Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a portable photovoltaic power station detection device. Background Art

[0002] In the on-site detection of a photovoltaic power station, whether the daily detection results of the lines where the photovoltaic power station is located are accurate and whether the detection is fast all affect its operation efficiency to varying degrees. Usually, it includes the detection work of the current in the lines where the inverters, busbar boxes, series strings, and components are located. The existing problem is that the change in irradiance caused by weather changes will lead to inaccurate current detection data at different times. Correspondingly, in order to quickly find out the branch with abnormal power generation, it is necessary to compare the current values of the suspected abnormal branch and the normal working branch, requiring the instantaneous current values of each branch to be detected at the same time, and finding out the too low instantaneous current values. And during this process, it is necessary to exclude the phenomenon of inaccurate current values caused by the influence of the external environment.

[0003] To solve such problems, some detection devices have emerged. By setting multiple current sensors, the corresponding instantaneous current values of each branch can be obtained at the same time, thus avoiding the problem of different data test conditions caused by environmental changes. However, in actual operation, the number of current sensors is large, the structure is complex, and there are also many cables, which also bring inconvenience to detection. Summary of the Invention

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] As Figures 1 to 5 shown, the portable photovoltaic power station detection device of the present utility model mainly includes a wearable box body 1 and a handheld simulation light source 2.

[0024] The wearable box body 1 is designed in a form that can be worn by the tester, facilitating on-site operation. A power supply 11, a data collector 12, and an electrical parameter sensor are arranged inside the wearable box body 1. The power supply 11 provides power for the entire device, and the data collector 12 is responsible for collecting and processing the data of the electrical parameter sensor.

[0025] Figure 5 As

[0026] shown, the electrical parameter sensor includes a voltage sensor and a current sensor, both of which are connected to the data collector 12. During actual use, they can be connected to the wiring terminals of the photovoltaic module to collect the voltage and current data of the photovoltaic module in real time. At the same time, a partition board 13 is arranged on the top of the wearable box body 1, and the partition board 13 is used to place the voltage sensor, the current sensor, and their cables. Figure 1 and Figure 4 shown, the handheld simulation light source 2 is electrically connected to the wearable box body 1 and obtains power from the power supply 11.

[0027] In some embodiments, Figure 4As shown, multiple light sources 23 are designed and arranged in an array on the light source mounting plate 22. Such a design can provide a more uniform and powerful light intensity to better simulate sunlight. Each light source 23 is installed in a reflector cup 24, which can improve the utilization rate of the light source and make the light more concentrated.

[0028] In addition, a distance sensor 25 and a buzzer 26 are also arranged on the light source mounting plate 22. The distance sensor 25 is used to detect the distance between the light source 23 and the photovoltaic module. When the distance exceeds the set threshold, the buzzer 26 will give an alarm to remind the operator to adjust the distance between the light source and the photovoltaic module to ensure the accuracy of the detection.

[0029] It should be noted that the principle of detecting the distance and giving an alarm through the distance sensor and the buzzer, and detecting the electrical parameters by using the voltage sensor and the current sensor and transmitting the electrical parameters to the data collector belongs to the prior art and will not be elaborated here.

[0030] Figure 2 and Figure 3 As shown, a shoulder strap 14 is arranged on the side wall of the wearable box body 1 to facilitate the tester to wear. A fixing member 15 is arranged on the bottom surface of the wearable box body 1. A folding tripod 16 is arranged in the fixing member 15. This tripod can be quickly installed at the bottom of the wearable box body 1 through a quick-release joint 17 to stably support the wearable box body 1 on the ground and facilitate the operator to carry out the detection work.

[0031] The fixing member 15 specifically includes two straps 151, which are arranged at intervals on the bottom surface of the wearable box body 1, and the folding tripod 16 is arranged in the straps 151, which is convenient for installation and carrying.

[0032] Working principle:

[0033] In actual use, the wearable box body 1 is worn on the tester through the shoulder strap 14 to ensure comfortable and stable wearing. Then, the handheld simulation light source 2 is aligned with the photovoltaic module, and the distance between the light source 23 and the photovoltaic module is adjusted to ensure uniform light and appropriate intensity. At the same time, the feedback of the distance sensor 25 is monitored to ensure that the distance between the light source 23 and the photovoltaic module is within the safe range to avoid triggering the buzzer 26 alarm. The voltage sensor and the current sensor are connected to the wiring terminals of the photovoltaic module to be detected, and the real-time voltage and current data are obtained through the data collector 12 to determine whether there is a fault in the photovoltaic module.

[0034] Through the above design, the portable photovoltaic power station detection device of the present utility model not only improves the accuracy of the detection, but also its portable design makes the on-site detection work more convenient and fast.

[0035] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model fall within the scope of protection of the present utility model.
