Description

TECHNICAL FIELD

[0001] The present application relates to the field of solar power generation, in particular, to an expandable solar power generation device. BACKGROUND

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

[0003] The patent document with publication number CN117578958A discloses an expandable solar power generation device. The expandable solar power generation device comprises a basic power generation assembly capable of independently charging electronic products, and at least one expansion power generation unit which is detachably connected to the basic power generation assembly. Although the above-mentioned application file can improve the power generation efficiency, increase the operation flexibility and stability of the power generation system, and accurately optimize the volume and quality of the power generation device, thereby facilitating carrying and transportation, when the device is assembled on a power pole, the solar panels are in a vertical state, which results in poor light receiving angle and reduces the power generation efficiency. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an expandable solar power generation device to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides an expandable solar power generation device, comprising a frame, the inside of the frame is assembled with a photovoltaic frame, the side of the frame is assembled with a hinge piece;

[0006] The back of the frame is assembled with a fixed plate, the inner wall side of the fixed plate is hingedly connected with a support plate, the back of the frame is fixedly connected with a first hydraulic chamber, the inside of the first hydraulic chamber is slidably connected with a first hydraulic rod at one end of the piston, the inside of the first hydraulic chamber is slidably connected with a second hydraulic rod at one end of the piston, the back of the support plate is fixedly connected with a second hydraulic chamber, the inside of the second hydraulic chamber is slidably connected with a third hydraulic rod at one end of the piston, the back of the frame is fixedly connected with a third hydraulic chamber, the inside of the third hydraulic chamber is slidably connected with a fourth hydraulic rod at one end of the piston, the inside of the frame is assembled with a cleaning device for cleaning the photovoltaic panel, and the inside of the frame is assembled with a supporting device for supporting the frame.

[0007] Preferably, the back of the support plate is provided with a containing groove for assembling the second hydraulic chamber, the top of the second hydraulic chamber is fixedly connected with a connecting hose, and the end of the connecting hose away from the second hydraulic chamber is fixedly connected to the back of the third hydraulic chamber.

[0008] Preferably, the first hydraulic rod is fixedly connected to the side of the support plate, and the back of the frame is provided with a slot for the second hydraulic rod and the fourth hydraulic rod to move.

[0009] Preferably, the hinge on the side of the frame can be deformed by external force, and the front of the photovoltaic frame is equipped with four photovoltaic panels.

[0010] Preferably, the cleaning device comprises a fourth hydraulic chamber fixedly connected to the front of the photovoltaic frame, a fifth hydraulic rod slidingly connected to the inner end of the fourth hydraulic chamber, a sixth hydraulic rod slidingly connected to the inner end of the fourth hydraulic chamber, a connecting rod fixedly connected to the side of the sixth hydraulic rod, and a movable sleeve slidingly connected to the outer wall of the connecting rod.

[0011] Preferably, the inner wall of the movable sleeve is fixedly connected to a spring on the left side, and the side of the movable sleeve is fixedly connected to a conical head, and the front of the photovoltaic frame is fixedly connected to a limiting block.

[0012] Preferably, the support device comprises a driving rod fixedly connected to the side of the second hydraulic rod, a fifth hydraulic chamber fixedly connected to the inner wall of the frame at the bottom, a seventh hydraulic rod slidingly connected to the inner end of the fifth hydraulic chamber, the seventh hydraulic rod fixedly connected to the left side of the driving rod, and an eighth hydraulic rod slidingly connected to the inner end of the fifth hydraulic chamber.

[0013] Preferably, the hinge of the inner wall of the frame is provided with a rubber block, the back of the rubber block is fixedly connected to a torsional spring, and the inner wall of the frame is provided with a communication groove at the bottom.

[0014] The application has the advantages that:

[0015] Firstly, when the frame is installed on the outer wall of the telegraph pole, the photovoltaic frame will rotate clockwise. At this time, the support plate will be opened, and the pressure of the first hydraulic chamber will be increased by the stretching of the first hydraulic rod, thereby driving the second hydraulic rod to move and releasing the support of the photovoltaic frame. Subsequently, the photovoltaic frame will rotate counterclockwise. When the support plate is fully supported, the third hydraulic rod is pressed upward, further increasing the pressure of the second hydraulic chamber and the third hydraulic chamber, pushing the fourth hydraulic rod, and making the photovoltaic frame rise again and rotate clockwise.

[0016] Secondly, after the photovoltaic frame is raised, the fifth hydraulic rod is stretched, the pressure of the fourth hydraulic chamber is reduced, and the sixth hydraulic rod is lowered. The sixth hydraulic rod drives the connecting rod to descend, and in turn drives the movable sleeve to descend. The descent of the movable sleeve simultaneously drives the cleaning device, and the cooperation of the conical head and the limiting block makes the movable sleeve move left and right during the descent process, thereby improving the cleaning efficiency and ensuring that the photovoltaic panel is effectively cleaned.

[0017] Third, this application achieves this by having the drive rod move forward when the second hydraulic rod moves forward, thereby compressing the seventh hydraulic rod. At this time, the seventh hydraulic rod moves forward, increasing the internal pressure of the fifth hydraulic chamber, which in turn pushes the eighth hydraulic rod to the back, causing the bottom of the rubber block to move backward. After the torsion spring is stretched, the rubber block adheres tightly to the outer wall of the utility pole, enhancing the frame's support and improving the stability of the photovoltaic frame.

[0033] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] In an embodiment, referring to Figures 1-3 The embodiment provides a scalable solar power generation device, which comprises a frame 1, a photovoltaic frame 5 is arranged in the frame 1, and a hinge 6 is arranged on the side of the frame 1.

[0035] The back of the frame 1 is equipped with a fixed plate 21, the inner wall side of which is hingedly connected with a support plate 22. The back of the frame 1 is fixedly connected with a first hydraulic chamber 23. The inside of the first hydraulic chamber 23 is slidably connected with a first hydraulic rod 24 at one end. The inside of the first hydraulic chamber 23 is slidably connected with a second hydraulic rod 25 at one end. The back of the support plate 22 is fixedly connected with a second hydraulic chamber 26. The inside of the second hydraulic chamber 26 is slidably connected with a third hydraulic rod 27 at one end. The back of the frame 1 is fixedly connected with a third hydraulic chamber 29. The inside of the third hydraulic chamber 29 is slidably connected with a fourth hydraulic rod 210 at one end. The inside of the frame 1 is equipped with a cleaning device 3 for cleaning photovoltaic panels. The inside of the frame 1 is equipped with a support device 4 for supporting the frame 1, which enhances the stability of the frame 1, especially when it is expanded, providing additional support. Through the coordinated work of these components, the hydraulic assembly can accurately control the expansion and contraction of the frame 1, ensuring that the photovoltaic panels can be adjusted according to different lighting conditions, while maintaining the stability of the entire device. When the frame 1 needs to be expanded to increase the illumination area of the photovoltaic panels, the hydraulic assembly can push the support plate 22 to expand outward, thereby realizing the expansion of the frame 1. The back of the support plate 22 is provided with a receiving groove for assembling the second hydraulic chamber 26. The top of the second hydraulic chamber 26 is fixedly connected with a connecting hose 28. The end of the connecting hose 28 away 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 different sizes and positions of the support requirements, while ensuring the stability and reliability of the hydraulic assembly. When the frame 1 needs to be expanded, hydraulic oil can flow freely between the hydraulic chambers, ensuring the synchronous movement of the components, thereby 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 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. The back of the frame 1 is provided with a slot for the second hydraulic rod 25 and the fourth hydraulic rod 210 to move. The hydraulic assembly can accurately control the position and angle of the support plate 22, while avoiding interference between the second hydraulic rod 25 and 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 slot ensures the smooth movement of the second hydraulic rod 25 and the fourth hydraulic rod 210, thereby 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 freely slide in the slot, ensuring the coordinated operation of the entire system. The hinge 6 on the side of the frame 1 can be deformed by external force. The front of the photovoltaic frame 5 is equipped with four photovoltaic panels, which can be adjusted according to different lighting conditions to ensure optimal power generation efficiency, while improving the flexibility and adaptability of the device. In different time periods 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.

[0036] In actual use, when the frame 1 is installed on the outer wall of a telegraph pole, the photovoltaic frame 5 rotates clockwise around the hinge point, as shown in Figure 3 When the frame 1 is removed and placed on the ground, the support plate 22 is opened, the first hydraulic rod 24 is stretched after the support plate 22 is opened, the first hydraulic rod 24 is pulled out, 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, and the photovoltaic frame 5 rotates counterclockwise around the hinge point without being limited. When the support plate 22 is opened, the second hydraulic rod 25 completely withdraws the support of the photovoltaic frame 5, and when the support plate 22 is supported, the third hydraulic rod 27 is pressed, the third hydraulic rod 27 rises, the internal pressure of the second hydraulic chamber 26, the connecting hose 28, and the third hydraulic chamber 29 increases, driving the fourth hydraulic rod 210 to move forward, and the fourth hydraulic rod 210 drives the photovoltaic frame 5 to rise again, rotating clockwise around the hinge point.

The cleaning device 3 can automatically clean the photovoltaic panel through the control of the hydraulic assembly, 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 clean at different intensities and ranges as needed, adapting to the use requirements in different environments. When a large amount of dust accumulates on the surface of the photovoltaic panel, the hydraulic assembly can drive the cleaning device 3 to clean thoroughly, ensuring that the power generation efficiency of the photovoltaic panel is not affected. The spring 36 is fixedly connected to the inner left side of the movable sleeve 35, the conical head 37 is fixedly connected to the side of the movable sleeve 35, and the limiting 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 damage to the photovoltaic panel. The spring force of the spring 36 can automatically retract the movable sleeve 35 when it is subjected to resistance, protecting the surface of the photovoltaic panel from damage.

[0038] The device is used in specific, when the photovoltaic frame 5 is raised, the fifth hydraulic rod 32 is pulled, the pressure in the fourth hydraulic chamber 31 is reduced, the sixth hydraulic rod 33 is lowered, the connecting rod 34 is lowered, the movable sleeve 35 is lowered, the photovoltaic panel is cleaned, and the movable sleeve 35 moves left and right in the process of descending, so that the cleaning efficiency of the photovoltaic panel is improved.

In the process of expansion or contraction of the frame 1, the hydraulic assembly can adjust the position of the support device 4 in real time, so that the balance and stability of the whole device are ensured. The rubber block 46 is hingedly connected to the side of the inner wall of the frame 1, the torsional spring 47 is fixedly connected to the back of the rubber block 46, and the communication groove 44 is formed in the bottom of the inner wall of the frame 1, so that the shock and impact are reduced by the buffering and resetting of the rubber block 46 and the torsional spring 47, and the durability and stability of the device are improved.
