Abstract

The utility model relates to a portable intrinsic safety power supply for coal mines. The power supply mainly consists of a nickel hydrogen battery box, a junction box, a nickel hydrogen battery, a slide insertion assembly box, a cable insertion socket, a circuit board, a girdle box and an insulator. Power is charged and stored by the nickel hydrogen charging battery, controlled, protected, managed and detected by the circuit board, and finally output by two channels for apparatus use. The intrinsic safety power supply has the advantage of advanced and reasonable design, compact structure, small volume, portability, good insulation, broad application range, capability of outputting +5V DC power through two channels, capability of being used for miniature illumination apparatuses, high safety, stability and reliability and convenient insertion use. The utility model provides an ideal miniature portable intrinsic safety power supply for coal mines. The power supply can also be used for ground or field work.

Description

A kind of portable intrinsic safety power supply for coal mine

Technical field

The utility model relates to a kind of portable intrinsic safety power supply for coal mine, belongs to storage battery power supply apparatus technology under the coal mine.

Background technology

Along with the precise electronic technology obtains generally using widely under coal mine, various hand-hold types, portable electronic instrument and meter are because advantage such as lightly flexible, workable, more and more receive an acclaim and pay attention to, but mostly need external power source, owing to be that adverse circumstances are used under coal mine, this just needs a kind of portable accumulation electrical source with performances such as waterproof, protection against the tide, antistatics, makes power supply have essential safety, i.e. intrinsic safety electric source.

Summary of the invention

Goal of the invention

Goal of the invention of the present utility model is exactly at disadvantages of background technology, designs a kind of explosion-proof type essential safety power supply, adopts big capacity Ni-MH battery, memoryless charging, and technology such as over-voltage over-current protection are to improve fail safe, the stability of colliery down-hole power.

Technical scheme

The utility model primary structure is made up of: battery case, terminal box, sliding connector assembly box, cable combination hub, combination hub, waistband box, Ni-MH battery, circuit board, insulator; On the top of battery case 1 is terminal box 2, is sliding connector assembly box 3 on the top of terminal box 2, and the right part of sliding connector assembly box 3 is plug receptacle 7 and tie cable 8, cable 8 right part tie cable combination hubs 4; Terminal box 2 right parts are plug receptacle 5; The front portion of battery case 1 is a waistband box 6, and battery case 1 inside is Ni-MH battery 10, and Ni-MH battery 10 outsides are circuit board 11 by insulator 9 environmental sealings on insulator 9 tops, and circuit board 11 tops cover sealing by insulator 12; Be sliding connector assembly 13 in the sliding connector assembly box 3; In the cable combination hub 4 is connector assembly 14.

Described circuit board 11; form whole control circuit by Ni-MH battery group IC circuit 1, charge-discharge control circuit IC2, protective circuit IC3, constant voltage circuit IC4, IC5, protection testing circuit IC6, protection testing circuit IC7, output circuit IC8, IC9, connect by lead between each parallel circuit.

Beneficial effect

The utility model is compared with background technology has tangible advance; it is the actual conditions according to the used power supply of electronic instruments of adverse circumstances use under the coal mine; a kind of portable essential safety power supply of design; adopt the nickel-hydrogen chargeable cell charging to store; control through circuit board; protection; management; detect; after two-way output; use for instrument and meter; this power supply advanced design; rationally; compact conformation; volume is little; be easy to carry; good insulating; wide accommodation; exportable two-way 5V constant-voltage DC source; can use for the miniature instrument instrument, safety and stability is reliable, patches easy to use; be the small portable intrinsic safety accumulation electrical source that uses under the very good coal mine, this power supply also can be on ground or field work use.
