Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage power stations, and particularly relates to a new energy photovoltaic energy storage power station. Background Art

[0002] A photovoltaic energy storage power station is a power facility that integrates photovoltaic power generation and energy storage functions. It converts solar energy into electrical energy through solar photovoltaic panels. During the power generation process, the excess electrical energy is stored in energy storage devices such as storage batteries. When the light is insufficient or during peak electricity demand periods, the stored electrical energy is released for the load to use, playing a role in balancing power supply and demand, stabilizing the grid voltage, improving the reliability of the power system, and the consumption capacity of renewable energy.

[0003] Currently, in common photovoltaic energy storage power stations, the angle adjustment mechanism of the photovoltaic panels and the heat dissipation and ventilation structure of the energy storage device are relatively independent. The angle adjustment of the photovoltaic panels often only considers optimizing the light angle. However, during the operation of the energy storage device, a large amount of heat is generated, and its heat dissipation and ventilation mainly rely on separate fans or ventilation openings. This leads to, on the one hand, when adjusting the angle of the photovoltaic panels, the heat dissipation requirements of the energy storage device are not taken into account. Even if the photovoltaic panels can obtain good illumination during high-temperature periods, the energy storage device is prone to performance degradation or even failure due to poor heat dissipation. On the other hand, the heat dissipation system of the energy storage device operates independently, resulting in energy waste and an unreasonable and non-compact space layout. Summary of the Invention

[0004] In view of the above situation, to overcome the deficiencies of the prior art, the present invention provides a new energy photovoltaic energy storage power station to solve the above problems.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A new energy photovoltaic energy storage power station includes an energy storage box. A power box, a control box, and a photosensitive sensor are respectively fixedly connected to the upper surface of the energy storage box. An angle adjustment unit is arranged above the energy storage box, a synchronous heat dissipation unit is arranged inside the energy storage box, an adjustment frame is arranged above the energy storage box, and a photovoltaic power generation panel is fixedly connected to the upper surface of the adjustment frame.

[0006] Preferably, the angle adjustment unit includes a stepper motor fixed to the inner wall of the power box. A plurality of support plates are fixedly connected to the upper surface of the energy storage box. The inner wall of each support plate is fixedly connected with a first bearing. The inner rings of the plurality of first bearings are jointly fixedly connected with a main shaft. The output end of the stepper motor is fixedly connected with a coupling, and one end of the coupling is fixedly connected with one end of the main shaft.

[0007] Preferably, a controller is fixedly connected to the inner wall of the control box. The controller is electrically connected to the stepper motor and the photosensitive sensor through wires respectively.

[0008] Preferably, the synchronous heat dissipation unit includes a second bearing fixed to the inner wall of the energy storage box. The inner ring of the second bearing is fixedly connected to a first connecting shaft. The outer surface of the first connecting shaft is fixedly connected to a first bevel gear and a first staggered helical gear respectively. The outer surface of the main shaft is fixedly connected to a second bevel gear. The outer surface of the first bevel gear meshes with the outer surface of the second bevel gear. The inner wall of the energy storage box is fixedly connected to a second connecting shaft. The outer surface of the second connecting shaft is fixedly connected to a second staggered helical gear. The outer surface of the first staggered helical gear meshes with the outer surface of the second staggered helical gear.

[0009] Preferably, a connecting frame is fixedly installed on the inner wall of the energy storage box by bolts. The connecting frame is located on one side of the first bevel gear. Five movable blades are rotatably connected to the inner wall of the connecting frame. A regulating rod is fixedly connected to the outer surface of each movable blade.

[0010] Preferably, two sliding plates are slidably connected inside the energy storage box. The outer surfaces of the two sliding plates are fixedly connected to a moving plate together. Five movable holes are formed in the outer surface of the moving plate. A plurality of racks are fixedly connected to the outer surface of the moving plate. The outer surface of the second staggered helical gear meshes with the racks. One end of each regulating rod penetrates through the movable hole and extends to one side of the moving plate.

[0011] Preferably, a reset block is slidably connected inside each movable hole. Two reset grooves are formed in the inner wall of each movable hole. A reset spring is fixedly connected between the inner wall of each reset groove and the upper surface of the reset block together. The outer surface of each reset block is in contact with the outer surface of the regulating rod.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. In the present invention, the stepping motor drives the main shaft to rotate, driving the photovoltaic panel to adjust the angle to track the optimal light, realizing efficient power generation. The synchronous heat dissipation unit utilizes the power of the rotation of the main shaft, such as the meshing of the second bevel gear with the first bevel gear and the first staggered helical gear with the second staggered helical gear, to drive the moving plate and the movable blades to act, adjusting the opening and closing of the ventilation opening of the energy storage box, making the heat dissipation synchronous with the angle adjustment of the photovoltaic panel. This not only optimizes the spatial layout, avoiding the space waste caused by the independent setting of each functional module in the traditional power station, but also realizes the coordinated operation between functions, greatly improving the overall performance of the system.

[0014] 2. Through precise angle adjustment combined with an efficient heat dissipation system, the present invention effectively improves the power generation efficiency and the performance of energy storage devices. The photovoltaic panels can always maintain the optimal light-receiving angle, increasing power generation. Under good heat dissipation conditions, the energy storage devices avoid performance degradation and failure risks caused by overheating, extending their service life. On the other hand, the design of structures such as the reset block and reset spring ensures the stability and reliability of heat dissipation adjustment. Even in the case of changes in the external environment or device vibration, the movable blades can maintain a stable adjustment state, maintaining a suitable temperature environment inside the energy storage box.

[0023] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings of the specification. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0024] Embodiment:

[0025] Please refer to Figures 1 to 7 Figures 1 to 7 , a new energy photovoltaic energy storage power station, including a storage box 1. The upper surface of the storage box 1 is fixedly connected with a power box 2, a control box 4 and a photosensitive sensor 5 respectively. An angle adjustment unit is arranged above the storage box 1, a synchronous heat dissipation unit is arranged inside the storage box 1, an adjustment frame 6 is arranged above the storage box 1, and a photovoltaic power generation panel 3 is fixedly connected to the upper surface of the adjustment frame 6.

[0026] Working principle: The photosensitive sensor 5 on the upper surface of the storage box 1 can sense information such as the intensity and direction of external light. The control box 4 is used to centrally control the various functions of the power station. The power box 2 provides a power source for subsequent operations such as angle adjustment. The adjustment frame 6 is used to support the photovoltaic power generation panel 3, and the angle of the adjustment frame 6 can be changed through the angle adjustment unit, thereby adjusting the orientation of the photovoltaic power generation panel 3 to enable it to receive sunlight irradiation to the greatest extent and improve the power generation efficiency. The synchronous heat dissipation unit can dissipate heat inside the storage box 1 according to the operating conditions of the power station to ensure the stable operation of the energy storage device.

[0027] Please refer to Figures 1 to 7 Figures 1 to 7 , the angle adjustment unit includes a stepper motor 12 fixed to the inner wall of the power box 2. The upper surface of the storage box 1 is fixedly connected with a plurality of support plates 10. The inner wall of each support plate 10 is fixedly connected with a first bearing 7. The inner rings of the plurality of first bearings 7 are jointly fixedly connected with a main shaft 15. The output end of the stepper motor 12 is fixedly connected with a coupling 13. One end of the coupling 13 is fixedly connected with one end of the main shaft 15. The inner wall of the control box 4 is fixedly connected with a controller 11. The controller 11 is electrically connected with the stepper motor 12 and the photosensitive sensor 5 through wires respectively.

[0028] Working principle: When the photosensitive sensor 5 detects a change in the light condition, it will transmit a signal to the controller 11 in the control box 4. The controller 11 judges whether it is necessary to adjust the angle of the photovoltaic power generation panel 3 according to the preset program and the received light signal. If adjustment is required, the controller 11 will send an instruction to the stepper motor 12 in the power box 2. After the stepper motor 12 starts, its output end starts to rotate, and the power is transmitted to the main shaft 15 through the coupling 13. The main shaft 15 is installed in the inner ring of the first bearing 7 on the inner wall of the plurality of support plates 10. The first bearing 7 can reduce the friction force when the main shaft 15 rotates, enabling the main shaft 15 to rotate smoothly. The rotation of the main shaft 15 drives the connected adjustment frame 6 to rotate, thereby realizing the angle adjustment of the photovoltaic power generation panel 3.

[0029] Please refer to Figures 1 to 7, the synchronous heat dissipation unit includes a second bearing 16 fixed to the inner wall of the energy storage box 1. The inner ring of the second bearing 16 is fixedly connected to a first connecting shaft 26. The outer surface of the first connecting shaft 26 is fixedly connected with a first bevel gear 9 and a first staggered helical gear 18 respectively. The outer surface of the main shaft 15 is fixedly connected with a second bevel gear 8. The outer surface of the first bevel gear 9 meshes with the outer surface of the second bevel gear 8. The inner wall of the energy storage box 1 is fixedly connected with a second connecting shaft 19. The outer surface of the second connecting shaft 19 is fixedly connected with a second staggered helical gear 20. The outer surface of the first staggered helical gear 18 meshes with the outer surface of the second staggered helical gear 20.

[0030] Working principle: When the angle adjustment unit works and the main shaft 15 rotates, the second bevel gear 8 fixed to the outer surface of the main shaft 15 rotates accordingly. Since the second bevel gear 8 meshes with the first bevel gear 9 on the outer surface of the first connecting shaft 26, the rotation of the second bevel gear 8 drives the first bevel gear 9 to rotate, thereby causing the first connecting shaft 26 to start rotating under the support of the second bearing 16. When the first connecting shaft 26 rotates, the first staggered helical gear 18 on its outer surface also rotates. Also, because the first staggered helical gear 18 meshes with the second staggered helical gear 20 fixed to the outer surface of the second connecting shaft 19, the first staggered helical gear 18 drives the second staggered helical gear 20 to rotate. In this way, the rotational power of the main shaft 15 is transmitted to the synchronous heat dissipation unit, preparing for subsequent heat dissipation adjustment.

[0031] Please refer to Figures 1 to 7 , the inner wall of the energy storage box 1 is fixedly installed with a connecting frame 24 through bolts. The connecting frame 24 is located on one side of the first bevel gear 9. Five movable blades 14 are rotatably connected to the inner wall of the connecting frame 24. A regulating rod 23 is fixedly connected to the outer surface of each movable blade 14.

[0032] Working principle: During the power transmission process of the synchronous heat dissipation unit, when the second staggered helical gear 20 rotates, the cooperating transmission components will drive the regulating rod 23 to act. Since the regulating rod 23 is fixed to the outer surface of the movable blade 14 and the movable blade 14 is rotatably connected to the inner wall of the connecting frame 24, the action of the regulating rod 23 will cause the movable blade 14 to rotate around the rotation point on the inner wall of the connecting frame 24. By changing the angle of the movable blade 14, the size of the air circulation channel between the inside of the energy storage box 1 and the outside can be adjusted, thereby realizing the adjustment of the heat dissipation situation inside the energy storage box 1.

[0033] Please refer to Figures 1 to 7, two sliding plates 27 are slidably connected inside the energy storage box 1. A moving plate 17 is fixedly connected to the outer surfaces of the two sliding plates 27. Five moving holes 22 are formed in the outer surface of the moving plate 17. A plurality of racks 21 are fixedly connected to the outer surface of the moving plate 17. The outer surface of the second staggered helical gear 20 meshes with the racks 21. One end of each adjusting rod 23 passes through the moving hole 22 and extends to one side of the moving plate 17.

[0034] Working principle: When the second staggered helical gear 20 rotates, since its outer surface meshes with the racks 21 on the outer surface of the moving plate 17, the rotation of the second staggered helical gear 20 will drive the moving plate 17 to slide inside the energy storage box 1 through the two sliding plates 27. Five moving holes 22 are formed in the moving plate 17. One end of the adjusting rod 23 passes through the moving hole 22. When the moving plate 17 slides, the moving hole 22 will push the adjusting rod 23 to move, thereby driving the moving blade 14 to rotate, achieving precise control of the angle of the moving blade 14, and further adjusting the heat dissipation effect of the energy storage box 1.

[0035] Please refer to Figures 1 to 7 , a reset block 28 is slidably connected inside each moving hole 22. Two reset grooves 29 are formed in the inner wall of each moving hole 22. A reset spring 25 is fixedly connected to the upper surface of the reset block 28 and the inner wall of each reset groove 29. The outer surface of each reset block 28 contacts the outer surface of the adjusting rod 23.

[0036] Working principle: When the moving plate 17 drives the adjusting rod 23 to move, the adjusting rod 23 will squeeze the reset block 28 in the moving hole 22. The reset block 28 slides in the moving hole 22 and compresses the reset spring 25 at the same time. When the moving plate 17 moves in the reverse direction or stops moving, the reset spring 25 returns to its deformed state, pushing the reset block 28 to slide in the reverse direction. The reset block 28 then pushes the adjusting rod 23 to move in the reverse direction, causing the moving blade 14 to return to the initial position or a suitable angle. The presence of the reset spring 25 and the reset block 28 ensures the stability and repeatability of the adjustment of the moving blade 14, preventing the moving blade 14 from randomly changing its angle due to mechanical vibration or other external factors.

[0037] In summary, when the overall device is in use: during the operation of the power station, the photosensitive sensor 5 on the energy storage box 1 continuously monitors information such as the light intensity and direction, and transmits it to the controller 11 in the control box 4. The controller 11 determines whether to adjust the angle of the photovoltaic panel 3 according to the preset program and the light signal. If adjustment is required, an instruction is sent to the stepper motor 12 in the power box 2. The stepper motor 12 starts, and the output end rotates, driving the main shaft 15 through the coupling 13. The main shaft 15 is installed in the inner ring of the first bearing 7 of the support plate 10 and rotates smoothly under its support, thereby driving the adjustment frame 6 and the photovoltaic panel 3 to adjust the angle to achieve efficient daylighting and power generation. At the same time, the rotation of the main shaft 15 drives the second bevel gear 8, and the second bevel gear 8 meshes with the first bevel gear 9, causing the first connecting shaft 26 to rotate under the support of the second bearing 16. The first staggered helical gear 18 on the first connecting shaft 26 rotates accordingly, and drives the second staggered helical gear 20 meshing with it to rotate, transmitting the power of the main shaft 15 to the synchronous heat dissipation unit. The second staggered helical gear 20 meshes with the rack 21 on the moving plate 17, and drives the moving plate 17 to slide in the energy storage box 1 through the sliding plate 27 when rotating. The movable hole 22 on the moving plate 17 pushes the adjusting rod 23 to move, and the adjusting rod 23 drives the movable blade 14 in the connecting frame 24 to rotate, adjusting the size of the ventilation opening of the energy storage box 1 to achieve heat dissipation adjustment. During the adjustment process, the moving plate 17 drives the adjusting rod 23 to squeeze the reset block 28, compressing the reset spring 25. When the moving plate 17 moves in the reverse direction or stops moving, the reset spring 25 recovers its deformation, pushing the reset block 28 to make the adjusting rod 23 move in the reverse direction, ensuring that the movable blade 14 returns to the appropriate angle, guaranteeing the stability and repeatability of the adjustment. This photovoltaic energy storage power station realizes the coordinated operation of the angle adjustment of the photovoltaic panel 3 and the synchronous heat dissipation of the energy storage box 1, effectively solving the problem that the two are independent in traditional power stations, improving the power generation efficiency, ensuring the stable operation of the energy storage device, and optimizing the overall performance of the power station.
