So that the first sealing plate 205 can only be opened inward to form a one-way inlet, and the second sealing plate 204 can only be opened outward to form a one-way outlet.

The second triggering structure comprises a triggering ring 202 fixed on the fixing rod 103, the triggering ring 202 is sleeved outside the roller 201, a friction surface 213 and a smooth surface are arranged on the inner wall of the triggering ring 202, the friction surface 213 is in friction fit with a friction block 212, the supporting rod 206 moves around the axis of the roller 201 in the anticlockwise direction through friction force, and the first sealing plate 205 is closed and the second sealing plate 204 of the adjacent chamber is opened.

In this embodiment, the central angle corresponding to the friction surface 213 is greater than 120 degrees and less than 240 degrees.

In this embodiment, the rotating shaft 104 is provided with a plurality of rollers 201 connected in parallel, and the plurality of rollers 201 are distributed along a spiral line.

The working procedure of this embodiment is as follows:

as shown in fig. 8 to 13, taking a single drum 201 as an example, initially, a first chamber on the right side of the drum 201 is higher than a second chamber adjacent clockwise, the first chamber is a driving chamber, a first trigger structure on the front side (clockwise direction) of the second chamber and the third chamber is located at the position of a friction surface 213 of the second trigger structure, and a first trigger structure on the front side of the first chamber is located at the position of a smooth surface of the second trigger structure. At this time, the first sealing plate 205 of the first chamber is opened and the second sealing plate 204 of the second chamber is closed; starting water inflow from the first sealing plate 205 opened at the bottom, and exhausting the extruded air from the second sealing plate 204 of the chamber; so that the right side of the drum 201 is heavier than the left side, and starts to rotate clockwise. When the sea wave rises, sea water enters from the first sealing plate 205 and cannot enter the second chamber on the left side, so that the force difference on the left side and the right side is prevented from being reduced, and the working efficiency is prevented from being reduced; when the sea wave descends, the unidirectional first sealing plate 205 is automatically closed, and even if the liquid level is lowered below the first sealing plate 205, the sea water cannot flow out.

As the drum 201 continues to rotate, when the friction blocks 212 on the support rods 206 between the first and second chambers rub against the friction surfaces 213, the generated friction force is greater than the thrust force of the return springs 209, so that the first sealing plates 205 corresponding to the first chamber are closed and the second sealing plates 204 adjacent to the second chamber are opened. I.e. the first right chamber is no longer in water and the second left chamber begins to drain (initially the second left chamber has no seawater and no need to drain); the seawater in the second chamber leaves the second sealing plate 204, and air enters from the first sealing plate 205 of the third chamber above and passes through the one-way plate 215 between the third chamber and the second chamber into the second chamber below. For the second chamber, when the sea wave rises, sea water cannot enter from the second sealing plate 204; as the ocean wave descends, the second chamber discharges seawater from the open second sealing plate 204. It should be noted that the friction force generated between the trigger structures is much smaller than the magnitude of the increase in the force difference.

As the drum 201 continues to rotate, the second chamber is gradually emptied of seawater; the first chamber gradually comes to the position of the second chamber, and the third chamber comes to the position of the first chamber to start water inflow. I.e. every 120 degrees of rotation of the drum 201, the next cycle is entered.

The plurality of rollers 201 spirally distributed on the rotating shaft 104 generate driving forces with the same direction, and all the driving forces drive the rotating shaft 104 to rotate clockwise.

In other embodiments of the green wave energy power generation system of the present invention, different from the above-described embodiments are: the rotating shaft 104 and the rotating chamber 203 are omitted, and the drum 201 is directly connected to the power generation device.

In other embodiments of the green wave energy power generation system of the present invention, different from the above-described embodiments are: four or more chambers are provided on the drum 201.

In other embodiments of the green wave energy power generation system of the present invention, different from the above-described embodiments are: the long baffle 210 and the short baffle 211 are omitted, and the structure of a ratchet or a unidirectional torsion spring is adopted to realize that the first sealing plate 205 can only be opened inwards and the second sealing plate 204 can only be opened outwards.

In other embodiments of the green wave energy power generation system of the present invention, different from the above-described embodiments are: the support bar 206 and friction structure are omitted and the sensor is used for electronically controlled triggering.

The above examples only show a few specific embodiments of the present invention, and the description thereof is more specific and detailed, and for brevity, all of the possible combinations of the features of the above examples are not described, but rather should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, it is possible to make several variations and modifications without departing from the spirit of the present invention, as long as there are no contradictions between the combinations of these technical features, which should be considered as the scope of the present description.
