Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an aquaculture cage with a reinforced and protective structure against wind and waves. Background Technology

[0002] In the practical application of aquaculture cages, the inadequacy of the cage support structure has become a key defect affecting their resistance to wind and waves. Traditional cages usually adopt a simple suspended cage design, with the cage only fixed to the frame at the upper edge, and the lower part only provided limited restraint by a few sinkers or counterweights. This support method has serious problems in wind and wave environments. Under the periodic impact of waves, the cage lacks effective lateral support, causing the cage to swing significantly, resulting in poor wind and wave resistance. Therefore, there is an urgent need for an aquaculture cage with a wind and wave resistant and reinforced protective structure. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed aquaculture cage with a reinforced and protective structure to resist wind and waves, thereby solving the aforementioned problems.

[0005] It also includes:

[0006] A connecting ring is fixedly installed at the bottom of the net body. Several ropes are evenly distributed with rounded corners at the bottom of the floating frame and the connecting ring. Anchor nails are fixedly installed at the lower ends of the ropes.

[0007] The fixed posts are of several kinds, with equal rounded corners distributed at the bottom of the floating frame and the top of the connecting ring. The fixed posts are located on the outer side of the net body, and one end of the fixed post is rotatably provided with a flipping rod through a shaft and bearing.

[0008] The connecting rods consist of several rods, which are distributed on the outer wall of the mesh with equal rounded corners. The two ends of the connecting rods are rotatably connected to the upper and lower flipping rods respectively through shafts and bearings. The flipping rods are equipped with positioning and reinforcement mechanisms.

[0009] Furthermore, the positioning and reinforcement mechanism includes:

[0010] The reinforcing sleeve consists of two sleeves, which are movably fitted onto both ends of the flipping rod. The two sleeves are movably fitted onto the fixed post and the connecting rod, respectively. Several connecting blocks are distributed with equal rounded corners on the upper and lower sides of the inside of the reinforcing sleeve. The connecting blocks are movably set in the strip groove opened on the flipping rod.

[0011] The movable blocks are two in number, which are respectively movably arranged on the upper and lower sides inside the flipping rod. The connecting block is fixedly arranged on the movable blocks. Two springs are fixedly arranged inside the flipping rod, and one end of each spring is fixedly connected to the two movable blocks respectively.

[0012] Furthermore, the flipping rod has annular grooves on the upper and lower sides of the strip groove, and a sealing ring is fixedly sleeved in the annular groove, and the sealing ring is movably in contact with the inner wall of the reinforcing sleeve.

[0013] Furthermore, both the fixed column and the connecting rod are provided with limit grooves, and one end of the reinforcing sleeve is configured to cooperate with the limit groove.

Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a floating frame 1 and a net body 2. The net body 2 is fixedly installed at the bottom of the floating frame 1, and a reinforcing ring 16 is fixedly installed at the top of the floating frame 1. A reflective strip 17 is fixedly installed on the outer ring wall of the reinforcing ring 16. The reinforcing ring 16 can improve the structural strength of the floating frame 1 and reduce the deformation of the floating frame 1 due to external forces. At the same time, through the reflective characteristics of the reflective strip 17, it is also convenient for workers to find the net cage in poor lighting conditions such as at night.

[0025] It also includes:

[0026] Connecting ring 3, the connecting ring 3 is fixedly set at the bottom of the net body 2, and several ropes 4 are evenly distributed at the bottom of the floating frame 1 and the connecting ring 3 with rounded corners. Anchor nails 5 are fixedly set at the lower end of the ropes 4.

[0027] Fixed posts 6, there are several fixed posts 6, which are distributed at the bottom of the floating frame 1 and the upper part of the connecting ring 3 with equal rounded corners. The fixed posts 6 are located on the outside of the net body 2. One end of the fixed post 6 is rotatably provided with a flipping rod 7 through a shaft and bearing.

[0028] Connecting rod 8, there are several connecting rods 8, which are distributed on the outer side wall of the mesh body 2 with equal rounded corners. The two ends of the connecting rod 8 are rotatably connected to the upper and lower flip rods 7 respectively through shafts and bearings. The flip rods 7 are provided with positioning and reinforcement mechanisms 9.

[0029] The positioning and reinforcement mechanism 9 includes:

[0030] Two reinforcing sleeves 9-1 are movably fitted onto the two ends of the flipping rod 7, and the two reinforcing sleeves 9-1 are movably fitted onto the fixed post 6 and the connecting rod 8, respectively. Several connecting blocks 9-2 are distributed with equal rounded corners on the upper and lower sides of the inside of the reinforcing sleeve 9-1. The connecting blocks 9-2 are movably set in the strip groove 10 opened on the flipping rod 7. The other end of the reinforcing sleeve 9-1 is rotatably fitted with an internal threaded cylinder 14 through a bearing. The flipping rod 7 is provided with a threaded section 15 that cooperates with the internal threaded cylinder 14. When it is necessary to flip the reinforcing sleeve 9-1 and the flipping rod 7, the position of the reinforcing sleeve 9-1 can be limited by the cooperation of the threaded section 15 and the internal threaded cylinder 14, so as to prevent the reinforcing sleeve 9-1 from moving freely and affecting the convenience of the flipping rod 7 flipping operation.

[0031] Two movable blocks 9-3 are movably disposed on the upper and lower sides inside the flipping rod 7, respectively. A connecting block 9-2 is fixedly disposed on the movable blocks 9-3. Two springs 9-4 are fixedly disposed inside the flipping rod 7, with one end of each spring 9-4 fixedly connected to the two movable blocks 9-3. The positioning and reinforcement mechanism 9 can not only realize the flipping positioning of the connection between the two ends of the flipping rod 7 and the fixed column 6 and the connecting rod 8, but also realize the reinforcement of the connection, improving the stability of the support assembly of the net body 2 composed of the flipping rod 7, the fixed column 6 and the connecting rod 8, so that the net cage can have stronger wind and wave resistance. Annular grooves 11 are opened on the flipping rod 7 at the upper and lower sides of the strip groove 10. The inner fixed sleeve 11 is equipped with a sealing ring 12, which is movable and abuts against the inner wall of the reinforcing sleeve 9-1. The sealing ring 12 can improve the sealing performance of the gap between the reinforcing sleeve 9-1 and the flipping rod 7, and prevent water from seeping into the interior of the flipping rod 7 and affecting the spring 9-4. The fixed column 6 and the connecting rod 8 are both provided with limit grooves 13. One end of the reinforcing sleeve 9-1 is matched with the limit groove 13. When the reinforcing sleeve 9-1 and the flipping rod 7 are flipped to the horizontal state, the cooperation between the reinforcing sleeve 9-1 and the limit groove 13, as well as the pushing force applied by the spring 9-4 to the moving block 9-3, can realize the limit of the reinforcing sleeve 9-1 and the flipping rod 7 in this state, thereby facilitating the storage of the cage.

[0032] When using this utility model, the floating frame 1 floats on the water surface, the connecting ring 3 sinks and the net body 2 unfolds, so that the reinforcing sleeve 9-1 and the flipping rod 7 are flipped to the vertical state. At this time, the moving block 9-3 is affected by the thrust applied by the spring 9-4, so that the moving block 9-3 can drive the reinforcing sleeve 9-1 to move through the connecting block 9-2, so that the reinforcing sleeves 9-1 at both ends of the flipping rod 7 are respectively fitted onto the fixed post 6 and the connecting rod 8. At this time, the flipping rod 7, the fixed post 6 and the connecting rod 8 can form a support component for the net body 2, preventing the net body 2 from swinging significantly. Then, the anchor nail 5 is fixed at the river bottom or other positions to fix the position of the net cage.

[0033] When the cage needs to be stored, the reinforcing sleeves 9-1 at both ends of the flipping rod 7 can be moved in opposite directions, so that the two reinforcing sleeves 9-1 are detached from the fixed post 6 and the flipping rod 7 respectively. At this time, the spring 9-4 is compressed by the moving block 9-3. Then the flipping rod 7 can be flipped to a horizontal state, and the reinforcing sleeves 9-1 can be released, so that the spring 9-4 returns to its original position and pushes the moving block 9-3. The moving block 9-3 drives the reinforcing sleeves 9-1 to move through the connecting block 9-2, so that one end of the reinforcing sleeve 9-1 is inserted into the limiting groove 13, realizing the limiting of the flipping rod 7 in this state. At this time, the cage will be flat, making it easier to store.

[0034] Compared with the prior art, the beneficial effects of this utility model are:

[0035] The three-dimensional support assembly consisting of fixed column 6, flipping rod 7, connecting rod 8 and positioning and reinforcement mechanism 9 forms a rigid reinforcement frame around the net body 2. When the net cage is impacted by wind and waves, the support assembly can effectively constrain the swing amplitude of the net body 2, disperse wave load, and avoid tearing caused by local stress concentration in the net body 2.

[0036] By using the sealing ring 12, the sealing performance of the gap between the reinforcing sleeve 9-1 and the flipping rod 7 can be improved, preventing water from seeping into the interior of the flipping rod 7 and causing corrosion of the spring 9-4.

[0037] When the reinforcing sleeve 9-1 and the flipping rod 7 are flipped to the horizontal state, the reinforcing sleeve 9-1 and the limiting groove 13 cooperate, and the spring 9-4 applies a pushing force to the moving block 9-3, so that the reinforcing sleeve 9-1 and the flipping rod 7 can be limited in this state, thus facilitating the storage of the cage.

[0038] The reinforcing ring 16 not only enhances the overall rigidity of the floating frame 1, but its reflective strips 17 on the outer wall can also provide active identification at night or in low visibility to avoid accidental collisions between ships.

[0039] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
