[0002] Pinctada maxima, also known as the white lipped oyster, is an ideal pearl oyster for cultivating high-quality "South Sea pearls." Its production of South Sea pearls accounts for 46% of the total value of marine cultured pearls, making it a dominant player in pearl production. Pinctada maxima is the largest of all marine pearl oysters, and its cultivated pearls are large, lustrous, and have thick nacre. These pearls are considered rare and highly commercially valuable. Pinctada maxima is typically cultivated using cages with suspended ropes and bottom seeding. However, currently, when Pinctada maxima is submerged in water for hanging culture, there is a lack of a stable limiting structure, which causes the hanging culture box to easily rock in the water with the fluctuation of the water flow. In stormy weather, the seabed water fluctuates greatly, and the rocking amplitude of the hanging culture box is large, which does not utilize the growth of Pinctada maxima, resulting in an increase in the pearl oyster's nucleus expulsion rate and a decrease in the overall pearl production. Therefore, the present invention provides a Pinctada maxima island reef value-added device and a culture method thereof to improve the yield and quality of pearl culture. Summary of the Invention

Light control: The driving motor can be used to drive the winding rod to rotate and move along the guide groove to reel in and unfold the shading strip, so that the top of the hanging box is covered and directly exposed to achieve the operation of controlling light.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. A high-security hanging mechanism is provided. The positioning frame is used to limit the hanging crossbar, making the hanging and installation of the hanging box more convenient and quick. A certain distance is maintained between each other. The L-shaped positioning long rod is used to limit the corners of the hanging box, which improves the hanging stability of the hanging box and prevents the hanging box from shaking with the water flow, affecting the normal attachment and growth of the Pinctada maxima oyster. By stabilizing the growth environment of the Pinctada maxima oyster, it plays a role in promoting growth and thus improving pearl production. At the same time, the connecting sleeve and the positioning stud cooperate with each other to determine the position of the pressing disc, so that the pressing disc can be tightly pressed on the top of the L-shaped positioning long rod, pressing and stabilizing the position of the protective block, thereby improving the stability of the L-shaped positioning long rod and preventing the protective block and the L-shaped positioning long rod from shaking and falling off in strong winds and huge waves.

[0015] 2. Two protective nets and two protective side nets are used to surround the outer side of the hanging culture box, which plays a role in isolating and protecting the hanging culture box, preventing fish and other harmful organisms in the water from harming the Pinctada maxima oysters. This improves the safety of the overall growth and cultivation environment of the Pinctada maxima oysters, reduces the chance of being eaten, and increases the overall pearl production. At the same time, the counterweight box is used to counterweight the protective net, causing it to expand downward and reduce the impact of water flow on the protective net, while the supporting long board has the effect of stretching the protective side net, so that the protective side net remains flat and expanded. The locking studs and the mounting blocks cooperate with each other to determine the position of the clamping long rod, so that the bottom of the clamping long rod presses the supporting long board, which plays a role in positioning and stabilizing the supporting long board. Therefore, the protective net and the protective side net are both subject to certain limited support, so that they always remain in the expanded state to protect the hanging box, and prevent the protective net and the protective side net from deformation caused by water flow fluctuations and affecting the normal protection range.

[0016] 3. The bottom of the counterweight box is sealed and protected by a movable plate, so that the counterweight stones can remain inside the counterweight box, which plays a role in normal counterweight stability. The position of the movable plate can be adjusted by using a control rope, providing enough space for the counterweight stones inside the counterweight box to fall, thereby reducing the weight at the bottom of the protective net, greatly improving the convenience for the staff to lift the protective net, and preventing the counterweight stones from being too heavy and causing excessive work intensity when lifting. The operation is extremely simple.

[0017] 4. A shading automation control mechanism is provided, which uses the cooperation of the driving gear and the fixed long rack to drive the winding rod, and the guide groove limits and guides the guide block and the driving motor, so that the driving motor can drive the winding rod to rotate, and the driving motor can move along the guide groove, and then the winding rod and the series rope can be used to reel in and lengthen the shading strip, which provides great convenience for controlling the shading and releasing the light. The use of automatic control drive instead of manual laying effectively improves the work efficiency of the shading construction.

[0018] 5. The photovoltaic panels are exposed to the outside to absorb sunlight and convert it into electrical energy, which is stored inside the battery pack for use as energy for the drive motor. There is no need to connect to the external power supply line, which improves resource utilization and reduces the workload caused by external line connection. It prevents the complex entanglement of environmental lines caused by line connection, and the wiring trough guides the connected lines, providing sufficient space for the direction of the lines when the drive motor moves, making it safer and more convenient to use.

[0019] In summary, through the combination of a high-security hanging culture mechanism and a shading automatic control mechanism, the protective net and protective side nets surround the outside of the hanging culture box, providing sufficient safety space for the production of Pinctada maxima and creating favorable conditions for the value-added of pearl production. At the same time, the shading strips also optimize the growth environment of Pinctada maxima and reduce the adverse effects of sunlight on it. The control operation is simple and can be frequently adjusted according to the requirements of sunlight and growth environment. Both of them improve the growth environment of Pinctada maxima and promote the growth of pearls from multiple aspects to achieve the effect of value-added. BRIEF DESCRIPTION OF THE DRAWINGS

Before sinking, some counterweight stones were put into the counterweight box 417 and piled on the top of the movable plate 419, which played a role in stabilizing the counterweight of the protective net 409. The bottom of the protective side net 410 was fixedly connected to the The supporting long board 411 is connected. When it is sunk into the water, the clamping long rod 415 is used to penetrate the middle of the mounting block 413. The locking stud 414 is rotated and fixedly connected to the mounting block 413. The bottom end of the clamping long rod 415 is inserted into the middle of the supporting long board 411, which plays a role in firmly positioning the supporting long board 411, thereby improving the stability of the protective side net 410, thereby improving the safety of the outside of the hanging culture box 403, isolating the fish harmful to the giant pearl oyster in the water, and reducing the loss during the culture of the giant pearl oyster. At the same time, the connecting column 421 at the top of the movable board 419 will be connected to the bottom end of the control rope 422, and the top of the control rope 422 is fixed to the fixed round rod 416; In the process of growing and producing pearls, it is extremely important to control the light. When the light is too strong, the pearl oyster needs to be shielded from light. The driving motor 508 is controlled to start, so that it drives the winding long rod 509 and the driving gear 510 to rotate. The driving gear 510 will engage with the fixed long rack 504, and play a role of limiting and guiding the driving motor 508. While driving the winding long rod 509 to rotate, it moves forward along the guide groove 505, and unfolds the shading strip 501 wrapped around the surface of the winding long rod 509 to cover the left floating installation surface. Between the plate 2 and the right mounting float 3, the light on the top of the hanging culture box 403 is shielded, which plays a protective role for the Pinctada maxima oyster. At the same time, the Pinctada maxima oyster also needs a certain amount of light for growth. The driving motor 508 is regularly controlled to drive the winding long rod 509 to rotate and move forward along the guide groove 505 to reel in the unfolded light-shielding strip 501. The appropriate amount of light can promote the formation and growth of pearls. The control method is extremely simple, and the photovoltaic panel 514 and the battery pack 512 can absorb sunlight and convert and store energy for use by the driving motor 508. When harvesting pearls, the protective net 409 and the protective side net 410 also need to be scooped up and maintained. The counterweight stones inside the counterweight box 417 make the overall weight of the protective net 409 heavier and difficult to scoop up. The staff can hold the control rope 422 and pull it upward, and use the connecting column 421 to pull one end of the movable plate 419 to move upward. The guide cylinder 420 and the guide frame 418 cooperate with each other to make one end of the movable plate 419 move upward and tilt, and the other end gradually approaches the middle, creating a certain gap between the movable plate 419 and the bottom of the counterweight box 417. When the movable plate 419 moves, the counterweight stones on its top will be dumped, causing it to sink into the water, thereby reducing the overall weight of the protective net 409 and reducing the overall labor intensity of the scooping net.
