Description

Technical Field

[0001] This invention relates to the field of manhole covers, and more particularly to a clog-resistant sewer drainage manhole cover. Background Technology

[0002] The drainage manhole covers on both sides of the road play an important role in flood control during the rainy season. During rainfall, rainwater mixed with mud, sand, fallen leaves and other debris flows into the sewer through the drainage channels of the manhole covers. As vehicles drive over it and pedestrians trample it, the mud and sand in the drainage channels continue to accumulate and compact, forming stubborn blockages. In order to ensure the smooth flow of the drainage system, staff need to frequently carry out manual cleaning operations, which not only consumes a lot of manpower, but also makes it more difficult to clean the stubborn blockages formed in the drainage channels, making it difficult to meet the needs of timely flood control.

[0003] In summary, this application proposes an anti-clogging sewer drain cover to improve the aforementioned technical problems. Summary of the Invention

[0004] To overcome the shortcomings of existing manhole covers, which require frequent manual cleaning to ensure unobstructed drainage, resulting in high labor costs and stubborn blockages at the drainage outlets that increase the difficulty of manual cleaning and make it difficult to meet the needs of timely flood drainage, this invention provides a blockage-resistant sewer drainage manhole cover.

[0005] The technical solution of the present invention is: a clog-resistant sewer drain cover, comprising a fixed frame, a drain cover, and a filter hopper; the drain cover is installed on the fixed frame; a filter hopper for collecting garbage is detachably connected to the fixed frame; the filter hopper is provided with several filter grooves; it also includes a lever plate, gears, racks, and a linkage assembly; several lever plates for preventing blockage of the drain groove openings are rotatably connected to the drain cover, the lever plates are evenly distributed on the drain cover to form several drain groove openings; each lever plate is provided with a connecting rod; several gears are fixedly connected to each connecting rod; a linkage assembly for driving the lever plate to rotate is installed on the fixed frame; several racks are installed on the linkage assembly, and each rack meshes with an adjacent gear.

[0006] More preferably, in the above-mentioned anti-clogging sewer drain cover, the linkage component includes a fixed plate, an elastic element, a support block, and a connecting plate; several fixed plates are fixedly connected to the fixed frame; several elastic elements are fixedly connected to each fixed plate; the telescopic ends of the elastic elements on the same fixed plate are jointly fixedly connected to the support block; a connecting plate is provided on the fixed frame, and each rack is fixedly connected to the connecting plate.

[0007] More preferably, the aforementioned anti-clogging sewer drain cover also includes a slider; several connecting parts are fixedly connected to the cover; each connecting part passes through all the levers; several sliding grooves are provided on the cover; each lever can slide on the connecting part and in the sliding groove; several sliders are slidably connected to the fixed frame, and each connecting plate is fixedly connected to the adjacent slider.

[0008] More preferably, the aforementioned anti-clogging sewer drain cover also includes limit strips; each connecting plate is fixedly equipped with several limit strips for restricting the horizontal movement of the lever and gear.

[0009] More preferably, the aforementioned anti-clogging sewer drain cover also includes connecting ropes; several connecting ropes are fixed between every two adjacent levers.

[0010] More preferably, in the above-mentioned anti-clogging sewer drain cover, a sealing plate for blocking mud and sand is fixedly connected to the side of the cover adjacent to the rack, and the sealing plate is in sealed sliding contact with the side wall of the fixed frame.

[0011] More preferably, the aforementioned anti-clogging sewer drain cover also includes guide strips; several guide strips are fixed to the fixed frame, and each guide strip is located above the chute.

[0012] More preferably, the connecting rope in the aforementioned anti-clogging sewer drain cover is made of a corrosion-resistant material.

[0013] More preferably, the aforementioned anti-clogging sewer drain cover also includes a gripping block; several gripping blocks are slidably connected to the filter bucket via round rods, each round rod is not allowed to slide off the filter bucket, and each gripping block is attached to the upper side of the adjacent support block.

[0014] More preferably, the aforementioned anti-clogging sewer drain cover also includes a baffle; the fixed frame is provided with two limiting grooves; the telescopic ends of all the elastic elements on the left are jointly fixed to a baffle for blocking water flow, and the telescopic ends of all the elastic elements on the right are also jointly fixed to a baffle for blocking water flow; the baffle can slide up and down in adjacent limiting grooves, and both the baffle and the limiting groove are L-shaped.

[0015] The beneficial effects of this invention are: during the process of vehicle running over and pedestrian trampling, the manhole cover moves up and down repeatedly under the action of the elastic element, and the gear drives the rotating plate to dynamically open and close the drainage channel formed between adjacent plates, loosening the mud and sand impurities accumulated in the drainage channel, thereby minimizing the compaction of mud and sand in the drainage channel and preventing the formation of stubborn blockages, thus reducing the difficulty of cleaning for workers. At the same time, it eliminates the need for workers to frequently unclog the drainage channel of the manhole cover, greatly reducing labor costs.

[0016] By pushing the slider, the gear and rack are no longer meshed, thus releasing the rack from limiting the gear and the lever. This makes it easier to manually push the lever towards the center of the manhole cover, creating a larger drainage outlet on the left and right sides of the manhole cover. This allows the water to directly carry the garbage into the filter bucket, thereby improving drainage efficiency.

[0017] The left side of the gear is blocked and limited by the limiting strip, so as to prevent the lever from shifting, which would prevent the gear and rack from meshing properly and affect the drainage process of the drain trough.

[0018] By using baffles to block sewage around the well opening, sewage is prevented from carrying garbage into the sewer, thus improving the effectiveness of garbage interception. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] A type of anti-clogging sewer drain cover, such as Figures 1-8 As shown, it includes a fixed frame 1, a manhole cover 2, and a filter hopper 401; the manhole cover 2 is installed on the fixed frame 1; the filter hopper 401 is detachably connected to the fixed frame 1; the filter hopper 401 is provided with several filter grooves.

[0034] It also includes a lever plate 3, a gear 4, a rack 5, and a linkage assembly; several lever plates 3 are rotatably connected to the manhole cover 2, and the lever plates 3 are evenly distributed on the manhole cover 2 to form several drainage slots; each lever plate 3 is provided with a connecting rod 3001; two front-to-back symmetrical gears 4 are fixedly connected to each connecting rod 3001; a linkage assembly is installed on the fixed frame 1; several racks 5 are installed on the linkage assembly, and each rack 5 meshes with the adjacent gear 4.

[0035] The linkage assembly includes a fixed plate 101, an elastic element 102, a support block 103, and a connecting plate 104; two left-right symmetrical fixed plates 101 are fixedly connected to the fixed frame 1; two front-back symmetrical elastic elements 102 are fixedly connected to each fixed plate 101, and the elastic elements 102 are spring telescopic rods; the telescopic ends of the elastic elements 102 on the same fixed plate 101 are jointly fixedly connected to the support block 103; a connecting plate 104 is provided on the fixed frame 1, and each rack 5 is fixedly connected to the connecting plate 104.

[0036] It also includes a slider 201; two symmetrical connecting parts 2001 are fixedly connected to the manhole cover 2; each connecting part 2001 passes through all the levers 3; two symmetrical sliding grooves 2002 are provided on the manhole cover 2; each lever 3 can slide on the connecting part 2001 and in the sliding groove 2002; four sliders 201 are slidably connected to the fixed frame 1, and each connecting plate 104 is fixedly connected to the adjacent slider 201.

[0037] It also includes limit strips 202; several limit strips 202 are fixedly connected to each connecting plate 104.

[0038] It also includes connecting ropes 203; two symmetrical connecting ropes 203 are fixed between each two adjacent levers 3.

[0039] Both the front and rear sides of the manhole cover 2 are fixed with sealing plates 2003, and the sealing plates 2003 are in sealed sliding contact with the front and rear sides of the fixed frame 1.

[0040] It also includes guide strips 301; two symmetrical guide strips 301 are fixedly attached to the fixed frame 1, and each guide strip 301 is located above the slide groove 2002.

[0041] The connecting rope 203 is made of corrosion-resistant material.

[0042] The working process of this embodiment is as follows:

[0043] In order to ensure the smooth flow of the drainage system, the existing manhole covers require frequent manual cleaning operations, which not only consumes a lot of manpower, but also makes it difficult to meet the needs of timely flood drainage due to the stubborn blockages formed at the drainage outlets.

[0044] To solve the above problems, after the manhole is excavated on the road, the fixing frame 1 is inserted into the manhole and fixed. Then, the filter hopper 401 is placed into the manhole and engaged with the fixing frame 1. Next, the manhole cover 2 is aligned with the fixing frame 1, and the left and right ends of the manhole cover 2 are slowly placed against the support block 103. At this time, the extension ends of the support block 103 and the elastic element 102 are squeezed by the manhole cover 2. The manhole cover 2, the support block 103, and the extension ends of the elastic element 102 gradually move downward until the upper surface of the manhole cover 2 is flush with the upper surface of the fixing frame 1. At this point, the weight of the manhole cover 2 is insufficient to allow the extension ends of the elastic element 102 to continue moving downward. As the manhole cover 2 moves downward, the gear 4 on the lever 3 gradually meshes precisely with the rack 5. The meshing of the gears forms a stable transmission structure. The downward movement of the manhole cover 2 drives the lever 3 to rotate until the manhole cover 2 stops moving downward. Then, the lever 3 gradually changes from its initial tilted state to a vertical state, thus realizing the installation of the manhole cover 2. After rain, the water will fall into the filter hopper 401 below through the drainage channel formed between the adjacent lever 3, and enter the sewer through the filter channel. At this time, the lever 3 intercepts larger garbage and impurities on the manhole cover 2, while smaller garbage is intercepted in the filter hopper 401.

[0045] During the use of manhole cover 2, when passing vehicles run over it or pedestrians step on it, the overall weight above support block 103 increases, causing manhole cover 2 to move support block 103 further downward. The elastic element 102 is subjected to secondary compression, resulting in secondary contraction. Simultaneously, viewed from front to back, as manhole cover 2 moves downward for the second time, gear 4 rotates counterclockwise on rack 5, driving adjacent connecting rod 3001 to rotate synchronously. This causes the lower end of the lever 3 to rotate to the right until the vehicle or pedestrian leaves manhole cover 2. The overall weight above support block 103 then returns to its initial state. At this point, under the rebound action of elastic element 102, support block 103 will move manhole cover 2 back to a position flush with the upper surface of fixed frame 1. Simultaneously, as manhole cover 2 moves upward, gear 4 will rotate clockwise on rack 5, and... The adjacent connecting rods 3001 rotate synchronously, causing the lower end of the lever 3 to rotate to the left until each lever 3 returns to its initial vertical position. Thus, when vehicles run over it or pedestrians step on it, the manhole cover 2 moves up and down repeatedly under the action of the elastic element 102, and drives the lever 3 to rotate through the gear 4, making the drainage groove formed between the adjacent lever 3 in an active state, loosening the mud and sand impurities accumulated in the drainage groove. The loosened mud and sand will fall into the filter hopper 401 below, thereby minimizing the compaction of mud and sand in the drainage groove and preventing the formation of stubborn blockages, thus reducing the difficulty of cleaning for workers. At the same time, the drainage groove can be cleared by the running of vehicles and the trampling of pedestrians, thus eliminating the need for workers to frequently clear the drainage groove of the manhole cover 2, greatly reducing labor costs.

[0046] During heavy rainfall, rainwater carries debris that accumulates on manhole cover 2, severely reducing drainage efficiency. As rainfall continues to increase, this debris rapidly accumulates on manhole cover 2, forming layers of blockage and drastically reducing drainage efficiency. To ensure the normal operation of the drainage system, workers typically lift manhole cover 2, allowing water carrying debris to fall directly onto filter hopper 401. However, due to its heavy material, manually lifting manhole cover 2 to clear debris, accelerate drainage, and subsequently reposition it is extremely inconvenient, requiring significant physical effort and posing a high safety risk. To address these issues, when workers need to remove debris from manhole cover 2, they manually push the front slider 201 forward and the rear slider 201 backward, causing each slider 201 to move the adjacent connecting plate 104. The rack 5 on the connecting plate 104 moves away from the gear 4, so that the gear 4 and the rack 5 are no longer meshed together, thereby releasing the rack 5 from limiting the gear 4 and the lever 3. Then, all the levers 3 are pushed manually, and all the levers 3 will slide on the connecting part 2001 and the slide groove 2002 with the gear 4, so that all the levers 3 move closer to the middle of the manhole cover 2, thereby forming a large drainage outlet on the left and right sides of the manhole cover 2, so that the water flow directly carries the garbage into the filter hopper 401, thereby improving the drainage efficiency. At the same time, there is no need to manually lift the heavy manhole cover 2, reducing the workload. After the drainage is completed, the levers 3 can be manually reset one by one. After the reset is completed, the slider 201 is pushed back to the initial position, so that the gear 4 and the rack 5 can re-mesh together.

[0047] Furthermore, during normal use of the manhole cover 2, after the manhole cover 2 is subjected to external pressure, in order to prevent the lever 3 from sliding on the connecting part 2001, the left side of the gear 4 is blocked and limited by the limiting strip 202, thereby preventing the lever 3 from shifting, which would cause the gear 4 and the rack 5 to be unable to mesh smoothly, thus affecting the drainage process of the drainage channel.

[0048] Furthermore, considering that during the manual resetting process of the lever 3, due to the large number of levers 3 and the difficulty for the operator to observe the specific position of the rack 5, it is difficult to quickly reset the levers 3, the following optimization is made: when the operator needs to push the lever 3 to reset the levers 3, they only need to push the leftmost and rightmost levers 3 to the side away from the center of the manhole cover 2, so that the leftmost and rightmost levers 3 move to the left and right respectively. At this time, the connecting rope 203 on the lever 3 drives the adjacent levers 3 to move together until the leftmost and rightmost levers 3 move to the leftmost and rightmost sides of the slide 2002 respectively. At this time, the connecting rope 203 is taut and each lever 3 returns to its initial position. Thus, it is not necessary to manually align and reset each one, which greatly improves the efficiency of manual work.

[0049] Furthermore, to prevent water carrying mud and sand from flowing between gear 4 and rack 5 during repeated up-and-down movement of the manhole cover 2, sealing plates 2003 are added to the front and rear sides of the manhole cover 2. This ensures that the sealing plates 2003 remain in contact with the front and rear sides of the fixed frame 1 during the up-and-down movement of the manhole cover 2, thereby preventing water carrying mud and sand from flowing between gear 4 and rack 5, causing wear on gear 4 and rack 5, and affecting the smoothness of the transmission. Simultaneously, if... Figure 5 As shown, the guide strip 301 blocks the top of the slide 2002 and guides the water flow to flow away from the slide 2002, thereby minimizing the amount of debris stuck in the slide 2002 and further improving the protection of the gear 4 and rack 5.

[0050] Example 2

[0051] Based on Example 1, such as Figures 1-3 and Figures 9-11 As shown, it also includes a gripping block 402; two symmetrical gripping blocks 402 are slidably connected to the filter hopper 401 by a round rod. Each round rod cannot slide off the filter hopper 401, and each gripping block 402 is attached to the upper side of the adjacent support block 103.

[0052] It also includes a baffle 403; the fixed frame 1 is provided with two limiting grooves 1001; the telescopic ends of all the elastic elements 102 on the left are fixedly connected to a baffle 403, and the telescopic ends of all the elastic elements 102 on the right are also fixedly connected to a baffle 403; the baffle 403 can slide up and down in the adjacent limiting grooves 1001, and both the baffle 403 and the limiting grooves 1001 are set to L-shape.

[0053] The working steps of this embodiment are as follows:

[0054] When the waste in the filter hopper 401 reaches its storage limit, the drainage efficiency of the manhole cover 2 will be greatly reduced, and may even cause water to have difficulty flowing smoothly into the sewer. A large amount of sewage will accumulate around the manhole cover 2, forming a waterlogged area. At this time, manual cleaning of the waste in the filter hopper 401 is required. However, because the sewage accumulates around the manhole cover 2, it is difficult to determine the exact location of the filter hopper 401 after lifting the manhole cover 2. Manual groping is required. If there are glass fragments in the filter hopper 401, they can easily cause cuts and pose a safety hazard. To solve the above problems, when the manhole cover is manually lifted... 2. After the elastic element 102 is lifted up so that it no longer squeezes the support block 103, the elastic element 102 will cause the support block 103 to spring back upward. At the same time, the support block 103 will cause the gripping block 402 to move upward together until the elastic element 102 is completely reset. At this time, the gripping block 402 is above the water. The operator can directly grip the gripping block 402 and lift it upward to remove the filter hopper 401 from the well. Then the garbage in the filter hopper 401 can be cleaned. Thus, there is no need for manual exploration in the sewage, avoiding scratches, which improves the convenience of operation and the cleaning efficiency.

[0055] Furthermore, as the elastic element 102 drives the support block 103 to rebound upwards, the telescopic end of the elastic element 102 will drive the baffle 403 to move upwards together, causing the baffle 403 to slide upwards from the limiting groove 1001 of the fixed frame 1, thereby blocking the area around the well opening. After the baffle 403 rises, it forms a well opening enclosure, which can block sewage from flowing in when the filter bucket 401 is manually removed, thereby preventing sewage from carrying garbage into the sewer and improving the garbage interception effect. After the filter bucket 401 is cleaned, it is slowly put back into the well opening by the operator, and then the well cover 2 is put back to the initial position. The telescopic end of the elastic element 102 is squeezed again, and the well cover 2 will return to the initial position with the support block 103, the gripping block 402 and the baffle 403.

[0056] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
