Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic composite power generation device and a power generation method in a booster station. Background Art

[0002] In the field of new energy generation, photovoltaic hybrid power generation technology has garnered widespread attention due to its ability to integrate multiple renewable energy sources. Booster stations boost electrical energy for transmission. The electrical components within these stations rely on electricity for operation, requiring generators to provide stable power for their proper functioning. Common generators in these stations often utilize a single energy source or a simple combination of wind and solar power, resulting in numerous technical bottlenecks in practical application.

[0003] On the one hand, the coordinated working mechanism between wind and photovoltaic power generation units in traditional power generation devices is imperfect. Wind power generation is significantly affected by wind speed fluctuations. When the natural wind speed is low, the speed and power generation efficiency of the wind turbine generator drop significantly. Meanwhile, photovoltaic power generation units usually operate independently, failing to form an effective energy complement and auxiliary drive mechanism with wind power generation units, resulting in unstable overall power generation efficiency and low energy utilization.

[0004] On the other hand, the heat dissipation and temperature control issues of the energy storage unit need to be urgently addressed. In existing devices, the heat generated by the batteries during charging and discharging is difficult to dissipate efficiently, relying primarily on passive cooling structures (such as vents and heat sinks). When the equipment operates at high loads for extended periods, heat can easily accumulate inside the box, causing the batteries to overheat, thus affecting their charging and discharging performance and service life, and even posing a safety hazard.

[0005] In summary, how to improve the synergistic power generation efficiency of photovoltaic and wind energy and optimize the heat dissipation and cooling mechanism of energy storage units are key issues that need to be urgently addressed in the current field of photovoltaic composite power generation technology in booster stations.

[0048] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 The figure shows a photovoltaic hybrid power generation device in a booster station, comprising a wind power generation unit 1 and a photovoltaic power generation unit 2. Both units are located above an energy storage unit 3. The electricity generated by these units is stored within the energy storage unit 3. The photovoltaic power generation unit 2 is located outside the wind power generation unit 1 and concentric with the wind power generation unit 1.

[0049] like Figure 5As shown, the wind power generation unit 1 includes a central shaft 11, which is rotatably connected to a housing 31 via a bearing. Rotating blades 12 are fixedly mounted on the top of the central shaft 11. Wind passing through the rotating blades 12 drives the central shaft 11 to rotate. A generator 15 is mounted on the bottom of the central shaft 11. The generator 15 is located inside the housing 31. The rotation of the central shaft 11 drives the generator 15 to generate electricity. Auxiliary blades 13 are fixedly mounted in the middle of the central shaft 11, and a pressure mechanism is disposed outside the auxiliary blades 13. The pressure mechanism provides auxiliary power to the rotation of the central shaft 11 through the auxiliary blades 13, thereby increasing the rotation rate of the auxiliary blades 13.

[0052] A pressurizing assembly is provided in the pressurizing chamber 27. The first rotating shaft 28 drives the pressurizing assembly to pressurize the central shaft 11 in the pressurizing chamber 27 through the auxiliary blades 13. The pressurizing assembly includes a slide 29, which is slidably and sealedly connected to the inner wall of the pressurizing chamber 27. An eccentric rod 210 is fixedly provided in the middle of the first rotating shaft 28, and the eccentric rod 210 is hinged to the slide 29 via a transmission rod 211. The first rotating shaft 28 drives the slide 29 to slide back and forth in the pressurizing chamber 27 via the eccentric rod 210 and the transmission rod 211. A limiting boss is fixedly provided on the side wall of the pressurizing chamber 27 to limit the horizontal sliding of the slide 29. A groove is provided on the slide 29. The limiting boss is located in the groove and is slidably connected to the groove.

A plurality of ventilation holes 212 are evenly distributed on a sidewall of the fixed cylinder 24 within the pressurized chamber 27. The ventilation holes 212 face the auxiliary blades 13. A slide 29 pushes the gas within the pressurized chamber 27 through the ventilation holes 212 toward the auxiliary blades 13, accelerating the rotation of the central shaft 11 through the auxiliary blades 13 and thereby improving power generation efficiency.

[0053] like Figure 8 、 Figure 10 As shown, the interior of the housing 31 is provided with a heat dissipation structure, which is located at the top of the housing 31.

When the ambient wind speed is low and unable to drive the central shaft 11, the first motor 311 provides power to the sliding structure. The first transmission wheel 34 and the second transmission wheel 35 are connected via a synchronous belt 36. A slide 37 is located above the synchronous belt 36.

[0056] like Figure 13As shown, the refrigeration structure includes a fixed plate 322, which is fixedly mounted on a slide 37. Two parallel guide posts 323 are fixedly mounted on the fixed plate 322. A fixed block 324 is fixedly mounted on the lower portion of the guide post 323, and a first slider 325 and a second slider 326 are slidably mounted on the guide post 323. An air duct 327 is fixedly mounted between the fixed block 324, the first slider 325 and the second slider 326 on the two guide posts 323, and the air duct 327 is connected to the air cooler. The air cooler is electrically connected to the controller. Air nozzles 328 facing the battery 33 are mounted on both sides of the air duct 327. The cold air in the air duct 327 is blown toward the battery 33 through the air nozzles 328. The air nozzles 328 dissipate the hot air in the battery 33 through the heat dissipation holes 32 provided on the side wall of the box body 31. A first connecting rod 330 is hingedly connected to the fixed block 324, and a second connecting rod 331 and a third connecting rod 332 are hingedly connected to the first slider 325.

[0057] like Figure 9As shown, the transmission mechanism includes a mounting plate 313. A guide rail is fixedly mounted on the top of the housing 31 to guide the horizontal sliding of the mounting plate 313. An electric cylinder 321 is mounted on the outside of the housing 31 to drive the mounting plate 313 to slide. A third rotating shaft 314 is rotatably mounted on the top of the mounting plate 313 via a bearing seat. A second bevel gear 315 is fixedly mounted on one end of the third rotating shaft 314. The second bevel gear 315 meshes with the first bevel gear 14 fixed on the bottom end of the center shaft 11. The center shaft 11 drives the third rotating shaft 314 to rotate via the first bevel gear 14 and the second bevel gear 315. A third bevel gear 316 is fixedly mounted on the other end of the third rotating shaft 314. The third bevel gear 316 meshes with a fourth bevel gear 318 fixed on the top end of the fourth rotating shaft 317. The fourth rotating shaft 317 is rotatably connected to the mounting plate 313 via a bearing seat. A second gear 319 is fixedly mounted at the bottom end of the fourth rotating shaft 317. The second gear 319 meshes with a third gear 320 fixed to the axle of the second transmission wheel 35. An electric cylinder 321 drives the transmission mechanism to engage or disengage the transmission mechanism with the central shaft 11 and the second transmission wheel 35. When the wind provides sufficient rotational force for the central shaft 11, the electric cylinder 321 pushes the mounting plate 313 to slide toward the central shaft 11, causing the second bevel gear 315 to mesh with the first bevel gear 14, and the second gear 319 to mesh with the third gear 320, thereby driving the sliding structure to slide via the central shaft 11. Wind force can be detected using an external wind speed detector electrically connected to the controller.

[0058] An inverter is installed within the housing 31, allowing the battery 33 inside the housing 31 to provide power to external or internal electrical components. A temperature sensor is also installed within the housing 31 to monitor the temperature within the housing 31. The temperature sensor is connected to a controller. When the temperature within the housing 31 exceeds a set value, the cooling mechanism is activated to cool the battery 33, thereby lowering the temperature within the housing 31.

[0059] The power generation method based on the photovoltaic composite power generation device in the booster station includes the following steps:

[0060] S1. Wind drives the central shaft 11 to rotate through the rotating blades 12, and the central shaft 11 drives the generator 15 to generate electricity, and the electrical energy is stored in the battery 33 in the box 31.

[0061] S2. The photovoltaic panel 21 generates electricity using solar energy, and the electricity is stored in the battery 33. Wind passes through the photovoltaic panel 21 and the mounting frame 22, driving the rotating drum 23 to rotate. The rotating drum 23 drives the first rotating shaft 28 via the first transmission gear 25 and the second transmission gear 26. The first rotating shaft 28 drives the slide 29 to slide within the pressurized chamber 27 via the eccentric rod 210 and the transmission rod 211.
