Abstract
The invention discloses an anti-frozen glass lens of a camera. The anti-frozen glass lens comprises two stacked glass lens bodies (1). A resistance wire (2) is clamped between the two stacked glass lens bodies (1). The resistance wire (2) is arranged along the peripheries of the stacked glass lens bodies (1), and two ends of the resistance wire extend out of the lens bodies. During use, a lens of the camera executing a video monitoring task is replaced, two ends of the resistance wire (2) of the glass lens bodies (1) are connected with a power supply of the camera, and when ice covers the replaced glass lens bodies (1) as the lens of the camera, the resistance wire (2) is started to heat to melt the covering ice on the surface of the lens. The anti-frozen lens solves the problem that when the ice covers the camera, a picture can not be shot clearly; solves the problem that the camera can no longer be used under a frozen environment; and widens an application environment range of the camera.
Description
Technical field
The invention belongs to optical technical field, relate to the freezing glass mirror of a kind of anti-video camera.This eyeglass prevents that the camera lens experience is freezing before being applicable to and covering camera lens under the freezing environment.
Background technology
At present, along with the video monitoring The Application of Technology more and more widely, the applied environment of video camera also presents the trend that becomes increasingly complex, and the performance of video camera has also been proposed more stern challenge.In other words, video camera not only will have the function of water proof and dust proof, also will have resistant to elevated temperatures function.In addition, be installed on open-air video camera and also will have anti-freezing function.Yet concerning being installed on open-air video camera at present, the low temperature and high relative humidity environment in winter is very easily given the waterproof glass icing of video camera, in case the waterproof glass icing of video camera, video camera is lost monitoring capacity immediately, and its picture shot moment thickens unclear.So even current pressing for developed a kind ofly under freezing environment, the video camera glass mirror faces icing when threatening, also pictures taken clearly, thus do not influence the glass mirror of video monitoring effect at all.
Summary of the invention
The technical problem to be solved in the present invention is at the defective of prior art, to provide a kind of anti-video camera freezing glass mirror.This eyeglass can overcome and is installed on open-air high-speed dome camera at present and meets with at eyeglass and be difficult to the clearly difficulty of pictures taken when icing thickens, and makes its pictures taken clearly still under freezing environment, still can be competent at video monitoring.
Technical scheme of the present invention is, the freezing glass mirror of described anti-video camera, and referring to accompanying drawing 1, it comprises two stacked glass mirror 1 as shown in Figure 1.Its technical characterstic is that between described two stacked glass mirror 1, also clamping has a resistance wire 2.Between these two stacked glass mirror 1, stretch out outside these two stacked glass mirror 1 by this termination, resistance wire 2 two ends along the periphery of described glass mirror 1 for this resistance wire 2.The size of described two stacked glass mirror 1 is mated with the size of the video camera eyeglass of carrying out vision control task.
Principle of work of the present invention is: when the freezing glass mirror of the anti-video camera of Gou Chenging uses thus, it is replaced the eyeglass of the video camera of carrying out vision control task, and the two ends that will stretch out the resistance wire 2 of glass mirror 1 insert the power supply of video camera, are come the power supply supply of controlling resistance silk 2 by the power switch of this video camera.Like this, this resistance wire 2 becomes the heating element of video camera.When changing the glass mirror 1 surperficial icing of making the video camera eyeglass, power switch starting resistance silk 2 by video camera, resistance wire 2 heatings, heat passes to transparent glass sheet 1 equably by the resistance wire 2 that is arranged in glass mirror 1 periphery, thus one, the glass mirror 1 that obtains heat can utilize heat to melt its surperficial icing, reach the effect that prevents that camera lens is freezing, even make the video camera of carrying out vision control task meet with icing simultaneously, the clearly pictures taken that also can do as usual under freezing environment continues to carry out the task of video monitoring.
The invention has the beneficial effects as follows:
1), solved video camera can not be known pictures taken when the lens surface icing causes lens blur a difficult problem;
2), solved the problem that video camera can not continue to use under freezing environment;
3), enlarged the applied environment scope of video camera.
Description of drawings:
Fig. 1 is the structural representation of the anti-specific embodiment of the freezing glass mirror of video camera of the present invention, is denoted as among the figure:
1-glass mirror,
2-resistance wire.
Embodiment:
Referring to accompanying drawing 1, Figure 1 shows that the present invention prevents specific embodiment of the freezing glass mirror of video camera.The HGB-TP-2M type clear glass eyeglass that glass mirror 1 among this embodiment adopts the permanent luminescence of China Shenzhen Products Co., Ltd to produce, lens edge is useful on the square groove that resistance wire is installed.The thick 2mm of this glass mirror, the transmittance height, high temperature resistant; Resistance wire 2 adopts Hunan China to economize the HCDL-R-05D12-20 type resistance wire that the pure Power Tech Corp. Inc. of remittance produces, and input voltage is 12～24V direct current, and direct current resistance is 20～30 ohm, and the resistance wire surface scribbles one deck insulating material.Between above-mentioned glass mirror 1 and the resistance wire 2, by technique scheme and with reference to connection shown in Figure 1.The i.e. stacked in opposite directions stickup of two sheet glass eyeglasses 1, clamping resistance wire 2 between the two.The size of two stacked glass mirror 1 is mated with the size of the video camera eyeglass of carrying out vision control task.Between these two stacked glass mirror 1, namely go in the square groove of two sheet glass eyeglasses 1 by down along the periphery of described glass mirror 1 for described resistance wire 2.Stretch out outside these two stacked glass mirror 1 termination, resistance wire 2 two ends, can insert video camera internal electric source control end during use.By this embodiment of the anti-freezing glass mirror of video camera of above the present invention who constitutes, be proved to be respond well through manufacturing experimently to try out, reach designing requirement fully.
Claims (1)
1. freezing glass mirror of anti-video camera, it comprises two stacked glass mirror (1), it is characterized in that, between described two stacked glass mirror (1), also clamping has a resistance wire (2), this resistance wire (2) along the periphery of described glass mirror (1) between these two stacked glass mirror (1), stretch out outside these two stacked glass mirror (1) this resistance wire (2) termination, two ends, and the size of described two stacked glass mirror (1) is mated with the size of the video camera eyeglass of carrying out vision control task.
