[0028] When the underwater torque sensor needs to be calibrated, the device is put underwater, and the sealing mechanism 5 is taken out from the inside of the partition 3 by artificial, and then the sealing mechanism 5 is connected with the torque sensor, if the torque sensor is calibrated on water, the sealing mechanism 5 is directly connected with the torque sensor, thereby, whether on water or underwater operation, the torque sensor can be calibrated, and the versatility of the sensor is improved.

[0029] In order to provide power for the calibration of the torque sensor, as shown in Figure 2 and Figure 3 The power mechanism 2 includes an oil tank 201, a sealing ring 202, a liquid outlet pipe 203, a hydraulic pump 204, a shaft coupling 205 and a motor 206, and the oil tank 201 is connected to the inner wall of the box 1 by screwing, the liquid outlet pipe 203 is connected to one side of the oil tank 201, the sealing ring 202 is sleeved on the connection between the liquid outlet pipe 203 and the oil tank 201, the hydraulic pump 204 is fixedly connected to the top of the partition plate 3, the shaft coupling 205 is sleeved on the outer wall of the driving shaft end of the hydraulic pump 204, and the motor 206 is inserted into the inner wall of the shaft coupling 205, and the liquid outlet pipe 203 is communicated with the oil outlet of the hydraulic pump 204, and the model of the hydraulic pump 204 is A10VSO.

[0030] After the motor 206 is started, power is transmitted to the driving shaft of the hydraulic pump 204 through the shaft coupling 205, so that the hydraulic pump 204 starts to work, and the hydraulic oil is extracted from the oil tank 201 through the liquid outlet pipe 203. Because the liquid outlet pipe 203 is communicated with the oil outlet of the hydraulic pump 204, the extracted hydraulic oil will be pressurized in the hydraulic pump 204, thereby providing power for the subsequent sealing mechanism 5 work.

After receiving the torque, the torque sensor converts it into an electrical signal and transmits it to the PLC, then the PLC adjusts the flow of the hydraulic pump 204 by changing the rotating speed of the motor 206, thereby changing the size of the torque output by the hydraulic torque loading cylinder 503, so that the torque received by the torque sensor is closer to the target value. If the calibration is carried out on the ground, the flange plate 506 can be directly connected to the torque sensor.
