[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a water supply engineering pipeline repair equipment includes a tube 1. Two mounting rings 2 are arranged on the outer surface of the tube 1. The inner wall of one mounting ring 2 is connected to the outer surface of the tube 1, and the inner wall of the other mounting ring 2 is slidably connected to the outer surface of the tube 1. The tube 1 supports the components to be carried, and one of the mounting rings 2 provides support for the rubber sleeve 4. When the other mounting ring 2 moves, the gallows 6 and the arc-shaped push plate 7 are pushed to support from the inside of the rubber sleeve 4, so that the rubber sleeve 4 is propped up and contacts the inner wall of the tube 1, thereby preventing water from flowing out of the outside of the tube 1.

[0024] The inner sides of the two mounting rings 2 are each provided with a mounting groove 3, and the inner wall of the mounting groove 3 is connected with a rubber sleeve 4. The mounting groove 3 increases the stability of the banana. The rubber sleeve 4 is made of rubber material, and the rubber material has good ductility and elasticity, and can well fill and seal the gap. An electric push rod 5 is arranged on the outside of the tube 1, and the output end of the electric push rod 5 is connected to one side of the other mounting ring 2. The electric push rod 5 provides power for moving the mounting ring 2. There are two electric push rods 5, and the two electric push rods 5 have good balance. The outer surface of the tube 1 is connected with a base 8, and the fixed end of the electric push rod 5 is installed on one side of the base 8. When the electric push rod 5 pushes the mounting ring 2 to move its position, the mounting ring 2 will simultaneously generate a reaction force, and the base 8 provides a supporting force for the electric push rod 5, so that the electric push rod 5 has the supporting force to push the mounting ring 2 to move its position.

[0025] A plurality of gallows 6 are connected to one side of the two mounting rings 2 located inside the rubber sleeve 4, and an arc-shaped push plate 7 is connected to the top of each of the plurality of gallows 6. The outer surface of the arc-shaped push plate 7 contacts the inner wall of the rubber sleeve 4. There are four gallows 6 in number, and the four gallows 6 are arranged in a circular equidistant array. The gallows 6 is composed of two swing arms, and the two ends of the two swing arms are rotatably connected to the two mounting rings 2. The other ends of the two swing arms are connected by a pin shaft. The mounting ring 2 is moved to push the gallows 6 to change its angle. The gallows 6 changes its angle and changes its support height for the arc-shaped push plate 7.

[0026] A valve 12 is detachably mounted on the other end of the tube 1 . After the rubber sleeve 4 is propped up inside the pipe, the valve 12 is closed to prevent water from flowing out of the tube 1 .

[0027] A groove 15 is provided at one end of the arc-shaped push plate 7, and a protrusion 16 is connected to the other end of the arc-shaped push plate 7. The inner wall of the groove 15 is slidably connected to the outer surface of the protrusion 16. The groove 15 has a space for accommodating the protrusion 16. The groove 15 and the protrusion 16 increase the length of the arc-shaped push plate 7 and the contact area between the arc-shaped push plate 7 and the rubber sleeve 4.

[0028] Two support rings 9 are connected to the outer surface of the tube 1, and the two support rings 9 are symmetrical. The inner walls of the two support rings 9 are rotatably connected with rollers 10. The support rings 9 provide stable support for the rollers 10, so that the rollers 10 have stability. The rotation of the rollers 10 facilitates pushing the tube 1 and other components to move to the inside of the damaged pipe.

[0029] One end of the tube 1 is connected to a focusing cover 11 , which has a trumpet-shaped appearance. The focusing cover 11 guides the direction of water flow to make the water flow toward the center of the tube 1 , thereby reducing the pressure outside the rubber sleeve 4 .

[0030] A slide groove 13 is provided on the inner side of the tube 1, and a guide rail 14 is connected to the inner wall of another mounting ring 2. The outer surface of the guide rail 14 is slidably connected to the inner wall of the slide groove 13. The slide groove 13 guides the sliding direction of the guide rail 14 to maintain the stability of the guide rail 14. The guide rail 14 limits the rotation of the mounting ring 2 so that the mounting ring 2 has only a straight sliding trajectory.

[0031] It should be noted that in actual use of the device, the water supply engineering pipeline repair equipment is first inserted into the damaged pipeline. Before the water supply engineering pipeline repair equipment is inserted into the damaged pipeline, the valve 12 is first opened to make the valve 12 in an open and closed state. After the water supply engineering pipeline repair equipment is inserted into the damaged pipeline, water can flow out from the inside of the tube 1, reducing the impact on the water supply engineering pipeline repair equipment. Subsequently, the electric push rod 5 is started to push the installation ring 2 to move its position. While the installation ring 2 moves its position, the gallows 6 is pushed to change its angle. After the gallows 6 changes its angle, it pushes the arc-shaped push plate 7 to move its position. After the arc-shaped push plate 7 moves its position, it supports the rubber sleeve 4 and pushes the rubber sleeve 4 to tightly contact the inner wall of the damaged pipeline to prevent water from flowing out from the outside of the rubber sleeve 4. After the rubber sleeve 4 contacts the damaged pipeline, the valve 12 is closed to prevent water from flowing out from the inside of the tube 1, thereby forming a blockage for the damaged pipeline.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
