Description
Technical field
The utility model relates to a kind of power-supply device, especially relates to a kind of intrinsic safety electric source that coal mine is divided into the explosion prevention function of getting everything ready that is used for, and belongs to the power-supply device technical field.
Background technology
The colliery construction safety is very important, in order to ensure the colliery construction safety, is responsible for functional department and person skilled and has taked a lot of measures.Such as the coal mine safety management system, the operation of the communication apparatus that this system can be by being arranged at ground and down-hole, clear, accurately and timely information such as down-hole workmen's quantity, position, operating time are monitored.But, have only and when the coal mine safety management system normally moves, could realize effectively monitoring, if a certain parts or module go wrong in the system, this system just can't implement normal monitoring.Power supply aspect as system, the common supply power mode of available technology adopting, this supply power mode first can't prevent self explosion-proof problem, if the curtage generation problem in next system, underground equipment is easy to produce spark, in case the generation spark, the consequence of bringing to the down-hole is hardly imaginable, and consequence is very serious.Therefore, a kind of power supply that has explosion prevention function, also can not produce spark because of the variation of system power voltage simultaneously of research and development is very necessary.
The utility model content
The purpose of this utility model is to bring unsafe shortcoming for the colliery safety management system in order to overcome in the prior art common supply power mode, and a kind of power supply inside that provides has the intrinsic safety electric source of overcurrent protection and short-circuit protection (recovering certainly) function.
The embodiment of the intrinsic safety electric source that is used for the colliery underground equipment of the present utility model is as follows:
The intrinsic safety electric source that is used for the colliery underground equipment of the present utility model, described intrinsic safety electric source is that silicon rubber waters the overall structure that envelope forms, described integrally-built intrinsic safety electric source comprises chargeable battery, described battery is connected with charging module, described battery is connected with the current limliting module by insurance module, described battery also directly is connected with the pressure limiting module, and described current limliting module and pressure limiting module connect the dc output end of intrinsic safety electric source.
Intrinsic safety electric source is the supply module of underground equipment in the coal mine downhole safety management system; it has the high request of explosion-proof performance; voltage input end is unidirectional charging end (charging process is finished aboveground); insurance module, current limliting module and pressure limiting module are formed the complete machine protective circuit of intrinsic safety electric source; the complete machine protective circuit realizes protection to battery by pressure limiting and current limliting, thereby reaches the safety of intrinsic safety electric source.
The beneficial effect that the relative prior art of the utility model has:
1, the intrinsic safety electric source that is used for the colliery underground equipment of the present utility model is the overall structure that silicon rubber waters envelope, has fire-retardant and explosion prevention function, is applicable to the underground equipment of coal mine safety management system, can guarantee the safe handling of underground equipment.
2, the intrinsic safety electric source that is used for the colliery underground equipment of the present utility model is provided with the complete machine protective circuit; promptly be provided with insurance module, current limliting module and pressure limiting module; when overcurrent and overvoltage; above-mentioned module can play current limliting and pressure limiting effect in the complete machine protective circuit; over proof electric current and voltage are transferred in the underground equipment to output, have guaranteed the safety of the underground equipment in the coal mine safety management system.
3, the intrinsic safety electric source that is used for the colliery underground equipment of the present utility model, simple in structure, easy to carry, service time is long, security performance good.
Description of drawings
Fig. 1 is the intrinsic safety electric source modular structure block diagram that is used for the colliery underground equipment of the present utility model.
Embodiment
Understand the technical solution of the utility model for one of ordinary skill in the art can be known, the existing work in conjunction with the accompanying drawings further at large illustrates:
The intrinsic safety electric source that is used for the colliery underground equipment of the present utility model; as shown in Figure 1; intrinsic safety electric source 1 waters the overall structure that envelope forms for silicon rubber; integrally-built intrinsic safety electric source 1 comprises chargeable battery 4; battery 4 is connected with charging module 3, and battery 4 is connected with current limliting module 7 by insurance module 5, and battery 4 also directly is connected with pressure limiting module 6; current limliting module and pressure limiting module connect the dc output end of intrinsic safety electric source, and insurance module 5, current limliting module 7 and pressure limiting module 6 are formed complete machine protective circuit 2.
Embodiment: as shown in Figure 1; battery 4 in the intrinsic safety electric source is a rechargeable battery; before the use; intrinsic safety electric source 1 is charged by charging module 3 on ground; guarantee the useful life of battery 4; after charging is finished; intrinsic safety electric source 1 is installed in the underground equipment of coal mine safety management system; under little electric current electric power thus supplied; can guarantee long-time power supply; insurance module in the complete machine protective circuit plays the safety effect of intrinsic safety electric source 1, and when intrinsic safety electric source 1 inside had overcurrent and overvoltage, the complete machine protective circuit had overcurrent protection and short-circuit protection (recovering certainly) function.
Intrinsic safety electric source 1 of the present utility model reaches the protection to power module by the complete machine protective circuit 2 (insurance module 5, current limliting module 7, pressure limiting module 6) that is arranged on inside modules, uses for underground equipment thereby make dc output end can export a galvanic current pressure.
