Description

Technical Field

[0001] The invention relates to the technical field of luminous pearl cultivation, and in particular to a method and equipment for cultivating luminous pearls. Background Art

[0002] Luminous pearls are usually produced by specific species of shellfish, and choosing the right shellfish species is crucial to successfully culturing luminous pearls. These shellfish species usually have special physiological characteristics and nacre secretion abilities that are suitable for producing luminous pearls. Light is an important factor in the pearl culturing environment. The right amount of light intensity can promote the growth of algae in the shells, which is beneficial to the metabolism of the shells and the formation of mother-of-pearl beads.

[0003] At present, in the traditional breeding method and equipment of luminous pearls, pearl oysters are usually placed directly in breeding boxes for breeding. In the limited breeding space, pearl oysters will compete for resources such as food, oxygen and light, resulting in growth restriction or malnutrition of some pearl oysters. In addition, pearl oysters block each other, and some pearl oysters will be in the shadow and unable to receive sufficient light, resulting in reduced photosynthesis efficiency of these pearl oysters, affecting their growth rate and health status. Uneven light on the surface of pearl oysters will cause uneven growth and irregular shape of pearl oysters, affecting the quality and yield of pearls, thereby resulting in poor practicality of breeding equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of poor practicability of pearl oyster cultivation equipment in the prior art, and to propose a method and equipment for cultivating luminous pearls.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. The present invention installs devices such as fan blades, damping devices and transmission frames. The fan blades rotate under the influence of water flow, so that the transmission frame drives the pearl oysters to rotate. The damping device reduces the rotation speed of the fan blades and reduces the rotational vibration. The water flow drives the fan blades to rotate and the water flow impacts the pearl oysters synchronously, simulating the situation that the pearl oysters are driven by the water flow in natural waters. The pearl oysters rotate and swing slightly in the water, thereby increasing their light receiving area, ensuring that all parts of the pearl oysters can get sufficient light. Uniform light can ensure that each pearl oyster can obtain enough light required for photosynthesis, which helps the pearl oysters secrete more uniform nacre, thereby improving the overall quality of pearls. Adequate light conditions can shorten the growth cycle of pearl oysters, accelerate the maturation rate of pearls, and thus improve breeding efficiency.

[0023] 2. The present invention cultured pearl oysters separately by installing the first net bag, the second net bag and the partition net, and divided the interior of the box into multiple breeding areas by the partition net, thereby reducing the accumulation of metabolic products and excrement per unit area, reducing the risk of water quality deterioration, and reducing competition and interference among pearl oysters, which is beneficial to the healthy growth and pearl formation of each pearl oyster. At the same time, it is convenient for breeders to manage and observe, and timely discover and deal with abnormal situations. The first net bag is distributed on the outer ring of the transmission frame, and the second net bag is distributed on the inner ring of the transmission frame. The first net bag is located below the second net bag. The vertical space is used to increase the breeding density, ensuring that each pearl oyster is exposed to approximately the same light intensity and the growth rate of each pearl oyster is similar. The breeder can plan and manage the breeding cycle more effectively, avoid waste of resources or low breeding efficiency due to different growth rates, thereby enhancing the practicability of the equipment.

[0024] 3. The present invention installs devices such as an LED light box cover, an electric telescopic rod and a support rod, and uses the electric telescopic rod to adjust the tilt angle of the box to ensure that the pearl oysters receive more uniform and sufficient light, which is helpful to promote the photosynthesis of the symbiotic algae in the pearl oysters and provide the pearl oysters with necessary nutrition and energy. When the light intensity is too strong, a sunscreen net is set to prevent the pearl oysters from being harmed by excessive light. In rainy weather or insufficient light, the LED light box cover is covered to simulate light to ensure that the pearl oysters can always obtain suitable light conditions. By flexibly adjusting the light conditions, the risk of abnormal growth or death of the pearl oysters due to insufficient or excessive light is reduced, thereby ensuring the stability and reliability of the entire breeding process.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figures 1 to 7 A method for cultivating luminous pearls comprises the following cultivation steps:

[0035] S1, install the equipment, place the diversion device 9 on the shore, insert the fixed pile 3 into the lake bottom mud, and make sure that the bottom of the base 4 is in full contact with the lake bottom;

[0036] S2, adjusting the device, starting the electric telescopic rod 5, moving the box 2 to a suitable water depth position, and controlling part of the electric telescopic rod 5 to adjust the tilt angle of the box 2;

[0037] S3, putting pearl oysters, placing the freshwater oysters to be cultured separately in a plurality of first net bags 17 and a plurality of second net bags 19 for culture, the fan blades 23 are affected by the water flow to drive the rotating rod 22 and the transmission frame 21 to rotate, and the transmission frame 21 drives the pearl oysters to rotate;

[0038] S4, adjust the water environment, the water quality detector 11 detects the pH, temperature and dissolved oxygen content of the aquaculture waters, and according to the test results, water or solution is transported through the water inlet 10, the diversion device 9 and the water outlet 12 to adjust the pH or temperature of the water area;

[0039] S5, sun protection, when the light intensity is too strong, connect the sun protection net to the top of the fixing ring 6 and the fixing block 16 on the column 15, and hang multiple layers of sun protection nets on the support rod 8;

[0040] S6. Simulate light. When the light time is insufficient in rainy weather, cover the LED light box cover 1. The LED light simulates the spectrum of sunlight, emitting visible light, infrared light, ultraviolet light and other light of different wavelengths, providing the pearl oysters with light conditions close to natural light.

[0041] A luminous pearl cultivation device is used in the luminous pearl cultivation method, comprising a base 4, a diversion device 9 is fixedly installed on the side wall of the base 4, and fixed piles 3 are fixedly installed on the bottom of the base 4 and the diversion device 9 respectively. The bottom of the fixed pile 3 is in a pointed cone shape, which is convenient for fixing the base 4 on the bottom of the lake to ensure that the growth of the pearl oysters is not disturbed by the external environment. A box 2 is fixedly installed on the top of the base 4 through a plurality of electric telescopic rods 5. When the water level of the lake changes, the box 2 can automatically adjust the height by the extension and contraction of the electric telescopic rods 5, so that the pearl oysters are always in a water depth suitable for growth. At the same time, the distance between the pearl oysters and the water surface can be adjusted to control the light intensity, thereby providing a suitable environment for the growth of the pearl oysters. The electric telescopic rods 5 are partially extended and contracted, and the entire box 2 is slightly tilted, so that the pearl oysters can receive more light. The box 2 is made of a plastic mesh, which can allow lake water and the water of the box 2 to exchange better, which is conducive to the entry of microorganisms and phytoplankton in the lake into the box 2 as bait for the pearl oysters. At the same time, the metabolic products of the pearl oysters can be diluted by the lake water, which is conducive to protecting the water environment.

[0042] A plurality of support rods 8 for installing a sunscreen net are arranged on the top of the box body 2, and an LED light box cover 1 is arranged on the top of the box body 2. The LED light box cover 1 is used to simulate the spectrum of sunlight in rainy weather, including light of different wavelengths such as visible light, infrared light and ultraviolet light, so as to provide lighting conditions close to natural light for pearl oysters. A plurality of breeding cages are arranged inside the box body 2, and the plurality of breeding cages are evenly distributed inside the box body 2, and partition nets 7 are respectively arranged between the plurality of breeding cages to prevent the pearl oysters from escaping, so as to ensure that they grow and reproduce in the specified area, so that the breeding areas are clearly divided, and it is convenient to carry out different management and treatment of pearl oysters in different areas, improve the breeding efficiency, help to control the number and density of pearl oysters in each breeding component, avoid competition and growth problems caused by excessive crowding, and enable them to obtain sufficient food and growth space, thereby improving the growth rate and quality of pearl oysters.

[0043] The breeding cage is composed of a fixing ring 6, a bottom plate 14 and a plurality of columns 15. The bottom plate 14 is fixedly mounted on the bottom of the inner wall of the box body 2. The fixing ring 6 is located above the bottom plate 14. A plurality of columns 15 are distributed in a circular array on the top of the bottom plate 14 and are fixedly connected to the bottom plate 14. The tops of the plurality of columns 15 are fixedly connected to the bottom of the fixing ring 6. The side walls of the plurality of columns 15 and the top of the fixing ring 6 are respectively fixedly mounted with fixing blocks 16. The fixing blocks 16 are used to install a sunscreen net. When the light is too strong, the sunscreen net can prevent the sunlight from directly shining on the water surface, play a role of sunshade, and help to reduce the water temperature and maintain a suitable water temperature environment. The sun protection net can also prevent impurities, leaves and other debris in the water from entering the breeding area, reducing interference and damage to the pearl oysters. Two arc plates 13 are symmetrically distributed on the side wall of the bottom plate 14. The two arc plates 13 are fixedly connected to the bottom plate 14, and a reflective film is provided on one side of the arc plate 13 close to the bottom plate 14. The reflective film can increase the reflection and scattering of light, so that the light reflected on the pearl oysters is more uniform. The arc plate 13 can also block the impact of water flow to maintain the stability of the pearl oyster breeding environment.

[0044] A rotating rod 22 is rotatably connected at the center of the top of the bottom plate 14, a damping device 24 is fixedly installed on the outer wall of the rotating rod 22, a fan blade 23 is fixedly installed on the outer wall of the damping device 24, a transmission frame 21 is fixedly installed on the side wall of the rotating rod 22, and the transmission frame 21 is located above the fan blade 23. The fan blade 23 rotates under the influence of the water flow, so that the transmission frame 21 drives the pearl oyster to rotate. When the fan blade 23 rotates, the damping device 24 plays a role in reducing the rotation speed of the fan blade 23 and reducing the rotation vibration, ensuring that the pearl oyster is more stable when rotating, reducing the negative impact of the rotation on the pearl oyster, and the water flow drives the fan blade 23 to rotate and the water flow impacts the pearl oyster. At the same time, the situation of pearl oysters being driven by water flow in natural waters is simulated. This simulation helps pearl oysters to adapt to the environment better and reduces the impact of artificial breeding. Pearl oysters rotate and swing slightly in the water, thereby increasing their light receiving area and ensuring that all parts of the pearl oysters can get sufficient light, which helps them grow evenly. During the rotation of the fan blades 23, the kinetic energy of the water flow is converted into mechanical energy. This energy conversion not only helps the operation of the device, but also effectively disperses and reduces the impact force of the water flow, so that the entire breeding cage will not shake violently due to the water flow, providing a more stable growth environment for the pearl oysters.

[0045] The bottom of the transmission frame 21 is fixedly connected with a plurality of first net bags 17 and a plurality of second net bags 19 through a rigid rod 20. Each pearl oyster has its own net bag, so that individuals will not excessively compete for resources, reduce the pressure between individuals, and is conducive to the growth and survival of the pearl oysters. The plurality of first net bags 17 are distributed in a circular array on the outer ring of the transmission frame 21, and the plurality of second net bags 19 are distributed in a circular array on the inner ring of the transmission frame 21. The height of the first net bag 17 is lower than that of the second net bag 19. The vertical space is used to increase the breeding density, and at the same time, it is ensured that each pearl oyster is subjected to roughly the same light intensity, so that the growth rate of each pearl oyster is similar, and the pearl oysters are avoided from competing with each other. The net bags are shielded to ensure that each pearl oyster can get enough light. Adjacent net bags are fixedly connected with elastic ropes 18. The elasticity of the elastic ropes 18 allows the pearl oysters to move freely within a certain range, which helps them to carry out some natural activities to promote their growth and health. At the same time, it can stimulate the mantle to secrete nacre, which is helpful for the formation of pearls and the improvement of their quality. The flow of water will cause the pearl oysters to swing or move in the net bag, and the elastic elastic ropes 18 can provide a certain elasticity to reduce the impact and damage of the water flow on the pearl oysters, ensuring that the pearl oysters remain active in the water while avoiding accidental damage or collision that may be caused by excessive movement.

[0046] The top of the diverter device 9 is fixedly connected to a water inlet 10, and the side of the diverter device 9 close to the box body 2 is fixedly connected to a water outlet 12. A valve is provided on the side wall of the water outlet 12, and a water quality detector 11 is fixedly installed on the side wall of the water outlet 12. The water quality detector 11 is used to detect the pH, temperature and dissolved oxygen content of the water area where the breeding equipment is located. Water or solution is transported through the water inlet 10 to adjust the pH or temperature of the breeding water area. The water discharged from the water outlet 12 flows to the bottom of the breeding cage. By effectively diverting and discharging the water source, it is ensured that the water area of ​​each group of breeding components can be properly adjusted, thereby meeting the growth needs of pearl oysters and improving breeding efficiency.

[0047] In the present invention, when breeding freshwater clams, first place the entire breeding box on the shore of the lake, place the diversion device 9 close to the shore, and insert the entire breeding box into the lake bottom mud through the fixed pile 3 until the base 4 touches the lake bottom. Then start the electric telescopic rod 5 to move the box 2 to a suitable water depth. In addition, the electric telescopic rod 5 can be partially telescopic, and the entire box 2 can be tilted slightly so that the pearl oysters can receive more light. The entire box 2 is composed of a plastic mesh and is fixed by a support rod 8. The breeding cages inside the box 2 are separated by a partition net 7. The partition net 7 can not only effectively prevent collisions between breeding cages and reduce damage to the breeding cages due to mutual friction, but also help maintain a relatively stable growth environment. At the same time, the presence of the partition net 7 can also prevent the pearl oysters from accidentally falling out of the breeding cages, avoiding them from being washed away by the water flow or encountering other potential threats.

[0048] Freshwater clams that need to be cultivated will be placed separately in the first net bag 17 and the second net bag 19. The separate hanging cultivation allows the breeder to observe and record the growth of each pearl oyster more accurately, discover and deal with any possible growth problems in time, and obtain higher quality pearls. The first net bag 17 is in the outer circle of the breeding cage, and the second net bag 19 is in the inner circle of the breeding cage, and the first net bag 17 is located at the bottom, and the second net bag 19 is located at the top. This is because the outer circle will be directly exposed to the external environment and can receive more direct and strong sunlight. In contrast, the light intensity of the inner circle will be relatively weak, so the first net bag 17 is in a slightly deeper water layer, using the natural filtering effect of the water body to reduce the light intensity, and the second net bag 19 is in a slightly shallower water layer to obtain stronger light, so that the pearl oysters can receive roughly the same light intensity, ensuring that the growth rate of each pearl oyster is similar, and the breeder can more effectively plan and manage the breeding cycle to avoid waste of resources or low breeding efficiency due to different growth rates. In addition, when pearl oysters are closely arranged or stacked together, the upper oysters often block the light of the lower oysters, resulting in insufficient light for the lower oysters, affecting their normal growth and the quality of the pearls. This distribution method avoids the oysters blocking each other and ensures that each oyster can get enough light.

[0049] Each net bag is fixed on the transmission frame 21 by a rigid rod 20, so that a safe distance can be ensured between each net bag, and it is not easy to collide. And each net bag is connected with an elastic rope 18, which has a certain elasticity, so that the pearl oysters can move freely within a certain range. This mobile space helps the pearl oysters to remain active in the water, which is beneficial to their growth and health, but does not allow the movement of the pearl oysters to be too random, thereby avoiding accidental damage or collision that may be caused by excessive movement. The arc plate 13 on both sides of the bottom plate 14 is also equipped with a reflective film, which can increase the reflection and scattering of light, so that the light reflected on the pearl oysters is more uniform. There are fixed blocks 16 on the top of the breeding cage and the column 15. When the sunlight is too strong, the sunscreen net can be fixed on it to reduce the direct sunlight. A sunscreen net can also be hung on the support rod 8. The structural design of the multi-layer sunscreen net is more complicated. Each layer can reflect and scatter sunlight to a certain extent, thereby effectively reducing the penetration of light and achieving a better shading effect. However, while blocking strong sunlight, it still allows an appropriate amount of light to pass through, maintaining a certain illumination and transparency.

[0050] When the breeding cage is placed in the water, the water flow will flow between the two arc plates 13. At this time, the impact of the water flow will drive the fan blades 23 to rotate, and the rotation of the fan blades 23 will drive the rotating rod 22 to rotate, thereby causing the transmission frame 21 to rotate. The transmission frame 21 will drive the pearl oysters to rotate, and during this rotation process, the pearl oysters can be exposed to more uniform light. When the fan blades 23 rotate, the damping device 24 will reduce the rotation speed of the fan blades 23, and at the same time reduce the vibration during rotation, so that the pearl oysters are more stable during rotation. In addition, due to the existence of the damping device 24, the rotation of the fan blades 23 is very slow, and the water flow drives the fan blades 23 to rotate and the water flow impacts the pearl oysters synchronously, so that the situation of the pearl oysters being driven by the water flow in the water can be simulated, and the influence of the rotation on the pearl oysters can be reduced. In addition, through the connection of the elastic rope 18, the pearl oysters can rotate and swing slightly in the water, which can increase their light receiving area, thereby ensuring that each part of them can get sufficient light. In addition, during the rotation of the fan blades 23, the kinetic energy of the water flow is converted into mechanical energy, which can effectively disperse and reduce the impact force of the water flow, so that the entire breeding cage will not shake violently.

[0051] The water quality detector 11 will detect the pH, temperature and dissolved oxygen content of the water area where the breeding box is located. When the result does not meet the pearl oyster breeding standards, water or solution can be transported through the water inlet 10 to adjust the pH or temperature of this water area. The impact of the water flow will also make the flow rate of this water area faster, more effectively bring oxygen from the air into the water, and distribute the oxygen more evenly through the movement of the water body. The diverter device 9 will discharge the liquid from the bottom of the breeding cage through the water outlet 12. By effectively diverting and discharging the water source, it can be ensured that the water area of ​​each breeding cage can be properly regulated, thereby meeting the growth needs of aquatic organisms and improving breeding efficiency. In addition, discharging from the bottom of the breeding cage can also reduce the impact of the water flow impact on the breeding cage. The arc plate 13 on the breeding cage can also slightly block the impact of the water flow to maintain the stability of the pearl oyster breeding environment.

[0052] When it is rainy or cloudy and the light exposure time is insufficient, the LED light box cover 1 can be covered. The LED light can simulate the spectrum of sunlight, including visible light, infrared light, ultraviolet light and other different wavelengths of light, to provide the pearl oysters with lighting conditions close to natural light. This lighting environment simulating natural light helps the pearl oysters to carry out normal physiological activities, promote their healthy growth and the formation of pearls.
