The rotation setting of the brush holder drives the brush plate to realize the physical cleaning of the dirt on the outer surface of the glass tube cover.

[0023] 3. In the present invention, when the glass tube cover performs self-maintenance on the surface, the spray pipe first discharges liquid at high pressure. After the spray pipe discharges liquid at high pressure, the dirt on the outer surface of the glass tube cover is cleaned and flushed. By supplying the cleaning liquid and setting the scraper, the cleaning effect of the surface of the glass tube cover is effectively improved, and then the high transparency effect of the monitoring device during the monitoring operation is achieved. By realizing the above-mentioned self-maintenance function, the maintenance and use costs of the device can be effectively reduced. 4. The present invention provides two-way shock-absorbing protection for the camera and the monitor by setting a shock-absorbing spring on the T-shaped suspension rod, thereby improving the shock resistance of the monitoring device and the anti-shake effect of the monitoring image of the monitoring device. By setting the hanging ball, the suspension rod and the limit spring, the monitoring device can self-absorb the impact force when subjected to an external impact and achieve self-reset of the device after the impact force is removed, thereby making the monitoring device have shock-proof and anti-collision functions.

[0024] 5. In the present invention, when the monitoring device is in normal working mode, the two axial flow fans both supply air to the interior of the air guide ring cavity. After the axial flow fans supply air to the interior of the two air guide ring cavities, the air flow is ejected through the air outlet holes. After the air is discharged from the air outlet holes, on the one hand, the dirt or dust on the outer surface of the glass tube cover can be blown away, and on the other hand, the flow of dust to the surface of the glass tube cover can be effectively suppressed, thereby effectively reducing the dust accumulation rate on the surface of the glass tube cover.
