Wherein upper cover inside is provided with LED interior light, for providing good visual environment for operator.
Wherein upper cover side has two gloves holes, is provided with emgloves, is convenient to both hands and enters operation in case thus.
Wherein import and export position at fiber optic cables and high resiliency silica gel is installed, the surface of contact of upper cover and base, the closed system be made up of silica gel strip is installed, can not leak by inert gas in guard box, reach the object of safe welding.
Wherein base is installed the pressure-fired voltage-regulating system be made up of inert gas steel cylinder, in guard box, pressure is greater than case external pressure, source of the gas can be provided to ensure proceeding of welding work by external interface when having micro-leakage and in case, gas is not enough.
Wherein floor installation has power supply (battery) system, for the work of LED illumination, detecting instrument, optical fiber splicer etc. provides power supply.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the top view of the embodiment of the present invention.
Fig. 2 is the front view of the embodiment of the present invention.
Fig. 3 is the base top view of the embodiment of the present invention.
Embodiment
According to Fig. 1, Fig. 2, shown in Fig. 3, the present embodiment is by upper cover, base, and the hinge connected between upper cover and base, the containment housing that quick case pulling buckle combines, between the surface of contact of upper cover and base, silica gel sealing pad is installed, at optical cable wire inlet-outlet up and down between two semicircle orifices, be provided with by high resiliency silica gel sealing ring, when not using this delivery outlet, upper and lower two parts silica gel sealing ring matches, basic seal protection is provided, when there being cable, by cable extruding high resiliency silica gel, cable surrounding is closely wrapped up by the deformation of high resiliency silica gel, reach the object not having Leakage Gas to seal.
The structure of upper cover as shown in Figure 1, at the upper tops of composition casing, be embedded with the transparent windows 4 of a transparent material composition, the lighting device be made up of LED 5 is installed in the inside of view window, and two cover intrinsic safety type combustible gas detectors 6,7 have been installed on case lid, wherein combustable gas concentration in a set of 7 testing environment air, another set of 6 detect box house combustable gas concentration, to grasp the condition of work of working environment at any time; This pick-up unit can be arranged in visual transparent windows 4, also can install at casing top drilling.
Composition graphs 2 we have two gloves holes 11 at the upper cover leading flank of casing as seen, in these two gloves holes, emgloves 24 is installed, during work, both hands is stretched in gloves hole 11, wear silica-gel gloves 24, carry out work at box house.
Chassis interior relative arrangement can be found out in the base top view shown in Fig. 3, wherein there is optical fiber splicer 19, fiber termination box 22, optical fiber construction instrument, consumptive material 18, LED illumination measuring instrument heat sealing machine power supply 17, inert gas steel cylinder 14, explosion-proof type pressure automatic power supply switch 16, pressure regulating valve 15 etc., the inert gas that in case, inert gas steel cylinder 14 forms that surely belongs to wherein forming the present invention the most basic discharges regulator, after casing is closed, under checking the normal situation of each sealing station, can pressure regulating valve switch 15 be opened from box house or open valve switch case, allow high-pressure inert gas (nitrogen, the non-flammable compressive gases such as carbon dioxide) after pressure regulation release be full of housing interior volume, in case, pressure is higher than casing external pressure, form the safe working environment of a no oxygen without inflammable gas, after in casing, pressure reaches set pressure, explosion-proof type pressure power switch connects intrinsic safety type combustible gas detector device power supply, detecting instrument is started working, in case in intrinsic safety type combustible gas detector detection case inflammable gas content below safety value, inflammable gas content in the outer intrinsic safety type inflammable gas testing surrounding air of case below security value (s) after, the output switch of these two detector serial connections just connects LED illumination lamp 5, the power supply of optical fiber splicer 19 grade, equipment preliminary work is ready, then hand is stretched in gloves hole 11, wear emgloves 24, the present invention just can carry out the welding work of optical fiber, when the inflammable gas that the outer intrinsic safety type combustible gas detector of case detects in case external environment air exceeds trouble free service content value, instrument sends chimes of doom and disconnects LED illumination and optical fiber splicer working power immediately, guarantee the safety of welding work, even if there is slight Leakage Gas casing and position, optical cable seal junction, also by the automatic continuous release inert gas of tap changer, ensure casing internal pressure stabilises, when causing inert gas steel cylinder off-capacity in case when working long hours, input external inert gas steel cylinder by external gas interface 8 to work on.
