Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of generator, and particularly relates to a torsion type wind-solar complementary generator. BACKGROUND

[0002] Due to the "oil crisis", the problem of energy shortage appears, people realize the instability and finiteness of conventional mineral energy supply, so seeking clean renewable energy becomes an important issue in the modern world. Wind energy and solar energy as renewable and pollution-free natural energy have attracted people's attention.

[0003] The principle of wind power generation is to use wind to drive windmill blades to rotate, and then to increase the rotating speed through a speed increaser to promote the generator to generate electricity. As shown in the figure, according to the current wind turbine technology, about three meters per second of wind speed (the degree of breeze) can start to generate electricity. Wind power generation is forming a hot trend in the world, because wind power generation has no fuel problem, and will not produce radiation or air pollution. As a clean renewable energy, wind energy is increasingly valued by countries around the world. Its reserves are huge. Figure 1

[0004] Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. It mainly consists of solar panels (components), controllers and inverters, and the main components are composed of electronic components. Solar cells are connected in series and encapsulated to form large-area solar cell modules, and then combined with power controllers and other components to form a photovoltaic power generation device.

[0005] However, due to the fact that the sun is sufficient and the wind is insufficient when it is sunny, and the sun is insufficient and the wind is sufficient when it is cloudy, the wind turbine and the photovoltaic generator cannot simultaneously absorb wind energy and solar energy maximization.

[0006] ​A vertical axis wind turbine set with lift and drag composite for wind-solar integrated power generation system is disclosed in Chinese Patent Publication No. CN113217272A on August 6, 2021, which comprises an H-type vertical axis lift-type wind turbine (1) and a spiral blade S-type vertical axis drag-type wind turbine (2) combined to form an H-S lift and drag composite telescopic vertical axis wind turbine set. The wind turbine blades of the S-type vertical axis drag-type wind turbine (2) are fixedly installed on the rotating shaft, and the blade length of the H-type vertical axis lift-type wind turbine (1) is fixed. A transverse support (3) is provided in the middle, and a telescopic adjusting device (4) is provided on the transverse support (3), so as to obtain a wind sweeping area with an adjustable area of 60%-100%. By effectively combining the advantages of lift-type and drag-type wind turbines, the wind turbine can be started at a small wind speed, and the wind turbine efficiency remains high at a high wind speed. The wind turbine start is not limited by wind direction, the starting wind speed is small, and the wind energy capture efficiency is high at high wind speed. However, this patent only improves the wind power generation efficiency, but does not make good use of photovoltaic power generation. SUMMARY

[0033] Embodiment

[0034] As Figure 1As shown, this embodiment provides a torsion-type wind-solar hybrid generator, including a vertically mounted mast 1. A rotating shaft 2 is coaxially mounted on the mast 1 (a generator set is installed inside the mast 1, and the rotation of the rotating shaft 2 drives the generator set to generate electricity). A first slip ring 3 and a second slip ring 4 are sleeved on the outside of the rotating shaft 2. Three vertical blades 5 are evenly arranged circumferentially along the outer edge of the rotating shaft 2 (the number of blades 5 can be adjusted according to actual conditions). A photovoltaic thin film 6 is applied to the outer surface of the blades 5. The blades 5 are connected to the first slip ring 3 and the second slip ring 4 respectively through a first sliding rod 7 and a second sliding rod 8. The two ends of the first sliding rod 7 are hinged to the blades 5 and the first slip ring 3 respectively. One end of the second sliding rod 8 is fixedly connected to the second slip ring 4, and the other end is slidably connected to the blades 5. A first drive mechanism is mounted on the rotating shaft 2 to drive the first slip ring 3 to rotate, causing the blades 5 to twist. A second drive mechanism is also provided on the rotating shaft 2 to drive the second slip ring 4 to rise and fall, adjusting the pitch angle of the blades 5. The generator also includes a controller, which is connected to the first drive mechanism and the second drive mechanism respectively.

[0035] In this embodiment, by applying a photovoltaic thin film 6 to the outer surface of the blade 5, wind energy and solar energy can be converted into electrical energy simultaneously using the blade 5, eliminating the need for separate solar photovoltaic panels and saving installation space. In addition, when the wind is strong on cloudy days, the invention can drive the first slip ring 3 to rotate through the first drive mechanism, causing the blade 5 to twist and making the blade 5 streamlined, which can collect wind energy from all directions and improve the utilization rate of wind energy. When the sunlight is sufficient on sunny days, the second slip ring 4 can be driven to rise through the second drive mechanism, increasing the pitch angle of the blade 5, so that the photovoltaic thin film 6 on the blade 5 can absorb light energy to the maximum extent, thereby improving the utilization rate of light energy.

[0036] Specifically, the first slip ring 3 is mounted on the outer wall of the rotating shaft 2 via a ball bearing. The ball bearing reduces rotational friction and ensures that the first slip ring 3 rotates on the rotating shaft 2 without moving up or down.

[0037] Furthermore, such as Figure 5 As shown, the first driving mechanism includes a first rotary motor 9, a driving gear 10, and a driven gear 11. The driving gear 10 is installed at the output end of the first rotary motor 9, and the driven gear 11 is fixed to the lower end face of the first slip ring 3 by welding. The driven gear 11 meshes with the driving gear 10. The first rotary motor 9 drives the driving gear 10 to rotate, which in turn drives the driven gear 11 to rotate, thereby driving the first slip ring 3 to rotate, thus realizing the torsion of the blade 5.

[0038] Specifically, the second driving mechanism comprises a linear motor 12 and a second rotary motor 13; the linear motor 12 is mounted on the rotating shaft 2 and used to drive the second sliding ring 4 to ascend and descend along the rotating shaft 2 in the axial direction; the second rotary motor 13 is mounted on the hinge part of the first sliding ring 3 and the first sliding rod 7 and used to drive the first sliding rod 7 to rotate.

[0039] Further, the outer wall of the rotating shaft 2 is provided with a first sliding groove 14 in the axial direction, and the inner wall of the second sliding ring 4 is provided with a first sliding block matched with the first sliding groove 14; by arranging the first sliding groove 14 and the first sliding block, the second sliding ring 4 can be constrained to prevent it from rotating during the ascending and descending process, so that the second sliding ring 4 only ascends and descends without rotating.

[0040] Specifically, the inner side of the blade 5 is provided with a second sliding groove 15, the second sliding groove 15 is slidably embedded with a second sliding block 16, and the end of the second sliding rod 8 away from the second sliding ring 4 is hingedly connected with the second sliding block 16. By driving the second sliding ring 4 to ascend by the linear motor 12, the second sliding block 16 is driven to ascend along the second sliding groove 15, and at the same time, the first sliding rod 7 is driven to rotate by the second rotary motor 13, so that the first sliding rod 7 rotates counterclockwise around the hinge part, and the top end of the blade 5 is driven to approach the rotating shaft 2. During the ascending process of the second sliding ring 4, the bottom end of the blade 5 is away from the rotating shaft 2, and the blade 5 is approximately opened like an "umbrella".

[0041] Preferably, the machine rod 1 is provided with an illuminance sensor and a wind speed sensor, the illuminance sensor and the wind speed sensor are respectively connected with a controller, and the controller controls the first driving mechanism or the second driving mechanism to act according to the data detected by the wind speed sensor and the illuminance sensor.

[0042] Preferably, the controller calculates the photovoltaic power P1 according to the illuminance value detected by the illuminance sensor, calculates the wind power P2 according to the wind speed value detected by the wind speed sensor, if the difference between P1 and P2 is less than a preset value, the first driving mechanism and the second driving mechanism do not act, and the generator is in an initial state; if the difference between P1 and P2 is greater than or equal to the preset value, and P1 is greater than P2, the controller controls the second driving mechanism to act, drives the second sliding ring 4 to ascend, and the pitch angle of the blade 5 increases, so that the blade 5 is in an "umbrella" structure, and the generator is in a photovoltaic power generation state; if the difference between P1 and P2 is greater than or equal to the preset value, and P1 is less than P2, the controller controls the first driving mechanism to act, drives the first sliding ring 3 to rotate, and drives the blade 5 to twist, so that the blade 5 is in a streamline structure, and the generator is in a wind power generation state. By arranging the wind speed sensor and the illuminance sensor to detect the real-time wind speed and the illuminance, the controller can compare and judge whether the photovoltaic power generation state or the wind power generation state should be switched in this period, or the initial power generation state should be maintained, so as to realize the intelligent control of the state switching of the generator.

[0043] Preferably, the blade 5 is made of light elastic material, the blade 5 is selected from light elastic material, which can reduce the weight of the blade 5, reduce the load of the equipment, and enhance the torsion resistance of the blade 5, and prolong the service life of the blade 5.

[0044] The generator of the embodiment has three working states:

[0045] In the initial state, when the difference between P1 and P2 is less than the preset value, neither wind power generation nor photovoltaic power generation has outstanding advantages, at this time, the shape of the blade 5 is not changed, and the blade 5 remains in the vertical state, as shown in FIG. 1. Figure 2

[0046] In the photovoltaic power generation state, when the difference between P1 and P2 is greater than or equal to the preset value, and P1 is greater than P2, photovoltaic power generation has outstanding advantages over wind power generation, at this time, the controller controls the linear motor 12 to drive the second sliding ring 4 to rise, and controls the second rotating motor 13 to drive the first sliding rod 7 to rotate counterclockwise, the second sliding rod 8 drives the second sliding block 16 to rise along the second sliding groove 15, and the rotation of the first sliding rod 7 drives the top end of the blade 5 to be close to the rotating shaft 2, and the rising of the second sliding rod 8 drives the bottom end of the blade 5 to be away from the rotating shaft 2, so as to open the blade 5 to be in the shape of an umbrella, as shown in FIG. 2, which increases the light direct irradiation area of the photovoltaic power generation film 6 on the blade 5, improves the light energy collection efficiency, and thus maximizes the use of light energy for power generation. Figure 3

[0047] In the wind power generation state, when the difference between P1 and P2 is greater than or equal to the preset value, and P1 is less than P2, wind power generation has outstanding advantages over photovoltaic power generation, at this time, the controller controls the first rotating motor 9 to drive the driving gear 10 to rotate, the driving gear 10 drives the driven gear 11 to rotate, the driven gear 11 drives the first sliding ring 3 to rotate, the first sliding ring 3 drives the blade 5 to twist through the first sliding rod 7, and the twisted blade 5 is in the shape of a streamline, as shown in FIG. 3, which can collect wind energy in various directions, thereby maximizing the use of wind energy for power generation.
