In addition, the explosion-proof device of the traditional lamp is integrated with the lamp, is difficult to be suitable for other lamps, and cannot be arranged on other lamps, so that other lamps have an explosion-proof function. Moreover, the explosion-proof device of the traditional lamp is difficult to disassemble, when the lamp is damaged, the explosion-proof device is disassembled to replace the lamp, and then the explosion-proof device is installed, so that the whole process is complicated and inconvenient to operate.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide an explosion-proof equipment for platform illumination lamps and lanterns, this device simple structure, simple to operate, firm reliable, strong adaptability to in the use, explosion-proof reliable can guarantee platform safety in production's needs.

The utility model provides a technical scheme that technical problem adopted does:

the utility model discloses an explosion-proof device for ocean platform lighting lamp, which comprises a lamp holder, the lamp holder comprises a sleeve, a groove is arranged at the upper part in the sleeve, a metal internal thread section is arranged on the side wall of the groove, two electric wire jacks communicated with the bottom wall of the groove are arranged at the lower part of the sleeve, a metal contact point is fixed on the bottom wall of the groove at the position of one electric wire jack, a funnel-shaped wire interface is fixed on the bottom wall of the sleeve, a heat shrink tube is fixed on the outer wall of the straight tube section of the funnel-shaped wire interface, one end of a wire internally provided with two power wires passes through the heat shrink tube and the two power wires are respectively in contact connection with the metal internal thread section and the metal contact point of the lamp holder, a plug is arranged at the other end of the wire, an external thread is arranged at the lower part of the outer wall of the sleeve, the sealing strip is wound on the external thread of the sleeve, the sleeve is in threaded connection with the internal thread on the straight pipe section of the horn-shaped base through the external thread, a bulb with a metal screw is in threaded connection with the internal thread section of the sleeve through the metal screw, a sealing ring is arranged on the horn-shaped opening edge of the horn-shaped base, the bottom edge of a transparent lampshade is tightly pressed on the sealing ring, and the horn-shaped opening edge of the horn-shaped base is fixedly connected with the bottom edge of the transparent lampshade and the sealing ring through a screw and a nut.

The utility model has the advantages that: the device has the advantages of simple structure, convenience in installation and lamp replacement, reduces the field workload, is concise in appearance, and is suitable for being used on ocean modules; the sealing belt and the sealing ring are used for sealing, so that the explosion prevention is reliable, and the safe operation of the offshore platform is ensured.

Detailed Description

The present invention will be further described with reference to the following detailed description.

The utility model discloses an explosion-proof equipment for platform illumination lamps and lanterns as shown in the attached drawing, including lamp stand 2, as shown in fig. 2, fig. 4, lamp stand 2 include sleeve 21 in the upper portion be provided with the recess the lateral wall of recess on be provided with metal internal thread section 22 to be fixed with metal contact 23 on the diapire of recess sleeve 21 the lower part open and to have two electric wire jacks that communicate with the diapire of recess, be fixed with a metal contact 23 on the recess diapire of one of them electric wire jack position department, metal internal thread section 22 and metal contact 23 be two electrically conductive metal contacts of lamp stand respectively. The lamp socket is characterized in that a funnel-shaped wire interface 9 is fixed on the bottom wall of the sleeve, a heat shrink tube is fixed on the outer wall of the straight tube section of the funnel-shaped wire interface, one end of a wire 8, provided with two power wires inside, penetrates through the heat shrink tube 9, the two power wires are respectively in contact connection with a metal internal thread section 22 and a metal contact point 23 of the lamp socket 2, a plug is installed at the other end of the wire 8, and when the wire 8 is connected with a power supply through the plug, current is transmitted to the bulb 1 to supply power.
