Description

Technical Field

[0001] The invention relates to the technical field of generators, and in particular to a kinetic energy storage magnetic levitation permanent magnet generator with a spring escapement mechanism. Background Art

[0002] In rural areas of my country and other countries, especially developing countries, as well as in other harsh conditions such as border defense units, field exploration, and wilderness survival, the lack of electricity often leads to nighttime lighting and communications becoming a huge obstacle. Therefore, the development of micro-small, low-cost electricity is an important way to solve the contradiction between the vast rural environment and resources, and is of great significance to promoting rural informatization and lighting in my country and other countries, especially developing countries, and to rural sustainable development and progress.

[0003] Batteries and power banks can solve the problem of short-term power shortages, but batteries are expensive and only last when they are used up; power banks need to be recharged after the power is used up, and the purchase and charging of batteries are restricted under difficult conditions. Photovoltaic, wind power, hydropower and other projects have been developed both at home and abroad, but the cost is high and it is difficult to carry. In addition, new energy resources such as solar, wind, and hydropower are extremely unstable, and the electricity generated by these resources generally needs to be stored, such as rechargeable batteries and pumped storage. However, pumped storage is expensive; battery charging and energy storage efficiency is extremely low, and rechargeable batteries also have a certain number of charging times and life, and they are not always available.

[0004] Patent 201710011983.2 provides a spring-spring micro-generator that converts manpower into micro-electricity using a knob switch, spring spring, multi-stage gears, bearings, ratchets, pawls, USB interfaces, micro-generators, damping gears and damping plates. However, the deceleration effect of the damping gears and damping plates will greatly consume the input energy of manpower, making the output power duration unsatisfactory. In addition, the performance of each device, especially the spring spring, will change with the influence of seasonal temperature thermal expansion and contraction and other factors. In particular, the wear of the damping gear and the damping plate will cause the restoring force of the spring to be unbalanced with the subsequent friction force. This unbalanced force may be extremely small, but it will seriously affect the power generation capacity, stability, and power duration. If the friction force is slightly greater than the restoring force of the spring, the connected micro-generator is likely to not rotate or generate electricity; otherwise, the micro-generator will appear to be flying, resulting in a short-term and high-density release of the spring energy storage, threatening the safety of the generator and various connected components.

[0005] Patent 200910028774.4 provides a spring-powered environmentally friendly flashlight; it uses a handle, a torsion spring, a micro-generator, a gearbox, a handle brake device, an anti-backlash device, etc. to convert manpower into micro-electricity for lighting. However, this solution, like Patent 201710011983.2, cannot evenly distribute kinetic energy to the micro-generator on time. During the release of the handle brake device, either the recovery coefficient of the torsion spring is slightly larger, resulting in a short-term and rapid release of spring energy in large quantities, which may lead to a dangerous situation where the micro-generator flies away, or the recovery coefficient of the torsion spring is slightly smaller, and the spring cannot drive the motor to rotate and generate electricity; and because the moving parts of this patent are directly coupled and connected, the capture stage lasts for a long time, during which the micro-generator may not rotate or generate electricity, and the output power fluctuates greatly.

[0006] Therefore, it is necessary to develop a low-cost, safe and stable micro-power generation device that can be used in practice. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Example: See Figures 1 to 5 A kinetic energy storage magnetic levitation permanent magnet generator with a spring escapement mechanism comprises a housing, a spring energy storage unit, a escapement unit, a speed increasing coupling unit and a magnetic levitation power generation unit.

[0032] The spring energy storage unit comprises an input shaft 1, a ratchet 2 and a check wheel 3. One end of the input shaft 1 extends into the housing and is fixedly connected to the ratchet 2, and the input shaft 1 can drive the ratchet 2 to rotate synchronously; in specific implementation, the input shaft 1 is connected to the housing through a bearing to ensure the stability of the input shaft 1; the output shaft is connected to a crank 35 at one end outside the housing, and the input shaft 1 can be driven to rotate through the crank 35, so that the input shaft 1 is driven to rotate through the crank 35 to input mechanical energy (kinetic energy). In specific use, the crank 35 can be driven to rotate in one direction by manpower or other low-speed and high-torque forces. The ratchet 2 has several pawls distributed around it, and the pawls have the same inclination direction. The check wheel 3 is located on one side of the ratchet 2 and is rotatably connected to the housing through a support shaft 4. The side close to the ratchet 2 has a check pawl 5, and the inclination direction of the check pawl 5 is opposite to the inclination direction of the pawl on the side of the ratchet 2 close to the check wheel 3, and extends between two adjacent pawls. The side of the check wheel 3 facing away from the ratchet wheel 2 is provided with a pawl 6, and the inclination direction of the pawl 6 is the same as the inclination direction of the check pawl 5; a check block 7 is provided on the side of the inclination direction of the pawl 6, and a spring seat 8 is provided on the side of the pawl 6 facing away from the inclination direction, and a check spring 9 is provided between the spring seat 8 and the pawl 6, and the two ends of the check spring 9 are respectively connected to the spring seat 8 and the pawl 6, and under the action of the check spring 9, the pawl 6 and the check block 7 are tightly together. By setting the check wheel 3, the ratchet 2 can only rotate in one direction, that is, during the forward rotation of the ratchet 2, the pawl on the ratchet 2 is squeezed by the check pawl 5 on the check wheel 3, which can drive the pawl 6 to compress the spring, so that the check wheel 3 rotates until the pawl is separated from the check pawl 5, and the check wheel 3 is reset; when the ratchet 2 rotates in the reverse direction, since the pawl 6 is in close contact with the check block 7 and is limited by the check block 7, the pawl on the ratchet 2 is squeezed by the check pawl 5 on the check wheel 3 and cannot rotate, thereby realizing the unidirectional rotation of the input shaft 1 and the ratchet 2, that is, the unidirectional input of mechanical energy (kinetic energy).

[0033] The spring energy storage unit includes a power spring sheet 10 and a primary driving gear 11, and the primary driving gear 11 is rotatably connected to the housing through a primary gear shaft; the primary gear shaft coincides with the axis of the input shaft 1, and there is a spacing (or gap) between the end of the primary gear shaft close to the input shaft 1 and the input shaft 1; when assembled, the end of the primary gear shaft away from the input shaft 1 is connected to the housing through a bearing. The primary driving gear 11 is installed on the primary gear shaft and can rotate synchronously with the primary gear shaft. The power spring sheet 10 is located between the primary driving gear 11 and the ratchet 2, and is wound around the primary gear shaft, and its inner end is fixedly connected to the primary gear shaft. A spring connecting column 13 is provided on the side of the ratchet 2 close to the primary driving gear 11, and the outer end of the power spring sheet 10 is fixedly connected to the spring connecting column 13. In this way, when the ratchet 2 rotates, it can drive the power spring sheet 10 to rotate around the primary gear shaft. Since the power spring sheet 10 is fixedly connected to the gear shaft 12, the input mechanical energy (kinetic energy) can be stored during the rotation of the power spring sheet 10.

[0034] The longitudinal escapement unit includes a longitudinal escapement mechanism, a longitudinal escapement driving gear 14 and a longitudinal escapement driven gear 15. The longitudinal escapement driving gear 14 and the longitudinal escapement driven gear 15 are rotatably connected to the housing through a longitudinal escapement gear shaft 16, the axis of which is parallel to the axis of the input shaft 1, and the longitudinal escapement driving gear 14 and the longitudinal escapement driven gear 15 can both rotate synchronously with the longitudinal escapement gear shaft 16. The longitudinal escapement driving gear 14 is meshed with the primary driving gear 11, and the longitudinal escapement driven gear 15 is located on the side of the longitudinal escapement driving gear 14 away from the ratchet 2. Near the edge of the side of the longitudinal escapement driven gear 15 away from the longitudinal escapement driving gear 14, there are several longitudinal escapement posts 17 evenly distributed around it, and the longitudinal escapement posts 17 are perpendicular to the longitudinal escapement driven gear 15 and are located on a circle concentric with the longitudinal escapement driven gear 15. The longitudinal escapement mechanism includes a longitudinal escapement handle 18, a rotating shaft 19, and a longitudinal escapement hairspring 20; the longitudinal escapement handle 18 is located on the side of the longitudinal escapement driven gear 15 away from the longitudinal escapement driving gear 14, one end of which is connected to the housing through the rotating shaft 19, and the other end has two arms, so that the longitudinal escapement handle 18 is Y-shaped as a whole; wherein the length of one arm is greater than the length of the other arm, and the end of one arm is located outside the circle where the longitudinal escapement column 17 is located, and the end of the other arm is located inside the circle where the longitudinal escapement column 17 is located. In the actual processing process, the longitudinal escapement handle 18 is located between the primary gear shaft and the longitudinal escapement gear shaft 16, and its extension line is tangent to the circle where the longitudinal escapement column 17 is located; this makes it easier for the longitudinal escapement mechanism to restrict the longitudinal escapement column 17. The long arm extends to the middle of the longitudinal escapement driven gear 15, and the long arm bulges away from the longitudinal escapement driven gear 15 corresponding to the position of the longitudinal escapement column 17, forming a clearance groove for the longitudinal escapement column 17 to pass through; thereby avoiding interference between the arm and the longitudinal escapement column 17, and ensuring the normal operation of the entire generator. A longitudinal catch 21 is connected to the end of each arm, one end of the longitudinal catch 21 is connected to the arm, and the other end extends in opposite directions and extends to between two adjacent longitudinal catches 17 to form a misalignment; wherein, the spacing between the two longitudinal catches is half of the spacing between two adjacent longitudinal catches 17, and when the longitudinal catch 17 pushes the longitudinal catch 21 on the short arm to move, the longitudinal catch handle 18 starts to swing, and after the longitudinal catch 18 swings to the maximum amplitude, it swings back, and at the same time, the longitudinal catch 17 continues to rotate, and when the longitudinal catch 18 returns to the initial position, the longitudinal catch 17 rotates to contact the inclined surface of the longitudinal catch 21 on the long arm, thereby pushing the longitudinal catch 21 to move, so that the longitudinal catch 18 swings in the opposite direction; when the longitudinal catch 18 swings and returns to the initial position again, the rear longitudinal catch 17 rotates to contact the inclined surface of the longitudinal catch 21 on the short arm, thereby realizing a cyclic operation; in this way, the amplitude and frequency of the swing of the longitudinal catch 18 can be guaranteed to be consistent, thereby making the power generation stability better.The end of the longitudinal catch 21 away from the support arm is an inclined surface, and the inclined surface faces the direction of the rotating shaft 19. In the initial state (that is, when the power spring sheet 10 has no energy storage), the longitudinal catch 17 contacts the inclined surface of the longitudinal catch 21 on the short support arm or contacts the inclined surface of the longitudinal catch 21 on the long support arm, or the longitudinal catch 17 is inside the quadrilateral formed by the inclined surfaces of the two longitudinal catches 21 (to ensure that the longitudinal escapement mechanism can automatically start to vibrate); when the power spring sheet 10 drives the primary driving gear 11 to rotate, and the primary driving gear 11 drives the longitudinal escapement driven gear 15 to rotate via the longitudinal escapement driving gear 14, the longitudinal catch 17 squeezes the longitudinal catch 21. Since the contact surface between the longitudinal catch 17 and the longitudinal catch 21 is an inclined surface, the longitudinal catch 21 can be pushed to move through the longitudinal catch 17, thereby driving the longitudinal escapement handle 18 to swing, thereby achieving vibration. The longitudinal escapement hairspring 20 is wound around the rotating shaft 19, and its inner end is fixedly connected to the rotating shaft 19; when implemented, the longitudinal escapement hairspring 20 is a spring wire, through which the longitudinal escapement hairspring 20 can drive the longitudinal escapement arm and the longitudinal escapement to reciprocate around the axis of the rotating shaft 19 (the rotation center line of the hairspring). A fixed pile 22 is provided on one side of the rotating shaft 19, and the outer end of the longitudinal escapement hairspring 20 is fixedly connected to the fixed pile 22; when the longitudinal escapement handle 18 rotates, it drives the rotating shaft 19 to rotate, and then, under the action of the longitudinal escapement hairspring 20, the rotating shaft 19 and the longitudinal escapement handle 18 can swing at a fixed frequency and amplitude, thereby slowly and orderly intermittently releasing mechanical energy (kinetic energy). The speed of mechanical energy (kinetic energy) release is determined by the length or distance between the longitudinal escapement handle 18 (rotating shaft 19) and the longitudinal escapement handle 18, the rotational inertia of the longitudinal escapement handle 18, the elastic coefficient of the longitudinal escapement hairspring, the circumferential distribution density of the longitudinal escapement column 17, and the friction therein. The greater the moment of inertia of the longitudinal escapement 18, the length of the longitudinal escapement 18, the friction force, the circumferential distribution density of the longitudinal escapement teeth, etc., the slower the energy release speed, and the smaller the elastic coefficient of the longitudinal escapement hairspring, the slower the energy release speed.

[0035] The speed increasing coupling unit comprises a secondary driving gear 23, a secondary driven gear 24, a tertiary driving gear 25 and a tertiary driven rack 26. The secondary driving gear 23 and the secondary driven gear 24 are rotatably connected to the housing through a secondary gear shaft 27, and the secondary driving gear 23 and the secondary driven gear 24 can rotate synchronously with the secondary gear shaft 27, wherein the secondary driving gear 23 is meshed with the longitudinal escapement driven gear 15. The tertiary driving gear 25 is rotatably connected to the housing through a tertiary gear shaft 28, and the tertiary driving gear 25 can rotate synchronously with the tertiary gear shaft 28, the tertiary driving gear 25 is meshed with the secondary driven gear 24, the tertiary driven rack 26 is arc-shaped, and is arranged coaxially with the tertiary gear shaft 28, one end of which is connected to the tertiary gear shaft 28 through a connecting rod, wherein one end of the connecting rod is connected to the tertiary driven rack 26, and the other end is connected to the tertiary gear shaft 28 through a one-way bearing. As a preferred embodiment, the ratchet 2, the primary driving gear 11, the longitudinal escapement driving gear 14, the longitudinal escapement driven gear 15, the secondary driving gear 23, the secondary driven gear 24, the tertiary driving gear 25 and the tertiary driven rack 26 are all located in a vertical plane; the longitudinal escapement handle 18 is arranged vertically, and its upper end is connected to the housing through a rotating shaft 19. In this way, the vibration starting and longitudinal and escapement stability of the longitudinal escapement mechanism are better. In specific implementation, the transmission ratio of the longitudinal escapement driven gear 15, the secondary driven gear 24, and the tertiary driven rack 26 satisfies that the tertiary driven rack 26 rotates exactly one circle for each longitudinal escapement of the longitudinal escapement unit; in this way, the continuous power generation of the generator can be ensured.

[0036] The magnetic levitation power generation unit includes a motor shaft 29, a motor rotor 30, a motor stator 31, a driving gear 32 and a magnetic bearing 33. The two ends of the motor shaft 29 are connected to the housing through a magnetic bearing 33 respectively. During processing, a bearing seat 34 is provided on the inner side of the housing corresponding to the position of the magnetic bearing 33. The magnetic bearing 33 is installed in the bearing seat 34, so that the installation stability of the magnetic bearing 33 is better. Among them, the magnetic bearing 33 is a mature existing product, which includes a permanent magnetic outer ring and a permanent magnetic inner ring. The permanent magnetic outer ring is fixedly connected to the bearing seat 34; the permanent magnetic inner ring is located on the inner side of the permanent magnetic outer ring, and there is a gap between the permanent magnetic outer ring, and the polarity of the adjacent side of the permanent magnetic outer ring and the permanent magnetic inner ring is the same, so that the permanent magnetic outer ring and the permanent magnetic inner ring repel each other, so that the gap between the permanent magnetic outer ring and the permanent magnetic inner ring is always maintained, forming a suspended state, and greatly reducing the friction of the bearing. The motor rotor 30 is fixedly connected to the motor shaft 29, and includes a rotor bracket and a permanent magnet block installed on the rotor bracket; when the number of permanent magnet blocks is two or more odd blocks, all permanent magnet blocks have the same magnetization direction; when the number of permanent magnet blocks is four or more even blocks, all permanent magnet blocks have the same magnetization direction or the magnetization directions of two adjacent permanent magnet blocks are opposite. The motor stator 31 includes a winding coil, which is evenly distributed around the motor shaft 29 and fixedly connected to the housing through the stator bracket, and when the motor rotor 30 rotates with the motor shaft 29, the winding coil can be directly opposite to the permanent magnet block; and the motor stator 31 and the motor rotor 30 are gap-matched, so that more magnetic flux lines pass through the motor stator 31, and the power generation efficiency is higher. In specific implementation, the ratio of the number of the winding coils to the number of permanent magnet blocks is 1:1, 2:3 or 3:2, so that a single-phase motor or a three-phase motor can be formed and the power generation efficiency is maximized. During the processing, a power supply interface is provided on the housing, and the winding coil is connected to the power supply interface for power output. The driving gear 32 is installed on the motor shaft 29 and can rotate synchronously with the motor shaft 29. The driving gear 32 is meshed with the three-stage driven rack 26 or can mesh with the driving gear 32 after the three-stage driven rack 26 rotates (that is, when the driving gear 32 is in the gap of the three-stage driven rack 26). During the processing, the teeth on the three-stage driven rack 26 and the driving gear 32 are all helical teeth, and at the meshing position of the three-stage driven rack 26 and the driving gear 32, the inclination direction of the helical teeth on the three-stage driven rack 26 is opposite to that of the helical teeth on the driving gear 32; thereby, the meshing and separation of the three-stage driven rack 26 and the driving gear 32 can be achieved more smoothly.During the specific implementation process, during the speed-increasing transmission process of the secondary driving gear 23, the secondary driven gear 24, the tertiary driving gear 25 and the tertiary driven rack 26, when the longitudinal escapement 17 is in free rotation, that is, in the longitudinal process, the tertiary driven rack 26 is engaged with the driving gear 32, thereby driving the driving gear 32 to rotate and generate electricity; when the longitudinal escapement 17 is in contact with the longitudinal escapement 17, that is, in the escapement process, the longitudinal escapement driven gear 15 rotates slowly, at this time, the tertiary driven rack 26 is in a separated state from the driving gear 32, that is, the driving The driven gear 32 is located between the two ends of the three-stage driven rack 26. The driving gear 32 and the three-stage driven rack 26 rotate continuously under the action of inertia. Since the motor shaft 29 is connected to the housing by a magnetic bearing 33, the friction force on the motor shaft 29 during rotation is extremely small, thereby ensuring the continuous power generation of the generator. When the longitudinal escapement 17 enters the free rotation state again, the three-stage driven rack 26 meshes with the driving gear 32 again, and the cycle continues; the longitudinal escapement releases energy through intermittent energy to achieve continuous power generation input. As an implementation method, the central angle corresponding to the three-stage driven rack 26 is greater than or equal to 270° to ensure the normal operation of the entire generator.

[0037] In order to ensure that the device can generate electricity in time, the combined rotational inertia of the longitudinal escapement gears (longitudinal escapement driving gear 14 and longitudinal escapement driven gear 15), the speed-increasing gears (secondary driving gear 23, secondary driven gear 24, tertiary driving gear 25 and tertiary driven rack 26), the generator rotor 30, etc. is required to be small, and the generator load is also required to be small; so that under the action of the power spring, within the time interval of the longitudinal and escapement transitions of the longitudinal escapement mechanism, the speed-increasing rack can rotate at high speed for several full cycles, and can rotate smoothly for at least one circle.

[0038] This solution has a simple structure, a small size and is easy to carry. The magnetic levitation power generation unit adopts a radial magnetic bearing 33, which makes the friction loss of the entire generator very small. During the operation, the speed is stable and the safety is higher. The power spring can be used for elastic energy storage, and the characteristics of the longitudinal escapement mechanism are used to slowly and orderly release the mechanical energy stored in the power spring 10 intermittently. With the cooperation of the radial magnetic bearing 33, the generator rotor 30 uses its low friction characteristics to play the role of a flywheel to achieve the purpose of kinetic energy storage, so that the input large short-term power can be converted into a long-term stable release of small power electricity, so as to carry out uninterrupted and continuous power generation, and the power generation stability is better, which is suitable for lighting, short-term communication and other occasions in remote mountainous areas without electricity.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
