[0020] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:
[0021] Please refer to Figure 1-Figure 3 .
[0022] The utility model discloses a water supply and drainage filtering device, comprising a water pipe 1, a manhole cover 2, a cover plate 3 and a filter box 4;
[0023] The water pipe 1 includes a first pipe 11, a second pipe 12, and a third pipe 13. A first mounting groove 111 is defined at one end of the first pipe 11. The diameter of the first mounting groove 111 is greater than the inner diameter of the first pipe 11, and the inner contour of the first mounting groove 111 is the same as the outer contour of the manhole cover 2. A second mounting groove 121 is defined at one end of the second pipe 12. The diameter of the second mounting groove 121 is greater than the inner diameter of the second pipe 12, and the inner contour of the second mounting groove 121 is the same as the outer contour of the cover plate 3.
[0024] Furthermore, the other end of the first pipe 11 is connected to the middle of the second pipe 12, and rainwater enters the first pipe 11 from one end of the first pipe 11, and is introduced into the second pipe 12 by the first pipe 11 through the other end of the first pipe 11; in this embodiment, the third pipe 13 is preferably U-shaped, one end of the third pipe 13 is connected to the other end of the second pipe 12, and the other end of the third pipe 13 is connected to the external pipe network, and rainwater is introduced into the third pipe 13 by the second pipe 12 through the other end of the second pipe 12. The U-shaped design of the third pipe 13 can allow the third pipe 13 to retain accumulated water inside when there is no water flowing through it. The accumulated water can keep the third pipe 13 in a sealed state, so that the odor in the external pipe network cannot pass through the third pipe 13, thereby avoiding the problem of backodor.
[0025] Please refer to Figure 3 and Figure 4 .
[0026] The manhole cover 2 is provided with a plurality of drainage grooves arranged at intervals. The drainage grooves penetrate the manhole cover 2. The manhole cover 2 is installed in the first installation groove 111. Rainwater on the road can pass through the drainage grooves on the manhole cover 2 and enter the first pipe 11.
[0027] A handle 31 is provided on the top of the cover plate 3 , a connecting rod 32 is fixedly connected to the bottom of the cover plate 3 , an anti-fall rope 33 is fixedly connected to the bottom of the cover plate 3 , and the connecting rod 32 is fixedly connected to the filter box 4 .
[0028] The filter box 4 includes a bottom plate 41 and a cylinder 42. The connecting rod 32 is fixedly connected to the bottom plate 41, and the anti-fall rope 33 is fixedly connected to the bottom plate 41. Two paddles 411 are rotatably connected to the outside of the bottom plate 41. One end of the paddle 411 is rotatably connected to the bottom plate 41. A buckle 412 is rotatably connected to the paddle 411. The connection between the buckle 412 and the paddle 411 is located in the middle of the paddle 411. A plurality of first filter holes are formed on the bottom plate 41. The first filter holes pass through the bottom plate 41. An annular groove 413 is formed on the top of the bottom plate 41.
[0029] The cylinder 42 is provided with a waist, which is close to the bottom of the cylinder 42. The diameter of the waist of the cylinder 42 is smaller than the inner diameter of the second pipe 12. The diameter of the widest part of the cylinder 42 is equal to the inner diameter of the second pipe 12, so that the rainwater in the second pipe 12 can only pass through the filter box 4 to enter the third pipe 13; a plurality of second filter holes are opened on the cylinder 42, and the second filter holes are located on the waist of the cylinder 42. Two hooks 421 extend from the outside of the cylinder 42; the bottom of the cylinder 42 is clamped on the ring shaped slot 413, the buckle 412 is hooked into the hook 421, the paddle 411 is pulled to pull the buckle 412, thereby fixing the cylinder 42 on the bottom plate 41, the filter box 4 is inserted into the second pipe 12, the filter box 4 is located in the second pipe 12, the cover plate 3 is installed in the second installation slot 121, below the other end of the first pipe 11, one end of the second pipe 12 extends to the sidewalk, the cover plate 3 seals one end of the second pipe 12 to prevent pedestrians from stepping on it, and it is also convenient for workers to clean the filter box 4.
[0030] Rainwater carrying leaves and branches enters the cylinder 42. The bottom plate 41 and the cylinder 42 intercept the leaves and branches and trap them in the filter box 4. The rainwater passes through the first filter hole and the second filter hole, thereby filtering out the impurities mixed in the rainwater. Since each layer of the cylinder 42 is provided with a second filter hole, when the leaves and branches are piled up in the cylinder 42, the rainwater can also flow out from the second filter hole on each layer.
[0031] When it is necessary to clean the leaves and branches in the filter box 4, the worker pulls the handle 31 of the cover plate 3 to pull the filter box 4 out of the second pipe 12, and moves the paddle 411 to disengage the buckle 412 from the hook 421, so that the cylinder 42 can be separated from the bottom plate 41, making it easier to clean the leaves and branches in the cylinder 42; after cleaning, the cylinder 42 is installed back on the bottom plate 41, the buckle 412 is engaged with the hook 421, the filter box 4 is installed back into the second pipe 12, and the cover plate 3 is put back into the second installation groove 121;
[0032] After long-term use, the connecting rod 32 is prone to rust. When the connecting rod 32 breaks, the filter box 4 will fall into the third pipe 13 and is not easy to remove. The anti-fall rope 33 can facilitate workers to pull the anti-fall rope 33 to remove the filter box 4 from the third pipe 13 to avoid clogging the third pipe 13.
[0033] The utility model provides a water supply and drainage filtering device. When rainwater enters a first pipe, the first pipe guides the rainwater into the middle part of a second pipe. The rainwater carries leaves and branches into a filter box. The filter box intercepts the leaves and branches in the filter box. The rainwater passes through the filter box to filter the leaves and branches in the rainwater. When the leaves and branches in the filter box are full, the connecting rod and the filter box are removed from the second pipe in turn by pulling the cover plate. After the leaves and branches in the filter box are cleaned, the filter box is installed back to its original position, so that the filter box is easy to clean.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
