Hydraulic model test teaching platform

Abstract

The invention discloses a hydraulic model test teaching platform, which comprises a frame, a simulated dam body, a main driving mechanism and a pressure sensor, and a horizontal guide sleeve is fixed on the frame front side of the frame directly opposite to the simulated dam body and matched with a Horizontal adjustment rod and locking mechanism; a vertical guide sleeve is vertically fixed on the horizontal adjustment rod and matched with a vertical adjustment rod and a locking mechanism; a vertical support rod or an adjustment cylinder is installed at the end of the horizontal adjustment rod , a horizontal adjustment rod or an adjustment cylinder is installed at the end of the vertical adjustment rod; a pressure sensor and a fork are respectively arranged at the end of each support rod or adjustment rod, and a support block is installed in cooperation with the fork, and the support block is provided with a rotating shaft , the rotating shaft is matched and set in the fork, and the support block is attached to the surface of the simulated dam body. The invention is flexible and convenient to assemble, the pressure support point of the simulated dam body can be adjusted arbitrarily in the three-dimensional direction, can meet the requirements of model tests of different scales, can be used for teaching demonstration, intuitively learn and understand the three-dimensional geomechanics model test, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering teaching tools, in particular to a hydraulic model test teaching platform. Background technique [0002] The 21st century is the century of rapid development of China's engineering construction. In the new century, the development of large-scale projects such as water conservancy, hydropower, energy, and transportation has become the focus of my country's economic construction. With the continuous development of the national economy and the implementation of the western development strategy, my country has ushered in the peak period of large-scale engineering construction, such as the Three Gorges, Longtan, Xiluodu, South-to-North Water Diversion and other large-scale water conservancy and hydropower projects; Large-scale energy projects such as power-to-east transmission; large-scale transportation projects such as the Qinghai-Tibet Railway, Shanghai-Chengdu Expressway, and large-sca...

Problems solved by technology

[0004] The general problems of the above-mentioned test bench devices are: (1) The size of the test bench device is fixed and cannot be adjusted effectively according to the model test range; (2) The test bench devices are mostly welded with section steel, and the structure is mostly plate beam or The frame-beam structure is the main type. Under the action of lateral pressure, the lateral deflection and deformation of the bench are usually large, which may easily cause changes in the test boundary conditions.
