Description

Explosion-proof detector

Technical Field

The invention relates to the technical field of detectors, in particular to an explosion-proof detector.

Background

The laser detector is a laser instrument with high emission power density, small emission angle, strong adaptability to severe weather environment and long transmission attenuation distance, and is widely used in various fields. However, in places with severe environments, such as petrochemical industry, metallurgy and gas, potential risks are brought, so that the detector needs to be installed in an explosion-proof box, the explosion-proof box is generally sealed, the temperature in the explosion-proof box is very high after the explosion-proof box is used for a long time, and the detector is easy to break down when working in a high-temperature environment and also has a shortened service life.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides an explosion-proof detector.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an explosion-proof detector, includes outer box, and the outer box is internal through jib fixed connection inner box, is equipped with the detecting head in the inner box, and inner box one side is equipped with first opening, and first opening part is equipped with first sealed transparent sheltering from device, is equipped with the second opening outside box one side, and the second opening part is equipped with the sealed transparent sheltering from device of second.

Preferably, the first sealed transparent shielding device is a first tempered glass plate.

Preferably, the sealed transparent device that shelters from of second includes two second toughened glass boards and two clamping rings, and the outside and the inboard of box all are equipped with the mounting groove outside, are linked together through the intercommunicating pore between two mounting grooves, and two second toughened glass boards one-to-one are installed in the mounting groove and are compressed tightly fixedly through the clamping ring.

Preferably, the pressing ring is fixed to the outer case by a bolt.

Preferably, one side of the outer box body is provided with an exhaust tube.

Preferably, an air inlet pipe is arranged on one side of the inner box body, one end of the air inlet pipe penetrates through the outer box body and extends out of the outer box body, an exhaust pipe is arranged on one side of the inner box body, a spiral coil pipe is arranged in the outer box body and wound on the outer side of the inner box body, one end of the spiral coil pipe is connected with the exhaust pipe, and the other end of the spiral coil pipe penetrates through the outer box body and extends out of the outer box body.

Preferably, outer box downside fixed connection support column, support column downside fixed connection bottom plate.

The invention has the advantages that: air is exhausted from the outer box body through the exhaust tube, so that the pressure in the outer box body is smaller than the pressure of the inner box body, inert cooling gas is filled into the inner box body through the air inlet tube, the inner box body is cooled, gas exhausted from the inner box body is discharged through the spiral coil, and when the gas passes through the spiral coil, the temperature can be lowered in the outer box body, and the temperature lowering effect is further improved.

FIG. 1 is a schematic diagram of the basic structure of the present invention;

fig. 2 is an enlarged view of a portion a of fig. 1.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-2, the explosion-proof detector provided by the invention comprises an outer box 1, wherein a support column 52 is fixedly connected to the lower side of the outer box 1, and a bottom plate 5 is fixedly connected to the lower side of the support column 52. The inner box body 2 is fixedly connected with the inner box body 2 through the suspender 11 in the outer box body 1, the detecting head 3 is arranged in the inner box body 2, a first opening is arranged on one side of the inner box body 2, a first sealed transparent shielding device 21 is arranged at the first opening, and the first sealed transparent shielding device 21 is a first toughened glass plate. A second opening is arranged on one side of the outer box body 1, and a second sealed transparent shielding device is arranged at the second opening. The sealed transparent device that shelters from of second includes two second toughened glass boards 14 and two clamping rings 15, all is equipped with the mounting groove in the outside of box 1 outside with the inboard, is linked together through intercommunicating pore 13 between two mounting grooves, and two second toughened glass boards 14 one-to-one are installed in the mounting groove and are compressed tightly fixedly through clamping ring 15. The pressing ring 15 is fixed to the outer case 1 by a bolt 16. An air exhaust pipe 12 is arranged on one side of the outer box 1. Interior box 2 one side is equipped with

intake pipe

23, and 23 one end of intake pipe runs through outer box 1 and stretches out the outside of outer box 1, and interior box 2 one side is equipped with blast pipe 22, is equipped with spiral coil 4 in the outer box 1, and spiral coil 4 winds in the 2 outsides of interior box, and spiral coil 4's one end links to each other with blast pipe 22, and spiral coil 4's the other end runs through outer box 1 and stretches out the outside of outer box 1.
