Description

Technical Field

[0001] This utility model relates to the field of fish farming cage technology, specifically a protective device for fish farming cages. Background Art

[0002] Cage aquaculture is a new technology in the development of intensive production in the aquaculture industry worldwide. It uses synthetic fiber netting or metal netting to assemble cages of a certain shape and size, which are then placed in suitable water bodies for fish farming. The fish in the cages have low activity levels and consume less energy, which is conducive to the conversion and accumulation of nutrients. It has the characteristics of high yield, low cost, low investment, and easy management.

[0003] Existing protective devices for fish farming cages mostly consist of a number of bar-shaped rods combined with T-joints to form a cubic frame. A net is also fitted on the outside of the cubic frame to prevent fish from escaping. After assembly, it can be placed in the water for use. However, during long-term use, because there are usually no supporting components between adjacent bar-shaped rods, the bar-shaped rods are easily detached from the T-joints due to collisions with floating objects in the water, which can cause the fish farming cage to fall apart. The overall protective effect is relatively poor, which is not conducive to the long-term use of fish farming cages. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-7 As shown, a protective device for fish farming cages includes a three-way connector 1, strip rods 2, and diagonal bracing rods 4. Twelve strip rods 2 are provided, and every three adjacent strip rods 2 are fixed together by the three-way connector 1. A fish-blocking net bag 16 is provided around the strip rods 2. Figure 2As shown, in actual use, the strip rod 2 and the three-way connector 1 can be used to assemble a cubic frame for enclosing fish. Cable ties are then used to secure the assembled cubic frame through the mesh of the fish-blocking net bag 16. This ensures water circulation while preventing fish from escaping from the cubic frame, thus completing the assembly of the fish cage. Two diagonal braces 4 are provided, forming a scissor structure. A pivot 5 is provided between the diagonal braces 4, rotatably connected to both ends of the diagonal braces 4. Each end of the diagonal brace 4 has a receiving cavity 7, with an inner pull rod 6 slidably connected coaxially inside. An adjustment component 8 is also included, located outside the diagonal brace 4, allowing for quick adjustment of the extension length of the inner pull rod 6 within the receiving cavity 7. A limit head 15 is fixedly connected to the end of the inner pull rod 6 furthest from the diagonal brace 4. By using the adjustment component 8, the inner pull rod 6 can be adjusted... One end of the limiting head 15 reaches each inner corner of the cube frame, which facilitates the subsequent protection of the fish farming cage. The quick-installation component 14 is set on the outside of the tee joint 1 to improve the installation speed of the diagonal brace 4. By setting the quick-installation component 14, the installation process of the diagonal brace 4 can be simplified and the installation difficulty of the diagonal brace 4 can be reduced. After the connection is completed, the inner tie rod 6 and the limiting head 15 can support each inner corner of the cube frame. This can effectively prevent the strip rod 2 from falling off the tee joint 1 due to collision with floating objects, thus improving the overall protection performance of the fish farming cage. A telescopic sleeve 13 is provided between the limiting head 15 and the diagonal brace 4. The telescopic sleeve 13 is connected to the limiting head 15 and the diagonal brace 4 respectively. By setting the telescopic sleeve 13, water can be prevented from flowing into the receiving cavity 7 through the gap between the inner tie rod 6 and the diagonal brace 4, and the dirt in the water can be prevented from affecting the normal use of the adjustment component 8.

[0026] The adjusting assembly 8 includes a fixed cylinder 81 fixed to one end opening of the receiving cavity 7. The bottom of the inner cavity of the fixed cylinder 81 has an internally threaded channel 82. A locking bolt 84, adapted to the internally threaded channel 82, is provided inside the internally threaded channel 82. A rotating block 86 is fixedly connected to one end of the locking bolt 84. An internal hexagonal groove 83 is provided on one side of the rotating block 86. A fixing groove 85, corresponding to the locking bolt 84, is provided on the outer side of the inner pull rod 6. The other end of the locking bolt 84 passes through the fixing groove 85. Figure 4 , Figure 7 As shown, the internal hexagonal groove 83 on the outer side of the rotating block 86 allows the operator to use an internal hexagonal wrench to rotate the locking bolt 84, moving the locking bolt 84 away from or closer to the fixing groove 85 on the outer side of the inner tie rod 6. This releases or restricts the slippage of the inner tie rod 6 inside the receiving cavity 7, which facilitates the subsequent installation and protection work of the diagonal brace 4, and allows the limiting head 15 at one end of the inner tie rod 6 to reach the various inner corner positions of the cube frame.

[0027] A flexible belt 10 is fixedly connected to one side of the fixed cylinder 81, and a water-blocking cover 9 is fixedly connected to one end of the flexible belt 10. A sealing ring 11 is fixedly connected to the inner wall of the water-blocking cover 9. A sealing groove 12 corresponding to the sealing ring 11 is opened on the outer side of the fixed cylinder 81, and the sealing ring 11 is located inside the sealing groove 12. Figure 7 As shown, by setting the sealing ring 11 and the sealing groove 12, the water-blocking cover 9 can be positioned and installed at the port of the fixed cylinder 81 before the fish cage is put into the water. This can prevent dirt in the water from entering the fixed cylinder 81 and affecting the fit between the internal thread channel 82 and the locking bolt 84.

[0028] The quick-install assembly 14 includes a corner guard 141 fixed to the outside of the tee connector 1. A retaining groove 145 is provided on the outside of the limiting head 15. A U-shaped retaining element 142 is provided inside the retaining groove 145. A through groove 143 corresponding to the U-shaped retaining element 142 is provided on the outside of the corner guard 141. The U-shaped retaining element 142 extends through both ends of the through grooves 143 and has a bend 144. Figure 3 , Figure 4 By passing the bent ends 144 of the U-shaped clip 142 through the through groove 143 on the corner guard plate 141, and then using the cooperation between the U-shaped clip 142 and the outer anti-reverse groove 145 of the limiting head 15, the limiting head 15 and the corner guard plate 141 can be assembled. After assembly, the inner pull rod 6 and the limiting head 15 can support each inner corner of the cube frame. This can effectively prevent the strip rod 2 from detaching from the tee joint 1 due to collision with floating objects, thus improving the overall protective performance of the fish farming cage. When it is necessary to disassemble the U-shaped clip 142, the bent ends 144 can be pressed to make the U-shaped clip 142 detach from the through groove 143. At this time, the limiting head 15 is no longer restricted and can be freely disassembled. The operation is convenient and easy to use.

[0029] The corner guard plate 141 and the U-shaped clip 142 are made of polyethylene or polycarbonate. Polyethylene or polycarbonate has stable physical and chemical properties, strong impact resistance, and good processing performance, making it suitable for mass production of small parts.

[0030] A fish-blocking net cover 17 is fixedly connected to the top of one side of the fish-blocking net bag 16. The free side of the fish-blocking net cover 17 is connected to the other side of the fish-blocking net bag 16 by a zipper. Figure 1 As shown, by setting up a fish-blocking cover net 17, which serves as the entrance and exit of the fish-blocking net bag 16, it is convenient for staff to put the fish to be farmed into the fish farming net cage or to take the fish out from the fish farming net cage.

[0031] The top outer sides of the four bar-shaped poles 2 are equipped with floats 3 to prevent the entire fish-blocking net bag 16 from touching the bottom. Figure 1 , Figure 2As shown, by setting up the float 3, the fish farming cage can be submerged in the water while floating, which makes it easier for staff to locate the fish farming cage and facilitates the management of the fish farming cage.

[0032] Working principle: First, the workers assemble a cube-shaped frame to enclose the fish by using the strip rod 2 and the three-way connector 1. Then, the restriction on the inner pull rod 6 inside the receiving cavity 7 is released by the adjusting component 8, so that the limiting head 15 at one end of the inner pull rod 6 reaches the corresponding inner corner position of the cube frame. This facilitates the subsequent installation and protection of the diagonal brace 4. After the limiting head 15 is in place, the quick-installation component 14 can quickly assemble the limiting head 15 and the corner guard plate 141. After assembly, the inner pull rod 6 and the limiting head 15 can support each inner corner of the cube frame. This can effectively prevent the strip rod 2 from detaching from the three-way connector 1 due to collision with floating objects, thus improving the overall protection performance of the fish farming net cage. Finally, the fish-blocking net bag 16 is placed around the cube frame and put into the water.
