Description

Technical Field

[0001] The invention relates to the field of squid spawning attachments, and in particular to an artificial squid spawning attachment device. Background Art

[0002] Cuttlefish have a very narrow spawning habitat and require high levels of anchorage. In recent years, marine pollution, destruction of spawning grounds, and other factors have led to a year-on-year decline in cuttlefish production. To protect cuttlefish resources, stocking and artificial spawning anchorage have been widely used as supplementary methods to enhance the stocking process, achieving some success. Artificial spawning anchorage typically utilizes a combination of cages and ropes.

[0003] At present, although the squid spawning attachment that combines an artificial cage and an egg-laying rope can be used as a squid spawning attachment; however, since squid like to lay eggs on attachments close to the seabed (generally attached to egg-laying ropes within 60 cm from the seabed), bottom-sinking squid spawning attachments are generally used. Therefore, when collecting eggs, the squid spawning attachment needs to be lifted up by a rope. During this process, the squid eggs attached to the egg-laying rope will be impacted by seawater, causing the squid eggs on the egg-laying rope to fall off and be lost. Summary of the Invention

[0004] The purpose of the present invention is to provide a squid spawning attachment device that can adapt to the squid's habit of laying eggs on attachments close to the seabed and can effectively avoid the problem of squid eggs falling off and being lost due to the impact of seawater when collecting eggs.

[0005] The technical solution of the present invention is:

[0006] A squid spawning attachment device, comprising:

[0007] The attachment frame comprises a base and a top plate, with a plurality of egg-attaching ropes provided between the base and the top plate;

[0008] A plurality of protective plates hinged to the edges of the top plate, each provided with a clamping rod;

[0009] A clamping piece is provided on the top plate and corresponds to the clamping rods one by one, and is provided with a clamping interface with an opening facing upward;

[0010] The sliding assembly includes a lifting member that is slidably mounted on the top plate, a one-way pushing member that is rotatably mounted on the lifting member, and a limiting member located below the one-way pushing member;

[0011] A connecting rope, one end of which is connected to the lifting member and the other end of which is provided with a buoyancy member;

[0012] The attachment frame is lowered to the seabed using a connecting rope. During this process, the protective plates rotate upward under the influence of the water flow, causing the connecting rods to engage with the corresponding locking interfaces. Once the attachment frame is lowered to the seabed, the protective plates are secured in place by the connecting rods, leaving the gap between the base and top plates open. This allows cuttlefish to enter the attachment frame through the space between the base and top plates, lay their eggs on the attachment rope, and attach them to the attachment rope. Furthermore, since the attachment frame is lowered to the seabed, the attachment rope is located within 60 centimeters of the seabed, accommodating the cuttlefish's preference for laying eggs on attachments close to the seabed.

[0013] After the base is supported on the seabed, the connecting rope is released, the buoyancy member floats on the sea surface, and the lifting member moves downward under its own weight, causing the one-way pusher to move below the clamping member. Because the limiter is located below the one-way pusher, during the downward movement of the lifting member, when the one-way pusher abuts against the clamping rod, the one-way pusher can rotate upward about its axis, allowing the lifting member to continue to move downward. After the lifting member moves downward a set distance and the one-way pusher rotates upward about its axis a set angle, the one-way pusher will pass the clamping rod. Then, under the action of its own weight, the one-way pusher rotates downward and abuts against the limiter.

[0014] During retrieval, the attachment frame is lifted using the connecting rope. During this process, the lifting member first moves upward. During this upward movement, the one-way pusher pushes the connecting rod upward, separating the connecting rod from the locking interface. At this point, the protective plate rotates downward and abuts against the edge of the base. Because the buoyancy member floats on the sea surface, the attachment frame can be easily lifted using the connecting rope during retrieval. During this process, the lifting member first moves upward. Because the limiter is located below the one-way pusher and abuts against it (restraining its downward rotation), the one-way pusher pushes the connecting rod upward during this upward movement, separating the connecting rod from the locking interface. At this point, the protective plate rotates downward under its own weight and abuts against the edge of the base. This shields the space between the top plate and the base, protecting the egg attachment rope and the squid eggs attached to it within the space enclosed by the top plate, base, and the protective plates. In this way, when the connecting rope lifts the attachment frame, it can effectively prevent seawater from impacting the squid eggs, thereby effectively preventing the squid eggs from falling off and being lost due to the impact of seawater on the squid eggs.

[0015] Preferably, the edge of the base is provided with a plurality of shield support members extending outward from the base. When the engaging rods are separated from the engaging interfaces, the shields rotate downward and abut against the shield support members. At this point, the lower ends of the shields tilt outward from the base, and a gap is formed between the shields and the edge of the base. This allows water to enter through the gap between the shields and the edge of the base during the lowering of the attachment frame to the seabed using the connecting rope, thereby ensuring that the shields rotate upward under the impact of the water flow until the engaging rods engage the corresponding engaging interfaces.

[0016] Preferably, the protective plate is provided with a protective plate support member, and the protective plate support member and the clamping rod are located on either side of the protective plate. When the clamping rod is separated from the clamping interface, the protective plate rotates downward and abuts against the edge of the base through the protective plate support member. At this time, the lower end of the protective plate is tilted toward the outside of the base, and a gap is formed between the protective plate and the edge of the base. In this way, when the attachment frame is lowered to the seabed using the connecting rope, water can enter through the gap between the protective plate and the edge of the base, thereby ensuring that the protective plate rotates upward under the impact of the water flow until the clamping rod is locked into the corresponding clamping interface.

[0017] Preferably, a vertical guide rod is provided in the middle of the upper surface of the top plate, an upper stopper is provided at the top of the vertical guide rod, and the lifting member is lifted and slid along the vertical guide rod, with the lifting member being located between the top plate and the upper stopper. In this way, the lifting member is ensured to be able to stably lift and slide on the vertical guide rod, and the high point and low point positions of the lifting member are determined.

[0018] Preferably, when the connecting rod is engaged with the corresponding connecting interface, the end of the protective plate away from the top plate tilts upward. Thus, when the connecting rod is engaged with the corresponding connecting interface, the space between the base and the top plate is opened, allowing the squid to lay eggs through the space between the base and the top plate into the attachment frame, lay eggs on the egg-attaching rope, and attach the squid eggs to the egg-attaching rope.

[0019] Preferably, when the connecting rod is engaged with the corresponding connecting interface, the end of the protective plate away from the top plate tilts downward. Thus, when the connecting rod is engaged with the corresponding connecting interface, the space between the base and the top plate is opened, allowing the squid to lay eggs through the space between the base and the top plate into the attachment frame, lay eggs on the egg-attaching rope, and attach the squid eggs to the egg-attaching rope.

[0020] Preferably, the clip includes a C-shaped clip with an upward opening, the inner cavity of the C-shaped clip forming the clip interface, and guide members extending upward are provided at both ends of the C-shaped clip. A guide opening is formed between the guide members at both ends of the C-shaped clip, and the opening of the guide opening gradually increases from bottom to top. In this way, when the attachment frame is lowered to the seabed using a connecting rope, and the protective plate rotates upward under the impact of the water flow, the clip rod can be guided by the guide opening between the guide members at both ends of the C-shaped clip, ensuring that the clip rod is smoothly inserted into the corresponding clip interface. During recovery, when the attachment frame is lifted by the connecting rope, the one-way pusher can smoothly push the clip rod to rotate upward as the lifting member first moves upward, ensuring that the clip rod and the clip interface are smoothly separated.

[0021] Preferably, the egg-laying rope is a nylon rope. Using a nylon rope as the egg-laying rope can increase the number of eggs laid by the squid on the egg-laying rope.

[0022] Preferably, the attachment frame also includes a central rod connecting the base and the top plate. This allows the central rod to support the base and the top plate, creating sufficient space between them for the squid to enter and lay eggs. Furthermore, it provides more space for the egg-laying ropes, facilitating the placement of more egg-laying ropes.

[0023] The beneficial effects of the present invention are: it can adapt to the habit of squids to lay eggs on attachments close to the seabed, and can effectively avoid the problem of squid eggs falling off and being lost due to the impact of seawater on the squid eggs when collecting eggs.

[0038] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0039] Specific embodiment 1, as Figure 1 、 Figure 2 、 Figure 4 As shown, a squid spawning attachment device includes: an attachment frame 1, a plurality of protective plates 3, a plurality of clamping parts 5, a sliding assembly 6 and a connecting rope 7.

[0040] The attachment frame 1 includes a base 1.1 and a top plate 1.2, with a space formed between the base 1.1 and the top plate 1.2 for installing the egg-attaching rope 2. A plurality of egg-attaching ropes 2 are arranged between the base 1.1 and the top plate 1.2. The egg-attaching ropes 2 extend vertically.

[0041] Each protective plate 3 is distributed around the top plate 1.2. One end of the protective plate 3 is hinged to the edge of the top plate 1.2. A clamping rod 4 is provided on the protective plate 3, and the clamping rod 4 is close to one end of the protective plate 3.

[0042] The clamping member 5 corresponds to the clamping rod 4 in a one-to-one manner. The clamping member 5 is arranged on the top plate 1.2. The clamping member 5 is provided with a clamping interface 5.1 with an upward opening. The clamping interface 5.1 is used to clamp the clamping rod 4.

[0043] The sliding assembly 6 comprises a lifting member 6.1 slidably arranged on the top plate 1.2, a one-way pushing member 6.2 rotatably arranged on the lifting member 6.1 and a limiting member 6.3 located below the one-way pushing member 6.2.

[0044] One end of the connecting rope 7 is connected to the lifting member 6.1, and the other end of the connecting rope 7 is provided with a buoyancy member 8.

[0045] The attachment frame 1 is lowered to the seabed using the connecting rope 7. During this process, the protective plate 3 rotates upward under the action of the water flow, and the connecting rod 4 is locked into the corresponding connecting interface 5.1. Figure 1As shown in the figure, after the attachment frame 1 is lowered to the seabed, the protective plate 3 is secured to the corresponding latching interface 5.1 via the latching rod 4, leaving the space between the base 1.1 and the top plate 1.2 open. This allows squid to enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 to lay eggs, depositing them on the egg-laying rope 2 and attaching them to it. Furthermore, since the attachment frame 1 is lowered to the seabed, the egg-laying rope 2 is located within 60 centimeters of the seabed, thus accommodating the squid's preference for laying eggs on attachments close to the seabed.

[0046] like Figure 1 As shown, after the base 1.1 is supported on the seabed, the connecting rope 7 is released, the buoyancy member 8 floats on the sea surface, and the lifting member 6.1 moves downward under its own weight, causing the one-way pusher 6.2 to move below the clamping member 5. Because the limiting member 6.3 is located below the one-way pusher 6.2, during the downward movement of the lifting member 6.1, when the one-way pusher 6.2 abuts against the clamping rod 4, the one-way pusher 6.2 can rotate upward about its axis, thereby allowing the lifting member 6.1 to continue to move downward. After the lifting member 6.1 moves downward a set distance and the one-way pusher 6.2 rotates upward about its axis a set angle, the one-way pusher 6.2 will pass over the clamping rod 4, and then the one-way pusher 6.2 rotates downward under its own weight and abuts against the limiting member 6.3.

[0047] During recycling (recycling refers to collecting squid eggs), the attachment frame 1 is lifted by the connecting rope 7. During this process, the lifting member 6.1 moves upward first. During the upward movement of the lifting member 6.1, the one-way pushing member 6.2 pushes the clamping rod 4 to rotate upward, so that the clamping rod 4 is separated from the clamping interface 5.1. At this time, the protective plate 3 rotates downward and abuts against the edge of the base 1.1. Figure 4 As shown, because the buoyancy member 8 floats on the sea surface, the attachment frame 1 can be easily lifted via the connecting rope 7 during recovery. As the connecting rope 7 lifts the attachment frame 1, the lifting member 6.1 first moves upward. During this upward movement, the limiting member 6.3 is located below the one-way pusher 6.2, and the one-way pusher 6.2 abuts against the limiting member 6.3 (restricting the one-way pusher 6.2 from rotating downward). As the lifting member 6.1 moves upward, the one-way pusher 6.2 pushes the connecting rod 4 upward, separating the connecting rod 4 from the connecting interface 5.1. At this point, the protective plates 3 rotate downward under their own weight and abut against the edge of the base 1.1. The protective plates 3 thus block the space between the top plate 1.2 and the base 1.1, protecting the egg-attaching rope 2 and the squid eggs on it within the space enclosed by the top plate 1.2, the base 1.1, and the protective plates 3. In this way, when the connecting rope 7 lifts the attachment frame 1, the squid eggs can be effectively prevented from being impacted by seawater and causing the squid eggs to fall off and be lost. After the attachment frame 1 is lifted by the connecting rope 7, the squid eggs can be collected.

[0048] Specific embodiment 2, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a squid spawning attachment device includes: an attachment frame 1, a plurality of protective plates 3, a plurality of clamping parts 5, a sliding assembly 6 and a connecting rope 7.

[0049] The attachment frame 1 comprises a base 1.1 and a top plate 1.2. Space is formed between the base 1.1 and the top plate 1.2 for mounting the egg-attaching cords 2. Several egg-attaching cords 2 are positioned between the base 1.1 and the top plate 1.2. The egg-attaching cords 2 extend vertically. In this embodiment, the attachment frame 1 also includes a central rod 1.3 connecting the base 1.1 and the top plate 1.2. The central rod 1.3 is located midway between the base 1.1 and the top plate 1.2.

[0050] In one embodiment of this invention, the attachment frame 1 comprises a base 1.1, a top plate 1.2, and a central rod 1.3 connecting the base 1.1 and the top plate 1.2. This allows the central rod 1.3 to support the base 1.1 and the top plate 1.2, creating ample space between the base 1.1 and the top plate 1.2 for the squid to enter and lay eggs. Furthermore, this provides more space for the egg-laying ropes 2, facilitating the placement of more egg-laying ropes 2.

[0051] In another implementation of this embodiment, the attachment frame 1 includes a base 1.1, a top plate 1.2 and a plurality of connecting rods connecting the base 1.1 and the top plate 1.2.

[0052] Each protective plate 3 is distributed around the top plate 1.2. One end of the protective plate 3 is hinged to the edge of the top plate 1.2. A connecting rod 4 is provided on each protective plate 3, located near one end of the protective plate 3. In this embodiment, each protective plate 3 is provided with a connecting rod 4, and the connecting rod 4 is perpendicular to the protective plate 3. Of course, it should be noted that the connecting rod 4 and the protective plate 3 do not need to be perpendicular, and the connecting rod 4 and the protective plate 3 can be arranged at an angle greater than 90 degrees or less than 90 degrees.

[0053] Base 1.1 is square, circular, regular polygonal, or other irregularly shaped. Top plate 1.2 is square, circular, regular polygonal, or other irregularly shaped. In this embodiment, base 1.1 is square, and corresponding top plate 1.2 is also square. There are four protective plates 3, one for each side of top plate 1.2, and one end of each protective plate 3 is hinged to the side of top plate 1.2.

[0054] The clamping member 5 corresponds to the clamping rod 4 in a one-to-one manner. In this embodiment, the clamping member 5 is an elastic clamping member. The clamping member 5 is arranged on the top plate 1.2. The clamping member 5 is provided with a clamping interface 5.1 with an upward opening. The clamping interface 5.1 is used to clamp the clamping rod 4.

[0055] The sliding assembly 6 comprises a lifting member 6.1 that is slidably mounted on the top plate 1.2, a one-way pusher 6.2 that is rotatably mounted on the lifting member 6.1, and a stopper 6.3 located below the one-way pusher 6.2. The stopper 6.3 is fixed to the lifting member 6.1, and the one-way pusher 6.2 rotates about its axis and abuts against the stopper 6.3.

[0056] In one implementation of this embodiment, Figure 1 As shown, a vertical guide rod 9 is provided in the middle of the upper surface of the top plate 1.2, and an upper stop block 9.1 is provided on the top of the vertical guide rod 9. The lifting member 6.1 is a lifting sleeve. The lifting member 6.1 rises and slides along the vertical guide rod 9, and the lifting member 6.1 is located between the top plate 1.2 and the upper stop block 9.1. In this way, it is ensured that the lifting member 6.1 can stably rise and slide on the vertical guide rod 9, and the high point position and the low point position of the lifting member 6.1 are determined (in this embodiment, the high point position of the lifting member 6.1 means that the lifting member 6.1 is against the upper stop block 9.1; the low point position of the lifting member 6.1 means that the lifting member 6.1 is against the upper surface of the top plate 1.2). The lifting sleeve and the vertical guide rod 9 cannot rotate relative to each other. For example, the vertical guide rod 9 is provided with an axial projection extending axially along the vertical guide rod 9, and the inner wall of the lifting sleeve is provided with an axial through-groove that cooperates with the axial projection. The axial projection extends into the axial through-groove, so that the lifting sleeve and the vertical guide rod 9 cannot rotate relative to each other, but the lifting member 6.1 can rise and fall and slide along the vertical guide rod 9. For another example, the vertical guide rod 9 may have a square, polygonal, or other special-shaped cross-section, and the cross-section of the inner hole of the lifting sleeve matches the cross-section of the vertical guide rod 9, so that the lifting sleeve and the vertical guide rod 9 cannot rotate relative to each other, but the lifting member 6.1 can rise and fall and slide along the vertical guide rod 9.

[0057] In another embodiment of this embodiment, a vertically extending guide hole is provided in the middle of the upper surface of the top plate 1.2, and the lifting member 6.1 is a lifting rod, which rises and falls and slides along the guide hole (not shown in the figure of this embodiment). A lower stopper is provided at the lower end of the lifting rod, and the lower stopper is located below the top plate 1.2. The one-way pusher 6.2 and the limiter 6.3 are located above the top plate 1.2. In this way, it is ensured that the lifting member 6.1 can stably rise and fall and slide in the guide hole, and the high point position and the low point position of the lifting member 6.1 are determined (in this embodiment, the high point position of the lifting member 6.1 refers to the lower stopper abutting against the lower surface of the top plate 1.2; the low point position of the lifting member 6.1 refers to the limiter 6.3 abutting against the upper surface of the top plate 1.2). The lifting member 6.1 and the guide hole cannot rotate relative to each other. For example, the lifting rod may be provided with an axial projection extending along the axial direction of the lifting rod, and the inner wall of the guide hole may be provided with an axial groove that cooperates with the axial projection. The axial projection extends into the axial groove, so that the lifting member 6.1 and the guide hole cannot rotate relative to each other, but the lifting member 6.1 can be lifted and slid along the guide hole. For another example, the lifting rod may have a square, polygonal, or other shaped cross-section, and the cross-section of the guide hole may match the cross-section of the lifting rod, so that the lifting member 6.1 and the guide hole cannot rotate relative to each other, but the lifting member 6.1 can be lifted and slid along the guide hole.

[0058] One end of the connecting rope 7 is connected to the lifting member 6.1, and the other end of the connecting rope 7 is provided with a buoyancy member 8. The buoyancy member 8 is a floating block or a floating ball.

[0059] The specific use process of the squid spawning attachment device of this embodiment is as follows:

[0060] When the squid spawning attachment device is lowered to the seabed, the attachment frame 1 is lowered to the seabed using the connecting rope 7. During this process, the lifting member 6.1 first rises to the highest point, and then the connecting rope 7 lifts the attachment frame 1 through the lifting member 6.1 and lowers the attachment frame 1 to the seabed. During the process of lowering the attachment frame 1 to the seabed, the protective plate 3 rotates upward under the action of the water flow, and the clamping rod 4 is clamped into the corresponding clamping interface 5.1. Figure 1 As shown. After the attachment frame 1 is lowered to the seabed, the protective plate 3 is secured to the corresponding latching interface 5.1 via the latching rods 4, leaving the space between the base 1.1 and the top plate 1.2 open. This allows the squid to enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 to lay eggs, depositing them on the egg-laying rope 2. Furthermore, since the attachment frame 1 is lowered to the seabed, the egg-laying rope 2 is located within 60 centimeters of the seabed, accommodating the squid's preference for laying eggs on attachments close to the seabed. Once the latching rods 4 are engaged in the corresponding latching interfaces 5.1, the latching rods 4 are distributed around the lifting rod, extending diagonally upward from the edge of the top plate 1.2 toward the center.

[0061] like Figure 1As shown, after the base 1.1 is supported on the seabed, the connecting rope 7 is released, the buoyancy member 8 floats on the sea surface, and the lifting member 6.1 moves downward under its own weight, causing the one-way pusher 6.2 to move below the clamping member 5 until the lifting member 6.1 moves down to the lowest point. Because the limiter 6.3 is located below the one-way pusher 6.2, during the downward movement of the lifting member 6.1, when the one-way pusher 6.2 abuts against the clamping rod 4, the one-way pusher 6.2 can rotate upward about its axis, thereby allowing the lifting member 6.1 to continue to move downward. After the lifting member 6.1 moves downward a set distance and the one-way pusher 6.2 rotates upward about its axis a set angle, the one-way pusher 6.2 will pass over the clamping rod 4, and then the one-way pusher 6.2 rotates downward under its own weight and abuts against the limiter 6.3.

[0062] During recycling (recycling refers to collecting squid eggs), the attachment frame 1 is lifted by the connecting rope 7. During this process, the lifting member 6.1 first moves upward to the highest point. During the upward movement of the lifting member 6.1, the one-way pushing member 6.2 pushes the clamping rod 4 to rotate upward, so that the clamping rod 4 is separated from the clamping interface 5.1. At this time, the protective plate 3 rotates downward under the action of its own weight and abuts against the edge of the base 1.1. Figure 4 As shown, because the buoyancy member 8 floats on the sea surface, the attachment frame 1 can be easily lifted via the connecting rope 7 during recovery. As the connecting rope 7 lifts the attachment frame 1, the lifting member 6.1 first moves upward. During this upward movement, the limiting member 6.3 is located below the one-way pusher 6.2, and the one-way pusher 6.2 abuts against the limiting member 6.3 (restricting the one-way pusher 6.2 from rotating downward). As the lifting member 6.1 moves upward, the one-way pusher 6.2 pushes the connecting rod 4 upward, separating the connecting rod 4 from the connecting interface 5.1. At this point, the protective plates 3 rotate downward under their own weight and abut against the edge of the base 1.1. The protective plates 3 thus block the space between the top plate 1.2 and the base 1.1, protecting the egg-attaching rope 2 and the squid eggs on it within the space enclosed by the top plate 1.2, the base 1.1, and the protective plates 3. In this way, when the connecting rope 7 lifts the attachment frame 1, the squid eggs can be effectively prevented from being impacted by seawater and causing the squid eggs to fall off and be lost. After the attachment frame 1 is lifted by the connecting rope 7, the squid eggs can be collected.

[0063] In this embodiment, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the state of the protective plate 3 can be the following:

[0064] In one way, as Figure 1As shown, when the connecting rod 4 is engaged with the corresponding connecting interface 5.1, the end of the protective plate 3 away from the top plate 1.2 tilts upward. Thus, when the connecting rod 4 is engaged with the corresponding connecting interface 5.1, the space between the base 1.1 and the top plate 1.2 is opened, allowing the squid to lay eggs through the space between the base 1.1 and the top plate 1.2 into the attachment frame 1, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2.

[0065] In another embodiment, when the connecting rod 4 is engaged with the corresponding connecting interface 5.1, the end of the protective plate 3 away from the top plate 1.2 tilts downward. Thus, when the connecting rod 4 is engaged with the corresponding connecting interface 5.1, the space between the base 1.1 and the top plate 1.2 is opened, allowing the squid to lay eggs through the space between the base 1.1 and the top plate 1.2 into the attachment frame 1, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2.

[0066] In the third embodiment, when the connecting rod 4 is inserted into the corresponding connecting interface 5.1, the protective plate 3 is parallel to the top plate 1.2. Thus, when the connecting rod 4 is inserted into the corresponding connecting interface 5.1, the space between the base 1.1 and the top plate 1.2 is opened, allowing the squid to lay eggs through the space between the base 1.1 and the top plate 1.2 into the attachment frame 1, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2.

[0067] In this embodiment, there are multiple one-way pushers 6.2. Each one-way pusher 6.2 corresponds to a corresponding connecting rod 4, and a stopper 6.3 is provided below each one-way pusher 6.2. The one-way pusher 6.2 is a push plate or a push rod. Thus, during recovery, when the attachment frame 1 is lifted via the connecting rope 7, the lifting member 6.1 first moves upward to the highest point. As the lifting member 6.1 moves upward, the one-way pusher 6.2 pushes the corresponding connecting rod 4 to rotate upward, separating the connecting rod 4 from the card interface 5.1.

[0068] Of course, it should be noted that one one-way pushing member 6.2 can also correspond to two or more connecting rods 4. For example, a cross bar is provided at the end of the one-way pushing member 6.2. During recovery, when the attachment frame 1 is lifted by the connecting rope 7, the lifting member 6.1 first moves upward to the highest point. During the upward movement of the lifting member 6.1, the cross bar of the one-way pushing member 6.2 pushes the corresponding two or more connecting rods 4 to rotate upward, so that the connecting rod 4 is separated from the card interface 5.1.

[0069] Furthermore, the egg-laying rope 2 is a nylon rope. Using a nylon rope as the egg-laying rope 2 can increase the number of eggs laid by the squid on the egg-laying rope 2. Of course, it should be noted that the egg-laying rope 2 can also be other ropes. C-shaped buckle 5.2

[0070] Further, such as Figure 1 、 Figure 3As shown, the clip 5 includes a C-shaped clip 5.2 with an upward opening. The C-shaped clip 5.2 is an elastic clip. The inner cavity of the C-shaped clip 5.2 forms the aforementioned clip interface 5.1. Both ends of the C-shaped clip 5.2 are provided with guide members 5.3 extending upward. A guide opening 5.4 is formed between the guide members 5.3 at both ends of the C-shaped clip 5.2, and the opening of the guide opening 5.4 gradually increases from bottom to top. In this way, when the attachment frame 1 is lowered to the seabed using the connecting rope 7, the protective plate 3 rotates upward under the impact of the water flow. The clip rod 4 can be guided by the guide opening 5.4 between the guide members 5.3 at both ends of the C-shaped clip 5.2, ensuring that the clip rod 4 is smoothly inserted into the corresponding clip interface 5.1. During recovery, when the attachment frame 1 is lifted using the connecting rope 7, the one-way pusher 6.2 can smoothly push the clip rod 4 upward as the lifting member 6.1 moves upward, ensuring that the clip rod 4 and the clip interface 5.1 are smoothly separated.

[0071] Specific embodiment 3: The rest of the structure of this embodiment refers to specific embodiment 1, except that:

[0072] In one implementation of this embodiment, Figure 4 As shown, the edge of the base 1.1 is provided with a number of guard plate supports 1.4 extending toward the outside of the base 1.1. The guard plate supports 1.4 are rod-shaped or block-shaped. When the clamping rod 4 is separated from the clamping interface 5.1, the protective plate 3 rotates downward under its own weight and rests on the guard plate supports 1.4. At this time, the lower end of the protective plate 3 tilts toward the outside of the base 1.1, and there is a gap between the protective plate 3 and the edge of the base 1.1. In this way, when the attachment frame 1 is lowered to the seabed using the connecting rope 7, water can enter through the gap between the protective plate 3 and the edge of the base 1.1, thereby ensuring that the protective plate 3 rotates upward under the impact of the water flow until the clamping rod 4 is clamped into the corresponding clamping interface 5.1.

[0073] In another implementation of this embodiment, a guard plate support 1.4 is provided on the guard plate 3, and the guard plate support 1.4 and the clamping rod 4 are located on both sides of the guard plate 3. The guard plate support 1.4 is rod-shaped or block-shaped. When the clamping rod 4 is separated from the clamping interface 5.1, the guard plate 3 rotates downward under the action of its own weight and rests on the edge of the base 1.1 through the guard plate support 1.4. At this time, the lower end of the guard plate 3 tilts toward the outside of the base 1.1, and there is a gap between the guard plate 3 and the edge of the base 1.1. In this way, when the attachment frame 1 is lowered to the seabed using the connecting rope 7, water can enter through the gap between the edge of the guard plate 3 and the base 1.1, thereby ensuring that the guard plate 3 rotates upward under the impact of the water flow until the clamping rod 4 is clamped into the corresponding clamping interface 5.1.

[0074] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still fall within the scope of protection of the technical solution of the present invention.
