Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture three-dimensional aquaculture devices, specifically a rotating hanging box aquaculture device. Background Technology

[0002] With the country's active promotion of facility-based fisheries development in recent years, land-based circular pond aquaculture has quietly emerged across the country. However, due to its limited suitable species and consistently high operating costs, the returns are highly unstable. To increase the variety of species cultured in land-based circular ponds, improve overall output and efficiency, and promote facility-based aquaculture production, people are developing three-dimensional aquaculture. Traditional three-dimensional aquaculture involves setting up net cages within the pond, forming a floating aquaculture device by binding floats to a square iron frame, or by using the pond walls to pull net cages for aquaculture in indoor ponds. However, traditional net cage aquaculture has its own shortcomings, such as: the net cages are soft and hang naturally in the water under gravity, making them susceptible to water flow impacts or deformation during migration, affecting the survival of the cultured organisms; climbing aquatic species are difficult to culture in net cages; the net cages rely on their own cables for support, and overloading can easily cause them to fall and result in losses; and it is not convenient for conducting small-scale separated aquaculture experiments. Therefore, there is a need to develop a rotating suspended cage aquaculture device that can be installed on land-based circular ponds. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a rotating cage culture device that can effectively improve the utilization space of land-based circular ponds for aquaculture, cultivate a variety of supporting aquatic animals, and improve the economic benefits of integrated aquaculture production. This rotating cage culture device has a cleverly designed structure that can effectively improve the utilization space of land-based circular ponds for aquaculture, cultivate a variety of supporting aquatic animals, improve the economic benefits of integrated aquaculture production, and also assist in conducting small-scale water body separation aquaculture experiments, facilitating feeding and observation, reducing experimental site and labor costs, and improving the convenience of experiments.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A rotating cage aquaculture device includes a large circular frame and a small circular frame rotatably mounted on the top of a land-based circular pond wall. The large circular frame is equipped with a sliding support for supporting the top surface of the land-based circular pond wall. The sliding support enables the entire device to rotate along the land-based circular pond wall. Multiple cage frames are evenly distributed and fixedly installed on the large circular frame. Each cage frame includes a square top frame for suspending a cage. The aquaculture cage is suspended inside the square top frame. A three-dimensional square frame is then installed inside the cage. The top of the three-dimensional square frame is positioned on the square top frame to support and position the aquaculture cage. A vertical rod is welded to each of the two bottom sides of one end of the square top frame. The bottom end of the vertical rod is fixedly connected to the large circular frame. The small circular frame connects the ends of the multiple cage frames furthest from the vertical rods. A diagonal brace connects the bottom end of the vertical rod to the small circular frame. The diagonal brace can also be configured to connect the large circular frame and the small circular frame.

[0006] A further preferred embodiment: the cross-section of the large circular frame is inverted U-shaped, and a set of sliding support members are installed at certain intervals in the groove formed at the bottom of the large circular frame. The sliding support members include wall pulleys and wall top pulleys, wherein the top of the groove is equipped with a wall top pulley that supports the top surface of the land-based circular pool wall, and the two inner sides are each equipped with a wall pulley that supports the two sides of the land-based circular pool wall.

[0007] A further preferred embodiment: the cross-section of the large circular frame is shaped like the number 7, and a set of sliding support components are installed at certain intervals inside the large circular frame. The sliding support components include a wall-top universal ball and a wall universal ball. The wall-top universal ball is supported on the top surface of the land-based circular pool wall, and the wall universal ball is supported on the inner side of the land-based circular pool wall.

[0008] A further preferred embodiment: the top surface of the square top frame is fitted with a cover frame via a hinge. The hinge includes a fixed hinge lug and a cover frame hinge lug. The fixed hinge lug is fixed to the square top frame or a small circular frame, and the cover frame hinge lug is fixed to the cover frame. The fixed hinge lug and the cover frame hinge lug are connected by a pin, allowing the cover frame to flip open from the square top frame, and a cover net can be laid on the cover frame. A hinged joint can also be used instead of a hinge.

[0009] A further preferred embodiment includes a latch on the cover frame that engages with the square top frame. The latch can also function as a handle to open the cover frame.

[0010] A further preferred embodiment: the cover frame is divided into two sections, and the two sections are connected by a hinge, which allows the cover frames to be folded together in a semi-open state.

[0011] This rotating cage aquaculture device features an ingenious structure. Through the combined design of a large circular frame, a small circular frame, sliding supports, and a cage frame, it can rotate along the wall of a land-based circular pond. Net cages are suspended inside the cage frame, enabling three-dimensional aquaculture in land-based circular ponds. This effectively increases the utilization space of the water body in the land-based circular pond, allowing for the cultivation of various aquatic animals and improving the economic benefits of integrated aquaculture production. It can also assist in conducting small-scale water body separation aquaculture experiments, facilitating feeding and observation, reducing experimental site and labor costs, and improving the convenience of experiments.
