[0048] Embodiment three: different from the above embodiment and the present embodiment is:

[0050] As Figure 6 、 Figure 7 and Figure 8 shown in the specific embodiments, the connecting shell 402 side wall interactive through the plug-in setting of the top rod 4021, the top rod 4021 end fixedly provided with the pressing plate 4022 outside the connecting shell 402, the pressing plate 4022 diameter is greater than the diameter of the top rod 4021, the top rod 4021 end fixedly provided with the drive rack 404 inside the connecting shell 402, the drive rack 404 inside the activity through the setting of the horizontal plug rod 4042, the horizontal plug rod 4042 one side end fixedly provided in the connecting shell 402 inside, the horizontal plug rod 4042 outer surface activity sleeve set with reset spring 4043, reset spring 4043 both sides end and the drive rack 404 end and the connecting shell 402 inner wall are respectively interlocked. In the process of moving the drive rack 404 along the horizontal plug rod 4042 moves, and the reset spring 4043 is compressed, and the reset spring 4043 is convenient for resetting later, and the drive rack 404 moves to drive the bottom meshing positioning gear 4041 to start rotating, as Figure 6 and Figure 8 shown, the positioning gear 4041 rotates clockwise at this time, driving the surface of the guide disc 405 to rotate clockwise synchronously, and in the process of rotating the guide disc 405, the position of the spiral track 4051 changes, driving the adapter block 4052 and the connecting rod 4053 to move downward synchronously.

[0051] The implementation principle of the water pipeline leak repairing device of the embodiment is as follows:

[0052] First, the operator needs to detect the damaged position, and then the support frame 100 is installed on the surface of the water pipeline body 500 as a whole, wherein the entire water pipeline body 500 is clamped by the fastening ring 101 and the support ring 102, the gap 1012 on the surface of the fastening ring 101 is correspondingly matched with the crack on the surface of the water pipeline body 500, and the arc-shaped cross beam 103 is rotated and installed transversely on the surfaces of the two support side plates.

[0053] Then the user needs to start the electric push rod 201, and the bottom drive motor 203 is driven to move downward synchronously by the output end of the electric push rod 201, and the drive motor 203 end is connected and provided with the grinding disc 2031, when the grinding disc 2031 and the crack surface are in contact, the drive motor 203 is started, and the grinding disc 2031 is rotated by the drive motor 203, and the grinding disc 2031 can rotate the surface of the water pipeline body 500 as a whole at this time.

[0054] At the same time, the operator needs to manually pull back and forth the handle 2011, and the connecting block 202 on the surface of the handle 2011 starts to move along the limiting sliding groove 2022, and the limiting sliding groove 2022 is inclined, so that the position of the polishing disc 2031 at the end is synchronously moved, but the moving angle is small, so that the metal plate can be in full contact with the water pipeline body 500.

[0055] When the polishing is completed, the driving motor 203 is turned off, the electric push rod 201 is started to reset the position of the driving motor 203, and the metal plate to be welded is covered on the surface of the water pipeline body 500. Then, the arc-shaped cross beam 103 is disassembled, the arc-shaped cross beam 103 is flipped over as a whole, until the bottom of the arc-shaped cross beam 103 is in contact with the positioning plate 104, and the position of the arc-shaped cross beam 103 is positioned.

[0056] In the process of rotating the arc-shaped cross beam 103, the central shaft of the arc-shaped cross beam 103 is connected with the rotating shaft 3011, at this time the rotating shaft 3011 drives the rotating disc 301 to start rotating, and the rotating disc 301 drives the position of the positioning protrusion 3012 on the surface to move, thereby pulling the connecting piece 302 sleeved with the positioning protrusion 3012 to start moving left and right, and the connecting piece 302 moves along the limiting insertion rod 3022 to move upward, thereby limiting the movement of the connecting piece 302, and the movement of the connecting piece 302 drives the position of the swing arm 303 to change, and the movement of the swing arm 303 drives the end of the extrusion unit 400 to start moving.

[0057] Since the swing arm 303 is inclined, the swing arm 303 drives the two extrusion units 400 to start moving towards the center, and the vertical rod 4012 at the bottom of the extrusion unit 400 moves horizontally along the horizontal plate 4013. In the moving process, the connecting shell 402 is driven to move above the gap of the water pipeline body 500, at this time the pressing plates 4022 on the surfaces of the two extrusion units 400 are close to each other and are extruded, thereby driving the top rods 4021 to move into the connecting shell 402, respectively.

[0058] In the moving process, the driving rack 404 moves along the horizontal insertion rod 4042, and the reset spring 4043 is compressed. The reset spring 4043 facilitates resetting in the later stage, and the movement of the driving rack 404 drives the bottom engaged positioning gear 4041 to start rotating, like Figure 6 and Figure 8As shown, at this time the positioning gear 4041 rotates clockwise, driving the guide disc 405 on the surface to rotate clockwise synchronously, and in the process of rotating the guide disc 405, the position of the spiral track 4051 changes, driving the adaptive block 4052 and the connecting rod 4053 to move downward synchronously, and the connecting rod 4053 moves downward to push the push rod 4031 and the flat plate 4032 at the bottom to move, and the flat plate 4032 is extruded with the metal plate to be welded on the surface of the water pipeline body 500, reducing the danger brought by hand extrusion.
