[0002] In the current thriving aquaculture industry, efficient and reliable fishing technology plays a key role in the sustainable growth and economic benefit improvement of the industry. Traditional aquaculture fishing methods have many drawbacks.
[0003] In terms of equipment, traditional fishing nets have simple structures and uneven force distribution during the netting process, which can easily cause net body rupture and fish escape. This problem is more prominent when fishing large fish groups or encountering complex water environments, resulting in resource waste and economic losses. In addition, the post-fishing fish transfer method is also relatively backward, usually using manual fish retrieval and then transporting to the designated location, which not only has low efficiency, but also easily causes damage to the fish body, reduces the survival rate and quality of the fish, and affects subsequent sales.
[0004] For the above related technologies, the inventors found that the following defects exist: Many existing fishing devices still rely on a large amount of manual operation to pull the net. Workers need to spend a lot of physical effort and time to pull the fishing net, which not only has low efficiency, but also has high labor costs. In large-scale fishing operations, the limitations of manpower are more obvious, and it is difficult to meet the needs of rapid and efficient fishing. Some fishing devices on the market lack a reasonable tension transmission structure when the net is pulled, resulting in uneven force distribution of the fishing net. This makes the fishing net prone to skew and local overloading during the netting process, thereby increasing the risk of fishing net rupture and causing fish to escape, resulting in economic losses.

[0030] Further explanation is needed:
[0031] The net collecting assembly 1 is mainly composed of a top cover 101, a bearing block 102, a lead screw 103, a servo motor 104, a net collecting block 105, a cable fixing ring 106, a cable body 107, a pulley seat 108, a motor mounting cylinder 109, and a sliding rail 110. The bearing block 102 is connected with the fishing boat hook cable and plays a supporting role for the whole assembly. The servo motor 104 drives the lead screw 103 to rotate. The lead screw 103 is threadedly connected with the net collecting block 105 and can convert the rotary motion of the motor into the linear motion of the net collecting block 105 along the direction of the lead screw 103. The cable fixing ring 106 is fixed on the net collecting block 105 and connected with the cable body 107. The pulley seat 108 assists the cable movement. The motor mounting cylinder 109 and the sliding rail 110 ensure the stable movement of the net collecting block 105. The core function is to realize automatic net collecting. By controlling the servo motor 104, the net collecting speed and intensity can be accurately adjusted, which greatly saves manpower. The cable body 107 is uniformly pulled by the net collecting block 105, ensuring that the fishing net is balanced during the net collecting process, preventing the net body from being skewed or broken, and ensuring the smooth progress of the fishing operation. It can also prolong the service life of the fishing net. The pulley seat 108 reduces the friction of the cable, making the cable movement smoother and further improving the stability of the net collecting.
[0032] The fish conveying assembly 2 comprises a support assembly 201, a positioning ring 202, a reinforcing rib 203, a fishing net fixing ring 204 and a funnel 205. The support assembly 201 is fixed at the bottom of the motor mounting cylinder 109 and serves to support the whole fish conveying assembly 2. The positioning ring 202 and the reinforcing rib 203 enhance the structural stability. The reinforcing rib 203 connects the positioning ring 202 and the fishing net fixing ring 204 and disperses the fishing net tension. The funnel 205 is provided with an adapter at the bottom. The main function of the fish conveying assembly 2 is to guide and transfer the caught fish. During fishing, the funnel 205 guides the fish to gather at the bottom, which is convenient for collection. After fishing, the adapter at the bottom of the funnel 205 is communicated with the fish pump pipeline, so that the fish can be quickly transferred to the designated position, such as the fish hold of the ship. The fish conveying assembly 2 avoids the complicated manual fishing and saves time and labor. The fish conveying assembly 2 reduces the damage of the fish during the transfer process and ensures the quality of the fish. The distance between the adjacent support rods of the support assembly 201 is greater than the width of the fish. The support assembly 201 does not hinder the fish from entering the funnel 205 and reduces the water flow resistance, so that the fishing device moves more smoothly in the water and the fishing efficiency is improved.
[0033] The working principle of the above embodiment is as follows:
[0034] Firstly, the whole fishing device is installed on the fishing boat and fixedly connected with the hook cable on the fishing boat through the bearing block 102, so that the preliminary fixation of the device is completed and the device is ensured not to fall off during fishing. Meanwhile, the fishing net body 3 is unfolded and the frame thereof is hinged to one side of the reinforcing rib 203, so that the fishing operation is prepared.
[0035] Secondly, the servo motor 104 is started, and the output end of the servo motor 104 drives the screw rod 103 to rotate. Since the screw rod 103 is threadedly sleeved with the net collecting block 105, the rotary motion of the screw rod 103 is converted into the linear motion of the net collecting block 105 along the direction of the screw rod 103. In this process, the slide rail 110 on the inner wall of the motor mounting cylinder 109 guides and stabilizes the net collecting block 105, so that the net collecting block 105 can only move smoothly on the screw rod 103.
[0036] Then, with the movement of the net collecting block 105, the cable body 107 fixedly connected with the cable fixing ring 106 on the top of the net collecting block 105 is started to be pulled. The other end of the cable body 107 is fixedly connected with the frame of the fishing net body 3, so that the tension of the cable body 107 drives the fishing net body 3 to gradually fold and trap the fish. In this process, the pulley seat 108 movably connected with one side of the cable body 107 guides the cable and reduces the friction, so as to ensure the smooth movement of the cable.
[0037] Next, when the fishing net body 3 successfully traps the fish, the fish gathers to the bottom along the funnel 205 of the fish conveying assembly 2. At this time, the adapter at the bottom of the funnel 205 is in a closed state to prevent the fish from escaping.
[0038] Finally, after the fishing operation is completed, the adapter at the bottom of the funnel 205 is connected with the pipeline of the fish pump, the fish pump is started, and the caught fish is quickly and efficiently transferred to the designated fish hold or other position on the ship through the pipeline, thereby completing the whole fishing process.
[0039] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
