Multifunctional portable charging device

Abstract

The invention discloses a multifunctional portable charging device which comprises a power box, a battery module, an inverter, an alternating and direct voltage table and a safety device. The inverteris installed in a power box and used for converting stable direct voltages generated by the battery module into controllable alternating voltages. The alternating and direct voltage table is used fordisplaying the real-time current and voltage value of the charging device. The safety device is arranged on an input panel of the power box through a fastening rotary knob, connected to the battery module in series through a wire and used for preventing the short-circuit of an electrical circuit and the power burning-out caused by too large currents. By means of the multifunctional portable charging device, the problems that a cannon-carried storage battery is not stable in performance, charging and maintenance are difficult, the function is simplex and elements are not complete are effectively solved; according to the charging device, a maintenance-free storage battery pack is adopted as the power supply, the high-power high-conversion-rate inverter serves as the core, alternating voltages meeting different load requirements of cannons can be output, cannon shooting training can be continuously conducted, and electric appliances for external maintenance guarantee are powered under the night battle illumination and field battle conditions.

Description

technical field [0001] The invention relates to the technical field of electric manufacturing, in particular to a multifunctional portable charging device. Background technique [0002] It is generally necessary to use batteries on artillery, which can be used not only as the lighting power supply of the artillery, but also as the firing and starting power supply of the artillery. In order to enable the artillery to successfully complete long-term shooting combat tasks or daily teaching and training tasks under adverse weather conditions or night training, when lighting fixtures, electric shock devices, and electric bomb supply devices continue to consume electric energy, in addition to certain requirements for battery capacity In addition, there are certain requirements for voltage stability, wide-range adjustability of voltage and current, and flexibility of AC-DC conversion. [0003] As an important part of the artillery power supply system, the battery plays a vital rol...

AI Technical Summary

Problems solved by technology

When organizing live ammunition shooting, there will often be a fully charged battery that has just been installed. After organizing half a day of shooting training, the battery may have insufficient power and insufficient firing voltage, resulting in failure of the artillery electric shock device and failure to fire normally.

Sometimes the voltage measured by a multimeter shows that it is fully charged, but the cannon still cannot be fired after the connection line is connected to the cannon, and the battery is in a virtual state.

[0005] (2) Difficulty in charging and maintenance

When training in the field or when the mains power cannot be connected, the charging equipment cannot be carried or used. To charge the battery equipped with the gun, it must be connected to a special charging pile to perform the charging operation.

[0006] (3) Single function and incomplete elements

One is that there is no circuit safety device. When the firing circuit of the artillery has a short-circuit fault, the battery is very likely to burn out.

The second is that the gun battery is not designed with a power display device, which cannot be used to visually display whether the power is in a state of power shortage or undervoltage in a timely manner.
