Description

Technical Field

[0001] This application relates to the technical field of photovoltaic power generation equipment, and in particular to a windproof device for a photovoltaic power generation structure. Background Technology

[0002] Photovoltaic power generation structures are typically installed outdoors, making them highly susceptible to strong winds. Strong winds can damage photovoltaic panels or twist and deform the support structures, and may even cause the entire photovoltaic power generation system to collapse, resulting in incalculable economic losses for photovoltaic power generation companies.

[0003] Existing windproof devices include a base, mounting frame, lifting support rod, and lifting drive assembly. The two ends of the lifting support rod are pivotally connected to the mounting frame and the lifting drive assembly, respectively. The lifting drive assembly drives the lifting support rod, which in turn drives the mounting frame to rotate. This design requires the lifting drive assembly and the lifting support rod to work together to rotate the mounting frame, resulting in a relatively complex drive structure. Current windproof devices suffer from this problem of complex drive structures. Utility Model Content

[0004] The purpose of this application is to provide a windproof device for a photovoltaic power generation structure with a simplified drive structure, including a frame, a photovoltaic panel adjustment frame, and a telescopic assembly. The photovoltaic panel adjustment frame is pivotally connected to the frame. The telescopic assembly is pivotally connected to both the frame and the photovoltaic panel adjustment frame, and the telescopic assembly drives the photovoltaic panel adjustment frame to rotate when it extends or retracts.

[0005] Optionally, the photovoltaic panel adjustment frame includes a first support and a second support, which are spaced apart and pivotally connected to the frame.

[0006] Optionally, the frame includes a fixed support for fixing to the ground.

[0007] Optionally, the windproof device of the photovoltaic power generation structure further includes a first proximity switch, which is electrically connected to the telescopic component. The first proximity switch is used to generate a signal to stop the telescopic component from shortening when it detects that the photovoltaic panel adjustment frame has rotated from the windproof state to the working state.

[0008] Optionally, the windproof device of the photovoltaic power generation structure further includes a dual-color indicator light. The first proximity switch and the dual-color indicator light are electrically connected. The first proximity switch is also used to generate a signal to turn the dual-color indicator light green when it detects that the photovoltaic panel adjustment frame has rotated from the windproof state to the working state.

[0009] Optionally, the telescopic assembly passes through the frame.

[0010] Optionally, the windproof device of the photovoltaic power generation structure further includes a second proximity switch, which is electrically connected to the telescopic component. The second proximity switch is used to generate a signal to stop the telescopic component from extending when it detects that the photovoltaic panel adjustment frame has rotated from the working state to the windproof state.

[0011] Optionally, the windproof device of the photovoltaic power generation structure further includes a dual-color indicator light. The second proximity switch is electrically connected to the dual-color indicator light. The second proximity switch is also used to generate a signal to turn the dual-color indicator light red when it detects that the photovoltaic panel adjustment frame has rotated from the working state to the windproof state.

[0012] Optionally, the windproof device of the photovoltaic power generation structure further includes a third proximity switch, which is electrically connected to the telescopic component. The third proximity switch is used to generate a signal to stop the telescopic component from shortening when the photovoltaic panel adjustment frame is detected to rotate from the windproof state to the working state.

[0013] Optionally, the windproof device of the photovoltaic power generation structure further includes a dual-color indicator light, a first proximity switch, and a second proximity switch. The dual-color indicator light and the first proximity switch are electrically connected, and the dual-color indicator light and the second proximity switch are electrically connected. When the photovoltaic panel adjustment frame rotates from the windproof state to the working state, the first proximity switch is triggered. When the photovoltaic panel adjustment frame rotates from the working state to the windproof state, the second proximity switch is triggered. When the first proximity switch or the second proximity switch is not triggered by the photovoltaic panel adjustment frame, the dual-color indicator light is not lit.

[0014] The beneficial effects of this application are as follows: by setting up a frame, a photovoltaic panel adjustment frame, and a telescopic assembly. The photovoltaic panel adjustment frame and the frame are pivotally connected. The telescopic assembly is pivotally connected to both the frame and the photovoltaic panel adjustment frame, and the telescopic assembly drives the photovoltaic panel adjustment frame to rotate when it extends or retracts.

[0015] By connecting the telescopic components to the frame and the photovoltaic panel adjustment frame respectively, and driving the photovoltaic panel adjustment frame to rotate, a single telescopic component can make the photovoltaic panel adjustment frame rotate, eliminating the need for multiple drive components to work together, thus simplifying the drive structure of the windproof device.

[0042] like Figure 1 As shown, this embodiment provides a windproof device for a photovoltaic power generation structure, including a frame 1, a photovoltaic panel adjustment frame 2, and a telescopic assembly 3. The photovoltaic panel adjustment frame 2 is pivotally connected to the frame 1. The telescopic assembly 3 is pivotally connected to both the frame 1 and the photovoltaic panel adjustment frame 2, and the telescopic assembly 3 drives the photovoltaic panel adjustment frame 2 to rotate when it extends or retracts.

[0043] like Figure 1 As shown, the telescopic component 3 is pivotally connected to the frame 1 and the photovoltaic panel adjustment frame 2 respectively, and drives the photovoltaic panel adjustment frame 2 to rotate. A single telescopic component 3 is sufficient to make the photovoltaic panel adjustment frame 2 rotate, eliminating the need for multiple drive components to work together, thus simplifying the drive structure of the windproof device.

[0044] Please also refer to Figure 1 and Figure 2The frame 1 can be constructed by welding, screwing, or riveting multiple square steel pipes. The frame 1 includes a frame 10 and a base frame 11. The frame 10 can be composed of eight square steel pipes or channel steel, and the base frame 11 can be composed of four square steel pipes or channel steel. The bottom of the frame 10 and the base frame 11 can be connected by welding. The photovoltaic panel adjustment frame 2 can be plate-shaped. The width of the photovoltaic panel adjustment frame 2 can be approximately the same as the width of the frame 1.

[0045] Please also refer to Figure 1 and Figure 2 The photovoltaic panel can be mounted on the upper surface of the photovoltaic panel adjustment frame 2 and rotate with the photovoltaic panel adjustment frame 2. The photovoltaic panel adjustment frame 2 can be made of aluminum alloy or steel. The middle part of the photovoltaic panel adjustment frame 2 can be pivotally connected to the top right end of the frame 10. The telescopic component 3 can be a hydraulic cylinder, a pneumatic cylinder, or an electric rod. The number of telescopic components 3 can be a single one. A crossbeam 12 can be set on the base frame 11, and the rear part of the telescopic component 3 can be pivotally connected to the crossbeam 12. The crossbeam 12 can be located inside the frame 10 and overlap the two sides of the base frame 11. The top front part of the telescopic component 3 can be pivotally connected to the middle position of the lower bottom surface of the photovoltaic panel adjustment frame 2.

[0046] Please also refer to Figure 1 and Figure 2 Optionally, the photovoltaic panel adjustment frame 2 includes a first support 20 and a second support 21, which are spaced apart and pivotally connected to the frame 1.

[0047] Please also refer to Figure 1 and Figure 2 The first support 20 and the second support 21 are pivotally connected to the frame 1, and the front top of the telescopic component 3 is pivotally connected to the photovoltaic panel adjustment frame 2. The first support 20, the second support 21, the telescopic component 3, and the photovoltaic panel adjustment frame 2 are intermittently arranged at their pivot points. Thus, the frame 1 can be pivotally connected to the photovoltaic panel adjustment frame 2 through the first support 20 and the second support 21, and the telescopic component 3 is pivotally connected to another position of the photovoltaic panel adjustment frame 2. That is, there are at least three connection points on the photovoltaic panel adjustment frame 2, two of which are the first support 20 and the second support 21, and the remaining one is pivotally connected to the telescopic component 3. This can prevent the photovoltaic panel adjustment frame 2 from being unstable due to too few connection points.

[0048] Please also refer to Figure 1 and Figure 2 The photovoltaic panel adjustment frame 2 includes a plate-shaped body 23, with a first support 20 and a second support 21 respectively disposed on both sides of the bottom surface of the middle part of the body 23. The first support 20 and the second support 21 can be fixed to the body 23 by welding or integral molding. The first support 20 and the second support 21 can be made of steel plate and are parallel to each other. The body 23 can rotate about the pivot of the first support 20 and the second support 21.

[0049] Please also refer to Figure 1 and Figure 2 Optionally, the frame 1 includes a fixed support 13 for fixing to the ground. This arrangement improves the grip of the windproof device, thereby enhancing its wind resistance. The fixed support 13 can be fixed to the lower end of the base frame 11 by welding. There can be up to four fixed supports 13. The fixed support 13 can be a square steel pipe. The fixed support 13 can be fixed to the ground using pre-embedded bolts.

[0050] like Figure 2 As shown, optionally, the windproof device of the photovoltaic power generation structure also includes a first proximity switch 4, which is electrically connected to the telescopic component 3. The first proximity switch 4 is used to generate a signal to stop the telescopic component 3 from shortening when it detects that the photovoltaic panel adjustment frame 2 has rotated from the windproof state to the working state.

[0051] Please also refer to Figure 1 and Figure 2 The first proximity switch 4 generates a signal to stop the telescopic component 3 from shortening when it detects that the photovoltaic panel adjustment frame 2 has rotated from the windproof state to the working state. This prevents the photovoltaic panel adjustment frame 2 from rotating excessively and deviating from its normal working state. The first proximity switch 4 can be a non-contact proximity switch such as a photoelectric or capacitive type. The first proximity switch 4 can be electrically connected to the telescopic component 3 via a wire.

[0052] Please also refer to Figure 1 and Figure 2 For example, the first proximity switch 4 can be an infrared limit switch. The first proximity switch 4 can be located on the front right side of the base frame 11. The windproof state of the photovoltaic panel adjustment frame 2 can be defined as the photovoltaic panel adjustment frame 2 being in a state where power generation is stopped. For example, the photovoltaic panel adjustment frame 2 can be defined as being in a windproof state when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is 0°.

[0053] Please also refer to Figure 1 and Figure 2 The working state of the photovoltaic panel adjustment frame 2 can be defined as the photovoltaic panel adjustment frame 2 being in a power generation state. For example, any angle value within the range of ≥30° and ≤40° between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane can be defined as the photovoltaic panel adjustment frame 2 being in a working state.

[0054] like Figure 1As shown, for example, when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is 30 degrees, the distance between the first proximity switch 4 and the bottom surface of the photovoltaic panel adjustment frame 2 is set as the first preset distance. When the first proximity switch 4 detects that the photovoltaic panel adjustment frame 2 rotates clockwise (clockwise rotation means rotating from the windproof state to the working state) to the distance detected by the first proximity switch 4 is the first preset distance, a signal is sent to stop the photovoltaic panel adjustment frame 2 from rotating further (that is, a signal is sent to stop the telescopic component 3 from shortening).

[0055] like Figure 1 As shown, optionally, the windproof device of the photovoltaic power generation structure also includes a dual-color indicator light 5. The first proximity switch 4 is electrically connected to the dual-color indicator light 5. The first proximity switch 4 is also used to generate a signal that turns the dual-color indicator light 5 green when it detects that the photovoltaic panel adjustment frame 2 has been rotated from the windproof state to the working state. By having the dual-color indicator light 5 turn green, it is possible to visually indicate whether the photovoltaic panel adjustment frame 2 has been adjusted to the working state, which facilitates manual inspection of the status of the windproof device.

[0056] Please also refer to Figure 1 and Figure 2 For example, when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is ≥30° and ≤40° (e.g., an angle of 30°), the first proximity switch 4 can generate a signal to turn the dual-color indicator light 5 green. The dual-color indicator light 5 can be located on the left side of the top surface of the frame 10. The first proximity switch 4 and the dual-color indicator light 5 can be electrically connected by wires.

[0057] like Figure 1 As shown, optionally, the telescopic component 3 is installed through the frame 1. This arrangement allows the internal space of the frame 1 to accommodate the telescopic component 3, making the structure of the windproof device more compact. When the telescopic component 3 is a hydraulic cylinder or a pneumatic cylinder, the cylinder barrel of the hydraulic cylinder or pneumatic cylinder can be installed through the frame 10.

[0058] like Figure 1 As shown, optionally, the windproof device of the photovoltaic power generation structure also includes a second proximity switch 6, which is electrically connected to the telescopic component 3. The second proximity switch 6 is used to generate a signal to stop the telescopic component 3 from extending when it detects that the photovoltaic panel adjustment frame 2 has rotated from the working state to the windproof state. This configuration can prevent the photovoltaic panel adjustment frame 2 from rotating excessively and colliding with the frame 1, thus preventing damage to the photovoltaic panel adjustment frame 2.

[0059] like Figure 1 As shown, the second proximity switch 6 can be a non-contact proximity switch such as a photoelectric or inductive type. The second proximity switch 6 can be electrically connected to the telescopic component 3 via a wire. For example, the second proximity switch 6 can be an infrared limit switch. The second proximity switch 6 can be located on the top left side of the frame 10.

[0060] like Figure 3 As shown, for example, a photovoltaic panel adjustment frame 2 (such as photovoltaic panel adjustment frame 2) can be used. Figure 1 When the angle between the bottom surface and the horizontal plane of the photovoltaic panel (as shown below) is 0°, the distance between the second proximity switch 6 and the photovoltaic panel adjustment frame 2 at this time is set as the second preset distance. When the second proximity switch 6 detects that the photovoltaic panel adjustment frame 2 rotates counterclockwise (counterclockwise rotation means rotating from the working state to the windproof state) to the distance detected by the second proximity switch 6 is the second preset distance, a signal is sent to stop the photovoltaic panel adjustment frame 2 from rotating further (at this time, the telescopic component 3 stops extending).

[0061] like Figure 3 As shown, optionally, the windproof device for the photovoltaic power generation structure also includes a dual-color indicator light 5, a second proximity switch 6 electrically connected to the dual-color indicator light 5, and the second proximity switch 6 is also used to detect the photovoltaic panel adjustment frame 2 (such as...). Figure 1 (As shown below, the signal that turns the dual-color indicator light 5 red is generated when the device is rotated from the working state to the windproof state.)

[0062] like Figure 3 As shown, the red light on the dual-color indicator light 5 provides a visual indication of whether the photovoltaic panel adjustment frame 2 has been adjusted to the windproof state, facilitating manual inspection of the windproof device's status. For example, when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is 0°, the second proximity switch 6 can generate a signal to turn the dual-color indicator light 5 red. The second proximity switch 6 and the dual-color indicator light 5 can be electrically connected via wires.

[0063] Please also refer to Figure 1 and Figure 2 Optionally, the windproof device for the photovoltaic power generation structure also includes a third proximity switch 7, which is electrically connected to the telescopic component 3. The third proximity switch 7 is used to generate a signal to stop the telescopic component 3 from retracting when it detects that the photovoltaic panel adjustment frame 2 has rotated from the windproof state to the working state. With this configuration, even if the first proximity switch 4 fails, the third proximity switch 7 can still be used to stop the telescopic component 3 from retracting, preventing the photovoltaic panel adjustment frame 2 from rotating excessively and deviating from the normal working state, thus improving the reliability of the windproof device.

[0064] like Figure 2 As shown, the third proximity switch 7 can be a non-contact proximity switch such as a photoelectric or capacitive type. For example, the third proximity switch 7 can be an infrared limit switch. The third proximity switch 7 can be electrically connected to the dual-color indicator light 5 and the telescopic assembly 3 via wires. The third proximity switch 7 can be located on the rear right side of the base frame 11.

[0065] The third proximity switch 7 is also used to generate a signal that turns the dual-color indicator light 5 green when the photovoltaic panel adjustment frame 2 is detected to have rotated from the windproof state to the working state. For example, when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is ≥30° and ≤40° (e.g., when the angle is 30°), the third proximity switch 7 can generate a signal that turns the dual-color indicator light 5 green.

[0066] Please also refer to Figure 1 and Figure 2 For example, when the angle between the bottom surface of the photovoltaic panel adjustment frame 2 and the horizontal plane is 30 degrees, the distance between the third proximity switch 7 and the photovoltaic panel adjustment frame 2 at this time can be set as a first preset distance. Then, when the third proximity switch 7 detects that the photovoltaic panel adjustment frame 2 has rotated to a distance of the first preset distance from the third proximity switch 7, it sends a signal to stop the photovoltaic panel adjustment frame 2 from rotating further (i.e., the telescopic component 3 stops shortening). The specifications (shape, size, and model, etc.) of the third proximity switch 7 and the first proximity switch 4 can be the same.

[0067] Please also refer to Figure 1 and Figure 2 The windproof device also includes a dual-color indicator light 5, a first proximity switch 4, and a second proximity switch 6. The dual-color indicator light 5 and the first proximity switch 4 are electrically connected, and the dual-color indicator light 5 and the second proximity switch 6 are electrically connected. When the photovoltaic panel adjustment frame 2 rotates from the windproof state to the working state, the first proximity switch 4 is triggered. When the photovoltaic panel adjustment frame 2 rotates from the working state to the windproof state, the second proximity switch 6 is triggered. When the first proximity switch 4 or the second proximity switch 6 is not triggered by the photovoltaic panel adjustment frame 2, the dual-color indicator light 5 does not light up.

[0068] The dual-color indicator light 5, with its red and green dual-color light function and the function of not lighting up when not triggered by the first proximity switch 4 or the second proximity switch 6, allows manual inspections to intuitively detect whether the photovoltaic panel adjustment frame 2 is not adjusted to the predetermined position or whether there are malfunctions such as jamming or thrust failure in the operating parts of the windproof device. This effectively improves the efficiency and accuracy of daily inspections.

[0069] For example, if the dual-color indicator light 5 does not light up several minutes (e.g., 5 or 10 minutes) after the first proximity switch 4 sends a signal, it proves that the photovoltaic panel adjustment frame 2 has not been adjusted to the working state and the windproof device has a malfunction.

[0070] like Figure 1 As shown, optionally, the second proximity switch 6 is located on the top rear side of the frame 1, and the dual-color indicator light 5 is located on the top rear side of the frame 1. This arrangement can shorten the distance between the dual-color indicator light 5 and the second proximity switch 6, reduce the length of the wires connecting the dual-color indicator light 5 and the second proximity switch 6, and facilitate the electrical connection between the dual-color indicator light 5 and the second proximity switch 6.

[0071] Please also refer to Figure 1 , Figure 3 and Figure 4 The wind protection device of the photovoltaic power generation structure may also include a wind speed sensor 8 and a controller 9. The controller 9 can be electrically connected to the wind speed sensor 8, the telescopic component 3, the first proximity switch 4, the second proximity switch 6, the third proximity switch 7 and the dual-color indicator light 5 via wires.

[0072] The working principle of the windproof device is as follows:

[0073] Please also refer to Figure 1 and Figure 4 When the photovoltaic panel adjustment frame 2 is in operation, if the wind speed sensor 8 detects a strong wind (for example, when the wind speed sensor 8 detects a wind speed of level 6), the controller 9 will send an action command to the telescopic component 3 according to the set wind speed alarm level parameters. The telescopic component 3 will then extend, causing the photovoltaic panel adjustment frame 2 to rotate counterclockwise (rotation direction as shown in the image). Figure 1 As shown by the curved arrow in the diagram, the photovoltaic panel adjustment frame 2 is adjusted to a windproof state to reduce its windward area and resist the destructive force of strong winds on the photovoltaic structure. When the photovoltaic panel adjustment frame 2 is adjusted to a windproof state, the second proximity switch 6 is turned on, and the controller 9 generates a command to turn the dual-color indicator light 5 red based on the signal from the second proximity switch 6, causing the dual-color indicator light 5 to illuminate red.

[0074] If the photovoltaic panel adjustment frame 2 does not trigger the second proximity switch 6 within a predetermined time (e.g., 5 minutes or 10 minutes) after rotating counterclockwise, the dual-color indicator light 5 will not light up, indicating that the windproof device has malfunctioned.

[0075] Please also refer to Figure 3 and Figure 4 When the wind speed sensor 8 detects a wind speed lower than the alarm level (for example, when the wind speed sensor 8 detects a wind speed lower than level 6 gale), the controller 9 will send an action command to the telescopic component 3, and the telescopic component 3 will immediately retract (the retraction direction is as follows). Figure 3 (As shown by the straight arrow in the image), causing the photovoltaic panel adjustment frame 2 to rotate clockwise (rotation direction as shown in the image). Figure 3 As shown by the curved arrow in the image, adjust the photovoltaic panel adjustment frame 2 to the working state. Figure 1 As shown, when the photovoltaic panel adjustment frame 2 is adjusted to the working state, the first proximity switch 4 and the third proximity switch 7 are turned on (please refer to the third proximity switch 7). Figure 2 The controller 9 generates a command to turn the dual-color indicator light 5 green based on the connection signals of the first proximity switch 4 and the third proximity switch 7, so that the dual-color indicator light 5 lights up green. At this time, the photovoltaic panel of the photovoltaic panel adjustment frame 2 can resume normal power generation operation.

[0076] If the photovoltaic panel adjustment frame 2 does not trigger the first proximity switch 4 within a predetermined time (e.g., 5 minutes or 10 minutes) after rotating clockwise, the dual-color indicator light 5 will not light up, indicating that the windproof device has malfunctioned.

[0077] The windproof device for the photovoltaic power generation structure provided in the embodiments of this application has been described in detail above. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be construed as a limitation of this application. All equivalent modifications or changes made in accordance with the spirit and technical concept of this application should still be covered by the claims of this application.
