Description
Technical field
The present invention relates to a kind of carbonation depth detector that cement-based material and structure durability detect that is used for, particularly a kind ofly can amplify the detecting instrument of accurately confirming the carbonization leading edge with imaging and measuring carbonation depth through figure.
Background technology
Carbonation depth is an important indicator weighing military service concrete strength and endurance quality.Generally adopt boring method at present in engineering detecting and the existing standard; Be that electricity consumption is drilled in to detect on the thing and holes; Then with the concrete around the phenolphthalein spraying boring; Distinguish carbonization of concrete district and non-carbonizing zone, promptly find out carbonization leading edge or carbonization separatrix, measure with ruler or vernier caliper then.Less when carbonation depth, in the time of can distinguishing the carbonization leading edge with sight, this kind method is comparatively feasible.But it is bigger to work as concrete carbonization depth; Comparatively serious like the on-site concrete carbonization; Particularly do not allow when destroying concrete component in the laboratory study carbonization of concrete degree of depth; Be difficult to or when being not sure of the boundary of carbonizing zone and non-carbonizing zone, said method is difficult to obtain carbonation depth value accurately with sight, this makes resilience confirm that concrete strength and endurance quality index are very inaccurate.
At present, existing chi formula, the pen type carbonation depth of measuring concrete carbonization depth measured patent, and it fathoms less than 10mm, can not satisfy the bigger concrete component of carbonation depth and measure; Vernier caliper formula and electric drill add slide calliper rule formula carbonation depth and measure patent; Though precision with fathom on increase, measuring principle is with chi formula and pen type carbonation depth measuring instrument, mainly still relies on the boundary that sight is distinguished carbonizing zone and non-carbonizing zone; When carbonation depth is big; The sight of stravismus is difficult to this boundary of location, and light is relatively poor in this moment hole, and it is difficult more that the carbonization leading edge is confirmed.Utilize present instrument that the bigger cement-based material member of carbonation depth is accurately measured, have only member is destroyed, but this is unallowed in the component test of actual engineering or some testing laboratory.
Summary of the invention
In order to solve the above-mentioned deficiency in the present cement-based material carbonation depth measurement; The present invention provides a kind of carbonation depth detector; The present invention can accurately confirm carbonizing zone and non-carbonizing zone and measure carbonation depth that suitable carbonation depth measurement range is bigger through figure amplification and imaging.
The technical solution adopted for the present invention to solve the technical problems is: a kind of carbonation depth detector comprises: survey chi, microlens, lighting source, camera, tool housing, survey ruler end part protrusion, precision gear, signal cable and power cable, IMAQ and process chip, video display, the roller that has spring, power switch, power work pilot lamp, diode and camera supply module, image collection chip and video display supply module; Wherein, Survey chi and pass tool housing; Survey ruler end part protrusion, lighting source, microlens and camera and be fixed on and survey the chi front end; Survey the engagement of chi and precision gear, the camera through signal wire cable links to each other with process chip with IMAQ with power cable, and IMAQ links to each other with video display with process chip.The roller that has spring is fixed in the tool housing; Signal cable and power cable are walked around the roller that has spring; Power switch and power work pilot lamp are fixed on the tool housing outside surface; Diode links to each other with camera with lighting source with the camera supply module, and image collection chip links to each other with video display with process chip with IMAQ with the video display supply module.
The invention has the beneficial effects as follows: image of the present invention amplifies with image-forming module can present the concrete color situation of change after phenolphthalein sprays clear, truly; Can accurately find out the carbonization separatrix through the images displayed video, avoid looking side ways the error that range estimation brings.The light emitting diode that is positioned at optical lens or microlens both sides can make institute's image of adopting more clear, eliminates the influence of deep hole insufficient light, range estimation difficulty.The depth survey scope that this instrument was suitable for is bigger, not only can be applicable to the scene but also can be applicable to testing laboratory's carbonation depth detection.The vertical weaving done in fine silks and gold thread by the tapestry method of microlens both had been used for confirming the carbonization boundary, was used as the zero point of surveying chi again, when vertical weaving done in fine silks and gold thread by the tapestry method image overlaps with the carbonization leading edge, read the data of surveying chi the right and was carbonation depth, and reading is direct, conveniently.Measure quick, simple to operate.
