Technical Field

The invention relates to a wind energy utilization device, in particular to an adaptive rotor vertical axis wind power generation device and a control method.

Background technique

New energy technologies mainly include the technology research and development, equipment manufacturing, project construction and operation management of renewable energy such as solar energy, wind energy, biomass energy, hydropower, geothermal energy, etc., and their characteristics are as follows: the market scale is constantly expanding: as the global demand for renewable energy continues to increase, the scale of the new energy technology market is constantly expanding; technological innovations are constantly emerging: the new energy technology market is a highly innovative field, with new technologies and products constantly emerging; the industrial chain is constantly improving: as the market continues to develop, the industrial chain is constantly improving, and the collaboration and cooperation between various links are also closer. Wind power has the advantages of being renewable, clean energy, low cost, and distributed.

In terms of wind energy utilization, horizontal axis wind turbines are still the most widely used. Horizontal axis wind turbines have their advantages, such as the fact that horizontal axis wind turbines have been fully industrialized and have comprehensive supporting production and operation experience. However, vertical axis wind turbines have the characteristics of small structure volume, no directional requirements, easy maintenance, safety, high efficiency, low noise, low cost, and easy maintenance. However, most of the current vertical axis generators have a blade structure with a fixed windward angle. This structure has a large reversal torque, that is, a large negative torque, resulting in a small effective torque, which reduces the overall efficiency, and the starting wind speed is high, and the production cost is also high. There are also the following deficiencies: Insufficient utilization of wind energy resources: Insufficient utilization of wind energy resources, mostly using winds above level 4, and abandoning winds below level 3, which cannot maximize the potential of wind power generation; Low power generation efficiency: The uneven distribution of wind speed will cause large fluctuations in the output of wind turbines, thus affecting the power generation efficiency of the entire wind farm; Inconvenient equipment installation: Wind power equipment is generally large, and transportation and installation are also troublesome; Long investment payback period: The investment payback period of wind power projects is extended, reducing the economic benefits of the projects and other deficiencies.

Although there are rectangular vertical axis generators at present, they do not have adaptive performance and have poor adjustability in light winds. In particular, the starting conditions are unstable, the starting torque is large, and the practicality is weak.

Detailed ways

The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

The purpose of the present invention is to provide a wind turbine generator and control method with low starting wind speed, high efficiency, simple structure and low cost, so the technical solutions involved in the prior art are improved and enhanced. For example, in the existing horizontal axis and vertical axis wind turbine generators, the angle of the blades is fixed, but as the blades rotate, they will be subjected to negative torque when against the wind. In order to avoid this situation, an improved and optimized technical solution is adopted in this embodiment.

Embodiment 1:

The adaptive rotor vertical axis wind power generation device of this embodiment, as shown in Figure 1-12, has a basic structure that includes at least the following parts: a power shaft 1, a generator 2, blades 3, a blade shaft 4, a bearing frame 5, a base plate 6, a static limit structure 7, a dynamic limit structure 8, a balance adjustment device 16, blades A31, and blades C32. The relationship between them and the working principle are explained below in conjunction with the embodiments.

The power shaft 1 of the device is connected to the generator 2, which can directly output torque to drive the generator 2 to rotate and generate electricity. The power shaft 1 is connected to a base plate 6, on which a bearing frame 5 is arranged. The bearing frame 5 contains bearings and is rotatably connected to the blade shaft 4. There are blades 3 on the two axes of the blade shaft 4. The blades 3 here refer to all four blades (single blades A31 and blade C32). The blade shaft 3 is horizontally arranged with the axis of the power shaft 1 as the center. It can rotate under the action of wind and output power to the power shaft 1 to generate electricity or do work.

Blades 3 are fixedly arranged at both ends of the blade shaft 4. The planes of the blades 3 at both ends are not in the same plane. The angle between the blades 3 at both ends is a set angle. The angle between the two blades 3 is between 60-120 degrees, preferably 80-90 degrees, and most preferably 85 degrees. This is when one blade 3 is in a vertical state, the blade 3 at the other end of the blade shaft 4 has an angle of 5 degrees with the horizontal plane, and is tilted below the horizontal plane in the windward direction. In this way, there is an inclination angle, which makes it easier for the blade 3 to automatically flip, and the working state conversion is more timely. Because the blade shaft 4 is supported by the bearing frame 5, the blade shaft 4 can rotate under the action of wind;

When the blade is used by wind, the force on the blade 3 is related to the area. Therefore, the center of the blade 3 is offset from the axis of the blade shaft 4, as shown in Figure 12. Taking blade A31 as an example, the same blade A31 is divided into two areas A1 and A2. The boundary of the area is based on the installation position of the blade shaft 4. The area A1 on the side with a smaller area of the blade A31 is area one, which is set above the horizontal plane of the blade shaft 4; the area A2 on the side with a larger area of the blade is area two, which is set below the horizontal plane of the blade shaft 4. In this way, under normal circumstances, due to the larger area and weight of the two areas, in the absence of other forces, it will automatically move downward. In this embodiment, the blades A31 and C32 at both ends of the same blade shaft 4 are installed and fixed at a certain angle. Then, under the action of gravity, due to the weight of the two areas corresponding to the blades A31 and C32, they will naturally droop below the blade shaft 4, as shown in state 1 in Figure 3, and also shown in Figure 1.

That is, the two areas on the larger area side of the blade 3 at both ends of the same blade shaft 4 are arranged below the horizontal plane of the blade shaft 4 and at 45 degrees to the horizontal plane.

In order to make the working state of the blade more stable, the ratio of the outer side lengths of the two regions one and two of the same blade 3 is 0.618 golden ratio, that is, the outer side length of the first region: the outer side length of the second region = 0.618.

In this way, the weight of the blade 3 relative to the blade shaft 4 is asymmetric, which is not conducive to dynamic balance and free flipping of the blade 3. In order to better flip freely and form dynamic balance, a weight is configured for a zone on the side with a smaller area of the blade 3, and a counterweight 16 is added, as shown in Figure 12, to balance the weight difference caused by unequal areas. However, the first zone and the second zone are not completely equal, but are adjusted so that the weight of the second zone on the side with a larger area of the blade 3 is slightly larger than the first zone on the side with a smaller area of the blade 3. In this way, the blade 3 can droop naturally when there is no wind, and can also be started to rotate at any time in a breeze, thereby meeting the requirements of adaptive wind speed and having higher working efficiency.

When the blade 3 with eccentricity rotates around the axis of the blade shaft 4, it cannot rotate arbitrarily. At least one of the blade 3 and the blade shaft 4 has a limit structure, which is a dynamic limit structure 8; the corresponding static limit structure 7 is assembled on the base plate 9, or on other structures connected to the base plate 9. In this embodiment, the dynamic limit structure 8 is set on the blade shaft 4, as shown in Figure 10, and the angle range of the blade rotation is limited to 90 degrees, and different states are changed with the different rotation angles of the power shaft 4. As shown in Figure 3, the rotation range of the blade A31 in the figure is within the 90-degree range between the vertical direction and the horizontal direction.

The limiting structure here can be composed of at least one of a limiting block, a limiting strip, and a limiting plate, and can be arranged on components such as blades, blade shafts, bearings, bearing frames, and power shafts. As long as the dynamic limiting structure is set on the rotating blade shaft 4 or blade 3, and the static limiting structure is set on a relatively static base plate 9, bearing frame 5 and other relatively static structures.

Based on the above structure, its working principle and process are further explained:

In order to better illustrate the working process, this embodiment is divided into five working states: a silent zero working state, and the first, second, third, and fourth working states. The conversion from zero to the first, second, third, and fourth states is completed, that is, the power shaft 1 rotates one circle under the action of wind, and the process is repeated thereafter.

Silent working state: refers to the state of the entire device and the initial working position of each blade 3 when there is no wind. As shown in Figures 1 and 2, the blades 3 are in a free-hanging state, because two blades 3 are connected and fixed on the same blade shaft 4, which is 45 degrees to the horizontal plane, as shown in Figure 3 State 1 is clearly shown, and Figure 4 is the observation view of the observer facing away from the wind. The device is not started and is in a waiting state.

The first working state: as shown in Figures 5 and 6, Figure 5 is a top view, and the wind direction is from the south, indicated by a hollow arrow, and the same applies to the following. When the wind comes, the blade A31 is affected by the wind on the blade surface. Since the area of the second zone of the blade A31 is larger than the area of the first zone, and the blade shaft 4 can rotate freely, from the end of the blade A31 (as shown in the viewing direction of the gray arrow in Figure 5), the blade A31 rotates counterclockwise about 45 degrees until it reaches the limiting effect of the limit device and stops at a vertical position, as shown in state 2 in Figure 3. At this time, the blade A31 is subjected to the greatest force of the wind, and the blade C32 at the other end of the same blade shaft 4 is at a 90-degree angle with the blade A31, so at this time, the blade C32 is in a horizontal state, and the force of the wind is the smallest, that is, the resistance is the smallest; the other group of blades 3 presents the working state of blade A31 state 3 in Figure 3, forming a torque to propel the power shaft 1 to rotate. And it remains in this position under the restriction of the limit structure.

The second working state: as shown in FIG7 , under the action of wind, blade A31 rotates blade shaft 4 horizontally about 90 degrees. Since the effect of wind gradually decreases at this time, blade A31 and blade C32 are in a free 45-degree angle state, as shown in state 3 of blade A31 in FIG3 . Basically, there is no effect on blade A31 and blade C32 on the windward side. At this time, wind force acts on another group of blades 3, and power shaft 1 continues to rotate under the action of another group of blades 3 and inertia.

The third working state: as shown in FIG8 , blade A31 and blade C32 continue to rotate driven by the blade shaft 4 and under the action of inertia, and the blade shaft 4 rotates about 90 degrees. As the effect of wind gradually increases at this time, blade A31 rotates into a horizontal state under the action of wind, while blade C32 is in a vertical state, which is affected by the greatest wind force and drives the blade shaft 4 to rotate, as shown in state 4 of blade A31 in FIG3 ; at this time, the other group of blades 3 are in a free state.

The fourth working state: as shown in FIG. 9 , blades A31 and blades C32 continue to rotate driven by wind and under the action of inertia, and the blade shaft 4 rotates about 90 degrees. Since the effect of the wind gradually weakens at this time, blades A31 and blades C32 are in a free state. At this time, the wind acts on another group of blades 3. The wind force acts on the other group of blades 3 at the maximum at this time, and drives the blade shaft 4 to rotate, and drives blades A31 and blade C32 to rotate, as shown in blade A31 state 4 in FIG. 3 .

The above four states are repeated to form continuous rotation torque and power output.

In this embodiment, a blade group is formed by two blade shafts 4 and blades 3 at both ends. This structure is easy to generate continuous and relatively stable force within a complete circle. There are at least two or more blade groups, and it can also be one or more blade groups.

Embodiment 2:

The main part of this embodiment is the same as the previous embodiment, and it also has a control unit for the rotation control and start-stop management of the device. The device is mainly a controller unit, including a controller substrate 9, a spring 10, a steel plate 11, a weather vane 12, an adjustment inner cylinder 13, an adjustment outer cylinder 14, and a terminal post 15.

A spring sheet 10, a steel sheet 11, and a weather vane 12 connected to the spring sheet 10 are provided on the controller substrate 9. The steel sheet 11 is a rigid structure and has a contact. The spring sheet 10 is an elastic structure. When the weather vane 12 connected to the spring sheet 10 is tilted by wind, the spring sheet 10 can be linked to deform toward the steel sheet until the contact on the spring sheet 10 and the contact on the steel sheet 11 contact each other and become conductive. A contact 15 is connected to the two contacts, and other control circuits can be connected to the contact 15, so that the contact can be put into working state or the generator can be braked to stop running.

At the position where the spring piece 10 and the base plate 9 are installed, an adjusting inner cylinder 13 and an adjusting outer cylinder 14 are also provided. The adjusting inner cylinder 14 can be moved up and down in the adjusting outer cylinder for adjustment, so as to adjust and change the height of the deformable part of the spring piece 10. The higher the adjusting inner cylinder 14 is, the shorter the deformable part of the spring piece 10 is, and the greater the wind force required for the contact point of the spring piece 10 to contact the contact point on the steel plate 11 is. Therefore, by changing the height of the adjusting inner cylinder 13, the control unit can be used to start and stop the power generation device of the invention or prevent the power generation device from stopping when the wind speed is too high.

That is, this is a speed control switch, which is composed of a spring sheet 10 and a steel sheet 11. The spring sheet can be deformed under the action of wind and contact with the steel to be turned on. The deformation degree of the spring sheet can be changed by adjusting the height of the inner cylinder 13.

The speed control switch stops rotating by connecting the contacts of the spring (10) and the steel plate (11) to the huge torque formed by the power output of the power generating device, that is, by short-circuiting the power output line of the generator, the operation is forced to stop, thereby protecting the safety of the entire device and personnel.

The above-mentioned embodiment is not only a wind turbine or an ocean tidal power machine, but also a wind or water power device, which can be a wind power water pump, a wind power air pump, a wind power mill, and various power devices such as various fluid, wave energy, and tidal energy devices.

The present invention has been verified through multiple practices, as shown in FIG13 .

The effects and features of the present invention are as follows: the device has a low starting wind speed and can be started at a level 1 wind speed of 0.8 m/s, which is the known minimum wind speed requirement; it can start generating electricity at 1.6 m/s, and can generate electricity normally at level 2 wind; the reverse torque of the adaptive rotor vertical axis generator is close to zero; based on the innovative design of the adaptive rotor, the reverse rotation torque of the wind blade on the windward side is very small, and the self-spin torque of the wing is also close to zero, so that the forward rotation torque achieves a higher efficiency; the manufacturing process is simple, easy to carry, and easy to install.

Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
