Description

Technical Field

[0001] The present invention relates to the technical field of ocean wave power generation, and in particular to an ocean wave floating-based power generation device and method. Background Art

[0002] With the limitation of conventional energy and the increasingly prominent environmental problems, new energy with environmental protection and renewable characteristics has been paid more and more attention. With the development of low-power wireless sensors, the use of clean and renewable energy such as solar energy, wind energy and wave energy to generate micro power supplies to provide power for sensor nodes has been widely concerned by all walks of life. Ocean energy refers to various renewable energy sources contained in seawater, including tidal energy, wave energy, ocean current energy, seawater temperature difference energy, seawater salinity difference energy, etc. These energies have the advantages of being renewable and not polluting the environment. They are a new energy with strategic significance that needs to be developed and utilized urgently.

[0003] Wave energy is an important component of ocean energy. The current wave power generation device uses the fluctuations formed by waves to realize the transmission of wave energy from reciprocating motion to unidirectional rotational motion through a transmission mechanism, driving the generator to generate electricity. It adopts a mechanical device of rack, gear and ratchet mechanism. As the waves rise and fall, the rack and the float rise and fall together, driving the two gears meshing with it to rotate reciprocatingly. The gears are each connected to the shaft with a ratchet mechanism. When the rack rises, the left gear drives its shaft to rotate counterclockwise, and the right gear idles clockwise. Through the transmission of the next gear, the generator is driven to rotate clockwise to generate electricity.

[0004] Since there are many elements in seawater, and the main working parts of the wave power generation device are relatively precise transmission mechanical parts such as gears and ratchet mechanisms, and wave power generation uses buoys to drive the rotation of the shaft to achieve power generation of the generator, the transmission parts and shafts are in the marine environment and inevitably come into contact with the waves. They are easily corroded or damaged by seawater erosion, which affects the transmission of the gears and the rotation of the shaft. It is necessary to overcome the resistance caused by rust, thereby reducing the power generation efficiency. Summary of the invention

[0033] The present invention also provides a method for generating electricity based on sea wave floating, using the above-mentioned power generation device based on sea wave floating, comprising the following steps:

[0034] S1, buoy 1 and buoy 2 provide buoyancy to keep the platform above the sea surface. Driven by the waves, buoy 1 and buoy 2 will swing up and down on the sea surface with the rotating shaft as the center. During the swinging process, buoy 1 and buoy 2 will drive large gear 1 and large gear 2 to rotate slightly left and right;

[0035] S2, when the large gear 1 and the large gear 2 rotate clockwise, the driven gear ring of the one-way rotating flywheel 1 rotates counterclockwise, and the driven gear ring rotates in the direction of the pawl, the center wheel is in a stopped state, and the driven gear ring of the one-way rotating flywheel 2 rotates clockwise, pushing the pawl and the center wheel to rotate clockwise;

[0036] S3, when the large gear 1 and the large gear 2 rotate counterclockwise, the driven gear ring of the one-way rotating flywheel 1 rotates clockwise, pushing the pawl and the center wheel to rotate clockwise, and the driven gear ring of the one-way rotating flywheel 2 rotates counterclockwise, and the center wheel is in a stopped state;

[0038] S5. The driving shaft drives the reciprocating screw to rotate, driving the conveying plate to move back and forth inside the conveying bin. During the movement of the conveying plate, the pressure inside the conveying bin changes, and the lubricating oil at the bottom of the protective cover is sucked into the interior of the conveying bin and transported to the top of the protective cover through the oil outlet pipe and sprayed on the surface of the one-way transmission component to lubricate it.

[0039] The working principle and beneficial effects of the present invention are:

[0040] 1. In the present invention, the pawl is pressed against the tooth groove of the driven gear ring by a compression spring. When the driven gear ring rotates counterclockwise, the center wheel does not rotate. When the driven gear ring rotates clockwise, the pawl and the center wheel are pushed to rotate clockwise, thereby realizing the unidirectional rotation of the one-way rotating flywheel 1 and the one-way rotating flywheel 2. Driven by the waves, the float 1 and the float 2 swing up and down, driving the rotating shaft, the large gear 1 and the large gear 2 to rotate. The one-way rotating flywheel 1 and the large gear 1 have opposite directions, while the one-way rotating flywheel 2 and the large gear 2 have the same direction. No matter which direction the rotating shaft rotates, the center wheel is driven to rotate unidirectionally, that is, the input end of the generator is driven to rotate unidirectionally to generate electricity.

[0041] 2. In the present invention, the protective cover is used to protect the large gear 1, large gear 2, one-way rotating flywheel 1 and one-way rotating flywheel 2 and other components to prevent them from being eroded by sea water. The rotating shaft is rotated under the driving action of the waves, and the driving shaft is rotated under the action of the one-way transmission assembly. The driving shaft rotates while driving the reciprocating screw to rotate, thereby driving the conveying plate to reciprocate inside the conveying bin. During the movement of the conveying plate, the pressure in the conveying bin changes, and the lubricating oil at the bottom of the protective cover is sucked into the conveying bin and sprayed on the surface of the one-way transmission assembly through the oil outlet pipe, so as to lubricate the large gear 1, large gear 2, one-way rotating flywheel 1 and one-way rotating flywheel 2 and other components, thereby reducing the loss of wave energy.

[0042] 3. Therefore, compared with the wave power generation device in the prior art, the present invention protects the precision transmission components such as the one-way transmission assembly through the protective cover, and at the same time, the one-way rotation of the driving shaft generated by the buoyancy of the waves drives the reciprocating screw to rotate, driving the conveying plate to move back and forth inside the conveying bin, so that the lubricating oil in the protective cover circulates and rises to spray on the surface of the one-way transmission assembly and other precision components to lubricate them, thereby reducing the energy loss in the process of converting wave energy into electrical energy.

[0062] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Embodiment 1, as Figures 1 to 10 As shown, this embodiment proposes a power generation device based on wave floating, including a generator 1, a platform 2, a buoy group, a one-way transmission component and a protective component. Compared with the wave power generation device in the prior art, the present invention protects the one-way transmission component and other precision transmission components through a protective cover 501, and at the same time, the one-way rotation of the drive shaft 203 generated by the buoyancy of the waves drives the reciprocating screw 603 to rotate, driving the conveying plate 602 to reciprocate inside the conveying bin 601, so that the lubricating oil in the protective cover 501 circulates and rises to spray on the surface of the one-way transmission component and other precision components to lubricate them, thereby reducing the energy loss in the process of converting wave energy into electrical energy.

[0064] like Figures 1 to 3As shown, the generator 1 is arranged on the platform 2, and a plurality of buoy groups are arranged. The platform 2 is provided with a plurality of through installation openings, and the buoy group is arranged inside the installation opening. The buoy group includes a buoy 101, a buoy 102 and a rotating shaft 103. A connecting plate 104 is arranged between the buoy 101 and the buoy 102, and the rotating shaft 103 is arranged on the connecting plate 104. The rotating shaft 103 is rotatably arranged on the platform 2. The buoy 101 and the buoy 102 float on the sea surface to support the platform 2. There is a certain distance between the buoy 101 and the buoy 102, and they are hard connected under the action of the connecting plate 104. Under the action of the waves, the buoy 101 and the buoy 102 are not raised and lowered synchronously, and the two swing up and down with the rotating shaft 103 as the center, thereby driving the rotating shaft 103 to rotate.

[0065] like Figures 1 to 7 As shown, the one-way transmission component is used to convert the lifting of the floating group into a one-way rotation of the input end of the generator 1. The one-way transmission component includes a large gear 1 201, a large gear 202, a one-way rotating flywheel 1, a one-way rotating flywheel 2 and a drive shaft 203. The large gear 1 201 and the large gear 2 202 are coaxially rotatably arranged on the platform 2. Specifically, the large gear 1 201 and the large gear 2 202 are coaxially arranged on the rotating shaft 103, the one-way rotating flywheel 1 and the one-way rotating flywheel 2 are both rotatably arranged on the platform 2, the one-way rotating flywheel 1 is meshed with the large gear 1 201, the one-way rotating flywheel 2 is connected to the large gear 2 202 through a transmission member, the one-way rotating flywheel 2 and the large gear 2 202 rotate in the same direction, and the drive shaft 203 is rotatably arranged on the platform 2. The end of the driving shaft 203 is connected to the input end of the generator 1. The driving shaft 203 and the one-way rotating flywheel one and the one-way rotating flywheel two are coaxially arranged. The rotating shaft 103 is driven to rotate by the up and down swinging of the float one 101 and the float two 102, thereby driving the large gear one 201 and the large gear two 202 to rotate synchronously. The large gear one 201 and the one-way rotating flywheel one have opposite rotation directions, and the large gear two 202 and the one-way rotating flywheel two have the same rotation direction. No matter how the float one 101 and the float two 102 swing up and down, that is, no matter whether the rotating shaft 103, the large gear one 201 and the large gear two 202 rotate clockwise or counterclockwise, there will always be one-way rotating flywheel one or one-way rotating flywheel two that rotates in the same direction as the input shaft of the generator 1 when generating electricity.

[0066] like Figure 8As shown, in order to realize the unidirectional rotation of the one-way rotating flywheel 1 and the one-way rotating flywheel 2, the one-way rotating flywheel 1 and the one-way rotating flywheel 2 have the same structure. The one-way rotating flywheel 1 includes a center wheel 301, a driven gear ring 302 and a ratchet 303. The center wheel 301 is coaxially arranged on the driving shaft 203, and the driven gear ring 302 is rotatably arranged on the platform 2. The driven gear ring 302 is located outside the center wheel 301 and is coaxially arranged with the center wheel 301. The driven gear ring 302 is meshed with the large gear 1 201. A support frame 3 is arranged on the platform 2. The driven gear ring 302 is rotatably arranged on the support frame 3 through a rotating ring. The ratchet 303 is rotatably arranged The driven gear ring 302 is provided with a plurality of tooth grooves matching the ratchet 303. Under the action of the compression spring, the ratchet 303 is pressed against the tooth groove of the driven gear ring 302. When the driven gear ring 302 rotates counterclockwise, the raised position of the tooth groove moves along the outer side of the ratchet 303, pressing the ratchet 303 inward, squeezing the compression spring to shorten it, so that the center wheel 301 can be in a stationary state when the driven gear ring 302 rotates, and when the driven gear ring 302 rotates clockwise, the center wheel 301 can be in a stationary state. During rotation, the tooth groove blocks the pawl 303, thereby pushing the pawl 303 and the center wheel 301 to rotate. When the large gear 1 201 and the large gear 2 202 rotate clockwise, the driven gear ring 302 in the one-way rotating flywheel 1 rotates counterclockwise, and the center wheel 301 does not rotate. The driven gear ring 302 in the one-way rotating flywheel 2 rotates clockwise, pushing the pawl 303 and the center wheel 301 to rotate clockwise, thereby driving the driving shaft 203 and the input end of the generator 1 to rotate clockwise, and the generator 1 generates electricity. When the large gear 1 201 and the large gear 2 202 rotate counterclockwise, the driven gear ring 302 in the one-way rotating flywheel 1 rotates counterclockwise. 02 rotates clockwise, thereby driving the pawl 303 and the center wheel 301 to rotate clockwise, driving the drive shaft 203 and the input end of the generator 1 to rotate clockwise, and the generator 1 generates electricity. The driven gear ring 302 in the unidirectional rotating flywheel 2 rotates counterclockwise, and the center wheel 301 does not rotate, so that the drive shaft 203 always rotates clockwise, and the generator 1 generates electricity continuously. Two groups of float groups drive the same rotating shaft 103 and the generator 1. The device has a total of four groups of float groups, which drive the two generators 1 to generate electricity. The generator 1 is connected to a compatible power storage device such as a battery to store the electrical energy generated by the generator 1 in the battery.

[0067] like Fig. 9As shown, in order to realize the transmission connection between the one-way rotating flywheel 2 and the large gear 202, the transmission member includes a driving gear 401, a transmission gear 402, a synchronous bevel gear 403 and a transmission bevel gear 404. The driving gear 401 is rotatably set on the platform 2, and the driving gear 401 is rotatably set on the support frame 3 through a rotating ring. The driving gear 401 is meshed with the large gear 202. There are two transmission gears 402, and the transmission gear 402 is rotatably set on the platform 2 through a rotating rod. The two transmission gears 402 are respectively meshed with the driving gear 401 and the driven gear ring 302 in the one-way rotating flywheel 2. There are two synchronous bevel gears 403, and the two synchronous bevel gears 403 are respectively coaxially set at one end of the two transmission gears 402 close to each other. The transmission bevel gear 404 is rotatably set on the platform 2, and the transmission bevel gear 404 is located between the two synchronous bevel gears 403. The transmission bevel gear 404 is meshed with the two synchronous bevel gears 403, and the synchronous bevel gears 403 and the transmission bevel gear 404 are both rotatably set on the support frame 3. On the upper side, the large gear 202 drives the driving gear 401 to rotate, the driving gear 401 drives the transmission gear 402 meshing therewith to rotate, the transmission gear 402 drives the synchronous bevel gear 403 to rotate, and under the action of the transmission bevel gear 404, another synchronous bevel gear 403 and another transmission gear 402 are driven to rotate, thereby driving the driven gear ring 302 in the one-way rotating flywheel 2 to rotate, the two synchronous bevel gears 403 are symmetrical with respect to the transmission bevel gear 404, and the two transmission bevel gears 404 rotate in opposite directions, and the driving gear The wheel 401 and the large gear 202 rotate in opposite directions, so that the driven gear ring 302 of the unidirectional rotating flywheel 2 rotates in the same direction as the large gear 202. The diameter and number of teeth of the driving gear 401 and the driven gear ring 302 are the same. The diameter ratio of the large gear 1 201 to the driving gear 401 and the driven gear ring 302 is 12:1. When the large gear 1 201 and the large gear 2 202 swing slightly (about 30 degrees), the driving gear 401 or the driven gear ring 302 can be driven to rotate one circle, so that the generator 1 generates electricity.

[0068] like Figures 1 to 10 As shown, the protection component is used to protect the one-way transmission component, and the protection component includes a protection cover 501, which is arranged on the platform 2, and the large gear 1 201, the large gear 202, the one-way rotating flywheel 1 and the one-way rotating flywheel 2 are all located inside the protection cover 501, and the driving shaft 203 and the rotating shaft 103 are both rotated in cooperation with the protection cover 501. The protection cover 501 can protect the large gear 1 201, the large gear 202, the one-way rotating flywheel 1 and the one-way rotating flywheel 2 to prevent seawater from entering and corroding them, thereby ensuring the precise meshing between the gears and reducing energy loss.

[0069] like Fig.10As shown, in order to further reduce the corrosion of the one-way transmission component, a lubrication component is also included, which is used to lubricate the one-way transmission component. The lubrication component includes a conveying bin 601, a conveying plate 602, a reciprocating screw 603, an oil inlet pipe 604 and an oil outlet pipe 605. The conveying bin 601 is set on the platform 2, the conveying plate 602 is sealed and slidably set inside the conveying bin 601, the reciprocating screw 603 is rotatably set inside the conveying bin 601, the conveying plate 602 and the reciprocating screw 603 are threadedly connected, and the reciprocating screw 603 and the drive shaft are connected. 203 transmission connection, the reciprocating screw 603 is coaxially connected with a transmission rod 606, and the transmission rod 606 is transmission-connected to the drive shaft 203 through a sprocket chain, two oil inlet pipes 604 are provided, the two oil inlet pipes 604 are connected to both sides of the delivery bin 601, a one-way valve 607 is provided on the oil inlet pipe 604, the oil inlet pipe 604 is connected to the bottom of the protective cover 501, and two oil outlet pipes 605 are provided, the two oil outlet pipes 605 are connected to both sides of the delivery bin 601, a one-way valve 607 is provided on the oil outlet pipe 605, and the oil outlet pipe 605 is connected to the bottom of the protective cover 501. The top of the protective cover 501 is connected. When the waves drive the buoy 101 and the buoy 2 102 to swing up and down, the driving shaft 203 is driven to rotate under the action of the one-way transmission component, and the reciprocating screw 603 is driven to rotate under the transmission action of the sprocket chain, so that the conveying plate 602 reciprocates inside the conveying bin 601. When the conveying plate 602 moves, the pressure on the side away from the moving direction decreases, and the lubricating oil at the bottom of the protective cover 501 is sucked into the inside of the conveying bin 601. Under the action of the one-way valve 607, the oil outlet pipe 60 on this side is 5 is in a closed state. During the movement of the conveying plate 602, the lubricating oil in the moving direction is squeezed out from the oil outlet pipe 605 to the upper position inside the protective cover 501, that is, sprayed on the surface of the transmission bevel gear 404, the synchronous bevel gear 403 or the one-way rotating flywheel 1. Under the action of the one-way valve 607, the oil inlet pipe 604 on this side is in a closed state. The lubricating oil falls under the action of gravity to lubricate the large gear 1 201 or the large gear 2 202 and other components, thereby reducing the energy loss of the transmission between the gears. The lubricating oil falls and is recycled.

[0070] Embodiment 2: This embodiment proposes a method for generating electricity based on sea wave floating, using the sea wave floating generating device in Embodiment 1, and comprising the following steps:

Driven by the waves, buoy 101 and buoy 2 102 will swing up and down on the sea surface with rotating shaft 103 as the center. During the swinging process, buoy 101 and buoy 2 102 will drive large gear 1 201 and large gear 2 202 to rotate slightly left and right.

[0073] S3, when the large gear 1 201 and the large gear 2 202 rotate counterclockwise, the driven gear ring 302 of the one-way rotating flywheel 1 rotates clockwise, pushing the pawl 303 and the center wheel 301 to rotate clockwise, and the driven gear ring 302 of the one-way rotating flywheel 2 rotates counterclockwise, and the center wheel 301 is in a stopped state;

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
