The endoscope for pipeline inspection comprises an endoscope body, wherein a lens device is arranged at the front end of the endoscope body; a light-emitting plate is clamped on the lens device; a rotating plate is clamped on the lens device and is positioned under the light-emitting plate; the rotating plate is connected with a connecting plate through a connecting part; a circular hole is formed in the rotating plate; a circle of LED (Light-Emitting Lamp) lamps for illumination are arranged on the surface, far away from the rotating plate, of the light-emitting plate; an LED lamp for measurement is arranged on the surface, close to the rotating plate, of the light-emitting plate; the photoresistor is arranged on the connecting plate. The endoscope for pipeline inspection has the advantages that the endoscope is well combined with a focusing device according to the characteristics of the photoresistor, the function of automatic focusing is realized, the performance is stable, the structural design is reasonable, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to detection field, specifically based on the pipe detection endoscope of photoresistance.
Background technology
Endoscope can detect crooked pipeline depths, the position that can not look at straight can be observed, interior spatial structure and state can be observed in sealed cavity, distant surveillance and operation can be realized, generally speaking technoscope detects that to apply very in industry-by-industry extensive, relate to machinery, chemical industry, automobile making, Aero-Space, the exploitation manufacture of railway engineering vehicle and haulage vehicle, the field that Maintenance and Repair etc. are different, even in the capital construction process of engineering, as the construction in bridge and tunnel, the application of industrial endoscope in maintenance, also can be found.Existing endoscope lens is that if endoscope lens focusing is focused by Hall element, camera lens needs the enough large to facilitate placement magnet of design by button or Manual mechanical focusing, so just makes lens assembly volume become large.
Summary of the invention
For solving the problem, the invention provides a kind of pipe detection endoscope based on photoresistance.
The present invention adopts following technical scheme: based on the pipe detection endoscope of photoresistance, comprise endoscopic main body, endoscopic main body front end is provided with lens assembly, luminous plaque is stuck on lens assembly, swivel plate is stuck on lens assembly, be positioned at below luminous plaque, swivel plate is connected with web joint by connecting portion, described swivel plate is provided with circular hole, described luminous plaque is provided with a circle illuminating LED lamp away from the one side of swivel plate, luminous plaque is provided with measurement LED near the one side of swivel plate, and described web joint is provided with photoresistance.
Described photoresistance is two.
Described circular hole is two, two Circularhole diameter differences, and one is maximum value circular hole, and another is minimal value circular hole.
Described photoresistance is connected with processor, and processor is connected with control module, and control module is connected with lens assembly.
Described photoresistance changes resistance according to appearing the measurement light come from maximum value circular hole or minimal value circular hole, processor converts the resistance of photoresistance to magnitude of voltage, and this magnitude of voltage is sent to control module, above-mentioned magnitude of voltage is focused to lens assembly after control module treatment and analysis.
Advantage of the present invention: the present invention well combines according to the characteristic of photoresistance and focus control, realizes the function of automatic focusing, stable performance, and reasonable in design, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is circuit theory schematic diagram of the present invention.
Embodiment
As shown in Figure 1, based on the pipe detection endoscope of photoresistance, comprise endoscopic main body 1, endoscopic main body 1 front end is provided with lens assembly 2, luminous plaque 3 is stuck on lens assembly 2, swivel plate 5 is stuck on lens assembly 2, and be positioned at below luminous plaque 3, swivel plate 5 is connected with web joint 7 by connecting portion, the diameter that swivel plate 5 is provided with two circular holes, 6, two circular holes 6 is different, and one is maximum value circular hole, another is minimal value circular hole, two extreme positions of two corresponding lens focusings of circular hole 6 difference.
Luminous plaque 3 is provided with a circle illuminating LED lamp 4 away from the one side of swivel plate 5, illuminating LED lamp 4 is for detecting with illumination, luminous plaque is provided with measurement LED near the one side of swivel plate, measure LED to come from circular hole 6 transmission, web joint is provided with two photoresistance 8, when light is come from circular hole 6 transmission, the resistance of photoresistance 8 changes.Because the transmittance of circular hole 6 is different, therefore, the resistance that photoresistance 8 receives also is different, according to the resistance of photoresistance 8, can obtain lens focusing and be in very big limit position or minimum limit position.
Photoresistance is connected with processor, processor is connected with control module, control module is connected with lens assembly, photoresistance changes resistance according to appearing the measurement light come from maximum value circular hole or minimal value circular hole, processor converts the resistance of photoresistance to magnitude of voltage, and this magnitude of voltage is sent to control module, above-mentioned magnitude of voltage is focused to lens assembly after control module treatment and analysis.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
