Fast waterproof roller shutter door

Abstract

The invention discloses a fast waterproof roller shutter door, which comprises a door head, a door frame, a fireproof door roller shutter and expansion screw bolts, wherein a water supply pipe is arranged in the door head and the door frame; a plurality of sprayers are arranged on the water supply pipe; openings of the sprayers are projected out of the inner side edge of the door head and the door frame and are distributed to form a circle; a smoke detection sensing device is arranged on the outer surface of the door head. The fast waterproof roller shutter door has the advantages that the water supply pipe and the sprayers are arranged in the door head and the door frame; when smoke exists around the roller shutter door and reaches a certain quantity, the smoke detection sensing device detects the smoke and gives out signals, and a firefighting linkage system warns; the fireproof door roller shutter descends to a preset position; after personnel escape, the fireproof door roller shutter continuously descends to be closed, so that the inside and the outside are isolated; water flow with the water pressure being 5 to 8kg is generated in the water supply pipe; a water curtain is formed around the door head and the door frame through the spraying in the three directions; the high-temperature deformation of the roller shutter door is prevented.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a rapid fireproof rolling door. Background technique [0002] The development of fast rolling doors has been popularized in developed industrial countries such as Europe, America, and Japan for many years. Although it started late in China, it develops very fast, and it increases at a rate of about 40% every year. Fast rolling doors are used in a wide range, especially in production enterprises, there must be fast rolling doors between workshops, such as food and pharmaceutical companies, the government will mandate that fast rolling doors must be used for isolation, so as to prevent products from being damaged Secondary pollution, just like my country's mandatory regulations that certain industries must install fire doors, but the past fast rolling doors only have flame retardant components, but cannot achieve the real function of fire prevention, that is, they cannot meet ...
