[0002] In related technologies, for safety and closure reasons, manhole covers are mostly made of a single piece of heavy cast iron to completely seal the manhole opening. Some manhole covers have ventilation holes, but these holes are small to prevent objects from falling in. With the existing manhole cover structure, it cannot assist in rapid rainwater drainage during periods of increased seasonal rainfall, leading to a decrease in the availability of underground drainage networks. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a suspended drainage well cover, which has the advantage of rapid water drainage.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] Existing manhole cover structures have drainage holes that are too small or too few on the end face. When seasonal rainfall increases, the drainage holes cannot drain water quickly, and impurities in the water can easily cause the drainage holes to become blocked, which cannot help to drain rainwater quickly and reduces the availability of underground drainage networks.

[0037] Therefore, such as Figures 1 to 7As shown, the suspended drainage well cover proposed in this utility model includes: a base 300, a filter sleeve 200, and a floating cover 100. A drainage well is formed on the outer surface of the ground. The base 300 is provided with a drainage outlet 310, which is located above the drainage well. The filter sleeve 200 is arranged around the drainage outlet 310, allowing water to flow through the filter sleeve 200 into the drainage outlet 310. One end of the filter sleeve 200 is connected to the base 300, and the filter sleeve 200 is made of a flexible material. The other end of the filter sleeve 200 can extend outward. The floating cover 100 is connected to the base 300. The filter sleeve 200 has one end facing away from the base 300. The floating cover 100 is adapted to cover the drain outlet 310. In a static state, it can cover the drain outlet 310 to prevent debris from falling directly into the drainage pipe. The floating cover 100 is rigid, preventing it from collapsing when stepped on by pedestrians or vehicles. Furthermore, the buoyancy of the floating cover 100 in water is greater than its own weight. When the ground water level rises, the floating cover 100 can float upwards and pull the filter sleeve 200 upwards, increasing the surface area of ​​the filter sleeve 200's peripheral wall to drive water flow through the peripheral wall of the filter sleeve 200 into the drain outlet 310. It should be noted that the base 300 is made of a sturdy and corrosion-resistant material, such as ductile iron or stainless steel. The drain outlet 310 can be circular, square, or other suitable geometric shapes. Its size and shape are designed according to the drainage flow requirements and manhole cover specifications to ensure that no water accumulation occurs under normal drainage conditions.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the outer surface of the floating cover 100 is decorated with a pattern, which is a design of an ancestral hall. The ancestral hall design includes elements such as a gate, stone lions, steps, and eaves. The ancestral hall has three gates, which are evenly spaced. Two lions are symmetrically distributed on the left and right sides of the ancestral hall. The ancestral hall design is visually appealing and grand, and the pattern is vivid and rich. In some other embodiments, the drainage well cover is applied to the ancestral hall.

[0039] In some embodiments of this utility model, the filter sleeve 200 is made of fiber. The filter sleeve 200 is formed with filter holes of a specific pore structure through a special weaving process. The pore size can effectively intercept debris such as leaves, mud particles, and hair, while allowing water to flow smoothly.

[0040] In some embodiments of this utility model, such as Figure 1 and Figure 7As shown, the filter sleeve 200 is provided with a first fixing member 210. There are multiple first fixing members 210. The first fixing members 210 are fixedly connected to the filter sleeve 200, and can be connected by elastic snap fasteners, threaded connections, welding connections, adhesive connections, etc. Here, there is no restriction on the specific connection method between the first fixing member 210 and the filter sleeve 200, as long as the requirement of not detaching the filter sleeve 200 from the first fixing member 210 is met. One end of the first fixing member 210 is provided with a limiting block 211. The floating cover 100 is provided with a first insertion groove 110, which extends along the center line of the floating cover 100. There are multiple first insertion grooves 110, which are distributed at intervals around the center of the floating cover 100. The first fixing member 210 is inserted into the first insertion groove 110 to achieve a fixed connection between the filter sleeve 200 and the floating cover 100. The limiting block 211 abuts against the end face of the floating cover 100 to prevent the floating cover 100 from detaching from the filter sleeve 200. The insertion and engagement of the first fixing member 210 and the first insertion groove 110 not only provides axial connection but also positions the floating cover 100 radially. This prevents the floating cover 100 from shifting, wobbling, or rotating radially relative to the filter sleeve 200. This is crucial to ensuring that the floating cover 100 can accurately cover the drain outlet 310.

[0041] Furthermore, in some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, the filter sleeve 200 is provided with a second fixing member 220. The connection method between the second fixing member 220 and the filter sleeve 200 can be referred to the connection method between the first fixing member 210 and the filter sleeve 200, which will not be described in detail here. The base 300 is provided with a second insertion groove 320. The second fixing member 220 is inserted into the second insertion groove 320 to realize the filter sleeve 200 is fixedly connected to the base 300. The insertion and engagement method facilitates the replacement or cleaning and maintenance of the filter sleeve 200, and the filter sleeve 200 can be easily removed for replacement, cleaning or maintenance.

[0042] Specifically, in some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, the second insertion groove 320 extends circumferentially along the base 300, and the end of the second fixing member 220 is provided with a limiting protrusion 221. The second fixing member 220 cooperates with the second insertion groove 320, and the limiting protrusion 221 abuts against the outer peripheral wall of the base 300 to limit the axial displacement at the connection between the filter sleeve 200 and the base 300. Compared with traditional connection methods such as welding and bolting, the insertion-fit connection method does not require complex tools and professional installation skills, greatly reducing the installation difficulty.

[0043] In some embodiments of this utility model, such as Figure 4 As shown, when there is no water flowing over the ground or the water level is lower than the floating cover 100, the floating cover 100 closes the drain outlet 310, the floating cover 100 abuts against the end of the base 300, and the filter sleeve 200 is housed within the base 300. In other embodiments, such as Figure 5 As shown, when the ground water level is higher than the floating cover 100, the floating cover 100 is driven to rise by buoyancy, thus achieving rapid water discharge.

[0044] Specifically, in some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6 As shown, the base 300 includes a load-bearing body 340 and a fixed base 330. The load-bearing body 340 and the fixed base 330 are plugged and fixed together. The load-bearing body 340 is used to support the floating cover 100. The load-bearing body 340 is usually made of high-strength metal or plastic materials, such as ductile iron, stainless steel, or alloy steel, which have excellent compressive strength and can stably support the floating cover 100, ensuring that it will not deform or be damaged when stepped on by pedestrians or vehicles. The fixed base 330 provides a stable installation foundation and can be tightly connected to the ground or other supporting surfaces.

[0045] In some embodiments of this utility model, such as Figure 1 , Figures 3 to 5 As shown, a reinforcing rib 331 is provided between the fixed base 330 and the load-bearing body 340. There are multiple reinforcing ribs 331, which effectively distribute the weight borne by the load-bearing body 340 evenly to the fixed base 330. The multiple reinforcing ribs 331 are used to reinforce the load-bearing body 340, which improves the stability and reliability of the entire structure when subjected to external pressures such as pedestrians and vehicles stepping on it, and ensures that the manhole cover can play its functional role stably for a long time.

[0046] In some embodiments of this utility model, such as Figure 1 , Figures 3 to 5 As shown, the fixed base 330 is provided with multiple weight-reducing grooves 332. The multiple weight-reducing grooves 332 are evenly distributed and pass through the fixed base 330. The weight-reducing grooves 332 are used to reduce the weight of the fixed base 330. The lighter parts are easier to operate and transport, which can improve construction efficiency, save materials, and reduce the manufacturing cost of the fixed base 330.

[0047] In some embodiments of this utility model, the floating cover 100 is equipped with an anti-theft component (not shown in the figure). The anti-theft component is used to lock the floating cover 100. The anti-theft component is wirelessly connected to a wireless control terminal. Operators can remotely control the anti-theft component through the wireless control terminal to remotely lock the floating cover 100, preventing pedestrians from kicking over or accidentally opening the floating cover 100, which could damage the manhole cover. It also provides good anti-theft protection in dry weather. It is understood that, to prevent moisture intrusion, the anti-theft component uses waterproof components and is sealed.

[0048] In some embodiments of this utility model, the anti-theft component is disposed on the lower end face of the floating cover 100. The anti-theft component is provided with a locking rod, and the load-bearing body 340 is provided with a lock hole for use with the locking rod. The anti-theft component also includes an electric push rod and a controller. The electric push rod is connected to the locking rod, and the controller can remotely control the electric push rod to push the locking rod to lock the floating cover 100.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
