Description

A multifunctional ecological barrier for the restoration of submerged vegetation in lakes Technical Field

[0001] This application relates to the field of vegetation ecological restoration technology, and in particular to a multifunctional ecological enclosure for the restoration of submerged vegetation in lakes. Background Technology

[0002] Currently, with the increasing eutrophication of many urban lakes, phytoplankton are proliferating, water transparency is severely reduced, leading to insufficient underwater light intensity, limiting the normal germination and growth of submerged plants, and even causing large-scale decline of submerged vegetation. Therefore, ecological enclosure to assist the restoration of submerged vegetation has become an important means of lake aquatic ecological restoration.

[0003] However, in existing technologies, ecological enclosures are mostly based on physical isolation, and their main functions are to prevent fish, control algae, and block pollution. They lack the ability to regulate the ecosystem and are difficult to adapt to the multi-factor requirements of submerged vegetation restoration, such as light and hydrodynamics, resulting in poor continuous restoration of submerged vegetation. Summary of the Invention

[0004] This application provides a multifunctional ecological enclosure for the restoration of submerged vegetation in lakes, which can improve the growth effect of submerged vegetation and at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this application provides a multifunctional ecological enclosure for the restoration of submerged vegetation in lakes, comprising: multiple insertable rods configured to be vertically inserted into the water surrounding the enclosure object, wherein adjacent insertable rods are respectively a first hollow rod and a second hollow rod; a fence connected to the side of the multiple insertable rods away from the enclosure object, and the fence is configured to circumferentially surround the enclosure object; and a supplementary lighting mechanism connected between the first hollow rods and the second hollow rods and close to the bottom surface of the water body, wherein the supplementary lighting... The mechanism has a light-emitting surface configured to emit light horizontally towards the submerged vegetation in the water area surrounding the enclosure object; a flushing and turbulence-disrupting mechanism is disposed between the first hollow rod and the supplementary lighting mechanism. The flushing and turbulence-disrupting mechanism is configured to draw water from the upper layer of the water body surrounding the enclosure object and spray it from below the light-emitting surface from bottom to top to flush the light-emitting surface. The water flow sprayed by the flushing and turbulence-disrupting mechanism creates a slight turbulence between the light-emitting surface and the submerged vegetation after flushing the light-emitting surface.

[0006] Optionally, the supplemental lighting mechanism includes a full-spectrum lamp tube and a lamp tube cover. The lamp tube cover is horizontally connected to the rod wall of two adjacent plug rods near the bottom of the water. The full-spectrum lamp tube is fixed inside the lamp tube cover and separated from the water. The first outer wall of the lamp tube cover facing the submerged vegetation is the light-emitting surface, and the second outer wall of the lamp tube cover away from the light-emitting surface is the light-shielding surface.

The water pump is installed inside the cavity of the first hollow rod. The first end of the suction pipe is connected to the pump inlet of the water pump, and the second end of the suction pipe extends through the wall of the first hollow rod into the upper water layer. The first end of the drain pipe is connected to the pump outlet of the water pump. A floor panel is also provided below the lamp cover. The floor panel is connected to the lower edge of the inclined panel and is attached to the bottom surface. The second end of the drain pipe extends through the wall of the first hollow rod into the lower water layer. The spray pipe is connected to the second end of the drain pipe and is attached to the upper surface of the floor panel along its length. Multiple nozzles are spaced apart on the spray pipe, and each nozzle is vertically upward and angled relative to the light-emitting surface.

[0010] Optionally, the flushing and turbulence mechanism further includes a turbulence component, which includes a guide plate, a curved plate, and an extension plate. The guide plate is arranged parallel above the inclined plate, and the surface of the guide plate is on the same plane as the light-emitting surface. The first edge of the curved plate is connected to the top of the guide plate, and the second edge of the curved plate extends downward at an angle away from the guide plate. The cross-sectional shape of the inner surface of the curved plate is arc-shaped. The extension plate is connected parallel to the second edge of the curved plate. The water flow sprayed from the nozzle is configured to pass sequentially through the light-emitting surface, the surface of the guide plate, the inner surface of the curved plate, and the surface of the extension plate before moving downward at an angle to the submerged vegetation side in the water area surrounding the enclosure object.

[0011] Optionally, it also includes a power supply mechanism, which is disposed on the plug rod and electrically connected to the supplementary lighting mechanism.

[0012] Optionally, the power supply mechanism includes a solar panel and a battery. The solar panel is disposed on the top of the plug rod, and the battery is installed in the inner cavity of the plug rod. The battery is electrically connected to the solar panel and the supplementary lighting mechanism.

[0013] Optionally, the top of the plug rod is provided with a horizontal mounting plate, and two solar panels are obliquely mounted on the mounting plate. The cross-sectional shape formed by the mounting plate and the two solar panels is an isosceles acute triangle. A ventilation opening is provided through the mounting plate, and the ventilation opening is located directly below the vertical projection formed by the two solar panels.

[0014] Optionally, a perching board is provided on top of the joint between the two solar panels.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By vertically inserting a first hollow rod and a second hollow rod into the water surrounding the enclosure object, and using the connecting rods to form a net, it can, to a certain extent, prevent floating debris from entering the water area surrounding the enclosure object. Simultaneously, a supplementary lighting mechanism projects light horizontally onto the submerged vegetation, ensuring that the light reaches submerged plants below the usual light compensation depth, providing them with a beneficial light environment for growth. 2. A scouring and turbulence mechanism pumps water from the upper water layer and sprays it upwards to scour the light-exposed surface, creating turbulence between the light-exposed surface and the submerged plants. This helps to inhibit the deposition of algae or other attachments on the light-exposed surface, while also improving the boundary layer thickness on the leaf surface of the submerged plants, allowing for more effective exchange of inorganic carbon and nutrients, thereby improving the photosynthetic efficiency and growth status of the submerged vegetation to a certain extent. Through this combination of structure and function, the present invention establishes a relatively stable, light-rich microenvironment with moderate water disturbance around the lake enclosure, which is conducive to the recovery and growth of submerged plants. 2. The flushing and turbulence mechanism is further equipped with turbulence components, including a guide plate, a curved plate, and an extension plate. By guiding the water flow sprayed from the nozzle, the water flow passes sequentially through the light-exposing surface, the guide plate surface, the inner surface of the curved plate, and the extension plate surface before flowing downwards at an angle towards the submerged vegetation side of the water area surrounding the enclosure, thereby forming a more continuous and gentle water turbulence between the light-exposing surface and the submerged plants. This turbulence can simulate the natural water flow environment to a certain extent, prompting the stems and leaves of submerged plants to receive continuous physical stimulation, which may cause their stems to grow thicker, thereby enhancing the plants' adaptability to water flow and wave impact, and reducing the risk of lodging and breakage.This structured water flow guidance mechanism simultaneously increases water mixing between the surface and lower layers of the water body, which is beneficial to improving the utilization efficiency of light and nutrients, enabling submerged vegetation to obtain higher resource availability in its growth environment; 3. The flushing and turbulence mechanism extracts water from the upper water area and sprays it upwards onto the light-emitting surface, so that the jet water flow first continuously flushes the light-emitting surface, reducing the adhesion of algae and impurities to a certain extent, thereby maintaining the light transmission state of the light-emitting area; at the same time, after passing the light-emitting surface, the jet water flow, combined with the guiding effect of the guide plate, bending plate and extension plate in the turbulence component, is redistributed along a preset path and flows downwards at an angle towards the submerged vegetation area, forming a continuous and relatively mild turbulent water environment between the light-emitting surface and the submerged plants. This disturbance is beneficial to weakening the boundary layer thickness on the surface of plant leaves. This promotes the exchange of inorganic carbon and nutrients, and provides moderate hydrodynamic stimulation to plant stems and leaves, making the plant structure more robust. Thus, within the same structural system, it simultaneously achieves two functions: cleaning the light-emitting surface and regulating water disturbance, resulting in a synergistic effect on the comprehensive improvement of the growth environment for submerged vegetation. 4. The solar panels of the power supply system are arranged at an angle, with perches extending along the joints of the solar panels and positioned above them. This allows birds to briefly perch or stand in this location, giving the ecological enclosure a bio-friendly attribute from a structural perspective, which is beneficial for attracting bird activity and enhancing the diversity of the aquatic ecosystem. Simultaneously, the perches are made of glass, whose light-transmitting properties allow natural light to penetrate along the incident direction of the perch and reach the surface of the solar panels below, which is beneficial for the absorption and conversion of light energy by the solar panels, thereby maintaining the stable operation of the power supply system. In rainy conditions, the perches are positioned above the solar panels and form a certain shading angle, allowing rainwater to preferentially slide off along the outer edge of the perch, reducing the probability of rainwater directly adhering to the surface of the solar panels, which helps to reduce the adverse effects of water stains on power generation efficiency. In addition, the glass surface is relatively smooth and has weak surface adhesion. When birds produce droppings while roosting, combined with rainwater or natural flushing conditions, the droppings are more likely to detach from the surface of the perch, thereby reducing the possibility of long-term adhesion of pollutants. Overall, this is beneficial to the long-term use and maintenance of ecological enclosure structures in outdoor environments. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] This application provides a multifunctional ecological enclosure for the restoration of submerged vegetation in lakes. Please refer to Figures 1, 2 and 3. The enclosure includes a plug-in rod 1, a fence 2, a supplementary lighting mechanism 3 and a flushing and disturbance mechanism 4.

[0022] For example, multiple insertion rods 1 are configured to be vertically inserted into the water body surrounding the enclosure object, with adjacent insertion rods 1 being a first hollow rod 11 and a second hollow rod 12, respectively. Furthermore, the lower end of the insertion rod 1 has a perching plate 7, through which the insertion rod 1 can be securely inserted into the mud in the water body.

[0023] For example, the netting 2 is connected to the side of the multiple connecting rods 1 away from the object being enclosed, and the netting 2 is configured to circumferentially surround the object being enclosed; for example, the netting 2 is an impermeable netting or a semi-permeable netting. Further, the netting 2 is arranged in a sheet-like or mesh-like structure circumferentially around the object being enclosed. The netting 2 has a certain aperture and strength in its structure, capable of preventing large floating plant debris, plastic fragments, fallen leaves, and other external debris from entering the submerged plant growth area, thereby maintaining the habitat stability around the submerged plants to a certain extent. Specifically, the connection between the netting 2 and the connecting rods 1 can be completed through slots, straps, or threaded connections, thereby maintaining high assembly reliability under conditions of wind, waves, and water flow changes.

[0024] For example, the supplemental lighting mechanism 3 is connected between the first hollow rod 11 and the second hollow rod 12 and is close to the bottom of the water body. The supplemental lighting mechanism 3 has a light-emitting surface 3221, which is configured to emit light horizontally towards the submerged vegetation in the surrounding water area of ​​the enclosure object. Furthermore, the light-emitting surface 3221 can project the light generated by the artificial light source into the area where the submerged vegetation is located in a horizontal beam manner, thereby providing additional light energy support for the submerged plants under conditions of reduced water transparency and insufficient natural light. Specifically, the light-emitting surface 3221 can be a flat glass cover, a pressed transparent resin panel, or a sealed structure with a light-transmitting window, and needs to be designed for pressure resistance, seepage prevention, and anti-adhesion performance in conjunction with underwater use. Since the optimal light-receiving area for submerged plants is usually located at different depths, the installation depth of the supplemental lighting mechanism 3 can be adjusted by changing the installation height of the first hollow rod 11 and the second hollow rod 12 to adapt to the plant growth needs under different lake, water level, or seasonal conditions.

[0025] For example, the flushing and turbulence mechanism 4 is disposed between the first hollow rod 11 and the supplementary lighting mechanism 3. The flushing and turbulence mechanism 4 is configured to draw water from the upper water area of ​​the outer perimeter of the enclosure object and spray it from below the light-emitting surface 3221 from bottom to top to flush the light-emitting surface 3221. After flushing the light-emitting surface 3221, the water flow sprayed by the flushing and turbulence mechanism 4 forms turbulence between the light-emitting surface 3221 and the submerged vegetation.

[0026] Furthermore, the plug-in rod 1 has a hollow internal structure, providing installation space for laying cables, water pipes, or fixing components for the lighting mechanism 3 and the flushing and turbulence-disrupting mechanism 4. The difference between the first hollow rod 11 and the second hollow rod 12 lies only in the allocation of the installation positions for the lighting mechanism 3 and the flushing and turbulence-disrupting mechanism 4. Both can be circular or polygonal hollow rods, and the materials can be corrosion-resistant metals or high-strength engineering plastics to adapt to long-term underwater working environments.

[0027] It is understandable that the flushing and turbulence-disrupting mechanism 4 draws water from the upper layer of the water surrounding the enclosure object and then sprays it upwards from below the light-emitting surface 3221 through nozzles. The temperature of the upper water layer is usually higher than that of the lower water layer. This temperature difference creates a small density gradient difference between the light-emitting surface 3221 and the submerged vegetation after spraying, causing stable disturbance as the sprayed water flows through the lower water layer, thus creating a continuous turbulent environment around the light-emitting surface 3221 and the vegetation leaves. The sprayed water first flushes the surface of the light-emitting surface 3221 in the water, which can reduce the probability of algae attaching or multiplying on the surface of the light-emitting surface 3221. This is because most algae prefer weak flow environments and often stay in the upper light-suit area by adjusting buoyancy. When the surface of the light-emitting surface 3221 receives continuous light flushing, it is not conducive to algae attachment and reproduction, thus reducing the risk of the light-emitting surface 3221 being blocked by algae to a certain extent. As the water continues to spread outwards, it passes over the leaves of submerged plants, which to some extent weakens the boundary layer thickness on the plant surface. This makes it easier for inorganic carbon sources such as carbon dioxide and bicarbonate to reach the leaf surface, while also increasing the diffusion rate of oxygen and metabolic byproducts. This, in turn, improves the efficiency of photosynthesis and nutrient absorption in submerged plants. The continuous, low-speed turbulence also creates a gentle hydrodynamic stimulus on the plant stems and leaves. In this environment, plants are more likely to develop thicker, more resilient stem structures, which helps improve their stability under the impact of natural wind, waves, and water currents.

[0028] Based on this, the entire ecological enclosure structure forms an independent and open submerged vegetation restoration zone around the enclosure object. The enclosure net 2 forms the basic habitat boundary, the supplementary lighting mechanism 3 provides light energy compensation, and the scouring and disturbance mechanism 4 forms hydrodynamic regulation. The three, together with the plug rod 1, constitute a complete system. Each structure corresponds to a specific function and encourages the recovery and growth of submerged plants and improves the stability of planting through underwater synergy, and provides structural support for lake ecological restoration.

[0029] In some embodiments, as shown in Figures 1, 2, and 3, the supplemental lighting mechanism 3 includes a full-spectrum lamp tube 31 and a lamp tube cover 32. The lamp tube cover 32 is horizontally connected to the wall of two adjacent plug-in rods 1 near the bottom of the water, so that the supplemental lighting mechanism 3 forms a stable and continuous transverse light band in the bottom area of ​​the water body. The full-spectrum lamp tube 31 is fixed inside the lamp tube cover 32 and separated from the water. Specifically, when working, the full-spectrum lamp tube 31 can provide a wide-spectrum radiation close to natural light, which is more suitable for submerged plants to absorb. It contains blue light and red light components required for photosynthesis. This spectral characteristic, combined with the high light transmittance structure of the light-emitting surface 3221, is beneficial to improving the light environment of submerged plants under the condition of decreased water transparency.

[0030] For example, the first outer wall of the lamp cover 32 facing the submerged vegetation is the light-emitting surface 3221. Specifically, the light-emitting surface 3221 is structurally configured to have high light transmittance, and its material can be tempered glass, transparent acrylic, polycarbonate sheet, or resin-based light-transmitting material with waterproof and pressure-resistant properties, so that the light emitted by the full-spectrum lamp tube 31 can enter the water body with high transmittance and illuminate the leaf area of ​​the submerged vegetation.

[0031] For example, the second outer wall of the lamp cover 32 facing away from the light-emitting surface 3221 is a light-shielding surface 3211. The light-shielding surface 3211 can be made by using an opaque material or by coating a reflective coating on its surface. Specifically, the light-shielding surface 3211 may include a stainless steel back plate, an aluminum alloy plate, an engineering plastic plate, or a composite material with a metal reflective film covering the outside of a transparent plate. The light-shielding surface 3211 is structurally beneficial in reducing the diffusion of light to the back area, allowing the light to be projected more concentratedly in the direction of the submerged vegetation distribution, thereby improving the light energy utilization efficiency.

[0032] It is understandable that the lamp cover 32 separates the full-spectrum lamp 31 from the water. Its sealed structure keeps the full-spectrum lamp 31 in a dry cavity, which can reduce the impact of water pressure and lake water corrosion on the lamp assembly to a certain extent, and is beneficial to extending the service life of the supplementary lighting mechanism 3. The plug rod 1 provides fixed support for the lamp cover 32. The lamp cover 32 is horizontally connected between the two plug rods 1 to form a stable light direction. At the same time, the light-emitting surface 3221 is clearly designed to point towards the submerged vegetation area so that the light distribution is consistent with the plant growth area and avoids irradiation deviation. The light-emitting surface 3221 and the light-shielding surface 3211 of the lamp cover 32 form a light radiation direction structure. This structural mode has practical significance in the underwater environment because the water will scatter the light. When the functional division of the light-emitting surface 3221 and the light-shielding surface 3211 is clear, the light is more likely to be concentrated and propagated to the target area, thereby improving the supplementary lighting effect to a certain extent and enabling submerged plants to obtain more suitable lighting conditions in a low-light environment. The structural design and material selection of the entire supplementary lighting mechanism 3 work together to provide suitable supplementary lighting conditions for submerged vegetation and, together with the ecological enclosure, improve the underwater ecological environment around the enclosure object.

[0033] In some embodiments, referring to FIG2, the lamp cover 32 includes an arc plate 321 and an inclined plate 322. The cross-sectional shape of the arc plate 321 is arc-shaped, and the cross-sectional shape of the inclined plate 322 is inclined. The inclined plate 322 is connected to the notch of the arc plate 321, so that the lamp cover 32 forms a combined configuration with an arc-shaped sidewall and an inclined transparent sidewall.

[0034] For example, the outer wall surface of the arc plate 321 is a light-shielding surface 3211, which faces the outer area of ​​the enclosure object and shields it; further, the outer wall surface of the inclined plate 322 is a light-emitting surface 3221, and the light-emitting surface 3221 is inclined towards the bottom side.

[0035] For example, the arc plate 321 is usually made of opaque or low light-transmitting material, which is beneficial to direct the light radiation mainly in the direction of the inclined plate 322, while the inclined plate 322 can be made of high light-transmitting material, such as transparent acrylic plate, polycarbonate plate or tempered glass, so that the light emitted by the lamp tube enters the water body with a higher light transmittance.

[0036] It is understandable that the downward tilting structure of the inclined panel 322 has practical significance in the underwater environment. In a still water environment, phytoplankton, fine particles of silt or other pollutants are usually more likely to adhere to the horizontal or near-horizontal transparent panel. When the light-emitting surface 3221 is arranged at an angle tilted towards the bottom, it can reduce the probability of sedimented particles or phytoplankton remaining on the transparent surface to a certain extent, thereby helping to maintain the cleanliness of the surface of the light-emitting surface 3221.

[0037] Furthermore, when the water jet from the scouring and turbulence mechanism 4 impacts the light-emitting surface 3221 from bottom to top, the tilt angle of the light-emitting surface 3221 allows the water jet to form an adhering flow along the light-emitting surface 3221. During the contact process with the transparent plate surface, the water jet exerts a shearing effect on the adhering material, making it easier for the pollutants to be peeled off by the water jet and slide down. Because the light-emitting surface 3221 is tilted, the pollutants after peeling are not easy to stay or accumulate on its surface again, which is beneficial to maintaining the light-emitting surface 3221 in a high light-transmitting state for a long time.

[0038] Meanwhile, the structural relationship between the arc-shaped plate 321 and the inclined plate 322 also gives the lamp cover 32 a good hydrodynamic shape. The arc structure has less resistance when facing the water, which can improve the stability of the lamp cover 32 when the water flow is strong. The tilt angle of the inclined plate 322 can also be appropriately changed according to the actual water depth, water flow direction and supplementary lighting needs of the lake. By adjusting the tilt angle, different light coverage areas and light intensity distributions can be obtained, making the supplementary lighting effect more in line with the location requirements of the submerged plant growth area.

[0039] Overall, the structure of the lamp cover 32, which is composed of the arc plate 321 and the inclined plate 322, is synergistic in terms of light distribution, underwater cleanliness and water flow scouring assistance, enabling the supplementary lighting mechanism 3 to play a more stable role in supporting light during the restoration of submerged plants in the lake.

[0040] In some embodiments, as shown in Figure 2, the inner wall surface of the arc plate 321 is a reflective surface 3212; further, the reflective surface 3212 is formed by providing a high reflectivity coating or attaching a reflective film to the inner surface of the arc plate 321. The reflective film can be made of aluminum metal mirror layer, stainless steel polished layer, silver-white reflective coating, vacuum-plated aluminum film, anodized reflective layer or other composite materials with high underwater corrosion resistance and stable reflectivity.

[0041] For example, the full-spectrum lamp tube 31 is spaced apart from the arc plate 321 and the inclined plate 322. The reflective surface 3212 is located in the circumferential area of ​​the full-spectrum lamp tube 31 and is spaced apart from the full-spectrum lamp tube 31. This allows the light emitted by the lamp tube to propagate towards the reflective surface 3212 and be reflected on the surface of the reflective surface 3212. This further concentrates the reflected light along the inclined plate 322, thereby reducing the scattering loss of light inside the lamp tube cover 32 to a certain extent and enhancing the luminous flux radiated towards the light-emitting surface 3221.

[0042] It is understandable that the spacing between the full-spectrum lamp tube 31 and the arc plate 321 creates a certain spatial distance between the light beams along their propagation path. This helps to create uniform reflection and diffusion of the light within the arc-shaped cavity, allowing light from different directions to concentrate more towards the inclined panel 322 area after reflection. Consequently, the light-emitting surface 3221 receives relatively uniform and high-intensity light input. Similarly, the spacing between the full-spectrum lamp tube 31 and the inclined panel 322 prevents the lamp tubes from directly adhering to the inclined panel 322. This reduces the thermal impact of the lamp tubes on the transparent panel and facilitates the formation of a stable flow field on the outside of the inclined panel 322 from the water jet sprayed by the flushing and turbulence mechanism 4. The space between the lamp tubes and the water jets does not obstruct the water flow. The combined structure of the reflective surface 3212 and the inclined light-emitting surface 3221 creates a secondary light convergence path inside the lamp cover 32. The arc-shaped reflective surface 3212 can reflect the light that originally propagated towards the opposite area back towards the light-emitting surface 3221, so that the light energy is distributed in the circumferential range and concentrated towards the submerged plant in a beneficial way, thereby providing a relatively higher supplementary lighting efficiency in the environment where the submerged plant is under-lit.

[0043] In some embodiments, referring to Figures 1, 2 and 3, the flushing and turbulence mechanism 4 includes a flushing assembly 41, which includes a water pump 411, a water suction pipe 412, a water discharge pipe 413, a water spray pipe 414 and a nozzle 415.

[0044] For example, the water pump 411 is installed inside the cavity of the first hollow rod 11, the first end of the water pump 412 is connected to the pump inlet of the water pump 411, and the second end of the water pump 412 extends into the upper water layer after passing through the rod wall of the first hollow rod 11. This allows the temperature of the pumped water to be relatively high and has less impact on the near-bottom habitat of submerged plants.

[0045] For example, the first end of the drain pipe 413 is connected to the pump outlet of the water pump 411, and a floor 8 is provided below the lamp cover 32. The floor 8 is connected to the lower edge of the inclined panel 322 and is in contact with the bottom surface of the water. The second end of the drain pipe 413 passes through the rod wall of the first hollow rod 11 and extends into the lower water area of ​​the water body, so that the pumped upper water body can be transported to the vicinity of the lower water area and used as a flushing water source.

[0046] For example, the water spray pipe 414 is connected to the second end of the drain pipe 413, and the water spray pipe 414 is attached to the upper surface of the floor 8 along the length of the floor 8. This structure makes the floor 8 the mounting reference surface for the water spray pipe 414, which helps to stabilize the water spray direction and reduce the deviation of the water flow before it is sprayed. Furthermore, multiple nozzles 415 are spaced apart on the water spray pipe 414, and each nozzle 415 is vertically upward and at an angle to the light-emitting surface 3221. In this way, the spray direction forms an angle relationship with the inclined panel 322, so that the sprayed water flow can be directed towards the inclined light-emitting surface 3221 from bottom to top. Since the light-emitting surface 3221 forms a certain angle towards the bottom, after the water flow sprayed by the nozzle 415 contacts the lower part of the light-emitting surface 3221, it continues to slide upward along the light-emitting surface 3221 under the action of inertia, so that the entire outer surface of the light-emitting surface 3221 is covered by water flow. This structure allows the flushing water flow to effectively remove dirt, microbial aggregates, and algae from the surface of the polishing surface 3221. The inclined polishing surface 3221 also causes the particles that are washed off to slide outwards under the combined action of gravity and water flow, making them less likely to re-adhere to the vicinity of the polishing surface 3221. At the same time, the nozzles 415 are distributed at multiple points along the length direction, so that the polishing surface 3221 can obtain a relatively uniform flushing flow in the width direction, reducing the possibility of insufficient cleaning in certain areas.

[0047] It is understandable that the water temperature drawn from the upper layer is usually higher than that of the lower layer. When sprayed near the light-emitting surface 3221, it creates disturbance in the area between the light-emitting surface 3221 and the submerged plants, keeping the water flow in this area dynamic and reducing the probability of algae accumulation in this illuminated area. Since most algae tend to accumulate and remain in the well-lit water layer in a still water environment, the upward water flow can disrupt the conditions for algae accumulation to a certain extent, making it less likely for algae to continuously adhere to the light-emitting surface 3221. The structure of the water spray pipe 414 attached to the floor 8 also results in a lower starting height of the spray flow, allowing for a more comprehensive coverage of the flushing path and enhancing the cleaning effect of the area near the bottom of the light-emitting surface 3221. The combination of these structures makes the supplemental lighting environment more stable, maintains the transparency of the light-emitting area of ​​the lamp at a level conducive to the growth of submerged plants, and makes the water exchange in the disturbance zone more active, which is beneficial to improving the photosynthetic efficiency and nutrient exchange capacity of submerged plants, while reducing the competitive pressure on algae, thereby promoting the improvement of the growth environment for submerged plants.

[0048] In some embodiments, referring to Figures 1, 2 and 3, the scouring and turbulence mechanism 4 further includes a turbulence component 42, which includes a guide plate 421, a bending plate 422 and an extension plate 423.

[0049] For example, the guide plate 421 is disposed parallel above the inclined plate 322, and the plate surface of the guide plate 421 is on the same plane as the light-emitting surface 3221. This structure enables the water flow rising from the light-emitting surface 3221 to maintain a basically consistent flow direction before entering the area of ​​the guide plate 421, which helps to reduce the probability of the water flow being deflected at this position.

[0050] For example, the first edge of the curved plate 422 is connected to the top of the guide plate 421, and the second edge of the curved plate 422 extends downward at an angle away from the guide plate 421. The cross-sectional shape of the inner surface of the curved plate 422 is arc-shaped. For the water flow, the arc-shaped surface guides it to gradually change direction, so that the water flow does not suddenly turn when it comes into contact with the arc-shaped surface, but continues to deflect along the arc surface of the curved plate 422. Further, the extension plate 423 is connected in parallel to the second edge of the curved plate 422. The water flow sprayed from the nozzle 415 is configured to pass sequentially through the light-emitting surface 3221, the surface of the guide plate 421, the inner surface of the curved plate 422, and the surface of the extension plate 423 before moving downward at an angle to the submerged vegetation side in the water area surrounding the enclosure object.

[0051] It is understandable that the water jet from nozzle 415, part of which is in the preceding structure, moves upward along the light-emitting surface 3221 due to inertia. When it encounters the obstruction of the water flow already present in the water body, its velocity will decrease to a certain extent. The other part of the water flow, which has not completely decreased, enters the area of ​​guide plate 421 due to its relatively greater kinetic energy. It is then gradually changed in direction by the arc surface of bending plate 422, and finally flows to the side of the submerged plant through extension plate 423 along a downward oblique path, thus creating a continuous disturbance in the water body around the submerged plant. This disturbance is relatively mild in both intensity and direction. The water flow produces a periodic, mild stress stimulus on the plant stems and leaves. Under long-term effects, this is beneficial to promote the plant's adaptive adjustments at the structural and physiological levels. For example, under this stimulus, the plant stems may tend to be thicker and more resilient, and the roots may grow in a deeper and wider direction to enhance anchoring ability. The overall stability of the plant under the impact of water flow or wind and waves may be enhanced, and the probability of lodging or breakage may be reduced to a certain extent.

[0052] Based on this, the structural combination of the guide plate 421, the bending plate 422 and the extension plate 423 allows the water flow sprayed from the water pipe 414 to have a path for reuse after contacting the smooth surface 3221. Through the cooperation between artificial disturbance and the natural adaptability of plants, it has a strong promoting effect on the ecological restoration process of submerged vegetation.

[0053] In some implementations, as shown in Figures 3 and 4, the multifunctional ecological enclosure for restoring submerged vegetation in lakes also includes a power supply mechanism 5. The power supply mechanism 5 is located on the plug-in rod 1 and is electrically connected to the supplementary lighting mechanism 3, so that the supplementary lighting mechanism 3 still has a stable energy source in environments where the lake water is relatively remote and the power supply is insufficient.

[0054] For example, the power supply mechanism 5 includes a solar panel 51 and a battery 52. ​​The solar panel 51 is located at the top of the plug rod 1. Since the top position is usually relatively unobstructed, it can receive solar radiation energy from above to a greater extent and output electrical energy through photoelectric conversion. Furthermore, the battery 52 is installed in the inner cavity of the plug rod 1, and the battery 52 is electrically connected to the solar panel 51 and the supplementary lighting mechanism 3. The arrangement in the inner cavity can obtain better structural protection, avoid damage caused by external water impact or floating object collision, and also help reduce the degree of influence of temperature changes on the battery 52.

[0055] It is understood that the solar panel 51, battery 52, and supplemental lighting mechanism 3 are all electrically connected. The solar panel 51 charges the battery 52 when there is sufficient sunlight, and the battery 52 supplies power to the supplemental lighting mechanism 3 when there is insufficient sunlight or at night. This allows the supplemental lighting mechanism 3 to maintain light output at different times, ensuring a stable light environment for submerged vegetation even under conditions of insufficient sunlight, large water depth, or turbid water, thus promoting continuous photosynthesis. The plug-in rod 1 serves as the installation location for the power supply mechanism 5. Its internal space can accommodate the battery 52 and necessary wiring paths. The hollow, enclosed structure isolates the electrical components from the external water, reducing the probability of electrical failures due to water immersion. Furthermore, the height difference between the high position of the solar panel 51 and the internal position of the battery 52 creates a more compact vertical arrangement of the overall power supply structure, reducing the impact of the power supply mechanism 5 on the overall stability of the enclosure.

[0056] Through the above structural coordination, a relatively continuous energy cycle path is formed between light energy collection, energy storage and light source output, thereby enhancing the sustainability of the supplementary lighting mechanism 3 under the condition of no external power supply, which has a positive effect on maintaining the long-term stable growth of submerged plants.

[0057] For example, the water pump 411 is also electrically connected to the battery 52.

[0058] In some embodiments, referring to Figures 3 and 4, the top of the plug rod 1 is provided with a horizontal mounting plate 6, and two solar panels 51 are inclinedly mounted on the mounting plate 6. It is worth noting that "inclined mounting" here means that the solar panels 51 form a fixed tilt angle relative to the mounting plate 6, so that the solar panels 51 are not in a horizontal state, but are facing the sky at a certain angle, so as to obtain a relatively ideal light-receiving area during a longer sunshine period.

[0059] For example, the cross-sectional shape formed by the mounting plate 6 and the two solar panels 51 is an isosceles acute triangle, and a ventilation opening 61 is provided through the mounting plate 6, which is located directly below the vertical projection formed by the two solar panels 51.

[0060] It is understandable that, due to the symmetrical and inclined arrangement of the solar panels 51, a roof-like shading structure is formed above, naturally shielding the area directly below, thus preventing the ventilation openings 61 from being directly exposed to the rainfall area during cloudy or rainy weather. The ventilation openings 61 provide an airflow path for the hollow structure, mitigating the risk of heat accumulation in the enclosed space of the battery units 52, while their location below the projection area of ​​the solar panels 51 reduces the probability of rainwater entering the insertion rod 1 to some extent.

[0061] In addition, the two tilted solar panels 51 can obtain light energy under different solar azimuth angles, making the absorption of light energy more balanced throughout the day, without relying on incident light from a single direction.

[0062] For example, rain shields can be installed on the sides of the two solar panels 51 to block rainwater from splashing in from both sides, making the top space more protective and also providing lateral obstruction to the ventilation openings 61. This allows the overall structure to maintain ventilation requirements while having good waterproof and light-blocking performance, which is beneficial to protecting the safety and lifespan of the internal battery 52 unit.

[0063] In some embodiments, referring to Figures 3 and 4, a perch 7 is provided on top of the joint of the two solar panels 51, which is used for birds to rest or perch.

[0064] For example, the perch is constructed of a light-transmitting glass plate.

[0065] It is understandable that, since the solar panel 51 is arranged at an angle, the perch 7 extends along the joint of the solar panel 51 and is located above it, allowing birds to briefly perch or stand in this position. This structurally endows the ecological enclosure with bio-friendly properties, which is beneficial for attracting bird activity and enhancing the diversity of the aquatic ecosystem. Simultaneously, the perch 7 is made of glass, whose light-transmitting properties allow natural light to penetrate along the incident direction of the perch 7 and reach the surface of the solar panel 51 below. This is beneficial for the solar panel 51 to absorb and convert light energy, thereby maintaining the stable operation of the power supply system. In rainy conditions, the perch 7, located above the solar panel 51 and forming a certain shading angle, allows rainwater to preferentially slide off along the outer edge of the perch 7, reducing the probability of rainwater directly adhering to the surface of the solar panel 51. This helps to reduce the adverse effects of water residue on power generation efficiency. In addition, the glass plate has a relatively smooth surface and weak surface adhesion. When birds produce droppings while roosting, combined with rainwater or natural flushing conditions, the droppings are more likely to detach from the surface of the perch 7, thereby reducing the possibility of long-term adhesion of pollutants. Overall, this is beneficial to the long-term use and maintenance of the ecological enclosure structure in the outdoor environment.
