Wind wave resistant ecological floating island

Abstract

The invention relates to a wind wave resistant ecological floating island. The ecological floating island comprises a floating island body, wherein the floating island body comprises a main floating body, a first planting medium layer and a first plant layer planted on the first planting medium layer; the main floating body comprises an upper floating body above the water surface and a cofferdam floating body below the water surface; the upper floating body is ring-shaped while the cofferdam floating body is shaped like a skirt border; the bottom of the upper floating body is connected with the top of the cofferdam floating body; the upper floating body is arranged outside the first planting medium layer in a surrounding manner. Compared with the prior art, the ecological floating island has the advantages that the floating island can obtain high enough buoyancy and good wind wave resistance; the floating island is prevented from being attacked by wind wave and sinking and the overall stability of the floating island is improved; the floating island can achieve plant diversity, obtains good landscape effects, can become the habitat of various animals and is beneficial to building of a microenvironment ecological system.

Description

technical field [0001] The invention relates to the fields of water body purification and water surface beautification, in particular to a storm-resistant ecological floating island. Background technique [0002] In recent years, rivers, lakes, reservoirs, ponds and other water bodies have been polluted by the environment, resulting in eutrophication of water bodies and destroying the ecological balance of water bodies. At present, the application of ecological floating islands in water pollution control is attracting more and more attention. Ecological floating islands use the plants cultivated on them to remove pollutants such as nitrogen and phosphorus in polluted water bodies, inhibit the excessive growth of algae in water bodies, and at the same time It can beautify the water body landscape, and has the advantages of no need to occupy land, low cost and good restoration effect.

AI Technical Summary

Problems solved by technology

[0003] At present, the existing ecological floating islands still have the following problems: (1) Limited buoyancy: the existing ecological floating islands generally use foamed plastics or recycled plastics as basic materials. Although the production cost is relatively low, the buoyancy is limited and easy (2) Floating island plants are single: Floating island plants are an important part of the ecological floating island. They are not only the bearers of the ecological functions of the floating island, but also make the floating island The embodiment of the landscape effect, but the existing ecological floating island plant configuration is difficult to take into account the two major functions of landscape and ecology. In addition, due to the limited buoyancy, it is impossible to plant large plants, and most of the floating island plants cannot survive the winter, especially in winter weather. In colder northern regions, floating island plants need to be replanted in the second spring, which not only affects the landscape effect, but also increases maintenance costs; (3) The structure is not stable: traditional floating islands are usually connected by ropes, which is time-consuming and easy to fall apart , the ability to resist wind and waves is poor, it is difficult to resist extreme wind, heavy rain and big waves, and the floating island material polyethylene is easy to oxidize and decompose, thus shortening its service life
