Description

Technical Field

[0001] The invention relates to a wind power machine, namely an all-weather vertical axis wind power machine. Background Art

[0002] Wind turbines can be driven by wind and can convert wind into various energies, especially electricity. Commonly used wind turbines are axial flow and radial flow. The shaft of the axial flow fan is placed horizontally, and the root of the fan blades is installed on the fan shaft. The rotating shaft of the radial flow is a vertical shaft, and the fan is installed on the outside of the vertical shaft. Axial flow wind turbines are currently widely used, while radial flow wind turbines are rarely used. The reason why radial flow wind turbines are rarely used is mainly that after the fan blades on both sides of the vertical shaft receive the same direction of wind, the torque generated is in opposite directions, which offset each other and cannot rotate. The "High Torque Vertical Shaft Deviation Wind Turbine (202122525734.X)" developed by me makes the fan blades on both sides of the vertical shaft into different convex and concave shapes, so that the torque on both sides forms a large deviation, thereby rotating the wind turbine. In addition, a wind shield, also known as a wind shield, is installed on one side to block the airflow. A wind-assisting plate that receives the airflow is installed on the other side, which increases the torque difference on both sides of the vertical shaft by several times, providing conditions for the popularization and application of vertical axis wind turbines. However, this type of wind turbine is not easy to rotate when the wind is weak or there is no wind. Its working performance is poor in many areas with low wind speed and cannot meet people's needs. Summary of the invention

[0003] The purpose of the present invention is to provide an all-weather vertical axis wind turbine which can rotate and work in strong wind, light wind or even no wind, and has a simple structure, low cost and is easy to popularize and apply.

[0005] The booster is a hair dryer, and the air outlet of the hair dryer is opposite to the outer end of the inner concave surface of the fan blade.

[0006] The hair dryer is installed on a hair dryer frame.

[0008] The hair dryer is provided with multiple layers, and each layer is provided with multiple parts.

[0009] The wind-assisting plate and the wind-shielding plate are supported by a bracket, and the bracket is connected to the rotating outer sleeve of the vertical shaft.

DETAILED DESCRIPTION

[0016] First embodiment: Figure 1 , Figure 2 An all-weather vertical axis wind turbine is introduced. The wind turbine 1 has a vertical axis 2, a rotatable shaft sleeve 3 is arranged outside the vertical axis, and blades 4 are arranged outside the shaft sleeve. Figure 3 , Figure 4 It can be seen that one side of the fan blade is an inner concave surface 7 and the other side is an outer convex surface 8. This fan blade is installed on the outer periphery of the shaft sleeve of the vertical shaft. When natural wind blows, the fan blade on one side of the vertical shaft is as shown in FIG. Figure 5 As shown in FIG. 1 , the airflow hits the inner concave surface 7 of the fan blade, and the airflow has nowhere to go, so it can only push the fan blade to rotate. Figure 6 As shown, the airflow hits the sharp corner of the outer convex surface and can slide along the surface, with very little thrust on the blades. In this way, a torque difference is generated on both sides of the vertical shaft, and the blades will rotate and work. Obviously, when the natural wind force is strong, there is no problem with the operation of this wind turbine. However, when the natural wind is weak or there is no wind, this wind turbine is difficult to work. In order to solve this problem, this example has made the following improvements: the periphery of the vertical shaft 2 is equipped with a booster that can push the blades 4 to rotate. When the natural wind force is sufficient, the wind turbine can rotate normally and work. When the natural wind force is insufficient or there is no natural wind, starting the booster can make the blades of the wind turbine continue to rotate around the vertical shaft. Obviously, there are many types of boosters with this function, and only one of them is listed below.

[0017] Depend on Figure 2 It can be seen that the booster is a hair dryer 5, and the air outlet of the hair dryer is opposite to the outer end of the inner concave surface 7 of the fan blade.

[0018] The hair dryer 5 is installed on a hair dryer rack 6, and the hair dryer rack is shaped like a column. Multiple layers of hair dryers 5 are installed on the column, and each layer of hair dryers is opposite to a layer of fan blades. The lower end of the column can be buried below the ground and fixed. The column can also be rigidly connected to the vertical shaft, which is equivalent to being buried underground. In addition, the column can also be made movable, and the positions of the hair dryer and the column can be adjusted accordingly as the wind direction changes. There are many ways to move the column, for example, a walking wheel is installed at the lower end of the column, which can be moved on the ground. Or the column is rotatably connected to the vertical shaft, and the relative position with the vertical shaft can be appropriately adjusted. Of course, the column does not need to rotate around the vertical shaft like the fan blade, and can only be adjusted with the change of wind direction, so as to maintain a relatively stable position. After installing this hair dryer, when the natural wind force is insufficient, the hair dryer can be turned on to blow air to the outer end of the concave surface of the fan blade to drive the fan blade to rotate.

[0019] A large number of experiments have shown that due to the long blades, the airflow of the hair dryer reaches the outer end of the blades directly, thus generating a large torque. Taking the wind turbine driving the generator as an example, although the hair dryer consumes a certain amount of electricity, the amount of electricity generated by the generator driven by the rotation of the blades far exceeds the amount of electricity consumed by the hair dryer. In this way, the wind turbine can still maintain stable operation under weak or no wind conditions.

[0020] To take a step back, even if the power consumption of the hair dryer is less than the power generation of the wind turbine driven by the hair dryer, this hair dryer will still play a role when the natural wind is insufficient but the power generation is not allowed to stop.

[0021] The second embodiment: Figure 7 As shown, multiple fan blades 4 are installed on the periphery of the vertical shaft 2, and multiple hair dryers 5 are installed on the periphery of the fan blades through multiple hair dryer racks 6. In combination with the previous embodiment, it can be seen that the hair dryer is installed in multiple layers, and each layer of hair dryers is opposite to the inner concave surface of a layer of fan blades. Each layer of the multi-layer hair dryers is equipped with multiple hair dryers. In this way, multiple hair dryers work together at different heights and different angles, so that the wind turbine can maintain all-weather operating performance and obtain huge economic benefits.

[0022] The third embodiment is improved on the basis of the above embodiment. Figure 8 , Fig. 9As shown, two upright panels are installed on the periphery of the vertical shaft 2. One of them is called a wind shield 10, also called a wind shelter, which is installed on the periphery of the fan blades on one side of the vertical shaft. The other is called a wind-assisting plate 9, which is installed on the periphery of the fan blades on the other side. There is a distance between the wind shield and the wind-assisting plate called an air outlet 11. The shapes of the wind shield and the wind-assisting plate are preferably arc-shaped plates bent around the axis of the vertical shaft. Generally speaking, the width of the wind shield preferably covers a 90° angle range of the outer circumference of the vertical shaft, the air outlet covers a range of 80-95° in turn, and the wind-assisting plate should cover the following 45-90° range. The arc-shaped plate recommended in the figure uses a translucent material, which is light in weight and high in strength. Of course, the material used for the arc-shaped plate can be other opaque materials.

[0023] During operation, the wind shield 10 and the air outlet 11 should be in a position opposite to the wind direction. The airflow relative to the wind shield slides along the outer surface of the wind shield and has no effect on the fan blades. The airflow relative to the air outlet 11 directly pushes the fan blades to do work. The remaining airflow after doing work should have flowed away along the tangential direction of the circle, but with the restriction of the wind-assisting plate 9, this part of the airflow cannot go away, but slides along the inner curved surface of the wind-assisting plate. Since the wind-assisting plate is very close to the outer end of the fan blade, the sliding airflow together with the dragged airflow continues to act on the outer end of the fan blade. Since the force arm at the outer end of the fan blade is the longest and the torque formed is the largest, this part of the wind force is also fully utilized.

[0024] As can be seen in the figure, the hair dryer 5 is installed on the wind-assisting plate 9. Of course, a column-type hair dryer rack 6 can be added inside or outside the wind-assisting plate, and the hair dryer is installed on the hair dryer rack. The hair dryer in the figure is installed on the inner side of the wind-assisting plate. Of course, it can also be installed on the outer side of the wind-assisting plate, and the air outlet passes through the wind-assisting plate and faces the inner concave surface of the fan blade. The hair dryer in the figure is only one part, and of course, the number and position of the hair dryers can be as described in the previous embodiment, with multiple parts and multiple layers.

[0025] Obviously, after the wind turbine is equipped with a wind-assisting plate and a wind-shielding plate, the utilization rate of natural wind is greatly improved. On this basis, the installation of a blower can greatly enhance its working performance.

[0026] The fourth embodiment is improved on the basis of the above embodiment. Fig.10 As shown, the blower is installed on the wind-assisting plate 9 and the wind shield 10. In the absence of wind, the wind shield has lost its function. After the blower is installed, it is equivalent to another wind-assisting plate. Installing multiple blowers on the periphery of the wind turbine will provide greater driving force on the fan blades, generate greater torque, and greatly improve the operating performance, thereby achieving all-weather efficient operating capabilities.

[0027] The fifth embodiment: Based on the above embodiment, the installation method of the wind shield 10 and the wind assisting plate 9 is improved. Fig.11 , Fig.12As shown, the wind shield and the wind assisting plate are both supported by a bracket 12, and the bracket is rotatably connected to the vertical shaft, so that the positions of the wind shield and the wind assisting plate can be adjusted. Since the bracket, the wind shield and the wind assisting plate are heavy and inconvenient to move, a ground wheel 13 is provided below, and the ground wheel cooperates with the track 14. Of course, there are many forms of the track, and the example shown in the figure is a raised steel rail. In fact, a relatively hard flat ground is also a track. There are many forms of cooperation between the ground wheel and the track. Here, it is recommended that the ground wheel and the track be magnetically suspended. Magnetic suspension technology is a prior art and is very suitable for large wind turbines with heavy brackets.

[0028] Since the bracket can rotate, it is particularly suitable for adjusting the position of the wind shield and the wind assisting plate. If there is no such structure, the installation position of the wind shield and the wind assisting plate can only be determined according to the wind direction law of the area where the wind turbine is located. With this rotating device, the installation position of the wind shield and the wind assisting plate can be controlled by mechanical or intelligent equipment.

[0029] Similarly, larger blades are also very heavy. Therefore, the figure introduces the support structure for the blades. As can be seen in the figure, the outer ends of the blades are provided with rollers 15, which are supported by an annular slide 16, and the slide is supported on the base ground through a fixed frame 17. Magnetic suspension is used between the roller and the slide. In this way, although the blades have multiple layers and branches and are very heavy, they can rotate very flexibly, and the working efficiency of the hair dryer is greatly increased.

[0030] Furthermore, as in the aforementioned embodiment, the wind shield and wind assist plate in the above structure are equipped with a blower to supplement the thrust of the fan blades when the natural wind force is insufficient.

[0031] The sixth embodiment: Based on the above embodiments, a new booster is introduced. Fig.13 As shown, the booster is a tractor 18 that can pull the fan blades to rotate. The tractor can move along a circular route under the fan blades, pulling the fan blades to rotate around the vertical axis. It is best to use a new energy vehicle as the tractor. In this way, when there is insufficient natural wind, the wind turbine can be maintained in operation without a hair dryer. Experiments have shown that this method has higher operating efficiency.
