description of reference numerals: the device comprises a device bottom plate 1, a connecting hinge 2, a wave push plate 3, a universal joint 4, a connecting rod 5, a spring 6, a limiter 7, a generator 8 and a dam 9.

Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.

As an embodiment, the reciprocating wave energy power generation device is composed as shown in fig. 1:

the reciprocating type wave energy power generation device comprises a device bottom plate 1, a connecting hinge 2, a wave push plate 3, a universal joint 4, a connecting rod 5, a spring 6, a limiter 7 and a generator 8.

The lower end of the wave push plate 3 is fixed on the bottom plate 1 through a connecting hinge 2, and the upper end is connected with a generator 8 through a universal joint 4 and a connecting rod 5. The generator 8 is a reciprocating linear permanent magnet generator. The connecting rod 5 is driven by the wave push plate 3 to do reciprocating motion, and the connecting rod 5 is always in the same straight line with the device in the generator 8 because the universal joint 4 is arranged between the connecting rod 5 and the wave push plate 3 for connection. After the wave push plate 3 moves towards the device bottom plate 1 under the flapping of the sea waves, the spring 6 pushes the wave push plate 3, the connecting rod 5 and the like to return to the initial position, and the operation is repeated in a circulating way. Under the conditions of overlarge waves, typhoon influence and the like, the limiter 7 can prevent the wave push plate 3 from displacing to the left to cause the damage of equipment such as the generator 8 and the like.

The generator 8 is a reciprocating linear permanent magnet generator, waves impact the wave push plate 3, the wave push plate 3 drives the connecting rod 5 and a permanent magnet rotor in the generator 8 to displace leftwards, and then the permanent magnet rotor displaces rightwards under the action of the spring 6 and restores to the initial position. The device in the generator generates electricity under the reciprocating motion of left and right. When the wave slaps the wave push plate 3 again, the last power generation process is repeated, and the generator continuously generates power.

As another example:

the device is used for coast dykes and dams, because the sea tide has the tide and tide phenomenon, further installs buoyant device additional at 1 both ends of device bottom plate of this reciprocating type wave energy power generation facility, adopts movable rail to install between device bottom plate 1 and dykes and dams 9, and this reciprocating type wave energy power generation facility is along with the sea tide up-and-down motion under the buoyant device effect, can ensure that wave push pedal 3 is in the optimum height that receives the wave to clap all the time.
