Abstract: Embodiments of the present disclosure provide a displacement device, comprising a plate model, a cylinder, a circulation component, a confining pressure pump, a displacement component, an acoustic detection component, and a pipeline component. The plate model includes a model cavity and a rock plate disposed in the model cavity, and the rock plate is provided with a sealing member on a surface. The sealing member is provided with an electrode sheet, and acoustic waves generated by the acoustic detection component pass through the rock plate and are received by an acoustic reception assembly. The confining pressure pump applies a confining pressure on the plate model. The pipeline component includes an inner pipeline and an outer pipeline, and a fluid is provided between the outer and the inner pipelines. Cables of the acoustic detection component are provided inside the inner pipeline and are connected to the outside through the inner pipeline.
