Description

Technical Field

[0001] This invention relates to the technical field of energy storage devices, and in particular to a self-regulating device for wind power generation. Background Technology

[0002] Wind power is one of the most widely used renewable energy technologies, boasting advantages such as abundant resources and small footprint. Depending on the application scenario, wind power equipment can be categorized into portable, residential, commercial, and power station types, with power output and size increasing in that order. A wind power unit consists of a rotor, generator, and tower. The rotor captures wind energy, the generator converts mechanical energy into electrical energy, and the tower supports the rotor and generator while also mitigating the lateral forces of the incoming wind.

[0003] The shortcomings of existing wind power equipment installation technologies: Existing wind power equipment for residential use requires the equipment to be installed on a support pole at a certain height. The installation of the support pole requires a construction team to lay a cement foundation, or the support pole installed on the roof requires screws, which may potentially damage the waterproof layer. Therefore, the infrastructure requirements increase the difficulty of use for users.

[0004] Portable wind power generation equipment can be directly mounted on a tripod for use. However, when wind power generation equipment is directly mounted on a tripod, the tripod and the wind power generation equipment are easily blown over or even blown away by strong crosswinds, making it impossible to use under severe crosswind conditions. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that wind power generation equipment cannot be used under strong cross-flow winds, and to provide a self-regulating device for wind power generation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-regulating device for wind power generation includes a support column, outriggers, support feet, and a counterweight balancer. The counterweight balancer is disposed at the bottom end of the support column. One end of each outrigger is connected to the support column, and the other end of each outrigger is movably connected to the support foot. The number of support feet is equal to the number of outriggers, and at least three support feet are placed at the contact point of a support surface to form a contact surface. When the self-regulating device is not subjected to wind force, the support column is perpendicular to the contact surface, and the center of gravity of the counterweight balancer is projected onto the center of the contact surface. When the self-regulating device is subjected to wind force, the center of gravity of the counterweight balancer changes, causing the outriggers to deform, and the projection of the center of gravity of the counterweight balancer remains within the contact surface, thus keeping the self-regulating device stable.

[0008] In some embodiments of the present invention, the support column is provided with a first adjustment part and a second adjustment part, and the support leg for connecting one end of the support column includes a first connecting end and a second connecting end. The support leg also includes a first elastic damping member. The first connecting end is connected to the first adjustment part through the first elastic damping member, and the second connecting end is connected to the second adjustment part.

[0009] In some embodiments of the present invention, the outrigger further includes a second elastic damping member, a first connecting rod, and a second connecting rod, wherein the first connecting rod and the second connecting rod are movably connected; the first connecting end is located at one end of the first connecting rod, and the second connecting end is located at one end of the second connecting rod; one end of the second elastic damping member is movably connected to the other end of the first connecting rod, and the other end of the second elastic damping member is movably connected to the other end of the second connecting rod.

[0010] In some embodiments of the present invention, the outrigger further includes a third connecting rod and a fourth connecting rod, wherein the second connecting rod and the third connecting rod are parallel to each other; one end of the third connecting rod is movably connected to the other end of the first connecting rod, and the other end of the third connecting rod is movably connected to the fourth connecting rod; one end of the fourth connecting rod is movably connected to the second connecting rod, and the other end of the fourth connecting rod is movably connected to the outrigger.

[0011] In some embodiments of the present invention, the support leg has a hemispherical space and a ball joint that matches the hemispherical space; the other end of the fourth connecting rod is movably connected to the support leg through the ball joint.

[0012] In some embodiments of the present invention, the height of the first connecting end from the contact surface is lower than the height of the first adjusting part from the contact surface; the height of the end of the second connecting rod that is connected to the second elastic damping member from the contact surface is lower than the height of the second adjusting part from the contact surface.

[0013] In some embodiments of the present invention, the first connecting rod, the second connecting rod, and the fourth connecting rod are of the same length, and the length of the third connecting rod is half the length of the first connecting rod.

[0014] In some embodiments of the present invention, half of the first connecting rod is movably connected to half of the second connecting rod, and the third connecting rod is movably connected to half of the fourth connecting rod.

[0015] In some embodiments of the present invention, the distance from the second adjustment part to the center of gravity of the counterweight balancer is one-tenth to one-fifth of the total length of the support column.

[0016] In some embodiments of the present invention, the wind power generation equipment is disposed at the top of the support column; the mounting plate is disposed at the bottom of the support leg.

[0017] The present invention has the following beneficial effects: The self-regulating device proposed in this invention for wind power generation can be used simply by placing it on a contact surface, without the need for laying a foundation or damaging the waterproof layer. As the wind force changes, the self-regulating device will make corresponding adjustments; when subjected to strong crosswinds, the self-regulating device maintains stability through changes in the center of gravity of the counterweight and the deformation of the outriggers, ensuring the normal operation of the wind power generation equipment installed at the top of the support column; and when the wind disappears, the self-regulating device returns to its stable state before being subjected to any force, through changes in the center of gravity of the counterweight and the deformation of the outriggers.

[0018] Meanwhile, the self-adjusting device, through the connecting rods, elastic damping components, and connecting structures of the outriggers, and the ball joints and mounting plates of the outriggers, maintains the stability of the self-adjusting device on the one hand, and has a folding function to facilitate the assembly and transportation of the device on the other.

Therefore, they should not be construed as limitations on the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The following embodiments of the present invention provide a self-regulating device for wind power generation, see reference. Figure 1 , Figure 2 It includes a support column 2, at least three legs 20, feet 13 and a counterweight balancing component 3. The counterweight balancing component 3 is located at the bottom end of the support column 2. One end of the leg 20 is connected to the support column 2, and the other end of the leg 20 is movably connected to the feet 13. The number of feet 13 is equal to the number of legs 20. The feet 13 are placed at the contact point to form a contact surface 14.

[0037] When the self-adjusting device is not subjected to wind, the support column 2 is perpendicular to the contact surface 14 and the center of gravity of the counterweight 3 is projected onto the center of the contact surface 14; when the self-adjusting device is subjected to wind, the center of gravity of the counterweight 3 changes, causing the support leg 20 to deform, so that the center of gravity projection of the self-adjusting device is maintained within the contact surface, thus keeping the self-adjusting device stable; when the wind disappears, the center of gravity of the counterweight 3 returns to the position when it is not subjected to force, and the self-adjusting device returns to the state when it is not subjected to force.

[0038] In a preferred embodiment, the support column 2 is provided with a first adjustment part 4 and a second adjustment part 6; the support leg 20 is used to connect one end of the support column 2, including a first connecting end and a second connecting end, and the support leg also includes a first elastic damping member 5, the first connecting end is connected to the first adjustment part 4 through the first elastic damping member 5, and the second connecting end is connected to the second adjustment part 6; the at least one support leg 20 is used to be placed at the contact point to form a contact surface 14.

[0039] In this embodiment, when the self-adjusting device is subjected to an external force, the first adjusting part 4, the second adjusting part 6, the counterweight balancing member 3, and the first elastic damping member 5 change positions. Specifically, the positions of the first adjusting part 4, the second adjusting part 6, and the counterweight balancing member 3 change, causing the support leg 20 to deform, so that the center of gravity of the self-adjusting device is maintained within the contact surface 14, thus keeping the self-adjusting device stable. When the external force disappears, the first adjusting part 4, the second adjusting part 6, the counterweight balancing member 3, and the first elastic damping member 5 change in the opposite direction, and the self-adjusting device returns to its state when it is not subjected to force.

[0041] In a preferred embodiment, the outrigger 20 further includes a second elastic damping member 9, a first connecting rod 7, and a second connecting rod 8. The first connecting rod 7 and the second connecting rod 8 are movably connected to form a scissor fork structure. The first connecting end is located at the end of the first connecting rod 7 connected to the first elastic damping member 5, and the second connecting end is located at the end of the second connecting rod 8 connected to the second adjusting part 6. One end of the second elastic damping member 9 is movably connected to the other end of the first connecting rod 7, and the other end of the second elastic damping member 9 is movably connected to the other end of the second connecting rod 8. When the self-adjusting device is subjected to an external force, the scissor fork structure changes, and the distance between the first connecting end and the second connecting end changes. When the external force disappears, under the action of the first elastic damping member 5 and the second elastic damping member 9, the distance between the first connecting end and the second connecting end changes in the opposite direction, and the self-adjusting device returns to the state when it is not subjected to force.

[0042] In order to form a self-stabilizing structure, the height relationship between the first adjusting part 4, the second adjusting part 6 and the first connecting end and the second connecting rod 8 should meet the following requirements: the height of the first connecting end from the contact surface 14 is lower than the height of the first adjusting part 4 from the contact surface 14; the height of the end of the second connecting rod 8 that is used to connect with the second elastic damping member 9 from the contact surface 14 is lower than the height of the second adjusting part 6 from the contact surface 14.

[0043] In a preferred embodiment, the outrigger further includes a third connecting rod 10 and a fourth connecting rod 11, wherein the second connecting rod 8 and the third connecting rod 10 are parallel to each other; one end of the third connecting rod 10 is movably connected to the other end of the first connecting rod 7, and the other end of the third connecting rod 10 is movably connected to the fourth connecting rod 11; one end of the fourth connecting rod 11 is movably connected to the second connecting rod 8, and the other end of the fourth connecting rod 11 is movably connected to the outrigger 13 through the ball joint 12.

[0047] In a preferred embodiment, a wind power generation device 1 is provided at the top of the support column 2. The wind power generation device 1 includes a wind turbine, a generator and its tower. An mounting plate is provided at the bottom of the support leg 13. The mounting plate includes a guide rail and a groove for the support leg to slide.

[0048] In a preferred embodiment, the counterweight is a sphere, and the sphere is made of one of the following materials: metal alloy, inorganic non-metallic material, and polymer material.

[0049] The specific implementation methods of the present invention will be further explained below with reference to Example 1.

[0050] Example 1

[0051] In this embodiment, a wind power generation device is installed on the top of the self-regulating device.

[0052] This embodiment proposes a self-regulating device equipped with wind power generation equipment, the main structure of which is as follows: Figure 3a and Figure 3b As shown. In this embodiment, the support leg 13 is a square block with a certain weight. The upper surface has a hemispherical hollow space. The ball joint 12 is used in conjunction with the hemispherical space of the support leg 13. The number of the first elastic damping member 5, the second elastic damping member 9, the support leg 20, the support leg 13, and the ball joint 12 are all 3.

[0053] In a specific embodiment, the center of the first adjusting part 4 is a cylindrical ring that can be fitted onto the support column 2. The ring has threaded holes for fastening with the first bolt 101. After the height of the first adjusting part 4 is adjusted on the support column 2, it is fastened with the first bolt 101 to correspond to the threaded holes on the support column, thus fixing the first adjusting part 4. Circumferentially, there are three cylindrical joints distributed at 120 degrees, which can be hinged to the first elastic damping 5. A partial magnification is shown below. Figure 6a As shown.

[0054] In this embodiment, the outrigger 20 includes a first connecting rod 7, a second connecting rod 8, a third connecting rod 10, a fourth connecting rod 11, a first elastic damping element 5, and a second elastic damping element 9. Specifically, the connection between one end of the second elastic damping element 9 and the first connecting rod 7 and the third connecting rod 10 is the first connection structure, wherein the third connecting rod 10 is located between the first connecting rod 7 and the second elastic damping element 9; the connection between the other end of the second elastic damping element 9 and the second connecting rod 8 and the fourth connecting rod 11 is the second connection structure, wherein the second connecting rod 8 is located between the second elastic damping element 9 and the fourth connecting rod 11; the end of the first connecting rod 7 used to connect with the first elastic damping element 5 is the first connection end, connected by a pin 106, the specific connection method being as follows. Figure 6b As shown, the end of the second connecting rod 8 used to connect with the second adjusting part 6 is the second connecting end.

[0055] In this embodiment, the first connecting rod 7, the second connecting rod 8, and the fourth connecting rod 11 of the support leg 20 are of equal length, and the length of the third connecting rod 10 is half the length of any one of the first three rods. The support leg 20 is a parallel linkage mechanism, with the second connecting rod 8 and the third connecting rod 10 of the support leg 20 being absolutely parallel. The second elastic damping member 9 spans across the diagonal line. The first connecting rod 7 and the second connecting rod 8 form a scissor fork structure, and the first connecting rod 7 and the second connecting rod 8 are connected at their respective midpoints by a pin 106, specifically at the midpoint of the first connecting rod 7 and the second connecting rod 8. The third connecting rod 10 is connected to the center point of the fourth connecting rod 11 by a pin, specifically at the midpoint of the fourth connecting rod 11.

[0056] In this embodiment, there are three outriggers 20, and correspondingly, there are three first elastic damping elements 5, three foot 13, and three ball joints 12.

[0057] In this embodiment, the interconnection of the components is as follows: the uppermost wind turbine 1 is installed at the top of the support column 2. The wind turbine 1 can be connected to the top of the support column 2 via a flange 104 and flange bolts 105, as shown in the following connection method. Figure 6c As shown, the first adjusting part 4 is fastened to the support column 2 with the first bolt 101. The first elastic damping element 5 is installed in the circumferential direction of the first adjusting part 4 in the form of a hinge. The other end of the first elastic damping element 5 is connected to the first connecting rod 7 of the support leg 20 with a pin 106. That is, the other end of the first elastic damping element 5 is connected to the first connecting end. The bottom end of the fourth connecting rod 11 of the support leg 20 is embedded in the support foot 13 through the ball joint 12. The ball joint 12 can move in the support foot 13, thereby driving the support leg 20 to move within a certain range. The support foot 13 is placed flat on the contact surface 14 and can be used without fixing. In addition, the lower end of the first adjusting part 4 on the support column 2 is fastened to the second adjusting part 6 with the second bolt 102. The second adjusting part 6 is connected to the second connecting rod 8 of the support leg 20 in the circumferential direction in the form of a hinge. That is, the second adjusting part 6 is connected to the second connecting end. The bottom end of the support column 2 is inserted into the counterweight balance part 3 and fixed with the nut 103. The distance between the first adjustment part 4 and the second adjustment part 6 is determined by the angle of each connecting rod; the distance from the second adjustment part 6 to the center of the counterweight balance part 3 is 1 / 10 to 1 / 5 of the total length of the support column 2.

[0058] To form a self-stabilizing structure, the necessary positional relationships of the components are as follows: the first adjustment part 4 must be higher than the other end of the first elastic damping member 5 connected to it, that is, higher than the first connection end; the second adjustment part 6 must be higher than the other end of the second connecting rod 8 connected to it. Only by combining these can an upward thrust be generated to counteract gravity.

[0059] The operating principle of the self-regulating device applied to wind power generation in this embodiment is as follows: (1) In the original state, the three legs 20 of the self-regulating device support the pillar 2 with the same degree of opening and closing, such as Figure 3a As shown; (2) When the self-regulating device or wind power generation equipment 1 is subjected to wind force, if a small lateral wind blows, the wind power generation equipment 1 and the support column 2 will swing slightly. At this time, the three first elastic damping elements 5 and the three second elastic damping elements 9 will maintain balance and absorb vibration energy; (3) When the self-regulating device or wind power generation equipment 1 is subjected to stronger wind force, if a violent lateral wind blows, the wind power generation equipment 1 and the support column 2 will tilt significantly in accordance with the wind direction. With the second regulating part 6 as the fulcrum, the parallel linkage structure and scissor fork structure of the support leg will deform. The distance between the first and second connecting ends changes, and the first elastic damping element 5 and the second elastic damping element 9 also deform. The first adjusting part 4 pushes the first connecting rod 7 at the far end of the wind direction to extend the outrigger 20. The sliding thrust of one outrigger 13 in the wind direction is greater than that of the other two outriggers. When the thrust of this outrigger is greater than the friction of the contact surface 14, it will slide forward on the contact surface 14, causing the contact surface 14 to expand. However, the center of gravity is still maintained within the projection plane of the mechanism on the contact surface 14, preventing the entire self-adjusting device used in wind power generation from tipping over. Figure 4a , Figure 4b As shown, the arrow indicates the direction of the wind force on the self-adjusting device; when the thrust is less than the ground friction, the support leg 13 will remain stationary, but the reaction force from the contact surface 14 will also make the self-adjusting device more stable; (4) In theory, the force on all wind directions can be adjusted according to the same principle, only the extension degree of the support legs in different directions is different, and they are coordinated with each other; (5) When the crosswind stops, the first elastic damping element 5, the second elastic damping element 9 and the counterweight balance element 3 work together to restore the self-adjusting device used in wind power generation to its original state, such as Figure 3a and Figure 3b As shown.

[0060] Preferably, the self-adjusting device for wind power generation in this embodiment can be folded according to the following steps: First, loosen the first bolt 101 and the second bolt 102 that fix the first adjusting part 4 and the second adjusting part 6; second, pull out the pin 106 that fixes the first elastic damping member 5 and the first connecting rod 7; finally, move the first elastic damping member 5 and the support leg 20 closer to the support column 2. Figure 5 As shown, the folded self-regulating device used in wind power generation is easy to store and transport.

[0061] When installing a self-regulating device for wind power generation in its folded state, follow these steps:

[0062] S1. After adjusting the positions of the first adjusting part 4 and the second adjusting part 6, tighten the first bolt 101 and the second bolt 102 in sequence.

[0063] S2. Spread the first elastic damping element 5 and the support leg 20 outwards;

[0064] S3. Insert pin 106 to fix the first elastic damping member 5 and the first connecting rod 7;

[0065] S4. The self-adjusting device is placed upright on the contact surface 14, and the self-adjusting device will naturally open at this time.

[0066] S5. Install the wind power generation equipment 1 on the top flange 104 using flange bolts 105.

[0067] The self-adjusting device for wind power generation proposed in this embodiment utilizes the parallel linkage structure of the outriggers, the first adjustment part 4, the second adjustment part 6, and the counterweight balance part 3 to adjust the center of gravity and dampen and absorb vibration energy. It has the advantages of being ready to use immediately, self-adjusting the center of gravity, and being foldable. Using the self-adjusting device for wind power generation in this embodiment, the wind turbine of the wind power generation equipment can be supported at a height equivalent to 2 to 3 times the width of the chassis (the diameter of the circle formed by the three outriggers 13) without tipping over.

[0068] Compared to simply using a tripod, the self-regulating device for wind power generation in this embodiment of the invention has the following advantages:

[0069] 1. The flexible and elastic outriggers can help to dissipate external forces and adjust the center of gravity.

[0070] 2. Two adjustment units, the first adjustment unit 4 and the second adjustment unit 6, are used for self-adjustment of posture to realize leg movements.

[0071] 3. The counterweight balancer 3 installed at the bottom of the support column is used to stabilize the center of gravity.

[0072] 4. The first elastic damping element 5 can enable the self-adjusting device to return to its original state after unloading. When the first elastic damping element 5 is combined with the second elastic damping element 9 and the counterweight balance element 3, the self-adjusting device can return to its original state faster and better.

[0073] 5. Convenient and foldable; simply unscrew the bolts on the first adjustment part 4 and the second adjustment part 6 to complete the folding process.

[0074] 6. Passive balancing method: The application of counterweight balancing component 3, first elastic damping component 5, and second elastic damping component 9 enables the self-regulating device used in wind power generation to have self-balancing internal power, thus eliminating the need for an external power source.
