Description

Technical Field

[0001] This utility model belongs to the technical field of factory-style aquaculture equipment, and specifically relates to a pearl mussel seedling breeding device. Background Technology

[0002] Pearl mussel seedlings are the young oysters used for pearl farming. The selection and quality of these seedlings have a significant impact on the final quality and yield of the pearls.

[0003] The selection of seedlings is usually based on the following factors:

[0004] 1. Varieties: There are many varieties of pearl mussels, including Japanese pearl mussels and Chinese pearl mussels. Different varieties of pearl mussels may differ in growth rate, pearl quality, and other aspects.

[0005] 2. Age: The age of seedlings is usually calculated in months. Generally speaking, the older the seedling, the faster it grows, but the quality of the pearl may be affected.

[0006] 3. Health Condition: Selecting healthy seedlings is very important, as they are more likely to grow high-quality pearls. The seedlings should be free of obvious diseases or damage.

[0007] 4. Size: The size of the seedlings is also a factor to consider. Generally speaking, larger seedlings may have higher growth potential, but they also require more breeding resources.

[0008] Most existing pearl mussel seedlings are propagated in open-air environments, lacking control measures and relying on the weather, resulting in low survival rates and small-scale farming. Improving the controllability of pearl mussel seedling propagation is a research topic for those skilled in the art. Utility Model Content

[0009] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a pearl mussel seedling breeding device that allows for controlled growth environment, large single-culture volume, and high survival rate in industrialized aquaculture.

[0010] To achieve the above objectives, this invention provides a pearl mussel seedling breeding device, comprising a culture tray for breeding pearl mussel seedlings and a control box for the culture water environment. The control box is equipped with a heat exchanger, a return water pipe, and an outlet water pipe. The culture water flowing out of the outlet pipe connects to two or more culture trays. The culture water in the culture trays flows back to the control box through the return water pipe. Each culture tray is equipped with a rotating sprinkler and a lifting device to control the raising and lowering of the rotating sprinkler. The lifting device allows the pearl mussel seedlings to breed not only underwater but also above the water surface under sunlight during the breeding period. This pearl mussel seedling breeding device controls the temperature of the culture water environment through the heat exchanger and allows the addition of various nutrients to control the growth of the pearl mussel seedlings. The return water pipe and outlet water pipe, together with the culture tray, enable the recycling of the culture water. The rotating sprinkler and the lifting device dynamically control the water depth for the pearl mussel seedlings, thus allowing the pearl mussel seedlings to breed not only underwater but also above the water surface under sunlight during the breeding period. Sunlight helps eliminate harmful bacteria and improves the survival rate of the bred seedlings.

[0011] The rotating sprinkler device includes a first motor connected to a drive pulley, which is connected to a driven pulley via a belt. The driven pulley drives a vertical water pipe to rotate. The vertical water pipe is connected to two or more horizontal spray pipes arranged vertically. The spray positions of the horizontal spray pipes correspond to the relative positions of the aquaculture trays. The horizontal spray pipes have spray holes. The aquaculture water sprayed from the spray holes can not only moisten the pearl mussel seedlings and control the water depth, but also achieve a water flow effect to increase the oxygen content in the aquaculture environment.

[0012] The vertical water pipe is divided into multiple sections connected by connecting pipes. Each section of the vertical water pipe passes through a water-blocking pipe in the middle of a breeding tray. The water-blocking pipe is connected to the return water pipe with a return water connector, so that the water volume and water depth of each breeding tray are controlled synchronously to achieve the technical purpose of large-scale breeding.

[0013] The return water pipe is connected to two or more horizontal connecting pipes. One end of each horizontal connecting pipe is connected to the connecting pipe, and the side of the horizontal connecting pipe is connected to the return water hole opened on the bottom of the breeding tray through a branch pipe, so as to realize the technical performance of centralized return water.

[0014] The water outlet pipe is connected to the first interface of the branch pipe via a flexible hose. The other interface of the branch pipe is movably connected to the vertical water pipe. The branch pipe structure enables water to enter the water outlet pipe without interfering with the rotation of the water outlet pipe. In other words, the branch pipe remains relatively stationary while the water outlet pipe rotates. This function can generally be achieved by using a connecting ring or a connecting bearing.

[0015] A water pump with a venturi tube is provided between the water outlet pipe and the hose to provide water pressure for the water outlet pipe.

[0016] The two or more breeding trays are matched with triangular supports of corresponding layers to support the breeding trays and increase the breeding volume per unit area.

[0017] The horizontal water spray pipe has an n-shaped structure on both sides of the vertical water pipe, with the top higher than the bottom. The n-shaped structure is reinforced by the connection of the two sides with rings, and the n-shaped structure creates a height difference, which increases the water pressure of the horizontal water spray pipe.

[0018] The lifting device for controlling the raising and lowering of the rotary sprinkler includes a mounting base connected to a first motor. The mounting base is also connected to a lifting motor, a guide column, and a branch pipe. The lifting motor drives a lifting screw, which moves up and down. The lifting screw and the guide column are connected to a lifting base. Since the guide column is fixedly connected to the return water connector through a connecting piece, the guide column and the lifting screw are fixed in place. Instead, the lifting motor drives the entire rotary sprinkler to move up and down, improving the water level control for pearl mussel seedlings.

[0019] The beneficial effects of the present invention by adopting the above technical solution are as follows:

[0020] The temperature of the aquaculture water is controlled by a heat exchanger, and various nutrients can be added to control the growth of pearl mussel seedlings. The return water pipe and the outlet water pipe work together with the aquaculture tray to realize the recycling of the aquaculture water. The rotating sprinkler and the lifting device that controls the raising and lowering of the rotating sprinkler realize the dynamic control of the water depth for pearl mussel seedling cultivation. Thus, during the breeding period, pearl mussel seedlings can not only reproduce underwater, but also reproduce above the water surface under light. The light eliminates harmful bacteria and improves the survival rate of reproduction. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0029] like Figure 1-6 As shown, a pearl mussel seedling breeding device includes a breeding tray 7 for breeding pearl mussels and a control box 2 for the breeding water environment. The control box 2 is equipped with a heat exchanger 1, a return water pipe 3, and an outlet water pipe 10. The breeding water flowing out of the outlet water pipe 10 is connected to two or more breeding trays 7. The breeding water in the breeding trays 7 flows back to the control box 2 through the return water pipe 3. Each breeding tray 7 is equipped with a rotating sprinkler device and a lifting device for controlling the raising and lowering of the rotating sprinkler device.

[0030] The preferred rotary sprinkler system includes a first motor 20 connected to a drive pulley 19, which in turn is connected to a driven pulley 28 via a belt 29. The driven pulley 28 drives a vertical water pipe 16 to rotate. The vertical water pipe 16 is connected to two or more horizontal spray pipes 6 arranged vertically. The spray positions of the horizontal spray pipes 6 correspond to the relative positions of the aquaculture trays 7, and each horizontal spray pipe 6 has spray holes. The rotation of the vertical water pipe 16 drives the rotation of the horizontal spray pipes 6, achieving the technical purpose of rotary spraying. This replenishes the aquaculture water and provides timely and even water replenishment to the pearl mussels under sunlight. The horizontal spray pipes 6 have an n-shaped structure on both sides of the vertical water pipe 16, with the top higher than the bottom. The n-shaped structure is reinforced by connecting the two sides with rings 17, creating a height difference and increasing the water pressure at the outlet of the horizontal spray pipes.

[0031] The vertical water pipe 16 is divided into multiple sections connected by connecting pipes 32. Each section of the vertical water pipe 16 passes through a water-blocking pipe 12 in the middle of a breeding tray 7. The water-blocking pipe 12, in conjunction with the return water connector 41, connects to the return water pipe 3 to achieve the technical purpose of factory-style layered control of breeding quantity. The return water pipe 3 connects to two or more horizontal connecting pipes 4. One end of each horizontal connecting pipe 4 is connected to the connecting pipe 32, and the side of the horizontal connecting pipe 4 is connected to the return water hole 11 opened on the bottom surface of the breeding tray 7 through a branch pipe 13. Ultimately, the effect of recycling breeding water is achieved, avoiding wastewater discharge and possessing the function of green breeding.

[0032] As a preferred structural design, the outlet pipe 10 is connected to the first port 26 of the branch pipe 27 via a flexible hose 15. The other port of the branch pipe 27 is movably connected to the vertical water pipe 16, thereby allowing the vertical water pipe 16 to rotate and move up and down to supply water without interfering with the outlet pipe 10 connected to the branch pipe 27. A water pump 9 with a venturi tube 8 is provided between the outlet pipe 10 and the flexible hose 15, which increases the water supply capacity of the pump while reducing energy consumption.

[0033] In order to increase the total number of animals raised per unit area, two or more breeding trays 7 are matched with triangular supports 5 of corresponding layers. The shape of the triangular supports 5 is not limited to triangular stacking, but can also be other stacking structures.

[0034] To further control the water depth and spray angle for pearl mussel seedling cultivation, a lifting device controlling the raising and lowering of the rotary sprinkler includes a mounting base 25 connected to a first motor 20. The mounting base 25 also connects to a lifting motor 21, a guide column 24, and a branch pipe 27. The lifting motor 21 drives a lifting screw 22. The lifting screw 22 and the guide column 24 are connected to a lifting base 23. Because the guide column is fixedly connected to the return water connector via a connecting piece, the guide column and lifting screw remain stationary, while the lifting motor drives the entire rotary sprinkler to move up and down, improving the control over the water level in pearl mussel seedling cultivation.

[0035] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the invention. The scope of the present invention is defined by the appended claims and their equivalents.
