Description
Technical field
The utility model relates to a kind of defect detection on ultrasonic basis of medium plate that is applicable to and hinders device with control, belongs to technical field of nondestructive testing.
Background technology
Existing steel plate inspection method is divided into by the ultrasound wave coupling scheme: single normal probe contact method and local water logging defectoscopy.The common problem that exists of these two kinds of methods is: labour intensity is big, high material consumption, and accuracy rate is low.Adopt single normal probe contact method to carry out dark triage and survey, 300 yuan of homemade probes can only detect several planks, and probe just is worn bad, the wearing and tearing especially severe.In addition, existing flaw detection mode inefficiency is influenced greatly by the surface of steel plate situation, during with lower steel plate, influenced by ultrasonic near field at carrying out flaw detection 160mm, and the blind area is bigger, and the flaw detection accuracy rate is low, probe serious wear, high material consumption.
The utility model content
The purpose of this utility model is to provide a kind of device of fixedly water column pulse reflection method flaw detection steel plate, so that the blind area of ultrasound wave in steel plate is as far as possible little, improves the flaw detection accuracy rate, and prolongs the serviceable life of probe.
To achieve these goals, the technical solution of the utility model has been to adopt a kind of device of fixedly water column pulse reflection method flaw detection steel plate, this device is by the slide block of bottom opening, water jacket and the interior probe of installing of water jacket fixing on the slide block constitute, described probe is fixed on the top of water jacket, water jacket lower port place is set with a slice barrier film and will be sealed into an enclosed cavity in the water jacket, be filled with water column in the enclosed cavity, water column floods probe wraps up in embedding, the probe wafer down, next door in water jacket on slide block is provided with water inlet, has one to cross water space between the bottom surface of described barrier film and the residing plane of the lower port of slide block.
Another next door in water jacket on the described slide block also is provided with a water delivering orifice.
Described water inlet, water delivering orifice are separately positioned on the left side and the right side of slide block upper surface.
Described barrier film is a plastic sheeting.
Be respectively arranged with a gudgeon on the left and right sides face of described slide block.
Adopt structure of the present utility model, on slide block, be fixed with a water jacket, probe is installed in the water jacket, probe is fixed on the top of water jacket, water jacket lower port place is set with a slice barrier film and will be sealed into an enclosed cavity in the water jacket, be filled with water column in the enclosed cavity, this water column is one section clean water column, and barrier film is kept apart water column in the water jacket and the water in the slide block; During detection, device button of the present utility model is placed on surface of steel plate to be detected, ultrasound wave passes between water column, barrier film and water jacket and the slide block moisture film that flows and enters into steel plate to be measured and carry out carrying out flaw detection, water inlet and water delivering orifice that the upper surface left and right sides of slide block is provided with have respectively guaranteed to form all the time between water jacket and the steel plate the mobile moisture film of a very thin cleaning; Structure of the present utility model makes and to remain one section fixing clean water column between probe wafer and the steel plate to be detected, make the waveform on the defectoscope screen show more directly perceived, for the second time and all be the echo of steel plate bottom surface for the third time between the ripples, just echo times changes the personnel's survey of being convenient to detect a flaw with steel plate thickness is different.Structure of the present utility model makes and has formed a cleaning, stable coupling water layer between probe and the steel plate, thereby makes the result of detection more accurate.The utility model flaw detection efficient height, flaw detection sensitivity is higher, has avoided the near field region interference, and the blind area is little, can effectively reduce the probe wearing and tearing, prolongs the serviceable life of probe.Device of the present utility model is specially adapted to the in enormous quantities carrying out flaw detection of steel plate thickness between 40mm～160mm.
