Description

Technical Field

[0001] This invention relates to the field of manhole cover technology, specifically to a manhole cover structure that is easy to maintain. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material, such as metal manhole covers, high-strength fiber-reinforced concrete manhole covers, and resin manhole covers. They are generally round. They can be used in green belts, sidewalks, driveways, docks, alleyways, etc.

[0003] Currently, most existing manhole cover structures still employ relatively traditional fixing methods, directly installing them at the manhole opening through simple snap-fit ​​or embedding. While this installation method meets the basic functional requirement of covering the manhole opening, over time, especially when uneven ground settlement or changes in surrounding soil conditions occur, a significant height difference often arises between the manhole cover and the ground. During maintenance, due to the lack of flexible adjustment mechanisms in existing structures, maintenance personnel typically have to perform a series of tedious and time-consuming operations, such as mixing cement, gradually raising the base, and waiting for the materials to fully dry and harden. These procedures not only significantly increase labor and material costs but also severely reduce the overall efficiency of maintenance work, posing a considerable challenge to the daily maintenance and management of urban infrastructure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a manhole cover structure that is easy to maintain, solving the problems of inconvenient maintenance and high labor and material costs when there is a height difference between the manhole cover and the ground.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a manhole cover structure that is easy to maintain, comprising a manhole body base, wherein the manhole body base is equipped with a connecting mechanism for connecting to the manhole body base.

[0006] The connecting mechanism includes a pressure cylinder that is slidably connected to the inside of the well body seat. The pressure cylinder is machined with at least one stepped edge, and a plug-in component is fixedly connected to the lowest point of the stepped edge. A snap-fit ​​component is installed at the bottom end of the stepped edge for snap-fit ​​engagement with the stepped edge.

[0007] The snap-fit ​​assembly includes stepped support blocks that are fixedly connected to the inner wall of the well body seat. Each set of stepped support blocks corresponds to the stepped edge, and the slot of the stepped support block is adapted to the plug-in component.

[0008] The number of stepped edges and stepped support blocks should correspond, preferably in groups, for the best support effect. The height and width of the stepped support blocks can be designed according to actual usage requirements. The insert block is machined in the exact center of the stepped support block to ensure that it is on the same vertical line as the insertion structure, so that the insertion structure can be stably inserted into the slot of the stepped support block.

[0009] In some embodiments, the shape of the connector is any one of rectangular, cylindrical, or conical.

[0010] In some embodiments, the connecting mechanism further includes a flange connected to the outer periphery of the pressure cylinder, and the inner wall of the flange is in contact with the outer wall of the well body seat.

[0011] Setting a retaining edge can further enhance the stability of the connection between the pressure cylinder and the well body base, preventing the pressure cylinder from shaking or shifting during use. At the same time, the retaining edge can also play a certain protective role, preventing external debris from entering the connection gap between the well body base and the pressure cylinder and affecting the normal use of the structure. A sealing strip can be set at the part where the retaining edge is in contact with the outer wall of the well body base to further enhance the performance.

[0012] In some embodiments, the flange is integrally formed with the pressure cylinder.

[0013] In some embodiments, a connecting plate is fixed to the lower outer periphery of the well body base for connecting to an external wellhead.

[0014] Threaded holes can be made on the connecting plate to facilitate subsequent installation and fixing work.

[0015] In some embodiments, a support plate is fixed to the inner wall of the pressure cylinder, and the support plate has an opening for drainage.

[0016] The opening in the middle of the support plate makes it easy for operators to lift the pressure cylinder. At the same time, the design of the support plate allows a small amount of liquid to fall directly from the lowest point of the inner ring of the support plate, preventing it from flowing to the stepped edge of the pressure cylinder. This ensures that the connection between the stepped edge and the stepped support block is dry and clean, avoiding structural damage or loosening of the connection due to liquid erosion.

[0017] In some embodiments, a manhole cover is installed on the upper surface of the support plate, and the outer wall of the manhole cover slides in fit with the inner wall of the pressure cylinder.

[0018] In some embodiments, the top of the manhole cover is machined with drainage holes and anti-slip textures.

[0019] In some embodiments, multiple sets of stepped support blocks are provided, and the multiple sets of stepped support blocks are evenly spaced around the centroid of the well body base.

[0020] This distribution method ensures that the support force on the pressure cylinder is more even in all directions, guaranteeing that the pressure cylinder is stably installed on the well body seat and preventing tilting or shaking caused by uneven force, thus further improving the stability and reliability of the entire well cover structure. Furthermore, the equidistantly distributed stepped support blocks in a ring shape make it easier for maintenance personnel to accurately find the appropriate slot to insert the connector when adjusting the pressure cylinder height, making maintenance and adjustment work more efficient and convenient.

[0021] This invention provides a manhole cover structure that is easy to maintain, and has the following beneficial effects: This easy-to-maintain manhole cover structure eliminates the need for cumbersome operations as in traditional methods when uneven ground settlement or changes in surrounding soil conditions cause a height difference between the manhole cover and the ground. Since the pressure cylinder cooperates with the stepped support block through the stepped edge and the plug-in piece, the maintenance personnel only need to lift the pressure cylinder upwards, select the appropriate height of the stepped support block slot according to the actual needs, and insert the plug-in piece to quickly complete the height adjustment.

[0022] This flexible adjustment mechanism greatly saves maintenance time and costs. On the one hand, it avoids time-consuming processes such as mixing cement, raising the base, and waiting for the materials to dry and harden, thus reducing labor costs. On the other hand, it also reduces the amount of materials used, making maintenance work more environmentally friendly and economical. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-3The present invention provides a technical solution: a manhole cover structure that is easy to maintain, including a manhole body base 1, wherein the manhole body base 1 is equipped with a connecting mechanism for connecting to the manhole body base 1.

[0029] The connecting mechanism includes a pressure cylinder 2 that is slidably connected to the inside of the well body seat 1. The pressure cylinder 2 is machined with at least one stepped edge 3, and a plug-in 4 is fixedly connected to the lowest point of the stepped edge 3. A snap-fit ​​component is installed at the bottom end of the stepped edge 3 for snap-fit ​​engagement with the stepped edge 3.

[0030] The snap-fit ​​assembly includes a stepped support block 5 that is fixed to the inner wall of the well body seat 1. Each set of stepped support blocks 5 corresponds to a stepped edge 3, and the slot of the stepped support block 5 is adapted to the plug-in part 4.

[0031] The number of stepped edges 3 and stepped support blocks 5 corresponds to the number of sets, preferably 4 sets, which provides the best support effect. The height and width of the stepped support blocks 5 can be designed according to actual usage requirements. For example, if the height of the stepped support block 5 is designed to be 10mm, then each time one stepped support block 5 is raised, the manhole cover 9, etc., will rise by 10mm. The number of support blocks 5 is 15-20, with 15 being the optimal solution. The insertion hole is machined in the exact center of the stepped support block 5 to ensure that it is on the same vertical line as the connector 4, so that the connector 4 can be stably inserted into the slot of the stepped support block 5.

[0032] In this embodiment, the shape of the connector 4 is any one of rectangle, cylinder, or cone.

[0033] In this embodiment, the connecting mechanism is further configured to include a retaining edge 6 connected to the outer periphery of the pressure cylinder 2, and the inner wall of the retaining edge 6 is in contact with the outer wall of the well body seat 1.

[0034] Setting the baffle 6 can further enhance the stability of the connection between the pressure cylinder 2 and the well body seat 1, preventing the pressure cylinder 2 from shaking or shifting during use. At the same time, the baffle 6 can also play a certain protective role, preventing external debris from entering the connection gap between the well body seat 1 and the pressure cylinder 2 and affecting the normal use of the structure. A sealing strip can be set at the part where the baffle 6 is in contact with the outer wall of the well body seat 1 to further enhance the use effect.

[0035] In this embodiment, the flange 6 and the pressure cylinder 2 are integrally formed.

[0036] In this embodiment, a connecting plate 7 is fixedly connected to the lower outer periphery of the well body base 1 for connecting to the external wellhead.

[0037] Threaded holes can be made on the connecting plate 7 to facilitate subsequent installation and fixing work.

[0038] In this embodiment, the inner wall of the pressure cylinder 2 is further configured to have a support plate 8 fixedly connected to it, and the support plate 8 has an opening for drainage.

[0039] The opening in the middle of the support plate 8 makes it easy for operators to lift the pressure cylinder 2, etc. At the same time, when a small amount of liquid flows through the support plate 8, it can fall directly from the lowest point of the inner ring of the support plate 8, so that it is not easy to flow to the stepped edge 3 of the pressure cylinder 2. This ensures that the connection between the stepped edge 3 and the stepped support block is dry and clean, and avoids structural damage or loosening of the connection due to liquid erosion.

[0040] In this embodiment, a manhole cover 9 is installed on the upper surface of the support plate 8, and the outer wall of the manhole cover 9 slides in conjunction with the inner wall of the pressure cylinder 2.

[0041] In this embodiment, the top of the manhole cover 9 is further provided with drainage holes and anti-slip texture.

[0042] In this embodiment, the stepped support blocks 5 are arranged in multiple sets, and the multiple sets of stepped support blocks 5 are evenly spaced around the centroid of the well body seat 1.

[0043] This distribution method ensures that the supporting force on the pressure cylinder 2 is more even in all directions, guaranteeing that the pressure cylinder 2 is stably installed on the well body seat 1 and preventing tilting or shaking of the pressure cylinder 2 due to uneven force distribution, thus further improving the stability and reliability of the entire well cover structure. In addition, the ring-shaped stepped support blocks 5 also make it easier for maintenance personnel to find the appropriate slot to insert the plug-in structure 4 when adjusting the height of the pressure cylinder 2, making maintenance and adjustment work more efficient and convenient.

[0044] The following describes a specific embodiment of this application with reference to the accompanying drawings: When this device is needed, the components can be assembled according to the diagram according to the assembly process to ensure that the welding is firm. Before work, each structure is cleaned. Then, the pressure cylinder 2 is moved into the well body seat 1 by the support plate 8, and the inner wall of the retaining edge 6 is made to fit with the outer wall of the well body seat 1. At the same time, in the initial stage, the plug 4 at the lowest point of the step edge 3 can be inserted into the slot at the lowest point of each set of step support blocks 5. Then, the well cover 9 is installed on the support plate 8 in the pressure cylinder 2.

[0045] When uneven ground settlement or changes in the surrounding soil cause a significant height difference between the manhole cover 9 and the ground, the manhole cover can be disassembled first. Then, the pressure cylinder 2 can be lifted by the support plate 8, and the pressure cylinder 2 can be rotated in the direction of the rise of the stepped support block 5 so that the connector 4 can be inserted into the slot of the other stepped support block 5. In this way, the manhole cover 9 can be adjusted to a suitable height to solve the problem of the height difference between the manhole cover and the ground.

[0046] This adjustment method is simple to operate, eliminating the need for tedious and time-consuming procedures such as mixing cement, raising the base, and waiting for the material to dry and harden, as required by traditional methods. This greatly reduces labor and material costs and improves the efficiency of maintenance work. Moreover, since several sets of stepped support blocks 5 are distributed in a ring at equal intervals around the centroid of the well body base 1, the pressure cylinder 2 can rotate relatively smoothly when adjusting the height, ensuring the stability of the adjustment process. At the same time, the flange 6 is integrally formed with the pressure cylinder 2, which not only ensures the strength of the structure but also prevents debris from entering the connection between the well body base 1 and the pressure cylinder 2, reducing damage to the connection structure and further extending the service life of the well cover structure.

[0047] In addition, the drainage holes and anti-slip textures machined on the top of the manhole cover 9 not only drain water but also provide safety for pedestrians and vehicles, preventing accidents such as slipping due to water accumulation.

[0048] During routine maintenance, maintenance personnel only need to periodically check the connection between the plug-in structure 4 and the stepped support block 5, as well as whether the drainage hole is blocked, to ensure the normal operation of this easy-to-maintain manhole cover structure.
