Abstract

The invention discloses a fire-fighting spray device for an anechoic chamber, which belongs to the technical field of electromagnetic compatibility. A connected shower head, the water receiving pipe includes an external pipe connected to the water source and a built-in pipe connected to the shower head, the external pipe is at the upper end of the ceiling, and the built-in pipe is vertically connected to the external pipe, And the outer layer of the built-in pipe is provided with an isolation component, and the lower end surface of the shower head is flush with the lower end of the wave absorbing device. The invention has the advantages of ensuring that the shielding body of the electric wave anechoic chamber has a good shielding effect, and at the same time it can also be used for fire fighting, so as to extinguish the fire in the electric wave chamber.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility, in particular to a darkroom fire sprinkler device. Background technique [0002] The anechoic chamber is mainly used to provide the standard environment required for electromagnetic compatibility testing, and is the most basic means to improve test consistency and repeatability. Traditionally, this environment can be accomplished by building an open test field. With the increase of space signals, it is difficult to obtain an open test field with a good background, so domestic and foreign standards recommend the use of an anechoic chamber to replace the open field. The anechoic chamber has gradually become the most widely used EMC testing site due to its stable electromagnetic environment, controllable temperature and humidity, and not being affected by the external climate. [0003] Due to the high cost of the anechoic chamber, the electromagnetic wave absorbing materials ...
