Abstract

The invention relates to an anechoic chamber facilitating replacement of a wave-absorbing material and an installation method. The anechoic chamber comprises a chamber body, a first installation opening is formed in the top of the chamber body, the upper side of the first instalaltion opening is fixedly connected with a top bin, an installation plate is arranged in the top bin, a first wave-absorbing plate is arranged under the instalation plate, and two pairs of rope rings are fixedly connected to the two sides of the top of the installation plate respectively. A lifting mechanism is arrangedon the top bin, second installation openings are formed in the side walls on the two sides of the chamber body, the inner wall of each second instllation opening is fixedly connected with a pair of supports, a plurality of fixing rods are fixedly connected with the inner walls of the supports, the tail ends of the fixing rods are fixedly connected with clamping racks, and a second wave-absorbingplate is arranged between the two clamping racks. Threaded holes are formed in the two side walls of the clamping racks 10, bolts are connected in the threaded holes through threads, and side bins arefixedly connected with the outer walls of the second instalation openings. The anechoic chamber has the characteristics that the structural design is resonable, convenience is brought to disassemblyand installation, the stability is high, and the anechoic chamber is not prone to shaking.

Description

technical field [0001] The invention relates to the technical field of radio anechoic chambers, in particular to an anechoic chamber and an installation method for convenient replacement of wave-absorbing materials. Background technique [0002] The anechoic room is also called shielded dark room, or non-reflection shielded room, which is composed of electromagnetic shielding room and radio frequency absorbing material. An anechoic chamber with all six inner surfaces covered with absorbing materials is called a full anechoic chamber, which can simulate free space; an anechoic chamber with four inner surfaces and ceilings covered with absorbing materials, and the ground as a reflective surface is called a semi-anechoic chamber, which can simulate an open space. proving ground. The absorbing material in the anechoic chamber is composed of a single-layer ferrite sheet with a working frequency range of 30MHz to 1000MHz and a conical carbon-containing sponge absorbing material. ...
