The reverse gear 6 is respectively meshed with the input flywheel II8 and the output flywheel II1, so that the input flywheel II8 and the output flywheel II1 work in the same direction.

[0031] The external force cable II5 passes through the external force cable guide pulley I17 and bypasses the external force cable guide pulley II15 to be wound and connected with the input wheel 10 of the flywheel energy conversion device, and then bypasses the external force cable guide pulley III4 and the external force cable guide pulley II15 to enter the recoiler, bypasses the recoil spring extrusion pulley 16 and is fixed to the recoiler housing. The input wheel 10 is fixedly mounted on the input wheel shaft 11, and is wound and connected with the external force cable II5, and is responsible for transmitting the external energy transmitted by the external force cable II5 to the input wheel shaft 11.

[0032] The external force steel cable guide pulley Ⅰ17 , the external force steel cable guide pulley Ⅱ15 , and the external force steel cable guide pulley Ⅲ4 are all fixed on the fixing frame 18 .

[0036] A fixing ring 20 is provided in the middle position of the upper part of the box body 19, and a steel cable connecting ring 21 is provided in the middle position of the lower part of the box body 19. One end of the two external force steel cables Ⅱ5 of the two transmission systems are respectively connected to the corresponding recoil springs 14, and the other end is connected to the external force steel cable Ⅰ23 through the steel cable joint 22. The external force steel cable Ⅰ23 is connected to the steel cable connecting ring 21.

[0037] The working principle of the wave energy power generation device of the present invention is as follows:

[0038] First, set:

[0039] (1) When the external force is stretched, the input wheel 10 rotates clockwise to work; when the external force disappears, the input wheel 10 rotates counterclockwise to work. The input flywheel I9 works when it rotates clockwise; the input flywheel II8 works when it rotates counterclockwise.

[0040] (2) When the external force cable I23 is stretched by external force: the external force cable II5 is stretched out along the direction of the recoil spring extrusion pulley 16, the external force cable guide pulley II15, the external force cable guide pulley III4, the input wheel 10, and the external force cable guide pulley I17, and the recoil spring extrusion pulley 16 cooperates with the recoil spring pressure plate 13 to squeeze the recoil spring 14, and the recoil spring 14 contracts and accumulates energy; at the same time, the input wheel 10 rotates clockwise, driving the input wheel shaft 11 to rotate clockwise, the input flywheel I9 works and rotates clockwise, the output flywheel I2 works and rotates counterclockwise, and the output wheel shaft 3 rotates counterclockwise to output counterclockwise rotation energy outward.

[0041] (3) When the external force disappears: the external force cable I 23 relaxes, the return spring 14 stretches and releases energy, and the external force cable II 5 is pulled back along the direction guided by the external force cable guide pulley and returns to its original position; at the same time, the input wheel 10 is driven by the external force cable II 5 to rotate counterclockwise, the input wheel shaft 11 rotates counterclockwise, the input flywheel II 8 rotates counterclockwise, and the output flywheel II 1 rotates counterclockwise in the same direction as the input flywheel II 8 through the guidance of the reverse gear 6; the output wheel shaft 3 rotates counterclockwise and outputs counterclockwise rotation energy outward.

[0042] From the above discussion, we can see that no matter whether the input wheel inputs clockwise rotation energy or counterclockwise rotation energy, the output wheel shaft outputs counterclockwise rotation energy. In other words, the flywheel energy converter can convert energy in different directions into energy in the same direction. The flywheel energy converter is suitable for intermittent and uncertain energy absorption and utilization. It is very suitable for the absorption and utilization of tidal and wave energy.

[0043] The device of the present invention can also be used in conjunction with old equipment (buoyancy platforms, ships), and can also become a supplementary energy source for future ships; the wave energy power generation device of the present invention can be conveniently installed at the seaside, and can effectively convert wave energy into electrical energy. The entire device has low investment cost, high power generation efficiency, no noise, no pollution, no damage to the ecology, strong adaptability to sea conditions, and can be industrialized.
