Description

Technical Field

[0001] The invention belongs to the technical field of irradiation equipment, and in particular relates to an irradiation device capable of automatically calibrating an angle. Background Art

[0002] At present, my country's photovoltaic industry has entered the era of grid parity. With the proposal of the "carbon neutrality" goal, the installed capacity of photovoltaic power generation will enter a new rapid growth mode. At the same time, the accurate evaluation of photovoltaic system efficiency is also particularly important. Photovoltaic system efficiency refers to the ratio of the actual power generation of the system to the theoretical power generation. The evaluation of theoretical power generation involves the calculation of the cumulative solar radiation. The irradiance meter is the most commonly used test equipment in the industry to characterize the amount of radiation received by the component. It plays a vital role in the accurate and rapid measurement of photovoltaic system efficiency.

[0003] In the photovoltaic field, radiometers are generally used to measure the amount of radiation projected onto photovoltaic modules. In order to minimize the deviation between the measured value of the radiometer and the actual amount of radiation projected onto the photovoltaic modules, it is required that the installation plane of the radiometer and the plane where the photovoltaic modules are located remain parallel. At present, the installation of radiometers in photovoltaic power stations is generally achieved by adding a clamp flush with the module, and using screws to firmly fix the radiometer on the clamp through the mounting hole to ensure that the radiometer and the module maintain the same inclination angle. However, this installation method has certain disadvantages. Since the radiometer is exposed to the outdoor environment for a long time, it is likely to be affected by extreme weather such as strong winds and universities, which can easily cause the inclination angle of the radiometer to deviate from the inclination angle of the module to be measured, affecting the measurement results. At the same time, when the screw fixing method is subjected to rain corrosion, large temperature differences, etc., the equipment itself is prone to deformation, loosening, etc., which can also cause the inclination angle of the radiometer to change. Summary of the invention

[0004] The object of the present invention is to provide an irradiation device capable of automatically calibrating an angle in order to solve the above-mentioned problem.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An irradiation device capable of automatically calibrating an angle comprises a irradiometer body, wherein a controller and an inclination sensor connected to each other are arranged in the irradiometer body, and an adjustable foot assembly is arranged on the bottom side of the irradiometer body, and the adjustable foot assembly is connected to the controller.

[0007] As a further optimization scheme of the present invention, the adjustable support foot assembly includes a motor, which is connected to the controller. A groove is opened on the bottom side of the radiation meter body, and the motor is arranged in the groove. A screw rod is arranged on the output shaft of the motor. A sliding rod is slidably installed in the groove. The sliding rod is threadedly sleeved with the screw rod, and the bottom end of the sliding rod extends outside the groove and is connected to a movable support foot.

[0009] As a further optimization scheme of the present invention, a control algorithm is integrated in the controller. When the actual inclination angle received by the inclination sensor exceeds the set value ±1°, the controller drives the motor to control the movable leg to extend and retract, and calibrates the angle in real time; the calibration is stopped when the deviation value is less than ±1°.
