Description

Technical Field

[0001] The present invention relates to the technical field of magnetic energy power equipment, and particularly relates to a permanent magnetic energy power output device. Background Art

[0002] Traditional power equipment such as internal combustion engines and steam turbines generally uses petrochemical energy sources (such as gasoline, diesel, coal) as the energy source, and converts chemical energy into mechanical energy through combustion or chemical reactions. However, due to using petrochemical energy sources as the energy source, there are problems such as serious environmental pollution, high costs, and non-renewability of petrochemical energy sources. Therefore, magnetic energy power equipment has emerged. The magnetic energy power equipment realizes the conversion from magnetic energy to kinetic energy through the magnetic force interaction between an electromagnet and a permanent magnet.

[0003] However, the existing magnetic energy power equipment can only utilize a single magnetic pole of the permanent magnet, with low magnetic energy utilization rate. And during the actual operation of the magnetic energy power equipment, due to factors such as the current thermal effect, hysteresis loss, and eddy current loss of the electromagnet, a large amount of heat will be generated inside the equipment, resulting in demagnetization of the permanent magnet and an increase in the resistance of the electromagnet, thereby reducing the magnetic energy conversion efficiency and even affecting the service life of the equipment. Therefore, the existing magnetic energy power equipment usually sets a temperature sensor inside the equipment to monitor the temperature inside the equipment in real time. When the collected temperature exceeds the preset threshold, a cooling fan is started to cool the equipment by air cooling. However, the temperature sensor needs to work continuously with power on, constantly collecting temperature data, causing additional power consumption and further reducing the overall energy efficiency of the magnetic energy power equipment.

[0037] Embodiment

[0038] As Figures 1 to 7 shown, an embodiment of the present invention provides a permanent magnet energy power output device, including a device housing 1, a piston 2, a crankshaft monitoring module, an SMA heat dissipation module, a power control module 3, two U-shaped permanent magnets 4, and two electromagnetic coils 5.

[0039] Among them, in order to improve the heat dissipation capacity of the magnetic energy power output device, the material of the device housing 1 is aluminum alloy.

[0040] The piston 2 is slidably disposed in the device housing 1, and an installation through groove 7 is provided in the piston 2.

[0041] Preferably, piston guide rails 37 are fixedly provided at both opposite ends in the device housing 1. The piston guide rails 37 are fixedly connected to the device housing 1 through fixing bolts. The two ends of the piston 2 are slidably connected to the two piston guide rails 37. It is worth mentioning that the connection mechanism includes a crank 6 and a connecting rod 38. The crank 6 is rotatably installed in the device housing 1, and the opposite ends of the connecting rod 38 are respectively rotatably connected to the crank 6 and the piston 2.

[0042] Further, a connection groove 40 is provided at one end of the piston 2 close to the crankshaft 6. A connection hole 41 is provided through the connection groove 40. The connecting rod 38 is inserted into the connection groove 40 and is rotatably connected to the piston 2 through a connection pin 39. The other end of the connecting rod 38 is rotatably connected to the crankshaft 6.

[0043] Among them, with Figure 1 as a reference benchmark, the two piston guide rails 37 are disposed at the upper and lower ends of the piston 2. The piston 2 slides left and right in the two piston guide rails 37. When the piston 2 slides left and right, the crankshaft 6 is driven to rotate through the connecting rod 38. The two ends of the crankshaft 6 penetrate through the device housing 1 and are rotatably connected to the device housing 1 through bearings.

[0044] The two U-shaped permanent magnets 4 are oppositely arranged at both ends inside the installation through groove 7, and the two U-shaped permanent magnets 4 have the same poles facing each other. Among them, taking Figure 1 as a reference, the two U-shaped permanent magnets 4 are arranged at the left and right ends inside the installation through groove 7, that is, at both ends in the sliding direction of the piston 2. The two U-shaped permanent magnets 4 have the same poles facing each other, that is, the S poles of the two U-shaped permanent magnets 4 are completely opposite to each other, and the N poles are completely opposite to each other. The U-shaped permanent magnets 4 are fixedly installed on the piston 2 through a cover plate and fixing bolts. The two electromagnetic coils 5 are fixedly installed inside the device housing 1 and are respectively located between the two pairs of opposite magnetic poles of the two U-shaped permanent magnets 4. The winding directions of the coils of the two electromagnetic coils 5 are opposite, and the electromagnetic coils 5 are electrically connected to the power control module 3.

[0045] In some preferred embodiments, an aluminum alloy fixing sleeve 26 is fixedly installed inside the device housing 1. The aluminum alloy fixing sleeve 26 penetrates through the installation through groove 7, and two coil installation through holes 27 are provided inside it. Each electromagnetic coil 5 is fixedly arranged inside one of the coil installation through holes 27. The electromagnetic coil 5 includes a non-magnetic insulating core, a first enameled copper wire 24, and a second enameled copper wire 25. The first enameled copper wire 24 and the second enameled copper wire 25 are wound side by side along the axis of the non-magnetic insulating core on the non-magnetic insulating core. The starting end of the first enameled copper wire 24 is connected to the ending end of the second enameled copper wire 25. The ending end of the first enameled copper wire 24 and the starting end of the second enameled copper wire 25 are both electrically connected to the power control module 3.

[0046] In some preferred embodiments, the central axis of each coil installation through hole 27 is collinear with the central axis of the end faces of the two opposite magnetic poles of the two U-shaped permanent magnets 4 respectively. That is, the central axis of the plane where the two S poles of the two U-shaped permanent magnets 4 are located is collinear with the central axis of one coil installation through hole 27, and the central axis of the plane where the two N poles of the two U-shaped permanent magnets 4 are located is collinear with the central axis of the other coil installation through hole 27. The central axis of the electromagnetic coil 5 is collinear with the central axis of the coil installation through hole 27. Taking Figure 1 as a reference, when the electromagnetic coil 5 is energized, one of the electromagnetic coils 5 generates a magnetic field pointing from left to right / from right to left, and the other electromagnetic coil 5 generates a magnetic field pointing from right to left / from left to right. That is, at the same moment, the magnetic field directions generated by the two electromagnetic coils 5 are opposite. The two electromagnetic coils 5 jointly drive the two U-shaped permanent magnets 4 to move left and right, thereby causing the piston 2 to slide left and right on the piston guide rail 37.

[0047] The crankshaft monitoring module is arranged in the device housing 1 and is used to monitor the rotational speed, top dead center, and bottom dead center of the crankshaft 6. The crankshaft monitoring module is electrically connected to the power control module 3. The crankshaft monitoring module includes a signal gear 29 and a Hall position sensor 30. The Hall position sensor 30 is installed in the device housing 1 and is located on one side of the signal gear 29. Among them, the signal gear 29 can be a "60-2" tooth structure. It should be noted that the present application does not specifically limit the specific number of teeth of the signal gear 29. Those skilled in the art can reasonably design the number of teeth of the signal gear 29 according to the accuracy requirements. The Hall position sensor 30 detects the tooth trigger pulse signal of the signal gear 29 and transmits it to the power control module 3 to complete the monitoring of the rotational speed, top dead center, and bottom dead center of the crankshaft 6. The two "missing teeth" respectively correspond to the top dead center and the bottom dead center. The Hall position sensor 30 and the signal gear 29 monitoring the rotational speed, top dead center, and bottom dead center of the crankshaft 6 are conventional technical means in the art, so the working principle thereof will not be elaborated herein.

[0048] The SMA conduction mechanism 8 is arranged beside one of the U-shaped permanent magnets 4 and is connected to the connecting wire 9. The SMA conduction mechanism 8 is used to absorb the heat in the device housing 1 to deform and control the on / off of the connecting wire 9.

[0049] In some preferred embodiments, the SMA conduction mechanism 8 includes an insulating switch base 11, a positive electrode 12, a negative electrode 13, a conduction rod 14, an insulating mounting bracket 15, a heat-conducting shielding column 16, an SMA spring 17, a shielding slider 18, an insulating block 19, and two wiring components. The positive electrode 12 and the negative electrode 13 are arranged at intervals on the insulating switch base 11. One end of the conduction rod 14 is rotatably connected to the positive electrode 12, and the other end is lapped with the negative electrode 13. The insulating mounting bracket 15 is connected to the insulating switch base 11. The heat-conducting shielding column 16 is fixedly connected to the insulating switch base 11, and an installation inner hole 20 is provided at one end thereof. The SMA spring 17 is arranged in the installation inner hole 20, one end of which is connected to the heat-conducting shielding column 16, and the other end is connected to the shielding slider 18. The shielding slider 18 is slidably connected to the installation inner hole 20, and the insulating block 19 is provided at the end away from the SMA spring 17. One end of the insulating block 19 away from the shielding slider 18 is slidably connected to the conduction rod 14. Both of the two wiring components are arranged on the insulating switch base 11, are respectively connected to the positive electrode 12 and the negative electrode 13, and are both connected to the connecting wire 9. The wiring component includes a wiring hole 21, a conductive connecting plate, a wire pressing hole 22, and a wire pressing bolt 23. The wiring hole 21 is provided on the side surface of the insulating switch base 11. The conductive connecting plate is arranged in the wiring hole 21 and is connected to the positive electrode 12 or the negative electrode 13. The wire pressing hole 22 is provided on the upper surface of the insulating switch base 11 and is communicated with the wiring hole 21. The wire pressing bolt 23 is threadedly connected to the wire pressing hole 22 and is used to press the connecting wire 9 inserted into the wiring hole 21 against the conductive connecting plate.

[0050] In some preferred embodiments, the material of the heat-conductive shielding column 16 and the shielding slider 18 can be copper, the material of the insulating switch seat 11 can be polyimide or polyetheretherketone, which is fixedly installed on the device housing 1 through a connecting bracket not shown in the figure, and the upper and lower sides of the insulating block 19 away from the shielding slider 18 are provided with sliding columns 42, and the end of the conducting rod 14 close to the insulating block 19 is provided with an embedded groove, and the upper and lower sides of the embedded groove are provided with slide grooves, the insulating block 19 is embedded in the embedded groove and slidably connected with the embedded groove, the sliding column 42 is slidably connected with the slide groove, and the insulating block 19 slides with the conducting rod 14 through the embedded groove, the sliding column 42 and the slide groove The sliding column 42 is embedded in the slide groove. The SMA spring 17 is a shape memory alloy spring that has been pre-thermomechanically trained to achieve two-way deformation. Its material can be a standard equiatomic ratio nickel-titanium alloy, or a shape memory alloy such as NiTiPd, NiTiHf, etc. The above shape memory alloys are all existing products and can be purchased on the market, so they are not described in detail. It should be noted that the austenite start temperature, austenite end temperature, martensite start temperature and martensite end temperature of the SMA spring 17 are trained based on the rated operating temperature range of the U-shaped permanent magnet 4. Those skilled in the art can train the SMA spring 17 according to the selected material of the U-shaped permanent magnet 4. For example, if the U-shaped permanent magnet The maximum working temperature of 4 is 100°C, the martensite end temperature of the SMA spring 17 can be set to 40°C, the martensite start temperature is 60°C, the austenite start temperature is 70°C, and the austenite end temperature is 90°C. The shape memory alloy thermomechanical training process is an existing conventional technical means and is not repeated here. The SMA conduction mechanism 8 is arranged next to the U-shaped permanent magnet 4 to be closer to the working environment temperature of the U-shaped permanent magnet 4 and improve the temperature feedback accuracy. The SMA spring 17 absorbs the ambient heat near the U-shaped permanent magnet 4 through the heat-conducting shielding column 16 and heats up to the austenite start temperature, begins to elongate, and pushes the shielding slider 18 to slide toward the opening of the mounting inner hole 20, and then passes through the insulating block 1 9 pushes the conduction rod 14 to overlap the negative electrode 13, so that the SMA conduction mechanism 8 and the connecting wire 9 are connected as a whole. At this time, the cooling fan 10 is started to cool the magnetic energy power output device and reduce the temperature of the working environment. When the working environment temperature drops to the martensite starting temperature of the SMA spring 17, the SMA spring 17 begins to contract, driving the shielding slider 18 to slide toward the installation inner hole 20, and then the conduction rod 14 is pulled back through the insulating block 19, so that the SMA conduction mechanism 8 is disconnected, and the cooling fan 10 is powered off and turned off. It should be noted that the SMA spring 17 is initially in a contracted state. At this time, the conduction rod 14 and the negative electrode 13 are not in contact.The SMA conduction mechanism 8 is in an off state; thus, Figure 6 Taking this as a reference benchmark, one of the wiring components is located on the left side of the positive electrode 12, and the other wiring component is located on the right side of the negative electrode 13. The conductive connecting plate located on the left side of the positive electrode 12 is connected to the positive electrode 12 to achieve conduction, and the conductive connecting plate located on the right side of the negative electrode 13 is connected to the negative electrode 13 to achieve conduction. It should be mentioned that by surrounding the SMA spring 17 with the heat-conducting shielding column 16 and the shielding slider 18, not only can the SMA spring 17 be quickly heat-conducted, but also the influence of the alternating magnetic field generated by the electromagnetic coil 5 on the SMA spring 17 can be reduced.

[0051] It should be noted that the power control module 3 at least includes an MCU, a power module, an H-bridge chip, and other optimization circuits. Those skilled in the art can make reasonable designs according to specific needs, and this application does not make any restrictions, so it will not be elaborated here. The Hall position sensor 30 can be connected to the GPIO pin of the MCU as a digital switch type Hall position sensor. This application does not specifically limit the specific connection method between the Hall position sensor 30 and the MCU. For those skilled in the art, according to the specific selection of the Hall position sensor 30, it can also be connected to the ADC port of the MCU and other connection methods. The power module is connected to the MCU to provide the working voltage for the MCU and accept the control of the MCU. The control method can be based on the PWM pulse width modulation method. The power module is connected to the H-bridge chip, the H-bridge chip is connected to the electromagnetic coil 5, and the MCU is connected to the H-bridge chip. This application does not limit the specific models of the power module, MCU, and H-bridge chip. Those skilled in the art can purchase appropriate models in the market according to design requirements as long as the corresponding functions can be achieved. For example, the MCU can be a microcontroller of the STM32 series, and the H-bridge chip can be L298N, DRV8833, etc. The power module only needs to provide the required DC voltage, multiple outputs, and be controllable by the MCU. The power module is used to provide the working voltages of 3.3V / 5V for the MCU and the H-bridge chip, and to energize the electromagnetic coil 5 through the H-bridge chip. For those skilled in the art, the corresponding connection circuit can be designed according to the specific selection of the power module, MCU, and H-bridge chip. And the focus of this application is not on the improvement of the connection circuits of each structure, so the specific connection circuits will not be elaborated here. The MCU is used to control the path of the H-bridge chip to achieve the change of the current direction of the electromagnetic coil 5. Controlling the H-bridge chip by the MCU is a conventional technical means in the art. For those skilled in the art, reasonable designs can be made according to the specific selection of the MCU and the H-bridge chip.

[0052] In some preferred embodiments, the heat-conducting shielding column 16 is horizontally connected to the insulating mounting bracket 15 parallel to the horizontal plane, so that the sliding direction of the insulating block 19 is perpendicular to the vertical direction. It is worth mentioning that the heat-conducting shielding column 16 is arranged in the horizontal direction rather than the vertical direction, which can avoid the influence of the self-gravity of the insulating block 19 and the shielding slider 18 on the elongation / shortening of the SMA spring 17.

[0053] In some preferred embodiments, a digital bidirectional ammeter 28 is connected in series between the electromagnetic coil 5 and the power supply control module 3. The digital bidirectional ammeter 28 is electrically connected to the power supply control module 3 and is used to collect the current magnitude of the electromagnetic coil 5 and transmit the collected current parameters to the power supply control module 3. Among them, the digital bidirectional ammeter 28 and the MCU of the power supply control module 3 are connected through RS485. Those skilled in the art can add an RS485 transceiver chip according to the specific model of the selected MCU. By setting the digital bidirectional ammeter 28, the current of the electromagnetic coil 5 is collected in real time. Combining the rotational speed of the crankshaft 6 collected by the Hall position sensor, when the magnetic energy of the U-shaped permanent magnet 4 fades due to aging and the rotational speed of the crankshaft 6 decreases, the MCU controls the power supply module to increase the output voltage to the electromagnetic coil 5 to obtain a larger current, thereby enhancing the magnetic field generated by the electromagnetic coil 5 and maintaining the rotational speed of the crankshaft 6.

[0054] In some preferred embodiments, a lubricating oil system is further included. The lubricating oil system includes an oil storage tank 31, an oil outlet pipe 32, an oil return pipe 33, an oil collecting tank 34, and an oil pump 35. The oil storage tank 31 is arranged outside the device housing 1. The inlet of the oil pump 35 is communicated with the oil storage tank 31, and its outlet is communicated with one end of the oil outlet pipe 32. A plurality of injection nozzles 43 are arranged at the other end of the oil outlet pipe 32. The oil collecting tank 34 is arranged at the bottom of the device housing 1 and is used to receive the lubricating oil sprayed by the plurality of injection nozzles 43. The oil collecting tank 34 is connected to the oil return pipe 33, and the other end of the oil return pipe 33 is connected to the oil storage tank 31. The oil pump 35 and the power supply control module 3 are electrically connected.

[0055] The oil pump 35 is externally connected to an AC power supply through a relay. The relay is connected to the MCU in the power control module 3.
