[0036] Reference Figures 1 to 3 An embodiment of the present invention provides a net connection structure, which includes:

[0037] The clamping member 1 is used to be fixed on the netting post 5;

[0038] Rope 2;

[0039] The floating and sinking member 3 is sleeved on the rope 2 and detachably connected to the clamping member 1; the floating and sinking member 3 includes a float and / or a sinker;

[0040] The net body 4 is connected to the rope 2 and the floating and sinking parts 3.

[0041] Specifically, the net post 5 can be a steel pipe column, coated with an anti-corrosion paint. Multiple net posts 5 form a net cage frame supporting the net body 4. The clamping members 1 can be any structure with a clamping function, as long as they can conveniently clamp and secure the floating and sinking members 3. The number of clamping members 1 can be determined based on the specifications of the net body 4. They can be pre-fixed to the cylindrical surface of the net post 5 through welding, threading, or other methods, and arranged axially along the net post 5. The rope 2 can be a high-strength, low-density rope. The floating and sinking members 3 can be elongated cylindrical structures as shown. The number of floating and sinking members 3 can correspond to the number of clamping members 1, and they are installed one by one in series on the rope 2. The corresponding sides of the net body 4 can be sewn to the rope 2 and the floating and sinking members 3 installed on the rope 2 through a sewing process. This prevents the floating and sinking members 3 from slipping relative to the rope 2 by the traction of the net body 4.

[0042] During the specific installation process, the clamping piece 1 can be welded to the net column pile 5 in the height direction in advance, and the floating and sinking piece 3 can be put on the rope line 2 on the ground, so that the rope line 2 and the floating and sinking piece 3 together constitute the attachment and tensioning device of the net body 4; then the corresponding side edges of the net body 4 are sewn to the rope line 2 and the floating and sinking piece 3 put on the rope line 2 on the ground, so that the net body 4, the rope line 2 and the floating and sinking piece 3 together constitute a combined connecting piece; finally, the combined connecting piece is transported to a high altitude, and each floating and sinking piece 3 is installed on the corresponding clamping piece 1, and the floating and sinking piece 3 is clamped and fixed by the clamping piece 1; in this way, the installation connection between the net body 4 and the net column pile 5 is realized; when the net body 4 needs to be disassembled, repaired or replaced later, it is only necessary to loosen the clamping piece 1 and remove the rope line 2, the floating and sinking piece 3 and the net body 4 from the clamping piece 1 as a whole. Among them, when the floating and sinking part 3 is a float, it can pull the net body 4 upward under the buoyancy of the aquaculture water body; when the floating and sinking part 3 is a sinker, it can sink in the aquaculture water body and drive the net body 4 to be pulled downward; when a float is set at the upper part of the net body 4 and a sinker is set at the lower part, the net body 4 can be fully extended in the aquaculture water body through the joint action of the floating and sinking parts 3.

[0043] The above-mentioned net connection structure and corresponding installation connection method greatly reduce the high-altitude operation time during the installation of the net, improve the installation efficiency, and realize the convenient disassembly, assembly and replacement of the net body 4.

[0044] Optionally, refer to Figures 1 to 3 The clamping member 1 includes a first clamping plate 11 and a second clamping plate 12; the first clamping plate 11 is provided with a first accommodating groove 111, and the second clamping plate 12 is provided with a second accommodating groove 121; the second clamping plate 12 is movably connected to the first clamping plate 11 so that the first accommodating groove 111 and the second accommodating groove 121 are clamped on the floating and sinking member 3.

[0045] The second splint 12 can be directly or indirectly connected to the first splint 11 by means of linear sliding, rotation, etc. with the help of sliding grooves, rotating shafts and other structures, so as to control the second accommodating groove 121 to approach or move away from the first accommodating groove 111 along a preset moving path, so that the floating and sinking part 3 can be conveniently clamped by matching the first accommodating groove 111 with the second accommodating groove 121; after clamping, the second splint 12 can be fixed in the current position by connecting devices such as pins, snaps, and threaded fasteners to prevent the second splint 12 from moving relative to the first splint 11 and causing the floating and sinking part 3 to loosen.

[0046] Optionally, refer to Figures 1 to 3 An elastic body (not shown in the figure) is provided in the first receiving groove 111 and / or the second receiving groove 121, and the elastic body is in contact with the floating and sinking member 3. By providing the elastic body, its elastic force can be utilized to fully fit with the floating and sinking member 3, thereby increasing the clamping force of the first receiving groove 111 and the second receiving groove 121 on the floating and sinking member 3, improving the clamping stability, and preventing the floating and sinking member 3 from loosening; at the same time, it can also reduce the friction generated by direct contact between the floating and sinking member 3 and the first clamping plate 11 and the second clamping plate 12 made of metal, thereby reducing the degree of wear of the device and extending the service life of the device. Among them, the elastic body can be selected from a rubber sealing ring, which can be provided in the sealing ring groove at the edge position of the first receiving groove 111 and the second receiving groove 121.

[0047] Optionally, refer to Figures 1 to 3 The clamping member 1 also includes a fixing seat 13; the fixing seat 13 has a first side surface 131 and a second side surface 132 relative to each other, the first side surface 131 is used to be fixed on the net column pile 5, the first plywood 11 is fixed to the second side surface 132, and the second plywood 12 is rotatably connected to the second side surface 132.

[0048] By providing the fixing base 13, the portion of the clamping member 1 connected to the net post 5 and the portion clamping the floating and sinking member 3 can be prevented from interfering with each other, and a base can be provided for the movement of the second clamping plate 12 relative to the first clamping plate 11. Specifically, the first side surface 131 of the fixing base 13 can be welded to the net post 5, and the second clamping plate 12 can be rotatably connected to the second side surface 132 of the fixing base 13 via a rotating shaft structure; Figure 3 As shown, the second splint 12 can rotate around a horizontal rotation axis, and the horizontal rotation axis is set at the top or bottom end of the second splint 12 to ensure that the second splint 12 does not interfere with the first splint 11 during the rotation process, and can ensure that after the second splint 12 is opened around the horizontal rotation axis, there is enough avoidance space between the second splint 12 and the first splint 11 for the floating and sinking part 3 to be placed in the first receiving groove 111 of the first splint 11; when the floating and sinking part 3 is placed in the first receiving groove 111, the second splint 12 is rotated again to make the second receiving groove 121 fit on the floating and sinking part 3, so that the floating and sinking part 3 is clamped by the clamping action of the first receiving groove 111 and the second receiving groove 121.

[0049] Optionally, the edges of the first and second plates 11 and 12 are rounded, which can reduce wear caused by the edges of the first and second plates 11 and 12 contacting the net body 4 and other components.

[0050] Optionally, refer to Figures 1 to 3 A positioning portion 15 is provided on the second splint 12, and a matching portion (not shown in the figure) is provided on the second side surface 132. The positioning portion 15 is used to connect and cooperate with the matching portion; wherein, one of the positioning portion 15 and the matching portion is a positioning pin shaft, and the other of the positioning portion 15 and the matching portion is a positioning pin hole.

[0051] Specifically, the positioning pin shaft can be an ordinary pin or a spring pin; if an ordinary pin is used, a connecting through hole corresponding to the positioning pin hole can be opened on the second splint 12. When the second splint 12 is rotated to the preset position and the floating and sinking part 3 is clamped, the connecting through hole is opposite to the positioning pin hole. At this time, the ordinary pin can be passed through the connecting through hole and inserted into the positioning pin hole of the fixing seat 13; if a spring pin is used, the spring pin can be pre-connected to the second splint 12, and the plunger part of the spring pin faces the second side surface 132. When the second splint 12 is rotated to the preset position and the floating and sinking part 3 is clamped, the spring pin is opposite to the positioning pin hole. At this time, the plunger part of the spring pin will pop out under the action of elasticity and be clamped in the positioning pin hole; in the above manner, the movable second splint 12 can be fixed relative to the fixing seat 13, thereby realizing the positioning of the second splint 12.

[0052] Optionally, the positioning portion 15 and the matching portion can be provided in plurality, for example, Figure 3 The four shown are arranged around the rotation axis of the second clamping plate 12 to improve the positioning stability of the second clamping plate 12 through the connection and cooperation between the multiple positioning parts 15 and the matching parts.

[0053] Optionally, refer to Figures 1 to 3 A rotating shaft portion 14 is provided on the second side surface 132, the axial direction of the rotating shaft portion 14 is perpendicular to the extension direction of the second accommodating groove 121, and the second splint 12 is rotatably connected to the rotating shaft portion 14; at least two matching portions are provided on the second side surface 132, and the shortest straight-line distance between at least two matching portions and the rotating shaft portion 14 is equal.

[0054] As shown, the axis of the rotating shaft portion 14 is horizontally disposed and can be located at the top or bottom end of the second clamping plate 12 to ensure that the second clamping plate 12 does not interfere with the first clamping plate 11 during rotation. This ensures that, after the second clamping plate 12 is opened about the rotating shaft portion 14, sufficient clearance is reserved between the second clamping plate 12 and the first clamping plate 11 for the floating and sinking member 3 to be placed into the first receiving slot 111 of the first clamping plate 11. When at least two mating portions are spaced apart on the second side surface 132, and the shortest straight-line distances between each mating portion and the rotating shaft portion 14 are equal, the positioning portion 15 can connect to any mating portion as the second clamping plate 12 rotates, thereby positioning the second clamping plate 12 in at least two positions on the fixing seat 13. For example, the second clamping plate 12 can be positioned in the fully open position during installation of the net body 4, making it easier for the operator to place the floating and sinking member 3 into the first receiving slot 111.

[0055] Optionally, refer to Figures 1 to 3 The shaft portion 14 includes a connecting bolt and a locking washer; the connecting bolt is locked to the second side surface 132, the second splint 12 is rotatably connected to the connecting bolt, and the locking washer is sleeved on the connecting bolt; the connecting bolt is used to press the second splint 12 onto the second side surface 132 through the locking washer.

[0056] As shown, when the connecting bolt is not in a locked state, the second clamping plate 12 can rotate on the connecting bolt. When the second clamping plate 12 is rotated to a preset position, the connecting bolt can be tightened to press the second clamping plate 12 against the fixing seat 13 via the screw head of the connecting bolt. A locking washer is positioned between the second clamping plate 12 and the screw head of the connecting bolt. In one embodiment, a serration is provided on one or both end surfaces of the locking washer. When the screw head of the connecting bolt presses the locking washer against the second side surface 132, the serration engages with the second side surface 132 and / or the screw head of the connecting bolt, thereby increasing friction and preventing the connecting bolt from rotating relative to the fixing seat 13 and loosening, thereby improving installation stability.

[0057] Optionally, refer to Figures 1 to 3 The net connection structure includes multiple clamping members 1, which are spaced apart and arranged on the net posts 5. A plurality of floating and sinking members 3 are mounted on the rope line 2, each of which is detachably connected to a corresponding clamping member 1. The number of clamping members 1 is greater than or equal to the number of floating and sinking members 3. The provision of multiple floating and sinking members 3 and clamping members 1 increases the number of fixing points of the net body 4, thereby improving the connection stability of the net body 4. When the number of clamping members 1 exceeds the number of floating and sinking members 3, the operator can select the connection position of the floating and sinking members 3 according to actual needs, allowing a certain degree of adjustability in the height direction of the net body 4, thereby improving the applicability of the net connection structure.

[0058] Optionally, the rope 2 is a polyethylene rope.

[0059] Optionally, the floating and sinking member 3 is made of polyethylene.

[0060] Polyethylene material has the characteristics of high specific strength, high specific modulus, low density, low elongation at break, large work at break, strong energy absorption, good impact resistance and cut resistance, corrosion resistance, and wear resistance. It can reduce the weight while ensuring the strength and service life of the rope 2; and when the floating and sinking part 3 is a float, the low density characteristics of polyethylene can ensure that it floats on the surface of the aquaculture water body.

[0061] Optionally, a resin layer is provided on the rope 2 and / or the floating and sinking member 3.

[0062] By applying a resin layer, the wear resistance of the rope 2 and the floating and sinking parts 3 can be further improved, thereby extending their service life.

[0063] Optionally, the clamping member 1 is made of stainless steel.

[0064] Optionally, the material of the net body 4 is synthetic fiber, and the mesh shape of the net body 4 is diamond-shaped.

[0065] Synthetic fiber materials include but are not limited to polyester, nylon, acrylic, chloroprene, vinylon, spandex, and polyolefin stretch yarn, which have the characteristics of high strength, high wear resistance, and high weather resistance, and can ensure the quality and service life of the net body 4.
