Abstract
Description
Technical Field
[0001] This invention relates to the field of power generation technology, specifically to a high-efficiency energy storage generator set. Background Technology
[0002] With the development of renewable energy utilization and distributed energy systems, small, efficient, and low-cost power generation devices have shown broad application prospects in emergency power supply, power supply in remote areas, teaching experiments, and human-computer interactive energy recovery. However, existing small power generation systems generally suffer from low energy conversion efficiency, difficulty in starting up, and high requirements for input sources. In particular, they are difficult to achieve stable and efficient power output when faced with low-power input sources.
[0003] Traditional small generators typically employ direct drive, where the input power is directly connected to the generator rotor via a coupling or pulley. While this structure is simple to construct, it has significant drawbacks in practical operation. Standard generators are usually designed to operate at rated speed and rated load, and they contain non-negligible electromagnetic resistance, which increases significantly with increasing speed. When the input power source is limited, it is difficult to provide sufficient initial torque to overcome static friction and electromagnetic damping, causing the system to fail to start smoothly or operate only at extremely low speeds.
[0004] Secondly, even if the system manages to operate with difficulty, the output voltage and frequency are unstable and the power quality is poor because the input speed is far below the generator's optimal operating range. Furthermore, the actual output power is often less than 20%–30% of the rated value, resulting in a serious waste of the equipment's potential. In addition, human power or other intermittent energy sources mostly provide reciprocating motion or low-frequency linear thrust, while traditional generators only accept continuous rotational input and lack an effective motion conversion mechanism, further limiting energy adaptability.
[0005] Therefore, it is necessary to provide high-efficiency energy storage generator sets to solve the above problems. Summary of the Invention
[0006] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a high-efficiency energy storage generator set to solve the problems mentioned in the background art.
[0007] The technical solution adopted by this invention to solve its technical problem is: a high-efficiency energy storage generator set, including an electric cylinder, a bracket, a lever, a speed increaser, a drive shaft, a flywheel, and a generator. The bracket is located between the electric cylinder and the speed increaser, and the lever is rotatably mounted on the bracket. One end of the lever is hinged to the output end of the electric cylinder and moves up and down in a straight line. The other end is driven to the input end of the speed increaser. The output end of the speed increaser is driven to the input end of the generator through the drive shaft. The flywheel is fixedly connected to the drive shaft and located between the speed increaser and the generator.
[0008] Furthermore, one end of the lever has an opening facing the speed increaser, and a slider is slidably connected inside the opening, the slider having a through hole; The speed increaser has an input shaft at its input end, and a concentrically arranged turntable is fixedly connected to the input shaft. A handle is fixedly connected to the end face of the turntable, and the handle is located inside a through hole.
[0009] Furthermore, symmetrical grooves are provided at both the upper and lower ends of the opening; Both ends of the slider have protrusions extending outwards, and the protrusions slide within the groove.
[0010] Furthermore, the drive shaft is also equipped with couplings, which are located at the upper and lower ends of the flywheel.
[0011] Furthermore, the output end of the speed increaser has an output shaft, which is connected to one end of the transmission shaft.
[0012] Furthermore, the lever has a through hole in the radial direction; The top of the bracket is fixedly connected to two baffles and a rotating shaft. The rotating shaft is fixedly connected between the two baffles and is located inside the through hole. The lever is located between the baffles.
[0013] Furthermore, the electric cylinder has a servo motor, a reducer, a cylinder body, and a push rod. The servo motor is connected to the input end of the reducer as a drive, the push rod is slidably mounted in the cylinder body, and the output end of the reducer is connected to the bottom of the cylinder body to drive the push rod to slide up and down in the cylinder body.
[0014] Furthermore, an installation cavity is provided on the outer circumferential surface of one end of the lever, and a connecting post is provided axially inside the installation cavity, with the top end of the push rod hinged to the connecting post.
[0015] The beneficial effects of the present invention are as follows: The high-efficiency energy storage generator set provided by the present invention has a flywheel. When the device is started in a static state, the flywheel rotates in the direction of the output shaft rotation, which improves the stability of the input speed and the quality of power generation, and greatly reduces the initial starting force. This allows the device to overcome the initial electromagnetic damping and mechanical friction to start successfully, avoiding the situation where the input source power is limited and it is difficult to provide sufficient initial torque to overcome static friction and electromagnetic damping, which leads to the system failing to start smoothly or only being able to operate at extremely low speeds. By using an electric cylinder to swing a lever, and embedding a sliding slider in the lever, the linear reciprocating motion is converted into rotary motion. The power is transmitted to the speed increaser, where the input shaft receives the low-speed, high-torque motion transmitted by the push rod. After being accelerated by the internal gear system, the high-speed, low-torque rotation is output from the output shaft, and the power is transmitted to the generator to achieve efficient power generation.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0020] like Figure 1-9 As shown, the present invention provides a technical solution: a high-efficiency energy storage generator set, including an electric cylinder 1, a bracket 2, a lever 3, a speed increaser 4, a transmission shaft 43, a flywheel 5, and a generator 6. The bracket 2 is located between the electric cylinder 1 and the speed increaser 4, and the lever 3 is rotatably mounted on the bracket 2. One end of the lever 3 is hinged to the output end of the electric cylinder 1 and moves up and down in a straight line. The other end is driven to the input end of the speed increaser 4. The output end of the speed increaser 4 is driven to the input end of the generator 6 through the transmission shaft 43. The flywheel 5 is fixedly connected to the transmission shaft 43 and is located between the speed increaser 4 and the generator 6.
[0021] One end of the lever 3 has an opening 301 facing the speed increaser 4, and a slider 31 is slidably connected inside the opening 301. The slider 31 has a through hole 302. The input end of the speed increaser 4 has an input shaft 41, and a concentrically arranged turntable 411 is fixedly connected to the input shaft 41. A handle 412 is fixedly connected to the end face of the turntable 411, and the handle 412 is located in the through hole 302.
[0022] The opening 301 has symmetrical grooves 3011 at both the upper and lower ends; Both the upper and lower ends of the slider 31 have protrusions 311 extending outwards, and the protrusions 311 slide within the groove 3011. This restricts the slider 31 to slide within the opening 301.
[0023] A coupling 51 is also provided on the drive shaft 43, and the coupling 51 is located at the upper and lower ends of the flywheel 5 respectively.
[0024] The output end of the speed increaser 4 has an output shaft 42, which is connected to one end of the transmission shaft 43.
[0025] Lever 3 has a through hole 302 in the radial direction; The top of the bracket 2 is fixedly connected to two baffles 21 and a rotating shaft 22. The rotating shaft 22 is fixedly connected between the two baffles 21 and is located inside the through hole 302. The lever 3 is located between the baffles 21.
[0026] The electric cylinder 1 has a servo motor 11, a reducer 12, a cylinder body 13 and a push rod 14. The servo motor 11 is connected to the input end of the reducer 12 as a drive. The push rod 14 is slidably installed in the cylinder body 13. The output end of the reducer 12 is connected to the bottom of the cylinder body 13 to drive the push rod 14 to slide up and down in the cylinder body 13.
[0027] A mounting cavity 303 is provided on the outer circumference of one end of the lever 3. A connecting post 32 is provided axially inside the mounting cavity 303. The top end of the push rod 14 is hinged to the connecting post 32.
[0028] In one embodiment, the operating principle of the device
[0029] Specifically, when the servo motor 11 is started in a stationary state, the flywheel 5 is held by hand and rotated, thereby driving the transmission shaft 43 to rotate slowly, so that the speed increaser 4 is started and drives the input shaft 41 to rotate, and the slider 31 slides in the opening 301 to overcome the initial electromagnetic damping and mechanical friction. As the servo motor 11 starts, the push rod 14 moves upward from the cylinder 13, and the end of the lever 3 connected to the push rod 14 moves upward. With the rotating shaft 22 as the axis, the end of the lever 3 away from the electric cylinder 1 moves downward, and the handle 412 is pressed down through the slider 31 to drive the turntable 411 to rotate, and then drive the input shaft 41 to rotate. As the turntable 411 rotates, the slider 31 slides within the opening 301 as the handle 412 moves. When the push rod 14 rises to the upper limit position, the turntable 411 rotates 180°. Then, the push rod 14 is lowered, causing the lever 3 at one end of the speed increaser 4 to move upward, thus driving the turntable 411 to continue rotating. When the push rod 14 falls to the lower limit position, the turntable 411 has completed a 360° rotation. At this point, the push rod 14 is controlled to move up and down reciprocally, and the slider 31 also moves reciprocally within the opening 301. The rotation of turntable 411 transmits power to input shaft 41. After passing through the gear set in speed increaser 4, the power is transmitted from output shaft 42 to transmission shaft 43. The rotation of transmission shaft 43 transmits power to generator 6. At this time, flywheel 5 rotates with the rotation of transmission shaft 43.
[0030] In summary, by incorporating a flywheel 5, this device improves the stability of the input speed and the quality of power generation when starting from a stationary state. By rotating the flywheel 5 in the direction of rotation of the output shaft 42, the initial starting force is significantly reduced, enabling the device to overcome initial electromagnetic damping and mechanical friction to start successfully. This avoids the situation where, when the input source power is limited, it is difficult to provide sufficient initial torque to overcome static friction and electromagnetic damping, resulting in the system failing to start smoothly or only being able to operate at extremely low speeds. By setting an electric cylinder 1 to swing the lever 3, and embedding a sliding slider 31 in the lever 3, the linear reciprocating motion is converted into rotational motion, and the power is transmitted to the speed increaser 4. The input shaft 41 receives the low-speed, high-torque motion transmitted by the push rod, and after being accelerated by the internal gear system, it outputs high-speed, low-torque rotation from the output shaft 42, and transmits the power to the generator 6 to achieve efficient power generation.

Various modifications and variations can be made to the present invention by those skilled in the art.
