Description

Technical Field

[0001] This utility model belongs to the field of urban road construction technology, specifically relating to a device for preventing clogging of rainwater side wells. Background Technology

[0002] With the rapid advancement of urbanization, the area of ​​paved urban roads is constantly expanding, and the stormwater runoff coefficient is significantly increasing, placing higher demands on the smoothness of road drainage systems. As a key node for road stormwater drainage, side manholes play an important role in quickly collecting rainwater from the road surface and preventing water accumulation. Their smoothness directly affects road traffic safety and the effectiveness of urban flood control.

[0003] However, traditional storm drains only have one grate, and in practice, clogging is a common problem. Debris such as mud, fallen leaves, and household waste carried by road runoff easily accumulates at the drain inlet and inside the drain shaft, gradually reducing the cross-sectional area for water flow and even completely blocking the drainage channel. Clogging not only obstructs rainwater drainage, causing road flooding and affecting the safety of vehicles and pedestrians, but also increases the frequency and cost of manual dredging, and frequent dredging can cause secondary damage to the road structure. Especially during extreme weather events such as heavy rain, clogged storm drains cannot drain floodwater in a timely manner, potentially exacerbating the risk of urban flooding and posing a serious threat to the normal operation of the city and residents' lives.

[0004] Therefore, developing an efficient, durable, and easy-to-maintain anti-clogging device based on the causes and characteristics of rainwater well blockage is of great practical significance and application value for improving the reliability of urban drainage systems and reducing the risk of urban flooding.

[0019] like Figure 1-3 As shown, a device for preventing clogging of a rainwater side well 1 includes a rainwater side well 1, a grate seat 2 covering the opening of the rainwater side well 1, a well cylinder 3 located at the lower end of the rainwater side well 1, and a hanging basket 4 detachably installed inside the rainwater side well 1 and located between the grate seat 2 and the well cylinder 3, wherein the lower projection of the water passage holes provided on the grate seat 2 can fall entirely into the hanging basket 4.

[0020] The hanging basket 4 is made of stainless steel and includes a base plate 41, a frame 42, and a handle 43. The frame 42 is a frame structure with openings at the top and bottom, formed by side panels surrounding the base plate 41. The base plate 41 is movably installed at the bottom of the frame 42 to open or close the lower opening of the frame 42. Specifically, the base plate 41 can be rotatably installed at the lower end of one side panel of the frame 42 via a connecting shaft 45, or the base plate 41 can be slidably inserted into slots provided on the inner walls of the lower ends of two opposite side panels of the frame 42. The base plate 41 and the frame 42 are evenly distributed with a number of filter holes; the filter holes on the base plate 41 are uniformly distributed circular filter holes 411, and the filter holes on the frame 42 are arranged in a multi-level manner, with the size of the filter holes gradually increasing from bottom to top. The water filter holes on the frame 42 include at least a first-stage water filter hole 421 located at the lower end of the frame 42 and a second-stage water filter hole 422 located in the middle of the frame 42, wherein the first-stage water filter hole 421 is smaller than the second-stage water filter hole 422.

[0021] Preferably, a bracket 11 is provided on the upper side wall of the rainwater side well 1, and a hook 423 is provided on the upper edge of the hanging basket 4. The hanging basket 4 is hung on the bracket 11 via the hook 423. Preferably, the bracket 11 is an L-shaped steel, with one end pre-embedded inside the side wall of the rainwater side well 1, and the hook 423 is formed by bending the upper edge of the frame 42 of the hanging basket 4 outward. A handle 43 is installed on the top of the hanging basket 4, with both ends of the handle 43 connected to the long side of the hanging basket 4. The handle can adopt a chain structure or other structures, which are common in the prior art and are conventional structures, and will not be described in detail in this embodiment.

[0022] This invention features a detachable hanging basket installed between the grate and the manhole of a rainwater drain. The basket's bottom plate and frame are equipped with numerous filter holes. The bottom plate is movably mounted on the bottom of the frame, allowing the lower opening of the frame to be opened or closed. This allows the basket to pre-intercept and collect sewage entering the rainwater drain, reducing pollutants entering downstream pipes. This solves the problem of easy clogging in existing rainwater drains, reduces the difficulty of dredging, and lowers maintenance costs. The detachable stainless steel hanging basket design eliminates the need for maintenance personnel to enter the drain or use complex tools. They can simply open the rainwater grate, remove the basket, and empty the internal debris to complete the cleaning process, significantly shortening the dredging time and reducing manual labor intensity. Example 2

[0023] like Figure 3-6 As shown, in this embodiment, the hanging basket 4 is further provided with a partition 44. The partition 44 is a porous mesh plate structure or grid structure with a plurality of mesh holes evenly distributed thereon, and its mesh holes are larger than the circular filter holes 411, but not larger than the second-stage filter holes 422. Specifically, the first-stage filter holes 421 and the second-stage filter holes 422 are both waist-shaped holes arranged vertically (i.e., in the height direction of the surrounding plates that make up the frame 42), and the width of the first-stage filter holes 421 is the same as the diameter of the circular filter holes 411 on the bottom plate 41, and smaller than the width of the second-stage filter holes 422. The mesh holes of the partition 44 are round or square holes, and their diameter or width is larger than the diameter of the circular filter holes 411, but not larger than the width of the second-stage filter holes 422. The partition 44 is provided with multiple protruding posts 441 around its perimeter. The width of the protruding posts 441 is slightly smaller than the width of the second-stage filter holes 422. The partition 44 is supported within the frame 42 by the protruding posts 441 inserted into the second-stage filter holes 422, and its perimeter is in close contact with the inner wall of the frame 42. The protruding posts 441 are straight posts extending outward along the plane of the partition 44 or hook-shaped posts formed by bending obliquely upward and outward.

[0024] This invention utilizes a partition within the hanging basket to create a double-layer structure, facilitating tiered debris interception and enabling refined management. The double-layer design visually displays the types of debris intercepted (such as fallen leaves, plastic waste, and silt), helping management departments analyze surrounding pollution sources (such as nearby construction sites and catering areas) and providing a basis for targeted remediation (such as increasing road sweeping frequency and strengthening garbage sorting promotion). Furthermore, by observing the amount of debris accumulated in the two layers of the hanging basket, the risk of blockage in the manholes can be quickly assessed, facilitating the development of precise dredging plans and avoiding problems of "blind dredging" or "untimely dredging." Example 3

[0025] like Figure 4 , 5As shown in Figure 7, in this embodiment, the base plate 41 is installed at the lower end of a panel of the frame 42 in a rotatable manner. Specifically, a rotating seat is installed on the lower surface of the base plate 41 at one long side, and a connecting shaft 45 passes through it. The base plate 41 is rotatably connected to the connecting shaft 45 through the rotating seat, and both ends of the connecting shaft 45 are fixedly installed at the bottom of one side of the frame 42. A socket plate is installed on the two short side walls of the base plate 41 at the end away from the connecting shaft 45. The socket plate is provided with a pin hole 412. A through hole 424 is provided at the bottom of the frame 42 corresponding to the position of the pin hole 412. The base plate 41 is limited and fixed to the frame 42 by a pin 46 inserted into the pin hole 412 and the through hole 424, thus closing the lower opening of the frame 42. Preferably, each socket plate is provided with two parallel pin holes 412, and two through holes are also provided on both sides of the frame 42. The pin 46 is a U-shaped pin with an arc-shaped protrusion 461 in the middle. The gap formed between the arc-shaped protrusion 461 after the pin 46 is inserted and the bottom outer wall of the hanging basket 4 can be used as the point of force to pull out the pin 46. More preferably, in order to prevent the pin 46 from being placed randomly during sludge removal, a wire or rope-like object (not shown in the figure) is attached to the arc-shaped protrusion of the pin 46, and the other end of the wire or rope-like object can be tied to the frame 42 through the water filter hole.

[0026] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
