[0028] 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.

[0029] like Figure 1 and Figure 2 As shown;

[0030] A drainage device for permeable recycled cement roads includes a drainage pipe 1, and an upper rectangular sleeve 2 is fixedly connected in an installation groove opened on the upper surface of the drainage pipe 1.

[0031] In this implementation plan: According to the public announcement (CN222295231U), a municipal road rainwater drainage device is disclosed. Although the design has the technical effects of improving the installation and dismantling efficiency of manhole cover 31 and facilitating personnel operation, the rainwater drainage device of this design has a simple structure and is insufficient in filtering impurities in the water. It is difficult to effectively intercept particulate impurities, which leads to frequent blockage of drainage pipe 1 and affects drainage efficiency. In order to solve this technical problem, a filter component 3 and a collection component 4 are added on this basis.

[0032] Furthermore:

[0033] like Figures 1 to 8 As shown:

[0034] In summary: The upper rectangular sleeve 2 has a filter assembly 3 inside, comprising two symmetrically arranged filter frames 316 inside the upper rectangular sleeve 2 and a first filter 35 fixedly connected inside the filter frames 316. The upper rectangular sleeve 2 also has a lower connecting plate 34 inside, with two rotating holes on its surface each housing a connecting shaft 315. The upper rectangular sleeve 2 also has a fixedly connected inclined plate 37 and an auxiliary rotating shaft 311 inside, with a rectangular plate 310 fitted onto the surface of the auxiliary rotating shaft 311. 0 is located below the inclined plate 37. A longitudinal rod 313 is provided above the rectangular plate 310. A U-shaped rod 314 is fixedly connected to the top of the longitudinal rod 313. A connecting shaft 315 is fixedly connected to the inside of the filter frame 316. The filter frame 316 is rotatably connected to the lower connecting plate 34 through the connecting shaft 315. Side grooves 36 are symmetrically opened on both sides of the upper rectangular sleeve 2. The side of the filter frame 316 away from the lower connecting plate 34 is located inside the side groove 36. Two symmetrically arranged side shells 319 are fixedly connected to both sides of the upper rectangular sleeve 2.

[0035] In this implementation plan: Rectangular sleeves 2 are installed at predetermined positions on both sides of the road, with the upper surface of the upper rectangular sleeve 2 flush with the ground. This design ensures the flatness of the road surface and facilitates the flow of rainwater into the upper rectangular sleeve 2. During installation, it is necessary to ensure that the connection between the upper rectangular sleeve 2 and the drainage pipe 1 is firm and well-sealed to prevent rainwater leakage and avoid damage to the road foundation structure. The position of the upper rectangular sleeve 2 needs to be accurately measured and adjusted to ensure its levelness, providing a good foundation for the subsequent installation of the filter assembly 3 and the collection assembly 4. The connecting shaft 315 is inserted into the two rotating holes of the lower connecting plate 34 and fixed inside the filter frame 316, so that the filter frame 316 can rotate relative to the lower connecting plate 34 through the connecting shaft 315. This facilitates the prevention of impurities from accumulating on the first filter screen 35 through vibration, ensuring that rainwater continuously and smoothly passes through the first filter screen 35.

[0036] Furthermore:

[0037] In an optional embodiment, a first limiting rod 312 is fixedly connected inside the upper rectangular sleeve 2, and a longitudinal rod 313 extends longitudinally through the first limiting rod 312 and the inclined plate 37. The first limiting rod 312 and the inclined plate 37 are both slidably connected to the longitudinal rod 313. A first stop shaft 38 and a second stop shaft 39 are provided below the rectangular plate 310, and the first stop shaft 38 and the second stop shaft 39 are both fixedly connected inside the upper rectangular sleeve 2.

[0038] In this implementation scheme: the first stop shaft 38 and the second stop shaft 39 inside the upper rectangular sleeve 2 restrict the rotation range of the rectangular plate 310. Rainwater flows to the rectangular plate 310 under the guidance of the inclined plate 37. Due to the action of the longitudinal rod 313 and the U-shaped rod 314, the rectangular plate 310 and the first stop shaft 38 will be in contact. When the amount of rainwater changes, the rectangular plate 310 will rotate on the auxiliary rotating shaft 311, which will drive the longitudinal rod 313 to vibrate vertically, thereby causing the U-shaped rod 314 to strike the first filter screen 35. Through the vibration, impurities are prevented from accumulating on the first filter screen 35, ensuring that rainwater continues to pass through the first filter screen 35 smoothly.

[0039] Furthermore:

[0040] In an optional embodiment, a manhole cover 31 is inserted into a cover plate groove 320 on the upper surface of the upper rectangular sleeve 2, and a lower connecting plate 34 is fixedly connected to the bottom surface of the manhole cover 31. A first arc-shaped groove 32 is formed on the upper surface of the manhole cover 31, and a second arc-shaped groove 33 connected to the first arc-shaped groove 32 is formed on the upper surface of the upper rectangular sleeve 2. The leakage hole on the surface of the manhole cover 31 is connected to the interior of the first arc-shaped groove 32.

[0041] In this implementation scheme: the manhole cover 31 is installed in the cover plate groove 320 on the upper surface of the upper rectangular sleeve 2, and the lower connecting plate 34 is fixed to the bottom surface of the manhole cover 31. The first arc-shaped groove 32 on the upper surface of the manhole cover 31 is connected to the second arc-shaped groove 33 of the upper rectangular sleeve 2. The leakage hole on the surface of the manhole cover 31 is connected to the inside of the first arc-shaped groove 32 to form a channel for rainwater to flow in. When it rains, the rainwater first enters the first arc-shaped groove 32 through the leakage hole on the surface of the manhole cover 31 which is flush with the ground, and then flows into the inside of the upper rectangular sleeve 2 through the second arc-shaped groove 33. When the rainwater entering the upper rectangular sleeve 2 flows through the first filter screen 35, the first filter screen 35 begins to filter the rainwater, intercepting impurities in the rainwater and causing the impurities to slide on the surface of the first filter screen 35.

[0042] Furthermore:

[0043] In an optional embodiment, a second limiting rod 318 is fixedly connected inside the upper rectangular sleeve 2, and inclined rods 317 are fixedly connected to both sides of the second limiting rod 318 respectively. The end of the inclined rod 317 away from the second limiting rod 318 is in contact with the first filter screen 35.

[0044] In this embodiment: one end of the inclined rod 317 of the second limiting rod 318 is attached to the first filter screen 35, which helps the first filter screen 35 to unfold and be inserted into the side groove 36 during installation.

[0045] Furthermore:

[0046] In an optional embodiment, collection components 4 are provided on both sides of the upper rectangular sleeve 2. The collection components 4 include a collection box 41, a second filter screen 42, and a support plate 49. The collection boxes 41 are respectively provided on both sides of the upper rectangular sleeve 2 and are inserted into the inside of the side housing 319. The second filter screen 42 is fixedly connected to the inside of the collection box 41. The upper rectangular sleeve 2 has a lower through groove 43 on both sides. The support plate 49 is fixedly connected to the bottom surface of the collection box 41. The surface of the collection box 41 has an upper through groove 44 that communicates with the inside of the side groove 36. The collection components 4 also include a hollow plate 46 and a positioning plate 47. The upper rectangular sleeve 2 has transfer grooves 410 on both sides that are connected to the inside of the cover plate groove 320. Each transfer groove 410 has a hollow plate 46 inserted inside. The hollow plate 46 has a spring 48 and a positioning plate 47 inside. The positioning plate 47 is fixedly connected to the upper rectangular sleeve 2. The two ends of the spring 48 are fixedly connected to the positioning plate 47 and the hollow plate 46 respectively. The hollow plate 46 is inserted into the positioning slot 45 opened on the surface of the collection box 41. The side of the hollow plate 46 away from the collection box 41 is in contact with the manhole cover 31. The side of the hollow plate 46 near the manhole cover 31 has an inclined cut surface 411.

[0047] In this implementation scheme: impurities intercepted by the first filter screen 35 enter the side channel 36 under the push of gravity and water flow. Since the side channel 36 is connected to the upper channel 44 of the collection box 41, the impurities will enter the collection box 41 along the upper channel 44. In the collection box 41, under the action of the second filter screen 42, some of the liquid flows back into the upper rectangular sleeve 2 through the lower channel 43, avoiding excessive water residue in the impurities and facilitating subsequent impurity cleaning work.

[0048] Working principle: Before road construction, according to design requirements, drainage pipe 1 is buried underground to ensure that its laying path conforms to the road drainage planning layout. Drainage pipe 1 should have a good slope to facilitate the smooth discharge of rainwater, and its material should have a certain strength and corrosion resistance to ensure long-term performance. Rectangular sleeves 2 are installed at predetermined positions on both sides of the road, so that the upper surface of the upper rectangular sleeve 2 is flush with the ground. This design ensures the flatness of the road surface and facilitates the flow of rainwater into the upper rectangular sleeve 2. During installation, it is necessary to ensure that the connection between the upper rectangular sleeve 2 and the drainage pipe 1 is firm and well sealed to prevent rainwater leakage and avoid damage to the road foundation structure. The position of the upper rectangular sleeve 2 needs to be accurately measured and adjusted to ensure its levelness, providing a good foundation for the subsequent installation of filter assembly 3 and collection assembly 4. Connecting shaft 315 is inserted into the two rotating holes of the lower connecting plate 34 and the connecting shaft 315 is fixed inside the filter frame 316, so that the filter frame 316 can rotate relative to the lower connecting plate 34 through the connecting shaft 315.

[0049] One end of the inclined rod 317 of the second limiting rod 318 is attached to the first filter screen 35, which helps the first filter screen 35 to unfold and be inserted into the side groove 36 during installation.

[0050] The manhole cover 31 is installed in the cover plate groove 320 on the upper surface of the upper rectangular sleeve 2, and the lower connecting plate 34 is fixed to the bottom surface of the manhole cover 31. The first arc groove 32 on the upper surface of the manhole cover 31 is connected to the second arc groove 33 of the upper rectangular sleeve 2. The leakage hole on the surface of the manhole cover 31 is connected to the inside of the first arc groove 32 to form a channel for rainwater to flow in.

[0051] During rainfall, rainwater first enters the first arc-shaped groove 32 through the holes on the surface of the manhole cover 31, which is flush with the ground, and then flows into the upper rectangular sleeve 2 through the second arc-shaped groove 33. As the rainwater flows through the first filter screen 35, the first filter screen 35 begins to filter the rainwater, intercepting impurities and causing them to slide on the surface of the first filter screen 35. The filtered rainwater continues to flow downwards. The first and second baffles 38 and 39 inside the upper rectangular sleeve 2 restrict the rotation range of the rectangular plate 310. Water flows towards the rectangular plate 310 under the guidance of the inclined plate 37. Due to the action of the longitudinal rod 313 and the U-shaped rod 314, the rectangular plate 310 and the first baffle 38 will be in contact. When the amount of rainwater changes, the rectangular plate 310 will rotate on the auxiliary rotating shaft 311, which will drive the longitudinal rod 313 to vibrate vertically, thereby causing the U-shaped rod 314 to strike the first filter screen 35. Through the vibration, impurities are prevented from accumulating on the first filter screen 35, ensuring that rainwater continues to pass smoothly through the first filter screen 35.

[0052] Impurities intercepted by the first filter screen 35 are pushed into the side channel 36 by gravity and water flow. Since the side channel 36 is connected to the upper channel 44 of the collection box 41, the impurities will enter the collection box 41 along the upper channel 44. In the collection box 41, under the action of the second filter screen 42, some of the liquid flows back into the upper rectangular sleeve 2 through the lower channel 43, avoiding excessive water residue in the impurities and facilitating subsequent impurity cleaning work.

[0053] When it is necessary to clean the impurities in the collection box 41, by pulling the manhole cover 31 upward, the hollow plate 46 will slide out from the positioning slot 45 under the elastic force of the spring 48, so that the collection box 41 can be taken out from the side housing 319, and the impurities in the collection box 41 can be poured out from the upper through groove 44 inside. After pouring out, the impurities can be further processed or cleaned. The collection box 41 is reinserted into the side housing 319, and the manhole cover 31 is inserted into the cover plate groove 320. The manhole cover 31 squeezes the hollow plate 46, and under the action of the inclined cut surface 411, the hollow plate 46 is inserted into the positioning slot 45 to ensure the normal operation of the device.

[0054] This permeable recycled cement road drainage device can effectively collect and treat road rainwater. The upper rectangular sleeve 2 is flush with the ground to achieve efficient rainwater collection. The filter component 3 and the collection component 4 effectively treat rainwater and impurities. It is easy to operate during maintenance and ensures long-term stable operation of the drainage device, providing a good guarantee for road drainage.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
