Description
Technical field
The invention belongs to technology of instrument and meter field, more particularly to a kind of electromagnetic type solum settlement measurement apparatus.
Background technology
In engineering safety detection field, the observation to the settling amount of building measures, and traditional method is to use 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 sound
Sound, away from settlement point when, sound disappear.During buzzer sounding, operating personnel are first by way of sound uses subjective determination
Position is determined, the method estimated afterwards by eyes, reads and surveys position corresponding to settlement point and record data on chi.It was operated
Cheng Wei：First by probe placement to the mouth of pipe, the depth of sedimentation pipe is from tens of rice to hundreds of meters.Then pulled by operating personnel
Survey chi and drag probe slowly whereabouts, when running into magnet ring during whereabouts of popping one's head in, buzzer can send sound, now operator
The scale surveyed on chi is observed and recorded to member's eyes.One engineering generally has multiple settlement observation holes, such repeated several times, directly
To the whole measurement process of completion.Traditional settlement gauge method of testing, the subjectivity error that human factor is brought is larger, main collection
In in following problem：1：During reading, using artificial reading, it is inaccurate to there is reading；2：When probe detection is to magnet ring position,
Because the artificial survey chi that pulls moves up and down, and by listening acoustic fix ranging to put, it can not precisely determine magnet ring position, it is easy to occur
Error within 10mm；3：Survey chi to use from aperture fixed position reading, but inclination and sedimentation occurs in aperture in Practical Project
, error be present from the position measurement in protuberance deformation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of measurement accuracy high electromagnetic type solum settlement measurement dress
Put.
In order to solve the above technical problems, electromagnetic type solum settlement measurement apparatus provided by the present invention, including support, Wei Chu
Device, signal cable, sedimentation probe are managed, is fixed with resistor disc on the signal cable, being fixed with slip on the support connects
Head, the signal cable are passed out of described slip joint and connected with sedimentation probe, the slip joint and the resistor disc
Sliding contact, the microprocessor are electrically connected to form by the tail end and slip joint of wire and signal cable close back respectively
Road, electromagnetic switch is provided with the closed-loop path, when signal cable slides in the slip joint, the slip joint
All the time it is in close contact with the resistor disc, the feedback signal that the microprocessor can receive to settle probe detection to magnet ring controls
Electromagnetic switch is disconnected, and at the same time microprocessor is calculated, preserves and shown according to the change of resistance value in closed-loop path and be heavy automatically
Descending depth corresponding to drop probe.
Further, the support is adjustable support and which is provided with scalable Sopwith staff and level(l)ing bubble.
Further, the support is adjustable for height A-frame, and the A-frame top is 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 with the microprocessor.
Compared with prior art, the problem of existing for traditional measurement, the present invention is corresponding to propose a solution：Based on slip
Rheostat principle, by the way that sedimentation probe fall depth to be converted into the change of resistance in closed-loop path, when sedimentation probe detection arrives
During magnet ring, sedimentation probe detection to magnet ring position sends feedback signal, and microprocessor controls the disconnection of electromagnetic switch, microprocessor
Device reading preserves cable depth when circuit disconnects, i.e., when probe detection is to magnet ring, function is preserved using microprocessor.Slide and become
Artificial reading can be improved to processor and data are read from circuit variation by resistance device principle, solve the problems, such as artificial naked eyes reading；Magnetic
The setting of control switch make it that settle probe detection disconnects switch to feedback signal is sent during magnet ring position at once, now microprocessor
Data when recording this, solve the problems, such as artificially with listening sound estimation magnet ring position error to be present；The setting of horizon adjustable support can
Settlement measurement datum mark is set to be determined in the form of absolute elevation, solving traditional approach can not consider by datum mark of aperture
The problem of orifice position moves.
