Embodiment 1

[0024] A zoom lighting device for underwater target detection, comprising a lens barrel 1, a lampshade 2, a zoom structure 3 and a light source 4; the light source 4 is arranged in the lens barrel 1, and the lampshade 2 is arranged at one end of the lens barrel 1 and The barrel 1 is connected; the zoom structure 3 is arranged at the front end of the light source 4 . The zoom structure 3 includes a focusing mirror 31; several astigmatic mirrors 311 and condenser mirrors 312 are distributed circumferentially on the focusing mirror 31; the astigmatic mirrors 311 and the condenser mirrors 312 are arranged indirectly; Corresponding to the light source 4; the astigmatism mirror 311 is used to disperse the light source 4; the condenser lens 312 is used to gather the light source 4 to the center of the focusing mirror 31; the center of the focusing mirror 31 is provided with a lens 313; the focusing The rotation of the mirror can be controlled by an adjustment mechanism 32 . The ligh...

Embodiment 2

[0035] Except for the adjustment mechanism, other structures are the same as in Embodiment 1, and the adjustment mechanism adopted in this embodiment is as follows:

[0036] The adjustment mechanism 32 includes two electromagnetic blocks 324 and a magnetic block 325; the electromagnetic blocks 324 are arranged on both sides of the limit bar; the magnetic block 325 is arranged on the limit block.

[0037] By energizing one end of the electromagnetic block, the electromagnetic block attracts the magnetic block and drives the focusing mirror to rotate. When it is necessary to switch the irradiation mode, one end of the electromagnetic block is powered off, and the other end of the electromagnetic block is powered on, so the magnetic block will approach the other end, thus Enables switching between spotlight and astigmatism.

Embodiment 3

[0039] The lighting equipment is set on the UAV, and the underwater organisms in the polluted area are dispersed by switching between light-concentrating and astigmatism; it is characterized in that the pollution level is confirmed before the area is dispersed, and the pollution source is used as the center of the circle, and the change of the pollution amount is less than 10 % of the circle is set as the heavily polluted circle; the circle with the change of pollution amount between 10% and 50% is set as the circle of medium pollution; the circle with the change of pollution amount greater than 50% is set as the circle of light pollution, which will be presented through the visualization system and presented to the public. The control center gives an early warning.

[0040] The sources of contamination are identified by:

[0041] S101: The underwater UAV is launched in polluted waters and dives, and the water quality data is detected once every time it dives to a certain dept...

Abstract

The invention provides a zoom lighting device for underwater target detection, which includes a lens barrel, a lampshade, a zoom structure and a light source; the light source is arranged in the lens barrel, and the lampshade is arranged at one end of the lens barrel and connected with the lampshade; the zoom structure It is set at the front of the light source; the irradiation range can be adjusted, so that the lighting equipment can meet the requirements of various lighting scenes.

Description

[0001] field of invention [0002] The invention belongs to underwater detection equipment, in particular to a zoom lighting equipment. Background technique [0003] When underwater drones conduct underwater exploration, they must be equipped with corresponding light sources to complete underwater shooting and photography. However, due to the complex underwater environment and the influence of impurities in the water, ocean depth and other factors, the lighting effect is greatly limited. When underwater drones observe different underwater targets, they have different requirements for illumination. In some specific environments, it is necessary to use focused strong light, and sometimes it is necessary to enhance the ambient light, expand the observation area, and let the light scatter in the observation environment. The existing underwater searchlights cannot switch the illumination range very well. Contents of the invention [0004] The invention provides a zoom lighting...
