Mobile electrical power box

Abstract

The invention relates to a mobile power box, which has the advantages of independent use, safety and convenience. The mobile power box comprises a box body; the box body is provided with a winding roller inside in a relative rotation way; a control panel is positioned above the winding roller; a conducting wire is wound onto the winding roller; one end of the winding roller is connected with a crank; and the crank is positioned outside the box body. One side wall in the box body is fixedly connected with a rotary supporting seat, and the side wall of the box body opposite to the rotary supporting seat is provided with a shaft passing hole; one end of the winding roller is provided with a rotary supporting shaft, the other end of the winding roller is provided with a rotary hole passing shaft, the rotary supporting shaft is positioned in the rotary supporting seat, the rotary hole passing shaft passes through the shaft passing hole, and the free end of the rotary hole passing shaft is connected with the crank; and the side wall of the box body is provided with a conducting wire inlet and outlet which corresponds to the winding roller, and the conducting wire passes through the conducting wire inlet and outlet. The mobile power box belongs to a 220V power safety control device, and is suitable for various users or enterprises using temporary power supplies.

Description

technical field [0001] The invention relates to a temporary power supply box, in particular to a mobile power supply box. Background technique [0002] At present, there are two kinds of temporary power boxes used in the market, namely the maintenance power control box and the power panel. The design of the maintenance power control box has been relatively reasonable and diversified. The insulating control panel is designed with incoming line terminal buttons, outgoing line terminal buttons, grounding terminal buttons, leakage protectors, isolation switches, power indicator lights, power sockets, etc. on the surface of the insulating board control surface. A serious shortcoming is that the maintenance power supply control box needs to be used in conjunction with additional wires. It is only a control box and cannot be used independently, which brings inconvenience to carrying and use; various power supply panels are designed Most of them are composed of wires, leakage prote...

[0002] At present, there are two kinds of temporary power boxes used in the market, namely the maintenance power control box and the power panel. The design of the maintenance power control box has been relatively reasonable and diversified. The insulating control panel is designed with incoming line terminal buttons, outgoing line terminal buttons, grounding terminal buttons, leakage protectors, isolation switches, power indicator lights, power sockets, etc. on the surface of the insulating board control surface. A serious shortcoming is that the maintenance power supply control box needs to be used in conjunction with additional wires. It is only a control box and cannot be used independently, which brings inconvenience to carrying and use; various power supply panels are designed Most of them are composed of wires, leakage protectors and sockets. The wires are spirally wound on iron winding rollers, and both sides are closed with iron guards to ensure that the wires do not loosen to both sides. Finally, this The cable reel is fixed and suspended with a core-through iron frame to facilitate the winding of the wires in and out. Its disadvantage is that the power control design is relatively simple, especially there is no power control knife switch, and the power supply is only disconnected by the leakage protector without obvious disconnection. Point, if the leakage protector is damaged, it is impossible to ensure safe separation when the power supply needs to be separated, and the internal conduction cannot be seen from the outside, which can easily cause physical injury to personnel and is unsafe to use
