Abstract

The invention belongs to the technical field of renewable energy source development, and particularly relates to a horizontal-axis tidal current energy water turbine. The horizontal-axis tidal currentenergy water turbine comprises blades, a hub and a cabin, the blades are fixedly connected with the first end of the cabin through the hub, and the horizontal-axis tidal current energy water turbinefurther comprises a digital flow-rate flow-direction meter and a driving pitching adjusting device used for adjusting a pitching state of the horizontal-axis tidal current energy water turbine. The digital flow-rate flow-direction meter is fixed to the front end of the hub. The driving pitching adjusting device is connected with the second end of the cabin through a guide rail supporting seat, thedriving pitching adjusting device comprises a linear guideway, a driving device and a balancing weight, the linear guideway is arranged above the guide rail supporting seat, and the driving device isarranged on the side surface of the balancing weight to drive the balancing weight to perform reciprocating rectilinear movement along the linear guideway, so that sweeping planes of the blades are perpendicular to the incoming flow direction of tides. The horizontal-axis tidal current energy water turbine ensures that the sweeping planes of the blades are always perpendicular to the incoming flow direction, and tidal current energy can be furthest used.

Description

technical field [0001] The invention belongs to the technical field of renewable energy development, in particular to a horizontal-axis tidal current energy water turbine. Background technique [0002] Energy is the basic guarantee of human society, and the growing economy has greatly increased human energy demand. At present, the energy consumed by human beings mainly comes from fossil fuels. The consumption of a large amount of fossil energy not only makes human beings face the problem of energy depletion, but also brings serious environmental problems. According to the 2010 statistical report of British Petroleum, the global oil reserves can be exploited by humans for more than 40 years, and the resulting ecological problems such as global warming, ozone destruction, and air pollution threaten the survival of humans and all living things. [0003] In order to further optimize the energy structure, the development of marine plot energy is of great significance. It is est...
