Description

Technical Field

[0001] This utility model belongs to the field of pipeline monitoring, and in particular relates to a vibration monitoring device for underground pipelines. Background Technology

[0002] In vibration monitoring of buried pipelines, the method of fixing the vibration monitor directly affects the accuracy and long-term stability of the monitoring data. Currently, the common fixing method is using clamps. Clamp fixing facilitates later maintenance of the monitoring device. However, clamp fixing involves using multiple sets of bolts and nuts to fasten the vibration sensor to the outer wall of the pipeline. Manually installing multiple bolts and nuts is too cumbersome and reduces work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a vibration monitoring device for underground pipelines to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of the buried pipeline vibration monitoring device of this utility model is as follows: A vibration monitoring device for buried pipelines includes a mounting shell with a downward-facing mounting groove. A base plate is detachably attached to the bottom of the mounting shell via a connector, and a vibration monitor for pipeline monitoring is mounted on the base plate. Locking arms are symmetrically arranged along their longitudinal centerline within the mounting groove, and are rotatably connected to the mounting shell via a pivot. A transmission unit is provided on the mounting shell, connecting to the two locking arms. Driving the transmission unit allows the two locking arms to move relative to each other, enabling fixation and disassembly on the pipeline. Rubber sealing tubes are provided on both sides of the mounting shell, with the other end of each sealing tube connected to a locking arm.

[0005] Furthermore, a placement groove is formed in the middle of the locking arm near the mounting housing, and a through hole extending downward and communicating with the mounting groove is formed on the top surface of the mounting housing. The transmission part includes worm gears disposed in each placement groove, and each worm gear is connected to its corresponding rotating shaft. A support block is provided in the mounting groove, and a worm gear meshing with two worm gears is rotatably mounted on the support block. A connecting shaft that movably engages with the through hole is provided on the top surface of the worm gear, and an inner hole is formed at the top end of the connecting shaft for inserting a tool and driving it to rotate.

[0006] Furthermore, the support block and the side wall of the mounting groove are slidably connected, and the side wall of the mounting groove has a guide groove for the support block to slide, and a spring is provided between the support block and the base plate.

[0007] Furthermore, the support block has a first insertion hole at one end and a second insertion hole on one side of the mounting shell, and a pin is inserted into the second insertion hole, which can be inserted into the first insertion hole.

[0008] Furthermore, a hanging ring is provided at the outer end of the pin.

[0013] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a vibration monitoring device for underground pipelines.

[0014] like Figures 1 to 3 As shown, this utility model discloses a vibration monitoring device for underground pipelines, comprising a mounting shell 1 with a downward-facing mounting groove 2. A base plate 9 is detachably attached to the bottom of the mounting shell 1 via a connector (screw or bolt). A vibration monitor 10 for monitoring the pipeline is mounted on the base plate 9. Locking arms 4 are symmetrically arranged along their longitudinal centerline within the mounting groove 2, and are rotatably connected to the mounting shell 1 via a rotating shaft. A transmission unit is provided on the mounting shell 1, connected to the two locking arms 4. By driving the transmission unit, the two locking arms 4 can move relative to each other, thereby achieving the purpose of locking and unlocking the pipeline. When the locking arms 4 lock the pipeline, the vibration monitor 10 mounted on the base plate 9 is fixed to the pipeline. The vibration monitor 10 is electrically connected to a central control unit, allowing for monitoring of the pipeline vibration. Of course, when maintenance of the vibration monitor 10 is required, the device can be easily and quickly removed from the pipeline by driving the transmission unit to open the locking arms 4.

[0015] like Figure 2 As shown, a placement groove is formed in the middle of the locking arm 4 near the mounting housing 1, and a through hole 7 extending downward and communicating with the mounting groove 2 is formed on the top surface of the mounting housing 1. The transmission part for connecting the two locking arms 4 includes a worm gear 3 provided in each placement groove, and each worm gear 3 is connected to its corresponding rotating shaft. That is, when the worm gear 3 rotates, the locking arm 4 connected to the worm gear 3 through the rotating shaft will also rotate.

[0016] Still Figure 2 As shown, a support block 11 is provided in the mounting groove 2, and a worm 5 that meshes with two worm gears 3 is rotatably mounted on the support block 11. A connecting shaft that movably engages with a through hole 7 is provided on the top surface of the worm 5, and an inner hole is opened at the top of the connecting shaft for inserting a tool and driving it to rotate. A tool corresponding to the inner hole is connected to the inner hole, and then the tool drives the connecting shaft. The rotation of the connecting shaft drives the worm 5 to rotate, and when the worm 5 rotates, the worm gear 3 that meshes with it also rotates. At this time, the locking arm 4 connected to the worm gear 3 also rotates, thus achieving the purpose of relative movement of the two locking arms 4. That is, the two locking arms 4 achieve relative unfolding and closing through their respective corresponding rotating shafts, and achieve the fixation and disassembly of the pipeline during the unfolding and closing of the two locking arms 4. The worm gears 3 and worm 5 are designed with a self-locking function to prevent the locking arms 4 from loosening due to pipeline vibration. The inner hole for connecting the tool is preferably an internal hexagonal hole 6, but other inner holes can also be used; no further restrictions are placed here.

[0017] Preferably, the support block 11 and the side wall of the mounting groove 2 are slidably connected, and the side wall of the mounting groove 2 has a guide groove for the support block 11 to slide. A spring 12 is provided between the support block 11 and the base plate 9. When the tool is removed from the inner hole of the connecting shaft, the spring 12 will apply an upward thrust to the worm 5 through the support block 11. Due to the meshing of the worm wheel 3 and the worm 5, the worm 5 will push the locking arm 4 to rotate downward, so that the locking arm 4 is continuously locked to the pipeline. Of course, if the worm 5 rotates due to the vibration of the pipeline, the spring 12 will also supplement the rotation of the worm 5, so that the locking arm 4 continuously locks the pipeline.

[0018] As another preferred embodiment, the support block 11 has a first insertion hole 13 at one end and a second insertion hole 17 on one side of the mounting housing 1, with a pin 14 inserted into the second insertion hole 17. The pin 14 can also be inserted into the first insertion hole 13. When the pin 14 is inserted into the first insertion hole 13 of the support block 11, the support block 11 is fixed within the mounting housing 1. At this point, rotating the transmission unit with a tool allows for better securing of the locking arm 4 to the pipe. After the locking arm 4 locks the pipe, the pin 14 can be removed from the first insertion hole 13, and the spring 12 applies a pushing force to the worm gear 5 through the support block 11. When the vibration monitoring device needs to be disassembled later, the pin 14 can be reinserted into the first insertion hole 13 to reset the support block 11, and then the transmission unit can be rotated with a tool. Specifically, the inner end of the pin 14 is tapered. To facilitate pulling the pin 14, a hanging ring 15 is provided at the outer end of the pin 14.

[0019] As a further improvement, a protective cover 8 is rotatably mounted on the top surface of the mounting shell 1 via a pin, and the protective cover 8 can seal the through hole 7. By rotating the protective cover 8 and aligning it with the through hole 7, the protective cover 8 can seal the through hole 7, preventing soil from entering it. To release the seal of the through hole 7, simply rotate the protective cover 8 to the position of the through hole 7. Additionally, rubber sealing tubes 16 are provided on both sides of the mounting shell 1, with the other end of each tube connected to the locking arm 4. When the locking arm 4 rotates, the rubber sealing tubes 16 deform accordingly without affecting the normal rotation of the locking arm 4. The rubber sealing tubes 16 prevent soil from entering the mounting groove 2 and affecting its interior.

[0020] Instructions for use: Rotate the protective cover 8 to disengage it from the through hole 7. Then, use a tool to connect it to the inner hole of the connecting shaft and rotate the connecting shaft. This rotation causes the worm gear 5 to rotate, which in turn drives the worm wheel 3, causing the locking arm 4 on the worm wheel 3 to unfold and adapt to the outer diameter of the pipe. Next, place the vibration monitor 10 against the pipe. Then, use the tool to rotate the connecting shaft in the opposite direction. This will also cause the worm gear 5 on the connecting shaft to rotate in the opposite direction, bringing the two locking arms 4 closer together until they clamp and fix the pipe in place. Finally, use the hanging ring 15 to pull the pin 14 off the support block 11.
