Description

Technical Field

[0001] The present invention relates to the technical field of building materials, and in particular to a metal wallboard structure capable of replacing a photovoltaic module and a use method thereof. Background Art

[0002] With the widespread application of renewable energy, photovoltaic power generation, as a clean and sustainable way of obtaining energy, has been increasingly integrated into the construction field, and the design of metal wall panels combined with photovoltaic modules has emerged.

[0003] However, there are still many problems that need to be solved for such products:

[0004] Traditional photovoltaic integrated metal wall panels often face a complex and time-consuming disassembly process when the photovoltaic panels fail or age and need to be replaced. Due to the lack of reasonable internal structure design, maintenance personnel have to remove a large number of related components, which is not only difficult to operate, but also very easy to damage the overall structure of the wall panels, increasing additional maintenance costs, making the efficiency of photovoltaic panel replacement extremely low, and seriously affecting the continuous and stable operation of the photovoltaic power generation system.

[0005] Photovoltaic panels will continue to generate heat during operation. When the heat accumulates inside the metal wall panel structure and cannot be discharged in time, the operating temperature of the photovoltaic panels will increase significantly. High temperature environment will not only reduce the photoelectric conversion efficiency of photovoltaic cells and shorten their service life, but most existing metal wall panel structures are not equipped with effective heat dissipation mechanisms, or have a single heat dissipation method and poor adjustment ability, making it difficult to adapt to different working conditions and ambient temperature changes, and unable to ensure that the photovoltaic system is in the best working state for a long time.

[0006] In daily operation and maintenance and usage scenarios, the existing photovoltaic metal wall panel structure relies on manual operation for the opening and closing of the top cover, heat dissipation adjustment, etc. This not only consumes manpower and time, but also makes it difficult to accurately control the timing of the operation. For example, it is impossible to open the heat dissipation device in time according to temperature changes, or it is difficult for a single person to successfully complete a series of complex actions when replacing photovoltaic panels, which limits the development of intelligent management and efficient operation and maintenance of the entire photovoltaic system.

[0007] In summary, in order to overcome the above defects, it is urgently necessary to develop a metal wall panel structure for replaceable photovoltaic modules that can realize convenient replacement of photovoltaic panels and has efficient heat dissipation capabilities and a high degree of automation. Summary of the invention

[0012] Furthermore, a slide groove is provided at the intersection of the frame and the pull rod, and the pull rod is slidably inserted in the slide groove.

[0013] Furthermore, a door-shaped frame is provided on one side of the frame body close to the locking buckle, and a compression spring is provided on the inner wall of the door-shaped frame, and the compression spring is in contact with the side wall of the vertical rod.

[0014] Furthermore, a temperature sensor is provided on the inner wall of the frame.

After the photovoltaic panel is installed, the controller drives the first electric push rod in reverse to complete the top cover closing and locking operations in sequence.

[0017] A metal wall panel structure that can replace a photovoltaic module, and a method for using the metal wall panel structure includes the following steps:

[0018] S1. When replacing the photovoltaic panel, a replacement instruction is input to the automatic control module, and the automatic control module controls the first electric push rod to start. The first electric push rod connected to the wedge block runs first, and the wedge block moves upward with its output shaft, and uses the extrusion slope to squeeze the pressure rod, so that the pressure rod drives the locking buckle to slide horizontally, unlocking the top cover; then, the first electric push rod connected to the push rod runs, the push rod pushes one end of the connecting rod to descend, and the other end of the connecting rod presses the pull rod downward, and the pull rod drives the rack to descend through the first connecting rod, and the rack drives the gear to rotate, driving the top cover to flip open around the rotating shaft. At the same time, the photovoltaic panel moves to the outside of the frame under the action of the remaining first electric push rods, and the old photovoltaic panel is removed and replaced with a new photovoltaic panel;

[0019] S2. When installing the photovoltaic panel, the automatic control module controls the first electric push rod to move in the opposite direction, first driving the top cover to flip around the rotating shaft and close. During the closing process, the compression spring in the gantry pushes the vertical rod, driving the locking buckle to reset and fix the top cover;

[0020] S3. During heat dissipation, the temperature sensor monitors the internal temperature of the frame in real time. When the temperature exceeds the preset threshold, the automatic control module controls the second electric push rod to start, and the second electric push rod extends or contracts, and drives the articulated frame to rise or fall through the second connecting rod. The articulated frame drives the connecting frame to rotate, and the connecting frame drives the wind shield to rotate around the hinge point between it and the frame, so as to realize the leakage of hot air flow inside the frame and reduce the internal temperature.

[0021] Frame and photovoltaic panel: The core part includes a rectangular hollow frame, and the photovoltaic panel is horizontally embedded inside the frame. Support angle plates are fixed at the bottom of the four corners of the photovoltaic panel. These support angle plates are closely connected to the inner wall of the frame to provide stable support for the photovoltaic panel. In addition, a first electric push rod is set in the middle of the two ends of the bottom of the photovoltaic panel. Its top shaft end abuts against the bottom of the photovoltaic panel, playing a key role in the movement of the photovoltaic panel.

[0022] Top cover and related components: The top of the frame is hinged with a top cover through a rotating shaft, and linkage switch components are configured at both ends of the rotating shaft to control the automatic flipping and opening and closing of the top cover. The component contains a gear sleeved on the rotating shaft, the gear meshes with the vertical rack, the rack is connected to the connecting rod and the top rod inside the frame through the first connecting rod and the pull rod, and the top rod is connected to the output shaft of the first electric push rod. A linkage locking component is provided at the end of the top cover away from the rotating shaft, which is composed of a locking buckle, a vertical rod, a pressure rod, and a wedge block. The wedge block is connected to the output shaft of the first electric push rod. Through the coordination of various components, the locking and unlocking status of the top cover can be accurately controlled.

[0023] Heat dissipation assembly: Heat dissipation assembly is set at both ends of the frame, which is composed of multiple windshields hinged on the side walls of the frame, a connecting frame, an articulated frame, a second connecting rod and a second electric push rod. The windshield can rotate under the drive of the second electric push rod to achieve ventilation and heat dissipation inside the frame and outside.

[0025] 1. The unique linkage switch and locking component design, combined with the electric push rod, makes the photovoltaic panel replacement operation simple and efficient, without the need for complex tools and cumbersome processes, reducing operation and maintenance costs and time costs.

[0026] 2. The temperature sensor is combined with the heat dissipation component and the automatic control module to realize intelligent sensing and temperature regulation, avoiding the problems of reduced power generation efficiency and shortened life of photovoltaic panels due to high temperature, and ensuring stable power generation of the system.

[0042] Example 1

[0043] See also Figures 1 to 8

[0044] The present invention discloses a metal wall panel structure of a replaceable photovoltaic module, which is mainly composed of a frame 1, a photovoltaic panel 2, a supporting angle plate 3, a top cover 4 and other components. The frame 1 is rectangular and hollow, providing a basic support frame for the entire structure. The photovoltaic panel 2 is horizontally embedded in the frame 1, and its four corners are fixed to the inner wall of the frame 1 through the supporting angle plates 3 at the bottom position to ensure the stability of the installation of the photovoltaic panel 2. A first electric push rod 13 is provided at the middle position at both ends of the bottom of the photovoltaic panel 2, and the top shaft ends of these first electric push rods 13 are abutted against the bottom of the photovoltaic panel 2, which plays a key role in the subsequent replacement and maintenance operations of the photovoltaic panel. The top of the frame 1 is hinged with a top cover 4 through a rotating shaft 5 to protect the internal photovoltaic panel.

[0045] Linkage switch assembly to achieve top cover flip

[0046] Structural composition: The linkage switch assembly is used to control the automatic flipping and opening and closing of the top cover 4. It mainly includes gears 6 sleeved on both ends of the rotating shaft 5, and one side of the gear 6 is vertically meshed with a rack 7. The bottom of the rack 7 is connected to the same first connecting rod 8, and a pull rod 9 is provided at the bottom center of the first connecting rod 8. The lower part of the pull rod 9 slides through the side wall of the frame 1 and extends into the inside thereof. A bracket 10 is provided on the inner side wall of the frame 1 near the tail end of the pull rod 9, and a connecting rod 11 is hinged on the top of the bracket 10. A top rod 12 is provided at the end of the connecting rod 11 away from the frame 1, and the top rod 12 is connected to the output shaft of the first electric push rod 13.

[0047] Working process: When the top cover 4 needs to be opened to replace the photovoltaic panel, the first electric push rod 13 receives the control signal and starts to move, pushing the top rod 12. The top rod 12 is stressed so that the connecting rod 11 rotates around the hinge point of the bracket 10, and the other end of the connecting rod 11 presses down the pull rod 9. After the pull rod 9 is stressed, it drives the first connecting rod 8 and the rack 7 to descend. Due to the meshing relationship between the rack 7 and the gear 6, the gear 6 rotates, thereby driving the top cover 4 to flip around the rotating shaft 5 and open.

[0048] Linkage locking assembly secures top cover position

[0049] Structural composition: The linkage locking assembly is responsible for fixing the position of the top cover 4. It includes a locking buckle 17 which is horizontally arranged at the top of the end of the top cover 4 away from the rotating shaft 5. The end of the locking buckle 17 is vertically connected to the vertical rod 16. The bottom end of the vertical rod 16 is horizontally provided with a pressure rod 15. The pressure rod 15 slides horizontally through the outer wall of the frame 1 and extends to the inside. The end of the pressure rod 15 slides against a wedge block 14 on the inclined surface. The wedge block 14 is connected to the output shaft of the adjacent first electric push rod 13. In addition, a door frame 18 is provided on the side of the frame 1 close to the locking buckle 17. A compression spring 19 is provided on the inner wall of the door frame 18. The compression spring 19 abuts against the side wall of the vertical rod 16.

[0050] Working process: When opening the top cover 4, the first electric push rod 13 drives the wedge block 14 to move upward, and the extrusion inclined surface 141 of the wedge block 14 squeezes the inclined surface of the pressure rod 15, and the pressure rod 15 slides horizontally, thereby driving the locking buckle 17 to slide horizontally, thereby unlocking the top cover 4. When the wedge block 14 continues to rise, when its buffer straight surface 142 abuts against the end of the pressure rod 15, the locking buckle 17 no longer slides. When closing the top cover 4 to install the photovoltaic panel, the first electric push rod 13 moves in the opposite direction, and the top cover 4 is closed first, and then the vertical rod 16 is pushed by the elastic force of the compression spring 19, so that the locking buckle 17 is reset and the top cover 4 is fixed again.

[0051] Heat dissipation components regulate temperature

[0052] Structural composition: The heat dissipation assembly is arranged at both ends of the frame 1 for dissipating heat inside. It includes a plurality of windshield plates 20 hinged to the side walls at both ends of the frame 1, the bottom of each windshield plate 20 is hinged with a connecting frame 21, the top of each connecting frame 21 on the adjacent side is hinged with the same hinge frame 22, the bottom of each hinge frame 22 on the adjacent side is provided with the same second connecting rod 23, the bottom of each second connecting rod 23 is provided with a second electric push rod 24, and a temperature sensor 25 is provided on the inner wall of the frame 1.

[0053] Working process: The temperature sensor 25 monitors the internal temperature of the frame 1 in real time and transmits the data to the automatic control module. When the temperature exceeds the preset threshold, the automatic control module controls the second electric push rod 24 to start. The second electric push rod 24 extends or contracts, and drives the articulated frame 22 to rise or fall through the second connecting rod 23. The movement of the articulated frame 22 drives the connecting frame 21 to rotate, and the connecting frame 21 further drives the windshield 20 to rotate around the hinge point between it and the frame 1, so that the hot air flow inside the frame 1 can be discharged, achieving a cooling effect.

[0054] Automatic control module coordinates the operation of various components

[0055] The automatic control module is the "brain" of the entire system. It includes a controller, which is electrically connected to the temperature sensor 25, the first electric push rod 13, and the second electric push rod 24. In the scenario of replacing photovoltaic panels, when receiving the replacement operation instruction, the controller sends a driving signal to the two first electric push rods 13 in sequence, first driving the first electric push rod 13 connected to the wedge 14 to unlock the top cover 4; then driving the first electric push rod 13 connected to the top rod 12 to open the top cover 4. In the heat dissipation demand scenario, the temperature sensor 25 transmits the temperature signal exceeding the threshold, and the controller sends a start instruction to the second electric push rod 24 to accurately control the opening and closing angle of the windshield 20, maintain the appropriate temperature in the frame 1, and ensure the stable operation of the photovoltaic panel 2. A slide groove 26 is provided at the intersection of the frame 1 and the pull rod 9, and the pull rod 9 is slidably inserted inside the slide groove 26, and a spring structure for controlling the pull rod 9 to rise and reset is provided inside the slide groove 26. This structure assists the linkage switch assembly to reset after the action, preparing for the next operation.

[0056] Photovoltaic panel replacement process: When the photovoltaic panel needs to be replaced, the first electric push rod 13 is started, and the first electric push rod 13 connected to the wedge block 14 moves first, pushing the wedge block 14 upward. The extrusion slope 141 of the wedge block 14 squeezes the pressure rod 15, causing the pressure rod 15 to slide horizontally, driving the locking buckle 17 to unlock the top cover 4. Subsequently, another first electric push rod 13 drives the top rod 12 to push the connecting rod 11, and the connecting rod 11 presses the pull rod 9 downward, and the rack 7 drives the gear 6 to rotate through transmission, and the top cover 4 flips open. At the same time, the photovoltaic panel 2 moves to the outside of the frame 1 with the help of the remaining first electric push rods 13, which is convenient for replacement.

[0057] Reset and lock of the top cover: When installing a new photovoltaic panel, the first electric push rod 13 runs in the reverse direction. The top cover 4 is first closed around the rotating shaft 5. At this time, the compression spring 19 in the door frame 18 pushes the vertical rod 16, driving the locking buckle 17 to reset and firmly fix the top cover 4.

[0058] Heat dissipation adjustment mechanism: The temperature sensor 25 on the inner wall of the frame 1 monitors the internal temperature in real time. Once the temperature exceeds the preset threshold, the signal is transmitted to the automatic control module, and the automatic control module drives the second electric push rod 24 to move. The second electric push rod 24 drives the articulated frame 22 to rise and fall through the second connecting rod 23, prompting the connecting frame 21 to rotate, and the windshield 20 opens and closes accordingly, realizing the discharge of hot air flow and reducing the internal temperature.

[0059] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The first electric push rod (13) connected to the wedge block (14) runs first, and the wedge block (14) moves upward with its output shaft, and uses the extrusion inclined surface (141) to squeeze the pressure rod (15), so that the pressure rod (15) drives the locking buckle (17) to slide horizontally, unlocking the top cover (4); then, the first electric push rod (13) connected to the top rod (12) runs, and the top rod (12) pushes one end of the connecting rod (11) to descend, and the other end of the connecting rod (11) presses the pull rod (9) downward, and the pull rod (9) drives the rack (7) to descend through the first connecting rod (8), and the rack (7) drives the gear (6) to rotate, driving the top cover (4) to flip around the rotating shaft (5) and open. At the same time, the photovoltaic panel (2) moves to the outside of the frame (1) under the action of the remaining first electric push rods (13), and the old photovoltaic panel is removed and replaced with a new photovoltaic panel; S2. When installing the photovoltaic panel, the automatic control module controls the first electric push rod (13) to move in the reverse direction, first driving the top cover (4) to flip around the rotating shaft (5) and close. During the closing process, the compression spring (19) in the door frame (18) pushes the vertical rod (16), driving the locking buckle (17) to reset, thereby fixing the top cover (4); S3. During heat dissipation, the temperature sensor (25) monitors the internal temperature of the frame (1) in real time. When the temperature exceeds a preset threshold, the automatic control module controls the second electric push rod (24) to start, and the second electric push rod (24) extends or contracts, driving the articulated frame (22) to rise or fall through the second connecting rod (23), and the articulated frame (22) drives the connecting frame (21) to rotate, and the connecting frame (21) drives the windshield plate (20) to rotate around the hinge point between it and the frame (1), so as to achieve the discharge of hot air flow inside the frame (1) and reduce the internal temperature.
