Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to an anti-blocking device for a drainage valve. Background Art

[0002] The background of anti-blocking equipment for drain valves involves the daily maintenance and operation of drainage systems and the need to solve the problem of drainage system blockage. In urban and industrial environments, drainage systems are key components to ensure the smooth operation of infrastructure and are responsible for removing sewage, rainwater and other liquids generated by buildings, roads and other facilities.

[0003] Existing technologies include: filter screens or baskets. A filter screen or basket is set at the drain outlet to block large particles from entering the drain pipe. A grille structure is set at the drain outlet to prevent large particles from entering the drain pipe. A reverse anti-blocking valve can prevent sewage from flowing back, but the blocking effect on solid debris is limited. The filter can filter out smaller particles, fibers and soft debris more finely. The hydraulic rotary anti-blocking device uses the rotational force of the water flow to bring solid particles and debris into the rotating chamber, and then deposits the solid particles on the wall through centrifugal force.

[0004] The existing filtering equipment uses a large number of parts during installation to ensure the stability of the pipeline installation. The use of a large number of parts requires professionals to use professional tools for installation. The use of a large number of parts also increases the probability of errors during the installation process, which not only increases the time cost of drainage system construction, but also affects the overall progress and quality of the project. Therefore, a drainage valve anti-blocking device is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides an anti-blocking device for a drain valve, aiming to improve the problem in the prior art that a large number of parts are used in the installation of the anti-blocking device, which increases the probability of errors and prolongs the installation period.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-blocking device for a drain valve, comprising an anti-blocking pipe, a filter assembly is arranged on the upper part of the anti-blocking pipe, a pipeline is slidably connected to the bottom of the anti-blocking pipe, a limiting plate is fixedly connected to the bottom of the anti-blocking pipe, a push plate 1 is threadedly connected to the middle part of the anti-blocking pipe, a push plate 2 is slidably connected to the middle part of the push plate 1, connecting blocks are fixedly connected to the left and right sides of the push plate 2, a clamping block is rotatably connected to the middle part of the two connecting blocks, a spring is fixedly connected to the adjacent side of the upper ends of the two clamping blocks, and adjacent ends of the two springs are fixedly connected to the inside of the push plate 2.

[0007] Furthermore, the filter assembly includes a screen, which is fixedly connected to the upper inner wall of the anti-blocking tube, a support frame is fixedly connected to the inside of the screen, a rotating rod is rotatably connected to the middle of the screen, a cleaning rod is fixedly connected to the upper end of the rotating rod, and a fan blade is fixedly connected to the lower end of the rotating rod.

[0008] Furthermore, the left and right sides of the pipeline are provided with card slots.

[0009] Furthermore, a rotation groove is opened in the middle of the push plate 1, and the push plate 2 rotates inside the rotation groove.

[0010] Furthermore, a thread is provided on the outer periphery of the middle portion of the anti-blocking tube.

[0011] Furthermore, the left and right sides of the second push plate are provided with fixing grooves, and the adjacent ends of the two springs are fixedly connected inside the fixing grooves.

[0012] Furthermore, the screen is made of polypropylene.

[0013] Furthermore, the support frame is made of aluminum alloy.

[0014] The utility model has the following beneficial effects:

[0015] In the utility model, the two card slots of the pipeline are aligned with the positions of the two card blocks, and then the pipeline is pushed into the anti-blocking pipe, and the upper ends of the two card blocks are pressed at the same time. The two card blocks will squeeze the two springs to shrink inside the push plate 2, and the lower ends of the two card blocks will open. When the two card blocks can be stuck in the two card slots, the two card blocks are released to allow the two card blocks to be stuck in the two card slots, and then the push plate 1 is rotated. At this time, the push plate 1 will pull the push plate 2 to move upward, and the push plate 2 will pull the two connecting blocks to move upward. The two connecting blocks will pull the two card blocks to move upward. At this time, the two card blocks can pull the pipeline to clamp the anti-blocking pipe, thereby realizing the rapid installation of the anti-blocking pipe.

[0016] In the utility model, during the use of the anti-blocking pipe, fine particles will continue to adhere to the surface of the screen. When water flows through the screen and impacts the fan blades, the fan blades will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the cleaning rod to rotate on the surface of the screen. When the cleaning rod rotates, it can continuously scrape off the attached particles on the surface of the screen. In order to ensure the long-term use of the device, the screen is made of polypropylene, which can resist chemicals and oxidation in the water. The support frame is made of aluminum alloy, and the aluminum alloy provides structural support and stability. BRIEF DESCRIPTION OF THE DRAWINGS

The two connecting blocks 5 are used to connect and pull the two clamping blocks 6 to move. The middle parts of the two connecting blocks 5 are rotatably connected with clamping blocks 6. The two clamping blocks 6 are used to be clamped in the inside of the clamping grooves on the left and right sides of the pipe 8. The upper ends of the two clamping blocks 6 are fixedly connected with springs 7 on one side. The two springs 7 are used to push the two clamping blocks 6 back. The two springs 7 are fixedly connected to the inside of the push plate 2 4 at one end. The push plate 2 4 is provided with fixed grooves on the left and right sides. The two springs 7 are fixedly connected to the inside of the fixed grooves at one end. When the two clamping blocks 6 are squeezed and contracted, the two springs 7 will contract and embed into the inside of the two fixed grooves. When the two clamping blocks 6 lose pressure, the two springs 7 will push the two clamping blocks 6 back and be clamped in the inside of the two clamping grooves.

[0025] Reference Figure 1 and Figure 4 The filter assembly includes a screen 9, which is made of polypropylene. Polypropylene has good corrosion resistance and durability, so the screen 9 can resist chemicals and oxidation in the water, ensuring long-term filtration efficiency. The screen 9 is fixedly connected to the upper inner wall of the anti-blocking pipe 1. A support frame 11 is fixedly connected inside the screen 9. The support frame 11 is made of aluminum alloy. The aluminum alloy provides structural support and stability, which can ensure that the support frame 11 can withstand external pressure and ensure that the shape and structure of the outer screen 9 are stable and not deformed. The middle part of the screen 9 is rotatably connected There is a rotating rod 12, the upper end of which is fixedly connected to a cleaning rod 10, a brush is provided at the lower part of the cleaning rod 10, and the lower end of the rotating rod 12 is fixedly connected to a fan blade 13. The rotating rod 12 is used to connect the cleaning rod 10 and the fan blade 13. When the water flows through the screen 9 and impacts the fan blade 13, the fan blade 13 will rotate under the push of the water flow. At this time, the rotating rod 12 will drive the cleaning rod 10 to rotate on the upper surface of the screen 9. During the rotation of the cleaning rod 10, the attached particles on the surface of the screen 9 will be continuously cleaned to prevent the attached particles from clogging the screen 9.

[0026] Working principle: When installing the device on the pipeline 8, it is necessary to align the two slots with the positions of the two blocks 6, and then push the pipeline 8 into the anti-blocking pipe 1, and then squeeze the two blocks 6. The two springs 7 will be squeezed and contracted. At this time, the lower ends of the two blocks 6 will open to both sides. When the two blocks 6 can be stuck in the two slots, release the two blocks 6. At this time, the two springs 7 will relax and push the two blocks 6 back. At this time, the lower ends of the two blocks 6 will be stuck in the two slots, and then rotate the push plate 1 3. The push plate 1 3 will rotate at the lower end of the anti-blocking pipe 1. At this time, the push plate 1 3 will spirally rise, and the push plate 1 3 will pull the push plate 2 4 to rise. When the pipeline 8 is firmly stuck in the lower part of the anti-blocking pipe 1, the push plate 1 3 will not be able to rotate. At this time, the push plate 1 3 will be locked, thereby completing the installation of the anti-blocking pipe 1. When the anti-blocking tube 1 is in use, the screen 9 at the upper end of the anti-blocking tube 1 will prevent foreign matter from entering the anti-blocking tube 1. During use, small solid particles will continue to adhere to the surface of the screen 9. When water flows through the screen 9 and impacts the fan blades 13, the fan blades 13 will rotate to drive the rotating rod 12 to rotate, and the rotating rod 12 will also drive the cleaning rod 10 to rotate. When the cleaning rod 10 rotates, it will continue to sweep the surface of the screen 9 to prevent a large number of small solid particles from adhering to the screen 9, causing the screen 9 to be blocked and affecting the drainage efficiency. In order to ensure the long-term filtration efficiency of the screen 9, the screen 9 is made of polypropylene, which has corrosion resistance and durability. In order to withstand the impact of water flow and prevent excessive water flow from deforming the screen 9, the support frame 11 can ensure that the screen 9 can withstand external pressure and ensure that the shape and structure of the outer screen 9 are stable and not deformed.
