Abstract
The utility model relates to a laboratory water-sand interface topographic surveying device, mainly comprising a moving carriage, a track, a stepping motor, a light intensity measuring device, and a controller. An elevating stepping motor and a guide sleeve are fixed to the moving carriage, a guide bar can glide in the guide sleeve up and down, the elevating stepping motor is connected with the top of the guide bar through a guy rope, the bottom of the guide bar is provided with the light intensity measuring device, and the moving carriage can run on a transversal track to realize the plane motion. The light intensity measuring device moves lengthways on the moving carriage following the guide bar and tests the position of the interface to finish the water-sand interface topographic survey and then to ascertain the variation of the washed silt of the topographic interface by measuring the topography before and after washed.
Description
Technical field:
The utility model belongs to the husky interface of a kind of novel water topographical surveying device in the water conservancy project laboratory.
Technical background:
Although there are many difficulties in physical simulation in theory with on the test design, but confirmation is the reliable research means near engineering reality in practice, especially aspect the preferred and contrast of local engineering, have the incomparable advantage of other research methods, and logarithmic mode research also can be played the checking effect.This also is many-sided PHYSICAL MODELING OF IN is all carried out in the large-scale harbor work in countries in the world, water conservancy project construction in the laboratory a major reason.
The water conservancy project laboratory need make foundation model when the migration of research silt, seafloor scour, the landform of testing under the various operating mode effects changes.In the laboratory, mainly measure water sand interface landform at present by setting in advance reference point or application underwater ultrasound Topographical indicator.The point that sets in advance the measurement of reference point method is limited, and measuring accuracy is not high yet.The measurement effect of underwater ultrasound Topographical indicator is better, but very weak at the reflected signal that local landform acute variation place receives, perhaps can not receive reflected signal, cause serious measuring error, be difficult to again when data analysis judge that this has influenced the measuring accuracy of the husky interface of water landform to a certain extent.
Summary of the invention:
The utility model is studied a kind of novel laboratory Topographical indicator, improves the measuring accuracy of the husky interface of water landform, and the purpose of this utility model is a kind of husky interface of breadboard water topographical surveying device that is used for of exploitation.
A kind of husky interface of breadboard water topographical surveying device that is used for, by running trolley, track, stepper motor, the light intensity tester, compositions such as controller, the lifting stepper motor, orienting sleeve, controller is fixed on the running trolley, horizontal stepper motor is connected with running trolley by thin steel rope, guide pole can slide up and down in orienting sleeve, the lifting stepper motor connects the guide pole top by stay cord, the light intensity tester is installed in the guide pole bottom, running trolley is installed in and has wheel, fixed pulley, on the cross track of horizontal stepper motor, wheel is installed on the long rails, controller is connected with an end of control line, thin steel rope is walked around fixed pulley, two ends are consolidated on the running trolley behind the horizontal stepper motor, the lifting stepper motor, horizontal stepper motor, connect by control line respectively between light intensity tester and the controller.
Cross track moves on long rails, and running trolley moves on cross track, and running trolley can be realized the plane fixed point motion like this; The light intensity tester is made catenary motion with guide pole on running trolley, and according to the penetrating light intensity scope test interface position that sets in advance, finishes the measurement of the husky interface of water landform relative height; Dash the silt variable quantity by what the landform of measurement before and after washing away can be determined the landform interface.Controller is according to the plane motion of the programmed control running trolley of setting and the catenary motion of light intensity tester, measuring process intellectuality.
In the measuring process, light intensity tester direct contact water sand ground shape interface differentiates whether arrived water sand ground shape interface according to penetrating light intensity, and the terrain slope size does not influence measuring accuracy, so the measuring accuracy of the husky interface of water landform improves.

Embodiment:
Now, the utility model is further described in conjunction with Figure of description:
Make running trolley 2, orienting sleeve 1, guide pole 8, cross track 3, long rails 5 etc. according to designing requirement; Wheel 4, fixed pulley 6, horizontal stepper motor 14 are installed on the cross track 3; Wheel 4 is positioned on the long rails 5; Running trolley 2 is installed on the cross track 3; Lifting stepper motor 10 and orienting sleeve 1 are fixed on the running trolley 2; Guide pole 8 is penetrated in the orienting sleeve 1 from bottom to top, and lifting stepper motor 10 connects guide pole 8 tops by stay cord 12; Light intensity tester 9 is installed in guide pole 8 bottoms; Thin steel rope 7 is walked around fixed pulley 6, two ends, horizontal stepper motor 14 back are consolidated on the running trolley 2; Controller 13 is installed on the running trolley 2; Connect by control line 11 respectively between lifting stepper motor 10, horizontal stepper motor 14, light intensity tester 9 and the controller 13.
The husky interface of water is during topographical surveying, cross track 3 moves on long rails 5 and once arrives assigned address, running trolley 2 is moving linearly on cross track 3, arrive measuring point time strength tester 9 and on running trolley 2, do motion vertically downward with guide pole 8, at any time measure penetrating light intensity, and according to the penetrating light intensity scope affirmation interface location that sets in advance, light intensity tester 9 moves vertically upward on running trolley 2 with guide pole 8 and stops at and limits the position behind the arrival interface location, finishes the measurement of the husky interface of the water landform relative height of this point; Then, running trolley 2 moving linearlies arrive other measuring point and measure; After the straight line point measurement was finished, the measurement of another rectilinear point was carried out in cross track 3 other position of reruning on long rails 5; So repeatedly, finish regional interface topographical surveying.
Controller 13 is controlled the plane motion of running trolley 2 and the catenary motion of light intensity tester 9, the measuring process intellectuality according to the program of setting.
In the measuring process, light intensity tester 9 direct contact water sand ground shape interfaces differentiate whether arrived water sand ground shape interface according to penetrating light intensity, and the terrain slope size can not influence measuring accuracy, so the measuring accuracy of the husky interface of water landform improves.
This device is applicable to the husky interface of the indoor water of experiments of measuring landform.In addition, dash the silt variable quantity by what the landform of measurement before and after washing away can be calculated the husky interface of water.
