Fresh water flood control equipment utilizing seawater salinity difference energy

Abstract

The invention relates to the technical field of seawater salinity difference energy. The invention further discloses fresh water flood control equipment utilizing the seawater salinity difference energy. The equipment includes a shell, wherein the bottom of the shell is movably connected with a buoyancy spring; a sliding groove is formed in the buoyancy spring; the surface of the sliding groove isslidably connected with a screw. The upper end of the screw rod is movably connected with a power generation wheel; fan blades are movably connected to the surface of the power generation wheel; buffer springs are movably connected to the surfaces of the fan blades, a supporting plate is movably connected to the tops of the buoyancy springs, a lifting plate is fixedly connected to the surface ofthe supporting plate, a permeable membrane is fixedly connected to the surface of the lifting plate, a conveying pipe is fixedly connected to the surface of the permeable membrane, and a flow dividingpipe is fixedly connected to the end, away from the permeable membrane, of the conveying pipe. The buoyancy springs float upwards, push the lifting plates to move upwards through the supporting plates and extend out of the entrances and exits, then the height of the dam is increased, fresh water is continuously led out of the reservoir, and therefore the effect of conducting flood diversion and embankment prevention through salinity gradient energy is achieved.

Description

technical field [0001] The invention relates to the technical field of seawater salinity difference energy, in particular to a freshwater flood control device utilizing seawater salinity difference energy. Background technique [0002] With the development of human civilization, the non-renewable energy on the earth is gradually exhausted, and the normal natural environment is also destroyed when the energy is excavated. Therefore, flood disasters often occur in some areas. People have brought renewable water energy; people's use of water energy can help slow down the loss of non-renewable energy. [0003] In the prior art, in order to reduce the damage caused by floods to people's property, the way of building dams is often used to deal with it, and the construction of dams can only block the flood but cannot drain it, and the symptoms are not cured. The potential energy of the rising water level cannot be utilized, resulting in energy waste and increasing the pressure on ...

[0003] In the prior art, in order to reduce the damage caused by floods to people's property, the way of building dams is often used to deal with it, and the construction of dams can only block the flood but cannot drain it, and the symptoms are not cured. The potential energy of the rising water level cannot be utilized, resulting in energy waste and increasing the pressure on the surface of the embankment. Therefore, a freshwater flood control device that uses seawater salinity difference energy came into being.
