Description

Technical Field

[0001] This invention belongs to the field of wave power generation buoy technology, specifically relating to an array-type multi-point absorption power generation buoy and method that mimics the blood circulation of a bionic heart pump. Background Technology

[0002] With the continued growth of global energy demand and the increasing severity of environmental problems, developing clean and renewable ocean energy has become an important way to solve the energy crisis. Wave energy, due to its wide distribution, high energy density, and strong sustainability, is considered one of the most promising ocean energy sources.

[0003] Currently, the mainstream wave energy generation technologies are mainly divided into oscillating water column (OWC), oscillating floating body (OB), and overtaking (OT). Among them, the oscillating floating body technology directly absorbs wave energy through a floating body structure and uses mechanical transmission or hydraulic system to drive the generator. However, its mechanical parts are easily worn by wave impact, and the energy conversion efficiency fluctuates significantly under the action of random waves, resulting in insufficient power generation stability.

[0004] In recent years, biomimetic technology has been introduced into the field of wave energy, such as power generation devices that mimic the swimming motion of fish or the contraction of jellyfish, achieving energy capture through flexible structures. However, such biomimetic devices are mostly limited to single-unit designs, resulting in problems such as dispersed energy output and low collaborative efficiency, making it difficult to form a modular system.

[0017] Meanwhile, this invention also provides a biomimetic heart-pumping circulation array-type multi-point absorption power generation method, which uses the aforementioned biomimetic heart-pumping circulation array-type multi-point absorption power generation buoy, and includes the following steps:

[0018] S1. Wave data is collected in real time using a wave meter, and the flow rate at the inlet of the turbine generator is monitored in real time using a flow sensor.

[0019] S2. Based on the real-time collected wave condition data, calculate the average value of wave energy for multiple cycles; based on the maximum and minimum values ​​among the multiple average values, and in combination with the rated power of the hydro-generator, determine the upper and lower limits of the energy conversion of the hydro-generator under the current wave condition.

[0020] S3. Based on the upper and lower limits of energy conversion of the hydro-generator, determine the upper and lower limits of the liquid flow at the inlet of the hydro-generator through the flow sensor, and form the flow control range at the inlet of the hydro-generator.

[0021] S4. Use a flow control valve to control the liquid flow rate at the inlet of the hydro-generator. If the liquid flow rate at the inlet of the hydro-generator is within the flow control range, maintain the opening of the flow control valve; if the liquid flow rate at the inlet of the hydro-generator is greater than the flow control range, reduce the opening of the flow control valve and increase the load on the hydro-generator; if the liquid flow rate at the inlet of the hydro-generator is less than the flow control range, increase the opening of the flow control valve and reduce the load on the hydro-generator.

[0022] Preferably, in step S2, the specific method for determining the upper and lower limits of the energy conversion of the hydro-generator under the current wave condition is as follows: if the maximum value among multiple average values ​​exceeds the rated power of the hydro-generator, then the upper limit of the energy conversion of the hydro-generator under the current wave condition is based on the rated power of the hydro-generator, and the lower limit of the energy conversion is based on the minimum value among multiple average values; if the maximum value among multiple average values ​​does not exceed the rated power of the hydro-generator, then the upper limit of the energy conversion of the hydro-generator under the current wave condition is based on the maximum value among multiple average values, and the lower limit of the energy conversion is based on the minimum value among multiple average values.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The buoy of this invention draws on the principles of heart pump and blood circulation, converting blood circulation into liquid circulation inside the buoy, and converting the wave energy captured by the energy capture device into liquid potential energy in the power generation device. The liquid potential energy is then converted into mechanical energy and electrical energy by a water turbine generator, thus effectively utilizing wave energy.

[0025] The buoy of this invention uses an array of multiple energy capture devices arranged outside the mother buoy to absorb wave energy at multiple points, ensuring that the buoy can absorb energy from wave conditions at different frequencies, storing discrete wave energy collectively, and also ensuring that potential energy can be converted into stable fluid kinetic energy when released, thereby enabling the hydro-generator to generate electricity efficiently.

[0026] The method of the present invention controls the opening degree of the flow control valve and the load of the hydro-generator to match the speed of the hydro-generator with the current wave conditions, maintain a stable power generation state with high efficiency and high reliability, and improve the service life of the hydro-generator.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. To make the above features and advantages of this invention more apparent and understandable, specific embodiments are provided below with reference to the accompanying drawings for detailed description.

[0043] like Figures 1 to 8 As shown, an embodiment of the present invention provides a biomimetic heart-pumping blood circulation array-type multi-point absorption power generation buoy, including a mother float 1, a power generation device 2, and multiple (e.g., four) energy capture devices 3. The power generation device 2 is fixed inside the mother float 1. The power generation device 2 includes a potential energy collection chamber 21, a water turbine generator 22, and a liquid collection chamber 23. The bottom outlet of the potential energy collection chamber 21 is connected to the inlet of the water turbine generator 22. The inlet of the water turbine generator 22 is provided with a flow regulating valve 29 for controlling the liquid flow rate. The outlet of the water turbine generator 22 is connected to the top inlet of the liquid collection chamber 23. The side wall of the potential energy collection chamber 21 is provided with a liquid inlet pipe 24, and the side wall of the liquid collection chamber 23 is provided with a liquid outlet pipe 25.

[0044] Multiple energy capture devices 3 are arrayed outside the main float 1. Each energy capture device 3 includes a sub-float 31, a protective cover 32, and a retractable bladder 33. The protective cover 32 is fixed inside the sub-float 31, and the top of the retractable bladder 33 is fixed inside the protective cover 32. The top inlet of the sub-float 31 is connected to an inlet hose 51 that communicates with the retractable bladder 33. Multiple inlet hoses 51 are connected to outlet pipes 25. The top outlet of the sub-float 31 is connected to an outlet hose 52 that communicates with the retractable bladder 33. Multiple outlet hoses 52 are connected to inlet pipes 24. A push rod 37 is fixedly connected to the bottom of the retractable bladder 33, and the lower end of the push rod 37 slides through to the outside of the sub-float 31.

[0045] The buoy in this embodiment adopts a principle similar to the heart's pumping blood circulation, converting the blood circulation motion into a unidirectional circulation flow of fluid inside the buoy, and converting the wave energy obtained by the sub-buoy 31 into the fluid potential energy stored in the mother buoy 1. The specific working process is as follows: In the mother buoy 1, the liquid in the potential energy collection chamber 21 flows into the water turbine generator 22 through the flow regulating valve 29. The water turbine generator 22 first converts the liquid energy into mechanical energy, and then converts the mechanical energy into electrical energy. The liquid in the water turbine generator 22 flows into the liquid collection chamber 23. Outside the main float 1, multiple arrayed energy harvesting devices 3 pump liquid from the liquid collection chamber 23 to the potential energy collection chamber 21. Specifically, utilizing the wave crests and troughs, the sub-float 31 moves up and down with the waves, and relative vertical movement occurs between the sub-float 31 and the push rod 37. When the push rod 37 causes the retractable bladder 33 to extend downward, the liquid in the liquid collection chamber 23 flows into the retractable bladder 33 through the outlet pipe 25 and the inlet hose 51. When the push rod 37 causes the retractable bladder 33 to retract upward, the liquid in the retractable bladder 33 flows into the potential energy collection chamber 21 through the outlet hose 52 and the inlet pipe 24. This wave energy enables the liquid to circulate and transport, allowing the hydro-generator 22 to continuously generate electricity. The number of energy harvesting devices 3 can be adjusted according to the wave conditions.

[0046] In this embodiment, to balance the pressure within the potential energy collection chamber 21 and the liquid collection chamber 23, a gas pipe 28 connects the top of the potential energy collection chamber 21 to the top of the liquid collection chamber 23. To create a significant height difference between the potential energy collection chamber 21, the hydro-generator 22, and the liquid collection chamber 23, the bottom outlet of the potential energy collection chamber 21 is connected to the inlet of the hydro-generator 22 via a first liquid pipe 26, and the outlet of the hydro-generator 22 is connected to the top inlet of the liquid collection chamber 23 via a second liquid pipe 27. During operation, the liquid in the potential energy collection chamber 21 flows into the hydro-generator 22 through the first liquid pipe 26 and the flow regulating valve 29, and the liquid in the hydro-generator 22 flows into the liquid collection chamber 23 through the second liquid pipe 27. The liquid can be a non-corrosive liquid medium (such as water) to improve the buoy's lifespan.

[0047] In this embodiment, to facilitate pipe connection, multiple inlet hoses 51 are connected to the outlet pipe 25 via a first multi-port pipe 41. Each inlet hose 51 is equipped with an inlet check valve 53. For example, the outlet end of the inlet hose 51 is fixedly connected (e.g., threaded) to the inlet end of the inlet check valve 53. The outlet end of the inlet check valve 53 is fixedly connected to the sub-float 31 and leads to the retractable bladder 33. The inlet check valve 53 prevents backflow of liquid within the retractable bladder 33. Inside the inlet hose 51, multiple outlet hoses 52 are connected to the inlet pipe 24 via a second multi-port pipe 42. Each outlet hose 52 is equipped with an outlet check valve 54. For example, the inlet end of the outlet hose 52 is fixedly connected (e.g., threaded) to the outlet end of the outlet check valve 54. The inlet end of the outlet check valve 54 is fixedly connected to the sub-float 31 and leads to the retractable bladder 33. The outlet check valve 54 prevents liquid in the outlet hose 52 from flowing back into the retractable bladder 33. Each port of the first multi-port pipe 41 and the second multi-port pipe 42 can be provided with internal or external threads; any extra ports are sealed with plugs 43. To improve liquid circulation efficiency, the diameter of the outlet pipe 25 is larger than the diameter of the inlet hose 51, and the diameter of the inlet pipe 24 is larger than the diameter of the outlet hose 52.

[0048] In this embodiment, to limit the travel range of the retractable bladder 33, a pressure spring 36 is provided between the bottom of the retractable bladder 33 and the bottom of the protective cover 32. The pressure spring 36 ensures that the retractable bladder 33 can reciprocate within its travel range. To improve the sealing performance of the sub-buoy 31, a drive through hole 313 for the push rod 37 to pass through is provided at the center of the bottom of the sub-buoy 31. The drive through hole 313 (e.g., at its upper opening) is provided with a sealing ring 314 (such as a rubber ring) that slides and engages with the push rod 37. The sealing ring 314 can be fixed to the bottom of the sub-buoy 31 with bolts. The push rod 37 passes through the sealing ring 314 and slides and seals with the sealing ring 314.

[0049] In this embodiment, for ease of assembly and maintenance, the mother float 1 includes a first cavity 11 and a first end cap 12, the first end cap 12 being fixed (e.g., bolted) at the top opening of the first cavity 11; the daughter float 31 includes a second cavity 311 and a second end cap 312, the second end cap 312 being fixed (e.g., bolted) at the top opening of the second cavity 311; the protective cover 32 includes a cover body 321 and a sealing ring 322, the sealing ring 322 being fixed at the edge of the top opening of the cover body 321; the retractable bladder 33 has a flange 331 at the edge of the top opening, the flange 331 being fixed between the sealing ring 322 and the cover body 321; the second end cap 312, the sealing ring 322, and the cover body 321 are fixedly connected. The shape of the main float 1 is preferably, but not limited to, cylindrical. Its first cavity 11 is cylindrical, and its first end cap 12 is circular. The main float 1 can be suspended in seawater, with part of it above the water surface and part of it below the water surface. To improve the utilization rate of wave energy, the shape of the sub-float 31 is preferably, but not limited to, conical. The bottom center of the cover 321 has an opening for the push rod 37 to pass through.

[0050] In this embodiment, a fixing hole 332 for mounting a push rod 37 is provided at the center of the bottom of the retractable bladder 33. A first annular groove 333 surrounding the fixing hole 332 is provided on the upper surface of the bottom of the retractable bladder 33. A first sealing plate 34 is installed above the bottom of the retractable bladder 33. The center of the first sealing plate 34 is fixedly connected to the top of the push rod 37. A first protruding ring 341 that mates with the first annular groove 333 is provided on the lower surface of the first sealing plate 34. A second annular groove 334 surrounding the fixing hole 332 is provided on the lower surface of the bottom of the retractable bladder 33. A second sealing plate 35 is installed below the bottom of the retractable bladder 33. A second protruding ring 351 that mates with the second annular groove 334 is provided on the upper surface of the second sealing plate 35. The edges of the first sealing plate 34, the bottom of the retractable bladder 33, and the edges of the second sealing plate 35 are fixedly connected (e.g., by bolts and nuts).

[0051] In this embodiment, in order to locate the buoy's mother float 1 and energy capture device 3, a first mooring ring 111 is provided at the bottom of the mother float 1, and a second mooring ring 371 is provided at the bottom of the push rod 37. The first mooring ring 111 and the second mooring ring 371 are connected by one end of a rope, and the other end of the rope can be fixed to a fixed object such as the seabed or the shore, so that the buoy can be positioned in a specific sea area.

[0052] Meanwhile, this embodiment also provides an array-type multi-point absorption power generation method based on a biomimetic heart pumping circulation, which uses the aforementioned array-type multi-point absorption power generation buoy based on a biomimetic heart pumping circulation, and includes the following steps:

[0053] S1. Use a wave meter to collect wave condition data (i.e., water depth, wave height, and wave period data) in real time, and use a flow sensor to monitor the flow rate at the inlet of the turbine generator 22 in real time.

[0054] S2. Based on the real-time collected wave condition data, calculate the average value of wave energy for multiple cycles; based on the maximum and minimum values ​​among the multiple average values, and in conjunction with the rated power of the hydro-generator 22, determine the upper and lower limits of energy conversion of the hydro-generator 22 under the current wave condition.

[0055] S3. Based on the upper and lower limits of energy conversion of the hydro-generator 22, the upper and lower limits of liquid flow at the inlet of the hydro-generator 22 are determined by the flow sensor to form the flow control range at the inlet of the hydro-generator 22.

[0056] S4. The flow rate at the inlet of the hydro-generator 22 is controlled by the flow regulating valve 29. If the flow rate at the inlet of the hydro-generator 22 is within the flow control range, the opening of the flow regulating valve 29 is maintained. If the flow rate at the inlet of the hydro-generator 22 is greater than the flow control range, the opening of the flow regulating valve is reduced and the load on the hydro-generator 22 is increased. If the flow rate at the inlet of the hydro-generator 22 is less than the flow control range, the opening of the flow regulating valve is increased and the load on the hydro-generator 22 is reduced.

[0057] In this embodiment, the array-type multi-point absorption power generation method for biomimetic heart-pumping circulation may further include the following steps:

[0058] S5. Determine if the buoy is continuously generating electricity. If yes, return to step S2; otherwise, stop working.

[0059] In this embodiment, in step S1, the flow sensor (omitted in the figure) can be installed on the first liquid pipe 26 to monitor the flow rate of the liquid flowing into the first liquid pipe 26 in real time.

[0060] In this embodiment, in step S2, taking the collection of wave data for 20 cycles (each cycle 4-5s) as an example, the average value of wave energy for each cycle can be calculated to obtain twenty average values; the average value of wave energy for every two consecutive cycles can be calculated to obtain ten average values; or the average value of wave energy for every four consecutive cycles can be calculated to obtain five average values.

[0061] In this embodiment, the specific method for determining the upper and lower limits of energy conversion of the hydro-generator 22 under the current wave condition in step S2 is as follows: if the maximum value among multiple average values ​​exceeds the rated power of the hydro-generator 22, then the upper limit of energy conversion of the hydro-generator 22 under the current wave condition is based on the rated power of the hydro-generator 22, and the lower limit of energy conversion is based on the minimum value among multiple average values; if the maximum value among multiple average values ​​does not exceed the rated power of the hydro-generator 22, then the upper limit of energy conversion of the hydro-generator 22 under the current wave condition is based on the maximum value among multiple average values, and the lower limit of energy conversion is based on the minimum value among multiple average values.

[0062] In this embodiment, in step S3, the upper limit of liquid flow at the inlet of the hydro-generator 22 is determined by the flow sensor based on the upper limit of energy conversion of the hydro-generator 22; the lower limit of liquid flow at the inlet of the hydro-generator 22 is determined by the flow sensor based on the lower limit of energy conversion of the hydro-generator 22; and the flow control range at the inlet of the hydro-generator 22 is determined by the upper limit and lower limit of liquid flow at the inlet of the hydro-generator 22.

[0063] In this embodiment, step S4 controls the opening of the flow control valve and the load on the turbine generator 22 (i.e., the resistance applied to the turbine generator 22) to match the current wave conditions, so that the speed of the turbine generator 22 is not too fast or too slow, thereby improving the service life of the turbine generator 22.

[0064] In this embodiment, step S5 can determine whether the buoy is continuously generating electricity at predetermined intervals (such as one hour), which enables the hydro-generator 22 to work efficiently under different wave conditions and avoids damage.

[0065] In this embodiment, the wave meter, flow sensor, and flow regulating valve 29 are all existing products, and they are all electrically connected to the control device. The control device can be a PLC, microcontroller, etc., and the specific model is not limited. In this embodiment, both the mother float 1 and the daughter float 31 adopt existing sealing technology.
