[0002] Aqueduct refers to an overhead water channel that conveys channel water across rivers, valleys, depressions and roads. It is commonly used for irrigation and water delivery, as well as for flood and sand discharge. Large aqueducts can also be navigable. Aqueducts are mainly built with materials such as stone masonry, concrete and reinforced concrete. During the construction of the aqueduct, due to the characteristics of concrete, gaps will be left between the aqueducts, and the gaps between the aqueducts need to be installed with waterstops to stop water, thereby ensuring the water delivery function of the aqueduct. After the waterstop has been used for a certain period of time, due to various reasons, the waterstop will be damaged and need to be replaced. However, the replacement of the waterstop is now more troublesome. It is necessary to shut down the water supply of the aqueduct, cut off the power, jump into the aqueduct, and manually replace the waterstop.

[0015] Method of use of the present invention: In the initial state: A pair of the protective cover bases 13 and the waterstop limit plates 26 in the protective cover 14 are provided with spare waterstops 35, the water blocking plates 22 and the connecting plates 20 are parallel to the ground, the No. 2 electric push rod 21 is in a fully retracted state, the water blocking airbag 24 is in an uninflated state, the telescopic membrane 23 is in a retracted state, the friction wheel 39 is in contact with the spare waterstop 35, the No. 1 electric push rod 27 is in a fully retracted state, the torsion spring 28 is in an extended state, the suction pipe of the No. 1 water pump 41 is connected to the water flow in the aqueduct 11, and the rotating plate 51 is parallel to the fixed plate 48.

[0016] When the personnel who normally inspect the aqueduct find that a section of the water stop of the aqueduct is abnormal, the present invention can be started through the corresponding control terminal 12. After the control terminal 12 is started, the control terminal 12 will drive the No. 1 motor 30 to start. After the No. 1 motor 30 is started, its motor shaft will drive the No. 1 sprocket 31 to rotate. The rotation of the No. 1 sprocket 31 will drive the No. 2 sprocket 32 ​​to rotate through the chain 34, thereby driving the connecting rotating plate 33 to rotate, thereby driving the connecting plate 20 to rotate, so that the water blocking plate 22 completes a 90° flip. When the water blocking plate 22 completes the flip, the No. 2 air pump 43 will be started under the action of the control terminal 12, so as to supply air to the water blocking air pump 43 through the air supply pipe 44. The air is delivered into the water-blocking airbag 24, thereby expanding the water-blocking airbag 24. As the water-blocking airbag 24 expands, the water-blocking airbag 24 will contact the inner wall of the aqueduct 11 and the pressure plate 36, thereby blocking a part and preventing the water flow from continuing to enter between the water-blocking plates 22. The control terminal 12 will start the No. 2 electric push rod 21. After the No. 2 electric push rod 21 is started, it will begin to stretch, so that the water-blocking plates 22 move to both sides, and the telescopic membrane 23 is stretched. At this time, the distance between the water-blocking plates 22 is greater than the distance between the pressure plates 36. Then, the No. 2 water pump 18 is started under the action of the control terminal 12. After the No. 2 water pump 18 is started, it will pump water to the water pumping pipe through the connecting hose 19. 25 is pumped out, thereby pumping out the space blocked in the water blocking plate 22, thereby pumping out the excess water between the water blocking plates 22 and discharging it into the aqueduct 11. When the space between the water blocking plates 22 is pumped out, the No. 1 water pump 41 is started under the action of the control terminal 12. After the No. 1 water pump 41 is started, the water in the pressure plate 36 is pumped back through the water pipe 42, so that the pressure membrane 37 stops continuously applying pressure to the water stop belt 35. Then the No. 1 electric push rod 27 is started under the action of the control terminal 12. After the No. 1 electric push rod 27 is started, it will drive the lifting plate 40 to rise, and the lifting plate 40 will drive the pressure plate 36 to rise, so that the pressure plate 36 The waterstop 35 is no longer pressurized, and the torsion spring 28 is stretched and deformed. Then, the control terminal 12 will start the No. 1 air pump 46. After the No. 1 air pump 46 is started, air will be evacuated from the air suction cylinder 47, so that the air suction cylinder 47 will evacuate air into the waterstop 35, thereby adsorbing the waterstop 35. Then, the electric slider 45 is started and begins to slide on the slide rail 15. Due to the limitation of the waterstop 35 by the pressure plate 36, the waterstop 35 begins to slide, so that the waterstop 35 enters the waterstop limiting plate 26. At the same time, the control terminal 12 will also start the No. 2 motor 38. After the No. 2 motor 38 is started, its motor shaft will drive the friction wheel 39 to rotate.Thus, under the friction force of the friction wheel 39 and the traction of the electric slider 45, the water stop belt 35 is continuously drawn out from the aqueduct 11 and enters the empty water stop belt limit plate 26 to wait for subsequent processing. When the water stop belt 35 is completely drawn out and enters the water stop belt limit plate 26, the protective cover base 13 and the protective cover 14, the No. 2 motor 38 will stop automatically, and the No. 3 motor 53 will be started under the action of the control terminal 12. After the No. 3 motor 53 is started, its motor shaft will drive the connecting shaft 50 to rotate, thereby driving the rotating plate 51 to rotate, so that the drying component 52 extends into the interior of the aqueduct 11, and then the drying component 52 is at the control terminal 12 The electric slider 45 slides back and forth under the action of the control terminal 12. After a certain period of time, the drying component 52 completes the drying of the space isolated by the water blocking plate 22. The third motor 53 is driven again under the action of the control terminal 12 to complete the resetting of the drying component 52 and the rotating plate 51. The second motor 38 on the water stop limit plate 26 with the spare water stop 35 on the other side is started under the action of the control terminal 12, so that the water stop 35 is pushed into the gap between the aqueducts 11 through the friction wheel 39. At the same time, the electric slider 45 is moved back and forth under the action of the control terminal 12. The first water pump 46 is driven to start by the control terminal 12, so that the suction cylinder 47 absorbs the entrance end of the spare water stop 35, thereby completing the installation of the spare water stop 35 through the sliding of the electric slider 45. When the water stop 35 completely enters the aqueduct 11, the first electric push rod 27 will begin to shrink under the action of the control terminal 12, so that the pressure plate 36 and the new pressure plate 36 are tightly fitted under the action of the first electric push rod 27 and the torsion spring 28. At the same time, the first water pump 41 is also started under the action of the control terminal 12, so that the water in the aqueduct 11 is diverted through the water transfer The tube 42 is poured into the pressure plate 36, so that the pressure membrane 37 maintains a certain pressure on the water stop belt 35, so that the water stop belt 35 is closed to prevent water leakage, and then the No. 1 air pump 46 stops driving, and the No. 2 electric push rod 21 is reset under the action of the control terminal 12, and the No. 2 air pump 43 starts to pump air into the water blocking airbag 24 under the action of the control terminal 12, so that the water blocking airbag 24 is no longer inflated, and then under the action of the control terminal 12, the No. 1 motor 30 starts to drive the No. 1 sprocket 31 to rotate, thereby driving the No. 2 sprocket 32 ​​to rotate through the chain 34, thereby driving the water blocking plate 22 to rotate, so that the water blocking plate 22 is reset, which is convenient for next use.Thus, the water stop 35 can be automatically replaced without shutting down the water supply of the aqueduct or affecting the water supply of the aqueduct. After use, the user needs to manually remove the protective cover 14, take away the replaced water stop 35, and place the newly prepared spare water stop 35 in the corresponding water stop limit plate 26.
