[0043] In the specific implementation process of the embodiment, as Figure 4 , Figure 9As shown, the internal monitoring mechanism comprises a monitoring gear cavity (46) opened on the moving ring 40, a monitoring gear shaft 47 rotatably connected between the end walls of the monitoring gear cavity 46, a power output shaft of a monitoring motor 49 fixedly installed in the moving ring 40, a monitoring gear 48 fixedly installed on the outer surface of the monitoring gear shaft 47, the monitoring gear 48 engaged with a monitoring annular gear rack 35, the monitoring annular gear rack 35 rotatably installed on the moving ring 40, a deformation monitoring probe 39 fixedly connected to the end wall of the monitoring annular gear rack 35, an installation plate 36 fixedly installed on the end wall of the monitoring annular gear rack 35, a flow monitoring electric push rod 37 connected to the end wall of the monitoring annular gear rack 35, a flow monitoring sensor 38 fixedly connected to the end of the flow monitoring electric push rod 37, an installation block 32 fixedly connected to the end wall of the monitoring annular gear rack 35, a stress monitoring electric push rod 33 fixedly connected to the end wall of the installation block 32, a stress detector 34 fixedly connected to the end of the stress monitoring electric push rod 33, a fixed block 29 fixedly connected to the end wall of the monitoring annular gear rack 35, a water pressure detection electric push rod 30 fixedly connected to the end wall of the fixed block 29, a water pressure monitoring sensor 31 fixedly connected to the end of the water pressure detection electric push rod 30, the deformation monitoring probe 39, the flow monitoring sensor 38, the flow monitoring electric push rod 37, the stress monitoring electric push rod 33, the stress detector 34, the water pressure detection electric push rod 30, the water pressure monitoring sensor 31, the monitoring motor 49 and the data transmitter 9 are signal connected, and the data transmitter 9 is signal connected with a monitoring host computer.

[0044] When working, the moving mechanism drives the moving ring 40 to move in the pipeline 13 and the ball valve body 1, realizes monitoring of the ball valve body 1 and the pipeline 13, and can realize monitoring and collection of point data, starts the monitoring motor 49, thereby driving the monitoring gear shaft 47, thereby driving the monitoring gear 48 to rotate, the monitoring gear 48 is engaged with the monitoring ring gear 35, thereby making the monitoring ring gear 35 rotate by a corresponding angle, electrifies the stress monitoring electric push rod 33, thereby driving the stress detector 34 to move and tightly adhere to the inner wall of the pipeline 13 or the inner wall of the ball valve body 1, monitors the stress on the inner wall of the pipeline 13 or the ball valve body 1, and sends the monitored data to the data transmitter 9. The deformation monitoring probe 39 is close to the inner wall of the pipeline 13 or the inner wall of the ball valve body 1, monitors the deformation of the inner wall of the pipeline 13 or the ball valve body 1, and sends the monitored information to the data transmitter 9. The monitoring strain purpose is mainly to monitor the deformation of the steel pipe under the action of water pressure in the running process of the unit. The deformation of the steel pipe in the normal running process of the unit mainly changes with the change of water pressure and temperature, and the deformation of the steel pipe in the normal running process of the unit is elastic and recoverable. When the monitored strain increases in a trend (the water pressure does not increase), or the measured value suddenly changes, timely alarm or close the ball valve, electrify the water pressure detection electric push rod 30, drive the water pressure monitoring sensor 31 to move to a corresponding position, thereby monitoring the water pressure in the pipeline 13 or the ball valve body 1, and sending the monitored information to the data transmitter 9. When detecting that the pressure in the steel pipe is too high, an alarm is sent. The high water pressure is generally due to the fact that the water flow cutting time is too short, resulting in that the water pressure rising rate is too large. Through early warning, the running and maintenance personnel can be prompted to adjust the unit nozzle or ball valve closing time. In addition, during the shutdown or normal running process of the unit, the water pressure remains unchanged or changes slowly. When the water pressure in the steel pipe suddenly drops and the sudden drop value exceeds the set value, an alarm is sent or the ball valve is closed. The flow monitoring electric push rod 37 is electrified, thereby driving the flow monitoring sensor 38 to move, thereby monitoring the flow of water in the pipeline 13 or the ball valve body 1, and sending the monitored information to the data transmitter 9. The data transmitter 9 transmits the information to the monitoring host. In the normal running process of the unit, there is a certain relationship between the water flow and the unit load. When the load remains unchanged, the water flow will not change greatly. When the load changes slowly, the flow will not change sharply.When the flow of the unit is sharply changed (mutated) during shutdown or normal operation, and the flow is obviously larger than the flow required by the load of the unit, the main unit warning device alarms, and when the difference is greater than a certain value, the ball valve can be closed in time, the monitoring main unit sends a signal to the data transmitter 9, the data transmitter 9 transmits a signal to the stress monitoring electric push rod 33, the water pressure detection electric push rod 30, the flow monitoring electric push rod 37 and the monitoring motor 49, so that the stress monitoring electric push rod 33, the water pressure detection electric push rod 30, the flow monitoring electric push rod 37 and the monitoring motor 49 move, through the movement of the moving ring 40 and the rotation of the monitoring ring-shaped rack 35, thereby realizing monitoring and measuring multiple points, the obtained data is more effective, the moving ring 40 moves, thereby driving the cable 26 to move, thereby driving the line wheel 25 to rotate, thereby driving the line wheel shaft 28 to rotate, thereby driving the spring 27 to be tightened, and the spring 27 is tightened.
