Some manhole covers can also drain water downward.
[0003] Currently, there are usually many manholes built in parks. Because there are often a lot of fallen leaves and other sundries on the ground in the park, these fallen leaves are very easy to directly flow into the manhole and be discharged into the drainage pipe. When a large amount of fallen leaves and other sundries accumulate in the drainage pipe, it is easy to cause blockage, and it is very inconvenient to clean up later. Summary of the Invention
[0004] The utility model provides a clogging prevention device, which can prevent sundries such as leaves from blocking the drainage pipe, and can automatically ensure normal drainage, and it is also very convenient to clean up sundries such as leaves later.

[0006] A manhole cover is installed on the top of the manhole; an inner partition is fixed inside the manhole; three filter covers are equidistantly arranged on the top of the inner partition; a floating block is slidably arranged in each of the three filter covers; a plurality of cleaning scrapers are equidistantly arranged on the front and rear sides of the floating block.
[0007] In at least some embodiments, the cleaning scrapers are all inclined plates, and the side of the cleaning scraper close to the floating block is high, and the side of the cleaning scraper far from the floating block is low.
[0008] In at least some embodiments, a cavity is provided inside each of the filter covers, and the floating block can slide up and down in the cavity inside the filter cover.
[0009] In at least some embodiments, the cleaning scrapers between the adjacent front and rear floating blocks are connected to each other to form a V-shaped plate, and a round rod is also connected between the adjacent left and right V-shaped plates.
[0010] In at least some embodiments, three longitudinally penetrating long strip-shaped openings are equidistantly arranged on the inner partition, and the three longitudinally penetrating long strip-shaped openings are respectively located directly below the three filter covers.
[0011] In at least some embodiments, the floating block is a rectangular block made of hollow ABS material, and the cleaning scrapers are also rectangular plates made of ABS material.
[0012] In at least some embodiments, a plurality of vertical opening grooves penetrating front to back are evenly spaced on the front and rear outer walls of the filter cover, and the cleaning scraper can move up and down in the vertical opening grooves on the front and rear outer walls of the filter cover.
[0013] The utility model provides an anti-blocking device, which has the following beneficial effects:
[0014] The filter cover in the utility model cooperates with the cleaning scrapers on the front and rear sides of the floating block to block the leaves and other debris entering the sewer well, preventing the leaves and other debris from being directly discharged into the sewer pipe. In addition, when draining water, the floating block and the cleaning scraper can also rely on the buoyancy to clean the leaves and other debris on the outside of the filter cover, ensuring that rainwater can flow downward normally. The device can prevent the sewer pipe from being blocked by leaves and other debris, and can automatically ensure normal drainage, which is also very convenient for cleaning leaves and other debris at a later time.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present utility model in conjunction with the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
[0027] Embodiment 1: Please refer to Figures 1 to 6 :
[0028] The present utility model provides a clogging prevention device, including: a sewer well 1;
[0029] A manhole cover 2 is installed on the top of the sewer well 1. The sewer well 1 is used to support the manhole cover 2 and the inner partition 3. The manhole cover 2 is used to cover the opening at the top of the sewer well 1 to prevent people from falling. An inner partition 3 is fixed inside the sewer well 1. The inner partition 3 is used to support the filter cover 4. During rainy weather, rainwater will first accumulate in the cavity at the top of the inner partition 3. When the accumulated rainwater is relatively large, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4. At this time, the rainwater in the cavity at the top of the inner partition 3 can flow downward through the long strip-shaped openings on the inner partition 3 into the drain pipe. Three filter covers 4 are equidistantly arranged at the top of the inner partition 3. The filter cover 4 can slidably support the floating block 5. When the accumulated rainwater in the cavity at the top of the inner partition 3 is relatively large, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4, so that the rainwater in the cavity at the top of the inner partition 3 is discharged downward. Moreover, when the floating block 5 moves upward, the cleaning scrapers 6 on its front and rear sides will also move upward synchronously, so as to clean the leaves and other sundries covering the outer walls on the front and rear sides of the filter cover 4, and prevent the vertical opening grooves on the front and rear sides of the filter cover 4 from being blocked, which affects the downward discharge of rainwater. A floating block 5 is slidably arranged in each of the three filter covers 4. In the normal state, the floating block 5 will slide down to the bottom in the cavity inside the filter cover 4. At this time, the floating block 5 will close the three long strip-shaped openings on the inner partition 3. Therefore, rainwater will accumulate in the cavity at the top of the inner partition 3. When the accumulated rainwater is relatively large, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4. At this time, the rainwater in the cavity at the top of the inner partition 3 can flow downward through the long strip-shaped openings on the inner partition 3 into the drain pipe. A plurality of cleaning scrapers 6 are equidistantly arranged on the front and rear sides of the floating block 5. When the floating block 5 moves upward, the cleaning scrapers 6 on its front and rear sides will also move upward synchronously, so as to clean the leaves and other sundries covering the outer walls on the front and rear sides of the filter cover 4, and prevent the vertical opening grooves on the front and rear sides of the filter cover 4 from being blocked, which affects the downward discharge of rainwater.
[0030] In the embodiments of the present disclosure, as Figure 3 ,Figure 4 and Figure 6 As shown in Figure 6 , the cleaning scraper 6 is an inclined plate, and the side of the cleaning scraper 6 close to the floating block 5 is high, while the side away from the floating block 5 is low. Therefore, when the cleaning scraper 6 moves upward, it can push the sundries such as leaves on the front and rear outer walls of the filter cover 4 outward. The inclined cleaning scraper 6 is more convenient for the sundries such as leaves to move away from the front and rear outer walls of the filter cover 4.
[0031] In the embodiment of the present disclosure, as Figure 3 and Figure 4 shown, a cavity is provided inside the filter cover 4, and the floating block 5 can slide up and down in the cavity inside the filter cover 4. In the normal state, the floating block 5 will slide down to the bottom in the cavity inside the filter cover 4. At this time, the floating block 5 will close the three long strip-shaped openings on the inner partition plate 3. Therefore, rainwater will accumulate in the cavity at the top of the inner partition plate 3. When there is more accumulated rainwater, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4. At this time, the rainwater in the cavity at the top of the inner partition plate 3 can flow downward through the long strip-shaped openings on the inner partition plate 3 into the drain pipe.
[0032] In the embodiment of the present disclosure, as Figures 2 to 4 and Figure 6 shown, the cleaning scrapers 6 between the adjacent front and rear floating blocks 5 are connected to each other to form a V-shaped plate, and a round rod is connected between the adjacent left and right V-shaped plates. Therefore, the three floating blocks 5 can be connected together, which is convenient for the three floating blocks 5 to float synchronously to increase the water discharge, and the cleaning scrapers 6 and the round rod between them can also block the sundries such as leaves.
[0033] In the embodiment of the present disclosure, as Figures 3 to 5 shown, three long strip-shaped openings penetrating up and down are equidistantly arranged on the inner partition plate 3, and the three long strip-shaped openings are respectively located directly below the three filter covers 4. When there is more accumulated rainwater in the cavity at the top of the inner partition plate 3, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4, so that the rainwater in the cavity at the top of the inner partition plate 3 is discharged downward through the three long strip openings on the inner partition plate 3.
[0034] In the embodiment of the present disclosure, as Figure 3 and Figure 4As shown, a number of vertically penetrating vertical opening grooves are equidistantly arranged on the front and rear outer walls of the filter cover 4, and the cleaning scraper 6 can move up and down in the vertical opening grooves on the front and rear outer walls of the filter cover 4. When draining water, rainwater will first enter the internal cavity through the vertical opening grooves on the front and rear outer walls of the filter cover 4, and then can be discharged downward through the long strip openings on the inner partition 3. Moreover, when the floating block 5 moves upward, the cleaning scrapers 6 on its front and rear sides will also move upward in the vertical opening grooves on the front and rear outer walls of the filter cover 4, so as to be able to clean the sundries such as leaves covering the front and rear outer walls of the filter cover 4, and avoid the blockage of the vertical opening grooves on the front and rear sides of the filter cover 4, which affects the downward discharge of rainwater.
[0035] Embodiment 2, on the basis of Embodiment 1, as Figures 1 to 6 shown, the floating block 5 is a rectangular block made of hollow ABS material, and the cleaning scrapers 6 are also rectangular plates made of ABS material. When there is a large accumulation of rainwater in the cavity at the top of the inner partition 3, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the internal cavity of the filter cover 4, so that the rainwater in the cavity at the top of the inner partition 3 can be discharged downward. Moreover, when the floating block 5 moves upward, the cleaning scrapers 6 on its front and rear sides will also move upward synchronously, so as to be able to clean the sundries such as leaves covering the front and rear outer walls of the filter cover 4, and avoid the blockage of the vertical opening grooves on the front and rear sides of the filter cover 4, which affects the downward discharge of rainwater. The weight of the ABS material is relatively light, so it is more convenient for the floating block 5 and the cleaning scraper 6 to be pushed upward by the buoyancy of water, and the hollow floating block 5 can also provide greater buoyancy.
[0036] Working principle of this embodiment: During installation, the sewer well 1 can be fixed at the sewer position in the park first, and the bottom of the sewer well 1 is connected to the drainage pipe below the ground. Then, the manhole cover 2 can be installed inside the top of the sewer well 1. During rainy weather, rainwater will first flow into the cavity at the top of the inner partition 3 through the opening grooves on the manhole cover 2. Because in the normal state, the floating block 5 will slide to the bottom in the cavity inside the filter cover 4. At this time, the floating block 5 will close the three long strip-shaped openings on the inner partition 3. Therefore, rainwater will accumulate in the cavity at the top of the inner partition 3. When there is more accumulated rainwater, the buoyancy provided by the rainwater can push the floating block 5 to move upward in the cavity inside the filter cover 4. At this time, the rainwater in the cavity at the top of the inner partition 3 can flow downward through the long strip-shaped openings on the inner partition 3 into the drain pipe. During drainage, the manhole cover 2 can block some leaves and other sundries in the park. There will also be some leaves and other sundries that enter the cavity at the top of the inner partition 3. At this time, these sundries will be intercepted on the top of the cleaning scraper 6. When the floating block 5 moves upward, the cleaning scrapers 6 on its front and rear sides will also move upward synchronously, so as to clean the leaves and other sundries covering the outer walls on the front and rear sides of the filter cover 4, avoiding the blockage of the vertical opening grooves on the front and rear sides of the filter cover 4 and affecting the downward discharge of rainwater. When it is necessary to clean the leaves and other impurities in the sewer well 1 later, only need to remove the manhole cover 2 first, and then the impurities in the sewer well can be taken out through the opening at the top of the sewer well 1.
