Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal drainage technology, specifically a municipal roadside drainage system for preventing blockages and draining water. Background Technology
[0002] Municipal roadside drainage systems are an important measure for urban flood control and drainage. Nowadays, a large area of urban land is occupied by roads. While ensuring the structural strength of the road surface and driving safety, urban roads have lost their original drainage capacity. Therefore, it is necessary to install rainwater grates and sewer wells on the roadside to meet the needs of both traffic and drainage.
[0003] Currently, most municipal roads are lined with greenery, and fallen leaves often remain on the ground. During rain or when water trucks wash the roads, these leaves are carried into the sewers by the running water. To prevent sewer blockage, some sewers have been fitted with filter baskets to intercept the leaves carried in by the water. Existing filter baskets are all ordinary frame structures, intercepting leaves on the bottom and sides while draining water. However, during the rainy season, the water flow increases dramatically, and the amount of leaves and debris carried in the water also surges. These leaves and debris quickly cover the bottom of the filter basket, obstructing drainage. Only the sides of the basket are left to drain, drastically reducing drainage efficiency and easily causing flooding. This severely impacts flood prevention and drainage effectiveness, necessitating immediate improvement. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a municipal roadside drainage system for preventing blockages and draining water, which solves the problem that filter baskets in existing municipal roadside drainage systems are easily clogged by fallen leaves and garbage, affecting the effectiveness of preventing blockages and draining water.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A municipal roadside drainage system for preventing blockage and drainage includes a fixed frame, a grate, a drain well, and a sewer connected to the drain well. The grate is hinged to the fixed frame. The grate includes a grate frame, a panel on the top of the grate frame, drainage channels evenly distributed on the panel, and horizontal and vertical back ribs at the bottom of the panel and located between adjacent drainage channels.
[0007] The bottom edge of the outer wall of the fixed frame is provided with an outer edge plate, and a reinforcing corner plate is provided between the outer edge plate and the outer wall of the fixed frame;
[0008] A well opening is provided at the top of the sewer corresponding to the position of the fixed frame. The length and width of the well opening are equal to the inner length and width of the fixed frame, and the length and width of the well opening are greater than the length and width of the sewer.
[0009] A stainless steel ribbed filter basket is placed inside the wellhead. A through hole is provided in the center of the bottom of the inner wall of the filter basket. A filter cylinder is vertically fixed at the position corresponding to the through hole on the bottom of the inner wall of the filter basket. A top cover is fixed on the top of the filter cylinder. A lifting handle is symmetrically fixed on the filter cylinder. A filter frame supported at the bottom of the wellhead is fixed at the bottom of the filter basket.
[0010] The bottom of the sewer well is located at a height lower than the bottom of the sewer. A sedimentation tank is placed at the bottom of the sewer well. Multiple inclined plates are fixed at equal intervals along the horizontal direction inside the sedimentation tank. A connecting rod is fixed to the top edge of the sedimentation tank. The connecting rod is fixedly connected to the top edge of the inclined plate, and the middle part of the connecting rod is bent upward to form a lifting ring.
[0011] Preferably, the drainage channel is a long strip channel and is arranged along the length direction of the grate plate, the transverse back ribs are long strips and connect the inner side wall of the grate frame and the bottom of the panel, and the longitudinal back ribs are short strips and connect the inner side wall of the grate frame, the bottom of the panel and the transverse back ribs.
[0012] Preferably, the fixed frame, outer edge plate, and reinforcing corner plate are all pre-embedded in the ground, and the top plane of the fixed frame and the grate plate is not higher than the ground.
[0013] Preferably, the filter basket and sedimentation tank are both trapezoidal bucket-shaped structures with a large top opening and a small bottom size, and the top dimensions of the filter basket and sedimentation tank are adapted to the length and width dimensions of the wellhead and the sewer well, respectively.
[0014] Preferably, the diameter of the through hole and the filter cylinder is one-third to one-third of the length of the short side of the bottom of the filter basket, and the height of the filter cylinder 502 is not less than twice the radius of the through hole 501.
[0015] Preferably, the top cover is a frustum structure that is larger at the top and smaller at the bottom.
[0016] Preferably, the filter frame is located at the bottom edge of the filter basket, and the vertical height of the filter frame is not less than 5 cm.
[0017] Preferably, the top edge of the sedimentation tank is not higher than the bottom height of the sewer.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] (1) This utility model sets a through hole in the center of the bottom of the filter basket and sets a filter cylinder and a top cover. During the drainage process from top to bottom, the water will wash the inner wall of the filter basket and the outer wall of the filter cylinder, ensuring that the inner wall of the filter basket and the outer wall of the filter cylinder will not be blocked by leaves and garbage, thus ensuring the overall drainage area. At the same time, the filter cylinder increases the drainage area from the original size of the through hole at the bottom of the filter basket to the size of the side area of the filter cylinder. The drainage area is increased instead of decreased, thus effectively ensuring drainage efficiency and achieving the effect of preventing blockage and flooding. This solves the problem that the filter basket in the existing municipal roadside drainage system is easily blocked by fallen leaves and garbage, which affects the effect of preventing blockage and flooding.
[0020] (2) This utility model places a sedimentation tank in the drain well below the filter basket. During the drainage process of the roadside drainage system, in addition to fallen leaves and garbage, the water also contains a lot of mud and sand carried by the wheels. By setting an inclined plate in the sedimentation tank, using the same principle as the inclined plate sedimentation tank, more of the mud and sand in the water is intercepted and settled in the sedimentation tank, reducing the amount of mud and sand entering the sewer. This not only reduces the frequency of sludge cleaning in the sewer, but also reduces biogas and bacteria caused by sludge, thus improving the cleanliness of the drainage system.

[0028] like Figures 1-5 As shown, this utility model provides a technical solution: a municipal roadside drainage system for preventing blockage and drainage, including a fixed frame 1, a grate 2, a drain well 3, and a sewer 4 connected to the drain well 3;
[0029] The grate 2 is hinged to the fixed frame 1. The grate 2 includes a grate frame 201, a panel 202 set on the top of the grate frame 201, drainage grooves 203 evenly arranged on the panel 202, and horizontal back ribs 204 and longitudinal back ribs 205 set at the bottom of the panel 202 and located between adjacent drainage grooves 203. The drainage grooves 203 are long grooves and are arranged along the length direction of the grate 2. The horizontal back ribs 204 are long strips and connect the inner side wall of the grate frame 201 and the bottom of the panel 202. The longitudinal back ribs 205 are short strips and connect the inner side wall of the grate frame 201, the bottom of the panel 202 and the horizontal back ribs 204. The grate 2 can be an integral cast structure or an integral welded structure. By setting the horizontal back ribs 204 and longitudinal back ribs 205, the tensile strength can be improved and the compressive strength can be enhanced.
[0030] An outer edge plate 101 is provided at the bottom edge of the outer wall of the fixed frame 1. A reinforcing corner plate 102 is provided between the outer edge plate 101 and the outer wall of the fixed frame 1 to improve the structural strength of the fixed frame 1 and prevent the outer edge plate 101 from being deformed by frequent rolling. The fixed frame 1, the outer edge plate 101 and the reinforcing corner plate 102 are all embedded in the ground and the top plane of the fixed frame 1 and the grate plate 2 is not higher than the ground.
[0031] A well opening 301 is provided at the top of the sewer well 3 corresponding to the position of the fixed frame 1. The length and width of the well opening 301 are equal to the inner length and width of the fixed frame 1, and the length and width of the well opening 301 are greater than the length and width of the sewer well 3. The height of the plane at the bottom of the sewer well 3 is less than the height of the bottom of the sewer 4.
[0032] A stainless steel ribbed filter basket 5 is placed inside the wellhead 301. A through hole 501 is provided in the center of the bottom of the inner wall of the filter basket 5. A filter cylinder 502 is vertically fixed at the bottom of the inner wall of the filter basket 5 corresponding to the position of the through hole 501. A top cover 503 is fixed on the top of the filter cylinder 502. A lifting handle 504 is symmetrically fixed on the filter cylinder 502. A filter frame 505 supported on the bottom of the wellhead 301 is fixed at the bottom of the filter basket 5.
[0033] The diameters of the through hole 501 and the filter cylinder 502 are one-third to one-third of the length of the short side of the bottom of the filter basket 5, and the height of the filter cylinder 502 is not less than twice the radius of the through hole 501, ensuring that the side area of the filter cylinder 502 is relatively large and can have a larger filtration area. The top cover 503 is a frustum structure with a larger top and a smaller bottom, which guides the water flow to the surrounding area. The filter frame 505 is located at the bottom edge of the filter basket 5, and the vertical height of the filter frame 505 is not less than 5 cm, increasing the height difference between the bottom of the filter frame 505 and the bottom of the well opening 301, and preventing the filter frame 505 from being blocked by the bottom of the well opening 301 and affecting the filtration efficiency.
[0034] A sedimentation tank 6 is placed at the bottom of the sewer well 3. The top edge of the sedimentation tank 6 is not higher than the bottom height of the sewer 4. Both the filter basket 5 and the sedimentation tank 6 are trapezoidal bucket-shaped structures with a large top opening and a small bottom size. The top dimensions of the filter basket 5 and the sedimentation tank 6 are adapted to the length and width dimensions of the well opening 301 and the sewer well 3, respectively, for easy access. Multiple inclined plates 601 are fixed at equal intervals along the horizontal direction inside the sedimentation tank 6. A connecting rod 602 is fixed to the top edge of the sedimentation tank 6. The connecting rod 602 is fixedly connected to the top edge of the inclined plate 601, and the middle part of the connecting rod 602 is bent upward to form a lifting ring 603.
[0035] Working principle:
[0036] During the drainage process of the sewer system, water flows from top to bottom. Fallen leaves and garbage mixed in the water are intercepted by the filter basket 5 and then flow to the drain well 3 below. The water washes the inner wall of the filter basket 5 and the outer wall of the filter cylinder 502, preventing leaves and garbage from adhering to the inner wall of the filter basket 5 and the outer wall of the filter cylinder 502 and thus blocking the drainage. This ensures the overall drainage area of the filter basket 5. The filter cylinder 502 increases the drainage area from the original size of the through hole 501 at the bottom of the filter basket 5 to the size of the side of the filter cylinder 502. The height of the filter cylinder 502 is not less than twice the radius of the through hole 501, thereby increasing the corresponding drainage area by at least four times. The drainage area does not decrease but increases, thus effectively ensuring drainage efficiency.
