A type of nearshore suspended net aquaculture rack

Abstract

This invention provides a nearshore suspended net aquaculture rack, comprising a main body and a double-layered platform. The platform consists of an upper platform made of rectangular plates and a lower platform made of three strip-shaped plates. The upper and lower platforms are connected to form a trapezoidal platform structure. The upper platform is located above sea level, while the lower platform is flush with the sea level. A rectangular float is fitted onto each strip-shaped plate, and the floats are arranged diagonally along the lower platform. A net cage is suspended below each float. The upper and lower platforms are connected by inclined and vertical rods. The inclined rods are arranged on both sides of the platform, and anchor chains and spherical floats are fixed at the connection points between the inclined rods and the lower platform. This invention increases the attachment area for shellfish by adding net cages below the aquaculture rack, and the depth of the net cages can be precisely matched to the different shellfish's requirements for water temperature and salinity by adjusting the depth of the net cages.

Description

Technical Field

[0001] This utility model relates to the fields of marine biological resource survey, seaweed farms, and fishery resource protection technology, specifically a nearshore suspended net aquaculture rack. Background Technology

[0002] Nearshore aquaculture racks are modular aquaculture facilities suitable for shallow sea or nearshore waters. They combine ecological aquaculture concepts with automation technology and are mainly used for the efficient cultivation of aquatic products such as shellfish and fish. However, existing aquaculture racks have a simple structure and cannot make good use of and plan the area below the rack. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a nearshore suspended net aquaculture rack to solve at least one of the above-mentioned technical problems.

[0004] The technical solution of this utility model is: a nearshore suspended net aquaculture rack, including an aquaculture rack body, characterized in that the aquaculture rack body includes a double-layer platform, the platform includes an upper platform made of rectangular plates and a lower platform made of three strip plates, the upper platform and the lower platform are connected to form a trapezoidal platform, the upper platform is located above the sea level, and the lower platform is in contact with the sea level;

[0005] Each strip plate is fitted with a rectangular float, and the installation positions of the rectangular floats are arranged along the diagonal of the lower platform. A breeding net cage is suspended below each rectangular float.

[0006] The upper platform and the lower platform are connected by inclined rods and vertical rods. The inclined rods are arranged on both sides of the platform, and the connection between the inclined rods and the lower platform is fixed with a fixed anchor chain and a spherical float.

[0007] This invention increases the attachment area for shellfish by adding net cages below the aquaculture racks. The depth of the net cages can be precisely matched to the different shellfish's requirements for water temperature and salinity. Furthermore, the optimized arrangement of the net cages makes the entire platform more stable and less susceptible to wave impact. The addition of floats and anchor chains to the lower platform further ensures the platform's stability.

[0008] In a further preferred embodiment, the vertical rod divides each strip plate into three regions, and the rectangular float moves along each region.

[0009] This invention features a movable rectangular float that maintains the stability of the lower platform.

[0010] In a further preferred embodiment, the aquaculture cage is fixed below the rectangular float by a metal rope, and the metal rope is connected to the strip-shaped plate.

[0011] The cage can be raised and lowered by adjusting the length of the metal rope.

[0012] Further preferably, the aquaculture cage is a cylindrical cage with an opening at the top, a diameter of 1.5m, and a height of 1m.

[0013] This invention optimizes the structure of the net cage, which not only increases the attachment area for shellfish but also helps them resist wind and waves.

[0014] Preferably, the thickness of the rectangular plate is greater than the thickness of the strip plate, and both the rectangular plate and the strip plate are made of fiberglass.

[0015] This invention utilizes fiberglass material to ensure that sunlight below sea level is not affected. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0017] In the diagram: 1. Upper platform; 2. Lower platform; 3. Rectangular float; 4. Aquaculture cage; 5. Inclined rod; 6. Vertical rod; 7. Fixed anchor chain; 8. Spherical float; 9. Metal rope. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Reference Figure 1 As shown, a nearshore suspended net aquaculture rack includes a main body of the aquaculture rack, which includes a double-layer platform. The platform includes an upper platform 1 made of rectangular plates and a lower platform 2 made of three strip plates. The upper and lower platforms are connected to form a trapezoidal platform structure. The upper platform is located above the sea level, and the lower platform is close to the sea level. A rectangular float 3 is fitted on each strip plate, and the installation positions of the rectangular floats are arranged along the diagonal of the lower platform. An aquaculture net cage 4 is suspended below each rectangular float. The upper and lower platforms are connected by inclined rods 5 and vertical rods 6. The inclined rods are arranged on both sides of the platform, and the connection between the inclined rods and the lower platform is fixed with a fixed anchor chain 7 and a spherical float 8.

[0020] This invention increases the attachment area for shellfish by adding net cages below the aquaculture racks. The depth of the net cages can be precisely matched to the different shellfish's requirements for water temperature and salinity. Furthermore, the optimized arrangement of the net cages makes the entire platform more stable and less susceptible to wave impact. The addition of floats and anchor chains to the lower platform further ensures the platform's stability.

[0021] In a further optimized design, the vertical rod divides each strip-shaped plate into three regions, and the rectangular float moves along each region. This invention allows the rectangular float to move while maintaining the stability of the lower platform.

[0022] In a further optimized design, the aquaculture cage is fixed below the rectangular float by a metal rope 9, and the metal rope is connected to the strip-shaped plate. The cage can be raised and lowered by adjusting the length of the metal rope.

[0023] Further optimized, the aquaculture cage is a cylindrical structure with an opening at the top. The cage has a diameter of 1.5m and a height of 1m. This invention, by optimizing the cage structure, not only increases the attachment area for shellfish but also helps them withstand wind and waves.

[0024] Further optimized, the thickness of the rectangular plate is greater than the thickness of the strip plate, and both the rectangular and strip plates are made of fiberglass. This invention, by using fiberglass, does not affect sunlight exposure below sea level.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
