Description

Technical Field

[0001] This application relates to the technical field of marine ecological restoration, and particularly to an ecological restoration device and a marine restoration method. Background Art

[0002] Pollution-tolerant algae provide a low-cost and sustainable solution for marine pollution restoration through functions such as adsorption, metabolism, and ecological reconstruction. When the concentration of organic matter in water is too high, pollution-tolerant algae can absorb nitrogen and phosphorus organic pollutants such as urea, amino acids, and phosphate esters, as well as refractory and toxic substances such as lignin and phenols, and can even adsorb heavy metals. Given this characteristic of algae, using algae to repair marine waters in coastal areas has become an effective technical means.

[0003] In the method of using pollution-tolerant algae to repair the ocean, it is usually necessary to set up an attachment bed. The core purpose is to optimize its growth environment through artificial intervention, create an "artificial ecological niche", and break through the limitations of the natural environment through physical stability, spatial orientation, and community regulation to maximize its repair potential and improve the repair efficiency and ecological stability of pollution-tolerant algae to pollutants.

[0004] However, in existing pollution-tolerant algae attachment beds, multiple attachment substrates for pollution-tolerant algae to attach are usually arranged in an up-and-down stacked manner, and the positions of the attachment substrates are basically kept fixed. This easily affects the lighting effect of the pollution-tolerant algae on the lower attachment substrate, thereby affecting the normal growth of the pollution-tolerant algae and further affecting the effect of marine ecological restoration. Summary of the Invention

[0005] This application provides an ecological restoration device and a marine restoration method, which can effectively improve the lighting effect received by pollution-tolerant algae, thereby enabling the pollution-tolerant algae to maintain their activity and further improving the effect of marine ecological restoration.

[0006] On the one hand, this application provides an ecological restoration device, adopting the following technical solution: An ecological restoration device includes a floating component, an attachment component, a supplementary lighting component, and an energy supply component; The floating component includes a floating board and an ecological cage; the floating board floats on the sea surface, the ecological cage is arranged at the bottom of the floating board, the interior of the ecological cage has an ecological space for the growth of pollution-tolerant algae, the top of the floating board has a lighting opening for the ecological space to communicate with the space above the sea, and the bottom of the ecological cage has a sewage outlet communicating with the ecological space; The attachment component includes a plurality of attachment cylinders and a first driving member; the outer side of the attachment cylinder is for fouling-resistant algae to attach and grow, which is arranged in the ecological space and is rotatably connected to the ecological cage, and the rotation axes of the plurality of attachment cylinders are parallel to each other; the first driving member is arranged on the top of the floating plate and is used to drive the plurality of attachment cylinders to rotate synchronously and in the same direction; The supplementary lighting component includes a plurality of first supplementary lighting members and a plurality of second supplementary lighting members corresponding to the plurality of attachment cylinders one by one; the first supplementary lighting member is arranged inside the corresponding attachment cylinder, which emits light outward and the attachment cylinder is light-transmissive; the second supplementary lighting member is arranged in the ecological space and is located below the corresponding attachment cylinder, and it emits light upward; The power supply component includes a plurality of solar panels and a power supply member; the solar panels are arranged on the top of the floating plate, the solar panels are electrically connected to the power supply member, and the power supply member is simultaneously electrically connected to the first driving member and the supplementary lighting component; the power supply member is signal-connected to both the solar panels and the supplementary lighting component. When the power supply of the solar panels is lower than a certain value, the power supply member controls the operation of the supplementary lighting component.

[0007] By adopting the above technical solutions, when the lighting conditions are sufficient, the continuously rotating attachment cylinders can enable the fouling-resistant algae attached to their outer sides to evenly absorb sunlight, thereby effectively improving the growth efficiency of the fouling-resistant algae; when the lighting conditions are insufficient, the supplementary lighting component can temporarily supplement the lighting conditions for the fouling-resistant algae to effectively ensure the vitality of the fouling-resistant algae. At the same time, during the process of the supplementary lighting component supplementing light at night, it can increase the temperature of the environment around the fouling-resistant algae to a certain extent, enabling the fouling-resistant algae to grow in a more suitable temperature environment, thereby further improving the effect of marine ecological restoration.

[0008] Optionally, the second supplementary lighting member has an arc-shaped plate structure, which protrudes towards the direction close to the corresponding attachment cylinder, its arc trajectory is perpendicular to the rotation axis of the corresponding attachment cylinder, and it emits light radially towards the bottom of the corresponding attachment cylinder with the axis of its own arc trajectory as the axis.

[0009] By adopting the above technical solutions, it can improve the effect of the second supplementary lighting member in supplementing light for the fouling-resistant algae, and at the same time, after the metabolites during the growth process of the fouling-resistant algae fall onto the second supplementary lighting member, it can smoothly guide them to fall and finally discharge them through the sewage outlet.

[0010] Optionally, a plurality of soft bristles are arranged on the outer side of the attachment cylinder, and the bristles located at the bottom of the attachment cylinder are in contact with the corresponding second supplementary lighting member.

[0011] By adopting the above technical solution, during the rotation of the attachment cylinder, the corresponding second supplementary lighting member can be cleaned by the bristles, thereby effectively reducing the probability that the supplementary lighting effect is affected due to the pollution of the second supplementary lighting member by the metabolites of pollution-resistant algae.

[0012] Optionally, a plurality of reflectors are provided on the inner walls of both sides of the top of the ecological cage in the ecological space, and the reflecting surfaces of the reflectors are inclined upward toward the direction close to the adjacent attachment cylinder.

[0013] By adopting the above technical solution, the reflectors can effectively improve the utilization rate of natural light and the supplementary light of the supplementary lighting component by pollution-resistant algae, thereby further improving the effect of pollution-resistant algae absorbing light, and further improving the activity of pollution-resistant algae; at the same time, it can effectively reduce the probability that the light diffuses under the sea surface at night during the process of the supplementary lighting component supplementing light to pollution-resistant algae, attracting fish and causing the number of pollution-resistant algae to decrease due to being preyed on.

[0014] Optionally, the floating assembly further includes a frame body and two light-shielding plates; The frame body is arranged on the top of the floating plate, close to the light inlet and above the ecological space; the light-shielding plates are movably installed on the top of the frame body; when both light-shielding plates move away from the frame body to the extreme positions, the pollution-resistant algae in the ecological space receive natural light through the light inlet; when both light-shielding plates move toward the frame body to the extreme positions, the light-shielding plates shield light above the light inlet.

[0015] By adopting the above technical solution, the light-shielding plates can prevent the light from diffusing outward above the sea surface during the process of the supplementary lighting component supplementing light to pollution-resistant algae at night, reducing the impact of light on ships, and at the same time reducing the probability that the light attracts seabirds and affects pollution-resistant algae.

[0016] Optionally, a bottom plate and a second driving member are movably arranged on the ecological cage along the vertical direction; The second driving member is electrically connected to the energy supply member, is arranged on the floating plate, and is used to drive the bottom plate to move; when the bottom plate moves toward the ecological cage to the extreme position, the bottom plate closes the opening at the bottom of the ecological space; when the bottom plate moves away from the ecological cage to the extreme position, a sewage outlet is formed between the bottom plate and the ecological cage.

[0017] By adopting the above technical solution, during the process of the supplementary lighting component supplementing light to pollution-resistant algae at night, the bottom plate can close the opening at the bottom of the ecological space, thereby further reducing the probability that fish are attracted by light and approach, resulting in the pollution-resistant algae being preyed on.

[0018] Optionally, the supplementary light component is signal - connected to the second driving member. After the supplementary light component operates, the second driving member drives the bottom plate to move towards the ecological cage to the extreme position, and both the light - shielding plates move towards the frame to the extreme position accordingly.

[0019] By adopting the above - mentioned technical solution, it is possible to facilitate the movement of the bottom plate and the light - shielding plates according to the usage state of the supplementary light component, and realize the automatic switching of different lighting forms.

[0020] Optionally, the top of the bottom plate has two guiding surfaces. The two guiding surfaces are respectively close to both sides of the bottom plate and are symmetrically distributed on the bottom plate, and the guiding surfaces are used to guide substances to leave through the sewage outlet; A plurality of diversion holes are also formed in the bottom plate, and the plurality of diversion holes are symmetrically distributed on the bottom plate; one end of the diversion hole penetrates through the adjacent guiding surface to form an opening and the other end penetrates through the bottom of the bottom plate to form an opening, and the diversion hole is inclined upward towards the corresponding guiding surface.

[0021] By adopting the above - mentioned technical solution, it is possible to facilitate the discharge of impurities such as the metabolites of pollution - tolerant algae falling above the bottom plate through the sewage outlet. And during the downward movement of the bottom plate, seawater can flow through the diversion holes to wash the guiding surfaces, further facilitating the discharge of impurities.

[0022] Optionally, a number of impellers are rotatably arranged in the diversion holes of the bottom plate. The impellers are rotatably connected to the bottom plate, and the rotation axis thereof is perpendicular to the opening direction of the diversion holes.

[0023] By adopting the above - mentioned technical solution, it is possible to prevent fish from passing through the bottom plate through the diversion holes, and at the same time effectively reduce the probability of the diversion holes being blocked by impurities.

[0024] On the other hand, the present application provides a marine restoration method, adopting the following technical solution: A marine restoration method, based on the above - mentioned ecological restoration device, includes the following steps: S1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will further describe the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0030] Example 1: This embodiment of the present application discloses a marine restoration method. Utilizing the characteristics that pollution-resistant algae can absorb nitrogen and phosphorus organic pollutants such as urea, amino acids, and phosphate esters, as well as refractory and toxic substances such as lignin and phenols, and can even adsorb heavy metals, it is used for ecological restoration of marine polluted areas, including the following steps: S1. Construct an ecological restoration device in the marine polluted area.

[0031] Construct an ecological restoration device that can float on the sea surface in the polluted area of the sea to form a place for cultivating a certain number of pollution-resistant algae.

[0032] S2. Inoculate pollution-resistant algae into the ecological restoration device, and introduce a bacterial community for decomposing pollutants and plankton for controlling the competing organisms of the pollution-resistant algae into the ecological restoration device.

[0033] Inoculate a certain number of pollution-resistant algae into the ecological restoration device for cultivation, and at the same time introduce specific bacterial communities and plankton into the ecological restoration device; The bacterial community is a degrading bacterium (such as a petroleum-degrading bacterium). The bacterial community can decompose pollutants to provide a carbon source for the pollution-resistant algae. At the same time, the oxygen released during the growth process of the pollution-resistant algae can also promote the aerobic metabolism of the bacterial community; Plankton (such as copepods) can effectively control the number of competing organisms (such as harmful algae) of the pollution-resistant algae, thereby maintaining the growth advantage of the pollution-resistant algae and ensuring the quantity and activity of the pollution-resistant algae.

[0034] S3. Input the nutrients required for the growth of pollution-resistant algae into the ecological restoration device and conduct reasonable regulation.

[0035] Input a certain amount of nutrients for the pollution-resistant algae, such as nitrogen (nitrate), phosphorus (phosphate), and iron (Fe²⁺ / Fe³⁺), etc., to promote the growth of the pollution-resistant algae. In practical applications, the supplement of nutrients can be specifically analyzed according to the situation of the sea.

[0036] It is also possible to input a slow-release fertilizer with a degradable coating (such as urea-formaldehyde polymer). While providing the nutrients required for the growth of the pollution-resistant algae, it can also control the release rate of the nutrients in the sea, avoiding algal blooms or waste caused by short-term nutrient surplus.

[0037] S4. Provide sufficient light for the pollution-resistant algae.

[0038] Increase the light transmittance through artificial floating islands or surface suspension devices, or supplement LED light sources (specific wavelengths such as red light and blue light) in the upper layer of the water body to provide sufficient light for the growth of the pollution-resistant algae, so that the pollution-resistant algae can grow rapidly and maintain their activity.

[0039] Example 2: Referring to Figure 1 and Figure 2 , an ecological restoration device is disclosed in an embodiment of the present application, which is used in an ocean restoration method disclosed in Example 1 to perform ecological restoration of ocean pollution through pollution-tolerant algae.

[0040] Referring to Figure 1 and Figure 3 , the ecological restoration device includes a floating component 1, an attachment component 2, a light supplement component 3, and an energy supply component 4. Among them, the floating component 1 is used to make the ecological restoration device float on the sea surface; the attachment component 2 provides a place for the growth and cultivation of pollution-tolerant algae; the light supplement component 3 supplements light for the pollution-tolerant algae, so that the pollution-tolerant algae can fully absorb light, which helps the growth of the pollution-tolerant algae and ensures the activity of the pollution-tolerant algae; the energy supply component 4 can supply energy to the floating component 1, the attachment component 2, and the light supplement component 3.

[0041] The floating component 1 includes a floating board 11, an ecological cage 12, a frame body 14, two light-shielding plates 15, a bottom plate 13, and a second driving member 16.

[0042] The floating board 11 is in an overall rectangular plate structure and can float on the sea surface. In this embodiment, since the floating board 11 with the above functions is a prior art in the field, it will not be described in detail here; in actual application, the floating board 11 will be connected to a heavy object sunk to the bottom of the sea by a rope, so that the top of the floating board 11 can be kept above the sea surface, and at the same time, the position stability of the floating board 11 on the sea surface is improved.

[0043] The ecological cage 12 is in an overall cuboid structure, which is fixedly installed at the bottom of the floating board 11, and has an ecological space 121 in the shape of a cuboid for the cultivation and growth of pollution-tolerant algae inside; openings are formed at the top and bottom of the ecological space 121 along the vertical direction through the ecological cage 12. Correspondingly, a light inlet 111 communicating with the ecological space 121 is formed through the floating board 11 along the vertical direction to allow natural light to enter the ecological space 121. In this embodiment, it is preferably that the length direction of the floating board 11, the length direction of the ecological cage 12, and the length direction of the ecological space 121 are parallel to each other, and the width direction of the floating board 11, the width direction of the ecological cage 12, and the width direction of the ecological space 121 are also parallel to each other; and it is preferably that the cross-sectional size of the light inlet 111 is the same as the cross-sectional size of the opening above the ecological space 121.

[0044] Referring to Figure 3 and Figure 4, the bottom plate 13 is installed at the bottom of the ecological cage 12, and is movably connected to the ecological cage 12, and its moving direction is parallel to the height direction of the ecological cage 12. There are restrictions during the movement of the bottom plate 13 relative to the ecological cage 12; when the bottom plate 13 moves towards the ecological cage 12 to the extreme position, the bottom plate 13 closes the opening below the ecological space 121; when the bottom plate 13 moves away from the ecological cage 12 to the extreme position, a sewage outlet 122 for communicating the ecological space 121 with the space below the sea surface will be formed between the bottom and the ecological space 121, for impurities such as metabolites generated during the growth of pollution-tolerant algae to leave the ecological space 121.

[0045] Refer to Figure 2 and Figure 4 , the second driving member 16 is fixedly installed on the top of the floating plate 11, and is used to drive the bottom plate 13 to move relative to the ecological cage 12. In this embodiment, preferably, the second driving member 16 is a servo motor, which is used to drive the gear to rotate. An extension rod extending upward is provided on the bottom plate 13 and is in threaded cooperation with the floating plate 11. A rack structure meshing with the gear is provided on the extension rod along its length direction. The second driving member 16 drives the bottom plate 13 to move relative to the ecological cage 12 through the meshing of the gear and the rack; since the above-mentioned manner of driving the bottom plate 13 by the second driving member 16 is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0046] Refer to Figure 3 and Figure 4 , the top of the bottom plate 13 has two guiding surfaces 131 for guiding impurities to leave through the sewage outlet 122. The two guiding surfaces 131 are symmetrically distributed on the bottom plate 13 and are respectively close to both ends of the length direction of the bottom plate 13. In this embodiment, preferably, the guiding surface 131 is an inclined surface, and preferably, the inclined upper ends of the two guiding surfaces 131 are connected.

[0047] At this time, when the bottom plate 13 moves away from the ecological cage 12 to the extreme position, the impurities falling on the bottom plate 13 can move towards the sewage outlet 122 under the guidance of the guiding surface 131.

[0048] Furthermore, preferably, a plurality of diversion holes 132 for seawater to flow through the bottom plate 13 are also provided on the bottom plate 13.

[0049] The opening direction of the diversion holes 132 on the bottom plate 13 is inclined relative to the thickness direction of the bottom plate 13. One end of the diversion hole 132 penetrates through the position close to its inclined upper end of the guiding surface 131 to form an opening, and the other end of the diversion hole 132 is inclined downward towards the center position of the bottom plate 13 and penetrates through the bottom of the bottom plate 13 to form an opening.

[0050] At this time, during the process of the bottom plate 13 moving away from the ecological cage 12 to the extreme position, the seawater below the bottom plate 13 will pass through the bottom plate 13 through the diversion holes 132, and then flow along the corresponding guiding surfaces 131 towards the adjacent sewage outlets 122, so as to be able to wash the guiding surfaces 131, and further facilitate the discharge of impurities falling on the top of the bottom plate 13.

[0051] Furthermore, preferably, a plurality of impellers 133 are rotatably installed on the bottom plate 13.

[0052] The impeller 133 is integrally in a cylindrical structure, which is located in the diversion hole 132, and its rotation axis coincides with its own axis and is parallel to the width direction of the bottom plate 13.

[0053] At this time, the impeller 133 in the diversion hole 132 can effectively prevent small fish in the ocean from entering the ecological space 121 through the diversion hole 132 to prey on pollution-tolerant algae; and when seawater flows through the diversion hole 132, it can drive the impeller 133 to rotate relative to the bottom plate 13, thereby effectively reducing the probability of the diversion hole 132 being blocked by impurities.

[0054] Refer to Figure 1 and Figure 3 , the frame body 14 is integrally in a cuboid frame structure, which is fixedly installed on the top of the floating plate and is located above the light inlet 111. In this embodiment, preferably, the length direction of the frame body 14 is parallel to the length direction of the floating plate 11, and the width direction of the frame body 14 is parallel to the width direction of the floating plate 11; and preferably, the length dimension and width dimension of the frame body 14 respectively match the length dimension and width dimension of the light inlet 111.

[0055] The light-shielding plate 15 is integrally in a rectangular plate structure, which is movably installed on the top of the frame body 14, and its moving direction is parallel to the length direction of the frame body 14. In this embodiment, preferably, the length direction of the light-shielding plate 15 is parallel to the length direction of the frame body 14, and the width direction of the light-shielding plate 15 is parallel to the width direction of the frame body 14.

[0056] Refer to Figure 1 and Figure 2 , there are limitations during the process of the light-shielding plate 15 moving relative to the frame body 14; when both light-shielding plates 15 move towards the direction close to the frame body 14 to the extreme position, the two light-shielding plates 15 can jointly form a shield above the light inlet 111; when both light-shielding plates 15 move towards the direction away from the frame body 14 to the extreme position, the two light-shielding plates 15 will be respectively located on both sides of the length direction of the frame body 14, and at this time, natural light can smoothly pass through the light inlet 111 and shine into the ecological space 121.

[0057] Refer to Figure 3 and Figure 4, Further, preferably, during the movement of the bottom plate 13 relative to the ecological cage 12, the two light-shielding plates 15 can be driven to move relative to the frame 14. During the process of the bottom plate 13 moving towards the ecological cage 12 to the extreme position, the two light-shielding plates 15 will both move towards the frame 14 to the extreme position; during the process of the bottom plate 13 moving away from the ecological cage 12 to the extreme position, the two light-shielding plates 15 will both move away from the frame 14 to the extreme position. In this embodiment, preferably, the light-shielding plate 15 also has a rack structure along its own length direction, and preferably, two extension rods extend upward from the bottom plate 13, and the two extension rods correspond to the two light-shielding plates 15 one by one; a gear for meshing with the corresponding extension rod and light-shielding plate 15 is rotatably installed on the frame 14, and the gear and the rack are meshed to form a linkage between the bottom plate 13 and the light-shielding plate 15, and the movements of the two light-shielding plates 15 are synchronous and opposite; since the above-mentioned linkage method of the bottom plate 13 and the light-shielding plate 15 is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0058] Referring to Figure 1 and Figure 3 , the attachment assembly 2 includes a plurality of attachment cylinders 21 for the fouling algae to attach and grow and a first driving member 22 for driving the attachment cylinders 21 to move to change the position of the fouling algae.

[0059] The attachment cylinder 21 is integrally in a cylindrical structure, and its outer side has a structure for the fouling algae to attach and grow. It is installed in the ecological space 121 and is rotatably connected to the ecological cage 12. Its rotation axis coincides with its own axis and is parallel to the width direction of the ecological cage 12; a plurality of attachment cylinders 21 are equidistantly distributed on the ecological cage 12 along the length direction of the ecological cage 12, and a structure for making the plurality of attachment cylinders 21 rotate in the same direction and synchronously is installed on the ecological cage 12. In this embodiment, preferably, the plurality of attachment cylinders 21 achieve the effect of rotating in the same direction and synchronously through a synchronous belt structure; since the synchronous belt structure is a common prior art, it will not be elaborated here, and it is omitted in the drawings.

[0060] The first driving member 22 is fixedly installed on the top of the floating plate 11 and is used to drive the plurality of attachment cylinders 21 to rotate synchronously and in the same direction relative to the ecological cage 12. In this embodiment, preferably, the first driving member 22 is a servo motor, which directly drives the adjacent attachment cylinder 21 to rotate, and preferably, the first driving member 22 achieves the effect of driving the attachment cylinder 21 to rotate through a synchronous belt structure; since both the servo motor and the synchronous belt structure are common prior arts, they will not be elaborated here, and they are only briefly shown in the drawings.

[0061] Referring to Figure 3 and Figure 4 , the supplementary lighting assembly 3 includes a plurality of first supplementary lighting members 31 and a plurality of second supplementary lighting members 32 corresponding to the plurality of attachment cylinders 21 one by one.

[0062] The first supplementary lighting member 31 is fixedly installed inside the corresponding attachment cylinder 21. It can emit light outward with the axis of the attachment cylinder 21 as the axis, and the inner structure of the attachment cylinder 21 is designed to be light-transmissive, so that the pollution-resistant algae growing on the attachment cylinder 21 can absorb the supplementary light provided by the first supplementary lighting member 31. In this embodiment, since the first supplementary lighting member 31 and the attachment cylinder 21 with the above functions are common prior arts, they will not be elaborated here, and only a brief representation is shown in the drawings.

[0063] The second supplementary lighting member 32 is integrally in an arc-shaped plate structure. It is fixedly installed on the ecological cage 12 and is located in the ecological space 121. It is located below the corresponding attachment cylinder 21 and is vertically aligned with the corresponding attachment cylinder 21; the arc structure of the second supplementary lighting member 32 protrudes towards the direction close to the corresponding attachment cylinder 21, and the arc trajectory of the second supplementary lighting member 32 is perpendicular to the axis of the corresponding attachment cylinder 21.

[0064] The second supplementary lighting member 32 can provide supplementary light radially towards the direction close to the corresponding attachment cylinder 21 with the axis of its arc trajectory as the axis, so that the pollution-resistant algae attached to the bottom of the attachment cylinder 21 can fully absorb light; at the same time, after impurities such as metabolites in the growth process of the pollution-resistant algae on the attachment cylinder 21 fall onto the corresponding second supplementary lighting member 32, they can slide along the arc surface of the second supplementary lighting member 32 and finally be discharged through the sewage outlet 122.

[0065] Furthermore, in order to further reduce the influence of impurities falling on the surface of the second supplementary lighting member 32 and ensure the supplementary lighting effect of the second supplementary lighting member 32 on the pollution-resistant algae, it is preferred that a plurality of soft bristles 211 are evenly distributed on the outer side of the attachment cylinder 21.

[0066] During the rotation of the attachment cylinder 21 relative to the ecological cage 12, the bristles 211 close to the corresponding second supplementary lighting member 32 can contact and abut against the arc surface of the second supplementary lighting member 32, so as to clean the arc surface of the second supplementary lighting member 32 and further reduce the probability of impurities staying on the surface of the second supplementary lighting member 32.

[0067] Furthermore, in order to further improve the utilization rate of natural light and the supplementary light of the supplementary lighting assembly 3 by the pollution-resistant algae, it is preferred that a plurality of reflectors 5 are installed on the inner walls of both sides of the ecological cage 12 in the length direction of the ecological space 121.

[0068] The reflecting surface of the reflector 5 is inclined upward towards the direction close to the center position of the ecological space 121, and can reflect the natural light and supplementary light it receives and reflect the light to the adjacent attachment cylinder 21. In this embodiment, since the reflector 5 with the above functions is a common prior art, it will not be elaborated here, and only a brief representation is shown in the drawings.

[0069] Refer toFigure 1 and Figure 3 , the energy supply component 4 includes a plurality of solar panels 41 and an energy supply member 42.

In this embodiment, preferably, the solar panels 41 can absorb natural light to generate energy; since the solar panels 41 with the above functions are common prior arts, they will not be elaborated here, and they are only briefly shown in the drawings.

[0071] The energy supply member 42 is fixedly installed on the top of the floating plate 11, and is electrically connected to a plurality of solar panels 41 at the same time, and the plurality of solar panels can supply energy to it at the same time; the energy supply member 42 is also electrically connected to the first driving member 22, the second driving member 16, a plurality of first supplementary lighting members 31 and a plurality of second supplementary lighting members 32 at the same time to supply energy to them.

[0072] Referring to Figure 2 and Figure 4 , the energy supply member 42 is also signal-connected to a plurality of solar panels 41, a plurality of first supplementary lighting members 31 and a plurality of second supplementary lighting members 32 at the same time. When the energy supply from the solar panels 41 to the energy supply member 42 decreases to a certain value (i.e., on cloudy days or at night), the energy supply member 42 will control the plurality of first supplementary lighting members 31 and the plurality of second supplementary lighting members 32 to supplement light to the pollution-resistant algae, so that the supplementary lighting component 3 can supplement light to the pollution-resistant algae in time when the natural light conditions are insufficient; and, during the process of the supplementary lighting component 3 supplementing light to the pollution-resistant algae, it can improve the temperature of the environment around the pollution-resistant algae to a certain extent, making the temperature conditions more suitable for the growth and maintenance of the activity of the pollution-resistant algae. In this embodiment, since the energy supply member 42 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0073] Referring to Figure 1 and Figure 3 , further, preferably, the second driving member 16 is signal-connected to the supplementary lighting component 3. When the supplementary lighting component 3 is in the standby state, the second driving member 16 will drive the bottom plate 13 to move away from the ecological cage 12 to the extreme position and stay, and at the same time, the two light-shielding plates 15 will move away from the frame 14 to the extreme position and stay, facilitating the pollution-resistant algae to absorb natural light; Referring to Figure 2 and Figure 4, when the supplementary lighting component 3 is in an operating state, the second driving member 16 will drive the bottom plate 13 to move towards the ecological cage 12 to the extreme position and stay, and at the same time, the two light-shielding plates 15 will move towards the frame 14 to the extreme position and stay. At this time, both the bottom plate 13 and the two light-shielding plates 15 can prevent the supplementary light from diffusing outwards, thereby effectively reducing the probability that the supplementary light misleads ships, attracts birds and fish to approach and prey on the pollution-resistant algae.

[0074] Referring to Figure 1 and Figure 3 , further preferably, when the two light-shielding members move to the extreme position away from the frame 14, the two light-shielding members can form two light-shielding areas above the floating plate 11; and preferably, a plurality of solar panels 41 are installed at positions on the floating plate 11 outside the light-shielding areas, while the power supply member 42, the first driving member 22 and the second driving member 16 are all installed at positions on the floating plate 11 inside the light-shielding areas. This enables the solar panels 41 to stably achieve the effect of absorbing natural light for power supply, while effectively reducing the influence of natural light on the power supply member 42, the first driving member 22 and the second driving member 16, and extending the service life of the power supply member 42, the first driving member 22 and the second driving member 16.

[0075] The implementation principle of an ecological restoration device according to an embodiment of the present application is as follows: During the process of the pollution-resistant algae attaching and growing on the attaching cylinder 21, the first driving member 22 will drive the plurality of attaching cylinders 21 to keep rotating, making the lighting effect received by the pollution-resistant algae more uniform, improving the activity of the pollution-resistant algae, and contributing to the growth of the pollution-resistant algae; Generally, the pollution-resistant algae will receive natural light during the day. When there is insufficient natural light (such as on cloudy days or at night), the supplementary lighting component 3 will operate to supplement light for the pollution-resistant algae, so that the pollution-resistant algae can still fully absorb light, maintain growth and maintain a high activity; By cultivating and growing a certain amount of pollution-resistant algae and keeping it highly active, the ecological restoration of the marine pollution area can be carried out.

[0076] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
