Energy storage magnetic blade tidal current power generation device

Abstract

This invention relates to an energy storage-type magnetic blade tidal current power generation device, comprising a support column and multiple rotating components. A power generation structure is mounted at one end of the support column, and an energy storage structure, including a speed sensor, is mounted at the other end. Each rotating component is connected to both the power generation and energy storage structures. A blade assembly is fitted onto the rotating component, and multiple magnetic blades facing the same direction are mounted circumferentially on the blade assembly. The multiple rotating components are spaced apart circumferentially along the outer ring of the support column, with the magnetic blades on adjacent rotating components facing opposite directions. At high water flow velocities, the magnetic blades, due to their identical magnetic fields, rotate faster due to magnetic repulsion, improving power generation efficiency and driving the energy storage structure to store kinetic energy. At low water flow velocities, the energy storage structure reverses direction, driving the rotating components to rotate and ensuring the device's self-starting capability. This device offers higher power generation efficiency and stronger self-starting capability at low flow rates compared to traditional devices.

[0001] The present application relates to the technical field of tidal current power generation equipment, in particular to a tidal current power generation device with energy storage and magnetic blades. BACKGROUND

[0002] With the progress of science and technology, a variety of underwater robots and unmanned underwater vehicles have been developed in the world today to explore the underwater world, and the underwater base station that supplies energy to them has also emerged accordingly.

[0003] Because the seabed environment is very special, if the underwater base station is powered by a power generation structure on land, a large number of submarine cables need to be manufactured, which is extremely costly and difficult to maintain. Therefore, for the underwater base station located on the seabed, a corresponding tidal current power generation device is generally used to provide energy for the underwater base station.

[0004] Traditional tidal current power generation devices are generally divided into horizontal axis type and vertical axis type, among which the horizontal axis type tidal current power generation device is not suitable for the seabed where the water flow direction is mainly horizontal flow, and the vertical axis type tidal current power generation device, although it does not limit the water flow direction, has the disadvantages of small starting torque and poor self-starting ability at low flow rate. SUMMARY

[0005] Therefore, it is necessary to provide a tidal current power generation device with energy storage and magnetic blades, which has higher power generation efficiency and stronger self-starting ability at low flow rate compared to traditional vertical axis type tidal current power generation devices.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0046] The following is combined with Figures 1-12 This invention describes an energy storage magnetic blade tidal current power generation device.

[0047] like Figure 1 As shown, in one embodiment, an energy storage type magnetic blade tidal power generation device includes a support column 100 and multiple rotating components 400. Each rotating component 400 is equipped with a blade assembly 500, the blades on the blade assembly 500 having the same orientation and all being magnetic blades 520. A power generation structure 200 is mounted at one end of the support column 100, and an energy storage structure 300 is mounted at the other end. The energy storage structure 300 includes a speed sensor 330. One end of each rotating component 400 is connected to the power generation structure 200, and the other end is connected to the energy storage structure 300. The multiple rotating components 400 are spaced apart circumferentially along the outer ring of the support column 100, and the magnetic blades 520 of the blade assemblies 500 on every two adjacent rotating components 400 have opposite orientations.

[0048] Specifically, the power generation structure 200 uses an electric motor 210 and a battery 230. The electric motor 210 rotates with the rotating component 400 to generate electrical energy, which is then transmitted to the battery 230 through wires. The energy storage structure 300 can use a spring mechanism for mechanical energy storage. When the rotation speed of the rotating component 400 is higher than a first threshold, the rotating component 400 rotates and drives the spring 3134 to tighten. At this time, the spring 3134 stores elastic potential energy. When the rotation speed of the rotating component 400 is lower than the first threshold, the tightened spring 3134 reverses and releases potential energy to drive the rotating component 400 to rotate. The magnetic blades 520 can be made by embedding magnets on the outside of the blades, with the N pole and S pole of the magnets on the blades distributed outward in sequence. This allows the magnetic blades 520 on two adjacent blade assemblies 500 to rotate faster due to the same magnetic field and mutual magnetic repulsion.

[0049] It should be noted that, under normal circumstances, the reversal of the mainspring mechanism will cause the rotating component 400 to reverse, which will cause the blades to come into contact with the water flow and reduce the rotation speed. Therefore, a reversing shaft needs to be set in the mainspring mechanism to ensure that the rotation direction of the rotating component 400 remains unchanged when the mainspring mechanism drives the rotating component 400 to rotate.

[0050] The aforementioned energy storage-type magnetic blade tidal current power generation device connects the two ends of the rotating component 400 to the power generation structure 200 and the energy storage structure 300, respectively. Magnetic blades 520 are installed on the rotating component 400 to capture energy. When the water flow velocity is high, the magnetic blades 520 on adjacent rotating components 400, due to their identical magnetic fields, repel each other, accelerating the rotation of the rotating component 400 and improving the power generation efficiency of the power generation structure 200. Simultaneously, the rotation drives the energy storage structure 300 to store kinetic energy. When the water flow velocity is low, the energy storage structure 300 reverses direction, thereby driving the rotating component 400 to rotate, ensuring the self-starting capability of the power generation structure 200 at low water flow velocities. This device has higher power generation efficiency and stronger self-starting capability at low flow velocities compared to the traditional vertical axis tidal current power generation device 200.

[0051] like Figure 2 As shown, in this embodiment, the blade assembly 500 further includes a support portion 510, which is splined and fitted onto the rotating assembly 400. Multiple magnetic blades 520 are circumferentially spaced on the support portion 510, and are rotatably connected to it. Specifically, the magnetic blades 520 are rotatably mounted on the side wall of the support portion 510, forming a certain angle between them to increase the contact area between the magnetic blades 520 and the water flow, thereby improving energy capture efficiency.

[0052] In this embodiment, the blade assembly 500 also includes a telescopic rod 530, one end of which is connected to the support portion 510, and the other end is connected to the magnetic blade 520. Specifically, the telescopic rod 530 is adjustable in length, with one end connected to the support portion 510 and the other end connected to the magnetic blade 520. When the telescopic rod 530 extends, the other end of the telescopic rod 530 pushes the magnetic blade 520 away, increasing the angle between the magnetic blade 520 and the support portion 510, thereby increasing the contact area between the magnetic blade 520 and the water flow, thus increasing the rotational speed and improving the energy capture efficiency of the device. When the water flow velocity is too high, in order to prevent the system from overloading due to excessively high power generation efficiency, the length of the telescopic rod 530 is shortened to reduce the angle between the magnetic blade 520 and the support portion 510, thereby reducing the rotational speed and protecting the system.

[0053] like Figure 3 As shown, in this embodiment, the rotating assembly 400 includes a rotating rod 410 and a rotating sleeve 420, wherein one end of the rotating rod 410 is connected to the power generation structure 200 and the other end is connected to the energy storage structure 300; the rotating sleeve 420 is sleeved on the rotating rod 410 by spline engagement, and a support portion 510 is sleeved on the outer ring of the rotating sleeve 420.

[0054] Specifically, the two ends of the rotating rod 410 pass through the two ends of the support column 100 and are respectively connected to the power generation structure 200 and the energy storage structure 300. The rotating rod 410, the rotating sleeve 420 and the support part 510 are connected from the inside to the outside by spline engagement, thereby ensuring that the blade assembly 500 drives the rotating component 400 to rotate synchronously and coaxially.

[0055] like Figure 1 and Figure 3As shown, in this embodiment, the rotating assembly 400 further includes a hydraulic device 430, which is connected to one end of the rotating sleeve 420 and is used to push the rotating sleeve 420 to move axially along the rotating rod 410. Specifically, one end of the hydraulic device 430 is connected to one end of the rotating sleeve 420, and the other end can be set on one end of the support column 100. When the water flow rate is low, the magnetic blades 520 on the rotating assembly 400 rotate slowly. Since the blades are magnetic, the magnetic blades 520 on two adjacent rotating assemblies 400 will generate a force that hinders rotation during rotation. Since the rotation speed is low at this time, it is impossible to counteract the force that hinders rotation. By configuring the hydraulic device 430, when the speed sensor 330 detects a low rotational speed, the hydraulic device 430 pushes two adjacent rotating sleeves 420 to different positions to increase the distance between the magnetic blades, thereby eliminating the magnetic resistance. When the speed sensor 330 detects that the rotational speed has recovered, the hydraulic device 430 pulls the two adjacent rotating sleeves 420 back to the same position, causing the magnetic blades to move closer together and generate vortex assistance, thereby increasing the blade rotational speed. To ensure that the rotating sleeves 420 can still rotate when the hydraulic device 430 is in operation, thrust bearings can be installed at both ends of the rotating sleeves 420.

[0056] It should be noted that the hydraulic device 430 can be installed on the rotating sleeve 420 at intervals. For example, only the rotating sleeve 420 in the opposite direction can be connected to the hydraulic device 430, and the rotating sleeve 420 in the opposite direction can be pushed upward by the hydraulic device 430. This can also increase the distance between the magnetic blades 520 on the adjacent rotating components 400, thereby eliminating the obstruction of magnetic force and saving device costs and reducing manufacturing difficulty.

[0057] like Figure 4 and Figure 5 As shown, in this embodiment, the energy storage structure 300 also includes an energy storage cover 320 and multiple gearboxes 310. The gearboxes 310 are connected to the other end of the rotating assembly 400. A spring 3134 is installed inside the gearboxes 310, which converts kinetic energy into potential energy and stores it. The energy storage cover 320 is installed at one end of the support column 100, and the gearboxes 310 are housed within the energy storage cover 320. Specifically, the energy storage cover 320 is hollow inside and installed at one end of the support column 100 to isolate the water flow and protect the gearboxes 310. Each gearbox 310 corresponds to one of the rotating assemblies 400. When the water flow velocity is high, the spring 3134 tightens and deforms during the rotation of the rotating assembly 400, storing elastic potential energy. When the water flow velocity is low, the spring 3134 releases energy, driving the rotating assembly 400 to rotate. To ensure that the rotation direction of the rotating assembly 400 remains unchanged when the spring 3134 releases energy, a direction-changing structure is required.

[0058] In this embodiment, the gearbox 310 includes a vertical bevel gear 3111 and a horizontal bevel gear 3121, which are perpendicular to each other and meshed for transmission. Specifically, through the transmission action of the vertical bevel gear 3111 and the horizontal bevel gear 3121, the vertical transmission of the rotating shaft is converted into a horizontal transmission, allowing the gear set and the mainspring 3134 inside the gearbox 310 to be placed horizontally, thereby ensuring greater structural stability.

[0059] It should be noted that, due to the working principle of the mainspring 3134, in order to prevent the rotating component 400 from reversing and affecting the power generation efficiency, this embodiment provides an internal structure of the gearbox 310 as follows: Figures 5 to 9 As shown, the gearbox 310 includes a first bevel gear set 311, a second bevel gear set 312, a first gear set 313, a transmission gear set 314, a second gear set 315, and a frame 316.

[0060] The first bevel gear set 311 includes a vertical bevel gear 3111, a vertical synchronizing ring 3112, and a transmission gear 3113. The vertical bevel gear 3111 and the vertical synchronizing ring 3112 are mounted on the first bevel gear shaft and rotate coaxially. The transmission gear 3113 is connected to the other end of the rotating assembly 400 and rotates coaxially with the rotating assembly 400. The vertical synchronizing ring 3112 can move vertically along the first bevel gear shaft. When the vertical synchronizing ring 3112 is at the bottom, it connects the vertical bevel gear 3111 and the transmission gear 3113, and the rotating assembly 400 drives the vertical bevel gear 3111 to rotate. When the vertical synchronizing ring 3112 is at the top, the vertical bevel gear 3111 is disconnected from the transmission gear 3113, and the vertical bevel gear 3111 does not rotate. The first bevel gear shaft passes through the frame 316, and the vertical bevel gear 3111 is mounted on the top of the frame 316.

[0061] The second bevel gear set 312 includes a horizontal bevel gear 3121 and a cylindrical gear 3122. The horizontal bevel gear 3121 and the cylindrical gear 3122 are mounted on the second bevel gear shaft and rotate coaxially.

[0062] The second gear set 315 includes a second reversing gear 3151, a reduction gear 3152, and an energy-releasing gear 3153. The second reversing gear 3151, the reduction gear 3152, and the energy-releasing gear 3153 are mounted on the second gear shaft and rotate coaxially. The energy-releasing gear 3153 is externally meshed with the cylindrical gear 3122 for transmission.

[0063] The first gear set 313 includes a first connecting gear 3131, a horizontal synchronizing ring 3132, a second connecting gear 3133, and a spring 3134. The horizontal synchronizing ring 3132, the second connecting gear 3133, and the spring 3134 are coaxially mounted on the first gear shaft and rotate together. The first connecting gear 3131 is mounted on the first gear shaft via a self-aligning ball bearing and meshes externally with the reduction gear 3152. The horizontal synchronizing ring 3132 can move horizontally along the first gear shaft. When the horizontal synchronizing ring 3132 moves to the left, it connects the first connecting gear 3131 and the second connecting gear 3133. When the horizontal synchronizing ring 3132 moves to the right, it disconnects the first connecting gear 3131 from the second connecting gear 3133.

[0064] The transmission gear set 314 includes a first reversing gear 3141, which is sleeved on the shaft of the transmission gear 3113 and rotates coaxially. One side of the first reversing gear 3141 meshes with the second reversing gear 3151, and the other side meshes with the second connecting gear 3133.

[0065] The second bevel gear shaft, the first gear shaft, the second gear shaft, and the transmission gear 3113 shaft are rotatably mounted on the frame 316 via self-aligning ball bearings.

[0066] Based on the above structure, the energy storage process of the energy storage structure 300 is as follows: the vertical synchronous ring moves downward and the horizontal synchronous ring moves to the left. At this time, the vertical synchronous ring connects the transmission gear 3113 and the vertical bevel gear 3111, and the horizontal synchronous ring connects the first connecting gear 3131 and the second connecting gear 3133. The rotating component 400 rotates in contact with the water flow, driving the transmission gear 3113 to rotate. The vertical bevel gear 3111 rotates coaxially with the transmission gear 3113, and transmits the energy sequentially to the horizontal bevel gear 3121, the cylindrical gear 3122, the energy-releasing gear 3153, the reduction gear 3152, the first connecting gear 3131, and the second connecting gear 3133, thereby driving the spring 3134 to rotate and store energy. Among them, the radius of the reduction gear 3152 is smaller than the radius of the first connecting gear 3131 to prevent the spring 3134 from being damaged when the rotating component 400 rotates too fast.

[0067] Based on the above structure, the energy release process of the energy storage structure 300 is as follows: When the rotating component 400 rotates at a low speed or even stops, the vertical synchronizing ring moves downward and the horizontal synchronizing ring moves to the right. The vertical synchronizing ring connects the transmission gear 3113 and the vertical bevel gear 3111, and the first connecting gear 3131 and the second connecting gear 3133 are disconnected. At this time, the spring 3134 releases energy, driving the second connecting gear 3133 to rotate, and then sequentially transmits the energy to the first reversing gear 3141, the second reversing gear 3151, the energy-releasing gear 3153, the cylindrical gear 3122, the horizontal bevel gear 3121, and the vertical bevel gear 3111, and then drives the rotating component 400 to resume rotation through the transmission gear 3113. Specifically, based on the principle that the spring 3134 reverses direction when releasing energy, the first reversing gear 3141 and the second reversing gear 3151 are set to prevent the rotating component 400 from reversing direction and affecting the power generation efficiency.

[0068] When the energy of the mainspring 3134 is fully released and the rotation speed of the rotating component 400 is still low, the vertical synchronizing ring is moved upward, and the transmission gear 3113 is disconnected from the vertical bevel gear 3111.

[0069] like Figure 3 and Figure 10 As shown, in this embodiment, magnetic levitation components 440 are respectively provided at both ends of the rotating component 400, and the rotating component 400 is fixedly connected to the support column 100 through the magnetic levitation components 440. Specifically, annular permanent magnets are fixed at both ends of the rotating rod 410, and a levitation cover is wrapped around the outside of the annular permanent magnet. A sheet permanent magnet is pasted inside the levitation cover, and the annular permanent magnet and the sheet permanent magnet are kept in a gap fit state under the action of magnetic force; the levitation cover is engaged with the end of the support column 100 and sealed and fixed by a sealing cover. The magnetic levitation structure reduces the friction between the rotating component 400 and the support column 100 during the rotation process, thereby improving the power generation efficiency.

[0070] like Figure 11 As shown, in this embodiment, the power generation structure 200 includes a motor 210, an accelerator 220, a battery 230, and a power generation cover 240. The accelerator 220 rotates coaxially with one end of the rotating assembly 400. The motor 210 is connected to the accelerator 220. The battery 230 is connected to the motor 210 through a wire. The power generation cover 240 is installed at the other end of the support column 100. The motor 210, the accelerator 220, and the battery 230 are located inside the power generation cover 240.

[0071] like Figure 12As shown, in this embodiment, the accelerator 220 includes a first accelerating wheel 221, a first transmission wheel 222, a second accelerating wheel 223, and a second transmission wheel 224. One end of the rotating assembly 400 of the first accelerating wheel 221 is coaxially rotatably connected; the first transmission wheel 222 is externally meshed with the first accelerating wheel 221; the second accelerating wheel 223 rotates coaxially with the first transmission wheel 222; the second transmission wheel 224 is externally meshed with the second accelerating wheel 223 and connected to the motor 210; the radius of the first accelerating wheel 221 is larger than that of the first transmission wheel 222, and the radius of the second transmission wheel 224 is larger than that of the second accelerating wheel 223.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
