The invention relates to a pool wave test device. One end is connected with a pool fixing structure via angular contact ball bearings and a deep groove ball bearing to realize horizontal and verticalmovement of a frame. a screw rod and a handwheel are arranged at one end of the frame and combined with the deep groove ball bearing to adjust a vertical position; in the horizontal direction, the frame can rotate around the angular contact ball bearings to adjust a horizontal position, and the two directions are provided with locking structures respectively to lock the main frame in the horizontal and vertical positions; and the other end of the frame is provided with a pool wave tester to carry out wave test in a specific position. Before test, the horizontal angle and the vertical height ofthe frame are adjusted, the frame is locked in the needed position, and the other end of the frame is fixedly provided with wave tester. During test, when the test position needs to be tested, the locking device is released, the horizontal and vertical positions are adjusted again, and the locking device is then locked again. The device is lifted after test and fixed at one side, and interferencein subsequent test is avoided.
