[0097] When the thermal imaging camera 1 needs to be dusted, the controller 3 controls the motor 93 to start, the motor 93 works and drives the fan blades 94 to rotate, the fan blades 94 rotate and drive the dust brush 95 to rotate, so that the dust brush 95 cleans the thermal imaging camera 1, and dust removal of the thermal imaging camera 1 is achieved. At the same time, the filter 92 filters the air flowing into the mounting seat 51 to prevent dust in the air from entering the mounting seat 51 and contaminating the components in the mounting seat 51.

[0098] Reference Figure 3 and Figure 6The driving assembly 8 includes two first telescopic rods 81, two second telescopic rods 82 and a third telescopic rod 83. The fixed ends of the two first telescopic rods 81 are symmetrically and fixedly mounted on the mounting seat 51, the movable end of the first telescopic rod 81 is fixedly connected to the placement seat 61, and the rod cavity of the fixed end of the first telescopic rod 81 is filled with hydraulic fluid.

The fixed end of the third telescopic rod 83 is fixedly mounted on the mounting seat 51, the rodless cavity of the fixed end of the third telescopic rod 83 is connected to the rodless cavity of the fixed end of the first telescopic rod 81, and the rodless cavity of the movable end of the third telescopic rod 83 is filled with hydraulic fluid.

[0099] When the thermal imaging camera 1 needs to stop working, the movable end of the third telescopic rod 83 is pushed, the movable end of the third telescopic rod 83 is shortened, and the hydraulic fluid in the fixed end of the third telescopic rod 83 enters the rodless cavity of the fixed end of the first telescopic rod 81, and the movable end of the first telescopic rod 81 is extended. The movable end of the first telescopic rod 81 is extended, thereby driving the placement seat 61 to move away from the fixed slide rail 53, thereby driving the first slider 54 to move, and realizing the driving work of the installation component 5, and the length of the movable end of the first telescopic rod 81 is shortened, and the movable end of the first telescopic rod 81 is shortened, thereby drawing the hydraulic fluid in the rodless cavity of the fixed end of the second telescopic rod 82 into the rod cavity of the fixed end of the first telescopic rod 81, and the movable end of the second telescopic rod 82 is shortened, and the two top covers 52 move in a direction close to each other, realizing the closing work of the installation seat 51, and at the same time driving the two sliding sleeves 91 to move in a direction close to each other, so that the dust removal brush 95 abuts against the thermal imaging camera 1, which facilitates the work of the dust removal component 9.

[0100] On the contrary, when the thermal imaging camera 1 needs to start working, the movable end of the third telescopic rod 83 is pushed, the movable end of the third telescopic rod 83 is shortened, and the hydraulic fluid in the fixed end of the third telescopic rod 83 enters the rodless cavity of the fixed end of the first telescopic rod 81, and the movable end of the first telescopic rod 81 is extended. The movable end of the first telescopic rod 81 is extended, thereby driving the placement seat 61 to move away from the fixed slide rail 53, and then driving the first slider 54 to move, so as to achieve the driving work of the installation assembly 5, and finally the movable end of the first telescopic rod 81 is extended. The movable end of the first telescopic rod 81 is extended, and then the hydraulic fluid in the rod cavity of the fixed end of the first telescopic rod 81 is pushed into the rodless cavity of the fixed end of the second telescopic rod 82, and the movable end of the second telescopic rod 82 is extended, and the two top covers 52 move in the direction away from each other, so as to achieve the opening work of the installation seat 51.

[0101] The implementation principle of an electronic fence device for coal mines in the embodiment of the present application is as follows: the thermal imaging camera 1 is fixed on the installation component 5 by the placement component 6, and then the thermal imaging camera 1 is fixed on the work station by the fixing component 7. The controller 3 controls the operation of the thermal imaging camera 1 and drives the installation component 5 to work through the driving component 8, so that the thermal imaging camera 1 is exposed on the work station, which is convenient for monitoring the staff. At the same time, the thermal imaging camera 1 transmits the video monitoring data to the controller 3, and the controller 3 processes the monitoring data and outputs it to the display 4 and the voice sound and light alarm 2. The video data detected by the thermal imaging camera 1 can be directly observed through the display 4. When the staff violates the work regulations, the controller 3 controls the voice sound and light alarm 2 to alarm.
