[0046] The present invention will be further described below with reference to specific embodiments.

[0047] Example 1

[0048] refer to Figure 1 , Figure 2 As shown, this embodiment of a municipal pipe network drainage structure includes a pipe body 1 and a filter cylinder 3 and a scraper 4 disposed within the pipe body 1. The pipe body 1 has openings at its top and both ends. The filter cylinder 3 is placed inside the pipe body 1 through the top opening. The scraper 4 is placed inside the pipe body 1 through the openings at both ends, with the two scrapers 4 located on opposite sides of the filter cylinder 3, and the scraper 4 slidingly engaging with the inner wall of the pipe body 1. Additionally, a perforated cover plate 2 is provided at the top opening of the pipe body 1.

[0049] The filter cylinder 3 is connected to a first drive assembly for moving the filter cylinder 3 outside the pipe body 1, and the scraper 4 is connected to a second drive assembly for moving the scraper 4 outside the pipe body 1. The filter cylinder 3 moves vertically, and the scraper 4 moves horizontally.

[0050] Specifically, such as Figures 4-7 As shown, the first drive assembly includes a fixed cylinder 51 and an elastic element 52 disposed within the fixed cylinder 51. The fixed cylinder 51 is located at the center of the bottom of the pipe body 1, and the inner cavity of the fixed cylinder 51 communicates with the inner cavity of the pipe body 1. A top plate 53 is connected to the end of the fixed cylinder 51. The top plate 53 is located at the bottom of the filter cylinder 3 and is used to lift the filter cylinder 3 upward.

[0051] Specifically, in this embodiment, the elastic element 52 is preferably a compression spring, which is confined within the fixed cylinder 51 by the top plate 53. The top plate 53 and the fixed cylinder 51 can be threaded together, and the top plate 53 is connected to a rotating block 54, which is rotatably disposed within a through hole in the bottom wall of the filter cylinder 3. By rotating the rotating block 54, the top plate 53 can be disengaged from the fixed cylinder 51, the compressed spring is released, and the top plate 53 moves upward, thereby lifting the filter cylinder 3.

[0052] In order to ensure that the spring can smoothly lift the filter cartridge 3, the diameter of the top plate 53 needs to be greater than the diameter of the through hole on the bottom wall, that is, the top plate 53 can lift the filter cartridge 3 from the bottom. In addition, the top plate 53 and the rotating block 54 can be clamped. Specifically, the bottom of the rotating block 54 is provided with a boss, and the top of the top plate 53 is provided with a clamping groove matched with the boss. At the same time, the bottom of the top plate 53 is also provided with a mounting groove to facilitate the placement of the end of the compression spring therein, so as not to affect the rotation of the top plate 53.

[0053] As shown in Figure 7 , Figure 8 The filter cartridge 3 includes a water filling cavity 31 in the middle and a buffer cavity 32 on both sides, and the rotating block 54 is arranged on the bottom wall of the water filling cavity 31. Among them, the top of the water filling cavity 31 is provided with a water inlet, and the side of the buffer cavity 32 away from the water filling cavity 31 is provided with a water outlet.

[0054] The water filling cavity 31 and the buffer cavity 32 are connected with each other through the water filtering through hole 33, so as to ensure that the sundries in the rainwater can be intercepted under the condition that the rainwater can flow normally; in addition, the setting of the buffer cavity 32 is conducive to the sedimentation of the sludge in the rainwater, so that it is retained in the filter cartridge 3, to facilitate the unified cleaning in the later period.

[0055] As shown in Figure 3 , Figure 4 The second driving assembly includes a winding wheel 61 and a return member 62, wherein the winding wheel 61 is wound with a traction rope, one end of the traction rope is connected with the scraper 4. Rotating the winding wheel 61 can drive the scraper 4 to move to the opening at the end of the pipeline body 1 through the traction rope. One end of the return member 62 is connected with the inner wall of the pipeline body 1, and the other end is connected with the scraper 4. The return member 62 is preferably a spring, which can reset the scraper 4 to facilitate the use of the next cleaning.

[0056] As shown in Figure 5 , Figure 6 The inner wall of the pipeline body 1 is provided with a sliding groove 11, and the return member 62 is located in the sliding groove 11, thereby playing a certain guiding and limiting role. Of course, the traction rope can also pass through the sliding groove 11 to avoid affecting the use of other components by the traction rope.

[0057] At the same time, the inner wall of the pipeline body 1 is also provided with a placing groove 12, and the winding wheel 61 is rotatably arranged in the placing groove 12. Preferably, the placing groove 12 is arranged on the inner wall of the opening at the top of the pipeline body 1. In addition, the depth of the placing groove 12 needs to be greater than the thickness of the winding wheel 61, so as to avoid interference with the placement of the filter cartridge 3, so that the filter cartridge 3 can be closely combined with the inner cavity of the pipeline body 1.

[0058] AsFigure 9 As shown, the scraper 4 has multiple filter holes, and each end of the scraper 4 is provided with a limiting seat 41, which is located in the corresponding slide groove 11. Preferably, the size of the limiting seat 41 is adapted to the size of the slide groove 11 to ensure that the scraper 4 does not wobble during movement. In addition, the limiting seat 41 is provided with a connecting rod 42, and the reset member 62 and the traction rope are both connected to the connecting rod 42.

[0059] like Figure 10 As shown, the reel 61 is generally annular with a U-shaped cross-section. The outer peripheral wall of the reel 61 has a receiving groove for accommodating the traction rope, facilitating its positioning during winding. Additionally, the inner peripheral wall of the reel 61 has a fixing frame 63, which is arranged in a cross shape. The fixing frame 63 improves the overall strength of the reel 61 and facilitates its rotation.

[0060] This embodiment of a municipal pipe network drainage structure allows for the initial filtration and interception of debris in rainwater via a cover plate 2. A filter cylinder 3 further filters and intercepts debris, and a first drive assembly ejects the filter cylinder 3 from the top opening of the pipe body 1 for easy cleaning of debris inside. Additionally, a scraper 4 further filters and intercepts debris in the rainwater. Simultaneously, a second drive assembly moves the scraper 4 horizontally, allowing for rapid cleaning of sediment within the pipe body 1 during its movement.

[0061] In use, remove the cover plate 2, rotate the rotating block 54 at the bottom of the filter cylinder 3, the rotating block 54 drives the top plate 53 to rotate, causing the top plate 53 to detach from the fixed cylinder 51. The compressed spring releases its elastic force, pushing the top plate 53 upward, thereby pushing the filter cylinder 3 out from the top opening of the pipe body 1. Next, remove the filter cylinder 3 for cleaning, and then reset the top plate 53.

[0062] Then, the reel 61 is rotated, pulling the corresponding scraper 4 via the traction rope to scrape the sludge inside the pipe body 1 to the openings at both ends of the pipe body 1 for easy cleaning. Afterwards, the reel 61 is released, and the scraper 4 returns to its original position under the action of the return spring. Next, the sludge is removed from the end opening of the pipe body 1, and the filter cylinder 3 is placed inside the pipe body 1, so that the rotating block 54 and the top plate 53 engage. Finally, the cover plate 2 is placed on top. Compared to the traditional method of cleaning debris inside the pipe body using a shovel, the operation method of this embodiment is convenient, quick, and has a better cleaning effect with less labor.

[0063] The above describes the present application and its embodiments in a schematic manner, and the description is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above, without departing from the spirit of the present application, similar structural modes and embodiments can be designed without creativity, and all of them shall belong to the protection scope of the present application.
