Description

Technical Field

[0001] This invention relates to the field of municipal infrastructure technology, and in particular to a municipal flood control device. Background Technology

[0002] Urban road drainage systems are one of the key infrastructures ensuring the normal operation of cities. Among them, drainage manhole covers, as the entry point for rainwater from the road surface into the underground pipe network, directly affect the efficiency of the entire system. Currently, the drainage manhole covers widely used on roads typically have parallel strip-shaped drainage slots cut into the cover body. While this structure is simple, it has revealed significant shortcomings in practical use.

[0003] First, on sunny days or at the beginning of rainfall, fine particles such as silt and gravel on the road surface are easily deposited in these narrow gaps by wind or small amounts of water, gradually accumulating and hardening, leading to blockage. Second, under the influence of wind or water flow, larger debris such as branches, fallen leaves, and plastic bags often get stuck in the gaps. These blockages severely reduce the effective drainage area of ​​the drainage manhole covers, significantly decreasing their drainage capacity. Especially during the rainy season and other periods of heavy rainfall, rainwater cannot be drained into the underground pipe network in time through the blocked manhole covers, easily causing road flooding, affecting traffic, and in severe cases, even causing urban flooding and other disasters. Currently, cleaning manhole covers mainly relies on regular manual dredging, which not only consumes a lot of manpower and resources but also has a slow response time and is difficult to cope with sudden rainstorms.

[0004] Therefore, the existing structural design of drainage manhole covers is significantly inadequate in preventing debris blockage and ensuring smooth drainage under extreme weather conditions. There is an urgent need to provide a flood-proof manhole cover that can automatically clear blockages and maintain efficient drainage capacity over a long period of time to solve the above problems. Summary of the Invention

[0005] This invention aims to solve the technical problem that existing drainage well covers are easily blocked by debris, leading to poor drainage and the risk of urban flooding. It provides a municipal flood control device with a novel structure that can use the energy of rainwater to automatically clear silt and ensure that drainage channels are unobstructed at all times.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A municipal flood control device includes a manhole cover body, wherein the manhole cover body is provided with a grid structure for drainage; A dredging component, which is movably disposed below the grid structure, is used to remove blockages within the grid structure; A drive component is connected to the dredging component for driving. The drive component is used to collect the drainage flowing through the grid structure and to drive the dredging component to move back and forth using the gravitational potential energy of the drainage.

[0007] Preferably, the drive assembly includes a water collection container located below the drainage path for receiving and containing drainage. An elastic reset member is connected to the water collection container and is used to provide elastic potential energy when the weight of the water collection container changes, so that the water collection container can move up and down.

[0008] Preferably, the drive assembly further includes a valve-controlled drainage mechanism, which is linked to the water collection container; When the water collection container descends to a preset position due to the increased weight of the accumulated water, the valve-controlled drainage mechanism opens to drain the water from the water collection container.

[0009] Preferably, the valve-controlled drainage mechanism includes: A fixed first tapered rod; A hollow extension located inside the water collection container is sleeved on the guide rod of the first conical rod, and at least one drainage hole is provided at the bottom of the hollow extension. When the water collection container descends, the hollow extension moves toward the narrow end of the first conical rod, so that the drainage through hole and the conical surface of the first conical rod form a drainage gap.

[0010] Preferably, the dredging component includes at least one scraper, the blade of which engages with the gaps in the grid structure and reciprocates along the length of the gaps.

[0011] Preferably, the dredging component and the water collection container are connected by a linkage mechanism, and the lifting motion of the water collection container is converted into the reciprocating linear motion of the dredging component through the linkage mechanism.

[0012] Preferably, the manhole cover body includes an outer frame and an inner frame, and a sandwich channel for collecting rainwater is formed between the outer frame and the inner frame. The bottom of the sandwich channel is provided with a drainage outlet that communicates with the drive assembly.

[0013] Preferably, the elastic reset element is a tension spring, with one end of the tension spring fixed and the other end connected to the water collection container.

[0014] Preferably, a second conical rod is coaxially disposed below the first conical rod, with the wide end of the second conical rod facing the first conical rod, for limiting the descent stroke of the water collection container.

[0015] Preferably, the manhole cover body is provided with a guide rail for guiding the movement of the scraper, and both ends of the scraper extend and slide within the guide rail.

[0016] The beneficial effects of this invention are: 1. This invention designs a dredging component driven by the gravitational potential energy of rainwater. During rainfall, the device can automatically and repeatedly clean the gaps in the grid, pushing away the blocked mud, sand, leaves and other debris, without the need for external energy or manual operation.

[0017] 2. Through continuous automatic dredging, this device can always maintain the grid structure with the maximum effective drainage area, ensuring that rainwater can be quickly discharged into the underground pipe network under extreme weather conditions such as heavy rain, which greatly reduces the risk of road flooding and urban waterlogging.

[0018] 3. The energy for the entire dredging process comes from the collected rainwater. It is a passive, self-powered system that does not consume any electricity or other fossil fuels, which is in line with the design concept of green and sustainable development. Attached Figure Description

[0020] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Example 1 This embodiment presents a municipal flood control device; please refer to [link / reference]. Figures 1-5 Its core structure is the manhole cover body. The manhole cover body includes a fixed outer frame 1 and an inner frame 11 located inside the outer frame 1. A sandwich layer 100 with a solid bottom is formed between the outer frame 1 and the inner frame 11. Several parallel grid strips 12 are arranged in an array along the width direction inside the inner frame 11, and strip-shaped gaps for drainage are formed between adjacent grid strips 12. The direction of these gaps is parallel to the length direction of the inner frame 11.

[0024] To effectively collect and guide water flow, a specific location of the interlayer 100, preferably at the center of the inner frame 11 in the width direction, is provided with an outwardly extending interlayer extension 200 that communicates with the interlayer 100. In this way, rainwater will fall into and collect in the channel area formed by the interlayer 100 and the interlayer extension 200.

[0025] At the bottom of the interlayer extension 200, a pipe connector 2 is provided, which is connected to the aforementioned channel area. The pipe connector 2 is connected to a pipe 3 with its outlet facing downward, for directing the collected water to the drive assembly.

[0026] The core of this embodiment lies in an automatic dredging system driven by rainwater, which includes a dredging component and a drive component.

[0027] The dredging component is located below the grid bars 12. Specifically, a scraper 13 is positioned below the grid bars 12 along the width direction of the inner frame 11. The blade of the scraper 13 extends upward and fits tightly into the gaps formed by adjacent grid bars 12. The scraper 13 is designed to move along the length direction of the inner frame 11. To achieve smooth guidance, extensions are provided at both ends of the scraper 13, which are slidably fitted into pre-set strip tracks (not shown in the figure) along the length direction of the inner wall of the inner frame 11. When the scraper 13 moves, its blade can effectively push and remove silt, sand, leaves, and other blockages deposited or stuck in the gaps of the grid bars 12.

[0028] The drive assembly utilizes the gravitational potential energy of the drainage to drive the scraper 13. Specifically, a container 5 is positioned directly below the aforementioned pipe 3, with its opening facing upwards, to receive and contain the water discharged from the pipe 3. A vertical first rod 4 is fixed to the pipe connector 2, and the container 5 is fitted onto the first rod 4 via a central extension 14 inside, allowing it to slide up and down along the direction of the first rod 4. Further, the central extension 14 is preferably a column-type structure.

[0029] In order to achieve automatic reset of container 5, a tension spring 6 is set on the periphery of the first rod 4 as an elastic reset component. One end of the tension spring 6 is fixed on the base of the pipe joint 2, and the other end is connected to the central extension 14 of container 5. When container 5 is empty in the initial state, the tension of the tension spring 6 keeps container 5 in the highest position.

[0030] A first conical rod 7 is provided at the lower distal end of the first rod 4, with its conical surface facing downwards and its wide end facing upwards. Several through holes 15 are provided on the inner wall of the central extension 14 of the container 5, with the edges of these through holes 15 extending to the inner bottom of the container 5. When the container 5 is in its highest position, the lower edge of the central extension 14 is much higher than the first conical rod 7, and the through holes 15 are blocked by the smooth rod body of the first rod 4, thus forming a closed water storage space in the container 5.

[0031] The scraper 13 has an adapter 9 at its bottom, which is pivotally connected to one end of the second rod 10. The outer wall of the container 5 has a container adapter groove 16, and the other end of the second rod 10 is rotatably connected to the container adapter groove 16. This forms a linkage mechanism connecting the container 5 and the scraper 13. The vertical linear motion of the container 5 can be converted into the reciprocating linear motion of the scraper 13 by the swinging of the second rod 10.

[0032] To prevent the container 5 from detaching from the guide rod during rapid descent, a second cone rod 8 can be further provided at the bottom of the first cone rod 7, opposite to the first cone rod 7. The diameter of the wide end of the second cone rod 8 is larger than the diameter of the first rod 4, and it can serve as a mechanical limit block for the extreme position.

[0033] Working principle: During rainfall, rainwater enters the interlayer 100 and the interlayer extension 200, and is injected into the container 5 below through the pipe 3.

[0034] As the water level in container 5 rises, its total weight increases. When the weight of the water exceeds the preset tension of the tension spring 6, container 5 begins to overcome the elastic force and slide downward along the first rod 4. During this process, through the linkage of the second rod 10, the scraper 13 is pulled and scrapes along the gap of the grid 12, pushing the blockage to one end.

[0035] When container 5 descends to the preset position, its internal central extension 14 also descends, and the through hole 15 area at its lower end moves to the position of the first cone rod 7. Due to the cone shape of the first cone rod 7, an annular gap is formed between it and the inner wall of the central extension 14. This gap allows the water in container 5 to be quickly discharged through the through hole 15.

[0036] After the water in container 5 is drained, its total weight decreases rapidly. At this point, the tension of spring 6 takes over again, pulling the lighter container 5 back to its initial highest position.

[0037] As container 5 rises, the scraper 13 is pushed in the opposite direction by the linkage of the second rod 10, returning to its initial position, thus completing a complete dredging cycle.

[0038] As long as there is a continuous and sufficient amount of rainwater flowing in, the above cycle will repeat automatically, thus ensuring that the grid gaps of the drainage well cover remain unobstructed and exert its maximum drainage capacity.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
