Description
Technical Field
[0001] The invention relates to the application field of vertical axis wind turbines, in particular to a new energy wind power generation and energy storage device. Background Art
[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. Wind power generation is very environmentally friendly and has huge wind energy reserves. The equipment that uses wind power to generate electricity is called a wind turbine, and wind turbines mainly include asynchronous, synchronous, horizontal axis and vertical axis wind turbines.
[0003] The working principle of vertical axis wind turbine is based on the interaction between wind energy and blades. When wind passes through the blades of the generator, each blade is hit by the wind at a different angle, thereby generating a torque around the central axis. The rotation of the blades is transmitted to the generator through the shaft, and the generator converts mechanical energy into electrical energy and stores it.
[0004] Compared with horizontal-axis wind turbines, vertical-axis wind turbines often require a higher starting wind speed to start and achieve efficient operation. Vertical-axis wind turbines are greatly affected by changes in wind speed and direction and are prone to power fluctuations. In addition, the rotor of a vertical-axis wind turbine is usually perpendicular to the wind direction, which causes the rotor center of gravity to be unstable and prone to swinging and shaking, thereby affecting the operating stability of the generator, especially in strong wind weather, which can easily cause rotor deformation and blade damage. Summary of the invention

[0019] By adopting the above technical solution, by setting a first bracket, a first metal rod, a first gear and a second bevel gear, the rotating drum drives the first gear to rotate through the face gear, so that the second bevel gear rotates accordingly, and by changing the gear ratio, the second bevel gear can increase the rotation speed of the forward and reverse threaded rod when it is engaged with the first bevel gear.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0038] The following describes an embodiment of the present invention based on its overall structure.

The rotation speed change of the forward and reverse threaded rod 4 causes the two groups of threaded sleeves 5 to move away from each other, thereby realizing the folding and contraction of the blades 7. The forward and reverse threaded rod 4 can use wind energy to change its rotation speed under different wind speeds, thereby realizing the speed difference between the drum 2 and the forward and reverse threaded rod 4, that is, the rotation speed of the forward and reverse threaded rod 4 is greater than that of the drum 2, the forward and reverse threaded rod 4 and the drum 2 rotate synchronously, and the rotation speed of the forward and reverse threaded rod 4 is less than that of the drum 2. By setting a wind speed sensor to detect the wind speed of strong winds outside, when the wind speed exceeds the safety value, the rotation speed of the forward and reverse threaded rod 4 begins to decrease compared with the drum 2, thereby driving the two groups of threaded sleeves 5 to move away from each other, and then the blades 7 are folded inward to improve the stability of the generator, while reducing wind resistance and actively reducing the rotation speed of the drum 2.
[0040] See also Figure 3 The rotating drum 2 is hollow, and a plurality of strip grooves matching the threaded sleeve 5 are arranged on the side of the rotating drum 2, and the rotating drum 2 and the threaded sleeve 5 are slidably connected. By arranging the rotating drum 2 to be hollow, the threaded sleeve 5 can slide inside the rotating drum 2.

Multiple groups of paddle blades 7 are evenly arranged, and the multiple groups of paddle blades 7 and connecting rods 6 are movably installed. By arranging multiple groups of connecting rods 6 on the sides of the two groups of threaded sleeves 5, multiple groups of paddle blades 7 can be movably installed, and the multiple groups of paddle blades 7 can better drive the rotating drum 2 to rotate.
[0042] See also Figure 6The transmission mechanism 28 includes an electric telescopic component 11 installed on the top of the mounting plate 10, and the top of the electric telescopic component 11 is rotatably connected to the sleeve 12, and the outside of the sleeve 12 is installed with a first bevel gear 13, and the top of the first bevel gear 13 is installed with a spring 14, and the top of the spring 14 is installed with a second friction plate 15, and the second friction plate 15 and the inside of the sleeve 12 are installed with a limiting block 16.

[0043] See also Figure 8 The transmission mechanism 28 includes a fixed rod 9 installed at the bottom of the forward and reverse threaded rod 4, and the fixed rod 9 movably penetrates into the interior of the sleeve 12 and the second friction plate 15, and a limiting groove 17 matching the limiting block 16 is provided on the outside of the fixed rod 9. By installing the fixed rod 9 at the bottom of the forward and reverse threaded rod 4 and providing the limiting groove 17, the sleeve 12 and the second friction plate 15 can slide outside the fixed rod 9, and the fixed rod 9 can drive the sleeve 12 and the second friction plate 15 to rotate.
[0044] See also Figure 6 The transmission mechanism 28 includes a first friction plate 8 installed on the top of the mounting plate 10, and the first friction plate 8 is located above the second friction plate 15. The first friction plate 8 is sleeved on the outside of the fixed rod 9, and the first friction plate 8 and the fixed rod 9 are not in contact. By setting the first friction plate 8, the rotation speed of the forward and reverse threaded rod 4 can be reduced when the second friction plate 15 is in contact with the first friction plate 8.
[0045] See also Figure 6 The transmission mechanism 28 includes a first bracket 18 installed on the top of the mounting plate 10, and the side of the first bracket 18 is rotatably connected to the first metal rod 19, and the first gear 20 and the second bevel gear 21 are installed on the outside of the first metal rod 19. The first gear 20 and the face gear 3 are meshed for transmission. By setting the first bracket 18, the first metal rod 19, the first gear 20 and the second bevel gear 21, the rotating drum 2 drives the first gear 20 to rotate through the face gear 3, so that the second bevel gear 21 rotates accordingly.

[0046] See also Figure 6 The first friction plate 8 and the second friction plate 15 are made of semi-metallic friction material. The first friction plate 8 and the second friction plate 15 made of semi-metallic material have good heat resistance and thermal conductivity, and are suitable for heavy-load operating conditions.
[0047] See also Figure 1 A wind speed sensor is arranged on the side of the base 1 for detecting the size of the external wind speed. By arranging a wind speed sensor on the side of the base 1, for example, a three-cup wind speed sensor can measure the external wind speed, and then use the wind speed sensor measurement data as a signal to control the operation of the electric telescopic component 11 through the PCL program to realize the folding, contraction and opening of the blades 7.
[0048] The working principle of the present invention is as follows: external wind force drives the rotating drum 2, the face gear 3, the forward and reverse threaded rods 4, the threaded sleeve 5, the connecting rod 6 and the blades 7 to rotate rapidly, and then the face gear 3 meshes with the second gear 24 and drives it to rotate, the second gear 24 drives the second metal rod 23 to rotate, the second metal rod 23 drives the third bevel gear 25 to rotate, and the third bevel gear 25 and the fourth bevel gear 27 mesh with each other, so that the fourth bevel gear 27 drives the input shaft 26 to rotate, and the bottom of the input shaft 26 is connected to the generator set of the equipment, thereby realizing the conversion of wind energy into mechanical energy, and then converting mechanical energy into electrical energy for storage.
[0049] When the external wind speed increases, the wind speed sensor (for example, a three-cup anemometer, which belongs to the prior art and will not be described in detail here) detects that the average wind speed within one hour of the external strong wind exceeds the safety value, for example, when the wind speed exceeds the safety value of 25 meters per second, the rotating drum 2, the face gear 3, the positive and negative threaded rods 4, the threaded sleeve 5, the connecting rod 6 and the blade 7 are in a state of rapid rotation, and the positive and negative threaded rods 4 drive the fixed rod 9 to rotate, and the sleeve 12, the first bevel gear 13, the spring 14 and the second friction plate 15 sleeved on the outside of the fixed rod 9 also rotate synchronously with the fixed rod 9 under the limiting action of the limit block 16 and the limit groove 17, and then the electric telescopic component 11 uses the power supply inside the equipment to start and push the sleeve 12 up, and then the sleeve 12 drives the first bevel gear 13, the spring 14 and the second friction plate 15 to rotate synchronously with the fixed rod 9. The spring 14 and the second friction plate 15 rise, and the second friction plate 15 will fit and contact with the first friction plate 8. Under the action of the spring 14, the second friction plate 15 and the first friction plate 8 are slightly fitted, so that the friction force generated by the fitting can reduce the rotation speed of the second friction plate 15. Similarly, the sleeve 12, the first bevel gear 13, the spring 14, the second friction plate 15 and the fixed rod 9, and the forward and reverse threaded rod 4 begin to decelerate, and then the rotation speed of the forward and reverse threaded rod 4 is less than the rotation speed of the rotating drum 2, and the rotation speed of the rotating drum 2 and the threaded sleeve 5 is the same, so that the forward and reverse threaded rod 4 and the threaded sleeve 5 are no longer synchronously rotated but relatively rotated. By using the screw principle, the two groups of threaded sleeves 5 are moved away from each other, thereby pushing the connecting rod 6 to expand, so that the multiple groups of blades 7 are close to the rotating drum 2, that is, the multiple groups of blades 7 are contracted and folded.
[0050] When the multiple groups of blades 7 are folded and retracted to the appropriate position, the electric telescopic assembly 11 is started to drive the sleeve 12, the first bevel gear 13, the spring 14 and the second friction plate 15 to descend, so that the first friction plate 8 and the second friction plate 15 are separated, and the second friction plate 15 is no longer affected by the friction force, and then the sleeve 12, the first bevel gear 13, the spring 14, the second friction plate 15, the fixed rod 9 and the forward and reverse threaded rods 4 gradually resume synchronous rotation with the drum 2, and the blades 7 are still opened to a certain extent to continue working. At the same time, at this time, the influence of wind force on the folding and contraction of the blades 7 will be reduced, making the operation of the equipment more stable, and the wind resistance of the equipment is reduced, so that the rotation speed of the blades 7 also begins to slowly decrease.
[0051] The folded state of the multiple sets of blades 7 will last for two hours. During the two hours, the wind speed sensor will detect the average wind speed outside. When the average wind speed is still greater than the safety value, the multiple sets of blades 7 remain in the folded state. When the average wind speed is less than the safety value, the electric telescopic assembly 11 is started to drive the sleeve 12, the first bevel gear 13, the spring 14 and the second friction plate 15 to descend, and the rotating drum 2 drives the face gear 3 to rotate, the face gear 3 drives the first gear 20 to rotate, the first gear 20 drives the first metal rod 19 and the second bevel gear 21 to rotate, and the sleeve 12 It descends and meshes with the second bevel gear 21. By changing the gear ratio, the sleeve 12 is accelerated to drive the fixed rod 9 and the forward and reverse threaded rod 4 to rotate, and then the rotation speed of the forward and reverse threaded rod 4 is greater than the rotation speed of the rotating drum 2. According to the above, the two groups of threaded sleeves 5 are close to each other, and then the connecting rod 6 is driven to contract, so that the multiple groups of blades 7 are expanded outward. When the blades 7 expand to a certain extent, the electric telescopic assembly 11 is started in time to separate the sleeve 12 and the second bevel gear 21, and then the rotating drum 2 and the forward and reverse threaded rod 4 resume synchronous rotation, and the blades 7 are in an open state.
