Summary of the invention
According to background technology, the objective of the invention is to overcome existing similar products and can not when welding, carry out process monitoring, or monitoring equipment is comparatively complicated and huge shortcoming, provide a kind of by draining cover body, midget with miniaturely weld under water that the optical fiber sight glass forms, midget and miniaturely weld the top that the optical fiber sight glass is installed in the draining cover body under water, the drainage cover bottom is equipped with the underwater sealing device, form the gas that allows in the cover and discharge, weld small-sized drainage arrangement but the outer water of cover can not enter the local dry-type of weld zone.
To achieve these goals, the present invention is achieved through the following technical solutions:
A kind of local dry-type welds small-sized drainage arrangement, mainly by the draining cover body, midget and the miniature optical fiber sight glass that welds are under water formed, wherein: the draining cover body is mainly by upper end cover, lock sleeve, the infiltration cover, bottom end cover, sealing shroud and draining sponge are formed, the lock sleeve upper and lower side respectively with upper end cover, bottom end cover is spirally connected and sealing ring is installed, inner chamber at lock sleeve embeds an infiltration cover, the infiltration cover is connected with upper end cover, at bottom end cover, the below of lock sleeve and infiltration cover embeds the draining sponge, and the draining sponge is bonded together with it, overlap one deck sealing shroud around the draining sponge, cover body and workpiece to be welded form an airtight space under water; Put boring at upper end cover and infiltration, the welding gun hole is used for being connected and fixed midget in the draining cover body, the air filter that connects gases at high pressure by the high pressure gas body opening, insert the miniature optical fiber sight glass that welds under water by the sight glass hole, and seal respectively with upper end cover, around its air filter is filter screen, and the lower end is an entity.
Connecting hole and water jets under high pressure hole are set on the described cover body upper end cover, and the slit between water jets under high pressure hole and lock sleeve and the infiltration cover communicates.
Correct position on the described upper end cover is provided with welding robot human body's connecting hole.
Owing to adopt technique scheme, the utlity model has following advantage and effect:
1, the utility model is simple in structure, and cost is lower, is easy to promote;
2, the utility model welds the optical fiber sight glass under water because of adopting miniature welding gun and type, thereby the cover body inside dimension is reduced greatly, not only makes to be beneficial to more with welding robot to be used, and has shortened greatly and discharged the cover body required time of maritime interior waters.
3, the miniature advantages such as the optical fiber sight glass has the resolution ratio height, speed is strong, the visual field is big, volume is little, operation is light and handy, long service life of welding under water of the utility model employing, miniature weld under water the optical fiber sight glass integrated the visiting light source, may ultimately reach the purpose of welding situation in the long-range clear observation cover body.
4, the utility model adopts the mode of upper end infiltration, and it is moistening to remain cavernous body, can prevent the carrying out along with welding, the scaling loss cavernous body, and make water inlet in the cover body.

The specific embodiment
Illustrate by Fig. 1, a kind of local dry-type welds small-sized drainage arrangement, mainly by draining cover body 1, midget 2 and the miniature optical fiber sight glass 3 that welds are under water formed, wherein: draining cover body 1 is mainly by upper end cover 10, lock sleeve 11, infiltration cover 12, bottom end cover 13, sealing shroud 14 and draining sponge 15 are formed, lock sleeve 11 upper and lower sides respectively with upper end cover 10, bottom end cover 13 is spirally connected and sealing ring 16 is installed, inner chamber at lock sleeve 11 embeds an infiltration cover 12, infiltration cover 12 is connected with upper end cover 10, at bottom end cover 13, the below of lock sleeve 11 and infiltration cover 12 embeds draining sponge 15, and draining sponge 15 is bonded together with it, overlap one deck sealing shroud 14 around draining sponge 15, cover body 1 and workpiece to be welded 17 form an airtight space under water; Boring on upper end cover 10 and infiltration cover 12, welding gun hole 21 is used for being connected and fixed midget 2 in draining cover body 1, the air filter 4 that connects gases at high pressure by high pressure gas body opening 20, insert the miniature optical fiber sight glass 3 that welds under water by sight glass hole 22, and seal respectively with upper end cover 10, around its air filter 4 is filter screen, and the lower end is an entity.
Other knows, be filter screen around the air filter 4, and the lower surface is an entity, gases at high pressure are injected after filter screen is broken up the back from discharging all around, and directly do not inject from the bottom, make gas in cover, form circulation like this, avoid the direct injection of gases at high pressure and electric arc is produced disturbance.
On cover body upper end cover 10, also be provided with connecting hole 18 and water jets under high pressure hole 19, can go into slit between lock sleeve 11 and the infiltration cover 12 along orifice flow through the seawater of pressurization, directly arrive draining sponge 15 from the upper end, prevent to make in the cover body and intake along with the carrying out scaling loss draining sponge 15 of welding.
Specific implementation process is as follows: make draining sponge 15 compress workpiece 17 to be welded after 1 entry of draining cover body, make cover body 1 form a confined space under water, inject gases at high pressure then, seawater is forced out between draining sponge 15 and workpiece 17, utilize humidity detector to detect striking welding when reaching the striking condition in the confined space.During welding, electric arc is in cover body 1 internal combustion, and the steam when gas that solder wire material self is produced and water vapor is more and more, pressure in the cover body 1 is increasing, and at this moment, draining sponge 15 has played the effect of " check valve ", unnecessary gas in the cover body 1 is discharged, and seawater can not enter; Moreover, miniature weld under water optical fiber sight glass 3 integrated the visiting light source, may ultimately reach the purpose of welding situation in the long-range clear observation cover body, thereby reached the purpose of local dry-type welding.
