At present, most of the current horizontal-axis wind power generation devices in the world use three large blades directly driven by natural wind. The disadvantages include:

1. In order to meet the power generation requirements, the blade must have a sufficiently large diameter, so that the diameter of the blade of the existing power generation device is large, which is not only high in manufacturing cost but also difficult to maintain and maintain.

2. Due to the large diameter of the blade, of course, the moment of inertia is also large, so starting is difficult, and power generation cannot be started in a small wind force (less than 3 winds);

3. Due to the large inertia of the blade, the rotation speed of the blade is low, so the speed increase device needs to be added in the generator set, resulting in high cost;

4. There are few blades, and the wind utilization rate and power generation per unit area are low;

5. In order to obtain high airflow, it is necessary to erect a tower body several tens of meters high, which is not only expensive to manufacture, but also the airflow below the blade is not utilized.

The present invention is directed to the above-mentioned shortcomings of the existing wind power generators, and improves the power generation efficiency while reducing the manufacturing cost, thereby reducing the "I electricity cost." Summary of the invention

2. The unit impeller area generates a large amount of electricity. Due to the use of trapping air ducts, after the natural wind passes through the air duct, the wind energy gathers and strengthens several times as much as the natural wind; therefore, the power generation per unit impeller area will also increase several times, and at the same time, due to the vertical combination of several wind power generation modules, Most of the wind power generation modules are located higher than the ground, and the air velocity is larger than the ground, which can greatly increase the power generation of a single unit.

Referring to Figures 1, 2 and 3, there is shown a wind power plant of the present invention comprising a base 10 and a matrix wind power generator 20 erected (vertically) on the base 10, wherein :

The seat body 10 includes an annular track 11 fixed to the ground and a base 12 that is rotationally moved on the circular track 11. The base 12 is further provided with a wind direction monitoring device (using the prior art) and a tracking slewing device, and the wind direction monitoring device and the tracking slewing device are electrically Connecting, capable of measuring wind direction and feeding to the tracking slewing device, the tracking slewing device receiving information provided by the wind direction monitoring device, and then controlling the rotation or positioning of the seat body 10 on the track to ensure the seat body 10 The windward side of a plurality of wind power generation modules is adapted to the wind direction. In this embodiment, the annular track 11 has two loops (one outer ring and one inner ring, and of course, a plurality of rings), and the base 12 is rectangular; The tracking slewing device includes a plurality of rollers 13 disposed at positions corresponding to the outer ring 内 and the inner ring 该 of the base 12, and the base 12 is circumscribed by the driving or braking of the plurality of rollers 13 Rotational movement or positioning on the track 11;

The matrix wind power generation device 20 has a plurality of wind power generation modules 21, and each of the wind power generation modules 21 has a windward surface 211 on one side, and all of the wind power modules 21 are arranged in a matrix. The windward faces 211 of the power generation module 21 are all facing the same side, and any two adjacent wind power generation modules 21 are fixed together by mechanical coupling structures (such as bolting, welding or tie rod coupling), and the lowest row of wind power generation The module 21 is fixedly connected to the base 12 of the base 10;

Referring to Figures 7 and 8, there is shown a preferred embodiment of the wind power generation module 21 provided by the present invention. As can be seen from the figure, each wind power generation module 21 has a rectangular parallelepiped structural frame 212, and the structural frame 212 is filled with a gas impermeable material, so that a longitudinal direction of the wind power generation module 21 is formed in the structural frame 212. The wind trapping duct 213 has an inner shape line (inner wheel gallery) of the wind trapping duct 213 as a contraction curve, and a front end thereof (ie, an end corresponding to the windward side surface 211) is an air inlet 214 having a larger area, and The end is a smaller air outlet 215. A horizontal axis impeller 216 is disposed on the air outlet 215 of the wind trapping duct 213. The rear end of the shaft of the horizontal shaft impeller 216 is directly connected to a generator 217. When the wind is blown from the air inlet 214 of the wind trapping duct 213, it is blocked by the airtight material in the structural frame 212, and the air line 215 is formed along the contraction curve of the wind collecting duct 213. Concentrated.

It should be emphasized that the inner shape line of the wind trapping duct 213 of the present invention is designed according to the principle of wind tunnel. Wind tunnels are often used to test the performance of a scaled-down aerospace vehicle model in aerospace applications at a certain rate of airflow. As shown in Figures 9 and 10, the device produces airflow through the shrinking air duct in a closed closed loop. The shape line is accelerated, and the acceleration is formed in the small interface pipe. A higher speed airflow allows the aircraft model to simulate high speed flight. The speed VI is formed by a fan inside the pipe. The tail wind generated by the small interface A2 is accelerated by the fan. The air source generated by the A1 cross section is changed from the airflow generated by the fan to the natural wind, and the natural wind flows through the contraction air duct at the speed of VI. V2 acceleration occurs when the inner line is to the small interface A2. The inner line of this shrinking air cylinder is strictly calculated, and the result must be: A1/A2=V2/V1, resulting in V2=Vl x Al/A2. For example, the area of the air inlet 214 is four times the area of the air outlet 215. The level 2 light wind of 1.6-3.3 m/s can be improved to a level 5 wind, which is sufficient to drive the horizontal shaft impeller 216 provided by the air outlet 215. Rotating power generation. Therefore, the inner shape line of the wind trapping duct 213 of the present invention is a contraction curve, and is different from the size of the mouth of the general bell mouth, and the bell mouth is not subjected to the above-mentioned strict proportional acceleration phenomenon. By using this principle, the weak wind that cannot drive the impeller in nature is improved by a high multiple, and the wind energy capable of efficiently pushing the impeller is obtained, and the contracted inner line of the wind trapping air passage is accelerated by the curved surface of the inner shape line, so The shape is a long and deep curved cylinder.

The working process of the wind power generation device of the present invention is as follows:

1. In each of the wind power generation modules 21, natural wind enters through the air inlet 214 of the wind trapping duct 213, and due to the polymerization strengthening effect of the air passage, after flowing through the air passage, the impeller is several times strengthened, and then pushed The impeller rotates to generate electricity.

2. Each wind power generation module 21 is combined horizontally and vertically by mechanical coupling to form a rectangular array.

3. The entire rectangular array is placed on a swivel device consisting of a base 12 and an endless track 11, and the front facing wind angle of the array is automatically adjusted by the wind direction.

With the above structure, the following advantages are obtained:

1. Since the wind power generation modules 21 are arranged from low to high, while using high-altitude wind power generation, wind power close to the ground position is also utilized, and the wind power utilization rate is improved;

2. The slewing device consisting of the base 12 and the circular track 11 can adjust the windward direction of the entire power generating device for the wind direction, and can utilize the wind to the maximum extent, and can generate electricity regardless of the wind direction, thereby avoiding the device being idle;

3. Through the polymerization strengthening of the wind trapping air duct, even under the climatic conditions of the second-class light wind, the power generation can be realized, and the adaptability of the power generating device is improved; 4. The wind force is strengthened by the polymerization strengthening effect of the wind trapping air passage, so that the diameter of the impeller can be designed to be smaller, and the generator 217 can be directly driven to generate electricity without a shifting device, thereby lowering the cost and reducing the power generation cost.

In the above embodiment, each wind power generation module 21 is about 10 meters high. In the case where only 3 X 3 wind power generation modules 21 are installed as shown in FIG. 1, the overall height of the matrix wind power generation module 21 is about 30 meters. M, can rely on the strength of the base 12 to resist wind shaking.

In the following embodiments, as shown in FIG. 4, FIG. 5, and FIG. 6, 10 x 10 wind power generation modules 21 are installed, and the overall height of the matrix wind power generation module 21 reaches about 100 meters (or higher), and the weight is also It is greatly increased, so it is necessary to strengthen the overall structural strength and seismic resistance as follows: The annular track 11 provided on the ground has more than four rings, and the base 12 is still rectangular; and correspondingly on the base 12 The position of the ring is provided with a plurality of rollers 13 for driving or braking the plurality of rollers 13 to realize the rotational movement or positioning of the base 12 on the circular track 11; not only, but also fixed on the base 12 A balance weir 14 is slidably disposed on one of the loops (generally the one having the largest diameter) and then disposed between the two sides of the matrix wind power generator 20 and the balance weir 14 The plurality of pull anchor fixing structures 15 can rely on the stable torque provided by the balance cymbal 14 when encountering a large wind sway, so that the matrix wind power generation device 20 does not tilt. .

As is well known, in a plurality of wind power generation modules 21 of the matrix type wind power generation device 20, the pressure applied to the ground closer to the ground is increased, and the pressure is applied to the upper side, so that the wind power generation module 21 in the lower layer should be selected. A stronger material (for example, steel or alloy material) is used, and the upper wind power module 21 is made of a less strong material (for example, industrial plastic or resin material), thus saving At the same time as the metal material, the load-bearing capacity of the lower-layer wind power generation module 21 can be alleviated.

The above description is intended to be illustrative, and not restrictive, and many modifications, variations or equivalents may be made without departing from the spirit and scope of the appended claims. It will fall within the scope of protection of the present invention.
