Steel heat insulation fireproof door

Abstract

The invention belongs to the technical field of fireproof doors and particularly relates to a steel heat insulation fireproof door. The fireproof door comprises a door frame, a door plate, a water pumping unit, a water pipe and a sprayer, wherein the water pumping unit comprises a water pumping handle and a water pumping barrel; a side wall of the water pumping barrel is fixedly connected with a side wall of a groove; a top end of the pumping barrel and an upper end of the piston are fixedly connected with hinge blocks; holes are formed in the top of the pumping barrel; a drainage pipe communicated with the water pipe is arranged on one side of the water pumping barrel; the bottom of the water pumping barrel is communicated with an external water source; a water pumping handle is arranged on one side of the water pumping barrel away from the drain pipe; the water pumping unit enters the water pipe through the drainage pipe, water cools the door frame in the flowing process of the water pipe, the fireproof time of the fireproof door is prolonged, and then the survival time of trapped persons is prolonged; water is sprayed outwards through the sprayers arranged on the water pipes, the fireproof time of the fireproof door is prolonged through the water pumping unit under the condition of no electric drive, the survival time of trapped persons is further prolonged, and the survival rate of the trapped persons in a fire disaster is increased.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a steel heat insulation fire door. Background technique [0002] Fire is one of the most frequent and common major disasters that threaten public safety and social development. When a fire occurs, the fire door can play a certain role in blocking the fire and buy time for people to escape; when it is located in a high-rise building and cannot escape, it can give the trapped people certain protection; [0003] For example, Bulletin No. CN108894698B provides a thermal insulation, smoke-proof and fireproof door, which includes an outer door frame, an inner door frame, a door panel, a self-starting water circulation system, an exhaust system and a battery. , drive the smoke exhaust system and the water circulation system to exhaust the smoke and cool down, which increases the fire protection time of the fire door. However, in the actual use process, the battery encounters high te...

Problems solved by technology

[0003] For example, the announcement number CN108894698B provides a heat-insulated and smoke-insulated fire door, which includes an outer door frame, an inner door frame, a door panel, a self-opening water circulation system, an exhaust system, and a battery. Although in the process of a fire, the electricity stored in the battery , drive the smoke exhaust system and water circulation system to cool down the smoke exhaust and increase the fire protection time of the fire door. However, in the actual use process, the battery encounters high temperature, which will cause the battery to fail and fail to achieve the original technical effect. In severe cases, it may It will cause the explosion of the battery and aggravate the severity of the fire;
