Pit shaft corrosion supersonic reflectoscope is to be specifically designed to the checkout equipment that detects in-service gas storage well corrosion condition.During detection, filled with water in gas storage well bore, the degree of depth that gauge head may be surveyed surpasses 300 meters, so water-tight is concerning gauge head and important.Existing pit shaft corrosion supersonic reflectoscope adopts multi-channel detection, the connector of instrument and probe is comprised of multi-pin connector, multiple signals line and probe joint, the multiple signals line is cast in the gauge head body of rod, and multi-pin connector adopts the mode that is flexible coupling to pop one's head in and be connected with gauge head with instrument in gauge head respectively outward with the probe joint.Because the segment signal line be connected with the probe joint is outside exposed, so that prevent that water under high pressure from entering gauge head inside, just need to use enough pouring length can reach waterproof effect.On the other hand, each probe joint independently plugs, and this for probe, safeguards and replacing brings inconvenience, also is unfavorable for the waterproof of probe simultaneously.
The utility model content:
For improving above the deficiencies in the prior art, the utility model proposes a kind of water-proof connector for the pit shaft ultrasonic measurement, realize that with gauge head outer ultrasonic probe plug-in is connected with instrument in gauge head.
The purpose of this utility model is achieved through the following technical solutions:
The utility model provides a kind of water-proof connector for the pit shaft ultrasonic measurement, for connecting pit shaft ultrasound measuring instrument and probe, described connector comprises the connection body, connects the circular circuit board of instrument and probe combination hub annular circuit board, and the circular circuit board of described connection instrument and the combination hub annular circuit board of popping one's head in lay respectively at the two ends of described connection body;
Further, the circular circuit board of described connection instrument is arranged on the connector circular cavity outside that connects an end in body; Described probe combination hub annular circuit board is arranged on the outside, connector annular chamber that connects the other end in body;
Further, the multiple signals line is through the holding wire via hole in described connection body, and an end is welded on the socket connected on the circular circuit board of instrument, and the other end is welded on described probe combination hub annular circuit board;
Further, the described probe combination hub annular circuit board outside is stained with knot probe combination hub annular circuit board protection plate with fluid sealant;
Further, be provided with waterproof O shape ring recess on the shell of described connection body one end and connect instrument end external screw thread;
Further, in the middle of described connection body annular chamber be the connection sound end extension rod for fixing described probe;
Further, described probe is inserted on the connection probe socket on probe combination hub annular circuit board;
Further, described probe is annular contact pin type probe;
Further, also have a plurality of annular circuit board hole for injecting glue on described probe combination hub annular circuit board.
The utility model has the advantage of: this pit shaft ultrasound measuring instrument can realize that with gauge head outer ultrasonic probe plug-in is connected with instrument in gauge head with the probe water-proof connector, convenient and reliable; The connector volume reduces simultaneously, the good water-proof effect be connected with probe.
