Description

Technical Field

[0001] The present invention relates to the field of energy, and in particular to a conversion device and a conversion method for realizing dynamic work by using static pressure. Background Art

[0002] An engine is a device that provides power to power-demanding equipment and is considered an energy conversion device. For example, a car engine converts the thermal energy of gasoline / diesel into mechanical energy by burning it in a sealed cylinder, expanding the gas and pushing the piston to produce work. Another example is thermal power generation, which uses the heat generated by combustible materials to heat water, converting it into high-temperature, high-pressure steam. The steam pressure then drives a steam engine, which in turn drives a generator to generate electricity, achieving energy conversion.

[0003] With the diversification of energy conversion devices, methods for converting gravity and pressure to improve energy efficiency have begun to attract widespread attention. In patent CN114567122A, the inventors provide a device for generating electricity using gravity. This device utilizes the fixed and constant directionality of gravity, enabling the ratchet wheel, connected to the driven inner wheel, to rotate under the action of gravity. The power generated by the output shaft of the gravity converter is then transmitted to a high-power generator for power generation, achieving the conversion of gravity into electrical energy.

[0004] To overcome the problem of gravity conversion devices only performing work in the vertical direction, the inventors in patents CN115765314A and CN115833472A utilize static pressure to enable the rotor, while being driven by the stator coils, to continuously apply extrusion force to the pressure transmission mechanism through a pushing mechanism, thereby generating additional work and increasing output power. The process of achieving static pressure dynamic work in a pressure conversion device requires the pressure transmission mechanism / method to have high conversion efficiency and high stability during the conversion process. Therefore, it is necessary to explore and improve existing pressure transmission methods. Summary of the Invention

[0005] One object of the present invention is to provide a conversion device that uses static pressure to achieve dynamic work. The conversion device uses a rotor and an output shaft whose central axes are not colinear to perform synchronous and non-concentric rotation. During the rotation process, the relative positions of the sleeve and piston of at least one group of pressure conversion units arranged between the rotor and the output shaft continue to change, so that the push rod hinged on the piston can push the output shaft to rotate, and convert the static pressure applied to the output shaft into dynamic work on the output shaft. This not only effectively improves the output power of the output shaft, but also simplifies the pressure conversion mechanism, and the pressure conversion process is more stable, safe and reliable.

[0006] The above-mentioned purpose is achieved through the following technical solutions:

[0007] A conversion device that uses static pressure to achieve dynamic work, including a rotor, an output shaft located in the rotor, and at least one pressure conversion group connected between the rotor and the output shaft, the output shaft and the rotor are not collinear, the output shaft includes a main journal, the main journal is provided with a first journal and a second journal, the first journal, the second journal, and the main journal are not collinear; the pressure conversion group includes two pressure conversion mechanisms, the pressure conversion mechanism includes a sleeve fixedly connected to the inner wall of the rotor, a first cavity is provided in the sleeve, a piston movable along the sleeve is provided in the first cavity, a connecting rod is hinged on the piston, and the connecting rods of the two pressure conversion mechanisms in the same pressure conversion group are hingedly connected to the first journal and the second journal of the output shaft respectively.

[0008] In this technical solution, similar to the pressure cycle power generation device in the prior art, the conversion device includes a rotor, and the output shaft provided within the rotor is used to connect to an external load, such as the rotor of a generator. The rotor and the output shaft are not collinear, so that a pressure potential energy difference is formed between the output shaft and the rotor. Driven by the traction motor, the rotor rotates, driving the output shaft to rotate, and the rotor and the output shaft produce synchronous but non-concentric rotation. Through the pressure conversion group between the rotor and the output shaft, the extrusion force applied by the rotor to the pressure conversion group is converted into a driving force of the pressure conversion group on the output shaft, thereby driving the output shaft to rotate.

[0009] The present technical solution is different from the prior art in the arrangement of the output shaft and the pressure conversion group, as well as the connection method of the output shaft and the pressure conversion group.

[0010] Specifically, the output shaft includes a main journal, on which are disposed a plurality of first and second journals. The main journal, first journal, and second journal can be connected alternately in sequence, or the main journals can be provided at both ends, with the first and second journals connected alternately in the middle. The central axis of the main journal is the central axis of the output shaft. The main journals at both ends of the output shaft can be mounted on a lifting mechanism via bearings to adjust the offset between the central axis of the output shaft and the central axis of the rotor, thereby adjusting the pressure applied to the output shaft by the inner wall of the rotor via the pressure conversion group. The central axes of the first journal, the second journal, and the main journal are not collinear, meaning that the first journal and the second journal are offset relative to the main journal.

[0011] A pressure conversion group corresponds to a first journal and a second journal. The pressure conversion group includes two pressure conversion mechanisms. The two pressure conversion mechanisms have the same structure, and the difference lies in the installation position of each sleeve on the inner wall of the rotor and the journal to which the connecting rod is hinged. The sleeve included in the pressure conversion mechanism is fixedly installed on the inner wall of the rotor. When the rotor rotates with the traction motor, the sleeve rotates synchronously. A first cavity is provided in the sleeve. The piston in the first cavity can move along the axial direction of the sleeve. Lubricating oil can be provided in the first cavity between the bottom surface of the sleeve and the bottom surface of the piston, or not. A connecting rod is hinged on the piston, and the connecting rod is hinged on the first journal or the second journal. Therefore, the connecting rod can be flipped at a certain angle relative to the piston or relative to the journal.

[0012] During operation, the sleeves of each pressure conversion mechanism rotate synchronously with the rotor. During one rotation cycle / revolution of the pressure conversion mechanism with the rotor, the central axis of the output shaft is offset from the central axis of the rotor. For example, vertically, the central axis of the output shaft is some distance below the central axis of the rotor. This causes the distance between the sleeve and the piston of the pressure conversion mechanism to gradually decrease as the sleeve rotates from the top of the rotor to the bottom of the rotor. When the sleeve reaches the bottom of the rotor, the distance between the piston and the sleeve is minimized, and the piston is at its lowest position within the sleeve. At this point, the distance between the piston and the first / second journal is D. When the connecting rod length L is set to be greater than D, the connecting rod will push the first / second journal to rotate a certain angle, allowing the pressure conversion mechanism to pass through the bottom of the rotor, thereby causing the output shaft to rotate a certain angle. Similarly, as the sleeve of the pressure conversion mechanism rotates from the bottom of the rotor to the top of the rotor, the distance between the sleeve and the piston gradually increases. When the sleeve reaches the top of the rotor, the piston reaches its highest position within the sleeve. By analogy, when the rotor rotates one circle, each pressure conversion mechanism pushes the output shaft to rotate a certain angle, realizing the cyclic dynamic work of static pressure in the form of relay.

[0013] In the present invention, the pressure conversion mechanism adopts a sleeve and piston method, so that the distance between the sleeve and the piston changes continuously during the rotation of the rotor. During the change process, the piston pushes the output shaft to rotate a certain angle through the connecting rod, so that the pressure potential energy difference formed between the output shaft and the rotor is converted into a rotational force that continuously pushes the output shaft, thereby increasing the output power of the output shaft. At the same time, compared with the existing gear structure, the energy conversion of the piston, sleeve, connecting rod, and crankshaft output shaft is more stable, and the processing and production of parts and the matching requirements of parts are lower, the structure is simpler, and the reliability is higher.

[0014] In the present invention, the two pressure conversion mechanisms in the same pressure conversion group can have multiple implementation methods. In principle, as long as the connecting rod can push the output shaft to rotate a certain angle when the piston is at the low position of the stroke or near the low position of the stroke, energy conversion can be achieved.

[0015] In some preferred embodiments, in order to improve the output efficiency, in the same pressure conversion group, when the piston of one pressure conversion mechanism approaches the low position of the stroke, the piston of another pressure conversion mechanism approaches the high position of the stroke, the central axis of the first shaft neck and the central axis of the main shaft neck constitute a first plane, and the central axis of the second shaft neck and the central axis of the main shaft neck constitute a second plane, and the first plane and the second plane are not coplanar.

[0016] In this technical solution, the angle between the connecting rods of the two pressure conversion mechanisms is close to 180°, so that when one pressure conversion mechanism moves from a high stroke position to a low stroke position, it can continuously push the output shaft to rotate a certain angle. When the pressure conversion mechanism moves from a low stroke position to a high stroke position, the other pressure conversion mechanism moves from a high stroke position to a low stroke position, thereby relaying and continuously pushing the output shaft to rotate, thereby increasing the output power.

[0017] To improve cycling stability, the angle between the connecting rods of the two pressure conversion mechanisms is not equal to 180°. Specifically, a certain angle exists between the first plane formed by the center axis of the first journal and the center axis of the main journal, and the second plane formed by the center axis of the second journal and the center axis of the main journal. This makes it easier for the connecting rod to push the output shaft to rotate when the stroke is low.

[0018] In the present invention, there can be one pressure conversion group or multiple groups. The multiple pressure conversion groups can be located in the same plane so that during the rotation process, multiple pressure conversion mechanisms are simultaneously in the low position of the stroke; the multiple pressure conversion groups can also be located in different planes so that at the same time, only one pressure conversion mechanism is simultaneously in the low position of the stroke.

[0019] In some preferred embodiments, at least two pressure conversion groups are provided within the rotor, with an angle between the planes on which any two pressure conversion groups lie. Preferably, the angle between the connecting rods of the two pressure conversion mechanisms within each pressure conversion group is approximately 180°, thereby further improving the stability of the cyclic dynamic work and increasing output power.

[0020] In a preferred embodiment of the present invention, lubricating oil is disposed within the first cavity. The lubricating oil within the first cavity lubricates the area between the piston and the inner wall of the sleeve, allowing the piston to move more smoothly within the sleeve. Furthermore, the lubricating oil acts as a pressure buffer, reducing impact between the piston and sleeve, thereby ensuring a smoother and more reliable energy conversion process.

[0021] Furthermore, lubricating oil can flow between two pressure conversion mechanisms in the same pressure conversion group. Specifically, a third oil passage is provided in the piston, communicating with the first cavity. The third oil passage is connected to a second oil passage in the connecting rod via a hose. The second oil passage is connected to the first oil passage via an oil hole. The first oil passage extends from the first journal and the connecting plate to the second journal.

[0022] In this technical solution, a third oil channel is provided in the piston, connected to the second oil channel in the connecting rod via a hose. During one rotation of the pressure conversion mechanism, the tilt angle between the piston and the connecting rod is small, so the hose can be used to connect the two oil channels. Using the hose, rather than the hinge point between the piston and the connecting rod, not only ensures a smooth oil flow, but also allows for a variety of hinged connections between the piston and the connecting rod.

[0023] During one rotation of the pressure conversion mechanism, the connecting rod and the first / second journals rotate at a large angle. Therefore, a retaining ring can be installed at the hinged end of the connecting rod, which fits over the journal. The retaining ring has a hollow structure inside, which can communicate with the second oil passage and serve as part of the second oil passage. Lubricating oil in the second oil passage flows into the hollow structure of the retaining ring and then enters the first oil passage through the oil hole in the journal.

[0024] The first oil passage is located in the first journal and the second journal. In some embodiments, for the first journal and the second journal connected by a connecting plate, the first oil passage needs to pass through the connecting plate to communicate with the interiors of the two journals.

[0025] Through the above arrangement, during the rotation of the pressure conversion group, the lubricating oil can flow back and forth in the two first cavities through the third oil channel, the hose, the second oil channel, and the first oil channel, which not only can achieve buffering and lubrication in the two first cavities, but also the total amount of lubricating oil in the two first cavities and each oil channel is always consistent, which is conducive to maintaining constant pressure in the two first cavities and further improving the stability of the operation of the conversion device.

[0026] Furthermore, a third cavity is provided in the third oil channel, the inner diameter of the third cavity is larger than the inner diameter of the third oil channel, and a magnet is provided on the inner wall of the third cavity. In this technical solution, the inner diameter of the third cavity is larger than the inner diameter of the third oil channel, so that the flow rate of the lubricating oil slows down when passing through the third cavity. The lubricating oil with a slowed flow rate will have more time to be magnetized by the magnet, forming magnetized lubricating oil. The particles of the magnetized lubricating oil repel each other with the same poles, and move in a directional manner under the action of the magnetic field, so that large particles become small particles, and at the same time, the arrangement of the lubricating oil molecules is changed, so that its density is reduced, and finally the particle size of the lubricating oil is reduced, the contact area is increased, and the lubricating effect of the lubricating oil is improved. Not only that, the magnet can adsorb impurities in the lubricating oil in the third cavity, play a role in filtering and cleaning the lubricating oil, and can effectively extend the service life of the lubricating oil and the device.

[0027] Furthermore, along the extension direction of the third oil channel, the inner diameter of the third cavity first gradually increases and then gradually decreases. In this technical solution, the inner diameter of the third cavity first increases, which can slow down the flow rate of the lubricating oil, increase the time it stays in the third cavity, and thus prolong the time the magnet acts on the lubricating oil. Then, the inner diameter of the third cavity decreases to accelerate the lubricating oil and ensure that it flows smoothly in the oil channel. In some preferred embodiments, the third cavity includes a first variable diameter section, a straight section, and a second variable diameter section connected in sequence, wherein the inner diameter of the first variable diameter section gradually increases, the inner diameter of the straight section remains unchanged, and the inner diameter of the second variable diameter section gradually decreases.

[0028] Furthermore, the system further includes a mounting frame, wherein a lifting device is disposed within the mounting frame. The output end of the lifting device is connected to a suspension plate for carrying the output shaft, and the suspension plate is driven by the lifting device to move in a vertical direction. The lifting device disposed within the mounting frame can be a linear motor, a lead screw, or a hydraulic cylinder, so as to enable vertical movement of the suspension plate. The suspension plate is directly or indirectly connected to a bearing for mounting the main journal of the output shaft, thereby enabling the lifting device to flexibly adjust the vertical height of the output shaft, change the offset distance between the central axis of the output shaft and the central axis of the rotor, and adjust the pressure potential energy difference between the rotor and the output shaft.

[0029] Furthermore, the invention further comprises a traction motor, which is in transmission connection with the rotor. The traction motor and the rotor can be in transmission connection with each other through components such as a transmission belt, a gear, and a drive shaft, so that the rotor rotates under the drive of the traction motor.

[0030] Another object of the present invention is to provide a conversion method based on any of the aforementioned conversion devices, so as to stably increase the rotational force of the output shaft during the synchronous and non-concentric rotation of the rotor and the output shaft.

[0031] Specifically, the conversion method includes the following steps:

[0032] The rotor and the output shaft rotate synchronously but not concentrically;

[0033] During the rotation, the sleeve of the pressure conversion mechanism in the pressure conversion group moves relative to the piston;

[0034] When the piston moves from a stroke high position to a stroke low position, it pushes the hinged first journal or the second journal to move, thereby driving the output shaft to rotate.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] 1. The pressure conversion mechanism of the present invention continuously changes the distance between the sleeve and the piston as the rotor rotates. The piston pushes the output shaft to rotate a certain angle through the connecting rod, so that the pressure potential energy difference between the output shaft and the rotor is converted into a rotational force that continuously pushes the output shaft, thereby increasing the output power of the output shaft. At the same time, the energy conversion of the piston, sleeve, connecting rod, and crankshaft output shaft is more stable, and the processing and matching requirements of the components are lower, the structure is more simplified, and the reliability is higher.

[0037] 2. In the present invention, the angle between the connecting rods of the two pressure conversion mechanisms is close to but not equal to 180°, so that when the stroke is low, the connecting rods can more easily push the output shaft to rotate;

[0038] 3. During the rotation of the pressure conversion group of the present invention, lubricating oil can flow back and forth between the two first cavities through the third oil passage, the hose, the second oil passage, and the first oil passage. This not only achieves buffering and lubrication within the two first cavities, but also ensures that the total amount of lubricating oil in the two first cavities and each oil passage remains consistent, which helps maintain constant pressure within the two first cavities and further improves the operational stability of the conversion device.

[0039] 4. The third cavity of the piston of the present invention can slow down the flow rate of the lubricating oil and use a magnet to magnetize the lubricating oil, thereby improving the lubricating effect of the lubricating oil. At the same time, the magnet can adsorb impurities in the lubricating oil in the third cavity, thereby filtering and cleaning the lubricating oil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0051] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0052] Example 1:

[0053] like Figure 1 and Figure 2A conversion device for achieving dynamic work using static pressure is shown, comprising a rotor 6, an output shaft 4 located inside the rotor 6, and at least one pressure conversion group connected between the rotor 6 and the output shaft 4, wherein the output shaft 4 is not collinear with the rotor 6, and the output shaft 4 comprises a main journal 41, on which a first journal 42 and a second journal 43 are provided, and the first journal 42, the second journal 43, and the main journal 41 are not collinear; the pressure conversion group comprises two pressure conversion mechanisms, each comprising a sleeve 71 fixedly connected to the inner wall of the rotor 6, wherein a first cavity 73 is provided inside the sleeve 71, wherein a piston 72 movable along the sleeve 71 is provided inside the first cavity 73, and a connecting rod 8 is hingedly connected to the piston 72, and the connecting rods 8 of the two pressure conversion mechanisms in the same pressure conversion group are hingedly connected to the first journal 42 and the second journal 43 of the output shaft 4, respectively.

[0054] In some preferred embodiments, Figure 1 and 5 As shown, within the same pressure conversion group, when the piston 72 of one pressure conversion mechanism approaches the low stroke position, the piston 72 of the other pressure conversion mechanism approaches the high stroke position. The central axis of the first journal 42 and the central axis of the main journal 41 form a first plane, and the central axis of the second journal 43 and the central axis of the main journal 41 form a second plane. The first and second planes are not coplanar. In one or more embodiments, both pressure conversion mechanisms within the same pressure conversion group may approach the low stroke position or the high stroke position simultaneously.

[0055] In some preferred embodiments, Figure 5 As shown, at least two pressure conversion groups are included, and there is an angle between the planes where any two pressure conversion groups are located. In one or more embodiments, there can be multiple pressure conversion groups. Preferably, the conversion device is provided with 3 to 4 pressure conversion groups.

[0056] In one or more embodiments, Figure 1 As shown, it also includes a mounting frame 1, in which a lifting device 2 is provided. The output end of the lifting device 2 is connected to a suspension plate 3 for carrying an output shaft 4, and the suspension plate 3 moves in a vertical direction under the drive of the lifting device 2.

[0057] In one or more embodiments, the rotor can be driven to rotate by the traction motor of the conversion device or by an external traction motor. In some preferred embodiments, a traction motor 10 is further included, which is in transmission connection with the rotor 6.

[0058] When working, Figure 5As shown in FIG, the sleeves of each pressure conversion mechanism rotate synchronously with the rotor. In one cycle of the pressure conversion mechanism rotating with the rotor, since the center axis of the output shaft is lower than the center axis of the rotor by a certain distance, the sleeve of the pressure conversion mechanism rotates from the top of the rotor to the bottom of the rotor. Figure 6 As shown in (a)-(d), the distance between the sleeve and the piston gradually decreases. When the sleeve rotates to the bottom of the rotor, the distance between the piston and the sleeve is the smallest, and the piston is at the low position in the sleeve. At this time, the connecting rod pushes the first / second journal to rotate a certain angle so that the pressure conversion mechanism can pass through the bottom of the rotor, thereby causing the output shaft to rotate a certain angle. Similarly, as Figure 6 As shown in (e)-(h), when the sleeve of the pressure conversion mechanism rotates from the bottom of the rotor to the top of the rotor, the distance between the sleeve and the piston will gradually increase. When the sleeve rotates to the top of the rotor, the piston reaches the highest stroke position in the sleeve.

[0059] By analogy, when the rotor rotates one circle, each pressure conversion mechanism pushes the output shaft to rotate a certain angle, realizing the cyclic dynamic work of static pressure in the form of relay.

[0060] Example 2:

[0061] Based on Example 1, lubricating oil 11 is provided in the first cavity 73. The lubricating oil in the first cavity lubricates the area between the piston and the inner wall of the sleeve, allowing the piston to move more smoothly within the sleeve. The lubricating oil also acts as a pressure buffer, reducing impact between the piston and sleeve, making the energy conversion process smoother and more reliable.

[0062] In some preferred embodiments, Figure 3 As shown, a third oil passage 74 is provided within the piston 72, communicating with the first cavity 73. The third oil passage 74 is connected to a second oil passage 81 within the connecting rod 8 via a hose 77. The second oil passage 81 is connected to the first oil passage 45 via an oil hole 46. The first oil passage 45 extends from the first journal 42 and the connecting plate 44 to the second journal 43. During rotation of the pressure conversion group, lubricating oil can flow back and forth between the two first cavities via the third oil passage, the hose, the second oil passage, and the first oil passage. This not only provides buffering and lubrication within the two first cavities, but also ensures that the total amount of lubricating oil in the two first cavities and in each oil passage remains consistent, facilitating constant pressure within the two first cavities and further improving the operational stability of the conversion device.

[0063] In some preferred embodiments, a third cavity 78 is provided in the third oil passage 74 . The inner diameter of the third cavity 78 is larger than the inner diameter of the third oil passage 74 . A magnet 75 is provided on the inner wall of the third cavity 78 .

[0064] In some preferred embodiments, along the extension direction of the third oil passage 74, the inner diameter of the third cavity 78 first gradually increases and then gradually decreases. Figure 4 As shown, the third cavity 78 includes a first variable diameter section 781, a straight section 782 and a second variable diameter section 783, wherein the inner diameter of the first variable diameter section gradually increases, the inner diameter of the straight section remains unchanged, and the inner diameter of the second variable diameter section gradually decreases, and the magnet is arranged in the straight section to construct a magnetic field.

[0065] Example 3:

[0066] like Figure 7 A conversion method for realizing dynamic work by using static pressure is shown, which uses the conversion device in any of the above embodiments. The conversion method includes the following steps:

[0067] The rotor and the output shaft rotate synchronously but not concentrically;

[0068] During the rotation, the sleeve of the pressure conversion mechanism in the pressure conversion group moves relative to the piston;

[0069] When the piston moves from a stroke high position to a stroke low position, it pushes the hinged first journal or the second journal to move, thereby driving the output shaft to rotate.

[0070] The terms "first," "second," and "third" used in the present invention (e.g., first journal, second journal, first oil passage, second oil passage, third oil passage, etc.) are used only to distinguish corresponding components for the sake of clarity of description and are not intended to limit any order or emphasize importance. Furthermore, the term "connected" used in the present invention, unless otherwise specified, may refer to a direct connection or an indirect connection via other components.

[0071] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
