Description

[0001] The invention relates to the technical field of wind power generation, and in particular to a small wind power generator set. Background Art

[0002] Small wind turbines are power generation devices that can convert external wind kinetic energy into electrical energy and transmit it for use. They are a new type of sustainable and environmentally friendly power generation method and are widely used in areas with sufficient wind resources.

[0003] When existing small wind turbines are actually used, the output power of the internal generator is constant, so the rotation speed provided by the generator blades during power generation cannot be too large. If the external wind force is too strong and causes the rotation speed of the generator blades to be too fast, the output shaft speed of the internal generator will be too fast, which may easily cause the generator to overload and be damaged.

[0018] The present invention provides a small wind turbine generator set, which has the following beneficial effects:

[0019] 1. This small wind turbine has the advantage of being able to flexibly adjust the wind receiving angle. This wind turbine can monitor the wind speed and direction of the external wind in real time, and use the steering motor to drive the generator host according to the direction of the wind to adjust the overall wind receiving angle, so that the generator host can always face the wind direction, and can use the steering motor to drive the inclination angle of the power generation blades according to the inclination angle of the wind direction to flexibly adjust the inclination angle of the power generation blades, so that the power generation blades are always at the best wind receiving angle, so that the wind energy can be fully utilized and waste can be avoided.

When the wind is normal, the external wind can drive the generating blades to drive the input shaft and the output shaft to rotate at a normal speed, thereby driving the generator to generate electricity normally. When the external wind is too strong and the input shaft rotates too fast, the output shaft can be automatically stopped by the cooperation of the driven mechanism and the linkage mechanism, thereby avoiding damage to the generator load caused by excessive output shaft speed, thereby effectively protecting the generator.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Reference Figure 1 A small wind turbine generator set includes a supporting base plate 1, on which a plurality of fastening bolts are arranged, so that the small turbine generator set can be installed as a whole on the ground or on the roof.

[0042] Reference Figure 1-Figure 10 , the direction adjustment part is used to adjust the wind direction of the generator set, so that the generator set can always be in the best wind position, so as to make full use of wind energy;

[0043] The steering part includes a support column 2 fixedly mounted on a support base plate 1, a main generator 4 is mounted on the support column 2 through an adjusting mechanism, the adjusting mechanism includes a hydraulic rod 9 fixedly mounted in the support column 2, a support plate 3 is fixedly mounted on the hydraulic rod 9, a steering motor is fixedly mounted on the support plate 3, and the main generator 4 is fixedly mounted on the driving end of the steering motor.

[0044] The hydraulic rod 9 is activated to drive the support plate 3 and the main generator 4 thereon to move up and down, thereby adjusting the overall height of the main generator 4 to prevent the main generator 4 from being blocked, making it more conducive to wind power generation;

[0045] When the steering motor is started, it will drive the main generator 4 to adjust the horizontal angle, so that the main generator 4 can be rotated to the direction facing the wind, so that the main generator 4 is more susceptible to wind power generation and has higher power generation efficiency.

[0046] Reference Figure 1-Figure 5 In a further embodiment, a rotating disk 8 is rotatably mounted on the end of the power generation host 4, and a plurality of power generation blades 6 are mounted on the rotating disk 8 through a plurality of deflection mechanisms, and a detection mechanism is mounted on the power generation host 4;

[0047] The detection mechanism includes a detection seat 7 fixedly mounted on the upper part of the power generation host 4, a wind direction tail rod 5 fixedly mounted on the tail of the power generation host 4, a wind direction detection disk 11 fixedly mounted on the detection seat 7, a wind direction detection mark 10 rotatably mounted on the wind direction detection disk 11, and a detection trigger rod 12 matched with the wind direction detection disk 11 fixedly mounted on the wind direction detection mark 10;

[0048] The wind direction tail rod 5 is used to maintain the overall balance of the power generation host 4 and to naturally adjust the overall direction of the power generation host 4. The wind direction detection flag 10 can rotate under the external wind force and rotate until it always keeps facing the direction of the wind force, so as to detect the wind direction. When the wind direction detection flag 10 rotates under the action of wind force, it will drive the detection trigger rod 12 to rotate on the wind direction detection disk 11, thereby triggering the wind direction detection disk 11. When the wind direction detection flag 10 stops rotating, the position of the detection trigger rod 12 on the wind direction detection disk 11 is the real-time wind direction.

[0049] A wind direction detection sensor and a controller are provided in the main generator 4. The wind direction detection sensor is used to electronically monitor the wind direction and can be combined with the detection mechanism to make the wind direction detection more accurate. The controller is used to control the opening and closing of the electronic components in the generator set and to conduct signals between each other.

[0050] Reference Figure 2 as well as Figure 6-Figure 10 In a further embodiment, the deflection mechanism includes a blade rod 18 rotatably mounted on the rotating disk 8, a connecting ball is fixedly mounted on the lower end of the blade rod 18, and the power generation blade 6 is fixedly mounted on the blade rod 18, and a fine-tuning structure is installed between the blade rod 18 and the rotating disk 8;

[0051] The fine adjustment structure includes an adjustment motor 19 fixedly installed in the rotating disk 8, an adjustment gear 20 is fixedly installed on the driving end of the adjustment motor 19, and an adjustment gear ring 21 is fixedly installed on the fan blade rod 18, and the adjustment gear ring 21 is meshed with the adjustment gear 20;

[0052] When the detection mechanism cooperates with the wind direction detection sensor to detect the real-time and accurate wind direction, the controller will start and control multiple adjustment motors 19 to start, thereby driving multiple adjustment gears 20 to rotate, thereby driving the adjustment gears 20 to rotate. The rotation of the adjustment gears 20 will drive the wind blade rod 18 and the power generation wind blade 6 to rotate, and the inclination angle of the power generation wind blade 6 can be fine-tuned, so that the power generation wind blade 6 is always at the best wind receiving angle, so that the wind energy can be fully utilized.

[0053] An output shaft 23 is installed in the main generator 4 through a power generation mechanism. The power generation mechanism includes a carrier plate 17 fixedly installed in the main generator 4, on which a gearbox 13 and a generator 14 are fixedly installed. The output shaft 23 is rotatably installed on the gearbox 13, and the gearbox 13 cooperates with the generator 14. When the output shaft 23 rotates, it will increase speed under the cooperation of the gearbox 13 and drive the generator shaft in the generator 14 to rotate. At this time, the generator 14 will start to work and generate electricity.

[0054] Reference Figure 1 , Figure 3-Figure 4 , Figure 6-Figure 8 as well as Figure 10-Figure 16 The brake stop part is used to brake the output shaft 23 when the wind is strong, so as to prevent the generator shaft in the generator 14 from generating electricity too fast and causing overload and damage to the generator 14;

[0055] The brake part includes an input shaft 22 fixedly mounted on the rotating disk 8, and a connecting ball is rotatably mounted on the input shaft 22. The rotation of the plurality of power generation blades 6 will drive the input shaft 22 to rotate under the action of the connecting ball. A plurality of driven rollers 26 are rotatably mounted in the power generation host 4, and a driving internal gear ring 15 is installed between the plurality of driven rollers 26 and the input shaft 22 through a driven mechanism.

[0056] The driven mechanism includes a fixed ring fixedly installed in the main generator 4, and the driving internal gear ring 15 is rotatably installed in the fixed ring, each driven roller 26 is fixedly installed with a driven gear 27, and the input shaft 22 is fixedly installed with a driving gear 28, and the inner sides of the plurality of driven gears 27 are meshed with the driving gear 28, and the outer sides of the plurality of driven gears 27 are meshed with the driving internal gear ring 15;

[0057] The rotation of the input shaft 22 will drive the driving gear 28 thereon to rotate, and the rotation of the driving gear 28 will drive the multiple driven gears 27 to rotate. At this time, the driven gear 27 will be accelerated by the driving gear 28, that is, the rotation speed of the driven gear 27 is greater than the rotation speed of the driving gear 28. When the multiple driven gears 27 rotate, they will also drive the external driving inner gear ring 15 to rotate. The rotation speed of the driving inner gear ring 15 is relatively low, which can basically be kept equal to the rotation speed of the input shaft 22.

[0058] Reference Figure 10-Figure 14 In a further embodiment, a driven ring 16 is fixedly mounted on the output shaft 23, and a linkage mechanism is installed between the driven ring 16 and the driving inner gear ring 15, the linkage mechanism includes a limit disk frame 30 fixedly mounted in the driven ring 16, a limit ring 25 is rotatably mounted on the driven ring 16, a plurality of connecting rods 31 are fixedly mounted between the limit ring 25 and the driving inner gear ring 15, and a blocking structure is installed between the limit ring 25 and the driven ring 16;

[0059] The blocking structure includes a plurality of extrusion friction rollers 32 fixedly mounted on the limiting ring 25, and the plurality of extrusion friction rollers 32 are all in contact with the outer wall of the driven ring 16, and a plurality of rubber holders 33 are fixedly mounted on the driven ring 16, and the plurality of rubber holders 33 are all matched with the extrusion friction rollers 32;

[0060] When the inner gear ring 15 is driven to rotate, the plurality of limit rings 25 will be driven to rotate under the action of the plurality of connecting rods 31. Since the driven ring 16 is not in a locked state at this time (i.e., the driven ring 16 can rotate), the limit ring 25 will drive the plurality of extrusion friction rollers 32 to rotate when it rotates. When the extrusion friction rollers 32 rotate, they will be stuck on the rubber card seat 33, and the rubber card seat 33 will block the extrusion friction rollers 32. The extrusion friction force between the rubber card seat 33 and the extrusion friction rollers 32 will be greater than the rotational friction force between the driven ring 16 and the limit ring 25, so that if the extrusion friction rollers 32 want to rotate, they will only drive the rubber card seat 33 and the driven ring 16 to rotate together. When the driven ring 16 rotates, it will drive the output shaft 23 to rotate, and power generation can be performed. This is the power generation process under normal wind speed.

[0061] Reference Figure 10-12 as well as Figure 15-16 In a further embodiment, a limit box 34 is fixedly installed in the generator main unit 4 through a support rod, and a conduction structure is installed between the limit box 34 and a plurality of driven rollers 26, the conduction mechanism includes a driven box 29 rotatably sleeved on the outside of the driven roller 26, a built-in rubber ring 38 is fixedly installed in the driven box 29, and a conduction tube 36 is fixedly connected between the built-in rubber ring 38 and the limit box 34, a plurality of elastic squeezing rollers 24 matched with the built-in rubber ring 38 are fixedly installed on the driven roller 26, an elastic piston 37 is slidably installed in the limit box 34, a limit card plate 35 is fixedly installed on the elastic piston 37, and the limit card plate 35 matches with the limit disc frame 30;

[0062] When the external wind force is relatively large, the rotation speed of the input shaft 22 will increase, thereby increasing the rotation speed of the driven roller 26. When the driven roller 26 rotates at a high speed, the elastic squeezing roller 24 inside it will extend under the action of centrifugal force. When the elastic squeezing roller 24 extends, it will squeeze the built-in rubber ring 38 in the driven box 29, that is, during the rotation process, the air in the built-in rubber ring 38 will be pressed into the limit box 34 through the conduction tube 36. When the air in the limit box 34 increases, it will push the elastic piston 37 to move, thereby driving the limit card plate 35 to move. When the limit card plate 35 moves to contact the limit disk frame 30, it will first squeeze the limit disk frame 30, so that the limit disk frame 30 and the driven ring 16 are squeezed and decelerated under the action of the squeezing friction force. When the driven ring 16 and the limit disk frame 30 are decelerated to a certain extent, the limit card plate 35 will eventually engage with the limit disk frame 30, so that the limit disk frame 30 can be limited so that it cannot rotate.

[0063] When the limit disc frame 30 cannot rotate, the driven ring 16 and the output shaft 23 cannot rotate. At this time, the generator 14 will shut down, that is, the generator 14 can be automatically shut down when the external wind force is too strong, which can effectively avoid overload damage to the generator 14. When the driven ring 16 cannot rotate, the limit ring 25 continues to rotate to drive the multiple extrusion friction rollers 32 to rotate. At this time, the multiple extrusion friction rollers 32 will squeeze the rubber card seat 33 to compress it, so that the extrusion friction rollers 32 can press over the rubber card seat 33 and rotate normally, and will not affect the normal rotation of the limit ring 25.

[0064] When the external wind force decreases, the rotation speed of the driven roller 26 decreases, so that the elastic squeezing roller 24 will not be driven to extend and squeeze the built-in rubber ring 38. At this time, the elastic piston 37 will be reset and cooperate with the contraction of the built-in rubber ring 38 to press the air in the limit box 34 back into the built-in rubber ring 38 through the conductive tube 36, which can drive the limit card plate 35 to limit the limit, thereby releasing the limit of the limit disc frame 30 and the driven ring 16. At this time, the driven ring 16 will continue to rotate and drive the output shaft 23 to rotate normally to generate electricity;

[0065] A hydraulic column can be arranged in the main generator 4, a rubber friction ring can be arranged on the output shaft 23, and a locking extrusion rod can be arranged on the driving end of the hydraulic column. When the external wind force continues to increase and the rotation speed of the power generation fan blades 6 continues to increase, in order to avoid damage to the power generation fan blades 6, the hydraulic column can be started to move the locking extrusion rod on its driving end and squeeze the rubber friction ring, and under the action of the extrusion friction force, the rubber friction ring and the output shaft 23 are gradually decelerated, and the pressure of the hydraulic column can be adjusted according to the size of the external wind force and the rotation speed of the output shaft 23, so as to increase the extrusion force of the locking extrusion rod, thereby improving the deceleration efficiency of the output shaft 23, until the output shaft 23 cannot rotate, thereby locking multiple power generation fan blades 6 and preventing them from rotating, thereby avoiding damage to them.

[0066] The specific operation mode of this small generator set is as follows:

[0067] Wind angle adjustment: The hydraulic rod 9 is started to drive the support plate 3 and the main generator 4 thereon to move up and down, thereby adjusting the overall height of the main generator 4 to avoid the main generator 4 being blocked, making it more conducive to wind power generation. The steering motor is started to drive the main generator 4 to adjust the horizontal angle, so that the main generator 4 can be rotated to the direction facing the wind, so that the main generator 4 is more susceptible to wind power generation and has higher power generation efficiency;

[0068] The wind direction tail rod 5 is used to maintain the overall balance of the power generation host 4 and to naturally regulate the overall direction of the power generation host 4. The wind direction detection mark 10 can rotate under the external wind force and rotate to always keep facing the direction of the wind force, so as to detect the wind direction. When the wind direction detection mark 10 rotates under the action of wind force, it will drive the detection trigger rod 12 to rotate on the wind direction detection disk 11, thereby triggering the wind direction detection disk 11. When the wind direction detection mark 10 stops rotating, the position of the detection trigger rod 12 on the wind direction detection disk 11 is the real-time wind direction. The wind direction detection sensor is used to electronically monitor the wind direction and can be used with the detection mechanism to make the wind direction detection more accurate.

[0069] When the detection mechanism cooperates with the wind direction detection sensor to detect the real-time and accurate wind direction, the controller will start and control multiple adjustment motors 19 to start, thereby driving multiple adjustment gears 20 to rotate, thereby driving the adjustment gears 20 to rotate. The rotation of the adjustment gears 20 will drive the wind blade rod 18 and the power generation wind blade 6 to rotate, and the inclination angle of the power generation wind blade 6 can be fine-tuned, so that the power generation wind blade 6 is always at the best wind receiving angle, so that the wind energy can be fully utilized.

[0070] Wind power generation and brake protection: The rotation of multiple power generation blades 6 will drive the input shaft 22 to rotate under the action of the connecting ball, and the rotation of the input shaft 22 will drive the driving gear 28 thereon to rotate, and the rotation of the driving gear 28 will drive the multiple driven gears 27 to rotate. At this time, the driven gear 27 will be accelerated by the driving gear 28, that is, the speed of the driven gear 27 is greater than the speed of the driving gear 28. The rotation of the multiple driven gears 27 will drive the external driving inner gear ring 15 to rotate. The speed of the driving inner gear ring 15 is relatively low, which can be basically the same as the speed of the input shaft 22;

[0071] When the inner gear ring 15 is driven to rotate, the plurality of limit rings 25 will be driven to rotate under the action of the plurality of connecting rods 31. Since the driven ring 16 is not in a locked state at this time (i.e., the driven ring 16 can rotate), the limit ring 25 will drive the plurality of extrusion friction rollers 32 to rotate when it rotates. When the extrusion friction rollers 32 rotate, they will be stuck on the rubber card seat 33. The rubber card seat 33 will block the extrusion friction rollers 32. The extrusion friction force between the rubber card seat 33 and the extrusion friction rollers 32 will be greater than the rotational friction force between the driven ring 16 and the limit ring 25. Therefore, if the extrusion friction rollers 32 want to rotate, they will only drive the rubber card seat 33 and the driven ring 16 to rotate together. When the driven ring 16 rotates, it will drive the output shaft 23 to rotate. When the output shaft 23 rotates, it will increase the speed under the cooperation of the gearbox 13 and drive the generator shaft in the generator 14 to rotate. At this time, the generator 14 will start to work and generate electricity. This is the power generation process under normal wind speed.

[0072] When the external wind force is relatively large, the rotation speed of the input shaft 22 will increase, thereby increasing the rotation speed of the driven roller 26. When the driven roller 26 rotates at a high speed, the elastic squeezing roller 24 inside it will extend under the action of centrifugal force. When the elastic squeezing roller 24 extends, it will squeeze the built-in rubber ring 38 in the driven box 29, that is, during the rotation process, the air in the built-in rubber ring 38 will be pressed into the limit box 34 through the conduction tube 36. When the air in the limit box 34 increases, it will push the elastic piston 37 to move, thereby driving the limit card plate 35 to move. When the limit card plate 35 moves to contact the limit disk frame 30, it will first squeeze the limit disk frame 30, so that the limit disk frame 30 and the driven ring 16 are squeezed and decelerated under the action of the squeezing friction force. When the driven ring 16 and the limit disk frame 30 are decelerated to a certain extent, the limit card plate 35 will eventually engage with the limit disk frame 30, so that the limit disk frame 30 can be limited so that it cannot rotate.

[0073] When the limit plate frame 30 cannot rotate, the driven ring 16 and the output shaft 23 cannot rotate, and the generator 14 will stop at this time. That is, when the external wind force is too strong, the generator 14 can be automatically shut down, which can effectively avoid overload damage to the generator 14.

[0074] When the external wind force decreases, the rotation speed of the driven roller 26 decreases and will not drive the elastic squeezing roller 24 to extend and squeeze the built-in rubber ring 38. At this time, the elastic piston 37 will be reset and cooperate with the contraction of the built-in rubber ring 38 to press the air in the limit box 34 back into the built-in rubber ring 38 through the conduction tube 36, which can drive the limit of the limit card plate 35, thereby releasing the limit of the limit disc frame 30 and the driven ring 16. At this time, the driven ring 16 will continue to rotate and drive the output shaft 23 to rotate normally to generate electricity.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
