The patent document with the publication number of CN105846643B proposes an electromagnetic energy vibration collector, which is mainly composed of a spherical shell and a square inner frame, and the collector includes main devices, such as an energy accumulator, an electromagnetic energy automatic collecting rod and a permanent magnet. The device mainly leads the permanent magnet to vibrate through the vibration of external sea waves, and the reciprocating vibration of the permanent magnet can generate induced current in the coil, thereby achieving the aim of collecting vibration energy. The invention directly utilizes the unstable vibration of sea waves to drive the permanent magnet to move, although the invention is simple and convenient, the defects of poor stability of collected energy and the like obviously exist, and the invention has larger pressure and energy loss for the subsequent collected electricity treatment stage.

A floater as a floating body is fixedly arranged at the bottom of the rack 11, and when the floater is submerged in seawater in use, the floater is subjected to the buoyancy brought by the seawater to drive the rack 11 to ascend. When the waves fluctuate, the floater is correspondingly driven to ascend or descend, and the rack 11 is correspondingly driven to move upwards or downwards.
As shown in fig. 3 and 4, the wave energy collecting device is further provided with a stroke limiting mechanism for limiting the movement stroke of the rack 11 and moving the rack 11 according to a precise movement track, and specifically, the stroke limiting mechanism comprises a first slider 21, a second slider 23 and a scissors fork 22 connected between the two sliders.

When the scissors 22 are stretched to the maximum length, the maximum stroke of the downward movement of the rack 11 corresponds to the maximum stroke, and when the scissors 22 are compressed to the minimum length, the maximum stroke of the upward movement of the rack 11 corresponds to the maximum stroke, and at the same time, the positions of the first slider 21 and the second slider 23 in the left-right direction are not adjustable, so that the rack 11 can be limited to move only in the up-down direction. In other embodiments, the first slide block 21 may be fixed to the frame 10 in a non-movable state, while the second slide block 23 is movable relative to the first slide block 21; or a guide rail extending along the up-and-down direction is arranged on the frame 10, the rack 11 is directly guided and assembled on the guide rail and moves along the guide rail, and the length of the guide rail also limits the movement stroke of the rack 11.

The rotating shaft of the two unidirectional transmission wheels is further provided with a ratchet wheel mechanism, taking the second unidirectional transmission wheel 15 as an example, as shown in fig. 5, the second unidirectional transmission wheel 15 is arranged on the rotating shaft and can rotate relative to the rotating shaft, the second unidirectional transmission wheel 15 is provided with an internal meshing tooth 153 meshed with the ratchet 152, namely, the second unidirectional transmission wheel 15 drives the ratchet 152 thereon to rotate when rotating, and the ratchet 152 drives the second unidirectional transmission wheel 15 to rotate around a specific direction.
The extending direction of the ratchet teeth at the second one-way transmission wheel 15 is different from the extending direction of the ratchet teeth at the first one-way transmission wheel 14, so that the set rotating directions of the first one-way transmission wheel 14 and the second one-way transmission wheel 15 are opposite, namely, when the rack 11 moves downwards, the first one-way transmission wheel 14 rotates, and the second one-way transmission wheel 15 idles. When the rack 11 moves upwards, the first one-way transmission wheel 14 idles, and the second one-way transmission wheel 15 rotates, namely, the rack 11 always drives one-way transmission wheel to rotate.
As shown in fig. 6, a first rotating shaft 30 is disposed between the two unidirectional transmission wheels, and a rotating axis of the first rotating shaft 30 is perpendicular to the moving direction of the rack 11 and extends in the horizontal direction. The first gear 16 is rotatably assembled on the first rotary shaft 30, and the first gear 16 is simultaneously in meshing transmission with the first one-way transmission wheel 14 and the second one-way transmission wheel 15, namely, no matter the rack 11 is lifted or lowered, the first rotary shaft 30 can rotate around a specific and unique direction through the meshing transmission of any one-way transmission wheel and the first gear 16.
