Camera lens protection device

Abstract

The invention discloses a camera lens protection device, and relates to the technical field of cameras. The device comprises a first connecting cylinder and a second connecting cylinder; the first connecting cylinder is arranged on a camera lens in a sleeving mode; the second connecting cylinder is fixedly mounted at one end of the first connecting cylinder; the diameter of the second connecting cylinder is gradually increased in a direction away from the first connecting cylinder in a trumpet shape; a first cavity is formed in the first connecting cylinder in the circumferential direction; an opening communicating with the first cavity is formed in the outer wall of the first connecting cylinder; the opening is provided with a micro exhaust fan; the opening is further provided with a filter cover; the filter cover covers the micro exhaust fan; the second connecting cylinder is provided with a second cavity in the circumferential direction; the second cavity communicates with the first cavity; and a plurality of exhaust holes communicating with the second cavity are formed in the inner side wall of the second connecting cylinder in the annular direction. According to the device, an airflow protection area is formed in front of the camera lens, so that dust in an environment is prevented from falling onto the camera lens, and the camera shooting quality of the camera is improved.

Description

technical field [0001] The invention belongs to the technical field of cameras, in particular to a camera lens protection device. Background technique [0002] On the factory production line, industrial cameras are usually installed above the conveyor belt to collect images of items on the conveyor belt. The collected images are analyzed and processed. The environment in the factory directly affects the working status of the camera, which affects the quality of the image. However, the vast majority of factories have a lot of dust, which can easily blur the lens of the camera, resulting in the deterioration of the quality of the collected images and affecting the later analysis and processing. Therefore design the protection of a kind of camera lens to appear very necessary.
