Description

Technical Field

[0001] The utility model relates to the technical field of fish farming cage brackets, specifically a steel cage bracket. Background Technique

[0002] At present, such cage brackets are basically made of PE material, either injection molded or rotomolded, with a certain flexibility and seawater corrosion resistance. However, the disadvantage is that the strength for large cages is slightly poor, and slight deformation may occur under strong winds and waves or strong dragging. Moreover, the cages assembled with PE brackets are not convenient for carrying heavier auxiliary equipment, etc.

[0003] The existing steel structure cage brackets and PE buoyancy tubes are assembled by direct docking. When used in aquaculture waters, the swinging of the PE buoyancy tubes driven by water waves will cause long-term friction between the PE buoyancy tubes and the brackets, which is likely to cause friction to damage the surface layer of the PE buoyancy tubes, and then easily cause the PE buoyancy tubes to be damaged. Content of the Utility Model

[0004] The purpose of the utility model is to provide a steel cage bracket to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a steel cage bracket, including a support column and a limit ring. A sleeve is welded to the top of the support column. Two parallel limit rings are arranged below the support column. An outer support plate and an inner support plate are welded between the two sleeves. The inner support plate is parallel to the two outer support plates. A locking bolt a is connected between the two inner support plates. One end of the locking bolt a is connected through the pull rod. A PE buoyancy tube is connected through the inside of the limit ring. A buffer is arranged between the limit ring and the PE buoyancy tube. A notch is arranged on one side of the buffer, and a groove is arranged on the outer wall of the buffer. The buffer is clamped with the limit ring through the groove.

[0006] Preferably, a hanging net hook is welded to one side of the top of the support column, and a diagonal brace is welded between one side of the support column and one of the outer support plates.

[0007] Preferably, an anti-corrosion sleeve is sleeved on the outside of the limit ring. One end of the anti-corrosion sleeve is provided with two integrally formed connecting arms, and a locking bolt b is inserted between the two connecting arms.

[0008] Preferably, one end of the anti-corrosion sleeve away from the connecting arm is connected to one end of the outer support plate through a locking bolt c, and the anti-corrosion sleeve is of an inner concave structure.

[0009] Preferably, a lifting rope tube is perpendicularly welded to one side of the outer support plate and the inner support plate. A iron chain passes through the middle of the lifting rope tube, and a limit pin is inserted at the top end of the iron chain.

[0010] Preferably, a cross arm welded to the limiting ring is arranged between the outer support plate and the inner support plate, and through holes are formed in the surface of the cross arm.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this steel mesh cage support, the buffer member with a notch is butted into the limiting ring, so that the groove on the outer wall of the buffer member is clamped on the inner wall of the limiting ring. Subsequently, the PE buoyancy tube is inserted into the limiting ring. Thus, the connection between the PE buoyancy tube and the limiting ring can be buffered and protected by the buffer member, and the friction damage of the PE buoyancy tube by this steel mesh cage support can be avoided;

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a steel mesh cage support, including a support column 1 and a limiting ring 2. A sleeve 101 is welded to the top of the support column 1. Two parallel limiting rings 2 are arranged below the support column 1. An outer support plate 3 and an inner support plate 4 are welded between the two sleeves 101. The inner support plate 4 is arranged parallel between the two outer support plates 3. A locking bolt a401 is connected between the two inner support plates 4. The locking bolt a401 is connected through one end of a pull rod 402. A PE buoyancy tube 7 is connected through the inside of the limiting ring 2. A buffer member 5 is arranged between the limiting ring 2 and the PE buoyancy tube 7. The buffer member 5 is made of PE material. An opening 501 is provided on one side of the buffer member 5. A groove 502 is provided on the outer wall of the buffer member 5. The buffer member 5 is clamped with the limiting ring 2 through the groove 502.

[0024] During specific implementation, the two limiting rings 2 are welded and assembled through the outer support plate 3 and the inner support plate 4. Then, the buffer member 5 with the opening 501 is butted inside the limiting ring 2, so that the groove 502 on the outer wall of the buffer member 5 is clamped on the inner wall of the limiting ring 2. Subsequently, the PE buoyancy tube 7 is inserted through the limiting ring 2. Thus, the connection between the PE buoyancy tube 7 and the limiting ring 2 can be buffered and protected by the buffer member 5, and the friction of the steel mesh cage support on the PE buoyancy tube 7 can be avoided;

[0025] At the same time, the pull rod 402 is butted between the two parallel inner support plates 4, and then the locking bolt a401 is used to firmly connect the inner support plate 4 and the pull rod 402, so that the pull rod 402 horizontally leads out of the steel mesh cage support. Furthermore, two adjacent steel mesh cage supports can be combined and connected. By setting the pull rod 402, the distance between two adjacent steel mesh cage supports can be fixed, and the sliding of the connection between the steel mesh cage support and the PE buoyancy tube 7 can be prevented. By repeating the above operations, multiple steel mesh cage supports can be enclosed in an annular structure, and further, the PE buoyancy tube 7 can be enclosed in an annular aquaculture net cage structure.

[0026] Please refer to Figures 1 - 3A net hook 102 is welded on one side of the top of the support column 1, and an oblique brace is welded between one side of the support column 1 and one of the outer support plates 3. By welding the oblique brace between the support column 1 and the outer support plate 3, the vertical support part of the cage support can be strengthened to prevent the vertical cage support from deformation, and the cage support can also be reinforced to resist waves. By setting the net hook 102, the top of the aquaculture fishing net can be hung on the net hook 102, which is convenient for pulling up the aquaculture fishing net.

[0027] See also Figures 1 - 3 as well as Figure 7 The outer side of the limiting ring 2 is sleeved with an anti-corrosion sleeve 6, one end of the anti-corrosion sleeve 6 is provided with two integrally formed connecting arms 601, and a locking bolt b602 is inserted between the two connecting arms 601;

[0028] The end of the anti-corrosion sleeve 6 away from the connecting arm 601 is connected to one end of the outer support plate 3 through a locking bolt c603. The anti-corrosion sleeve 6 is a concave structure, and the concave structure of the anti-corrosion sleeve 6 can wrap the limiting ring 2 to prevent the anti-corrosion sleeve 6 from being offset when docking with the limiting ring 2.

[0029] During specific implementation, the connecting arm 601 at one end of the anti-corrosion sleeve 6 is docked at the end of one of the outer support plates 3, and the locking bolt b602 is used to fasten the connecting arm 601. The locking bolt b602 can be hooked onto one of the outer support plates 3, and then the other end of the anti-corrosion sleeve 6 is tightened, and the locking bolt c603 is used to penetrate the anti-corrosion sleeve 6 and lock it with the other outer support plate 3, so that the limit ring 2 can be protected by the anti-corrosion sleeve 6, and corrosion erosion can be slowed down when water waves impact the steel mesh box support.

[0030] See also Figures 1 - 4 A lifting rope tube 8 is vertically welded on one side of the outer support plate 3 and the inner support plate 4. The lifting rope tube 8 is used to facilitate the lifting of the net rope, thereby improving the strength of the net box support. An iron chain 9 runs through the middle of the lifting rope tube 8, and a limiting pin 10 is inserted at the top of the iron chain 9. The lifting rope tube 8 adopts a round tube or a square tube.

[0031] During specific implementation, the iron chain 9 is inserted into the lifting rope tube 8, and then the iron chain 9 is extended out of the bottom of the lifting rope tube 8 to connect with the net cable in the water. When the net needs to be changed or washed, the iron chain 9 is pulled upward through the limit pin 10 to lift the bottom of the net, thereby realizing the operation of changing or washing the net.

[0032] See also Figures 1 - 4 A cross arm 11 welded to the limit ring 2 is provided between the outer support plate 3 and the inner support plate 4. A through hole is provided on the surface of the cross arm 11. By providing the through hole on the surface of the cross arm 11, a PE thin tube can be inserted into the through hole, so that wiring can be routed in the PE thin tube, which is convenient for powering the electrical equipment on the steel mesh box support.

[0033] In summary, the sleeve 101 of the cage support is sleeved on the fence of the aquaculture cage, and the PE buoyancy tube 7 is inserted into the limit ring 2 for limitation. Then, adjacent two steel cage supports are combined and connected through the pull rod 402, and further multiple steel cage supports are enclosed into an annular structure, which is convenient for enclosing the aquaculture cage structure with the PE buoyancy tube 7 into a ring.
