The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily understand the advantages and functions of the present invention from the disclosure.

The structure, the proportions, the sizes, and the like of the present invention are only used to clarify the disclosure of the specification, and are intended to be understood and read by those skilled in the art, and are not intended to limit the implementation of the invention. Any modification of the structure, adjustment of the size, or change of the proportional relationship is considered to be within the scope of the present invention without substantial changes in the technical content.

Referring to FIG. 1 to FIG. 3, FIG. 1 is a schematic view showing the use state of the multi-wave wave power generation system of the present invention, and FIG. 2 and FIG. 3 are first preferred embodiments of the multi-wave wave power generation system. In Fig. 1, there are four sets of multi-wave direction wave power generation system 1 and a floating shed 2, and a fixed portion 3 at one end of each movable wave plate 15 of the multi-wave direction wave power generation system 1 is movably connected to a floating shed 2 floating at sea level. The pontoon 2 may be a shed used for aquaculture on the coast, or may be a buoyant hollow structure such as a plastic tube or a bamboo; if one end is fixed to the coast or harbor and the other end extends to the sea surface, The multi-wave wave power generation system can also be connected to such a support member, because the support member does not fluctuate with the waves, so the movable wave plate can have a large swing amplitude.

Each of the multi-wavelength wave power generation systems 1 in this example includes, for example, four movable wave plates 15 radially symmetrically disposed around, and the movable wave plate 15 is displaced as the ocean waves rise or fall. The state in which the multi-wave wave power generation system 1 is raised by the action of the waves is as shown in Fig. 2. The end of the movable wave plate 15 that is not connected to the fixed portion 3 is lifted up by the rising motion of the wave; when the wave is lowered, it is movable. The wave board 15 will return downward to the horizontal position as shown in FIG. The linkage rod 11 includes a linkage rod body 12 and a pivot shaft 13 connected to the movable wave plate 15, and the linkage rod body 12 in this example is exemplified as a slide type telescopic rod. When the wave undulates up and down, the linkage rod body 12 will pivot with the pivot shaft 13 as the movable wave plate 15 swings up and down. Since one end of the movable wave plate 15 is connected to the fixing portion 3, when the other end of the movable wave plate 15 is displaced upward, the length of the linkage rod body 12 is elongated by the movable wave plate 15; when the movable wave plate 15 moves downward, the linkage rod body 12 is interlocked. The length is shortened by the force of the movable wave plate 15.

When the linkage body 12 swings up and down, the pivot 13 rotates in the opposite direction or in the forward direction, and the rotational energy generated by the pivot 13 can drive the generator set 50 to generate electricity through the transmission structure of the present invention. In this example, the axial center of the linkage rod body 12 and the pivot shaft 13 are perpendicular to each other, and a large moment can be applied when the force is applied, so that the displacement of the linkage rod body 12 up and down can be efficiently converted into the reciprocating shaft of the pivot shaft 13. Rotate.

The waterproof housing 14 provided in the multi-wave wave power generation system 1 in this example can effectively prevent seawater from infiltrating into the system and cause internal parts to erode, and prevent shell seaweed from parasitic causing system damage, thereby reducing system maintenance costs. The waterproof housing 14 houses a primary planetary gear set 20, a driven bevel gear set 30, a secondary planetary gear set 40, and a generator set 50. A partial enlarged view of the primary planetary gear set 20 and the driven bevel gear set 30 is shown in FIGS. 4 and 5; a partial enlarged view of the secondary planetary gear set 40 is shown in FIG.

Each set of primary planetary gear set 20 includes a primary input shaft, a primary output shaft 26, a first stage speed increasing gear unit 21 between the primary input shaft and the primary output shaft 26, an umbrella forward actuating gear 27, and an umbrella reverse operating gear 28. In this example, the primary input shaft is the pivot 13, but those skilled in the art can also change the primary input shaft in this example to another component and connect to the pivot 13, and be driven by the reciprocating rotation of the pivot 13. . The first stage speed increasing gear unit 21 includes a first stage outer ring gear 22, a set of first stage planetary pinions 23 and a first stage sun gear 25 in this example, and the first stage planetary pinion 23 in this example is composed of three planetary pinions and three links. The first planetary carrier 24 of the planetary pinions is composed of. The four pivots 13 of the multi-wave wave power generation system 1 are respectively connected to the corresponding first-stage outer ring gears 22. Since the position of the first-stage carrier 24 is fixed, the first-stage outer ring gear 22 first drives the first-stage planetary pinions 23 to rotate. Then, the first stage sun gear 25 drives the first stage sun gear 25 to rotate. When the first stage sun gear 25 rotates, the first stage output shaft 26 connected to the first stage sun gear 25 also rotates synchronously. After the transmission of the first stage speed increasing gear unit 21, the rotation speed of the primary output shaft 26 can be increased, and the rotational speed of the pivot shaft 13 can be effectively amplified.

By the transmission of the unidirectional element (not shown), the umbrella-type forward-actuating gear 27 provided on the primary-stage output shaft 26 rotates at the same time when the primary-stage output shaft 26 rotates in the forward direction, when the primary-stage output shaft 26 rotates in the reverse direction. On the contrary, the umbrella-type reverse-actuating gear 28 provided on the primary output shaft 26 reverses at the same time when the primary output shaft 26 rotates in the reverse direction, and is not driven when the primary output shaft 26 rotates in the forward direction. In this case, the umbrella-type forward-acting gear and the umbrella-type reverse-actuating gear are opposite to each other in the opposite directions of rotation, and the two transmit the kinetic energy of the rising of the ocean wave and the falling of the ocean wave, respectively, and the forward and reverse turning energy can be effectively converted into electric energy, effectively Use the rising and falling kinetic energy of the waves.

The driven bevel gear set 30 includes an umbrella type forward driven gear 31 and an umbrella type reverse driven The gear 32 and the secondary input shaft 33, wherein the umbrella-type forward driven gear 31 and the umbrella-type reverse driven gear 32 are tooth-face-opposing, and are disposed in parallel with each other with the secondary-input shaft 33 as an axis. The umbrella-type forward driven gear 31 is driven by the umbrella-type forward-actuating gear 27, and when the umbrella-type forward-actuating gear 27 rotates in the forward direction, the umbrella-type forward driven gear 31 rotates synchronously in the opposite direction; The movable gear 32 is driven by the umbrella-type reverse-actuating gear 28, and when the umbrella-type reverse-actuating gear 28 is rotated in the reverse direction, the umbrella-type reverse driven gear 32 is synchronously reversely rotated.

Since the umbrella-type forward driven gear 31 and the umbrella-type reverse driven gear 32 are disposed in the opposite direction of the tooth surface, the tooth surface of the umbrella-type forward driven gear 31 rotates in the forward direction and the umbrella-type reverse driven gear 32 When the tooth surface is rotated in the reverse direction, the secondary input shaft 33 is rotated in the same direction. The rotation direction of the secondary input shaft 33 differs depending on the configuration of the umbrella-type forward-actuating gear 27 and the umbrella-type reverse-actuating gear 28, for example, the umbrella-type forward-actuating gear 27 and the umbrella-type reverse-actuating gear 28 in this example. When the position is reversed, the direction of rotation of the secondary input shaft 33 becomes reverse rotation, but it is still ensured that the secondary input shaft 33 has only one-way rotation regardless of whether the wave is raised or lowered.

The four movable wave plates 15 in this example may have different amplitudes and speeds of oscillation due to the action of the waves, so that the four primary output shafts 26 generate different rotation amplitudes and speeds. When the rotational speeds of the four primary output shafts 26 are different, the first-stage output shaft 26 having the fastest rotational speed is used as the main power source for driving the secondary input force shaft 33 based on the action of the above-described one-way element.

The secondary planetary gear set 40 includes a secondary input force shaft 33, a secondary output shaft 41, and a secondary speed increasing gear unit 42 interposed between the secondary input shaft 33 and the secondary output shaft 41. The secondary speed increasing gear unit 42 includes a secondary outer ring gear 43, a set of secondary planetary pinions 44 and a secondary sun gear 45, wherein the secondary planetary pinion 44 in this example is composed of three planetary pinions and links The two planet pinions consist of a second planet carrier 46.

The secondary input shaft 33 is connected to the secondary outer ring gear 43. Because the position of the secondary carrier 46 is fixed, the secondary outer ring gear 43 first drives the secondary planetary pinion 44 to rotate, and then the secondary planet is small. The gear 44 drives the secondary sun gear 45 to rotate. When the secondary sun gear 45 rotates, the secondary output shaft 41 connected to the secondary sun gear 45 also rotates synchronously. When the secondary output shaft 41 rotates, the armature in the generator set 50 is rotated, and the induced current generated by the rapid rotation of the armature in the genset 50 is outputted to generate electricity and store electricity after proper rectification. Or the purpose of power supply.

The first-stage planetary gear set in the present case is not limited to include only one primary output shaft as in the first preferred embodiment, and the umbrella-type forward-actuating gear and the umbrella-type reverse-actuating gear may be respectively disposed on different first-stage output shafts. The first-stage speed increasing gear unit of the first-stage planetary gear set can drive the two small gears through a large gear to achieve the speed increasing effect. By connecting a large gear of the first-stage input shaft, the two small gears are rotated to make the corresponding connection small. The two primary output shafts of the gear rotate. Under the structure of two primary output shafts, the umbrella-type forward driven gear and the umbrella-type reverse driven gear in the driven umbrella gear set can be the same when the tooth surface is opposite or the tooth surface is opposite. The direction is rotated. When one of the primary output shafts of the umbrella-type forward-actuated gear drives the umbrella-type forward driven gear, or the other umbrella-type reverse-actuated gear drives the umbrella-type reverse driven gear, the secondary of the driven umbrella-type gear set The input shaft will rotate in the same direction. From this, it can be seen that by the configuration of the first-stage speed increasing gear unit having the two primary output shafts and the above-described bevel gear, the output rotational speed can be increased, and both the forward and reverse rotations can be converted into single-direction rotation to generate electric power.

The structure of the linkage rod in the second preferred embodiment of the present invention is shown in FIG. 7. The linkage rod 6 is exemplified as a multi-section telescopic rod. In this example, the short side of the end of the linkage rod body 62 away from the movable wave plate 61 is a pivot 63. . When the movable wave plate 61 is lifted up with the wave, the interlocking rod body 62 is movable in the middle of the joint The portion of the linkage rod body 62 will be lifted upward with the pivot 63 as the axis; when the movable wave plate 61 falls with the wave, the movable portion of the linkage rod body 62 in the middle of the linkage rod body will be concavely folded, and the linkage rod body is interlocked. 62 will swing back with the pivot 63 as the axis.

8 is a third preferred embodiment of the multi-wave wave power generation system of the present invention. In the present embodiment, the multi-wave wave power generation system 7 further includes a hollow outer casing 71, and a waterproof casing 72 is accommodated in the middle of the hollow outer casing 71. There are four air cells 73 between the hollow outer casing 71 and the waterproof casing 72. The air bag 73 is electrically connected to the lower air reservoir 74. The air reservoir 74 is made of a flexible material or a structure having a compressible space. When the wave moves from the bottom to the top, the gas storage tank 74 is lifted up by the force of the ocean wave, and after the gas inside the gas storage tank 74 is squeezed, it is filled into the inside of the airbag 73 that is turned on, and the airbag 73 is filled with gas. The rear volume will become larger, and as a result, the area of the horizontal plane of the multi-wave wave power generation system 7 will become larger after the airbag 73 is inflated, thereby providing a larger wave force area of the system and increasing the system power generation efficiency.

The multi-wave wave power generation system can also be equipped with a separate water storage tank. When a typhoon such as a typhoon is encountered and the system cannot be removed in time, the seawater can be manually introduced into the water storage tank and the length of the linkage rod can be adjusted to maintain the system in the sea. Under the plane and reduce the wave action area, when the environmental threat is released, the seawater inside the water storage tank is discharged, and the system is raised to the initial position to generate electricity.

If the system is located far away from the coast, the multi-wave wave power generation system can be equipped with an automatic diving device to control the lifting and lowering of the system by compressing the air tank and the water tank. When the system needs to descend to sea level, after the compressed gas tank absorbs the gas in the water tank, the water tank will introduce seawater from the outside to make the system sink. If the system is to be raised back to sea level, the compressed gas The gas in the tank will be charged to the water tank, and the air inside the tank will be discharged by air to make the system rise.

The speed increasing gear unit of the present invention is not limited to the outer ring gear connecting force shaft and the sun gear connecting output shaft, the planetary frame connecting force shaft is matched with the outer ring gear connecting the output shaft, the planet carrier connecting force shaft is matched with the sun gear connecting output shaft, Can achieve the purpose of growth. By the combination of the first speed increasing gear unit and the second speed increasing gear unit, the speed of the generator set can be effectively increased, and the power generation efficiency of the system can be improved. If the power generation demand is low, the secondary speed increasing gear unit may not be set as the case may be, and the generator set is directly braked by the secondary input shaft.

In summary, the present invention provides a multi-wave wave power generation system with low construction and maintenance costs, which is suitable for various marine environments such as nearshore or offshore. In this case, through two umbrella-shaped actuating gears with opposite rotation directions and the umbrella-type driven gears with opposite tooth faces, the two opposite directions of rotation caused by the rising and falling of the waves can drive the generator set to rotate in the same direction, so as to fully utilize the waves.
