Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0025] like Figures 1 to 6 As shown, a diesel generator set instantaneous overload protection enhancer includes a protective frame 1, a base plate 2, and a housing 6. A display 8 and a control panel 9 are fixedly installed on the upper end of the housing 6, and a plug panel 7 is fixedly installed on the side of the housing 6. A junction box 10 is fixedly connected inside the plug panel 7. A circuit board 14 is fixedly installed inside the lower end of the housing 6. Several supercapacitors 13 are fixedly installed on the surface of the circuit board 14. A battery box 15 is fixedly installed in the middle of the housing 6. An energy storage battery pack 12 composed of several battery modules is installed inside the battery box 15. An intelligent controller 11 is fixedly installed inside the upper end of the housing 6. The intelligent controller 11 is electrically connected to the display 8, control panel 9, junction box 10, energy storage battery pack 12, and supercapacitors 13.

[0026] In this setup, the display 8 can show the generator set's operating parameters in real time, such as speed, voltage, and current, allowing operators to intuitively understand the equipment status; the control panel 9 facilitates parameter setting, start-stop control, and other operations, enabling human-machine interaction; the junction box 10 provides a convenient interface for external circuit connections, ensuring the stability and reliability of the circuit connection between the power booster, the generator set, and electrical equipment; the supercapacitor 13 has rapid charging and discharging characteristics, enabling it to quickly release electrical energy to replenish and stabilize the voltage during instantaneous overload; the energy storage battery pack 12 adopts a modular design, allowing for flexible deployment of the appropriate number of battery modules according to the load size, improving energy utilization efficiency, reducing unnecessary energy loss, and facilitating maintenance and replacement; the intelligent controller 11, as the core control component, receives signals from various components, analyzes and processes the information, and issues control commands to coordinate the orderly operation of each component, ensuring the realization of the overall function of the power booster.

[0027] like Figures 1 to 6 As shown, in a specific embodiment, an air supply component is fixedly installed on one side of the outer casing 6. The air supply component includes an air compressor 18, an air tank 19, and an air supply pipe 20. The output end of the air compressor 18 is connected to the air tank 19. The air tank 19 is connected to the diesel engine 3 through the air supply pipe 20. A solenoid valve 21 is installed on the air supply pipe 20. The intelligent controller 11 is electrically connected to the air compressor 18 and the solenoid valve 21.

[0028] In this configuration, the air compressor 18 compresses air and delivers it to the air tank 19 for storage, providing an air source for replenishment. The air tank 19 stores a certain amount of compressed air to ensure sufficient air for replenishment during overload. The air delivery pipe 20 is the channel for air delivery, guiding the compressed air in the air tank 19 to the diesel engine 3. The solenoid valve 21, controlled by the intelligent controller 11, can quickly open or close the air delivery pipe 20 to achieve precise control of air replenishment. When the generator set experiences overload, the intelligent controller 11 controls the solenoid valve 21 to open, allowing the compressed air in the air tank 19 to enter the diesel engine 3 through the air delivery pipe 20, increasing oxygen supply, making fuel combustion more complete, improving the output power of the diesel engine 3, and effectively coping with overload conditions.

[0029] like Figures 1 to 6 As shown, in a specific embodiment, the lower end of the protective frame 1 is fixedly installed on the upper surface of the base plate 2, and the lower end of the base plate 2 is fixedly connected with a shock-absorbing support foot.

[0030] In this setup, the protective frame 1 protects the entire booster and its internal components, such as the generator set, from external collisions and impacts that could damage the equipment. The base plate 2 provides a stable mounting foundation for each component, ensuring the accuracy and stability of their installation positions. The vibration-damping support feet effectively absorb the vibrations generated during generator set operation, reducing the impact of vibrations on the connections between the equipment components, lowering noise, and preventing vibrations from being transmitted to the ground and causing interference to the surrounding environment, thus improving the stability and safety of the equipment operation.

[0031] like Figures 1 to 6 As shown, in a specific embodiment, a load prediction module is fixedly installed on the upper surface of the base plate 2 near the generator 17. The load prediction module includes a current sensor 24 and a signal transmitter 25. The current sensor 24 is connected to the output line of the generator 17, and the signal transmitter 25 is connected to the intelligent controller 11.

[0032] In this setup, the current sensor 24 can monitor the current changes in the output line of the generator 17 in real time, capturing current fluctuation signals caused by equipment startup, etc.; the signal transmitter 25 transmits the signals monitored by the current sensor 24 to the intelligent controller 11 in a timely manner. Through the load prediction module, the intelligent controller 11 can detect potential overload situations in advance and make preparations in advance, such as pre-starting the gas replenishment component and putting the energy storage system into standby mode, thereby shortening the response time and improving the timeliness and effectiveness of overload resistance.

[0033] like Figures 1 to 6 As shown, in a specific embodiment, a power generation mechanism is provided on the upper surface of the base plate 2. The power generation mechanism includes a diesel engine 3 and a generator 17. The lower ends of the diesel engine 3 and the generator 17 are fixedly connected to the upper surface of the base plate 2. An oil tank 4 is fixedly installed on the upper surface of the base plate 2.

[0034] In this setup, diesel engine 3 serves as the power source, generating mechanical energy through the combustion of fuel. Generator 17 is connected to diesel engine 3 and converts the mechanical energy output by diesel engine 3 into electrical energy to power electrical equipment. Fuel tank 4 stores diesel fuel, providing a continuous fuel supply to diesel engine 3 and ensuring the continuous operation of the power generation mechanism. Base plate 2 provides a stable mounting platform for the various components of the power generation mechanism, ensuring that diesel engine 3 and generator 17 maintain a stable relative position during operation and improving energy conversion efficiency.

[0035] like Figures 1 to 6 As shown, in a specific embodiment, heat dissipation holes 23 are provided on both sides of the outer casing 6, and a cooling fan 26 is fixedly installed inside the outer casing 6 at the corresponding heat dissipation holes 23. The intelligent controller 11 is electrically connected to the cooling fan 26.

[0036] In this configuration, the heat dissipation hole 23 provides a channel for air circulation inside the housing 6, facilitating heat dissipation; the cooling fan 26 operates under the control of the intelligent controller 11, which can accelerate the airflow speed inside the housing 6 and dissipate the heat generated by components such as the supercapacitor 13, the energy storage battery pack 12, and the intelligent controller 11 through the heat dissipation hole 23, avoiding the impact of excessive temperature on the performance and service life of each component, and ensuring that the booster operates stably in a suitable temperature environment.

[0037] like Figures 1 to 6 As shown, in a specific embodiment, the fuel tank 4 is connected to the diesel engine 3 through a fuel supply pipe, the output end of the diesel engine 3 is connected to the input end of the generator 17, and an exhaust pipe 16 is fixedly connected to the upper end of the diesel engine 3. A heat recovery conversion device 5 is sleeved around the exhaust pipe 16.

[0038] In this configuration, the fuel delivery pipe transports diesel fuel from the fuel tank 4 to the diesel engine 3, providing fuel for the combustion of the diesel engine 3; the connection between the diesel engine 3 and the generator 17 enables the transfer of mechanical energy to electrical energy; the exhaust pipe 16 is used to discharge the exhaust gas generated by the combustion of the diesel engine 3; the heat recovery and conversion device 5 can absorb the heat in the exhaust gas discharged from the exhaust pipe 16 and convert it into electrical energy, which can be used to supplement the energy storage system such as the energy storage battery pack 12, thereby improving the energy utilization rate, reducing energy consumption, and making it more energy-efficient and environmentally friendly.

[0039] like Figures 1 to 6 As shown, in a specific embodiment, an oil quantity regulating valve 22 is installed on the oil delivery conduit, and the intelligent controller 11 is electrically connected to the oil quantity regulating valve 22.

[0040] In this configuration, the fuel quantity regulating valve 22 can regulate the flow rate of diesel fuel in the fuel delivery pipe under the control of the intelligent controller 11. When the generator set is under overload, the intelligent controller 11 controls the fuel quantity regulating valve 22 to increase or decrease the fuel supply according to the actual situation, ensuring that the diesel engine 3 operates under the optimal fuel supply condition. This provides sufficient power to cope with the overload, avoids fuel waste and incomplete combustion, improves fuel utilization, and reduces pollutant emissions.

[0041] The specific implementation principle of the diesel generator set instantaneous overload protection enhancer in this embodiment is as follows:

[0042] When the diesel generator suddenly encounters a heavy load such as multiple devices starting simultaneously, the current sensor 24 of the load prediction module detects current fluctuations and transmits them to the intelligent controller 11 via the signal transmitter 25. The intelligent controller 11 anticipates potential overloads and prepares accordingly. If an overload is detected, the intelligent controller 11 immediately coordinates the operation of various components: it controls the opening of the solenoid valve 21 of the air replenishment component, allowing compressed air from the air tank 19 to enter the diesel engine 3 through the air supply pipe 20, while the air compressor 18 replenishes the air tank 19, resulting in more complete fuel combustion and increased output power; it controls the discharge and recharging of the corresponding number of battery modules in the supercapacitor 13 and the energy storage battery pack 12 to stabilize the voltage; and it controls the fuel supply to the diesel engine 3 by adjusting the fuel quantity regulating valve 22 to prevent it from running out of power. Throughout the process, the cooling fan 26 operates in a timely manner according to the internal temperature of the casing 6 to ensure the normal operation of all components. In addition, the electrical energy recovered by the heat recovery conversion device 5 is added to the energy storage system, further enhancing the ability to withstand instantaneous overloads.
