Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a pipeline repair device for water conservancy projects. Background Technology

[0002] During use, underground pipelines may leak or break due to their own internal or external factors. In such cases, emergency repairs are required. The repair process must be carried out while the medium inside the pipeline is being transported normally, and the soil layer at the damaged area must be completely removed so that workers can repair the damaged section of the pipeline.

[0003] Chinese Utility Model Patent Publication No. CN212389946U discloses a pipe repair device for water conservancy projects, comprising a cover with arc-shaped sides at the bottom end. A sealing gasket is fixedly installed on the bottom end of the cover, and fixing plates are symmetrically fixed at both ends of the cover. This device can be connected to the suction pipe of an external water pump via a connecting pipe. When workers place the cover into the pit at the point of pipe repair, the water accumulated in the pit is sucked in by the bottom end of the U-shaped pipe and then discharged out of the pit by the external water pump through the N-shaped pipe and the connecting pipe. This effectively drains the water from the pit, preventing further water accumulation when workers enter to repair the pipe, thus facilitating the repair work. Furthermore, the cover and the first arc-shaped plate both contribute to repairing the damaged area of ​​the pipe, providing two layers of protection and improving the device's reliability.

[0004] There are still some problems in the current pipeline repair process. When repairing pipelines, clamps are needed to horizontally fix the two sides of the pipeline to prevent the pipeline from breaking during repair. However, most existing clamps use threaded rods for adjustment. Due to the complex environment of pipeline repair, dirt and other impurities can easily adhere to the threads, thus affecting the normal rotation of the threaded rod. Therefore, this application provides a pipeline repair device for water conservancy projects to meet the needs. Utility Model Content

The handle 212 is fixedly connected to the top of the insertion rod 209, and the bottom of the insertion rod 209 is fixedly connected to the pressure block 210. The upward movement of the handle 212 causes the insertion rod 209 to drive the pressure block 210 to move, thereby facilitating the disengagement of the locking teeth 211 on the pressure block 210 from the gear 207. Then, the bracket 204 is moved. The pulley 202 on the mounting base 203 slides on the sliding rod 201, increasing the overall stability of the bracket 204. The movement of the bracket 204 adjusts the position of the frame 102.

[0030] The pipe is placed inside the arc groove 104, and then the clamp 106 is rotated to make the rubber pad 107 fit against the pipe. First, the limiting rod 310 is pulled away from the inside of the retaining ring 313. Then, the position of the crossbar 302 is moved by the handle 308, so that the retaining rod 305 on the linkage plate 304 is locked inside the retaining groove 307. Then, the crossbar 302 is moved downward, so that the rubber pad 107 on the clamp 106 is tightly fitted against the inner wall of the pipe, and the position of the crossbar 302 is fixed. The elastic force of the second spring 312 makes the limiting rod 310 inserted into the inside of the retaining ring 313, thereby facilitating the fixation of the position of the crossbar 302.
