Description

Technical Field

[0001] This invention relates to the field of gasoline generator technology, and more specifically to a generator set with optimized gasoline combustion. Background Technology

[0002] A gasoline generator is a device that converts the chemical energy of gasoline into mechanical energy, and then into electrical energy through a generator. It is mainly used to provide independent or backup power. The core functions of a gasoline generator include power supply and charging. It is based on an engine-driven rotor, and the belt connection makes the speed ratio of the rotor to the engine 1.7-3 times. The output power is generally below 30kW, which is suitable for mobile scenarios. When the engine is running above idle speed, it supplies power to all electrical equipment (except the starter) and charges the battery at the same time to ensure stable power.

[0003] Chinese patent CN115977797A discloses a gasoline generator set. The gasoline generator set adopts a series arrangement structure, with the output shaft of the gasoline engine connected in series with the motor rotor. The exhaust gas generated by the combustion of the gasoline engine is processed by a heat recovery treatment component to recover heat and treat the exhaust gas more thoroughly. The heat is used to preheat the gasoline, which can make the gasoline combustion more complete, more environmentally friendly and energy-saving, and convenient for use in cold weather. At the same time, the gasoline engine base is equipped with a telescopic shock-absorbing moving mechanism for easy movement of the gasoline generator set.

[0004] Chinese patent CN104595026B discloses a portable internal frame inverter gasoline generator set, including an engine and a generator fixed to one side of the engine. The key feature is the inclusion of an inner support frame as a supporting skeleton, within which both the engine and generator are fixed. The front, rear, left, right, and top of the inner support frame are respectively secured with screws to the engine front cover, engine rear cover, engine left side plate, engine right side plate, and fuel tank. The engine front cover has an electrical box for housing the inverter assembly, which is electrically connected to the generator. Compared to traditional box-type inverter gasoline generator sets, this invention offers more convenient and time-saving assembly and maintenance, effectively improving production and maintenance efficiency while reducing production and maintenance costs.

[0005] During the operation of gasoline generators, the lubricating oil is commonly contaminated by gasoline, forming a mixed oil mixture. This problem is particularly serious in large gasoline generators. First, gasoline generators use a spark-ignition internal combustion engine structure with a low compression ratio. The fuel injection or carburetor system may allow unburned gasoline to seep into the crankcase due to needle valve wear, float sticking, or seal failure. Second, when combustion is incomplete, some gasoline will enter the lubricating oil chamber in liquid form through the piston ring gap. When this gasoline mixes with the lubricating oil, it will significantly change the physicochemical properties of the lubricating oil, including reducing viscosity, damaging oil film strength, and diluting additives. This will cause serious degradation of the core functions of the lubricating oil, such as lubrication and friction reduction, auxiliary cooling, and sealing and leak prevention.

[0006] In existing technologies, lubricating oil filtration relies on filters. Standard filters mainly depend on paper or metal filter media to intercept solid impurities such as metal shavings and dust. Their physical filtration mechanism cannot separate gasoline components that are already miscible with the lubricating oil. Even with bypass filters, it is still difficult to effectively remove light hydrocarbons. The continued aggravation of oil mixing will cause multiple negative effects, including increased internal engine wear, increased mechanical friction energy consumption, and reduced gasoline utilization efficiency. At the same time, gasoline mixing will accelerate lubricating oil oxidation, generating gum and acidic substances, corroding metal parts and clogging oil passages, further shortening the lubricating oil replacement cycle and increasing maintenance costs.

[0007] Therefore, the present invention provides a gasoline combustion optimized generator set that can achieve efficient separation of gasoline and lubricating oil, thereby improving fuel utilization and reducing lubricating oil waste. Summary of the Invention

[0008] To address the shortcomings of existing filtration technologies in separating gasoline contaminants, which not only reduces the reliability of the lubrication system but also causes energy waste and reduced equipment lifespan, a gasoline combustion-optimized generator set has been designed.

[0009] The technical solution adopted by this invention to solve its technical problem is as follows: a generator set for optimized gasoline combustion, including a generator set assembly, a gasoline engine and a gasoline generator installed inside it. An extension shaft is fixed to the end of the gasoline generator rotor away from the gasoline engine, and a gear set is installed at the other end of the extension shaft. The bottom of the gear set is connected to a drive shaft via a speed-increasing transmission. A separation section is fixed to the outside of the drive shaft. A feed pipe is installed above the middle of the conical surface of the separation section. A drive wheel is engaged at the bottom of the separation section. A discharge section is connected to the bottom of the drive wheel via a differential transmission. The separation section uses the power of the rotation of the gasoline generator rotor to drive the separation section to rotate, causing the gasoline and lubricating oil to form a mixed oil mixture to rotate. The two are separated by the difference in density of the two, and the increased fluidity of the mixed oil mixture after heating due to centrifugal force is used to separate the two. At the same time, the discharge section uses differential speed to guide the separated lubricating oil located at the edge of the separation section to be quickly removed from the separation section.

[0010] Furthermore, the gear set includes two vertically meshing bevel gears. One bevel gear is fixed to the end of the extension shaft away from the gasoline engine, and the inner side of the other bevel gear is fixed with a speed increaser via a connecting component. The output end of the speed increaser is fixed to the top of the drive shaft. The two bevel gear sets transmit the rotational force of the gasoline generator rotor to the speed increaser perpendicular to the rotor. The speed increaser increases the rotational speed and then transmits it to the drive shaft.

[0011] Furthermore, a drainage groove is provided at the top edge of the separator to guide the lubricating oil to slide out in a spiral. A flow divider is fixed on the inner side of the separator, and a discharge hole is provided through the bottom of the separator. An active tooth is fixed at the bottom edge of the flow divider.

[0012] Furthermore, a support plate is rotatably connected to the inner side of the drive gear, and the transmission wheel is rotatably connected to the top of the support plate, with the drive gear meshing with the top of the transmission wheel.

[0013] Furthermore, a cover plate is fixed to the top of the support plate, the feed pipe is fixed to the inside of the cover plate, a support ring is rotatably connected to the inside of the cover plate, the discharge part is fixed to the inside of the support ring, the support ring is set in a vortex shape, the support ring is used to guide lubricating oil, and a driven tooth is fixed to the bottom of the support ring. The driven tooth meshes with the bottom end of the transmission wheel. The transmission wheel, together with the driving tooth and the driven tooth, uses the different tooth ratios of the three to reduce the rotation speed of the support ring and the discharge part, so that the rotation speed of the discharge part is lower than the rotation speed of the separation part.

[0014] Furthermore, a base plate is fixed to the bottom of the support plate, and the inner side of the base plate is fixed to the oil box through a connecting component. The oil box is rotatably connected to the bottom of the separation part. An oil pipe is fixed to the bottom of the oil box, and the other end of the oil pipe is located on the outer side of the base plate. The base plate is fixed to the inner side of the unit assembly.

[0015] Furthermore, the flow divider is configured as a vortex line, with its direction consistent with the rotation direction of the separator. The side closer to the central axis of the separator is a flow-blocking section. The flow divider uses its protruding shape to block the oil-mixed mixture and prolong its movement time at the top of the separator. The side of the flow divider away from the central axis of the separator is a flow-guiding section. The groove of the flow-guiding section can provide a channel for gasoline to converge.

[0016] Furthermore, a discharge hole is provided through the outer side of the support ring, the support ring and the support plate are rotatably connected, the top of the support plate is provided with an inclined surface, the bottom of the support plate is fixed with a lubrication pipe, the other end of the lubrication pipe is located on the outer side of the bottom plate, and the lowest end of the inclined surface is located above the connection between the support plate and the lubrication pipe.

[0017] Furthermore, a bracket is fixed to the top of the speed increaser, and the extension shaft and the input end of the speed increaser are rotatably connected to the adjacent sides of the bracket, with the gear set located inside the bracket. The bracket is fixed inside the unit assembly, and a fuel tank is fixed to the top of the gasoline engine.

[0018] The beneficial effects of this invention are:

[0019] (1) The gasoline combustion optimized generator set of the present invention has a gasoline generator rotor that drives a vertically meshing gear set through an extended shaft, converting the horizontal rotational force into vertical power and transmitting it to the speed increaser. The speed increaser increases the input speed and drives the separation section to rotate at high speed through the drive shaft, directly utilizing the original kinetic energy of the generator without the need for additional energy input. Since the viscosity of the lubricating oil decreases significantly when the temperature rises to 70-90°C, the centrifugal force generated by the rotation speed of the separation section and the density difference work together to accelerate the stratification. The vortex design of the flow divider extends the movement path of the oil mixture on the cone surface, increasing the separation time and improving the lubricating oil and gasoline recovery rate, directly reducing the fuel replenishment frequency, and further reducing the total power consumption of the system by 10% through the internal circulation of kinetic energy.

[0020] (2) In the gasoline combustion optimized generator set of the present invention, the lubricating oil is heated to 70-90°C after flowing through high-temperature areas such as piston rings and cylinder liners. The increase in temperature leads to a decrease in the viscosity of the lubricating oil. At 70°C, the viscosity of typical lubricating oil is 40-50% lower than that at room temperature, and the fluidity is significantly enhanced. The high-temperature oil mixture is injected into the middle of the cone surface of the separator through the feed pipe. Its low viscosity makes it easier to diffuse and stratify under the action of centrifugal force. The flow divider utilizes the enhanced fluidity at high temperature to extend the movement path of the mixture without increasing viscous resistance, so that the gasoline and lubricating oil are more fully separated. At the same time, the high temperature reduces the residue on the surface of the separator, avoids mechanical wear caused by scale buildup, and extends the lubricating oil replacement cycle.

[0021] (3) The gasoline combustion optimized generator set of the present invention has a vortex structure of the support ring to guide the lubricating oil to move in a directional manner to the discharge groove. The inclined surface design of the support plate uses gravity to assist the flow of gasoline. The active tooth at the bottom of the separation section drives the transmission wheel. The bottom end of the transmission wheel meshes with the driven tooth at the bottom of the support ring. The number of teeth of the active tooth is less than the number of teeth of the driven tooth. The tooth difference design makes the rotation speed of the support ring and the discharge section lower than that of the separation section. This differential speed forms relative motion and produces a "scraping effect". The lubricating oil that is stuck at the edge of the separation section is pushed by the centrifugal force and is quickly removed along the surface of the discharge section because the rotation speed of the discharge section is low. The differential speed design also reduces the frictional heat at the edge of the separation section and avoids the carbonization of the lubricating oil caused by local overheating.

[0040] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example: Figures 1-16 As shown, the gasoline combustion optimized generator set of the present invention includes a generator set assembly and a gasoline engine 12 and a gasoline generator 13 disposed therein. A bracket 2 is fixed on the top of the speed increaser 3. An extension shaft 4 and the input end of the speed increaser 3 are respectively rotatably connected to the adjacent two sides of the bracket 2, and a gear set 5 is located inside the bracket 2. A fuel tank 11 is fixed on the top of the gasoline engine 12.

[0042] In this embodiment, the generator set includes a frame and generator components other than the gasoline engine 12, gasoline generator 13, and fuel tank 11. After the operator starts the gasoline engine 12, the intake valve of the gasoline engine 12 opens, the piston moves down, and the gasoline-air mixture is drawn into the cylinder. Then the intake / exhaust valve closes, the piston moves up to compress the mixture, and then the spark plug ignites the mixture. The explosion of the mixture pushes the piston down, realizing the conversion of thermal energy into mechanical energy. Finally, the exhaust valve opens, the piston moves up to discharge high-temperature exhaust gas. The gasoline generator 13 converts the piston kinetic energy into the power of crankshaft rotation, thereby driving the rotor to cut the stator magnetic field lines to generate alternating current. The alternating current is output after being rectified and regulated by an AVR. This is prior art and will not be described in detail here.

[0043] Specifically, an extension shaft 4 is fixed to one end of the gasoline generator 13 rotor away from the gasoline engine 12. A gear set 5 is provided at the other end of the extension shaft 4. The bottom of the gear set 5 is connected to a drive shaft 6 via a speed-increasing transmission. A separation section 7 is fixed to the outside of the drive shaft 6. A feed pipe 10 is provided above the middle of the conical surface of the separation section 7. A transmission wheel 9 is engaged at the bottom of the separation section 7. A discharge section 8 is connected to the bottom of the transmission wheel 9 via a differential transmission. The separation section 7 is driven to rotate by the rotation of the gasoline generator 13 rotor, which causes the gasoline and lubricating oil to form a mixed oil mixture. The two are separated by the increased fluidity of the mixture due to centrifugal force and the increased temperature of the mixture. At the same time, the discharge section 8 uses differential speed to guide the separated lubricating oil located at the edge of the separation section 7 to be quickly removed from the separation section 7.

[0044] In this embodiment, lubricating oil is drawn from the inside of the oil pan by an oil pump, filtered by a filter, and then moved to the vicinity of the piston rings / bearings to lubricate them. It is then removed from the inside of the gasoline engine 12. During this process, some gasoline mixes with the lubricating oil, creating a mixed oil mixture. As the lubricating oil flows through high-temperature areas such as the piston rings and cylinder liners, its temperature typically rises to 70–90°C, reducing its viscosity. The mixed oil mixture moves through the feed pipe 10 to the midpoint of the cone surface of the separator 7. Under the action of the separator 7, the mixed oil mixture undergoes centrifugal motion on the cone surface. Due to the significant density difference between the gasoline and lubricating oil forming the mixed oil mixture (gasoline density 0.72–0.78 g / cm³, lubricating oil 0.85–0.95 g / cm³), the two separate more significantly under centrifugal force. The centrifugal force on the lubricating oil is greater than gravity, causing it to be thrown to the outer edge, while the gravity on the gasoline is greater than the centrifugal force, causing it to gather towards the center.

[0045] Specifically, the gear set 5 includes two vertically meshing bevel gears. One bevel gear is fixed to the end of the extension shaft 4 away from the gasoline engine 12, and the inner side of the other bevel gear is fixed with a speed increaser 3 through a connecting component. The output end of the speed increaser 3 is fixed to the top of the drive shaft 6. The two bevel gear sets 5 transmit the rotational force of the gasoline generator 13 rotor to the speed increaser 3 which is perpendicular to the rotor. The speed increaser 3 increases the speed and then transmits it to the drive shaft 6.

[0046] In this embodiment, when the gasoline generator 13 is working, the rotor drives the extension shaft 4 to rotate. The extension shaft 4 drives the input end of the speed increaser 3 to rotate through the gear set 5. The speed increaser 3 increases the input speed (the standard speed of the gasoline generator 13 is generally 3000 rpm) to the speed required by the separation section 7 (generally greater than or equal to 6000 rpm), and then drives the drive shaft 6 to rotate through its output end. The drive shaft 6 drives the separation section 7 to rotate. The separation section 7 drives the top end of the transmission wheel 9 to rotate through the drive tooth 74 at its bottom, so that the transmission wheel 9 drives the driven tooth 84 to rotate. The driven tooth 84 drives the support ring 81 to rotate. The support ring 81 drives the discharge section 8 to rotate. The number of teeth at the top and bottom ends of the driven wheel is the same, and the number of teeth of the drive tooth 74 is less than the number of teeth of the driven tooth 84. As a result, the speed of the support ring 81 and the discharge section 8 is lower than that of the separation section 7 by 200-300 rpm, forming a speed difference. The tooth difference design makes the speed of the support ring 81 and the discharge section 8 lower than that of the separation section 7. This speed difference forms relative motion and produces a "scratching effect".

[0047] Specifically, a support plate 16 is rotatably connected to the inner side of the drive gear 74, and a transmission wheel 9 is rotatably connected to the top of the support plate 16. The drive gear 74 meshes with the top of the transmission wheel 9. A base plate 18 is fixed to the bottom of the support plate 16. The inner side of the base plate 18 is fixed to the oil box 19 through a connecting component. The oil box 19 is rotatably connected to the bottom of the separator 7. An oil pipe 15 is fixed to the bottom of the oil box 19. The other end of the oil pipe 15 is located outside the base plate 18. The base plate 18 is fixed to the inner side of the unit assembly. The diverter bar 71 is set as a vortex line, and its direction is consistent with the rotation direction of the separator 7. The side closer to the central axis of the separator 7 is the flow-blocking part 711. The diverter bar uses its convex shape to block the oil-mixed mixture and prolong its movement time at the top of the separator 7. The side of the diverter bar 71 away from the central axis of the separator 7 is the flow-guiding part 712. The groove of the flow-guiding part 712 can provide a channel for gasoline to converge.

[0048] In this embodiment, during this process, due to the vortex design of the diverter bar 71, the oil-mixed mixture is blocked from being subjected to centrifugal force and gravity. At the same time, due to contact with the baffle 711, it is subjected to the force of the baffle 711 towards the central axis of the separator 7, which changes its movement direction and prolongs the movement path of the oil-mixed mixture on the cone surface of the separator 7. This prolongs the separation time of the oil-mixed mixture on the surface of the separator 7. When the gasoline inside the diverter bar 71 moves downward to the bottom of the cone, it will converge to the guide section 712 and finally flow out from the end near the drive shaft 6 or move towards the drive shaft 6 after flipping over the top of the diverter bar 71. Finally, it converges to the bottom of the separator 7 cone, enters the oil box 19 through the discharge hole 82, and then flows back to the oil tank 11 or the gasoline engine 12 injector through the oil pipe 15 for reuse, thereby improving the utilization rate of gasoline.

[0049] Specifically, a discharge hole 82 is provided through the outer side of the support ring 81. The support ring 81 and the support plate 16 are rotatably connected. The top of the support plate 16 is provided with an inclined surface. A sealed bearing can be added at the connection between the support plate 16 and the support ring 81, or separate lubricating oil can be used to lubricate the driving gear 74, driven gear 84, and driven wheel 9. A lubrication pipe 14 is fixed at the bottom of the support plate 16. The other end of the lubrication pipe 14 is located outside the bottom plate 18. The lowest end of the inclined surface is located above the connection between the support plate 16 and the lubrication pipe 14. The top of the support plate 16... A cover plate 17 is fixed, and a feed pipe 10 is fixed inside the cover plate 17. A support ring 81 is rotatably connected to the inside of the cover plate 17. The discharge part 8 is fixed inside the support ring 81. The support ring 81 is vortex-shaped and is used to guide lubricating oil. A driven tooth 84 is fixed at the bottom of the support ring 81. The driven tooth 84 meshes with the bottom end of the transmission wheel 9. The transmission wheel 9, together with the driving tooth 74 and the driven tooth 84, uses the different tooth ratios of the three to reduce the rotation speed of the support ring 81 and the discharge part 8, so that the rotation speed of the discharge part 8 is lower than that of the separation part 7.

[0050] In this embodiment, the lubricating oil continues to move along the baffle 711 toward the edge of the separator 7, or after passing over the top of the diverter bar 71, it continues to move toward the side closer to the edge of the separator 7. As the lubricating oil rises along the conical surface, the centrifugal force it experiences weakens. At the same time, under the action of the lubricating oil that has not yet moved out from the edge of the separator 7, some lubricating oil is retained. At this time, since the rotation speed of the discharge section 8 is slightly lower than that of the separator 7, the retained lubricating oil is pushed by the subsequently separated lubricating oil and under the action of centrifugal force, it quickly passes over the edge of the separator 7 along the surface of the discharge section 8 and the drain groove 73 and enters the inner side of the support ring 81. Then, it flows into the top of the support plate 16 through the inner side of the support ring 81. Under the guidance of the inclined surface of the support plate 16, it enters the oil pan through the lubrication pipe 14 for reuse, thus completing the separation of gasoline and lubricating oil.

[0051] Specifically, bracket 2 is fixed inside the unit assembly.

[0052] In this embodiment, the bracket 2 is fixed to the inside of the frame, and the base plate 18 is fixed to the inside of the frame.

[0053] Working principle: Initial state as follows Figure 1-16As shown, before using this device, the operator first connects the lubrication pipe 14 to the oil return port of the oil pan, then connects the oil pipe 15 to the oil return port of the oil tank 11 or the oil injector of the gasoline engine 12, and connects the feed pipe 10 to the lubricating oil outlet of the gasoline engine 12. The operator starts the gasoline engine 12 to realize the conversion of thermal energy into mechanical energy. The gasoline generator 13 converts the piston kinetic energy into the power of crankshaft rotation, thereby driving the rotor to cut the stator magnetic field lines to generate alternating current. The alternating current is output after being rectified and regulated by an AVR. The lubricating oil is pumped from the oil pan. The mixture is pulled out from the side, filtered by the filter, and then moved to the vicinity of the piston rings / bearings for lubrication. It is then moved out from inside the gasoline engine 12. When the gasoline generator 13 is working, the rotor drives the extension shaft 4 to rotate. The extension shaft 4, through the gear set 5, drives the input end of the speed increaser 3 to rotate. The speed increaser 3 increases the input speed and drives the drive shaft 6 to rotate. The drive shaft 6 drives the separator 7 to rotate, the separator 7 drives the support ring 81 to rotate, and the support ring 81 drives the discharge section 8 to rotate. The mixed oil mixture moves to the conical surface of the separator 7 after passing through the feed pipe 10. At the bifurcation point, the oil-fuel mixture undergoes centrifugal motion on the conical surface of the separator 7 under the action of the separator 7. The centrifugal force on the lubricating oil is greater than the gravity, causing it to be thrown to the outer edge, while the gravity on the gasoline is greater than the centrifugal force, causing it to gather towards the center. During this process, due to the vortex design of the diverter bar 71, the oil-fuel mixture is separated on the surface of the separator 7. The gasoline inside the diverter bar 71 will converge to the guide section 712 as it moves downward to the bottom of the cone, and finally flow out from the end near the drive shaft 6 or flip over from the top of the diverter bar 71 towards the direction near the drive shaft 6. The lubricating oil moves and eventually flows back to the oil tank 11 or the oil injector of the gasoline engine 12. The lubricating oil continues to move towards the edge of the separation section 7 along the baffle 711, or after turning over the top of the diverter bar 71, it continues to move towards the side closer to the edge of the separation section 7. The rotation speed of the discharge section 8 is slightly lower than that of the separation section 7. The retained lubricating oil quickly turns over the edge of the separation section 7 and enters the inner side of the support ring 81 under the push of the subsequently separated lubricating oil and the action of centrifugal force. Then, it flows into the top of the support plate 16 through the inner side of the support ring 81. Under the guidance of the inclined surface of the support plate 16, it enters the oil pan through the lubrication pipe 14.
