A High-Protection Civil Defense Door

Abstract

The invention discloses a civil air defense door with high protection performance. The top and bottom of both sides of the installation door frame are welded with installation special-shaped blocks. A heat-absorbing box is installed, and the top of one side of the heat-absorbing box is fixedly connected with an ascending conduit, and one end of the ascending conduit is fixedly connected with a regulating fluid tank at the position corresponding to the top of the door frame, and the middle part of the top of the regulating fluid tank is fixedly connected with a buffer tank, the invention absorbs the heat outside the main body of the protective door through the coolant inside the heat-absorbing box, guides the high-temperature coolant into the cooling box for cooling through the cooling conduits on both sides of the regulating liquid tank, and cools the high-temperature coolant through the cooling box For cooling, the cooled low-temperature coolant is reintroduced from the bottom of the heat-absorbing box through the liquid return pipe, which effectively prevents the heat from the outside of the main body of the protective door from being transferred to the interior of the room, and improves the protective effect of the civil air defense door.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to a high protective performance civil air defense door. Background technique [0002] Civil defense is also called civil defense. Civil defense is an international term. It is an activity in which the government mobilizes and organizes the masses, takes anti-airstrike, disaster relief measures, implements rescue operations, prevents and mitigates disaster hazards. Civil defense doors need to use hydraulic pressure in the production process. molding device; [0003] However, due to the lack of a corresponding cooling mechanism for civil air defense doors currently on the market, the high temperature on the outside of the civil air defense door easily penetrates the civil air defense door and is transmitted to the inside, thereby reducing the protective performance of the civil air defense door and making it unable to effectively protect against high temperatures;...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a high-protection civil air defense door, which can effectively solve the problem that the civil air defense door proposed in the above background technology lacks a corresponding cooling mechanism, causing the high temperature on the outside of the civil air defense door to easily pass through the civil air defense door and transfer to the inside, thereby reducing the air defense door. In the process of processing civil air defense door components through the hydroforming device, due to the lack of corresponding anti-clogging mechanism of the hydroforming device, the hydraulic forming device causes the material guide pipe to be damaged after the die-casting is completed. Solidified raw materials are easy to remain inside, causing clogging of the die-casting mold and reducing the performance of the hydroforming device
