[0002] Wind power generation is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries are paying more attention to wind power generation. As a clean and renewable energy source, wind energy is increasingly valued by countries around the world. Wind power generation converts the kinetic energy of wind into mechanical kinetic energy, and then converts mechanical energy into electrical kinetic energy. This is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to drive the wind turbine generator to generate electricity.

Detailed implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , a safe and stable wind power generation device, including a counterweight base plate 1, a connecting seat 2 is placed on the upper surface of the counterweight base plate 1, a connecting disc 3 is fixedly connected to the upper surface of the connecting seat 2, a servo motor 4 is fixedly installed on the upper surface of the connecting disc 3. The servo motor 4 refers to an engine that controls the operation of mechanical components in the servo system and is an auxiliary motor indirect speed change device. The servo motor 4 can control the speed and has accurate position accuracy. It can convert the voltage signal into torque and rotational speed to drive the control object. Compared with a single-phase asynchronous motor, the servo motor 4 has three significant characteristics: large starting torque, a wider operating range, and no self-rotation phenomenon. The output end of the servo motor 4 is fixedly installed with a threaded lifting lead screw 7, the outer surface of the threaded lifting lead screw 7 is threadedly connected with a threaded lifting nut 8, a protective cover 20 is fixedly connected to the upper surface of the connecting disc 3, a sealing plate 5 is fixedly connected to the upper surface of the protective cover 20, and a fixed sliding cylinder 10 is fixedly connected to the upper surface of the sealing plate 5.

[0027] Two strip-shaped holes 11 are formed in the outer surface of the fixed sliding cylinder 10. The inner walls of the two strip-shaped holes 11 are both slidably connected with lifting support plates 9. One side surfaces of the two lifting support plates 9 close to each other are fixedly connected with the outer surface of the threaded lifting screw cylinder 8. The upper surfaces of the two lifting support plates 9 are fixedly connected together with a support top seat 12. A support top plate 13 is fixedly installed on the upper surface of the support top seat 12. A plurality of vertical-axis wind turbines 14 are fixedly installed on the upper surface of the support top plate 13. The vertical-axis wind turbines 14 do not need to face the wind when the wind direction changes, which is a great advantage compared with the horizontal-axis wind turbines in this regard. It not only simplifies the structural design, but also reduces the gyroscopic force when the wind turbine faces the wind. A flashing light 15 is fixedly installed on the upper surface of each vertical-axis wind turbine 14. The bottom surface of the counterweight bottom plate 1 is fixedly connected with a concrete counterweight base 22.

[0028] In a preferred embodiment, a positioning block 24 is fixedly connected to the upper surface of the counterweight bottom plate 1. A positioning groove 23 is formed in the bottom surface of the connecting seat 2. The top end of the positioning block 24 extends into the interior of the positioning groove 23. Two threaded plates 26 are fixedly connected to the upper surface of the counterweight bottom plate 1. The inner walls of the two threaded plates 26 are both threadedly connected with fixing screws 27. Threaded grooves 25 are formed in the left and right side surfaces of the connecting seat 2. The outer surfaces of the two fixing screws 27 are respectively adapted to the inner walls of the two threaded grooves 25. Through the cooperation of the positioning block 24 and the positioning groove 23, positioning and guiding can be carried out between the connecting seat 2 and the concrete counterweight base 22. Through the cooperation of the threaded plates 26, the fixing screws 27 and the threaded grooves 25, the connecting seat 2 and the concrete counterweight base 22 can be quickly connected and fixed, and it is convenient for subsequent disassembly and movement.

[0029] In a preferred embodiment, a bearing 6 is fixedly embedded in the bottom surface of the sealing plate 5. The inner ring of the bearing 6 is fixedly connected with the outer surface of the threaded lifting screw rod 7. A detection rod 16 is fixedly installed on the upper surface of the support top plate 13. An anemometer sensor 17 is fixedly installed at the top end of the detection rod 16. The sensing element of the anemometer sensor 17 is a three-cup wind assembly, which consists of three carbon fiber wind cups and a cup holder. The converter is a multi-tooth rotating cup and a slit optical coupler. When the wind cups rotate under the action of horizontal wind force, through the rotation of the live-axis rotating cup in the slit optical coupler, a signal of frequency is output. Through the setting of the bearing 6, the threaded lifting screw rod 7 can operate more stably. By using the detection rod 16 and the anemometer sensor 17, the function of sensing the wind speed is achieved, and the wind speed data will be converted into an electrical signal for transmission.

[0030] In a preferred embodiment, two limit sliding seats 19 are fixedly connected to the outer surface of the fixed sliding cylinder 10, and two limit sliding plates 18 are fixedly connected to the bottom surface of the support top seat 12. One end of the two limit sliding plates 18 close to each other extends into the two limit sliding seats 19 respectively, and the outer surfaces of the two limit sliding plates 18 are respectively connected to the inner walls of the two limit sliding seats 19. Through the cooperation of the limit sliding seats 19 and the limit sliding plates 18, the support top seat 12 can move up and down more stably, and the problem of slipping when the support top seat 12 moves upward can be avoided.

[0031] In a preferred embodiment, a vertical plate 30 is fixedly installed on the front surface of the connecting seat 2, and a controller 21 is fixedly installed on the front surface of the vertical plate 30. The controller 21 refers to a master device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking, and reverse of the servo motor 4. The controller 21 is composed of a program counter, an instruction register, an instruction decoder, a timing generator, and an operator, that is, it completes the operation of coordinating and commanding the entire computer system. Two handles 29 are fixedly connected to the upper surface of the connecting seat 2, and grooves 28 are formed on the left and right sides of the concrete counterweight base 22. Through the setting of the vertical plate 30 and the controller 21, the operation of the device will be controlled. By using the setting of the handles 29, it is convenient to install and hoist the device. Through the setting of the grooves 28, it is convenient to move the concrete counterweight base 22.

[0032] Working principle: First, take the device and the concrete counterweight base 22, and place the concrete counterweight base 22 on a flat ground. Then, make the positioning groove 23 above the positioning block 24. Then, place the connecting seat 2 above the counterweight bottom plate 1, and insert the positioning block 24 into the positioning groove 23. Then, rotate the fixing screw 27, and the fixing screw 27 will rotate inside the threaded plate 26 until the fixing screw 27 rotates into the threaded groove 25, and then the connecting seat 2 can be firmly installed and fixed above the counterweight bottom plate 1;

[0033] Next, start the servo motor 4 to operate, which can drive the threaded lifting lead screw 7 and the threaded lifting barrel 8 to perform threaded engagement. This will cause the threaded lifting barrel 8 to drive the lifting support plate 9 and the supporting top seat 12 to move upward. At the same time, it will also drive the multiple vertical-axis wind turbines 14 above the supporting top plate 13 to rise. Then, through the operation of the multiple vertical-axis wind turbines 14, wind power generation work will be carried out simultaneously, thereby increasing the wind power generation performance. When strong wind weather occurs, the wind speed sensor 17 can sense the wind speed signal and transmit it to the controller 21 for processing. The controller 21 can start the servo motor 4 to rotate in the reverse direction, which will drive the lifting support plate 9, the supporting top plate 13, and the multiple vertical-axis wind turbines 14 to descend. Thus, the overall wind resistance of the vertical-axis wind turbines 14 can be reduced, ensuring the stability during wind power generation.
