DETAILED DESCRIPTION

[0041] 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.

[0042] See also Figure 1-16 , the utility model provides a technical solution:

[0043] A double-layer aquaculture cage with a flow-reducing blade structure with a variable angle, comprising an outer cage 7 and an inner cage 6 placed inside the outer cage 7;

[0044] A floating passage 5 is provided in the gap between the outer net box 7 and the inner net box 6;

[0045] The outer net box 7 mainly includes blades 1, an outer frame 3, a sinker 9 and an adjustment component;

[0046] The inner net cage 6 mainly includes inner net blades 8, round floats 11, inner net cage frames 12, water channels 13 and propellers 17.

[0047] The blades 1 are arranged inside the outer frame 3 , a sinker 9 is arranged at the bottom of the outer frame 3 , and an adjustment component is arranged at the corner position above the outer frame 3 .

[0048] The regulating assembly includes a large disc 2, a valve 4, a large gear 10, a small gear 14, a main rotating shaft 15, a rod 16 and a rotating shaft 18. The large disc 2 is arranged below the large gear 10, and the rotating shaft 18 is inserted in the middle of the large gear 10. The side of the large gear 10 is meshed with the small gear 14, and the middle part of the outer side of the small gear 14 is connected to the valve 4. The transmission connecting rod 16 is provided below the large disc 2, and the rod 16 is connected to the large disc 2 through a rotating mechanism. The connection between the large disc 2 and the rod 16 can rotate, and the rotation of the large disc 2 will drive the rod 16 to move. The main rotating shaft 15 is inserted below the outer frame 3, and the main rotating shaft 15 rotates relative to the outer frame 3.

[0049] Rods 16 are respectively arranged on both sides of the main shaft 15, and the rods 16 on both sides are connected to the large disc 2 through a rotating mechanism. A connecting rod is arranged below the rod 16, and the connecting rod is connected to the blade 1. The connection between the connecting rod and the blade 1 can rotate relative to each other. The rotating mechanism is connected in a three-axis rotating manner. The middle of the blade is the rotating shaft, and the other two shafts play a role in controlling the rotation and fixing the angle during the rotation of the blade. At the same time, combined with the gear mechanism, the angle adjustment of the outer layer flow reduction blade has two modes of machine adjustment and manual adjustment.

[0050] The control transmission mechanism is located at the upper corner of the hexagonal prism. The user can control the rotation angle of the gear by controlling the internal machine, thereby controlling the rotation angle of the flow-reducing blade. Manual adjustment is to turn the valve manually, and drive the blade rotation angle of the entire device through the gear transmission mechanism.

[0051] The blades on each side of the layer cage are connected together by four rods, and the four rods are divided into two upper and two lower ones. The blades are connected to the rotating shaft through the displacement of the rods, so as to realize the rotation and adjustment angle of the blades;

[0052] The gear transmission mechanism used in manual control has the advantage of saving effort;

[0053] The outer cage uses flow-reducing blades and an adjustable angle mechanism as the main body. The blades are made of tough and hard materials and have the advantages of preventing strong typhoons, strong currents, and shark attacks.

[0054] The top of the rotating shaft 18 is plugged into the outer frame 3, and the plugged portion can rotate relatively.

[0055] The inner cage adopts a hexagonal prism design, which makes it more resistant to wind and waves. There is a circular float in the center of the bottom of the inner cage, which acts as a float. The six columns connected to it provide buoyancy for the entire inner cage.

[0056] The inner net box frame 12 is provided with inner net blades 8, a circular float 11 is provided at the center of the bottom end of the inner net box frame 12, a water channel 13 is provided on one side of the circular float 11, and a propeller 17 is provided at the center of the water channel 13.

[0057] The inner cage adopts a hexagonal prism design, which makes it more resistant to wind and waves. There is a circular float in the center of the bottom of the inner cage, which acts as a float. The six columns connected to it provide buoyancy for the entire inner cage.

[0058] The propeller 17 is fixed inside the circular float 11 through a bracket.

[0059] The outer net box 7 and the inner net box 6 are both hexagonal column structures, and the floating passage 5 is connected to the outer net box 7; the inner net box 6 and the outer net box 7 are connected and bound by ropes.

[0060] Flow reduction blade angle adjustment workflow

[0061] The machine adjusts the blade angle by rotating the machine control shaft to adjust the rotation angle of the large and small discs. The rotation of the large gear drives the four connected rods to rotate clockwise or counterclockwise, so that the blades rotate around the main axis, and the rotation of one disc will be transmitted to the next.

[0062] The manual adjustment method is to twist through the gear transmission mechanism. When the worker adjusts, he manually turns the valve, which in turn drives the small gear 14 to rotate, and then uses the meshing teeth to drive the large gear 10 to rotate. The large gear 10 will drive the large disk 2 below to rotate, thereby driving the rotation of the device blade angle. The rotation of the large disk will also drive the disk under the blade to rotate, thereby realizing the rotation of the blade angle of the entire device as a whole.

[0063] The rising process of the inner cage

[0064] First, untie the connection between the inner and outer net cages, start the propeller, and generate lift to lift the inner net cage. The staff can stand on the floating aisle to clean and replace the nets.

[0065] 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.
