Description

Technical Field

[0001] This utility model relates to the field of cage aquaculture technology, and more specifically, to a marine triangular current-blocking cage. Background Technology

[0002] Deep-sea wave-resistant cages have been widely used as important equipment in my country's deep-sea aquaculture industry. However, based on current usage, traditional square or circular cages have the following shortcomings in strong ocean current environments:

[0003] (1) The eddy current effect of seawater causes the netting to deform and the aquaculture space to be compressed;

[0004] (2) Stress concentration on the upstream surface leads to damage to the gabion structure.

[0005] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a marine triangular current-blocking net box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A marine triangular current-blocking cage includes a first buoyancy pipe, a second buoyancy pipe, and a third buoyancy pipe. The first buoyancy pipe, the second buoyancy pipe, and the third buoyancy pipe are connected end to end to form a triangular structure. A reinforcing pipe is provided in the area enclosed by the first buoyancy pipe, the second buoyancy pipe, and the third buoyancy pipe. The first buoyancy pipe, the second buoyancy pipe, and the third buoyancy pipe are connected to each other through the reinforcing pipe.

[0009] Furthermore, the first and second buoyancy tubes are of equal length and are connected to the third buoyancy tube to form an isosceles triangle structure.

[0010] Furthermore, the first buoyancy tube is connected to one end of the third buoyancy tube via a drain pipe, and the second buoyancy tube is connected to the other end of the third buoyancy tube via a drain pipe, wherein the drain pipe is arranged perpendicular to the third buoyancy tube.

[0011] Furthermore, the drainage tube includes an inner drainage tube and an outer drainage tube, which are connected by multiple connecting sleeves.

[0012] Furthermore, the first buoyancy tube and the reinforcing tube, the second buoyancy tube and the reinforcing tube, the third buoyancy tube and the reinforcing tube, and the reinforcing tubes are connected by a joint assembly.

[0013] Furthermore, the connector assembly includes one or more of the following: a tee connector, a four-way connector, an arc connector, and a V-shaped connector.

[0014] Furthermore, the first buoyancy tube, the second buoyancy tube, and the third buoyancy tube each include an inner buoyancy tube and an outer buoyancy tube, and the inner buoyancy tube and the outer buoyancy tube are connected by multiple connecting sleeves.

[0015] Furthermore, the reinforcing pipe includes a first reinforcing pipe and a second reinforcing pipe, and the first reinforcing pipe and the second reinforcing pipe are connected by a plurality of connecting sleeves.

[0016] Furthermore, the first buoyancy pipe, the second buoyancy pipe, the third buoyancy pipe, and the reinforcing pipe are all made of HDPE.

[0017] The beneficial effects of this utility model are:

[0018] 1. In this utility model, the triangular structure formed by the combination of the first buoyancy tube, the second buoyancy tube, and the third buoyancy tube has good stability, improving the structural strength and current resistance of the cage. Simultaneously, by adding reinforcing tubes, which are arranged laterally and longitudinally, the stability of the triangular structure is further enhanced, thereby increasing the load-bearing capacity and wave resistance of the cage.

[0019] 2. In this utility model, by setting the apex of the triangle formed by connecting the first buoyancy tube and the second buoyancy tube towards the direction of seawater flow, the seawater flow is effectively diverted and the resistance of the net cage to the current is significantly reduced. At the same time, by using the inclined setting of the first buoyancy tube and the second buoyancy tube, the water flow is diffused to both sides and flows backward along the first buoyancy tube and the second buoyancy tube, which effectively reduces the pressure on the surface of the net cage facing the current.

[0020] 3. In this utility model, the overall structure of the cage is made of high-strength HDPE, which not only meets the strength to resist wind and waves, but also reduces manufacturing costs and subsequent maintenance expenses, ensuring that the overall structure of the cage has sufficient rigidity and durability.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: A marine triangular current-blocking cage, such as Figures 1-5 As shown, it includes a first buoyancy tube 1, a second buoyancy tube 2, and a third buoyancy tube 3. The first buoyancy tube 1, the second buoyancy tube 2, and the third buoyancy tube 3 have the same structure and are connected end to end to form a triangular structure. A reinforcing tube 4 is provided in the area enclosed by the first buoyancy tube 1, the second buoyancy tube 2, and the third buoyancy tube 3. The first buoyancy tube 1, the second buoyancy tube 2, and the third buoyancy tube 3 are connected through the reinforcing tube 4.

[0029] When in use, the net cage is placed in seawater, and the apex of the triangle formed by connecting the first buoyancy tube 1 and the second buoyancy tube 2 faces the direction of seawater flow. Under the buoyancy of the first buoyancy tube 1, the second buoyancy tube 2 and the third buoyancy tube 3, the net cage floats in the seawater.

[0030] By setting the apex of the triangle formed by connecting the first buoyancy pipe 1 and the second buoyancy pipe 2 towards the direction of seawater flow, seawater flow can be effectively diverted, significantly reducing the resistance of the net cage to the current. The inclined arrangement of the first and second buoyancy pipes 1 and 2 allows the water flow to diffuse to both sides and flow backward along the first and second buoyancy pipes 1 and 2, effectively reducing the pressure on the surface of the net cage facing the current. Furthermore, the triangular structure formed by the combination of the first buoyancy pipe 1, the second buoyancy pipe 2, and the third buoyancy pipe 3 has good stability, improving the structural strength and current resistance of the net cage. Simultaneously, by adding reinforcing pipes 4, which are arranged laterally and longitudinally, the stability of the triangular structure is further enhanced, thereby increasing the load-bearing capacity and wave resistance of the net cage.

[0031] Furthermore, the first buoyancy tube 1 and the second buoyancy tube 2 are of equal length and are connected to the third buoyancy tube 3 to form an isosceles triangle structure. Because the first buoyancy tube 1 and the second buoyancy tube 2 are of equal length, they provide better support and stability, allowing the cage to better resist deformation; at the same time, the isosceles triangle has axial symmetry, which reduces the formation of eddies.

[0032] Furthermore, such as Figure 1 and Figure 4 As shown, the first buoyancy tube 1 is connected to one side of the third buoyancy tube 3 through the drainage tube 5, and the second buoyancy tube 2 is connected to the other end of the third buoyancy tube 3 through the drainage tube 5. The drainage tube 5 is set perpendicular to the third buoyancy tube 3.

[0033] By setting up the diversion pipe 5, on the one hand, it is easy to identify the apex of the triangle formed by the connection of the first buoyancy pipe 1 and the second buoyancy pipe 2, so that the apex can be set towards the direction of seawater flow; on the other hand, the orientation of the diversion pipe 5 is the same as the direction of seawater flow, which plays a guiding role, changing the flow direction of the diversion water flowing along the first buoyancy pipe 1 and the second buoyancy pipe 2 from inclined to longitudinal, smoothly converging into the main water flow, reducing the formation of eddies, and ensuring that the internal environment of the cage remains stable.

[0034] Furthermore, the first buoyancy tube 1 and the reinforcing tube 4, the second buoyancy tube 2 and the reinforcing tube 4, the third buoyancy tube 3 and the reinforcing tube 4, and the reinforcing tube 4 and the reinforcing tube 4 are connected by a connector assembly 6. The connector assembly 6 includes one or more of a tee connector 61, a four-way connector 62, an arc connector 63, and a V-shaped connector 64; the tee connector 61, the four-way connector 62, the arc connector 63, and the V-shaped connector 64 are all sleeved on the buoyancy tube and the reinforcing tube 4 through connector through holes opened on them.

[0035] Specifically, such as Figure 2 As shown, at the connection between the first buoyancy tube 1 and the second buoyancy tube 2, an arc joint 63, a tee joint 61, and a four-way joint 62 are used to connect the first buoyancy tube 1 and the second buoyancy tube 2; as shown... Figure 3 As shown, at the connection between the reinforcing pipe 4 and the second buoyancy pipe 2, a tee connector 61, a four-way connector 62, and a V-shaped connector 64 are used to connect the reinforcing pipe 4 and the second buoyancy pipe 2; as shown... Figure 4 As shown, at the connection between the second buoyancy tube 2 and the drainage tube 5, a V-shaped connector 64 is used to connect the second buoyancy tube 2 and the drainage tube 5; as Figure 4 As shown, at the connection between the drainage tube 5 and the third buoyancy tube 3, an arc joint 63, a tee joint 61, and a four-way joint 62 are used to connect the drainage tube 5 and the third buoyancy tube 3; as shown Figure 5As shown, at the connection between the reinforcing tube and the third buoyancy tube 3, a tee connector 61 and a four-way connector 62 are used to connect the reinforcing tube 4 and the third buoyancy tube 3.

[0036] Furthermore, such as Figures 1-5 As shown, both the first buoyancy tube 1 and the second buoyancy tube 2 include an inner buoyancy tube 11 and an outer buoyancy tube 12. The inner buoyancy tube 11 and the outer buoyancy tube 12 are connected by multiple connecting sleeves 7, and the connecting sleeves 7 are fitted onto the inner buoyancy tube 11 and the outer buoyancy tube 12 through sleeve holes. The reinforcing tube 4 includes a first reinforcing tube 41 and a second reinforcing tube 42. The first reinforcing tube 41 and the second reinforcing tube 42 are connected by multiple connecting sleeves 7, and the connecting sleeves 7 are fitted onto the first reinforcing tube 41 and the second reinforcing tube 42 through sleeve holes. The drainage tube 5 includes an inner drainage tube 51 and an outer drainage tube 52. The inner drainage tube 51 and the outer drainage tube 52 are connected by multiple connecting sleeves 7, and the connecting sleeves 7 are fitted onto the inner drainage tube 51 and the outer drainage tube 52 through sleeve holes.

[0037] As a preferred option, the inner buoyancy pipe 11, outer buoyancy pipe 12, first reinforcing pipe 41, second reinforcing pipe 42, inner drainage pipe 51, outer drainage pipe 52, connecting pipe sleeve 7, and joint assembly 6 are all made of high-strength HDPE (high-density polyethylene) material, which not only meets the strength to resist wind and waves, but also reduces manufacturing costs and subsequent maintenance costs, ensuring that the overall structure of the cage has sufficient rigidity and durability.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
