Description
Technical field
The utility model relates to a kind of explosion-proof lamp, especially relates to flameproof LED anti-explosion lamp.It is applicable to the places such as underworkings, chamber, concentrator station, electric substation, pump house; Also be applicable to containing in the hazardous environment such as damp or steam, and illumination use is done in various indoor and outdoor operation (industry such as electric power, metallurgy, railway, mine, harbour, municipal administration) plant area, station, venue and the place such as railway tunnel, bridges and culverts.
Background technology
LED anti-explosion lamp kind of the prior art is more, and as shown in Figure 1, its top of explosion-proof lamp the most common is the shell of spherical cap shape, and housing exterior is designed with reinforcement, and the top of shell is the female tubulose mounting bracket of band; Be connected with Transparent Parts below shell, the vertical extension of Transparent Parts is longer, and therefore Transparent Parts outside is covered with protection network.Transparent Parts internal light source generally still adopts conventional light source, as fluorescent lamp, Metal halogen lamp etc.
Assembly structure and the prior art of Transparent Parts of the present utility model and shell are different.Prior art generally adopts the upper plane of Transparent Parts to do explosion suppresion surface or does hermetically-sealed construction by plane pressure seal ring in Transparent Parts.Transparent Parts is become concordant with shelling machine, and due to the characteristic of Transparent Parts processing technology, Transparent Parts flange face cannot be accomplished smooth, and deflection is within 2mm, though manual polishing do not accomplish yet with casing explosion-proof face gap 0.2mm within.So uniformity is just difficult to ensure.
Above-mentioned explosion-proof lamp of the prior art to design by the carrying out of GB GB 3836.1-2000 and certification, do not meet the requirement of Kunming Market GB 3836.1-2010, and field of employment limitation is large, if by I class Explosion-proof Design, coal mine gas gas environment can only be used for; By II class Explosion-proof Design, other explosive gas atmosphere except coal mine gas gas can only be used for, as ethene, hydrogen etc.There is following defect in this external technical elements:
1. adopt conventional light source, light fixture optical efficiency is low, not energy-conservation.
2. mounting means is single, can not meet the need of market.
3. be with protection network, the dust of Transparent Parts surface accumulation is not easy cleaning, affects whole light effect.
4. light fixture is in rated operation always, and the light source normal phase is in operating temperature ratings state, and the service life of whole lamp is lower.
5. not there is dimming function, within 24 hours, need the place of illumination not energy-conservation for whole day.
Utility model content
It is good that the purpose of this utility model is to provide a kind of explosion-proof performance, a kind of square laneway explosion-proof lamp that use cost is lower.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of square laneway explosion-proof lamp, its main body is shell, and shell upper is fixedly connected with mounting bracket, airtightly under shell is connected with Transparent Parts, it is characterized in that: shell is made up of the upper casing connected successively from top to bottom, mesochite and lower casing; Upper shell upper portion is connected and installed support, and upper casing bottom is combined with mesochite by plane flame-proof faying face, and plane flame-proof faying face is provided with sealing ring; The left and right sides of mesochite is designed with cable interface respectively, the cable interface of side is threaded with the clamp nut of column, it is the packing ring of annular and sealing gasket that cable on the inner side and mesochite of clamp nut penetrates between mouthful sidewall, and sealing gasket and lead-in cable are tightly connected; The cable interface of opposite side is closed by plug, and plug and cable penetrate the sealing gasket being also provided with annular between mouthful sidewall; In the inner chamber of mesochite, the Position Design corresponding with lead-in cable has binding post, and the below of binding post is electrically connected with driving power; Mesochite bottom is connected with lower casing by cylindrical flameproof joint, and cylindrical flameproof joint is provided with " O " RunddichtringO; Be the installing plate of level in the middle part of lower casing inner chamber, driving power is fixing on a mounting board; Lower casing border is designed with square ring flange, and ring flange and pressing plate are bolted, ring flange be the explosion-proof composition surface of being with sealing ring with square pressing plate upper surface; Pressing plate inner edge, by the horizontal side compressing on square Transparent Parts top, is adhesive bond face between Transparent Parts peripheral side wall and pressing plate madial wall; Transparent Parts is the shape of falling truncated rectangular pyramids, is provided with the light source assembly of the shape of falling truncated rectangular pyramids in Transparent Parts inner chamber, and light source assembly side is provided with LED light source and reflector.
Above-mentioned a kind of square laneway explosion-proof lamp, it is characterized in that: in the bottom of light source assembly, intelligent dimming module is installed, intelligent dimming module is made up of microwave induced module and control circuit, be plate aerial in the middle part of microwave induced module, intelligent dimming module is connected with driving power by input-output line group; Intelligent dimming module installs rear plate antennas orthogonal downward.
Above-mentioned a kind of square laneway explosion-proof lamp, it is characterized in that: on the madial wall of pressing plate, be designed with annular shoulder, annular shoulder evenly has screw, compressing tablet is fixed on pressing plate by the screw coordinated with screw, and Transparent Parts outer rim grips by compressing tablet and pressing plate inner edge.
The left and right sides of the utility model mesochite is designed with cable interface respectively, generally, only needs the cable interface of side to connect lead-in cable, is compressed by clamp nut.Opposite side blocks with plug at ordinary times, when light fixture needs in parallel, is taken down by plug, connects shunt cable.Greatly reduce cloth electricity workload.
Because Transparent Parts adopts the shape of falling truncated rectangular pyramids, the effective rate of utilization of light can be improved on the one hand, make the light full illumination of light fixture in long and narrow tunnel, avoid waste irradiation, as shown in Figure 5, in the tunnel of same distance, the light fixture quantity used is little, reaches energy-saving effect.Transparent Parts surface area reduces greatly on the other hand, and structural strength increases, and no longer needs protection network, then add whole lamp degree of protection and reach IP66, facilitate client to rinse the dust of Transparent Parts surface long time integration in use with giant, effectively can improve the lumen utilization rate of light fixture.
Owing to having installed intelligent dimming module additional, when light fixture works at ordinary times, can two states be in: 20% brightness time entirely bright, idle during work, idlely specifically need bright how much can carrying out to arrange (from 0-100%).When there being people to come into field of illumination, light fixture is entirely bright.And underworkings major part region and most of the time are all depopulated zones, as: gallery, inclined shaft lane, electric substation, pump house etc., these light fixtures are in idle condition at ordinary times, greatly can save electric energy, directly produce economic benefit.
