Abstract
The utility model relates to a novel SF6 gas imager, comprising a CO2 laser, a visible light imaging unit, and an infrared imaging unit which are respectively connected with a switch power supply, wherein in front of the CO2 laser there is provided a laser emitting lens, in front of the visible light imaging unit there is provided a visible light receiving lens, in front of the infrared imaging unit there is provided an infrared receiving lens, the visible light imaging unit and the infrared imaging unit are connected with a central processing unit, the central processing unit is connected with a display, and the laser emitting lens is a diffusion lens. The novel SF6 gas imager has the beneficial effects that in front of the laser there is provided the diffusion lens, and the diffusion angle of the diffusion leans is same as the view field angle of the infrared receiving lens, thereby enabling the diffusion lens to better diffusing and focusing laser energy.
Description
Technical field
The utility model relates to SF
6The gas leakage of gas detects, especially a kind of novel SF
6The gas imaging instrument.
Background technology
SF
6Electrical equipment is used more and more, and ageing equipment causes gas leakage to happen occasionally.Conventional leak hunting method has: bandaging strapping, brush soap bubble method, qualitative, quantitative leak locator method, and these methods all need power failure operation, and not only workload is large, and key is to be difficult to accurately location leak source.The SF that utilizes infrared detection technique to realize
6Characteristics highly sensitive, that volume is little, cost performance is high that the gas imaging instrument has, key are can be to the SF that leaks
6Gas carries out colored eye-catching processing.But the energy control for generating laser output is the problem that needs solve.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of and can export the novel SF that energy is regulated to generating laser
6The gas imaging instrument.
The utility model solves the technical scheme that its technical matters adopts: this novel SF
6The gas imaging instrument comprises the CO that is connected with Switching Power Supply respectively
2Laser instrument, visual light imaging unit, infrared imaging unit, CO
2Be provided with the Laser emission camera lens before the laser instrument, be provided with visible light before the visual light imaging unit and receive camera lens, be provided with infrared reception camera lens before the infrared imaging unit, visual light imaging unit, infrared imaging unit are connected with CPU (central processing unit), CPU (central processing unit) is connected with display, and described Laser emission camera lens is the diffusion mirror.
As preferably, the spread angle of described diffusion mirror is identical with the field angle of infrared reception camera lens.
As preferably, described Switching Power Supply is connected with fan.
The effect that utility model is useful is: in the utility model, be provided with the diffusion mirror before the laser instrument, its spread angle is identical with the field angle of infrared reception camera lens, has realized that better the diffusion mirror spreads laser energy and converges.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: such as Fig. 1, this novel SF
6The gas imaging instrument comprises the CO that is connected with Switching Power Supply respectively
2Laser instrument, visual light imaging unit, infrared imaging unit, CO
2Be provided with the Laser emission camera lens before the laser instrument, be provided with visible light before the visual light imaging unit and receive camera lens, be provided with infrared reception camera lens before the infrared imaging unit, visual light imaging unit, infrared imaging unit are connected with CPU (central processing unit), CPU (central processing unit) is connected with display, and described Laser emission camera lens is the diffusion mirror.
CO
2Laser instrument is launched continuous laser, expands amplification through the diffusion mirror, forms a uniform shadow surface, and this shadow surface is target area to be detected.And be converted into digital signal transfers to CPU (central processing unit) by visible light and infrared two light paths.Merge and contrast by visible light and infrared image, accurately locate rapidly leakage point, and shown by display.In order to realize CO
2The control of laser instrument output energy, CO
2Laser instrument output energy signal is connected with master control module controls, and is realized regulating by main control module and diffusion mirror.In order to realize that better the diffusion mirror spreads laser energy and converges, the spread angle of diffusion mirror is identical with the field angle of infrared reception camera lens.
Wherein, Switching Power Supply is connected with fan, has better guaranteed the Systems balanth operation.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
