Wind gathering device for improving efficiency of air blower or wind driven generator

Abstract

The invention discloses a wind gathering device which can increase air quantity and improve the efficiency of an air blower, and belongs to the technical field of wind energy utilization. The device is characterized by comprising an air blower or a wind driven generator, one or more than one wind gathering surface, and one or more than one support frame which is used for supporting the wind gathering surface and stabilizing the wind gathering surface; a wind wheel, a driving system, a power generator and a machine head seat are arranged on the wind gathering surface or the support frame; and the support frame is arranged on a round track.

Description

1. Technical field [0001] The invention belongs to the technical field of wind energy utilization, and is especially applicable to the technical fields of wind power machinery and wind power generation. 2. Background technology [0002] With the rapid development of the world economy and fierce competition, new energy power generation technology, especially wind power generation technology, has attracted more and more attention from all countries in the world. At present, the installed capacity of wind power in the world has reached 4.9 million kilowatts, and it is still growing at an average annual rate of 60%, reflecting a new trend in the development of international electric power. my country has abundant wind energy resources, and foreign mature technologies can be used for reference. The conditions for large-scale development of wind power have been met and should be actively developed. However, at present, the high cost of wind power has hindered the further developm...

Problems solved by technology

It has 3 deficiencies: 1: Its gradually expanding cylinder is a whole conical cylinder; 2: It is to install a wind machine near the entrance in the cylinder, which can be known from its theoretical basis and specific content , its wind machinery is completely inside its barrel; such a structure seems feasible in theory, but its disadvantages can be found in practical applications. The volume is too large. If it is applied to a small computer, although its power generation efficiency can be improved, but because of its large size, the disadvantages brought about by the increase in material costs, engineering costs, and operating costs are greater than the increase in power generation efficiency. The benefits that come; for example, the power generation efficiency can be increased by 50%, but the cost has doubled. In this case, it is better to directly use two sets of power generation equipment. The power generation efficiency has also increased by 1 times, certainly better than improving 50%; If applied on the large wind turbine, with the em
