Description
Technical Field
[0001] The utility model relates to the field of municipal pipeline manhole covers, in particular to a novel self-locking odor-proof manhole cover. Background Art
[0002] In the current urban infrastructure construction, manhole covers are usually composed of two parts: a sturdy and durable manhole ring and a cover body that fits tightly on it. This design ensures that the manhole cover can seamlessly connect with the surrounding road surface after installation, effectively avoiding safety hazards caused by height differences. At the same time, the basic function of the manhole cover is to block the intrusion of rainwater, fallen leaves and other debris, preventing them from falling into the well, thereby blocking the drainage system or causing other adverse effects.
[0003] However, traditional manhole covers still have many problems. In particular, the matching method between the rectangular protruding ring on the cover and the corresponding ring groove on the manhole ring can provide stability to a certain extent, but due to the connection method and material properties, there is often a problem of insufficient fixation. Since the manhole cover and the manhole ring are not tightly combined, gaps are likely to appear, which may cause the odor generated by the sewage and garbage accumulated in the well to leak out through the gaps, seriously affecting the quality of life of surrounding residents and urban environmental sanitation.
[0004] Therefore, the utility model proposes a new self-locking anti-odor manhole cover design scheme, which achieves a tight lock between the cover body and the manhole ring by introducing an advanced self-locking mechanism, significantly enhancing the stability and sealing of the manhole cover, while further compressing the gap between the cover body and the manhole ring, completely blocking the channel for odor leakage. Utility Model Content
[0005] In order to solve the above problems in the prior art, the utility model provides a novel self-locking odor-proof manhole cover, which enhances the odor-proof ability of the manhole cover by installing a sealing strip on the manhole cover and strengthening the connectivity between the manhole cover and the manhole ring.
[0006] In order to achieve the above-mentioned purpose, the solution provided by the utility model is: a new self-locking odor-proof manhole cover, including a manhole ring, a manhole cover is embedded in the inside of the manhole ring, the bottom of the manhole cover is embedded in the manhole cover bottom plate, triangular fixing blocks are provided at the four corners on the inner side of the manhole cover, mounting holes are provided on the triangular fixing blocks, mounting holes are provided in the mounting holes, and mounting nails are provided in the mounting holes, and the mounting nails are provided with a cylindrical nail body and a mounting nail cap.
[0007] As a further improvement of the utility model, the manhole ring is a profile with an L-shaped cross section, and a hollow square hollow groove is provided at the bottom of the manhole ring; and a transverse fixing groove is provided on the side of the manhole ring. By using the L-shaped profile to construct the manhole ring body, the weight of the manhole cover can be reduced while ensuring the strength of the manhole ring, and the pressure at the bottom of the manhole ring can be eliminated through the square hollow groove, thereby enhancing the durability and stability of the manhole ring.
[0008] As a further improvement of the present utility model, a cylindrical groove is provided on the upper surface of the well ring bottom. The cylindrical groove is arranged annularly along the upper surface of the well ring bottom. A buffer seal is installed in the cylindrical groove. By setting the buffer seal, the sealing effect between the manhole cover and the well ring can be further enhanced, preventing odor and sewage from leaking out through the gap between the well ring and the manhole cover, and increasing the buffering between the manhole cover and the well ring during installation, preventing damage to the manhole cover or the well ring.
[0009] As a further improvement of the present utility model, an installation bayonet is provided on the inner wall of the side surface of the well ring. A manhole cover sealing strip is embedded in the installation bayonet. By using the manhole cover sealing strip and the buckle, the sealing performance and friction between the well ring and the manhole cover can be enhanced, preventing the manhole cover from slipping off the well ring, and effectively enhancing the sealing performance of the manhole cover, improving the safety performance of the new self-locking anti-odor manhole cover.
[0010] As a further improvement of the present utility model, a strengthening network is provided on the upper surface of the manhole cover. By setting the strengthening network, the strength and load-bearing capacity of the manhole cover are improved, avoiding the problem of extrusion deformation caused by the overweight of the manhole cover.
[0011] As a further improvement of the present utility model, the strengthening network is composed of reinforcing ribs connected in a grid shape. By using the grid-shaped reinforcing ribs, the pressure can be more evenly dispersed, improving the durability and stability of the manhole cover.
[0012] As a further improvement of the present utility model, an installation thread layer is provided in the installation hole. By setting the installation thread layer in the installation hole, the installation nails can be more firmly fixed on the manhole cover, thereby further enhancing the stability and anti-theft performance of the manhole cover.
[0013] As a further improvement of the present utility model, the manhole cover is a cover plate with an L-shaped cross-section. A manhole cover bottom plate slot is provided at the bottom of the manhole cover. A self-locking fixing structure is provided at the upper end of the manhole cover. The self-locking fixing structure is self-locked with the sealing strip. By using the self-locking fixing structure to perform self-locking connection with the well ring, the stability of the manhole cover structure is enhanced.
[0014] The beneficial effects of the present utility model are:
[0015] 1. By using the self-locking connection between the well ring and the manhole cover composed of L-shaped profiles, and limiting the installation and fixing position of the manhole cover through the triangular fixing block and the installation nails, the problems of easy displacement and insufficient self-strength of the manhole cover in the prior art are solved, achieving the beneficial effects of enhancing the stability and firmness of the manhole cover structure installation and increasing the portability of the manhole cover use.
[0016] 2. By setting a manhole cover sealing strip between the side surfaces of the manhole cover and the manhole ring, and a buffer strip between the bottom of the manhole cover and the upper surface of the manhole ring, the sealing performance of the new self-locking anti-odor manhole cover is enhanced, effectively avoiding the leakage of sewage and odor, and enhancing the anti-pollution and anti-odor capabilities of the manhole cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will describe in detail the specific embodiments of the present utility model. It should be noted that the embodiments described here are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
[0023] The first embodiment of the present utility model provides a new self-locking anti-odor manhole cover, including a manhole ring 1. A manhole cover 2 is fitted and connected inside the manhole ring 1. A manhole cover bottom plate 3 is embedded at the bottom of the manhole cover 2. Triangular fixing blocks 4 are provided at the four corners inside the manhole cover 2. Installation holes 5 are provided on the triangular fixing blocks 4, and installation nails 6 are provided in the installation holes 5. The installation nails 6 are provided with cylindrical nail bodies and installation nail caps. The manhole cover bottom plate 3 is embedded at the bottom of the manhole cover 2. The manhole cover bottom plate 3 is a flat plate, which can prevent sewage and odor from surging up through the manhole cover 2. The triangular fixing blocks 4 are fixedly connected to the four corners inside the manhole cover 2. The triangular fixing blocks 4 can reinforce the structure of the manhole cover. By installing the cylindrical nail bodies of the installation nails 6 into the triangular fixing blocks 4, the manhole cover 2 can be fixedly connected to the manhole ring 1, thereby avoiding the problem of loosening of the manhole cover 2 caused by displacement and sliding of the manhole cover 2. The installation nail caps are arranged at the tops of the cylindrical nail bodies, facilitating the removal of the installation nails 6.
[0024] In this embodiment, the well ring 1 is a profile with an L-shaped cross-section. The well ring 1 is a square ring structure with openings at both the top and bottom. A hollow square groove 7 is provided at the bottom of the well ring 1, and several hollow grooves are provided on the bottom surface of the well ring 1. The fixed grooves provided on the side surface of the well ring 1 can enhance the friction and adsorption force between the well ring 1 and the ground soil. Thus, when the well ring 1 is installed underground, it can be more firmly fixed, enhancing the stability of the manhole cover 2. By using an L-shaped profile to build the body structure of the well ring 1, while ensuring the strength of the well ring 1, the weight of the manhole cover 2 can be reduced, and the pressure at the bottom of the well ring 1 can be relieved through the square hollow groove 7, enhancing the durability and stability of the well ring 1. By using an L-shaped cross-section well ring 1 with a hollow square groove 7, a cylindrical groove is provided on its upper surface, and a buffer seal 8 is embedded in the cylindrical groove. The buffer strip is arranged in a ring shape on the bottom surface of the well ring 1. The buffer seal 8 can enhance the friction between the manhole cover 2 and the well ring 1, thereby enhancing the grasping force between the manhole cover 2 and the well ring 1, making the connection between the manhole cover 2 and the well ring 1 more firm. Moreover, by setting the buffer seal 8, the sealing effect between the manhole cover 2 and the well ring 1 can be further enhanced, preventing odors and sewage from leaking out through the gap between the well ring 1 and the manhole cover 2, and increasing the buffering performance between the manhole cover 2 and the well ring 1 during installation, preventing damage to the manhole cover 2 or the well ring 1.
[0025] In this embodiment, an installation bayonet is provided on the inner wall of the side surface of the well ring 1. The installation bayonet is located at a position close to the top on the inner wall of the side surface of the well ring 1 and is a groove distributed in a ring shape along the inner wall of the side surface of the well ring 1. A manhole cover sealing strip 9 is embedded in the installation bayonet. When the manhole cover 2 is placed on the manhole cover sealing strip 9, a sealing structure of the manhole cover 2 is formed between the manhole cover sealing strip 9 and the manhole cover 2. By using the manhole cover sealing strip 9 and the bayonet, the sealing performance and friction between the well ring 1 and the manhole cover 2 can be enhanced, preventing the manhole cover 2 from slipping out of the well ring 1, and effectively enhancing the sealing performance of the manhole cover 2, improving the installation reliability of the new self-locking anti-odor manhole cover 2, thereby improving the safety performance of the manhole cover 2.
[0026] In this embodiment, a strengthening network 10 is provided on the upper surface of the manhole cover 2. By setting the strengthening network 10, the strength and load-bearing capacity of the manhole cover 2 are improved, avoiding the problem of extrusion deformation caused by the excessive weight of the manhole cover 2. The strengthening network 10 is a reinforcing rib connected in a grid shape. By using the grid-shaped reinforcing rib, the pressure can be more evenly distributed, improving the durability and stability of the manhole cover 2. The reinforcing ribs are combined and linked vertically and horizontally to form a stable well-shaped reinforcing rib network. The two ends of the reinforcing rib network are inserted into the inner wall side of the manhole cover 2, thereby enhancing the strength and load-bearing capacity of the manhole cover 2.
[0027] In this embodiment, an installation thread layer is provided in the installation hole 5, and the threads of the installation thread layer match the threads of the installation nail 6. The installation nail 6 can be inserted into the installation hole 5 of the triangular fixing block 4 in a spiral knob manner, increasing the connection strength between the triangular fixing block 4 and the manhole cover 2. By providing the installation thread layer in the installation hole 5, the installation nail 6 can be more firmly fixed on the manhole cover 2, thereby further enhancing the stability and anti-theft performance of the manhole cover 2.
[0028] In this embodiment, the manhole cover 2 is a cover plate with an L-shaped cross-section. A slot for the manhole cover bottom plate 3 is provided at the bottom of the manhole cover 2. The groove of the manhole cover bottom plate 3 is a narrow and long U-shaped groove. The manhole cover bottom plate 3 is embedded in the groove of the manhole cover bottom plate 3 to form a complete structure of the manhole cover 2. A self-locking fixing structure 11 is provided at the upper end of the manhole cover 2. The side wall of the manhole cover 2 turns outward and extends out the self-locking fixing structure 11. The self-locking fixing structure 11 is self-locked with the sealing strip. By using the self-locking fixing structure 11 to perform self-locking connection with the manhole ring 1, after the manhole cover 2 is self-locked, the self-locking between the manhole cover 2 and the manhole ring 1 enhances the stability of the structure of the manhole cover 2.
[0029] A novel self-locking anti-odor manhole cover proposed in this embodiment solves the problems of easy displacement and insufficient self-strength of the manhole cover in the prior art by using a self-locking connection between the manhole ring and the manhole cover composed of L-shaped profiles and defining the installation and fixing positions of the manhole cover through triangular fixing blocks and installation nails, achieving the beneficial effects of enhancing the stability and firmness of the manhole cover structure installation and increasing the portability of the manhole cover. Moreover, the novel self-locking anti-odor manhole cover enhances the sealing performance of the novel self-locking anti-odor manhole cover and effectively avoids the leakage of sewage and odor by providing a manhole cover sealing strip between the side surfaces of the manhole cover and the manhole ring and a buffer strip between the bottom of the manhole cover and the upper surface of the manhole ring, enhancing the anti-pollution and anti-odor capabilities of the manhole cover.
