Abstract

The utility model discloses a wind power generation device. The wind power generation device comprises a wind collecting scoop, a wind guiding pipe, an energy conversion device and a generator, wherein the closing-in end of the wind collecting scoop is connected to a wind inlet of the energy conversion device through the wind guiding pipe, and the energy conversion device is connected with the generator in a transmission mode. According to the wind power generation device, power of wind blowing to a wind wheel is increased through the wind collecting scoop, influence caused by the natural wind speed on operation efficiency of the wind power generation device is reduced, the time of maximum-efficiency operation of the wind power generation device is prolonged, the situation that the output power is ensured in the mode that the rated power of the wind power generation device is increased is not needed, the requirement for the diameter of the wind wheel is reduced, the structure is simple, and small-scale use is facilitated.

Description

A kind of wind generating unit

Technical field

The utility model relates to field of generating equipment, is specifically related to a kind of wind generating unit.

Background technique

A long time ago, people just utilize windmill that wind energy is converted to mechanical energy, are drawn water, the work such as flour milling; Now, the mechanical energy that people produce windmill is converted to electric energy and uses, and as a kind of clean renewable energy sources, wind energy more and more is subject to the attention of countries in the world.Existing wind generating unit comprises wind wheel, generator and steel tower, wind wheel is installed on the steel tower top, wind energy is converted to mechanical energy, be converted to electric energy output by generator again, but the operational efficiency of existing wind generating unit is subject to the nature air speed influence very large, and the rotor diameter of the higher wind generating unit of rated power is larger, has restricted the development of civilian wind generating unit.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of wind generating unit, can solve existing wind generating unit output power and be subject to the nature air speed influence large, and power more the high request rotor diameter is larger, restrict the problem of civilian wind generating unit development.

The utility model is achieved through the following technical solutions:

A kind of wind generating unit, comprise wind collection scoop, induced air pipe, energy conversion device, generator, and the closing in end of described wind collection scoop is connected to the intake grill of energy conversion device by induced air pipe, and described energy conversion device and generator are in transmission connection.

The further improvement of the utility model scheme is, described energy conversion device comprises housing, in described housing, impeller is installed, and described impeller is coaxially connected with drive wheel, described drive wheel and generator transmission.

The further improvement of the utility model scheme is that the inwall of described wind collection scoop is provided with screw thread.

The further improvement of the utility model scheme is that described induced air pipe inwall is provided with screw thread.

The utility model advantage compared with prior art is:

One, blow the wind-force to wind wheel by the wind collection scoop increase, reduce the impact of nature wind speed on the electricity generating device operational efficiency, extend the time of electricity generating device maximal efficiency operation, do not need to take the mode that increases electricity generating device rated power to guarantee output power, reduced the requirement to rotor diameter;

Two, simple in structure, be convenient to miniaturization and use.
