Abstract
Description
Technical Field
[0001] This utility model relates to the field of fishing gear technology, specifically to an automatic launching and retracting buoy for deep-sea fishing nets. Background Technology
[0002] The automatic deployment and retrieval buoy for deep-sea fishing nets is a high-tech device used in deep-sea fishing operations. It mainly consists of a buoy body, an automatic deployment and retrieval device, and a signal transmission system. The core function of the automatic deployment and retrieval buoy lies in its automatic deployment and retrieval device. During deep-sea fishing, fishermen can control the deployment and retrieval of the buoy via remote control or a preset program, greatly improving fishing efficiency. In addition, this buoy is equipped with a signal transmission system that can transmit information such as the buoy's position and depth to the receiving equipment on the fishing boat in real time, allowing fishermen to monitor the status of the fishing net at any time. The emergence of the automatic deployment and retrieval buoy for deep-sea fishing nets has reduced the workload of fishermen and improved fishing efficiency.
[0003] In deep-sea fishing operations, the position of traditional fishing nets can be shifted due to complex ocean currents, making it difficult to accurately retrieve them. The traditional method of manually adjusting the buoys is not only time-consuming and labor-intensive, significantly reducing work efficiency, but also increases the rate of catch escape due to untimely adjustments. Furthermore, once the buoys shift, they may not be detected by the fishing boats in time, leading to entanglement and affecting the safe operation of the fishing boats, resulting in economic losses.

A bracket is fixedly connected to the top outer side of the main buoy, and a power storage mechanism is fixedly connected to the top of the bracket and the center of the top of the main buoy. A wireless controller is fixedly connected to the front of the power storage mechanism. Line retrieval mechanisms are fixedly connected to both sides of the top of the main buoy, and a net connecting mechanism is movably connected to the outer side of the line retrieval mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model incorporates a rotating base, a rotating motor, and a winding roller. The rotating motor drives the winding roller to rotate, retracting or extending the connecting line to retrieve and extend the small buoy, thus improving work efficiency.

A wireless controller 4 is fixedly connected to the front of the power storage mechanism 3. The line retraction mechanism 5 is fixedly connected to both sides of the top of the main buoy 1. The net connecting mechanism 6 is movably connected to the outer side of the line retraction mechanism 5.
[0025] Specifically, the energy storage mechanism 3 includes a solar panel 301, a battery 302, and a warning light 303. The solar panel 301 is fixedly connected to the top of the bracket 2, the battery 302 is fixedly connected to the top center of the main buoy 1, and the warning light 303 is fixedly connected to the top of the solar panel 301. The solar panel 301 generates electricity and stores it in the battery 302. At night, the warning light 303 is turned on to identify the location and avoid collisions.
[0026] Specifically, the take-up and release mechanism 5 includes a rotating base 501, a rotary motor 502, a winding roller 503, a connecting line 504, a partition 505, and a guide roller 506. The rotating base 501 is fixedly connected to the inner side of the top two sides of the main buoy 1. The rotary motor 502 is fixedly connected to the front of the rotating base 501. The winding roller 503 is fixedly connected to the output shaft of the rotary motor 502. Two sets of winding rollers 503 are provided. The rotary motor 502 drives the winding roller 503 to rotate, thereby taking up or releasing the connecting line 504 to take up and release the small buoy 602 and improve work efficiency.
[0027] Specifically, the outer side of the winding roller 503 is fixedly connected to one end of the connecting line 504. The connecting line 504 is fixedly connected to a partition 505, which can divide the connecting line 504 into two sections so that the two winding rollers 503 can perform winding and unwinding operations respectively.
[0028] Specifically, guide rollers 506 are fixedly connected to the outer sides of the top of the main buoy 1. The guide rollers 506 are in close contact with the connecting line 504, and the guide rollers 506 can prevent the connecting line 504 from rubbing against the main buoy 1 and causing wear.
[0029] Breakage reduces service life.
[0030] Specifically, the net connection mechanism 6 includes an upper connecting ring 601, a small buoy 602, a lower connecting ring 603, and a reflector 604.

The upper connecting ring 601 connects the small buoy 602 to the connecting line 504, and the lower connecting ring 603 connects the small buoy 602 to the net, thereby moving the net.
[0031] Specifically, a reflector 604 is fixedly connected to the outside of the small buoy 602. The reflector 604 reflects light or ambient light, allowing the fishing boat crew to observe the position of the small buoy 602 and the fishing nets, thus avoiding affecting the operation of the fishing boat.
[0032] Working principle: First, the upper connecting ring 601 connects the small buoy 602 to the connecting line 504, and the lower connecting ring 603 connects the small buoy 602 to the fishing net, driving the fishing net to move. When it is necessary to retrieve or deploy the small buoy 602, the rotary motor 502 drives the winding roller 503 to rotate, retrieving or deploying the connecting line 504 to retrieve or deploy the small buoy 602, improving work efficiency. The partition 505 can divide the connecting line 504 into two sections, allowing the two winding rollers 503 to perform retrieval and deployment work separately. At the same time, the guide roller 506 can prevent the connecting line 504 from rubbing against the main buoy 1, causing wear and breakage, thus improving service life. The solar panel 301 generates electricity and stores it in the battery 302. At night, the warning light 303 is turned on to identify the location and avoid collisions. At the same time, the reflector 604 reflects light or ambient light, allowing the fishing boat crew to observe the position of the small buoy 602 and the fishing net, avoiding affecting the operation of the fishing boat.
