[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1-Figure 2As shown, the present embodiment provides a multifunctional photovoltaic agricultural greenhouse, which consists of a roof and a greenhouse body 1, wherein the roof is formed by overlapping two downwardly inclined slopes 2, and tempered glass is fixedly installed on the two downwardly inclined slopes 2, so that the agricultural greenhouse is not prone to water accumulation on rainy days, and a plurality of electric slide rails 7 are arranged on the tempered glass, and the electric slide rails 7 are connected to the intelligent control module signal, and a plurality of sliders are arranged on the electric slide rails 7, and panels 8 are fixedly installed on the sliders, and the panels 8 on the electric slide rails 7 on both sides of the slope are close to the two sides of the slope 2, and the panels 8 on the electric slide rails 7 are close to the panels 8 on the adjacent electric slide rails 7 to prevent sunlight from shining into the agricultural greenhouse from the side, and a rotating device is arranged on the panel 8, and a rotating device is installed on the panel 8 A solar panel 9 is installed, and the solar panel 9 is connected to the panel 8 through a rotating device. The intelligent control module is used to control the electric slide rail 7 to slide a slider at one end of the inclined surface 2, so that the sunlight can fully irradiate into the agricultural greenhouse, so that photovoltaic power generation can be achieved while the agricultural greenhouse can also be filled with light. The intelligent control module can also control the electric slide rail 7 to slide the slider in the opposite direction, so that the panel 8 can block the sunlight and prevent the sunlight from irradiating into the agricultural greenhouse. The roof is provided with a solar sensing device, and the solar sensing device is connected to the rotating device signal. The solar sensing device is used to track the irradiation direction of the sunlight, thereby sending a signal to rotate the solar panel 9 to the irradiation direction of the sunlight through the rotating device, so that the solar panel 9 can better collect sunlight.

[0022] A photovoltaic combiner box, a photovoltaic controller, a battery, a DC distribution box, an AC control box and a photovoltaic inverter are installed in the shed body 1. An intelligent control module is arranged in the shed body 1. The photovoltaic combiner box is electrically connected to the solar cell panel 9. The photovoltaic controller is electrically connected to the photovoltaic combiner box, the battery and the DC distribution box respectively. The photovoltaic inverter is electrically connected to the DC distribution box and the AC control box respectively. The AC control box is electrically connected to the intelligent control module. The photovoltaic combiner box combines the electric energy converted by the photovoltaic power generation of the solar cell panel 9, and then controls the electric energy to be distributed to the DC distribution box through the photovoltaic controller. At the same time, the excess electric energy is distributed to the battery for storage for use when there is no sunlight. The DC distribution box distributes the DC electric energy to the photovoltaic inverter. The photovoltaic inverter converts the DC electric energy into fixed-frequency and fixed-voltage or frequency-modulated and voltage-regulated AC electric energy, and then transmits the AC electric energy to the AC control box, which distributes the AC electric energy to the intelligent control module.

[0023] The panel at the higher end of the inclined surface 2 is fixedly connected to the higher end of the inclined surface 2 through a transparent telescopic plate. When the electric slide rail 7 slides the slider toward the inclined end of the inclined surface 2, the transparent telescopic plate also extends out with the panel, and sunlight can be irradiated into the agricultural greenhouse through the transparent telescopic plate. The panel at the lower end of the inclined surface 2 is fixedly connected to the lower end of the inclined surface through a first telescopic plate. The panels are connected to each other through a second telescopic plate. The first telescopic plate and the second telescopic plate are made of opaque material. When the electric slide rail 7 slides the slider toward the higher end of the inclined surface, the first telescopic plate and the second telescopic plate also extend out with the panel. Due to the opaque material of the first telescopic plate and the second telescopic plate, sunlight is prevented from irradiating into the agricultural greenhouse through the gaps between the panels, thereby achieving the purpose of blocking sunlight. The transparent telescopic plate, the first telescopic plate and the second telescopic plate are also used to block fallen leaves or other falling objects to prevent falling objects from getting stuck in the electric slide rail 7.

If the data detected by the temperature and humidity sensor, the soil moisture sensor and the CO2 concentration sensor are higher or lower than the pre-set threshold value, the intelligent control module performs the next operation.

When the temperature and humidity return to the preset temperature and humidity thresholds, the exhaust device or the heating device stops working; when the soil moisture data detected by the soil moisture sensor is lower than the preset soil moisture threshold, the intelligent control module starts the spraying device 6 to irrigate the crops. When the soil moisture returns to the preset soil moisture threshold, the spraying device 6 stops working; when the CO2 concentration data detected by the CO2 concentration sensor is higher or lower than the preset CO2 concentration threshold, the intelligent control module starts the exhaust device to reduce the CO2 concentration or starts the CO2 generating device to increase the CO2 concentration.

When the sunlight is insufficient or the battery energy storage is insufficient, the electric energy data measured and analyzed by the electric energy metering control module is lower than the electric energy data threshold, the power switching device starts, and automatically switches to the power grid system, and the power grid system keeps supplying power to the AC control box until the electric energy data measured and analyzed by the electric energy metering control module is higher than the electric energy data threshold, the power switching device is closed, and automatically switches to the photovoltaic power generation mode.
