It can be appreciated that the photovoltaic power station can be installed in environments such as a roof of a factory building or an open mountain area, so as to ensure that the photovoltaic module can better receive converted light energy in environments with less shielding. After the photovoltaic power station operates for a long time, dust, foreign matters and the like in the environment are easily accumulated on the surface of the photovoltaic module, so that the photovoltaic module is shielded to influence the light energy receiving conversion of the photovoltaic module. Therefore, in the maintenance process of the photovoltaic power station, the cleaning device such as a cleaning water gun and a cleaning robot can be used for cleaning the photovoltaic module regularly, so that the stable and reliable operation of the photovoltaic power station is ensured. At this time, in order to realize stable water supply of the cleaning device, a pipeline for conveying water can be laid in an environment where the photovoltaic power station is installed, water is pumped from a water source by utilizing a pumping device such as a water pump at a water source 200 such as a lake or a water well near the photovoltaic power station, and cleaning operation is performed by conveying water into the cleaning device by utilizing the pipeline, so that stable operation of the photovoltaic cleaning system is ensured.

Furthermore, under the action of the liquid storage structure 30, the water supplementing device 100 can firstly extract and store water in the liquid storage structure 30 by using the first water pump 10, then store and convey the water to the cleaning device for cleaning operation by using the liquid storage structure 30, and a multi-stage water supply mode of the water supplementing device 100 can be realized, so that the first water pump 10 does not need to adopt a high-power water pump with high price to ensure the water pressure required by directly supplying water to the cleaning device by the water source 200, and under the action of the liquid storage structure 30, the cleaning device can enable water in a pipeline to flow back into the liquid storage structure 30 when the cleaning device pauses operation, thereby reducing the influence of the water pressure in a water inlet pipeline, being beneficial to better avoiding the first water pump 10 from holding pressure caused by the pause of the cleaning device, effectively reducing the failure rate of the first water pump 10, further reducing the maintenance cost of the water supplementing device 100, and ensuring that the water supplementing device 100 is more stable and reliable.
Generally, the water amount pumped by the first water pump 10 into the liquid storage structure 30 in a unit time is larger than the water amount supplied by the liquid storage structure 30 to the cleaning device, so as to ensure the stable water supply of the liquid storage structure 30 to the cleaning device, and the arrangement is generally that the operation of the first water pump 10 is stopped when the water level in the liquid storage structure 30 is about to reach the full load critical, and then the first water pump 10 is restarted to pump water when the water consumption in the liquid storage structure 30 is about to reach the minimum water level, so that the first water pump 10 is prevented from being blocked from being pressed when the first water pump 10 is continuously operated when the water storage structure is full load, and the first water pump 10 is prevented from being damaged. However, such frequent activation and deactivation of the first water pump 10 during cleaning may have some impact on the durability of the first water pump 10.
Therefore, the first valve 57 can be disposed on the water inlet pipe 50, and the first valve 57 can control the opening and closing of the water inlet pipe 50 to the water inlet end of the liquid storage structure 30 by regulating the valve, so that the first valve 57 can be opened when the photovoltaic cleaning system starts to operate or the water level in the liquid storage structure 30 is low and water is required to be replenished, so that the first water pump 10 can supply water to the liquid storage structure 30 stably, and when the photovoltaic cleaning system is not needed, the first valve 57 can be controlled to close the water inlet pipe 50 to block water from entering the liquid storage structure 30, thereby being beneficial to avoiding full load and breakage in the liquid storage structure 30 caused by false start of the first water pump 10 when the operation of the water replenishing device 100 is stopped, and improving the structural stability and reliability of the water replenishing device 100.

The second valve member 531 may be disposed on the water return branch pipe 53, when the liquid storage structure 30 normally supplements stored water, the second valve member 531 is kept in a closed state, and the communication between the water return branch pipe 53 and the water inlet pipe 50 may be blocked, so that the water extracted by the first water pump 10 may be rapidly supplied to the liquid storage structure 30 through the water inlet pipe 50, so as to ensure the water supplementing efficiency of the liquid storage structure 30, and when the first liquid level detector 33 detects that the water level in the liquid storage structure 30 exceeds a certain height and lasts for a first preset time, a signal about to be full of water may be sent to the control mechanism, so that the control mechanism alerts a user to open the second valve member 531 at this time, or the second valve member 531 is set by adopting an electric control valve member, and the second valve member 531 is electrically connected with the control mechanism, so that the control mechanism may regulate and control the second valve member 531 to open at this time, so that the water return branch pipe 53 and the water inlet pipe 50 may be connected to perform a diversion when the liquid level rises to a certain extent in the liquid storage structure 30, so as to avoid the water pressure in the water inlet pipe 50 from being excessively high and the first water pump 10 from being blocked, so that the first water pump 10 may keep the cleaning device to keep the cleaning device running at a constant power, and prevent the first water pump from stopping and stopping frequently. And when the second valve member 531 is electrically connected with the control mechanism, the first liquid level detector 33 can be utilized to feed back and regulate the opening of the valve of the second valve member 531 in real time for the water level in the liquid storage structure 30, so as to realize the control of the water quantity flowing to the liquid storage structure 30 from the water inlet pipeline 50 and the water quantity flowing to the water return branch pipe 53, thereby being beneficial to keeping the water outlet quantity and the water inlet quantity of the liquid storage structure 30 consistent in the cleaning process, ensuring the inner cavity of the liquid storage structure 30 to be at a more constant water level and guaranteeing the stable operation of the photovoltaic cleaning system.

When the water replenishing device 100 starts to operate, the first water pump 10 can keep operating at a stable operating frequency to pump water to replenish the liquid storage structure 30, and along with the rise of the water level in the inner cavity of the liquid storage structure 30, when the first liquid level detector 33 detects that the water level in the liquid storage structure 30 exceeds a certain height and lasts for a first preset time, a signal about to be full of water can be sent to the control mechanism, so that the control mechanism can control the frequency converter, the frequency converter 11 can reduce the operating frequency of the first water pump 10 at this time to reduce the water pressure of the water, the water pressure of the water outlet end of the first water pump 10 at this time is insufficient to supply water to the liquid storage structure 30, so that the first water pump 10 can be well prevented from holding the stable power to operate continuously in the cleaning process of the cleaning device, frequent start and stop of the first water pump 10 is prevented, and the stable operation of the water replenishing device 100 is ensured.
