, the sealing plug 302, pull rod 303, and sinker ball 304 descend due to gravity. The water flow above the conical plate 301 inside the pipe body 1 exerts downward pressure on the sealing plug 302, and the water flow inside the sinker ball 304 presses it down. The gravity of the water flow inside the sinker ball 304 increases the downward pressure on the sealing plug 302, allowing the sealing plug 302 to quickly press down into the conical plate 301 and block it, preventing the water flow inside the pumping device from flowing back into the pipe body 1.

[0029] like Figure 1-2 and Figure 4As shown, the pipe body 1 is equipped with an anti-winding component 4, which is used to clean the filter holes 2. Multiple nozzles 5, connected to each filter hole 2, are fixedly installed inside the pipe body 1. The water jets from the nozzles 5 generate a rotational force, which drives the arc-shaped fan blades 403 to rotate. The anti-winding component 4 includes a central rod 401 inserted into the center of the pipe body 1 and two brushes 402 symmetrically installed outside the pipe body 1. The central rod 401 supports the arc-shaped fan blades 403, and the brushes 402 clear weeds and impurities from inside the filter holes 2. Multiple arc-shaped fan blades 403 are fixedly mounted on the outside of the tube body 1. The arc-shaped fan blades 403 can drive the central rod 401 to rotate. Each arc-shaped fan blade 403 is located inside the tube body 1 and its inner arc surface faces the nozzle 5. One end of the central rod 401 is fixedly mounted with a base plate 404 located outside the tube body 1. The slot 6 opened on the base plate 404 can fix the card plate 405. The slots 6 are symmetrically opened on the base plate 404. Each brush 402 is fixedly mounted with a card plate 405 that passes through the slot 6. The card plate 405 can support the brush 402.

[0030] When the water flow inside the filter hole 2 flows rapidly into the nozzle 5, the water flow inside the nozzle 5 sprays out into the pipe body 1. Since the nozzles 5 are all inclined towards the inner arc surface of the arc-shaped fan blade 403, the water flow sprayed from each nozzle 5 can form a swirling flow inside the pipe body 1 and impact the arc-shaped fan blade 403. The rotation of the arc-shaped fan blade 403 can drive the central rod 401 to rotate around the central axis of the pipe body 1. The rotation of the central rod 401 can drive the base plate 404 to rotate. The base plate 404 can drive the slot 6 to rotate. The slot 6 can drive the plate 405 to rotate. The plate 405 can drive the brush 402 to rotate around the outer wall of the pipe body 1. The rotation of the brush 402 can clean the impurities on the outside of the pipe body 1, prevent weeds from getting tangled on the outside of the pipe body 1, and at the same time brush away the impurities remaining inside the filter hole 2.

[0031] like Figure 2 As shown, a groove 7 is provided in the middle part of the center rod 401 and is sleeved on the outside of the pull rod 303. The groove 7 can limit the pull rod 303.

[0032] like Figure 1 As shown, a collar 8 is sleeved on the outside of the tube body 1. A second groove 9 is opened on the collar 8 to fix the second plate 10. The second groove 9 is symmetrically opened on the outside of the collar 8. The second plate 10, which is fixedly connected to the brush 402, passes through the second groove 9. The second plate 10 can support the top of the brush 402 and prevent the top of the brush 402 from being squeezed, tilted and away from the tube body 1.

[0033] By prying open the first card plate 405 and the second card plate 10, the first card plate 405 and the second card plate 10 can be pulled out from the first card slot 6 and the second card slot 9 respectively, making it easy to disassemble the brush 402.

[0034] like Figure 1-2 As shown, a water outlet 11 is provided at the top of the pipe body 1, which can conveniently draw water from inside the pipe body 1.

[0035] like Figure 1-2 As shown, the top of the pipe body 1 is fixedly equipped with a connector 12 that communicates with the water outlet 11, and the connector 12 can be easily connected to the pumping device.
