Abstract
The utility model is a kind of environmental test chamber's image-type fire detector or camera protective cover, the shield is hollow column structure, it is characterized by: there is a gas vent (2) to communicate above the side wall (9) of shield with inner cavity, there is an air inlet (1) to communicate below shield side wall (9) with inner cavity, outlet hole (3) are set on the rear end cap (7) of shield and entrance hole (4) is communicated with inner cavity, double pane (5) are installed at the center of the drive end bearing bracket (8) of shield, air hole (6), which are machined with, in the edge of double pane (5) blows brush inner glass eyeglass for compressed air.After image-type fire detector or camera detection, protective cover forms the outside protective covers of a completion, and image-type fire detector or video camera are coated on the intracavitary portion of type completely；It effectively avoids the occurrence of image-type fire detector or video camera dust accumulation, contamination, haze and icing.
Description
Technical field
The utility model is a kind of environmental test chamber's image-type fire detector or camera protective cover, belongs to the knot of product
Structure technical field.
Background technique
It is -50 ° in temperature --- under conditions of 70 °, humidity≤95% (0 DEG C~52 DEG C), existing environmental test chamber's image
Formula fire detector or camera protective cover be easy to appear equipment icing or damage the phenomenon that, thus bring to maintain equipment at
This practical problem very high, that maintenance risk is big.
Summary of the invention
The utility model exactly designs in view of the above-mentioned deficiencies in the prior art and provides a kind of environmental test chamber
Image-type fire detector or camera protective cover, the purpose is to avoid camera lens from being exposed to extraneous low temperature and high temperature for a long time
And the phenomenon that causing its equipment icing or damage, effective solution bring maintenance cost due to maintain equipment is high, maintenance wind
The big practical problem in danger.
The purpose of this utility model is achieved through the following technical solutions:
This kind of environmental test chamber's image-type fire detector or camera protective cover, the shield are hollow column knot
Structure, it is characterised in that: there is a gas vent 2 to communicate with inner cavity in the top of the side wall 9 of shield, under shield side wall 9
Fang Youyi air inlet 1 is communicated with inner cavity, and outlet hole 3 is arranged on the rear end cap 7 of shield and entrance hole 4 is communicated with inner cavity,
Double pane 5 is installed at the center of the drive end bearing bracket 8 of shield, is machined with air hole 6 in the edge of double pane 5
Brush inner glass eyeglass is blown for compressed air.
The shield is made of stainless steel material.The rear end cap 7 of shield is double-layer structure.
Shield described in the utility model has the advantage that
1 protecting effect is good, and protective cover forms a complete outside protective covers, completely by image-type fire detector or camera shooting
Machine is coated on the intracavitary portion of type；It effectively avoids image-type fire detector or camera lens dust accumulation, contamination, haze and icing feelings
The generation of condition；
2 structures are simple, versatile, the utility model protective cover into compressed air mouth, go out compressed air mouth, form and remove
Dirt interface, incoming line can individually be customized according to different types of video camera, can be visited mounted in different types of image-type fire
It surveys on device or camera lens；
3 selections are particular about, and the utility model protective cover is manufactured using stainless steel material, and intensity is high, corrosion-resistant, light-weight.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of shield described in the utility model
Specific embodiment
Technical solutions of the utility model are further described below with reference to drawings and examples:
Referring to figure 1, this kind of environmental test chamber's image-type fire detector or camera protective cover are hollow column
Shape structure, outer dimension Φ 250X370, interior chamber size Φ 150X280 have a gas vent in the top of the side wall 9 of shield
2 communicate with inner cavity, have an air inlet 1 to communicate with inner cavity in the lower section of shield side wall 9, set on the rear end cap 7 of shield
It sets outlet hole 3 and entrance hole 4 is communicated with inner cavity, double pane 5, window are installed at the center of the drive end bearing bracket 8 of shield
Glass size is Φ 65mm, is machined with air hole 6 in the edge of double pane 5 and blows brush inner glass mirror for compressed air
Piece.
The shield is made of stainless steel 06Gr18Ni9.Anti-corrosion, antirust while proof strength.The rear end of shield
Lid 7 is double-layer structure.
This kind of shield can be -50 ° in temperature --- under conditions of 70 °, humidity≤95% (0 DEG C~52 DEG C), image-type
Fire detector or video camera are coated on protective cover inside cavity.
After image-type fire detector or camera detection, protective cover forms the outside protective covers of a completion, complete
Image-type fire detector or video camera are coated on the intracavitary portion of type entirely；Effectively avoid image-type fire detector or video camera
Dust accumulation, contamination haze and the occurrence of icing.
