Protective shell of radio frequency repeater device with heat dissipation assembly

Abstract

The invention relates to the field of radio frequency repeater devices, in particular to a protective shell of a radio frequency repeater device with a heat dissipation assembly, which comprises a base, a shell, a heat dissipation structure, an ash removal structure, a moving structure, a limiting structure, a protective structure and a fixed structure, through arrangement of the heat dissipationstructure, heat dissipation work can be fully carried out on electrical elements in the shell, electrical elements in the shell can be prevented from being damaged due to over-high temperature, whilethe heat dissipation structure works, the ash removal structure can be synchronously driven to work, the ash removal structure works, dust cleaning work can be carried out on the heat dissipation structure, the heat dissipation structure is prevented from being blocked by dust, through the arrangement of the moving structure, the moving assembly can be conveniently stretched out and stored, the moving structure can react to the fixing structure while working, through the arrangement of the fixing structure, the base and the ground can be stably fixed, and therefore the situation that the device slides in the working process can be avoided.

Description

technical field [0001] The invention relates to the field of radio frequency repeater devices, in particular to a protective shell of a radio frequency repeater device with a heat dissipation component. Background technique [0002] The repeater is composed of components or modules such as antenna, RF duplexer, low noise amplifier, mixer, electronically adjustable attenuator, filter, power amplifier, including uplink and downlink amplification links. The basic principle of its work is: use the forward antenna (donor antenna) to receive the downlink signal of the base station into the repeater, amplify the useful signal through the low-noise amplifier, suppress the noise signal in the signal, and improve the signal-to-noise ratio (S / N ); then down-converted to an intermediate frequency signal, filtered by a filter, amplified by an intermediate frequency, and then frequency-shifted and up-converted to a radio frequency, amplified by a power amplifier, and transmitted to the mo...

Problems solved by technology

[0003] Generally, a protective shell is installed on the outside of the RF repeater cabinet to protect the electrical components inside the repeater, but it will cause poor heat dissipation of the electrical components inside the repeater, and may even cause high temperat
