Abstract
The invention relates to a portable intrinsic safety power supply for coal mine, which mainly consists of a nickel-metal hydride battery box, a junction box, a nickel-metal hydride battery, a slip insert component box, a cable combination hub, a circuit board, a waistband box and an insulator, wherein the nickel-metal hydride battery is used for charging and storing; the circuit board is used for controlling, protecting, managing and detecting; and finally, the current is outputted through two paths to be used for instruments and meters. The intrinsic safety power supply has advanced and reasonable design, compact structure, small volume, convenient carrying, good insulativity and wide application scope, can output +5V DC power supply through the two paths, can be used for small-size lighting, instruments and meters, and is safe, stable and reliable as well as convenient for connecting and plugging, thus being an ideal portable intrinsic safety energy-storing power supply used under a coal mine well, and being used on the ground or for the field operation.
Description
Technical field
The present invention relates to a kind of portable intrinsic safety power supply for coal mine, belong 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
The object of the invention is exactly to 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
Primary structure of the present invention 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 present invention compares with background technology has tangible advance, and 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 nickel-hydrogen chargeable cell to charge and store, through circuit board control, protection, management, detection, after two-way output; The confession instrument and meter uses, this power supply advanced design, rationally, compact conformation, volume be little, be easy to carry, good insulating, wide accommodation; Exportable two-way 5V constant-voltage DC source; Can supply the miniature instrument instrument to use, 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.
