Description
Described technical field
The utility model provides a kind of bench drill formula ice layer thickness measurement mechanism, belongs to ice layer thickness surveying instrument technical field.
Background technology
At present, the method for measuring ice layer thickness both at home and abroad roughly comprises:
1. the electromagnetic wave of dependence emission, sound wave etc. penetrate ice sheet, go out the thickness of ice sheet with its time conversion that turns back to receiver.But because the character of ice is more special, its physical parameter changes in certain scope with ambient temperature, this has just caused to measure and has had bigger error, and as being mixed with a large amount of silt and impurity in the Huanghe water, this error that makes this method bring is more uncertain.
2. rely on emission ultrasound wave and laser to arrive the ice sheet interface, go out distance according to the Time Calculation that reflects apart from the interface, but the measured precision of this method is subjected to the influence that local surfaces rises and falls, and the measurement of thickness need just can obtain on ice sheet surface and bottom surface relative measurement, and operation is very inconvenient.
3. directly borehole survey, the method is simple and reliable, but needs strong physical work.When on the Yellow River, measuring ice layer thickness at present, use cold chisel that the ice sheet cutter is saturating, directly measure with ruler then.
In sum, the at present no matter domestic high-precision survey instrument that still still is fit to measure the practicality of the Yellow River ice layer thickness in the world.In view of the use cold chisel cutter of present employing is worn the method that ice sheet is measured ice layer thickness, not only waste a large amount of muscle power, efficiency of measurement and measuring accuracy are all very low, and cause the ice surface large area to destroy easily, bring life danger to engineering technical personnel, so be badly in need of a kind of accurate, simple to operate, safe and reliable ice layer thickness surveying instrument of measuring.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, measure accurate, simple to operate, safe and reliable bench drill formula ice layer thickness measurement mechanism.Its technology contents is:
A kind of bench drill formula ice layer thickness measurement mechanism, it is characterized in that: comprise support, be fixed on the casing of cantilever tip, guide, vertical feed mechanism, signals collecting mechanism and drill bit, wherein drill bit is vertically fixed on the bottom of vertical feed mechanism, signals collecting mechanism comprises pulley blocks, signal gear and photoelectric sensor, wherein top sheave is installed on the upper end inwall of guide and is positioned at vertical feed mechanism top, lower sheave and signal gear be coaxial to be installed on the cabinet wall of guide bottom, be connected in, nothing between the lower sheave rope that stretches, the one side is fixedlyed connected with vertical feed mechanism, photoelectric sensor is positioned at a side of signal gear, and its signal output part connects single-chip microcomputer.
Described bench drill formula ice layer thickness measurement mechanism, vertical feed mechanism comprises splined shaft, be sleeved on the splined shaft top and with the thrust bearing of its interference fit, be fastened on the slide block on thrust bearing top, be embedded on the inwall of slide block lower end and the circlip that contacts with the thrust bearing lower surface, the handle that is connected with the slide block horizontal fixed, the follower gear that is connected with the splined shaft spline and be installed in the casing driving gear that meshes by the motor-driven and the driven tooth gear teeth, the guide both sides vertically have groove, handle leans out from groove and can slide up and down in groove, and the rope of pulley one side is fixedlyed connected with slide block.
Described bench drill formula ice layer thickness measurement mechanism, handle is threaded with slide block.
Described bench drill formula ice layer thickness measurement mechanism, follower gear is installed in the lower end of splined shaft.
Described bench drill formula ice layer thickness measurement mechanism, the bottom of support is provided with pilot hole in the vertical lower that is positioned at drill bit.
Its principle of work is: support is placed on the ice face during measurement, and drill bit is done to move vertically downward to pierce ice sheet by the vertical feed mechanism controls during measurement, and starting point is the ice face, and terminating point is the water surface, and drill stroke is the thickness of ice sheet.Do not have one side of flexible rope and fix with vertical feed mechanism, it is moved with vertical feed mechanism, thereby drive upper and lower pulley rotation, lower sheave drives signal gear and rotates, and finishes signals collecting by sensor, outputs to single-chip microcomputer and carries out signal Processing.Water just is to exist form with ice maximum different on physical property, so drill bit brill open ice the layer moment have very big velocity variations, this measurement mechanism makes full use of this point just, will touch water spot and judge, again according to this moment drill stroke obtain ice layer thickness.
The utility model compared with prior art, utilize direct boring method to measure ice layer thickness, this device solves because of the character temperature influence influence that causes the uncertain factor in the physical measurement techniques to bring of ice, eliminate the measuring error that this influence brought, and be more suitable for the high concentration of sediment as the Yellow River and the measurement of dirty ice layer thickness.This has just thoroughly eliminated the influence of skidding and being brought in measuring process and irrelevant with the rotation of drill bit because the rotation of signal gear is only relevant with drill stroke, makes measurement more accurate.The utility model comes out people's thorough liberation from heavy manual labor such as make a hole in the ice, and has easy to carryly, simple to operate, measures advantages such as accurate.
