DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 3 A vibration-damping power generation float comprises a power generation shaft 1, a float housing 2, a first transmission system and a second transmission system, wherein the float housing 2 is loosely sleeved on the power generation shaft 1. The first transmission system comprises a first gear 3, a second gear 4, a first shaft 5 and a first ratchet assembly 6, wherein the first gear 3 is arranged on the power generation shaft 1, the first shaft 5 is rotationally connected to the float housing 2 and is parallel to the power generation shaft 1, the second gear 4 is arranged on the first shaft 5, the first gear 3 and the second gear 4 are transmission-matched and the two rotate in opposite directions, the first ratchet assembly 6 comprises a first pawl 600 rotationally connected to the float housing 2 and a first ratchet 601 arranged on the first shaft 5, the first pawl 600 cooperates with the first ratchet 601, and the first pawl 600 restricts the first ratchet 601 from rotating counterclockwise. The second transmission system includes a third gear 7, a fourth gear 8, a second rotating shaft 9 and a second ratchet assembly 10, the third gear 7 is arranged on the power generation rotating shaft 1, the second rotating shaft 9 is rotatably connected to the float housing 2 and is parallel to the power generation rotating shaft 1, the fourth gear 8 is arranged on the second rotating shaft 9, the third gear 7 and the fourth gear 8 are transmission-matched and the two rotate in the same direction, the second ratchet assembly 10 includes a second pawl 1000 rotatably connected to the float housing 2 and a second ratchet 1001 arranged on the second rotating shaft 9, the second pawl 1000 cooperates with the second ratchet 1001, the second pawl 1000 limits the second ratchet 1001 to rotate only clockwise, and the ratchet teeth on the first ratchet 601 and the second ratchet 1001 are in opposite directions.

[0026] When the float housing 2 rotates counterclockwise, the first transmission system drives the power generation shaft 1 to rotate clockwise. When the float housing 2 rotates clockwise, the second transmission system drives the power generation shaft 1 to rotate clockwise.

[0027] Continue reading Figure 1 In one embodiment of the present invention, the first gear 3 is directly meshed with the second gear 4, so that the first rotating shaft 5 and the generating rotating shaft 1 can rotate in opposite directions.

[0028] In another embodiment of the present invention, the first gear 3 and the second gear 4 can be transmitted through an intermediate gear, as long as the first gear 3 and the second gear 4 can rotate in opposite directions, for example, there are two intermediate gears between the first gear 3 and the second gear 4.

[0029] Continue reading Figure 1 In one embodiment of the utility model, the third gear 7 and the fourth gear 8 are matched through the transmission of the intermediate gear set, the intermediate gear set includes an intermediate shaft 11, a fifth gear 13 and a sixth gear 12, the intermediate shaft 11 is rotatably connected with the float housing 2, the fifth gear 13 and the sixth gear 12 are arranged on the intermediate shaft 11, the fifth gear 13 is directly meshed with the third gear 7, and the sixth gear 12 is directly meshed with the fourth gear 8. This design enables the second shaft 9 to have the same direction of rotation as the power generation shaft 1.

[0030] Continue reading Figure 1 The first gear 3, the second gear 4, the first rotating shaft 5, the first ratchet assembly 6, the third gear 7, the fourth gear 8, the second rotating shaft 9, the second ratchet assembly 10 and the intermediate gear set are all arranged in the float housing 2. The float housing 2 hides the transmission system inside, so that these transmission structures can be protected by the float housing 2 to avoid seawater erosion.

[0031] The float housing 2 is a fully enclosed structure locked by bolts. After removing the bolts, the float housing 2 can be opened to maintain and replace the internal structure. This is a well-known technology and will not be described in detail.

[0032] like Figure 2 As shown, the first ratchet wheel 601 can only move counterclockwise and will get stuck if it moves clockwise. Obviously, the second ratchet wheel 1001 can only move clockwise and will get stuck if it moves counterclockwise. Finally, the power generation shaft 1 can only rotate clockwise.

[0033] It should be noted that the structure of the vibration-damping power generation float other than the power generation shaft 1 constitutes a float body, and a plurality of float bodies can be installed on one power generation shaft 1 .

[0034] See also Figure 4 A floating wind turbine comprises a wind turbine foundation 14, a wind turbine body 15, the vibration reduction power generation float as described above, and a generator. The wind turbine body 15, the vibration reduction power generation float, and the generator are arranged on the wind turbine foundation 14. The power generation shaft 1 of the vibration reduction power generation float cooperates with the generator transmission to realize power generation.

[0035] Wherein, a vibration-damping power generation float is arranged on each side of the wind turbine foundation 14, and each vibration-damping power generation float has a plurality of float bodies.

[0036] The utility model uses a float as a carrier for absorbing wave energy, drives a generator through the vertical swing movement of the float, and completes the conversion of wave energy into electrical energy.

[0037] As 1 and Figure 2 As shown, the first ratchet assembly 6 (can only move counterclockwise) and the second ratchet assembly 10 (can only move clockwise) are to ensure that both can generate power during the movement of the floater floating up or down. First, in the process of the floater floating up, the entire float can be regarded as moving counterclockwise. At this time, the second ratchet assembly 10 is locked, the second shaft 9 cannot rotate relative to the float housing 2, the first ratchet 601 can rotate with the first shaft 5, the second transmission system will not transmit to the power generation shaft 1, and the first transmission system can transmit to the power generation shaft 1. On the contrary, if the floater is operated downward by the wave force, at this time, the first ratchet assembly 6 is locked, the first shaft 5 cannot rotate relative to the float housing 2, and the second ratchet 1001 moves clockwise with the second shaft 9. At this time, the first transmission system will not transmit to the power generation shaft 1, and the second transmission system can transmit to the power generation shaft 1.

[0038] During the counterclockwise movement of the float, the first ratchet 601 is driven to move with the first rotating shaft 5 by the rotation of the float. The first rotating shaft 5 is provided with a second gear 4. The movement of the float is transmitted to the third gear 3 through the transmission of the second gear 4, thereby driving the power generation rotating shaft 1 to move clockwise; during the clockwise movement of the float, the second ratchet 1001 is driven to move with the second rotating shaft 9 by the rotation of the float. The second rotating shaft 9 is provided with a fourth gear 8. The sixth gear 12 starts to rotate counterclockwise through the transmission of the fourth gear 8. At the same time, the sixth gear 12 is connected with the fifth gear 13 through the intermediate rotating shaft 11. After the fifth gear 13 is meshed and connected with the third gear 7, the power generation rotating shaft 1 is driven to move clockwise through the third gear 7. At this point, although the float has an up and down oscillating motion, through the gear change, the utility model finally makes all the floats make the power generation rotating shaft 1 move clockwise through motion conversion.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
