Description

Technical Field

[0001] This utility model relates to the field of fish activity monitoring technology, and in particular to a fish underwater activity monitoring device. Background Technology

[0002] When the aquatic environment changes or fish are stimulated in some way, they will exhibit abnormal behavior. For example, when a fish is sick, its swimming speed will slow down and its reaction time to external stimuli will be longer; when there is a lack of dissolved oxygen in the water, fish will swim to the surface; when fish are infected with parasites, they will exhibit jumping behavior. Since fish live in water, it is inconvenient to monitor them using traditional manual observation methods. Generally, underwater cameras can quickly, quantitatively, and intuitively monitor fish activity, but it is difficult to capture fish movements at night when there is insufficient light. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a fish underwater activity monitoring device. A motor on a rotating disk rotates a lead screw, causing a sliding frame threaded to the lead screw to raise and lower a fixed block. The raising and lowering of the fixed block allows the underwater camera connected to the fixed block to also be raised and lowered. A motor further rotates a gear, causing a gear ring meshing with the gear to rotate the rotating disk, thus allowing the underwater camera to rotate. This device is suitable for complex environments. A hydraulic rod on the fixed block extends and retracts, allowing the LED light hinged to the hydraulic rod to adjust its angle, providing the optimal illumination angle and improving the monitoring effect.

[0004] This utility model also provides a fish underwater activity monitoring device as described above, comprising: a hull, a fixing plate fixedly connected to the outer surface of the hull, a fixing frame fixedly connected to the upper surface of the fixing plate, a mounting frame fixedly connected to the inner side of the fixing frame, a motor one mounted on the inner side of the mounting frame, a gear fixedly connected to the output end of the motor one, a gear ring meshing with the outer surface of the gear, a rotating disk fixedly connected to the lower surface of the gear ring, a motor two fixedly connected to the upper surface of the rotating disk, a lead screw fixedly connected to the output end of the motor two, a sliding frame threadedly connected to the outer surface of the lead screw, a fixing block fixedly connected to the lower surface of the sliding frame, and a mounting bracket mounted on the lower surface of the fixing block. The underwater camera has a hydraulic rod hinged to the lower surface of the fixed block. An underwater LED light is hinged to the output end of the hydraulic rod. The outer surface of the underwater LED light is rotatably connected to the fixed block. A motor on a rotating disk rotates a lead screw, causing a sliding frame threaded to the lead screw to raise and lower the fixed block. This raising and lowering of the fixed block allows the underwater camera connected to it to move up and down. A motor then rotates a gear, causing a gear ring meshing with the gear to rotate the rotating disk, allowing the underwater camera to rotate. This design is suitable for complex environments. The extension and retraction of the hydraulic rod on the fixed block allows the angle of the LED light hinged to the hydraulic rod to be adjusted, providing the optimal illumination angle and improving monitoring effectiveness.

[0005] According to the present invention, a fish underwater activity monitoring device has a protective shell fixedly connected to the upper surface of the fixing plate. The positions of the first motor, the second motor, the gear, and the gear ring are all located inside the protective shell. The protective shell protects the key components such as the first motor, the second motor, the gear, and the gear ring inside, effectively preventing damage to these precision components from the external environment and extending the service life of the equipment.

[0006] According to the present invention, an underwater fish activity monitoring device is provided with a ventilation port on the outer surface of the protective shell, and one end of the lead screw is rotatably connected to the fixing frame. The ventilation port on the outer surface of the protective shell helps to dissipate heat and prevent the motor from overheating due to long-term operation.

[0008] According to the present invention, an underwater fish activity monitoring device is provided, wherein the outer surface of the sliding frame is slidably connected to the rotating disk, the underwater LED light is located outside the underwater camera, and the sliding connection design between the sliding frame and the rotating disk ensures that the underwater camera remains stable during the lifting and lowering process.

[0009] According to the present invention, in a fish underwater activity monitoring device, the outer surface of the fixing frame abuts against the inner wall of the protective shell, the underwater camera is located on the outside of the hull, and the abutment design between the fixing frame and the inner wall of the protective shell enhances the rigidity of the overall structure.

[0010] According to the present invention, an underwater fish activity monitoring device is provided, wherein an LED light is installed on the upper surface of the protective shell, and an opening and closing cover is hinged to the outer surface of the LED light. The LED light is installed on the upper surface of the protective shell to provide lighting for the personnel on board, and the opening and closing cover design on its outer surface facilitates the protection of the light body.

[0011] According to the present invention, an underwater fish activity monitoring device is provided, wherein the LED lighting is located above the hull to provide sufficient lighting for the crew, especially at night or in low-light conditions, to ensure the safety of the crew on deck.

[0024] Specifically, the fixing plate 2 is fixed to the outside of the hull 1. The center of the fixing plate 2 has a rotating disk 8. The motor 9 on the rotating disk 8 rotates the lead screw 16, which causes the sliding frame 10, which is threaded to the lead screw 16, to rise and fall. The rising and falling of the sliding frame 10 causes the fixing block 11 to rise and fall. The rising and falling of the fixing block 11 causes the underwater camera 12 connected to the fixing block 11 to rise and fall. Then, the motor 5 on the mounting bracket 4 rotates the gear 6, which causes the gear ring 7 meshing with the gear 6 to rotate. The rotation of the gear ring 7 causes the rotating disk 8, which is fixed to the gear ring 7, to rotate, so that the underwater camera 12 on the fixing block 11 can rotate. This is suitable for complex environments. At the same time, the fixing plate 2 has a protective shell 15 to protect key components such as the motor 5, the motor 9, the gear 6, and the gear ring 7. The fixing plate 2 also has an LED light 17 to provide lighting for the personnel on the hull 1.

[0025] Reference Figure 1 and Figure 3 An underwater camera 12 is mounted on the lower surface of the fixing block 11. The underwater camera 12 is located on the outside of the hull 1.

The underwater LED light 14 is located on the outside of the underwater camera 12. The outer surface of the underwater LED light 14 is rotatably connected to the fixing block 11.

[0026] Specifically, the underwater LED light 14 and the illumination LED light 17 are LED lights of specific wavelengths, such as blue light or red light.

[0027] Working principle: During use, the motor 9 on the rotating disk 8 rotates the lead screw 16, which allows the sliding frame 10, threadedly connected to the lead screw 16, to rise and fall. The rising and falling of the sliding frame 10 causes the fixed block 11 to rise and fall, which in turn causes the underwater camera 12 connected to the fixed block 11 to rise and fall. Then, the motor 5 on the mounting bracket 4 rotates the gear 6, which causes the gear ring 7 meshing with the gear 6 to rotate. The rotation of the gear ring 7 causes the rotating disk 8, which is fixed to the gear ring 7, to rotate, allowing the underwater camera 12 on the fixed block 11 to rotate. This is suitable for complex environments. When the light is not clear, the hydraulic rod 13 on the fixed block 11 can be extended and retracted, allowing the underwater LED light 14, which is hinged to the hydraulic rod 13, to adjust its angle and provide the best lighting angle, thus improving the monitoring effect of the underwater camera 12.
