Embodiment 1

[0022] Such as Figure 1-2 As shown, an LED explosion-proof lamp for underground engineering construction includes a housing 1 and a transparent lampshade 2 installed on the housing 1. An LED light source 3 is installed in the transparent lampshade 2, and a cover device is installed on the side wall of the housing 1. The protective net 4 outside the transparent lampshade 2, the protective net 4 is composed of a plurality of transparent tubes 5, and the transparent tubes 5 are hard transparent PVC tubes, which have a good protective effect and will not block the light. Filled with thermal expansion and contraction medium, the thermal expansion and contraction medium is a mixed gas of nitrogen dioxide and dinitrogen tetroxide, the balance of the mixed gas can change when the temperature changes, and the reaction equation is NO 2 ==N 2 o 4 , is a reversible reaction.

Embodiment 2

[0029] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that one of the fan blades of the fan 14 is wound with a multi-turn closed coil 17, and the side wall of the housing 1 is fixedly connected with a permanent magnetic strip 18, and the fan 14 A buzzer piece 16 is installed on the top, and the two poles of the buzzer piece 16 are respectively coupled and linked with the two ends of the closed coil 17. The winding direction of the closed coil 17 is perpendicular to the direction of the magnetic induction line of the permanent magnetic strip 18. According to the principle of electromagnetic induction, When the closed coil 17 rotates with the fan 14, it can continuously cut the magnetic field lines of the permanent magnetic strip 18 to generate an induced current.

[0030] In this embodiment, when the temperature of the lighting lamp is high, the thermal expansion and contraction medium expands rapidly, driving the fan 14 to rotate rapidly,...

Abstract

The invention belongs to the field of LED lamps, and particularly relates to an LED explosion-proof lamp for underground engineering construction, which comprises a shell and a transparent lampshade mounted on the shell, an LED light source is mounted in the transparent lampshade, a protective net covering the transparent lampshade is mounted on the side wall of the shell, and the protective net is composed of a plurality of transparent tubes. The transparent pipes are filled with heat expansion and cold contraction media, an annular box body is fixedly connected to the bottom of the shell, the multiple transparent pipes penetrate through the shell and the bottom of the annular box body and communicate with the interior of the annular box body, and a sealing ring is connected into the annular box body in a sealed and sliding mode. Two parallel racks are fixedly connected to the side wall of the sealing ring, and a horizontally-arranged rotating shaft is arranged in the shell in a rotating mode. By means of rotation of the fan and circulating and reciprocating flow of cooling liquid, a good cooling and heat dissipation effect is provided, when the temperature is too high, light canbe reflected into red light through the protective net, and the buzzing piece can give out alarm sound to give out safety warning to workers.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to an explosion-proof LED lamp for underground engineering construction. Background technique [0002] With the needs of urban development, according to the successful experience of urban construction at home and abroad, the development and utilization of urban underground space resources is the development trend of urban construction. During the construction of underground projects, lighting lamps need to be installed to provide temporary lighting. A large amount of dust or flammable gas, so it is necessary to use LED explosion-proof lights with sealing and explosion-proof performance. [0003] Most of the traditional explosion-proof lamps are equipped with closed and heavy shells to ensure their safety and explosion-proof performance. However, after working for a long time, their heat dissipation effect is poor, and the internal temperature is high, which greatly reduces the service life ...
