Abstract

The utility model relates to an explosion proof multi-function fluorescent lamp, which is suitable for the uses in the underground working face of coal mine, tunnels, etc. The switching elements of the utility model is composed of a controlling switch, an interlocking device, and a thermo sensitive element to control an H-shaped florescent lamp. The utility model has the advantages of simple structure and convenient maintenance. When a lamp tube needs to be changed, the main switches and the subsidiary switches can not be stopped. The time of changing a lamp is only 3-5 minutes, the work efficiency can be enhanced, and the safety can be provided. For instance, if a lamp tube is broken, the electrical source of a working chamber can be automatically cut, and the unsafe factors can be eliminated. The utility model is an ideal lighting fixture used in the underground working surface of a coal mine and a tunnel.

Description

Explosion-proof Multi-function fluorescent lamp

The utility model relates to a kind of lighting device, a kind of multifunction explosion-proof fluorescent lamp of more specifically saying so.Be applicable to that working face under the coal mine and tunnel, petrochemical industry, military installations and other have the illumination in the place of explosion risk gas.

Explosion-proof fluorescent lamp of the 20W that uses under the existing coal mine and 11WH type fluorescent lamp, complex structure, result of use is not good, if after fluorescent tube is gone bad, changes fluorescent tube and need apply for having a power failure, set up caution board or send the special messenger to keep an eye on, need stop master switch or switch-dividing, dismounting holding screw and accessory can be changed fluorescent tube, not only influence area illumination, and inefficiency, changing a fluorescent tube approximately needs about 50 minutes.In addition, above-mentioned two kinds of light fixtures do not have temperature control equipment, as surpassing setting because of certain accident causes temperature, might cause static to take place or other unsafe factor.During again just like translucent cover and fluorescent tube fragmentation, power supply can not cut off automatically in the working chamber, has conductor exposed extraneous, causes unsafe factor.

The purpose of this utility model is to have designed a kind of multifunction explosion-proof fluorescent lamp that can change fluorescent tube and band attemperating unit easily for the weak point that overcomes above-mentioned prior art, and when fluorescent tube was broken, the working chamber power supply was cut off automatically.

The purpose of this utility model can realize in the following manner: a kind of multifunction explosion-proof fluorescent lamp; include a housing; on the fixed head of housing inner chamber Energy-saving ballast is installed; patch bay; housing left side opening is airtight with end cap; the both sides up and down of housing are fixed a thread guide devices respectively; be mounted with gauge tap on the hole, garden in housing left side; housing is along fixing an interlock on the paper vertical direction; the two ends of net formula protective cover are connected as a body with seal cover and terminal pad respectively; its inboard translucent cover in addition; settle a fluorescent tube in the translucent cover; the bipod of fluorescent tube is inserted in the hole, garden, housing left side and links to each other with gauge tap; the other end withstands on the seal cover by the fluorescent tube fixed cap; terminal pad matches with the housing left side; block by claw; power line is received on the patch bay through a thread guide devices; two joints on the patch bay are received on the interlock with lead; an output of interlock links to each other with a joint of gauge tap through temperature-sensitive element with lead; the other end links to each other with another joint of gauge tap through ballast with lead, and the power supply on the patch bay can be guided on the next electric elements through another line apparatus.

The utlity model has following advantage: this light fixture is not only simple in structure, and easy to maintenance, the replacing fluorescent tube need not stop the master switch and the switch-dividing of circuit can be finished, and approximately changes a fluorescent tube and only needs 3～5 minutes, improved operating efficiency greatly, and safe and reliable; As the fluorescent tube fragmentation, the working chamber power supply is cut off automatically, does not have any unsafe factor and occurs, and excessive when electric current, when temperature surpassed setting, temperature-sensitive element was off status, when temperature just often, devote oneself to work again.
