AI Technical Summary

Technical Problem

Traditional tank manhole covers are difficult to operate in a compact space and cannot rotate simultaneously, affecting efficiency and increasing safety risks.

Method used

A side opening cover for tank body is designed, including a driving component, a sealing component and a limiting mechanism. Through the synergistic action of arc blocks, spur gears, external gears and threaded rods, the top cover is synchronously rotated and fixed. Integrated with airbag design ensures sealing and stability.

Benefits of technology

Improves operating efficiency and safety, avoids the complex process of manually rotating the bolts, ensures that the top cover is opened and closed smoothly in a limited space, enhances sealing performance and structural strength, and extends service life.

Abstract

The present invention relates to the technical field of manhole covers, and discloses a side-opening manhole cover for a tank body, comprising a base, a sealing mechanism is arranged on the top of the base, a limiting mechanism is arranged on the top of the sealing mechanism, the top of the base is fixedly connected to a limiting frame, a mounting mechanism is arranged inside the base, the sealing mechanism comprises a driving assembly and a sealing assembly, the driving assembly is arranged inside the sealing assembly, when in use, the driving assembly can be used to realize that when the manhole cover needs to be closed and fixed during use after the installation is completed, the threaded rod can be driven to rotate under the interaction of a rotating disk, a connecting frame, an external gear and a spur gear, so that the threaded rod can rotate synchronously, and the threaded rod is threadedly connected to the inside of the base, so that the top cover can be quickly fixed, thereby ensuring the stability of the top cover and the sealing between the top cover and the base, and avoiding the complicated and inefficient process of manually rotating bolts by staff.
