Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and relates to a wind wheel device, and in particular to an omnidirectionally adjustable wind wheel device for wind power generation. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. Now, people are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly and has huge wind energy reserves, so it is increasingly valued by people.

[0003] Existing wind turbines can be divided into horizontal and vertical axes according to the direction of the blade axis, and can be used in horizontal or vertical directions. Most of them are suitable for wind fields within 20m / s or hurricanes. There is no blade system suitable for all directions of 360°.

[0004] The blade system of a common wind turbine cannot be started when the wind speed is lower than 1m / s, and must be cut out and stopped when the wind speed is higher than 20m / s. The classical dynamics theory of wind turbines is often used. The blade design refers to the lift model of the aircraft wing, the flow around the wind turbine airfoil theory and the aeroelastic coupling of the wind turbine system. The wind energy utilization coefficient is low, the efficiency is low, the volume is large, the space is occupied, the weight is heavy, the cost is high, and the transportation is inconvenient. Vertical axis wind turbines can be divided into lift type (Darrieu type) and drag type (Savonis type). Summary of the invention

[0005] The purpose of the present invention is to provide an omnidirectional adjustable wind wheel device for wind power generation, which can generate vortex vortex 90° directional wind rectification, can be applied to wind wheel devices in 360° omnidirectional wind fields, suitable for wind speeds of 1m / s to 72m / s, and suitable for advection and turbulent wind states.

[0051] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0052] Example

[0053] like Figures 1 to 4 As shown, an embodiment of the technical solution of the present invention is provided. This embodiment is a wind wheel device, which can be used in 360 degrees in the direction of the machine shaft, and the air inlet and outlet can be adjusted. It is suitable for wind turbines in small weak wind fields and hurricane fields, including a machine shaft 10, a wheel frame 20, four arc plates 30, four wind plates 40, an adjusting wheel disc 50, four secondary wind blades 60, a wind booster 70 and a gravity balancer 80.

[0054] The machine shaft 10 is used to support the entire wind rotor device and is the rotating shaft of the wind rotor device. The machine shaft is externally connected to the wind turbine generator set to output the wind power to the generator set.

[0055] The wheel frame 20 is connected to the machine shaft and rotates synchronously with the machine shaft. The wheel frame mainly supports and fixes four wind plates 40, four fixed blades 30 and four secondary wind blades 60. The overall structure of the wheel frame is a columnar frame. The wheel frame 20 includes an upper ring 21, a lower ring 22, four connecting bars 23 and eight spokes 24. The upper ring and the lower ring are connected by four connecting bars 23. The four connecting bars 23 are evenly and symmetrically distributed around the circumference. The upper ring 21 is connected to the machine shaft 10 through four spokes 24. The lower ring 22 is also connected to the machine shaft 10 through four spokes 24.

[0056] In another embodiment, the number of connecting bars and spokes of the wheel frame can be increased or decreased, such as three, five or six connecting bars, and the corresponding number of spokes of the upper ring or lower ring connected to the shaft can also be three, five or six. The number of connecting bars can affect the number of arc plates that can be installed, and the number of spokes can affect the number of wind plates and secondary wind blades that can be installed. It is best that the number of spokes of the upper ring and the lower ring is the same and equal to the number of connecting bars.

[0057] In this embodiment, the connecting bar 23 is arranged parallel to the machine shaft 10 . In another embodiment, the connecting bar 23 may be inclined with respect to the machine shaft 10 .

[0058] The side of each arc plate 30 is fixedly mounted on a connecting strip 23, and the arc plate is bent toward one side of the machine shaft to form an arc 301, and the axial direction of the arc is parallel to the machine shaft 10. The other side of the arc plate contacts or is close to the side of the wind plate adjacent to it. The arc plate is made of a plastic material with a certain elasticity and hardness, so that when the wind plate is adjusted, the wind plate will press the arc plate to further bend and deform, and the arc plate is in close contact with the wind plate, so that the resistance windward surface formed by the arc plate and the wind plate is complete. The resistance windward surface of the arc plate adopts an arc-shaped geometric surface structure to minimize wind damping.

[0059] Each wind plate 40 is rectangular, and has a first shaft portion 401 and a second shaft portion 402 at its two side edges respectively. The first shaft portion and the second shaft portion are integrally formed with the wind plate, or can be assembled and installed. In order to strengthen the structure of the wind plate, streamlined reinforcing ribs 403 or rib grooves are provided on the wind plate 40.

[0060] The two ends of the first shaft 401 are movably connected to the corresponding spokes 23 of the upper ring 21 and the lower ring 22, respectively, and the two ends of the second shaft are connected to the two adjustment wheels 50. The first shaft 401 of the wind plate serves as the axis of rotation of the wind plate 40, and the second shaft is used to connect with the adjustment shaft disk 50 to drive the wind plate 40 to rotate a certain angle to change the cut-out air volume. The number of wind plates is the same as that of the curved plates. A wind plate is provided behind each curved plate 30, and the air volume is changed through the curved plate 30 and the wind plate 40.

[0061] In this embodiment, there are two adjusting wheels 50, which are respectively located on both sides of the wheel frame 20; the adjusting wheel includes a wheel 51 and four linkage rods 52, the wheel 51 is connected to the machine shaft 10 for rotation, and each linkage rod 52 is connected to the second shaft portion 401 of a wind plate 40 and the wheel 51. In order to maintain the rotation consistency of all wind plates, all wind plates are connected to the wheel through linkage rods, and when the wheel is rotated, all wind plates are driven to rotate synchronously.

[0062] The root 601 of each secondary fan blade 60 is connected to the shaft 10, and the blade shell 602 of the secondary fan blade 60 is limited on the spoke 24 of the upper ring 21. Specifically, one end of the first shaft portion of the wind plate passes through a through hole set on the blade shell and is movably connected to the spoke. The secondary fan blade is a lift damping blade installed at the normal outlet of the wheel frame. The wind force passes through the arc plate and the wind plate inside the wheel frame, and the wind force spins and accelerates multiple times, which can drive the secondary blade to work again and be utilized.

[0063] The gravity balancer 80 is installed on the shaft and is located inside the wheel frame. The gravity balancer includes a sleeve 81 and four pendulums 82 evenly distributed on the circumference. The sleeve is installed on the shaft. The pendulum includes a rod 821 and a ball 822. One end of the rod is connected to the ball, and the other end is movably hinged on the sleeve. When gusts occur, the wind wheel device rotates too fast and the gravity balancer will play a balancing role to eliminate the impact of the gusts. In another embodiment, the number of pendulums can be two, three, five or six, etc.

[0064] The wind booster 70 includes an upper bracket 71, a lower bracket 72 and four capacity-enhancing blades 73; the upper bracket is connected to the machine shaft and is located on the outside of the wheel frame, the lower bracket is connected to the machine shaft and is located on the outside of the wheel frame, the upper bracket is provided with four branch arms 711 and a pull wire 712, the pull wire mainly serves to reinforce the upper bracket, similarly, the lower bracket has the same structure as the upper bracket, each capacity-enhancing blade is connected and fixed between the corresponding branch arms on the upper bracket and the lower bracket, and the angle of the capacity-enhancing blade and its position with the wheel frame can be adjusted to achieve the best wind gathering effect.

[0065] There is a bearing between the wind booster and the shaft. It does not rotate with the wheel frame and is stationary relative to the environment. It changes its position with the wind direction. The wind booster is a streamlined guide plate wind booster that increases the wind volume. Two booster blades are installed on the wind inlet direction to gather wind on the windward side and increase the area of ​​recovered air volume. The wind booster can automatically rotate according to the wind direction to select the collection direction. The booster blades are made of elastic structure, which can automatically adjust the windward angle according to the size of the wind force and will not be damaged by the wind.

[0066] Figure 5 , which is a view of another structure of a wind booster 70, including a bracket and a wind expansion blade 74, a balance blade 75, a tail blade 76 and a wind resistance shielding blade 77 fixed on the bracket;

[0067] The bracket is movably and rotatably connected to the machine shaft, the wind resistance shielding blades are arranged on the periphery of the wheel frame facing the wind, the wind expansion blades and the balancing blades are arranged on both sides of the wind resistance shielding blades, and the tail blades are arranged on the leeward side of the wheel frame.

[0068] This structure of the wind booster is simpler and more practical. It can also block the wind-blocking reverse side, increase the wind kinetic energy and eliminate negative energy. It can increase the wind volume introduced into the wind wheel device through the expansion blades. It can automatically adjust the balance blades and the wind direction balance tail wing so that the windward side receives the maximum wind volume. As for the strong wind protection of the wind booster, it also uses the overpressure self-rotating blade angle to eliminate the influence of overpressure wind.

[0069] like Figure 6As shown, each blade is also provided with an outer rotating piece 41, which is connected to the outer side of the wind plate 40 in a direction parallel to the machine shaft, and one side 410 of the outer rotating piece 41 is connected to the side of the wind plate close to the wind inlet direction, and the other side is a movable end 411, which can swing with the wind. Specifically, one side of the outer rotating piece can be connected to the wind plate by a shaft, so that the outer rotating piece can swing around the shaft.

[0070] When the wind wheel rotates, the outer rotating blade rotates, and its active end opens outward due to the action of centrifugal force. The greater the wind force and the faster the rotation speed, the greater the centrifugal force, and the degree of opening of the active end also increases. The opening of the active end shrinks the air volume inlet and reduces the air intake. At the same time, since the outer side of the outer rotating blade will be affected by the thrust of the wind, the thrust of the wind and the centrifugal force generated by the rotation are opposite forces, which act together on the outer rotating blade. The air intake at the entrance can be dynamically adjusted through the outer rotating blade.

[0071] In order to achieve good results, the design features of the curved plate and the wind plate of this embodiment are as follows:

[0072] (1) Minimize the windward area damping as much as possible, adopt a streamlined shape, and design the wind direction distribution;

[0073] (2) Increase the thrust surface as much as possible to obtain maximum kinetic energy.

[0074] The wind inlet is designed as a circular tangent, and the wind on the inclined wind direction inlet is rectified, encrypted, and accelerated to produce good thrust. The circular tangent inlet is a tangential arc. The windward inlet surface is an inclined plane. In order to enhance the plane resistance, ribs or rib grooves for downwind inlet are added. In order to increase the strong cut-out, a rotating shaft, i.e. the first shaft, is added to the tail of the wind plate. The flat part of the wind plate is cut apart from the curved part, which facilitates the intelligent cut-out of wind power and realizes wind power adjustment.

[0075] The curved surface of the wind plate is fixed on the wheel, and the blades cannot be adjusted. The flat surface can be moved with a pressure port at the head, and the streamlined body is reinforced with ribs or rib grooves, and the inlet head is streamlined. The tail of the flat surface of the wind plate can be provided with a swing angle tail. It is used to control the wind direction and can be made dynamic or fixed. The size of the bottleneck of the air inlet can be set with an intelligent adjustment port to meet the needs of different wind levels and wind forces, and various states of wind to achieve the best effect.

[0076] In addition, Figure 4As shown in the figure, the windward surface formed by the first curved plate 30a and the first wind plate 40a, the positive pressure wind energy enters from the circular tangent direction, is rectified, encrypted, and accelerated through the air inlet, increases the effective impact force and resistance pressure, obtains more kinetic energy, and is directed to the passive second curved plate 30b after being subjected to linear pressure through the plane of a wind plate 40a to form a secondary positive pressure impact force, and then is directed to the third curved plate 30c after being vertically subjected to pressure and pushed by the second wind plate 40b. After the third wind plate 40c is subjected to vertical pressure and driving force, it is successively introduced into the fourth curved plate 30d. The inclined plane of the fourth wind plate 40d simultaneously introduces the external positive wind pressure into the first curved plate 30a, once again enhancing the vertical impact thrust of the first wind plate 10d. After repeated iterations, a certain wind pressure value and air volume are reached in the wheel, and an internal vortex is formed. Then the airflow is spun out from the top or bottom.

[0077] When the wind is weak, the wind blades close to increase the wind kinetic energy. When the wind is too strong, the blades are opened to cut out. According to the wind strength, the wind cut-out amount is intelligently determined to ensure the rated power generation. When encountering a hurricane with a cut-out amount of 10-15 times the wind speed, the power generation will not be affected at all.

[0078] The wind wheel device of this embodiment uses any orientation and angle of 360° space to maximize the captured wind energy, far surpassing the horizontal and vertical axis unidirectional wind energy usage mode, so that weak wind can also be used to generate more electricity.

[0079] It can be applied to small micro wind turbines ranging from 1kw to 10kw, making them affordable for every household in rural areas. It has greatly changed the structure of clean energy. It does not require a specific wind field or a specific time, and can be installed almost everywhere regardless of day or night or climate.

[0080] The small machine has low noise, high power and good adjustability. Small distribution and large regionalization make the power grid more balanced, easy to adjust, fast adjustment speed, and do not require special installation environment conditions. The wind wheel device of this embodiment is used in a wind turbine generator set, and can be used for graded power generation under conditions from weak wind to hurricane environment. Its structure can withstand a 12-level hurricane and can generate electricity normally.
