Abstract
The utility model discloses an anti-explosion lamp which comprises a lamp body, a light source disposed in the lamp body, and an anti-explosion shell covering the light source in a sealed manner. The air pressure of the anti-explosion shell is higher or lower end the atmospheric pressure of outside the shell. An air pressure sensor sensing the air pressure difference of the inside and the outside of the anti-explosion shell in real time is disposed on the lamp body. The air pressure sensor is connected with an alarming device. By the anti-explosion high in safety, whether the lamp is damaged or not can be monitored in real time.
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 generally consists 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 gas in flameproof enclosure and the imflammable gas outside flameproof enclosure or dust are mutually isolated, thereby extraneous imflammable gas or dust can not enter the inner generation of avoiding blast of flameproof enclosure.Yet, 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 or dust will enter flameproof enclosure inside, are easy to produce blast after bright light.
Summary of the invention
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: a kind of 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, gas pressure in described flameproof enclosure is higher or lower than the atmospheric pressure outside described flameproof enclosure, the poor gas pressure sensor of the described flameproof enclosure inner and outer air pressure of real-time induction is installed on described lamp body, and this gas pressure sensor is connected with an alarm.
As preferably, the gas pressure in described flameproof enclosure is than the high 2～50kpa of the atmospheric pressure outside flameproof enclosure.
As preferably, the gas pressure in described flameproof enclosure is than the low 2～50kpa of the atmospheric pressure outside flameproof enclosure.
As preferably, described alarm is audible-visual annunciator.
Described light emitting source, for being LED light source, can be also the various light sources such as golden halogen light source.
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 so, finally making the inside and outside gas pressure difference of flameproof enclosure is zero, the gas pressure sensor being arranged on lamp body senses that the inside and outside gas pressure difference of flameproof enclosure has occurred after variation, 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, there is very high security.
Accompanying drawing explanation
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-gas pressure sensor.
The specific embodiment
Embodiment: as shown in Figure 1, this explosion-proof lamp that the present embodiment provides, the light emitting source 2 and the seal closure that comprise 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 light source, golden halogen light emitting source.
The key improvements of the present embodiment is: the gas pressure in described flameproof enclosure 3 is higher than the atmospheric pressure outside (or lower than) described flameproof enclosure 3, the poor gas pressure sensor 4 of described flameproof enclosure 3 inner and outer air pressures of real-time induction is installed on described lamp body 1, and this gas pressure sensor 4 is connected with an alarm (not shown in FIG.).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 gas pressure sensor 4.
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, finally making flameproof enclosure 3 inside and outside gas pressure difference is zero, the gas pressure sensor 4 being arranged on lamp body 1 senses that flameproof enclosure 3 inside and outside gas pressure difference have occurred after variation, 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.
Generally, the gas pressure in flameproof enclosure 3 is more best than the atmospheric pressure outside flameproof enclosure 3 high (or low) 2～50kpa.
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 of 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.
