Description

blade wind turbine

technical field

The utility model relates to a wind power generator, which converts wind energy into electric energy, and is suitable for household electricity consumption in cities, villages and mountainous areas, or as a supplement for household electricity consumption.

Background technique

Wind is a natural phenomenon on Earth, which is caused by the radiant heat of the sun. The sun irradiates the earth's surface, and the various parts of the earth's surface are heated differently, resulting in temperature differences, causing atmospheric convection to prevail. Wind is flowing air with speed and density, so it contains energy. Wind is clean energy. In ancient times, wind energy was used as power to drive devices for rice milling, irrigation and drainage.

Experts estimate that the energy contained in the wind is much higher than what humans have been able to control so far. The energy obtained from burning coal all over the world every year is less than 1% of the energy that wind power provides us at the same time. It can be seen that wind energy is one of the most important energy sources on the earth. Reasonable use of wind energy will not only avoid burning fuel to produce exhaust pollution, but also alleviate the increasingly serious energy crisis.

Wind power is suitable for providing electric energy for some fixed places. Because it is not windy every day, the wind generator is suitable as a supplementary power source for households in cities and villages as well as in mountainous areas.

Contents of the invention

The purpose of the utility model is to provide a blade-type wind power generator which can generate electricity by using light wind.

The above-mentioned purpose of the utility model is achieved in this way, described as follows in conjunction with accompanying drawing.

A blade-type wind power generator, which is composed of a generator, blades and a cone, the cone includes an inner cone 7 and an outer cone 4 that are inverted sets of each other, the inner cone 7 and the outer cone 4 A plurality of spiral deflectors 6 arranged around the axis are connected between them, and a generator 12 is installed inside the inner cone 7; a hub 9 with blades 8 is installed on the generator shaft 11, and the blades 8 are placed in the inner cone 7 Out of the large end and inside the small end of the outer cone 4; the outer cone 4 is installed on the support rod 2 and can freely rotate around the support rod 2.

The said inner cone 7 which is an inverted suit is placed inside the outer cone 4, the small head of the inner cone 7 is in the same direction as the big head of the outer cone 4, and the big head of the inner cone 7 is in the same direction as the outer cone 4. In the same direction, an annular cone cavity is formed between the outer cone 4 and the inner cone 7.

The width L of the said blade 8 changes proportionally with the radius of rotation R of the blade, and the radius of rotation R of the blade increases, and the width L of the blade becomes wider accordingly.

The installation positions of said support rod 2 and the outer cone 4 are close to the big end of the outer cone 4 .

The beneficial effects of the utility model are: increasing the speed and density of the wind flowing through the blades, increasing the volume flow of the wind flowing through the blades, increasing the output electric power, and enlarging the utilization rate of wind energy.

Detailed ways

The utility model is further described below in conjunction with the embodiment shown in the accompanying drawings.

The working schematic diagram of the wind turbine is shown in Fig. 1 . The large cone opening at the left end of the outer cone 4 has a large area. When the wind entering the large cone flows in the right direction as shown in the diagram, the cross-sectional area of the outer cone 4 gradually becomes smaller, so that the wind with a smaller flow rate increases the flow rate in the cylinder 4 first. , increasing the density. Then arrive at the small end of the inner cone 7, the cross-sectional area of the inner cone 7 gradually increases from left to right, so that the annular cross-sectional area between the two cones is further gradually reduced, the flow velocity and the wind speed in the two cones The density is further improved, and at the same time, the spiral deflectors 6 in the two cones make the fast-flowing wind rotate around the axis again. Finally, the fast-flowing wind that rotates around the axis acts on the blades 8 and rotates the generator 12 through the hub 9 to output electric energy.

The outer cone can rotate freely around the support rod 2. The installation position of the support rod 2 is close to the left end of the outer cone 4. The wind force in the tube mainly acts on the blades 8, and the main resistance surface is at the right end of the outer cone 4. Therefore, the outer cone The large taper mouth of tube 4 left ends faces the wind direction all the time.

The projections of the blades 8 and the hub 9 along the axis of rotation are shown in FIG. 4 , and the distances between the projections of the blades are equal. Three views of the structure of the radially proportional blade 8 are shown in FIG. 5 , the width L of the blade 8 changes proportionally with the radius R of the blade's rotation. As the radius of rotation R of the blades increases, the width L of the blades becomes wider, so that the wind flowing through the cone and rotating around its axis can act on the blades 8 and then flow out of the cone, improving the utilization rate of wind energy.
