Clinical radiation measurement cannot be performed directly in the human body, and a substitute similar to human tissue needs to be found. The most widely used clinical radiation measurement around the world is to use a test water tank to simulate the internal structure of the human body for detection. With the continuous development of science and technology, the control structure is constantly improving, and the transmission accuracy of the mechanical structure is constantly improving.

The inclination sensor is fixedly connected to the fixed plate by screws to sense the horizontality of the fixed plate, thereby realizing the horizontality detection of the detection water tank. When the detection water tank is deflected, the inclination sensor senses the inclination of the fixed plate. The inclination sensor calculates the required rising or falling distance in the x and y axis directions by measuring the offset angle of the fixed plate, and converts it into a pulse signal and sends it to the PLC. After receiving the instruction, the PLC sends a pulse signal to the two leveling motors. The two leveling motors receive the pulse signal and transmit it to the motor. The two leveling motors rise and fall synchronously, thereby achieving the purpose of adjusting the water level. This type of leveling method is to flip and adjust along the axial direction of the two supporting parts; the adjustment plate 4 in this technical solution is the same as the fixed plate of a medical detection three-dimensional water tank disclosed in the publication number CN208984807U in usage, so it can be regarded as prior art;
