Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture equipment, and particularly relates to a snorkeling type floating aquaculture cage. Background Art

[0002] In recent years, with the rapid development of deep - sea and far - sea aquaculture technology, snorkeling type floating aquaculture cages have gradually become an important research direction of marine fishery equipment due to their characteristics such as adjustable water depth and strong wave resistance. Traditional circular aquaculture cages generally set up floating platforms on the sea surface. Aquaculture workers can walk on the floating platforms. On the one hand, they can check the structure of the cages, and on the other hand, they can observe the animals such as fish cultured in the cages. In order to ensure the safety of aquaculture workers, guardrails are generally installed on the floating platforms for the workers to hold. During the long - term offshore aquaculture process, the sea waves will impact the entire aquaculture cage. The fixing rods used to connect the guardrails and the floating platforms will bear external forces in different directions. The wear of the fixing rods is different. If some fixing rods bear large impacts for a long time, they are prone to excessive damage, while some fixing rods have less wear due to less impact. Since the wear degrees of the fixing rods are different, the number of maintenance and repair times will increase, resulting in an increase in aquaculture costs. In addition, because the fixing rods cannot adjust their positions, they cannot adjust their positions to dynamically balance the structural stress and improve the wave resistance when the sea waves are large. Summary of the Invention

[0003] In view of this, the present invention provides a snorkeling type floating aquaculture cage, in which the positions of the columns can be adjusted, so that the wear of the columns can be unified, and at the same time, the structural stress can be balanced according to the sea conditions, extending the service life of the aquaculture cage.

DETAILED DESCRIPTION OF THE INVENTION

[0026] To better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0027] See Figures 1 to 5 , a snorkeling type aquaculture cage provided by the present invention includes an annular platform 1, a netting 2, a buoyancy chamber 3, an annular fence 4, a sleeve 5, a support column 6, and an adjustment mechanism. The annular platform 1 is arranged on the water surface, the netting 2 is located in the water, and its top surface is connected to the bottom surface of the annular platform 1. The buoyancy chamber 3 is arranged on the outer side wall of the annular platform 1. The annular fence 4 is located above the annular platform 1. The sleeve 5 is slidably sleeved on the annular fence 4. The top end of the support column 6 is detachably connected to the bottom surface of the sleeve 5, and its bottom end is detachably connected to the upper surface of the annular platform 1. The adjustment mechanism includes a moving platform 7, an electric turntable 8, a rotating plate 9, a first electric push rod 10, a U-shaped frame 11, a metal arc plate 12, a clamping spring 13, an electromagnet 14, a wave sensor 15, a wind direction and wind speed sensor 16, and a main control unit 17. An annular track 18 is arranged on the upper surface of the annular platform 1. The moving platform 7 moves along the annular track 18. The electric turntable 8 is arranged on the top surface of the moving platform 7, and its rotating surface is connected to the bottom surface of the rotating plate 9. The first electric push rods 10 are symmetrically arranged on the top surface of the rotating plate 9, and their output shafts are connected to the side walls of the U-shaped frame 11. The opening of the U-shaped frame 11 faces away from the first electric push rod 10. The metal arc plates 12 are oppositely arranged in the U-shaped frame 11. The clamping spring 13 connects the convex surfaces of the metal arc plates 12 and the inner side walls of the U-shaped frame 11. The electromagnet 14 is arranged on the outer side wall of the U-shaped frame 11 and is located on one side of the metal arc plate 12. The wave sensors 15 are arranged at intervals on the outer wall of the annular platform 1 and are in contact with the water surface. The wind direction and wind speed sensor 16 is arranged on the top surface of the sleeve 5. The main control unit 17 is arranged on the outer side wall of the moving platform 7 and is electrically connected to the support column 6, the moving platform 7, the electric turntable 8, the first electric push rod 10, the electromagnet 14, the wave sensor 15, and the wind direction and wind speed sensor 16 respectively.

[0028] The overall aquaculture cage includes the annular platform 1 on the water surface and the netting 2 underwater. The netting 2 is distributed in a ring shape. Aquaculture fish can be cultured inside the annular platform 1 to prevent the fish from swimming outside. Above the annular platform 1, the annular fence 4 is connected by the support column 6. The annular fence 4 can be grasped by the staff walking on the annular platform 1 to increase stability and prevent the staff from swaying due to excessive sea waves. In addition, a number of buoyancy chambers 3 are arranged on the annular platform 1. The buoyancy chambers 3 can be inflated and deflated to adjust the buoyancy of the entire aquaculture cage, realizing snorkeling to adapt to different marine environments. For example, when the sea waves are large, the aquaculture cage can dive to avoid the waves, reduce damage, and improve stability.

[0029] For the support column 6, its top end is detachably connected to the sleeve 5, and the sleeve 5 is slidably arranged on the annular fence 4. In addition, the bottom end of the support column 6 is also detachably connected to the annular platform 1. When the bottom end of the support column 6 is separated from the annular platform 1, the support column 6 can move along the annular fence 4 together with the sleeve 5 to change its position. And if the top end of the support column 6 is also separated from the sleeve 5, the entire support column 6 can be disassembled, so that the position of the support column 6 can be replaced. An annular track 18 is arranged on the surface of the annular platform 1, and the moving platform 7 can move along the annular track 18. An electric turntable 8 is arranged on the moving platform 7, which can drive the rotating plate 9 to rotate. The first electric push rods 10 are oppositely arranged on the top surface of the rotating plate 9, and the first electric push rods 10 are used to drive the U-shaped frame 11 to move. When the U-shaped frame 11 moves to the outside of the support column 6, after the electromagnet 14 is powered off, the metal arc plate 12 can lose the magnetic force of the electromagnet 14, and under the action of the clamping spring 13, the metal arc plate 12 can clamp on the outside of the support column 6. Then, with the movement of the moving platform 7, the support column 6 and the sleeve 5 can be driven to move along the annular fence 4 to adjust the interval between the support columns 6. The wind direction sensor 16 can collect the sea wind direction. When the wind force in a certain sea direction is large, the interval between the support columns 6 in the windward direction can be reduced to balance the force on the structure and improve the overall stability. And a number of wave sensors 15 arranged on the annular platform 1 can collect wave data. The main control unit 17 can convert the wave data into the sea wave impact force borne by the annular platform 1 and the support column 6. Different impacts will correspond to different losses of the support column 6. Based on the different losses, the two U-shaped frames 11 can clamp the support columns 6 with different losses. Then, the electric turntable 8 can drive the rotating plate 9 to rotate, so that after the support column 6 leaves below the annular fence 4, the moving platform 7 drives the support column 6 to move to a designated position, so that the support columns 6 with different degrees of loss can be replaced in position, so that the loss degrees of all the support columns 6 are kept consistent, so as to facilitate maintenance at the same time and reduce the maintenance and aquaculture costs.

[0030] Preferably, it further includes a mounting seat 19. The mounting seat 19 is arranged on the bottom surface of the sleeve 5. The support column 6 includes a hollow tube 20, a bi-axial motor 21, a lead screw 22, a sliding seat 23, a rotary motor 24 and a threaded rod 25. Threaded holes 26 are arranged on the bottom surface of the mounting seat 19 and the upper surface of the annular platform 1. The threaded holes 26 on the annular platform 1 are arranged at annular intervals. The bi-axial motor 21 is arranged on the inner side wall of the hollow tube 20, and its output shaft is connected to one end of the lead screw 22. The sliding seat 23 is slidably connected to the inner wall of the hollow tube 20. The lead screw 22 passes through the sliding seat 23 and is threadedly connected to the sliding seat 23. The rotary motor 24 is arranged on the side wall of the sliding seat 23, and its output shaft is connected to the end of the threaded rod 25. The threaded rods 25 are symmetrically arranged up and down for connecting with the threaded holes 26. The main control unit 17 is electrically connected to the bi-axial motor 21 and the rotary motor 24 respectively.

[0031] For the support column 6, a structure that is screwed to the mounting base 19 and the annular platform 1 is adopted. Threaded holes 26 are provided on the bottom surface of the mounting base 19 at the bottom of the sleeve 5 and the upper surface of the annular platform 1. Inside the hollow tube 20, threaded rods 25 are symmetrically arranged up and down. The double-shaft motor 21 can drive the lead screw 22 to rotate. The sliding seat 23 is used to convert the rotational motion of the lead screw 22 into a linear motion, thereby driving the rotary motor 24 to move. The sliding seats 23 arranged up and down move in opposite directions when moving. Therefore, the threaded rods 25 also move in opposite directions. The rotary motor 24 can drive the threaded rods 25 to rotate, so that the threaded rods 25 can be screwed to the threaded holes 26 or unscrewed from the threaded holes 26, realizing the detachable connection with the mounting base 19 and the annular platform 1. When the metal arc plate 12 in the U-shaped frame 11 clamps the outer wall of the hollow tube 20, the threaded rods 25 can be rotated and lifted to realize the detachable connection of the support column 6 with the mounting base 19 and / or the annular platform 1.

[0032] Preferably, the support column 6 further includes a bearing plate 27 and a guide rod 28. The bearing plates 27 are symmetrically arranged on the inner side wall of the hollow tube 20 and are located on the upper and lower sides of the double-shaft motor 21. The end of the lead screw 22 away from the double-shaft motor 21 is rotatably connected to the bearing plate 27. One end of the guide rod 28 is connected to the bearing plate 27, and the other end passes through the sliding seat 23. The support column 6 further includes a bearing seat 29. The bearing seat 29 is arranged on the bearing plate 27, and the end of the lead screw 22 away from the double-shaft motor 21 is connected to the bearing seat 29.

[0033] When the double-shaft motor 21 drives the lead screw 22 to rotate, the end of the lead screw 22 can rotate under the support of the bearing seat 29. The guide rod 28 is arranged through the sliding seat 23. When the sliding seat 23 converts the rotational motion of the lead screw 22 into a linear motion, the sliding seat 23 can move along the guide rod 28. The sliding seat 23 is limited by the guide rod 28 to ensure that the rotary motor 24 does not shift when moving.

[0034] Preferably, it further includes a second electric push rod 30 and an abutting plate 31. The second electric push rod 30 is arranged on the inner side wall of the sleeve 5, and its output shaft is connected to the abutting plate 31. The annular fence 4 is located between the abutting plates 31. The main control unit 17 is electrically connected to the second electric push rod 30.

[0035] When the support column 6 needs to drive the sleeve 5 to move, the second electric push rod 30 can drive the abutting plate 31 away from the annular fence 4. When the support column 6 needs to be connected to the mounting base 19, the second electric push rod 30 can drive the abutting plate 31 to abut against the outer wall of the annular fence 4. At this time, the threaded rod 25 can be stably screwed to the mounting base 19, avoiding the movement of the sleeve 5 during the screwing process.

[0036] Preferably, it further includes a gasket 32, and the gasket 32 is arranged on the opposite side walls of the abutting plate 31 and the concave surface of the metal arc plate 12.

[0037] The arranged gasket 32 can increase the friction force, so as to facilitate the sleeve 5 and the annular fence 4 to form an integral body, and ensure that the metal arc plate 12 firmly clamps the support column 6.

[0038] Preferably, the mobile platform 7 includes a box body 33, electric walking wheels 34 and auxiliary wheels 35. The bottom surface of the box body 33 extends into the annular track 18. The electric walking wheels 34 are arranged at the bottom of the box body 33 and are in contact with the bottom surface of the annular track 18. The auxiliary wheels 35 are arranged on the side wall of the box body 33 and are in contact with the inner wall of the annular track 18. The main control unit 17 is arranged on the side wall of the box body 33 and is electrically connected to the electric walking wheels 34.

[0039] When it is necessary to adjust the position of the support column 6, the electric walking wheels 34 can be started. The electric walking wheels 34 can drive the box body 33 to move along the annular track 18. The arranged auxiliary wheels 35 can facilitate the smooth movement of the box body 33 in the annular track 18.

[0040] Preferably, the adjusting mechanism further includes a limiting cylinder 36 and a connecting rod 37. The limiting cylinder 36 is arranged on the inner side wall of the U-shaped frame 11. The clamping spring 13 is located inside the limiting cylinder 36. One end of the connecting rod 37 extends into the limiting cylinder 36 and is connected to the clamping spring 13, and the other end is connected to the convex surface of the metal arc plate 12.

[0041] The electromagnet 14 can magnetically attract the metal arc plate 12, and the clamping spring 13 can push the metal arc plate 12 to move. When the metal arc plate 12 moves, the connecting rod 37 can move along the limiting cylinder 36, ensuring that the movement of the metal arc plate 12 will not deviate, and ensuring that the metal plate can firmly clamp and fix the support column 6.

[0042] Preferably, the adjusting mechanism further includes a transmitting tube 38 and a receiving tube 39. The transmitting tube 38 is embedded at the bottom end of the lower threaded rod 25. The receiving tube 39 is arranged on the inner bottom surface of the threaded hole 26 of the annular platform 1. The main control unit 17 is electrically connected to the transmitting tube 38 and the receiving tube 39 respectively.

[0043] To facilitate the positioning of the support column 6, the present invention is provided with a transmitting tube 38 and a receiving tube 39. When the support column 6 moves on the annular platform 1, it will pass above different threaded holes 26. The transmitting tube 38 can emit infrared light to the receiving tube 39. When the receiving tube 39 receives the infrared light, it can send a signal to the main control unit 17. The main control unit 17 can determine the position of the support column 6 according to the signal sent by the receiving tube 39 to determine whether the support column 6 is above the corresponding threaded hole 26, so as to drive the biaxial motor 21 and the rotating motor 24 to connect and fix the support column 6.

[0044] Preferably, it further includes a gas charging and discharging pipe 40, and the gas charging and discharging pipe 40 is arranged on the buoyancy tank 3.
