Two groups of cleaning components are symmetrically arranged inside the box 6, and the cleaning components include cleaning roller brushes 51 distributed in a linear array, and the cleaning roller brushes 51 are transmission-connected to the cleaning strip 5. Warning lights 7 are symmetrically arranged on the cleaning box 6. A first trigger switch 71 and a second trigger switch 72 are also arranged inside the cleaning box 6. The first trigger switch 71 and the second trigger switch 72 are both electrically connected to the warning light 7, so that the cleaning strip 5 is driven to rotate by the rotating motor 2 in cooperation with the multi-stage electric push rod 3, so that the cleaning roller brush 51 cleans away the dust attached to the monitoring end of the monitor 4. At the same time, when the monitor 4 is detecting, the warning light 7 is activated by the first trigger switch 71 to light up red to serve as a warning, and when the monitor 4 is not detecting, the warning light 7 is activated by the second trigger switch 72 to light up green to serve as a reminder.

[0027] It should be added that the monitoring end of the existing monitor 4 is a fan blade structure, and both the input end and the output end are provided with filter nets. The cleaning roller brush 51 in this device cleans the dust attached to the monitoring end of the monitor 4, which is to clean the dust on the filter net; the existing warning light 7 controls the two lighting states through two switches, which is also common knowledge and will not be elaborated here.

[0028] like Figures 2 to 4 As shown, a mounting frame 31 is provided at the output end of the multi-stage electric push rod 3, and the monitor 4 and the cleaning strip 5 are both arranged on the mounting frame 31, so that the monitor 4 and the cleaning strip 5 on the mounting frame 31 are driven to move by the multi-stage electric push rod 3, and then the cleaning roller brush 51 is driven to rotate by the cleaning strip 5 to clean off the dust attached to the monitoring end of the monitor 4.

[0029] like Figure 2 and Figure 3As shown, an inlet 61 is provided on one side of the cleaning box 6, and an outlet 62 is provided on the bottom of the cleaning box 6. The vertical plane of the outlet 62 coincides with the vertical plane of the inlet 61, and the two groups of cleaning components are symmetrically distributed with the vertical plane of the inlet 61 as the center plane, so that the monitor 4 enters the interior of the cleaning box 6 from the inlet 61, and at the same time, the dust cleaned from the monitoring end of the monitor 4 is discharged from the cleaning box 6 from the outlet 62.

[0030] like Figures 2 to 4 As shown, the cleaning roller brush 51 is rotatably arranged inside the cleaning box 6, and a connecting gear 52 is provided on the top surface of the cleaning roller brush 51. Several connecting gears 52 are meshingly connected. A cleaning wheel 53 is provided on a connecting gear 52 close to the inlet 61 in each group of cleaning components, so that the two cleaning wheels 53 are driven to rotate through the cleaning bar 5, so that the connecting gear 52 connected to the two cleaning wheels 53 drives the remaining connecting gears 52 to rotate synchronously, thereby driving all the cleaning roller brushes 51 to clean the dust attached to the monitoring end of the monitor 4.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, a trigger cylinder 73 is provided inside the cleaning box 6, and a trigger block 74 is slidably provided inside the trigger cylinder 73. A trigger spring 75 is provided between the trigger block 74 and the inner wall of the trigger cylinder 73, and a trigger rod 76 is provided on the trigger block 74. The other end of the trigger rod 76 extends to the outside of the trigger cylinder 73 near the inlet 61. The first trigger switch 71 is provided on the side of the trigger cylinder 73 near the inlet 61, and the second trigger switch 72 is provided on the side of the trigger cylinder 73 away from the inlet 61. The distance between the first trigger switch 71 and the second trigger switch 72 is equal to the travel distance of the trigger rod 76. Therefore, through the cooperation of the trigger cylinder 73, the trigger block 74, the trigger spring 75 and the trigger rod 76, when the monitor 4 performs detection, the warning light 7 is activated by the first trigger switch 71 to light up the red light to serve as a warning, and when the monitor 4 does not perform detection, the warning light 7 is activated by the second trigger switch 72 to light up the green light to serve as a reminder.

[0032] Working principle: First, the monitoring platform 1 is installed on the top of the mine tunnel through the bolts and the mounting holes 11. When it is necessary to monitor the ventilation inside the mine tunnel, the rotating motor 2 is cooperated with the multi-stage electric push rod 3 to drive the monitor 4 to move up, down, left and right inside the mine tunnel, so as to fully monitor the ventilation inside the mine tunnel. When it is necessary to clean the dust attached to the monitoring end of the monitor 4, the rotating motor 2 is cooperated with the multi-stage electric push rod 3 to drive the monitor 4 to move to the direction of the inlet 61 of the cleaning box 6, and then the multi-stage electric push rod 3 drives the monitor 4 to enter the interior of the cleaning box 6 from the inlet 61. At this time, the multi-stage electric push rod 3 will drive the cleaning bar 5 to contact the two cleaning wheels 53. At the same time, as the cleaning bar 5 moves, the two cleaning wheels 53 rotate. When the cleaning wheel 53 rotates, it will drive the connecting gear 52 connected to it to rotate, and at the same time drive the remaining connecting gears 52 to rotate synchronously. When the connecting gear 52 rotates, The cleaning roller brush 51 is driven to rotate, thereby cleaning the dust attached to the monitoring end of the monitor 4. The cleaned dust will be discharged from the cleaning box 6 from the outlet 62. When the cleaning bar 5 moves to abut against the trigger rod 76, the trigger rod 76 will be pushed toward the inside of the trigger tube 73. At this time, the trigger rod 76 will drive the trigger block 74 to disengage from the first trigger switch 71 and then move to the second trigger switch 72, so that the warning light 7 lights up green to serve as a reminder. During this process, the trigger block 74 will squeeze the trigger spring 75 to deform it. Then, when the monitor 4 is required to monitor the ventilation inside the mine tunnel, the multi-stage electric push rod 3 is used to drive the monitor 4 to move out of the cleaning box 6 from the inlet 61. At this time, the trigger block 74 will be driven to disengage from the second trigger switch 72 and then move to the first trigger switch 71 under the elastic force of the trigger spring 75 to restore the deformation, so that the first trigger switch 71 starts the warning light 7 to light up red to serve as a warning.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
