Description

Technical Field

[0001] The utility model relates to the technical field of road safety protection, in particular to an inspection well for municipal drainage. Background Art

[0002] In the city, all public water supply, sewage, telephone lines, and fiber optic networks may be connected through underground passages under inspection wells. Inspection wells are their exits to the ground and are covered by inspection well covers. Most underground pipelines are straight. When a turn is required, inspection wells are set at the turning position to prevent the straight pipeline from being blocked and to facilitate the installation of pipelines. In addition, for the convenience of work and safety, inspection wells are set up in the middle of a certain length of pipeline to facilitate entry and exit of the pipeline.

[0003] At night, on rainy days, etc., due to the dark vision, once the manhole cover is lost or washed away, and there are no protective measures on the manhole, it is very easy for pedestrians or objects to fall into the manhole, causing pedestrians to fall into the manhole and get injured or even endanger their lives. To solve this problem, the prior art usually installs a protective net in the well, and the protective net is fixed by hooks or perforations (such as the patent with publication number CN207405658U). Although such a structure can solve the fall prevention problem to a certain extent, due to the low strength of the connecting parts such as the hook, it is easy to deform or even break under strong impact and the hook is subjected to shear force, which causes the protective net to detach from the hook; at the same time, when the hook is fixed to the wall of the manhole, it is necessary to drill a hole. Due to the limited working space, drilling is difficult and the drilling process is time-consuming and laborious. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a municipal drainage inspection well, in which the protective net is detachably connected to the well wall through the first wedge block and the second wedge block, and the protective net is subjected to a downward force, which acts on the first wedge block through the second wedge block, and the second wedge block transfers the force to the well wall. In the process of increasing force, the second wedge block is squeezed by the first wedge block, so the second wedge block is not easy to deform or separate from the well wall. At the same time, the wedge block is integrated with the well wall, and when the protective net is installed, only simple alignment and lowering operations are required, without the need for on-site construction.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] An inspection well for municipal drainage comprises a well body and a well cover arranged at the top of the well body, wherein a protective net is also arranged in the well body, and the protective net is fixed in the well body through a connecting piece;

[0007] The connecting member includes multiple first wedge blocks and multiple second wedge blocks; the multiple first wedge blocks are evenly distributed on the inner wall of the well body or the inner wall of the edge ring of the well cover, and the multiple second wedge blocks are evenly distributed at the bottom edge of the protective net and are arranged corresponding to the first wedge blocks.

[0008] Furthermore, the first wedge block is provided with a slide groove along its inclined surface, and the second wedge block is arranged in the slide groove.

[0009] Furthermore, the first wedge block is arranged on the inner wall of the well body, and the first wedge block and the inner wall of the well body are an integrated structure.

[0010] Furthermore, the first wedge-shaped block is arranged on the inner wall of the edge ring of the manhole cover, and the first wedge-shaped block and the edge ring of the manhole cover are an integrated structure.

[0011] Furthermore, the protective net is an integrated grid-like circular plate structure.

[0012] Furthermore, the protective net includes a connecting ring plate and a rope net arranged on the inner circle of the connecting ring plate, and the second wedge block is arranged at the bottom of the connecting ring plate.

[0013] The beneficial effects of the utility model are:

[0014] The protective net of the utility model is detachably connected to the well wall through the first wedge block and the second wedge block. The protective net is subjected to a downward force, which acts on the first wedge block through the second wedge block, and the second wedge block transfers the force to the well wall. In the process of increasing force, the second wedge block is squeezed by the first wedge block, so the second wedge block is not easy to deform or separate from the well wall. At the same time, the wedge block is integrated with the well wall, so when installing the protective net, only simple alignment and lowering operations are required, and no on-site construction is required.

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0022] Embodiment 1:

[0023] like Figure 1-Figure 4 As shown, a municipal drainage inspection well comprises a well body 1 and a well cover 2 arranged at the top of the well body 1, wherein a protective net 3 is also arranged in the well body 1, and the protective net 3 is fixed in the well body 1 through a connecting piece 4;

[0024] The connecting member 4 includes a plurality of first wedge blocks 5 and a plurality of second wedge blocks 6; the plurality of first wedge blocks 5 are evenly distributed on the inner wall of the well body 1 or the inner wall of the edge ring 7 of the well cover 2, and the plurality of second wedge blocks 6 are evenly distributed at the bottom edge of the protective net 3 and are arranged corresponding to the first wedge blocks 5.

[0025] The first wedge block 5 is provided with a slide groove 8 along its inclined surface, and the second wedge block 6 is arranged in the slide groove 8. The slide groove 8 cooperates with the second wedge block 6 to prevent the protective net 3 from rotating in the circumferential direction.

[0026] The first wedge block 5 is arranged on the inner wall of the edge ring 7 of the manhole cover 2, and the first wedge block 5 and the edge ring 7 of the manhole cover 2 are an integrated structure. The first wedge block 5 is integrally cast with the edge ring 7 when the manhole cover 2 (edge ​​ring 7) is cast.

[0027] The protection net 3 includes a connecting ring plate 8 and a rope net 9 arranged on the inner circle of the connecting ring plate 8, and the second wedge block 6 is arranged at the bottom of the connecting ring plate 8. Such an arrangement can prevent the falling object from hard contact with the protection net 3 when falling occurs, causing secondary damage to the falling object.

[0028] Working principle: Before closing the manhole cover 2, align the second wedge block 6 at the bottom of the protection net 3 with the chute 8 on the first wedge block 5 so that the two can fit together. The protection net 3 is stably supported in the well body 1 by the first wedge block 5 and the second wedge block 6. The chute 8 can prevent the protection net 3 from rotating in the circumferential direction and causing the first wedge block 5 to separate from the second wedge block 6.

[0029] When a fall occurs, the protection net 3 tends to move downward, but the presence of the first wedge block 5 and the second wedge block 6 can prevent the protection net 3 from moving downward.

[0030] At the same time, the protective net 3 is subjected to a downward force, which acts on the first wedge block 5 through the second wedge block 6, and the second wedge block 6 transmits the force to the well wall. During the process of increasing force, the second wedge block 6 is squeezed by the first wedge block 5, so the second wedge block 6 is not easy to deform or separate from the well wall. At the same time, the wedge block is integrated with the well wall, so when installing the protective net 3, only simple alignment and lowering operations are required, and no on-site construction is required.

[0031] The protective net 3 of the utility model is detachably connected to the well wall through the first wedge block 5 and the second wedge block 6. The protective net 3 is subjected to a downward force, which acts on the first wedge block 5 through the second wedge block 6, and the second wedge block 6 transmits the force to the well wall. In the process of increasing force, the second wedge block 6 is squeezed by the first wedge block 5, so the second wedge block 6 is not easy to deform or separate from the well wall. At the same time, the wedge block is integrated with the well wall. When the protective net 3 is installed, only simple alignment and lowering operations are required, and no on-site construction is required.

[0032] Embodiment 2:

[0033] The difference between this embodiment and embodiment 1 is that the first wedge block 5 is arranged on the inner wall of the well body 1, and the first wedge block 5 and the inner wall of the well body 1 are an integrated structure. The protection net 3 is an integrated grid-shaped circular plate structure.

[0034] The first wedge-shaped block is arranged on the inner wall of the well body and is integrally formed with the inner wall of the well body during casting.

[0035] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
