Description

[0001] The present application relates to the technical field of pipeline testing, and more specifically, to a pipeline leakage monitoring device and a monitoring method thereof. Background Art

[0002] Pipes are common in our daily lives and have a wide range of uses. They are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations. With the development of the times, there are many types of pipe materials. When pipes leak, it is easy to cause a large amount of water resources waste, so staff need to use detection devices to detect the pipes.

[0003] Regarding the above-mentioned related technologies, the applicant believes that when the current pipeline leakage monitoring device is in use, the two ends of the pipeline are usually connected to the device, and then the pipeline is pressurized by a pressure pump. The pipeline can be monitored by observing the value on the pressure gauge to confirm whether the pipeline is broken and leaking. Currently, when the pipeline is connected to the device, bolts and nuts are usually used for connection. Although the pipeline can be stably connected, this method of connection and disassembly takes a lot of time, so the device is not convenient for quick replacement of pipelines for monitoring, which affects the use of the device.

Then, the pressure pump 150 is turned off. The staff can monitor the inspected pipeline 170 by observing the value on the monitoring pressure gauge 160 to confirm whether the inspected pipeline 170 has any water leakage.

[0044] S3. Turning on the drive motor 310 can drive the transmission gear 322 to rotate. When the transmission gear 322 rotates, it will drive the two racks 321. The racks 321 will drive the translation platform 130 to slide inside the movable groove 120, thereby adjusting the positions of the two pressure tanks 140 to facilitate monitoring of inspected pipes 170 of different lengths.

The four insertion rods 250 will be inserted into the connecting pipe 210 and contact the rubber sealing ring 283 for sealing. The first spring 262 is expanded and the second spring 273 is contracted to expand the first spring 262, thereby driving the clamping block 261 to descend and clamp to the outer surface of the insertion rod 250, thereby connecting one end of the pipe. The movable ring 272 is pushed again to lift the clamping block 261 again, and then the inspected pipe 170 is pulled outward to drive the connecting pipe to be pulled out, and the sealing ring 282 is withdrawn from the annular groove 281 to release the connection, so that the inspected pipe 170 can be easily connected and disassembled when it needs to be monitored. The driving motor 310 is turned on to drive the transmission gear 322 to rotate. The transmission gear 322 will drive the two racks 321 when rotating. The racks 321 will drive the translation platform 130 to slide inside the movable groove 120, thereby adjusting the positions of the two pressure tanks 140 to facilitate monitoring of the inspected pipes 170 of different lengths. At the same time, the first bevel gear 323 will drive the bidirectional screw rod 331 to rotate through the second bevel gear 332, thereby moving the two translation plates 333 closer to each other, so that the two push rods 3 34 pushes the bottom plate 340 down, and when the two pressure tanks 140 are completely retracted and brought close together so that monitoring cannot be carried out, the four moving wheels will touch the ground, making it easier to move the device. After both ends of the inspected pipeline 170 are connected, the pressure pump 150 can be turned on to pressurize the two pressure tanks 140 and the inside of the inspected pipeline 170. Thereafter, the pressure pump 150 is turned off, and the staff can monitor the inspected pipeline 170 by observing the value on the monitoring pressure gauge 160 to confirm whether the inspected pipeline 170 has any water leakage.

7. A pipeline water leakage monitoring method according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1. By pushing the moving ring (272) to slide inside the slide groove (271) and pulling the second spring (273), the moving ring (272) will push the clamping block (261) to lift and press the first spring (262) to shrink through the connecting rod (263), and then insert the connecting pipe at one end of the inspected pipe (170) into the interior of the connecting pipe (210) to collide with the conflicting ring (220), and at the same time, the sealing ring (282) is inserted into the interior of the annular groove (281) and collides with the rubber sealing ring (283) for sealing, and the four insertion rods (250) will be respectively inserted into the interior of the four limiting grooves, and then the moving ring (272) is loosened, so that the second spring (273) shrinks and the first spring (262) expands, thereby driving the clamping block (261) to descend and be clamped to the outer surface of the insertion rod (250), thereby fixing one end of the inspected pipe (170), and then fixing the other end of the inspected pipe (170); S2. After both ends of the inspected pipeline (170) are connected, the pressure pump (150) is turned on to pressurize the two pressure tanks (140) and the interior of the inspected pipeline (170). The pressure pump (150) is then turned off. The staff can monitor the inspected pipeline (170) by observing the value on the monitoring pressure gauge (160) to confirm whether the inspected pipeline (170) has any water leakage; S3. Turning on the driving motor (310) can drive the transmission gear (322) to rotate. When the transmission gear (322) rotates, it will drive the two racks (321). The racks (321) will drive the translation platform (130) to slide inside the movable groove (120), thereby adjusting the positions of the two pressure tanks (140) to facilitate monitoring of inspected pipes (170) of different lengths. At the same time, the first bevel gear (323) will drive the bidirectional screw (331) to rotate through the second bevel gear (332), thereby allowing the two translation plates (333) to move closer to each other, thereby allowing the two push rods (334) to push the bottom plate (340) down. When the two pressure tanks (140) are completely retracted and brought close together and cannot be used for monitoring, the four moving wheels will contact the ground; S4. Pushing the movable ring (272) again can drive the clamping block (261) to be lifted again, and then pulling the inspected pipe (170) outward can drive the connecting pipe to be drawn out, and the sealing ring (282) is withdrawn from the annular groove (281), thereby releasing the connection of the inspected pipe (170), making it easier to disassemble and assemble the inspected pipe (170).
