Automatic draining system and method suitable for point floating type wave energy power generation device

Abstract

The invention provides an automatic draining system and method suitable for a point floating type wave energy power generation device. The system comprises a floater system, an energy conversion system, a cable and a power free automatic draining system, wherein the floater system is connected to the energy conversion system for converting wave energy into electric energy, and the electric energyoutput end of the energy conversion system is connected to the cable; the power free automatic draining system comprises two linked L-shaped bent rods and a draining push plate, one ends of the two linked L-shaped bent rods are fixed to the floater system while the other ends of the linked L-shaped bent rods are fixed to the draining push plate, and the draining push plate is fixed to an inner cavity of the energy conversion system. According to the system, the draining link purchase and electric energy expenditure are saved, so that the operating cost is lowered. Meanwhile, the draining structure is simplified. The volume of the individual point floating type wave energy power generation device is reduced by means of the existing space of the power generation device, so that the quantityof power generation devices in unit area is increased.

Description

technical field [0001] The invention belongs to the technical field of renewable energy power generation, and in particular relates to an automatic drainage system and method suitable for point-floating wave energy power generation devices. Background technique [0002] Ocean wave energy refers to the kinetic energy and potential energy of ocean surface waves. The global wave energy reserves are huge. On every square kilometer of sea surface, fluctuating waves contain about 300,000 kilowatts of energy, and the wave energy available for development is about 3 billion It can be seen that wave energy has great development and application value. The exploitable amount of wave energy resources in my country is estimated to reach 12.84 million kW, and nearshore resources are mainly concentrated in Zhejiang, Guangdong, Fujian, Shandong, Hainan, Jiangsu and other places. Compared with the world's major wave energy resource-rich areas, my country's wave energy power density is not h...
