Description

Technical Field

[0001] This invention relates to the technical field of engines, and more particularly to a hydraulic-pneumatic interactive cycloidal acceleration environmentally friendly engine. Background Technology

[0002] A hydraulic-pneumatic engine is a reciprocating power device that utilizes both hydraulic and pneumatic pressure energy as a common power source. This type of engine drives the piston to reciprocate linearly within the cylinder by alternately or collaboratively utilizing the pressure difference between hydraulic and pneumatic pressure acting on it. A crank-connecting rod mechanism converts this linear motion into rotational motion, thereby outputting mechanical work. The core of a hydraulic-pneumatic engine lies in its energy output through the conversion of medium pressure energy, rather than relying on the combustion of fossil fuels, thus belonging to the field of clean energy power technology.

[0003] In related technologies, existing power devices mainly include: traditional internal combustion engines, which generate high-temperature and high-pressure gas by burning fuel in the cylinder to drive the piston to do work; pure pneumatic engines, which typically use compressed air or atmospheric pressure to drive the piston by forming a vacuum; and pure hydraulic engines, which rely on high-pressure liquid provided by an external hydraulic pump station to drive the piston or motor to rotate.

[0004] Existing technologies have the following shortcomings: Traditional internal combustion engines rely on fossil fuels, resulting in high energy consumption and exhaust pollution. Secondly, pure pneumatic engines are limited by the upper limit of gas pressure, resulting in low power density and difficulty in meeting high power requirements. Furthermore, although pure hydraulic engines can generate huge thrust, they require a continuous external hydraulic power source, have poor independent operation capabilities, and have many energy conversion links with low efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0044] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention: a hydraulic-pneumatic interactive rotary acceleration environmentally friendly engine.

[0045] like Figure 1 — Figure 6 As shown in the figure, an embodiment of the present invention provides a hydraulic-pneumatic interactive cycloidal acceleration environmentally friendly engine, comprising:

[0046] Body 1;

[0047] The power output assembly 2 is located inside the body 1 and includes a reverse crankshaft wheel 21 and a flywheel 22. The reverse crankshaft wheel 21 is composed of a large crankshaft 211 and a small crankshaft 212 connected in reverse, wherein the radius of the large crankshaft 211 is larger than the radius of the small crankshaft 212, and the flywheel 22 is installed at the output end of the reverse crankshaft wheel 21.

[0048] Hydraulic drive assembly 3, disposed within the machine body 1, includes:

[0049] A high-force hydraulic cylinder 31 is located inside the machine body 1;

[0050] The force-bearing piston 32 is slidably sealed inside the high-force hydraulic cylinder 31, and the force-bearing piston 32 divides the interior of the high-force hydraulic cylinder 31 into an upper chamber and a lower chamber.

[0051] Small force-applying hydraulic cylinder 33 is located inside the machine body 1;

[0052] The force-applying piston 34 has a sliding seal inside the small force-applying hydraulic cylinder 33, and the inner diameter of the large force-applying hydraulic cylinder 31 is larger than the inner diameter of the small force-applying hydraulic cylinder 33.

[0053] Energy storage device 35 is located on one side of the body 1;

[0054] The first connecting rod 36 is rotatably connected at one end to the force-receiving piston 32 and at the other end to the large crankshaft 211;

[0055] The second connecting rod 37 is rotatably connected at one end to the force-applying piston 34 and at the other end to the small crankshaft 212.

[0056] It should be noted that the main body 1 is the supporting base of the entire engine, providing the mounting foundation and positioning for each component, ensuring motion accuracy and structural stability.

[0057] The power output assembly 2 is installed inside the machine body 1. Its function is to convert the reciprocating linear motion generated by the hydraulic drive assembly 3 into rotational motion and output mechanical energy externally, including:

[0058] The reverse crankshaft wheel 21 is formed by a large crankshaft 211 and a small crankshaft 212 fixedly connected in opposite directions. The radius of the large crankshaft 211 is larger than the radius of the small crankshaft 212. This reverse connection structure ensures that the two cranks always maintain a 180-degree phase difference during rotation, thereby realizing the alternating motion of the two pistons.

[0059] The large crankshaft 211 is connected to the force-receiving piston 32 through the first connecting rod 36, converting the up-and-down reciprocating motion of the force-receiving piston 32 into rotational motion;

[0060] The small crankshaft 212 is connected to the force-applying piston 34 through the second connecting rod 37, converting the reciprocating motion of the force-applying piston 34 into rotational motion, and at the same time using its small radius to control the stroke of the force-applying piston 34.

[0061] The flywheel 22 is installed at the output end of the counter-rotating crankshaft 21. It uses its rotational inertia to store and release rotational kinetic energy, making the engine output smoother and overcoming the dead point of piston movement.

[0062] The hydraulic drive assembly 3 is located inside the machine body 1 and is used to generate and transmit hydraulic pressure, which, together with atmospheric pressure, drives the engine to work.

[0063] The high-pressure hydraulic cylinder 31 is located inside the machine body 1. It has a large inner diameter and houses the pressure piston 32. It is the main place for atmospheric pressure work and hydraulic work. The upper part of the high-pressure hydraulic cylinder 31 is provided with a vent 55, which is connected to the atmosphere. When the pressure piston 32 moves downward, it is used to connect the chamber above the pressure piston 32 with the outside atmosphere, so as to ensure that the atmospheric pressure can be fully applied to the upper end face of the pressure piston 32.

[0064] The force-bearing piston 32 is slidably sealed inside the high-force hydraulic cylinder 31, dividing the interior of the high-force hydraulic cylinder 31 into an upper chamber and a lower chamber. The force-bearing piston 32 reciprocates along the cylinder body under the alternating action of atmospheric pressure difference and hydraulic force, and transmits power to the large crankshaft 211 through the first connecting rod 36.

[0065] The small-force hydraulic cylinder 33 is located inside the machine body 1. Its inner diameter is much smaller than that of the large-force hydraulic cylinder 31. It houses the force-applying piston 34, which is used to control the flow and pressure of hydraulic oil.

[0066] The force-applying piston 34 is slidably sealed inside the small force-applying hydraulic cylinder 33 and reciprocates under the drive of the small crankshaft 212. The hydraulic oil in and out of the lower chamber of the large force-applying hydraulic cylinder 31 is controlled by the hydraulic pipeline 38. The small driving force is amplified into a huge hydraulic pressure by utilizing the principle of area difference and applied to the force-applying piston 32.

[0067] The energy storage device 35 is installed on one side of the machine body 1 to store high-pressure hydraulic oil and to quickly release high-pressure oil into the lower chamber of the high-force hydraulic cylinder 31 during the hydraulic acceleration power stroke, providing instantaneous high-flow hydraulic energy.

[0068] One end of the first connecting rod 36 is rotatably connected to the force-bearing piston 32, and the other end is rotatably connected to the large crankshaft 211, transmitting the linear motion of the force-bearing piston 32 to the large crankshaft 211.

[0069] One end of the second connecting rod 37 is rotatably connected to the force-applying piston 34, and the other end is rotatably connected to the small crankshaft 212, transmitting the rotational motion of the small crankshaft 212 to the force-applying piston 34, driving it to reciprocate.

[0070] Specifically, firstly, the drain valve 4 located at the bottom of the high-pressure hydraulic cylinder 31 is opened, and the liquid in the lower chamber of the high-pressure hydraulic cylinder 31 is discharged, creating a low-pressure zone in the chamber. At the same time, due to the presence of the vent 55, the upper chamber above the force-bearing piston 32 is connected to the atmosphere. The upper surface of the force-bearing piston 32 is subjected to standard atmospheric pressure, creating a huge pressure difference between the upper and lower sides, which drives the force-bearing piston 32 to move downward. Through the first connecting rod 36, the large crankshaft 211 is driven to rotate downward, completing the atmospheric pressure power stroke. Simultaneously, the large crankshaft 211 drives the small crankshaft 212 to rotate upward in the opposite direction through the reverse connection. The small crankshaft 212 drives the force-applying piston 34 to move upward through the second connecting rod 37, and the lower chamber of the small force-applying hydraulic cylinder 33 is filled with hydraulic oil.

[0071] When the force-bearing piston 32 reaches the bottom dead center, the first control valve 39 and the second control valve 310 open simultaneously. The high-pressure oil stored in the accumulator 35 enters the large-force hydraulic cylinder 31 through the second control valve 310, causing the force-bearing piston 32 to move upwards. This causes the large crankshaft 211 to rotate upwards via the connecting rod, and the small crankshaft 212 to rotate downwards in the opposite direction via the reverse connection. The second connecting rod 37 forces the force-applying piston 34 to move downwards, pressurizing the hydraulic oil in the lower chamber of the small force-applying hydraulic cylinder 33. This pressurizes the hydraulic oil in the lower chamber of the large-force hydraulic cylinder 31 through the hydraulic line 38, acting upwards on the force-bearing piston 32. According to Pascal's principle, a small force applied to the small force-applying piston 34 will generate a huge thrust on the large-force-bearing piston 32, pushing the force-bearing piston 32 to move upwards rapidly. This continues to drive the large crankshaft 211 to rotate upwards via the first connecting rod 36, completing the hydraulic acceleration power stroke.

[0072] In one embodiment of the present invention, the hydraulic drive assembly 3 further includes:

[0073] Hydraulic line 38 connects the lower chamber of the small force-applying hydraulic cylinder 33 to the lower chamber of the large force-receiving hydraulic cylinder 31;

[0074] The first control valve 39 is installed on the hydraulic line 38;

[0075] The second control valve 310 is installed on the pipeline between the outlet of the accumulator 35 and the lower chamber of the high-force hydraulic cylinder 31.

[0076] It should be noted that the hydraulic line 38 is used to connect the lower chamber of the small-force hydraulic cylinder 33 and the lower chamber of the large-force hydraulic cylinder 31, forming a hydraulic oil flow channel so that the two hydraulic cylinders can achieve hydraulic interaction.

[0077] The first control valve 39 is installed on the hydraulic line 38 and is used to control the opening and closing of the hydraulic line 38 between the small force hydraulic cylinder 33 and the large force hydraulic cylinder 31. When needed, the valve is opened so that the hydraulic oil in the lower chamber of the small force hydraulic cylinder 33 can flow into the lower chamber of the large force hydraulic cylinder 31, thereby realizing the transmission and amplification of hydraulic force.

[0078] The second control valve 310 is installed on the pipeline between the outlet of the accumulator 35 and the lower chamber of the high-pressure hydraulic cylinder 31, and is used to control the timing and flow rate of the release of high-pressure oil in the accumulator 35. It opens at the beginning of the hydraulic acceleration power stroke, allowing the high-pressure oil stored in the accumulator 35 to quickly enter the lower chamber of the high-pressure hydraulic cylinder 31, pushing the force-bearing piston 32 upward.

[0079] Specifically, during the atmospheric pressure power stroke, the second control valve 310 is closed, and the accumulator 35 does not participate in the operation. When the force-bearing piston 32 moves to the bottom dead center, the first control valve 39 and the second control valve 310 open. The high-pressure oil in the accumulator 35 enters the lower chamber of the large-force hydraulic cylinder 31 through the second control valve 310. At the same time, the high-pressure oil also enters the lower chamber of the small-force hydraulic cylinder 33 through the hydraulic line 38 and the first control valve 39. Since the inner diameter of the small-force hydraulic cylinder 33 is much smaller than that of the large-force hydraulic cylinder 31, according to Pascal's principle, the small force formed on the small-force piston 34 can generate a huge thrust on the large-force piston 32, pushing the force-bearing piston 32 to move rapidly upward, completing the hydraulic acceleration power stroke. Through the coordinated control of the first control valve 39 and the second control valve 310, the precise release of hydraulic energy and the efficient amplification of hydraulic force are achieved.

[0080] In one embodiment of the present invention, a drain valve 4 is connected to the lower chamber of the high-force hydraulic cylinder 31, and the drain valve 4 is located at the bottom of the high-force hydraulic cylinder 31.

[0081] It should be noted that the drain valve 4 is connected to the bottom lower chamber of the high-pressure hydraulic cylinder 31 and is used to control the discharge of liquid in the lower chamber. When the drain valve 4 is opened, the liquid in the lower chamber below the force piston 32 is discharged, creating a low-pressure area or even a vacuum state in the chamber. When the drain valve 4 is closed, the lower chamber remains sealed, preparing for subsequent hydraulic work.

[0082] In one embodiment of the present invention, an auxiliary power supply system is further included, the auxiliary power supply system comprising:

[0083] Electric motor 51;

[0084] The first hydraulic pump 52 has its input end connected to the output end of the motor 51, and its outlet is connected to the inlet of the accumulator 35.

[0085] Battery pack 53 is electrically connected to motor 51;

[0086] Generator 54 is connected to flywheel 22 via a transmission, and the output terminal of generator 54 is electrically connected to battery pack 53.

[0087] It should be noted that the auxiliary power supply system provides energy support for the start-up and continuous operation of this engine, ensuring that the system can work independently and stably.

[0088] The electric motor 51 serves as the starting power source, and its output end is connected to the first hydraulic pump 52 for driving the first hydraulic pump 52 when the engine starts. The electrical energy required by the electric motor 51 is provided by the battery pack 53.

[0089] The input end of the first hydraulic pump 52 is driven by the electric motor 51, and its outlet is connected to the inlet of the energy storage device 35. When the electric motor 51 starts, the first hydraulic pump 52 operates, pressurizes the low-pressure hydraulic oil, and delivers it to the energy storage device 35 for storage, thus reserving energy for the subsequent hydraulic acceleration power stroke.

[0090] Battery pack 53 is electrically connected to motor 51, providing starting power to motor 51. Battery pack 53 is rechargeable and serves as an independent power source during engine startup.

[0091] The generator 54 is connected to the flywheel 22 via a transmission, and its output is electrically connected to the battery pack 53. When the engine enters a stable operating state, the flywheel 22 continues to rotate, driving the generator 54 to generate electricity. The generated electrical energy is then sent to the battery pack 53 for recharging, thus recovering and utilizing the energy.

[0092] Specifically, before the engine starts, the battery pack 53 supplies power to the electric motor 51, which drives the first hydraulic pump 52 to charge the energy storage device 35 with high-pressure oil, storing energy for the first hydraulic work. After the engine starts and enters the stable operation stage, the rotational kinetic energy of the flywheel 22 is converted into electrical energy by the generator 54, continuously charging the battery pack 53. The electrical energy stored in the battery pack 53 can be used for the next start or to supplement the driving force of the electric motor 51.

[0093] In one embodiment of the present invention, a high-flow-rate gear hydraulic pump 6 is further included, which is connected to the flywheel 22 via a drive, and the outlet of the high-flow-rate gear hydraulic pump 6 is connected to the inlet of the accumulator 35.

[0094] It should be noted that the high-flow gear hydraulic pump 6 is connected to the flywheel 22, and its outlet is connected to the inlet of the accumulator 35, which is used to continuously replenish high-pressure hydraulic oil to the accumulator 35 during engine operation.

[0095] In one embodiment of the present invention, an electric vacuum pump 7 is further included for evacuating the lower chamber of the high-force hydraulic cylinder 31. The electric vacuum pump 7 is connected to the lower chamber of the high-force hydraulic cylinder 31 to further enhance the driving force of the atmospheric pressure power stroke.

[0096] It should be noted that the electric vacuum pump 7 is an electrically driven gas extraction device that can quickly extract residual air or liquid from the lower chamber, creating a low-pressure state within the chamber that is closer to absolute vacuum. This device is powered by an external power source or battery pack 53 and can be independently controlled to start and stop.

[0097] When this device is in use, the first step is to prepare for startup: the battery pack 53 supplies power to the motor 51, the motor 51 drives the first hydraulic pump 52 to operate, pressurize the low-pressure hydraulic oil and deliver it to the energy storage device 35 for storage, so as to reserve energy for the first hydraulic work.

[0098] At the start-up phase, the drain valve 4 located at the bottom of the high-pressure hydraulic cylinder 31 is opened, draining the liquid from the lower chamber of the high-pressure hydraulic cylinder 31 and creating a low-pressure zone within the chamber. Simultaneously, the electric vacuum pump 7 is activated, actively evacuating the lower chamber of the high-pressure hydraulic cylinder 31 to further remove residual air, creating a low-pressure state closer to absolute vacuum. At this time, due to the presence of the vent 55, the upper chamber above the force-bearing piston 32 is connected to the atmosphere. The upper surface of the force-bearing piston 32 is subjected to standard atmospheric pressure, creating a significant pressure difference between the upper and lower sides, driving the force-bearing piston 32 downwards.

[0099] The force-receiving piston 32 moves downward, driving the large crankshaft 211 to rotate via the first connecting rod 36, completing the atmospheric pressure power stroke. At the same time, the large crankshaft 211 drives the small crankshaft 212 to rotate synchronously in the opposite direction via the reverse connection. The small crankshaft 212 drives the force-applying piston 34 to move upward via the second connecting rod 37, pressing the hydraulic oil in the lower chamber of the small force-applying hydraulic cylinder 33 into the lower chamber of the large force-receiving hydraulic cylinder 31 through the hydraulic pipeline 38.

[0100] When the force-bearing piston 32 moves to the bottom dead center, the first control valve 39 and the second control valve 310 open simultaneously. The high-pressure oil stored in the accumulator 35 enters the lower chamber of the large-force hydraulic cylinder 31 through the second control valve 310. At the same time, the high-pressure oil also enters the lower chamber of the small-force hydraulic cylinder 33 through the hydraulic line 38 and the first control valve 39. Since the inner diameter of the small-force hydraulic cylinder 33 is much smaller than that of the large-force hydraulic cylinder 31, according to Pascal's principle, the small force formed on the small-force piston 34 generates a huge thrust on the large-force piston 32, pushing the force-bearing piston 32 to move upward rapidly. Through the first connecting rod 36, it continues to drive the large crankshaft 211 to rotate, completing the hydraulic acceleration power stroke.

[0101] The piston 32 reciprocates in this way, while the crankshaft 21 and flywheel 22 rotate continuously, outputting power outward. The flywheel 22 uses its rotational inertia to store and release rotational kinetic energy, making the engine output more stable and overcoming the dead point of the piston movement.

[0102] After the engine enters a stable operating state, the generator 54, which is driven by the flywheel 22, starts generating electricity. The generated electrical energy is sent to the battery pack 53 for recharging, realizing energy recovery and utilization. At the same time, the high-flow gear hydraulic pump 6, which is driven by the flywheel 22, works synchronously to continuously replenish the energy storage device 35 with high-pressure hydraulic oil, storing energy for the subsequent hydraulic acceleration power stroke. Through the coordinated control of the first control valve 39 and the second control valve 310, the hydraulic energy is precisely released and the hydraulic force is efficiently amplified. This cycle repeats continuously, and the engine continues to operate stably, constantly outputting power to the outside.

[0103] In summary, the hydraulic-pneumatic interactive rotary acceleration environmentally friendly engine of this invention achieves two-stroke power through the interaction of atmospheric pressure and hydraulic energy. During the atmospheric pressure power stroke, the piston moves downwards using the atmospheric pressure difference, and during the hydraulic acceleration power stroke, it moves upwards using hydraulic pressure. This allows for continuous operation without fuel combustion, solving the problems of traditional internal combustion engines that rely on fossil fuels, have high energy consumption, and cause severe exhaust pollution. The engine utilizes a conjoined, reverse-connected crankshaft wheel axle, consisting of a large crankshaft and a small crankshaft connected in opposite directions. This, along with the first and second connecting rods, drives the force-receiving piston and the force-applying piston respectively, achieving efficient conversion between the alternating reciprocating motion and rotational motion of the two pistons. The large crankshaft is connected to the force-receiving piston via the first connecting rod, converting the linear motion of the force-receiving piston into rotational motion; the small crankshaft is connected to the force-applying piston via the second connecting rod, converting the reciprocating motion of the force-applying piston into rotational motion. Simultaneously, the reverse connection structure ensures that the two cranks maintain a 180-degree phase difference during rotation, ensuring coordinated and orderly piston movement. The engine boasts a compact and reliable structure with high transmission efficiency.
