Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline maintenance, and specifically relates to a temporary leak repair device for pipelines. Background Technology

[0002] The underground powerhouse of a hydroelectric power station typically houses equipment pipelines such as fire-fighting pipelines and water supply pipelines. Some of these pipelines are installed on the walls, while others are suspended from the ceiling. As the service life of these pipelines increases, some may experience seepage or leakage.

[0003] When pipes installed at a relatively high height, 2-3 meters above the ground, leaks occur, and inspection personnel are unable to handle them promptly due to operational difficulties. Usually, a bucket is used to catch the leaking water from below to stop the adverse effects of the leak. For pipes installed at a relatively low height, a waterproof cover or cement is usually used for temporary water blocking. Pipe repairs are then carried out by professional maintenance personnel when they arrive later.

[0004] Therefore, for leaking pipes located 2-3 meters away, inspection personnel are usually unable to repair the leaks in a timely manner due to the inconvenience of operation, which in turn leads to water pipe leaks and water accumulation in the factory. Utility Model Content

[0005] This utility model provides a temporary leak repair device for pipes to solve the problem of leaks in high-altitude pipes that are difficult to repair in a timely manner.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A temporary leak repair device for pipes includes a handheld part, a receiving cavity for loading repair fluid is provided in the handheld part, a repair tube is formed at the end of the handheld part, and a push rod is formed at the tail of the handheld part. The repair tube is connected to the receiving cavity, and the repair fluid can be pushed out from the end of the repair tube by pushing the push rod. The end of the handheld part is provided with a guide airbag for transporting the repair fluid. The guide airbag is housed close to the repair tube and can be inflated and deployed.

[0007] Furthermore, the handheld part is also provided with an inflation channel communicating with the air guide bag, and an inflation pump is provided in the inflation channel, the inflation pump extending out of the handheld part; Pushing the inflation pump inflates and unfolds the airflow guide bag, while pulling back the inflation pump retracts the airflow guide bag.

[0008] Furthermore, a liquid guide tube is fixed to the side of the air bladder facing the leak repair tube. The liquid guide tube can be detachably connected to the receiving cavity, and the liquid guide tube can be folded along with the air bladder.

[0009] Furthermore, after the liquid guide tube is deployed with the air guide bladder, the end of the liquid guide tube extends out of the end of the air guide bladder.

[0010] Furthermore, the leak repair tube is detachably connected to the handheld part, and a sealing cap is provided at the port of the receiving cavity when the leak repair tube is removed; The leak repair pipe port is integrally formed with a guide plate, which is arc-shaped and used to guide the leak repair fluid to the pipe.

[0011] Furthermore, the side wall of the receiving cavity is connected to an injection channel, which is located close to the leak repair pipe, and the leak repair fluid is injected into the receiving cavity from the injection channel; a sealing plug is also provided in the injection channel.

[0012] Furthermore, the volume of the sealant fluid loaded in the receiving cavity is no more than 1 / 3 of the volume of the receiving cavity.

[0013] Furthermore, a limiting groove is provided on the side of the air bladder away from the leak repair tube, and the limiting groove is located on the side near the free end of the air bladder. A water-blocking sticker is placed inside the limiting slot, and the water-blocking sticker is used to stick to the leak in the pipe.

[0014] Furthermore, the inflation pump and the inflation channel are partially threaded together, and the end of the inflation pump is provided with a sealing rubber head.

[0015] Furthermore, a rapid deflation channel is provided on the side wall of the inflation channel.

[0016] The present invention can achieve the following beneficial effects: 1. The leak repair device of this application squeezes out the leak repair liquid through the leak repair tube, which can extend the application height of the leak repair device, thereby facilitating maintenance personnel to perform temporary leak repair; in addition, the guide airbag can extend the transmission path of the leak repair liquid, so that the leak repair device of this application can repair leaks on pipes at higher heights, and the leak repair airbag can also be retracted for storage.

[0017] 2. When using a leak repair pipe for pipe repair, install the coating guide to the end of the leak repair pipe. When the leak repair liquid is squeezed out, the leak repair liquid can be squeezed onto the pipe surface through the guide plate. At the same time, the leak repair liquid can also be spread evenly through the guide plate, thereby realizing the leak repair operation of high-altitude pipes.

[0018] 3. A water-blocking sticker is placed at the bottom of the leak-sealing airbag, so that the leak-sealing device of this application can be used to repair leaks on different sides of the pipe. That is, for leaks at the bottom of the pipe, the leak-sealing liquid can be squeezed onto the pipe surface through the leak-sealing pipe to achieve leak sealing. For areas where it is inconvenient to apply the leak-sealing liquid, the water-blocking sticker can be delivered to the periphery of the pipe through the leak-sealing airbag, and the water-blocking sticker can be pasted by the retraction of the leak-sealing airbag.

[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0022] like Figures 1 to 3 As shown, a temporary leak repair device for a pipe includes a handheld part 1, and a receiving cavity 11 for loading repair fluid is formed inside the handheld part 1. The outlet end of the receiving cavity 11 is connected to a repair pipe 2, and the other end is inserted with a push rod 3. When it is necessary to output the repair fluid, the push rod 3 is pushed, and the push rod 3 will generate an axial thrust on the repair fluid in the receiving cavity 11, so that the repair fluid flows along the communication path between the receiving cavity 11 and the repair pipe 2, and finally flows out from the end of the repair pipe 2.

[0023] A guide plate 21 is integrally formed at the end of the leak repair pipe 2. The guide plate 21 is arc-shaped and is used to accurately deliver the leak repair fluid to the leak. When the push rod 3 is pushed to make the leak repair fluid flow out of the leak repair pipe 2, the leak repair fluid will first come into contact with the guide plate 21. Under the guidance of the guide plate 21, it will flow accurately to the leak in the pipe. At the same time, the guide plate 21 can scrape the leak repair fluid evenly on the pipe surface, ensuring that the leak repair fluid evenly covers the leak area and avoids local accumulation of leak repair fluid, which will affect the leak repair effect.

[0024] The side wall of the receiving cavity 11 is also connected to an injection channel 13. A sealing plug 14 is installed in the injection channel 13. The inspection personnel can remove the sealing plug 14 and inject the leak repair fluid into the receiving cavity 11 through the injection channel 13. After the injection is completed, the sealing plug 14 is reinstalled to ensure the sealing of the receiving cavity 11. The injection channel 13 is located close to the leak repair pipe 2, and the amount of leak repair fluid injected is no more than 1 / 3 of the volume of the receiving cavity 11. By setting a small amount of leak repair fluid, the moving area of ​​the push rod 3 is large. After the leak is repaired with the leak repair fluid, there is enough space to pull the push rod 3 backward, so that the leak repair fluid flows back from the leak repair pipe 2 into the receiving cavity 11 under negative pressure.

[0025] The repair tube 2 and the handle 1 are detachably connected. Specifically, a connecting end tube protrudes from the end face of the handle 1 and communicates with the receiving cavity 11. The repair tube 2 is threaded onto the connecting end tube. When the repair tube 2 is removed, a sealing cap is provided to seal the connecting end tube. After the repair is completed, the push rod 3 can be pulled back to allow all the repair fluid to flow back into the receiving cavity 11. At this time, the repair tube 2 can be removed and the sealing cap installed to achieve sealed storage of the repair fluid. To prevent the repair tube 2 from being easily lost after removal, a storage tube for holding the repair tube 2 can be provided on the side wall of the handle 1. The storage tube is not shown in the figure.

[0026] The leak-sealing pipe 2 extends the outlet path of the leak-sealing fluid, allowing inspectors to precisely repair leaks in pipes approximately one meter overhead. Simultaneously, when repairing leaks in pipes closer to the ground, repairs can be completed without excessive bending or approaching the pipe, significantly improving operational convenience. It is important to emphasize that this leak-sealing device is only a temporary solution; it only temporarily blocks water flow and is not the final repair. Further pipe repair will be carried out once professional maintenance personnel arrive on-site.

[0027] A guide airbag 4 for transporting repair fluid is also provided at the end of the handheld part 1. The guide airbag 4 and the repair tube 2 are two independent repair fluid transport paths. When the repair fluid is transported using the repair tube 2, the guide airbag 4 can be stored. When the repair fluid is transported using the guide airbag 4, the repair tube 2 can be disassembled.

[0028] Specifically, a liquid guide tube 41 is fixed to the side of the air bladder 4 facing the leak repair tube 2. The liquid guide tube 41 extends along the length of the air bladder 4 and is a flexible tube, allowing it to fold along with the air bladder 4. One end of the liquid guide tube 41 is detachably connected to the connecting end cylinder, and the other end extends out of the end of the air bladder 4. When the liquid guide tube 41 is connected to the receiving cavity 11, pushing the push rod 3 can deliver the leak repair fluid along the liquid guide tube 41 to the leak repair point to achieve leak repair. The fact that one end of the liquid guide tube 41 extends out of the end of the air bladder 4 makes it less likely for the leak repair fluid to drip onto the air bladder 4, reducing the possibility of contamination of the air bladder 4.

[0029] To enable the inflation and retraction of the airbag 4, an inflation channel 12 is provided inside the handheld part 1. The inflation channel 12 is connected to the airbag 4, and an inflation pump 5 is provided inside the inflation channel 12. Pushing the inflation pump 5 can inflate and unfold the airbag 4, and pulling back the inflation pump 5 can retract the airbag 4.

[0030] The flow-guiding airbag 4 is suitable for pipe leak repair at a height of about 3 meters. The flow-guiding airbag 4 can further extend the flow path of the leak repair fluid. It should be noted that the diameter of the liquid guide tube 41 is smaller than the diameter of the leak repair tube 2, which makes it easier for the leak repair fluid to move a longer path.

[0031] In another embodiment, a limiting groove 42 is formed on the side of the air bladder 4 facing away from the liquid guiding tube 41. The limiting groove 42 is located near the free end of the air bladder 4 and is part of the air bladder 4. Inflation can support the limiting groove 42. When the gas in the air bladder 4 is released, the limiting groove 42 can be folded and stored. A water-blocking sticker 6 for pasting to the leaking part of the pipe can be placed in the limiting groove 42. In this embodiment, the section of the inflation channel 12 near the outside is provided with a threaded section. The inflation pump 5 is threadedly connected to the threaded section of the inflation channel 12, and the end of the inflation pump 5 is also provided with a sealing rubber head 51.

[0032] For locations where it's inconvenient to apply sealant at the top or bottom of the pipe, temporary leak sealing stickers 6 can be used. Specifically, first, turn the knob on the inflation pump 5 until the air guide 4 gradually expands. The threaded connection structure can fix the position of the inflation pump 5 after inflation, requiring no manual control. The sealing rubber head 51 at the end of the inflation pump 5 prevents gas leakage, allowing the air guide 4 to expand smoothly. After the air guide 4 expands, the leak sealing sticker 6 can be placed in the limiting slot 42. Use the air guide 4 to align the leak sealing sticker 6 with the leak. The side wall of the inflation channel 12 also has a quick release channel 15. After the leak sealing sticker 6 is aligned with the leak, open the quick release channel 15 to release the gas in the air guide 4.

[0033] The design of the air-guiding bladder 4 incorporates a restoring force when it curls into a disc shape. When air is blown into the air-guiding bladder 4, it straightens from its disc shape. When the air is expelled, the air-guiding bladder 4 automatically returns to its disc shape. Furthermore, when the water-blocking sticker 6 is aligned with the leak, the quick-release channel 15 is opened. At this point, the air-guiding bladder 4 returns to its disc shape, guiding the water-blocking sticker 6 to adhere to the pipe sidewall to achieve water blocking. The limiting groove 42 only limits the water-blocking sticker 6 to prevent it from falling off during the upward delivery process using the air-guiding bladder 4. Once the water-blocking sticker 6 adheres to the pipe surface, the adhesion force is greater than the limiting force of the limiting groove 42, allowing the water-blocking sticker 6 to separate from the surface of the air-guiding bladder 4 after it unfolds again.

[0034] This application's temporary leak repair device includes a leak repair pipe 2 for conveying leak repair fluid, a liquid guide pipe 41 for conveying leak repair fluid, and a guide airbag 4 for attaching a water-blocking sticker 6 to achieve temporary leak repair of the pipeline. It can meet three different leak repair methods to achieve temporary leak repair of pipelines at different heights and angles. The overall structure is simple and easy to operate.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
