Description

Technical Field

[0001] The present invention relates to the technical field of inverter power supplies, and specifically to a three-in-one adaptive portable inverter power supply. Background Art

[0002] With the continuous progress of technology and the rapid development of industry, the power supply requirements of various electronic devices and power systems are becoming increasingly diverse. In many application scenarios, such as the nuclear power field, it is necessary to convert DC power supplies of different voltage levels into stable AC power supplies to meet the operation requirements of equipment. However, traditional inverter power supplies have many limitations.

[0003] On the one hand, common inverter power supplies can often only adapt to DC inputs of a single voltage level, and it is difficult to meet the discharge requirements of three different battery systems of DC48V, 110V, and 220V in complex systems such as nuclear power. This results in the need to equip multiple inverter power supplies of different specifications in practical applications, which not only increases the equipment cost and management difficulty but also reduces the flexibility and reliability of the system. For example, in the emergency power supply system of a nuclear power plant, if the inverter power supply cannot automatically adapt to batteries of different voltages, once a power supply of a certain voltage level fails, it may not be possible to switch to other backup power supplies in time, thus affecting the normal operation of the entire system.

[0004] On the other hand, existing portable inverter power supplies have deficiencies in heat dissipation protection and connection stability. During long-term operation, due to the heat generated by internal electronic components, if the heat dissipation measures are improper, it is easy to cause the power supply temperature to be too high, which in turn affects the performance and lifespan of the power supply. At the same time, the connection structures of some inverter power supplies are not firm enough, and problems such as loose connection and short circuit are likely to occur when used in mobile or complex environments, affecting the stability and safety of power transmission. For example, in outdoor emergency rescue scenarios, the inverter power supply may be affected by factors such as vibration and humidity. If the connection structure is unreliable, it may lead to power supply interruption and delay rescue work. Summary of the Invention

Specific Embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the attached Figure 1 -attached Figure 8 , the embodiments of the present invention provide a three-in-one adaptive portable inverter power supply, including a power supply main body 1. One side of the outer wall of the power supply main body 1 is provided with a connection structure, an inverter control structure, a voltage and current detection and display structure, a heat dissipation and protection structure, and an output structure for connecting to an external power supply. The connection structure includes positive and negative terminals 2. The inverter control structure is used to control the inverter process.

The heat dissipation and protection structure is used to ensure the safe operation of the power supply. The output structure is used to output the inverted power; The outer wall of the positive and negative terminals 2 is threadedly connected with a sleeve 3, and a tight cover sheath 4 is arranged on the outer wall of the sleeve 3; Specifically, through the threaded connection between the sleeve 3 and the positive and negative terminals 2, the connection part can be tightened to prevent virtual connection caused by loosening. The tight cover sheath 4 further covers the outer wall of the sleeve 3 to form protection, avoiding short circuits caused by external environmental factors such as moisture and foreign object contact, and ensuring the stability and safety of the power supply connection.

[0023] The inverter control structure can automatically adapt to the discharge of three battery systems with voltages of DC48V, 110V, and 220V. Specifically, the inverter control structure can automatically adapt to the discharge of three battery systems with voltages of DC48V, 110V, and 220V. When connecting to batteries with different voltages, the intelligent detection circuit inside the inverter control structure will real-time sense the magnitude of the input voltage. Through pre-set programs and algorithms, it will automatically adjust the working parameters of the inverter circuit, such as frequency and duty cycle, so that the inverter process can adapt to batteries with different voltages, achieve effective control of their discharge, activate the batteries at the same time, extend their service life, and ensure the stable operation of the three DC system devices.

[0024] The heat dissipation and protection structure includes a fan heat dissipation component and a stainless steel shell 5. The fan heat dissipation component is set with its plane facing upwards and has a high-temperature self-start function. The stainless steel shell 5 is arranged on the outer wall of the power supply main body 1. Specifically, the heat dissipation and protection structure includes a fan heat dissipation component and a stainless steel shell 5. The fan heat dissipation component is set with its plane facing upwards and has a high-temperature self-start function. The stainless steel shell 5 is arranged on the outer wall of the power supply main body 1. During the operation of the power supply, internal electronic components will generate heat. When the temperature sensor detects that the temperature inside the power supply main body 1 rises to a certain threshold, the fan heat dissipation component will automatically start. The upward-facing plane setting is conducive to the natural rise of hot air, cooperating with the fan to accelerate air flow and quickly dissipate the heat. The stainless steel shell 5 can not only physically protect the electronic components inside the power supply main body 1, preventing damage to the components caused by external collisions, squeezes, etc., but also, due to its good heat dissipation performance, assist in conducting the internal heat out, ensuring the stable operation of the power supply within a safe temperature range.

[0025] The voltage and current detection and display structure includes a DC voltmeter 6. The DC voltmeter 6 is arranged on the left side of the surface of the power supply main body 1 and is used to real-time detect the DC input voltage of 48V - 220V. An output AC meter 7 is arranged on the right side of the surface of the power supply main body 1 and is used to real-time detect the output voltage and current. The voltage and current detection and display structure also includes an indicator light 9. The indicator light 9 includes a green light 901, a first red light 902, and a second red light 903. The green light 901 is used for working detection, the first red light 902 is used for fault detection, and the second red light 903 is used to indicate shutdown. The indicator light 9 flashing once continuously indicates under-voltage input, flashing twice continuously indicates over-voltage input, flashing three times continuously indicates program failure, flashing four times continuously indicates overload short circuit, flashing five times continuously indicates over-temperature protection, and the indicator light 9 staying on constantly indicates equipment failure shutdown. Specifically, the voltage and current detection and display structure includes a DC voltmeter 6, which is arranged on the left side of the surface of the power supply main body 1 and is used to detect the input DC voltage of 48V - 220V in real time. An output AC meter 7 is arranged on the right side of the surface of the power supply main body 1, which is used to detect the output voltage and current in real time. The DC voltmeter 6 is connected to the DC input line of the power supply to obtain the real-time DC voltage signal and convert it into an intuitive digital or pointer display, enabling the user to understand the voltage situation of the input power supply at any time to determine whether the power input is normal. The output AC meter 7, through specific current transformers and voltage sensors, collects the AC voltage and current signals output after inversion in real time, and after processing, displays them on the meter, providing the user with output power parameters to facilitate reasonable connection of load devices according to actual needs. The voltage and current detection and display structure also includes an indicator light 9, which includes a green light 901, a red light one 902, and a red light two 903. The green light 901 is used for working detection, the red light one 902 is used for fault detection, and the red light two 903 is used to indicate shutdown. The indicator light 9 flashing once continuously indicates under-voltage input, flashing twice continuously indicates over-voltage input, flashing three times continuously indicates program failure, flashing four times continuously indicates overload short circuit, flashing five times continuously indicates over-temperature protection, and the indicator light 9 staying on constantly indicates equipment failure shutdown. When the power supply is working normally, the green light 901 lights up, indicating that the power supply is in a normal operating state. Once an abnormal situation occurs, the corresponding indicator light will emit an alarm in a specific flashing manner. For example, when the input voltage is lower than the normal range, the indicator light 9 will flash once continuously, prompting the user that the input is under-voltage, which may affect the normal operation of the power supply; if it flashes twice continuously, it means that the input voltage is too high, which may damage the internal components of the power supply. When it is detected that an error occurs in the program operation, such as abnormal control algorithm or data transmission error, the indicator light 9 flashes three times continuously. If an overload short circuit occurs, that is, the load current is too large or a short circuit fault occurs in the circuit, the indicator light 9 flashes four times continuously, reminding the user to check for faults in time to avoid equipment damage. When the internal temperature of the power supply is too high and the over-temperature protection mechanism is triggered, the indicator light 9 flashes five times continuously. If the indicator light 9 stays on constantly, it indicates that the equipment has a serious fault and has automatically shut down, and a comprehensive overhaul is required.

[0026] The inversion control structure includes an inversion switch 8, which is installed in the middle of one side of the outer wall of the power supply main body 1. Pressing the inversion switch 8 to the left turns it off, and pressing it to the right turns it on. It needs to be turned on after the DC connection is completed. Specifically, the inverter switch 8 is turned off when pressed to the left and turned on when pressed to the right. It needs to be turned on after the DC connection is completed. When the user correctly connects the external DC power supply to the power supply main body 1 through the connection structure, ensure that the connection is stable and there are no abnormal conditions. At this time, the inverter switch 8 can be operated. Press the inverter switch 8 to the right to connect the inverter circuit and start the inversion process, converting the DC power supply into an AC power supply output. Press the inverter switch 8 to the left to cut off the inverter circuit, stop the inverter output, and at the same time, the battery is powered off and enters the shutdown state. Such a design allows the user to flexibly control the inversion function of the power supply according to actual needs, turn off the switch when the inversion function is not in use, and avoid unnecessary energy consumption and potential risks.

[0027] The output structure includes an AC output terminal 10 and a DC input terminal 11. The left red one in the AC output terminal 10 is the live wire, the middle black one is the neutral wire, and the right black one is the ground wire. The left red one in the DC input terminal 11 is the positive pole of the storage battery, and the right black one is the negative pole of the storage battery. Specifically, the output structure includes an AC output terminal 10 and a DC input terminal 11. The left red one in the AC output terminal 10 is the live wire, the middle black one is the neutral wire, and the right black one is the ground wire. The left red one in the DC input terminal 11 is the positive pole of the storage battery, and the right black one is the negative pole of the storage battery. The external DC power supply is connected to the power supply main body 1 through the DC input terminal 11. The red positive terminal is connected to the positive pole of the storage battery, and the black negative terminal is connected to the negative pole of the storage battery to ensure that the current can flow smoothly into the power supply main body 1 for subsequent inversion processing. The inverted AC power supply is output through the AC output terminal 10. The left red live wire serves as the energized conductor to provide electrical energy for the load; the middle black neutral wire is used to form a loop to enable the current to flow normally; the right black ground wire is mainly used for safety protection. When a leakage or other fault occurs in the device, the current is introduced into the ground to avoid electric shock accidents and ensure the personal safety of the user and the normal operation of the device.

[0028] The connection structure includes a terminal block 12, and the terminal block 12 is an M6 bolt. The power of the power supply main body 1 is 48V 6000VA, 110V 8000VA, 220V 8000VA; the input is adaptive DC48V + 110V + 220V, and the output is 220VAC 50HZ L + N + PE, with the communication function of detecting and displaying the DC input voltage and detecting and displaying the AC inverter output voltage and current. Specifically, the connection structure includes a terminal 12, and the terminal 12 is an M6 bolt. Using an M6 bolt as the terminal 12 can provide sufficient fastening force to ensure a firm and reliable connection between the external wire and the power supply main body 1. When connecting the wire, tighten the M6 bolt with a 10# wrench to make the wire in close contact with the terminal, reduce resistance, lower the risk of heat generation, and ensure the stability of current transmission. After the connection is completed, put on the corresponding sheath to prevent the bolt from being lost. At the same time, it further enhances the protection performance of the connection part, avoiding connection loosening or short circuit caused by factors such as external force pulling and moisture. The power of the power supply main body 1 is 48V 6000VA, 110V 8000VA, 220V 8000VA; the input is adaptive DC48V + 110V + 220V, and the output is 220VAC 50HZ L + N + PE, with the communication function of detecting and displaying the DC input voltage and the AC inverter output voltage and current. This means that the power supply can adapt to DC inputs of different voltage levels and automatically adjust the working mode according to the input DC voltage to match the corresponding power output. For example, when the input is DC48V, the power supply main body 1 operates at a power of 48V 6000VA; when the input is DC110V or DC220V, it operates at powers of 110V 8000VA and 220V 8000VA respectively, and outputs a stable 220VAC, 50Hz AC power supply through three wires of L (live wire), N (neutral wire), and PE (ground wire) to meet the power consumption needs of various standard AC loads. At the same time, the communication function of the power supply enables the real-time data of the DC input voltage and the AC inverter output voltage and current to be detected and displayed, facilitating the user to monitor the operating state of the power supply in real time, promptly discover potential problems, and ensure that the power supply can operate stably and efficiently under various working conditions.

[0029] Working principle: When in use, first connect to an external power supply through the connection structure. The positive and negative terminals 2 on the connection structure are threadedly connected to the sleeve 3. A tight cover sheath 4 is provided on the outer wall of the sleeve 3. The connection part is firmly connected through the sleeve 3 to prevent loose connection. The tight cover sheath 4 avoids short circuits caused by moisture, foreign object contact, etc., ensuring stable and safe connection. The terminal 12 is an M6 bolt. After tightening with a 10# wrench, a sheath is put on to reduce resistance and the risk of overheating, ensuring stable current transmission. After connecting the DC power supply, the inverter control structure comes into play. Its internal intelligent detection circuit continuously senses the input voltage. When connecting to three battery systems of DC48V, 110V, and 220V, it automatically adjusts working parameters such as the frequency and duty cycle of the inverter circuit, effectively controlling the discharge of batteries with different voltages, activating and extending the service life of the batteries, ensuring the stable operation of DC system equipment. By operating the inverter switch 8 located in the middle on one side of the outer wall of the power supply body 1, press it to the right to turn on the inverter circuit, converting the DC power supply into an AC power supply output. Press it to the left to cut off the inverter circuit, stop the output and cut off the power supply of the battery. During operation, the heat dissipation and protection structure ensures the safety of the power supply. When the temperature sensor detects that the temperature inside the power supply body 1 rises to a certain threshold, the fan heat dissipation component with the high-temperature self-start function and set with the plane facing up starts, accelerating heat dissipation in cooperation with the principle of natural upward movement of hot air. The stainless steel shell 5 also assists in heat conduction while preventing internal components from being damaged by external collision and extrusion. The voltage and current detection and display structure real-time feedbacks the power supply status. The DC voltmeter 6 detects the DC input voltage of 48V - 220V, and the output AC meter 7 detects the output voltage and current. The indicator light 9 indicates the working status through different flashing modes. When the green light 901 is on, it means normal operation. Flashing once continuously indicates under-voltage input, flashing twice continuously indicates over-voltage input, flashing three times continuously indicates program failure, flashing four times continuously indicates overload short circuit, flashing five times continuously indicates over-temperature protection, and staying on continuously indicates equipment failure shutdown. The power of the power supply body 1 is automatically matched according to the input voltage. The input is adaptive DC48V + 110V + 220V, and the corresponding powers are 48V 6000VA, 110V 8000VA, and 220V 8000VA respectively. After inversion, an AC power supply of 220VAC and 50Hz is output, and is output through the AC output terminal 10. Among them, the left red live wire supplies power, the middle black neutral wire forms a loop, and the right black ground wire is used for safety protection. The power supply also has the communication function of detecting and displaying the DC input voltage and detecting and displaying the AC inverter output voltage and current, facilitating users to real-time monitor the operation status of the power supply and ensuring its stable and efficient operation.
