Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 In this embodiment, the monitoring device for collecting cleaning data of photovoltaic power plants includes a main pole 1 and a secondary pole 2 installed on one side of the main pole 1, with a crossbar 3 installed on the top of the secondary pole 2;

[0024] An environmental monitoring mechanism is installed at the top of the crossbar 3, and a fixing rod 4 is installed at the top of the main rod 1. A thermal imager 41 is installed at the bottom of the fixing rod 4 at the end away from the auxiliary rod 2. The thermal imager 41 can identify local hot spots in the components. Uneven coverage of dust or dirt can cause abnormal temperatures.

[0025] A locking frame 5 is provided on one side of the main rod 1. The locking frame 5 has a docking groove 52 for docking with the photovoltaic panel. A tilt angle sensor 51 is connected to the top of the locking frame 5. A rotating shaft 54 ​​that rotates with the main rod 1 is connected to one side of the locking frame 5. A locking mechanism for assisting the tilt angle sensor 51 in stably adhering to the photovoltaic panel is connected to the bottom of the locking frame 51. Flat photovoltaic panels are more prone to dust accumulation than tilted photovoltaic panels. When collecting cleaning data, the cleaning frequency needs to be adjusted in conjunction with the tilt angle data.

[0026] The clamping frame 5 is connected to the solar irradiance sensor 7 on the side away from the main rod 1; the solar irradiance sensor 7 monitors the actual irradiance and compares it with the theoretical value, indirectly reflecting the power generation efficiency loss caused by surface contamination of the photovoltaic panel.

[0027] Using the above scheme, the device is installed in the photovoltaic power station, placed on one side of the photovoltaic support, to collect environmental data around the photovoltaic panels. By collecting and analyzing this data in real time, a more scientific and accurate basis for decision-making on cleaning time is provided, which facilitates the subsequent setting of cleaning frequency.

[0028] Please see Figure 1 and Figure 3 It also includes an auxiliary mounting component 6 disposed at the bottom of the main rod 1; the auxiliary mounting component 6 includes a mounting plate 61 and an adjusting rod 62 connected to one side of the mounting plate 61, a lifting rod 63 is slidably connected to the bottom of the main rod 1, the lifting rod 63 is provided with a square hole for the adjusting rod 62 to slide laterally, a first fixing bolt 64 is threadedly connected to the lifting rod 63, a plurality of first fixing holes are provided on the adjusting rod 62 to cooperate with the first fixing bolt 64, a second fixing bolt 65 is threadedly connected to one side of the bottom end of the main rod 1, a plurality of second fixing holes are provided on the lifting rod 63 to cooperate with the second fixing bolt 65, and a plurality of strip holes 66 are provided on the mounting plate 61;

[0029] Specifically, the adjustable lifting rod 63 is fixed in its vertical sliding position, the adjusting rod 62 is fixed in its horizontal sliding position, the adjusting mounting plate 61 is fixed in its appropriate position against the photovoltaic bracket, and the corresponding bolts are connected and fixed to the photovoltaic bracket through the strip hole 66.

[0030] In practical use, auxiliary installation component 6 can be used selectively, or other brackets can be set up to assist in fixing the device according to the installation position of the photovoltaic module.

[0031] Please see Figure 1 A control box 21 is installed on one side of the auxiliary rod 2; the control box 21 contains existing control components, which can receive and transmit data from various sensors.

[0032] Please see Figure 1 The environmental monitoring mechanism includes a wind speed sensor 31, a temperature and humidity sensor 32, and a wind direction sensor 33 installed on the top of the crossbar 3;

[0033] Specifically, wind speed sensor 31 and wind direction sensor 33 monitor wind direction to determine the direction of pollution sources, such as sand and dust, industrial dust, etc. Combined with the pollution situation of the geographical location, wind speed assesses the impact of natural wind on dust deposition or removal. High wind speed may accelerate dust adhesion or natural dispersal. It is necessary to combine wind direction to analyze pollution risk for subsequent assessment.

[0034] Temperature and humidity sensor 32 detects temperature and humidity. High humidity can easily cause dust to clump together or microorganisms to grow. Temperature changes may affect the ability of the photovoltaic panel surface to electrostatically attract dust.

[0035] Furthermore, the auxiliary rod 2 is provided with a sliding hole for the fixed rod 4 to slide, and the fixed rod 4 is connected to the two sides of the fixed plate, which is connected to the main rod 1 by fixing bolts;

[0036] Specifically, the position of the fixing rod 4 can be adjusted according to the position of the photovoltaic module to accurately adjust the installation position of the thermal imager 41.

[0037] Please see Figure 2 The locking mechanism includes a locking bolt 53 threaded to the bottom of the locking bracket 5, and the locking bolt 53 extends to one end of the mating groove 52 and is rotatably connected to a round washer.

[0038] Specifically, after the tilt angle sensor 51 is attached to the photovoltaic panel, the adjustable locking bolt 53 can be rotated to make the round pad contact the bottom of the photovoltaic panel, so that the tilt angle sensor 51 is stably attached and the tilt angle data is collected.

[0039] The working principle of this utility model is as follows: The device is installed in a photovoltaic power station, placed on one side of the photovoltaic support. The clamping frame 5 is connected to the photovoltaic panel. After the tilt angle sensor 51 is attached to the photovoltaic panel, the adjustable locking bolt 53 can be rotated to make the round pad contact the bottom of the photovoltaic panel, so that the tilt angle sensor 51 is stably attached and collects tilt angle data. The wind speed sensor 31 and the wind direction sensor 33 monitor the wind direction to determine the direction of the pollution source, such as sand and dust, industrial dust, etc. Combined with the pollution situation of the geographical location, the wind speed assesses the impact of natural wind on dust deposition or removal. High wind speed may accelerate dust adhesion or natural dispersal. It is necessary to analyze the pollution risk in conjunction with the wind direction to facilitate subsequent assessment. The temperature and humidity sensor 32 detects temperature and humidity. High humidity can easily cause dust to clump or breed microorganisms. Temperature changes may affect the ability of the photovoltaic panel surface to electrostatically adsorb dust. Data on the environment around the photovoltaic panel is collected. The solar irradiance sensor 7 monitors the actual irradiance. The thermal imager 41 identifies local hot spots of the component. By collecting and analyzing these data in real time, a more scientific and accurate decision basis is provided for the cleaning time, which facilitates the subsequent setting of the cleaning frequency.

[0040] By monitoring environmental data and photovoltaic module power generation efficiency in real time, the system can intelligently determine the timing of cleaning and issue early warning signals so that maintenance personnel can take timely measures to clean the system.
