When big depth (being greater than 50 meters of depth of waters), then using traditional tension sensor be it is of problems, need to be improved.In air
Tension sensor need to solve two large problems: one, how to carry out watertight under water and do not influence dynamometry.Two, how water is eliminated
Press the influence to tension sensor primary stress.
Application No. is the patents of CN201520875098.5 to disclose a kind of underwater tension sensor, including box-shaped sensor
Seal box, drawing/pressure sensor, fixed link, pull rod, watertight cable socket and cable, compensator；Drawing/pressure sensor passes through
Fixed link is fixedly mounted in sensor seal box；One panel of the sensor seal box is equipped with seal sleeve, sealing
One or more annular seal grooves are offered in sleeve, sealing ring is placed in annular seal groove, and drag link sleeve is mounted in seal sleeve
It is interior, it is sealed between pull rod and seal sleeve by sealing ring；One end of pull rod is connect with drawing/pressure sensor, the other end and drawing
Power measures force transferring part connection；Watertight cable socket is mounted on sensor sealing box panel, passes through cable and drawing/pressure sensing
Device connection；Full of insulation oil liquid in compensator and sensor seal box, compensator is connect by oil pipe with sensor seal box.It should
The structure of patent is complex, and the practicability for testing pulling force under water is lower.
Utility model content
The purpose of this utility model is the deficiency for current techniques, proposes a kind of compact structure, and be able to satisfy different water
Buckling, the underwater tension measuring device of autobalance hydraulic pressure.
The technical solution of the utility model is as follows: a kind of underwater tension measuring device, the measuring device include capsul
Body 1, foil gauge 2, end socket 3, bearing cable head 4 and sealing axis 5, the inner cavity side of the seal casinghousing 1 is close to foil gauge 2, separately
Side is equipped with end socket 3, filled with filling oil 7 inside seal casinghousing 1, and carries out vacuumize process, then is carried out by sealing axis 5 radial close
Envelope connection, the bearing cable head 4 are connected to the core wire of foil gauge 2, and 4 inside of bearing cable head is connected with end socket 3.
Preferably, the right end of the seal casinghousing 1 has one section of external screw thread 9, for the fixed article for needing to test pulling force.
Preferably, be equipped between the end socket 3 and seal casinghousing 1 and between end socket 3 and bearing cable head 4 O-ring 8 into
Row sealing.
Preferably, the 5 outside providing holes of sealing axis is limited with retaining ring 6.
The working principle of the utility model is as follows: the underwater tension measuring device is mainly by seal casinghousing, foil gauge, envelope
Head, bearing cable head, sealing axis, hole retaining ring, filling oil and O-ring composition.The inner cavity of seal casinghousing close to foil gauge, in order to
Guarantee its measurement accuracy and intensity, the wall thickness of seal casinghousing should be maintained at reasonable range.The right end of seal casinghousing is equipped with one section
External screw thread facilitates the fixed article for needing to test pulling force.It is sealed between seal casinghousing and end socket by O-ring, is connected on end socket
Bearing cable head.Filled with filling oil inside seal casinghousing, and vacuumize process is carried out, then radial seal company is carried out by sealing axis
It connects.This is the key that guarantee underwater tension sensor when different water depth works normally.Due to internal filling oil and outside
Water is isolated by radial sealing axis, is sealed, and when the depth of water increases, sealing axis can generate certain displacement, guarantees external and internal pressure
Balance avoids the deformation that seal casinghousing is acted on by hydraulic pressure at patch foil gauge in this way.To ensure that underwater tension sensor
In any depth of water, pulling force is zero at the beginning.Sealing axis drops out in order to prevent, and providing holes is limited with retaining ring on the outside of sealing axis
Position.
Load-bearing watertight connector is connected with end socket, and load-bearing watertight connector is connected to the core wire of foil gauge.When the seal casinghousing right side
When end stress causes foil gauge to deform, electric signal will be conveyed to load-bearing watertight connector, so that signal be spread out of.In addition load-bearing electricity
The transmission that cable end (load-bearing watertight connector) both ensure that signal, in turn ensures the transmitting of power.
Compared with prior art, the utility model has the following beneficial effects: the utility model compact structure, user
Just, underwater tension sensor is brought into the deformation of shell by water depth ratio and causes to survey the inaccurate ingenious solution of problem of pulling force, adopted
With oil is filled in seal cavity, reaches external and internal pressure and constantly balance, and shell will not deform；The present invention using O-ring into
Row sealing, guarantees the sealing effect of underwater tension sensor.
