Description

Technical Field

[0002] With the rapid development of photovoltaic power generation technology, the scale of photovoltaic power stations has gradually expanded. As a key support structure for photovoltaic panels, the stability and safety of photovoltaic brackets directly affect the efficiency and safety of photovoltaic power generation. Currently, in the field of solar photovoltaic power generation, solar photovoltaic panels with automatic tracking functions have been developed, ensuring that the panels are always oriented in the direction of sunlight, thereby increasing power generation. However, existing solar photovoltaic panels with automatic tracking functions have some problems. For example, in strong winds, the photovoltaic brackets may vibrate violently, even causing the panels to be blown over.

[0003] Furthermore, the current inspection of photovoltaic brackets relies mainly on manual inspections, which suffer from low inspection efficiency and the inability to monitor in real time. Therefore, a solution that can monitor the status of photovoltaic brackets in real time is urgently needed to improve the operational safety and maintenance efficiency of photovoltaic power plants.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1 and Figure 2As shown, the utility model provides a photovoltaic tracking bracket based on sensor technology, including a photovoltaic panel assembly 1, a bracket body, a motor 2, a control module and a sensor module; the bracket body is used to support the photovoltaic panel assembly 1, and the bracket body includes a main beam 3 that runs across the middle of the photovoltaic panel assembly 1; the motor 2 is used to control the rotation of the main beam 3, thereby driving the photovoltaic panel assembly 1 to rotate as a whole; the sensor module includes a number of photosensors 4, a vibration sensor 5 and a tilt sensor; the photosensor 4 is installed on the surface of the photovoltaic panel assembly 1, and is used to collect current light angle data; the vibration sensor 5 is installed on the main beam 3, and is used to collect current vibration data; the tilt sensor is installed on the back of the photovoltaic panel assembly 1, and is used to collect current tilt angle data; the control module is electrically connected to the motor 2 and each sensor in the sensor module respectively.

[0023] Preferably, the sensor module further includes a plurality of temperature sensors, which are mounted on the back of the photovoltaic panel assembly 1 and in contact with the photoelectric conversion material, and are used to collect operating temperature data of the photovoltaic panel assembly 1 .

[0024] Preferably, the sensor module further includes a plurality of stress sensors, which are installed on the back of the photovoltaic panel assembly 1 and are used to collect stress and deformation data of the photovoltaic panel assembly 1 .

[0025] Preferably, the vibration sensor 5 is an acceleration sensor, which is used to detect the acceleration change of the main beam 3 in real time and output a vibration signal. In addition, there are two vibration sensors 5, which are installed at both ends of the main beam 3 respectively.

[0026] It can be understood that when the photovoltaic tracking bracket based on sensor technology provided by the present invention is working normally, the photosensor 4 collects the current light angle data, and the control module automatically controls the motor 3 to adjust the angle of the photovoltaic panel assembly 1, so that the photovoltaic panel assembly 1 faces the direction of light, thereby improving the power generation efficiency.

[0027] Under abnormal conditions, such as strong winds, the photovoltaic rack may experience severe vibration. When the vibration data detected by the vibration sensor 4 exceeds a preset threshold, or when the stress deformation data detected by the stress sensor exceeds a preset threshold, it indicates a significant risk. At this point, the control module automatically activates a preset adjustment program to adjust the windward angle of the photovoltaic panel assembly 1 to reduce vibration.

[0028] Furthermore, during hot weather or if a PV panel assembly 1 malfunctions, the panel temperature may exceed its safe operating range. If the temperature data detected by the temperature sensor exceeds a preset threshold, this indicates a significant risk. In this case, the control module can send an alarm signal to the PV power station's control center, alerting personnel to perform maintenance. It can also adjust the PV panel assembly 1 to reduce the angle of illumination to minimize the temperature.

[0029] When the above abnormal conditions are eliminated, the system automatically returns to normal working state under the control of the control module; in addition, when adjusting the photovoltaic panel assembly 1, combining the tilt angle data collected by the tilt sensor is conducive to making the adjustment more accurate.

[0030] In summary, the photovoltaic tracking bracket based on sensor technology provided by the utility model adopts multiple types of sensors to collect multiple types of physical status data of the photovoltaic bracket, which can warn of possible abnormalities and perform appropriate control operations, effectively improving the operational safety and maintenance efficiency of the photovoltaic power station.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
