Abstract

The invention discloses an electronic information anti-interference device which comprises an anti-interference device body and cooling fans, wherein a plurality of heat dissipation openings are formed in the anti-interference device body; the cooling fans are installed at the positions, located at the heat dissipation openings, in the anti-interference device body; dust blocking mechanisms are installed at the positions, located at the heat dissipation openings, of the anti-interference device body; in each dust blocking mechanism, one side of a baffle is rotationally connected with one side wall of a ventilation opening, and the other sides of the baffle are each provided with a piece of blocking cloth, the orientation of a ventilation groove can be changed according to specific conditions, airflow can flow smoothly, external objects are prevented from shielding and blocking the heat dissipation opening, and the heat dissipation effect is improved; in addition, a plurality of driven fans are further installed in a dust blocking shell, the driven fans are matched with an inner plate and a bearing groove in the inner plate for use, the inner plate is used for blocking part of dust, and when the driven fans stop rotating, fan blades of the driven fans can be used for partially shielding the bearing groove, so that external dust is prevented from entering the anti-interference device body via the bearing groove. Therefore, the dust blocking effect of the electronic information anti-interference device is improved.

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; [0003] The existing electronic information anti-jamming device uses cooling holes on the casing of the anti-jamming device to dissipate heat. The heat dissipation effect is poor, and the external dust easily enters the anti-jamming device through the cooli...
