Description

Technical Field

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

[0002] Pipeline repair refers to the use of various techniques to restore damaged or leaking pipelines to their normal function. To reduce the difficulty of construction during pipeline repair, trenchless repair methods are typically employed, effectively minimizing excavation work and the impact on the pipeline installation site.

[0003] During long-term use, some deposits will adhere to the inner wall of the pipe. When the pipe is damaged and needs to be repaired, directly spraying pipe repair fluid onto the inner wall of the pipe will cause the repair fluid to only adhere to the deposits on the inner wall of the pipe. However, the structure of the deposits is not stable and will fall off under the long-term impact of the liquid inside the pipe. This will affect the repair effect and cause the pipe to leak again. Utility Model Content

[0004] The purpose of this application is to provide a trenchless pipeline repair device to solve the problem mentioned in the background art: during long-term use, some deposits will adhere to the inner wall of the pipeline. When the pipeline is damaged and needs repair, directly spraying the pipeline repair fluid onto the inner wall of the pipeline will cause the repair fluid to only adhere to the deposits on the inner wall of the pipeline. However, the structure of the deposits is not stable and will fall off under the long-term impact of the liquid inside the pipeline. This will affect the repair effect of the pipeline and cause the pipeline to leak again.

[0005] To achieve the above objectives, this application provides the following technical solution: a trenchless pipeline repair device, comprising a remote-controlled vehicle, a camera mounted on the remote-controlled vehicle for acquiring images of the inside of the pipeline, a cleaning component mounted on the front of the remote-controlled vehicle for removing deposits from the inner wall of the pipeline, and a repair component mounted on the top of the remote-controlled vehicle for repairing damaged parts of the pipeline. The cleaning assembly includes a carrier plate mounted on the front of the remote-controlled vehicle, and a first motor mounted on the carrier plate. The output shaft of the first motor is connected to a carrier block via a coupling. An electric push rod is mounted on the carrier block. A support rod is fixedly mounted on the output end of the electric push rod, and a scraper is fixedly mounted on the other end of the support rod.

[0006] Furthermore, the remote-controlled vehicle is equipped with two supplementary lights, which are located on both sides of the camera.

[0007] Furthermore, the repair component includes a storage tank and a pump, both of which are mounted on the top of the remote-controlled vehicle. The pump's inlet is connected to the storage tank, and the pump's outlet is fixedly connected to a delivery pipe. A hydraulic rotary joint is installed at the other end of the delivery pipe, and an infusion pipe is installed at the other end of the hydraulic rotary joint. A nozzle is installed at the other end of the infusion pipe, and a first gear is fixedly sleeved on the outside of the infusion pipe. A drive assembly is installed on the pump, which drives the first gear to rotate.

[0008] Furthermore, the infusion tube is an "L" shaped tube.

[0011] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, a camera is used to capture images of the inside of the pipe, which makes it easier for the staff to operate the scraper driven by the first motor to rotate to face the damaged position of the pipe. With the help of the electric push rod, the scraper is pushed to move closer to the pipe wall. As the scraper driven by the first motor rotates back and forth, it completes the cleaning work of the damaged position of the pipe wall layer by layer in an orderly manner. This ensures that the attachments on the pipe wall are removed as much as possible, which is conducive to the effective repair of the pipe damage by the subsequent repair components and reduces the probability that the pipe repair fluid will peel off along with the pipe attachments.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: Reference Figure 1-4 The device shown is a trenchless pipeline repair device, including a remote-controlled vehicle 1. A camera 2 is mounted on the remote-controlled vehicle 1 for capturing images of the inside of the pipeline. Two supplementary lights 9 are mounted on the remote-controlled vehicle 1, positioned on either side of the camera 2, to provide supplementary lighting for the images captured by the camera 2, making the images clearer and more accurate. A cleaning component is mounted on the front of the remote-controlled vehicle 1 for removing deposits from the inner wall of the pipeline. A repair component is mounted on the top of the remote-controlled vehicle 1 for repairing damaged sections of the pipeline. A cable is mounted on the remote-controlled vehicle 1, with the other end of the cable connected to a controller. The controller controls the movement of the remote-controlled vehicle 1 and the operation of the cleaning and repair components as needed. The image information captured by the camera 2 can be displayed in real time on a monitor on the controller, thus facilitating timely control of the device by personnel for repairing damaged sections of the pipeline.

[0018] The cleaning component includes a carrier plate 3, which is installed on the front side of the remote control vehicle 1. A first motor 4 is installed on the carrier plate 3. The output shaft of the first motor 4 is connected to a carrier block 5 through a coupling. An electric push rod 6 is installed on the carrier block 5. A support rod 7 is fixedly installed at the output end of the electric push rod 6. A scraper 8 is fixed at the other end of the support rod 7. Camera 2 captures images of the inside of the pipe, allowing staff to control the scraper 8 driven by the first motor 4 to rotate to face the damaged area of ​​the pipe. With the help of the electric push rod 6, the scraper 8 is pushed closer to the pipe wall, so that the scraper 8 driven by the first motor 4 completes the cleaning work of the damaged area of ​​the pipe wall layer by layer in an orderly manner during the back and forth rotation, ensuring that the attachments on the pipe wall are removed as much as possible.

[0019] The repair component includes a storage tank 10 and a pump 11. Both the storage tank 10 and the pump 11 are installed on the top of the remote control vehicle 1. The inlet of the pump 11 is connected to the storage tank 10, and the outlet of the pump 11 is fixedly connected to a delivery pipe 12. A hydraulic rotary joint 13 is installed at the other end of the delivery pipe 12, and an infusion pipe 14 is installed at the other end of the hydraulic rotary joint 13. The infusion pipe 14 is an "L" shaped pipe. In order to make the spray direction of the nozzle 15 face the inner wall of the pipe, a nozzle 15 is installed at the other end of the infusion pipe 14, and a first gear 16 is fixedly sleeved on the outside of the infusion pipe 14. A drive component is installed on the pump 11 to drive the first gear 16 to rotate. A replenishment pipe 17 is fixedly connected to the top of the storage tank 10. A sealing cap 18 is threadedly connected to the top of the replenishment pipe 17. By unscrewing the sealing cap 18, the pipe repair fluid can be injected into the interior of the storage tank 10 along the replenishment pipe 17 to facilitate the use of the pipe repair fluid. The drive assembly includes a second motor 19, which is mounted on the pump 11. The output shaft of the second motor 19 is connected to a transmission rod 20 via a coupling. The other end of the transmission rod 20 is fixed with a second gear 21, which meshes with the first gear 16. The second motor 19 drives the second gear 21 to rotate, and the second gear 21 pulls the first gear 16 to rotate, so that the first gear 16 drives the infusion tube 14 and the nozzle 15 to rotate. In this way, the nozzle 15 can rotate to face the damaged position of the pipeline. Then, under the operation of the pump 11, the pipeline repair fluid in the storage tank 10 can be sprayed out along the nozzle 15 to cover the damaged position of the pipeline and complete the pipeline repair work.

[0020] Working principle of this utility model: The staff placed the remote control car 1 inside the pipe and used the controller to move the remote control car 1 in the pipe. After the two auxiliary lights 9 were powered on, they could illuminate the inside of the pipe. In this way, the camera 2 captured a clearer image of the inside of the pipe, which made it easier for the staff to remotely check the inside of the pipe until the location of the pipe damage was found. Once camera 2 detects the location of the pipe rupture, remote control vehicle 1 is slowly moved until scraper 8 and the rupture location are on the same vertical plane. The movement of remote control vehicle 1 is then paused, and first motor 4 is used to drive scraper 8 to rotate, so that scraper 8 cleans the inner wall of the pipe. The staff repeatedly operates electric push rod 6, so that scraper 8 pushed down by electric push rod 6 can scrape off the deposits on the inner wall of the pipe layer by layer until the cleaning work of the rupture location is completed. The staff used the controller to move the remote control vehicle 1 forward again, so that the nozzle 15 was moved to the same vertical plane as the damaged pipe. The staff stopped the movement of the remote control vehicle 1 and operated the second motor 19 to drive the second gear 21 to rotate. The second gear 21 pulled the first gear 16 to rotate, so that the first gear 16 drove the infusion tube 14 and the nozzle 15 to rotate. In this way, the nozzle 15 could be rotated to face the damaged pipe. Then, the staff operated the pump 11 to send the pipe repair fluid in the storage tank 10 to the infusion tube 14, so that the pipe repair fluid was finally sprayed along the nozzle 15 to the damaged pipe, completing the pipe repair work.
