[0027] Example 1
[0028] Please see Figure 1-6As shown, a fish trapping device includes a trapping box 1 and a mounting frame 22. The trapping box 1 has trapping openings 2 on both sides of its exterior. A bait box 3 is installed inside the trapping box 1. Adjustment components are installed on both sides of the interior of the trapping box 1. An outlet 7 is opened at the bottom of the trapping box 1, and a collection net 8 is detachably connected to the bottom of the outlet 7. A traction rope 21 is fixedly connected to the top of the trapping box 1. A transmission component is installed inside the trapping box 1. A disassembly / assembly component is installed at the bottom of the outlet 7. The adjustment components include a limiting rod 4. The interior sides of the trapping box 1 are respectively and staggeredly fixedly connected to… There are two sets of limiting rods 4, with a first adjusting plate 5 and a second adjusting plate 6 symmetrically slidably connected to the outside of each set of limiting rods 4. The transmission assembly includes a bidirectional lead screw 9 and a transmission unit. The bidirectional lead screw 9 is divided into two sets and is alternately rotatably connected to the inside of the trap box 1. The two sets of first adjusting plates 5 and second adjusting plates 6 are symmetrically connected to the outside of the corresponding bidirectional lead screw 9 through lead screw and nut pairs. The two sets of first adjusting plates 5 and second adjusting plates 6 can move synchronously through the transmission unit. The transmission unit includes a protective cover 10, which is fixedly connected to the trap box 1. Externally, inside the protective cover 10, two sets of bidirectional lead screws 9 are respectively fixedly connected to two motors 11. One end of each of the two bidirectional lead screws 9 on one side extends to the outside of the trap box 1 and is fixedly connected to the output end of the corresponding motor 11. Synchronous pulleys 12 are fixedly connected to the outside of the two sets of bidirectional lead screws 9 on both sides. The two sets of synchronous pulleys 12 are connected by two synchronous belts 13. The disassembly and assembly assembly includes a fixing post 14, which is symmetrically fixedly connected to the outside of the outlet 7. Limit brackets 1 are slidably connected to both sides of the outside of the fixing post 14. 5. Hanging ropes 16 are fixedly connected to both sides of the top of the collection net 8. The hanging ropes 16 can be limited by the limiting frame 15. One end of the two limiting frames 15 extends into the interior of the fixed column 14 and is fixedly connected to the inclined block 17. The interior of the fixed column 14 is slidably connected to the push rod 20 that cooperates with the inclined block 17. The inner side of the two limiting frames 15 extends into the interior of the fixed column 14 and is fixedly connected to the sliding rod 18. The sliding rod 18 is slidably connected to the inner wall of the fixed column 14. A spring 19 is provided on the outside of the sliding rod 18 and between the limiting frame 15 and the fixed column 14.
[0029] During operation, the trap box 1 is first submerged in water using the traction rope 21. The bait box 3 releases an odor to lure fish into the trap box 1 through the trap opening 2. Because the trap opening 2 narrows from the outside in, fish cannot easily escape once inside, thus achieving fish trapping. When trapping fish of different sizes, two motors 11 are simultaneously activated via an external controller. The output of the motors 11 drives the corresponding bidirectional lead screw 9 and synchronous pulley 12 to rotate. Under the transmission of the two synchronous pulleys 12 and synchronous belt 13, the two sets of bidirectional lead screws 9 on both sides rotate synchronously. Thus, the two sets of bidirectional lead screws 9 drive the corresponding first adjusting plate 5 and second adjusting plate 6 to slide and adjust under the limit of the limiting rod 4. Therefore, the diameter of the trap opening 2 can be arbitrarily adjusted by the cooperation of the first adjusting plate 5 and the second adjusting plate 6. When the trap opening 2 is adjusted to a smaller size, smaller fish can be caught; when the trap opening 2 is adjusted to a larger size, larger fish can be caught. This improves the fishing accuracy and flexibility of the device and avoids the problem of fish being caught in the trap. This eliminates the hassle of re-sorting the fish after harvesting, thus reducing the workload of the staff. Once the fishing requirements are met, the bait box 1 can be retrieved using the tow rope 21. The water inside the bait box 1 can be drained through the mesh of the collection net 8, allowing all the fish to enter the collection net 8. Then, press the push rods 20 on both sides to push the two inclined blocks 17 to move to both sides, thereby opening the limit frames 15 on both sides. At the same time, the sliding rod 18 slides outward from the fixed column 14 and stretches the spring 19. Then, the hanging ropes 16 on both sides can be removed. Release the push rods 20 again, and the limit frames 15 can be reset under the rebound force of the spring 19, thus completing the disassembly of the collection net 8. This facilitates the centralized processing of the fish inside the collection net 8, eliminating the need to dump the fish onto the ground or into the boat, thus avoiding the hassle of re-collecting the fish. After the collection net 8 containing fish is removed, an empty collection net 8 can be quickly reinstalled using the same principle, facilitating the rapid deployment of the bait box 1 into the water, thereby effectively improving the efficiency of fish harvesting.
[0030] Both motors 11 are electrically connected to an external controller. One end of the push rod 20 extends to the outside of the fixed column 14 and is fixedly connected to a disc. The ends of the two limit brackets 15 away from the inclined block 17 are attached to the outer wall of the fixed column 14 after retraction.
[0031] Through the above technical solution, the two motors 11 can be quickly controlled by the staff through the external controller, so that the two motors 11 can run synchronously.
[0032] Example 2
[0033] Please see Figure 7As shown in the first embodiment, as another implementation of the present invention, the top of the mounting bracket 22 is fixedly connected to a fixing bracket 23, a pulley is rotatably connected to one side of the inner side of the fixing bracket 23, and bolts 24 are threadedly connected to both sides of the outer side of the mounting bracket 22.
[0034] During operation, by installing the mounting frame 22 with two bolts 24 on the side of the hull or the fishing shore, and laying the towing rope 21 on the pulley, the trap box 1 can be easily pulled manually or by a traction machine, which further improves the working efficiency of the device.
[0035] Working principle: First, the bait box 1 is submerged in water via the traction rope 21. The bait box 3 releases an odor to lure fish into the bait box 1 through the bait opening 2. Because the diameter of the bait opening 2 narrows from the outside to the inside, it is difficult for fish to swim out and escape after entering, thus achieving the goal of trapping fish. When it is necessary to trap fish of different sizes, two motors 11 are started simultaneously via an external controller. The output of the motors 11 drives the corresponding bidirectional lead screws 9 and synchronous pulleys 12 to rotate. Furthermore, under the transmission of the two synchronous pulleys 12 and the synchronous belt 13, the two sets of bidirectional lead screws 9 on both sides can rotate synchronously. The device moves, thereby driving the corresponding first adjusting plate 5 and second adjusting plate 6 to slide and adjust under the limit of the limiting rod 4 through two sets of bidirectional lead screws 9. This allows for arbitrary adjustment of the diameter of the trap opening 2 through the cooperation of the first adjusting plate 5 and the second adjusting plate 6. A smaller trap opening 2 can catch smaller fish, while a larger one can catch larger fish, improving the accuracy and flexibility of the device. It also avoids the hassle of re-sorting fish after fishing, thus reducing the workload of the staff. After fishing is completed, the trap box 1 can be retrieved using the traction rope 21 and collected by the collection net 8. The mesh allows water to drain from the trap box 1 and draws all fish into the collection net 8. Pressing the push rods 20 on both sides pushes the two inclined blocks 17 to move to the sides, causing the limiting frames 15 on both sides to open. Simultaneously, the sliding rod 18 slides outwards towards the fixed post 14, stretching the spring 19. The hanging ropes 16 on both sides can then be removed. Releasing the push rods 20 again allows the limiting frames 15 to return to their original position under the restoring force of the spring 19, thus completing the disassembly of the collection net 8. This facilitates the centralized processing of the fish inside the collection net 8, eliminating the need to dump the fish onto the ground or into the boat, thereby avoiding... The device eliminates the hassle of recollecting fish, and after removing the fish-filled collection net 8, an empty collection net 8 can be quickly reinstalled using the same principle, facilitating the rapid deployment of the trap box 1 into the water. This effectively improves the efficiency of fish harvesting. An external controller allows for quick and easy control of the two motors 11, enabling them to operate synchronously. By mounting the frame 22 with two bolts 24 to the side of the boat or fishing shore, and laying the towing rope 21 on the pulley, the trap box 1 can be easily pulled manually or by a traction machine, further enhancing the working efficiency of the device.
