Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology using floating bodies that float on seawater, and more specifically, to a wind and wave resistant aquaculture cage. Background Technology

[0002] In recent years, with the development of the social economy, marine aquaculture areas have gradually expanded from near-shore and shallow waters to deep seas, and various types of aquaculture cages have undergone upgrades, forming a relatively complete aquaculture cage system. However, the current functions of aquaculture cages are mostly limited to mobility functions such as resistance to wind and waves and adjustment with water levels. To better meet the safety, quality, and environmental protection requirements of marine aquaculture, improving the multifunctional features of aquaculture cages has become a trend.

[0003] Therefore, it is necessary to propose a wind and wave resistant aquaculture cage suitable for wastewater treatment with high sand content, high oil content, and high scum content. It is especially suitable for pretreatment aerated grit chambers and pretreatment dissolved air flotation chambers. It can improve the grit settling effect and the separation effect of oil and scum under limited aeration, which is of great significance to the energy consumption and operation effect of the system. Utility Model Content

[0004] This invention provides a wind and wave resistant aquaculture cage to solve the problem that it is difficult to achieve both aeration volume and sedimentation / separation effect in the existing aeration and sedimentation process.

[0005] According to one aspect of this utility model, a wind and wave resistant aquaculture cage is provided, comprising multiple floats and a cage, wherein the floats are spliced ​​together to form a frame structure, and the cage is installed on the frame structure; the floats have rectangular internal walls, including a bottom wall, side walls surrounding the bottom wall, and a cover, wherein the cover covers the top of the space surrounded by the bottom wall and side walls, the cover is made of high-density polyethylene, and multiple connectors for connecting the floats to each other are provided on the outer edge of the cover.

[0006] Preferably, based on the above scheme, the connector includes a first coupling body disposed on one pair of opposite sides and a second coupling body disposed on the other pair of opposite sides; the first coupling body includes an upper fastening portion with a fastening hole extending in a vertical direction, and a lower recess with a long groove extending in a vertical direction on both sides of the upper fastening portion; the second coupling body includes a lower fastening portion with a fastening hole extending in a vertical direction, and an upper recess with a long groove extending in a vertical direction on both sides of the lower fastening portion.

[0007] Based on the above scheme, the adjacent floats are spliced ​​together, with the upper fastening part of the float engaging with the upper concave part of the adjacent float, and the lower concave part of the float engaging with the lower fastening part of the adjacent float.

[0008] Based on the above scheme, preferably, the upper end surface of the cover is provided with a cross-shaped fixing groove, and the cross section of the fixing groove is U-shaped.

[0009] Based on the above scheme, preferably, a fixing rod is installed in the fixing groove, a locking cover is provided on the top of the fixing rod, and bolts that are inserted into the upper fastening part and the lower fastening part are installed at both ends of the locking cover.

[0010] Based on the above scheme, a preferred embodiment is that a variable buoyancy column is hung at the bottom of the float.

[0011] Based on the above scheme, a counterweight is also installed at the bottom of the float.

[0012] This utility model discloses a wind and wave resistant aquaculture cage, which adopts multiple floats spliced ​​together to form a frame structure. The cage can be assembled by installing it on the frame structure. The installation is convenient and quick, and it is easy to expand. At the same time, the bottom wall of the floats protrudes outward to form a streamlined shape with a central protrusion, which is not easily shaken by waves, thus achieving its purpose of resisting wind and waves.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, the present invention provides a wind and wave resistant aquaculture cage 2, which includes multiple floats 1 and cages 2. The floats 1 are spliced ​​together to form a frame structure 14, and the cages 2 are installed on the frame structure 14.

[0029] For a detailed explanation of the technical solution of this utility model, please refer to the following: Figure 2 As shown, the internal wall of the float 1 of this utility model is rectangular, including a bottom wall 11, a side wall 12 surrounding the bottom wall 11 and a cover 13. The cover 13 covers the top of the space surrounded by the bottom wall 11 and the side wall 12. The cover 13 is made of high-density polyethylene. Multiple connectors 15 for connecting the float 1 to each other are provided on the outer edge of the cover 13.

[0030] Specifically, the connector 15 of this utility model includes a first connector 16 disposed on one pair of opposite sides and a second connector 17 disposed on the other pair of opposite sides; the first connector 16 includes an upper fastening portion 161 with a fastening hole extending in the vertical direction, and a lower recess 162 with a long groove extending in the vertical direction on both sides of the upper fastening portion 161; the second connector 17 includes a lower fastening portion 171 with a fastening hole extending in the vertical direction, and an upper recess 172 with a long groove extending in the vertical direction on both sides of the lower fastening portion 171.

[0031] When adjacent floats 1 are connected to each other, they are spliced ​​together. The upper fastening part 161 of float 1 engages with the upper recess 172 of the adjacent float 1, and the lower recess 162 of float 1 engages with the lower fastening part 171 of the adjacent float 1. Fastening bolts 163 are inserted into the fastening holes to lock them in place, so that the adjacent floats 1 form an integral structure. It should be noted that the shape of the float 1 is selected according to actual needs, and a rectangular structure is preferred. These structural features make it robust and resistant to damage from wave vibration. Moreover, the rectangular structure of the float 1 can be selected to continuously combine n floats 1 to form a closed square according to actual needs, thus facilitating the construction or expansion of aquaculture farms.

[0032] The upper end face of the cover 13 of this utility model is provided with a cross-shaped fixing groove 181. The fixing groove 181 has a U-shaped cross section. A fixing rod 18 is installed in the fixing groove 181. A locking cover 182 is provided on the top of the fixing rod 18. Bolts 163 that are inserted into the upper fastening part 161 and the lower fastening part 171 are installed at both ends of the locking cover 182.

[0033] To secure multiple floats 1 arranged in a row, a fixing rod 18 is placed in a cross-shaped U-shaped fixing groove 181 and secured by a locking cap 182 and bolts 163. This ensures stability and prevents the floats from being easily rocked by waves.

[0034] Preferably, the present invention also has a variable buoyancy column 3 suspended at the bottom of the float 1, and a counterweight 4 is installed at the bottom of the variable buoyancy column 3.

[0035] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
