[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 This utility model provides a technical solution: a prefabricated manhole cover with strong sealing properties. In today's urban infrastructure, manhole covers are a crucial component of road safety, and their design and manufacturing quality are directly related to the safety of pedestrians and vehicles. To further enhance the sealing and durability of manhole covers, we have innovatively introduced a prefabricated manhole cover with strong sealing properties. This utility model not only comprehensively upgrades traditional manhole covers but also incorporates multiple advanced technologies to ensure its stable performance in various harsh environments.

[0026] The core components of the prefabricated manhole cover system

[0027] This prefabricated manhole cover primarily consists of a fixed cover body 1, the cornerstone of the entire system. A carefully designed mounting slot 2 sits on the upper side of the fixed cover body 1, cleverly blending aesthetics and practicality for both aesthetic appeal and ease of subsequent installation and maintenance. Within the mounting slot 2, two high-strength hinges 3 are specially designed to act as the cover's "steel backbone," ensuring its stability and durability. These two high-strength hinges 3, positioned adjacent and side-by-side, form a robust support structure that effectively resists external pressure and impact.

[0028] Innovation in strengthening cover and sealing design

[0029] A reinforcing cover plate 4 is cleverly installed above the high-strength hinge 3, significantly enhancing the manhole cover's load-bearing capacity. A sealing gasket 5 is specially installed at the junction of the reinforcing cover plate 4 and the mounting slot 2. This detailed treatment ensures a perfect seal when the manhole cover is closed, effectively preventing liquids such as rainwater and sewage from seeping into the underground pipes and protecting the normal operation of the urban drainage system. The sealing gasket 5 is also carefully selected, using high-quality waterproof materials to ensure its excellent sealing performance over long-term use.

[0030] Flexible connection and convenient opening

[0031] To facilitate the opening and closing of the manhole cover, a fixing base 6 is provided at the lower end of the reinforced cover plate 4, to which a connecting iron rod 7 is hinged. This design allows the manhole cover to rotate smoothly when opened, reducing operational difficulty and safety hazards. At the same time, to further enhance the stability of the manhole cover, a slot 8 is provided on the fixed cover body 1, into which a magnet 9 is inserted. The magnet 9 forms a magnetic connection with the connecting iron rod 7. This design not only enhances the stability of the manhole cover, but also allows the manhole cover to automatically adsorb to a fixed position when closed, reducing the tedious manual operation.

[0032] During the design of the manhole cover, we paid special attention to detail. For example, the upper side of the fixed cover body 1 features an elliptical handle groove 10, which houses a handle 11. This design allows workers to easily grip the cover when opening it, improving both efficiency and safety. Furthermore, a suspension spring 12 is installed between the connecting rod 7 and the reinforcing cover plate 4. This design effectively mitigates the impact of the manhole cover during opening, extending its service life.

[0033] Limit design that emphasizes both safety and convenience

[0034] In order to ensure the stability of the magnet 9 in the slot 8, we set a limiting ring 13 at the upper end of the magnet 9. The limiting ring 13 is not only stuck inside the slot 8, but also prevents the magnet 9 from falling off through its unique structural design. At the same time, a pinching plate 14 is fixed to the upper end of the limiting ring 13. This design allows the staff to easily apply force when removing the magnet 9, improving the convenience of operation. In addition, in order to further improve the sealing performance, we set a sealing layer 15 on the upper and lower side walls of the limiting ring 13. This detailed treatment ensures a close fit between the magnet 9 and the slot 8, effectively preventing the intrusion of water vapor and impurities.

[0035] In summary, this highly airtight prefabricated manhole cover system has won widespread market acclaim for its innovative design, sophisticated craftsmanship, and exceptional practical performance. It not only provides strong support for urban infrastructure development but also effectively safeguards pedestrian and vehicle safety. In the future, we will continue to uphold our corporate philosophy of "innovation, quality, and service" and continuously launch more high-quality products to meet market demand.
