[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A pipeline pressurized leak sealing device includes two chain fixing belts, four tie rod bolts, two fixing frames, a connecting rod, a square-headed screw, and several leak-sealing components. The two fixing frames are arranged in parallel. The two ends of the connecting rod are fixedly connected to the middle of the top surface of the two fixing frames. The fixing frames have symmetrical elongated holes on both sides. The upper ends of the four tie rod bolts are respectively set in the four elongated holes by bolts, and the lower ends are respectively threaded to the two ends of the two chain fixing belts. The square-headed screw is vertically set in the middle of the connecting rod by threaded connection. The upper end of the connecting rod has a turning square head. The leak-sealing components are placed at the lower end of the connecting rod.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, a pipeline pressurized leak sealing device includes two chain fixing belts 2, four tie rod bolts 3, two fixing frames 4, a connecting rod 5, a square-headed screw 8, and several leak sealing components 10. The two fixing frames 4 are arranged in parallel. The two ends of the connecting rod 5 are fixedly connected to the middle of the top surface of the two fixing frames 4. An arc-shaped pad 7 is provided in the middle of the bottom surface of the two fixing frames 4, and elongated holes 6 are symmetrically opened on both sides. The upper ends of the four tie rod bolts 3 are respectively set in the four elongated holes 6 by bolts, and the lower ends are respectively threaded to the two ends of the two chain fixing belts 2. The square-headed screw 8 is vertically set in the middle of the connecting rod 5 by threaded connection. The upper end of the connecting rod 5 is provided with a turning square head 9. The leak sealing component 10 is an arc-shaped piece cut and ground from scrap steel pipes of different diameters and placed at the lower end of the connecting rod 5. A sealing gasket is provided on the bottom surface of the leak sealing component 10.

[0018] The working process of this utility model:

[0019] When pipe 1 is damaged and leaks, place two fixing brackets 4 on both sides of the leak point. The arc-shaped pad 7 should be tightly attached to pipe 1. Two chain fixing straps 2 should be wrapped around the pipe and tightly fixed in the elongated hole 6 with four tie rod bolts 3 to connect with the two fixing brackets 4. Ensure that the fixing brackets 4 and the chain fixing straps 2 can hold the pipe 1 tightly. Then, select a plugging part 10 made of steel pipe with a diameter one size larger than the pipe to be repaired and place it at the leak point. The sealing gasket should be tightly attached to pipe 1. Use a wrench to turn the square head 9 so that the square head screw 8 descends and tightly presses against the plugging part 10, pressing it onto the leak point. At this time, weld the plugging part 10 and pipe 1. After welding, loosen and turn the square head 9 so that the square head screw 8 rises and the chain fixing straps 2 and fixing brackets 4 are released. The welding of the current leak point is completed. Repeat the above steps to continue the repair work of the next leak point.

[0020] When the pipe diameter is different, the repair of leak points of different pipe diameters can be adapted by increasing or decreasing the number of chain links of the chain-type fixing belt 2 or adjusting the tightening length of the tie rod bolt 3 and selecting the sealing parts 10 with different curvatures.
