Horizontal type wave force generating device

The invention discloses a horizontal type wave force generating device which comprises a generating device, a driving device for driving the generating device to generate electricity and a fluctuation device for controlling the driving device to move. The fluctuation device comprises a counter weight base, at least one slideway parallel to the counter weight base and wave-collecting plates which are coaxially arranged on the slideways and can perform reciprocated sliding along a direction parallel to the slideways. The driving device comprises a hydraulic motor, a hydraulic cylinder and a piston rod, wherein the hydraulic cylinder is connected with the hydraulic motor through a hydraulic pipe. One end of the piston rod is connected with the fluctuation device, and the other end of the piston rod is inserted into the hydraulic cylinder and can be driven by the fluctuation device to reciprocate along the direction parallel to the slideways. The horizontal type wave force generating device is simple and novel in structure, difficult to damage, convenient to maintain and high in energy conversion rate and generating efficiency. For a tidal power generation technology, large-area coast reclamation damming is not needed, and the horizontal type wave force generating device is flexible in achievement mode and favorable for reduction of ocean power generation cost.
