[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0033] Example: Figure 1-5 As shown, the utility model provides a technical solution, a pressure-resistant artistic manhole cover, comprising a manhole cover body 1, and a bottom dynamic support mechanism 2 is provided at the bottom of the manhole cover body 1;

[0034] The bottom dynamic support mechanism 2 includes a clamping top ring 201, a clamping bottom ring 202, a mounting side seat 203, a support bend 204, an anti-slip side groove 205, a support arc rod 206 and a central support box 207;

[0035] The bottom edge of the manhole cover body 1 is fixedly installed with a clamping top ring 201, and the bottom surface of the clamping top ring 201 is clamped with a clamping bottom ring 202. The bottom edge of the clamping bottom ring 202 is evenly and evenly fixedly connected with a mounting side seat 203 in the circumferential direction. A supporting bent block 204 is rotatably installed in the middle of the bottom end of the mounting side seat 203 through a rotating shaft. The arc surface of the end of the supporting bent block 204 is evenly and evenly provided with anti-slip side grooves 205. The top of the inner side of the supporting bent block 204 is fixedly connected with a supporting arc rod 206, and the ends of multiple supporting arc rods 206 are fixedly connected with a central support box 207. The groove on the bottom surface of the clamping top ring 201 and the convex block on the top surface of the clamping bottom ring 202 fit tightly. The outer arc surface of the supporting bent block 204 has the same shape as the arc surface of the edge of the manhole cover body 1. The mounting side seat 203 and the components at its bottom are installed to the bottom of the manhole cover body 1 by cooperating with each other. When the top of the manhole cover body 1 is under pressure, the pressure on the manhole cover body 1 is transmitted downwardly through the central support box 207. The downward movement of the central support box 207 drives the supporting arc rod 206 to swing downward. Then, the mutual cooperation between the mounting side seat 203 and the supporting arc rod 206 drives the supporting bent block 204 to swing outward. During the swinging process of the supporting bent block 204, it fits tightly with the well wall. The friction between the supporting bent block 204 and the well wall is increased by the anti-slip edge groove 205. Then, the bottom of the manhole cover body 1 is auxiliary supported by the supporting bent block 204, the supporting arc rod 206 and the central support box 207, thereby effectively improving the overall pressure resistance of the manhole cover.

[0036] A central support adjustment mechanism 3 is provided inside the central support box 207;

[0038] A mounting threaded hole 301 is provided through the middle of the bottom surface of the center support box 207, and an adjusting threaded rod 302 is inserted through the middle of the inner side of the mounting threaded hole 301 through a thread, and the top of the adjusting threaded rod 302 is connected to the supporting top plate 303 at the internal position of the center support box 207, and an adjusting hexagonal hole 304 is provided in the middle of the top surface of the supporting top plate 303. The bottom end of the adjusting threaded rod 302 is fixedly connected to the limiting circular plate 305 at the position corresponding to the bottom surface of the center support box 207, and the limiting small column 306 is symmetrically embedded in the middle of the bottom surface of the center support box 207. An adjusting top hole 307 is provided through the middle of the top of the manhole cover main body 1, and the top surface of the supporting top plate 303 is tightly fitted with the bottom surface of the manhole cover main body 1. The positions of the adjusting hexagonal hole 304 and the adjusting top hole 307 correspond to each other. The adjusting threaded rod 302 and The components thereon are installed inside the central support box 207. When the middle of the manhole cover body 1 needs to be adjusted and shaped, the wrench is inserted into the adjusting hexagonal hole 304 through the adjusting top hole 307. Then, the adjusting threaded rod 302 is driven to rotate along the inside of the mounting threaded hole 301 through the cooperation between the wrench and the adjusting hexagonal hole 304. During the rotation of the adjusting threaded rod 302, the supporting top plate 303 is driven to move upward in the vertical direction. Then, the top depression of the manhole cover body 1 is pushed upward by the squeezing of the supporting top plate 303, thereby realizing the shaping of the whole manhole cover body 1. At the same time, the movement range of the adjusting threaded rod 302 is limited by the limiting circular plate 305 and the limiting small column 306, thereby preventing the manhole cover body 1 from being damaged due to excessive deformation range, thereby effectively improving the convenience of use of the manhole cover body 1.

[0039] An edge elastic collecting mechanism 4 is provided on the bottom edge of the manhole cover body 1;

[0040] The edge elastic collecting mechanism 4 includes an inner mounting ring 401, a hard mounting ring 402, a filtering ring net 403 and a limiting soft ring 404;

[0041] The inner ring 401 is bonded to the inner ring of the bottom surface of the manhole cover body 1, and the top of the outer side of the inner ring 401 is fixedly connected with a mounting hard ring 402. The bottom of the outer side of the mounting hard ring 402 is fixedly sleeved with a filter ring net 403, and the top of the outer side of the filter ring net 403 is fixedly bonded with a limiting soft ring 404. The mounting hard ring 402 and the limiting soft ring 404 are tightly fitted to the bottom surface of the manhole cover body 1, and the filter ring net 403 and the limiting soft ring 404 can be elastically deformed. By installing the inner ring 401 and the components thereon, the manhole cover body 1 is installed to the manhole cover body 1. At the bottom of the cover body 1, the shape of the filter ring net 403 is maintained by installing a hard ring 402, and then the sewage entering the inside of the manhole cover body 1 is filtered through the filter ring net 403 to intercept impurities in the sewage, and the edge of the filter ring net 403 is limited by the limiting soft ring 404 to prevent impurities in the sewage from falling from the edge of the filter ring net 403, and the elastic structure design of the filter ring net 403 and the limiting soft ring 404 makes it easier to clean the impurities on the top of the filter ring net 403.

[0042] Working principle and use process of the present invention: During the use of the manhole cover, the mounting side seat 203 and the components at its bottom are mounted to the bottom of the manhole cover body 1 through the mutual cooperation between the clamping top ring 201 and the clamping bottom ring 202. When the top of the manhole cover body 1 is under pressure, the pressure on the manhole cover body 1 is transmitted downward through the central support box 207, and the downward movement of the central support box 207 drives the supporting arc rod 206 to swing downward;

[0043] Then, the supporting block 204 is driven to swing outward by the cooperation between the mounting side seat 203 and the supporting arc rod 206. During the swinging process, the supporting block 204 is closely fitted with the well wall. The anti-slip side groove 205 increases the friction between the supporting block 204 and the well wall. Then, the supporting block 204, the supporting arc rod 206 and the central support box 207 provide auxiliary support for the bottom of the manhole cover body 1, thereby effectively improving the overall pressure resistance of the manhole cover.

[0044] When a slight concave deformation occurs at the center of the manhole cover body 1 for a long time, the adjusting threaded rod 302 and the components thereon are installed into the center support box 207 through the installation threaded hole 301. When it is necessary to adjust and shape the middle part of the manhole cover body 1, the wrench is inserted into the adjusting hexagonal hole 304 through the adjustment top hole 307. Then, the adjusting threaded rod 302 is driven to rotate along the installation threaded hole 301 through the cooperation between the wrench and the adjustment hexagonal hole 304. During the rotation of the adjusting threaded rod 302, the supporting top plate 303 is driven to move upward in the vertical direction. Then, the top depression of the manhole cover body 1 is pushed upward by the squeezing of the supporting top plate 303, thereby realizing the shaping of the entire manhole cover body 1.

[0045] At the same time, the limiting circular plate 305 and the limiting small column 306 limit the movement range of the adjusting threaded rod 302, preventing the manhole cover body 1 from being damaged due to excessive deformation, thereby effectively improving the convenience of use of the manhole cover body 1;

[0046] When it is necessary to filter the sewage that passes through the manhole cover body 1 and enters the sewer, the inner ring 401 and the components thereon are installed on the bottom of the manhole cover body 1, and the shape of the filter ring net 403 is maintained by installing the hard ring 402. Then, the sewage entering the inside of the manhole cover body 1 is filtered through the filter ring net 403 to intercept impurities in the sewage, and the edge of the filter ring net 403 is limited by the limiting soft ring 404 to prevent impurities in the sewage from falling from the edge of the filter ring net 403. The elastic structure design of the filter ring net 403 and the limiting soft ring 404 makes it easier to clean the impurities on the top of the filter ring net 403.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
