Technical field
The utility model belongs to technology of instrument and meter field more particularly to a kind of electromagnetic type solum settlement measuring device.
Background technology
In engineering safety detection field, the observation of the settling amount of building is measured, traditional method is using electromagnetism
Formula sedimentometer is by manually being operated.Settlement gauge is the principle based on electromagnetic induction, in the different elevation locations of building
Settlement monitoring point is placed, i.e., magnet ring is sleeved on sedimentation pipe, and when settling probe detection to settlement point position, buzzer sends out sound
Sound, far from settlement point when, sound disappear.During buzzer sounding, operating personnel are first sound using by way of subjective determination
Determine position, the method estimated later by eyes reads the corresponding position of settlement point in measurement ruler and records data.It was operated
Cheng Wei：First by probe placement to nozzle, the depth of sedimentation pipe is differed from tens of rice to hundreds of meters.Then it is pulled by operating personnel
Measurement ruler dragging probe slowly falls, and when encountering magnet ring during probe falls, buzzer can make a sound, at this time operator
Member's eyes are observed and record the scale in measurement ruler.One engineering usually has multiple settlement observation holes, such repeated several times, directly
To the entire measurement process of completion.Traditional settlement gauge test method, the subjectivity error that human factor is brought is larger, main to collect
In in following problem：1：It is inaccurate there are reading using artificial reading during reading；2：When probe detection is to magnet ring position,
It moves up and down due to manually pulling measurement ruler and by acoustic fix ranging is listened to put, can not precisely determine magnet ring position, it is easy to occur
Error within 10mm；3：Measurement ruler is used from aperture fixed position reading, but aperture will appear inclination and sedimentation in Practical Project
Protuberance deformation, from the position measurement, there are errors.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of electromagnetic type solum settlement surveys of high certainty of measurement
Measure device.
In order to solve the above technical problems, electromagnetic type solum settlement measuring device provided by the utility model, including stent,
Microprocessor, signal cable, sedimentation are popped one's head in, and are fixed with resistor disc on the signal cable, cunning is fixed on the stent
Dynamic connector, the signal cable are pierced by out of described slip joint and are connected with sedimentation probe, the slip joint and the electricity
Piece sliding contact is hindered, the microprocessor is electrically connected to form closure by the tail end and slip joint of conducting wire and signal cable respectively
Circuit is equipped with electromagnetic switch on the closed circuit, and when signal cable slides in the slip joint, the slip connects
Head is in close contact always with the resistor disc, and the microprocessor can receive to settle feedback signal control of the probe detection to magnet ring
Electromagnetic switch processed disconnects, and at the same time microprocessor is calculated, preserves and shown according to the variation of resistance value in closed circuit automatically
The corresponding descending depth of sedimentation probe.
Further, the stent for adjustable support and which is provided with scalable Sopwith staff and level(l)ing bubble.
Further, the stent be adjustable for height A-frame, the A-frame top be horizontal checkout platform, institute
Scalable Sopwith staff, level(l)ing bubble and slip joint is stated to be mounted on the horizontal checkout platform.
Further, the signal cable is wrapped on wire spool.
Further, power supply and total control switch are come in the microprocessor.
Compared with prior art, for traditional measurement there are the problem of, the utility model correspondence propose a solution：It is based on
Slide rheostat principle is converted into the variation of resistance in closed circuit by that will settle probe fall depth, when sedimentation probe is visited
When measuring magnet ring, sedimentation probe detection to magnet ring position sends out feedback signal, and microprocessor controls the disconnection of electromagnetic switch, micro-
Processor reading preserves cable depth when circuit disconnects, i.e., when probe detection is to magnet ring, function is preserved using microprocessor.It is sliding
Artificial reading can be improved to processor and data are read from circuit variation by dynamic rheostat principle, solved artificial naked eyes reading and asked
Topic；The setting of magnetic switch so that settle probe detection disconnects switch to feedback signal is sent out during magnet ring position at once, micro- at this time
Data when processor records this solve the problems, such as that artificially there are errors with sound estimation magnet ring position is listened；Horizon adjustable stent
Setting settlement measurement datum mark can be made to be determined in the form of absolute elevation, solve traditional approach using aperture as datum mark without
Method considers the problems of that orifice position moves.
