Embodiment Construction

[0021] Such as Figure 1 to Figure 3 As shown, the present invention is a combined device for power generation and seawater desalination using tidal energy, which includes a water turbine unit 1, a transmission group 2, a seawater desalination device 3 and a generator 4, and is characterized in that the device uses tidal energy to drive the water wheel 13 to rotate For seawater desalination and power generation, some intermediate processes are reduced to achieve the purpose of improving conversion efficiency.

[0022] When the tide rises or ebbs, a water level difference will be formed on both sides of the dam, so the water turbine unit 1 placed at the bottom of the dam will be driven to run. The water turbine unit 1 is formed by connecting several water wheels 13 through couplings 11. Wheel 13 is a hollow circular shaft, and its outer ring is provided with several blades (as image 3 ), the two ends of the water wheel 13 fix the bottom of the dam foundation through bearings ...

Abstract

The invention discloses a combined device for generating power through tidal power and desalinating sea water. The device is composed of a hydraulic turbine set, a transmission set, a sea water desalinating device and an electric generator, wherein the hydraulic turbine set is arranged at the bottom of a dam and formed by connecting a plurality of water wheels in series through couplings, each water wheel is a hollow cylinder, and a plurality of blades are arranged on the outer circle of each hollow cylinder. One end of the transmission set is arranged on an output shaft of the water wheels, the other end of the transmission set is arranged on a support on the dam, and linkage between the two ends is achieved through a transmission belt or a transmission chain. One end of an output shaft of the transmission set is connected with a booster pump to produce high-pressure sea water, then, fresh water is prepared by a membrane permeation assembly, and the other end of the output shaft of the transmission set is connected with the electric generator to generate electricity. The whole device integrates the tidal power and sea water desalination well, therefore, not only is the tidal power effectively utilized, but also the fresh water can be prepared, and the device is environmentally friendly, free from pollution and capable of being used in some coastal regions or islands where both water and electricity are in shortage.

Description

technical field [0001] The invention relates to a combined device for power generation and desalination of seawater by using tidal energy, in particular, it uses tidal energy in ocean energy to generate electricity and produce fresh water, and belongs to the field of tidal energy development and utilization. Background technique [0002] In nature, the undulating and never-ending sea contains huge energy, and using tidal energy to generate electricity has always been the goal pursued by people. Tidal energy is a renewable energy that cleans and pollutes the environment. The tide rises and falls every day, and it is repeated every week. It is inexhaustible and inexhaustible. The full development and utilization of tidal energy can not only save the increasingly depleted conventional energy and alleviate the severe shortage of resources, but also reduce pollution and protect the ecological environment on which human beings depend. Tidal energy refers to the potential energy ...
