Description

Technical Field

[0001] The invention relates to the technical field of algae cultivation, and in particular to an ecological algae reef based on artificial light source growth promotion. Background Art

[0002] Seaweed fields are an important part of the offshore ecosystem. They are habitats formed by the attachment of large benthic algae, and play an important role in the material cycle and maintaining the balance of offshore ecology in the offshore ecosystem. As photosynthetic autotrophic organisms, large algae can obtain light energy through photosynthesis to ensure their own growth and proliferation. In the process, they absorb inorganic carbon and nutrients such as nitrogen and phosphorus in the water, release oxygen, and improve water quality, release oxygen and fix carbon. At the same time, as primary productivity, large algae can continuously provide food for marine herbivorous animals. Its fallen leaves, rhizomes and other tissues produce debris under the scouring of waves, which can be used by animals and microorganisms that eat debris. In addition. During the growth of large algae, a complex spatial structure is formed inside the seaweed field, which can provide a place for small marine organisms to avoid predators. Moreover, since the surface area of ​​large algae leaves is large, it is conducive to the attachment of fish eggs and increases the survival rate of biological larvae.

[0003] In recent years, affected by factors such as global climate change, ocean acidification and human activities, many coastal countries around the world have experienced serious declines in seaweed fields. Since the 1980s, my country's seaweed fields have also faced serious degradation problems. In order to curb the decline of seaweed fields, based on ecological principles, a method based on bioremediation and combined with artificial assisted restoration has been adopted to improve the effect of seaweed beds through optimized configuration. In terms of artificial assistance, artificial algae reefs are currently mostly deployed to provide attachment base structures for large algae and promote the establishment of large algae on the reef. At present, the water depth of the sea area where artificial algae reefs are deployed generally does not exceed 6m. This is because light is the key factor affecting the growth of large algae, and water depth and transparency are the main factors affecting light intensity. Due to the limitation of light, the establishment effect of large algae on artificial algae reefs is inhibited, and the seaweed field restoration area is also limited. Summary of the invention

[0004] The purpose of the present invention is to provide an ecological algae reef based on artificial light source promotion to solve the problems existing in the above-mentioned prior art, overcome the light limitation, and be conducive to promoting the establishment and expansion of large algae in deeper waters, expanding the seaweed field restoration area, and having positive significance for the restoration of seaweed fields and the creation of seaweed field habitats.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide an ecological algae reef based on artificial light source promotion to solve the problems existing in the prior art, overcome the light limitation, and be conducive to promoting the establishment and expansion of large algae in deeper waters, expanding the seaweed field restoration area, and having positive significance for the restoration of seaweed fields and the creation of seaweed field habitats.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1-Figure 3 As shown, the present invention provides an ecological algae reef based on artificial light source promotion, including a reef body 1, a support frame, a light energy conversion unit and a light-making unit; a hollow cavity is provided inside the reef body 1; the support frame includes a frame body 3, a support rod 5 and a plurality of hollow tubes 2; the frame body 3 is located above the reef body 1; the support rod 5 is located above the frame body 3 and is connected to the upward side of the photovoltaic panel 4; each hollow tube 2 connects the frame body 3 and the reef body 1; the light energy conversion unit includes a photovoltaic panel 4 and a battery; the photovoltaic panel 4 is arranged at the upper end of the frame body 3 and is above the sea surface with the help of the frame body 3; the battery is located in the hollow cavity; the photovoltaic panel 4 is connected to the battery with the help of an insulated wire running through the hollow tube 2; the light-making unit includes a plurality of electric light sources 7 arranged on the outside of the reef body 1, and the electric light source 7 is electrically connected to the battery.

[0032] Compared with the prior art, the ecological algae reef based on artificial light source promotion provided by the present invention adds a photovoltaic panel 4 at the upper end of the reef body 1, and uses the hollow cavity of the reef body 1 to hold a battery, and uses the battery as the power source of the electric light source 7, so that the electric light source 7 emits light to provide better lighting conditions for the growth of seaweed on the outside of the reef body 1, which solves the problem of seaweed fields being limited by light, improves the growth efficiency of seaweed and the speed of restoration of the seaweed field habitat, is conducive to promoting the planting and propagation of large algae in deeper waters, and expanding the seaweed field restoration area, which has positive significance for the restoration of seaweed fields and the creation of seaweed field habitats.

[0033] Specifically, the reef 1 serves as the main body of the algae reef, and its surface layer is used for seaweed attachment; the algae reef is hoisted into the sea, and the reef 1 is located below the sea surface and the reef 1 is suspended by means of its hollow cavity structure. The reef 1 is made of a cement mixture with 20% oyster shells with a particle size of 1-2 mm added, which can be set as a regular cube, such as length × width × height: 2m × 2m × 2m, thickness: 10cm. A hollow cavity with an opening facing upward is opened in the middle of the regular cube. Holes of 1.5m × 0.25m are opened on the four sides of the reef 1 at 20cm from its top and bottom surfaces. Pits with a radius of 2.5cm are uniformly made on the four sides of the reef 1 through a mold. The pits are used to increase the roughness on the side walls and increase the inclined surface of the side walls to facilitate the attachment of large algae.

[0034] The photovoltaic panel 4 located above the reef 1 is located about 2m above the sea level, and in order to improve the conversion efficiency of the photovoltaic panel 4, the angle between the photovoltaic panel 4 and the sea level is set to 30°-45°, and the optimal angle is 40°. The photovoltaic panel 4 needs to face due south. The photovoltaic panel 4 is made of crystalline silicon. The photovoltaic panel 4 generates current after being irradiated by sunlight, and the current is transmitted through an insulated wire and stored in the battery. The photovoltaic panel 4 and the battery are connected by insulated wires. Since the reef 1 and the battery are both located below the sea level, in order to protect the battery from seawater erosion, the outside of the battery needs to be wrapped with waterproof and anti-corrosion materials, such as polyurethane materials.

[0035] The insulated wire connects the photovoltaic panel 4 and the storage battery. To protect the insulated wire from being corroded by seawater, the insulated wire can be inserted into the hollow tube 2. The diameter of the insulated wire can be selected to be 2.5 mm.

[0036] The hollow tube 2 is used as a support, and a harmless stainless steel tube with a diameter of 2 cm is used. One end of the stainless steel tube is connected to the frame 3, and the other end extends to the inside of the reef 1. The hollow tube 2 includes a threading tube and a support tube, wherein the threading tube is used to pass the insulated wire and connect the battery, and the support tube is used to connect the frame 3 and the reef 1, and is used to fix the frame 3 on the top of the reef 1. The support tube is connected to the reef 1 by casting or bolting.

[0037] The electric light source 7 is a strip light source arranged on the outer wall of the reef body 1. The wiring terminal of the strip light source extends into the hollow cavity and is connected to the battery by means of a pin plug.

[0038] Specifically, the strip light source can be an LED light strip horizontally wound around the circumference of the reef body 1, and the end of the light strip extends into the hollow cavity and is connected to the battery by means of a pin plug. The light strip is wound around the upper and middle parts of the reef body 1 at least once each, and is fixed at the corners of the reef body 1 and connected to the battery. The outer side of the wire of the light strip is wrapped with a waterproof and anti-corrosion material, and the end of the wire of the light strip extends to the battery and is connected by means of a pin plug. The pin plug is a way of plugging, which can be disassembled under the action of external force.

[0039] The strip light source may also be a lamp post, which is arranged in a horizontal direction or a vertical direction.

[0040] In order to prevent the light source from being blocked, a light source cleaning component is installed on the reef body 1, and the light source cleaning component includes a mounting frame and a cleaning brush. The outer wall of the reef body 1 is provided with cleaning brushes respectively matched with the outer walls of each strip light source. The mounting frame includes a slide rail 24 and an extension rod 25. The length direction of the slide rail 24 is consistent with the length direction of the strip light source and is located on one side of the strip light source. An extension rod 25 is slidably connected to the slide rail 24. The extension rod 25 is perpendicular to the length direction of the strip light source. The extension rod 25 covers one or more strip light sources. A cleaning brush is installed on the side of the extension rod 25 close to the strip light source. The cleaning brush corresponds to the strip light source one by one. A conveyor belt 28 corresponding to the slide rail 24 is also provided on the outer wall of the reef body 1. The extension rod 25 is fixed on the conveyor belt 28. The conveyor belt 28 is connected to the driven wheel 29 and the driving wheel 30 in a transmission manner. The driven wheel 29 and the driving wheel 30 are both installed on the reef body 1, at the four corners of the top of the reef body 1. Driven wheels 29 are installed at three of the locations, and a driving wheel 30 is installed at another location. The driving wheel 30 is connected to the output shaft of the driving motor. For example, a first pulley 31 can be installed on the axle of the driving wheel 30, and a second pulley 32 can be installed on the output shaft of the driving motor. The first pulley 31 and the second pulley 32 are connected to each other through a belt 33. The conveyor belt 28 is driven by the driving motor to move, and then the extension rods 25 are driven to move along the slide rail 24, thereby driving the cleaning brush to move along the length direction of the strip light source to remove algae attached to the outer wall of the strip light source.

[0041] When the strip light source adopts a lamp post, the lamp post can be fixed at both ends, and the middle part can be suspended. At this time, the cleaning brush is annular, and the annular cleaning brush moves along the length direction of the lamp post under the drive of the driving motor to clean the surface of the lamp post.

[0042] The slide rail adopts a rust-proof and corrosion-proof linear guide rail. The cleaning brush includes a U-shaped fixing frame 26 and a brush layer 27 located inside the fixing frame 26. The fixing frame 26 is connected to the extension rod 25, and the inner side wall of the brush layer 27 is U-shaped, and the inner side wall of the U-shaped is used to wrap the outer side of the lamp post.

[0043] The light-making unit also includes an avoidance warning light group 6, which includes two groups of light sources respectively arranged on both sides of the support frame, and the number of light sources in each group is at least one; the light source is electrically connected to the battery. The avoidance warning light group 6 is located on both sides of the frame 3, and there are at least two groups of light sources. The colors of the two groups of light sources are different to distinguish the positions on both sides of the reef 1. For example, the colors of the two groups of light sources are red and green respectively, and they are distributed according to the principle of left red and right green. The avoidance warning light group 6 is electrically connected to the battery to ensure the safety of the reef 1 in bad weather.

[0044] In some embodiments, see Figure 1 to Figure 2The hollow cavity of the reef body 1 is connected from top to bottom, and the support frame also includes a main rod 9, a sealing box and a bottom plate 8 which are arranged in sequence; the upper end of the main rod 9 is connected to the middle of the lower end of the frame body 3; the sealing box is connected to the lower end of the main rod 9 and is located in the hollow cavity, and the sealing box is used to contain batteries; the bottom plate 8 is arranged at the lower end of the sealing box and extends outward to the bottom of the reef body 1 to support the reef body 1.

[0045] The hollow cavity provided in the middle of the reef body 1 is provided to be through-through from top to bottom and allows the main rod 9 and the sealing box to pass through, and the bottom plate 8 is provided at the lower end of the sealing box and connected to the bottom of the reef body 1. The bottom plate 8 is used to support the reef body 1 and connect the reef body 1 and the sealing box.

[0046] The sealed box is made of waterproof and anti-corrosion materials, such as polyurethane materials. The battery is placed in the sealed box, and the threading holes opened on the side wall of the sealed box are all provided with sealing rings to prevent seawater erosion. The drive motor is arranged in the sealed box, and the output shaft of the drive motor passes through the sealed box upward and is sealed and connected to the sealed box. After passing through the sealed box, the output shaft of the drive motor is connected to the second pulley 32, and the second pulley 32 is connected to the first pulley 31 on the axle of the driving wheel 30 through a belt 33.

[0047] The upper end of the sealed box is connected to the frame 3 by means of a main rod 9, and the lower end of the sealed box is connected to a bottom plate 8. The bottom plate 8 is a wooden base, which sinks into the sea water along with the reef 1 and is continuously eroded by the sea water. During the erosion process, nutrients suitable for algae growth are produced, which promotes the rapid growth of algae. The bottom plate 8 can be a porous plate or a plate frame.

[0048] When the bottom plate 8 is corroded, the sealing box and the support frame can be separated from the reef body 1 by disassembling the hollow rod. After separation, the support frame and the light energy conversion unit can be recycled and reused.

[0049] The service life of a conventional crystalline silicon photovoltaic panel 4 is about 25 years. Recycling the photovoltaic panel 4 in time can reduce costs and light pollution.

[0050] The main rod 9 is used as a load-bearing rod, and is fixedly connected to the upper end of the sealed box. The outer side of the main rod 9 is treated with waterproof and anti-corrosion. The main rod 9 can be made of metal material, and an anti-corrosion layer is plated on the outer layer.

[0051] In some embodiments, see Figure 1 to Figure 2 The bottom plate 8 includes a fixed portion 13 and a plurality of movable portions 14, wherein the fixed portion 13 is connected to the bottom of the sealed box; each movable portion 14 is radially rotatably connected to the outer edge of the fixed portion 13, and a flow space is left between two adjacent movable portions 14; when the movable portion 14 is in an unfolded state, the movable portion 14 is used to support the reef body 1; when the movable portion 14 is flipped and retracted, the longitudinal projection area of ​​the movable portion 14 is smaller than the flow area of ​​the hollow cavity.

[0052] Considering that there is a difference between the corrosion rate of the wooden base and the growth rate of the seaweed, and when the seaweed grows, the base cannot be completely corroded, which will affect the recycling and reuse of the photovoltaic panel 4. Therefore, the base is divided into a wooden part and a metal part, wherein the wooden part is slowly corroded by seawater, while the metal part is recycled; when the wooden part is not completely corroded, the wooden part can also be recycled.

[0053] Specifically, the fixing portion 13 of the bottom plate 8 is made of metal material, and the metal material is fixed to the bottom of the sealed box. A plurality of movable portions 14 are evenly distributed around the fixing portion 13, and the movable portions 14 are made of wood. The movable portion 14 is flipped around the longitudinal plane and fixed to the bottom of the reef body 1. When the reef body 1 is installed before launching into the water, the movable portion 14 is retracted, and the movable portion 14 in the retracted state extends downward, and the longitudinal projection area of ​​the movable portion 14 is smaller than the flow area of ​​the hollow cavity. The entire movable portion 14 can penetrate the hollow cavity from top to bottom and extend to the bottom of the reef body 1; when the movable portion 14 extends to the bottom of the reef body 1, the movable portion 14 is unfolded, and the movable portion 14 extends horizontally outward and is supported on the lower end of the reef body 1. The movable portion 14 is fixed to the lower end of the reef body 1 by a detachable method such as snap-on.

[0054] After the reef 1 is placed in the seawater, when it is recovered, if the wooden part is completely corroded, only the metal part of the support frame and the base is recovered. If the wooden part is not completely corroded, the wooden part is separated from the lower end of the reef 1 and recovered. Specifically, the separation of the free part from the reef 1 can be assisted by external operation.

[0055] The lower end of the hollow tube 2 is interference fit with the reef body 1. When the hollow tube 2 is lifted, the hollow tube 2 is separated from the reef body 1 under the action of the gravity of the reef body 1 and the force of the hook.

[0056] In some embodiments, see Figure 2 A telescopic member is provided at the lower part of the sealing box, and the telescopic member extends downward to drive the movable part 14 to retract.

[0057] Specifically, a partition 20 is provided in the sealed box, which divides the sealed box into an upper battery chamber 18 and a lower drive chamber; the battery is located in the battery chamber 18; a downwardly extending telescopic member is provided in the drive chamber, the telescopic member passes through the bottom plate 8 and extends downward, and the free end of the telescopic member is hingedly connected to a plurality of traction rods 15, and the plurality of traction rods 15 correspond to and are hinged to the plurality of movable parts 14 one by one; the plurality of traction rods 15 are used to drive the movable parts 14 to flip downward.

[0058] The telescopic member in the driving chamber includes a telescopic drive 17 and a driving rod 16 disposed at the end of the telescopic drive 17. The telescopic drive 17 can be an electric push rod, etc. The driving rod 16 extends from the bottom of the sealed box and slides relative to the bottom of the sealed box. The gap between the driving rod 16 and the bottom plate 8 at the lower end of the sealed box is sealed by a sealing ring.

[0059] The lower end of the driving rod 16 is connected to a connecting plate, and a plurality of traction rods 15 are evenly distributed around the connecting plate, and the two ends of the plurality of traction rods 15 are respectively hinged to the connecting plate and the lower end of the movable part 14. When the driving rod 16 moves downward, the traction rods 15 drive the movable part 14 to move downward, so as to retract the movable part 14 inward.

[0060] When the wooden structure of the bottom plate 8 does not exist, the bottom plate 8 with a metal structure can be recovered by means of the telescopic member and the pulling rod 15 .

[0061] In some embodiments, see Figure 2 A flow gap is left between the reef body 1 and the outer wall of the sealing box, and the flow gap is connected to the flow space; the reef body 1 is provided with a plurality of flushing holes 11 which are arranged obliquely and penetrate the side wall of the reef body 1, and the inlet end of the flushing hole 11 is connected to the flow gap, and the inlet end of the flushing hole 11 is higher than the outlet end of the flushing hole 11.

[0062] There is a gap between the reef body 1 and the outer wall of the sealing box, which is a flow gap. The flow gap connects the upper opening and the lower opening of the reef body 1. Under turbulent conditions, seawater will enter from the upper opening of the flow gap and be discharged from the lower opening of the flow gap.

[0063] The flushing hole 11 opened on the side of the reef body 1 is connected to the flow gap. When the seawater fluctuation causes the seawater pressure in the flow gap to fluctuate, the seawater will enter the flushing hole 11 from the flow gap under the action of the inner and outer pressures and spray out from the outer side of the flushing hole 11 to flush the outer wall of the reef body 1. The inclined setting of the flushing hole 11 is more conducive to the flow of seawater.

[0064] In some embodiments, see Figure 2 A plurality of horizontally arranged deformation grooves 12 are provided on the outer side of the reef body 1 , and the deformation grooves 12 are longitudinally spaced apart; the outlet end of the flushing hole 11 is opened in the deformation groove 12 .

[0065] The deformation grooves 12 extend horizontally, and the depth direction of the deformation grooves 12 is consistent with the thickness direction of the reef body 1. The deformation grooves 12 are spaced apart longitudinally, and the inclined surfaces of the deformation grooves 12 increase the attachment area for the growth of seaweed and improve the growth rate of seaweed.

[0066] The outlet of the flushing hole 11 is located at the upper part of the deformation groove 12 and faces the inclined surface of the lower end of the deformation groove 12, which is more convenient for flushing the sediment on the inclined surface of the lower end.

[0067] In addition, a spiral guide vane 10 is provided on the outer side of the main rod 9, and the radial length of the spiral guide vane 10 gradually decreases from top to bottom; a guide platform 19 is provided between the spiral guide vane 10 and the sealing box, and the guide platform 19 is a conical platform.

[0068] The blade radius of the spiral guide vane 10 gradually decreases from top to bottom, which is used to increase the influence range of the guide. When the seawater fluctuates and flows onto the spiral guide vane 10, it will be affected by the spiral guide vane 10 and flow downward in a spiral shape until it flows through the flow gap in a spiral shape, thereby increasing the disturbance state of the water flow and improving the flushing flow rate of the flushing hole 11.

[0069] A guide platform 19 is also provided at the upper end of the sealing box. The guide platform 19 is a conical platform. The cross-sectional area of ​​the upper end of the guide platform 19 is smaller than the cross-sectional area of ​​the lower end thereof. A bell mouth is formed at the upper end of the flow gap, which effectively promotes the entry of water flow.

[0070] In some embodiments, see Figure 2 A heating component is provided on the outside of the sealed box; the heating component includes a heat-insulating bottom layer 23, a coil layer and a heat-radiating plate 21; the heat-insulating bottom layer 23 is provided on the outside of the sealed box; the coil layer includes a plurality of sheet coils 22, and the plurality of sheet coils 22 are sequentially arranged on the outside of the heat-insulating bottom layer 23; a heat-radiating plate 21 is correspondingly provided on the outside of each sheet coil; the heat-radiating plate 21 is spaced apart from the inner wall of the reef body 1.

[0071] The outer side of the sealed box is wrapped with a heat-insulating bottom layer 23, and a plurality of sheet coils 22 are evenly arranged between the heat-insulating bottom layer 23 and the heat-radiating plate 21. After being powered on, the sheet coils 22 are combined with the heat-radiating plate 21 to form an electromagnetic heater, which can heat the water temperature in the flow gap between the heat-radiating plate 21 and the reef body 1 and transfer heat to the reef body 1. When the water temperature in the flow gap rises, it can not only mix with the surrounding lower-temperature seawater through the flushing hole 11 or the flow space as the seawater fluctuates, thereby alleviating the temperature of the surrounding seawater, but also transfer heat to the reef body 1, so that the reef body 1 always maintains a more suitable temperature, so as to adapt to the temperature requirements of the growth environment of seaweed at various stages of growth.

[0072] If the reef body 1 is in a cubic shape, the cross-section of the hollow cavity inside it is circular or square. When the hollow cavity is square, there are four sheet coils 22, and the four sheet coils 22 correspond to the four inner walls of the reef body 1 respectively.

[0073] The edge of the heat dissipation plate 21 is wrapped by a sealing shell made of a polymer material, and the coil layer is sealed at the same time.

[0074] Since different algae growth stages require different environmental temperatures, the suitable temperature for conchospore germination and seedling growth of most species is higher than the suitable temperature for leafing stage; for example, the temperature of sea millet in the early and late cultivation stages is different. In the early stage of sea millet branch cultivation, the seawater temperature is adjusted to 15-17°C; in the late stage of sea millet branch cultivation, the seawater temperature is adjusted to 20-22°C. Therefore, by adjusting the surrounding water temperature and the temperature of the reef 1 through the heating component, the temperature requirements of seaweed growth at different stages can be met, thereby ensuring the growth rate of seaweed.

[0075] Therefore, adding a heating component inside the reef body 1 can appropriately increase and adjust the temperature of the reef body 1 and the ambient temperature around the reef body 1, ensuring that the ambient temperature during the spore growth period can be reached, and can slowly adjust the temperature with the growth period of the seaweed, finally allowing the seaweed to fully adapt to the seawater temperature.

[0076] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
