Description

Technical Field

[0001] This invention relates to the field of hydropower generation, and in particular to an omnidirectional water wave energy harvesting and power generation device and an array generator set. Background Technology

[0002] Water wave energy, or simply wave energy, is one of the most important energy sources in the ocean. With the increasing number of electrical devices, human demand for electricity is also gradually increasing. It is an easily accessible, inexhaustible, and renewable clean energy source. Seawater is composed of countless particles. Under the influence of external forces, these particles move periodically around their equilibrium points, forming waves. Tidal movements or wind can cause the seawater particles to shift relative to the sea surface, giving the waves potential energy. The movement of the seawater particles, in turn, gives the waves kinetic energy.

[0003] Wave energy is a clean energy source that can be harvested for power generation. Wave energy power generation consists of two parts: energy harvesting and energy conversion. The harvesting device captures wave energy, while the energy conversion device converts the harvested wave energy into some form of mechanical or electrical energy. Existing wave energy harvesting devices are typically underwater gear-driven devices that utilize the water flow generated by the waves to drive the corresponding gear mechanism to rotate, thereby collecting its kinetic energy for power generation.

[0004] Existing conventional wave energy harvesting devices, being entirely underwater, are susceptible to seawater erosion after prolonged operation, resulting in a short lifespan. Furthermore, underwater currents typically only provide lateral wave energy, while a significant amount of longitudinal wave energy exists on the surface due to wave undulations. Existing wave energy harvesting devices lack effective means to absorb this longitudinal wave energy, leading to low harvesting efficiency. Summary of the Invention

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] Existing wave energy harvesting devices are typically underwater gear-driven devices that use the water flow generated by waves to drive the corresponding gear mechanism to rotate, thereby collecting its kinetic energy for power generation.

[0039] Existing conventional wave energy harvesting devices, being entirely underwater, are susceptible to seawater erosion after prolonged operation, resulting in a short lifespan. Furthermore, underwater currents typically only provide lateral wave energy, while a significant amount of longitudinal wave energy exists on the surface due to wave undulations. Existing wave energy harvesting devices lack effective means to absorb this longitudinal wave energy, leading to low harvesting efficiency.

Figures 1 to 11 As shown in the figure, through practice, the present invention provides an omnidirectional water wave energy harvesting and power generation device and an array generator set, including: a collection end 1, a power generation end 2 and a base plate 3, wherein the collection end 1 and the power generation end 2 are both disposed on the base plate 3.

[0041] The collecting end 1 includes a float 11, a connecting rod 12, a first universal joint mechanism 13 fixedly mounted on the base plate, a transmission assembly 14, a longitudinal water pump unit 15, and a transverse water pump unit 16.

[0042] The float 11 floats on the water surface. The first universal joint mechanism 13 includes a circular plate 131, a circular ring 132, a longitudinal pin 133, a transverse pin 134, and a universal bracket 135. The circular plate 131 is rotatably connected to the circular ring 132 through the longitudinal pin 133. The circular ring 132 is rotatably connected to the universal bracket 135 through the transverse pin 134. The transverse pin 134 is parallel to the bottom plate 3. The float 11 is connected to one side of the circular plate 131 through the connecting rod 12. The transmission assembly 14 is connected to the other side of the circular plate 131.

[0043] For example, the universal joint 135 is fixed to the base plate 3 by stiffeners. The universal joint 135 and the ring 132 form a revolute joint through the horizontal pin 134. The ring 132 and the circular plate 131 form a revolute joint through the vertical pin 133. When the float 11 receives water wave energy from the lateral direction, the water wave energy drives the float 11 to move horizontally, thereby driving the connecting rod 12 and the circular plate 131 to move horizontally. Under the constraint of the first universal joint mechanism 13, the circular plate 131 rotates along the axis of the vertical pin 133, thereby driving the transmission assembly 14 to move horizontally. When the float 11 receives water wave energy from the longitudinal direction, the water wave energy drives the float 11 to move perpendicular to the water surface, thereby driving the connecting rod 12 and the circular plate 131 to move perpendicular to the water surface. Under the constraint of the first universal joint mechanism 13, the circular plate 131 rotates along the axis of the horizontal pin 134, thereby driving the transmission assembly 14 to move perpendicular to the water surface.

[0044] The longitudinal pump unit 15 includes a longitudinal piston pump 151, a first three-way pipe 152, and a piston rod 153. The longitudinal piston pump 151 is perpendicular to the base plate 3. The piston rod 153 is connected to the first piston 1511 inside the longitudinal piston pump 151. One end of the first three-way pipe 152 is connected to the longitudinal piston pump 151, and the second end of the first three-way pipe 152 is connected to the water surface. The transverse pump unit 16 includes a transverse piston pump 161, a second three-way pipe 162, and a piston rod 163. The transverse piston pump 161 is parallel to the base plate 3. The piston rod 163 is connected to the second piston 1611 inside the transverse piston pump 161. One end of the second three-way pipe 162 is connected to the transverse piston pump 161, and the second end of the second three-way pipe 162 is connected to the water surface.

[0045] The transmission assembly 14 is configured to drive the piston rod 153 to move in a direction perpendicular to the base plate 3 based on the rotation of the ring 132; or, to drive the piston rod 163 to move in a direction parallel to the base plate 3 based on the rotation of the circular plate 131.

[0046] Exemplarily, in this embodiment of the invention, the second and third ends of the first three-way pipe 152 and the second three-way pipe 162 are provided with one-way valves 6. The one-way valves 6 face the same direction and are configured such that water can only flow from the second end into the cavity, and water can only flow from the cavity to the third end. When the longitudinal water wave energy drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 153 to drive the first piston 1511 to move in a direction away from the first three-way pipe 152, a negative pressure is generated in the longitudinal piston pump 151 cavity. Under the action of the external water pressure, water enters the piston rod 153 from the second end of the first three-way pipe 152 through the one-way valve 6. When the piston rod 153 drives the first piston 1511 to move in a direction close to the first three-way pipe 152, the volume of the longitudinal piston pump 151 cavity is compressed. Under the action of pressure, water enters the inlet 211 of the water flow generator 21 from the third end of the first three-way pipe 152 through the one-way valve 6. When the energy of the transverse water wave drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 163 to drive the second piston 1611 to move in a direction away from the second three-way pipe 162, a negative pressure is generated in the chamber of the transverse piston pump 161. Under the action of the external water pressure, the water enters the piston rod 163 from the second end of the second three-way pipe 162 through the one-way valve 6. When the piston rod 163 drives the second piston 1611 to move in a direction close to the second three-way pipe 162, the volume of the chamber of the transverse piston pump 161 is compressed. Under the action of pressure, the water enters the inlet 211 of the water flow generator 21 from the third end of the second three-way pipe 162 through the one-way valve 6.

[0047] The power generation end 2 is a water flow generator 21, and the water inlet 211 of the water flow generator 21 is connected to the third end of the first three-way pipe 152 and the third end of the second three-way pipe 162.

[0048] For example, in an embodiment of the present invention, the water flow generator 21 further includes a water collection tank 212, a water injection pipe 213, a water tank bracket 214, a housing 215, blades 216, an impeller 217, a shaft support 218, a large synchronous pulley 219, a synchronous belt 220, a small synchronous pulley 221, a coupling 222, a generator 223, a generator bracket 224, an energy storage module 225, and a water outlet 226. The energy storage module 225 is fixed on the base plate 3 and electrically connected to the generator 223. The generator 223 is fixed on the base plate 3 via the generator bracket 224. A coupling 222 is installed on the shaft of the generator 223. A small synchronous pulley 221 is installed at the end of the shaft of the generator 223. The housing 215 is fixedly installed on the base plate 3. An impeller 217 is fixedly installed inside the housing 215. Blades 216 are fixedly installed on the impeller 217. The output shafts on both sides of the impeller 217 are installed on the shaft support 218. The shaft support 218 is fixedly connected to the two end faces of the housing 215. One output shaft of the impeller 217 is connected to the large synchronous pulley 219. The large synchronous pulley 219 and the small synchronous pulley 221 are connected via a synchronous belt 220. A water tank bracket 214 is fixedly mounted on the top of the casing 215. A water collection tank 212 is mounted on the top of the casing 215 via the water tank bracket 214 and is connected to the interior of the casing 215 via a water inlet pipe 213. Water collected from the third end of the first three-way pipe 152 and the second three-way pipe 162 enters the water collection tank 212 through the inlet 211. The water then flows into the casing 215 through the water collection tank 212 and the water inlet pipe 213, causing the blades 216, impeller 217, and large synchronous pulley 219 to rotate. The water then flows out through the outlet 226 of the casing, which in turn drives the synchronous belt 220, small synchronous pulley 221, and coupling 222 to rotate, transmitting the rotational power to the generator 223 to generate electricity. Finally, the generated electrical energy is stored through the energy storage module 225. Through this coordinated movement, the generator end 2 effectively converts the kinetic energy of the water collected at the collection end 1 into electrical energy and stores it.

[0049] Compared to existing water wave energy harvesting devices, which are typically underwater gear transmission devices that use the water flow generated by waves to drive the corresponding gear mechanism to rotate and only collect lateral water wave energy for power generation, the omnidirectional water wave energy harvesting and power generation device and array generator set provided in this embodiment of the invention can collect lateral and longitudinal water wave energy through float 11, connecting rod 12, universal joint mechanism 13, transmission component 14, longitudinal water pump unit 15 and lateral water pump unit 16, thereby driving the water flow generator 21 to generate electricity. It can realize the collection and utilization of lateral and longitudinal water wave energy, improve the utilization rate of water wave energy harvesting and power generation system, and effectively solve the problem of low water wave energy harvesting efficiency in the prior art.

[0050] Compared to existing water wave energy harvesting devices that are typically located underwater, the components of the omnidirectional water wave energy harvesting and power generation device and array generator set provided in this embodiment of the invention are all located above the water surface, which reduces the corrosion of components by water and increases the service life of the omnidirectional water wave energy harvesting and power generation device.

[0051] Optionally, two first three-way pipes 152 are provided and disposed on both sides of the first piston 1511; two second three-way pipes 162 are provided and disposed on both sides of the second piston 1611. Exemplarily, in this embodiment of the invention, the first piston 1511 divides the longitudinal piston pump 151 into a first chamber 1512 and a second chamber 1513, and the second piston 1611 divides the transverse piston pump 161 into a third chamber 1612 and a fourth chamber 1613. When the longitudinal water wave energy drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 153 to drive the first piston 1511 to move and thus enlarge the first chamber 1512, a negative pressure is generated in the first chamber 1512. Water enters the first chamber 1512 through the first three-way pipes 152 within the first chamber 1512. The volume of the second chamber 1513 is compressed, and water enters the inlet 211 through the first three-way pipes 152 within the second chamber 1513. When the longitudinal water wave energy drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 153 to drive the first piston 1511 to move and making the second chamber 1513 larger, a negative pressure is generated in the second chamber 1513. Water enters the second chamber 1513 through the first three-way pipe 152 in the second chamber 1513. The volume of the first chamber 1512 is compressed, and water enters the inlet 211 through the first three-way pipe 152 in the first chamber 1512. When the lateral water wave energy drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 163 to drive the second piston 1611 to move, thus expanding the third chamber 1612, a negative pressure is generated in the third chamber 1612. Water enters the third chamber 1612 through the second three-way pipe 162, compressing the volume of the fourth chamber 1613. Water then enters the inlet 211 through the second three-way pipe 162 within the fourth chamber 1613. Similarly, when the lateral water wave energy drives the first universal joint mechanism 13 and the transmission assembly 14 to move, causing the piston rod 163 to drive the second piston 1611 to move, thus expanding the fourth chamber 1613, a negative pressure is generated in the fourth chamber 1613. Water then enters the fourth chamber 1613 through the second three-way pipe 162, compressing the volume of the third chamber 1612. By setting two first three-way pipes 152 on both sides of the first piston 1511 and two second three-way pipes 162 on both sides of the second piston 1611, the efficiency of water flow can be increased several times, the water flow rate entering the inlet 211 can be increased, thereby increasing the power generation efficiency of the omnidirectional water wave energy harvesting and power generation device.

[0052] Optionally, a water intake hole 31 is provided on the base plate 3, and the second end of the first three-way pipe 152 and the second end of the second three-way pipe 162 are connected to the water surface through the water intake hole 31. For example, an elongated water intake hole 31 is provided directly below the longitudinal piston pump 151 on the base plate 3, which reduces the distance between the second end of the first three-way pipe 152 and the second end of the second three-way pipe 162 and the water surface, thereby improving the working efficiency of the longitudinal water pump unit 15 and the transverse water pump unit 16, and further increasing the power generation efficiency of the omnidirectional water wave energy harvesting and power generation device.

[0053] Optionally, the transmission assembly 14 includes a slider guide rod 141, a slider 142, a slider connecting rod 143, a second universal joint mechanism 144, a slider plate 145, and a longitudinal guide rail 146. One end of the slider guide rod 141 is fixedly connected to the center of the circular plate 131. The slider 142 is slidably mounted on the slider guide rod 141. One end of the slider 142 is fixedly connected to the slider connecting rod 143. The other end of the slider connecting rod 143 is fixedly connected to one end of the second universal joint mechanism 144. The other end of the second universal joint mechanism 144 is connected to the slider plate. The system is connected by a 145-145 connection. The longitudinal guide rail 146 is vertically and slidably mounted on the base plate 3. The longitudinal guide rail 146 is fixedly connected to the longitudinal piston pump 151. The piston vertical rod 153 is parallel to the longitudinal guide rail 146. The slider plate 145 is fixedly connected to the piston vertical rod 153. The slider plate 145 is slidably mounted on the longitudinal guide rail 146. The piston horizontal rod 163 is mounted on the base plate 3 parallel to the sliding direction of the longitudinal guide rail 146. The transverse piston pump 161 is fixedly mounted on the base plate 3. The longitudinal guide rail 146 is fixedly connected to the piston horizontal rod 163.

[0054] For example, in an embodiment of the present invention, the transmission assembly 14 further includes a right universal joint 1441, a cross joint 1442, a left universal joint 1443, a horizontal guide rail 7, a horizontal slider 71, a lower plate 72, a vertical plate 73, an upper plate 74, a vertical slider 1461, a first protrusion 1531, a second protrusion 1631, and a horizontal plate 75.

[0055] One end of the slider guide rod 141 is fixedly connected to the center of the circular plate 131. The slider 142 is slidably mounted on the slider guide rod 141. When the water wave energy drives the first universal joint mechanism 13 to rotate through the float 11 and the connecting rod 12, the slider 142 can move along the slider guide rod 141. One end of the slider 142 is fixedly connected to the slider connecting rod 143. The other end of the slider connecting rod 143 is fixed to the right universal joint 1441. The right universal joint 1441 and the left universal joint 1443 form the second universal joint mechanism 144 through the cross 1442. The second universal joint mechanism 144 is connected to the slider plate 145, so that when the circular plate 131 rotates about the horizontal pin 134 as the axis, the slider plate 145 can move longitudinally, and when the circular plate 131 rotates about the vertical pin 133 as the axis, the slider plate 145 can move laterally.

[0056] A horizontal guide rail 7 is provided on both sides of the water intake hole 31. A horizontal slider 71 is slidably mounted on the horizontal guide rail 7. A lower plate 72 is fixedly mounted on the horizontal slider 71. A vertical plate 73 is vertically fixedly mounted on the lower plate 72 by means of a rib. A longitudinal piston pump 151 is fixedly connected to the vertical plate 73 by means of a longitudinal piston bracket 154. One end of a longitudinal guide rail 146 is vertically fixed to the lower plate 72 by means of a rib. The longitudinal guide rail 146 is set parallel to the vertical plate on both sides of the longitudinal piston pump 151. An upper plate 74 is set parallel to the lower plate 72. The other end of the longitudinal guide rail 146 is fixedly connected to the upper plate 74 by means of a rib. The upper plate 74 and the vertical plate 73 are also fixed by means of a rib.

[0057] The longitudinal slider 1461 is slidably mounted on the longitudinal guide rail 146. The longitudinal slider 1461 is fixedly connected to the slider plate 145. The piston rod 153 penetrates the first protrusion 1531 and is fixedly connected. One side of the first protrusion 1531 is fixedly connected to the longitudinal slider 1461. At this time, the longitudinal water wave energy can be used to drive the longitudinal water pump unit 15 to operate normally through the transmission component 14.

[0058] The horizontal plate 75 is vertically fixed on the base plate 3, and the horizontal plate 75 is parallel to the horizontal guide rail 7. The horizontal piston pump 161 is fixed on the horizontal plate 75 near the horizontal guide rail 7 through the horizontal piston bracket 164. The piston rod 163 penetrates the second protrusion 1631 and is fixedly connected. One side of the second protrusion 1631 is fixedly connected to the longitudinal guide rail 146. At this time, the horizontal water wave energy can be used to make the horizontal water pump unit 16 operate normally through the transmission component 14.

[0059] Through the transmission assembly 14, the water wave energy collected by the float 11, connecting rod 12, and first universal joint mechanism 13 is converted into the movement of the first piston 1511 along the longitudinal guide rail 146 and the movement of the second piston 1611 along the transverse guide rail 7. This allows the omnidirectional water wave energy harvesting and power generation device to simultaneously collect transverse and longitudinal water wave energy, improving the collection efficiency of the collecting end 1 and thus increasing the working efficiency of the omnidirectional water wave energy harvesting and power generation device. The second universal joint mechanism 144 in the transmission assembly 14 makes the transmission of power more flexible, reducing hard contact and wear between parts, thereby increasing the service life of the omnidirectional water wave energy harvesting and power generation device.

[0060] Optionally, the transmission assembly 14 further includes a circular block frame 147, with the second universal joint mechanism 144 fixedly connected to one end of the circular block frame 147, and the other end of the circular block frame 147 rotatably connected to the slider plate 145. For example, the left universal joint 1443 is fixedly connected to one end of the circular block frame 147, and the other end of the circular block frame 147 is rotatably connected to the slider plate 145. The left universal joint 1443 forms a rotating pair with the slider plate 145 through the circular block frame 147, which can improve the degree of freedom, making the movement more flexible. Furthermore, during movement, it reduces the hard collision between the second universal joint mechanism 144 and the slider plate 145, extending the service life of the equipment.

[0061] Optionally, the float 11 is an X-shaped cross float. For example, the X-shaped cross float is divided into four parts through the intersection point, and the bottom surface of each part is an arc-shaped structure, which increases the contact area between the float 11 and the water surface, thereby enabling the float 11 to more sensitively sense water wave energy, increasing the water wave energy collection efficiency of the collection end 1, and thus improving the working efficiency of the omnidirectional water wave energy harvesting and power generation device.

[0062] Optionally, the base plate 3 has a rectangular surface, and four floats 4 are provided at the four corners of the bottom of the base plate 3. For example, the four floats 4 at the four corners of the bottom of the base plate 3 can make the entire omnidirectional water wave energy harvesting and power generation device float on the water surface, reducing the erosion of the omnidirectional water wave energy harvesting and power generation device by the water body and increasing the service life of the omnidirectional water wave energy harvesting and power generation device.

[0063] Optionally, there are four collecting ends 1, arranged in an array on the base plate 3. For example, the collecting ends 1 are arranged in a rectangular array on the base plate 3 with different orientations. When the collecting ends 1 are subjected to water wave energy along the direction of the connecting rod 12, a single collecting end 1 cannot collect the energy. At this time, the collecting ends 1 on adjacent sides can collect the water wave energy in this direction. With four collecting ends 1 with different orientations on the base plate 3, water wave energy generated in various directions can be collected, improving the collection efficiency of the collecting ends 1 for water wave energy, thereby improving the working efficiency of the omnidirectional water wave energy harvesting and power generation device.

[0064] Optionally, a housing 5 is provided on the base plate 3. The housing 5 has holes for the connecting rod 12 and the float 11 to extend out. The housing 5 covers the outside of the collecting end 1 and the generating end 2. For example, by providing a housing 5 on the base plate 3, when the water wave energy is large, it can prevent water from splashing onto the omnidirectional water wave energy harvesting and power generation device over a large area, thereby reducing the erosion of the omnidirectional water wave energy harvesting and power generation device by water and increasing the service life of the omnidirectional water wave energy harvesting and power generation device.

[0065] This invention also provides an array generator set, including multiple such arrays. Figures 1 to 11The omnidirectional water wave energy harvesting and power generation device shown is interconnected. Exemplarily, the omnidirectional water wave energy harvesting and power generation system of the present invention can be stacked and combined. The base plates 3 of the omnidirectional water wave energy harvesting and power generation devices are connected by hinges, forming a long, serpentine power generation array according to the surrounding terrain. This increases the working efficiency of the omnidirectional water wave energy harvesting and power generation device and can provide power to equipment with higher energy consumption.
