Abstract
The utility model discloses a sealed type infrared window. The sealed type infrared window comprises a flange mounting seat provided with a through hole; an infrared optical crystal is arranged in the through hole of the flange mounting seat; the inner wall surface and the outer wall surface of the through hole are respectively provided with closely-pitched screw threads; the outer wall surface of the through hole is in screwed connection with an external fastening ring through the closely-pitched screw threads; the inner wall surface of the through hole is in screwed connection with an inner pressing ring through the closely-pitched screw threads; the infrared optical crystal is fixedly connected with the flange mounting seat through the inner pressing ring; an O-shaped sealing ring is respectively arranged between the inner pressing ring, the infrared optical crystal and the flange mounting seat; portions where the O-shaped sealing rings contact with the inner pressing ring, the infrared optical crystal and the flange mounting seat are provided with double-faced adhesive layers; the diameter of the infrared optical crystal is smaller than the diameter of the through hole; an annular gap is formed between the infrared optical crystal and the through hole; and the annular gap is filled with silicone rubber. With the sealed type infrared window of the utility model adopted, the problem of difficulty in realizing sealing, dust prevention and crystal material protection when an existing infrared window is in harsh environments such as high-voltage, high-current and outdoor environments can be solved.
Description
technical field:
The utility model relates to a kind of infrared detecting device, is specifically related to a kind of closed type infrared window.
background technology:
Along with the fast development of power industry, high-tension distribution equipment, as equipment indispensable in electric power transfer, plays an important role in power supply.Unbalanced due to each department electricity consumption and load, cause the overload hot operation as long-time in the position such as switch contact and bus bar of high-tension distribution equipment part parts, because lack the detection means of relative efficiency, the temperature of these heating positions cannot accurately be monitored, easily cause thus power distribution cabinet overheat accident, cause fire and large-area power-cuts.In sum, find in advance and get rid of hot stall, safety and reliability service to electric system all have very important significance.
Along with the effect that noctovisor scan is differentiated at electric power heating accident is increasing; airtight electric equipment infrared temperature measurement window application is drawn more and more; infrared window is arranged on the housing of high-tension switch cabinet; to having relatively high expectations of dustproof, sealing, antidetonation; traditional infrared window is difficult to play sealing simultaneously, prevent dust and protect the effect of crystalline material in the rugged surroundings such as high pressure, large electric current, open air; the serviceable life of infrared window is short, and maintenance times is many, also needs to shut down to safeguard serious time.
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of closed type infrared window.This technical scheme efficiently solves existing infrared window very difficult problem that plays sealing simultaneously, prevents dust and protect crystalline material in the rugged surroundings such as high pressure, large electric current, open air.
The utility model is achieved through the following technical solutions:
A kind of closed type infrared window, comprise the flange mount pad (1) that is provided with through hole (2), in the through hole (2) of flange mount pad (1), be provided with crystal for infrared use (3), it is characterized in that: through hole (2) internal face (21), outside wall surface (22) is provided with fine thread (4), outside wall surface (22) is by fine thread (4) outer straining ring (5) that spins, internal face (21) is connected with interior trim ring (6) by fine thread (4), crystal for infrared use (3) is fixedly connected with flange mount pad (1) by interior trim ring (6), interior trim ring (6), crystal for infrared use (3), between flange mount pad (1), be provided with O RunddichtringO (7), O RunddichtringO (7) and interior trim ring (6), crystal for infrared use (3), flange mount pad (1) contact site is provided with layers of two-sided (8), described crystal for infrared use (3) diameter is less than through hole (2) diameter, between crystal for infrared use (3) and through hole (2), form annular gap (9), in annular gap (9), be filled with silicon rubber (10).
The further Technological improvement plan of the utility model is:
Described annular gap (9) is positioned between through hole (2) internal face (21) fine thread (4) and the outward flange of crystal for infrared use (3).
The further Technological improvement plan of the utility model is:
The silicon rubber (10) of filling in described annular gap (9) by point gum machine encapsulating, fill formation.
The utility model compared with prior art, has following obvious advantage:
One, crystal for infrared use diameter of the present utility model is less than through-hole diameter, between crystal for infrared use and through hole, form annular gap, and be filled with silicon rubber, on the wall of one of annular gap, there is fine thread, silicon rubber and annular gap adhesion are improved, having changed traditional crystal for infrared use edge is directly connected firmly with metal installation base, and gapped sealing effectiveness is poor, annular gap has avoided optical crystal to be connected with the direct of mount pad, silicon rubber not only can improve the sealing property of infrared window, and when infrared window is subject to violence impact, also play certain buffer action, protect crystalline material.
Two, between the interior trim ring of the utility model infrared window, crystal for infrared use, flange mount pad, be provided with O RunddichtringO, O RunddichtringO and interior trim ring, crystal for infrared use, flange mount pad contact site are provided with layers of two-sided, can further improve the sealing of infrared window.
brief description of the drawings:
Fig. 1 is structural representation schematic diagram of the present utility model.
embodiment:
As shown in Figure 1, the utility model comprises the flange mount pad 1 that is provided with through hole 2, flange mount pad 1 is connected with distribution setting by through hole 2, flange mount pad 1 and distribution arrange on the end face of junction grommet type seals are set, grommet type seals is connected with flange mount pad 1 by the annular seal groove arranging on flange mount pad 1 inner face, the height of grommet type seals protrudes from end face, improve the connection sealing that flange mount pad 1 and distribution arrange, in the through hole 2 of flange mount pad 1, be provided with crystal for infrared use 3, through hole 2 internal faces 21, outside wall surface 22 is provided with fine thread 4, outside wall surface 22 is by fine thread 4 outer straining ring 5 that spins, internal face 21 is connected with interior trim ring 6 by fine thread 4, crystal for infrared use 3 is fixedly connected with flange mount pad 1 by interior trim ring 6, interior trim ring 6, crystal for infrared use 3, between flange mount pad 1, be provided with O RunddichtringO 7, O RunddichtringO 7 and interior trim ring 6, crystal for infrared use 3, flange mount pad 1 contact site is provided with layers of two-sided 8, crystal for infrared use 3 diameters are less than through hole 2 diameters, between crystal for infrared use 3 and through hole 2, form annular gap 9, in annular gap 9, be filled with silicon rubber 10, annular gap 9 is between through hole 2 internal face 21 fine threads 4 and the outward flange of crystal for infrared use 3, the silicon rubber 10 of annular gap 9 interior fillings is by point gum machine encapsulating, fill formation.
