Fluid-solid coupled model test water level automatic control system

Abstract

The invention discloses a fluid-solid coupling model test water level automatic control system which comprises a water level monitor, a controller, a water replenishing device and a real-time display device; the water level monitor, the water replenishing device and the real-time display device are all connected with the controller; the water level monitor comprises a floating scale and a grating scale displacement sensor; the floating scale is connected with the readout end of the grating scale displacement sensor; the readout end is driven to move through scale floating; the pulse signal of the grating scale displacement sensor reflects the height of water level; the controller controls the water replenishing device to adjust the water level by collecting the data signal of the water level monitor. The fluid-solid coupling model test water level automatic control system provided by the invention has the benefits as follows: the system can be used for monitoring, regulating and controlling the water level in real time, so as to ensure the authenticity and the accuracy of testing results; full automation is achieved, and labor input in tests are reduced.

Description

Technical field [0001] The invention relates to a model test device, in particular to a water level automatic control system in geomechanics model test. Background technique [0002] With the development of my country’s economy and science and technology, submarine tunnels that cross faults, river-crossing tunnels and deep-buried large-section tunnels in karst areas are becoming more and more common in transportation construction. The impact of water on the successful construction of these projects is also very significant. Many technical problems need to be solved urgently. Many experts hope to simulate on-site working conditions through model tests and draw conclusions to guide the safe and smooth progress of on-site construction. [0003] In the fluid-solid coupling model test, the top water storage is often used for water pressure loading, and the hydrostatic pressure is adjusted by controlling the water surface height to meet the test's requirements for water pressure. In the...

Problems solved by technology

In the traditional model test technology, manual observation is mainly used, and the water level is adjusted by manually opening and closing the faucet, which is time-consuming and labor-intensive, and the efficiency and degree of automation are relatively low.
