[0023] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.
[0024] like Figures 1 to 3 As shown, the utility model discloses a fish trapping cage, comprising a cage body 1, wherein at least one side of the cage body 1 has an open area 2 for fish to enter the cage body 1, and the cage body 1 is connected to a cage door assembly 3 capable of opening and closing the open area 2, the cage door assembly 3 comprises a movable frame 31, and a flexible net 6 arranged between the upper part of the cage body 1 and the movable frame 31, a locking mechanism 4 capable of locking the movable frame 31 above the open area 2 and unlocking the movable frame 31 from above the open area 2 is arranged between the upper part of the cage body 1 and the movable frame 31, and a reset mechanism 5 capable of driving the movable frame 31 to slide downward to close the open area 2 is also arranged on the cage body 1.
[0025] The cage body 1 can provide the necessary stability and volume for the cage to accommodate the captured fish. At least one side of the cage body 1 has an open area 2 for the fish to enter the cage body 1, which serves as a passage for the fish to enter the cage. The movable frame 31 slides in the up-down direction, and the locking mechanism 4 can lock the movable frame 31 after it slides upward to open the open area 2 for the fish to enter the cage. The reset mechanism 5 can drive the movable frame 31 to slide downward to close the open area 2 after the locking mechanism 4 releases the lock on the movable frame 31, thereby cooperating with the flexible net 6 to cover the open area 2 to achieve the purpose of trapping the fish in the cage. The flexible net 6 is specifically a mesh woven or constructed of a soft and elastic material, and nylon, polyester fiber, etc. can be selected as its material. The flexible net 6 is not easily damaged in the complex underwater flow environment, and can effectively block the open area 2 after the movable frame 31 falls to prevent the fish from escaping.
[0026] Compared with the traditional semi-enclosed fish cage, the cage has an open area 2 on one or more sides of the cage body 1 for fish to enter the cage body 1, which provides a more natural entry and exit path for the fish and increases their willingness to approach and enter the cage body 1; by setting a locking mechanism 4 that can lock the movable frame 31 after the movable frame 31 slides upward, and a reset mechanism 5 that can drive the movable frame 31 to slide downward, it is possible to control the opening and closing of the open area 2 without alerting the fish. At the same time, the user can capture fish of a specific size or type more specifically according to actual needs and fishing strategies, reduce the accidental capture of non-target species, and improve the capture efficiency; by setting the flexible net 6, the volume of the fish cage can be reduced, making the fish cage compact and easy to store and transport; at the same time, by covering the open area 2 with the flexible net 6, the damage to the fish during the fishing process is less, reducing the stress response of the fish during the fishing process.
[0027] The cage body 1 has a bottom surface 13 and a top surface 14 . A plurality of support rods 17 are disposed between the bottom surface 13 and the top surface 14 . Open areas 2 are disposed between adjacent support rods 17 .
[0028] In the embodiment, the openings formed around the adjacent support rods 17 are provided with the open areas 2 between the adjacent support rods 17, so that the cage body 1 has multiple open areas 2 for fish to enter the cage body 1, so that the cage body 1 is open and unobstructed all around, which reduces the vigilance of fish and alleviates the instinctive avoidance behavior of fish for enclosed spaces.
[0029] In the embodiment, four support rods 17 are arranged at the four corners of the rectangular cage body 1. A stable frame is formed by the four support rods 17, providing a solid basic structure for the cage. The support rods 17 are evenly distributed, which can make the weight distribution of the entire cage more balanced and ensure the stability of the cage underwater. The open area 2 is arranged between two adjacent support rods 17, so that the cage has open areas on all four sides, allowing fish to easily enter the cage from any direction, enhancing the attractiveness of the cage to fish in the surrounding waters, and also avoiding the crowding caused by a single open area.
[0030] The movable frame 31 is provided with a sliding sleeve 32 , and the sliding sleeve 32 is slidably connected to the support rod 17 .
[0031] By disposing the sliding sleeve 32 on the movable frame 31 , the sliding sleeve 32 is slidably connected to the support rod 17 , so that the movable frame 31 can slide up and down along the support rod 17 .
[0032] The bottom surface 13 and / or the top surface 14 is mesh-shaped.
[0033] The bottom surface 13 and / or the top surface 14 is arranged in a mesh shape, thereby reducing the vigilance of fish.
[0034] In the embodiment, the bottom surface 13 and / or the top surface 14 include a light-transmitting opening 15 and a blocking net 16 covering the light-transmitting opening 15. The provision of the light-transmitting opening 15 can reduce the vigilance of the fish, and the blocking net 16 provided on the light-transmitting opening 15 can prevent the fish from escaping directly through the light-transmitting opening 15 without affecting the light transmission, and also prevent other small aquatic organisms or impurities from entering the cage to interfere.
[0035] The locking mechanism 4 includes a limiting hole 311 provided on the movable frame 31, and a limiting pin 41 that can be inserted into the limiting hole 311 when the movable frame 31 is raised above the open area 2. A first elastic member 46 that can press the limiting pin 41 toward the limiting hole 311 is provided between the limiting pin 41 and the cage body 1. The locking mechanism 4 also includes a first traction rope 42 that can drive the limiting pin 41 to disengage from the limiting hole 311.
[0036] The limiting hole 311 is arranged on the movable frame 31 and cooperates with the limiting pin 41, so as to ensure that the movable frame 31 can be locked on the upper part of the cage body 1. Locking can be achieved by the cooperation between the limiting hole 311 and the limiting pin 41, and the structure is simple and practical. The first elastic member 46 can press the limiting pin 41 toward the limiting hole 311, so that the limiting pin 41 can be inserted into the limiting hole 311 and is not easy to be accidentally withdrawn. The first traction rope 42 is connected to the limiting pin 41. By external operations such as pulling the first traction rope 42, the limiting pin 41 can be disengaged from the limiting hole 311, thereby releasing the locking state of the movable frame 31.
[0037] A sliding seat 43 is provided at the upper part of the cage body 1, and the limit latch 41 is slidably connected to the sliding seat 43. The lower part of the sliding seat 43 is rotatably connected to an unlocking rod 44, and the unlocking rod 44 is movably connected to the limit latch 41. One end of the first traction rope 42 is connected to the unlocking rod 44.
[0038] In the embodiment, the sliding seat 43 has a limiting sleeve 431 sleeved on the outside of the limiting latch 41. By installing the sliding seat 43 on the upper part of the cage body 1, the limiting sleeve 431 thereon is sleeved around the limiting latch 41, ensuring that the limiting latch 41 remains stable during the sliding process to avoid deviation or shaking; in the embodiment, the limiting latch 41 is provided with an unlocking groove 45 for the unlocking rod 44 to extend into, and the unlocking rod 44 is rotatably connected to the sliding seat 43 through the lower part, and the upper part is connected to the limiting latch 41 through the unlocking groove 45. When the first traction rope 42 pulls the unlocking rod 44, the unlocking rod 44 rotates, thereby abutting against the unlocking groove 45 of the limiting latch 41 and pushing the limiting latch 41 to move, thereby pulling the limiting latch 44 out of the limiting hole 311, and realizing the unlocking of the movable frame 31.
[0039] In the embodiment, the movable frame 31 is provided with an extension plate extending upward, the limiting hole 311 is provided on the extension plate, and a handle is provided on the upper part of the extension plate. The setting of the extension plate allows the limiting hole 311 to better cooperate with the limiting latch 41. The setting of the handle allows the user to more conveniently slide the movable frame 31 upward to connect with the locking mechanism 4 to lock the movable frame 31.
[0040] In the embodiment, the upper part of the cage body 1 is further provided with a drawstring opening 11 for the first traction rope 42 to extend out, the connection between the first traction rope 42 and the unlocking rod 44 is higher than the drawstring opening 11, and a first guide member 12 capable of reducing the friction between the traction member and the drawstring opening 11 is provided between the unlocking rod 44 and the drawstring opening 11.

[0046] In the embodiment, the support rod 17 is detachably connected to the bottom surface 13, and the support rod 17 is detachably connected to the top surface 14. By detachably connecting the support rod 17 to the top surface 14 and the bottom surface 13, the support rod 17 can be quickly disassembled and stored, which is convenient for transportation and storage.
[0047] The lower side of the movable frame 31 is provided with a water dividing blade.
[0048] In the embodiment, the water-dividing blade is specifically to set the lower part of the movable frame 31 into a V-shape or a U-shape. The V-shape or U-shape edge design of the lower part of the movable frame 31 can effectively cut the water flow during the falling process of the movable frame 31, reduce the resistance of the water flow to the movable frame 31, and enable the sliding plate 31 to fall faster to close the open area 2, thereby achieving rapid capture.
[0049] The fish trapping cage also includes a graphic information acquisition module capable of detecting whether there is a fish entering the cage body 1.
[0050] The graphic information acquisition module is specifically a waterproof camera or other equipment, which continuously captures the real-time images in the cage and provides the user with direct visual feedback of the fish entering and moving. The user can accurately judge the best time to close the cage according to the gathering of fish in the cage.
[0051] When using the cage, firstly, according to the target fish species, a suitable bait is selected and placed in the cage. Then, an area where fish are active is selected, the cage is steadily placed in the water, and the first traction rope 42 is held, and the situation inside the cage is observed by naked eyes or by a graphic information acquisition module, and the first traction rope 42 is pulled so that the locking mechanism 4 unlocks the movable frame 31, and the reset mechanism 5 drives the movable frame 31 to slide downward, so that the flexible net 6 covers the open area 2, thereby completing a fish trapping.
