Description

An installation device for underwater illuminance sensor of fish-collecting lamp

technical field

The invention relates to a technical device for underwater optical radiation receiving and illuminance measurement, in particular to an installation device for an underwater illuminance sensor of a fish-collecting lamp.

Background technique

In the research of marine optics or the investigation of marine resources, the measurement of illuminance in seawater refers to the measurement of illuminance components in the horizontal plane. Therefore, it is required that the surface of the illuminometer sensor receiving light is in the horizontal plane. In order to improve the accuracy of the measurement, it is often necessary to consider the influence of the illuminance probe fixing device on the measurement. For example, if the surface of the supporting device is required to be all black, the influence of the reflected light on the surface should be reduced as much as possible, and the thinnest possible cable or traction rope should be used to reduce the impact on the surface. The occlusion effect of the sensor. However, the diameter of the cable and the traction rope is always limited and small, which will inevitably block the light sensor, resulting in a certain measurement error. The greater the impact, the greater the resulting error.

Especially since the light meter and the fixture may rotate around the traction rope in the water, the light to be measured, whether from the sun or an artificial light source, is obliquely incident on the sea surface and propagates into the water. It will inevitably cause the light entering the probe sensor to be blocked by cables or ropes during the rotation process, resulting in serious random errors. Therefore, in order to accurately measure the underwater illuminance, it is necessary to eliminate the rotation of the illuminance sensor mounting bracket around the pull rope.
