DETAILED DESCRIPTION
[0022] 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 of the embodiments.
[0023] Reference Figure 1-Figure 5 A directionally adjustable wind power generator comprises a pillar 1, a rotating seat 2 is rotatably sleeved on the upper end of the pillar 1, a mounting seat 3 is fixedly mounted on the rotating seat 2, a generator body 4 is fixedly mounted on the mounting seat 3, a plurality of spherical grooves are provided on the side and the upper end of the pillar 1, a rolling assembly comprises a plurality of balls 8 respectively embedded in the plurality of spherical grooves, and the plurality of balls 8 are in rolling contact with the rotating seat 2.
[0024] The rotating seat 2 is rotatably mounted on the upper end of the pillar 1. The arrangement of multiple balls 8 can effectively reduce the friction between the rotating seat 2 and the pillar 1, making it easier for the rotating seat 2 to rotate on the upper end of the pillar 1, thereby facilitating the adjustment of the direction of the generator body 4.
[0025] A support column 5 is fixedly installed on the generator body 4, a guide plate 6 is fixedly installed on the upper end of the support column 5, a diverter plate 7 is symmetrically and tiltedly fixedly installed on one end of the guide plate 6, and both diverter plates 7 are provided with heat dissipation components for dissipating heat from the generator body 4, a locking component for locking the rotating seat 2 is provided on the pillar 1, and a rolling component for reducing friction is provided at the rotating connection between the rotating seat 2 and the pillar 1.
[0026] The guide plate 6 and the two diverter plates 7 are all installed at the rear end of the generator body 4, and one end of the guide plate 6 faces the blades of the generator body 4. The guide plate 6 can break the wind. When the direction of the blades of the wind turbine deviates from the wind direction, the wind broken by the guide plate 6 will hit the two diverter plates 7 respectively, and the wind forces hitting the two diverter plates 7 are different, which will apply an oblique force to the diverter plates 7 and the guide plates 6 as a whole. When the locking assembly releases the lock on the rotating seat 2, the rotating seat 2 will be driven to rotate under the action of the wind force until the blades of the generator body 4 face the wind direction. At this time, the wind direction is parallel to the guide plate 6, and the wind force of the broken wind hitting the two diverter plates 7 will be the same, and the rotating seat 2 will not rotate, so that the blades of the wind turbine automatically face the wind direction, effectively improving the power generation efficiency of the wind turbine.
[0027] The locking assembly includes a plurality of isosceles triangular blocks 9 fixedly mounted on the lower end of the rotating seat 2, an electrically controlled cylinder 10 fixedly mounted on the pillar 1, a moving rod 11 vertically slidably mounted on the pillar 1 through a support block, and a clamping block 12 fixedly mounted on the upper end of the moving rod 11. The plurality of triangular blocks 9 are arranged in a circle at the lower end of the rotating seat 2, the lower end of the moving rod 11 is fixedly connected to the output shaft of the electrically controlled cylinder 10 through a connecting block, the clamping block 12 is inserted between two adjacent triangular blocks 9, and guiding inclined surfaces are provided on both sides of the upper end of the clamping block 12, and the two inclined surfaces are respectively in contact with the inclined surfaces of two adjacent triangular blocks 9.
[0028] When it is necessary to release the lock on the rotating seat 2, the moving rod 11 is driven by the electric control cylinder 10 to move vertically downward, and then the moving rod 11 drives the block 12 to move vertically downward, and the block 12 is moved out from between two adjacent triangular blocks 9, thereby releasing the lock on the rotating seat 2. When the fan blades of the generator body 4 are facing the wind direction, the moving rod 11 is driven by the electric control cylinder 10 to move vertically upward, and then the block 12 is inserted between two adjacent triangular blocks 9. The setting of the inclined surfaces on both sides of the upper end of the block 12 can prevent the top of the block 12 from abutting against the lower end of the triangular block 9 when the block 12 is inserted between two adjacent triangular blocks 9.
[0029] A cavity 13 is provided in each of the two diverter plates 7. A plurality of air inlet holes 14 connected to the cavity 13 are provided on one side of the diverter plate 7 close to the guide plate 6. The heat dissipation assembly includes a connecting pipe 15 fixedly connected to the diverter plate 7 and a gas nozzle 16 fixedly installed at one end of the connecting pipe 15 away from the diverter plate 7. One end of the connecting pipe 15 is connected to the cavity 13, and the gas nozzle 16 faces the generator body 4.
[0030] When the wind blows onto the diverter plate 7, some wind will enter the cavity 13 through the air inlet 14 and then enter the connecting pipe 15 through the cavity 13. Finally, the wind collected by the gas nozzle 16 will blow onto the generator body 4, thereby cooling the generator.
[0031] The air inlet hole 14 is obliquely arranged on the diverter plate 7, and the air inlet hole 14 is parallel to the guide plate 6. The arrangement of the air inlet hole 14 facilitates the collection of more wind into the cavity 13, thereby achieving a better fanning effect.
[0032] In the present invention, when the direction of the fan blades of the wind turbine deviates from the wind direction, the wind broken by the guide plate 6 will hit the two diverter plates 7 respectively, and the wind forces hitting the two diverter plates 7 are different, thereby applying an oblique force to the diverter plates 7 and the guide plate 6 as a whole. When the locking assembly releases the lock on the rotating seat 2, the rotating seat 2 will be driven to rotate under the action of the wind force until the fan blades of the generator body 4 face the wind direction. At this time, the wind direction is parallel to the guide plate 6, and the wind forces hitting the two diverter plates 7 after the wind is broken will also be the same, and the rotating seat 2 will not rotate, so that the fan blades of the wind turbine automatically face the wind direction, effectively improving the power generation efficiency of the wind turbine.
[0033] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
