Description
Technical field
The present invention relates to electric device maintenance technical field, more particularly to a kind of reactor inner surface flashover discharges two-sided detection imaging system.
Background technology
In existing reactor inner surface discharge detecting technique, the Chinese invention patent of Patent No. CN200710056323 describes " internal surface of dry hollow reactor detection method and device ", as shown in Figure 1, although the detection means can carry out two-sided detection to reactor simultaneously, but the picture of 2 one-tenth of the inner surface of reactor both sides is reflexed to CCD 3 using two pieces of opposed glass right-angle prisms 1 by its imaging system, as detection means is in assembling process, the more difficult fixation of two pieces of opposed right-angle prisms, and it is difficult to ensure that two pieces of prism relative positions of card are constant, it is likely to result in the unclear problem of imaging, in addition, in the detection means course of work, the prism of glass material is easily damaged.
The content of the invention
The technical problem to be solved in the present invention, it is to overcome in existing reactor inner surface discharge detecting technique, imaging system is difficult assembling and flimsy deficiency using two pieces of opposed glass right-angle prisms, there is provided a kind of reactor inner surface flashover electric discharge double-side detecting device imaging system.
The present invention solves the problems, such as that the technical scheme adopted by reactor inner surface discharge detecting technique is：Construct a kind of two-sided detection imaging system of reactor inner surface flashover electric discharge, including rectangle box body, and a metal isosceles right-angle prismatic post being arranged on below in box body, a minisize pick-up head for being arranged on cartridge upper surface, and the LED for illumination arranged around the minisize pick-up head surrounding, the plane that described two right-angle sides of metal isosceles right-angle prismatic post and rib are located respectively constitutes two working faces, reflectance coating is coated with two working faces, makes reflectivity reach more than 90%；The metal isosceles right-angle prismatic post is fixed on lower surface in rectangular box body, a slot is opened respectively on two faces of the rectangle box body relative with described two working faces of metal isosceles right-angle prismatic post, so that two working faces of metal triangular prism are respectively toward to the relative inner surface to be detected of reactor two, the light of two inner surface reflections to be detected is enable to be mapped on two working faces of triangular prism completely.
Discharge in two-sided detection imaging system in above-mentioned reactor inner surface flashover, also include connecting the computer of the minisize pick-up head by signal transmssion line.
Implement the two-sided detection imaging system of reactor inner surface flashover electric discharge of the present invention, due to using metal isosceles right-angle prismatic post, overcome existing two pieces opposed glass right-angle prisms and be difficult assembling and flimsy deficiency, also so that the stability of image quality is improved, also improve reactor inner surface flashover electric discharge double-side detecting device imaging system service life.Right-angle prism in its device with metal isosceles right-angle prismatic post replacement prior art of the invention, and then easily assemble, it is hardly damaged, two working face plating reflectance coatings that two right-angle sides of metal isosceles right-angle prismatic post and rib place plane are constituted make reflectivity reach more than 90%.
Description of the drawings
Accompanying drawing 1 is prior art reactor Inner surface test method and device structural representation.
Accompanying drawing 2 is a kind of reactor inner surface flashover electric discharge double-side detecting device imaging system structural representation of the invention.
With reference to the accompanying drawings and examples, the characteristics of illustrating technical solution of the present invention.
As shown in Figure 2, the two-sided detection imaging system of reactor inner surface flashover electric discharge that the present invention is provided includes rectangle box body 7, there are 4, minisize pick-up head 5 of a metal isosceles right-angle prismatic post and the LED 6 for illumination around minisize pick-up head surrounding in rectangular box body, they are arranged in a rectangle box body 7.
Two faces that the plane that 4 two right-angle sides of metal isosceles right-angle prismatic post and rib are located is constituted are working face 8, are to improve reflective function, have plated reflectance coating in two working faces 8, make the reflectivity of two working faces 8 reach more than 90%.
Such as Fig. 2, metal isosceles right-angle prismatic post 4 is fixed on lower surface 9 in rectangle box body 7, two working faces 8 are respectively toward to the relative inner surface 10 to be detected of reactor two, a slot 11 is opened respectively on two sides of the rectangle box body 7 relative with two working faces 8, light and image for the inner surface 10 to be detected that makes reactor two relative and directly pass through, also so that completely unobstructed between two inner surfaces to be detected 10 of two working faces 8 and reactor, the light for so being reflected by two inner surfaces 10 to be detected of reactor can be mapped on two working faces 8 completely.
As shown in Fig. 2 minisize pick-up head 5 is fixed on the center of upper surface 12 in rectangle box body 7, namely the surface of metal isosceles right-angle prismatic post 4, at the top of box body 7, multiple LEDs 6 for providing lighting source are installed with around 5 surrounding of minisize pick-up head.
The two-sided detection imaging system images process of reactor inner surface flashover electric discharge of the present invention is such, the illumination that LED 6 sends is mapped on the relative inner surface 10 to be detected of reactor two, after being reflected by reactor inner surface 10 to be detected, incided on two working faces 8 of metal isosceles right-angle prismatic post 4 by two slots 11 on 7 two sides of rectangle box body, and minisize pick-up head 5 is reflexed to by two working faces 8.Minisize pick-up head 5 is connected with computer 14 by signal transmssion line 13, and the image that minisize pick-up head 5 is absorbed is sent in computer 14, and to carry out real-time detection to reactor inner surface situation, the image for absorbing can be observed and can also preserve or send.
The above; the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, any those familiar with the art the invention discloses technical scope in; the change or replacement that can be readily occurred in, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
