Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to a self-circulating auxiliary power generation device. Background Technology

[0002] With increasing energy demand and the growing popularity of energy conservation and environmental protection concepts, technologies that utilize mechanical auxiliary power or gravitational potential energy to generate electricity are gradually gaining attention. Existing auxiliary power generation equipment mostly relies on basic mechanical transmission structures to convert potential energy or kinetic energy into electrical energy, but there are still significant limitations in practical applications.

[0003] In terms of structural transmission and power generation efficiency, traditional generators typically employ a working mode where the stator with a fixed outer casing is fixed while only the internal rotor shaft rotates. This unidirectional drive method limits the relative speed between the rotor and stator, making it difficult to increase the cutting frequency of magnetic field lines and the overall power generation without significantly increasing the input speed of the external power source.

[0004] Regarding power regulation and operational stability, some devices that utilize the principle of center of gravity offset to obtain auxiliary power lack reliable dynamic adjustment mechanisms. During high-speed operation, the displacement of the counterweight components cannot be precisely and smoothly controlled in real time. The counterweight components are prone to trajectory deviation or mechanical jamming due to centrifugal force and vibration. This not only leads to inaccurate gravity offset but also causes unstable equipment operation, further exacerbating mechanical wear on internal parts and shortening the equipment's lifespan.

[0005] In terms of energy distribution and safety control, current self-circulating power generation systems often lack robust voltage stabilization and feedback mechanisms, as well as high-voltage safety isolation mechanisms. The initial electrical energy output from the generator often fluctuates, making it difficult to maintain stable closed-loop operation for extended periods if directly used for internal drive or external output. Furthermore, when overloads or short-circuit anomalies occur at external power terminals, the lack of effective physical isolation and on / off control allows fault currents to easily reverse and damage internal inverters and generator core components, resulting in poor overall system safety and power supply reliability. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a self-circulating auxiliary power generation device, which solves the problems of low power generation efficiency due to the low relative speed between the generator rotor and stator, unstable operation and lack of precise control of the gravity offset adjustment mechanism, and the lack of a stable closed-loop self-circulation of electrical energy and a high-voltage output safety isolation mechanism in existing auxiliary power generation equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-circulating auxiliary power generation device, comprising a power support, on which a three-phase four-wire generator is mounted. A stabilizing metal plate is mounted on the outside of the power support, the stabilizing metal plate connecting to and driving the housing of the three-phase four-wire generator to rotate. A low-V slider motor, a screw, and planetary speed-increasing gears are mounted on the outside of the stabilizing metal plate. The output end of the low-V slider motor is fixedly connected to the screw. A gravity slider is threaded onto the outside of the screw and drives the gravity slider to move within the stabilizing metal plate. The change in the gravity of the gravity slider causes the stabilizing metal plate to rotate. The stabilizing metal plate transmits reverse rotational speed to the central shaft of the three-phase four-wire generator through the planetary speed-increasing gears. The three-phase four-wire generator is electrically connected to the low-V slider motor through a battery and a low-V inverter.

[0008] Preferably, the metal plate of the stabilizing component is covered with a machine plate cover, the machine plate cover is fixedly connected to the metal plate of the stabilizing component and rotates synchronously with the metal plate of the stabilizing component, and the machine plate cover provides physical protection for the low-V slider power motor and the extension gravity slider inside the metal plate of the stabilizing component.

[0009] Preferably, a guide rail slider is fixedly installed inside the metal plate of the stabilizing component. The guide rail slider is slidably connected to the extension gravity slider. The guide rail slider provides guidance and support for the linear motion trajectory of the extension gravity slider, preventing the extension gravity slider from deviating during the offset process.

[0010] Preferably, a control switch and electronic device are mounted on the metal plate of the stabilizing component. The control switch and electronic device are electrically connected to the low-V slider power motor. The control switch and electronic device send control signals to the low-V slider power motor according to the rotation state of the three-phase four-wire generator, thereby precisely controlling the displacement of the extension gravity slider.

[0011] Preferably, a low-V input line is fixedly connected between the low-V inverter and the low-V slider motor. The low-voltage electrical energy output by the low-V inverter is transmitted to the low-V slider motor through the low-V input line, ensuring that the low-V slider motor obtains stable driving energy.

[0012] Preferably, the output terminal of the three-phase four-wire generator is equipped with an electrical connector, and the electrical energy generated by the three-phase four-wire generator is collected in the electrical connector. The electrical connector provides a unified electrical energy output interface, which facilitates the distribution of the electrical energy generated by the three-phase four-wire generator to the outside.

[0013] Preferably, a three-phase four-wire return line is fixedly connected to the outside of the electrical connector. The electrical energy generated by the three-phase four-wire generator is transmitted through the electrical connector and the three-phase four-wire return line. The three-phase four-wire return line undertakes the cable transmission function of sending electrical energy back to the subsequent regulation module.

[0014] Preferably, a voltage inverter is fixedly connected to one end of the three-phase four-wire return line away from the electrical connector. The electrical energy output by the three-phase four-wire generator passes through the three-phase four-wire return line and enters the voltage inverter for frequency conversion and voltage regulation. The voltage inverter outputs a stable voltage and supplies it to the storage battery for storage.

[0015] Preferably, the battery is also electrically connected to a high-voltage inverter, and some of the excess electrical energy stored in the battery enters the high-voltage inverter, which converts low-voltage DC power into high-voltage AC power.

[0016] Preferably, a high-voltage switch is fixedly connected to the output terminal of the high-voltage inverter. The high-voltage switch controls the on / off state of the high-voltage inverter outputting high-voltage power to the outside. The high-voltage switch cuts off the circuit when an external circuit overload occurs, providing a safe isolation protection function for high-voltage power consumption.

[0017] This invention provides a self-circulating auxiliary power generation device. It has the following beneficial effects: 1. This invention improves the power generation efficiency of a three-phase four-wire generator by cooperating with the stabilizing component metal plate and the planetary speed-increasing gear. When the stabilizing component metal plate rotates under the action of offset gravity, it not only directly drives the generator casing to rotate synchronously, but also uses the externally installed planetary speed-increasing gear to transmit high-speed rotation in the opposite direction to the generator central shaft. Without increasing the overall external speed of the equipment, it increases the relative speed between the rotor and stator inside the generator, thereby improving the power output per unit time of the device.

[0018] 2. This invention ensures the precision and stability of the gravity offset adjustment process through the coordinated setting of the control equipment and the guide rail slider. The control switch and electronic equipment can send control signals to the low-V slider power motor to drive the screw according to the real-time rotation status of the three-phase four-wire generator, thereby precisely adjusting the displacement of the gravity slider within the metal plate. The guide rail slider inside the stable component metal plate provides physical guidance and support for the linear movement of the gravity slider, preventing the slider from becoming misaligned or mechanically jammed during the gravity offset process, thus ensuring the accuracy of the overall specific gravity change and the stability of the rotation operation.

[0019] 3. This invention achieves energy self-circulation and safe external power supply through the design of the power feedback and inverter output module. The initial electrical energy output by the generator is regulated by the voltage frequency converter and then stored in the battery. The battery then provides the power for the next cycle to the slider motor through the inverter, forming a complete internal closed-loop drive. Excess electrical energy in the battery enters the high-voltage inverter and is converted into high-voltage AC power for external output. The high-voltage switch connected at the end can cut off the circuit in time when an overload or short circuit occurs at the external receiving end, preventing the fault current from damaging the internal power generation equipment in reverse, and providing safe physical isolation protection.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 and attached Figure 2This invention provides a self-circulating auxiliary power generation device, including a power support 10. Based on the robust support provided by the power support 10, a storage battery 14 outputs stored electrical energy, which is converted into a suitable voltage by a low-V inverter 15 and then supplies power to a low-V slider motor 7. The low-V slider motor 7, having obtained electrical energy, starts operating and drives a screw 2 at its output end to rotate continuously. The rotating screw 2 uses a threaded transmission mechanism to drive an externally mounted extension gravity slider 8 to perform linear displacement within a stabilizing component metal plate 4. As the position of the extension gravity slider 8 continuously changes, it alters the overall weight distribution of the device and generates an eccentric gravitational torque. This eccentric gravitational torque causes the stabilizing component metal plate 4 to... The stabilizing component metal plate 4 rotates continuously around the axis. On the one hand, it directly drives the housing of the three-phase four-wire generator 9 to rotate synchronously. On the other hand, it uses the planetary speed-increasing gear 6 to change the speed and reverse the direction of the transmission path. This converts the rotational power of the stabilizing component metal plate 4 into a reverse high speed and transmits it to the central shaft of the three-phase four-wire generator 9. This causes the central shaft of the three-phase four-wire generator 9 and the housing to form a high-speed rotation state in opposite directions to generate electricity efficiently. Finally, the electricity output by the three-phase four-wire generator 9 flows back to the storage battery 14 for storage, and then provides the driving energy for the low-V slider power motor 7 for the next cycle, thereby realizing the self-circulating power generation operation of the auxiliary power.

[0024] Please see the appendix Figure 1 In a preferred embodiment of the present invention, when the stabilizing component metal plate 4 rotates continuously under the action of gravity offset, the chassis cover 1 covering it will rotate synchronously with the stabilizing component metal plate 4. At this time, the rotating chassis cover 1 forms a moving physical isolation barrier around the equipment. This barrier blocks impurities in the external environment and potential external mechanical collisions, thereby providing direct physical protection for the low-V slider power motor 7 that is performing electric drive tasks and the extension gravity slider 8 that is changing position inside the stabilizing component metal plate 4. This ensures the structural safety and operational stability of the internal core center of gravity adjustment mechanism and electrical drive components during the self-circulating power generation process.

[0025] Please see the appendix Figure 1In a preferred embodiment of the present invention, during the process of the screw 2 driving the extension gravity slider 8 to perform linear displacement motion inside the stabilizing component metal plate 4 to continuously change the overall specific gravity distribution of the equipment, the guide rail slider 3 fixed inside the stabilizing component metal plate 4 closely fits and cooperates with the sliding action of the extension gravity slider 8, providing forced linear guidance and stable load-bearing support for the linear motion trajectory of the extension gravity slider 8. This guiding and supporting effect overcomes the centrifugal force and vibration interference generated when the stabilizing component metal plate 4 rotates, strictly limits the degree of freedom of movement of the extension gravity slider 8 in unexpected directions, thereby preventing the extension gravity slider 8 from becoming misaligned or mechanically stuck during the dynamic offset and change of the center of gravity operation, thus ensuring the accuracy of specific gravity change adjustment and the stability of the entire auxiliary power unit in self-circulating power generation operation.

[0026] Please see the appendix Figure 1 In a preferred embodiment of the present invention, during the operation of the system's self-circulating power generation, the control switch and electronic device 5 mounted on the stabilizing component metal plate 4 monitor and acquire the current rotation state and operating parameters of the three-phase four-wire generator 9 in real time. Subsequently, the control logic inside the control switch and electronic device 5 generates corresponding adjustment commands based on the acquired power generation load and speed requirements and transmits them to the low-V slider power motor 7 in the form of electrical signals. Upon receiving the control signals, the low-V slider power motor 7 changes its own start / stop state and output speed accordingly, thereby driving the screw 2 to rotate at corresponding high and low speeds to precisely control the real-time displacement of the extension gravity slider 8 inside the stabilizing component metal plate 4, thereby achieving dynamic fine-tuning of the overall specific gravity eccentricity of the equipment to ensure that the three-phase four-wire generator 9 can maintain a continuous and stable rotational power generation state.

[0027] Please see the appendix Figure 1 and attached Figure 2 In a preferred embodiment of the present invention, when the self-circulating auxiliary power generation device is in the closed-loop energy transmission stage of continuous operation, the front-end low-V inverter 15 first converts the electrical energy from the storage battery 14 into low-voltage electrical energy suitable for use by the actuator. Then, the output low-voltage electrical energy enters and passes through the low-V input line 16, which has insulation and current conduction functions, for cross-regional power transmission. Finally, the low-voltage electrical energy is accurately delivered along the low-V input line 16 to the receiving end of the low-V slider motor 7 installed outside the stable component metal plate 4, thereby establishing a reliable power supply link in the entire power cycle control system and ensuring that the low-V slider motor 7 always obtains abundant and stable driving energy during the dynamic operation of frequently adjusting the displacement of the gravity slider 8.

[0028] Please see the appendix Figure 2In a preferred embodiment of the present invention, during the operation phase in which the central shaft and the outer casing of the three-phase four-wire generator 9 rotate at high speed in opposite directions to continuously generate electrical energy, the AC power generated inside the three-phase four-wire generator 9 is directed and converged along the output end and flows into the electrical connector 11 assembled at the port. The electrical connector 11, which plays the role of power convergence and connection hub, performs safe physical integration of the transmitted current, thereby establishing a standardized and unified power output interface between the generator body and the external transmission cable. This unified power output interface avoids the risk of poor contact and short circuit caused by direct bare connection of multiple wires, and thus, while ensuring the stability of the transmission link, conveniently and orderly distributes the power generated by the three-phase four-wire generator 9 to the external load equipment or the downstream self-circulating feedback unit.

[0029] Please see the appendix Figure 2 In a preferred embodiment of the present invention, during the operation of the three-phase four-wire generator 9 continuously generating AC power and collecting it to a unified interface, this output power smoothly passes through the electrical connector 11, which acts as a connection hub, and is directly introduced into the external three-phase four-wire return line 12 for directional transmission. At this time, the three-phase four-wire return line 12, which has multi-phase conductivity and insulation protection, constructs a closed-loop energy return channel in the entire self-circulation system. It is specifically responsible for the cable transmission function of safely sending the generated raw power back to the downstream regulation module across physical space distance, thereby laying a reliable physical circuit foundation for subsequent power parameter processing and the entire auxiliary power unit to achieve energy self-sufficiency and closed-loop operation.

[0030] Please see the appendix Figure 1 and attached Figure 2 In a preferred embodiment of the present invention, during the operation of the original AC power output by the three-phase four-wire generator 9 passing through the electrical connector 11 and being looped back along the three-phase four-wire return line 12, the initial power parameters fluctuate due to the dynamic changes of mechanical rotation. This portion of the power is directly introduced into the downstream voltage frequency converter 13 along the end of the three-phase four-wire return line 12 away from the electrical connector 11. The voltage frequency converter 13, which plays a core role in power regulation, then performs precise frequency conversion and voltage regulation on the input fluctuating power, thereby eliminating the interference of fluctuations in power frequency and amplitude and converting it into smooth and stable power that meets the energy storage standard. Subsequently, the voltage frequency converter 13 continuously delivers the processed stable voltage to the end battery 14 for efficient energy storage and safe storage, thereby establishing a reliable energy reserve in the self-circulating auxiliary power generation device and successfully completing the closed-loop recovery of power.

[0031] Please see the appendix Figure 2In a preferred embodiment of the present invention, during the operation phase in which the self-circulating auxiliary power generation device completes stable internal energy storage and ensures sufficient driving energy for the system itself, a portion of the excess low-voltage DC power stored in the storage battery 14, which has completed closed-loop energy recovery, will be directed into the high-voltage inverter 17 in the subsequent stage through an additional electrical channel. The high-voltage inverter 17, which performs power conversion and voltage boosting functions, will then invert this portion of redundant DC energy, thereby accurately converting the low-voltage DC power output from the storage battery 14 into high-voltage AC power that meets the standards for use by external power users. Thus, while maintaining the continuous self-circulating operation of the auxiliary power within the entire device, the excess generated energy is successfully output as high-voltage AC power.

[0032] Please see the appendix Figure 2 In a preferred embodiment of the present invention, during the terminal operation phase when the high-voltage inverter 17 successfully boosts the excess low-voltage DC power into high-voltage AC power and prepares to output power to the outside, the strong high-voltage power collected at the output terminal of the high-voltage inverter 17 is directly introduced into the high-voltage application disconnector 18, which undertakes the terminal safety control function. At this time, the high-voltage application disconnector 18, which is in working state, precisely controls the real-time on / off state of the high-voltage inverter 17 outputting high-voltage power to the external load equipment through its own opening and closing action. Once a short circuit occurs in the external receiving circuit or a serious overload abnormality occurs when the power load exceeds the rated range of the system during the power supply process, the high-voltage application disconnector 18 will respond quickly and immediately forcefully disconnect the entire high-voltage output circuit. This establishes a reliable high-voltage power safety isolation and protection barrier between the power output port of the self-circulating auxiliary power generation device and the external power network, thereby preventing the external fault current from back impacting and damaging the upstream high-voltage inverter 17 and other core self-circulating energy storage and power generation operation equipment.

[0033] Working principle: When the self-circulating system is running on the power support 10 which provides robust support, the battery 14 first outputs the energy stored inside, which enters the low-V inverter 15 and is converted into suitable low-voltage electrical energy. Subsequently, the low-voltage electrical energy is stably delivered to the low-V slider motor 7 through the low-V input line 16 to provide drive power.

[0034] Meanwhile, the control switch and electronic equipment 5 mounted on the stabilizing component metal plate 4 monitor the rotation status of the three-phase four-wire generator 9 in real time and send adjustment control signals to the low-V slider motor 7 accordingly. Upon receiving the signal and obtaining electrical energy, the low-V slider motor 7 starts running, driving the screw 2 at the output end to rotate continuously. The rotating screw 2 uses a threaded transmission mechanism to drive the extension gravity slider 8 to perform linear displacement within the stabilizing component metal plate 4. During the displacement process, the guide rail slider 3 installed inside the stabilizing component metal plate 4 provides forced guidance and support for the movement trajectory of the extension gravity slider 8 to prevent it from deviating. As the position of the extension gravity slider 8 continuously changes, it precisely adjusts the... The overall weight distribution of the equipment generates an eccentric gravitational torque, which causes the stabilizing component metal plate 4 to rotate continuously around the axis. At this time, the chassis cover 1, which is installed on the outside and rotates synchronously with the stabilizing component metal plate 4, provides physical protection against external interference for the internal core components such as sliders and motors. The stabilizing component metal plate 4, which is in a rotating state, directly drives the outer casing of the three-phase four-wire generator 9 to rotate synchronously. On the other hand, it also changes the speed and direction of the transmission path through the planetary speed-increasing gear 6 installed on the outside and transmits high-speed rotation in the opposite direction to the central shaft of the three-phase four-wire generator 9, so as to cause the central shaft of the three-phase four-wire generator 9 and the outer casing to form a high-speed rotation state in opposite directions to efficiently generate electrical energy.

[0035] Subsequently, the AC power generated by the three-phase four-wire generator 9 is directionally collected into the electrical connector 11, which provides a unified power output interface, and smoothly passes through the three-phase four-wire return line 12, which is dedicated to energy feedback transmission, directly into the subsequent voltage inverter regulator 13. The voltage inverter regulator 13, playing a core regulatory role, performs precise frequency conversion and voltage regulation on the input raw power, thereby outputting a stable voltage and continuously transmitting it back to the storage battery 14 for energy storage. This provides the driving energy for the low-V slider motor 7 for the next cycle, thus maintaining the closed-loop self-circulation operation of the entire auxiliary power system. While ensuring sufficient energy for the system's own operation, the storage battery 14... The stored excess electrical energy is diverted into the high-voltage inverter 17, which converts the input low-voltage DC power into high-voltage AC power that meets external requirements. Finally, this converted high-voltage electrical energy is output to external load equipment through the high-voltage switch 18 at the output end. In the process of controlling the output on / off state, the high-voltage switch 18 will quickly and physically disconnect the circuit in case of external circuit overload or abnormality, thereby providing reliable high-voltage power safety isolation protection function. In the end, the entire process of gravity offset drive, mechanical reverse high-speed power generation, internal closed-loop self-circulation of electrical energy, and safe output of excess electrical energy is realized in a stable and efficient manner.
