[0033] The working principle of the utility model will be further described below.

[0034] In the use process of the depth-adjustable light attenuation coefficient monitoring device in the embodiment, first, according to the water depth of the water area to be tested, the corresponding specifications of the first light sensor 220, the depth sensor 230, the connecting cable 310 and the signal transmission line 240 are selected, so that the driving device 320 can drive the lifting platform 210 to freely rise and fall in the water area to be tested through the connecting cable 310, and the first light sensor 220 and the depth sensor 230 can collect data in real time. In actual application, the main body 100, the detection part 200 and the driving part 300 are put into the water area to be tested, and the buoy 130 floats on the water surface under the action of the buoyancy; the driving device 320 drives the lifting platform 210 to move close to or away from the buoy 130 through the connecting cable 310. The first light sensor 220 can monitor the light intensity at the current position in real time, and the depth sensor 230 can monitor the depth at which the first light sensor 220 is located in real time, and transmit the light intensity and the corresponding depth to the terminal through the controller 120 and the wireless module 160, so that the user can accurately obtain the light intensity and the corresponding depth at which the first light sensor 220 is located, realize real-time data collection and calculation, and remotely transmit to the relevant user.

[0035] When it is necessary to adjust the depth at which the first light sensor 220 is located, the user sends a moving instruction to the wireless module 160 through the terminal. After receiving the up or down instruction, the controller 120 sends a start instruction to the driving device 320, and drives the disc line shaft 150 to wind or loosen the connecting cable 310, so that the connecting cable 310 drives the lifting platform 210 to move up and down in the vertical direction. When the reading of the depth sensor 230 reaches the preset depth, the driving device 320 stops working. Since the first light sensor 220 and the depth sensor 230 are placed on the lifting platform 210 and are in the same horizontal plane, they can be automatically moved in the vertical direction underwater through the connecting cable 310 and the driving device 320. Therefore, the buoy 130 can adapt to any water depth, and after being put into the water, it can automatically collect the gradual change of the underwater light intensity in the vertical direction in the water body, avoiding the need to manually adjust the depth position of the first light sensor 220 on site, improving the use convenience and data accuracy of the depth-adjustable light attenuation coefficient monitoring device; at the same time, the first light sensor 220 can collect the underwater visible light irradiance at any depth underwater, and perform fine surface analysis on the light attenuation of the water layer.

[0036] In practical application, the light intensity of water surface is monitored in real time by adding a second light sensor 260 on the top of the buoy 130 to calibrate the error caused by the instantaneous change of the incident light of water surface during measurement. This is because the measurement data of the first light sensor 220 will change with the change of water depth and the change of the incident light of water surface, and the light attenuation coefficient to be measured is to describe the change rate of the attenuation of the incident light in the vertical direction, and the error caused by the change of the incident light during measurement (such as the change of the incident light caused by the movement of the cloud layer) needs to be excluded. Therefore, the depth-adjustable light attenuation coefficient monitoring device needs to record the ratio (unit: %) of the underwater downlink light radiation intensity at different water depths to the incident light radiation intensity of the water surface, and then calculate the light attenuation coefficient according to the Beer-Lambert underwater light attenuation model.

[0037] From the above description, the depth-adjustable light attenuation coefficient monitoring device is provided with the detection part 200 and the driving part 300, the driving device 320 can drive the first light sensor 220 and the depth sensor 230 on the lifting platform 210 to reciprocate in the vertical direction, at the same time, the second light sensor 260 can collect the water surface incident light brightness in real time, the depth sensor 230 can accurately position the lifting platform 210 to the preset depth, and the first light sensor 220 can collect the data of different water depths and convert into the percentage of the water surface incident light, so as to eliminate the error caused by the random change of the water surface incident light in the monitoring process, and improve the data acquisition flexibility and adjustment convenience of the depth-adjustable light attenuation coefficient monitoring device; the main body 100 and the detection part 200 are arranged, the battery 110 can continuously supply power to the detection part 200 and the driving part 300, so that the controller 120 can collect data in real time and accurately through the first light sensor 220 and send it outward, and the data acquisition accuracy and timeliness of the depth-adjustable light attenuation coefficient monitoring device are improved; the guide wheel 140 is arranged, the connection flexibility of the float 130 and the connecting cable 310 is ensured, the driving device 320 can accurately position the lifting platform 210 in the vertical direction, and the data acquisition accuracy of the depth-adjustable light attenuation coefficient monitoring device is improved; the cross rod 131 is arranged, the structural stability of the float 130 is ensured, the deformation of the float 130 during the working process is avoided, the connection stability of the lifting platform 210 and the float 130 is ensured, and the service life of the depth-adjustable light attenuation coefficient monitoring device is improved; the signal transmission line 240 is arranged, the communication stability between the first light sensor 220 and the depth sensor 230 and the controller 120 is ensured, the controller 120 cannot acquire the reading of the first light sensor 220 and the depth sensor 230, the data acquisition accuracy of the depth-adjustable light attenuation coefficient monitoring device is ensured; the counterweight 250 is arranged, the connecting cable 310 can stably pull the lifting platform 210 to move in the vertical direction, the inclination of the lifting platform 210 during the movement is avoided, the lifting platform 210 moves in the vertical direction underwater, and the data acquisition accuracy of the depth-adjustable light attenuation coefficient monitoring device is improved.
