Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an environmental monitoring instrument for a photovoltaic power station in a cement plant. Background Technology

[0002] Currently, photovoltaic power plant environmental monitoring instruments are mainly used to measure basic meteorological parameters such as solar irradiance, temperature, and wind speed. However, for photovoltaic power plants in high-dust environments such as cement plants, existing technologies have many problems, such as: lack of dust monitoring function, inability to monitor dust concentration in real time, and difficulty in assessing the impact of dust on the power generation efficiency of photovoltaic modules; the equipment is easily contaminated, and traditional sensors are prone to clogging or damage in high-dust environments, resulting in data distortion; cleaning and maintenance rely on manual experience; and the inability to intelligently formulate cleaning plans based on environmental data leads to a decrease in power generation efficiency or excessive cleaning that increases costs.

[0003] Existing patent CN222231731U proposes a photovoltaic environmental monitoring instrument, but it does not effectively improve the special environment of cement plants, especially since it does not integrate dust monitoring and site monitoring systems. Utility Model Content

[0004] The purpose of this invention is to provide an environmental monitoring instrument for photovoltaic power stations in cement plants, which monitors dust concentration in real time and analyzes its impact on photovoltaic power generation, improves the stability and lifespan of monitoring equipment in harsh environments, and intelligently formulates photovoltaic module cleaning plans based on monitoring data. It is a dedicated environmental monitoring device for photovoltaic power stations in high dust pollution environments such as cement plants, mines, and steel plants, and can monitor meteorological data and dust concentration in real time to optimize the operating efficiency of photovoltaic modules.

[0005] To achieve the above objectives, this utility model provides an environmental monitoring instrument for a cement plant photovoltaic power station, including a counterweight base. The counterweight base is provided with a longitudinal main support and a longitudinal secondary support. The longitudinal main support is provided with a main unit, a dust concentration detector and a top mounting rod from bottom to top. The top mounting rod is provided with a wind vane, a temperature and humidity sensor and an anemometer from left to right. A battery box is provided between the longitudinal secondary support and the longitudinal main support.

[0006] Preferably, a total radiation meter, a direct radiation meter, and a diffuse radiation meter are arranged from left to right on the top of the battery box. Several batteries are installed inside the battery box. A photovoltaic panel is installed on the side of the battery box near the longitudinal sub-support, and the photovoltaic panel is electrically connected to the batteries.

[0007] Preferably, a temperature sensor is provided on the back of the photovoltaic panel, and the connection between the total radiation meter and the battery box is configured as an angle-adjustable connection structure, with the angle of the total radiation meter being the same as the angle of the photovoltaic panel.

[0008] Preferably, the input terminals of the main unit are respectively connected to the dust concentration detector, the wind vane, the temperature and humidity sensor, the anemometer, the total radiation meter, the direct radiation meter, the diffuse radiation meter, the battery box, and the temperature sensor on the back of the photovoltaic panel. The main unit is equipped with a wireless transmission module and is connected to the photovoltaic power station monitoring system of the host computer through the module.

[0009] Preferably, the surfaces of the temperature and humidity sensor, the temperature sensor, the total radiation meter, the direct radiation meter, the diffuse radiation meter, and the anemometer are all coated with a dust-repellent nano-coating.

[0010] Therefore, the environmental monitoring instrument for a cement plant photovoltaic power station with the above-described structure has the following advantages compared with the prior art:

[0011] 1. This utility model can achieve precise monitoring by linking dust concentration with meteorological data to quantify the impact of dust on power generation efficiency;

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1-3 As shown, this utility model discloses an environmental monitoring instrument for a photovoltaic power station in a cement plant. It includes a counterweight base 1, on which a longitudinal main support 2 and a longitudinal secondary support 3 are mounted. From bottom to top, the longitudinal main support 2 is equipped with a main unit 4, a dust concentration detector 5, and a top mounting rod 6. From left to right, the top mounting rod 6 is equipped with a wind vane 7, a temperature and humidity sensor 8, and an anemometer 9. A battery box 10 is located between the longitudinal secondary support 3 and the longitudinal main support 2. The dust concentration detector 5 uses the laser scattering principle to monitor the concentrations of PM2.5 and PM10 in real time. Its close integration with the photovoltaic power station system allows its data to be used to assess the impact of dust on power generation efficiency and may provide a basis for decision-making regarding the cleaning and maintenance of the power station.

[0022] A total radiation meter 11, a direct radiation meter 12, and a diffuse radiation meter 13 are arranged on the top of the battery box 10 from left to right. Several batteries 14 are installed inside the battery box 10. A photovoltaic panel 15 is installed on the side of the battery box 10 near the longitudinal sub-support 3. The photovoltaic panel 15 is electrically connected to the batteries 14.

[0023] A temperature sensor 16 is installed on the back of the photovoltaic panel 15. The connection between the total radiation meter 11 and the battery box 10 is set to an angle-adjustable connection structure. The angle of the total radiation meter 11 and the angle of the photovoltaic panel 15 are set to the same angle. Accurate irradiance data helps to more accurately evaluate the actual power generation performance of the power station and perform performance diagnosis.

[0024] The input terminals of the main unit 4 are respectively connected to the dust concentration detector 5, wind vane 7, temperature and humidity sensor 8, anemometer 9, total radiation meter 11, direct radiation meter 12, diffuse radiation meter 13, battery box 10, and temperature sensor 16 on the back of photovoltaic panel 15. The main unit 4 is equipped with a wireless transmission module, which is connected to the photovoltaic power station monitoring system of the host computer. The data is transmitted to the host computer wirelessly, which is convenient for managers to view, analyze and make decisions.

[0025] The surfaces of temperature and humidity sensor 8, temperature sensor 16, total radiation meter 11, direct radiation meter 12, diffuse radiation meter 13, and anemometer 9 are all coated with a dust-repellent nano-coating. The dust-repellent nano-coating utilizes the principles of materials science to reduce dust adhesion at the source, maintain the cleanliness of the sensor surface, ensure the accuracy of long-term monitoring data, and reduce maintenance costs and frequency.

[0026] The specific implementation process is illustrated by taking a 10MW rooftop photovoltaic power station of a cement plant as an example:

[0027] 1. Equipment installation:

[0028] The monitoring instrument is integrated within the photovoltaic power station and is securely installed using a counterweight base. It consists of a longitudinal main and auxiliary support structure. The main support, from bottom to top, houses the main unit, dust concentration detector, and top mounting rod (with wind vane, temperature and humidity sensor, and anemometer). A battery box containing a storage battery is located between the main and auxiliary supports. Photovoltaic panels are installed on the side to charge the battery. Above the battery box, a total radiation meter, a direct radiation meter, and a diffuse radiation meter are installed in sequence. Notably, the angle of the total radiation meter is adjustable and matches the angle of the photovoltaic panel. The sensor surface is coated with a dust-repellent nano-coating. The main unit integrates all sensor data and wirelessly transmits it to a host computer. The dust concentration monitor is installed 1.5 meters above the ground, avoiding direct dust sources.

[0029] 2. Data Collection:

[0030] The system is set to collect data such as irradiance, temperature, wind speed, and dust concentration every 10 minutes; when the PM10 concentration exceeds 150 μg / m³... 3 When the alarm is triggered, the event is recorded.

[0031] 3. Data Analysis:

[0032] The photovoltaic power plant monitoring system calculates the power generation efficiency loss caused by dust obstruction (e.g., "for every 100 μg / m³ increase in PM10") based on data transmitted from the main unit and using built-in algorithms. 3 (Efficiency decreases by 2%); clean suggestions and cycle plans are generated through the cloud platform (such as "Dust accumulation has reached the threshold, it is recommended to clean in 3 days").

[0033] 4. Maintenance and optimization:

[0034] The dust-repellent coating is reapplied every six months; the cleaning cycle is dynamically adjusted based on historical data to balance power generation efficiency and maintenance costs.

[0035] Therefore, this utility model provides an environmental monitoring instrument for a cement plant photovoltaic power station with the above-mentioned structure. It monitors dust concentration in real time and analyzes its impact on photovoltaic power generation, improves the stability and lifespan of the monitoring equipment in harsh environments, and intelligently formulates a photovoltaic module cleaning plan based on monitoring data. It is a dedicated environmental monitoring device for photovoltaic power stations in high dust pollution environments such as cement plants, mines, and steel plants. It can monitor meteorological data and dust concentration in real time and optimize the operating efficiency of photovoltaic modules.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
