[0006] As a further embodiment of this utility model: the water accumulation mechanism also includes a protrusion integrally formed between the outer water accumulation area and the central water accumulation area. The protrusion has an upward convex structure, and multiple overflow ports are provided at the highest point of the protrusion. The multiple overflow ports are equidistantly distributed in the circumferential direction.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0012] Please see Figures 1-3 In this embodiment of the utility model, the invisible manhole cover for grassland includes a manhole cover body 1. The manhole cover body 1 has a sunken structure and an open structure at the top. A water accumulation mechanism is formed at the bottom of the inner wall of the manhole cover body 1. A support ring 4 is integrally formed on the upper outer periphery of the manhole cover body 1. A reinforcing rib 3 is welded on the inside corner of the support ring 4. A ventilation hole 2 is opened on the upper inner periphery of the manhole cover body 1, extending to the outside of the manhole cover body 1. There are multiple ventilation holes 2, which are equidistantly distributed in the circumferential direction.

[0013] In this embodiment: First, the manhole cover body 1 is connected to the top opening of the sewer well. The support ring 4 on the installed manhole cover body 1 abuts against the lawn. Then, soil is filled into the inner cavity of the manhole cover body 1 and grass seeds are sown. After the grass seeds germinate and grow, they can cover the manhole cover body 1, thereby achieving the purpose of hiding the manhole cover body 1. During the use of the manhole cover body 1, the ventilation hole 2 can increase the contact area between the manhole cover body 1 and the air, avoiding the continuous accumulation of heat in the manhole cover body 1 in summer and facilitating the heat dissipation of the manhole cover body 1. The water collection mechanism at the bottom of the manhole cover body 1 can collect water and discharge excess water when there is too much water.

[0014] Please refer to this carefully. Figure 2The water collection mechanism includes an outer water collection area 5 formed on the outer periphery of the top of the bottom plate of the manhole cover body 1, and a central water collection area 6 formed at the center of the bottom plate of the manhole cover body 1. The outer water collection area 5 and the central water collection area 6 have a downwardly recessed structure. The water collection mechanism also includes a protrusion 11 integrally formed between the outer water collection area 5 and the central water collection area 6. The protrusion 11 has an upwardly raised structure. Multiple overflow ports 7 are provided at the highest point of the protrusion 11. The multiple overflow ports 7 are equidistantly distributed in the circumferential direction.

[0015] In this embodiment: during rainfall, rainwater enters the interior of the manhole cover body 1 through the soil, and the rainwater can accumulate in the outer water accumulation area 5 and the central water accumulation area 6. As the rainwater gradually increases, the excess rainwater overflows from the overflow outlet 7 after passing the highest point of the protrusion 11, thus avoiding excessive accumulation of rainwater.

[0016] Please refer to this carefully. Figure 2 and Figure 3 The inner circumference of the manhole cover body 1 is symmetrically formed with two connecting blocks 8. The lower outer side of the connecting block 8 is formed with a connecting groove 10 for connecting with the sewer well. The top plate of the connecting block 8 is provided with a connecting hole 9 that communicates with the connecting groove 10.

[0017] In this embodiment: the docking groove 10 is docked with the docking part at the top opening of the sewer well, so as to facilitate the docking of the manhole cover body 1. When disassembling the manhole cover body 1, a tool is used to pass through the connecting hole 9, and then the manhole cover body 1 can be pulled up by the tool to facilitate the disassembly of the manhole cover body 1.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
