The embodiment of the invention also discloses a use method of the photovoltaic power generation device adapting to the water level of the water storage and pumping reservoir, which is applied to the photovoltaic power generation device adapting to the water level of the water storage and pumping reservoir in the embodiment, as shown in fig. 12, and comprises the following steps:
step S1, arranging a recovery assembly and a corresponding first photovoltaic power generation platform 1 on a bank slope 6 of an extraction and storage reservoir;
step S2, along with the rising of the water level 7 of the water in the water pumping and storing reservoir, the first photovoltaic power generation platform 1 is separated from the recovery component, and light energy is converted into electric energy and stored;
and step S3, along with the descending of the water level 7 of the water in the water pumping and storing reservoir, the first photovoltaic power generation platform 1 descends to the recovery component, and the stored electric energy is exported to the electric energy recovery system.
For any photovoltaic power generation device with a set point, the return process of the floating ball type photovoltaic power generation platform is as follows: step 101, when the water level 7 of the pumping and accumulating reservoir falls, the area of the water area on the surface of the reservoir is reduced, then some floating ball type photovoltaic power generation platforms outside a cluster formed by a plurality of floating ball type photovoltaic power generation platforms are close to the bank slope 6 of the pumping and accumulating reservoir, step 102, when the water level 7 of the current pumping and accumulating reservoir falls to the water level 7.3 of the higher pumping and accumulating reservoir, a floating ball type water level sensing switch (buoy falling) is triggered, and the magnetic absorber 10 starts to work; as shown in fig. 1, the floating ball type photovoltaic power generation platforms close to the bank slope 6 are magnetically attracted to the bank slope 6 by the magnetic adsorbers 10 and enter the recovery range of the corresponding recovery frame 9, and the floating ball type photovoltaic power generation platforms are still in a magnetic attraction connection state with the adjacent floating ball type photovoltaic power generation platforms, as shown in fig. 10, because each floating ball type photovoltaic power generation platform is still in water, the floating force 12.2 of each floating ball type photovoltaic power generation platform can support the gravity 12.1.
Step 103, when the reservoir water level 7 of the pumping and accumulating reservoir further drops to the reservoir water level 7.4 of the lower pumping and accumulating reservoir, the buoyancy 12.2 borne by the floating ball type photovoltaic power generation platform gradually decreases to 0, as shown in fig. 1, at this time, the floating ball type photovoltaic power generation platform drops along the movement direction 11 of the second photovoltaic power generation floating platform, enters the recovery frame 9 and rests on the recovery frame 9, the floating ball type photovoltaic power generation platform connected with the magnetic attraction thereof but located outside the range of the recovery frame 9 is inclined under the influence of gravity 12.1 and generates a component 12.3 of gravity in the direction of the magnetic attraction interface, and when the component 12.3 is larger than the magnetic attraction 12.4 of the permanent magnets 3.1 of the magnetic attraction joints 3 of the two floating ball type photovoltaic power generation platforms, the floating ball type photovoltaic power generation platform is separated from the floating ball type photovoltaic power generation platform resting on the recovery frame 9 and falls back into the water, and continues to work, as shown in fig. 11.
According to the stress analysis, the configuration of the magnetic absorber 10 and the magnetic suction connector 3 related equipment should meet the following rules:
wherein:the magnetic attraction force 12.3 between the magnetic attraction joints 3 of the two floating ball type photovoltaic power generation platforms is represented; />A floating ball type photovoltaic power generation platform is subjected to magnetic force 12.5 of the magnetic absorber 10; />The self gravity 12.1 of the single floating ball type photovoltaic power generation platform is represented; />Component force 12.3 of self gravity of floating ball type photovoltaic power generation platform in the direction of magnetic attraction joint 3 is represented, and +.>The inclination angle of the magnetic attraction force between the two floating ball type photovoltaic power generation platforms in the horizontal direction (approximately 5 degrees can be obtained according to experience) is influenced by gravity.
Step 104, when the reservoir water level 7 of the pumping and storing reservoir drops to the recovery assembly arranged at the next elevation and triggers the float type water level sensing switch, the magnetic absorber 10 of the elevation recovery and release device is closed, so as to save electric power. However, as the armature of the magnetic absorber 10 is a soft magnet, the floating ball type photovoltaic power generation platform can still be weakly adsorbed on the bank slope 6 due to the attraction of the magnetic attraction joint 3, so that the electric energy is convenient to recover.
As a specific embodiment of the invention, the electricity recovery process of the floating ball type photovoltaic power generation platform is as follows: in step 201, when the floating ball type photovoltaic power generation platform is stopped at the recovery rack 9, the recovered floating ball type photovoltaic power generation platform is connected with the magnetic absorber 10 through magnetic attraction, and the first conductive contact 3.2 of the magnetic attraction connector 3 is connected with the second conductive contact 10.2 of the magnetic absorber 10 to lead out the electric energy of photovoltaic power generation stored in the storage battery in the floating ball type photovoltaic power generation platform. Step 202, if the recovery assembly includes a plurality of recovery frames 9, at this time, the electric energy transmission can be realized between each floating ball type photovoltaic power generation platform through the magnetic attraction connector 3, specifically, as shown in fig. 4, after the equipment is recovered, the floating ball type photovoltaic power generation platform connected with the magnetic absorber 10 is still connected with other two floating ball type photovoltaic power generation platforms through magnetic attraction, at this time, through the magnetic attraction connector 3, the other floating ball type photovoltaic power generation platforms can transmit electric energy to the floating ball type photovoltaic power generation platform connected with the second conductive contact 10.2, thereby realizing electric energy export.
As a specific embodiment of the invention, the release process of the floating ball type photovoltaic power generation platform is as follows: step 301, when the water level 7 of the water pumping and storing reservoir is lower than the elevation, the recovered floating ball type photovoltaic power generation platform is stopped on the recovery frame due to self gravity 12.1, and the floating ball type photovoltaic power generation platform is easy to be separated because the magnetic absorber 10 is closed at the moment, and the armature is only in weak magnetic connection with the bank slope 6 through the magnetic connector 3.
And 302, when the water level 7 of the water in the water pumping and storing reservoir rises to the position of the recovery frame 9, the parked floating ball type photovoltaic power generation platform starts to receive the buoyancy 12.2 and gradually generates a component force which is larger than the magnetic attraction 12.5 between the magnetic attraction connector 3 and the armature in the direction of the bank slope 6, so that the water is separated from the bank slope 6.
And 303, when the water level 7 of the water storage tank rises to the elevation and exceeds the elevation, the floating ball type photovoltaic power generation platform stopped at the elevation starts to float under the buoyancy 12.2 equal to the gravity 12.1 of the floating ball type photovoltaic power generation platform, and leaves the recovery frame 9 and the bank slope 6 to enter the tank for working.

Step 402, arranging recovery components along the elevation and surrounding the bank slope 6, and configuring a corresponding number of floating ball type photovoltaic power generation platforms, and step 403, when the water level 7 of the water in the water pumping and storing reservoir rises, starting the basic photovoltaic power generation floating platform and the floating ball type photovoltaic power generation platform to work. The arranged floating ball type photovoltaic power generation platform floats to the reservoir along with the rising of the reservoir water level 7 of the water pumping and storing reservoir and starts working together with the basic photovoltaic power generation floating platform, and in step 404, the floating ball type photovoltaic power generation platform is recovered along with the falling of the reservoir water level 7 of the water pumping and storing reservoir along with the height Cheng Zhujian.
