Description
Technical field
It the utility model is related to industrial endoscope field, more particularly to minor diameter hot industry endoscope cooling device.
Background technology
Industrial endoscope is integrate optics, precision optical machinery, electric mechanical, electronic technology and microimaging technology new
Type detector for non-destructive examination device, be usually used in precision optical machinery, pipeline, boiler, inside container, airplane turbine, blade, engine, combustion
Burn cavity etc..Non-Destructive Testing can be carried out to device interior in the case where that need not dismantle or destroy assembling.
After equipment fault shutdown or boiler are shut down because of booster, if damage part is not detected and repaired immediately, it will make
Into great property loss, it is generally the case that need to carry out internal detection by industrial endoscope during maintenance, determine the source of trouble
Head, then specific aim solve, but now temperature is by there is hundreds of degrees Celsius in equipment or boiler tube, and regular industrial endoscope is because of insertion
Pipe diameter is excessive, can not stretch into device interior and be detected.
China Patent No.：201520912513.X, entitled " high temperature work is used in a kind of gas-turbine combustion chamber or turbine experiment
Industry
Endoscope ".
Above patent is disadvantageous in that：
1st, inhomogeneous cooling is even, and local temperature is too high；
2nd, diameter is too big, it is impossible to is used in accurate, narrow regions；
3rd, water cooling needs not timing to change pure water, easily blocks cooling duct by impurity；
4th, the flow velocity of water is slow, and cooling efficiency is low；
5th, the damage that leakage easily causes equipment once occurs for water stream channel.
Prior art is taken away thermal source by circulating for water, and defect is that aqueduct is smaller, and flow velocity is low, for a long time not
Incrustation scale is formed so as to block aqueduct using easy；The damage of equipment can be caused after leakage, and detection probe can not do small, inspection
The environment and condition of survey are by serious limitation.
Utility model content
It is cold that the purpose of this utility model is to provide the minor diameter industrial endoscope cooled down in high temperature environments to air
But device.
The technical solution of the utility model is as follows：
Minor diameter hot industry endoscope cooling device, is enclosed on insert tube of endoscope, the insert tube of endoscope top
Portion is provided with shooting part, including double thread air-guide part positioned at insert tube of endoscope tip exterior and connection air admission hole with it is double
The airway tube of line screw thread air-guide part, the double thread air-guide part are internally provided with screw thread shape air guide channel, the double thread
Air-guide part top ends are provided with multiple steam vents, and compressed gas enters from the air admission hole, flow through airway tube, double thread air guide
Air guide channel in part, finally discharged from steam vent.
Above-mentioned shooting part is nearby provided with temperature sensor.
Above-mentioned steam vent is 4.
Above-mentioned air admission hole is located at industrial endoscope handheld terminal.
Above-mentioned air guide tube material is high temperature resistant Teflon.
Multiple guiding joint pieces are provided with the outside of above-mentioned airway tube.
Further, the steel wire rope of the traction guiding joint piece is included.
The beneficial effects of the utility model：The utility model uses the type of cooling of outer circulation air-flow, and gases at high pressure are led to
Cross airway tube and guide to front-end probe position, taken away thermal source using the quick flowing of air, compressed air is suffered in conduit
Resistance ratios water it is small, flow velocity is also just faster than the flow velocity of water, it is achieved thereby that efficient cooling effect, will not be made because of leakage
Into potential risk；High temperature alarm function is added, the change of temperature is monitored in real time, avoids causing because environment temperature is too high
The damage of component；The air-flow of insert tube of endoscope front end can carry out dedusting cleaning to being detected surface of position, can be more straight
That sees detect；When tested interior of articles has steam, smog or dust, the air-flow of discharge can dispel the medium of air
Open, avoid detection sight hindered；The damage of leakage caused tested object or equipment of itself is prevented；Detecting caliber can
To do very little, so as to break water-cooling pattern because the limitation that diameter reason is formed.
