Abstract
The utility model discloses an anti-explosive lamp which comprises a lamp body, a light-emitting source installed in the lamp body and a flameproof casing covering outside the light-emitting source in a sealing mode. The lamp body is provided with a flammable gas detector contained in the flameproof casing and capable of detecting flammable gas, and the flammable gas detector is electrically connected with an alarm. The anti-explosive lamp can monitor whether the lamp is damaged in real time and safety of use environment of the lamp is improved.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of explosion-proof lamp.
Background technology
Explosion-proof lamp refers to the hazardous area for imflammable gas and dust existence, can prevent imflammable gas and dust that the inner issuable electric arc of lamp, spark and high temperature ignite in surrounding environment, thereby reach the light fixture of requirement of explosion proof, as: the explosion-proof flashlight being used under the explosion-proof illuminating lamp that chemical plant is used and ore deposit.
Explosion-proof lamp is generally made up of parts such as lamp body, light emitting source and flameproof enclosures, and wherein flameproof enclosure and lamp body are sealedly and fixedly connected and seal closure is located at light emitting source outside.Under normal condition, the imflammable gas outside gas and flameproof enclosure in flameproof enclosure or dust are mutually isolated, thereby extraneous imflammable gas can not enter the inner generation of avoiding blast of flameproof enclosure.But, sometimes can be because all unexpected factors cause the sealed environment in flameproof enclosure destroyed, as: flameproof enclosure breaks, gap etc. appears in flameproof enclosure and lamp body junction, and staff can not find this problem very timely, so, extraneous imflammable gas will enter flameproof enclosure inside, is easy to produce blast after bright light.
Utility model content
The utility model object is: for the problems referred to above, provide a kind of explosion-proof lamp that can Real-Time Monitoring light fixture damages situation.
The technical solution of the utility model is: described explosion-proof lamp, the light emitting source and the seal closure that comprise lamp body, be contained in this lamp body are located at the flameproof enclosure outside described light emitting source, on described lamp body, be provided with and be contained in imflammable gas detector in described flameproof enclosure, that can survey imflammable gas, described imflammable gas detector is electrically connected with an alarm.
As preferably, described imflammable gas detector is gas detector.
As preferably, described alarm is audible-visual annunciator.
As preferably, described light emitting source is LED lamp, electricity-saving lamp or Non-polarized lamp.
The utility model has the advantages that: this explosion-proof lamp of the utility model, if the sealed environment of its flameproof enclosure inside is destroyed, the inside and outside gas of flameproof enclosure no longer mutually completely cuts off and can mutually flow, the imflammable gas of flameproof enclosure outside will enter flameproof enclosure inside like this, imflammable gas detector will detect flameproof enclosure inside entered imflammable gas and by this communication to alarm, there is again sound and light signal and remind corresponding personnel that this explosion-proof lamp damages in alarm, need repairing or change, thering is very high security.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1-lamp body, 2-light emitting source, 3-flameproof enclosure, 4-imflammable gas detector.
Detailed description of the invention
Embodiment: Fig. 1 has shown a specific embodiment of this explosion-proof lamp of the utility model, light emitting source 2 and seal closure that it comprises lamp body 1, be contained in this lamp body are located at the flameproof enclosure 3 outside described light emitting source, and wherein light emitting source 2 can adopt the various forms such as LED lamp, Non-polarized lamp or technical ability lamp.
The key improvements of the present embodiment is: on described lamp body 1, be provided with and be contained in imflammable gas detector 4 in described flameproof enclosure 3, that can survey imflammable gas (on imflammable gas detector with inductive probe), and this imflammable gas detector 4 is electrically connected with an alarm (not shown).Described alarm can adopt multiple alarm form, and in this example, this alarm is the audible-visual annunciator that can send acoustic alarm signal, visual alarm can occur again.Certainly, described alarm also can adopt other versions, such as: the computer being connected with described imflammable gas detector 4.
Under normal circumstances, in the enclosed environment of the probe of imflammable gas detector 4 in being formed by flameproof enclosure 3, extraneous imflammable gas cannot enter flameproof enclosure 3 inside, and imflammable gas detector 4 can not detect the existence of imflammable gas.If flameproof enclosure 3 self breaks, or there is gap with lamp body 1 junction in flameproof enclosure 3, and cause the sealed environment of flameproof enclosure 3 inside destroyed, the inside and outside gas of flameproof enclosure 3 no longer mutually completely cuts off and can mutually flow so, the imflammable gas of flameproof enclosure 3 outsides will enter flameproof enclosure 3 inside like this, imflammable gas detector 4 will detect flameproof enclosure 3 inside entered imflammable gas and by this communication to alarm, there is sound and light signal again and remind corresponding personnel that this explosion-proof lamp damages in alarm, needs repairing or change.
If use this explosion-proof lamp in coal mine, described imflammable gas detector 4 can adopt the gas detector that can survey gas.Certainly, if use this explosion-proof lamp in petroleum industry and chemical industry, this imflammable gas detector can adopt other versions, with the common imflammable gas in locate oil industry and chemical industry.
Certainly, above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
