[0010] Figure 5 A schematic overall structural view of the fourth specific implementation manner. Specific implementation manner
[0011] Specific implementation manner one: With reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 explain this implementation manner. This implementation manner is composed of an insulating housing 1, multiple composite conductive semi - disks 2, a conductive main shaft 3, and liquid metal 4; the composite conductive semi - disk 2 is composed of a metal semi - disk 2 - 1 and a dielectric 2 - 2; a layer of dielectric 2 - 2 is provided on all outer surfaces of the metal semi - disk 2 - 1; multiple composite conductive semi - disks 2 are fixedly sleeved on the conductive main shaft 3 side by side through their upper shaft holes 2 - 3, a gap 5 is provided between multiple composite conductive semi - disks 2, multiple composite conductive semi - disks 2 can rotate around the axis of the conductive main shaft 3, and the metal semi - disk 2 - 1 in each composite conductive semi - disk 2 is electrically connected to the conductive main shaft 3; the liquid metal 4 is arranged at the lower part inside the insulating housing 1, and multiple composite conductive semi - disks 2 are arranged at the upper part inside the insulating housing 1; when each composite conductive semi - disk 2 rotates to the lowest end, most of its outer surface can be immersed in the liquid metal 4; when each composite conductive semi - disk 2 rotates to the highest end, due to gravity, most of its outer surface can be separated from the liquid metal 4.
[0012] The liquid metal 4 is electrically connected to the negative electrode of the DC power supply V1, the positive electrode of the DC power supply V1 is connected to the positive electrode of the diode D1, the negative electrode of the diode D1 is electrically connected to the conductive main shaft 3, the conductive main shaft 3 is electrically connected to the positive electrode of the diode D2, the negative electrode of the diode D2 is connected to one end of the capacitor C1, and the other end of the capacitor C1 is electrically connected to the liquid metal 4. Both ends of the capacitor C1 are the output terminals of high - voltage electricity.
[0013] Working principle: When multiple composite conductive semi - disks 2 rotate to the lowermost end and most of their outer surfaces are immersed in the liquid metal 4, the capacitance value of the parallel - plate capacitor composed of the metal semi - disk 2 - 1, the dielectric 2 - 2, and the liquid metal 4 reaches the maximum value. The DC power supply V1 charges the above - mentioned parallel - plate capacitor through the diode D1. When multiple composite conductive semi - disks 2 continue to rotate, most of the outer surfaces of multiple composite conductive semi - disks 2 gradually separate from the liquid metal 4 (the liquid metal 4 flows downward due to gravity and leaves the outer surface of the composite conductive semi - disk 2), causing its capacitance value to gradually decrease. According to the parallel - plate capacitor formula C = εS / 4πkd and the capacitor energy - storage formula: E = 1 / 2CU 2 and U = Q / C, the voltage between the metal semi - disk 2 - 1 and the liquid metal 4 gradually increases (the diode D1 conducts unidirectionally to prevent back - flow to the DC power supply V1). When it is higher than the voltage across the capacitor C1, it charges the capacitor C1 at high voltage through the conductive main shaft 3 and the diode D2, and transfers electrical energy into the capacitor C1. The above - mentioned multiple composite conductive semi - disks 2 continue to rotate, and most of the outer surfaces of multiple composite conductive semi - disks 2 are gradually immersed in the liquid metal 4 again, causing its capacitance value to increase, and the voltage between the metal semi - disk 2 - 1 and the liquid metal 4 gradually decreases. When it is lower than the output voltage of the DC power supply V1 (because the diode D2 conducts unidirectionally to prevent the electrical energy of the capacitor C1 from flowing back), the DC power supply V1 charges the above - mentioned parallel - plate capacitor through the diode D1. The above - mentioned multiple composite conductive semi - disks 2 rotate continuously in a cycle, and then continuously charge the capacitor C1 at high voltage, enabling the two ends of the capacitor C1 to output electrical energy externally. The external rotating machinery can drive multiple composite conductive semi - disks 2 to rotate continuously through the conductive main shaft 3. Among them, the dielectric 2 - 2 can be barium titanate, alumina, tantalum pentoxide, or niobium pentoxide.
[0014] Specific embodiment two: In combination with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 describe this embodiment.

Other compositions and connection relationships are the same as those in the first specific embodiment. The purpose is to prevent the formation of a metal oxide film on the liquid metal 4 and increase its wettability.
[0015] Specific embodiment three: In combination with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4Describing this embodiment, the difference between this specific embodiment and the first specific embodiment is that the outer surface of each composite conductive semi - disk 2 is polished. When each composite conductive semi - disk 2 rotates to the uppermost position, most of its outer surface can smoothly and quickly separate from the liquid metal 4. Other components and connection relationships are the same as those in the first specific embodiment.
[0016] Specific embodiment four: Combining Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 Describing this embodiment, the difference between this specific embodiment and the first specific embodiment is that it is additionally provided with a DC power supply V1, a diode D1, a diode D2, and a capacitor C1; the liquid metal 4 is conductively connected to the negative electrode of the DC power supply V1, the positive electrode of the DC power supply V1 is connected to the positive electrode of the diode D1, the negative electrode of the diode D1 is conductively connected to the conductive spindle 3, the conductive spindle 3 is conductively connected to the positive electrode of the diode D2, the negative electrode of the diode D2 is connected to one end of the capacitor C1, and the other end of the capacitor C1 is conductively connected to the liquid metal 4. Both ends of the capacitor C1 are the output terminals of high - voltage electricity. Other components and connection relationships are the same as those in the first specific embodiment.

Other components and connection relationships are the same as those in the first specific embodiment.
[0018] The barium titanate in this embodiment is a dielectric with a high dielectric constant, which greatly increases the capacitance value of the flat capacitor composed of the metal semi - disk 2 - 1, the dielectric 2 - 2, and the liquid metal 4, and thus greatly increases the charging electric energy each time, that is, the electric energy for charging the capacitor C1 each time is greatly increased.
[0019] Micro - arc oxidation technology can be used to in - situ generate titanium dioxide with a dense inner layer and a porous surface layer on the titanium surface, then the hydrothermal chemical method is used to make the titanium dioxide layer react in - situ to generate a barium titanate layer, and finally the pores on the polarized surface are filled to form a barium titanate layer on the surface of the titanium.

Other components and connection relationships are the same as those in the first specific embodiment.
[0021] The alumina in this embodiment is a dielectric with a high dielectric constant, which greatly increases the capacitance value of the parallel-plate capacitor composed of the metal semi-disc 2-1, the dielectric 2-2 and the liquid metal 4. As a result, the charging electric energy per time is greatly increased, that is, the electric energy charged to the capacitor C1 each time is greatly increased. An alumina film can be formed on the surface of the aluminum alloy by anodic oxidation.
