Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sealed doors, and particularly relates to a mine waterproof and fireproof sealed door. BACKGROUND

[0002] The mine waterproof and fireproof sealed door can effectively prevent the threat of fire and flood to the mine. In the event of a fire, these doors can block flames and high temperatures, preventing the spread of fire and protecting the safety of miners and mine equipment. In the event of a flood, the waterproof performance of the door can effectively prevent water flow from entering important areas, reducing the risk of damage to equipment and the mine. Such sealed doors, through strict sealing design, can ensure the integrity of the structure of the mine under harsh environmental conditions. This sealing not only prevents the external environment from invading the interior of the mine, but also helps to control the flow of gases inside the mine, maintaining the stability of the mine atmosphere. Since the door has waterproof and fireproof functions, it can greatly reduce the damage to equipment caused by environmental factors. Protecting the key equipment of the mine from the impact of fire and flood helps to extend its service life and reduce maintenance costs. The high-quality mine waterproof and fireproof sealed door is designed reasonably and easy to operate, and can be quickly closed or opened.

[0003] As disclosed in the publication No. CN214886613U, a protective fireproof sealed door is disclosed, which comprises a door frame and a sealed door.

A first connecting part is arranged in the groove. A fireproof cloth and a second connecting part are arranged in the door frame. One end of the fireproof cloth is fixed in the door frame, and the other end is fixedly connected with the second connecting part. When the sealed door closes the entrance and exit, the second connecting part drives the fireproof cloth to extend out of the door frame and is connected with the first connecting part. The application provides a protective fireproof sealed door, which can effectively prevent smoke from passing through the sealed door from the gap between the closed door and the door frame, block the dense smoke generated by burning, and improve the fireproof effect.
