The simulation test device can observe the development process of the collapse accident more intuitively, which is convenient for personnel to monitor and conduct targeted inspections on the pipelines in a more preventive manner.

[0022] According to the present specific implementation manner, the test box 102 is fixedly connected to the support platform 101 and is located above the support platform 101. The test assembly includes multiple groups of seals, a water tank 103, a water pump 104, a water inlet pipe 105, an adjusting member, a water outlet pipe 106 and a collecting box 107.

The pull buckle 109 is fixedly connected to the sealing cover 108 and is located on the outside of the sealing cover 108. When the pull buckle 109 is pulled outward, the sealing cover 108 cancels the sealing of the test box 102, thereby simulating the phenomenon of pipeline damage at different positions.

When the hydraulic cylinder 113 retracts, the extension block 114 drives the arc-shaped insert pipe 115 to slide in the connecting pipe 110. Through the arc setting of the arc-shaped insert pipe 115, the process of the pipeline damage position changing from small to large is simulated, so that the simulation test results are more in line with reality, and the accuracy of the simulation effect of the test device is improved.

When it is used, simulated water is added into the water tank 103, the buckle 109 is pulled outward, the blocking cover 108 cancels the blocking of the test box 102, the water inlet pipe 105 and the water outlet pipe 106 are installed in the test box 102, the connecting pipe 110 is connected to the water inlet pipe 105, the fixed pipe 111 is connected to the water outlet pipe 106, and then the connecting pipe 110 and the fixed pipe 111 are connected by the connecting tool 112, and the hydraulic cylinder 113 drives the hydraulic cylinder 113 to drive ... The arc-shaped insert pipe 115 is inserted into the connecting pipe 110, and sand, simulated roads and vehicles, etc. are filled into the test box 102. The water pump 104 runs to simulate the water flow in the pipeline to flow in the water inlet pipe 105, and the outflowing water is introduced into the collecting box 107 through the water outlet pipe 106. The hydraulic cylinder 113 retracts, and the extension block 114 drives the arc-shaped insert pipe 115 to slide in the connecting pipe 110. The arc-shaped setting of the arc-shaped insert pipe 115 simulates the process of the damaged position of the pipeline changing from small to large, thereby simulating the damage process of the pipeline leakage point changing from small to large, so that the simulation test result is closer to reality.
