Description

Technical Field

[0001] This invention belongs to the field of generator equipment technology, specifically a wind power generation device and method. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] However, in existing technologies, the wind force required for the actual start-up of existing wind turbines varies, which means that the wind force required for the rotor to rotate normally cannot properly drive the rotor of the wind turbine. This leads to wind force variations that make it difficult for existing wind turbines to generate electricity continuously. At the same time, because the actual installation structure of existing wind turbines is relatively fixed, they cannot easily adjust their structure according to the actual use environment to meet the needs of efficient operation under different usage conditions, resulting in poor actual performance of existing wind turbines. Summary of the Invention

[0004] The purpose of this invention is to provide a wind power generation device and method that can be adapted to different wind conditions, ensure continuous power generation, and adjust its structure according to the actual usage environment to improve the actual efficiency of the device.

[0005] The technical solution adopted in this invention is as follows: A wind power generation device and method, comprising: a support mechanism, the support mechanism including a base frame and a support pipe, the support pipe being connected and disposed at the top of the base frame; and

[0006] An adjustment mechanism includes a top frame, a mounting frame, an extension shaft, a connecting shaft, an impeller, a first generator body, a second generator body, and an adjustment component. The extension shaft is slidably inserted into the support tube. The top frame is fixedly connected to the top of the extension shaft. The mounting frame is connected to the top of the top frame. The connecting shaft is rotatably connected to the top of the mounting frame. The mounting shaft is inserted into the top of the connecting shaft. The impeller is sleeved on the outer surface of the mounting shaft. The first generator body and the second generator body are both fixedly connected to the bottom surface inside the top frame. The adjustment component is disposed on the mounting frame and the top frame.

[0007] The inner wall of the support tube has a limiting groove, and the bottom surface of the support tube is rotatably connected to a support threaded rod, the bottom end of which extends into the bottom frame.

[0008] The outer surface of the supporting threaded rod is fitted with an adjusting worm gear, the inner wall of the bottom frame is rotatably connected to an adjusting worm, the adjusting worm and the adjusting worm gear mesh, and a sealing plate is fixedly connected to one side of the outer surface of the bottom frame by bolts.

[0009] The outer surface of the extension shaft is fixedly connected to a limiting block, which is slidably inserted into the limiting groove.

[0010] The outer surfaces of both the connecting shaft and the mounting shaft are fitted with mounting rings, and the two mounting rings are fixedly connected by bolts.

[0011] The adjusting component includes a side shaft, a connecting gear, a connecting gear ring, a limiting gear ring, a limiting gear, and a limiting assembly. The side shaft is rotatably connected to the top surface inside the bottom frame, and the top end of the side shaft extends into the interior of the mounting frame. The bottom end of the side shaft is fixedly connected to the input end of the second generator body. The connecting gear is sleeved on the outer surface of the side shaft. The connecting gear ring is rotatably connected to the bottom surface inside the mounting frame, and the connecting gear ring meshes with the connecting gear. The limiting gear ring is fixedly connected inside the connecting gear ring, and the limiting gear is sleeved on the input end of the first generator body. The limiting assembly is disposed on the connecting shaft.

[0012] The limiting assembly includes an extension frame, a fixed block, a movable block, an adjusting bolt, a counterweight frame, a first locking block, and a second locking block. The extension frame is fixedly connected to the bottom end of the connecting shaft, the fixed block is fixedly connected to the top of the extension frame, a sliding rod is fixedly connected to one outer surface of the fixed block, the movable block is slidably sleeved on the outer surface of the sliding rod, the adjusting bolt is rotatably disposed on the top of the extension frame, and one end of the adjusting bolt is rotatably connected to the movable block, the counterweight frame is slidably sleeved on the outer surface of the sliding rod, and the first locking block and the second locking block are both fixedly connected to the bottom of the counterweight frame.

[0013] The outer surface of the slide rod is fitted with a limiting spring, and the two ends of the limiting spring are respectively attached to the moving block and the counterweight frame.

[0014] The extension frame has a limit opening at the bottom, the top of the counterweight frame slides through the limit opening, multiple counterweight blocks are equidistantly inserted inside the counterweight frame, and fixing bolts slide through the bottom of the counterweight frame at equal intervals. The bottom end of each fixing bolt is threadedly connected to the bottom of the corresponding counterweight block.

[0015] A wind power generation method includes the following steps:

[0016] S1. Structural Adjustment: The base frame allows the equipment to be stably installed in the designated usage position. Then, by rotating the adjusting worm gear, the rotating adjusting worm gear, in conjunction with the adjusting worm wheel, drives the supporting threaded rod to rotate. Subsequently, the rotating supporting threaded rod, under the position restriction of the limit block and the limit groove, adjusts the usage height of the extension shaft. With the support of the extension shaft, the top frame, mounting frame, connecting shaft, and mounting shaft can support the impeller to a certain height, allowing the impeller to be fully blown by the wind.

[0017] S2. Condition Switching: Using a smaller first generator body and a larger second generator body, under low wind force, the impeller, in conjunction with the mounting shaft, drives the connecting shaft to rotate slowly. This, in turn, causes the connecting shaft to slowly rotate the extension frame. Supported by the moving block and limit spring, the counterweight frame drives the second locking block to engage with the limit gear, simultaneously moving the first locking block away from the limit gear ring. This allows the slowly rotating extension frame, in conjunction with the counterweight frame and the second locking block, to synchronously drive the limit gear to rotate. The limit gear then drives the smaller first generator body to rotate, enabling normal operation of the smaller generator body under low wind force. As the wind force gradually increases, the impeller, in conjunction with the mounting shaft, will drive the connecting shaft to rotate rapidly. This rapid rotation of the connecting shaft will then drive the extension frame to rotate rapidly. As the rotation speed of the extension frame increases... This allows the counterweight frame and counterweight blocks to compress the limiting spring under force, enabling the counterweight frame to move the second locking block away from the limiting gear. Simultaneously, it allows the first locking block to engage with the limiting gear ring, allowing the rotating extension frame to rotate through the first locking block. This, in turn, allows the limiting gear ring, in conjunction with the linkage gear ring, linkage gear, and side shaft, to drive the larger second generator body. This enables the equipment to generate electricity under different wind conditions. Furthermore, depending on the long-term wind conditions, the adjusting bolt can be rotated to compress the adjusting limiting spring by moving the moving block. By adding or removing counterweight blocks, the force required for the counterweight frame to compress the limiting spring and engage the first locking block with the limiting gear ring can be adjusted. This allows for the replacement of impellers of different specifications, ensuring that different impellers can be used normally under various wind conditions.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, during use, a smaller first generator body and a larger second generator body are used. Under the influence of a small wind force, the impeller, in conjunction with the mounting shaft, drives the connecting shaft to rotate slowly. This, in turn, causes the connecting shaft to drive the extension frame to rotate slowly. At this time, supported by the moving block and the limiting spring, the counterweight frame drives the second locking block to engage with the limiting gear, while simultaneously driving the first locking block away from the limiting gear ring. This allows the slowly rotating extension frame, in conjunction with the counterweight frame and the second locking block, to synchronously drive the limiting gear to rotate. Consequently, the limiting gear drives the smaller first generator body to rotate, enabling the smaller first generator body to operate normally under a small wind force. As the wind force gradually increases, the impeller, in conjunction with the mounting shaft, will drive the connecting shaft to rotate rapidly. The rapidly rotating connecting shaft will drive the extension frame to rotate rapidly. As the rotation speed of the extension frame increases, the... The counterweight frame and counterweight blocks are designed to compress the limiting spring under force, causing the counterweight frame to move the second locking block away from the limiting gear. Simultaneously, the first locking block engages with the limiting gear ring, allowing the rotating extension frame to rotate via the first locking block. This, in turn, enables the limiting gear ring, in conjunction with the linkage gear ring, linkage gear, and side shaft, to drive the larger second generator body. This allows the equipment to generate electricity under varying wind conditions. Furthermore, by adjusting the adjusting bolt according to long-term wind conditions, the adjusting bolt can compress the adjusting limiting spring via the moving block. Adding or removing counterweight blocks adjusts the pressure of the counterweight frame on the limiting spring, ensuring the first locking block engages with the limiting gear ring. This allows for the replacement of impellers of different specifications, ensuring their proper functioning under varying wind conditions and improving the equipment's overall performance.

[0020] (2) In this invention, when in use, the bottom frame enables the equipment to be stably set in the designated use position. Then, by rotating and adjusting the worm gear, the rotating worm gear, in conjunction with the adjusting worm wheel, drives the supporting threaded rod to rotate. Subsequently, the rotating supporting threaded rod adjusts the use height of the extension shaft under the position restriction of the limiting block and the limiting groove. Then, under the support of the extension shaft, the top frame, the mounting frame, the connecting shaft, and the mounting shaft can support the impeller to a certain height, so that the impeller can be fully blown by the wind. This allows the equipment to adjust its own structure according to the actual use environment, thereby improving the actual use effect of the equipment. Attached Figure Description

The mounting shaft 208 is inserted into the top of the connecting shaft 207. The impeller 209 is sleeved on the outer surface of the mounting shaft 208. The first generator body 204 and the second generator body 205 are both fixedly connected to the bottom surface inside the top frame 201. The adjusting components are disposed on the mounting frame 206 and the top frame 201. A limiting block 203 is fixedly connected to the outer surface of shaft 202. The limiting block 203 is slidably inserted into the limiting groove 107. Mounting rings are fitted on the outer surfaces of both the connecting shaft 207 and the mounting shaft 208. The two mounting rings are fixedly connected by bolts. The adjusting components include a side shaft 210, a connecting gear 212, a connecting gear ring 214, a limiting gear ring 213, a limiting gear 215, and a limiting assembly. The side shaft 210 is rotatably connected to the top surface inside the bottom frame 101, and the top end of the side shaft 210 extends into the mounting frame 206. The bottom end of the side shaft 210 is fixedly connected to the input end of the second generator body 205. The connecting gear 212 is fitted on the outer surface of the side shaft 210. The connecting gear ring 214 is rotatably connected to the bottom surface inside the mounting frame 206. The connecting gear ring 214 and the connecting gear 212 are fixedly connected to the bottom surface inside the mounting frame 206. 12 meshing, the limiting gear ring 213 is fixedly connected inside the connecting gear ring 214, the limiting gear 215 is sleeved on the input end of the first generator body 204, the limiting assembly is set on the connecting shaft 207, the limiting assembly includes an extension frame 216, a fixed block 217, a moving block, an adjusting bolt 220, a counterweight frame 221, a first locking block 222 and a second locking block 223, the extension frame 216 is fixedly connected to the bottom end of the connecting shaft 207, the fixed block 217 is fixedly connected to the top of the extension frame 216, a sliding rod 218 is fixedly connected to one outer surface of the fixed block 217, the moving block is slidably sleeved on the outer surface of the sliding rod 218, the adjusting bolt 220 is rotatably set on the top of the extension frame 216, and one end of the adjusting bolt 220 is rotatably connected to the moving block, the counterweight frame 221 is slidably sleeved on the sliding rod 218. On the outer surface of rod 218, the first locking block 222 and the second locking block 223 are both fixedly connected to the bottom of counterweight frame 221. A limiting spring 219 is slidably sleeved on the outer surface of sliding rod 218. The two ends of the limiting spring 219 are respectively in contact with the moving block and the counterweight frame 221. A limiting opening is opened at the bottom of extension frame 216. The top of counterweight frame 221 slides through the limiting opening. Multiple counterweight blocks 211 are equidistantly inserted inside counterweight frame 221. Fixing bolts slide equidistantly through the bottom of counterweight frame 221. The bottom end of each fixing bolt is threaded to the bottom of the corresponding counterweight block 211. Using a smaller first generator body 204 and a larger second generator body 205, under the drive of a small wind force, the impeller 209, in conjunction with the mounting shaft 208, can drive the connecting shaft 207 to rotate slowly.This allows the connecting shaft 207 to drive the extension frame 216 to rotate slowly. Supported by the moving block and the limiting spring 219, the counterweight frame 221 drives the second locking block 223 to engage with the limiting gear 215, while simultaneously driving the first locking block 222 away from the limiting gear ring 213. This allows the slowly rotating extension frame 216, in conjunction with the counterweight frame 221 and the second locking block 223, to synchronously drive the limiting gear 215 to rotate. The limiting gear 215 then drives the smaller first generator body 204 to rotate, allowing the smaller generator body 204 to operate normally even with lower wind speeds. As the wind speed gradually increases, the impeller 209, in conjunction with the mounting shaft 208, will drive the connecting shaft 207 to rotate rapidly. This rapidly rotating connecting shaft 207 will then drive the extension frame 216 to rotate rapidly. As the rotation speed of the extension frame 216 increases, the counterweight frame 221 and the counterweight block 211 will compress the limiting spring 219 under force, causing the counterweight... The frame 221 can drive the second locking block 223 away from the limiting gear 215, while simultaneously allowing the first locking block 222 to engage with the limiting gear ring 213. This allows the rotating extension frame 216 to rotate the limiting gear ring 213 via the first locking block 222. The limiting gear ring 213, in conjunction with the connecting gear ring 214, connecting gear 212, and side shaft 210, drives the larger second generator body 205, enabling the equipment to generate electricity under various wind conditions. Furthermore, depending on the long-term wind conditions, the adjusting bolt 220 can be rotated to press the adjusting limiting spring 219 via the moving block. Simultaneously, by adding or removing the counterweight 211, the counterweight frame 221 can be adjusted to press the limiting spring 219 with the required force to engage the first locking block 222 with the limiting gear ring 213. This allows for the replacement of different specifications of impellers 209, ensuring that different specifications of impellers 209 can operate normally under various wind conditions.

[0036] The following provides a detailed description of a wind power generation method provided by an embodiment of the present invention, the method of which includes the following steps:

[0037] Step 1, Structural Adjustment: The base frame 101 ensures the equipment is stably positioned in the designated location. Rotating the adjusting worm gear 106, in conjunction with the adjusting worm wheel 104, drives the supporting threaded rod 103 to rotate. This rotating threaded rod 103, under the positional constraints of the limiting block 203 and the limiting groove 107, adjusts the working height of the extension shaft 202. Supported by the extension shaft 202, the top frame 201, mounting frame 206, connecting shaft 207, and mounting shaft 208 support the impeller 209 to a certain height, allowing the impeller 209 to be fully agitated by wind. This allows the equipment to adjust its structure according to the actual operating environment, thereby improving its performance.

[0038] Step 2, Condition Switching: Using the smaller first generator body 204 and the larger second generator body 205, under the influence of a smaller wind force, the impeller 209, in conjunction with the mounting shaft 208, drives the connecting shaft 207 to rotate slowly. This, in turn, causes the connecting shaft 207 to drive the extension frame 216 to rotate slowly. At this time, supported by the moving block and the limiting spring 219, the counterweight frame 221 drives the second locking block 223 to engage with the limiting gear 215, while simultaneously moving the first locking block 222 away from the limiting gear ring 213. This, in turn, causes the slowly rotating extension... The extension frame 216, in conjunction with the counterweight frame 221 and the second locking block 223, can synchronously drive the limiting gear 215 to rotate. This, in turn, allows the limiting gear 215 to drive the smaller first generator body 204 to rotate, enabling the smaller generator body 204 to operate normally even in low wind conditions. As the wind gradually increases, the impeller 209, in conjunction with the mounting shaft 208, will drive the connecting shaft 207 to rotate rapidly. The rapidly rotating connecting shaft 207 will then drive the extension frame 216 to rotate rapidly. As the rotation speed of the extension frame 216 increases, the counterweight frame 216 will rotate, thereby increasing the speed of the first generator body 204. The counterweight frame 221 and the counterweight block 211 can compress the limiting spring 219 under the action of force, so that the counterweight frame 221 can drive the second locking block 223 away from the limiting gear 215, and at the same time, the first locking block 222 can engage with the limiting gear ring 213. In this way, the rotating extension frame 216 can drive the limiting gear ring 213 to rotate through the first locking block 222. Then, the limiting gear ring 213, in conjunction with the connecting gear ring 214, the connecting gear 212 and the side shaft 210, drives the larger second generator body 205 to operate, thereby enabling the equipment to operate under different wind conditions. It can generate electricity under all conditions. At the same time, depending on the wind conditions over a long period of time, by rotating the adjusting bolt 220, the adjusting bolt 220 can compress the adjusting limit spring 219 by moving the moving block. At the same time, by adding or removing the counterweight block 211, the counterweight frame 221 can compress the limit spring 219 to make the first locking block 222 and the limit tooth ring 213 fit together with the required force. In this way, different specifications of impeller 209 can be replaced, so that different specifications of impeller 209 can be used normally under different wind conditions, thereby improving the actual use effect of the equipment.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

S2, Condition Switching: Using a smaller first generator body (204) and a larger second generator body (205), under the influence of a smaller wind force, the impeller (209) and mounting shaft (208) can drive the connecting shaft (207) to rotate slowly, thereby enabling the connecting shaft (207) to drive the extension frame (216) to rotate slowly. At this time, supported by the moving block and the limiting spring (219), the counterweight frame (221) can drive the second locking block (223) to engage with the limiting gear (215), while simultaneously driving the first locking block (222) away from the limiting gear ring (213), thereby enabling the slowly rotating... The extension frame (216), in conjunction with the counterweight frame (221) and the second locking block (223), can synchronously drive the limit gear (215) to rotate, thereby enabling the limit gear (215) to drive the smaller first generator body (204) to rotate, allowing the smaller wind force to drive the smaller first generator body (204) to operate normally. As the wind force gradually increases, during this process, the impeller (209), in conjunction with the mounting shaft (208), will drive the connecting shaft (207) to rotate rapidly. The rapidly rotating connecting shaft (207) will drive the extension frame (216) to rotate rapidly. As the rotation speed of the extension frame (216) increases... This allows the counterweight frame (221) and counterweight block (211) to compress the limiting spring (219) under the action of force, enabling the counterweight frame (221) to drive the second locking block (223) away from the limiting gear (215), while simultaneously enabling the first locking block (222) to engage with the limiting gear ring (213). Consequently, the rotating extension frame (216) can drive the limiting gear ring (213) to rotate through the first locking block (222), which in turn enables the limiting gear ring (213) to work in conjunction with the linkage gear ring (214), linkage gear (212), and side shaft (210) to drive the larger second generator body (205) to operate. This enables the equipment to generate electricity under different wind conditions. Furthermore, based on the long-term wind conditions, the adjustment bolt (220) can be rotated to press the adjustment limit spring (219) by moving the moving block. At the same time, by adding or removing the counterweight (211), the counterweight frame (221) can be adjusted to press the limit spring (219) so that the first locking block (222) and the limit tooth ring (213) fit together with the required force. This allows for the replacement of impellers (209) of different specifications, enabling impellers (209) of different specifications to be used normally under different wind conditions.
