[0002] Concrete manhole covers, as the name suggests, are manhole covers made of concrete and used to cover various manholes, such as drainage manholes, power manholes, and communication manholes.

[0003] However, existing concrete manhole covers are heavy, and their installation and replacement require a lot of physical strength and time from workers. In addition, when used for drainage wells, during the drainage process, not only are items that people accidentally drop on the ground easily carried into the well by the water flow, but it also poses a safety hazard to passersby.

[0004] Therefore, it is necessary to provide a lightweight concrete manhole cover for solid waste to solve the above-mentioned technical problems. Utility Model Content

[0006] The solid waste lightweight concrete manhole cover provided by this utility model includes: a cover ring and a concrete manhole cover installed on a drainage well, both the cover ring and the concrete manhole cover having annular cavities, and both annular cavities having solid waste lightweight aggregate inside; a wire mesh fixedly installed at the bottom of the concrete manhole cover for blocking objects, the wire mesh being located inside the cover ring; mounting holes opened on the concrete manhole cover; and a height adjustment mechanism for raising and lowering the concrete manhole cover, assembled on the mounting holes and the cover ring.

[0007] Preferably, the height adjustment mechanism includes: a rotating plate rotatably mounted on the inner wall of the mounting hole, a screw fixedly mounted on the bottom of the rotating plate, and a threaded sleeve threaded onto the screw; and multiple support frames fixedly mounted on the threaded sleeve, each of the multiple support frames being fixedly connected to the bottom of the cover ring.

[0008] Preferably, the top of the rotating plate is provided with a storage groove, and the inner wall of the storage groove is hinged with two handles.

[0009] Preferably, the inner wall of the cover ring has two limiting grooves, and the inner walls of the two limiting grooves are slidably installed with limiting blocks, and the two limiting blocks are fixedly connected to the wire mesh.

[0010] Preferably, the wire mesh is arranged in a ring shape and is made of stainless steel.

[0011] Preferably, both handles are fitted with protective sleeves, and both protective sleeves are made of rubber material.

[0012] Preferably, a bearing is fixedly installed on the inner wall of the mounting hole, and the inner ring of the bearing is fixedly connected to the rotating plate.

[0013] Compared with related technologies, the lightweight concrete manhole cover for solid waste provided by this utility model has the following beneficial effects:

[0014] This utility model provides a lightweight concrete manhole cover for solid waste. By creating annular cavities in the cover ring and concrete manhole cover and filling them with lightweight aggregate from solid waste, the overall weight of the manhole cover can be effectively reduced while maintaining its structural strength. This reduces the physical effort and time required for installation. The height adjustment mechanism allows for easy raising and lowering of the concrete manhole cover and wire mesh. When the wire mesh is exposed during the raising and lowering process, the manhole cover is in a drainage state, allowing water to flow through the mesh into the drainage well. The wire mesh also prevents objects from entering the well with the water flow, thus preventing falling objects. During drainage, the well opening is not exposed, preventing pedestrians from falling into the well and improving safety. This effectively solves the technical problems of existing concrete manhole covers, such as excessive weight, difficulty in installation and replacement, and the risk of objects falling and safety hazards when the drainage well is open.

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a lightweight concrete manhole cover for solid waste, such as... Figure 1-4 As shown, the solid waste lightweight concrete manhole cover includes: a cover ring 1 and a concrete manhole cover 2 installed on the drainage well 14, both the cover ring 1 and the concrete manhole cover 2 having annular cavities 15, and both annular cavities 15 having solid waste lightweight aggregate 3 inside; a wire mesh 4 fixedly installed at the bottom of the concrete manhole cover 2 for blocking objects, the wire mesh 4 being located inside the cover ring 1; mounting holes 5 opened on the concrete manhole cover 2; and a height adjustment mechanism for raising and lowering the concrete manhole cover 2, assembled on the mounting holes 5 and the cover ring 1.

[0023] In this embodiment, by creating annular cavities 15 on the cover ring 1 and the concrete manhole cover 2 and filling them with solid waste lightweight aggregate 3, the overall weight of the manhole cover is reduced by utilizing the lightweight and high-strength characteristics of the solid waste lightweight aggregate 3, while ensuring its structural strength. When drainage work is required using the drainage well 14, the operator needs to use the height adjustment mechanism to move the concrete manhole cover 2 and the wire mesh 4 upwards until the wire mesh 4 is exposed. At this time, the manhole cover is in a drainage state, allowing water to flow through the mesh of the wire mesh 4 into the drainage well 14. At this time, the wire mesh 4 can also prevent ground objects from entering the well with the water flow, thus playing a role in preventing falling objects. During the drainage process, since the opening of the drainage well 14 is not exposed, it can also prevent pedestrians from falling into the well, thereby improving the safety of use.

[0024] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a rotating plate 6 rotatably mounted on the inner wall of the mounting hole 5, a screw 7 fixedly mounted on the bottom of the rotating plate 6, and a threaded sleeve 8 threadedly mounted on the screw 7; and a plurality of support frames 9 fixedly mounted on the threaded sleeve 8, all of which are fixedly connected to the bottom of the cover ring 1.

[0025] In this embodiment, the height adjustment mechanism is used to raise and lower the concrete manhole cover 2. When in use, the rotating plate 6 is rotated by hand, so that the screw 7 at the bottom of the rotating plate 6 rotates on the screw sleeve 8. Since the screw sleeve 8 cannot move, the screw 7 can move vertically on the screw sleeve 8. The screw 7 will drive the rotating plate 6, the concrete manhole cover 2 and the wire mesh 4 to move vertically. When the wire mesh 4 is exposed, the manhole cover can perform drainage work, which is more convenient to use.

[0026] In a further preferred embodiment of the present invention, a storage groove 10 is provided on the top of the rotating plate 6, and two handles 11 are hinged to the inner wall of the storage groove 10.

[0027] In this embodiment, the two handles 11 are removed from the storage slot 10 by flipping them over, which makes it convenient for personnel to use the two handles 11 to rotate the rotating plate 6.

[0028] In a further preferred embodiment of the present invention, two limiting grooves 12 are provided on the inner wall of the cover ring 1, and limiting blocks 13 are slidably installed on the inner walls of the two limiting grooves 12, and the two limiting blocks 13 are fixedly connected to the wire mesh 4.

[0029] In this embodiment, the combined use of two limiting grooves 12 and two limiting blocks 13 can ensure the stability of the concrete manhole cover 2 and the wire mesh 4 during vertical lifting and lowering, and prevent them from rotating during lifting and lowering.

[0030] In a further preferred embodiment of this utility model, the wire mesh 4 is configured as a ring, and the wire mesh 4 is made of stainless steel.

[0031] In this embodiment, the stainless steel wire mesh 4 has good corrosion resistance and durability, is not easily damaged, and has a good service life.

[0032] In a further preferred embodiment of the present invention, protective sleeves are fixedly fitted on both handles 11, and both protective sleeves are made of rubber material.

[0033] In this embodiment, the protective sleeve made of rubber material can improve the softness of the operator's hand when gripping the handle 11, thereby improving the operator's grip comfort.

[0034] In a further preferred embodiment of this utility model, a bearing is fixedly installed on the inner wall of the mounting hole 5, and the inner ring of the bearing is fixedly connected to the rotating plate 6.

[0035] In this embodiment, the use of bearings enables a rotatable connection between the rotating plate 6 and the mounting hole 5, thereby keeping the rotating plate 6 stable during rotation.

[0036] In summary, compared with related technologies, this solution effectively reduces the overall weight of the manhole cover by creating annular cavities 15 in the cover ring 1 and the concrete manhole cover 2 and filling them with solid waste lightweight aggregate 3, while ensuring its structural strength. This reduces the physical effort and time required for installation. The height adjustment mechanism allows for easy raising and lowering of the concrete manhole cover 2 and the wire mesh 4. When the wire mesh 4 is exposed during the raising and lowering process, the manhole cover is in a drainage state, allowing water to flow through the mesh of the wire mesh 4 into the drainage well 14. The wire mesh 4 prevents objects from entering the well with the water flow, thus preventing falling objects. During drainage, the well opening of the drainage well 14 is not exposed, preventing pedestrians from falling into the well and improving safety. This solution effectively solves the technical problems of existing concrete manhole covers, such as excessive weight, difficulty in installation and replacement, and the risk of objects falling and safety hazards during the opening of the drainage well.
