Examples

The overall design of the device is shown in figures 1-2, and the device mainly comprises a drive plate 1, a piston rod 2, a pump body 3, a conveying pipeline 4, a cantilever assembly 5, a hydraulic cylinder 6, a slewing mechanism 7 and a base member 8. The piston rod 2, the pump body 3 and the drive plate 1 are suspended at the cantilever end of the cantilever assembly 5 through a universal joint 20. Under the action of sea surface waves, the driving plate 1 drives the piston pump to do reciprocating motion, so that seawater is lifted.

The working principle of the device is that under the action of a slewing mechanism 7, the whole device rotates around a base part 8 on a deck, and a cantilever assembly 5, a piston rod 2 suspended by the cantilever assembly, a pump body 3 and a driving plate 1 can be extended out of a ship board. Meanwhile, under the action of the hydraulic cylinder 6, the inclination angle of the cantilever assembly 5 is adjusted, and finally the driving plate 1 floats in seawater at a certain draught, so that the driving plate 1 obtains the maximum wave driving force. Under the drive of waves, the whole device starts to work.

As shown in fig. 3, the driving plate 1 in this embodiment is in the shape of an equilateral hexagon; the middle part is provided with a through hole 30, and the lower end of the piston rod 2 passes through the through hole 30 and then is connected with the filter 10.

When the device is used for recycling, the arrangement process is only required to be operated reversely, the cantilever assembly 5 and related equipment are rotated to a ship deck under the action of the rotating mechanism 7, and the cantilever assembly 5 is adjusted to a storage angle through the hydraulic cylinder 6, so that the recycling is completed. In this case, the wearing parts in the piston pump assembly can be conveniently replaced and maintained.

As shown in fig. 4 to 5, the driving plate 1 of the present invention always floats on the sea surface and changes its position along with the elevation of the sea surface. When the driving plate 1 is positioned in the wave trough, the driving plate 1 drives the piston rod 2 to move downwards under the action of self weight; accordingly, when the driving plate 1 is located at the wave trough, the driving plate 1 is pushed to move upwards by buoyancy and wave flapping force, so that the driving plate 1 can periodically reciprocate under the action of the wave force.

Specifically, in a wave period, when the drive plate 1 drives the piston rod 2 to move downwards, a certain vacuum degree is formed in the pump body 3 due to the one-way conduction function of the one-way valve 9, and seawater enters the pump body 3 through the filter 10 and the internal channel of the piston rod 2; when the piston rod 2 is driven by the driving plate 1 to move upwards, the volume in the pump body 3 is reduced, and the seawater in the pump body is discharged through the pipeline. The seawater extraction and output can be realized by a complete wave period.
