Description

Technical Field

[0001] This application relates to the field of aquatic fishing tools technology, and in particular to an aquatic product trapping device. Background Technology

[0002] Aquatic product trapping devices are devices specifically designed for catching aquatic economic animals such as fish, shrimp, and crabs. They are usually placed in near-shore waters. After a period of time, the aquatic product trapping devices are removed from the water, and the aquatic organisms are captured.

[0003] Aquatic product trapping devices typically consist of a cage and a mechanism to prevent aquatic products from escaping. In the prior art, the device to prevent aquatic products from escaping generally has a one-way door at the cage opening, making it difficult for aquatic products to swim out after entering. However, when the aquatic product trapping device is removed from the water, the existing one-way door is easily washed open by the water flow, allowing shrimp and crabs inside the cage to easily escape from the cage opening.

[0004] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0005] In view of the above problems, this utility model proposes an aquatic product trapping device that makes it difficult for aquatic organisms to escape.

[0006] To achieve the above objectives, the aquatic product trapping device proposed in this utility model includes:

[0007] The cage has a cavity inside, and the side wall of the cage has a trapping opening so that aquatic organisms can enter the cavity through the trapping opening;

[0008] A one-way door is rotatably connected to the cage body and is positioned corresponding to the trapping opening, allowing the one-way door to have a first position and a second position. In the first position, the one-way door is limited and abuts against the inner wall of the cage body, covering the trapping opening. When switching from the first position to the second position, the one-way door flips inward toward the cavity, opening the trapping opening.

[0009] A response component is fixedly connected to the one-way door, and the response component is configured to keep the one-way door in the first position; and to allow the one-way door to switch from the first position to the second position when aquatic organisms enter.

[0010] In one embodiment, the one-way door is rotatably connected to the side wall of the cage about a horizontal axis, and the one-way door is set at an angle to the vertical axis.

[0011] The response component includes a counterweight, which is disposed adjacent to the bottom of the one-way door.

[0012] In one embodiment, the cage body includes a cage body and a baffle protruding laterally from the side wall of the cage body. The cavity is located inside the cage body, and the one-way door is rotatably connected to the side wall of the cage body. The one-way door is located on the longitudinal projection surface of the baffle.

[0013] In one embodiment, the top of the one-way door is rotatably connected to the side wall of the cage body, and the one-way door extends obliquely from top to bottom into the cavity.

[0014] In one embodiment, the angle between the one-way door and the vertical axis is greater than or equal to 10° and less than or equal to 45°.

[0015] In one embodiment, the cage body includes an upper cage and a lower cage that are detachably connected, and the one-way door is located in the lower cage;

[0016] Both the upper cage and the lower cage have openings. When the cage is in use, the upper cage is connected to the lower cage, and the openings of the upper cage and the lower cage are opposite each other. The upper cage and the lower cage enclose the cavity. When the cage is in storage, the upper cage and the lower cage are stacked through the openings.

[0017] In one embodiment, the cross-sectional area of ​​the lower cage gradually increases from bottom to top, and / or the cross-sectional area of ​​the upper cage gradually increases from top to bottom, so that one of the upper cage and the lower cage can be accommodated within the other.

[0018] In one embodiment, the open end of the upper cage is provided with a first annular flange protruding laterally, and the open end of the lower cage is provided with a second annular flange protruding laterally. The first annular flange is engaged with the second annular flange longitudinally to form the enclosure.

[0019] In one embodiment, the aquatic product trapping device further includes a plurality of bait components, with at least one bait component provided on the top wall of the upper cage and at least one bait component provided on the bottom wall of the lower cage, the bait components being rotatably engaged with the upper cage or the lower cage;

[0020] The aquatic product trapping device also includes multiple one-way doors, which are arranged at circumferential intervals around the bait.

[0021] The side wall of the upper cage is provided with multiple fishing channels for attracting fish. The fishing channels are connected to the cavity and are arranged at intervals around the circumference of the bait.

[0022] In one embodiment, the inner sidewall of the cage is provided with a rotating member, and the inner sidewall of the one-way door is provided with a mating member. One of the rotating member and the mating member is provided with a rotating shaft, and the other is provided with a shaft hole that rotatably engages with the rotating shaft.

[0023] This aquatic product trapping device features a one-way door within the cage, allowing shrimp, crabs, and other aquatic organisms to freely enter the cavity when the device is placed in water. Furthermore, a return mechanism on the one-way door allows the organisms to overcome the force of the return mechanism and push the door to a second position—that is, the door flips inward, opening the trapping opening. After the organisms enter the cavity, the one-way door automatically returns to its first position under the action of the return mechanism. Because of this automatic return function, when the aquatic product trapping device is lifted out of the water, the water flow is unlikely to force open the one-way door, thus greatly reducing the risk of aquatic organisms escaping.

[0037] This utility model proposes an aquatic product trapping device 100.

[0038] In this embodiment of the utility model, please refer to Figures 1 to 5 The aquatic product trapping device 100 includes: a cage body 10, a one-way door 20 and a return component 30. The cage body 10 has a cavity 11 inside, and the side wall of the cage body 10 is provided with a trapping opening 12 so that aquatic organisms can enter the cavity 11 through the trapping opening 12.

[0039] A one-way door 20 is rotatably connected to the cage body 10 and is configured corresponding to the trapping opening 12, so that the one-way door 20 has a first position and a second position. In the first position, the one-way door 20 is limited to abutting against the inner side wall of the cage body 10 and covers the trapping opening 12. When switching from the first position to the second position, the one-way door 20 flips into the cavity 11 so that the trapping opening 12 is opened. A return member 30 is fixedly connected to the one-way door 20 and is configured to keep the one-way door 20 in the first position and to allow the one-way door 20 to switch from the first position to the second position when aquatic organisms enter.

[0040] The cage body 10 can be a net cage structure made of plastic or metal wire mesh, with an internal cavity 11 for accommodating aquatic animals. A trapping opening 12 is provided on one side wall of the cage body 10, which is a channel for aquatic animals such as shrimp and crabs to enter the cavity 11.

[0041] The one-way door 20 can be a baffle. The one-way door 20 is rotatably mounted on the cage body 10 around a horizontal or vertical axis. The size of the one-way door 20 matches the trapping opening 12 and is located inside the trapping opening 12. It has a first position and a second position. In the first position, the one-way door 20, under the action of the return member 30, abuts against the inner wall of the trapping opening 12, forming a limiting abutment, thereby closing the trapping opening 12 and preventing the one-way door 20 from opening outwards. Specifically, a limiting block 212 may protrude from the inner wall of the one-way door 20. In the first position, the limiting block 212 abuts against the inner wall of the cage body 10.

[0042] When aquatic organisms enter, they can push the one-way door 20 to overcome the force of the return member 30 and rotate it to the second position, that is, the one-way door 20 flips inward, so that the trapping port 12 is opened. After the aquatic organisms enter the cavity 11, the one-way door 20 automatically resets to the first position under the action of the return member 30.

[0043] The return element 30 can be a counterweight 31, a magnetic component, a spring, or an elastic sheet; there are no restrictions. However, when the return element 30 is a counterweight 31, the plane containing the one-way door 20 is set at an angle to the vertical axis, and the return element 30 is located on the side of the one-way door 20 away from the rotating connection. When the return element 30 is a spring or an elastic sheet, it is located between the one-way door 20 and the cage 10. Specifically, one end of the return element 30 is fixedly connected to the cage 10, and the other end is fixedly connected to the one-way door 20. When the one-way door 20 rotates from the first position to the second position, the return element 30 deforms to store elastic potential energy; after the aquatic organisms have completely entered the cavity 11, the return element 30 releases its elastic potential energy, driving the one-way door 20 to automatically return to the first position, thereby closing the trapping opening 12 and effectively preventing the aquatic organisms from escaping.

[0044] The aquatic product trapping device 100 of this utility model features a one-way door 20 on the cage body 10, allowing aquatic organisms such as shrimp and crabs to freely enter the cavity 11 when the device is placed in the water. Furthermore, a return element 30 is provided on the one-way door 20, enabling the aquatic organisms to overcome the force of the return element 30 and push the one-way door 20 to a second position when it enters, i.e., the one-way door 20 flips inward, opening the trapping opening 12. After the aquatic organisms enter the cavity 11, the one-way door 20 automatically returns to its first position under the action of the return element 30. Because the one-way door 20 has an automatic reset function, when the aquatic product trapping device 100 is lifted out of the water, the water flow is unlikely to force open the one-way door 20, thus greatly reducing the risk of aquatic organisms escaping.

[0045] In one embodiment, the one-way door 20 is rotatably connected to the side wall of the cage 10 about the horizontal axis, and the one-way door 20 is set at an angle to the vertical axis. The return member 30 includes a counterweight 31, which is disposed near the bottom of the one-way door 20.

[0046] In this embodiment, the one-way door 20 is rotatable around the horizontal axis. Initially, the one-way door 20 is located inside the cage 10 and is arranged at a certain downward angle relative to the horizontal axis. That is, the panel of the one-way door 20 is set at an angle to the vertical direction of the cage 10. This allows the one-way door 20 to automatically fall back and adhere to the trapping opening 12 under gravity after aquatic organisms push it in. It should be noted that the one-way door 20 can tilt from top to bottom towards the cavity 11 or towards the cavity 11. When the one-way door 20 tilts towards the cavity 11, the horizontal axis is located at the top of the one-way door 20; when the one-way door 20 tilts towards the cavity 11, the horizontal axis is located in the middle of the one-way door 20.

[0047] The response component 30 includes a counterweight 31, which is fixedly installed in the lower region of the one-way door 20, i.e., near the bottom of its free end. Through the gravity of the counterweight 31, the one-way door 20 can naturally droop and fit against the trap opening 12 without being pushed by an external force, thus achieving automatic closure.

[0048] The weight and installation position of the counterweight 31 can be adjusted according to the size, material and usage environment of the one-way door 20 to ensure that it has appropriate restoring force, so that it can be easily pushed open by aquatic organisms and can remain closed under the impact of water flow to prevent reverse opening.

[0049] Thus, compared to structures with elastic or magnetic recovery, the counterweight 31 has a simpler structure, is easier to manufacture and install, and its weight can be adjusted at any time according to the environment.

[0050] In some embodiments, the one-way door 20 is hollow, and the return component 30 also includes a collar 32 fixedly connected to the counterweight 31. The collar 32 is sleeved on the rib of the one-way door 20. The collar 32 can be a cable tie. In this way, the installation steps are simplified, the installation efficiency of the aquatic product trapping device 100 is improved, and the weight of the counterweight 31 can be adjusted at any time according to the environment.

[0051] In one embodiment, the cage 10 includes a cage body 13 and a baffle 14 that protrudes laterally from the side wall of the cage body 13. The cavity 11 is located inside the cage body 13. The one-way door 20 is rotatably connected to the side wall of the cage body 13. The one-way door 20 is located in the projection plane of the baffle 14 from top to bottom.

[0052] In this embodiment, the cage 10 includes a cage body 13 and a enclosure 14. The enclosure 14 protrudes laterally from the side wall of the cage body 13, specifically located on the side wall where the trapping opening 12 is provided.

[0053] The one-way door 20 is rotatably connected to the side wall of the cage body 13 via a pivot 211 and is located within the top-to-bottom projection plane of the enclosure 14. In other words, when viewed from the vertical direction, the entire structure of the one-way door 20 is located within the area covered by the enclosure 14, so that the one-way door 20 is shielded and protected by the enclosure 14.

[0054] In this structure, when the cage 10 is lifted or floats in the water, the enclosure 14, as a protruding structural member, first comes into contact with the water, bearing and dispersing most of the impact force of the water flow. This significantly reduces the water pressure acting on the one-way gate 20, preventing the one-way gate 20 from being blown open by the water flow and causing aquatic animals to escape. At the same time, this structure can also reduce the mechanical fatigue caused by the swinging of the one-way gate 20 due to the impact of the water flow.

[0055] In addition, the enclosure 14 can also serve as a gripping part. Its laterally protruding structure makes it easy for users to grip directly during handling, improving the convenience and safety of operation. The enclosure 14 can be made of the same or different materials as the cage body 13, preferably plastic or metal sheets, which have good structural strength.

[0056] In one embodiment, the top of the one-way door 20 is rotatably connected to the side wall of the cage body 13, and the one-way door 20 extends obliquely from top to bottom into the cavity 11.

[0057] In this embodiment, the top of the one-way door 20 is rotatably connected to the side wall of the cage body 13 via a pivot 211, specifically located at the upper edge of the trapping opening 12, allowing the one-way door 20 to rotate around a horizontal axis. The one-way door 20 extends inward from top to bottom, meaning its bottom is closer to the cavity 11 of the cage body 10 than its top. This structural design allows the one-way door 20 to naturally droop and conform to the trapping opening 12 when not subjected to external force, forming a closed state. Due to gravity, the one-way door 20 can open inward when pushed by aquatic organisms, and quickly fall back to the closed position after they pass through, thus achieving a reliable one-way entry effect.

[0058] Furthermore, the inclined one-way door 20 is less likely to be blown open by external forces during water flow impact or net lifting operations, and its low center of gravity structure also helps to improve escape prevention performance in conjunction with the enclosure 14. At the same time, the top connection method facilitates installation and maintenance and reduces structural complexity. In some embodiments, the side wall of the cage body 13 may or may not be in the same direction as the inclination of the one-way door 20, and no restriction is imposed here.

[0059] In one embodiment, the angle between the one-way door 20 and the vertical axis is greater than or equal to 10° and less than or equal to 45°.

[0060] In this embodiment, the angle between the one-way door 20 and the vertical axis can be 10°, 15°, 16°, 20°, 30°, 40°, or 45°. This angle setting not only ensures that the one-way door 20 can smoothly flip to the open state when aquatic organisms are pushed in, but also utilizes gravity and the action of the return member 30 to reliably return it to the closed state after the loss of external force. An appropriate tilt angle can also prevent the door from being accidentally opened due to water flow disturbance, thus improving the escape prevention effect of the entire trapping device.

[0061] If the angle between the one-way gate 20 and the vertical axis is too small, the one-way gate 20 tends to be close to a vertical state. Due to the small tilt angle, the effect of gravity is not obvious, and the ability of the gate to return to the closed state becomes weaker. When the water flow is disturbed or the net is lifted, the gate is more likely to be opened by the surging water or the backflow, increasing the risk of aquatic animals escaping.

[0062] If the angle between the one-way door 20 and the vertical axis is too large, the one-way door 20 will tend to be in a near-horizontal state or tilt too much inward, occupying the internal space of the cage 10, resulting in an increase in the overall volume and a reduction in the effective volume for accommodating aquatic products.

[0063] Reference Figure 2 and Figure 3In one embodiment, the cage body 13 includes an upper cage 131 and a lower cage 132 that are detachably connected, and a one-way door 20 is provided on the lower cage 132. Both the upper cage 131 and the lower cage 132 have an opening 135. When the cage body 10 is in use, the upper cage 131 is connected to the lower cage 132, and the openings 135 of the upper cage 131 and the lower cage 132 are opposite to each other. The upper cage 131 and the lower cage 132 enclose each other to form a cavity 11. When the cage body 10 is in storage, the upper cage 131 and the lower cage 132 are stacked through the openings 135.

[0064] In this embodiment, the cage body 13 includes an upper cage 131 and a lower cage 132. The upper cage 131 and the lower cage 132 are connected by a detachable structure, such as by means of buckles, threaded connections, plug-in connections, elastic locks, etc., to achieve quick assembly and disassembly.

[0065] Both the upper cage 131 and the lower cage 132 have an opening 135, that is, the bottom of the upper cage 131 and the top of the lower cage 132 have an opening structure, so that when in use, the opening 135 of the upper cage 131 and the opening 135 of the lower cage 132 are opposite to each other and connected to form a cavity 11 for containing aquatic organisms.

[0066] A one-way door 20 is installed on the lower cage 132 and is configured to cooperate with the trapping opening 12 on its side wall. When aquatic organisms enter the lower cage 132 from the outside, they enter the entire cavity 11 structure.

[0067] When stored, the upper cage 131 and the lower cage 132 can be detached and stacked relative to each other through their openings, i.e., one is inserted into the other, which greatly reduces the overall space occupied and makes it easy to carry, transport and store.

[0068] This embodiment combines structural rigidity, operational stability, and portability through modular and modular design.

[0069] In one embodiment, the cross-sectional area of ​​the lower cage 132 gradually increases from bottom to top, and / or the cross-sectional area of ​​the upper cage 131 gradually increases from top to bottom, so that one of the upper cage 131 and the lower cage 132 can be accommodated within the other.

[0070] In this embodiment, to facilitate convenient storage and nesting of the upper cage 131 and the lower cage 132, the cross-sectional area of ​​the lower cage 132 gradually increases from the bottom to the top, and / or the cross-sectional area of ​​the upper cage 131 gradually increases from the top to the bottom. Through the above structural design, one of the upper cage 131 and the lower cage 132 can be inserted into and housed inside the other, maximizing space utilization.

[0071] Preferably, the upper cage 131 and the lower cage 132 have the same shape, such as a frustum, square pyramid, or truncated cone, so that they can fit together perfectly when stored, avoiding structural interference and improving stacking stability. At the same time, the same shape also facilitates the use of universal molds, improving production efficiency.

[0072] In one embodiment, the upper cage 131 has a first annular flange 133 protruding laterally at the opening 135 end, and the lower cage 132 has a second annular flange 134 protruding laterally at the opening 135 end. The first annular flange 133 is engaged with the second annular flange 134 longitudinally to form a enclosure 14.

[0073] To enhance the stability and positioning accuracy of the upper cage 131 and the lower cage 132 in the connected state, a first annular flange 133 is laterally protruded at the open end 135 of the upper cage 131, and a second annular flange 134 is laterally protruded at the open end 135 of the lower cage 132. The first annular flange 133 is structurally opposite to the second annular flange 134.

[0074] The first annular flange 133 can be inserted and engaged with the second annular flange 134 in the longitudinal direction, so that the two form a reliable limiting connection structure in the vertical direction, thereby ensuring that the upper cage 131 and the lower cage 132 form a stable overall cavity 11 after connection.

[0075] Furthermore, the structure formed by the annular flange can also serve as the aforementioned enclosure 14. When the cage 10 is lifted and the water flow is strong, the structure can reduce the direct impact force of the water flow on the one-way door 20, and further prevent the one-way door 20 from being blown open.

[0076] In one embodiment, the aquatic product trapping device 100 further includes a plurality of bait elements 40, with at least one bait element 40 provided on the top wall of the upper cage 131 and at least one bait element 40 provided on the bottom wall of the lower cage 132, and the bait element 40 being rotatably engaged with the upper cage 131 or the lower cage 132.

[0077] The aquatic product trapping device 100 also includes multiple one-way doors 20, which are arranged at intervals around the bait 40 in a circumferential manner.

[0078] The side wall of the upper cage 131 is provided with multiple fishing channels 15 for attracting fish. The fishing channels 15 are connected to the cavity 11, and the multiple fishing channels 15 are arranged at intervals around the circumference of the bait 40.

[0079] The aquatic product trapping device 100 also includes multiple bait elements 40 for attracting aquatic organisms into the cage 10. The top wall of the upper cage 131 is provided with at least one bait element 40, and the bottom wall of the lower cage 132 is also provided with at least one bait element 40, so as to attract aquatic organisms with different habits to approach the trapping device.

[0080] The bait component 40 is rotatably snapped onto the upper cage 131 or the lower cage 132. The rotatable snap-fit ​​structure facilitates quick loading, unloading, and replacement of the bait, improving ease of use and adaptability. When storing the cage body 10, first remove the bait component 40 from the cage body 10, then remove the upper cage 131 from the lower cage 132, and finally store the upper cage 131 inside the lower cage 132 to achieve the storage function.

[0081] Furthermore, the device also includes multiple one-way doors 20, which are arranged circumferentially around the bait 40, i.e., evenly distributed around the bait 40, so as to provide multiple entry and exit paths for crustaceans such as shrimp and crabs and improve the success rate of trapping.

[0082] Furthermore, the side wall of the upper cage 131 is provided with multiple fishing channels 15 for attracting fish. The fishing channels 15 are connected to the cavity 11, and the multiple fishing channels 15 are arranged at intervals along the circumference of the bait 40. Preferably, the fishing channels 15 can correspond to the positions of the one-way door 20 so as to realize the multi-directional guidance of aquatic organisms into the cage.

[0083] In some embodiments, the aquatic product trapping device 100 includes a plurality of fishing elements 50, which are detachably embedded in the side wall of the upper cage 131. The fishing channel 15 is formed in the fishing element 50 and is funnel-shaped. The small end of the fishing channel 15 is located in the cavity 11 to prevent fish from escaping after entering.

[0084] In one embodiment, a rotating member 16 protrudes from the inner sidewall of the cage body 13, and a mating member 21 protrudes from the inner sidewall of the one-way door 20. One of the rotating member 16 and the mating member 21 is provided with a rotating shaft 211, and the other is provided with a shaft hole 161 that rotatably engages with the rotating shaft 211.

[0085] In this embodiment, to ensure that the one-way door 20 can be reliably rotated at the trapping opening 12, and to reduce the wall thickness of the cage body 10 to lower the overall weight, a rotating member 16 protrudes from the inner wall of the cage body 13, and a mating member 21 protrudes from the inner wall of the one-way door 20. One of the rotating member 16 and the mating member 21 is provided with a rotating shaft 211, and the other is provided with a shaft hole 161 that rotatably engages with the rotating shaft 211, so as to form a stable rotating pair connection relationship, allowing the one-way door 20 to flip and switch between a first position and a second position around the rotating shaft 211.

[0086] By concentrating the rotating structure on the local protruding part, a reliable rotating connection can be achieved without significantly thickening the wall of the entire cage body 13. This effectively reduces the overall weight and material cost while improving portability and practicality, provided that the structural strength requirements are met.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
