Description

Technical Field

[0001] This utility model relates to the field of drainage well cover technology, specifically to a municipal drainage well cover structure that prevents clogging. Background Technology

[0002] In municipal drainage systems, manhole covers are crucial components, used to cover drainage well openings, ensuring the safety of pedestrians and vehicles, and guiding rainwater and other water bodies into drainage pipes. However, traditional municipal drainage manhole covers are prone to clogging: everyday debris such as fallen leaves, plastic bags, and stones can easily flow into the manhole cover with rainwater, directly clogging the drainage pipe inlet or inside the pipe itself, leading to flooding on roads during rainy days, affecting traffic, and potentially causing urban flooding. Furthermore, cleaning after clogging is difficult, requiring significant manpower and resources, and disrupting the normal operation of the drainage system. Therefore, there is an urgent need for a municipal drainage manhole cover structure that is anti-clogging and easy to clean to address the shortcomings of existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a clog-resistant municipal drainage manhole cover structure to solve the problems mentioned in the background art, such as the ease with which traditional municipal drainage manhole covers are clogged by foreign objects and the inconvenience of cleaning. To achieve the above objective, this utility model provides the following technical solution: A clog-resistant municipal drainage well cover structure includes a well cover body, which serves as the basic support component of the entire well cover structure and is used to cooperate with the drainage well opening for installation. The well cover body is threaded with first fixing bolts at its four right angles. The first fixing bolts can securely fix the well cover body to the edge of the drainage well opening, ensuring the stability of the well cover after installation and preventing displacement when vehicles or pedestrians pass by. The well cover body has threaded slots that cooperate with the first fixing bolts to ensure the secure installation of the first fixing bolts.

[0004] Preferably, a partition is engaged at the upper end of the manhole cover body, and equidistant grids are evenly distributed in the middle of the partition. The size of the grids is reasonably designed to initially intercept larger foreign objects such as plastic bags, branches, and stones without affecting the normal infiltration of rainwater, preventing them from directly entering the depth of the manhole cover. Mounting plates are fixedly connected to the left and right sides of the partition. The mounting plates and the manhole cover body have matching grooves. The partition is engaged with the manhole cover body through the mounting plates, achieving quick positioning and installation of the partition and the manhole cover body. A second fixing bolt is also threaded into the mounting plate, passing through both the mounting plate and the manhole cover body, further fixing the partition to the manhole cover body and preventing it from falling off under rainwater impact or external force. The manhole cover body has threaded slots that mate with the second fixing bolt, ensuring the fixing effect of the second fixing bolt.

[0005] Preferably, a filter plate is installed at the lower middle position of the manhole cover body. The filter plate has an inverted V-shaped structure. This design increases the filtration area and improves filtration efficiency. Furthermore, it utilizes gravity to quickly divert rainwater to both sides, while intercepted small foreign objects slide down the inclined surface of the filter plate for easy collection. Handles are fixedly connected to the upper left and right sides of the filter plate, allowing workers to quickly remove it for cleaning or maintenance. Mounting blocks are fixedly connected to the four corners of the lower end of the filter plate, and corresponding fixing plates are fixedly connected to the manhole cover body. The fixing plates have slots that mate with the mounting blocks. The filter plate is secured to the fixing plates via the mounting blocks, enabling detachable installation. A rubber ring is fixedly connected to the lower end of the mounting block. The elastic rubber ring fills the gap between the mounting block and the slot, enhancing the sealing and stability of the connection between the mounting block and the fixing plate, preventing the filter plate from shaking during use.

[0006] Preferably, connecting plates are fixedly connected to the lower left and right sides of the manhole cover body. A mesh collection frame is movably engaged at the lower end of the connecting plates. Trapezoidal blocks are provided on the upper left and right sides of the mesh collection frame. The connecting plates have slots that cooperate with the trapezoidal blocks. The cooperation design of the trapezoidal blocks and slots allows the mesh collection frame to be quickly engaged with the connecting plates and is easy to disassemble. The size of the mesh collection frame is larger than the outer size of the filter plate and is located at the lower end of the filter plate. It can comprehensively receive small foreign objects that slide off the filter plate and a small amount of fine impurities after being filtered by the filter plate, realizing the centralized collection of foreign objects and preventing impurities from accumulating inside the manhole cover and causing blockage.

[0007] Beneficial effects This utility model features a partition and an installation plate. The equidistant grids on the partition effectively block larger foreign objects carried by rainwater, preventing them from entering the drainage pipes and causing blockages. The partition is connected to the manhole cover body via the installation plate and secured by a second fixing bolt. When a large number of foreign objects are blocked on the partition, workers can quickly remove the partition from the manhole cover body for cleaning by disassembling the second fixing bolt. The operation is convenient, the cleaning efficiency is high, and it does not affect the normal use of the manhole cover.

[0008] This utility model features a filter plate and an installation block. The filter plate, with its inverted V-shaped structure, performs secondary filtration on rainwater after the initial filtration by the partition, intercepting fine impurities and further improving the filtration effect. The filter plate is secured to a fixed plate by the installation block, and the handle design allows for quick disassembly for cleaning or replacement. The rubber ring at the lower end of the installation block enhances the stability and sealing of the filter plate after installation. A grid collection frame, larger than the outer dimensions of the filter plate and located at its lower end, collects foreign objects and fine impurities that slide off the filter plate, ensuring unified collection and preventing accumulation of impurities inside manhole covers or drainage pipe inlets, effectively preventing drainage blockage. The grid collection frame is also easily disassembled and regularly cleaned by trapezoidal locking blocks, reducing maintenance costs.

[0009] This utility model has a reasonable overall structural design. Through a three-stage anti-clogging design of initial interception, secondary filtration and centralized collection, it can completely block foreign objects of different sizes from entering the drainage pipe, with a significant anti-clogging effect. Moreover, all core components adopt a detachable installation structure, which is simple to operate and convenient for daily maintenance and cleaning, ensuring the smooth operation of the drainage system and making it highly practical.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Please see Figure 1-5 This utility model provides a technical solution: A clog-resistant municipal drainage well cover structure includes a well cover body 1. First fixing bolts 2 are inserted at the four right angles of the well cover body 1. There are four sets of first fixing bolts 2, and all four sets of first fixing bolts 2 are threaded into the four corners of the well cover body 1. The well cover body 1 has threaded slots that cooperate with the first fixing bolts 2. The well cover body 1 is fixed to the edge of the drainage well opening by the first fixing bolts 2, ensuring that the well cover is installed firmly.

[0012] A partition plate 3 is engaged at the upper end of the manhole cover body 1. Equivalent grids are evenly distributed in the middle of the partition plate 3. Mounting plates 4 are fixedly connected to the left and right sides of the partition plate 3. The partition plate 3 is engaged with the manhole cover body 1 through the mounting plates 4. The manhole cover body 1 has a slot that matches the mounting plates 4. A second fixing bolt 5 is threaded into the mounting plate 4. The second fixing bolt 5 is also threaded into the manhole cover body 1. The mounting plate 4 and the manhole cover body 1 have threaded slots that match the second fixing bolt 5. The second fixing bolt 5 achieves a firm connection between the partition plate 3 and the manhole cover body 1.

[0013] A filter plate 6 is installed at the lower middle position of the manhole cover body 1. The filter plate 6 has an inverted V-shaped structure. Handles are fixedly connected to the upper left and right sides of the filter plate 6. Mounting blocks 7 are fixedly connected to the four corners of the lower end of the filter plate 6. A fixing plate 8 is fixedly connected to the manhole cover body 1. The fixing plate 8 has slots that cooperate with the mounting blocks 7. The filter plate 6 is engaged with the fixing plate 8 by the mounting blocks 7. A rubber ring is fixedly connected to the lower end of the mounting blocks 7 to enhance the sealing and stability of the connection between the mounting blocks 7 and the fixing plate 8. The two sets of mounting blocks 7 are fixedly connected to the manhole cover body 1 on the side that is far away from each other, which further improves the installation stability of the filter plate 6.

[0014] The lower left and right sides of the manhole cover body 1 are fixedly connected to connecting plates 9. The lower end of the connecting plate 9 is engaged with a grid collection frame 10. The upper left and right sides of the grid collection frame 10 are movably engaged with the connecting plate 9 by trapezoidal locking blocks. The connecting plate 9 is provided with a locking groove that matches it. The size of the grid collection frame 10 is larger than the outer size of the filter plate 6. The grid collection frame 10 is located at the lower end of the filter plate 6 and is used to collect foreign objects that slide down from the filter plate 6.

[0015] Working principle When the anti-clogging municipal drainage well cover structure is put into use, the well cover body 1 is first securely installed at the edge of the drainage well opening by the first fixing bolts 2 at the four right angles of the well cover body 1, ensuring that the entire well cover structure is installed firmly and avoiding displacement during use.

[0016] During rainfall, rainwater carries foreign objects from the ground towards the manhole cover. It first contacts the partition 3 at the upper end of the manhole cover body 1. The equidistant grids on the partition 3 perform preliminary filtration of the rainwater, intercepting larger objects such as plastic bags, branches, and larger stones above the partition 3 to prevent them from entering the manhole cover. The pre-filtered rainwater passes through the grids into the manhole cover body 1 and then flows to the inverted V-shaped filter plate 6 below. The filter plate 6 performs secondary filtration, intercepting fine impurities such as sand and broken leaves. Simultaneously, the inverted V-shaped structure causes the rainwater to quickly divert to both sides under gravity, increasing drainage speed. The intercepted fine impurities slide down the inclined surface of the filter plate 6 into the grid collection frame 10 below, achieving centralized collection of impurities.

[0017] After a period of use, larger foreign objects will accumulate on the baffle 3, some impurities may adhere to the surface of the filter plate 6, and a certain amount of fine impurities will also be collected in the mesh collection frame 10. At this time, cleaning and maintenance are required. The operator can first unscrew the second fixing bolt 5 to release the fixing of the mounting plate 4 to the manhole cover body 1, then remove the baffle 3 from the manhole cover body 1, clean the foreign objects on the baffle 3, and after cleaning, reset the baffle 3 by cooperating with the mounting plate 4 and the slot, and then tighten the second fixing bolt 5.

[0018] To clean the filter plate 6, the operator can apply upward pulling force through the handle at the top of the filter plate 6 to disengage the mounting block 7 at the bottom of the filter plate 6 from the slot of the fixing plate 8, thereby removing the filter plate 6 and cleaning the impurities attached to its surface. After cleaning, the mounting block 7 is aligned with the slot of the fixing plate 8 and inserted. The rubber ring at the bottom of the mounting block 7 is used to enhance the fixing effect, thus completing the reinstallation of the filter plate 6.

[0019] When there are many impurities collected in the grid collection frame 10, the staff can pull the grid collection frame 10 down directly to disengage the trapezoidal block at the top from the slot of the connecting plate 9. After removing the grid collection frame 10, the internal impurities can be poured out. After cleaning, the trapezoidal block can be aligned with the slot and inserted to reset the grid collection frame 10.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended features rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the features be included within this invention. The scope of this invention is defined by its equivalents.
