Automatic dust and pollution prevention device of optical window

Abstract

The invention discloses an automatic dust and pollution prevention device of an optical device. A device (such as a camera shooting instrument, a laser distance measuring machine, an infrared detector, an optical sensor and other light receiving and emitting devices) provided with the optical window is placed in a sealed protection shell, a thin film optical window is arranged on the wall face, opposite to the optical window, of the sealed protection shell, and thin film paper arranged in the thin film optical window has the automatic updating function. Therefore, the automatic dust and pollution prevention device can effectively overcome the technical defects that in the prior art, the optical window of a lens, an optic and the like can not be automatically cleaned and maintained and air and water need to be supplied to devices of the optical window of the lens, the optic and the like, and solves the technical problem that the optical window of the lens and the optic and the like can not be cleaned and maintained when the device provided with the optical window is installed in field high air, special fields and dangerous environments. Besides, the automatic dust and pollution prevention device of the optical device has the advantages of being reasonable in design, high in universality, wide in application range, small in size, compact in structure, high in automation degree, convenient to use and maintain and the like.

Description

Technical field [0001] The invention relates to an automatic dust-proof and anti-fouling device for optical windows, which uses high light-transmitting film paper to cover optical windows such as lenses and lenses, so as to achieve protection against various dust, smoke, liquid splashes, gas impurities and other pollutants and lenses and lenses. Wait for the isolation of the optical window; at the same time, the high light transmission film paper can be automatically replaced. Background technique [0002] At present, light receiving and transmitting devices and equipment such as various cameras, laser ranging, infrared detection, and optical sensors are used more and more widely. However, in various mines, roadways, factories, vehicles, outdoor and other special fields, etc. In harsh environments, the surface of optical lenses, lenses and other optical windows are often contaminated due to dust, smoke, liquid splash, gas impurities and other pollutants, resulting in: 1. The imag...

Problems solved by technology

[0002] At present, various cameras, laser ranging, infrared detection, optical sensors and other light receiving and emitting devices and equipment are used more and more widely. However, in various mines, roadways, factories, vehicles, outdoors and other special fields, etc. In places with harsh environments, dust, smoke, liquid splash, gas impurities and other pollutants often cause the surface of optical lenses, lenses and other optical windows to be polluted, resulting in: 1. The image taken by the camera is blurred; 2. The laser distance measurement is not accurate. Accurate; 3. Infrared detection sensitivity is reduced; 4. Optical sensors and other light receiving and emitting devices and equipment cannot work normally due to the decrease in light transmittance caused by lens, lens and window pollution; It is used in the field, hazardous environment and other conditions that require cleaning and maintenance of lenses, lenses and optical windows
