Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to a lever-type torque boosting device for a wind power generator. Background Art

[0002] After being put into operation, wind power generation has a very low operating cost because it does not consume other energy sources, and it is a clean energy because it does not consume other polluting energy sources. Therefore, it is vigorously developed. Each wind turbine generator set is mainly composed of: foundation, tower, nacelle, blades, hub, and generator. The power required for wind turbines to generate electricity comes entirely from the wind acting on the blades. The higher the wind speed, the higher the blade speed, and the greater the power generation.

[0003] In the absence of wind, the impeller cannot obtain power and cannot generate electricity. If the wind speed does not reach the designed wind speed requirement of the impeller, the impeller cannot obtain sufficient kinetic energy and will not generate electricity.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Embodiment 1:

[0031] A wind turbine lever-type torque boosting device, such as Figure 1-7 As shown, it includes a wind turbine tower 1, a wind turbine cabin 5 is fixed to the outer wall of the top of the wind turbine tower 1, a main shaft 9 is rotatably connected to the inner wall of the wind turbine cabin 5, a conductive slip ring 8 is arranged on the outer wall of the main shaft 9, and the conductive slip ring 8 is electrically connected to the power generation equipment arranged inside the wind turbine cabin 5 through a transmission line, a hub 3 is fixed to the outer wall of the main shaft 9, a plurality of wind turbine blades 2 are fixed to the outer wall of the hub 3, a connecting block 12 is fixed to the outer wall of the wind turbine blade 2, a duct 4 is fixed to the outer wall of the connecting block 12, a plurality of fixing rods 14 are fixed to the inner wall of the duct 4, a mounting tube 11 is fixed to the outer wall of one side of the fixing rod 14, a motor 10 is fixed to the outer wall of one side of the mounting tube 11, an output shaft of the motor 10 is connected to a rotating shaft 15 through a coupling, and a plurality of blades 16 are fixed to the outer wall of the rotating shaft 15;

[0032] The inner wall of the installation tube 11 is provided with an electronic speed regulator and a power supply, which are electrically connected to the motor 10 respectively; the outer wall of the installation tube 11 is fixed with a wire tube 28, and the outer wall of the conductive slip ring 8 is provided with a power supply line 6, which is electrically connected to the power supply inside the installation tube 11;

[0033] The outer wall of the power supply line 6 is sleeved with a plurality of line brackets 7, and the line brackets 7 are fixed on the outer wall of the wind turbine blade 2;

[0034] A guide ring 13 is fixed to the outer wall of the duct tube 4 .

[0035] The power generation device located inside the wind turbine cabin 5 can supply power to the power supply inside the mounting tube 11 through the conductive line connected to the conductive slip ring 8, thereby controlling the motor 10 to drive the multiple blades 16 on the outer wall of the rotating shaft 15 to rotate. When the blades 16 rotate, a certain pulling force will be generated on one end of the wind turbine blade 2, thereby utilizing the lever principle to amplify the pulling force multiples, so that the wind turbine blade 2 can still have a torque output of several thousand Newton meters in the absence of wind or in a breeze below the design wind speed of the wind blade. At the same time, it can be superimposed with the torque generated by the wind to generate electricity, and the power generation efficiency is higher, thereby greatly increasing the impeller output torque and improving the power generation efficiency.

[0036] At the same time, the staff can adjust the speed of the motor 10 through the electronic speed regulator.

[0037] Torque is a moment that causes an object to rotate. In physics, torque is a special moment, which is equal to the product of force and lever arm. The international unit of torque is Newton per meter (Nm). Therefore, when the pulling force is the same, the longer the lever arm, the greater the torque. For the same force of 50 Newtons, when the lever arm is 1 meter long, the torque is 50 Newton meters, and when the lever arm is 10 meters long, the torque is 500 Newton meters. Therefore, under the same force, the longer the lever arm, the greater the torque.

[0038] Usually, three wind turbine blades 2 are fixed to the outer wall of the hub 3, and the length of the wind turbine blades 2 is more than ten meters. Therefore, a certain force is applied to the top of the wind turbine blade 2 and then multiplied by ten to obtain the torque generated by the single wind turbine blade 2. At the same time, a small tension system consisting of a duct tube 4, a motor 10 and a blade 16 is installed at one end of the three wind turbine blades 2 on the outer wall of the hub 3 to ensure the dynamic balance of the three wind turbine blades 2 during rotation. Therefore, the torque generated by the three-blade wind turbine generator set is multiplied by three to obtain the final torque generated by the wind turbine blades 2 of the three-blade wind turbine generator. The small tension system installed on a single wind turbine blade 2 can provide a tension of 50 Newtons, and 50 Newtons*10 meters*3=1500 Newton meters.

[0039] 1 kg force is approximately equal to 10 Newtons. In this embodiment, the length of the wind turbine blade 2 is ten meters. Taking the motor 10 with a 40A electronic speed regulator as an example, the 40A electronic speed regulator weighs 26 grams. In this embodiment, the model of the motor 10 is a 5008KV335 outer rotor brushless motor with a diameter of 5.85 cm, a height of 3.8 cm, and a weight of 162 grams. In this embodiment, the model of the blade 16 is a 1755 propeller, which is made of carbon fiber and weighs only a few grams. When the motor 10 runs at 70% of the rated speed, the power is 0.3 kilowatts, and the pulling force generated is 2.6 kg, which is approximately equal to 26 Newtons. Because the motor 10 is light and small in size, a small pulling system consisting of a wind turbine blade 2, two sets of ducts 4, a motor 10 and a blade 16 is used for calculation. 26 Newtons * 2 sets = 52 Newtons, 52 Newtons * 10 meters = 520 Newton-meters, 520 Newton-meters * 3 pieces = 1560 Newton-meters, and the electric power required by six 5008KV335 outer rotor motors is 1.8 kilowatts.

[0040] It can be seen from the above calculation structure that the motor 10 only needs to consume 1.8 kilowatts of electricity to increase the torque by 1560 Nm. The overall weight of the motor, electronic speed regulator and blades added to the outer wall of a single wind turbine blade 2 is about 190 grams. The total weight of the ten-meter power supply line 6 and the line bracket 7 on the outer wall of the power supply line 6 does not exceed 3 kilograms. Therefore, the existing wind turbine blade 2 can fully withstand it.

[0041] The motor 10 can run continuously under the condition of 70% speed output. The force generated by the motor 10 driving the blades 16 can be superimposed on the torque generated by the wind force acting on the wind turbine blades 2 through the torque amplified by the lever principle, thereby realizing windless rotation power generation and superimposed power generation with wind force, thereby improving the overall power generation efficiency of the wind turbine generator set.

[0042] When this embodiment is in use, the power generation device located inside the wind turbine cabin 5 can supply power to the power supply inside the mounting tube 11 through the conductive line connected to the conductive slip ring 8, thereby controlling the motor 10 to drive the multiple blades 16 on the outer wall of the rotating shaft 15 to rotate. When the blades 16 rotate, a certain pulling force is generated on one end of the wind turbine blade 2, thereby utilizing the lever principle to amplify the pulling force multiples, so that the wind turbine blade 2 can still have a torque output of several thousand Newton meters in the absence of wind or in a breeze below the design wind speed of the wind blade, and at the same time, it can be superimposed with the torque generated by the wind to generate electricity, thereby achieving higher power generation efficiency.

[0043] The staff can adjust the speed of the motor 10 through the electronic speed regulator, and at the same time install a small tension system consisting of a duct 4, a motor 10 and a blade 16 at one end of the three wind turbine blades 2 on the outer wall of the hub 3 to ensure the dynamic balance of the three wind turbine blades 2 during rotation.

At the same time, the elastic telescopic rods 22 can support and cushion the mounting plates 18 through their own gravity, cushion the wind resistance encountered by the mounting plates 18 during rotation, and improve the overall stability of the mounting plates 18.

[0052] At the same time, the photovoltaic panel 19 located on the outer wall of the mounting plate 18 can generate electricity through sunlight, thereby generating electricity through sunlight under low wind speed and no wind conditions, and then transmitting the electricity generated by the photovoltaic panel 19 to the motor 10, so that the motor 10 does not need to draw electricity from the power generation equipment inside the wind turbine cabin 5, and can rotate under low wind speed and no wind conditions, thereby improving the stability of the torque boosting device during operation.
