Description

Technical Field

[0001] The present invention relates to the technical field of natural lake shoreline protection, and in particular to a natural lake shoreline energy recovery and wave-breaking device, system and method. Background Art

[0002] In the context of social development today, the ecological environment of rivers and lakes in my country is facing unprecedented challenges. In particular, the shoreline erosion of medium and large lakes has become an important issue affecting the ecological security of lakes and the quality of regional water environment. Wind and wave erosion, as the main cause of lake shoreline degradation, not only aggravates the erosion of earthwork, but also causes a decrease in water transparency, deterioration of the living environment of submerged vegetation, and destruction of shallow wetland ecosystems. These problems have greatly weakened the natural recovery capacity of lake ecosystems, and human intervention is urgently needed for ecological restoration.

[0003] In the ecological restoration project of lake shorelines, wave-proof measures are a key link to ensure the gradual stabilization of the ecosystem. Existing wave-proof technologies are mainly divided into soft enclosures and hard enclosures. Among them, the traditional soft enclosure, that is, the method of suspending geotextiles by floats, can reduce the impact of small waves on the shoreline to a certain extent, but its energy dissipation effect is limited, and it seems to be powerless under conditions of larger winds and waves. In addition, the geotextiles of soft enclosures are easily damaged, have high maintenance costs, and are not easy to recycle, resulting in high overall costs, which is not conducive to large-scale promotion.

[0004] The hard enclosure technology, which uses earth to build ridges, can effectively block wind and waves and protect the coastline from erosion. However, its construction process involves filling the lake with earth to create land, which not only conflicts with existing water conservancy management requirements, but may also have an adverse impact on the ecological connectivity of the lake, limiting its application in actual engineering.

[0005] In addition, it is difficult to recycle the energy generated by wind and waves in the above traditional methods, which to a certain extent causes a waste of natural energy resources. Summary of the invention

[0011] In one embodiment of the present invention, in the height direction of the mounting member, an end of the guide surface away from the water tank is located below an end of the guide surface close to the water tank.

[0012] In one embodiment of the present invention, the wave-breaking plate further comprises a water retaining plate, and the water retaining plate is arranged on two opposite sides of the guide surface and / or the water storage tank along a first direction.
