The following describes in detail the use steps of a pier collision avoidance device with wave energy power generation function in the present document with reference to fig. 1 to 7:

at the beginning, under the action of the compression spring 38, the first piston 36 and the buffer block 14 are positioned at the limit position on the side far from the pier 11, under the action of the auxiliary compression spring 42, the second piston 45 is positioned at the limit position on the side far from the pier 11, under the action of the spring 48, the third piston 47 and the auxiliary buffer block 18 are positioned at the limit position on the side far from the pier 11, and under the action of the auxiliary spring 56, the fourth piston 58 and the friction disc 28 are positioned at the upper limit position.

During normal operation, in the wave power generation process, because the buffering floating body 62, the buffer block 14 and the auxiliary buffer block 18 are partially positioned under the water surface, the buffering floating body 62, the buffer block 14 and the auxiliary buffer block 18 float up through buoyancy, and the up-down amplitude of the waves changes the volume occupied by the air in the transduction cavity 41 and the telescopic cavity 57, when the waves float to raise the water level in the transduction cavity 41 or the telescopic cavity 57, namely the volume of the air in the transduction cavity 41 and the telescopic cavity 57 is reduced, the air in the transduction cavity 41 and the telescopic cavity 57 is conveyed into the front-side turbine 32 through the left air flow hole 49 or the right air flow hole 49, the check valve 20, the auxiliary connecting pipe 53 and the air path hose 22, so that the front-side turbine 32 drives the front-side rotating shaft 60 to rotate, the front-side rotating shaft 60 drives the generator 61 to operate and generate power, and when the waves float to lower the water level in the transduction cavity 41 or the telescopic cavity 57, namely the transduction cavity 41, When the air volume in the telescopic cavity 57 is increased, negative pressure is generated in the energy conversion cavity 41 and the telescopic cavity 57, the negative pressure is transmitted into the turbine 32 at the rear side through the auxiliary airflow hole 50 at the right side or the airflow hole 49 at the left side, the auxiliary one-way valve 51, the connecting pipe 52, the auxiliary air path hose 21 and the air path pipe 33 at the rear side, so that the turbine 32 at the rear side sucks air, the turbine 32 at the rear side can work to drive the rotating shaft 60 at the rear side to rotate, the rotating shaft 60 at the rear side drives the generator 61 to work and generate electricity, the rotating directions of the rotating shaft 60 at the rear side and the rotating shaft 60 at the front side are the same, and the generator 61 rotates in one way to continuously generate electricity,

in the water flow power generation process, when the water area where the pier 11 is located has directional water flow, assuming that the water flow flows from right to left, the water flow drives the impeller 12 to rotate, and the water flow applies pressure to the auxiliary buffer block 18 on the right side, so that the auxiliary buffer block 18 on the right side moves a distance to the left, so that the volume of the telescopic cavity 57 is reduced, thereby generating power by the generated air flow, the impeller 12 rotates continuously along with the water flow, so that each auxiliary buffer block 18 rotates continuously, the pressure of the water flow to the auxiliary buffer block 18 on the right side is reduced after the auxiliary buffer block 18 on the right side rotates, under the action of the corresponding spring 48, the auxiliary buffer block 18 on the right side resets, the volume in the telescopic cavity 57 is increased, thereby the generator 61 generates power, the acting force of the water flow to each auxiliary buffer block 18 is continuously changed by the continuous rotation of each auxiliary buffer block 18, thereby the volume of each telescopic, in the water flow power generation process, because the impact force of the water flow is small, the water flow enables the left displacement of the right third piston 47 to be small under the action of the elastic force of the spring 48, so that the downward displacement of the fourth piston 58 and the friction disc 28 is small, the friction disc 28 cannot move downward to be abutted with the rotating disc 25,

when collision occurs, the pressure of the rammer on the auxiliary buffer block 18 is far greater than the water flow pressure, so that the corresponding auxiliary buffer block 18 moves towards one side close to the pier 11, the third piston 47 moves towards one side close to the pier 11 to a limit position firstly, at the moment, air flow generated by the movement of the third piston 47 is conveyed into the fourth piston cavity 55 through the air passage hole 40, the air conveying hose 23 and the air pipe 29, the fourth piston 58 is pushed to move downwards, the fourth piston 58 drives the friction disc 28 to move downwards through the fourth piston rod 54 to be abutted against the rotary disc 25, the pressure between the friction disc 28 and the rotary disc 25 is high, so that the friction disc 28 and the rotary disc 25 do not slide relatively, then the third piston 47 drives the second piston 45 to move towards one side close to the pier 11 through the third piston cylinder 16, the auxiliary compression spring 42 is compressed, and after the second piston 45 moves to one side close to the pier 11 to limit position, the second piston 45 drives the buffer block 14 through, The first piston rod 37 and the first piston 36 move to the limit position close to one side of the pier 11, so that the compression spring 38 is compressed, the auxiliary buffer block 18 is rotated by the elastic deformation of the auxiliary buffer block 18 and the buffer block 14 and the compression deformation of the compression spring 38, the auxiliary compression spring 42 and the spring 48, meanwhile, the auxiliary buffer block 18 is rotated by the tangential force generated by the impact of the impact object on the auxiliary buffer block 18, the auxiliary buffer block 18 drives the buffer floating body 62 to rotate by the third piston rod 17, the third piston 47, the third piston cylinder 16, the second piston 45, the second piston cylinder 15, the buffer block 14, the first piston rod 37, the first piston 36 and the first piston cylinder 13, the buffer floating body 62 rotates to drive the torsion spring 24 to be twisted and deformed to absorb part of impact energy, so that the anti-collision function is realized,

after the collision is completed, the first piston 36, the second piston 45, and the third piston 47 are moved and returned to the side away from the abutment 11 by the springs 48, the sub compression springs 42, and the compression springs 38, and the fourth piston 58 is moved and returned to the upper side by the negative pressure generated by the movement of the third piston 47.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
