[0002] New energy generally refers to renewable energy developed and utilized based on new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, and tidal energy, as well as hydrogen energy; while energy sources that have been widely used, such as coal, oil, natural gas, hydropower, and nuclear fission energy, are called conventional energy. New energy power generation is the process of generating electricity using existing technologies through the aforementioned new energy sources.

[0003] The main body of a new energy photovoltaic power generation device is a photovoltaic panel. Once installed, the photovoltaic panel is fixed and cannot be moved. Unlike a large wind turbine, it cannot turn when the wind direction changes. Not only can the angle and direction of the photovoltaic panel be adjusted in real time to ensure that the photovoltaic panel is always facing the sun to maximize the reception of solar radiation energy and improve power generation efficiency, but strong winds may also cause mechanical damage to the photovoltaic panel, and wind loads may impact the photovoltaic panel, thereby reducing its service life.

[0004] Therefore, it is of great importance to design a new energy photovoltaic power generation device and its power generation method that automatically tracks wind direction in order to solve the above-mentioned defects. Summary of the Invention

Multiple sets of conductive slip rings are installed on the outside of the rotating drum at positions corresponding to the brushes. Both the connector and the brushes are electrically connected to the conductive slip rings. The brushes are electrically connected to the distribution box.

[0014] Furthermore, the closing mechanism includes a connecting sleeve fixedly installed at the front end of the ventilation duct.

[0015] Furthermore, an air guide cover is fixedly installed on the front of the connecting sleeve, and both ends of the synchronizing rod are rotatably connected to the transmission plate.

[0016] The present invention also provides a power generation method, including a new energy photovoltaic power generation device that automatically tracks wind direction as described in any one of the above claims, the specific operation steps of which are as follows: S1. First, install and fix the mounting base. Use wind speed and direction sensors to monitor wind speed and direction in real time. When encountering strong winds, the ventilation pipe will be adaptively adjusted under the action of the wind vane.

When the rotating shaft rotates, it drives the sensing disk to rotate together. When the corresponding sensing slot reaches the position of the photoelectric switch, the photoelectric switch can control the first motor to cut off power in time, thereby accurately adjusting the direction of the photovoltaic panel to avoid it being affected by strong winds. When the photovoltaic panel is working, the illuminance sensor at the top of the inclined support plate can monitor the light intensity in real time.

With the connection of the connecting plate, the angle of the inclined support plate can be adjusted, thereby adjusting the photovoltaic panel to the optimal light-receiving angle to improve power generation efficiency.

[0018] 2. The device of this invention, through the coordinated design of a distribution box, support column, junction box, ventilation pipe, closing mechanism, and wind vane, utilizes wind speed and direction sensors to monitor wind speed and direction in real time. When encountering strong winds, the ventilation pipe is adaptively adjusted under the action of the wind vane. With the rotation of the rotating drum, the ventilation pipe is adjusted to the same direction as the wind. At this time, the closing mechanism is operated to open the ventilation pipe, allowing airflow to pass through. After the airflow passes through the interior of the ventilation pipe, it drives the wind turbine to generate electricity using wind power. The electricity generated by the wind turbine is conducted to multiple sets of conductive slip rings through the junction head, and then conducted to the distribution box through brushes. The distribution box is equipped with a transformer, inverter, and battery. After the wind power is transformed by the transformer, the DC power needs to be converted to AC power by the inverter. The electricity generated by the wind power supplies the positioning mechanism, adjustment mechanism, and closing mechanism, thereby avoiding waste of photovoltaic panel power generation, adjusting its direction and angle, avoiding its impact from strong winds, and greatly improving power generation efficiency.

[0021] This specific embodiment is a new energy photovoltaic power generation device that automatically tracks wind direction, and its structural schematic diagram is shown below. Figure 1-10 As shown, the device includes a mounting base 1, a housing 2 fixedly mounted on the rear end of the top of the mounting base 1, a positioning mechanism 3 installed inside the housing 2, a base plate 4 fixedly mounted on the top of the positioning mechanism 3 and above the housing 2, a diagonal brace 5 hinged to the rear end of the base plate 4, an adjustment mechanism 6 installed between the diagonal brace 5 and the base plate 4, a photovoltaic panel 7 fixedly mounted on the back of the diagonal brace 5, a distribution box 8 fixedly mounted on the front end of the top of the mounting base 1, a support column 9 fixedly mounted on the top of the distribution box 8, a junction box 10 fixedly mounted on the top of the support column 9, a ventilation pipe 11 rotatably connected to the top of the junction box 10, a closing mechanism 12 fixedly mounted on the front end of the ventilation pipe 11, a wind vane 13 fixedly mounted on the top of the ventilation pipe 11, and a wind speed and direction sensor 14 mounted on the wind vane 13.

[0022] First, the positioning mechanism 3 includes a first motor 301 fixedly installed inside the housing 2. A rotating shaft 302 is fixedly installed on the drive end of the first motor 301. The top end of the rotating shaft 302 is fixedly connected to the base plate 4 through a mounting plate 303. A support frame 304 is fixedly installed inside the housing 2 and outside the first motor 301. A photoelectric switch 305 is fixedly installed on the top of the support frame 304. An induction disk 306 is fixedly installed on the outside of the rotating shaft 302 at a position corresponding to the photoelectric switch 305. When the photovoltaic panel 7 is working, the wind speed and direction sensor 14 monitors the wind speed and direction in real time. When encountering strong winds, the first motor 301 is started to drive the rotating shaft 302 to rotate, thereby driving the base plate 4 to rotate and adjust the direction of the photovoltaic panel 7 to avoid the photovoltaic panel 7 being affected by strong winds.

[0023] Furthermore, the rotating shaft 302 is rotatably connected to the housing 2 via the bushing 307. The induction disk 306 has eight sets of induction slots 308, which are evenly distributed on the induction disk 306. When the direction of the photovoltaic panel 7 is adjusted, the eight sets of induction slots 308 on the induction disk 306 correspond to different wind directions. When the rotating shaft 302 rotates, it drives the induction disk 306 to rotate together. When the corresponding induction slot 308 reaches the position of the photoelectric switch 305, the photoelectric switch 305 can control the first motor 301 to cut off the power in time, thereby accurately adjusting the direction of the photovoltaic panel 7 to avoid it being affected by strong winds.

[0024] Then, support plates 501 are fixedly connected to the upper and lower ends of both sides of the inclined support plate 5. Fixing blocks 502 are fixedly installed on the ends of the multiple support plates 501 away from the inclined support plate 5 and on the left and right sides of the photovoltaic panel 7. A light intensity sensor 503 is fixedly installed on the top of the inclined support plate 5. The photovoltaic panel 7 is installed on the inclined support plate 5. The photovoltaic panel 7 is supported by the support plates 501. Then, the left and right ends of the photovoltaic panel 7 are fixed by the multiple sets of fixing blocks 502, so as to facilitate the disassembly and assembly of the photovoltaic panel 7 for easy maintenance.

[0025] Furthermore, the adjustment mechanism 6 includes a threaded rod 601 rotatably connected to the top of the base plate 4. A connecting seat 602 is threadedly connected to the outer side of the threaded rod 601. A connecting plate 603 is installed between the connecting seat 602 and the inclined support plate 5. A transmission gear 604 is fixedly installed at the front end of the threaded rod 601. A second motor 605 is fixedly installed at the front end of the bottom of the base plate 4. The drive end of the second motor 605 meshes with the transmission gear 604 through a drive gear 606. When the photovoltaic panel 7 is working, the illuminance sensor 503 at the top of the inclined support plate 5 can monitor the light intensity in real time. The second motor 605 drives the drive gear 606 to rotate, and under the transmission of the transmission gear 604, the threaded rod 601 rotates, thereby moving the connecting seat 602.

[0026] The threaded rod 601 is rotatably connected to the base plate 4 at both ends via bearing seats 607. The left and right sides of the connecting seat 602 are rotatably connected to movable wheels 608. The two ends of the connecting plate 603 are rotatably connected to the connecting seat 602 and the inclined support plate 5, respectively. When the connecting seat 602 moves, the movable wheels 608 on both sides roll on the base plate 4 to assist in moving the connecting seat 602. With the connection of the connecting plate 603, the angle of the inclined support plate 5 can be adjusted, thereby adjusting the photovoltaic panel 7 to the optimal light-receiving angle to improve power generation efficiency.

[0027] Secondly, a rotating drum 1001 is rotatably connected to the rear end of the junction box 10. The top end of the rotating drum 1001 is fixedly connected to the ventilation pipe 11. A wind turbine 1002 is fixedly installed inside the ventilation pipe 11 at a position corresponding to the rotating drum 1001. The top end of the rotating drum 1001 is electrically connected to the wind turbine 1002 via a connector 1003. A brush 1004 is fixedly installed at the front end of the junction box 10. Multiple sets of conductive slip rings 1005 are installed on the outside of the rotating drum 1001 at positions corresponding to the brush 1004. Both the connector 1003 and the brush 1004 are electrically connected to the conductive slip rings 1005. The brush 1004 is electrically connected to the distribution box 8. In strong winds, the ventilation pipe 11 is adaptively adjusted under the action of the wind vane 13. The rotation of the rotating drum 1001 adjusts the ventilation pipe 11. When aligned with the wind direction, the closing mechanism 12 is operated to open the ventilation pipe 11, allowing airflow to pass through. After passing through the ventilation pipe 11, the airflow drives the wind turbine 1002 to generate electricity using wind power. The electricity generated by the wind turbine 1002 is conducted through the connector 1003 to multiple sets of conductive slip rings 1005, and then through the brushes 1004 to the distribution box 8. The distribution box 8 is equipped with a transformer, inverter, and battery. After the wind power is transformed by the transformer, the DC power needs to be converted into AC power by the inverter. The electricity generated by the wind power supplies the positioning mechanism 3, the adjustment mechanism 6, and the closing mechanism 12, thereby avoiding waste of photovoltaic panel 7 power generation while adjusting its direction and angle, avoiding its impact from strong winds and greatly improving power generation efficiency.

[0028] Finally, the closing mechanism 12 includes a connecting sleeve 1201 fixedly installed at the front end of the ventilation duct 11. Multiple sets of closing plates 1202 are rotatably connected inside the connecting sleeve 1201. A connecting frame 1203 is fixedly installed inside the connecting sleeve 1201 at the center of the multiple sets of closing plates 1202. All sets of closing plates 1202 are rotatably connected to the connecting frame 1203. All sets of closing plates 1202 are rotatably connected to the connecting sleeve 1201 via synchronous shafts 1204. A transmission plate 1205 is fixedly installed at one end of each synchronous shaft 1204 located outside the connecting sleeve 1201. Synchronous rods 1206 are installed between each pair of transmission plates 1205. A third motor 1207 is fixedly installed on the outside of the connecting sleeve 1201, and the drive end of the third motor 1207 is connected to its... A set of synchronous shafts 1204 are fixedly connected, and a wind guide shroud 1208 is fixedly installed on the front of the connecting sleeve 1201. Both ends of the synchronous rod 1206 are rotatably connected to the transmission plate 1205. When it is necessary to adjust the direction and angle of the photovoltaic panel 7, the third motor 1207 is started to drive the synchronous shafts 1204 to rotate. Under the transmission of the synchronous rod 1206 and the transmission plate 1205, multiple sets of synchronous shafts 1204 can be driven to rotate at the same time, thereby driving multiple sets of closing plates 1202 to rotate at the same time. The ventilation pipe 11 is opened, and under the guidance of the wind guide shroud 1208, the airflow can quickly pass through the ventilation pipe 11, and then generate electricity by wind power. After the energy storage inside the distribution box 8 is full, the multiple sets of closing plates 1202 are closed to avoid overload caused by continuous power generation.

[0029] When using the device of this technical solution, the mounting base 1 is first installed and fixed. The wind speed and direction sensor 14 is used to monitor the wind speed and direction in real time. When encountering strong winds, the ventilation pipe 11 is adaptively adjusted under the action of the wind vane 13. Under the rotation of the rotating drum 1001, the ventilation pipe 11 is adjusted to the same direction as the wind. At this time, the closing mechanism 12 is operated to open the ventilation pipe 11 so that airflow can pass through. After the airflow passes through the interior of the ventilation pipe 11, it drives the wind turbine generator 1002 to generate electricity using wind power. The electricity generated by the wind turbine generator 1002 is transmitted through the connector. 1003 conducts the electricity to multiple sets of conductive slip rings 1005, and then through brushes 1004 to the distribution box 8. The distribution box 8 is equipped with a transformer, inverter, and battery. After the wind power is transformed by the transformer, the DC power needs to be converted to AC power by the inverter. The electricity generated by the wind power supplies the positioning mechanism 3, the adjustment mechanism 6, and the closing mechanism 12. The first motor 301 is started to drive the rotating shaft 302 to rotate. The eight sets of sensing slots 308 on the sensing disk 306 correspond to different wind directions. When the rotating shaft 302 rotates, it drives the sensing disk 306 to rotate. 06 rotates together. When the corresponding sensing slot 308 reaches the position of the photoelectric switch 305, the photoelectric switch 305 can control the first motor 301 to cut off power in time, thereby accurately adjusting the direction of the photovoltaic panel 7 to avoid it being affected by strong winds. When the photovoltaic panel 7 is working, the illuminance sensor 503 at the top of the inclined support plate 5 can monitor the light intensity in real time. The second motor 605 drives the drive gear 606 to rotate, and under the transmission gear 604, it drives the threaded rod 601 to rotate, thereby driving the connecting seat 602 to move. When the connecting... When the base 602 moves, the moving wheels 608 on both sides roll on the base plate 4 to stabilize and drive the connecting base 602 to move. With the connection of the connecting plate 603, the angle of the inclined support plate 5 can be adjusted, thereby adjusting the photovoltaic panel 7 to the optimal angle of light reception to improve power generation efficiency. The whole operation process is simple and convenient. Compared with existing new energy photovoltaic power generation devices, this invention can automatically track the wind direction by design, avoiding waste of photovoltaic panel 7 power generation, while adjusting its direction and angle to avoid being affected by strong winds and greatly improving power generation efficiency.

Use the wind speed and direction sensor 14 to monitor the wind speed and direction in real time. When encountering strong winds, the ventilation pipe 11 is adaptively adjusted under the action of the wind vane 13. Under the rotation of the rotating drum 1001, the ventilation pipe 11 is adjusted to the same direction as the wind. S2. At this time, the closing mechanism 12 is operated to open the ventilation pipe 11 so that airflow can pass through it. After the airflow passes through the ventilation pipe 11, it drives the wind turbine generator 1002 to generate electricity using wind power. S3. The electricity generated by the wind turbine 1002 is conducted to multiple sets of conductive slip rings 1005 through the connector 1003, and then to the distribution box 8 through the brush 1004. The distribution box 8 is equipped with a transformer, inverter and battery. After the wind power is transformed by the transformer, the DC power needs to be converted to AC power by the inverter to power the positioning mechanism 3, the adjustment mechanism 6 and the closing mechanism 12. S4.

10. A method for generating electricity, characterized in that: A new energy photovoltaic power generation device that automatically tracks wind direction as described in any one of claims 1-9, characterized by comprising the following steps: S1. First, install and fix the mounting base (1). Use the wind speed and direction sensor (14) to monitor the wind speed and direction in real time. When encountering strong winds, the ventilation pipe (11) is adaptively adjusted under the action of the wind vane (13). Under the rotation of the rotating drum (1001), the ventilation pipe (11) is adjusted to the same direction as the wind. S2. At this time, operate the closing mechanism (12) to open the ventilation pipe (11) so that airflow can pass through its interior. After the airflow passes through the interior of the ventilation pipe (11), it drives the wind turbine (1002) to generate electricity using wind power. S3.
