Description

Technical Field

[0001] The present application relates to the technical field of marine ecological restoration, and in particular to an ecological restoration device and a marine restoration method. Background Art

[0002] Through their adsorption, metabolism, and ecological restoration capabilities, pollution-tolerant algae offer a low-cost, sustainable solution for marine pollution remediation. When organic matter concentrations in water are too high, these algae can absorb nitrogen- and phosphorus-containing organic pollutants like urea, amino acids, and phosphates, as well as persistent and toxic substances like lignin and phenols. They can even absorb heavy metals. These properties make their use as a promising technology for remediating offshore marine waters.

[0003] In the method of using pollution-tolerant algae to repair the ocean, it is usually necessary to set up attachment beds. The core purpose is to optimize its growth environment through artificial intervention and create an "artificial ecological niche". Through physical stabilization, spatial orientation and community regulation, it breaks through the limitations of the natural environment, maximizes its restoration potential, and improves the pollution-tolerant algae's repair efficiency and ecological stability for pollutants.

[0004] However, in the existing pollution-resistant algae attachment beds, multiple attachment substrates for pollution-resistant algae to attach are usually stacked up and down, and the positions of the attachment substrates remain basically fixed. This can easily affect the effect of the pollution-resistant algae on the attachment substrate below on receiving light, thereby affecting the normal growth of the pollution-resistant algae, and further affecting the effect of marine ecological restoration. Summary of the Invention

[0005] The present application provides an ecological restoration device and a marine restoration method, which can effectively improve the effect of pollution-resistant algae receiving light, thereby enabling the pollution-resistant algae to remain active, and further improving the effect of marine ecological restoration.

[0006] On the one hand, the present application provides an ecological restoration device, which adopts the following technical solutions:

[0007] An ecological restoration device includes a floating component, an attachment component, a light-filling component, and an energy supply component;

[0008] The floating assembly includes a floating board and an ecological cage; the floating board floats on the sea surface, and 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 light port for connecting the ecological space with the space on the sea, and the bottom of the ecological cage has a sewage outlet connected to the ecological space.

[0009] The attachment assembly includes a plurality of attachment tubes and a first driving member; the outer side of the attachment tubes is for the pollution-tolerant algae to attach and grow, and the attachment tubes are arranged in the ecological space and are rotatably connected to the ecological cage, and the rotation axes of the plurality of attachment tubes are parallel to each other; the first driving member is arranged on the top of the floating board, and is used to drive the plurality of attachment tubes to rotate synchronously and in the same direction;

[0010] The fill light assembly includes a plurality of first fill light members and a plurality of second fill light members corresponding to the plurality of attachment tubes one by one; the first fill light members are arranged inside the corresponding attachment tubes, and fill light outwards while the attachment tubes are light-transmissive; the second fill light members are arranged in the ecological space and below the corresponding attachment tubes, and fill light upwards;

[0011] The energy supply component includes multiple solar panels and energy supply components; the solar panels are arranged on the top of the floating board, the solar panels are electrically connected to the energy supply components, and the energy supply components are also electrically connected to the first driving component and the fill light component; the energy supply components are signal-connected to the solar panels and the fill light component, and when the energy supply of the solar panels is lower than a certain value, the energy supply components control the operation of the fill light component.

[0012] By adopting the above technical solution, when the lighting conditions are sufficient, the continuously rotating attachment tube can enable the pollution-resistant algae attached to its outside to evenly absorb sunlight, thereby effectively improving the growth efficiency of the pollution-resistant algae; when the lighting conditions are insufficient, the fill light component can temporarily supplement the lighting conditions for the pollution-resistant algae to effectively ensure the vitality of the pollution-resistant algae. At the same time, the fill light component can increase the temperature of the environment surrounding the pollution-resistant algae to a certain extent during the night-time fill light process, so that the pollution-resistant algae can grow in a more suitable temperature environment, thereby further improving the effect of marine ecological restoration.

[0013] Optionally, the second fill light is an arc-shaped plate structure, which protrudes toward the direction close to the corresponding attachment tube, its arc trajectory is perpendicular to the rotation axis of the corresponding attachment tube, and it radially fills light toward the bottom of the corresponding attachment tube with the axis of its own arc trajectory as the axis.

[0014] By adopting the above technical solution, the effect of the second fill light component on supplementary lighting of the pollution-resistant algae can be improved, and at the same time, the metabolic products of the pollution-resistant algae during their growth process can be smoothly guided to fall after falling on the second fill light component and finally discharged through the sewage outlet.

[0015] Optionally, a plurality of soft bristles are provided on the outer side of the attachment tube, and the bristles located at the bottom of the attachment tube are in contact with the corresponding second fill light component.

[0017] Optionally, the ecological cage is provided with a plurality of reflectors on the inner walls on both sides of the top of the ecological space, and the reflective surfaces of the reflectors are inclined upward toward the direction close to the adjacent attachment tube.

[0018] By adopting the above-mentioned technical solution, the reflector can effectively improve the utilization rate of natural light and supplementary light from the fill light component by the pollution-resistant algae, thereby further improving the effect of the pollution-resistant algae in absorbing light, and further improving the activity of the pollution-resistant algae; at the same time, it can effectively reduce the probability that the light diffuses below the sea surface during the process of the fill light component supplementing the pollution-resistant algae at night, attracting fish, resulting in the pollution-resistant algae being preyed on and the number decreasing.

[0019] Optionally, the floating assembly further includes a frame and two sunshades;

[0020] The frame is arranged on the top of the floating board, close to the light port and located above the ecological space; the sunshade is movably installed on the top of the frame; when both of the sunshades are moved to the extreme position in the direction away from the frame, the pollution-resistant algae in the ecological space receive natural light through the light port; when both of the sunshades are moved to the extreme position in the direction close to the frame, the sunshades block light above the light port.

[0021] By adopting the above technical solution, the sunshade can prevent light from diffusing outward on the sea surface when the fill light component supplements the light for the pollution-resistant algae at night, thereby reducing the impact of light on the ship and reducing the probability of light attracting seabirds and affecting the pollution-resistant algae.

[0022] Optionally, a bottom plate and a second driving member are movably provided on the ecological cage in a vertical direction;

[0023] The second driving member is electrically connected to the energy supply member, is arranged on the floating board, and is used to drive the bottom plate to move; when the bottom plate moves to the extreme position in the direction close to the ecological cage, the bottom plate closes the opening at the bottom of the ecological space; when the bottom plate moves to the extreme position in the direction away from the ecological cage, the sewage outlet is formed between the bottom plate and the ecological cage.

[0024] By adopting the above technical solution, when the supplementary light component supplements the light for the pollution-resistant algae at night, the bottom plate can close the opening at the bottom of the ecological space, thereby further reducing the probability of fish being attracted by the light and approaching, resulting in the pollution-resistant algae being preyed upon.

[0025] Optionally, the fill light component is connected to the second driving component signal. After the fill light component is running, the second driving component drives the bottom plate to move toward the ecological cage to the extreme position, and the two sunshades also move toward the frame to the extreme position.

[0027] Optionally, the top of the bottom plate has two guide surfaces, the two guide surfaces are respectively close to the two sides of the bottom plate and symmetrically distributed on the bottom plate, and the guide surfaces are used to guide the material to leave through the sewage outlet;

[0028] The bottom plate is also provided with a plurality of guide holes, and the plurality of guide holes are symmetrically distributed on the bottom plate; one end of the guide hole passes through the adjacent guide surface to form an opening and the other end passes through the bottom of the bottom plate to form an opening, and the guide hole is opened inclined upward in the direction close to the corresponding guide surface.

[0029] By adopting the above technical solution, impurities such as the metabolic products of the pollution-resistant algae that fall above the bottom plate can be easily discharged through the sewage outlet, and in the process of the bottom plate moving downward, seawater can flow through the diversion holes to flush the guide surface, further facilitating the discharge of impurities.

[0030] Optionally, the bottom plate is further rotatably provided with a plurality of impellers in the guide hole, the impellers are rotatably connected to the bottom plate, and the rotation axes thereof are perpendicular to the opening direction of the guide hole.

[0050] The following is combined with Figure 1-4 This application is described in further detail.

[0051] Example 1:

[0052] The present invention discloses a method for marine restoration, which utilizes the ability of pollution-tolerant algae to absorb nitrogen- and phosphorus-containing organic pollutants such as urea, amino acids, and phosphates, as well as difficult-to-degrade and toxic substances such as lignin and phenols, and even heavy metals, to perform ecological restoration of polluted marine areas. The method comprises the following steps:

[0053] S1. Construct ecological restoration equipment in marine polluted areas.

[0054] An ecological restoration device that can float on the sea surface is constructed in the polluted area of ​​the ocean to form a place for cultivating a certain number of pollution-resistant algae.

[0055] S2. Inoculating pollution-tolerant algae into the ecological restoration device, and introducing bacterial communities for decomposing pollutants and plankton for controlling competing organisms of the pollution-tolerant algae into the ecological restoration device.

[0056] A certain amount of pollution-resistant algae is inoculated into the ecological restoration device for cultivation, and specific bacterial communities and plankton are introduced into the ecological restoration device at the same time;

[0057] The bacterial community is a degrading bacteria (such as oil-degrading bacteria). The bacterial community can decompose pollutants and provide a carbon source for pollution-tolerant algae. At the same time, the oxygen released during the growth of pollution-tolerant algae can also promote the aerobic metabolism of the bacterial community.

[0058] Plankton (such as copepods) can effectively control the number of competing organisms of pollution-resistant algae (such as harmful algae), thereby maintaining the growth advantage of pollution-resistant algae and ensuring the number and activity of pollution-resistant algae.

[0059] S3. Add nutrients required for the growth of pollution-tolerant algae into the ecological restoration device and perform reasonable regulation.

[0060] A certain amount of nutrients, such as nitrogen (nitrate), phosphorus (phosphate), and iron (Fe²⁺ / Fe³⁺), are added to the pollution-tolerant algae to promote their growth. In practice, nutrient supplementation can be tailored to specific ocean conditions.

[0061] Slow-release fertilizers with degradable coatings (such as urea-formaldehyde polymers) can also be added to provide the nutrients needed for the growth of pollution-tolerant algae, while also controlling the rate at which nutrients are released into the ocean, avoiding short-term excess nutrients that lead to algal blooms or waste.

[0062] S4. Provide sufficient light for pollution-tolerant algae.

[0063] By increasing light transmittance through artificial floating islands or surface suspended devices, or supplementing LED light sources (specific wavelengths such as red light and blue light) in the upper layer of the water body, sufficient light is provided for the growth of pollution-resistant algae, allowing them to grow rapidly and remain active.

[0064] Example 2:

[0065] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an ecological restoration device, which is used in a marine restoration method disclosed in Example 1 to perform ecological restoration of marine pollution through pollution-resistant algae.

[0066] Reference Figure 1 and Figure 3 The ecological restoration device includes a floating component 1, an attachment component 2, a supplemental light component 3, and an energy supply component 4. The floating component 1 is used to keep the ecological restoration device afloat; the attachment component 2 provides a growth and cultivation environment for pollution-tolerant algae; the supplemental light component 3 provides additional light for the pollution-tolerant algae, allowing them to fully absorb light, thereby promoting their growth and ensuring their activity; and the energy supply component 4 provides energy for the floating component 1, the attachment component 2, and the supplemental light component 3.

[0067] The floating assembly 1 includes a floating board 11 , an ecological cage 12 , a frame 14 , two sunshades 15 , a bottom plate 13 and a second driving member 16 .

[0068] The floating board 11 is a rectangular plate-shaped structure that can float on the sea surface. In this embodiment, since the floating board 11 with the above-mentioned functions is existing in the art, its details will not be described in detail here. In actual application, the floating board 11 will be connected to a heavy object sunk to the seabed via a rope, so that the top of the floating board 11 can remain above the sea surface, while also improving the positional stability of the floating board 11 on the sea surface.

[0069] The ecological cage 12 is an overall rectangular parallelepiped structure, fixedly mounted to the bottom of the floating board 11. It contains a rectangular parallelepiped ecological space 121 for the cultivation and growth of pollution-tolerant algae. The ecological space 121 vertically extends through the top and bottom of the ecological cage 12, with openings formed therein. Correspondingly, a light port 111 is vertically extended through the floating board 11, communicating with the ecological space 121, allowing natural light to enter the ecological space 121. In this embodiment, the length of the floating board 11, the length of the ecological cage 12, and the length of the ecological space 121 are preferably parallel to each other, and the width of the floating board 11, the width of the ecological cage 12, and the width of the ecological space 121 are also parallel to each other. Furthermore, the cross-sectional dimensions of the light port 111 are preferably the same as the cross-sectional dimensions of the opening above the ecological space 121.

[0070] Reference Figure 3 and Figure 4 Bottom plate 13 is mounted on the bottom of ecological cage 12 and is movably connected to ecological cage 12, with its movement direction parallel to the height direction of ecological cage 12. Bottom plate 13 is restricted in its movement relative to ecological cage 12. When bottom plate 13 moves to its limit position toward ecological cage 12, it closes the opening below ecological space 121. When bottom plate 13 moves to its limit position away from ecological cage 12, a sewage outlet 122 is formed between the bottom and ecological space 121, connecting ecological space 121 with the space below the sea surface. This allows impurities such as metabolic products produced during the growth of pollution-tolerant algae to leave ecological space 121.

[0071] Reference Figure 2 and Figure 4 The second drive member 16 is fixedly mounted on the top of the floating board 11 and is used to drive the bottom board 13 to move relative to the ecological cage 12. In this embodiment, the second drive member 16 is preferably a servo motor, which is used to drive the gear to rotate. An extension rod extends upward from the bottom board 13 and is connected to the floating board 11. The extension rod has a rack structure along its length that meshes with the gear. The second drive member 16 drives the bottom board 13 relative to the ecological cage 12 through the meshing of the gear and the rack. Since the method of the second drive member 16 driving the bottom board 13 is common in the prior art, it will not be described in detail here, and it is only briefly illustrated in the drawings.

[0072] Reference Figure 3 and Figure 4 The top of the bottom plate 13 has two guide surfaces 131 for guiding impurities to exit through the sewage outlet 122. The two guide surfaces 131 are symmetrically distributed on the bottom plate 13 and are respectively close to the two ends of the length direction of the bottom plate 13. In this embodiment, the guide surfaces 131 are preferably inclined surfaces, and the inclined upper ends of the two guide surfaces 131 are preferably connected.

[0073] At this time, when the bottom plate 13 moves to the extreme position in the direction away from the ecological cage 12 , the impurities that fall onto the bottom plate 13 can move toward the direction close to the sewage outlet 122 under the guidance of the guide surface 131 .

[0074] Furthermore, it is preferred that a plurality of guide holes 132 are provided on the bottom plate 13 for allowing seawater to flow through the bottom plate 13 .

[0075] The direction in which the guide hole 132 is opened on the bottom plate 13 is inclined relative to the thickness direction of the bottom plate 13. One end of the guide hole 132 passes through the guide surface 131 near its own inclined upper end to form an opening, and the other end of the guide hole 132 is inclined downward toward the center position of the bottom plate 13 to pass through the bottom of the bottom plate 13 to form an opening.

[0076] At this time, when the bottom plate 13 moves to the extreme position in the direction away from the ecological cage 12, the seawater below the bottom plate 13 will pass through the bottom plate 13 through the diversion hole 132, and then flow along the corresponding guide surface 131 toward the adjacent sewage outlet 122, thereby having the effect of flushing the guide surface 131, and further facilitating the discharge of impurities that fall to the top of the bottom plate 13.

[0077] Furthermore, preferably, a plurality of impellers 133 are rotatably mounted on the bottom plate 13 .

[0078] The impeller 133 is a cylindrical structure as a whole and is located in the guide hole 132 . The rotation axis of the impeller 133 coincides with its own axis and is parallel to the width direction of the base plate 13 .

[0079] 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-resistant 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.

[0080] Reference Figure 1 and Figure 3 The frame 14 is a rectangular parallelepiped frame structure, fixedly mounted on the top of the floating board and located above the illumination port 111. In this embodiment, the length of the frame 14 is preferably parallel to the length of the floating board 11, and the width of the frame 14 is preferably parallel to the width of the floating board 11. Furthermore, the length and width of the frame 14 are preferably compatible with the length and width of the illumination port 111, respectively.

[0081] The shading plate 15 is a rectangular plate-shaped structure, which is movably mounted on the top of the frame 14, and its movable direction is parallel to the length direction of the frame 14. In this embodiment, the length direction of the shading plate 15 is preferably parallel to the length direction of the frame 14, and the width direction of the shading plate 15 is preferably parallel to the width direction of the frame 14.

[0082] Reference Figure 1 and Figure 2 , the sunshade 15 is restricted in its movement relative to the frame 14; when the two sunshades 15 are moved to the extreme position in the direction close to the frame 14, the two sunshades 15 can jointly form a shield above the light opening 111; when the two sunshades 15 are moved to the extreme position in the direction away from the frame 14, the two sunshades 15 will be located on both sides of the length direction of the frame 14 respectively. At this time, natural light can smoothly pass through the light opening 111 into the ecological space 121.

[0083] Reference Figure 3 and Figure 4 Furthermore, it is preferred that the bottom plate 13 can drive the two light shielding plates 15 to move relative to the frame 14 during its movement relative to the ecological cage 12. When the bottom plate 13 moves toward the ecological cage 12 to its limit position, the two light shielding plates 15 will also move toward the frame 14 to their limit positions; when the bottom plate 13 moves toward the ecological cage 12 to its limit position, the two light shielding plates 15 will also move toward the frame 14 to their limit positions. In this embodiment, the sunshade 15 preferably also has a rack structure along its own length direction, and the base plate 13 preferably has two extension rods extending upward, and the two extension rods correspond one-to-one to the two sunshades 15; a gear is rotatably installed on the frame 14 for the corresponding extension rods to engage with the sunshade 15, and the engagement of the gear and the rack forms a linkage between the base plate 13 and the sunshade 15, and the movements of the two sunshades 15 are synchronized and reversed; since the above-mentioned linkage method between the base plate 13 and the sunshade 15 is a common existing technology, it will not be described in detail here, and it is only briefly represented in the accompanying drawings.

[0084] Reference Figure 1 and Figure 3 The attachment assembly 2 includes a plurality of attachment tubes 21 for the pollution-resistant algae to attach and grow, and a first driving member 22 for driving the attachment tubes 21 to move and change the position of the pollution-resistant algae.

[0085] The attachment tube 21 is cylindrical in structure, with an outer surface structure for the attachment and growth of tolerant algae. 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 of the ecological cage 12. Multiple attachment tubes 21 are evenly spaced along the length of the ecological cage 12, and the ecological cage 12 is equipped with a structure for rotating the multiple attachment tubes 21 in the same direction and synchronously. In this embodiment, the multiple attachment tubes 21 preferably rotate in the same direction and synchronously using a synchronous belt structure. Since the synchronous belt structure is common in the prior art, it will not be described in detail here and is omitted in the accompanying drawings.

[0086] The first drive member 22 is fixedly mounted on the top of the floating board 11 and is used to drive the multiple attachment cylinders 21 to rotate synchronously and in the same direction relative to the ecological cage 12. In this embodiment, the first drive member 22 is preferably a servo motor, which directly drives the rotation of the adjacent attachment cylinders 21. Preferably, the first drive member 22 drives the rotation of the attachment cylinders 21 via a synchronous belt structure. Since the servo motor and synchronous belt structure are both common existing technologies, they will not be described in detail here, and they are only briefly illustrated in the accompanying drawings.

[0087] Reference Figure 3 and Figure 4 The fill light assembly 3 includes a plurality of first fill light pieces 31 and a plurality of second fill light pieces 32 corresponding to the plurality of attachment tubes 21 one by one.

[0088] The first fill light element 31 is fixedly mounted within the corresponding attachment tube 21 and is capable of emitting light outward with the axis of the attachment tube 21 as its axis. The inner structure of the attachment tube 21 is designed to be light-transmissive, allowing the pollution-tolerant algae growing on the attachment tube 21 to absorb the supplemental light from the first fill light element 31. In this embodiment, since the first fill light element 31 and the attachment tube 21, which perform the above-described functions, are both common prior art, they will not be described in detail here, and only a brief description will be provided in the accompanying drawings.

[0089] The second fill light component 32 is an overall arc-shaped plate structure, which is fixedly installed on the ecological cage 12 and located in the ecological space 121. It is located below the corresponding attachment tube 21 and is aligned with the corresponding attachment tube 21 in the vertical direction; the arc structure of the second fill light component 32 protrudes toward the direction close to the corresponding attachment tube 21, and the arc trajectory of the second fill light component 32 is perpendicular to the axis of the corresponding attachment tube 21.

[0090] The second fill light component 32 can provide supplementary lighting radially toward the corresponding attachment tube 21 with the axis of its own arc trajectory as the axis, so that the pollution-resistant algae attached to the bottom of the attachment tube 21 can fully absorb the light; at the same time, impurities such as metabolic products during the growth of the pollution-resistant algae on the attachment tube 21 fall onto the corresponding second fill light component 32, and can slide along the arc surface of the second fill light component 32 and finally be discharged through the sewage outlet 122.

[0091] Furthermore, in order to further reduce the impact of impurities falling on the surface of the second fill light 32 and ensure the supplementary lighting effect of the second fill light 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 tube 21.

[0092] During the rotation of the attachment tube 21 relative to the ecological cage 12, the bristles 211 close to the corresponding second fill light component 32 can contact and resist the curved surface of the second fill light component 32, thereby cleaning the curved surface of the second fill light component 32 and further reducing the probability of impurities staying on the surface of the second fill light component 32.

[0093] Furthermore, in order to further improve the utilization rate of natural light and supplementary light from the supplementary light component 3 by the pollution-tolerant algae, it is preferred that a plurality of reflectors 5 are installed on the inner walls on both sides of the ecological space 121 in the longitudinal direction of the ecological cage 12.

[0094] The reflective surface of the reflector 5 is tilted upward toward the center of the ecological space 121, and is capable of reflecting the natural light and supplementary light it receives, and reflecting the light onto the adjacent attachment tube 21. In this embodiment, since the reflector 5 having the above-mentioned functions is common in the prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0095] Reference Figure 1 and Figure 3 The energy supply component 4 includes multiple solar panels 41 and energy supply components 42.

[0096] Solar panels 41 are fixedly mounted on top of the floating board 11, with multiple solar panels 41 closely arranged on top of the floating board 11. In this embodiment, the solar panels 41 are preferably capable of absorbing natural sunlight to generate energy. Since solar panels 41 with such functions are common in the prior art, they will not be described in detail here, and will only be briefly illustrated in the accompanying drawings.

[0097] The energy supply component 42 is fixedly installed on the top of the floating board 11, and is electrically connected to multiple solar panels 41 at the same time, and multiple solar panels can supply energy to it at the same time; the energy supply component 42 is also electrically connected to the first driving component 22, the second driving component 16, multiple first fill light components 31 and multiple second fill light components 32 at the same time to supply energy to them.

[0098] Reference Figure 2 and Figure 4The energy supply component 42 is also simultaneously connected to multiple solar panels 41, multiple first fill-light components 31, and multiple second fill-light components 32. When the amount of energy supplied to the energy supply component 42 by the solar panels 41 due to light absorption decreases to a certain value (i.e., on a cloudy day or at night), the energy supply component 42 will control the multiple first fill-light components 31 and multiple second fill-light components 32 to supplement the light supply to the pollution-resistant algae, allowing the fill-light component 3 to promptly supplement the light supply to the pollution-resistant algae when natural light conditions are insufficient. Furthermore, during the process of supplementing the light supply to the pollution-resistant algae, the fill-light component 3 can, to a certain extent, increase the temperature of the environment surrounding the pollution-resistant algae, making the temperature conditions more suitable for the growth and activity of the pollution-resistant algae. In this embodiment, since the energy supply component 42 with the above-mentioned functions is a common prior art, it will not be described in detail here, and will only be briefly illustrated in the accompanying drawings.

[0099] Reference Figure 1 and Figure 3 Furthermore, the second driver 16 is preferably signal-connected to the fill light assembly 3. When the fill light assembly 3 is in standby mode, the second driver 16 drives the bottom plate 13 to move away from the ecological cage 12 to its limit position and maintains it there. Simultaneously, the two sunshades 15 move away from the frame 14 to their limit positions and maintain them there, allowing the pollution-resistant algae to absorb natural light.

[0100] Reference Figure 2 and Figure 4 When the supplementary light assembly 3 is in operation, the second driving member 16 will drive the bottom plate 13 to move toward the ecological cage 12 to the extreme position and maintain it. At the same time, the two shading plates 15 will also move toward the frame 14 to the extreme position and maintain it. At this time, the bottom plate 13 and the two shading plates 15 can both prevent the supplementary light from diffusing outward, thereby effectively reducing the probability of the supplementary light misleading ships and attracting birds and fish to approach and prey on pollution-resistant algae.

[0101] Reference Figure 1 and Figure 3 Furthermore, when both shading members are moved to their extreme positions away from the frame 14, they can form two light-shielding areas above the floating board 11. Furthermore, preferably, multiple solar panels 41 are mounted on the floating board 11 outside the light-shielding areas, while the energy supply member 42, the first drive member 22, and the second drive member 16 are all mounted on the floating board 11 within the light-shielding areas. This allows the solar panels 41 to stably absorb natural sunlight to provide energy, while effectively reducing the impact of natural sunlight on the energy supply member 42, the first drive member 22, and the second drive member 16, thereby extending the service life of the energy supply member 42, the first drive member 22, and the second drive member 16.

[0102] The implementation principle of an ecological restoration device in the embodiment of the present application is as follows:

[0103] During the process of the pollution-resistant algae attaching and growing on the attachment tubes 21, the first driving member 22 drives the multiple attachment tubes 21 to keep rotating, so that the pollution-resistant algae receive more uniform light, thereby increasing the activity of the pollution-resistant algae and facilitating their growth.

[0104] Generally, the pollution-tolerant algae will receive natural light during the day. When there is insufficient natural light (such as on a cloudy day or at night), the supplementary light component 3 will operate to provide additional light for the pollution-tolerant algae, so that the pollution-tolerant algae can still fully absorb light, maintain growth and maintain a high level of activity.

[0105] By cultivating and growing a certain amount of pollution-resistant algae and keeping them highly active, ecological restoration of polluted marine areas can be carried out.

[0106] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
