[0019] like Figure 1-Figure 9 As shown, the present invention discloses a device for monitoring a pressure steel pipe, comprising: A ball valve body 1, wherein both sides of the ball valve body 1 are connected to a connection box 10 through a connection assembly, and one end of the connection box 10 away from the ball valve body 1 is connected to a pipeline 13 through a connection assembly, and a moving ring 40 is provided on the inner wall of the pipeline 13, and a motion mechanism is provided between the moving ring 40 and the inner wall of the pipeline 13 to drive the moving ring 40 to move between the pipeline 10, the connection box 10 and the ball valve body 1; An internal monitoring mechanism, which is disposed on the moving ring 40 and is used to monitor the deformation of the inner wall of the pipe 13; An external monitoring mechanism, which is disposed on the outer wall of the pipeline 13 and is used to monitor the stress deformation of the outer wall of the pipeline 13; A sealing monitoring mechanism, which is detachably arranged on the pipeline 13 and is used to monitor the sealing performance of the connection assembly; The connection box 10 is provided with a wire-receiving mechanism, one end of the cable is wound around the wire-receiving mechanism, and the other end is connected to the moving ring 40 to supply power to the internal monitoring mechanism and to provide a pulling and recovering force.

[0020] In the specific implementation process of this embodiment, Figure 4 , Fig. 9As shown, the internal monitoring mechanism includes a monitoring gear cavity (46) opened on the moving ring 40, a monitoring gear shaft 47 is rotatably connected between the end walls of the monitoring gear cavity 46, the monitoring gear shaft 47 is connected to the power output shaft of a monitoring motor 49 fixedly installed in the moving ring 40, a monitoring gear 48 is fixedly installed on the outer surface of the monitoring gear shaft 47, the monitoring gear 48 is meshed with a monitoring annular rack 35, the monitoring annular rack 35 is rotatably installed on the moving ring 40, a deformation monitoring probe 39 is fixedly connected to the end wall of the monitoring annular rack 35, a mounting plate 36 is fixedly installed on the end wall of the monitoring annular rack 35, a flow monitoring electric push rod 37 is connected to the end wall of the monitoring annular rack 35, a flow monitoring sensor 38 is fixedly connected to the end of the flow monitoring electric push rod 37, and the monitoring A mounting block 32 is fixedly connected to the end wall of the measuring annular rack 35, a stress monitoring electric push rod 33 is fixedly connected to the end wall of the mounting block 32, a stress detector 34 is fixedly connected to the end of the stress monitoring electric push rod 33, a fixing block 29 is fixedly connected to the end wall of the monitoring annular rack 35, a water pressure detection electric push rod 30 is fixedly connected to the end wall of the fixing block 29, a water pressure monitoring sensor 31 is 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, and the monitoring motor 49 are connected to the data transmitter 9 for signal connection, and the data transmitter 9 is connected to the monitoring host for signal connection; During operation, the motion mechanism drives the moving ring 40 to move in the pipeline 13 and the ball valve body 1, so as to monitor the ball valve body 1 and the pipeline 13, and monitor and collect point data, start the monitoring motor 49, thereby driving the monitoring gear shaft 47, thereby driving the monitoring gear 48 to rotate, and the monitoring gear 48 is engaged with the monitoring annular rack 35, so that the monitoring annular rack 35 rotates a corresponding angle, and energizes the stress monitoring electric push rod 33, thereby driving the stress detector 34 to move and fit closely to the inner wall of the pipeline 13 or the inner wall of the ball valve body 1, The stress on the inner wall of the pipeline 13 or the ball valve body 1 is monitored, and the monitored data is sent 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, and the deformation of the inner wall of the ball valve body 1 caused by the pipeline 13 is monitored, and the monitored information is sent to the data transmitter 9. The purpose of monitoring the strain is mainly to monitor the deformation of the steel pipe under the action of water pressure during the operation of the unit. The deformation of the steel pipe during the normal operation of the unit mainly changes with the changes in water pressure and temperature, and the deformation of the steel pipe during the normal operation of the unit is elastic and recoverable. The pressure increases and the strain increases. Reduce the strain and make it smaller. When the monitored strain tends to increase (the water pressure does not increase) or the measured value suddenly changes, timely alarm or close the ball valve, energize the water pressure detection electric push rod 30, drive the water pressure monitoring sensor 31 to move to the corresponding position, so as to monitor the water pressure in the pipeline 13 or the ball valve body 1, and send the monitored information to the data transmitter 9. When the pressure in the steel pipe is detected to be too high, an alarm is issued. The high water pressure is generally caused by the short time of cutting off the water flow, resulting in excessive water pressure rise rate. The early warning can prompt the operation and maintenance personnel to adjust the unit needle or ball valve closing time. In addition, the unit is shut down or During normal operation, the water pressure remains unchanged or changes slowly. When the water pressure in the steel pipe drops suddenly and the sudden drop value exceeds the set value, an alarm is given in time or the ball valve is closed, and the flow monitoring electric push rod 37 is energized to drive 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, which transmits the information to the monitoring host. During normal operation of the unit, there is a certain relationship between the water diversion flow rate and the unit load. When the load remains unchanged, the water diversion flow rate will not change significantly, and when the load changes slowly, the flow rate will not change dramatically.When the flow rate of the unit increases sharply (mutated) during shutdown or normal operation, and is significantly greater than the flow rate required by the unit load, the host early warning device will give an alarm. When the difference is greater than a certain value, an alarm can be given in time or the ball valve can be closed. The monitoring host sends a signal to the data transmitter 9, and 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 annular rack 35, monitoring and measurement of multiple points are achieved, and the data obtained by monitoring is more effective. The moving ring 40 moves, thereby driving the cable 26 to move, thereby driving the wire wheel 25 to rotate, thereby driving the wire wheel shaft 28 to rotate, thereby driving the spring 27 to tighten, and after the spring 27 is tightened, it is convenient for the wire wheel 25 to reset.
