Embodiment Construction

[0024] 1. In order to give full play to the best power generation capacity of the power generation unit during operation, corresponding high-performance piezoelectric materials can be selected to manufacture the power generation unit according to the specifications, models and technical parameters required by different application objects. The piezoelectric material in the power generation unit should have the effects of superconductivity, heavy pressure resistance, impact resistance and corrosion resistance.

[0025] 2. Seal and wrap single or several piezoelectric materials with high-performance elastic materials and press them into sheets. Inside each piece of high-performance elastic material, silver paste electrodes are screen-printed to form positive and negative circuits (the two ends are led out by external wires, and the wires should have good insulation, superconductivity, heavy pressure resistance, impact resistance and corrosion resistance) , forming a power genera...

Abstract

The invention relates to a hydraulic power generation technique by utilizing piezoelectricity principle. According to the principle of piezoelectric generation, the generating unit of the invention is made of a piezoelectric material; and the piezoelectric material in the generating unit should have the effects of high pressure resistance, shock resistance and corrosion resistance. The generating unit is installed underwater, and used for receiving the flow speed, fall impact and depth pressure of water. When the generating unit is subjected to the actions of flow speed, fall impact and depth pressure of water, the piezoelectric material is subjected to impact extrusion to continuously generate electric power. The electric power can be delivered to places in need of electric power through the electric power conversion and storage (delivery) circuit system. The invention can be widely used in places in contact with water, such as in riverbeds, ducts, channels, oceans, ship bottoms (sea gauge positions) and the like.

Description

1. Technical field [0001] The patented technology of the invention belongs to the technical field of hydropower generation, and can realize a hydropower generation technology utilizing the piezoelectric principle. 2. Background technology [0002] At present, there are two basic methods of power generation technology for hydropower stations in the world: one is to use small flow and high water pressure, and the other is to use large flow and low water level. These two methods have different problems and defects in terms of investment cost, construction period, safety maintenance, ecological environment, resettlement, and economic benefits. [0003] According to a report by China Central Television "First Time" on March 5, 2009, an Israeli company is researching a technology that turns the rolling traffic on the road into a power plant to provide people with the electricity they need for their daily lives. The Haifa, Israel-based Innova Technologies is developing a revolutio...
