Preferably, a fourth communication hole is further formed inward in the outer wall of each air collecting shell 4, and the fourth communication hole is communicated with the flow channel; the offshore oscillating water column power generation ship further comprises two second sealing covers 8, the second sealing covers 8 correspond to the fourth communication holes one to one, and the second sealing covers 8 are opposite to the fourth communication holes and are detachably connected to the wind collecting shell 4 through screws.
Through setting up fourth intercommunicating pore, the sealed lid 8 of second, because the change of atmospheric pressure that the change of the four seasons difference in temperature drove, open the sealed lid 8 of second when the atmospheric pressure in the gas collection chamber is too big or undersize, make the gas collection chamber is linked together through runner, fourth intercommunicating pore, bleeder vent and external world, the equilibrium atmospheric pressure in the gas collection chamber.
The specific working process of the invention is as follows: when the invention is arranged at sea, the ship body 11 can swing back and forth along with the fluctuation of sea waves when floating on the sea level, in the fluctuation process of the ship body 11, the liquid in the containing cavity moves along with the fluctuation of the sea waves, when water flowing in the containing cavity is gathered at one side, the flexible bag 2 at the position can be pressed to be expanded or contracted outwards, the flexible bag 2 at the other side is correspondingly changed, the deformed flexible bag 2 can enable the gas in the wind collecting shell 4 to form positive pressure and negative pressure respectively, so that airflow is pushed to flow in the shell 1, when the head of the ship body 11 inclines downwards, the liquid can be gathered towards the head close to the ship body 11, the flexible bag 2 close to the head of the ship body 11 can be pushed to be protruded outwards, so that the air in the wind collecting cavity is in a positive pressure state, the flexible bag 2 close to the tail of the ship body 11 is sunken inwards, so that the air in the wind collecting cavity is in a negative pressure state, and the huge pressure difference enables the air at, the flowing air can push the blades 32 to rotate, the blades 32 drive the rotating shaft 33 to rotate, the rotating shaft 33 drives the rotors of the two generators 31 to rotate, the generators 31 generate electricity, and the wave energy is converted into electric energy; when the head of the hull 11 is tilted upwards, liquid is gathered towards the tail part close to the hull 11, and the flexible bag 2 close to the tail part of the hull 11 is pushed to protrude outwards, so that the air in the air collecting cavity is in a positive pressure state, the flexible bag 2 close to the head part of the hull 11 is sunken inwards, the air in the air collecting cavity is in a negative pressure state, and the air at the tail part of the shell 1 flows towards the head part of the shell 1 due to huge pressure difference to form airflow.
Because the existence of wind collection shell 4, and wind collection shell 4, flexible bag 2, lid 15, hull 11 surround and are formed with a wind collection chamber, and the in-process of flexible bag 2 deformation can form positive negative pressure gas district in the wind collection chamber, can oppress the gas in the wind collection chamber for gas flows to the negative pressure district, and gas follows in the wind collection chamber the direction of runner removes, because the runner is constantly reduced to the direction internal diameter that is close to blade 32, can blow the gas flow that flows on blade 32 with concentrated mode, can promote blade 32 and rotate fast, improve the generated energy.
By arranging the cover body 5a, the airflow can be prevented from diverging outwards when flowing through the power generation assembly 3, the airflow flowing area can be limited, by arranging the air duct assembly 5, in the process that the airflow flows from one end of the cover body 5a to the other end, due to the limiting action of the first limiting block 5c, the first baffle 5b cannot rotate, the airflow pushes the second baffle 5d to rotate, the airflow flows from the upper layer of the cover body 5a to the other end of the cover body 5a, due to the limiting action of the third limiting block 5g, the third baffle 5f cannot rotate, the airflow pushes the fourth baffle 5h to rotate, and the airflow flows along the upper side of the cover body 5a, so that the blades 32 rotate clockwise; when the air current flows to the in-process of one end by the other end of the cover body 5a, because the limiting action of fourth stopper 5i, make fourth baffle 5h unable to rotate, the air current promotes third baffle 5f to rotate, the air current flows along the downside of the cover body 5a, gas flows to the one end of the cover body 5a from the lower floor of the cover body 5a, because the limiting action of second stopper 5e, make second baffle 5d unable to rotate, the air current promotes first baffle 5b to rotate, the air current flows along the downside of the cover body 5a, the air current promotes blade 32 clockwise rotation, so no matter how the hull 11 inclines, the air current can only promote blade 32 clockwise rotation, make the whole effectual work of wind energy.
The communicating pipe 74, the fifth baffle 711, the two fifth stoppers 712, the sixth baffle 721, the two sixth stoppers 722, the seventh baffle 731, and the two seventh stoppers 732 are provided.
When the air pressure in the air collecting cavity is overlarge, the gas pushes the seventh baffle 731 to rotate, the gas enters the air cavity through the third communicating hole, when the pressure in the air cavity is overlarge than a certain value, the gas pushes the sixth baffle 721 to rotate, the gas is discharged out of the cover body 5a through the second communicating hole, when the air pressure in the air collecting cavity is suddenly and rapidly increased, part of the gas in the air collecting cavity is discharged, and the damage of certain parts caused by the overlarge air pressure in the cover body 5a is prevented,
when the air pressure in the flow passage is reduced, a certain pressure difference exists between two ends of the fifth baffle 711, when the pressure difference is greater than a certain value, the air in the air cavity pushes the fifth baffle 711 to rotate, the air flow directly enters the cover body 5a through the communicating pipe 74, the air flow enters the upper layer of the cover body 5a through the communicating pipe 74, and the air flow of the communicating pipe 74 close to the other end of the cover body 5a enters the lower layer of the cover body 5a so that the vane 32 always rotates clockwise.
Through setting up air cavity and wind pressure adjusting part 7 for the pressure of the gas that gets into cover body 5a is relatively stable, has reduced the abrupt change of pressure, makes blade 32 smooth rotation relatively, avoids blade 32 to rotate too fast suddenly or too slowly, makes the rotation of blade 32 more steady.
The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
