Photorefractive water entry detection device

Abstract

The invention discloses a light refraction type water detection device. The water detection device comprises a shell, wherein a light source is arranged on one side in the shell, and a first transparent waterproof plate is mounted on one side located in front of the light source in the shell; two photosensitive devices are arranged on the other side in the shell at intervals, the photosensitive device farer from the light source is a first photosensitive device, the photosensitive device nearer to light source is a second photosensitive device, and a second transparent waterproof plate is arranged on the other side in front of the first photosensitive device and the second photosensitive device in the shell; and the included angle between a light-sensitive surface of the first photosensitive device and the second transparent waterproof plate is same as the included angle between an incident ray of the light source and a normal line of the first transparent waterproof plate. The light refraction type water detection device can rapidly respond and be conveniently realized, is relatively low in cost, high in reliability and detection property, is not influenced by the salinity difference of a water body, the atmospheric moisture and height and the like and has a state detection function, so that the online detection of system equipment can be realized.

Description

technical field [0001] The invention relates to the field of water entry detection devices, in particular to a photorefractive water entry detection device. Background technique [0002] At present, there are many types of water entry detection devices. According to the difference in physical properties between water and air, there are mainly several types that use electrical conductivity, thermal conductivity, buoyancy, and pressure. Each type of water entry detection device has its own characteristics. However, at present, the above-mentioned types of water entry detection devices basically do not have a self-contained state detection function, which brings difficulties to the realization of the task system's online detection of the state of the submersion sensor, which makes the automatic intelligence of the overall equipment not high enough. Therefore, the present invention proposes a water-entry detection device designed based on the principle of refraction of light fro...
