Description

Technical Field

[0001] The invention relates to an artificial egg attaching base, in particular to a bottom-sinking and swinging egg attaching device. Background Art

[0002] The three main types of spawning materials for squid in natural areas are seaweed, coral, and artificial debris. With the destruction of the marine environment, the abundance of these coral and seaweed spawning materials has been depleted and their numbers have plummeted, leading to the widespread use of artificial spawning materials as a supplement.

[0003] Currently, artificially placed squid spawning surfaces fall into two categories. One type mimics seaweed and sways with the ocean currents. While this swaying behavior helps attract squid to spawn, it also hinders the stable attachment of squid eggs. For example, Chinese Patent Publication No. CN201111350, titled "Artificial Squid Egg Attacher," mimics the shape of seaweed and sways with the ocean currents, hindering the stable attachment of squid eggs. The other type uses fixed attachments (e.g., an egg-laying rope fixed to a frame) that cannot sway with the ocean currents. While fixed attachments help stabilize the attachment of squid eggs, they do not attract squid to spawn. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a bottom-sinking swinging egg-laying device, which can not only help attract squid to lay eggs on the egg-laying rope, but also can fix the egg-laying rope after the squid eggs attached to the egg-laying rope reach a set amount, so as to improve the attachment stability of the squid eggs.

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

[0006] A bottom-sinking, swinging egg-attaching device comprising:

[0007] The base is provided with a plurality of guide rods, and the guide rods are provided with upper limit blocks and lower limit blocks;

[0008] The floating frame is provided with a sliding guide sleeve that cooperates with the guide rod. The sliding guide sleeve is located between the upper limit block and the lower limit block. The sliding guide sleeve can slide along the corresponding guide rod;

[0009] Under the action of the support spring, the sliding guide sleeve and the floating frame move upward along the guide rod and make the sliding guide sleeve rest on the upper limit block;

[0010] An egg-attaching rope is suspended below the floating frame and has a counterweight at its lower end; and

[0011] The egg-attached rope swing limit and locking device includes a limit locking plate that can move up and down along the guide pole, a swing limit hole arranged on the limit locking plate for limiting the swing angle of the egg-attached rope, a buoyancy airbag connected to the limit locking plate, and an adaptive trigger device. The buoyancy of the buoyancy airbag is greater than the sum of the gravity of the buoyancy airbag and the limit locking plate. The limit locking plate is located below the lower limit block, and the limit locking plate is against the lower limit block under the buoyancy of the buoyancy airbag. The egg-attached rope passes through the swing limit hole, and the counterweight is located Below the limit locking plate, the adaptive trigger device includes an inner channel arranged in one of the guide poles, an exhaust hole connecting the outer side surface of the guide pole and the inner channel, and an exhaust interface arranged on the guide pole and connected to the inner channel. The buoyancy airbag is provided with an airbag interface, and the airbag interface and the exhaust interface are connected by a hose. An upper sealing ring and a lower sealing ring are provided on the inner wall of the sliding guide sleeve that cooperates with the guide pole where the inner channel is located. When the sliding guide sleeve where the upper sealing ring is located is against the upper limit block, the exhaust hole is located between the upper sealing ring and the lower sealing ring.

[0012] In specific use, the bottom-sinking, swinging egg-laying device of this solution, when there are no squid eggs attached to the egg-laying rope, the sliding guide sleeve abuts against the upper limit block under the action of the support spring, and the limit locking plate abuts against the lower limit block under the buoyancy of the buoyancy airbag. At this point, the egg-laying rope can swing within the range of the swing limit hole under the influence of the ocean current (simulating the swaying of seaweed with the ocean current), thereby attracting squid to lay eggs on the egg-laying rope. When the squid eggs attached to the egg-laying rope reach a set amount, they overcome the force of the support spring, driving the sliding guide sleeve and floating frame downward along the guide pole. During this process, when the upper sealing ring moves below the vent hole, the gas in the buoyancy airbag is discharged through the hose, the internal channel, and the vent hole, allowing the limit locking plate to move downward along the guide pole under its own weight. When the limit locking plate moves downward along the guide rod, the limit locking plate will come into contact with the counterweight, and drive the sliding guide sleeve, the floating frame and the counterweight to move downward together until the counterweight is supported on the upper surface of the base. At this time, the egg-attaching rope is in a straight state, thereby fixing the egg-attaching rope. The egg-attaching rope will no longer swing with the action of the ocean current, thereby improving the attachment stability of the squid eggs on the egg-attaching rope.

[0013] Preferably, when the sliding guide sleeve abuts the upper stop and the limit locking plate abuts the lower stop, a gap is provided between the limit locking plate and the counterweight. This ensures that the egg-laying rope can swing within the swing limit hole under the influence of the ocean current (simulating the swaying of seaweed with the ocean current), thereby facilitating the attraction of squid for spawning on the egg-laying rope.

[0014] Preferably, when the sliding guide sleeve abuts against the upper limit block, a gap is provided between the counterweight and the upper surface of the base, and the counterweight is close to the upper surface of the base.

[0015] Preferably, the exhaust hole is located between the upper limit block and the lower limit block, and the exhaust hole is close to the upper limit block.

[0016] As preferred, the exhaust port is located above the upper limit block. In this way, the exhaust port and the sliding guide sleeve are distributed on the upper and lower sides of the upper limit block to prevent the exhaust port from affecting the sliding guide sleeve from moving along the guide rod.

[0017] Preferably, the buoyancy airbag is located above the floating frame, and is connected to the limit locking plate by a connecting rope. This prevents the buoyancy airbag from interfering with the movement of the floating frame along the guide pole, without affecting the limit locking plate's contact with the lower limit block under the buoyancy of the buoyancy airbag.

[0018] Preferably, the counterweight is spherical, and the outer diameter of the counterweight is larger than the inner diameter of the swing limiting hole.

[0019] Preferably, the buoyancy air bag is provided with an inflation nozzle, so that it is convenient to inflate the buoyancy air bag through the inflation nozzle and to operate it in practice.

[0020] Preferably, the support spring is sleeved on the guide upright, the lower end of the support spring abuts against the lower limit block, and the upper end of the support spring abuts against the sliding guide sleeve.

[0021] The present invention has the following beneficial effects: when there are no squid eggs attached to the egg-laying rope, the sliding guide sleeve abuts against the upper limit block under the action of the support spring, and the limit locking plate abuts against the lower limit block under the buoyancy of the buoyancy airbag. At this point, the egg-laying rope can swing within the range of the swing limit hole under the influence of the ocean current (simulating the swaying of seaweed with the ocean current), thereby facilitating the attraction of squid to lay eggs on the egg-laying rope. When the number of squid eggs attached to the egg-laying rope reaches a set amount, they overcome the force of the support spring, driving the sliding guide sleeve and floating frame downward along the guide pole. During this process, when the upper sealing ring moves below the vent hole, the gas in the buoyancy airbag is discharged through the hose, the internal channel, and the vent hole, allowing the limit locking plate to move downward along the guide pole under its own weight. When the limit locking plate moves downward along the guide rod, the limit locking plate will come into contact with the counterweight, and drive the sliding guide sleeve, the floating frame and the counterweight to move downward together until the counterweight is supported on the upper surface of the base. At this time, the egg-attaching rope is in a straight state, thereby fixing the egg-attaching rope. The egg-attaching rope will no longer swing with the action of the ocean current, thereby improving the attachment stability of the squid eggs on the egg-attaching rope.

[0039] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0040] Specific embodiment 1: Figure 1 、 Figure 2 As shown, a bottom-sinking, swinging egg-attaching device comprises a base 1, a floating frame 4, a support spring 3, an egg-attaching rope 5, and a swing-limiting and locking device for the egg-attaching rope. The base 1 can be a steel frame or concrete base. Its upper surface is flat. Several guide posts 2 are mounted on the base. In this embodiment, there are four guide posts. Each guide post is equipped with an upper limit block 2.1 and a lower limit block 2.2. The upper limit block is located near the upper end of the guide post.

[0041] The floating frame 4 is equipped with a sliding guide sleeve 4.1 that cooperates with the guide rods. The sliding guide sleeve corresponds one-to-one with the guide rods. The sliding guide sleeve is located between the upper and lower limit blocks and can slide along the corresponding guide rods, thereby causing the floating frame to slide up and down along the corresponding guide rods. Under the action of the support spring 3, the sliding guide sleeve 4.1 and the floating frame move upward along the guide rods, causing the sliding guide sleeve to abut against the upper limit block. Specifically, the support spring 3 corresponds one-to-one with the guide rods. The support spring 3 is mounted on the corresponding guide rod, with the lower end of the support spring abutting against the lower limit block and the upper end of the support spring abutting against the sliding guide sleeve.

[0042] The egg-attaching rope swing limiting and locking device includes a limit locking plate 7 that can move up and down along the guide upright, a swing limiting hole 7.1 provided on the limit locking plate for limiting the swing angle of the egg-attaching rope, a buoyancy airbag 8 connected to the limit locking plate, and an adaptive triggering device. The swing limiting hole passes through the upper and lower surfaces of the limit locking plate. The limit locking plate is provided with vertical guide holes corresponding one to one with the guide uprights, and the guide uprights pass through the corresponding vertical guide holes. The limit locking plate is located below the floating frame. The limit locking plate is located below the lower limit block. The buoyancy of the buoyancy airbag 8 is greater than the sum of the gravity of the buoyancy airbag and the limit locking plate. The limit locking plate rests on the lower limit block under the buoyancy of the buoyancy airbag.

[0043] The adaptive trigger device includes an inner channel 10 provided in one of the guide uprights, an exhaust hole 11 connecting the outer side surface of the guide upright and the inner channel, and an exhaust interface 12 provided on the guide upright and connected to the inner channel. The exhaust hole is located between the upper limit block and the lower limit block, and the exhaust hole is close to the upper limit block. The buoyancy airbag is provided with an airbag interface 8.1. The airbag interface and the exhaust interface are sealedly connected by a hose 9. An upper sealing ring 13 and a lower sealing ring 14 are provided on the inner wall of the sliding guide sleeve that cooperates with the guide upright where the inner channel is located. When the sliding guide sleeve where the upper sealing ring is located is against the upper limit block, the exhaust hole is located between the upper sealing ring and the lower sealing ring.

[0044] The upper end of the egg-attaching rope 5 is connected to the floating frame. The egg-attaching rope is suspended below the floating frame, and a counterweight 6 is provided at its lower end. The egg-attaching rope may be one or more. In this embodiment, multiple egg-attaching ropes are evenly distributed. The swing limit holes correspond to each egg-attaching rope. The egg-attaching rope passes through the corresponding swing limit hole 7.1, and the counterweight is located below the limit locking plate.

[0045] When the sliding guide sleeve abuts the upper limit block and the limit locking plate abuts the lower limit block, a gap is provided between the limit locking plate and the counterweight; in this embodiment, the gap is 1-5 cm. When the sliding guide sleeve abuts the upper limit block, a gap is provided between the counterweight and the upper surface of the base, and the counterweight is close to the upper surface of the base.

[0046] When the bottom-sinking and swinging egg-laying device of this embodiment is used,

[0047] When there are no squid eggs attached to the egg-attaching rope, the sliding guide sleeve rests on the upper limit block under the action of the support spring, and the limit locking plate rests on the lower limit block under the buoyancy of the buoyancy air bag. At this time, the egg-attaching rope can swing within the range of the swing limit hole under the action of the ocean current (simulating the swing of seaweed with the ocean current), which is conducive to attracting squid to lay eggs on the egg-attaching rope.

[0048] When the number of squid eggs attached to each egg-laying rope reaches a set value, the force of the support spring is overcome, driving the sliding guide sleeve and floating frame downward along the guide pole. During this process, when the upper sealing ring moves below the vent, the gas in the buoyancy bag is discharged through the hose, internal channel, and vent (the buoyancy bag deflates), causing the limit lock plate to move downward along the guide pole under its own weight. As the limit lock plate moves downward along the guide pole, it abuts the counterweight, driving the sliding guide sleeve, floating frame, and counterweight downward together until the counterweight rests on the upper surface of the base. At this point, the egg-laying rope is straightened, securing the rope and preventing it from swinging with the current, thereby improving the stability of the squid eggs attached to the rope.

[0049] In this embodiment, Figure 1 As shown, the counterweight 6 is spherical, and the outer diameter of the counterweight is larger than the inner diameter of the swing limit hole. In this embodiment, the inner diameter of the swing limit hole is 10-30 cm. For example, the inner diameter of the swing limit hole is 10 cm, 12 cm, 15 cm, 17 cm, 19 cm, 20 cm, 22 cm, 25 cm, or 30 cm. In this way, after the gas in the buoyancy airbag is discharged through the hose, the inner channel, and the exhaust hole, it can be ensured that the limit locking plate will rest on the counterweight, and drive the sliding guide sleeve, the floating frame, and the counterweight to move downward together until the counterweight is supported on the upper surface of the base. Of course, the counterweight can also be in the shape of a block, a column, or other shapes, as long as the buoyancy member cannot pass through the swing limit hole.

[0050] Further, such as Figure 1 、 Figure 2 As shown, the exhaust port 12 is located above the upper limit block 2.1. In this way, the exhaust port and the sliding guide sleeve are distributed on the upper and lower sides of the upper limit block to prevent the exhaust port from affecting the sliding guide sleeve from moving along the guide rod.

[0051] Further, such as Figure 1 As shown, a buoyancy bag 8 is positioned above the floating frame. A connecting rope connects the buoyancy bag to the stop-lock plate. The connecting rope passes through the floating frame. This prevents the buoyancy bag from interfering with the movement of the floating frame along the guide poles, while maintaining the stop-lock plate's position against the lower stop block under the buoyancy of the buoyancy bag.

[0052] The buoyancy airbag is provided with an inflation nozzle, which makes it easy to inflate the buoyancy airbag through the inflation nozzle and operate it in practice.

[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 fall within the scope of protection of the technical solution of the present invention.
