Description

Technical Field

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

[0002] Wind power generation equipment is a device that converts wind energy into electrical energy. The key component of existing wind power generation equipment is the wind rotor (usually composed of several blades). When wind blows, the wind rotor blades rotate due to the action of wind force. Since the direction of wind changes, the direction of wind and the direction of wind rotor blades cannot always remain perpendicular during the actual use of wind power generation equipment. When the wind direction changes and is not perpendicular to the direction of wind rotor blades, the area of ​​blades affected by wind decreases, resulting in a decrease in the power of the blades being affected by wind, a decrease in the rotation speed of the wind rotor blades, and a decrease in the efficiency of blade rotation due to wind, which ultimately leads to a decrease in wind energy utilization and a decrease in power generation efficiency.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 5 As shown, the detection mechanism includes a support rod 201, the support rod 201 is fixedly connected to the lower side of the cabin 102, the upper end of the support rod 201 is rotatably connected to a rotating rod 202, the upper end of the rotating rod 202 is fixedly connected to a weather vane 203 located outside the cabin 102, and the middle part of the rotating rod 202 is fixedly connected to two one-way gears 204 symmetrically distributed up and down, and the two one-way gears 204 symmetrically distributed up and down are both located inside the cabin 102, the upper one-way gear 204 can rotate counterclockwise, and the lower one-way gear 204 can rotate clockwise Rotation: Two fixed blocks 205 symmetrically distributed front and back are fixedly connected in the cabin 102, and the two fixed blocks symmetrically distributed front and back are both slidably connected with racks 206. The two racks 206 symmetrically distributed front and back are respectively rotatably connected with adjacent connecting rods 109, and the two symmetrically distributed racks 206 are respectively engaged with adjacent one-way gears 204. The two symmetrically distributed connecting rods 109 are both provided with limiting mechanisms for limiting the rotation direction of the cabin 102, and the rotation directions of the two symmetrically distributed one-way gears 204 are opposite.

[0022] like Figure 6 and Figure 7As shown, the limiting mechanism includes two first cylindrical shells 301 symmetrically distributed front and back, the two first cylindrical shells 301 symmetrically distributed front and back are both fixed to the left side of the inner wall of the cabin 102, the right sides of the two symmetrically distributed first cylindrical shells 301 are both fixed with cylindrical tubes 302, the upper sides of the two symmetrically distributed connecting rods 109 are both fixed with second cylindrical shells 303, the two symmetrically distributed cylindrical tubes 302 are respectively slidably connected to the adjacent second cylindrical shells 303, and the two symmetrically distributed first cylindrical shells 303 are fixed to the right sides of the two symmetrically distributed connecting rods 109. 01 are both limitedly slidably connected with a slide bar 304, and the two symmetrically distributed slide bars 304 are both slidably connected with a limited block 305. When the second rotating wheel 108 moves to the left, the right side of the adjacent limited block 305 contacts the left end of the second rotating wheel 108, and the limited block 305 blocks the adjacent second rotating wheel 108 from moving to the left. When the second rotating wheel 108 moves to the left and then resets to the right, the lower end of the adjacent limited block 305 contacts the side wall of the second rotating wheel 108, and the side wall of the second rotating wheel 108 blocks the adjacent The limit block 305 moves downward, and the upper sides of the two symmetrically distributed limit blocks 305 are connected to the adjacent slide bars 304 with second compression springs 306. The cabin 102 is provided with a speed regulating mechanism for adjusting the rotation speed of the cabin 102. The upper sides of the two symmetrically distributed slide bars 304 are provided with protrusions, the height of the protrusions is greater than the diameter of the cylindrical tube 302, and the diameter of the protrusions is smaller than the inner diameter of the first cylindrical shell 301. When the slide bar 304 moves upward, the upper side of the protrusions on the upper side of the slide bar 304 is in contact with the adjacent slide bars 304. The adjacent first cylindrical shell 301 is in contact with the adjacent first cylindrical shell 301. At this time, the hydraulic pressure can still flow into the first cylindrical shell 301 through the adjacent cylindrical tube 302. The protrusion prevents the slide bar 304 from moving directly upward to block the connection between the adjacent first cylindrical shell 301 and the adjacent cylindrical tube 302, thereby preventing a malfunction caused by the hydraulic pressure being unable to flow into the adjacent first cylindrical shell 301 through the cylindrical tube 302. The adjacent second rotor 108 is limited by the limit block 305, so that the nacelle 102 will not deflect until the wind direction deflection reaches a certain degree.

[0023] like Fig. 9As shown, the speed regulating mechanism includes two blocking blocks 401 symmetrically distributed front and back, the lower sides of the two symmetrically distributed blocking blocks 401 are fixed to the upper side of the cabin 102, the upper side of the rotating rod 202 is fixed with the rotating block 402, the two symmetrically distributed blocking blocks 401 are located at the front and rear sides of the rotating block 402, the two symmetrically distributed blocking blocks 401 are used to limit the left and right swing angles of the rotating block 402, the two symmetrically distributed worm gears 107 are both provided with a reset component for resetting the second rotating wheel 108, and the two symmetrically distributed second rotating wheels 108 are both set as round tables The diameter of the second rotor 108 gradually increases from the right side to the left side, and the side surfaces of the two symmetrically distributed second rotors 108 are parallel to the side surfaces of the first rotor 105. When the second rotor 108 contacts the first rotor 105, the further to the left the position of the second rotor 108 is, the greater the transmission ratio between the first rotor 105 and the second rotor 108 is, and the first rotor 105 with the same speed drives the adjacent second rotor 108 to rotate faster. By adjusting the transmission ratio of the second rotor 108 and the first rotor 105, the deflection speed of the cabin 102 is different when the wind direction changes at different angles.

[0024] like Fig.11 As shown, the reset assembly includes two symmetrically distributed snap rings 501, which are respectively fixed to the left ends of adjacent worm gears 107, and a third compression spring 502 is connected between the two symmetrically distributed snap rings 501 and the adjacent second rotating wheel 108, and the elastic coefficients of the two symmetrically distributed third compression springs 502 are both smaller than the elastic coefficient of the first compression spring 111.

[0025] When the wind power generation equipment is working normally, the wind drives the blades 103 to rotate, and the rotation of the blades 103 drives the output shaft of the gearbox 104 to rotate, and the output shaft of the gearbox 104 drives the generator inside to generate electricity, and the output shaft of the gearbox 104 drives the first impeller 105 to rotate.

[0026] In the above-mentioned power generation process, when the wind direction and the direction of the blade 103 deviate, the wind drives the weather vane 203 to rotate, and the rotation of the weather vane 203 drives the rotating rod 202 to rotate, and the rotation of the rotating rod 202 drives the two one-way gears 204 to rotate. Since the rotating rod 202 rotates unidirectionally, the unidirectional rotation of the rotating rod 202 can only drive one one-way gear 204 to rotate, and the rotation of the one-way gear 204 drives the rack 206 meshing with it to move to the left, and the rack 206 pushes the adjacent connecting rod 109 to move, and the adjacent second rotating wheel 108 moves to the left and is blocked by the adjacent limit block 305. The second rotating wheel 108 blocks the adjacent connecting block 110 from moving to the left, and the connecting rod 109 moves to the left to compress the first compression spring 111 between it and the adjacent connecting block 110.

[0027] During the compression of the first compression spring 111, the connecting rod 109 pushes the second cylindrical shell 303 to move leftward, and the second cylindrical shell 303 moves leftward to form a negative pressure between it and the cylindrical tube 302, so that the transmission slide rod 304 moves upward, and the slide rod 304 drives the limit block 305 to move upward.

[0028] During the upward movement of the above-mentioned limit block 305, when the wind direction angle changes slightly, the rotation angle of the wind vane 203 is small, the rotation angle of the wind vane 203 driven by the rotating rod 202 is small, and the rotation amplitude of the one-way gear 204 driven by the rotating rod 202 is small, so that the transmission rack 206 moves a small distance to the left, and the rack 206 moves a small distance to the left to the transmission second cylindrical shell 303, so that the sliding rod 304 drives the limit block 305 to move upward a small distance, and the limit block 305 moves upward a small distance and fails to release its limit on the second rotating wheel 108, and the second rotating wheel 108 cannot frictionally cooperate with the first rotating wheel 105.

[0029] During the upward movement of the above-mentioned limit block 305, when the wind direction angle changes sufficiently to cause the limit block 305 to move to release the limit on the second rotating wheel 108, the first compression spring 111 resets and pushes the connecting block 110 to move to the left, and the connecting block 110 pushes the second rotating wheel 108 to move to the left. The second rotating wheel 108 moves to the left and compresses the third compression spring 502. The second rotating wheel 108 moves to the left and frictionally cooperates with the first rotating wheel 105.

[0030] After the second rotating wheel 108 cooperates with the first rotating wheel 105 , the first rotating wheel 105 drives the second rotating wheel 108 to rotate, the second rotating wheel 108 drives the worm 107 to rotate, and the rotation of the worm 107 drives the nacelle 102 to rotate on the tower 101 .

[0031] In the process of the first rotor 105 driving the second rotor 108 to rotate, when the deflection angle of the wind direction increases, the deflection angle of the wind vane 203 increases, the wind vane 203 drives the rotating rod 202 to increase the rotation angle, the rotating rod 202 drives the rotating block 402 to increase the rotation angle, the rotating block 402 rotates The increased angle drives the adjacent rack 206 to move to the left. The rack 206 pushes the adjacent connecting rod 109 to the left to move an increased distance, and the connecting rod 109 pushes the adjacent second rotor 108 to the left through the adjacent first compression spring 111 and the adjacent connecting block 110. The radius of the second rotor 108 and the first rotor 105 is reduced, so that the transmission ratio of the second rotor 108 and the first rotor 105 is increased, and the second rotor 108 drives the worm 107 to increase the rotation speed, so that the rotation of the nacelle 102 becomes faster, so that the greater the angle deflection, the faster the nacelle 102 changes direction.

[0032] When the second rotating wheel 108 moves to the left, when the rotation reaches a certain angle, the blocking block 401 restricts the rotating block 402 from continuing to rotate, and the rotating block 402 drives the weather vane 203 to stop rotating. At this time, the first rotating wheel 105 and the second rotating wheel 108 cooperate in transmission on the rightmost side, the rotation speed of the worm 107 reaches the maximum value, and the steering speed of the cabin 102 reaches the maximum value, until the cabin 102 drives the rotating block 402 to rotate and separate from the blocking block 401.

[0033] In the above-mentioned steering process of the cabin 102, when the cabin 102 rotates and is about to reach the direction of the wind vane 203, the rack 206 moves to the right, the rack 206 drives the connecting rod 109 to move to the right, the connecting rod 109 drives the connecting block 110 to move to the right, the reset of the third compression spring 502 drives the second rotating wheel 108 to move to the right, the connecting rod 109 drives the second cylindrical shell 303 to move to the right, the second cylindrical shell 303 moves to the right and drives the sliding rod 304 to move downward, the sliding rod 304 drives the second compression spring 306, the second rotating wheel 108 blocks the limit block 305 from moving downward, and the sliding rod 304 drives the second compression spring 306. 04 moving downward will compress the second compression spring 306. When the cabin 102 continues to rotate to the position of the wind vane 203, the second wheel 108 disengages from the first wheel 105, and the second wheel 108 moves to the right to release the limit on the limit block 305. The second compression spring 306 resets and pushes the limit block 305 to move downward and reset. At this time, the third compression spring 502 also returns to its original position. After the first wheel 105 and the second wheel 108 disengage, the second wheel 108 stops rotating, the worm 107 stops rotating, and the cabin 102 also stops rotating. At this time, the direction of the wind power generation equipment rotates to the direction of the wind vane 203.

[0034] Example 2: Fig.12 and Fig.13As shown, it also includes a speed measuring mechanism, which is arranged on the rotating rod 202. The speed measuring mechanism is used to stop the steering after the wind power generation equipment reaches the rated power. The speed measuring mechanism includes two fixed rods 601 symmetrically distributed up and down, and the two symmetrically distributed fixed rods 601 are fixed to the inside of the rotating rod 202. The rotating rod 202 is rotatably connected with six clamping blocks 602 symmetrically distributed up and down and circumferentially, and the six symmetrically and circumferentially distributed clamping blocks 602 are respectively slidably connected to the adjacent one-way gears 204. The six symmetrically and circumferentially distributed clamping blocks 602 are connected to the adjacent fixed rods 601 with springs, and the rotating rod 202 is fixed with an upper There are two symmetrically distributed fixing rings 603 at the bottom, and a torsion spring 604 is connected between the lower side of the two symmetrically distributed fixing rings 603 and the upper side of the adjacent one-way gear 204. The upper side of the rotating rod 202 is rotatably connected with a sealing ring 605, and the upper side of the rotating rod 202 is rotatably connected with a rotating block 606. The sealing ring 605 is slidably connected with three circumferentially distributed anemometers 607, and tension springs 608 are connected between the three circumferentially distributed anemometers 607 and the rotating block 606. The anemometer 607 is rotated centrifugally to adsorb and move the block 602 into the rotating rod 202, so that the cabin 102 does not turn when the wind speed is too high.

[0035] During the above-mentioned power generation process, the circumferentially distributed anemometers 607 are rotated by the wind. When the wind speed increases to affect the normal operation of the generator in the nacelle 102, the circumferentially distributed anemometers 607 rotate and move outward under the action of eccentricity, so that the adjacent tension springs 608 are stretched, so that negative pressure is formed in the rotating rod 202, so that the transmission block 602 moves into the rotating rod 202, and the spring between the block 602 and the fixed rod 601 is compressed. The block 602 moves inward to release the limit on the one-way gear 204, and releases the fixation of the one-way gear 204 on the rotating rod 202. At this time, the rotation of the rotating rod 202 will not drive the one-way gear 204 to rotate, and the rotation of the rotating rod 202 causes the torsion spring 604 to twist and store force.

[0036] After the wind speed decreases, the torsion spring 604 resets and drives the rotating rod 202 to reset. The rotating rod 202 resets and drives the wind vane 203 to rotate to the direction of the cabin 102. At this time, the speed of the anemometer 607 decreases, and the tension spring 608 resets to make the anemometer 607 move into the rotating rod 202. The negative pressure in the rotating rod 202 decreases, and the spring reset between the block 602 and the fixed rod 601 pushes the block 602 to reset. The block 602 resets and fixes the rotating rod 202 and the one-way gear 204. At this time, the wind blows the wind vane 203 to rotate again, and the wind vane 203 drives the rotating rod 202 to rotate. The rotating rod 202 drives the one-way gear 204 to rotate, and the wind receiving direction of the blade 103 can be readjusted according to the wind direction.

[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
