The limiting mechanism is arranged on the sliding rod 5 and can limit the sliding rod 5 to rotate circumferentially.
The power generation mechanism is arranged on the main floating body 1 and can generate power by utilizing the vertical sliding of the sliding rod 5.
The wave energy power generation buoy is placed in water, the main floating body 1 floats on the water surface 9 through the weight 12, the weight 12 limits the moving range of the main floating body 1 and prevents the main floating body 1 from being washed away by waves, the driving mechanism drives the sliding rod 5 to slide up and down along the through hole 61 by utilizing the wave energy, the power generation mechanism generates power by utilizing the up-and-down sliding of the sliding rod 5, the wave energy is converted into electric energy which is provided for equipment on the buoy, and the buoy is green and environment-friendly; in addition, because the direction of the waves is irregular, when the waves drive the sliding rod 5 to rotate through the driving mechanism, the limiting mechanism can limit the rotation of the sliding rod 5, and the power generation efficiency of the power generation mechanism is improved.
In particular, the drive mechanism comprises a base plate 4 and two floating structures.
The lower end of the slide lever 5 is hinged to the upper side of the base plate 4 by a hinge shaft 54.
Two the floating structure symmetry sets up the both sides at bottom plate 4, the floating structure includes connecting rod 41, the one end level of connecting rod 41 links firmly on the side of bottom plate 4, and the other end has set firmly flotation pontoon 42, the length direction of connecting rod 41 and articulated shaft 54's axial are mutually perpendicular, the length direction of flotation pontoon 42 and articulated shaft 54's axial are unanimous.
Because the lower end of the sliding rod 5 is hinged on the upper side surface of the bottom plate 4, when waves come from the right side and drive the buoy 42 on the right side of the bottom plate 4 to rotate upwards around the hinge shaft 54, the buoy 42 on the left side of the bottom plate rotates downwards, but the buoy 42 on the left side of the bottom plate 4 rotates downwards and is provided with upwards buoyancy by water, so that the bottom plate 4 and the sliding rod 5 move upwards, and the power generation mechanism generates power by utilizing the upwards movement of the sliding rod 5; similarly, it comes from the left side to dash when the wave, when driving the left flotation pontoon 42 of bottom plate 4 and upwards rotating round articulated shaft 54, the flotation pontoon 42 of bottom plate 4 right side rotates downwards, but the flotation pontoon 42 of bottom plate 4 right side rotates downwards and receives the ascending buoyancy of water supply, make bottom plate 4 and slide bar 5 upwards remove, power generation mechanism utilizes slide bar 5 upwards to remove and generates electricity, when two flotation pontoons 42 of bottom plate 4 both sides move to the crest simultaneously, directly drive bottom plate 4 and slide bar 5 upwards removal, when two flotation pontoons 42 of bottom plate 4 both sides move to the trough simultaneously, directly drive bottom plate 4 and slide bar 5 downwards removal, power generation mechanism can effectively utilize the wave energy to continue the electricity generation, generating efficiency is higher.
