Embodiment Construction

[0016] figure 1 , 2 A double reverse folded transverse axis tidal energy turbine is shown. In the figure, the impeller 1 of the water turbine is connected to the generator 7 through the connecting rod 4, the steering knuckle 5 and the speed-increasing gearbox 6, and the tidal current can rotate the impeller 1 to drive the generator 7 to generate electricity. A set of impeller 1, connecting rod 4, steering knuckle 5 and speed-up gearbox 6 are respectively provided at both ends of the generator 7, and the speed-up gearbox 6 at both ends of the generator 7 is fixed on a common base 10, and the base 10 Protective cover 8 is provided on it, and the two ends of protective cover 8 are respectively provided with a shaft seal 9 of the input shaft of speed-increasing gearbox 6 . The foundation 10 is installed on the pillar 12 by means of the thrust bearing 11, and the pillar 12 is fixed on the cement foundation 14 of the seabed by the anchor bolt 14a. The impeller 1 adopts four blade...

Abstract

The invention relates to a bi-reverse folding-type cross shaft tidal stream energy hydroturbine belonging to the technical field of electricity generation by utilizing tidal stream energy. In the bi-reverse folding-type cross shaft tidal stream energy hydroturbine, either end of a generator is provided with an impeller, a connecting rod, a steering joint and speed-increasing gearboxes, wherein the generator and the speed-increasing gearboxes at both ends are fixe on a common base which is mounted on a supporting column by the aid of a thrust gearing in a rotating mode, the supporting column is fixed on the cement basis of a seabed, and the blades of the impeller, the connecting rod and the supporting column adopt folding structures. The tidal stream energy hydroturbine reduces the size of the whole device and is convenient to transport by effective folding, avoids dismounting among all parts, decreases the mounting cost of the seabed by more than 50 percent than the traditional cost and prolongs the service life of the hydroturbine by longer than 5 years.

Description

technical field [0001] The invention relates to a double reverse folded horizontal axis tidal current energy water turbine, which belongs to the technical field of utilizing tidal current energy to generate electricity. Background technique [0002] As a clean and renewable energy source, ocean energy is not only rich in resources, but also has little impact on the environment. At present, the theoretical total amount of renewable ocean energy resources in the world is 766,000GW, and the development prospects are very promising. my country has a long coastline and a vast sea area, and has abundant ocean energy reserves. The exploitable ocean energy resources include: tidal current energy, tidal energy and wave energy, etc. Among them, the theoretical average power of tidal current energy is 13940MW. Due to its strong predictability, tidal current energy has greater advantages than wave energy in stably providing electricity. At the same time, compared with the use of tidal ...
