Problems solved by technology

When there is too much dust attached to the camera lens, it will greatly affect the shooting quality, and the monitoring personnel cannot obtain accurate underground information
At present, the work of cleaning the camera lens is mainly done manually. Manual cleaning is time-consuming and laborious, and it also needs to face certain dangers.

Embodiment 1

[0058] A camera protection system for coal mines with automatic lens replacement and cleaning and dust removal and dust reduction functions, including: a lens cleaning device, a lens drying device, an internal pressurization device, an external lens cover, a lens bracket, a housing, and a controller;

[0059] The housing includes an upper housing 1 and a lower housing 2. The lens cleaning device cleans the lens in the lower housing, and the lens drying device performs drying of the cleaned lens in the upper housing. At least two A lens is used to replace the working lens and replace it with a new lens when cleaning is required. The camera is located in the upper housing, and the lens of the lens bracket is placed in front of the camera lens; a through hole is provided on the side of the upper housing, and the camera passes through the through hole and the lens to complete the video monitoring work; an external lens cover is set outside the through hole, which is used to seal an...

Embodiment 2

[0072] A camera protection system for coal mines with the functions of automatic lens replacement and cleaning and dust removal. The various devices inside the body are inspected and maintained.

Embodiment 3

[0074] A camera protection system for coal mines with automatic lens replacement and cleaning and dust removal and dust reduction functions. Its structure is as described in Embodiment 1. The difference is that the system also includes a dust suppression device. replacement cycle. The dust suppression device is placed on the outside of the top of the upper shell, and is used to sprinkle water and dust on the outer periphery of the system;

[0075] The dust suppression device includes a second water tank 49, the second water pump 47 is fixedly installed on the water tank cover 48, and each of the two ends of the right-angle water pipe joint 46 is connected with a section of stainless steel water pipe 45, wherein one section of stainless steel water pipe 45 is connected with the second water pump 47, and the other section is connected with the first water pump 47. The electric on-off valve 44 is connected, and the first electric on-off valve 44 stretches out a section of right-a...

Abstract

The invention relates to a coal mine camera protection system with automatic lens replacing, cleaning, dust removing and dust falling functions and application thereof, and belongs to the technical field of mining equipment, which comprises a lens cleaning device, a lens drying device, an internal pressurizing device, an external lens cover, a lens bracket, a shell and a controller. When the lens is replaced, the underground use safety performance of the system is improved through the external lens cover and the internal pressurizing device, the camera window can be cleaned instead of manual work after the system is applied to the site, the labor intensity is reduced, the life safety of personnel is guaranteed, and the system is externally provided with a device capable of sprinkling water to reduce dust and is started when the external dust concentration is too high. The dust concentration around the camera system is rapidly reduced, and the lens cleaning frequency can be reduced. Unmanned cleaning of the camera window is achieved, meanwhile, cleaning and drying work is carried out in the shell, cleaning and drying equipment is isolated from flammable and explosive gas, and explosion-proof design of system equipment is better facilitated.

Description

technical field [0001] The invention relates to an automatic cleaning and protection system for a mine camera, in particular to a camera protection system for a coal mine with the functions of automatic lens replacement and cleaning and dust removal and dust reduction and its application, which belongs to the technical field of mining equipment. Background technique [0002] At present, the development direction of coal mining is to pursue "unmanned" underground, that is, to minimize the use of personnel during the mining operation and ensure the safety of personnel during the mining process. The environment in the mine is dark, and the probability of various accidents is high. The use of cameras in the mine can transmit the underground information to the central control room, and can detect and deal with potential safety hazards in time. A large amount of dust will be generated during coal mining and transportation. The cameras used in underground mines all need to face the...
