Embodiment Construction

[0011] like figure 1 , 2 , 3, it consists of a main wheel 1 and N auxiliary wheels 2, and N auxiliary wheels 2 are at least one. The angle between the axis of the windmill should generally be greater than 90 degrees and less than 120 degrees, which is conducive to the approach of the center of gravity of the windmill to the tower. The main wheel 1 is fixed on the main wheel shaft 5 through bearings; The teeth on 4 point to the center of the main shaft 1, and a central toothed plate 3 is fixed on the main wheel 1, and the secondary wheel 2 is meshed with the main wheel 1 through the gear 8 on it. The specific connection method is: the gear 8 of the secondary wheel 2 One side of the main wheel 1 is meshed with the ring gear 4 on the main wheel 1, so that the wind force obtained by the secondary wheel 2 acts on the outer edge of the main wheel 1 to increase the power of the main wheel 1, and the other gear 8 of the secondary wheel 2 The symmetrical side is meshed with the centr...

Abstract

The invention discloses a multi-impeller wind power generation windmill, and relates to a wind power generation impeller, in particular to a multi-impeller wind power generation windmill, which mainly solves the problems that an impeller blade is difficult to start, high in cost and easy to break due to being too long, and potential safety hazard exists because the known wind power generation windmill is only provided with one impeller. The wind power generation impeller is composed of a main impeller and N auxiliary impellers, wherein the auxiliary impellers are connected with the main impeller in a meshing manner through gears on the auxiliary impellers; and an auxiliary impeller shaft is connected with a main impeller shaft through a connecting rod. With the adoption of the multi-impeller wind power generation windmill, the diameter of a wind wheel can be shortened, the length of the blade can be shortened, the gravitational potential energy of the main impeller and the auxiliary impellers is transformed into the kinetic energy; and a spider gear structure is formed by the main impeller and the N auxiliary impellers, so that the transmission ratio is high, the utilization rate of the wind energy is high, the manufacturing cost of the wind wheel can be saved, and the safety is improved, therefore the efficiency and the benefit of wind power generation are improved.

Description

technical field [0001] The invention relates to a wind power generator impeller, in particular to a multi-wheel type wind power generator windmill. Background technique [0002] It is known that the wind turbine has only one impeller, which causes the impeller blades of high-power wind power generation to be too long. If broken, there are potential safety hazards, low efficiency, and high power generation costs, which affect the popularization and application of wind power generation. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned shortcomings, and propose a multi-wheeled wind power generation windmill device that can reduce the diameter of the impeller at the same power, use the secondary wheel to assist the main wheel, and is easy to start, high in power generation efficiency, and low in manufacturing cost. . [0004] The technical solution of the present invention is: the impeller of the multi-wheel wind power...
