Overwater protection device with wave dissipation and seawater desalting functions

Abstract

The invention discloses an overwater protection device with wave dissipation and seawater desalting functions. The overwater protection device comprises upper and lower air chamber, a lower floating body, a turbine machine, a plant model, a vacuum pump, a filtering pipe, a unidirectional air feeding valve and a unidirectional intake and vent valve. When seawater passes through the device, the plant model is used for reducing wave energy through turbulent fluctuation in a flow direction and a vertical direction respectively, so as to realize the effect of wave dissipation and shore protection.A root, stem and leaf structure of the plant model can be used for generating inner crown laminar flow to promote the diffusion of nutrients of a water body and also can be used for enhancing the exchange of an offshore water body to ensure the stability of an offshore ecological system. Meanwhile, the device sufficiently utilizes an ocean wave resource; when waves are transmitted to the device, air pressure in the device is changed through wave surface floating and wave energy is used for replacing electric energy to provide power to a vacuum pump, so that the seawater desalting aim is realized. According to the overwater protection device, ecological shore protection engineering and a seawater desalting technology are combined, a freshwater resource lacking problem is solved and the stability of the offshore ecological system is ensured.

Description

technical field [0001] The invention relates to the field of coastal engineering, in particular to a water protection device with functions of wave dissipation and seawater desalination. Background technique [0002] With the rapid increase of the global population and the deterioration of the water environment, the world will face a shortage of fresh water resources. According to reports, the global demand for fresh water continues to grow, and will triple by 2050, and the problem of fresh water supply is imminent. At present, countries around the world have initially alleviated the shortage of fresh water resources through the construction of large reservoirs and cross-basin water transfer projects, but these measures have not increased the total amount of fresh water resources and cannot fundamentally solve the problem of fresh water supply. Compared with the scarcity of fresh water resources, the world's seawater reserves are huge. In my country, the coastline is narro...

Problems solved by technology

The disadvantage of the semi-submersible wave-dissipating device mentioned in this patent is that the semi-submersible wave-dissipating structure cannot reduce the wave energy above the still water surface, and its wave-dissipating units are densely distributed along the water depth direction, which affects the exchange of the upper water body
