Tidal power generation device with adjusting function

Abstract

The invention discloses a tidal power generation device with an adjusting function, and relates to the technical field of new energies. The tidal power generation device comprises a first shell, two grooves are formed in the inner wall of the first shell, two sliding devices are fixedly connected to the inner walls of the grooves, and the opposite surfaces of the two sliding devices are fixedly connected with the left side surface and the right side surface of an annular plate correspondingly; and a first sliding groove is formed in the inner wall of the annular plate, two first sliding blocksare slidably connected to the inner wall of the first sliding groove, and the opposite faces of the two first sliding blocks are fixedly connected with the left side face and the right side face of amovable plate correspondingly. According to the tidal power generation device with the adjusting function, through the combined action of a motor, a third rotating shaft, a take-up reel, a steel wirerope, a second sliding block, an annular sliding groove, the annular plate, a sliding rod, a sliding sleeve and a spring, the height of a propeller is adjusted, so that the propeller is located at aproper position according to the actual situation of the ocean tide level, and therefore, the tidal power generation efficiency is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a tidal energy power generation device with an adjustment function. Background technique [0002] The world's ocean energy reserves are about 75 billion kilowatts. Such a huge energy resource is thousands of times the current world's total energy consumption. The potential for development and utilization is huge. Using ocean energy to generate electricity has become a hot spot in the international new energy market. There are relatively abundant ocean energy resources near the coast and islands of mainland China, with a total reserve of more than 800 million kilowatts. [0003] Ocean tidal energy refers to the potential energy and kinetic energy of seawater formed by the periodic rise and fall of seawater. my country's coastline is long and tortuous, and there are relatively rich marine tidal energy resources, with a reserve of about 190 million kW and an annual power generat...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a tidal power generation device with an adjustment function, which solves the problem that most of the current tidal power generation devices are usually fixed, and it is not convenient to adjust the height of the propeller, because the tidal potential energy of different heights The difference between the propellers cannot be located in a suitable position, thus reducing the power generation efficiency of the tidal power generation device to a certain extent.
