When the air bag 5 needs to be deflated, the deflation valve 29 is opened to deflate.
The working principle of the platform adopting surge to carry out pneumatic power generation is as follows:
when the floating barrel 4 below the piston rod 3 is in the process of changing surge from a wave trough to a wave crest state (such as the 1# floating barrel and the 2# floating barrel in fig. 1), the floating barrel 4 moves upwards under the buoyancy action of the surge, so that the piston 7 is driven to move upwards in the cylinder inner cavity 6, the compression of gas in the cylinder inner cavity 6 is realized, the generated high-pressure gas is greater than the pressure of the gas in the gas bag 5, the pressure in the gas return pipe 10 is lower than the pressure in the gas bag 5, at the moment, the gas inlet valves 11 corresponding to the 1# floating barrel and the 2# floating barrel are both opened, and the gas return valves 12 are both closed, so that the high-pressure gas in the cylinder inner cavity 6 flows into the gas bag 5, the conversion of the kinetic energy of the surge to the internal energy of the compressed gas is realized, and the surge kinetic energy is stored in the gas bag 5. The high-pressure gas in the air bag 5 drives the pneumatic power generation device 8 to generate power.
When the floating barrel 4 below the piston rod 3 is in the process of changing the state of surging from a wave crest to a wave trough (such as a 3# floating barrel and a 4# floating barrel in fig. 1), the floating barrel 4 moves downwards along with the surging under the action of self gravity, the pressure in the inner cavity 6 of the cylinder barrel is reduced at the moment, the pressure is lower than the gas pressure in the gas bag 5 and the gas pressure in the gas return pipe 10, the gas inlet valve 11 is closed at the moment, the gas return valve 12 is opened, and gas discharged by the pneumatic power generation device 8 through the gas return pipe 10 enters the inner cavity 6 of the cylinder barrel.
Therefore, under the driving action of the sea surge, gas is driven to circularly flow in the cylinder inner cavity 6, the gas bag 5, the gas inlet pipe 9, the pneumatic power generation device 8 and the gas return pipe 10, and the kinetic energy of the surge is converted into electric energy by taking compressed gas as a medium in the circulating flow process, so that the circulation is repeated, the surge is utilized to generate power, and the stability of the sea platform 1 is ensured; meanwhile, because the air bag 5 and the cylinder barrel 2 store pressure air, the floating force of the offshore platform 1 is stronger.
