[0002] With the rapid advancement of industrialization and urbanization, pipeline transportation has been increasingly used in energy transmission, water conservancy allocation, environmental protection and other fields, and has become an indispensable infrastructure in modern society. However, the deposition and migration of sediment inside the pipeline is becoming increasingly serious, posing a significant threat to the safe and stable operation of the pipeline and its efficient transportation capacity. In this context, the introduction of the electrostatic principle has brought innovative solutions to the field of sediment monitoring. When solid particles such as sediment flow in the pipeline, static charges are generated due to physical effects such as collision and friction.

[0042] Before using the device, the staff controls the upper computer 601 according to the spacing between the two boreholes 101 to extend and retract the adapter rod 4, thereby driving the positioning ring 401 to move, thereby driving the adapter tube 402 to move, thereby changing the spacing between the two reversing tubes 7, thereby adapting to the boreholes 101 with different spacings. At this time, due to the effect of the sealing tube 405, the muddy water inside the sediment particle electrostatic sensor 3 can be prevented from leaking, thereby ensuring the accuracy of muddy water transportation. When the entire equipment is installed, the staff opens the sediment pipe 1, so that the water flows from the left end of the sediment pipe 1 to the right end of the sediment pipe 1, and further the water flows along the filter plate 9 into the water inlet pipe 2.

When the monitoring is completed, the muddy water continues to move to the right due to the action of the booster pump 301, and then reaches the inside of the sealed tube 405. At this time, the sampling top plate 506 is opened and the sampling plate 505 is closed, so that the muddy water reaches the inside of the outlet pipe 201 At this time, due to the action of the baffle spring 804, the baffle 8 is tightly attached to the moving tube 714 at the right end, thereby preventing large particles of impurities and muddy water from entering from the outlet pipe 201, thereby ensuring the accuracy of monitoring. Further, the upper computer 601 controls the baffle motor 803 to work, thereby driving the connecting block 801 to rotate, thereby driving the baffle 8 to rotate, so that the baffle 8 is opened, so that the muddy water inside the outlet pipe 201 returns to the inside of the sediment pipe 1, thereby realizing circulation.

[0044] When using the device, the staff closes the sediment pipe 1, and further drills two holes 101 at the bottom of the sediment pipe 1. The staff controls the upper computer 601 according to the spacing between the two holes 101 to make the adapter rod 4 extend and retract, thereby driving the positioning ring 401 to move, thereby driving the adapter pipe 402 to move, thereby changing the spacing between the two reversing pipes 7, thereby adapting to the holes 101 with different spacings. At this time, due to the effect of the sealing pipe 405, the muddy water inside the sediment particle electrostatic sensor 3 can be prevented from leaking, thereby ensuring the muddy water transport. The staff further inserts the mobile tube 714 into the borehole 101, and then rotates the reversing tube 7, so that the mobile tube 714 rotates, thereby driving the clamping strip 703 and the arc clamping strip 704 to rotate around the water inlet pipe 2 and the water outlet pipe 201, so that the clamping strip 703 and the axis of the sediment pipe 1 are in the same plane, and the arc clamping strip 704 is perpendicular to the axis of the sediment pipe 1. At this time, due to the rotation of the reversing tube 7, the entire device can be adapted to the two boreholes that are not on the same axis. 101, so that it can adapt to the curved sediment pipe 1, thereby increasing the use range of the equipment. At this time, the upper computer 601 controls the clamping strip motor 705 and the arc clamping strip motor 706 to work, so that the clamping strip 703 rotates to the horizontal, and at the same time makes the arc clamping strip 704 close to the inner wall of the sediment pipe 1. At this time, the upper computer 601 controls the moving rod 716 to contract, thereby driving the reversing tube 7 to move upward, so that the locking plate 701 is close to the bottom surface of the sediment pipe 1. At this time, due to the action of the locking plate 701 and the positioning plate 719 The locking tube 702 can be moved to the inside of the borehole 101. At this time, the upper computer 601 controls the air pump 709 and the air inlet valve 710 to work, so as to transport the gas inside the gas tank 708 to the inside of the locking tube 702, so that the locking tube 702 is deformed, so that the locking tube 702 is tightly attached to the borehole 101, and at the same time, the locking tube 702 is tightly attached to the moving tube 714, so as to prevent the mud and water inside the sediment pipe 1 from leaking from the borehole 101, thereby ensuring the monitoring accuracy and the stability of the water inlet pipe 2.

[0045] The working process of the present invention is as follows: when using the device, the staff closes the sediment pipe 1, and further the staff drills two boreholes 101 at the bottom of the sediment pipe 1. At this time, the staff controls the extension and retraction of the adapter rod 4 according to the spacing between the two boreholes 101, so that the two reversing pipes 7 are located at the bottom of the two boreholes 101. Further, the staff inserts the mobile pipe 714 into the borehole 101. At this time, the staff rotates the reversing pipe 7, so that the mobile pipe 714 rotates, thereby driving the clamping strip 703 and the arc-shaped clamping strip 704 to rotate around the water inlet pipe 2 and the water outlet pipe 201, so that the clamping strip 703 and the axis of the sediment pipe 1 are in the same plane, and at the same time, The arc-shaped clamping strip 704 is perpendicular to the axial plane of the sediment pipe 1. At this time, due to the rotation of the reversing tube 7, the entire device can be adapted to the two boreholes 101 that are not on the same axis, so that it can be adapted to the curved sediment pipe 1, thereby increasing the use range of the device. At this time, the upper computer 601 controls the clamping strip motor 705 and the arc-shaped clamping strip motor 706 to work, so that the clamping strip 703 rotates to the horizontal, and at the same time makes the arc-shaped clamping strip 704 close to the inner wall of the sediment pipe 1. At this time, the upper computer 601 controls the moving rod 716 to contract, thereby driving the reversing tube 7 to move upward, so that the locking plate 701 is in close contact with the bottom surface of the sediment pipe 1. At this time, due to the locking plate 701 and the The positioning plate 719 can move the locking tube 702 to the inside of the borehole 101. At this time, the upper computer 601 controls the air pump 709 and the air inlet valve 710 to work, so as to transport the gas in the gas tank 708 to the inside of the locking tube 702, so that the locking tube 702 is deformed, so that the locking tube 702 is in close contact with the borehole 101, and at the same time, the locking tube 702 is in close contact with the moving tube 714, so as to prevent the muddy water in the sediment pipe 1 from leaking from the borehole 101, thereby ensuring the monitoring accuracy and the stability of the water inlet pipe 2. When the entire equipment is installed, the staff opens the sediment pipe 1, so that water flows from the left end of the sediment pipe 1 to the The water flows along the right end of the sediment pipe 1, and further flows along the filter plate 9 into the water inlet pipe 2. At this time, due to the cleaning plate 901, large particles of impurities can be blocked outside the water inlet pipe 2, and at the same time, sediment and water can enter the water inlet pipe 2. At this time, due to the action of the flow meter 202, the muddy water flow inside the water inlet pipe 2 can be monitored. At this time, the host computer 601 controls the booster pump 301 to work, thereby increasing the internal pressure of the sediment particle electrostatic sensor 3, thereby ensuring the muddy water transportation effect, and further muddy water enters the induction tube 303. At this time, due to the electrostatic attraction, according to the different polarities of the charge source, the free electrons on the metal probe in the induction tube 303 will be close to or away from the surface of the induction tube 303.The positrons will move in the opposite direction, and the movement of the sediment particles will generate charge transfer, static electricity changes, and induced charges. The induction tube 303 senses the change in the amount of charge generated by the electron transfer, and the probe sensing surface senses the positive charge and outputs a signal. After the signal is conditioned inside the induction tube fixing ring 302, it is connected to the host computer 601. After the signal is transmitted to the host computer 601, it is monitored online, and the output amplitude change curve of the induced charge and the signal waveform diagram are output, so as to analyze the types of various sediment particles, thereby realizing real-time monitoring, thereby ensuring the accuracy of monitoring and improving the monitoring efficiency. When the monitoring is completed, the muddy water is discharged due to the booster pump 301. The action continues to move rightward, and then reaches the inside of the sealing tube 405. At this time, the sampling top plate 506 is opened, and the sampling plate 505 is closed, so that the muddy water reaches the inside of the outlet pipe 201. At this time, due to the action of the baffle spring 804, the baffle 8 is tightly attached to the moving tube 714 at the right end, thereby preventing large particles of impurities and muddy water from entering from the outlet pipe 201, thereby ensuring the accuracy of monitoring. Further, the upper computer 601 controls the baffle motor 803 to work, thereby driving the connecting block 801 to rotate, thereby driving the baffle 8 to rotate, so that the baffle 8 is opened, so that The muddy water inside the water outlet pipe 201 returns to the inside of the sediment pipe 1, thereby realizing circulation. At the same time, due to the rotation of the baffle 8, the rotation direction of the baffle 8 can prevent the muddy water inside the sediment pipe 1 from entering the inside of the water outlet pipe 201, thereby further ensuring the monitoring accuracy. When the staff needs to analyze the muddy water inside the sediment particle electrostatic sensor 3, the host computer 601 controls the sampling motor 503 to work, thereby driving the bottom bevel gear 501 to rotate, thereby driving the top bevel gear 502 to rotate, thereby driving the sampling plate 505 and the sampling top The plate 506 rotates, so that the sampling plate 505 is opened and the sampling top plate 506 is closed at the same time, so that the muddy water inside the sampling tube 5 only flows into the right end of the silt particle electrostatic sensor 3, thereby ensuring the accuracy of sampling and the sampling effect. Further, when the flow meter 202 detects that the flow inside the water inlet pipe 2 is small, the host computer 601 determines that the filter plate 9 is blocked. At this time, the host computer 601 controls the cleaning motor 902 to work, thereby driving the cleaning plate 901 to rotate, so as to clean the large particles of impurities on the filter plate 9, thereby ensuring the monitoring efficiency.
