The wave power unit 10 includes a crescent-shaped floating body 13 , and the upper part of the floating body 13 near the middle of the upper arc surface is provided with a hinge hole for hinged with the installation rod 12 . The interior of the floating body 13 is a closed cavity structure, which prevents the power generation unit in the inner cavity of the floating body 13 from being corroded by seawater when waves strike. In this embodiment, there is one power generating mechanism 101, which is arranged in the middle of the floating body 13. The power generating mechanism 101 includes a power generating mechanism housing 102 with a closed inner cavity, and other components of the power generating mechanism 101 are all arranged in this closed cavity.

A spherical weight 105 is fixedly connected to the lower end of the swing rod, and a transmission member 106 is hingedly connected to the upper end of the swing rod 104, and the transmission member 106 is a rod-shaped structure in this embodiment. One end of the transmission member 106 is hingedly connected to the upper end of the swing rod 104, and of course it can be movably connected to the upper end of the swing rod 104, and the other end is a piston 107 adapted to the piston cylinder 109, and the piston cylinder 109 is installed on the on the housing of the generator. The generator installation frame 108 includes two connecting rods fixedly connected with the generator housing and suspended downwards. The two connecting rods are oppositely arranged, and their cantilevered ends are respectively hinged on opposite sides of the piston cylinder 109 . The piston 107 guides and moves and is installed in the inner cavity of the piston cylinder 109 to form a piston mechanism.

The rod swings. During the swing process, the piston mechanism provides high-pressure oil to the corresponding hydraulic motor to drive it to rotate. The corresponding rotary generator works and generates electricity under the drive of the corresponding hydraulic motor, and the current is exported to the corresponding motor through the corresponding wire. in the grid.

Embodiment 2 of the wave power generation device of the present invention, as shown in Fig. 4 and Fig. 5, the wave power generation device comprises a floating base frame floating on the water surface and a base frame hinged with the floating base frame and capable of swinging along the hinge axis under the push and impact of waves. The floating body 13 is connected with a stay wire 24 on the floating base frame, and the stay wire 24 fixes the floating base frame relative to the seabed or land through the anchor 26 at the other end. The floating base frame includes a frame 21 and a supporting floating body 23 arranged on the frame 21 , the frame 21 is provided with a hinged beam 22 , and the floating body 13 is hinged on the hinged beam 22 .

The frame 21 on the floating pedestal is a rectangular frame welded by profiles. A hinged beam 22 is arranged in the middle of the rectangular frame. The hinged beam 22 is arranged side by side with the front and rear side beams of the rectangular frame at intervals. The position-limiting beam of the body 13 can prevent the safety accident of damage to the device caused by the overturning of the floating body 13 under strong wind and waves.

The supporting floating body 23 is a cylindrical hollow shell, and there are four, which are respectively fixed at the four corners of the frame 21, and the length direction of the supporting floating body 23 extends vertically so as to ensure that the frame 21 is not easy to overturn and is more stable.

The floating body 13 is a crescent-shaped hollow shell that is low in the middle and high on both sides. The middle position of the lower part is hinged in the middle of the beam through a hinge shaft. The axis of the hinge shaft is parallel to the axis of the beam to ensure that the floating body 13 swings in the front and rear , and is limited by the limit beams on the front and rear sides. The floating body 13 is sealed as a whole, so as to seal the power generating mechanism 101 inside, and protect the power generating mechanism 101 from being waterproof, dustproof and impact-proof. The structure of the generating mechanism is the same as that in Embodiment 1 of the above-mentioned wave power generating device, and will not be repeated here.

The four corners of the frame 21 are respectively connected with stay wires 24, the stay wires 24 are made of steel cables or wire ropes, and tension springs 25 are connected in series, so as to provide the necessary amount of expansion and contraction when the water level changes and when the water level changes. The frame 21 of the floating pedestal can be buffered and protected by the tension spring 25 when a large impact is caused. The backguy 24 is also provided with floats to balance the weight of the backguy 24 to ensure that the weight of the backguy 24 will not affect the floating body 13. That is, it will not be dragged on the bottom of the seabed due to the slackness of the lower part of the guy wire 24 when the tide is ebbing, causing the gravitational force applied to the floating base frame by the guy wire 24 to become smaller due to the reduced gravity, thereby causing the floating body 13 on the floating base frame to become smaller. The draft becomes shallow, so that the floating body 13 cannot work normally.

The lower end of the stay wire 24 fixes the frame 21 relative to the land (sea bottom) through the anchor, and the anchor 26 is placed so that the stay wire 24 can pull the floating base frame from four directions corresponding to the diagonal lines of the rectangular frame, so as to facilitate floating The position of the base frame is stable within a certain range on the sea surface, and the stay wires 24 will not be entangled, twisted, etc. due to the influence of the seawater eddy. The length of the stay wire 24 is at least greater than the height from the seabed to the highest tide level, so that the floating base frame will not sink into the water when the tide rises.

When the wave power generation device of this embodiment is in use: the installation of the device on the shore can be realized by means of a traction line tied to a fixed column on the shore; when the device is used in the sea away from the shore, four anchors 26 and four stay wires 24 pull the frame 21 from four directions respectively, and it is necessary to ensure that the floating pedestal is still above the water surface when the seawater is at high tide, and the wires on the floating body hinged on the crossbeam of the frame 21 and the rectifier, conversion The receiver and other components can be connected to complete the installation; when generating electricity, the waves hit the floating body back and forth, causing the floating body to swing back and forth around the hinge shaft, driving the power generating mechanism to generate electricity. The floating body is hinged on the frame 21, the floating body can swing freely and flexibly under the push of waves, and the power generation efficiency is high.

When the power generation device is located on the shore, the position of the power generation device can also be limited by tying the stay wire to the peg post on the shore. The device circles within a certain area.

The connection position between the guy wire and the power generation unit can be flexibly adjusted as needed, and the number of guy wires can also be adjusted as needed. Multiple guy wires, two guy wires can be set, and only one guy wire can be set if the guy wire strength is sufficient.

The position where the tension spring is connected in series on the backguy can be adjusted freely, and even no tension spring can be provided. At this time, the backguy should be made of elastic material.

Embodiment 3 of the wave power generation device of the present invention, as shown in Figure 6, differs from Embodiment 2 in that the tension spring is not provided on the pull wire, but is directly connected to the anchor 26, and the power generation unit passes through the door The type beam 32 is installed on the frame body, the door type beam 32 includes a hoisting part 33 at the upper end and two vertically arranged vertical bars connecting the hoisting part and the lower part, the first cross bar 34 and the second cross bar 35 pass through each The vertical bars are connected together, and the power generation unit is hingedly installed on the first horizontal bar 34.

A lifting generator 36 is installed on the hoisting part 33. When the floating body drives the two horizontal bars up and down, a vertical bar connected to the second horizontal bar drives the lifting generator to assist power generation. The lifting generator can be a linear generator or a It is a piezoelectric generator, and the piezoelectric material of the piezoelectric generator can be piezoelectric ceramics or other piezoelectric materials. The second cross bar constitutes a limit bar, which is used to prevent the floating body from producing an excessive turning angle.
