In the field construction process of the box body device, the inside of the box body device needs to be ventilated through a manhole to ensure the life safety of workers, the ventilation measure of the manhole at present is to directly fix a plastic film air pipe inside the box body, so that the workers are inconvenient to enter and exit, an effective closed area cannot be formed at the manhole, the air pressure loss is serious, and the ventilation effect in the box body is influenced; meanwhile, as no special fixing device is arranged in the box body, the air pipe is damaged quickly and is easy to separate from the box body, and potential safety hazards are formed.
Disclosure of Invention
The utility model aims to solve the problems of the existing construction manhole of a box body and provides a manhole cover device.
The technical solution of the utility model is as follows: a ventilation manhole cover device structurally comprises a base, a manhole cover, a magnetic suction device and a hinge; wherein one side of the manhole cover is arranged on the upper surface of the base through 1 pair of hinges, and the magnetic attraction device is arranged on the other side of the manhole cover.
Furthermore, a waist-shaped hole is formed in the center of the base, and 4 screw holes are symmetrically formed in the periphery of the waist-shaped hole.
Furthermore, the whole manhole cover is in an oblong shape, the size of the whole manhole cover is slightly larger than a waist-shaped hole in the center of the base, and a circular vent hole is formed in the center of the manhole cover; one side of the manhole cover is provided with 1 pair of hinges, and the other side is provided with a bulge for installing a magnetic attraction device.
Furthermore, the magnetic attraction device adopts strong magnets.
Compared with the prior art, the utility model has the advantages that:
1) the original manhole base of a steel structure is utilized, a hinge and a magnetic suction device are adopted to assist in fixing the manhole cover, and meanwhile, the manhole cover is quickly opened and closed, so that people can conveniently go in and out;
2) through the design of special tuber pipe fixing device, it is more convenient to make plastic film tuber pipe installation, is difficult for causing the tuber pipe to damage, guarantees the ventilation effect, has solved the potential safety hazard in plastic film person's hole that drops, has guaranteed the safety of site operation.
