Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a detachable flexible photovoltaic system tensile monitoring device. Background Technology

[0002] With the development of photovoltaic technology, flexible photovoltaic systems have attracted widespread attention due to their unique thinness and flexibility, especially when facing complex terrain and diverse application scenarios, where their advantages are even more obvious. Traditional flexible photovoltaic prestress (tension) monitoring devices mainly focus on force monitoring, neglecting the impact of surrounding environmental changes on system operational stability. In actual operation, severe and extreme weather conditions are one of the important factors leading to photovoltaic system accidents. However, traditional monitoring devices usually lack climate monitoring capabilities, which is a significant drawback for flexible photovoltaic power generation systems built in remote areas such as deserts and Gobi. Because these areas are far from urban centers, traditional weather forecasts may not accurately reflect the actual climate conditions on site due to geographical differences, resulting in maintenance personnel being unable to obtain accurate information in a timely manner and thus unable to prepare in advance.

[0036] Please see Figure 1 and Figure 2 This utility model discloses a detachable tensile monitoring device for a flexible photovoltaic system, comprising a tensile monitoring component 100, a meteorological instrument 200, and a controller 300. The tensile monitoring component 100 is detachably connected to the flexible component 500 of the flexible photovoltaic system and is used to monitor the tensile force of the flexible component 500. The meteorological instrument 200 is mounted on the support column 600 of the flexible photovoltaic system and is used to monitor meteorological parameters around the flexible photovoltaic system. The controller 300 is mounted on the support column 600 of the flexible photovoltaic system and is communicatively connected to the tensile monitoring component 100 and the meteorological instrument 200.

This guarantees the stability and reliability of the flexible photovoltaic power generation system and extends its service life.

[0039] Building upon traditional prestressing (tension) monitoring, this device integrates on-site environmental monitoring capabilities. It not only monitors the prestressing (tension) of the flexible component 500 but also detects real-time changes in the surrounding environment, including meteorological parameters such as wind speed, temperature, and humidity. When severe weather conditions are detected, the device can promptly issue an alarm, alerting maintenance personnel to take appropriate protective measures to prevent system failures or damage caused by weather. This comprehensive monitoring solution not only improves the safety and stability of the power generation system but also enhances its resilience, ensuring stable operation under various climatic conditions, thereby improving the overall operating efficiency and economic benefits of the photovoltaic system.

[0040] In some embodiments, see Figure 1 and Figure 2 The tensile monitoring component 100 includes a tensile sensor 110 and a tensile monitoring box 120. The tensile sensor 110 is detachably connected to the flexible component 500 of the flexible photovoltaic system, and the tensile monitoring box 120 is detachably connected to the flexible component 500 of the flexible photovoltaic system. The tensile sensor 110 and the tensile monitoring box 120 are electrically connected, and the tensile monitoring box 120 is communicatively connected to the controller 300. The tensile sensor 110 monitors changes in tensile force on the flexible component 500, and the tensile monitoring box 120 sends the monitoring data from the tensile sensor 110 to the controller 300. Both the tensile sensor 110 and the tensile monitoring box 120 can be detachably connected to the flexible component 500 of the flexible photovoltaic system, making assembly and disassembly convenient.

[0041] In some embodiments, see Figure 1 and Figure 2 The tension sensor 110 includes a sensor body 111 and a mounting member 112. The sensor body 111 has two force-receiving ends 1111 at both ends along its length. These two force-receiving ends 1111 protrude along the width of the sensor body 111 and are located on the same side of the sensor body 111. The mounting member 112 is connected to the middle of the sensor body 111 along its length. The two force-receiving ends 1111 and the mounting member 112 respectively abut against opposite sides of the flexible component 500 of the flexible photovoltaic system. The sensor body 111 is mounted on the flexible component 500 via the mounting member 112. The mounting member 112 and the force-receiving ends 1111 abut against opposite sides of the flexible component 500, ensuring stable contact between the flexible component 500 and the force-receiving ends 1111, and ensuring that the tension sensor 110 monitors the tension of the flexible component 500.

[0042] In some embodiments, see Figure 1 and Figure 2 The mounting component 112 includes a pressure plate 1121, a baffle 1122, two screws 1123, and two nuts 1124. The pressure plate 1121 has a limiting groove for the flexible component 500 of the flexible photovoltaic system to extend into. The limiting groove is located in the middle of the pressure plate 1121, ensuring that the force-bearing point of the flexible component 500 on the pressure plate 1121 is fixed and that the two force-bearing ends 1111 are subjected to balanced force. One end of each screw 1123 is connected to the pressure plate 1121. The baffle 1122 has two connecting holes, and the other ends of each screw 1123 pass through these holes. The sensor body 111 is located between the two screws 1123. The baffle 1122 abuts against the side of the sensor body 111 away from the pressure plate 1121. The nuts 1124 are threadedly connected to the screws 1123 and abut against the side of the baffle 1122 away from the pressure plate 1121. During installation, the flexible component 500 abuts against the two force-bearing ends 1111, and then a pressure plate 1121 is placed on the upper end of the flexible component 500. A baffle 1122 is placed below the sensor body 111. The lower ends of the two screws 1123 pass through the two connecting holes and are then connected to the nuts 1124 to install the sensor body 111 on the flexible component 500.

[0043] In some embodiments, see Figure 1 and Figure 2The tensile monitoring box 120 includes a base plate 121, a monitoring shell 122, and a U-shaped clamp 123. The monitoring shell 122 is mounted on the base plate 121, and the base plate 121 is connected to the flexible component 500 of the flexible photovoltaic system via the U-shaped clamp 123. A signal interface 1221 is provided on the monitoring shell 122, which is electrically connected to the tensile sensor 110 via a signal line. A monitoring antenna 1222 is provided on the monitoring shell 122, and the monitoring antenna 1222 is communicatively connected to the controller 300. The U-shaped clamp 123 is mounted on the flexible component 500 via a nut 1124, allowing for easy assembly and disassembly.

[0044] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The controller 300 includes a control housing 310, on which an antenna assembly 311 is mounted. The antenna assembly 311 includes a data receiving antenna, a data remote transmission antenna, and a GPS positioning antenna. The data receiving antenna receives tensile monitoring data from the tensile monitoring component 100 and meteorological data from the meteorological instrument 200. The data remote transmission antenna transmits data to a cloud platform, and the GPS positioning antenna locates the position of the controller 300. In cases of prestress anomalies, due to the complex on-site environment and the large number of installed flexible photovoltaic modules, it is difficult to locate the fault point accurately and promptly. A high-precision GPS positioning system has been added to the existing prestress monitoring and alarm functions. This allows maintenance personnel to quickly locate the abnormal flexible photovoltaic module based on the precise location information provided by the alarm equipment, thereby achieving efficient fault diagnosis and handling.

[0045] The control box can simultaneously receive data from several tensile monitoring components 100, achieving one-to-many communication. This allows one control box to simultaneously monitor the prestress of multiple flexible photovoltaic power generation modules 500, improving equipment utilization and reducing data monitoring costs.

[0046] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The control housing 310 is equipped with a display screen 312, which is used to display tensile data and meteorological data. Data uploaded by the tensile monitoring component 100 can be displayed on the display screen 312 in real time, making it convenient for maintenance personnel to view the data locally and grasp the status of the flexible photovoltaic power generation system.

[0047] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The control housing 310 is equipped with a waterproof cover 313, which protects the display screen 312. The waterproof cover 313 provides protection for the display screen 312, preventing foreign objects or rainwater from damaging the display screen 312.

[0048] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The control housing 310 is equipped with a switch 314 for controlling the display screen 312 to be on and off. When local data needs to be viewed, the switch 314 can be manually turned on, and the display screen 312 will light up. After maintenance is completed, the switch 314 can be turned off, and the display screen 312 will turn off, thereby reducing the power consumption of the device and increasing the device's battery life.

[0049] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The control housing 310 contains a battery and has a power interface 315 that is electrically connected to the battery. An external power supply is used to enhance device protection, preventing the internal battery from running out of power and causing the device to disconnect.
