Description

Technical Field

[0001] This utility model relates to the field of grouper aquaculture technology, and in particular to a deep-sea cage grouper spawning promotion device. Background Technology

[0002] Groupers are widely distributed in tropical and subtropical waters. They vary considerably in size, with most species being large, some reaching over 1 meter or even 2 meters in length, while smaller groupers are less than 20 cm long. They exhibit unique developmental characteristics, such as significant elongation and contraction of the dorsal and pelvic fin spines during larval and juvenile development. Groupers are benthic fish; adults primarily inhabit coral reefs and nearshore rocky reefs, while juveniles prefer seagrass beds and mangrove forests.

[0003] The process of inducing spawning in grouper involves several key steps. First is the selection and rearing of broodstock. Before the breeding season, strong, active male and female broodstock with no external injuries are selected and kept in indoor tanks. They are then fed ample fresh, high-quality feed to enhance their nutrition and promote normal gonadal development. When the female's gonads reach the appropriate stage of development, spawning is artificially induced by injection of drugs such as HCG and LPH-A. Simultaneously, HCG is injected into the male to promote sperm production, and artificial insemination is then performed at the appropriate time. The eggs are buoyant and are collected in egg collection tanks during spawning. After separation, disinfection, and counting, the eggs are placed in hatching ponds for incubation.

[0004] However, the deep-sea conditions are complex, harsh, and changeable. Existing deep-sea cage-cage grouper spawning induction devices have low mechanization rates when facing harsh sea conditions. Manually catching groupers awaiting spawning is inefficient. Furthermore, when administering spawning-inducing injections to groupers, both hands are needed to hold the groupers still, which affects the injection operation. Moreover, groupers are prone to jumping around during the injection process, making it difficult to ensure the amount of spawning-inducing drug injected, thus affecting the spawning-inducing effect of groupers. Utility Model Content

[0005] In view of this, this utility model proposes a deep-sea cage-cultured grouper spawning promotion device to solve the problems mentioned above.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A deep-sea grouper spawning induction device includes a frame, floats, and a net cage. Two floats are located on the top sides of the net cage. The frame is located on the top surface of the two floats. A moving mechanism is located at the bottom of the frame. A support plate is connected to the bottom of the moving mechanism. A winding mechanism is located at both ends of the support plate. A pull rope is located at both ends of the winding mechanism and connected to a fishing net. A discharge pipe is located on the bottom side of the fishing net and a valve is located on the discharge pipe. A fixed support frame is located on the top surface of the floats. A guide groove is located on the top of the fixed support frame and a net cover is located on the top of the guide groove. A first electric push rod is located on the inner wall of the fixed support frame and connected to a pressure plate at its telescopic end. A horizontal plate is connected to the top of the support frame and a movable support frame is slidably connected to the bottom surface of the horizontal plate. A second electric push rod is located on the inner wall of the movable support frame and connected to a pressure plate at its telescopic end.

[0008] Preferably, the moving mechanism includes a lead screw, a moving block, and a first motor. The lead screw is rotatably disposed at the bottom of the frame, with one end rotatably connected to the frame and the other end passing through the frame and driven by the first motor, which is disposed on the side of the frame.

[0009] Preferably, the winding mechanism includes a U-shaped frame, a winding drum, a rotating shaft, and a second motor. The rotating shaft is located at the bottom of the U-shaped frame, with one end rotatably mounted on the U-shaped frame and the other end passing through the U-shaped frame and connected to the second motor. The second motor is located on the side of the U-shaped frame.

[0010] Preferably, the net also includes a straight rod, a rotating rod, and a telescopic rod. One end of each of the two rotating rods is hinged to both ends of the straight rod, and both ends of the telescopic rod are connected to the other ends of the rotating rod. The top of the fishing net is connected to the straight rod, the rotating rod, and the telescopic rod. One end of the pull rope is connected to both ends of the telescopic rod and the straight rod, and the other end is connected to a winding mechanism.

[0011] Preferably, the guide groove has a V-shaped cross-section and is made of stainless steel.

[0012] Preferably, the system also includes a T-shaped slider, wherein the bottom surface of the horizontal plate is provided with a T-shaped groove, the T-shaped slider is slidably disposed in the T-shaped groove, and the bottom of the T-shaped slider is connected to a movable support frame.

[0013] Preferably, the system also includes a cylinder and a temporary holding net, wherein the cylinder is located below the end of the guide channel, passes through the float, and is connected to the temporary holding net.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The spawning-inducing device uses a winding mechanism to drive the fishing net to catch grouper, which improves work efficiency. When injecting spawning-inducing drugs into grouper, pressure plates one and two are used to fix both ends of the grouper to prevent the grouper from jumping around during the injection process, ensuring the amount of spawning-inducing drugs injected, thereby improving the spawning-inducing effect of grouper.

[0016] 2. When the reeling mechanism lifts the rope on one side, causing the fishing net to tilt towards the discharge pipe, the telescopic rod is slowly shortened. The telescopic rod drives the two ends of the rotating rod to move closer together, causing the sides of the fishing net to move closer together. This concentrates the grouper on both sides towards the discharge pipe, which helps the grouper to be smoothly discharged from the discharge pipe onto the guide channel, preventing the grouper from remaining in the fishing net.

[0024] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0025] See Figures 1 to 5 This utility model provides a deep-sea grouper spawning promotion device in a net cage, comprising a frame 1, floats 2, and a net cage 12. Two floats 2 are located on either side of the top of the net cage 12. The frame 1 is located on the top surface of the two floats 2. A moving mechanism is located at the bottom of the frame 1, and a support plate 3 is connected to the bottom of the moving mechanism. A winding mechanism is located at both ends of the support plate 3, and pull ropes 11 are located at opposite ends of the winding mechanisms. The pull ropes 11 are connected to a fishing net 13, and a discharge pipe 14 is located on the bottom side of the fishing net 13. A valve 31 is provided on the discharge pipe 14. A fixed support frame 17 is provided on the top surface of the float 2. A guide groove 18 is provided on the top of the fixed support frame 17. A mesh cover 19 is provided on the top of the guide groove 18. A first electric push rod 24 is provided on the inner wall of the fixed support frame 17. A pressure plate 25 is connected to the telescopic end of the first electric push rod 24. A horizontal plate 20 is connected to the top of the support frame. A movable support frame 23 is slidably connected to the bottom surface of the horizontal plate 20. A second electric push rod 26 is provided on the inner wall of the movable support frame 23. A pressure plate 27 is connected to the telescopic end of the second electric push rod 26.

[0026] Specifically, when the spawning induction device is working, the winding mechanism is first activated, releasing the pull rope 11 to lower the catching net 13 to the bottom of the net cage 12 for catching grouper. Then, the winding mechanism is activated again to reel in the pull rope 11, raising the catching net 13. Next, the guide trough 18 and the net cover 19 are connected and secured to the discharge pipe. The valve 31 is opened, and then the winding mechanism on the side away from the discharge pipe 14 is activated. This mechanism raises the pull rope 11 on one side, causing the catching net 13 to tilt towards the discharge pipe 14, discharging the grouper from the discharge outlet onto the guide trough 18. The operator operates from one side of the guide channel 18. By observation, the grouper requiring the injection of spawning-inducing drugs is intercepted at the end of the guide channel 18. Then, the first electric actuator 24 is activated. The telescopic end of the first electric actuator 24 extends, simultaneously moving the first pressure plate 25 towards the center, clamping one end of the grouper. The movable support frame 23 is then adjusted to slide to the other end of the grouper. Next, the second electric actuator 26 is activated. The telescopic end of the first electric actuator 24 extends, simultaneously moving the second pressure plate 27 towards the center, clamping the other end of the grouper. The spawning-inducing drug is then injected into the grouper. The spawning-inducing device uses a winding mechanism to drive the catching net 13 to catch the grouper, improving work efficiency. Furthermore, when injecting the spawning-inducing drug into the grouper, the first pressure plate 25 and the second pressure plate 27 are used to fix both ends of the grouper, preventing it from jumping around during the injection process and ensuring the amount of spawning-inducing drug injected, thereby improving the spawning-inducing effect on the grouper.

[0027] Preferably, the moving mechanism includes a lead screw 8, a moving block 10, and a first motor 7. The lead screw 8 is rotatably disposed at the bottom of the frame 1, with one end rotatably connected to the frame 1 and the other end passing through the frame 1 and driven by the first motor 7. The first motor 7 is disposed on the side of the frame 1.

[0028] Understandably, the moving mechanism is used to drive the support plate 3 to move laterally. When the moving mechanism is working, the first motor 7 is started. The rotation of the first motor 7 drives the lead screw 8 to rotate. The lead screw 8 is threadedly connected to the moving block 10, driving the moving block 10 to move linearly along the axis of the lead screw 8, thereby driving the support frame to move laterally. This is suitable for deep-sea environments where repeated positioning is required.

[0029] Preferably, the winding mechanism includes a U-shaped frame 4, a winding drum 5, a rotating shaft 6, and a second motor 9. The rotating shaft 6 is located at the bottom of the U-shaped frame 4, with one end rotatably mounted on the U-shaped frame 4 and the other end passing through the U-shaped frame 4 and connected to the second motor 9. The second motor 9 is located on the side of the U-shaped frame 4.

[0030] Specifically, the winding mechanism is driven by a second motor 9, which can not only quickly retract or release the pull rope 11, but also achieve precise winding and unwinding control. When the winding mechanism is working, the second motor 9 is started, and the rotation of the second motor 9 drives the winding drum 5 to rotate, which in turn retracts or releases the pull rope 11 at both ends.

[0031] Preferably, the net also includes a straight rod 28, a rotating rod 29, and a telescopic rod. One end of each of the two rotating rods 29 is hinged to both ends of the straight rod 28. Both ends of the telescopic rod are connected to the other ends of the rotating rods 29. The top of the fishing net 13 is connected to the straight rod 28, the rotating rod 29, and the telescopic rod. One end of the pull rope 11 is connected to both ends of the telescopic rod and the straight rod 28, and the other end is connected to a winding mechanism thereon.

[0032] When the reeling mechanism lifts the pull rope 11 on one side, causing the fishing net 13 to tilt toward the discharge pipe 14, the telescopic rod is slowly shortened. The telescopic rod drives the two ends of the rotating rod 29 to move closer together, causing the sides of the fishing net 13 to move closer together, concentrating the grouper on both sides toward the discharge pipe 14. This facilitates the smooth discharge of the grouper from the discharge pipe 14 onto the guide trough 18, preventing the grouper from remaining in the fishing net 13.

[0033] Preferably, the guide groove 18 has a V-shaped cross-section and is made of stainless steel.

[0034] Understandably, when grouper is discharged from discharge pipe 14 onto guide channel 18, the V-shaped guide channel 18 helps the grouper maintain its body posture, the stainless steel surface has low friction, which helps the grouper slide in the guide channel 18; stainless steel has strong corrosion resistance, making it suitable for use in deep-sea cages 12.

[0035] Preferably, a T-shaped slider 22 is also included. The bottom surface of the horizontal plate 20 is provided with a T-shaped groove 21. The T-shaped slider 22 is slidably disposed in the T-shaped groove 21. The bottom of the T-shaped slider 22 is connected to the movable support frame 23.

[0036] When one end of the grouper is clamped by the pressure plate 25, the operator slides the support frame 23 according to the position of the other end of the grouper. The T-shaped slider 22 slides in the T-shaped groove 21, which has good guidance and stability.

[0037] Preferably, the system also includes a cylinder 15 and a temporary holding net 16, wherein the cylinder 15 is located below the end of the guide groove 18, passes through the float 2 and is connected to the temporary holding net 16.

[0038] After the injection of fertilization-inducing drugs into the grouper is completed, the grouper is slid out of the guide trough 18 and falls into the cylinder 15. The grouper then enters the temporary holding net 16 through the cylinder 15. The temporary holding net 16 is located in seawater, which helps maintain the health of the grouper.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
