Problems solved by technology

Generally, a corresponding number of fire extinguishers will be placed according to the size of the anechoic chamber. However, since the common fire extinguishers are metal casings and large in size, if they are placed directly inside the anechoic chamber, it will have an impact on the sound field of the anechoic chamber.

Abstract

The invention relates to a dedicated wedge for fire protection equipment in an anechoic room. The wedge comprises a sound absorption wedge and multiple fire extinguishers, wherein a fire extinguisher placement box is disposed on the back end of the sound absorption wedge; the multiple fire extinguishers are placed in the fire extinguisher placement box; pulleys are installed on the bottom of the dedicated wedge; and a pull handle which facilitates pulling of the fire protection wedge is disposed on the tip end side of the sound absorption wedge. According to the invention, influences caused by external placement of the fire extinguishers on acoustic performance of the anechoic room can be avoided; an overall anechoic structure of the anechoic room is kept; the fire extinguisher placement box applies space of a cavity between the sound absorption wedge and a wall body, so the appearance is smooth and consistent; and the fire extinguishers can be fetched and used conveniently.

Description

technical field [0001] The invention belongs to the technical field of fire fighting in an anechoic chamber, and in particular relates to a special wedge for fire-fighting equipment in an anechoic chamber. Background technique [0002] According to the national standard "GB50800-2012 Technical Specifications for Anechoic Chambers and Semi-Anechoic Rooms" and "GB50016-2014 Code for Fire Protection Design of Buildings", fire extinguishers must be installed in the anechoic chambers. Generally, a corresponding number of fire extinguishers are placed according to the size of the anechoic chamber. However, since the common fire extinguishers are metal casings and large in size, if they are placed directly inside the anechoic chamber, the sound field of the anechoic chamber will be affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special wedge for fire-fighting equipment in the anechoic chamber, which can avo...
