Description

Technical Field

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

[0002] A vertical-axis wind turbine (VAWT) is a wind power generation device whose main feature is that the rotor's axis of rotation is perpendicular to the ground. Compared to traditional horizontal-axis wind turbines (HAWTs), VAWTs are better able to adapt to varying wind directions and are not affected by wind shifts, making them suitable for use in urban environments or areas with unstable wind conditions.

[0003] A Chinese patent with patent publication number CN212250328U discloses a vertical axis wind turbine, comprising a wind rotor, a generator and a support column; wherein: the wind rotor comprises an upper wind rotor and a lower wind rotor with opposite rotation directions, and is fixed to an inner rotor and a motor housing correspondingly, so that the inner rotor and the armature winding fixed to the housing rotate in opposite directions, and the generator speed is the sum of the speeds of the upper and lower wind rotors; the generator speed is increased and the torque is reduced, which can correspondingly reduce the diameter of the wind rotor; combined with the blade angle adjustment, it can rotate in a light wind environment and ensure safe operation in strong winds.

[0004] However, the current vertical axis wind turbines have the following problems: In typhoon weather, the strong winds brought by the typhoon will exceed the wind speed range designed to withstand the vertical axis wind turbine. The strong winds in the typhoon will bring violent wind fluctuations, causing the wind turbine blades to vibrate or become unbalanced, thereby causing the wind turbine blades to suffer severe impacts, resulting in cracks, breakage or distortion. Therefore, we propose a vertical axis wind turbine. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a vertical axis wind turbine that solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a vertical axis wind turbine, comprising a base, the top of the base is rotatably connected to a hollow column, the top of the inner wall of the hollow column is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a rotating column, two small thread grooves are provided at the lower part of the outer wall of the rotating column, the two small thread grooves of the rotating column are threadedly connected to a threaded sleeve 1, the outer wall of the threaded sleeve 1 is fixedly connected to a hexagonal block, three side surfaces of the hexagonal block are fixedly connected to an articulated block 1, and the three articulated blocks 1 are articulated with blades on one side away from the hexagonal block, the upper part of the outer wall of the hollow column is fixedly connected to a hexagonal fixing block, three side surfaces of the hexagonal fixing block are fixedly connected to an articulated block 2, and the articulated block 2 is fixedly connected on one side away from the hexagonal fixing block On the outer wall of the three blades, the wind will push multiple blades to rotate, and the rotation of multiple blades will cause the hollow column to rotate through the hinge block 2, and the hollow column will drive the generator in the base to generate electricity. When there is a typhoon, the staff will start the motor through the external controller, and the output shaft of the motor will cause the rotating column to rotate. The rotation of the rotating column will cause the two threaded sleeves to move upward along the two small thread grooves. The upward movement of the two threaded sleeves will drive the blades to move toward the direction of the hollow column through the two hinge blocks 1, and then with the cooperation of the two hinge blocks 1 and the hinge block 2, the blades will move in a downward arc trajectory toward the direction of the hollow column, thereby reducing the area of ​​the blades affected by the typhoon, avoiding large vibrations or imbalances in the blades, causing the blades to suffer severe impacts, resulting in cracks, breakage or distortion.

[0007] According to the above technical solution, the outer wall of the hollow column is fixedly connected with a supporting hollow block, and the outer wall of the blade is fixedly connected with a placement block. When the blade moves toward the hollow column, the placement block will move to the inside of the supporting hollow block.

[0008] According to the above technical solution, the supporting hollow block is located on the displacement track of the placement block.

[0009] According to the above technical solution, the inner wall of the blade is provided with an anti-winding device, and the anti-winding device includes a U-shaped block, and the U-shaped block is fixedly installed on the inner wall of the blade. Both sides of the U-shaped block are fixedly connected with a moving frame, and the inner walls of the two moving frames are slidably connected with a cutting knife. A spring 2 is provided between the cutting knife and the moving frame. When the blade moves toward the direction of the hollow column, it will drive the U-shaped block to move, and the movement of the U-shaped block will drive the moving frame to move, and the movement of the moving frame will drive the cutting knife to move.

[0010] According to the above technical solution, a vertical rod passes through and slides on the top of the movable frame, and an arc plate is fixedly connected to the top of the vertical rod. A spring 1 is arranged between the arc plate and the movable frame, and the vertical rod is inserted into the top of the cutting knife. The hinge block 2 is fixedly connected to an L-shaped block on the hinge seat on one side of the hexagonal fixed block, and a soft ring is fixedly connected to the middle part of the outer wall of the hollow column. The movement of the movable frame will drive the vertical rod to move, and the movement of the vertical rod will drive the arc plate to move. When the arc plate moves to the inclined surface of the L-shaped block, the L-shaped block will limit the movement of the arc plate, so that the arc plate will drive the vertical rod to no longer be inserted into the cutting knife. At this time, the cutting knife will conflict with the soft ring. Under the interaction force between the soft ring and the cutting knife, the soft ring will push the cutting knife to move to the inside of the movable frame and move the spring 2.

[0011] According to the above technical solution, an upper side of the L-shaped block is provided with an inclined surface, the inclined surface of the L-shaped block is located on the displacement track of the arc plate, and the soft ring is located on the displacement track of the cutting knife.

[0012] According to the above technical solution, a dispersion device is provided at the bottom of the rotating column, and the dispersion device includes a large threaded rod, the top of the large threaded rod is fixedly connected to the bottom of the rotating column, the outer wall of the large threaded rod is threadedly connected with a threaded sleeve 2, the outer wall of the threaded sleeve 2 is fixedly connected with a fixing ring, the outer wall of the fixing ring is rotatably connected with a rotating ring, the outer wall of the rotating ring is fixedly connected with a connecting rod, and the end of the connecting rod away from the rotating ring is fixedly connected with an arc-shaped dispersion plate, the bottom of the connecting rod is fixedly connected with a fixing rod, and the bottom of the fixing rod is fixedly connected with a wind vane. The rotation of the rotating column will drive the large threaded rod to rotate, the rotation of the large threaded rod will cause the threaded sleeve 2 to move, the movement of the threaded sleeve 2 will drive the fixing ring to move, the movement of the fixing ring drives the rotating ring to move, the movement of the rotating ring will drive the connecting rod to move, and the movement of the connecting rod drives the arc-shaped dispersion plate to move. At the same time, because the arc-shaped dispersion plate is staggered with the blades, and the rotation of the large threaded rod makes the movement of the threaded sleeve 2 faster than that of the threaded sleeve 1.

[0013] According to the above technical solution, the arc-shaped dispersion plate and the blades are staggered.

[0014] The present invention provides a vertical axis wind turbine with the following beneficial effects: (1) The present invention cooperates with the motor, the rotating column, the threaded sleeve 1, the small thread groove, the hinge block 1, the blade, the hollow column, and the hinge block 2, so that when the two hinge blocks 1 and the hinge block 2 cooperate, the blade will move in a downward arc trajectory toward the hollow column, thereby reducing the area of ​​the blade impacted by the typhoon, avoiding large-scale vibration or imbalance of the blade, causing the blade to suffer serious impact, resulting in cracks, breakage or distortion; at the same time, through the cooperation of the blade, the hollow column, the supporting hollow block, and the placement block, the supporting hollow block provides an embedded support for the placement block, making the interaction force between the supporting hollow block and the placement block more balanced, and at the same time making the blade more stable, reducing the impact of the typhoon on the blade, and thus improving the stability of the overall structure.

[0015] (2) The present invention cooperates with the blades, hollow columns, U-shaped blocks, moving frames and cutting blades so that the movement of the cutting blades can cut off the plastic and other entanglements that are blown away by the typhoon and entangled on the surfaces of the hinge block 1 and the hinge block 2, thereby preventing the plastic and other entanglements from remaining on the surfaces of the hinge block 1 and the hinge block 2. When the blades are in use, the plastic and other entanglements accumulate more and more on the surfaces of the hinge block 1 and the hinge block 2, thereby consuming more energy to drive the blades to rotate, which will reduce the efficiency of the equipment and reduce the output of wind power generation or other power systems, and even affect the operating stability of the entire system. At the same time, through the cooperation of the moving frame, cutting blades, vertical rods, arc plates, spring 1, spring 2, L-shaped blocks and soft rings, the cutting blades stay in the moving frame, avoiding the cutting blades from being exposed to the typhoon environment, helping to protect the cutting blades from collisions with objects blown up by the typhoon or other unnecessary friction, thereby extending the service life of the cutting blades.

[0016] (3) The present invention cooperates with the large threaded rod, the second threaded sleeve, the fixed ring, the rotating ring, the connecting rod, and the arc-shaped dispersion plate, so that the rotation of the large threaded rod causes the movement of the second threaded sleeve to be faster than the movement of the first threaded sleeve. Therefore, when the blades are fixed, the arc-shaped dispersion plate just blocks the blades. The arc-shaped dispersion plate can disperse the wind force blown toward the blades by the typhoon, thereby avoiding the problem that the wind force blowing toward the blades is too strong and causes damage to the blades. At the same time, the arc-shaped dispersion plate can also block objects blown up by the typhoon, thereby avoiding the problem that the objects hit the blades and cause damage to the blades. At the same time, through the cooperation of the rotating ring, the connecting rod, the arc-shaped dispersion plate, the fixed rod, and the wind vane, when the wind direction of the typhoon changes, the wind vane will rotate. The wind vane will drive the connecting rod to rotate through the fixed rod. The rotation of the connecting rod will drive the rotating ring and the arc-shaped dispersion plate to rotate, so that the arc-shaped dispersion plate can remain facing the wind direction.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0020] See also Figure 1-Figure 7One embodiment of the present invention is: a vertical axis wind turbine, including a base 1, the top of the base 1 is rotatably connected to a hollow column 2, the top of the inner wall of the hollow column 2 is fixedly connected to a motor 3, the output shaft of the motor 3 is fixedly connected to a rotating column 4, two small thread grooves 5 are provided at the lower part of the outer wall of the rotating column 4, the two small thread grooves 5 of the rotating column 4 are threadedly connected to a threaded sleeve 6, the outer wall of the threaded sleeve 6 is fixedly connected to a hexagonal block 7, three side surfaces of the hexagonal block 7 are fixedly connected to a hinge block 10, and the three hinge blocks 10 are hinged with blades 11 on the side away from the hexagonal block 7, and the outer wall of the hollow column 2 is provided with a plurality of small thread grooves 5. The square is fixedly connected with a hexagonal fixing block 12, and three side surfaces of the hexagonal fixing block 12 are fixedly connected with a hinge block 2 13. The side of the hinge block 2 13 away from the hexagonal fixing block 12 is fixedly connected to the outer wall of the three blades 11. Through the arrangement of the above structure, the two hinge blocks 10 cooperate with the hinge block 2 13, and the blade 11 will move in a downward arc trajectory toward the direction of the hollow column 2, thereby reducing the area of ​​the blade 11 affected by the typhoon, avoiding large-scale vibration or imbalance of the blade 11, causing the blade 11 to suffer severe impact, resulting in cracks, breakage or distortion.

[0021] The outer wall of the hollow column 2 is fixedly connected to a supporting hollow block 14, and the outer wall of the blade 11 is fixedly connected to a placing block 15. The supporting hollow block 14 is located on the displacement trajectory of the placing block 15. Through the setting of the above structure, the supporting hollow block 14 provides an embedded support for the placing block 15, so that the interaction force between the supporting hollow block 14 and the placing block 15 is more balanced, and at the same time, the blade 11 is more stable, reducing the impact of typhoon on the blade 11 and thus improving the stability of the overall structure.

[0022] The inner wall of the blade 11 is provided with an anti-winding device 8, which includes a U-shaped block 81, which is fixedly mounted on the inner wall of the blade 11, and a movable frame 82 is fixedly connected to both sides of the U-shaped block 81, and the inner walls of the two movable frames 82 are slidably connected with a cutting knife 83, and a spring 2 87 is provided between the cutting knife 83 and the movable frame 82. Through the setting of the above structure, the movement of the cutting knife 83 will be blown away by the typhoon and cut off the plastic and other entanglements that are entangled on the surfaces of the hinge block 10 and the hinge block 2 13, thereby preventing the plastic and other entanglements from remaining on the surfaces of the hinge block 10 and the hinge block 2 13. As a result, when the blade 11 is in use, as the plastic and other entanglements accumulate more and more on the surfaces of the hinge block 10 and the hinge block 2 13, more energy will be consumed to drive the blade 11 to rotate, which will reduce the efficiency of the equipment, and reduce the output of wind power generation or other power systems, and even affect the operating stability of the entire system.

[0023] A vertical rod 84 passes through and slides through the top of the moving frame 82, and an arc plate 85 is fixedly connected to the top of the vertical rod 84. A spring 1 86 is provided between the arc plate 85 and the moving frame 82. The vertical rod 84 is inserted into the top of the cutting knife 83, and the hinge block 2 13 is fixedly connected to the hinge seat on one side of the hexagonal fixed block 12 with an L-shaped block 88. A soft ring 89 is fixedly connected to the middle part of the outer wall of the hollow column 2. An inclined surface is set on the upper side of one side of the L-shaped block 88. The inclined surface of the L-shaped block 88 is located on the displacement trajectory of the arc plate 85, and the soft ring 89 is located on the displacement trajectory of the cutting knife 83. Through the arrangement of the above structure, the cutting knife 83 stays in the moving frame 82, avoiding the cutting knife 83 from being exposed to the typhoon environment, helping to protect the cutting knife 83 from collision with objects blown up by the typhoon or other unnecessary friction, thereby extending the service life of the cutting knife 83.

[0024] When in use, natural wind will drive multiple blades 11 to rotate, and the rotation of multiple blades 11 will cause the hollow column 2 to rotate through the hinge block 2 13, and the hollow column 2 will drive the generator in the base 1 to generate electricity. When there is a typhoon, the staff will start the motor 3 through the external controller, and the output shaft of the motor 3 will cause the rotating column 4 to rotate. The rotation of the rotating column 4 will cause the two threaded sleeves 16 to move upward along the two small thread grooves 5. The upward movement of the two threaded sleeves 16 will drive the blades 11 to move toward the direction of the hollow column 2 through the two hinge blocks 10, and then under the cooperation of the two hinge blocks 10 and the hinge block 2 13, the blades 11 will move in a forward direction. The arc trajectory below moves toward the direction of the hollow column 2, thereby reducing the area of ​​the blade 11 affected by the typhoon, avoiding large-scale vibration or imbalance of the blade 11, causing the blade 11 to suffer serious impact, resulting in cracks, breakage or distortion; when the blade 11 moves toward the direction of the hollow column 2, the placement block 15 will move to the inside of the supporting hollow block 14, so the supporting hollow block 14 provides an embedded support for the placement block 15, making the interaction force between the supporting hollow block 14 and the placement block 15 more balanced, and at the same time making the blade 11 more stable, reducing the impact of the typhoon on the blade 11 and thus improving the stability of the overall structure.

[0025] When the blade 11 moves toward the hollow column 2, it will drive the U-shaped block 81 to move, and the movement of the U-shaped block 81 will drive the moving frame 82 to move, and the movement of the moving frame 82 will drive the cutting knife 83 to move. The movement of the cutting knife 83 will cut off the plastic and other entanglements that are blown away by the typhoon and entangled on the surfaces of the hinge block 10 and the hinge block 2 13, thereby preventing the plastic and other entanglements from remaining on the surfaces of the hinge block 10 and the hinge block 2 13. As a result, when the blade 11 is in use, due to the accumulation of plastic and other entanglements on the surfaces of the hinge block 10 and the hinge block 2 13, more energy will be consumed to drive the blade 11 to rotate, which will reduce the efficiency of the equipment and reduce the output of wind power generation or other power systems, and even affect the stable operation of the entire system. Qualitative; The movement of the moving frame 82 will drive the vertical rod 84 to move, and the movement of the vertical rod 84 will drive the arc plate 85 to move. When the arc plate 85 moves to the inclined surface of the L-shaped block 88, the L-shaped block 88 will restrict the movement of the arc plate 85, so that the arc plate 85 will drive the vertical rod 84 to no longer be inserted into the cutting knife 83. At this time, the cutting knife 83 will contact the soft ring 89. Under the interaction force between the soft ring 89 and the cutting knife 83, the soft ring 89 will push the cutting knife 83 to move toward the inside of the moving frame 82 and move the spring 2 87, so that the cutting knife 83 will stay in the moving frame 82, avoiding the cutting knife 83 from being exposed to the typhoon environment, helping to protect the cutting knife 83 from collision with objects blown up by the typhoon or other unnecessary friction, thereby extending the service life of the cutting knife 83.

[0026] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a dispersion device 9 is provided at the bottom of the rotating column 4, and the dispersion device 9 includes a large threaded rod 91. The top of the large threaded rod 91 is fixedly connected to the bottom of the rotating column 4. The outer wall of the large threaded rod 91 is threadedly connected to a threaded sleeve 2 92. The outer wall of the threaded sleeve 2 92 is fixedly connected to a fixing ring 93. The outer wall of the fixing ring 93 is rotatably connected to a rotating ring 94. The outer wall of the rotating ring 94 is fixedly connected to a connecting rod 95. The end of the connecting rod 95 away from the rotating ring 94 is fixedly connected to an arc-shaped dispersion plate 96. The bottom of the connecting rod 95 is fixedly connected to a fixing rod 97. The bottom of the fixing rod 97 is fixedly connected to a wind vane 98. The arc-shaped dispersion plate 96 and the blade 11 are staggered. Through the arrangement of the above structure, the rotation of the large threaded rod 91 causes the threaded sleeve 2 to rotate. The movement of sleeve 2 92 is faster than that of threaded sleeve 1 6. Therefore, when the blade 11 is fixed, the arc-shaped dispersion plate 96 just blocks the blade 11. The arc-shaped dispersion plate 96 can disperse the wind force blown toward the blade 11 by the typhoon, thereby preventing the wind force blowing toward the blade 11 from being too strong, causing damage to the blade 11. At the same time, the arc-shaped dispersion plate 96 can also block objects blown up by the typhoon, preventing objects from hitting the blade 11 and causing damage to the blade 11. At the same time, when the wind direction of the typhoon changes, the wind vane 98 will rotate, and the wind vane 98 will drive the connecting rod 95 to rotate through the fixing rod 97. The rotation of the connecting rod 95 will drive the rotating ring 94 and the arc-shaped dispersion plate 96 to rotate, so that the arc-shaped dispersion plate 96 can remain on the side facing the wind direction.

[0027] When in use, the rotation of the rotating column 4 will drive the large threaded rod 91 to rotate, and the rotation of the large threaded rod 91 will cause the threaded sleeve 2 92 to move. The movement of the threaded sleeve 2 92 will drive the fixing ring 93 to move, and the movement of the fixing ring 93 will drive the rotating ring 94 to move. The movement of the rotating ring 94 will drive the connecting rod 95 to move, and the movement of the connecting rod 95 will drive the arc-shaped dispersion plate 96 to move. At the same time, since the arc-shaped dispersion plate 96 is staggered with the blade 11, and the rotation of the large threaded rod 91 makes the movement of the threaded sleeve 2 92 faster than the movement of the threaded sleeve 1 6, when the blade 11 is fixed, the arc-shaped dispersion plate 96 is just right for the blade 11. The arc-shaped dispersion plate 96 can disperse the wind force blown toward the blades 11 by the typhoon, thereby preventing the wind force blowing toward the blades 11 from being too strong and causing damage to the blades 11. At the same time, the arc-shaped dispersion plate 96 can also block objects blown up by the typhoon, thereby preventing objects from hitting the blades 11 and causing damage to the blades 11. At the same time, when the wind direction of the typhoon changes, the wind vane 98 will rotate, and the wind vane 98 will drive the connecting rod 95 to rotate through the fixed rod 97. The rotation of the connecting rod 95 will drive the rotating ring 94 and the arc-shaped dispersion plate 96 to rotate, so that the arc-shaped dispersion plate 96 can keep facing the side of the wind direction.

[0028] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
