Embodiment Construction

[0032] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0033] Such as Figure 1-2 As shown, the horizontal axis tidal current energy turbine provided by the present invention includes a blade 1, a hub 2, a digital flow velocity and direction meter 3, a vertical support 4, a cabin support 5, a radial bearing 6, a cabin connecting shaft 7, a cabin 8, and a guide rail support seat 9. Linear guide rail 10, slider 11, rack 12, gear 13, driving device 14, driving device bracket 15, counterweight 16 and limit block 17. Among them, the linear guide rail 10, the slider 11, the rack 12, the gear 13, the driving device 14, the driving device bracket 15, the counterweight 16 and the limit block 17 form an active pitch adjustment device.

[0034] The blades 1 are evenly distributed on the side of the hub 2 as the main device f...

Abstract

The invention belongs to the technical field of renewable energy development, and in particular relates to a horizontal-axis tidal current energy water turbine. It includes blades, hubs, and nacelles, and the blades are fixedly connected to the first end of the nacelle through the hubs. It also includes a digital flow rate and direction meter and an active pitch adjustment device for adjusting the pitch state of the horizontal-axis tidal energy turbine; the digital flow rate and direction meter is fixed on the wheel hub. Front end; the active pitch adjustment device is connected to the second end of the nacelle through the guide rail support seat, the active pitch adjustment device includes a linear guide rail, a driving device and a counterweight, the linear guide rail is arranged above the guide rail support seat, and the driving device is arranged on the counterweight On the side of the block, the counterweight is driven to make a reciprocating linear motion along the linear guide rail, so that the sweeping plane of the blade is perpendicular to the incoming flow direction of the tidal current. The horizontal axis tidal current energy turbine ensures that the sweeping plane of the blade is always perpendicular to the incoming flow direction, and can utilize the tidal current energy to the greatest extent.

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...
