Horizontal shaft energy concentrating fan for wind and wave combined power generation and working principle thereof

Abstract

The invention relates to a horizontal shaft energy concentrating fan for wind and wave combined power generation. A radial frame, an outer circular frame and an inner circular frame form a conical impeller with a wind gathering function. A conical air guide plate improves the wind efficiency, a steel cable increases the firmness of the impeller and a hydraulic pump is directly driven by a fan. Theworking principle is as follows: the radial frame, the outer circular frame and the inner circular frame form a conical impeller surface, and then a three-dimensional impeller is formed by the conical impeller surface, the conical impeller and the steel cable. The three-dimensional impeller is higher in strength than a conventional plane impeller. The concave surface of the conical impeller facesthe wind, the pressure difference of the front and back of the impeller can be increased and the efficiency is improved. The conical air guide plate guides the wind in the center of the impeller toward blades, and thus the efficiency is improved again. The horizontal shaft energy concentrating fan for the wind and wave combined power generation is used in combination with a deep sea wave power generation device so as to omit a yawing device, a buoyancy frame, an oil tank, an oil circuit, a hydraulic motor and a generator, thus a lot of devices are omitted and the cost is reduced, the efficiency is improved, and the horizontal shaft energy concentrating fan has good economic and social benefits after popularization and application.

Description

technical field [0001] The invention belongs to the technical field of wave power generation, and in particular relates to a horizontal-axis energy-gathering fan for combined wind-wave power generation and its working principle. Background technique [0002] Our country has a vast ocean, and the use of wave power generation is an important measure to conquer nature and use natural resources to develop energy construction. [0003] The Chinese patent with the application number CN201310210736.7 discloses a deep-water wave power generation device. It is provided with 7 sets of impeller brackets on the upper end of the buoy frame. The impeller brackets are equipped with impellers. Both sides of the impellers are provided with large toothed discs. A hydraulic pump is arranged on the upper side of the toothed plate, and a small gear is arranged on the hydraulic pump, and the pinion gear of the hydraulic pump meshes with the large toothed plate. The right front end of the motor i...
