Large-section long tunnel fan control device

The invention discloses a large-section long tunnel fan control device which comprises an equipment shell, two sets of heat dissipation mechanisms are arranged on the left side and the right side of the equipment shell, each heat dissipation mechanism comprises an electric motor, heat dissipation fan blades and a dustproof net, four sets of buffer devices are arranged on the upper surface of the equipment shell, and each buffer device comprises a supporting block, a reset spring and a connecting rod. A base is arranged on the lower surface of the equipment shell, fixing clamping grooves are formed in the lower positions of the left side and the right side of the equipment shell correspondingly, and fixing blocks are fixedly connected into the two fixing clamping grooves correspondingly. When the weather temperature is too high, an electric motor is started, the electric motor drives heat dissipation fan blades to rotate, heat in the device is dissipated, meanwhile, the heat dissipation fan blades drive a rota
