Abstract

The invention provides a low transparency water submersible vegetation light-filling device and method. The device comprises an energy supply device, a control device, a fixing device, and a lightingdevice; the energy supply device is disposed on the bank and connected to the illumination device for powering the illumination device; the control device is connected to the energy supply device to control the energy supply device to open and close; the fixing device fixes the lighting device to the underwater area to be illuminated; the lighting device comprises an LED panel, an LED lamp set disposed on the LED panel, and a waterproof lamp cover; wherein, the LED lamp group is composed of a red LED, a blue LED and an ultraviolet LED. The light-filling device is highly efficient, energy-saving, environmentally-friendly and safe, and can effectively provide submerged plants with the wavelength light and light intensity required for normal growth, and promote the recovery of submerged plants.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of water bodies, and in particular relates to a light supplementing device and method for submerged plants in low-transparency water bodies. Background technique [0002] Surface water pollution is a ubiquitous environmental problem. The main cause of water pollution is the enrichment of nutrients such as nitrogen and phosphorus in the water, the abnormal growth of algae, the deterioration of water color, the significant decrease in transparency, and the disappearance of a large number of submerged plants. Submerged plants refer to the plants whose roots are in the mud, the stems and leaves are all submerged in the water, and the flowers only emerge from the water when they bloom. Submerged plants have a unique ecological niche in the aquatic ecosystem and play important ecological functions: absorb nutrients in water, increase oxygen content in water and sediment, reduce water vel...

AI Technical Summary

Problems solved by technology

Early plants mostly used white light for supplementary light, and the effects of different wavelengths of light on plant photosynthesis were greatly different. Among them, 400~520nm (blue light) and 610~720nm (red light) contributed the most to photosynthesis, and other wavelengths The impact of light on plant growth is negligible, so the proportion of ineffective light in white light is high, and a considerable amount of energy is transferred to the environment in the form of thermal effect, the utilization rate of light energy is low, and the efficiency of light supplementation for plants is low.

Patent CN106830342A discloses a submerged plant light supplement equipment. A steel wire cage is installed outside the supplement light, which will produce two negative effects: the surface of the supplement light is easy to attach biofilm, which affects the permeability of the supplement light and reduces the supplementary light. Light efficiency, secondly, under the action of water flow or wind and waves, the leaves of submerged plants will beat frequently, or even wrap around the wire cage, causing mechanical damage to the plant leaves

None of the existing related patents design submerged plants to restore water depth. When the water depth is too high, even if artificial light sources are supplemented, submerged plants cannot form a stable self-successive community, which has limited improvement of the water environment.
