Embodiment Construction

[0017] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0018] The overall structure and layout of the vertical axis tidal current power generation device: the gravity tower base 1 and the tower column 2 are connected by a universal ball joint 3, the wind and wave resistant dish-shaped nacelle 4 is installed on the top of the tower, and the outer edge of the dish-shaped nacelle Distribute four anchor chain eyelets 5 and use cables 6 to connect the buoy 7 and the anchor to the anchor. 8. The tower column as the main structure is supported by the cable at the upper end and the gravity tower column base at the lower end to resist external forces. The main shaft of the water turbine 9 is set on the tower column. The lower end of the main shaft adopts plum blossom rubber water lubricating bearing 10, and the upper end of the main shaft adopts radial and axial combined rolling bearing 11, which is used to bear the gravity and...

Abstract

The invention provides a high-power vertical shaft tidal generating set. A gravity type pylon base (1) is connected with a pylon (2) through a universal ball hinge (3); an engine room (4) is arranged at the top end of the pylon; the periphery of the engine room is distributed with ropes (6) used by anchor chain plate holes (5) for connecting a floating bucket (7) and an anchor chain on an anchor (8); a water turbine spindle (9) is sleeved on the pylon, and both ends of the water turbine spindle are provided with bearings; water turbine blades (12) are uniformly distributed and fixed on a shaft hub (14) of the spindle through a spoke (13); an umbrella-shaped gear (15) on the spindle is engaged with a small umbrella-shaped gear (17) on a shaft of a generator (16) in the engine room; sealing shaft sleeves (18) are additionally arranged at the upper end of the spindle, on the lower wall of the engine room and on the pylon; and the base and the universal ball hinge are connected through a flange plate (19). The high-power vertical shaft tidal generating set provides clean renewable energy sources required by production and life for coastal areas, numerous islands and remote areas and particularly for residents on islands which cannot be covered by the national grid, and has positive social benefit.

Description

technical field [0001] The invention relates to a hydroelectric power generation device, in particular to a device for generating electricity by using tidal currents. Background technique [0002] The tidal current power generation device is an ocean energy power generation device that uses the water turbine to absorb the kinetic energy of the water flow and generate shaft torque to drive the generator to work. Years of research experience have shown that after the maximum flow rate of tidal current energy is determined, the power generation device must reach the rated power of a single unit, and the scale of its turbine will increase with the increase of the rated power generation. Like a wind power plant, a 1.2Mw wind turbine has an impeller diameter of 63m and a tower height of about 70m. Such a huge overall structure is quite difficult to install on land in terms of structural strength and installation construction. The same huge tidal current energy It is more difficul...
