The present invention discloses a high gravity field experiment cabin water level regulation device. The device comprises a model box, a water storage box, a volume block, a connection tube, a guidance device and a lifting device. The model box and the water storage box communicate with the connection tube, the volume block is vertically arranged in the water storage box, the volume block is slidingly connected with the water storage box through the guidance device, and the volume block moves up and down through driving of the lifting device. The high gravity field experiment cabin water levelregulation device regulates the height of the volume block up and down starting from the container relative volume change angle to circularly change the relative volume of the water storage box and achieve water level circular change so as to change the water level of the test box, solve the water level circular lifting problem in the high gravity field environment, solve the problem of fixed water amount circular usage in the high gravity field environment and solve the problem of damaging of the device caused by direct drainage in the high gravity field environment.
