Detailed description of the invention
For solving to mention problem in background technology, this utility model provides a kind of tubular video camera that can effectively remove mist, including sight glass 1, protecgulum 2 and camera lens 3 that general tubular video camera all has, as depicted in figs. 1 and 2.Tubular video camera generally offers groove 21 at the front end face of protecgulum 2, is used for placing sight glass 1, leaves certain seal clearance 7 between sight glass 1 and protecgulum 2.Common practice is to coat a circle fluid sealant on the medial wall of protecgulum 2 groove 21 to be embedded in groove 21 by sight glass 1 again.Being further typically provided with through hole 22 on protecgulum 2, through hole 22 is connected with groove 21, and groove 21 is " convex " font with through hole 22 longitudinal section integrally.Camera lens 3 is positioned in same light path through through hole 22 and sight glass 1, and leaves space between camera lens 3 and sight glass 1.In prior art, video camera integral sealing effect is not good, and steam is easily accessible fuselage under the day and night temperature difference and arrives formation fog on located anteriorly sight glass 1.For solving prior art existing problems, the rear end face of protecgulum 2 arranges a glue-filling slot 23, make between sight glass 1 and camera lens 3, to form a separate space 5 by encapsulating in glue-filling slot 23 after placing camera lens 3 and focusing, intercepted steam in the video camera fuselage path to sight glass.Additionally, be arranged to deposit the desiccant storage tank 24 of desiccant on protecgulum 2, desiccant storage tank 24 is connected with separate space 5, absorbs the steam in separate space 5 by desiccant.Due to separate space 5 than video camera overall space little a lot, therefore the steam in space is easier to be absorbed.Even if the sealing of the seal clearance 7 between sight glass 1 and protecgulum 2 is not firm causes that steam enters separate space, but owing to separate space 5 is narrow and small, steam in space still can quickly be absorbed, it is ensured that the relatively dry in separate space 5, it is to avoid sight glass hazes.
Desiccant storage tank 24 is usually with the center of circle of through hole 22 for the center of circle, the circular groove of formation, naturally it is also possible to be other shapes, for instance square groove etc..As a kind of embodiment more optimized, by the desiccant storage tank 24 diameter d diameter D being set smaller than sight glass 1, shorten the path between desiccant and separate space 5, be conducive to desiccant to absorb the steam in separate space 5 quickly.Owing to after encapsulating, video camera dismounting comparatively bothers, therefore to avoid situation that is as bad with the sealing of protecgulum 2 in sight glass 1 and that have steam to enter always, multiple desiccant storage tank can be set.
As another preferred implementation, in order to avoid the glue in glue-filling slot 23 flows to through hole 22, before encapsulating can first sheathed catch 6 encapsulating again on the lens barrel of camera lens 3, catch 6 is positioned at the connecting portion of glue-filling slot and through hole.
As another preferred implementation, in order to facilitate encapsulating, the side of glue-filling slot 23 can be arranged to the domatic of certain angle, and peristome diameter is more than the diameter with through hole connecting portion, specifically as shown in Figure 3.
Applicant's effect by following two verification experimental verification this utility model tubular video camera.
Set the 1# tubular video camera model machine as this utility model structure, the existing tubular video camera model machine of 2#.
1, the antifog test of natural cooling (as shown in Fig. 4 a, 4b)
Step is as follows:
(1) uncap before 1#, 2# prototype test at high temperature+60 DEG C, toast the concordance ensureing internal medium humidity for 2 hours；
(2) 1#, 2# model machine puts into wet paper towel after having toasted, and places protecgulum 2 rubber and is sealed by protecgulum 2, tightens protecgulum 2 screw；
(3) again 1#, 2# model machine is placed in the environmental cabinet of high temperature+60 DEG C and toasts 2 hours so that separate space 5 is internally formed hot and humid environment；
(4) 1#, 2# model machine is placed normal temperature environment lower 2 hours.
Result: along with equipment cooling protecgulum 2 sight glass 1 is lowered the temperature comparatively fast, 2# sight glass 1 quickly condenses fog, and 1# only has a small amount of fog to equipment cooling and occurs, is about the 25% of 2# model machine fog total amount.
2, the condensing agent antifog test of cooling (as shown in Fig. 5 a, 5b)
Step is as follows:
After finishing test 1, treat 1#, 2# model machine natural cooling, adopt condensing agent to spray the sight glass 1 of 1# and 2# model machine, allow sight glass 1 quickly cool down the anti-fog performance of checking video camera.
Result: 1# model machine is jetted through still not hazing afterwards in condensation, and 2# model machine fog becomes apparent from, through calculating about the 20% of the mist quantity that mist quantity is 2# model machine of 1# model machine.
May certify that this utility model has blocked the steam path to sight glass 1 by above-mentioned two test, additionally due to separate space 5 is narrow and small, it is readily available desiccant and absorbs the steam in separate space, keep the relatively dry in separate space 5 to avoid sight glass 1 to haze, except fog effect is good.In addition, this utility model is little to structural change, with low cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacements, improvement etc., should be included within the scope that this utility model is protected.
