Description

Technical Field

[0001] The utility model belongs to the technical field related to aquaculture cages, and specifically relates to a bottom-sitting deep-sea aquaculture cage with an autonomous piling and fixing function. Background Art

[0002] Deep-sea aquaculture, as an efficient way to utilize marine biological resources, has received increasing attention worldwide. However, traditional deep-sea aquaculture cages often have problems such as poor stability and susceptibility to wind and waves, which seriously restrict the development of deep-sea aquaculture.

[0003] In order to solve these problems, technicians began to research and develop new deep-sea aquaculture cage structures. Among them, the bottom-seated deep-sea aquaculture cage with autonomous piling and fixing function is an innovative design. This cage is fixed to the seabed through autonomous piling, and has the advantages of good stability, strong wind and wave resistance, easy movement, and simple fixing, providing a new solution for deep-sea aquaculture industry. Utility Model Content

[0004] The utility model aims to provide a bottom-seated deep-sea aquaculture cage with an autonomous piling and fixing function, so as to solve the problems of poor stability and susceptibility to wind and waves proposed in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A bottom-seated deep-sea aquaculture cage with an autonomous piling and fixing function, comprising:

[0007] Support columns and a central support column connected internally to the support columns;

[0008] There are six supporting columns in total, and the six supporting columns form a hexagonal frame structure;

[0009] The six supporting columns are connected by trusses;

[0010] The sides of the support column are equipped with propellers and cameras, and the bottom sides of the support column are equipped with rollers;

[0011] The middle position of the six support columns is connected to a central support column through a connecting rod, and a hook is arranged at the top of the central support column, and an oblate bottom plate is installed at the bottom of the central support column;

[0012] A lower air bag and an upper air bag are installed on the truss.

[0013] Preferably, the bottom end of the support column is connected to the roller via a hydraulic telescopic rod.

[0014] Preferably, an infrared rangefinder is provided at the bottom end of the support column at the other side of the roller.

[0015] Preferably, the propeller is connected to the support column via a movable joint.

[0016] Preferably, a piling assembly is connected to the bottom end of the support column.

[0017] Preferably, the piling assembly comprises a hydraulic rod, a rotating motor and a pile column, the bottom end of the hydraulic rod is connected to the rotating motor, and the bottom end of the rotating motor is connected to the pile column.

[0018] Preferably, the piling assembly also includes a hydraulic rod, a rotating motor, a pile column, a drill bit, an anti-sliding block, a baffle, a block and a rotating shaft, a hydraulic rod is arranged inside the pile column, and the end of the hydraulic rod is connected to the rotating motor, the bottom end of the rotating motor is connected to the drill bit, and an anti-sliding block is arranged on the outside of the rotating motor, a baffle is arranged above the anti-sliding block and below the rotating motor, a block is arranged below the baffle near the anti-sliding block, and the rotating motor and the drill bit are connected through a rotating shaft transmission.

[0019] Compared with the prior art, the utility model provides a bottom-seated deep-sea aquaculture cage with an autonomous piling and fixing function, which has the following beneficial effects:

[0020] The main structure of the cage is composed of six support columns, forming a hexagonal frame, with the central support column located in the center to enhance the overall stability. Each support column is equipped with instruments and equipment such as propellers, rollers, hydraulic rods, infrared rangefinders and underwater cameras, which work together to achieve precise control and monitoring of the cage in the water;

[0021] The piling and fixing function of the cage is a highlight of the design. Each support column is equipped with a piling assembly, which uses one point of main fixation and six points of auxiliary fixation for piling. The central support column is the main fixing point, and the pile used is thicker and plays a leading role. The other six support columns serve as auxiliary fixing points. During the piling process, the infrared rangefinder monitors the flatness and height difference of the surrounding environment to determine whether the piling requirements are met. The hydraulic rod controls the height of the roller by telescoping to achieve contact between the support rod and the seabed;

[0022] The piling assembly includes a hydraulic rod, a rotating motor and a pile. The hydraulic rod is responsible for driving the pile to rotate and move downward, while monitoring the force value to determine whether the pile is firmly fixed. The piling assembly is used to fix the cage firmly on the seabed, solving the problem of poor stability and susceptibility to wind and waves. The cage is more solid and stable and will not move due to wind and waves. During non-piling operations, the drill bit prevents the pile from falling downward. When the cage needs to be recovered, the upper airbag opens and the propeller drives the device to float to the surface of the water. The positioning light plays a key role in this process, helping the staff to quickly determine the position of the cage on the sea surface;

[0023] In addition, the cage also uses airbag technology to increase buoyancy and reduce the burden on the propeller. The upper and lower airbags are inflated when the device needs to float to provide additional buoyancy. The inflation principle of the airbag is the same as that of the safety airbag, and sodium azide (NaN3) is used as the key substance inside. When the airbag is activated, sodium azide quickly decomposes and releases a large amount of nitrogen, which quickly fills the airbag;

[0024] In short, the design of this bottom-seated deep-sea aquaculture cage with autonomous piling and fixing function fully considers the complex environment and challenges of deep-sea aquaculture. Through innovative structural design and advanced technology application, the cage achieves stable bottom-seating, flexible movement, precise piling and fixing, and efficient monitoring and management. This will greatly improve the efficiency and safety of deep-sea aquaculture and promote the sustainable development of the aquaculture industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-9 , the utility model provides a technical solution:

[0038] A bottom-seated deep-sea aquaculture cage with an autonomous piling and fixing function, comprising:

[0039] A support column 1 and a central support column 6 connected inside the support column 1;

[0040] There are six support columns 1 in total, and the six support columns 1 form a hexagonal frame structure;

[0041] The breeding cage adopts a hexagonal frame structure, and various instruments and equipment are installed on the support rod 1, including propellers, rollers, hydraulic rods, infrared rangefinders, underwater cameras and other equipment.

[0042] The six supporting columns 1 are connected by trusses;

[0043] The sides of the support column 1 are both equipped with propellers 2 and cameras 5, and the bottom side of the support column 1 is equipped with rollers 9; the propeller is used as a propulsion device for the device to move in the water. Due to the support of the buoyancy of the upper and lower air bags, the propeller load is not very large, and the device can move more flexibly in the water;

[0044] In this technical solution, preferably

[0045] The middle position of the six support columns 1 is connected to a central support column 6 through a connecting rod, and a hook 7 is provided at the top of the central support column 6. An oblate bottom plate 4 is installed at the bottom of the central support column 6. The oblate bottom seat is used to expand the bottom support area and increase the stability of the device on the ground.

[0046] In this technical solution, further, preferably

[0047] The truss is equipped with a lower airbag 3 and an upper airbag 8. The upper airbag 3 will be opened and inflated when the device needs to float up for recovery. It is usually in the upper truss of the net cage. The lower airbag 8 is inflated and connected to the net cage during the process of finding a fixation and piling in the net cage. When the piling is completed, the lower airbag 8 is disconnected from the net cage and floats to the water surface to wait for recovery by the staff. The inflation process of the airbag uses chemicals for gas filling. The inflation principle is the same as that of the safety airbag. Sodium azide (NaN3) is set inside as a key substance. When the airbag is started, the airbag generator will cause the sodium azide to decompose rapidly and release a large amount of nitrogen, thereby quickly filling the airbag. The function of the upper and lower airbags is to increase the buoyancy of the device in the water, reduce the burden on the propeller, give the propeller more control space, and make the device more flexible.

[0048] In this technical solution, further, optionally

[0049] The upper end of the support column 1 is a positioning light. When the device encounters an uncontrollable situation underwater or floats to the surface for recovery, it will send a signal to the staff and turn on the positioning light to flash to locate the position;

[0050] Each support column 1 is equipped with a piling assembly. The cage is fixed with one point of main body and six points of auxiliary fixing. The piling is fixed by drilling holes on the seabed of the device using the ground rotation method. The central support column is the main body, and the piles used are thicker than those of other support columns, playing a leading role.

[0051] In this technical solution, further, preferably

[0052] The lower end of the support column 1 is equipped with a roller 9, which is connected to a hydraulic telescopic rod. The hydraulic telescopic rod adjusts the relationship between the roller and the support rod by controlling the height of the roller by telescoping. When the device moves in the sea, the roller cooperates with the propeller to act as an auxiliary wheel when moving underwater. When the infrared rangefinder monitors whether the surrounding environment is flat and whether the height difference can meet the basic requirements of piling, if it does, the hydraulic telescopic rod will shrink, and the lower end of the device support rod will contact the seabed surface to perform piling operations; the piling assembly is located inside each support column, and there is an opening at the lower end of the support column. The piling machine fixes the pile column to the seabed by rotating and pushing. The pile column and the piling mechanism are separable. When the device floats to the surface for recovery, the pile column remains on the seabed. The rotation and extrusion of the piling mechanism are realized by the rotating motor and the hydraulic rod respectively. The rotating motor achieves the task of piling by giving the pile column the required rotation force to turn the ground and cooperating with the propulsion force applied by the hydraulic rod. The hydraulic rod will feedback the force value to determine whether the pile column has been firmly fixed.

[0053] An infrared rangefinder 11 is provided at the bottom end of the support column 1 at the other side of the roller 9 .

[0054] The propeller 2 is connected to the support column 1 via a movable joint 12 .

[0055] like Figure 7 As shown, in the present technical solution, further, the bottom end of the preferred support column 1 is connected with a piling assembly.

[0056] The pile driving assembly includes a hydraulic rod 13, a rotating motor 14 and a pile column 15. The bottom end of the hydraulic rod 13 is connected to the rotating motor 14, and the bottom end of the rotating motor 14 is connected to the pile column 15. The hydraulic rod 13 is retracted, and the support rod 1 touches the ground. The central support column is first used for main fixation, and the six support columns are used for auxiliary fixation. The rotating motor starts to drive the pile column to rotate, and the hydraulic rod starts to push the rotating motor 14 and the pile column 15 downward. At the same time, the hydraulic rod 13 monitors the force it bears at all times, and uses this to determine whether the pile column is stable;

[0057] like Figure 8 and 9 As shown, in this technical solution, further, optionally

[0058] The piling assembly also includes a hydraulic rod 13, a rotary motor 14, a pile 15, a drill bit 16, an anti-sliding block 17, a baffle 18, a stopper 19 and a rotating shaft 20. The hydraulic rod 13 is arranged inside the pile 15, and the end of the hydraulic rod 13 is connected to the rotary motor 14, the bottom end of the rotary motor 14 is connected to the drill bit 16, and the anti-sliding block 17 is arranged outside the rotary motor 14, and a baffle 18 is arranged above the anti-sliding block 17 and below the rotary motor 14, and a stopper 19 is arranged below the baffle 18 and near the anti-sliding block 17. The rotary motor 14 is connected to the drill bit 16 through the rotating shaft 20, and the drill bit is located at the end of the pile to prevent the pile from falling downward when the pile is not in the piling operation.

[0059] The end of the hydraulic rod 13 is connected to the rotating motor 14. The hydraulic rod 13 pushes the drill bit 16 downward. A block 19 is provided under the rotating motor 14. The block 19 drives the pile column 15 to move downward with the drill bit 16. After the piling work is completed, the pile column 15 needs to be separated. 1. The hydraulic rod 13 contracts. Since the block 19 clamps the baffle 18 to drive the pile column 15 to move downward, the diameter of the drill bit 16 is smaller than the distance between the two blocks 19, so the drill bit 16 can be retracted into the pillar as the hydraulic rod 13 contracts. The hydraulic rod 13 adopts a three-stage telescopic structure, which has better telescopicity and meets the needs of the device.

[0060] When the device floats up for recovery, the upper airbag opens, the propeller drives the device upward, and the positioning light is turned on at the same time. The positioning light helps the staff to more quickly determine the position of the device on the sea surface during the recovery process, and the recovery work is carried out by pulling the hook on the top of the cage.

[0061] During underwater work, if an unsolvable fault is encountered and manual recovery is required, the positioning light can also be on.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
