Shallow water flow sound wave testing device

The invention discloses a shallow water flow sound wave testing device. The device comprises: a reaction kettle, which is provided with a test cabin and enables a side surface extending along a lengthdirection of the reaction kettle to apply a confining pressure to the test cabin; a sound wave test assembly, which is arranged in the test cabin and comprises a transmitting piece and a receiving piece, wherein a connecting line of the transmitting piece and the receiving piece is perpendicular to the length direction; a thrust assembly, which is disposed at one end, extending in the length direction, of the reaction kettle, with at least part of the thrust assembly extending into the test cabin; a liquid injection assembly, which is communicated with the test cabin; and a control part, which is electrically connected to the transmitting piece, the receiving piece, a temperature and pressure test assembly, the thrust assembly and a liquid injection assembly, and is used for acquiring thesound wave information tr
