Description

Technical Field

[0001] This utility model belongs to the field of goldfish farming technology, specifically a net cage for pond goldfish farming. Background Technology

[0002] Cage aquaculture originated in Southeast Asian countries such as Cambodia in the late 19th century and later spread to other parts of the world. Freshwater cage aquaculture in my country began in the 1970s and has developed rapidly in recent years. Cage fish farming is now practiced in almost all large, medium, and small lakes and reservoirs, and even in some slow-flowing rivers and ponds. For example, Chinese utility model patent CN 213819414 U discloses a cage for pond rearing of fish fry. However, this cage is not suitable for raising goldfish in ponds. Due to the lack of a good oxygen supply system, it may cause water quality deterioration and oxygen deficiency, leading to health problems for goldfish. Furthermore, the cage does not consider how to prevent goldfish from escaping or the entry of predators.

[0003] Therefore, how to provide a net cage for pond-cultured goldfish that can continuously replenish oxygen and purify water quality has become a problem that needs to be considered by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a net cage for pond-raised goldfish. This invention, through the setting of a load-bearing oxygenation mechanism, can continuously filter water quality and replenish oxygen, keep the water clean, and provide a good growth environment for goldfish.

[0005] To achieve the above objectives, this utility model provides a net cage for pond goldfish farming, comprising a frame, a net, a net cover, and a weight-bearing aeration mechanism. The frame is constructed from PVC pipes and has a rectangular structure. The net is placed on the surface of the frame to form the net cage. The net cover is installed on the top of the net cage. A hanging ring is provided at the top corner of the net cage. An air inlet pipe is installed inside the PVC pipe, with its opening extending from the bottom of a vertical PVC pipe. The two ends of the weight-bearing aeration mechanism are attached to the air inlet pipe via pipe clamps. The weight-bearing aeration mechanism is fixed to the top of the PVC pipe at the bottom of the frame by figure-eight buckles.

[0006] Furthermore, the load-bearing oxygenation mechanism includes an aeration tube, a solid rubber rod, and a connecting joint. One side of the connecting joint is a pagoda-shaped insertion end for connecting to the air inlet pipe. The other end of the connecting joint is provided with a first insertion groove, in which a hollow support is provided. The center of the hollow support is provided with a second insertion groove concentric with the first insertion groove. Both ends of the solid rubber rod are respectively inserted into the second insertion groove, and both ends of the aeration tube are respectively inserted into the first insertion groove and sealed with waterproof glue.

[0007] Furthermore, it also includes buoyancy balls, which are inserted into the vertical PVC pipes of the cage.

[0008] Furthermore, it also includes traction ropes, which are respectively set on two diagonally opposite hanging rings at the top of the cage.

[0009] Furthermore, the edge of the mesh cover is provided with a semi-circular buckle for attaching to the PVC pipe at the top of the mesh cage.

[0010] Furthermore, the mesh is woven from polyethylene nylon rope, and the mesh count of the mesh is 48 to 60.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model has a simple structure. Through the setting of the load-bearing oxygenation mechanism, it can continuously improve water quality and keep the water clean while also acting as a sinker, providing a good growth environment for goldfish, meeting their respiratory needs, and preventing health problems caused by lack of oxygen. The setting of the hanging ring allows the net cage to be suspended in the pond by threading steel wire ropes through it. The net cover can be quickly installed and removed by the semi-circular buckle, which not only prevents the entry of predatory organisms, but also prevents goldfish from jumping out of the net cage.

[0021] Example 1

[0022] like Figure 1-4 As shown in the figure, this embodiment discloses a net cage for pond goldfish farming, including a frame, a net 2, a net cover 3, and a load-bearing aeration mechanism.

[0023] The frame is constructed from PVC pipes 1 with an inner diameter of 50mm, forming a rectangular structure with dimensions (length × width × height) of 1m × 1m × 0.5m. A net 2 is placed over the frame to form a net cage. In this embodiment, the net 2 is woven from polyethylene nylon rope with a mesh count of 48, preventing goldfish from escaping and blocking predators from entering. The edge of the net cover 3 has semi-circular clips 9, which secure it to the PVC pipes 1 at the top of the net cage, ensuring quick installation and removal of the net cover 3. The net cover 3 prevents predators from entering the net cage and also prevents goldfish from jumping out.

[0024] Four lifting rings 4 are installed at the top corners of the net cage. Two diagonally opposite lifting rings 4 at the top of the net cage are also equipped with traction ropes. The net cage is suspended from the wire connecting the two ends of the pond via the lifting rings 4, and can be moved by pulling the traction ropes as needed for aquaculture management. When the net cage is used in an indoor aquaculture pond, the lifting rings 4 can also be used to thread a hanging rod. By setting the hanging rod on the top of the aquaculture pond, the net cage can be suspended and placed in the pond.

[0025] In this embodiment, an air inlet pipe is installed inside the PVC pipe 1. The air inlet end of the air inlet pipe is connected to the Roots blower. The inlet of the air inlet pipe extends from the bottom of the vertical PVC pipe 1. Both ends of the load-bearing oxygenation mechanism are mounted on the air inlet pipe via pipe clamps. The load-bearing oxygenation mechanism is fixed to the top of the PVC pipe 1 at the bottom of the frame via figure-eight buckles 5. The load-bearing oxygenation mechanism includes an aeration and oxygenation pipe 6, a solid rubber rod 7, and a connecting joint 8. One side of the connecting joint 8 is a pagoda-style insertion end for connecting the air inlet pipe. The other end of the connecting joint 8 is provided with a first insertion groove. A hollow support is provided in the first insertion groove. A second insertion groove concentric with the first insertion groove is provided in the center of the hollow support. Both ends of the solid rubber rod 7 are respectively inserted into the second insertion groove, and both ends of the aeration and oxygenation pipe 6 are respectively inserted into the first insertion groove and sealed with waterproof glue.

[0026] The solid rubber rod 7 is mainly used as a sinker to increase the settling speed of the net cage and the pressure of the bottom edge of the net cage on the water bottom. It also serves to support and shape the aeration pipe 6 so that it can be evenly laid on the bottom of the net cage. When compressed air enters the connecting joint from the air inlet pipe, the air can pass through the hollow support and enter the gap between the solid rubber rod 7 and the aeration pipe 6, and finally diffuse into the pool water through the aeration holes of the aeration pipe 6.

[0027] Example 2

[0028] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that this embodiment also includes a buoyancy ball 10. The buoyancy ball 10 is inserted into the vertical PVC pipe 1 of the net cage. With the setting of the buoyancy ball 10, it is not necessary to set up steel wire ropes in the pond to ensure that the net cage floats in the pond.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
