Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning and protection, and relates to a cleaning and protection structure for an image recognition camera. Background Art

[0002] In coal mining enterprises, belt conveyors are an important means of coal transportation, with many advantages such as strong continuous transportation capacity, high operating efficiency, and easy automatic control. However, in the process of operation, almost all users have different degrees of longitudinal tearing problems, which has become one of the three major disasters of belt conveyors (longitudinal tearing, transverse tearing, and fire). In coal mines, once the belt conveyor longitudinal tearing occurs, the direct and indirect losses are very huge, which is a huge hidden danger to production safety.

[0003] The conveyor belt tear detection and identification camera uses a high-speed camera to collect images of the conveyor belt surface for intelligent identification and analysis. The equipment is installed between the upper and lower surfaces of the conveyor belt. A large amount of dust, coal slime and particles are generated along the belt. These mud stains are contaminated on the window glass or enter the shell and adhere to the lens. If they are not cleaned in time, it will affect the imaging and cause the equipment to misjudge.

[0004] At present, most tear identification instruments on the market have self-cleaning and dust removal functions, mainly using drum rotation dust removal and reciprocating wiper dust removal. Both dust removal methods can clean the window glass, but both methods require the drive motor inside the shell to drive the dust removal components on the window glass through the transmission components. Since high-precision devices such as cameras are installed in the shell, in order to avoid dust and water vapor entering the shell and affecting the instrument, this puts forward higher requirements on the sealing of the shell, because once dust, coal slime, water vapor, etc. enter the shell, they will adhere to the lens of the high-speed camera, interfere with the imaging, and cause misjudgment, wrong judgment, etc. Due to its transmission characteristics, the transmission components usually use sealing rings for dynamic sealing, but the existing sealing structure still has the situation that dust and water vapor enter the shell through the transmission components, which has an adverse effect on the imaging of the instrument.
