Automatic measuring device of three-dimensional terrain of water tank

Abstract

The invention discloses an automatic measuring device of the three-dimensional terrain of a water tank, comprising a travel carriage system in which wheels are arranged on the track on the top surface of the side wall of the water tank, a fracture surface terrain measuring hackle and an automatic control and identification system, wherein the fracture surface terrain measuring hackle comprises a support panel connected on the travel carriage system, a scale panel which is connected with the side wall of the support panel and provided with scale lines thereon, an electric magnet which is arranged on the top of the scale panel, and guide bars which are arranged below the support panel and internally provided with guide holes; each guide hole is internally inserted with a measuring needle; the top of the measuring needle is provided with a measuring needle cap; the travel carriage system comprises a stepping motor which is connected with wheels through a transmission device; the steppingmotor and the electric magnet are respectively connected with a control switch; and the automatic control and identification system comprises a computer and a camera which is arranged opposite to thescale panel. The adoption of the device greatly reduces the complexity of the technology and greatly shortens the time required by measuring the three-dimensional terrain.

Description

technical field [0001] The invention relates to the technical field of physical model tests of water conservancy projects, in particular to a fast, automatic and intelligent measuring device for three-dimensional topography formed by a moving bed test in a water tank. Background technique [0002] At present, the dynamic bed physical model test (that is, the use of model sand to simulate the evolution of the natural river bed) has been widely used in the field of hydraulic engineering research. Researchers can quantitatively analyze the sand slope at the bottom of the river by measuring the topographic evolution of the indoor flume model. Movement, spur dam or river bed erosion and siltation near bridge piers, etc. The topography measurement in the tank is one of the key points in the physical model test of the moving bed. [0003] The traditional topographic measurement of flume is realized by stylus. The stylus is usually installed on the measuring trolley. After the sty...
