[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a municipal engineering drainage structure, including a pipe 1, the main channel for municipal drainage, responsible for transporting water flow. A fixed box 2 is fixedly connected to the right side of the pipe 1, serving as the mounting carrier for a cleaning mechanism, providing space for the movement of the cleaning mechanism, and connected to a collection box 3. Debris enters the collection box 3 through the discharge hole 46 at the bottom of the fixed box 2. The right side of the pipe 1 communicates with the interior of the fixed box 2. The collection box 3 is fixedly connected to the bottom of the fixed box 2 for collecting debris cleaned from the pipe 1. A cleaning mechanism is provided on the inner wall of the pipe 1, including a cleaning component and a power component. The cleaning component includes a grille 41, which is L-shaped to intercept debris in the water flow. The grille 41 is fixedly connected to... A support rod 42 is slidably connected to the inner wall of the fixed box 2, and multiple sets of support rods 42 are provided. A connecting plate 45 is fixedly connected to the right side of the multiple sets of support rods 42. By moving the connecting plate 45, the multiple sets of support rods 42 are moved. The multiple sets of support rods 42 can increase the stability of the baffle plate 44 and the scraper 43. A baffle plate 44 is fixedly connected to the outside of the support rods 42. When the grid 41 is not cleaned, it is used to seal the right side of the pipe 1 to prevent water from entering the fixed box 2 and the collection box 3, and to prevent the backflow of debris. When the baffle plate 44 is reset, it can scrape the impurities remaining inside the fixed box 2 into the collection box 3 through the discharge hole 46, which improves the cleaning efficiency and reduces maintenance costs and labor intensity.

[0032] Reference Figure 2 - Figure 4 The baffle plate 44 slides on the inner wall of the fixed box 2. The support rod 42 is fixedly connected to the left side of the scraper 43, which is used to scrape off the debris on the grid 41. The scraper 43 is set on the lower side of the grid 41, which can reduce the accumulation of impurities on the scraper 43. The scraper 43 slides on the outer side of the grid 41. The lower part of the fixed box 2 and the upper part of the collection box 3 are provided with discharge holes 46, which facilitates the entry of debris from the fixed box 2 into the collection box 3. The power component includes an electric telescopic rod 51. The electric telescopic rod 51 is set on the upper inner wall of the fixed box 2. After the electric telescopic rod 51 is started, it can drive the connecting plate 45, the support rod 42, the scraper 43 and the baffle plate 44 to move, providing power for cleaning debris. The output shaft of the electric telescopic rod 51 is fixedly connected to the right side of the connecting plate 45, which is used to connect the output shaft of the electric telescopic rod 51 and the connecting plate 45. The connecting piece 52 is fixedly connected to the outer side of the connecting plate 45.

[0033] Furthermore, the outer side of the baffle plate 44 is inserted into the inner wall of the pipe 1, and a sealing gasket is provided on the outer side of the baffle plate 44 to increase the sealing between it and the pipe 1. A sealing ring is provided on the inner wall of the fixed box 2 near the support rod 42 to increase the sealing between the support rod 42 and the fixed box 2. The lower part of the scraper 43 is provided with a long strip shape. The width of the long strip shape of the scraper 43 is the same as the size of the gap on the grid 41. When the scraper 43 moves to the right side of the grid 41, the long strip shape on the scraper 43 can be engaged in the gap on the grid 41 to seal the right side of the grid 41 and prevent impurities from accumulating on the right side of the grid 41. A filter plate 6 is fixedly connected to the left side of the inner wall of the collection box 3 to filter impurities in the collection box 3 and prevent blockage of the drain pipe 7. The collection box 3 and the inner wall of the pipe 1 are connected through the drain pipe 7. There are multiple sets of drain pipes 7, which are inclined to allow the water in the collection box 3 that has been filtered by the filter plate 6 to be smoothly discharged back to the pipe 1 by gravity, maintaining the normal operation of the drainage system and preventing water accumulation in the collection box 3.

[0034] Reference Figure 1 , Figure 5 and Figure 6 A limiting component is provided on the front side of the collection box 3. The limiting component includes a movable door 81, which is rotatably connected to the front side of the collection box 3 for easy opening and cleaning of debris. A limiting member 82 is slidably connected to the inner wall of the right side of the movable door 81. It is L-shaped and can be inserted into the slot 84 to limit the movable door 81. There are two sets of limiting members 82, and the endpoints of the two sets of limiting members 82 are set as inclined surfaces. The inclined surfaces facilitate the insertion of the limiting members 82 into the inner wall of the slot 84. The limiting members 82 and the movable door 81 are elastically connected by compression springs 83. There are two sets of compression springs 83, which are connected to the two sets of limiting members 82 respectively, to apply pressure to the limiting members 82, thereby maintaining the stability of the movable door 81. The inner wall of the collection box 3 has a slot 84, and the limiting member 82 is inserted into the inner wall of the slot 84. A sealing strip is provided on the rear side of the movable door 81 to increase the sealing between the movable door 81 and the collection box 3.

[0035] Working principle: When it is necessary to clean the debris attached to the grille 41, the electric telescopic rod 51 on the upper inner wall of the fixed box 2 is activated. The output shaft of the electric telescopic rod 51 extends, driving the connecting plate 45 to move to the right through the connector 52, thereby driving multiple sets of support rods 42 to slide to the right simultaneously. At this time, the blocking plate 44 on the outside of the support rod 42 slides on the inner wall of the fixed box 2, gradually releasing the blockage of the pipe 1.

[0036] Meanwhile, the scraper 43, which is fixedly connected to the left side of the support rod 42, also slides to the right on the outside of the grille 41, scraping off the debris attached to the grille 41 and pushing it towards the fixed box 2. After the debris is scraped off, it enters the collection box 3 through the discharge hole 46 between the fixed box 2 and the collection box 3 with the help of the impact force of the water flow in the pipe 1. The filter plate 6 on the left side of the inner wall of the collection box 3 can filter the water entering the collection box 3, intercepting impurities in the water and preventing these impurities from entering the drain pipe 7 and causing blockage. The filtered water is smoothly discharged back to the pipe 1 through the drain pipe 7 under the action of gravity, maintaining the normal circulation of the drainage system and preventing water accumulation in the collection box 3. After cleaning, the electric telescopic rod 51 retracts, driving all components to reset, and the baffle plate 44 closes the pipe 1 again. During the reset process, the baffle plate 44 can scrape the remaining impurities inside the fixed box 2 into the collection box 3.

[0037] When cleaning the collection box 3, pull the two sets of limiting parts 82, compress the spring 83, and the limiting parts 82 disengage from the slots 84 on the inner wall of the collection box 3. At this time, the movable door 81 can be opened to facilitate the cleaning of the debris accumulated in the collection box 3. The sealing strip on the back of the movable door 81 can ensure the sealing of the collection box 3 when closed to prevent sewage leakage.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
