Description

Technical Field

[0001] The present application belongs to the field of photovoltaic panel technology, and specifically relates to a photovoltaic system integrating snow and ice removal and monitoring functions. Background Art

[0002] As global demand for clean energy continues to grow, photovoltaic power generation, as a green and sustainable energy source, is gradually expanding its application scenarios to extreme environments such as high altitudes and polar regions. However, in these regions with frequent cold temperatures and heavy snowfall, photovoltaic systems face severe operational challenges. The continuous accumulation of snow and ice significantly reduces the light transmittance and power generation efficiency of photovoltaic panels. According to statistics, a snow cover as thin as 5mm can reduce the power generation efficiency of photovoltaic panels by 15%-20%. Ice not only blocks light absorption but also causes structural damage to photovoltaic panels due to stress caused by alternating cold and hot conditions.

[0003] Currently, snow and ice removal technologies on the market primarily include manual sweeping, mechanical scraping, and heated snowmelt. Manual sweeping is inefficient and poses safety risks in extreme environments. Mechanical scraping can easily cause physical damage to the surface of photovoltaic panels, shortening the equipment's lifespan. While heated snowmelt can be automated, it consumes too much energy and has limited de-icing effectiveness in persistently low temperatures. Summary of the Invention

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0024] like Figures 1 to 2 As shown, the embodiment of the present application provides a photovoltaic system integrating snow and ice removal and monitoring functions, including: Photovoltaic panels 11; A snow removal module is provided on the sunny side of the photovoltaic panel 11; The electromagnetic deicing module 13 is arranged on the shady side of the photovoltaic panel 11; An environmental monitoring module is provided on the photovoltaic panel 11 and is used to collect data on the ice and snow coverage status of the photovoltaic panel 11; The central control module 15 is arranged on the shady side of the photovoltaic panel 11. The snow removal module, the electromagnetic deicing module 13 and the environmental monitoring module are all electrically connected to the central control module 15. The central control module 15 is used to analyze the ice and snow coverage status data and control the snow removal module and the electromagnetic deicing module 13 to work according to the analysis results.

[0025] According to the photovoltaic system that integrates snow removal, ice removal and monitoring functions provided in the embodiment of the present application, the photovoltaic panel 11, as the core of energy conversion, directly receives sunlight to generate electricity; a snow removal module is provided on its sunny side, which can effectively remove snow, ensure that the surface of the photovoltaic panel 11 remains clean, and maximize the light receiving area. An electromagnetic deicing module 13 is installed on the shady side, which uses the specific frequency and intensity generated by electromagnetic vibration to effectively remove the ice layer and prevent structural damage caused by alternating hot and cold temperatures. At the same time, the environmental monitoring module can monitor the ice and snow coverage on the surface of the photovoltaic panel 11 in real time and feed the data back to the central control module 15. The central control module 15 plays the role of "brain". It not only analyzes and processes the collected data, but also intelligently adjusts the working status of the snow removal module and the electromagnetic deicing module 13 according to the results to ensure the efficient operation of the system.

[0026] The system operates by detecting snow or ice accumulation on the surface of the photovoltaic panels 11. When the environmental monitoring module detects snow or ice, it immediately triggers the central control module 15 to analyze the data and initiate appropriate snow or ice removal operations. For example, when snow accumulation reaches a certain thickness, the central control module 15 activates the snow removal module; if ice is detected, the electromagnetic de-icing module 13 is activated to remove the ice through vibration. This intelligent design enables the system to respond promptly to various environmental changes, significantly improving the efficiency and safety of photovoltaic power generation, reducing the need for manual intervention, and lowering maintenance costs.

[0027] like Figure 1 As shown, in some embodiments of the present application, the snow removal module includes a snow removal bar 121, a roller 122 and a wheel track 123; The snow removal bar 121 is connected to the wheel rail 123 in a rolling manner via the roller 122 .

[0028] The snow removal bar 121 is the part that directly contacts the accumulated snow and performs the clearing task. The snow removal bar 121 is usually made of low-temperature resistant materials to ensure that it can still maintain good mechanical properties under extreme cold conditions.

[0029] Rollers 122 are mounted below the snowplow bar 121, supporting it and enabling it to glide smoothly on the wheel rails 123. The number and layout of rollers 122 ensure that the snowplow bar 121 applies force evenly during movement, preventing damage to the photovoltaic panels 11 from excessive localized pressure. Rollers 122 also exhibit excellent wear resistance and a low coefficient of friction, ensuring smooth operation in low-temperature environments.

[0030] The wheel rail 123 provides a track for the roller 122. Its stability and durability ensure its structural integrity even in adverse weather conditions such as strong winds and heavy snow, allowing the snowplow bar 121 to successfully complete its snow removal tasks. The wheel rail 123 is typically fixed to the frame of the photovoltaic panel 11, ensuring a suitable distance from the surface of the photovoltaic panel 11 to avoid affecting the panel's operating efficiency.

[0031] The snowplow bar 121 is connected to the wheel track 123 via rollers 122, forming a highly efficient mechanical transmission mechanism. When the environmental monitoring module detects a certain level of snow accumulation on the surface of the photovoltaic panel 11, the central control module 15 issues a command to initiate snow removal. At this point, the snowplow bar 121, driven by a motor, moves along the wheel track 123. The rollers 122 roll within the wheel track 123, driving the snowplow bar 121 forward or backward, thereby removing the accumulated snow from the surface of the photovoltaic panel 11.

[0032] In addition, in order to further optimize the snow removal effect, the snow removal bar 121 can also be equipped with auxiliary equipment such as a wide-angle camera to monitor the surface condition of the photovoltaic panel 11 in real time, helping the system to more accurately determine when to start the snow removal operation and adjust the working path and speed of the snow removal bar 121, thereby achieving more intelligent and efficient snow removal operations.

[0033] In some embodiments of the present application, the length of the snow removal bar 121 is not less than the length of the photovoltaic panel 11; The wheel rail 123 extends along the width direction of the photovoltaic panel 11 , and the length of the wheel rail 123 is not less than the width of the photovoltaic panel 11 .

[0034] Because the design length of wheel track 123 is no less than the width of photovoltaic panel 11, and the length of snow removal bar 121 is no less than the length of photovoltaic panel 11, snow removal bar 121 can cover the entire surface of photovoltaic panel 11, ensuring that snow is thoroughly cleared. Snow removal bar 121 is equal to or greater than the length of photovoltaic panel 11, ensuring that snow can be effectively removed even at the very edge of photovoltaic panel 11, preventing the reduction of light receiving area due to localized snow accumulation.

[0035] like Figure 2 As shown, in some embodiments of the present application, the electromagnetic deicing module 13 includes a support frame 131 and an electromagnetic vibration unit, and the electromagnetic vibration unit is embedded in the support frame 131; The support frame 131 is attached to the shady side of the photovoltaic panel 11 .

[0036] The support frame 131 is a crucial component of the electromagnetic de-icing module 13. It not only provides a stable mounting base for the electromagnetic vibration unit but also ensures that electromagnetic vibrations are efficiently transmitted to the surface of the photovoltaic panel 11. The support frame 131 is bolted to the underside of the photovoltaic panel 11 and maintains a close fit, ensuring structural stability and reliability. To achieve optimal vibration transmission, the support frame 131 is typically constructed from high-strength, lightweight materials, ensuring sufficient rigidity without placing excessive burden on the photovoltaic panel 11. The electromagnetic vibration unit, embedded within the support frame 131, is the core component that enables the de-icing function. It utilizes electromagnetic force to generate vibrations of a specific frequency and intensity. This vibration is effectively transmitted through the support frame 131 to the surface of the photovoltaic panel 11, thereby breaking the adhesion between the accumulated ice and the panel 11 surface and causing the ice to fall off. The design of the electromagnetic vibration unit requires precise calculation of the vibration frequency and amplitude to effectively remove ice without damaging the photovoltaic panel 11 itself.

[0037] When the environmental monitoring module detects ice on the surface of the photovoltaic panel 11, the central control module 15 initiates the electromagnetic de-icing process. The electromagnetic vibration unit then activates, generating vibrations of a specific frequency and intensity. These vibrations are efficiently transmitted to the surface of the photovoltaic panel 11 via the support frame 131, causing the ice to loosen and eventually fall off the panel 11.

[0038] Through the above mechanism, electromagnetic deicing module 13 can achieve efficient deicing without using additional heat energy, saving energy while also reducing other potential problems caused by heating (such as material fatigue caused by temperature changes). Furthermore, electromagnetic deicing avoids surface scratches or damage that can occur with mechanical scraping, thereby extending the service life of photovoltaic panels 11.

[0039] like Figure 2 As shown, in some embodiments of the present application, at least two support frames 131 are provided, and the support frames 131 are evenly distributed on the shady side of the photovoltaic panel 11; The number of the supporting frames 131 is not less than the number of the electromagnetic vibration units.

[0040] The design of the support frame 131 takes into account the factors of uniform distribution and maximizing vibration efficiency. Therefore, at least two support frames 131 are set on the shady side of the photovoltaic panel 11, and these support frames 131 are evenly distributed on the back of the entire photovoltaic panel 11 to ensure that the vibration energy can act evenly on the entire surface of the photovoltaic panel 11, avoiding local stress concentration or insufficient vibration.

[0041] The support frame 131 reserves installation space for the electromagnetic vibration units, and the number of electromagnetic vibration units can be adjusted according to actual needs.

[0042] like Figures 1 to 2 As shown, in some embodiments of the present application, the environment monitoring module includes an image collector 141, a temperature sensor 142 and a pressure sensor 143; The image collector 141 is arranged on the top of the sunny side of the photovoltaic panel 11 and is suitable for collecting images of ice and snow covering the sunny side; The temperature sensor 142 is disposed on the shady side of the photovoltaic panel 11 and is suitable for collecting the ambient temperature and the surface temperature of the photovoltaic panel 11; The pressure sensor 143 is disposed in the middle of the shady side of the photovoltaic panel 11 and is suitable for collecting the pressure on the panel surface of the photovoltaic panel 11 .

[0043] Image collector 141 is located on the sun-facing surface of photovoltaic panel 11 and is used to monitor the snow and ice coverage of the panel 11 in real time. Its primary function is to capture visual information of the panel 11 surface, enabling the system to identify the presence and extent of snow or ice. Image collector 141 typically uses a wide-angle camera to capture the largest possible area, providing a comprehensive understanding of the panel 11 surface condition.

[0044] Positioning image collector 141 on top of the sun-facing side of photovoltaic panel 11 ensures an optimal viewing angle, avoids obstruction by snow, and enables clear and accurate images to be obtained. Image collector 141 can be equipped with image processing software that automatically analyzes captured images and determines the specific conditions of snow and ice, such as thickness and distribution.

[0045] Temperature sensor 142 is mounted on the shaded side of photovoltaic panel 11 to measure both the ambient temperature and the panel's surface temperature. This helps assess the risk of freezing, as water freezes to form ice when temperatures fall below zero. Placing the sensor on the shaded side reduces the impact of direct sunlight on temperature readings, providing more accurate ambient temperature data.

[0046] Pressure sensor 143 is also located in the middle of the shady side of photovoltaic panel 11 to detect pressure changes on the panel 11 caused by accumulated snow or ice. This is crucial for assessing the weight of the snow or ice, as excessive pressure could damage the panel 11 structure. The central location better reflects the overall pressure distribution, avoiding misjudgments caused by localized pressure imbalances. By monitoring pressure changes, the thickness and distribution of the snow or ice can be indirectly inferred, providing a basis for snow or ice removal operations.

[0047] Working principle: The environmental monitoring module works in conjunction with the image collector 141 , the temperature sensor 142 and the pressure sensor 143 to collect data related to the surface status of the photovoltaic panel 11 in real time, and transmits the data to the central control module 15 for analysis and processing.

[0048] Image acquisition and analysis: Image collector 141 continuously captures images of the sun-facing side of photovoltaic panels 11 and uses image processing algorithms to analyze the extent and thickness of snow or ice. If an abnormality (such as large areas of snow accumulation) is detected, central control module 15 is immediately notified to initiate snow removal.

[0049] Temperature monitoring and warning: The temperature sensor 142 continuously monitors the ambient temperature and the surface temperature of the photovoltaic panel 11. When the temperature approaches or drops below zero degrees, the system will issue an ice warning signal, prompting the need to activate the electromagnetic deicing module 13 to prevent ice formation.

[0050] Pressure Sensing and Response: Pressure sensor 143 detects changes in pressure on the surface of photovoltaic panel 11. If the detected pressure exceeds a preset threshold, it indicates that the accumulated snow or ice has reached a certain weight and requires removal. Central control module 15 then determines whether to initiate snow or ice removal based on the information provided by pressure sensor 143.

[0051] The central control module 15 aggregates data from the image collector 141, temperature sensor 142, and pressure sensor 143, and makes decisions based on intelligent analysis. For example, if heavy snow accumulation is confirmed, the snow plow 121 is activated to clear the snow; if ice is detected, the electromagnetic vibration unit is activated to remove ice.

[0052] like Figure 2 As shown, in some embodiments of the present application, at least two temperature sensors 142 are provided; The temperature sensors 142 are evenly distributed on the shady side of the photovoltaic panel 11 .

[0053] By evenly distributing multiple temperature sensors 142 on the shady side of the photovoltaic panel 11, it is possible to more accurately capture temperature variations in different areas of the photovoltaic panel 11. This helps identify local temperature differences, especially on large-area photovoltaic panels 11, where temperature differences may exist in different areas due to factors such as uneven lighting and wind direction.

[0054] A single temperature sensor 142 may not fully reflect the temperature conditions of the entire photovoltaic panel 11, especially in extreme environments where localized ice formation or snow melting may lead to uneven temperature distribution. Multiple temperature sensors 142 provide more comprehensive and accurate data, enabling the central control module 15 to make more accurate decisions.

[0055] The system reliability is also increased by providing multiple temperature sensors 142 at key locations. If one of the sensors fails, the other sensors can still continue to work, ensuring that the system will not fail due to a single point of failure.

[0056] The primary function of the temperature sensors 142 is to monitor ambient temperature and temperature changes on the surface of the photovoltaic panels 11, providing data support to the central control module 15 to help determine whether there is a risk of icing or abnormal temperature rise. Each temperature sensor 142 continuously collects temperature information at its location and transmits this data to the central control module 15 in real time. Through multi-point measurement, the system can obtain temperature distribution maps for different areas on the surface of the photovoltaic panels 11, thereby better understanding the current environmental conditions and their impact on the photovoltaic panels 11. After receiving data from all temperature sensors 142, the central control module 15 conducts a comprehensive analysis. For example, in cold winter conditions, if multiple temperature sensors 142 simultaneously report temperatures below freezing, this indicates a risk of icing. In this case, the system may activate the electromagnetic deicing module 13 for preventive deicing operations. Conversely, if the temperature in some areas is significantly higher than in other areas, it may be due to the melting of local snow or other abnormal conditions, requiring further inspection or appropriate measures.

[0057] In some embodiments of the present application, the central control module 15 includes a control unit and a power supply unit; The control unit is adapted to control the operation of the snow removal module and the electromagnetic deicing module 13; The power supply unit is suitable for supplying power to the snow removal module, the electromagnetic deicing module 13 and the environment monitoring module.

[0058] As the core part of the central control module 15, the control unit is responsible for receiving data from the environmental monitoring module and processing and analyzing this data. Based on the analysis results, the control unit can intelligently issue instructions to start or stop the snow removal module and electromagnetic deicing module 13. Specifically: The control unit analyzes the data provided by the temperature sensor 142, the pressure sensor 143 and the image collector 141 through a built-in algorithm to determine whether there is snow or ice on the surface of the photovoltaic panel 11 and the severity of the snow or ice.

[0059] Once it determines that an action is needed (such as snow or ice removal), the control unit sends precise control instructions to the corresponding execution module. For example, it can adjust the speed and direction of the snow removal bar 121 according to the thickness of the snow, or adjust the frequency and intensity of the electromagnetic vibration unit according to the thickness of the ice layer.

[0060] The power supply unit is a key component to ensure the stable operation of the entire system. It not only provides power support for the control unit itself, but is also responsible for supplying power to the snow removal module, electromagnetic deicing module 13 and environmental monitoring module.

[0061] Power supply units typically use efficient power management systems that optimize energy distribution under varying weather conditions, ensuring that critical systems remain operational even in low-light conditions.

[0062] To improve system reliability, the power supply unit may include a backup power supply or battery pack to ensure that the basic functions of the system are not affected in the event of a main power failure.

[0063] In some embodiments of the present application, the surface of the photovoltaic panel 11 is provided with a hydrophobic coating; The thickness of the hydrophobic coating is 5 microns to 50 microns.

[0064] The hydrophobic coating applied to the surface of the photovoltaic panel 11 is primarily intended to reduce the adhesion of ice and snow to the panel 11, thereby improving the power generation efficiency of the photovoltaic system. The hydrophobic coating modifies the physical properties of the panel 11 surface, giving it a lower surface energy. This prevents water droplets and other liquids from adhering to the surface, instead forming spherical droplets that roll off.

[0065] The thickness of the hydrophobic coating is set to be between 5 microns and 50 microns. This thickness range ensures that the coating has sufficient hydrophobicity, but does not affect the optical performance of the photovoltaic panel 11 or add extra weight due to excessive thickness.

[0066] Hydrophobic coatings are typically made of materials with low surface energy properties, such as fluorinated polymers and silicones. These materials not only provide good hydrophobicity but also possess certain weather resistance and UV resistance, ensuring stability for long-term outdoor use.

[0067] In some embodiments of the present application, drainage grooves and diversion channels are formed on the sun-facing side of the photovoltaic panel 11; Drainage grooves are arranged along the edges of the photovoltaic panels 11 to collect melted ice water during snow and ice removal; The diversion channel is communicated with the drainage groove and is suitable for guiding the melted ice water to the external area of ​​the photovoltaic system.

[0068] The drainage trough and the diversion channel work together to effectively manage the melted ice and snow water on the surface of the photovoltaic panel 11, preventing the impact of water accumulation on the photovoltaic system. The specific working process is as follows: When the photovoltaic system performs snow or ice removal operations (e.g., through vibrations generated by the electromagnetic vibration unit), the snow or ice begins to melt, forming liquid water. This water needs to be removed promptly, otherwise it may refreeze into ice or make the surface of the photovoltaic panel 11 slippery, affecting subsequent operations.

[0069] As temperatures rise or due to external heating, snow and ice gradually melt into water. This water naturally flows along the sloped surface of the photovoltaic panel 11, ultimately collecting in the drainage grooves at the edge. Because the drainage grooves are arranged along the edge of the photovoltaic panel 11, they effectively intercept and collect all water flowing towards the edge.

[0070] Melted ice collected in the gutter is channeled through a connected diversion channel to the exterior of the PV system. The design of the diversion channel ensures smooth and rapid drainage, preventing water from accumulating on the surface of the PV panels 11 or within the system. This not only prevents secondary freezing but also reduces the potential damage caused by accumulated water.

[0071] Through an effective drainage mechanism, the photovoltaic system can quickly return to optimal condition after snow or ice removal, maintaining high energy conversion efficiency. In addition, this design also helps extend the service life of photovoltaic panels 11 and other components by reducing corrosion or other forms of physical damage caused by long-term contact with water.

[0072] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0074] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included in the protection scope of the present application.
