Problems solved by technology

Because the underground environment is relatively humid and there are many small particles floating in the air, after the video surveillance system has been working for a period of time, a layer of dust will adhere to the surface of the lens, resulting in a decrease in the picture definition of the video surveillance system, and due to the cable video surveillance system line Intricate and complex, causing certain safety hazards to coal mine workers
When the camera in the video surveillance system is wiped manually, it is easy to cause damage to the lens. At the same time, the video surveillance system is generally placed at a high place, and it may cause unnecessary trouble to normal work without manual wiping and wiring.

Embodiment 1

[0072] A coal mine underground video surveillance system capable of automatic charging and mirror cleaning, including a protection device 1, a lighting device 2, a cleaning device 3, a lifting device 4, a control device 5, an air blowing device 6, a grabbing device 7, and an energy device 8.

[0073] A camera 15 is arranged in the protection device, and the protection device is used to protect the camera against corrosion and explosion.

[0074] The lighting device includes an infrared lamp, and the lighting device is placed above the protective device for providing lighting.

[0075] The cleaning device includes an external cleaning structure and an internal cleaning structure. The external cleaning structure is placed on the side of the protection device to clean the camera lens to avoid excessive dust influence, and the internal cleaning structure is used to provide cleaning liquid.

[0076] The lifting device includes a motor and a connecting rod. One end of the connecting...

Embodiment 2

[0091] A coal mine underground video monitoring system capable of automatic charging and mirror surface cleaning, its structure is as described in Embodiment 1, the difference is that two through holes are provided on the side of the protective shell, and a supplementary pull is provided through the slideway at the through holes. Doors, that is, the clean water tank sliding door 12 and the cleaning agent sliding door 13, the sliding doors can move up and down through the slideway, and are used to replenish clean water and cleaning agent from the outside to the cleaning device; The environment can be explosion-proof and moisture-proof.

Embodiment 3

[0093] A coal mine underground video surveillance system capable of automatic charging and mirror surface cleaning, its structure is as described in Embodiment 1, the difference is that the number of decks is four, protected around the camera from top to bottom, left and right, each deck is connected to the protection There are 4 buffer devices connected between the housings. The buffer devices can be flexible objects such as springs and rubber pads, in order to make the video surveillance system work stably and reliably in emergencies.

Abstract

The invention discloses a coal mine underground video monitoring system capable of automatic charging and mirror surface cleaning and its application, including a protection device, a lighting device, a cleaning device, a lifting device, a control device, a blowing device, a grabbing device, and an energy device. The control device realizes the intelligent operation of the video surveillance system. The protection device can make the whole anti-corrosion and explosion-proof. The brush is used to clean the lens to avoid excessive dust influence. The lifting device realizes the up and down movement and 360° rotation of dynamic video monitoring under the action of the control device. The blower in the blower device dedusts the lens through the explosion-proof hose under the action of the control device. Drying, the grabbing device realizes the replacement of rechargeable batteries through the flying manipulator, and the charging base station in the energy device is used to store spare rechargeable batteries to ensure the long-term stable operation of the video surveillance system.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a coal mine underground video monitoring system capable of automatic charging and mirror surface cleaning and its application, which belongs to the technical field of mining equipment. Background technique [0002] With the wide application of intelligent technology in the coal mine industry, for safe production work and daily underground management, the camera is used as the main body of the video surveillance system and installed on mines and underground mechanical equipment to realize real-time monitoring and effective monitoring of safe production. Improve management efficiency. Because the underground environment is relatively humid and there are many small particles floating in the air, after the video surveillance system has been working for a period of time, a layer of dust will adhere to the lens surface, resulting in a decrease in the picture definition of the video surveill...
