Description

Technical Field

[0001] The invention relates to the technical field of emergency power supply boxes, in particular to an intelligent emergency power supply quick access box. Background Art

[0002] The emergency power supply is composed of a charger, inverter, battery, isolation transformer, switch and other devices. It is an emergency power supply that converts DC power into AC power. In various fields such as communication, power supply and automatic control, emergency power supply boxes are needed to install electronic and electrical equipment and components.

[0003] Currently, existing power boxes can perform current rectification, frequency conversion, and inversion. Once the AC mains fails, the high-frequency switching rectifier power supply must rely on its backup battery pack to maintain power to the DC load. For example, the invention with authorization announcement number CN207218358U discloses a towable mobile power supply, which includes a box unit, which contains a working unit and an energy storage unit. The box unit consists of a box body and a cover plate sealed to the box body. Casters and a pull rod are respectively provided at both ends of the box body. The user can pull the box body to move it.

[0004] The energy storage unit includes a battery, and the housing is equipped with a display screen for displaying battery status, a charging interface, and output pins. The working unit includes a charging safety device, a rectifier, an adapter, a discharge safety device, and an output control device. The adapter is used to connect the battery's charging and discharging interfaces. The adapter's charging end, charging safety device, rectifier, and charging interface are connected in sequence; the adapter's output end, discharge safety device, output control device, and output pins are connected in sequence, and the output control device is also connected to the display screen. During charging, an external power source is connected to the charging interface, and after passing through the charging safety device, it is converted into DC power by the rectifier to charge the battery. The charging safety device will disconnect if the charging current is too high. During discharging, the output is output to the output pin through the adapter, discharge safety device, and output control device. The discharge safety device will disconnect in the event of a short circuit.

[0005] The output interface of the existing emergency power box is directly fixedly installed inside the power box, which is not conducive to installation and maintenance. In addition, since the output interface of the existing emergency power box is directly exposed to the air, it is unsafe when used on rainy days. Summary of the Invention

[0006] In response to the above-mentioned technical problems, the present technical solution provides an intelligent emergency power supply quick access box. Through the integrated mounting plate and output interface, when assembling the power box, you only need to use screws to quickly connect and fix the mounting plate and the fixing plate, which greatly improves the installation efficiency; all output interfaces can be quickly disassembled and assembled as a whole, which is convenient for inspection and maintenance of the interior of the power box; and the setting of the telescopic protective tube and cover plate can protect the output interface from rain erosion in rainy weather; it can effectively solve the above-mentioned problems.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An intelligent emergency power supply quick access box includes a box body and a box door installed on one side of the box body; a fixing plate is installed inside the box body, a mounting plate is installed in the middle of the fixing plate, and a plurality of output interfaces are integrally provided on the mounting plate; the plurality of output interfaces are respectively electrically connected to the power supply inside the box body; the output interfaces are plug-inly installed with output connectors, and are electrically connected to the output connectors to output power to the outside world.

[0009] The existing emergency power supply box directly fixes the output interface inside the power supply box, which is not conducive to installation and maintenance. In this solution, the mounting plate is integrated with the output interface when leaving the factory. When assembling the power box, you only need to use screws to quickly connect and fix the mounting plate and the fixing plate, which greatly improves the installation efficiency and enables all output interfaces to be quickly disassembled and assembled as a whole, making it easy to inspect and maintain the inside of the power box.

[0010] Furthermore, a protective cover is rotatably installed above the output interface using a rotating shaft. When the output interface is not in use, the protective cover rotates to cover the output interface, thereby protecting the output interface.

[0011] Furthermore, a temperature sensor is installed on one side of the output interface, and the temperature sensor is fixedly connected to the mounting plate. The temperature sensor can measure the temperature of the connection between the output interface and the output connector in real time. The temperature sensor is connected to the external control system signal. A three-phase electricity meter is fixedly installed on the side of the mounting plate away from the output connector. The three-phase electricity meter is electrically connected to the output interface, and the three-phase electricity meter is connected to the external control system using a 5G network signal. Management personnel can monitor the current, voltage, power, and interface temperature of the output interface in real time through the background management equipment, thereby realizing remote intelligent monitoring of the power access box.

[0012] Furthermore, a ring groove is opened on the edge of the output interface, and a telescopic protective tube is installed inside the ring groove. The innermost circle of the telescopic protective tube is the terminal cylinder. The telescopic protective tube can protect the output interface from rain erosion in rainy weather and avoid the occurrence of short circuit.

[0013] Furthermore, a plastic film sleeve is installed at one end of the terminal cylinder away from the output interface, and the plastic film sleeve can cover the output connector, further enhancing the protection performance of the power box against rain.

[0014] Furthermore, the plastic film sleeve is a wrinkled plastic film sleeve, and an elastic rubber ring is provided at the opening of one end of the plastic film sleeve away from the terminal cylinder. The elastic rubber ring can be restrained at the end of the output connector, so that the plastic film sleeve is not affected by wind and will not be blown away by the wind, thereby enhancing the stability of the plastic film sleeve in protecting the output connector and output interface.

[0015] Furthermore, the length of the terminal cylinder is greater than the length of a single telescopic cylinder in the telescopic protective cylinder, and a limiting ring is fixedly provided on the outer wall of the terminal cylinder. When the plastic film sleeve is not in use, the elastic rubber ring is stretched and expanded, and the elastic rubber ring is pulled toward the limiting ring and sleeved on the side of the limiting ring close to the output interface, so that the opening of the plastic film sleeve remains open, which facilitates the access operation of the output connector.

[0016] Furthermore, a fixing ring is slidably embedded in the inner wall of the terminal cylinder away from the output interface, and the end of the plastic film sleeve away from the elastic rubber ring is clamped between the outer wall of the fixing ring and the inner wall of the terminal cylinder. The fixing ring is used to fix the end of the plastic film sleeve, which is convenient for quick replacement of the plastic film sleeve when it is damaged, making the installation of the plastic film sleeve quick and convenient.

[0017] Furthermore, the elastic constriction rubber ring also includes a rubber ring fixing component, and the rubber ring fixing component includes a thermal connection column, a sleeve ring, and a heating wire installation groove. The sleeve ring is sleeved on the side wall of the thermal connection column, and a heating wire installation groove is opened on the inner wall of the sleeve ring. A heating wire is installed inside the heating wire installation groove, and a heat-conducting baffle is fixedly installed at the opening of the heating wire installation groove. A battery is installed inside the thermal connection column, and a circuit breaker is installed on the side wall of the thermal connection column. The circuit breaker, the heating wire, and the battery are connected in series with wires, and the plastic film sleeve is passed through the inner ring of the elastic constriction rubber ring away from the fixing ring, and then folded toward the outer ring so that the elastic constriction rubber ring is covered in the plastic film sleeve, and then the plastic film sleeve covered with the elastic constriction rubber ring is sleeved on the thermal connection column. In the gap between the connecting post and the sleeve ring, the heating wire is started by the circuit breaker, and then the heat-conducting partition conducts heat to heat the area of ​​the plastic film sleeve covered with the elastic cuff rubber ring. The plastic film sleeve and the elastic cuff rubber ring are hot-fused into one, so that the use of the plastic film sleeve and the elastic cuff rubber ring is not limited to the plastic film sleeve and the elastic cuff rubber ring that are integrated at the factory. As long as the plastic film is open at both ends, the rubber ring fixing component can be used to connect and fix it with the elastic cuff rubber ring, which expands the range of material choices for the plastic film sleeve when used and improves the flexibility of the plastic film sleeve. When there is no finished plastic film sleeve and elastic cuff rubber ring connector or the plastic film sleeve and the elastic cuff rubber ring are broken and detached, they can be made or reconnected with materials by themselves.

[0018] Furthermore, a connecting block is slidably installed on the side wall of the heat-jointing column by using a sliding rail groove, and the side wall of the connecting block is connected and fixed to the sleeve ring. The connecting block and the sliding rail groove can be used to drive the sleeve ring away from or close to the elastic cuff rubber ring. First, move away from the elastic cuff rubber ring so that the plastic film sleeve covered with the elastic cuff rubber ring can be quickly sleeved on the heat-jointing column. After the sleeve is completed, the sleeve ring is slid and reset to perform the heating operation, thereby improving the processing efficiency of the connection between the plastic film sleeve and the elastic cuff rubber ring and making the operation convenient.

[0019] Furthermore, a handle is fixedly mounted on one end of the thermal connection column, and the surface of the handle is provided with anti-slip grooves, so that the handle is easier to operate when held in hand.

[0044] The plastic film sleeve 301 is a wrinkled plastic film sleeve 301. An elastic rubber ring 401 is provided at the opening of one end of the plastic film sleeve 301 away from the terminal cylinder 203. The elastic rubber ring 401 can be restrained at the end of the output connector 107, so that the plastic film sleeve 301 is not affected by wind and will not be blown away by the wind, thereby enhancing the stability of the plastic film sleeve 301 in protecting the output connector 107 and the output interface 105.

[0045] The length of the terminal cylinder 203 is greater than the length of a single telescopic cylinder in the telescopic protective cylinder 202. A limiting ring 501 is fixedly sleeved on the outer wall of the terminal cylinder 203. When the plastic film sleeve 301 is not in use, the elastic rubber ring 401 is stretched and expanded, and the elastic rubber ring 401 is pulled toward the limiting ring 501 and sleeved on the side of the limiting ring 501 close to the output interface 105, so that the opening of the plastic film sleeve 301 remains open, which facilitates the access operation of the output connector 107.
