Description

Sliding intelligent inclinometer

Technical field

What the present invention relates to is a kind of sliding intelligent inclinometer that uses in the rock soil mass inner inclination deformation measurement of projects such as Geotechnical Engineering such as high slope, high embankment, deep basal pit, soft base, underground power house, belongs to dynamo-electric, Computer Applied Technology field.

Background technology

In projects such as Geotechnical Engineering high slope, high embankment, deep basal pit, soft base, underground power house, ground or country rock inside soil body can be because upper load effect run-off the straight distortion or lateral deformations, dynamically guarantee engineering safety in time grasping inclination and distortion, generally will carry out inclination and distortion or lateral deformation dynamic monitoring work.

The ultimate principle of deviational survey is, measuring sonde extend into the gaging hole deep of presetting, and the one-point measurement from bottom to top fixedly inclination angle of section changes, according to the change in displacement of section length calculated level direction, totally obtain the aggregate level displacement of position, aperture from bottom to top, as shown in Figure 2.

The conventional method that adopts is at present, and probe is connected on the cable, manually lifts cable and drives the location survey from bottom to top of popping one's head in.The manual method measurement has that labour intensity is big, probe positioning error, cable strand around etc. shortcoming.Especially for the deep hole greater than 50m, cable adds the probe oeverall quality and increases, and can produce bigger positioning error, in addition, because cable is long, manually lifts cable and can produce more serious strand around phenomenon, cause the signal conductor in the cable damaged easily so that short circuit causes system failure to measure.

Summary of the invention

The objective of the invention is to defective at above-mentioned existence, propose a kind ofly can to overcome effectively that the manpower labour intensity that prior art exists is big, signal-transmitting cable easily strand around the sliding intelligent inclinometer of defectives such as, measuring error is big.

Technical solution of the present invention: it is characterized in that by reception, data processing controller, winder, data acquisition, mission controller three parts are formed, wherein the measurement controller in reception, the data processing controller joins by the control panel in control line and the winder, signal cable in the winder joins by the measuring sonde in length metering meter and data acquisition, the mission controller, and the data acquisition transmitter in data acquisition, the mission controller is given by wireless transmit and received, the data wireless receiver in the data processing controller; Described winder comprises control line, control panel, drive motor, driving-belt, wire spool, signal cable, length metering meter, accumulator, wherein drive motor joins by driving-belt and wire spool, signal cable is on wire spool, and of signal cable is connected in series with length metering meter, measuring sonde; The other end of signal cable connects the data acquisition transmitter, and control line and drive motor join; Every the regular length setting identification, length metering is by the control of label detection sensor on signal cable for described length metering meter, and when detecting sign, control system is sent the instruction that stops to promote, and suspends predetermined distance and continues after the time to promote; Establish the automatic spacing switch between length metering meter and measuring sonde: in the porch of winder, an elastic steel sheet that has semicircle orifice is arranged, the size in hole allows signal cable to pass through, but measuring sonde can't pass through; When measuring sonde upwards withstands elastic steel sheet, the travel switch action, motor stops upwards to rotate, and all control signals that make progress lost efficacy, and at this moment motor moves downward, and when probe breaks away from elastic steel sheet, can recover control upwards.

Advantage of the present invention: have the lifting of automatic realization probe, fixed point, measurement, recording process function; Compared with prior art, have the saving manpower, raise the efficiency, accurate positioning, data stabilization, precision height, measuring speed is fast, operating process is simple, the signal conductor in the cable does not have strand around characteristics such as, the degree of wear is low.In addition, little, the light weight of instrument volume can realize single carrying, installs, carries, measure.

Embodiment

The contrast accompanying drawing, its structure is by reception, data processing controller, winder, data acquisition, mission controller three parts are formed, wherein the measurement controller 1 in reception, the data processing controller joins by the control panel 5 in control line 4 and the winder, signal cable 9 in the winder joins by the measuring sonde 12 in length metering meter and data acquisition, the mission controller, and the data acquisition transmitter 13 in data acquisition, the mission controller is given by wireless transmit and received, the data wireless receiver 2 in the data processing controller.

Described reception, data processing controller comprise measures controller 1, data wireless receiver 2, data-carrier store 3.

Described winder comprises control line 4, control panel 5, drive motor 6, driving-belt 7, wire spool 8, signal cable 9, length metering meter 10, accumulator 11.Wherein drive motor 6 joins by driving-belt 7 and wire spool 8, and signal cable 9 is on wire spool 8, and of signal cable 9 is connected in series with length metering meter 10, measuring sonde 12; The other end of signal cable 9 connects data acquisition transmitter 13, and control line 4 joins with drive motor 6.

Described data acquisition, mission controller comprise measuring sonde 12, data acquisition transmitter 13, join by signal cable 9 between them.

During work, winder divides electronic and automatic, is electronic mode with driven by motor winder scrolling cable, and also directly manual turntable is a manual mode.Use will pull up the pin on the wheel disc axle to revolve when manual to turn 90 degrees, motor just throws off to come, manually effectively; Use when electronic, pin is gone back to 90 degree it is resetted, motor is even connect, electronic effectively.

Data acquisition transmitter 13 provides measuring sonde 12 working powers, and the gradient conversion of signals is become digital quantity, emits with radio signal then, and data acquisition transmitter 13 uses the 9V battery.An antenna is arranged on the data acquisition transmitter 13, will extract suitable length during use, and it is supported on the special-purpose support.
