Electronic information anti-interference device

Abstract

The invention discloses an electronic information anti-interference device, comprising an electronic information anti-interference main body, wherein two heat dissipation holes are formed in both sides of the electronic information anti-interference main body, and an air suction fan and an exhaust fan are fixedly connected to an inner wall of the electronic information anti-interference main bodythrough the heat dissipation holes. According to the electronic information anti-interference device disclosed by the invention, the air suction fan and the exhaust fan are provided through the heat dissipation holes, blades in the air suction fan and the exhaust fan rotate to drive a fixing rod, a connecting rod and meshing teeth to rotate, a rotating cylinder is rotationally connected to the both sides of the electronic information anti-interference main body through a limiting plate, a threaded rod and a roller, the rotating cylinder covers the heat dissipation holes through a dustproof net, the meshing teeth rotate for a circle with the connecting rod to engage with an annular gear rack for a segment of distance, thereby driving the annular gear rack to rotate for a certain angle, therefore the air suction fan sucks the air, then the position where the dust is adsorbed on the dustproof net is moved to the exhaust fan for exhausting to remove the dust, and accordingly, the effect ofpreventing the dustproof net from being blocked by the dust after long term use is achieved while implementing heat dissipation.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to an anti-jamming device for electronic information. Background technique [0002] The anti-interference device is the best auxiliary tool to solve the interference problems in the operation of the equipment. At present, there are two main methods of anti-jamming devices: one is the amplified anti-jamming method. In principle, this kind of anti-jamming device cannot eliminate interference, but it can effectively reduce the amplitude of interference signals; the other is frequency shifting. Anti-jamming method, this method can better solve the interference, therefore, the anti-jamming device has been widely used. However, the electronic information anti-jamming devices currently on the market only dissipate heat by opening a heat dissipation hole, and dust can easily enter the device through the heat dissipation hole, causing the device to age and need to be improved...
