Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0022] A window-type wind turbine wind wheel, including a main shaft sleeve 3, a hub 2, a blade 1, a blade shaft 4, and a stop rod 5, the wind wheel is installed on the main shaft of the generator through the main shaft, and the outer walls of both ends of the main shaft sleeve The hub is fixed symmetrically. The hub is composed of a plurality of coaxial and radially uniform support rods. Upper hinged blades; between the corresponding support rods on both sides of the inner side of the blade shaft, a baffle rod for limiting the swing angle of the blades is axially installed; in order to achieve the best windward angle and improve wind utilization efficiency, the blades on the support rods are installe...

Abstract

The invention relates to a window opening type wind wheel of a wind driven generator. The wind wheel is mounted on a generator spindle through a spindle and comprises a spindle sleeve, hubs, blades, blade shafts and stopping rods, wherein hubs are fixedly mounted on the outer walls of the two ends of the spindle sleeve in a symmetrical way; the hubs comprise a plurality of coaxial supporting rods which are uniformly arranged in a radial direction; the supporting rods on the two sides are in one-one correspondence with each other; a the blade shaft is axially mounted between each two corresponding supporting rods on the two sides; blades are hinged on the blade shafts; stopping rods for limiting swinging angles of the blades are axially mounted between the corresponding supporting rods on the internal sides of the blade shafts; and windward break angles are made in the blade mounting positions of the supporting rods. The window opening type wind wheel has the advantages of simple structure, high efficiency, low manufacturing cost, convenience in use, convenience for mounting, strong practicability and wide application range; defects of the traditional fixed blade, such as small wind energy stress surface, comparatively large resisting area and low efficiency, are changed; and an efficient wind wheel technology is provided for the wind power generation industry.

Description

technical field [0001] The invention belongs to the field of wind power generation, and relates to a generator, in particular to a wind wheel of a window-type wind power generator. Background technique [0002] Wind power generator is a clean energy that converts wind energy into mechanical energy and then into electrical energy. Wind power has good regenerative performance and no pollution. It is the focus of attention of countries all over the world. At present, wind turbines are mainly divided into horizontal-axis wind turbines and vertical-axis wind turbines. The wind-blocking blades are all rectangular frame or blade-shaped fixed structures, and their starting resistance and rotation resistance are relatively large, and the blades at the windward position Insufficient utilization of wind power. [0003] After searching, the following relevant patent documents were found: [0004] A universal wind generator (CN202073714U) utilizing the wind in nature, which is composed...
