[0024] Embodiment:

[0025] Referring to Figures 1-4 , an on-line marine water quality monitoring sensor disclosed by the present invention includes a buoy main body 1. Two water quality monitoring sensors 12 are installed at the lower end of the buoy main body 1, and a guardrail 10 is arranged on the circumferential side of the two water quality monitoring sensors 12. The guardrail 10 is rotatably connected to the lower end of the buoy main body 1;

[0026] A rotating assembly is arranged between the guardrail 10 and the buoy main body 1. The rotating assembly includes an internal gear ring 14 and two electric half gears 13. The internal gear ring 14 is fixedly connected to the circumferential inner wall of the guardrail 10. The two electric half gears 13 are both rotatably connected to the lower end of the buoy main body 1, and the two electric half gears 13 are both intermittently engaged with the internal gear ring 14.

[0027] In this embodiment, the water quality monitoring sensor 12 can detect the water quality of seawater. One of the two electric half-gears 13 is in a meshed state with the internal gear ring 14, and the other is in a non-meshed state. When the electric half-gear 13 meshes with the internal gear ring 14, the electric half-gear 13 drives the internal gear ring 14 to rotate clockwise, thereby driving the guardrail 10 to rotate clockwise. When the other electric half-gear 13 meshes with the internal gear ring 14, the internal gear ring 14 rotates counterclockwise, and the internal gear ring 14 drives the guardrail 10 to rotate counterclockwise, which can drive the guardrail 10 to rotate forward and backward to scare away the approaching fish. Preferably, a PCL controller is provided on the buoy main body 1, which can control the start of the electric half-gear 13 and the water quality monitoring sensor 12. The model of the water quality monitoring sensor 12 can be selected by relevant personnel in the field.

[0028] Further, specifically refer to Figure 1 , two towing chains 2 are arranged on the circumferential side of the buoy main body 1, and counterweights 3 are fixedly connected to the lower ends of the two towing chains 2. Reeling assemblies are arranged on the two towing chains 2 for reeling the towing chains 2.

[0029] In this embodiment, the counterweight 3 can sink to the bottom of the water, which is convenient for limiting the position of the buoy main body 1 and preventing the buoy main body 1 from floating too far along with the water flow.

[0030] Further, specifically refer to Figure 1 , the reeling assembly includes a first electric reeling roller 9. The first electric reeling roller 9 is installed on the circumferential side of the buoy main body 1, and the towing chain 2 is fixedly connected to the circumferential side of the first electric reeling roller 9.

[0031] In this embodiment, when the first electric reeling roller 9 is started, the first electric reeling roller 9 rotates, and the towing chain 2 gradually wraps around the surface of the first electric reeling roller 9. When retrieving the buoy main body 1, the counterweight 3 can be salvaged.

An electric turntable 7 is installed at the upper end of the installation frame 4, and a signal generator 8 is arranged at the upper end of the electric turntable 7.

[0033] In this embodiment, when the electric turntable 7 and the signal generator 8 are started, the electric turntable 7 can drive the signal generator 8 to rotate, enabling the signal generator 8 to better transmit signals such as data information. A satellite locator can also be arranged on the installation frame 4 to facilitate grasping the position of the buoy main body 1.

[0034] Further, specifically refer to Figure 3, both sides of the mounting frame 4 are hinged with solar panels 5, and an adjusting mechanism is arranged between the mounting frame 4 and the solar panels 5 for adjusting the angles of the solar panels 5.

[0035] In this embodiment, the solar panels 5 can convert solar energy into light energy. A storage battery can be arranged on the floating body 1. The electric energy converted by the solar panels 5 is stored in the storage battery for starting various electrical devices. The solar panels 5 can be opened when the sunlight is good to shade the floating body 1, and can also improve the conversion efficiency of light energy and prevent the light on the solar panels 5 from being blocked. Preferably, the upper end of the solar panels 5 is hinged to the upper part of the side of the mounting frame 4.

[0036] Further, specifically refer to Figure 4 , the adjusting mechanism includes a mounting plate 15 with a mounting groove at the upper end. The mounting plate 15 is fixedly connected between the side walls of the mounting frame 4. Springs 17 are fixedly connected to one side of both solar panels 5, and the two springs 17 are respectively fixed to both sides of the mounting plate 15. Pulling ropes 18 are fixedly connected to one side of both solar panels 5, and a pulling member is arranged between the two pulling ropes 18 for pulling the solar panels 5.

[0037] In this embodiment, when the angles of the solar panels 5 need to be adjusted, the pulling ropes 18 pull the solar panels 5 closer to the mounting frame 4, and the springs 17 are in a compressed state, so that the angles of the solar panels 5 can be adjusted. The angles of the solar panels 5 can be adjusted according to environmental factors, etc., so as to improve the service life of the solar panels 5. An environmental monitor can also be arranged on the mounting frame 4, and the angles of the solar panels 5 can be controlled according to the weather to achieve the purpose of protection.

[0040] Further, specifically refer to Figure 4 , the pulling member includes a second electric winding roller 16. The second electric winding roller 16 is rotatably connected to the inner bottom wall of the mounting plate 15, and both pulling ropes 18 are fixed to the circumferential side of the second electric winding roller 16.

[0041] In this embodiment, the second electric winding roller 16 is started, and the second electric winding roller 16 rotates, and the towing rope 18 is gradually wrapped around the surface of the second electric winding roller 16.

The electric half gear 13 is started. When the moving electric half gear 13 meshes with the internal gear ring 14, the electric half gear 13 drives the internal gear ring 14 to rotate clockwise, thereby driving the guardrail 10 to rotate clockwise. When another electric half gear 13 meshes with the internal gear ring 14, the internal gear ring 14 rotates counterclockwise, and the internal gear ring 14 drives the guardrail 10 to rotate counterclockwise, which can drive the guardrail 10 to rotate forward and backward to scare away the approaching fish, prevent the fish from approaching and hitting the water quality monitoring sensor 12, causing damage to the water quality monitoring sensor 12, and prevent the fish from hitting and causing damage to the water quality monitoring sensor 12, affecting the accuracy of the monitoring data.
