Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fish fry catching, in particular to a fish fry catching device for fish fry breeding. Background Art
[0002] Fish fry harvesting is a multifunctional activity that aims to increase aquaculture production, maintain ecological balance, promote scientific research and support commercial sales. By moving wild fish fry into aquaculture environments, growth conditions can be controlled and aquaculture production can be increased. At the same time, the number of specific fish species in the ecosystem is managed to avoid their impact on other species. Scientists use captured fish fry to study their ecological, behavioral and physiological characteristics and improve technology and protection measures. In ecological protection projects, fish fry can be used to transfer endangered species or establish new populations. Commercial sales are an important motivation, but the law must be followed to protect the sustainability of wild populations. Fish fry harvesting involves farming, ecological management, scientific research and commercial interests, and ecological impacts must be considered comprehensively to ensure sustainability and rationality.
[0003] Traditional fry fishing gear for fish fry breeding consists of several key components. The first is the net bag or basket, which are the main tools for catching and collecting fry, usually made of soft but strong materials to ensure that the fry are not damaged. The second is the float or buoy, which supports the net bag or basket, allowing it to float on the water surface and remain stable. Ropes or rigging connect these components to facilitate operation and control of the position and movement of the fishing gear. The anchor acts as a fixing device, usually by fixing it to the bottom of the water to prevent drifting. In some cases, enforcement tags are also required to comply with fishing restrictions and regulations.
[0004] However, the traditional fish fry catching device is relatively simple in structure. It cannot effectively and actively attract fish fry to approach during fishing, which will lead to a certain degree of reduction in fishing efficiency. This means that it is impossible to catch a specified number of fish in a certain period of time, and it is impossible to specifically attract and catch specific types of fish fry. The lack of a fish trapping mechanism means that the device cannot effectively trap the captured fish fry, which can easily cause the fish fry to escape from the device, resulting in the loss and waste of fishing results. In addition, the lack of a fish attracting mechanism means that it is impossible to attract fish fry to gather at a specific time or place, which limits the controllability and efficiency of fishing. Therefore, a fish fry catching device for fish fry breeding is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 3The utility model provides an embodiment: a fry catching device for fry breeding, comprising a buoyancy barrel 1, a conical hole 15 is provided inside the buoyancy barrel 1, a rotating column 14 is threadedly connected inside the buoyancy barrel 1, a conical hole 15 is provided inside the buoyancy barrel 1, a handle 4 is fixedly connected to the top of the rotating column 14, a hollow column 12 is provided at the bottom of the rotating column 14, a bait storage tube 13 is fixedly connected inside the hollow column 12, a circular arc hole 16 is provided inside the hollow column 12, a connecting component is provided on the outer wall of the buoyancy barrel 1, and the connecting component includes a material storage frame 2, and one side of the material storage frame 2 is fixedly connected to the outer wall of the buoyancy barrel 1;
[0032] Specifically, the tapered hole 15 on the outer wall of the buoyancy barrel 1 is designed to be large on one side and small on the other side, providing a passage for fish to enter, but as the opening becomes smaller, once the fish enters, it is difficult to escape through the smaller opening. The arc hole 16 set on the hollow column 12 inside the buoyancy barrel 1 takes into account the safety of the fish, avoiding scratches or other injuries to the fish, and at the same time provides the fish with a safe passage to the inside of the buoyancy barrel 1. The coordinated design of the tapered hole 15 and the arc hole 16 achieves a double effect of trapping the fish, on the one hand ensuring that the fish is difficult to escape, and on the other hand ensuring the safety of the fish entering and staying, effectively capturing the target fish while minimizing the damage to them, providing a more humane and effective fishing solution.
[0033] Reference Figure 2 A sliding block 6 is slidably connected inside the material storage frame 2, a button 5 is fixedly connected to the top of the sliding block 6, a wedge block 8 is fixedly connected to the side walls of the sliding block 6, a first spring 7 is arranged on one side inside the sliding block 6, and one end of the first spring 7 is fixedly connected to the other side of the sliding block 6.
[0034] Specifically, first, the operator presses the clamping button 5 to fix the wedge block 8 in place. There is a first spring 7 on one side of the wedge block 8 to help maintain the clamping state. Then, open the storage frame 2, put in the required lead blocks or floats, and adjust the water depth and the characteristics of the fishing target as needed. By adjusting the position of the float and the lead block, it can be suspended at different water depths. During the whole process, the clamping and release of the wedge block 8 are achieved by operating the button 5, and the placement and adjustment of the lead block or float are achieved through the storage frame 2, thereby realizing the water depth adjustment function of the device, enhancing its flexibility and applicability to meet different fishing needs and water conditions.
[0035] Reference Figure 1 and Figure 2 A connecting block 9 is slidably connected to the inside of the material storage frame 2, a support plate 3 is fixedly connected to the side wall of the connecting block 9, a sliding plate 10 is fixedly connected to the side wall of the connecting block 9, the outer wall of the sliding plate 10 slides inside the material storage frame 2, a second spring 11 is provided at the bottom of the sliding plate 10, and the other end of the second spring 11 is fixedly connected to the inside of the material storage frame 2.
[0036] Specifically, the operator then turns the handle 4 to drive the rotating column 14 to rotate. The outer wall of the rotating column 14 is provided with threads, which cooperate with the threads inside the buoyancy barrel 1, so that the rotating column 14 can be screwed out of the interior of the buoyancy barrel 1 after being subjected to force. At the same time, the hollow column 12 at the bottom of the rotating column 14 will also be raised. This design allows the operator to easily extract the whole. The hollow column 12 is not fixed, so the operator can add corresponding bait to it to attract designated fry for fishing. This step enables the fishing device to have the function of adding bait, thereby improving the fishing efficiency and targeting.
[0037] Working principle: When using the fish fry catching device for fish fry breeding, the operator first clamps the button 5 to bring the two buttons 5 closer to each other, and the wedge blocks 8 are clamped together by the force applied to the button 5. Since the first spring 7 is provided on one side of the wedge block 8, the wedge block 8 can be taken out by tightening the first spring 7, and then the lead block or the float block can be put into the interior of the storage frame 2, and the float plate and the lead block can be matched with each other to achieve the effect of suspending them at different water depths, thereby achieving the effect of selecting the horizontal plane for different fish swimming. Then, the operator turns the handle 4, and the rotation of the handle 4 drives the rotating column 14 to rotate. Since the outer wall of the rotating column 14 is provided with a thread, and the inside of the buoyancy barrel 1 is also provided with a thread, the rotating column 14 is subjected to force to be screwed out of the buoyancy barrel 1. At the same time, the hollow column 12 at the bottom of the rotating column 14 can also be lifted out as a whole. At the same time, the hollow column 12 at the bottom of the rotating column 14 is not fixed. Then, corresponding bait can be added to the bait storage tube 13 to attract designated fry for fishing. After completing the above content, the buoyancy tube is placed in the water, and the conical hole 15 opened on the outer wall of the buoyancy barrel 1 is convenient for the fish to swim in. Since the cone is large on one side and small on the other side, it is not easy for the fish to swim out after swimming in. Then, an arc hole 16 is also opened inside the hollow column 12. Because one side of the arc hole 16 is set to an arc shape, it will not scratch the fish. At the same time, the cooperation between the conical hole 15 opened in the buoyancy barrel 1 and the arc hole 16 opened in the hollow column 12 achieves a double effect of trapping the fish inside the buoyancy barrel 1.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
