Due to the demand for light and land, photovoltaic power stations are mostly built in desert areas far away from cities, with strong winds and sand and lack of water sources. This will cause adverse factors for the daily operation and maintenance of photovoltaics, such as the cleaning of photovoltaic panels. In addition, the lack of water sources makes the damage to the environment by photovoltaic power stations more serious.

[0003] According to statistics, even simple photovoltaic cleaning can improve power generation efficiency by about 15%. Adequate water sources can ensure the irrigation of vegetation around photovoltaic sites and promote the harmonious coexistence of photovoltaics and natural ecology. Therefore, how to ensure the necessary water sources is crucial to the efficient operation of photovoltaic power stations.

As a clean energy, photovoltaic power stations can be used for other energy conversion processes in addition to electricity supply. However, existing technologies have not yet fully utilized the potential of photovoltaic power stations in water resource acquisition. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] First embodiment

[0028] See also Figure 1 to Figure 4 The present invention provides a distributed photovoltaic power station water production system, including a photovoltaic cell device 101, a power management module 102, a condensing plate water production device 103, a water collection pipeline device 104, a distributed water storage device 105, a water delivery pipeline 106 and a centralized water storage device 107.

[0029] In this embodiment, the power management module 102 transmits the electric energy provided by the photovoltaic cell device 101 to the condensing plate water making device 103, provides the condensing plate water making device 103 with the input voltage required for operation, and then starts the condensing plate water making device 103, so that the condensing plate water making device 103 condenses the water vapor in the air through the refrigeration principle to form water droplets and gathers them into water, which flows into the water collecting pipeline device 104 and is transmitted from the water collecting pipeline device 104 to the distributed water storage device 105. The water in each of the distributed water storage devices 105 is transported to the centralized water storage device 107 through the water transmission pipeline 106 for centralized storage, so that the stored water source can be used for cleaning the photovoltaic panels of the photovoltaic power station, ground irrigation, etc., to achieve the daily operation and maintenance of the photovoltaic power station and the maintenance of the environment around the photovoltaic power station, and solve the technical problem that the electric energy of the existing photovoltaic power station is not fully utilized in terms of water resource acquisition, resulting in that the excess electric energy of the photovoltaic power station cannot be fully utilized, and at the same time, it will cause adverse effects on the daily operation and maintenance of the photovoltaic power station and the environment around the photovoltaic power station.

[0030] Among them, one end of the power management module 102 is connected to the photovoltaic cell device 101, and the other end is connected to the power input end of the condensing plate water making device 103. The water collecting pipeline device 104 is located below the condensing plate water making device 103, so that the water gathered by the condensing plate water making device 103 flows into the water collecting pipeline device 104 under the action of gravity. The water collecting pipeline device 104, the distributed water storage device 105, the water pipeline 106 and the centralized water storage device 107 are connected in sequence, and the water in the water collecting pipeline device 104 is finally transported to the centralized water storage device 107 for centralized storage. The power management module 102 is used to obtain power from the photovoltaic cell device 101. The required input voltage is provided to the condensing plate water-making device 103. The power management module 102 converts the output voltage of the photovoltaic cell device 101 to the working voltage range of the condensing plate water-making device 103, and can cut off the circuit when the output voltage of the photovoltaic cell device 101 is too low, so that the condensing plate water-making device 103 is in a shutdown state. The condensing plate water-making device 103 condenses the water vapor in the air through the refrigeration principle to form water droplets, which gather into water and flow into the water gathering pipeline device 104, and finally divert to the distributed water storage device 105. The water in the distributed water storage device 105 can be transported to the centralized water storage device 107 by the water transmission pipeline 106 for centralized storage.

[0031] Secondly, the photovoltaic cell device 101 is a photovoltaic panel or a distributed energy storage battery. When the photovoltaic cell device 101 is a photovoltaic panel, the photovoltaic cell device 101 is a single panel (single photovoltaic panel) or a string panel (multiple photovoltaic panels connected in series).

[0032] Again, when the photovoltaic cell device 101 is a photovoltaic panel, the condensation plate water making device 103 is a plate-shaped device with the same size as the photovoltaic panel.

[0033] At the same time, a group of semiconductor refrigeration plates 110 are evenly arranged on the front of the condensation plate water-making equipment 103, and two adjacent semiconductor refrigeration plates 110 are connected by wires 111. The connection methods of the two adjacent semiconductor refrigeration plates 110 connected by wires 111 include series connection, parallel connection and series-parallel combination connection. The hot side of the semiconductor refrigeration plate 110 faces upward and the cold side faces downward. After power is turned on, the hot side of the semiconductor refrigeration plate 110 will dissipate heat, and the cold side will cool down to achieve a cooling effect. The water vapor in the air condenses into water droplets after encountering the cold side of the semiconductor refrigeration plate 110, and flows into the water gathering pipeline device 104 along the guide groove 112 under the action of gravity.

[0034] In addition, in order to improve the condensation effect, the cold surface of the semiconductor refrigeration plate 110 is installed with a copper sheet to increase the contact area with the air to increase the condensation speed.

[0035] In addition, the condensation plate water-making equipment 103 is suspended under the photovoltaic cell equipment 101 through a fixing device 108, the hot side of the condensation plate water-making equipment 103 faces upward and the cold side faces downward, and a certain spacing is maintained between the condensation plate water-making equipment 103 and the photovoltaic cell equipment 101, an exhaust system 109 is arranged between the condensation plate water-making equipment 103 and the photovoltaic cell equipment 101, the exhaust system 109 is used for heat dissipation and ventilation of the condensation plate water-making equipment 103 and the photovoltaic cell equipment 101, the exhaust system 109 is a fan, and by setting the exhaust system 109, the heat dissipation of the hot side of the semiconductor refrigeration plate 110 of the condensation plate water-making equipment 103 can be promoted, and the air circulation between the condensation plate water-making equipment 103 and the photovoltaic cell equipment 101 can be promoted.

[0036] Finally, the distributed water storage device 105 is a distributed local water storage tank, and the distributed water storage device 105 is installed near the condensation plate water making equipment 103.

[0037] When using a distributed photovoltaic power station water-making system of the present embodiment, the output voltage of the photovoltaic cell device 101 is converted into the working voltage range of the condensing plate water-making device 103 through the power management module 102, so that the condensing plate water-making device 103 is powered on and started. When the condensing plate water-making device 103 is started and operated, the hot surface of the semiconductor refrigeration plate 110 of the condensing plate water-making device 103 will emit heat, and the cold surface will cool down to achieve a cooling effect. At this time, the water vapor in the air will gradually condense into water droplets after encountering the cold surface of the semiconductor refrigeration plate 110, and gradually flow into the water collecting pipeline device 104 along the guide groove 112 under the action of gravity. When the water droplets flow into the water collecting pipeline After entering the device 104, the water collecting pipeline device 104 will guide the water droplets into the distributed water storage device 105, and finally transport the water in each distributed water storage device 105 to the centralized water storage device 107 through the water transmission pipeline 106 for centralized storage, so that the stored water source can be used for cleaning the photovoltaic panels of the photovoltaic power station, ground irrigation, etc., and then the daily operation and maintenance of the photovoltaic power station and the maintenance of the environment around the photovoltaic power station can be realized, which solves the technical problem that the electric energy of the existing photovoltaic power station is not fully utilized in terms of water resource acquisition, resulting in the inability to fully utilize the excess electric energy of the photovoltaic power station, and at the same time, it will have an adverse impact on the daily operation and maintenance of the photovoltaic power station and the environment around the photovoltaic power station.

[0042] S102, when the condensation plate water making device 103 is started, the condensation plate water making device 103 will condense the water vapor in the air to form water droplets and gather into water through the refrigeration principle.

[0043] Specifically, when the condensation plate water-making equipment 103 starts running, the hot surface of the semiconductor refrigeration plate 110 of the condensation plate water-making equipment 103 will dissipate heat, while the cold surface will cool down to achieve a cooling effect. At this time, the water vapor in the air will gradually condense into water droplets after encountering the cold surface of the semiconductor refrigeration plate 110.

[0044] S103, when the water vapor gathers into water, the water droplets will flow into the water collecting pipeline device 104 along the guide groove 112, and finally be guided into the distributed water storage device 105.

[0045] Specifically, when the cold surface of the semiconductor refrigeration plate 110 of the condensation plate water-making equipment 103 gradually condenses water vapor into water droplets, the condensed water droplets will gradually flow into the water gathering pipeline device 104 along the guide groove 112 under the action of gravity. After the water droplets flow into the water gathering pipeline device 104, the water gathering pipeline device 104 will guide the water droplets into the distributed water storage device 105.

[0046] S104, transporting the water in each of the distributed water storage devices 105 to the centralized water storage device 107 through the water pipeline 106 for centralized storage, thereby completing the entire water production process.
