Description
Technical Field
[0001] This invention relates to the field of photovoltaics, and in particular to a solar panel protection device and system. Background Technology
[0002] Currently, photovoltaic (PV) power generation systems are widely used to power outdoor monitoring systems, and in many scenarios, they are the sole power source for monitoring equipment. Most existing PV installations are installed outdoors in an exposed manner, with the solar panels exposed to the elements 365 days a year. While this exposed installation is low-cost, long-term use leads to two consequences: First, prolonged exposure to dust can accumulate on the surface of the solar panels. In rainy or humid weather, this dust can turn into mud and condense on the surface. Even rain cannot completely remove the dirt, and over time, this layer of dirt significantly reduces the solar panels' energy efficiency. Second, they are susceptible to bird damage. Birds standing on the solar panels can reduce their power generation efficiency, and their droppings not only contaminate the surface but also cause overheating and damage to the surface material. The corrosion of materials severely affects the lifespan and performance of solar panels; thirdly, in some special applications in special areas, such as icing monitoring systems for power transmission lines in mountainous areas, when rain or snow occurs in winter, an ice layer will form on the surface of solar photovoltaic panels, causing them to lose their ability to obtain light energy. Even if there is a brief sunny day, due to the low air temperature, the ice layer on the solar panels is difficult to completely melt and cannot restore the power-gathering function. At night, the partially melted ice layer will refreeze, which can cause the solar panels to be unable to work effectively for a long time. This will cause the energy storage system of the monitoring equipment to be unable to draw power effectively for a long time, causing the equipment to enter a power-out state, requiring manual intervention to restore the system's operation.
[0003] Therefore, these specialized applications require maximizing the efficiency of solar panels, necessitating special maintenance of the panel surface to ensure their ability to capture sunlight in outdoor environments. However, such equipment is typically installed in remote locations, making it difficult for maintenance personnel to access the site. Therefore, an automated method for maintaining and servicing solar panels is needed. Summary of the Invention
[0004] Therefore, the technical problem to be solved by the present invention is: how to maintain the surface of a solar panel so that the solar panel can maintain its ability to acquire light energy in an outdoor environment.

[0008] In a preferred embodiment of the solar panel protection device of the present invention: a protective door is provided on the side wall of the protective shell, and one end of the protective door is rotatably connected to the side wall of the protective shell through a connector.
[0009] In a preferred embodiment of the solar panel protection device of the present invention: the control component includes a controller, a first position sensor electrically connected to the controller, and a second position sensor electrically connected to the controller; the first position sensor and the second position sensor are both disposed on the inner wall of the protective shell, and the first position sensor and the second position sensor are respectively used to limit the head end and the tail end of the moving component.
[0010] In a preferred embodiment of the solar panel protection device of the present invention: the cleaning component includes a connecting rod disposed on the inner wall of the protective shell and a cleaning brush disposed on the connecting rod; the end of the cleaning brush away from the inner wall of the protective shell can fit against the end of the solar panel.
[0011] In a preferred embodiment of the solar panel protection device of the present invention: the moving part includes a support plate and a moving wheel connected to the support plate; the end of the support plate is used to place the solar panel, and the motor can drive the moving wheel to move.
[0012] In a preferred embodiment of the solar panel protection device of the present invention: the limiting member includes a moving track, the moving wheel is able to move in and out of the receiving space along the moving track, and the moving track is used to limit the movement trajectory of the moving wheel.
[0013] In a preferred embodiment of the solar panel protection device of the present invention: the limiting member includes a telescopic rod, one end of which is connected to the inner wall of the protective shell, and the other end of which is connected to the bearing plate; when the moving wheel moves, it drives the length of the telescopic rod to change synchronously, and the telescopic rod is used to limit the moving trajectory and the maximum moving distance of the moving wheel.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0027] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.
[0028] Reference Figure 1-Figure 5 This embodiment provides a solar panel protection device, including a protective shell 1, with an inner wall forming a receiving space 11. A motor 2 and a control component 3 connected to the motor 2 are disposed within the receiving space 11. A solar panel 4 can be moved to the inner wall of the receiving space 11 via a moving component 5. The protective shell 1 is used to protect the solar panel 4. The control component 3 can control the opening and closing state of the motor 2 according to environmental changes. When the motor 2 is started, it can drive the solar panel 4 into and out of the receiving space 11 via the moving component 5. The solar panel 4 changes its position relative to the receiving space 11 by sensing environmental changes through the control component 3, so that the solar panel 4 can maintain its ability to obtain light energy.
[0029] In the current technology, most photovoltaic power generation devices adopt outdoor exposed installation. Although this type of installation has a lower cost, the long-term maintenance cost is high. Moreover, such devices are mostly installed in remote places, making it very difficult for maintenance personnel to reach the site.
[0030] Our invention employs a protective shell 1 and a control unit 3 in conjunction. When the external sunlight intensity is higher than a set value, the control unit 3, via motor 2, controls the moving part 5 to move the solar panel 4 out of the protective shell 1; when the external sunlight intensity is lower than the set value, the control unit 3, via motor 2, controls the moving part 5 to move the solar panel 4 into the protective shell 1. This design allows the solar photovoltaic panel 4 to be retracted into the protective shell 1 during rainy, snowy weather and at sunset, thus preventing ice from covering the photovoltaic panel surface and protecting the photovoltaic surface from dust.
[0031] In some implementations, refer to Figure 1 The space 11 contains a cleaning component for cleaning the surface of the solar panel 4. The position of the solar panel 4 changes as the moving component 5 moves, allowing the cleaning component to contact different positions on the surface of the solar panel 4, thereby cleaning the surface of the solar panel 4.
[0032] By incorporating cleaning components, the surface of the solar panel 4 can be cleaned synchronously as it moves, thereby maintaining the cleanliness of the solar panel 4 surface and automating its cleaning and maintenance.
[0033] When the moving part 5 moves the solar panel 4, the position of the solar panel 4 will change accordingly. This change in position allows the cleaning part to smoothly contact different parts of the surface of the solar panel 4.
[0034] By incorporating a cleaning component, the surface of the solar panel 4 is cleaned simultaneously during its movement, ensuring that the surface remains consistently clean. This automation automates the cleaning and maintenance of the solar panel 4, significantly reducing the need for manual intervention and improving its efficiency and lifespan.
[0035] Specifically, refer to Figure 1 A limiting member 7 is provided within the accommodating space 11. One end of the limiting member 7 is connected to the accommodating space 11, and the other end is connected to the moving member 5. The function of the limiting member 7 is to restrict the moving distance and the moving track 71 of the moving member 5, so that the solar panel 4 can enter and exit the accommodating space 11 along a predetermined trajectory.
[0036] Furthermore, refer to Figure 1-Figure 5The protective shell 1 has a protective door 12 on its side wall. One end of the protective door 12 is rotatably connected to the side wall of the protective shell 1 through a connector. When the solar panel 4 is completely moved into the receiving space 11, the protective door 12 no longer contacts the solar panel 4. At this time, the protective door 12 is closed, making the inner wall of the protective shell 1 a closed space.
[0037] When the solar panel 4 moves outside the housing space 11, the protective door 12 is always in contact with the surface of the solar panel 4. This arrangement ensures that the solar panel 4 will not be blocked by the protective door 12 when it moves towards the inner wall of the housing space 11.
[0038] It should also be noted that the protective door 12 can be made of aluminum alloy, and a transparent window 13 is provided at the top of the protective shell 1. The controller 31 can collect the external ultraviolet light value through the transparent window 13.
[0039] Furthermore, refer to Figure 1 and Figure 6 The control component 3 includes a controller 31, a first position sensor 32 electrically connected to the controller 31, and a second position sensor 33 electrically connected to the controller 31. The first position sensor 32 and the second position sensor 33 are both disposed on the inner wall of the protective shell 1. The first position sensor 32 and the second position sensor 33 are respectively used to limit the head end and the tail end of the moving component 5.
[0040] It should be noted that the controller 31 typically includes an ultraviolet light sensor, a temperature sensor, and a humidity sensor. The ultraviolet light sensor detects the sunlight conditions on the outer wall. If the ultraviolet light intensity is lower than a set value, it indicates that the external weather may be cloudy or rainy, or that the sun has already set. In this case, the controller 31 controls the rotation of the motor 2 to return the moving part 5, which is equipped with the solar panel 4, back into the protective shell 1. The controller also uses the first position sensor 32 and the second position sensor 33, which are installed inside the upper part of the protective shell 1, to detect the position of the trolley. When the moving part 5 enters and exits the protective shell 1, the cleaning brush 6, installed near the protective door 12 at the upper part of the protective shell 1, sweeps away the dust on the surface of the photovoltaic panel, thus keeping the surface of the photovoltaic panel clean for a long time.
[0041] When the ultraviolet sensor and temperature sensor work together to detect the possibility of snow or freezing, the ultraviolet light sensor controls the motor 2 to start the moving part 5, which drives the solar panel 4 to automatically retract into the protective shell 1. It should be noted that the motor 2 used in this embodiment is preferably a dual coaxial DC servo motor 2.
[0042] like Figure 6As shown, the controller 31 uses the values of the ultraviolet sensor, temperature sensor and humidity sensor to determine the external environment, uses the values of the first position signal sensor and the second position signal sensor to determine the position of the trolley, and controls the forward and reverse rotation of the motor 2 to realize the extension and retraction of the photovoltaic panel trolley.
[0043] Specifically, by sensing changes in the external environment through temperature, humidity, and light sensors installed on it, the controller 31 will control the movable photovoltaic panel to retract its protective cover when one of the following conditions occurs, thereby preventing rain and snow from covering the photovoltaic panel surface: ultraviolet radiation is below a set value, humidity is above a set value, or temperature is below a set value.
[0044] Among them, ultraviolet intensity control has the highest priority. Humidity and temperature control are determined in controller 31 according to different system times. For example, in winter, the temperature detection criterion will be increased, while at other times, the humidity criterion will be increased.
[0045] Furthermore, the cleaning component includes a connecting rod disposed on the inner wall of the protective shell 1 and a cleaning brush 6 disposed on the connecting rod; the end of the cleaning brush 6 away from the inner wall of the protective shell 1 can fit against the end of the solar panel 4. When the solar panel 4 is carried in and out of the receiving space 11 by the moving component 5, the cleaning brush 6 installed on the top of the side wall of the protective shell 1 will clean the dust on the surface of the solar panel 4, thereby keeping the surface of the solar panel 4 clean for a long time.
[0046] Furthermore, the moving part 5 includes a support plate 51 and a moving wheel 52 connected to the support plate 51; the end of the support plate 51 is used to place the solar panel 4, and the motor 2 can drive the moving wheel 52 to move.
[0047] Furthermore, the limiting member 7 includes a moving track 71, along which the moving wheel 52 can enter and exit the receiving space 11. The moving track 71 is used to limit the movement trajectory of the moving wheel 52.
[0048] As an optional embodiment, the limiting member 7 includes a telescopic rod, one end of which is connected to the inner wall of the protective shell 1, and the other end of which is connected to the bearing plate 51; when the moving wheel 52 moves, it drives the length of the telescopic rod to change synchronously, and the telescopic rod is used to limit the moving trajectory and the maximum moving distance of the moving wheel 52.
[0049] Furthermore, the connector includes a torsion spring, and one end of the protective door 12 is rotatably connected to the side wall of the protective shell 1 via the torsion spring; when the solar panel 4 is moved out of the receiving space 11, the end of the protective door 12 away from the torsion spring contacts the end of the solar panel 4.
[0050] It should be noted that a one-way inward spring, typically a torsion spring, can be used at the end of the protective door 12 and on the housing of the protective shell 1, so that the protective door 12 remains closed when no external force is applied. When the moving part 5 moves out, the motor 2 drives the moving part 5 to push the protective door 12 open. As the trolley is fully retracted, the protective door 12 automatically closes under the action of the torsion spring.
[0051] As an optional embodiment, the connector can also be a hinge, with one end of the protective door 12 rotatably connected to the side wall of the protective shell 1 via the hinge; when the solar panel 4 is moved out of the receiving space 11, the end of the protective door 12 away from the hinge contacts the end of the solar panel 4.
[0052] Reference Figures 6-7 This embodiment provides a solar panel protection system, a control module 100, including a controller 31, a first position sensor 32, and a second position sensor 33;
[0053] An environmental monitoring module 200 is electrically connected to the control module and is used to collect external environmental data in real time. The environmental data includes at least ultraviolet intensity, temperature and humidity.
[0054] The data processing module 300 is communicatively connected to the environmental monitoring module 200 and the control module 100. It is used to analyze the environmental data according to a preset threshold and generate control commands to be transmitted to the control module 100 to trigger the motor 2 to drive the moving part 5 to perform corresponding actions.
[0055] It should be noted that the environmental monitoring module 200 is designed to collect multi-dimensional data on the external environment in real time. This environmental data not only covers the key indicator of ultraviolet radiation intensity, but also includes important parameters such as temperature and humidity, enabling a comprehensive perception of environmental changes.
[0056] The data processing module 300 establishes stable communication connections with both the control module 100 and the environmental monitoring module 200, enabling it to perform in-depth analysis and evaluation of environmental data based on pre-set thresholds. If the analysis results indicate that environmental parameters exceed safe limits, the data processing module 300 immediately generates corresponding control commands and rapidly transmits them to the control module 100. Upon receiving the commands, the control module 100 triggers the motor 2 to start, thereby driving the moving component 5 to perform corresponding protective actions, ensuring effective protection of the solar panels under various environmental conditions.
[0057] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
