Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically a sewer manhole cover with anti-clogging function. Background Technology

[0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, and equipment set up within the planned construction area of ​​urban areas and towns (townships) to provide paid or free public goods and services to residents based on government responsibility and obligations. Municipal sewers are channels for draining water from roads and are an important part of municipal road construction. Sewers are generally equipped with manhole covers to ensure pedestrian safety without affecting drainage. With the advancement of technology, people have increasingly higher requirements for manhole covers used in municipal engineering. On municipal streets, items dropped by pedestrians may fall into the sewers through the drainage holes of manhole covers, causing unnecessary property damage. At the same time, during rainy weather, when there is a lot of water on the road, it is difficult to open manhole covers for drainage without tools, which cannot meet the needs of today's society.

[0003] Chinese utility model patent CN218148808U discloses a pollution-proof manhole cover for municipal engineering. It features a garbage collection box that filters household waste during drainage, keeping it inside the box to prevent clogs. Multiple drainage holes around the box and at the bottom ensure proper drainage. When too much waste is collected, the weight causes a spring to contract, increasing the box's capacity. If a passerby accidentally drops a phone or key into the manhole, the cover can be opened to retrieve the item.

[0004] During use, the manhole cover has water inlets for drainage. However, since most manhole covers are located in exposed areas such as roads, the water inlets are easily clogged by garbage, affecting the drainage of accumulated water. Also, when there is a lot of water accumulation during rainy days, traffic police and other staff will open the manhole cover to facilitate the rapid drainage of water. However, once the manhole cover is opened, the sewer opening is directly exposed, posing a risk of pedestrians accidentally entering. Therefore, it requires special supervision, which is quite troublesome. In addition, with the sewer opening open, larger garbage can float into the garbage collection box and clog the drainage holes, affecting the drainage of accumulated water. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides a sewer manhole cover with anti-clogging function, which has the following beneficial effects: 1. This type of sewer cover with anti-clogging function has a vertical drainage channel on the ground, with the cover body at the top of the drainage channel and a sewage pipe below the cover body. The cover body can slide inside the sewage pipe. A first slider is fixedly connected to the bottom surface of the cover body, and a first spring allows the cover body to slide on the inner wall of the sewage pipe. At the same time, a detachable collection box is set on the ground outside the sewage pipe, and the inside of the collection box is connected to the inside of the sewage pipe. When the cover body is blocked, it can be lowered so that the upper surface of the cover body is flush with the connecting hole. This allows a large amount of rainwater to wash away the garbage on the upper surface of the cover body and bring it into the collection box, thus cleaning the upper surface of the cover body. The cover body can then be adjusted back to its original position, achieving the function of quickly cleaning the cover body.

[0016] 2. This type of sewer manhole cover with anti-clogging function has a water baffle plate installed under the cover body. The water baffle plate and the cover body are linked by a linkage mechanism, so that when the water baffle plate is adjusted up and down, it can drive the cover body to adjust up and down, thereby realizing the automatic adjustment of the cover body's up and down position and achieving the self-cleaning function of the cover body.

[0017] 3. This type of sewer cover with anti-clogging function has a linkage mechanism installed on the inner wall of the sewage pipe. When rainwater flows from the drain outlet on the cover body to the baffle plate, the baffle plate collects a certain amount of rainwater and generates a certain weight. Under the pressure of the weight, the baffle plate can press the inclined block and slide it against the inner wall of the mounting groove. While the inclined block is compressed into the mounting groove, the limiting plate can retract along with the inclined block. At the same time, the cover body and the baffle plate are connected by a connecting rod. When the baffle plate is pressed down, the cover body will also descend. A drainage groove is opened on the side of the inclined block near the baffle plate. When the baffle plate and the cover body descend, the rainwater on the baffle plate can be discharged along the drainage groove. After the rainwater is slowly discharged, the baffle plate can drive the cover body and the baffle plate back to their original position under the elastic force of the second spring, realizing the automatic cleaning of impurities on the cover body.

[0028] Example 1: This embodiment provides a sewer manhole cover with anti-clogging function, which has the following technical features.

[0029] Please see Figure 1-5A sewer manhole cover with anti-clogging function includes a ground surface 100, a vertical drainage channel formed beneath the ground surface 100, a manhole cover body 200 at the top of the drainage channel, and a through drainage outlet 210 on the manhole cover body 200. The manhole cover body 200 is characterized by a connected sewage pipe 290 below it, a first sliding groove 103 on the inner wall of the sewage pipe 290, and a first limiting rod 240 vertically fixed inside the first sliding groove 103. A first spring 230 is fitted on the side. The bottom of the first spring 230 is fixedly connected to the bottom of the first sliding groove 103. A first slider 220 is fixedly connected to the top of the first spring 230. The first slider 220 is slidably disposed on the first limiting rod 240. The first slider 220 is fixedly connected to the bottom of the manhole cover body 200. A fixing groove 101 is provided on the ground 100 outside the manhole cover body 200. A collection mechanism is provided inside the fixing groove 101 to collect the impurities accumulated on the manhole cover body 200.

[0030] Furthermore, the collection mechanism includes: a collection box 110, which is slidably disposed inside the fixing groove 101. The top plate of the collection box 110 has symmetrical lifting holes 111. The side of the collection box 110 near the drain pipe 290 has a connecting hole 112, which connects the collection box 110 and the drain pipe 290.

[0031] Furthermore, a second sliding groove 104 is provided on the inner wall of the sewage pipe 290. A second limiting rod 280 is vertically fixed inside the second sliding groove 104. A second slider 260 is slidably fitted on the second limiting rod 280. One end of a second spring 270 is fixedly connected to the bottom of the second slider 260. The other end of the second slider 260 is fixedly connected to the bottom of the second sliding groove 104. The second spring 270 is fitted on the outside of the second limiting rod 280. The two second sliders 260 are respectively fixedly connected to both ends of the baffle plate 250. A linkage mechanism is provided between the baffle plate 250 and the manhole cover body 200.

[0032] Further, the linkage mechanisms include: The mounting groove 310 is located on the inner wall of the drain pipe 290; The third limiting rod 320 is set perpendicularly to the drain pipe 290 inside the mounting groove 310; The third spring 330 is fitted onto the outside of the third limiting rod 320; The upright plate 340 is slidably fitted inside the mounting groove 310, and the two ends of the third spring 330 are respectively fixedly connected to the inner wall of the mounting groove 310 and one side of the upright plate 340. The limiting plate 350 is fixedly connected to the upright plate 340, and the limiting plate 350 is located below the manhole cover body 200; The inclined top block 360 is fixedly connected to the vertical plate 340, and the inclined top block 360 is located below the water baffle 250.

[0033] Furthermore, the top of the inclined top block 360 near the water baffle 250 is set as an inclined surface, the height of the inclined top block 360 is higher than the height of the water baffle 250, and a stop block is fixedly set at the bottom of the inclined top block 360.

[0034] It should be noted that when the baffle plate 250 slides from the inclined surface of the inclined top block 360 to the plane of the inclined top block 360, the limiting block has been received inside the mounting groove 310, which facilitates the descent of the manhole cover body 200. After the baffle plate 250 returns to its original position, the manhole cover body 200 rises to its original position first, and at the same time, the limiting plate 350 is pushed out from inside the mounting groove 310, and the outer edge of the baffle plate extends beyond the outer edge of the inclined top block 360, which can prevent the baffle plate 250 from sliding off the inclined top block 360.

[0035] Furthermore, a drainage groove 361 is provided on the side of the inclined top block 360 near the water baffle 250, and the drainage groove 361 is located below the inclined surface of the inclined top block 360.

[0036] It should be noted that the depth of the drainage channel 361 extends to the bottom of the inclined top block 360 and the baffle (not shown in the figure), which facilitates the drainage of water accumulated on the baffle plate 250.

[0037] Furthermore, a seepage groove 102 is provided on the side wall where the drain pipe 290 contacts the collection box 110, and the seepage groove 102 connects the interior of the collection box 110 and the interior of the drain pipe 290.

[0038] It should be noted that the drain trough is located below the second sliding groove 104, which can prevent the water accumulated inside the collection box 110 from draining onto the baffle plate 250.

[0039] Furthermore, the manhole cover body 200 and the water baffle 250 are connected by a connecting rod 120.

[0040] Working principle: A through-drainage channel is provided on the ground 100, and a manhole cover body 200 is installed on the top of the drainage channel. A sewage pipe 290 is installed inside the drainage channel. Rainwater flows from the drain outlet 210 to the top of the baffle plate 250. When the rainwater reaches a certain amount, the baffle plate 250 becomes heavier, thus pressing the inclined top block 360 to slide into the installation groove 310. This causes the upright plate 340 to slide against the upright plate 340 into the installation groove 310. At this time, the limiting plate 350 slides into the installation groove 310 along with the upright plate 340. When the manhole cover 200 reaches the plane of the inclined block 360, the limiting plate 350 is retracted into the mounting groove 310, thereby causing the manhole cover body 200 to be lowered by the connecting rod 120 towards the drain pipe 290. At this time, the upper surface of the manhole cover body 200 drops to the position of the connecting hole 112. When a large amount of rainwater is discharged, the rainwater can carry the garbage on the upper surface of the manhole cover body 200 through the connecting hole 112 into the interior of the collection box 110. At this time, the interior of the collection box 110 contains a mixture of rainwater and impurities. A through-hole is opened on the side of the collection box 110 near the drain pipe 290. A seepage channel 102 is provided, which connects to the inside of the drain pipe 290. This allows rainwater from the impurities to be discharged into the drain pipe 290. When the collection box 110 is full, it can be easily lifted out through the lifting hole 111, facilitating the unified disposal of impurities. A drain channel 361 is provided on the side of the inclined top block 360 near the baffle plate 250. When the baffle plate 250 is on the block, the water accumulated on the baffle plate 250 can flow into the drain pipe 290 below through the drain channel 361, thereby reducing the water accumulation on the baffle plate 250. As the water level gradually decreases, the baffle plate 250 can slowly slide upwards. After the baffle plate 250 returns to its original position, the manhole cover body 200 rises along with the baffle plate 250. At this time, the inclined top block 360 can return to its original position under the thrust of the third spring 330, and the limiting plate 350 can return to its original position to support the manhole cover body 200 and prevent the manhole cover body 200 from sinking due to external gravity. Only when there is enough water on the baffle plate 250 can the manhole cover body 200 descend to automatically clean the impurities on the manhole cover body 200 and automatically restore it.

[0041] In summary, this type of sewer cover with anti-clogging function has a vertical drainage channel on the ground 100, a cover body 200 at the top of the drainage channel, and a drain pipe 290 below the cover body 200. The cover body 200 can slide inside the drain pipe 290. A first slider 220 is fixedly connected to the bottom surface of the cover body 200, and a first spring 230 allows the cover body 200 to slide on the inner wall of the drain pipe 290. Meanwhile, on the ground 100 outside the drain pipe 290... A detachable collection box 110 is provided on the top, and the interior of the collection box 110 is connected to the interior of the sewage pipe 290. When the manhole cover body 200 is blocked, the manhole cover body 200 can be lowered so that the upper surface of the manhole cover body 200 is flush with the connecting hole 112. In this way, a large amount of rainwater can wash away the garbage on the upper surface of the manhole cover body 200 and bring it into the interior of the collection box 110, so that the upper surface of the manhole cover body 200 can be cleaned. Then the manhole cover body 200 can be adjusted back to its original position, realizing the function of quickly cleaning the manhole cover body 200.

[0042] In summary, this type of sewer cover with anti-clogging function has a water baffle 250 installed below the cover body 200. The water baffle 250 and the cover body 200 are linked by a linkage mechanism, so that when the water baffle 250 is adjusted up and down, it can drive the cover body 200 to adjust its height up and down, thereby realizing the automatic adjustment of the cover body 200's position and achieving the self-cleaning function of the cover body 200.

[0043] In summary, this type of sewer cover with anti-clogging function, through the linkage mechanism set on the inner wall of the sewage pipe 290, allows rainwater to flow along the drain outlet 210 on the cover body 200 to the baffle plate 250. After collecting a certain amount of rainwater, the baffle plate 250 generates a certain weight. Under the pressure of this weight, the baffle plate 250 can press the inclined block 360 to slide against the inner wall of the mounting groove 310. While the inclined block 360 is compressed into the mounting groove 310, the limiting plate 350 can retract along with the inclined block 360. At the same time, the baffle plate 250... The manhole cover body 200 is connected to the baffle plate 250 by a connecting rod 120. When the baffle plate 250 is pressed down, the manhole cover body 200 will also descend. A drainage groove 361 is provided on the side of the inclined top block 360 near the baffle plate 250. When the baffle plate 250 and the manhole cover body 200 descend, the rainwater on the baffle plate 250 can be discharged along the drainage groove 361. After the rainwater is slowly discharged, the baffle plate 250 can be driven to return the manhole cover body 200 and the baffle plate 250 to their original positions under the elastic force of the second spring 270, realizing the automatic cleaning of impurities on the manhole cover body 200.
