DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] As Figures 1 to 4 shown, a high-safety ecological well lid, including cover body 1, cover body 1 one side is provided with pivot seat 2, pivot seat 2 top rotationally connected cover plate 3, cover body 1 bottom surface circumferential surface is fixedly connected with pre-tightening piece 4, pre-tightening piece 4 is used to fasten cover body 1, cover body 1 middle part is detachably connected with anti-falling net 5, anti-falling net 5 is used to avoid mis-falling;Cover body 1 and cover plate 3 are mutually clamped, and anti-dropping assembly 6 is arranged between cover body 1 and cover plate 3, and anti-dropping assembly 6 is used to prevent cover body 1 from being impacted and turned up;

[0025] It should be noted that the top end of the cover plate 3 is uniformly provided with an anti-skid block 7 for preventing pedestrians from slipping when walking, and an ecological landscape block is arranged on the top surface of the cover plate 3 higher than each anti-skid block 7 for improving the cultural landscape beauty of the area where the well lid is located. In particular, the ecological landscape block base part is provided with a water passage 8 for well lid drainage, and the cover plate 3 bottom surface is fixedly connected with a weight-increasing disc 9 for improving the overall weight of the cover plate 3 and improving the pressure resistance to excessive water flow backflow impact, cooperating with the anti-dropping assembly 6 to prevent the cover body 1 from being impacted and turned up by the water flow.

[0026] As Figure 1 andFigure 2 As shown, the pre-tightening member 4 includes a pre-tightening plate 41 fixedly connected to the bottom surface of the cover body 1, the pre-tightening plate 41 is uniformly provided with ten fastening grooves 42 along the circumferential side surface, and ten reinforcing rib plates 43 are fixedly connected between the cover body 1 and the pre-tightening plate 41;

[0027] It should be noted that the cover plate 3 is rotationally connected with the cover body 1, and when the manhole cover is installed, a concrete layer is poured on the installation foundation surface, and the pre-tightening member 4 is fixed to the concrete surface by fixing bolts along the pre-tightening plate 41 in the circumferential direction of the concrete layer, so as to fix the pre-tightening member 4 to the concrete surface. In particular, the top layer of the concrete surface is lower than the height of the road surface, so as to ensure that the top end of the manhole cover is flush with the installation road surface after installation, that is, by using the bolt fastening between the pre-tightening member 4 and the concrete layer arranged on the bottom layer of the installation road surface, the overall displacement of the manhole cover after installation is effectively avoided, the installation stability is improved, and the manhole cover is also effectively prevented from being separated from the installation pipeline when being impacted by the backflow of water, so as to expose the drainage pipeline, that is, the safety and stability of use are improved.

[0028] The rotation shaft seat 2 is provided with a limiting opening 10 on one side, and the cover plate 3 is provided with a limiting plate 11 on one side. The sum of the height of the limiting opening 10 and the thickness of the limiting plate 11 is equal to the height of the rotation shaft seat 2. That is, when the cover plate 3 is rotationally connected with the cover body 1 and is in a sealing state, the limiting opening 10 can limit the rotating position of the limiting plate 11, so that the cover plate 3 is sealed to a horizontal state. On the one hand, it is used for limiting the horizontal installation of the cover plate 3, and on the other hand, it is also used for positioning the clamping position of the anti-falling assembly 6 when the cover body 1 and the cover plate 3 are butted.

[0029] As shown in Figure 3 and Figure 4 The inside bottom of the cover body 1 is fixedly connected with ten locking ears 12 along the side wall, the anti-falling net 5 is placed between the top ends of the locking ears 12, the bottom surface of the anti-falling net 5 is fixedly connected with a positioning column 13 matched with each locking ear 12, and a nut 14 is arranged between the positioning column 13 and the matched locking ear 12;

[0030] The outer side surface of the anti-falling net 5 is vertically located inside the inner side wall of the adjacent side anti-falling assembly 6;

[0031] It should be noted that the anti-falling net 5 is installed inside the cover body 1 through the locking ear 12 and the positioning column 13, and the worker can replace the anti-falling net 5 by rotating the nut 14. After installation, when the cover plate 3 is opened by mistake, it can effectively prevent pedestrians and animals from falling into the inside of the pipeline, and improve the safety during anti-falling. In addition, since the outer side surface of the anti-falling net 5 is vertically located inside the top anti-falling assembly 6, the nut 14 can be conveniently replaced after the cover plate 3 is opened, so as to avoid the structural interference of the anti-falling assembly 6 when the anti-falling net 5 is replaced. Preferably, the anti-falling net 5 is a steel rope net, which is used to improve the bearing strength.

[0032] The anti-falling assembly 6 comprises an outer snap ring 61 fixedly connected to the inner side wall of the cover body 1, and an inner snap ring plate 62 fixedly connected to the inner side of the cover plate 3 at the top end of the outer snap ring 61, wherein the inner side of the outer snap ring 61 is convexly arc-shaped, and the outer side of the inner snap ring plate 62 is concavely arc-shaped;

[0033] It should be noted that the inner snap ring plate 62 is made of elastic steel, and when the cover plate 3 is capped, the inner snap ring plate 62 is clamped on the outer side of the inner snap ring plate 62 by means of the weight of the cover plate 3 and the impact kinetic energy when the cover plate 3 is closed, and the elastic force of the inner snap ring plate 62. When the cover plate 3 needs to be opened, the worker can pull the cover plate 3 up through the water hole 8 by means of the pull hook, that is, by means of the clamping position of the anti-falling assembly 6 limited by the limiting hole 10 and the clamping of the outer snap ring 61 and the inner snap ring plate 62, the limiting clamping between the cover body 1 and the cover plate 3 is realized, so as to improve the impact resistance of the cover plate 3 to the backflowing water flow.

[0034] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements within the scope of the present application should still belong to the patent coverage of the present application.
