[0001] This application relates to the field of solar power generation, and more particularly, to an expandable solar power generation device. Background Art

[0002] Solar power generation systems play an increasingly important role in the energy field. Traditional solar power generation systems usually adopt a fixed installation method, and their power generation units cannot be easily increased or decreased, which limits their application in different scenarios. In addition, these devices need to manually or automatically adjust the angle of the power generation units to capture the maximum energy of sunlight, increasing the complexity of operation and maintenance.

[0003] The patent document with the publication number CN117578958A discloses an expandable solar power generation device. An expandable solar power generation device includes a basic power generation component capable of independently charging electronic products; at least one expandable power generation unit, and at least one of the expandable power generation units is detachably connected to the basic power generation component. Although the above application document can improve the power generation efficiency, increase the operation flexibility and stability of the power generation system, and accurately optimize the volume and mass of the power generation device, thus facilitating carrying and transportation, when the device is assembled on a utility pole, the solar panels are in a vertical state, resulting in a poor light receiving angle and a reduced power generation efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an expandable solar power generation device, which solves the problems raised in the above background art.

[0005] To achieve the above object, the present application provides an expandable solar power generation device, including a frame, a photovoltaic rack is assembled inside the frame, and a hinge is assembled on the side of the frame; A fixing plate is assembled on the back of the frame, a support plate is hinged to the inner side of the fixing plate, a first hydraulic chamber is fixedly connected to the back of the frame, a first hydraulic rod is slidably connected to one end of the piston inside the first hydraulic chamber, a second hydraulic rod is slidably connected to one end of the piston inside the first hydraulic chamber, a second hydraulic chamber is fixedly connected to the back of the support plate, a third hydraulic rod is slidably connected to one end of the piston inside the second hydraulic chamber, a third hydraulic chamber is fixedly connected to the back of the frame, a fourth hydraulic rod is slidably connected to one end of the piston inside the third hydraulic chamber, a cleaning device for cleaning the photovoltaic panel is assembled inside the frame, and a support device for supporting the frame is assembled inside the frame.

[0006] Preferably, a receiving groove for assembling the second hydraulic chamber is opened on the back of the support plate, a connecting hose is fixedly connected to the top of the second hydraulic chamber, and the end of the connecting hose away from the second hydraulic chamber is fixedly connected to the back of the third hydraulic chamber.

[0007] Preferably, the first hydraulic rod is fixedly connected to the side of the support plate, and a notch for the movement of the second hydraulic rod and the fourth hydraulic rod is provided on the back of the frame.

[0008] Preferably, the hinge on the side of the frame can be deformed by an external force, and four photovoltaic panels are assembled on the front of the photovoltaic frame.

[0009] Preferably, the cleaning device includes a fourth hydraulic chamber, which is fixedly connected to the front of the photovoltaic frame. A fifth hydraulic rod is slidably connected to one end of the piston inside the fourth hydraulic chamber, and a sixth hydraulic rod is slidably connected to one end of the piston inside the fourth hydraulic chamber. A connecting rod is fixedly connected to the side of the sixth hydraulic rod, and a movable sleeve is slidably connected to the outer wall of the connecting rod.

[0010] Preferably, a spring is fixedly connected to the left side of the inner wall of the movable sleeve, a tapered head is fixedly connected to the side of the movable sleeve, and a limiting block is fixedly connected to the front of the photovoltaic frame.

[0011] Preferably, the support device includes a driving rod, which is fixedly connected to the side of the second hydraulic rod. A fifth hydraulic chamber is fixedly connected to the bottom of the inner wall of the frame. A seventh hydraulic rod is slidably connected to one end of the piston inside the fifth hydraulic chamber, and the seventh hydraulic rod is fixedly connected to the left side of the driving rod.

[0012] Preferably, a rubber block is hinged to the side of the inner wall of the frame, a torsion spring is fixedly connected to the back of the rubber block, and a communication groove is provided at the bottom of the inner wall of the frame.

[0013] The advantages of the present application are as follows: First, when the frame is installed on the outer wall of the utility pole, the photovoltaic frame will rotate clockwise. At this time, the support plate will open, and by stretching the first hydraulic rod, the pressure in the first hydraulic chamber will increase, thereby driving the second hydraulic rod to move and releasing the support for the photovoltaic frame. Subsequently, the photovoltaic frame will rotate counterclockwise. When the support plate fully touches the ground, the third hydraulic rod is squeezed and rises, further increasing the pressure in the second hydraulic chamber and the third hydraulic chamber, pushing the fourth hydraulic rod, and causing the photovoltaic frame to rise again and rotate clockwise.

[0014] Second, when the photovoltaic frame rises, the fifth hydraulic rod is stretched, reducing the pressure in the fourth hydraulic chamber, resulting in the descent of the sixth hydraulic rod. The sixth hydraulic rod drives the connecting rod to descend, thereby pushing the movable sleeve to descend. The descent of the movable sleeve simultaneously drives the cleaning device. By the cooperation of the tapered head and the limiting block, the movable sleeve moves left and right during the descent process, thereby improving the cleaning efficiency and ensuring the effective cleaning of the photovoltaic panels.

[0015] III. When the second hydraulic rod moves forward, the driving rod also moves forward, thereby squeezing the seventh hydraulic rod. At this time, the seventh hydraulic rod moves forward, driving the pressure inside the fifth hydraulic chamber to increase, pushing the eighth hydraulic rod to move backward, and thus driving the bottom of the rubber block to move backward. After the torsion spring is stretched, the rubber block clings to the outer wall of the electric pole, enhancing the support force of the frame and improving the stability of the photovoltaic frame.

[0024] Embodiment 1, see Figures 1 - 3 , this embodiment provides an expandable solar power generation device, including a frame 1, a photovoltaic rack 5 is assembled inside the frame 1, and a hinge 6 is assembled on the side of the frame 1; On the back of the frame 1, a fixed plate 21 is assembled. On the side of the inner wall of the fixed plate 21, a support plate 22 is hinged. On the back of the frame 1, a first hydraulic chamber 23 is fixedly connected. At one end inside the first hydraulic chamber 23, a piston is slidably connected to a first hydraulic rod 24. At one end inside the first hydraulic chamber 23, a piston is also slidably connected to a second hydraulic rod 25. On the back of the support plate 22, a second hydraulic chamber 26 is fixedly connected. At one end inside the second hydraulic chamber 26, a piston is slidably connected to a third hydraulic rod 27. On the back of the frame 1, a third hydraulic chamber 29 is fixedly connected. At one end inside the third hydraulic chamber 29, a piston is slidably connected to a fourth hydraulic rod 210. Inside the frame 1, a cleaning device 3 for cleaning the photovoltaic panels is assembled. Inside the frame 1, a support device 4 for supporting the frame 1 is assembled to enhance the stability of the frame 1, especially providing additional support during expansion. Through the coordinated work of these components, the hydraulic assembly can precisely control the expansion and contraction of the frame 1 to ensure that the photovoltaic panels can be adjusted according to different lighting conditions while maintaining the stability of the entire device. When it is necessary to expand the frame 1 to increase the irradiation area of the photovoltaic panels, the hydraulic assembly can push the support plate 22 to expand outward, thus realizing the expansion of the frame 1. On the back of the support plate 22, a receiving groove for assembling the second hydraulic chamber 26 is provided. On the top of the second hydraulic chamber 26, a connecting hose 28 is fixedly connected. The end of the connecting hose 28 far from the second hydraulic chamber 26 is fixedly connected to the back of the third hydraulic chamber 29. The hydraulic assembly can flexibly adapt to the support requirements of different sizes and positions while ensuring the stability and reliability of the hydraulic assembly. When the frame 1 needs to expand, the hydraulic oil can flow freely between the hydraulic chambers to ensure the synchronous movement of each component, thus realizing the smooth expansion and contraction of the frame 1. When the first hydraulic chamber 23 and the second hydraulic chamber 26 need to work together, the connecting hose 28 can ensure the smooth flow of the hydraulic oil, enabling the hydraulic assembly to efficiently transmit power. The first hydraulic rod 24 is fixedly connected to the side of the support plate 22. On the back of the frame 1, notches for the movement of the second hydraulic rod 25 and the fourth hydraulic rod 210 are provided. The hydraulic assembly can precisely control the position and angle of the support plate 22 while preventing the second hydraulic rod 25 from interfering with the frame 1 during operation, ensuring the stability and reliability of the system. When the second hydraulic rod 25 and the fourth hydraulic rod 210 push the photovoltaic frame 5, the design of the notches ensures the smooth movement of the second hydraulic rod 25 and the fourth hydraulic rod 210, thus realizing the smooth expansion and contraction of the frame 1. When the first hydraulic rod 24 pushes the support plate 22 to expand outward, the second hydraulic rod 25 and the fourth hydraulic rod 210 can slide freely in the notches to ensure the coordinated operation of the entire system. The hinge 6 on the side of the frame 1 can be deformed by an external force. Four photovoltaic panels are assembled on the front of the photovoltaic frame 5, enabling the photovoltaic panels to be adjusted according to different lighting conditions to ensure the best power generation efficiency while improving the flexibility and adaptability of the device. At different times or seasons, the photovoltaic panels can adjust the angle to maximize the reception of sunlight, thereby improving the power generation efficiency.When the angle of the photovoltaic panel needs to be adjusted, the deformability of the hinge 6 enables the photovoltaic frame 5 to be adjusted flexibly, ensuring that the photovoltaic panel is always in the best power generation state.

[0025] When the above device is in specific use, when the frame 1 is installed on the outer wall of the telegraph pole, the photovoltaic frame 5 will rotate clockwise around the hinge point, as Figure 3 , when the frame 1 is removed and placed on the ground, the support plate 22 opens. After the support plate 22 opens, it stretches the first hydraulic rod 24. The first hydraulic rod 24 is pulled out, and the internal pressure of the first hydraulic chamber 23 increases, driving the second hydraulic rod 25 to move backward. The second hydraulic rod 25 no longer supports the photovoltaic frame 5. After the photovoltaic frame 5 has no limit, it rotates counterclockwise around the hinge point. When the support plate 22 opens, the second hydraulic rod 25 completely retracts the support for the photovoltaic frame 5. When the support plate 22 supports the ground, it squeezes the third hydraulic rod 27, and the third hydraulic rod 27 rises. The internal pressures of the second hydraulic chamber 26, the connecting hose 28, and the third hydraulic chamber 29 increase, driving the fourth hydraulic rod 210 to move forward. The fourth hydraulic rod 210 drives the photovoltaic frame 5 to rise again and rotate clockwise around the hinge point.

[0026] Embodiment 2, see Figures 1 - 5 , on the basis of Embodiment 1, the cleaning device 3 includes a fourth hydraulic chamber 31. The fourth hydraulic chamber 31 is fixedly connected to the front of the photovoltaic frame 5. A fifth hydraulic rod 32 is slidably connected to one end of the piston inside the fourth hydraulic chamber 31. A sixth hydraulic rod 33 is slidably connected to one end of the piston inside the fourth hydraulic chamber 31. A connecting rod 34 is fixedly connected to the side of the sixth hydraulic rod 33. A movable sleeve 35 is slidably connected to the outer wall of the connecting rod 34. The cleaning device 3 can automatically clean the photovoltaic panel through the control of the hydraulic components, ensuring the cleanliness of the surface of the photovoltaic panel and improving the power generation efficiency. The precise control of the fifth hydraulic rod 32 and the sixth hydraulic rod 33 enables the cleaning device 3 to perform cleaning with different intensities and ranges according to needs, adapting to the usage requirements in different environments. When a large amount of dust accumulates on the surface of the photovoltaic panel, the hydraulic components can drive the cleaning device 3 to perform a thorough cleaning to ensure that the power generation efficiency of the photovoltaic panel is not affected. A spring 36 is fixedly connected to the left side of the inner wall of the movable sleeve 35. A tapered head 37 is fixedly connected to the side of the movable sleeve 35. A limit block is fixedly connected to the front of the photovoltaic frame 5, enabling the cleaning device 3 to flexibly adjust the cleaning intensity and position according to the condition of the surface of the photovoltaic panel, ensuring the cleaning effect and avoiding damaging the photovoltaic panel at the same time. The elastic force of the spring 36 can cause the movable sleeve 35 to automatically retract when it encounters resistance, protecting the surface of the photovoltaic panel from damage.

[0027] When the above device is in specific use, when the photovoltaic frame 5 rises, the fifth hydraulic rod 32 is stretched, the internal pressure of the fourth hydraulic chamber 31 becomes smaller, the sixth hydraulic rod 33 is driven to descend, the sixth hydraulic rod 33 drives the connecting rod 34 to descend, and while the connecting rod 34 descends, the movable sleeve 35 is driven to descend to clean the photovoltaic panel. At the same time, through the cooperation of the conical head 37 and the limit block, the movable sleeve 35 moves left and right during the descending process, improving the cleaning efficiency of the photovoltaic panel.

[0028] Embodiment 3, see Figures 6 - 7 , on the basis of Embodiment 1, the support device 4 includes a driving rod 41, the driving rod 41 is fixedly connected to the side of the second hydraulic rod 25, the bottom of the inner wall of the frame 1 is fixedly connected with a fifth hydraulic chamber 42, one end of the piston inside the fifth hydraulic chamber 42 is slidably connected with a seventh hydraulic rod 43, the seventh hydraulic rod 43 is fixedly connected to the left side of the driving rod 41, one end of the piston inside the fifth hydraulic chamber 42 is slidably connected with an eighth hydraulic rod 45. The support device 4 can accurately adjust the support position and strength through the control of the hydraulic components to ensure the stability of the frame 1 and the safety of the overall device. During the expansion or contraction of the frame 1, the hydraulic components can adjust the position of the support device 4 in real time to ensure the balance and stability of the entire device. A rubber block 46 is hinged to the side of the inner wall of the frame 1, a torsion spring 47 is fixedly connected to the back of the rubber block 46, and a communication groove 44 is opened at the bottom of the inner wall of the frame 1. Through the buffering and resetting effects of the rubber block 46 and the torsion spring 47, vibrations and impacts can be reduced, and the durability and stability of the device can be improved. The elasticity of the rubber block 46 and the torque of the torsion spring 47 can effectively absorb and release energy.

[0029] When the above device is in specific use, when the second hydraulic rod 25 moves forward, the driving rod 41 is driven to move forward, the driving rod 41 presses the seventh hydraulic rod 43, the seventh hydraulic rod 43 moves forward, the internal pressure of the fifth hydraulic chamber 42 increases, driving the eighth hydraulic rod 45 to move backward, pushing the bottom of the rubber block 46 to move backward, and at the same time the torsion spring 47 is stretched, and the rubber block 46 is pressed against the outer wall of the telegraph pole, improving the supporting force of the frame 1.

[0030] As described above, the above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
