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] The spawning habitat of squid is very narrow, and the requirements for attachments for squid spawning are relatively high. In recent years, due to various reasons such as marine environmental pollution and destruction of spawning sites, the production of squid has been declining year by year. In order to protect squid resources, the release of squid and the placement of artificial spawning attachments are widely used as supplementary means in the process of squid resource proliferation, and have achieved certain results; among them, artificial squid spawning attachments are generally a combination of artificial cages and egg-attaching ropes.

[0003] At present, although the squid spawning attachment combined with the artificial net cage and the 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 the egg-laying rope 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 sea water, 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 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 seawater impact during egg collection.

[0005] The technical solution of the present invention is: A squid spawning attachment device, comprising: The attachment frame comprises a base and a top plate, and a plurality of egg-attaching ropes are arranged between the base and the top plate; A plurality of protective plates hinged to the edge of the top plate, each of which is provided with a clamping rod; A clamping piece arranged on the top plate and corresponding to the clamping rods one by one, and provided with a clamping interface with an opening facing upward; The sliding assembly comprises a lifting member that is slidably arranged on the top plate, a one-way pushing member that is rotatably arranged on the lifting member, and a limiting member located below the one-way pushing member; 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; The attachment frame is lowered to the seabed using a connecting rope. During this process, the protective plate rotates upward under the action of the water flow, and the clamping rod is clamped into the corresponding clamping interface. In this way, after the attachment frame is lowered to the seabed, the protective plate is fixed in the corresponding clamping interface through the clamping rod, so that the base and the top plate are in an open state, so that when squid lay eggs, they can enter the attachment frame through the space between the base and the top plate, lay eggs on the egg-attaching rope, and attach the squid eggs to the egg-attaching rope. At the same time, because the attachment frame is lowered to the seabed, the egg-attaching rope is located within 60 cm from the seabed, so it can adapt to the squid's habit of laying eggs on attachments close to the seabed.

[0006] When the base is supported on the seabed, the connecting rope is released, the buoyancy member floats on the sea surface, the lifting member moves downward under the action of its own weight and causes the one-way push member to move below the clamping member. Since 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 around the axis, so that the lifting member can continue to move downward. After the lifting member moves downward for a set distance and the one-way pusher rotates upward around the axis for a set angle, the one-way pusher will pass over the clamping rod, and then the one-way pusher rotates downward under the action of its own weight and abuts against the limiter.

[0007] During the recovery, the attachment frame is lifted by the connecting rope. During the process, the lifting member moves upward first. During the upward movement of the lifting member, the one-way pusher pushes the clamping rod to rotate upward, so that the clamping rod is separated from the clamping interface. At this time, the protective plate rotates downward and abuts against the edge of the base. Since the buoyancy member floats on the sea surface, the attachment frame can be easily lifted by the connecting rope during the recovery. During the process of the attachment frame being lifted by the connecting rope, the lifting member moves upward first. During the upward movement of the lifting member, the limiter is located below the one-way pusher and the one-way pusher abuts against the limiter (limiting the one-way pusher from rotating downward). Therefore, during the upward movement of the lifting member, the one-way pusher will push the clamping rod to rotate upward, so that the clamping rod is separated from the clamping interface. At this time, the protective plate will rotate downward and abut against the edge of the base under the action of its own weight, thereby shielding the space between the top plate and the base through each protective plate, and protecting the egg-attaching rope and the squid eggs on the egg-attaching rope in the space enclosed between the top plate, the base and each protective plate. 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.

[0008] Preferably, the edge of the base is provided with a plurality of guard plate support members extending toward the outside of the base. When the clamping rod is separated from the clamping interface, the guard plate rotates downward and abuts against the guard plate support member. At this time, the lower end of the guard plate is tilted toward the outside of the base, and there is a gap between the guard plate and the edge of the base. In this way, when the attachment frame is lowered to the seabed using a connecting rope, water can enter through the gap between the guard plate and the edge of the base, thereby ensuring that the guard plate rotates upward under the impact of the water flow until the clamping rod is clamped into the corresponding clamping interface.

[0009] Preferably, a guard plate support is provided on the guard plate, and the guard plate support and the clamping rod are located on both sides of the guard plate. When the clamping rod is separated from the clamping interface, the guard plate rotates downward and abuts against the edge of the base through the guard plate support. At this time, the lower end of the guard plate is inclined toward the outside of the base, and there is a gap between the guard plate and the edge of the base. In this way, when the attachment frame is lowered to the seabed using a connecting rope, water can enter through the gap between the guard plate and the edge of the base, thereby ensuring that the guard plate rotates upward under the impact of the water flow until the clamping rod is clamped into the corresponding clamping interface.

[0010] 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, the lifting member is lifted and slid along the vertical guide rod, and the lifting member is located between the top plate and the upper stopper. In this way, it is ensured that the lifting member can stably lift and slide on the vertical guide rod, and the high point position and the low point position of the lifting member are determined.

[0011] Preferably, when the connecting rod is inserted into the corresponding connecting interface, the end of the protective plate away from the top plate is tilted upward. In this way, when the connecting rod is inserted into the corresponding connecting interface, the base and the top plate will be in an open state, so that the squid can enter the attachment frame through the space between the base and the top plate when laying eggs, lay eggs on the egg-attaching rope, and attach the squid eggs to the egg-attaching rope.

[0012] Preferably, when the connecting rod is inserted into the corresponding connecting interface, the end of the protective plate away from the top plate is tilted downward. In this way, when the connecting rod is inserted into the corresponding connecting interface, the base and the top plate will be in an open state, so that the squid can enter the attachment frame through the space between the base and the top plate when laying eggs, lay eggs on the egg-attaching rope, and attach the squid eggs to the egg-attaching rope.

[0013] Preferably, the clamping member includes a C-shaped clamp with an upward opening, the inner cavity of the C-shaped clamp forms the clamping interface, both ends of the C-shaped clamp are provided with guide members extending upward, a guide opening is formed between the guide members at both ends of the C-shaped clamp, 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 the connecting rope, and the protective plate rotates upward under the impact of the water flow, the clamping rod can be guided by the guide opening between the guide members at both ends of the C-shaped clamp, so as to ensure that the clamping rod is smoothly inserted into the corresponding clamping interface. During recovery, when the attachment frame is lifted by the connecting rope, the one-way pusher can smoothly push the clamping rod to rotate upward during the upward movement of the lifting member, so as to ensure the smooth separation of the clamping rod and the clamping interface.

[0014] 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.

[0015] Preferably, the attachment frame further comprises a central rod connecting the base and the top plate. Thus, on the one hand, the base and the top plate can be supported by the central rod, and sufficient space can be formed between the base and the top plate for the squid to enter and lay eggs; on the other hand, more space can be provided for the egg-attaching ropes, which is conducive to arranging more egg-attaching ropes.

[0016] 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.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: 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 protection plates 3, a plurality of clamping parts 5, a sliding assembly 6 and a connecting rope 7.

[0023] The attachment frame 1 comprises a base 1.1 and a top plate 1.2, and a space for installing an egg-attaching rope 2 is formed between the base 1.1 and the top plate 1.2. 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 are distributed extending up and down.

[0024] 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.

[0025] The clamping member 5 corresponds to the clamping rod 4 one by one. 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 opening facing upward. The clamping interface 5.1 is used for clamping the clamping rod 4.

[0026] The sliding assembly 6 comprises a lifting member 6.1 which is slidably disposed on the top plate 1.2, a one-way pushing member 6.2 which is rotatably disposed on the lifting member 6.1, and a limiting member 6.3 located below the one-way pushing member 6.2.

[0027] 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.

[0028] The attachment frame 1 is lowered to the seabed using the connecting rope 7. During this process, the protection 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 1As shown. In this way, after the attachment frame 1 is lowered to the seabed, the protective plate 3 is fixed in the corresponding card interface 5.1 through the card connecting rod 4, so that the base 1.1 and the top plate 1.2 are in an open state, so that the squid can enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 when laying eggs, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2. At the same time, because the attachment frame 1 is lowered to the seabed, the egg-attaching rope 2 is located within 60 cm from the seabed, so it can adapt to the habit of squid to lay eggs on attachments close to the seabed.

[0029] 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 the action of its own weight and causes the one-way push member 6.2 to move below the clamping member 5. Since the limiting member 6.3 is located below the one-way push member 6.2, during the downward movement of the lifting member 6.1, when the one-way push member 6.2 abuts against the top of the clamping rod 4, the one-way push member 6.2 can rotate upward around the axis, so that the lifting member 6.1 can continue to move downward. After the lifting member 6.1 moves downward by a set distance and the one-way push member 6.2 rotates upward around the axis by a set angle, the one-way push member 6.2 will pass over the clamping rod 4, and then the one-way push member 6.2 rotates downward under the action of its own weight and abuts against the limiting member 6.3.

[0030] When recycling (recycling means 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. Since the buoyancy member 8 floats on the sea surface, the attachment frame 1 can be conveniently lifted by the connecting rope 7 during recovery. In the process of the connecting rope 7 lifting the attachment frame 1, the lifting member 6.1 moves upward first, and in the process of the lifting member 6.1 moving upward, since the limiting member 6.3 is located below the one-way push member 6.2, and the one-way push member 6.2 abuts against the limiting member 6.3 (limiting the one-way push member 6.2 from rotating downward), the one-way push member 6.2 will push the clamping rod 4 to rotate upward during the lifting member 6.1 moving upward, so that the clamping rod 4 is separated from the clamping interface 5.1. At this time, the protective plate 3 will rotate downward under the action of its own weight and abut against the edge of the base 1.1, so that the space between the top plate 1.2 and the base 1.1 is blocked by each protective plate 3, and the egg-attaching rope 2 and the squid eggs on the egg-attaching rope 2 are protected in the space enclosed by the top plate 1.2, the base 1.1 and each protective plate 3. In this way, when the attachment frame 1 is lifted by the connecting rope 7, the problem of the squid eggs falling off and being lost due to the impact of seawater can be effectively avoided. After the attachment frame 1 is lifted by the connecting rope 7, the collection of the squid eggs can be realized.

[0031] 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 protection plates 3, a plurality of clamping parts 5, a sliding assembly 6 and a connecting rope 7.

[0032] The attachment frame 1 includes a base 1.1 and a top plate 1.2, and a space for installing an egg-attaching rope 2 is formed between the base 1.1 and the top plate 1.2. 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 are distributed extending up and down. In this embodiment, the attachment frame 1 also includes a center rod 1.3 connecting the base 1.1 and the top plate 1.2, and the center rod 1.3 is located in the middle of the base 1.1 and the top plate 1.2.

[0033] In one implementation of this embodiment, the attachment frame 1 is composed of a base 1.1, a top plate 1.2, and a center rod 1.3 connecting the base 1.1 and the top plate 1.2. In this way, on the one hand, the center rod 1.3 can support the base 1.1 and the top plate 1.2, forming a sufficient space between the base 1.1 and the top plate 1.2 for the squid to enter and lay eggs; on the other hand, it can provide more space for the egg-attaching rope 2, which is conducive to arranging more egg-attaching ropes 2.

[0034] 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.

[0035] 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. In this embodiment, each protective plate 3 is provided with a clamping rod 4, and the clamping rod 4 is perpendicular to the protective plate 3. Of course, it should be noted that the clamping rod 4 and the protective plate 3 may not be perpendicular, and the clamping rod 4 and the protective plate 3 are distributed at an angle greater than 90 degrees or less than 90 degrees.

[0036] The base 1.1 is a square, round, regular polygon or other special-shaped structure. The top plate 1.2 is a square, round, regular polygon or other special-shaped structure. In this embodiment, the base 1.1 is a square structure, and the corresponding top plate 1.2 is also a square structure. There are four protective plates 3, and each side of the top plate 1.2 corresponds to a protective plate 3, and one end of the protective plate 3 is hinged to the side of the top plate 1.2.

[0037] The clamping member 5 corresponds to the clamping rod 4 one by one. 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 opening facing upward. The clamping interface 5.1 is used to clamp the clamping rod 4.

[0038] The sliding assembly 6 comprises a lifting member 6.1 which is slidably mounted on the top plate 1.2, a one-way push member 6.2 which is rotatably mounted on the lifting member 6.1, and a stop member 6.3 which is located below the one-way push member 6.2. The stop member 6.3 is fixedly mounted on the lifting member 6.1, and the one-way push member 6.2 rotates around the axis and abuts against the stop member 6.3.

[0039] 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 stopper 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 is lifted and slid along the vertical guide rod 9, and the lifting member 6.1 is located between the top plate 1.2 and the upper stopper 9.1. In this way, it is ensured that the lifting member 6.1 can stably lift 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 stopper 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 along the axial direction of the vertical guide rod 9, and the inner wall of the lifting sleeve is provided with an axial through groove matched with the axial projection, and 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 slide and rise along the vertical guide rod 9. For another example, the cross section of the vertical guide rod 9 is a square, polygonal or special-shaped structure, 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 slide and rise along the vertical guide rod 9.

[0040] In another implementation 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 is lifted and slid along the guide hole (not shown in the figure of this implementation). A lower block is provided at the lower end of the lifting rod, and the lower block is located below the top plate 1.2. The one-way push member 6.2 and the limit member 6.3 are located above the top plate 1.2. In this way, it is ensured that the lifting member 6.1 can stably lift 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 implementation, the high point position of the lifting member 6.1 refers to that the lower block is against the lower surface of the top plate 1.2; the low point position of the lifting member 6.1 refers to that the limit member 6.3 is 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 is provided with an axial projection extending along the axial direction of the lifting rod, and the inner wall of the guide hole is provided with an axial through groove matched with the axial projection, and the axial projection extends into the axial through 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 cross section of the lifting rod is square, polygonal or special-shaped, and the cross section of the guide hole matches 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.

[0041] 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.

[0042] The specific use process of the squid spawning attachment device of this embodiment is as follows: 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, as shown in FIG. Figure 1 As shown. In this way, after the attachment frame 1 is lowered to the seabed, the protective plate 3 is fixed in the corresponding card interface 5.1 through the card rod 4, so that the base 1.1 and the top plate 1.2 will be in an open state, so that the squid can enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 when laying eggs, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2. At the same time, because the attachment frame 1 is lowered to the seabed, the egg-attaching rope 2 is located within 60 cm from the seabed, so it can adapt to the squid's habit of laying eggs on attachments close to the seabed. When the card rod 4 is inserted into the corresponding card interface 5.1, each card rod 4 is distributed around the lifting rod, and the card rod 4 extends obliquely upward from the edge of the top plate 1.2 to the center square.

[0043] 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 the action of its own weight and moves the one-way push member 6.2 to the bottom of the clamping member 5 until the lifting member 6.1 moves down to the lowest point. Since 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 top of the clamping rod 4, the one-way pusher 6.2 can rotate upward around the axis, so that the lifting member 6.1 can continue to move downward. After the lifting member 6.1 moves downward by a set distance and the one-way pusher 6.2 rotates upward around the axis by 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 the action of its own weight and abuts against the limiter 6.3.

[0044] When recycling (recycling means 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 high point position. 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. Since the buoyancy member 8 floats on the sea surface, the attachment frame 1 can be conveniently lifted by the connecting rope 7 during recovery. In the process of the connecting rope 7 lifting the attachment frame 1, the lifting member 6.1 moves upward first, and in the process of the lifting member 6.1 moving upward, since the limiting member 6.3 is located below the one-way push member 6.2, and the one-way push member 6.2 abuts against the limiting member 6.3 (limiting the one-way push member 6.2 from rotating downward), the one-way push member 6.2 will push the clamping rod 4 to rotate upward during the lifting member 6.1 moving upward, so that the clamping rod 4 is separated from the clamping interface 5.1. At this time, the protective plate 3 will rotate downward under the action of its own weight and abut against the edge of the base 1.1, so that the space between the top plate 1.2 and the base 1.1 is blocked by each protective plate 3, and the egg-attaching rope 2 and the squid eggs on the egg-attaching rope 2 are protected in the space enclosed by the top plate 1.2, the base 1.1 and each protective plate 3. In this way, when the attachment frame 1 is lifted by the connecting rope 7, the problem of the squid eggs falling off and being lost due to the impact of seawater can be effectively avoided. After the attachment frame 1 is lifted by the connecting rope 7, the collection of the squid eggs can be realized.

[0045] In this embodiment, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the state of the protection plate 3 can be the following: In one way, Figure 1As shown, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the end of the protective plate 3 away from the top plate 1.2 tilts upward. In this way, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the base 1.1 and the top plate 1.2 will be in an open state, so that the squid can enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 when laying eggs, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2.

[0046] In another embodiment, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the end of the protective plate 3 away from the top plate 1.2 tilts downward. In this way, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the space between the base 1.1 and the top plate 1.2 will be in an open state, so that the squid can enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 when laying eggs, lay eggs on the egg-attaching rope 2, and attach the squid eggs to the egg-attaching rope 2.

[0047] In the third mode, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the protective plate 3 is parallel to the top plate 1.2. Thus, when the clamping rod 4 is clamped into the corresponding clamping interface 5.1, the space between the base 1.1 and the top plate 1.2 is in an open state, so that the cuttlefish can enter the attachment frame 1 through the space between the base 1.1 and the top plate 1.2 when laying eggs, lay eggs on the egg-attaching rope 2, and attach the cuttlefish eggs to the egg-attaching rope 2.

[0048] In this embodiment, there are multiple one-way pushers 6.2. The one-way pushers 6.2 correspond to the clamping rods 4 one by one, and a limiter 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. In this way, when the attachment frame 1 is lifted by the connecting rope 7 during recycling, the lifting member 6.1 first moves upward to the high point position, and the one-way pusher 6.2 pushes the corresponding clamping rod 4 to rotate upward during the upward movement of the lifting member 6.1, so that the clamping rod 4 is separated from the clamping interface 5.1.

[0049] Of course, it should be noted that one one-way pushing member 6.2 can also correspond to two or more card-connecting rods 4. For example, a cross bar is provided at the end of the one-way pushing member 6.2. When it is recovered, during the process of lifting the attachment frame 1 by the connecting rope 7, the lifting member 6.1 first moves upward to the high point position. 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 card-connecting rods 4 to rotate upward, so that the card-connecting rod 4 is separated from the card interface 5.1.

[0050] Furthermore, the egg-attaching rope 2 is a nylon rope. Using a nylon rope as the egg-attaching rope 2 can increase the number of eggs laid by the squid on the egg-attaching rope 2. Of course, it should be noted that the egg-attaching rope 2 can also be other ropes. C-shaped buckle 5.2 Further, such as Figure 1 , Figure 3As shown, the clamping member 5 includes a C-shaped clamping member 5.2 with an opening facing upward. The C-shaped clamping member 5.2 is an elastic clamping member. The inner cavity of the C-shaped clamping member 5.2 forms the clamping interface 5.1. Both ends of the C-shaped clamping member 5.2 are provided with guide members 5.3 extending upward, and a guide opening 5.4 is formed between the guide members 5.3 at both ends of the C-shaped clamping member 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, and the clamping rod 4 can be guided by the guide opening 5.4 between the guide members 5.3 at both ends of the C-shaped clamping member 5.2, so as to ensure that the clamping rod 4 is smoothly clamped into the corresponding clamping interface 5.1. When recovering, when the attachment frame 1 is lifted by the connecting rope 7, the one-way pusher 6.2 can smoothly push the clamping rod 4 to rotate upward during the process of the lifting member 6.1 moving upward first, so as to ensure that the clamping rod 4 is smoothly separated from the clamping interface 5.1.

[0051] Specific embodiment 3: The rest of the structure of this embodiment refers to the specific embodiment 1, except that: In one implementation of this embodiment, Figure 4 As shown, the edge of the base 1.1 is provided with a plurality 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 the action of 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.

[0052] In another implementation of the present 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 abuts against 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 flow 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.

[0053] 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 falls within the protection scope of the technical solution of the present invention.
