Description

Technical Field

[0001] The present invention belongs to the technical field of silt management, and in particular relates to a submerged plant light compensation device and method based on silt management. Background Art

[0002] Submerged plants refer to large aquatic plants whose entire plant body is located below the water layer and survives fixedly. Their roots are sometimes underdeveloped or degenerate, and all parts of the plant body can absorb water and nutrients. The aerenchyma is particularly developed, which is conducive to gas exchange in the absence of air in the water. The leaves of this type of plant are mostly ribbon-shaped or filamentous, such as Vallisneria, Dermatophyte, Foxtail Algae, and Black Algae. In the natural process, a certain thickness of silt will accumulate on the bottom of the water. With the discharge of nitrogen and phosphorus nutrients, the influence of the original soil properties at the bottom gradually weakens and is gradually replaced by silt. Submerged plants can inhibit the resuspension of sediments in the water body, reduce the concentration of suspended particulate matter, promote the sedimentation of phosphorus in the water body, and thus improve the characteristics of sediments and reduce the deposition of silt on the bottom of the water.

[0003] Decreased water clarity is a sign of deteriorating water quality and a key factor limiting the growth of submerged plants. Changes in river transparency and insoluble phosphorus concentration are negatively correlated with incident light intensity. Once plants disappear from a specific area, sediment resuspension significantly limits plant regeneration in that area. Polluted river water has high suspended matter concentrations, low transparency and dissolved oxygen, and sunlight cannot reach below 30-50 cm. This prevents underwater photosynthesis for producers in the ecosystem, including plants and algae, exacerbating the accumulation of sediment at the bottom. Summary of the Invention

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Example 1:

[0043] The submerged plant light compensation device based on silt treatment includes:

[0044] A floating plate 1 is provided with a convex lens 11 for collecting sunlight. A diffuser 13 is provided corresponding to the convex lens 11. The diffuser 13 diffuses the light collected by the convex lens 11 to form diffused light.

[0046] Reflecting plate 4, the first parallel light beam is reflected by reflecting plate 4 to form a second parallel light beam;

[0047] The transparent tube 2 is rotatably connected to the floating plate 1. A groove 201 corresponding to the second parallel light beam is formed on the side wall of the transparent tube 2. The second parallel light beam passes through the groove 201 of the transparent tube 2 to form a divergent light beam.

[0048] The driving assembly is used to drive the transparent tube 2 to rotate. The diffuser 13 is a plane glass, and the end surface of the plane glass adjacent to the convex lens 2 3 is a frosted surface.

[0049] The groove 201 is an arc-shaped groove 201. There are multiple arc-shaped grooves 201, and the arcs of the multiple arc-shaped grooves 201 are different. In actual use, the floating plates 1 of multiple devices are fixedly connected.

[0050] The driving assembly includes a motor 7, a sun gear 81, a planetary gear 82, and a ring gear 21. The sun gear 81 is fixedly connected to the output shaft of the motor 7. The housing of the motor 7 is fixedly connected to the floating plate 1 through the connecting frame 5. The planetary gears 82 and the sun gear 81 are both rotatably connected to the gear frame 8. The gear frame 8 is fixedly connected to the connecting frame 5. The ring gear 21 is coaxially fixedly connected to the transparent tube 2. The planetary gears 82 are respectively engaged with the sun gear 81 and the ring gear 21.

[0051] The groove 201 is an arc-shaped groove 201 , and there are multiple arc-shaped grooves 201 . The curvatures of the multiple arc-shaped grooves 201 are different, and the curvatures of the multiple arc-shaped grooves 201 increase or decrease in sequence along the circumference of the transparent tube 2 .

[0052] There are multiple reflective plates 4, which are fixedly connected to the floating plate 1 via a connecting frame 5. The multiple reflective plates 4 form a conical reflective column, which is installed below the convex lens 2 3.

[0053] A mounting ring 6 is fixed on the side wall of the floating plate 1, and a light intensity sensor 601 corresponding to the reflector 4 is fixed on the lower end surface of the mounting ring 6. The light intensity sensor is used to detect the light intensity of the divergent light beam, and the light intensity sensor 601 is electrically connected to the controller.

[0054] A plane lens 41 corresponding to the first parallel light beam is provided in the transparent tube 2. The first parallel light beam forms a detection light beam through the plane lens 41. A light intensity sensor 2 91 is provided corresponding to the detection light beam. The light intensity sensor 2 91 is used to detect the light intensity of the detection light beam. The light intensity sensor 2 91 is electrically connected to the controller.

[0055] The submerged plant light compensation device also includes a light compensation component, which includes a solar panel 14, a battery, a compensation light source 9, and a light intensity sensor 3. The solar panel 14 is mounted on the upper end surface of the floating plate 1. The compensation power supply is fixedly connected to the floating plate 1 and corresponds to the position of the lens. The light intensity sensor 3 is used to detect the light intensity of sunlight.

[0056] Light intensity sensor 3 is electrically connected to the controller, compensation light source 9 is electrically connected to the controller via a driver, solar panel 14 is electrically connected to a battery, and the battery is electrically connected to compensation light source 9 via a driver. This converts sunlight energy into electrical energy and stores it in the battery. When sunlight is insufficient, the stored electrical energy is used to activate compensation light source 9 for supplemental lighting, ensuring effective light compensation.

[0057] An optical film is placed inside groove 201 to allow light of a specific wavelength to pass through. Different wavelengths of light affect plant growth patterns. For example, green light promotes the growth of young shoots, while red light inhibits growth. 100% natural sunlight inhibits the growth of water chestnut stems and leaves. Therefore, the appropriate optical film should be selected based on the plant species and growth stage.

[0058] Working process:

[0059] The light compensation mentioned in this application primarily provides irradiation compensation for fungi and submerged plants planted in silt. First, light compensation is provided for fungi in silt. For example, photosynthetic bacteria can photosynthesize in an oxygen-deficient environment with light, utilizing light energy to assimilate carbon dioxide or other organic matter. They can also degrade toxic substances such as nitrites and sulfides in water, serving as bait, purifying water quality, preventing diseases, and acting as feed additives. They also have a certain tolerance and decomposition capacity for toxic substances such as phenol and cyanide, possessing strong decomposition and conversion capabilities. They can also inhibit the resuspension of sediments in water bodies, thereby improving water quality and alleviating silt deposition. Secondly, light compensation is provided for submerged plants planted in silt. Increased light levels enhance the ability of foxtail algae seedlings to absorb phosphorus. Photosynthesis provides the energy necessary for plant phosphorus uptake, which in turn promotes the transfer of photosynthetic products and energy between photosynthetic and non-photosynthetic tissues. Underwater light compensation has a positive effect on the survival, growth, and leaf physiological indicators of Vallisneria seedlings. Under conditions of low-intensity light and high NH4+ concentrations, the starch content in hornwort and foxtail algae decreases, while under high-intensity light, the starch content increases. This allows more carbohydrates to detoxify NH4+, thereby enhancing the hornwort and foxtail algae's tolerance to high ammonium concentrations. Increased light levels enhance the submerged plants' tolerance to aquatic environments, allowing them to survive in harsher waters. Submerged plants can also decompose nitrogen, phosphorus, and other substances concentrated in silt, thereby improving water quality. Both of these methods have a minimal impact on the aquatic ecosystem and can avoid silt generated during dredging, thereby preventing secondary pollution.

[0060] The curvature of each groove 201 gradually increases and then decreases along the circumference of the transparent tube 2, with this change cycle encompassing one revolution of the transparent tube 2. Changing the curvature of the groove 201 is intended to alter the focal length of the concave lens structure, thereby changing the illumination range of the divergent light beam and improving the light diffusion capability of the light compensation device. This allows the light compensation device to provide light at various angles and intensities, effectively providing light compensation for submerged plants. In actual use, the light intensity parameter should be set based on the growth requirements of the specific plant.

[0061] The process of light compensation using sunlight is as follows: first, a light collection step; second, a light refraction step; third, a light reflection step; and finally, a light divergence step. In the light collection step, convex lens 11 collects sunlight, which is then diffused into the transparent tube 2 after passing through diffuser 13. In the light refraction step, convex lens 2 3 refracts the light obtained in the light collection step to generate a first parallel beam, the direction of which is parallel to the axis of the transparent tube 2. In the light reflection step, a plurality of reflective plates 4 reflect the first parallel beam to form a second parallel beam (the second parallel beam is perpendicular to the axis of the transparent tube 2). In the light divergence step, a rotation drive assembly drives the transparent tube 2 to rotate, and the second parallel beam passes through a concave lens structure (the concave lens structure is located at the groove 201 of the transparent tube 2) to generate a divergent beam.

[0062] The light is transmitted into the transparent tube 2 through the convex lens 11 and the diffuser 13, and the transmission direction of the light is adjusted by the convex lens 2 3 and the reflector. The light is diverged by the concave lens structure, so that divergent light beams with various light intensities and various illumination angles can be obtained in the circumferential direction of the transparent tube 2. The light compensation effect is good, and the problem of underwater fungi and aquatic plants being unable to grow normally due to insufficient light caused by poor water transparency is improved.

[0063] Rotating the transparent tube 2 makes the irradiation range of each divergent light beam different, diversifying the irradiation range, reducing the influence of obstructions on light compensation, increasing the light intensity on submerged plants and fungi in the bottom mud, promoting the decomposition of nitrogen, phosphorus, sulfur and other compounds in the water body and mud, inhibiting the resuspension of sediments in the water body, reducing the concentration of suspended particulate matter, promoting the sedimentation of phosphorus in the water body, thereby improving the characteristics of the sediment, reducing the resuspension of sediments, improving the transparency of the water body, and improving the water quality.

[0064] Example 2:

[0065] A method for applying the submerged plant light compensation device based on silt management according to the first embodiment includes the following steps:

[0066] To determine whether to turn on the supplementary light source, the light intensity sensor 3 detects the light intensity of the sunlight, and the light intensity sensor 2 91 detects the light intensity of the detection beam;

[0067] If the sunlight intensity is lower than the minimum sunlight intensity threshold, the supplementary light source is turned on;

[0068] If the sunlight intensity is lower than or higher than the sunlight intensity threshold, and the intensity of the detection beam is lower than the detection threshold when the supplementary light source is not turned on, the supplementary light source is turned on;

[0069] If the sunlight intensity is lower than or above the sunlight intensity threshold, and the intensity of the detection beam is higher than the detection threshold when the supplementary light source is not turned on, the supplementary light source is turned off. When there is sufficient sunlight, the sunlight energy is converted into electrical energy and stored in the battery. Then, when there is insufficient sunlight, the stored electrical energy is used to turn on the supplementary light source 9 for supplementary lighting, ensuring the light compensation effect.

[0070] Determine whether the divergent light beam is blocked;

[0071] S1. When the light intensity difference between the scattered light beams emitted by two adjacent grooves 201 detected by the same light intensity sensor 601 is greater than the blocking threshold, the process proceeds to step S2.

[0072] S2. If the light intensity difference between the scattered light beams emitted by two adjacent grooves 201 detected by the same light intensity sensor 1 601 is less than or equal to the error threshold, it is determined that the position corresponding to the light intensity sensor 1 601 is not blocked;

[0073] If the light intensity difference between the scattered light beams emitted by two adjacent grooves 201 detected by the same light intensity sensor 1 601 is greater than the error threshold, it is determined that the position corresponding to the light intensity sensor 1 601 is blocked.

[0074] The setting is coordinated with the change of the curvature of the concave lens, and the actual light intensity of the divergent light beam is detected by using a light intensity sensor 601 to detect whether obstruction occurs, so as to facilitate timely reminder to clean the outside of the transparent tube 2 to ensure the lighting effect. The same light intensity sensor 601 can be used for obstruction detection, with a simple structure, reducing equipment investment and operating costs.
