In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a high-power vertical axis turbine wind power generation power configuration device, please refer to fig. 1 to 3, and the high-power vertical axis turbine wind power generation power configuration device comprises a main shaft 1, a plurality of speed-increasing structures 2 and a plurality of generators 3, wherein the main shaft 1 is used for being fixedly arranged with the vertical axis turbine power generation device, the input end of each speed-increasing structure 2 is in driving connection with the main shaft 1, and each generator 3 is in driving connection with the output end of the corresponding speed-increasing structure 2. In the present embodiment, the main shaft 1 is used to be fixedly disposed with the rotor 81 of the vertical axis turbine power generation apparatus. In this embodiment, the main shaft 1 transmits mechanical energy converted from wind energy, and in other embodiments, the main shaft 1 may also transmit other mechanical energy converted from wind energy, such as water energy, and the like, which is not limited herein.
According to the invention, the plurality of speed-increasing structures 2 are matched with the plurality of generators 3, and each generator 3 is in driving connection with the output end of the corresponding speed-increasing structure 2, so that the plurality of speed-increasing structures 2 (which can be small-power speed-increasing structures 2) are adopted to drive the plurality of generators 3 (which can be small-power generators 3) respectively to replace a single large-scale speed-increasing structure, a power distribution mode is realized, and the design, manufacture, operation and maintenance costs of the speed-increasing structures 2 and the generators 3 are reduced.
Specifically, a plurality of speed increasing structures 2 are distributed on the periphery of the main shaft 1 to drive the main shaft 1 together, so that the total power of 10MWh of the vertical axis turbine wind driven generator 3 group can be decomposed into several MWh-level generators 3.
The generator 3 may be a horizontal generator set or a vertical generator set, and the steering structure 23 may be reduced for the vertical generator 3, but the vertical generator 3 has a high requirement on bearing selection and lubrication, and has a high requirement on installation accuracy, and in this embodiment, the horizontal generator 3 is used.
The arrangement form of each speed-increasing structure 2 is determined according to the selection of the generator 3, when the generator 3 adopts a vertical generator 3, each speed-increasing structure 2 comprises a first-stage speed-increasing stage 21 and a second-stage speed-increasing stage 22, one end of the first-stage speed-increasing stage 21 is in driving connection with the main shaft 1, one end of the second-stage speed-increasing stage 22 is in driving connection with the other end of the first-stage speed-increasing stage 21, and the other end of the second-stage speed-increasing stage 22 is in driving connection with the generator 3, so that a steering structure 23 is not needed; when the horizontal generator 3 is adopted as the generator 3, each of the speed-increasing structures 2 includes a first-stage speed-increasing stage 21, a second-stage speed-increasing stage 22 and a steering structure 23, one end of the first-stage speed-increasing stage 21 is in driving connection with the main shaft 1, one end of the second-stage speed-increasing stage 22 is in driving connection with the other end of the first-stage speed-increasing stage 21, one end of the steering structure 23 is in driving connection with the other end of the second-stage speed-increasing stage 22, and the other end of the steering structure is in driving connection with the generator 3.
Specifically, referring to fig. 4, the first-stage speed-increasing stage 21 includes a first driving gear 211 and a first driven gear 212, the first driving gear 211 is fixed to the main shaft 1, and the first driven gear 212 is engaged with the first driving gear 211 and is fixed to one end of the second-stage speed-increasing stage 22. In this embodiment, the first step speed-increasing stages 21 of the plurality of speed-increasing structures 2 may include a first driving gear 211 and a plurality of second driven gears 223, the first driving gear 211 is in driving connection with the main shaft 1, and the plurality of second driven gears 223 are respectively engaged with the first driving gear 211. The first driving gear 211 is drivingly connected to the main shaft 1, such that a gear shaft of the first driving gear 211 is fixed to the main shaft 1, so that the main shaft 1 rotates to drive the first driving gear 211 to rotate. The first driving gear 211 and the main shaft 1 may be connected together through a flexible coupling 9, or may be connected in other connection manners, which is not limited herein. The flexible coupling 9 can also ensure the concentricity of the shafts at the upper end and the lower end and has certain compensation amount, thereby ensuring that the speed-increasing structure 2 and the vertical axis turbine wind driven generator 3 are connected concentrically with a certain compensation amount integrally. Referring to fig. 2, the first driving gears 211 of the plurality of speed increasing structures 2 may share one driving gear 211 (that is, a plurality of first driven gears 212 meshed with the first driving gear 211 are circumferentially arranged on the first driving gear 211 to form a plurality of first driving gears 211 and first driven gears 212 of the speed increasing structures 2), or the first driving gears 211 of the plurality of speed increasing structures 2 may be individually disposed (not shown in the figure).
The first speed increasing ratio of the first speed increasing stage 21 is greater than the second speed increasing ratio of the second speed increasing stage 22, and the first driving gear 211 selects a gear with a larger diameter, so that the gear has sufficient space to distribute the second speed increasing stage 22 on the periphery of the first driving gear 211, and the first driven gear 212 obtains a high rotating speed under the first speed increasing ratio.
The first driving gear 211 with a large diameter is a heavy device which can be directly seated on the support of the tower 6 through the main shaft 1, and a thrust bearing which can bear the dynamic load and the static load of the combination of the first driving gear 211 and the main shaft 1 is arranged at the lowest part of the main shaft 1. The pitch circle diameter of the first driving gear 211 is increased, a plurality of first driven gears 212 (the specific number can be determined according to actual requirements) can be arranged on the periphery of the first driving gear 211 to share the total power of the wind driven generator 3 group, so that the power borne by each first driven gear 212 is reduced, the requirement on the strength of a single tooth of the first driving gear 211 is reduced, the requirement on the strength of a single tooth of the first driven gear 212 is also reduced, the design and the manufacture of the high-power first driving gear 211 and the first driven gear 212 are facilitated, but the pitch circle diameter of the first driving gear 211 cannot be too large, and the manufacturing cost and the transportation cost are increased due to the fact that the pitch circle diameter is too large.
The second speed increasing stage 22 may be a planetary speed increasing gear structure, or may be another transmission structure. The first driven gear 212, after attaining a preset high rotational speed, transmits the rotational speed to the second step speed-up stage 22. Referring to fig. 5, the second-stage speed-increasing stage 22 includes a crankshaft 221, a second driven gear 223, a gear ring 222 and a second driving gear 224, one end of the crankshaft 221 is fixedly connected to the other end of the first-stage speed-increasing stage 21, the second driven gear 223 is fixedly disposed with the driving shaft of the generator, the gear ring 222 is fixed to the tower 6 and has an axis coaxial with the axis of the second driven gear 223, the second driving gear 224 is fixedly and drivingly connected to the crankshaft 221 so as to drive the second driving gear 224 to rotate by the rotation of the crankshaft 221, and the second driving gear 224 is engaged with the gear ring 222 and the second driven gear 223. The second-stage speed-increasing stages 22 of the plurality of speed-increasing structures 2 are respectively arranged on the periphery of the main shaft 1 and are respectively in transmission connection with the corresponding first-stage speed-increasing stages 21. The rotation speed of the first driven gear 212 is transmitted to the second driving gear 224 through the crankshaft 221, and the second driving gear 224 performs rotation and revolution motion along the gear ring 222 under the rotation of the crankshaft 221, and increases speed during the revolution process, and drives the second driven gear 223 to rotate during the rotation process. The ring gear 222 is in this embodiment fixed to the tower 6. The pitch diameters of the second driving gear 224 and the second driven gear 223 are determined to determine the speed-increasing ratio of the second driving gear 224 and the second driven gear 223, and when the pitch diameters of the fixed ring gear 222 and the driving gear are determined while the second driving gear 224 rotates along the fixed ring gear 222, a speed-increasing ratio is also determined, and actually there are two speed increases in the second speed-increasing stage 22, and the speed-increasing ratio of the second speed-increasing stage 22 should be the product of the two speed-increasing ratios.
When the horizontal generator is adopted, the second driven gear 223 is connected with the steering structure 23, and the vertical rotating speed is converted into the horizontal direction required by the horizontal generator through the steering structure 23.
Specifically, referring to fig. 6, the steering structure 23 includes a driving bevel gear 231 and a driven bevel gear 232, the driving bevel gear 231 is in driving connection with the other end of the second-stage speed-increasing stage 22 to drive the driving bevel gear 231 to rotate through the second-stage speed-increasing stage 22, the driven bevel gear 232 is in meshing fit with the driving bevel gear 231, and the driven bevel gear 232 (specifically, a driven gear shaft 233 of the driven bevel gear 232) is in driving connection with the driving shaft of the generator 3 to drive the generator to generate electricity through the rotation of the driven bevel gear 232. The speed increasing ratio of the steering structure 23 adopting the bevel gear for increasing speed cannot be too high, the speed increasing ratio is too high, the size of the driving bevel gear 231 is larger, so that the driving bevel gear is difficult to manufacture, and the upper tooth meshing adjustment of the driven bevel gear 232 is difficult, so that the bevel gear is suitable for the speed increasing ratio below 2 MWh.
Each generator 3 is selectively connected with the output end of the corresponding speed-increasing structure 2 in a driving manner, so that the power generated by the vertical axis wind turbine 3 group for obtaining the wind energy can be adapted, when the wind speed is low, a part of the generators 3 can be selected to be connected with the output end of the corresponding speed-increasing structure 2 in a driving manner (in the embodiment, one generator 3 is selected to be connected with the output end of the corresponding speed-increasing structure 2), the starting torque is low at the moment, and the small wind speed can enable one generator 3 to work effectively; when the wind speed is gradually increased, a plurality of generators 3 can be put into operation in succession, in the embodiment, 80% of the generators 3 can be put into operation when the wind speed reaches the rated wind speed, 100% of the generators 3 can be put into operation when the super-high wind speed occurs, and if the wind speed is increased again, all the generators 3 are in overload operation under the condition that the design working condition allows. The arrangement widens the effective output power of the vertical axis turbine wind power generation device, greatly improves the annual full generation hours of the vertical axis turbine wind power generation device, and brings great economic benefit for the vertical axis turbine wind power generation device. In the present embodiment, a clutch 4 is connected between each of the generators 3 and the output end of the corresponding speed increasing structure 2; the high-power vertical axis turbine wind power generation power configuration device further comprises a controller, wherein the controller is electrically connected with the clutch 4, so that the clutch of the clutch 4 can be controlled through the controller to control whether the corresponding generator 3 is connected with the speed increasing structure 2 or not.
In order to increase the safety of the high-power vertical axis turbine wind power generation power configuration device, the high-power vertical axis turbine wind power generation power configuration device further comprises a brake device 5, and the brake device 5 is installed on the periphery of the main shaft 1 and used for braking the main shaft 1. In the present embodiment, the brake device 5 includes a hydraulic band-type brake device 5, and the hydraulic band-type brake device 5 includes a hydraulic cylinder 51, a hydraulic modulator 52, and a brake plate 53. The number of the hydraulic band-type brake devices 5 is multiple, the multiple hydraulic band-type brake devices 5 are arranged on the periphery of the main shaft 1, in the embodiment, the number of the hydraulic band-type brake devices 5 is four, when the unacceptable rotating speed of the vertical axis turbine wind power generation device occurs, the two symmetrical groups of hydraulic band-type brake devices 5 are started to apply the holding force to the main shaft 1 to brake, the rotating speed is reduced, then the other two groups of brake assemblies are started to stop the vertical axis turbine power generation device, and thus the brake devices 5 with the buffering effect can be implemented. When the device is installed, the brake device 5 is located on the bracket of the upright post of the tower 6.
The tower frame 6 is formed by assembling and connecting section steel, supports the roller thrust bearing 7, and enables the dynamic load and the static load of the main shaft 1 to be transmitted to the tower frame 6 through the rolling thrust bearing, so that the static load and the dynamic load born by the speed-increasing structure 2 are greatly reduced.
