The invention discloses a maintenance device for rail transit transportation, which comprises a shell, a mounting cavity is arranged in the shell, an electronic element is mounted in the mounting cavity, a mounting block is arranged at the upper end of the shell, the upper end of the mounting block is rotatably connected with a second rotating rod, and a plurality of arc-shaped fan blades are arranged on the outer wall of the second rotating rod along the circumferential direction of the second rotating rod. A moving cavity is formed in the mounting block, the lower end of the second rotating rod extends into the moving cavity and is fixedly connected with a cam, a piston is arranged in the moving cavity, and the piston is in sliding connection with the inner wall of the moving cavity. According to the device, gas in the mounting cavity can be actively replaced every time a train passes by, the heat dissipation effect of electronic elements in the indicator light is improved, the indicator light can be brushed after passing by a certain number of trains, the knowledge effect of the indicator light is ensured under the condition that normal use of the indicator light is not affected, and the service life of the indicator light is prolonged. Meanwhile, dust on the filter screen can be cleaned, so that the air permeability of the air inlet is ensured.
