Suspension bed with water ecological restoration function

Abstract

The invention discloses a suspended bed with the function of water body ecological restoration, which belongs to the technical field of water body ecological restoration treatment. The suspended bed with water body ecological restoration function includes a light intensity adjustment system, a light intensity detector, a buoyancy ball, a lifting or lowering pull rope for the suspended bed, submerged plants and a planting bed. The system can use the light detector to monitor the light intensity around the submerged plants in time, and by comparing the light intensity required by the submerged plants set in the light adjustment system, the system can adjust the distance between the planting bed and the water surface, so that the light intensity Meet the growth needs of submerged plants. The invention has a simple structure, is easy to plant and harvest plants, and has low maintenance costs; it can precisely control the distance between the bed body and the water surface according to the light intensity in the water, and can meet the light conditions required for the growth and reproduction of submerged plants; by suspending the bed body in the water, It can be used in deep water, hard riverbed and low transparency water bodies, and has a wide range of applications.

Description

technical field [0001] The invention relates to a suspended bed with the function of water body ecological restoration, and belongs to the technical field of water body ecological restoration treatment. Background technique [0002] Since the reform and opening up, with the rapid development of my country's economy, nutrients such as nitrogen and phosphorus discharged into water bodies have increased rapidly, the pollution of natural water bodies such as lakes and rivers has become more and more serious, and the eutrophication of water bodies has become more and more severe. Problems such as the urban water supply crisis seriously restrict the sustainable development of my country's economy. Aquatic plants can absorb pollutants such as nitrogen and phosphorus in water through their roots and leaves for their own growth and reproduction, and then manually harvest aquatic plants to recover pollution from water bodies. Restoring the original submerged vegetation of the water bo...

Problems solved by technology

However, due to the turbidity of the water body, insufficient underwater light (not reaching the light compensation point of submerged plants), the hard bottom of the bed, and the rapid rise of the water level caused by heavy rain, it is difficult to construct an aquatic ecology with submerged plants as the main primary producers. The system is difficult

[0004] At present, the common planting and reconstruction methods of submerged plants are mainly direct planting of seedlings and direct cultivation of seeds. Both of these methods need to be buried in the bottom mud in the water. It is necessary to maintain an appropriate water level. If the water level is too high, the water pressure will increase, and the seedlings may break due to excessive water pressure. Planting is difficult. If the water level is too low, high-intensity sunlight may affect the growth and development of planted seedlings or seeds. Adverse effects; second, bottom mud planting is only suitable for soft bottom mud, and if the bottom mud of the water body is hard, submerged plants cannot be planted; third, when the water body environment changes, such as turbid water body, rising water level, insufficient light, etc., it is easy to cause The survival rate of submerged plants in the water body is low, and the ability to resist changes in the external environment is poor

The existing suspended bed has fixed the height of the suspended bed, and the grasp of the light intensity of submerged plants is not accurate. It often needs an external light source, which cannot make full use of natural light, resulting in complex structure and high cost, and is not suitable for field implementation.
