The inlet of the dosing pump 10 is connected to the drug storage tank through a pipe, and the outlet is connected to the circulating water interface 13 through a pipe.

[0028] The dosing pump 10 of this invention is a diaphragm pump or a peristaltic pump. The two dosing pumps 10 respectively deliver different types of agents and operate independently or collaboratively through the control system.

[0029] The control system described in this utility model includes a microprocessor, sensors, and an execution module. The microprocessor is installed in the control box, and the sensors are distributed at the locations that need to be monitored. The sensors are connected to the microprocessor through signal lines and transmit the detected signals to the microprocessor.

The pH sensor 14 and the conductivity sensor 15 are used to monitor water quality, and the dust sensor 17 is used to detect dust accumulation on the surface of the solar panel.

[0031] The solar panel 2 described in this invention has a power of 300W to 400W and is made of monocrystalline silicon or polycrystalline silicon.

[0032] Reference Figure 1In a preferred embodiment, the solar panel 2 of this invention is made of monocrystalline silicon with a power output of 350W, and the energy storage battery is a lithium battery pack with a capacity of 120Ah. The solar tracking mechanism is a dual-axis drive with a tracking accuracy of ±1.5°. The cleaning water tank has a capacity of 20L and is equipped with a 0.5L / min micro water pump and multiple high-pressure nozzles. The cleaning cycle can be set to once a week or triggered by a dust sensor. The dosing pump is a diaphragm pump with a flow rate range of 0.2-12L / h, and the chemical storage tank has a capacity of 60L. The control system uses an STM32 microprocessor and integrates a pH sensor, conductivity sensor, and dust sensor, with a data acquisition frequency of once every 10 minutes. The equipment casing is made of corrosion-resistant aluminum alloy, suitable for long-term outdoor use.

[0033] In practical applications, it is often necessary to address scaling, corrosion, and microbial growth simultaneously, employing a comprehensive formulation combining scale inhibitors, corrosion inhibitors, and biocides. For example, organophosphonic acid scale inhibitors, zinc salt corrosion inhibitors, and isothiazolinone biocides can be used in combination. The concentration and frequency of each agent should be adjusted appropriately based on water quality analysis results and system operation requirements. Additionally, pH adjusters can be added to maintain the pH of the circulating water between 7.5 and 9.0 to enhance the treatment effect.

[0034] The dust sensor 17 of this utility model can be an optical dust sensor, installed on the frame of the photovoltaic panel. By continuously measuring the transmission loss caused by pollutants on the glass, it calculates the amount of sunlight reduction reaching the solar module, and then converts it into a loss of power generation in real time, allowing maintenance personnel to understand when the pollutants reach the critical point.

[0038] The energy storage battery and the display are fixed in the same cabinet.

[0039] The control system of this invention operates as a closed-loop feedback regulation process. First, sensors continuously collect water quality parameters (pH value, conductivity, temperature, etc.) and solar panel status information (dust accumulation) of the circulating water, transmitting this data as electrical signals to the microprocessor via signal lines. The microprocessor quickly processes and analyzes the received data, comparing it with preset standard parameters. If the data exceeds the normal range, the microprocessor calculates the parameters that need adjustment based on its built-in control algorithm, such as the type, dosage, and timing of the added chemicals, and sends corresponding instructions to the execution module. The execution module controls the dosing pump to perform the chemical dosing operation or controls the cleaning water tank to clean the solar panels according to the instructions. Afterward, the sensors continue to monitor the system's operating status, feeding back new data to the microprocessor, forming a continuous cyclical regulation process to ensure that the entire solar-powered circulating cooling water dosing equipment is always in optimal operating condition.

[0040] The working principle of this invention is as follows: For solar power supply, a 300W to 400W monocrystalline or polycrystalline silicon solar panel is fixed to a solar tracking mechanism. A photosensor detects the light signal and transmits it to a microprocessor, which drives a motor to rotate the panel according to instructions. The tracking accuracy is ±1.5° to ±2°, efficiently generating electricity and storing it in an energy storage battery to power the device. A dust sensor detects dust accumulation on the panel and activates a cleaning water tank to spray water through nozzles for cleaning.

[0041] For chemical dosing, a chemical storage tank holds the chemicals. Sensors such as pH and conductivity monitor parameters like the circulating water quality and transmit signals to a microprocessor. The microprocessor then sends instructions to the dosing pump control unit. Two dosing pumps, either diaphragm or peristaltic, can operate independently or in tandem, drawing chemicals from the storage tank and injecting them into the circulating water interface via pipelines, thus regulating the circulating water quality. The entire process is highly automated.
