Description

Technical Field

[0001] This utility model belongs to the field of monitoring technology, specifically relating to a detachable pipeline vibration sensor array mounting base. Background Technology

[0002] In oil transportation systems, oil pipelines serve as critical transport facilities, and their installation methods are mainly divided into underground burial and overhead installation. It is worth noting that during long-term operation, overhead pipelines experience continuous mechanical vibrations in their supporting structures due to the periodic impact forces generated by the internal fluid flow. This long-term vibration effect can lead to two main problems: firstly, accelerated wear at the contact points between the pipeline and the supporting structure; and secondly, accumulated fatigue damage to connecting components. If this results in a pipeline rupture and leakage, it could trigger a serious environmental pollution incident. To ensure the safe operation of oil pipelines, monitoring devices are installed at critical locations. By collecting and analyzing parameters such as vibration frequency and amplitude in real time, potentially high-risk pipeline sections can be accurately identified, preventing possible leaks and environmental hazards. However, disassembling existing vibration detection devices is extremely cumbersome when the detection location needs to be changed. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1:

[0018] The detachable pipeline vibration sensor array mounting base provided by this utility model includes a fixing sleeve 1, which includes a first assembly 2 and a second assembly 3. The first assembly 2 and the second assembly 3 are movably connected by a rotating shaft structure 4. The first assembly 2 has a protrusion 5, and a locking mechanism 7 is fixedly installed on the protrusion 5 by bolts 6. The protrusion 5 has a slot 8. The locking mechanism 7 includes a fixing seat 9 and a lock head 10. The fixing seat 9 has a guide groove 11 aligned with the slot 8 and an insertion hole 12. The lock head 10 has an insertion rod 13. The second assembly 3 has a snap-fit ​​part 14. A vibration monitoring unit 15 is fixedly installed on the fixing sleeve 1. The slot 8 has a bevel 16. The snap-fit ​​part 14 has a T-shaped design. Both the first assembly 2 and the second assembly 3 are fixedly installed with rubber pads 17. The rubber pads 17 are made of polyurethane rubber.

[0019] Through the above technical solution, the present invention fixes a vibration monitoring unit 15 on the fixed sleeve 1. The fixed sleeve 1 includes a first assembly 2 and a second assembly 3. The first assembly 2 and the second assembly 3 are movably connected by a rotating shaft structure 4. In use, the first assembly 2 and the second assembly 3 are opened and fitted onto the pipe surface. The snap-fit ​​part 14 of the second assembly 3 is snapped into the snap groove 8 of the first assembly 2. Then, the plug rod 13 of the lock head 10 is inserted into the socket 12 to lock the snap-fit ​​part 14 in the snap groove 8 and lock the lock head 10, thus quickly completing the installation operation. When disassembly is required, the key is inserted into the lock head 10 to unlock the lock head 10, and the plug rod 13 and the snap-fit ​​part 14 are pulled out to open the first assembly 2 and the second assembly 3, thus quickly completing the disassembly and improving work efficiency.

[0020] Example 2:

[0021] In the routine maintenance of oil pipelines, when technicians need to monitor the vibration of a specific pipe section, they first unfold the first assembly 2 and the second assembly 3 of the fixing sleeve 1 along the rotating shaft structure 4 to form an open state. At this time, the technicians wrap the unfolded fixing sleeve 1 around the outer surface of the pipe to be monitored, ensuring good contact between the pipe and the inner wall of the fixing sleeve 1. Subsequently, the operator aligns the snap-fit ​​part 14 of the second assembly 3 with the slot 8 on the protrusion 5 of the first assembly 2, and manually applies pressure to make the snap-fit ​​part 14 fully embedded in the slot 8.

[0022] Once the locking part 14 is in place, the technician removes the locking mechanism 7 and aligns the guide groove 11 on the fixing seat 9 with the corresponding structure on the protrusion 5, ensuring the fixing seat 9 is stably installed on the surface of the protrusion 5. At this time, the insertion hole 12 on the fixing seat 9 and the slot 8 maintain a coaxial position. The operator aligns the insertion rod 13 on the lock head 10 with the insertion hole 12 and applies appropriate pressure to ensure the insertion rod 13 completely passes through the insertion hole 12, achieving mechanical locking of the locking part 14. Finally, the locking function of the lock head 10 ensures that the insertion rod 13 will not accidentally come out, completing the entire installation process.

[0023] After the vibration monitoring task is completed, technicians use a special key to unlock the lock 10 and completely pull the insertion rod 13 out of the insertion hole 12. At this time, the mechanical constraint between the locking part 14 and the locking groove 8 is released, and the operator can easily separate the second assembly 3 from the first assembly 2, allowing the fixing sleeve 1 to return to its unfolded state, thus facilitating the removal of the entire mounting base from the pipeline. This design is particularly suitable for occasions requiring frequent changes in monitoring positions, greatly improving work efficiency.

[0024] In this embodiment, the vibration monitoring unit 15 is stably connected to the pipeline via the fixing sleeve 1, enabling accurate acquisition of pipeline vibration signals. When the pipeline vibrates due to fluid flow, the vibration energy is transmitted to the monitoring unit through the fixing sleeve 1, and converted into an electrical signal output by the sensor inside the monitoring unit. Technicians can determine the pipeline's operating status based on the monitoring data and promptly detect abnormal vibrations.

[0025] The detachable nature of the mounting base (fixed sleeve 1) allows the monitoring equipment to be transferred between different pipe sections, saving equipment costs and improving monitoring flexibility.

[0026] Example 3:

[0027] In this embodiment, the fixing sleeve 1 adopts a split design, consisting of a first assembly 2 and a second assembly 3, which are movably connected by a pivot structure 4. This split design allows the mounting base to be opened and closed quickly, facilitating installation and disassembly operations on pipelines.

[0028] The first assembly 2 has a protrusion 5, which is fixedly mounted with a locking mechanism 7 by bolts 6. The protrusion 5 has a slot 8 with a specific bevel 16 design. The locking mechanism 7 consists of a fixing base 9 and a lock head 10. The fixing base 9 has a guide groove 11 aligned with the slot 8 and an insertion hole 12, while the lock head 10 has an insertion rod 13. The second assembly 3 has a corresponding engaging part 14 that mates with the slot 8 on the first assembly 2. The bevel 16 design of the slot 8 allows the engaging part 14 to slide more easily into the slot 8, achieving quick alignment and engagement.

[0029] In actual installation, the operator first opens the first assembly 2 and the second assembly 3, and then places the fixing sleeve 1 onto the surface of the pipe to be monitored. Due to the inclined surface 16 design of the groove 8, the snap-fit ​​part 14 of the second assembly 3 can smoothly slide into the groove 8 of the first assembly 2 along the inclined surface 16. After the snap-fit ​​part 14 is fully inserted into the groove 8, the operator inserts the insertion rod 13 of the locking head 10 into the insertion hole 12 of the fixing base 9, and the locking mechanism 7 securely locks the snap-fit ​​part 14 into the groove 8. Finally, the locking head 10 is locked to complete the entire installation process. This design greatly simplifies the installation steps and improves work efficiency.

[0030] When it is necessary to disassemble or replace the monitoring position, the operator only needs to use a special key to unlock the lock 10, pull out the insertion rod 13, and then gently pull the second assembly 3 to disengage the locking part 14 from the slot 8. Due to the inclined surface 16 design of the slot 8, the locking part 14 can slide smoothly out of the slot 8 without any jamming. Then the first assembly 2 and the second assembly 3 can be easily opened to complete the disassembly operation. The whole process is simple and quick, without the need for complicated tools or cumbersome operations.

[0031] Example 4:

[0032] In this embodiment, the locking part 14 adopts a T-shaped design. This T-shaped locking part 14 consists of a laterally extending locking crossbeam and a longitudinally extending locking vertical beam, with both ends of the crossbeam extending beyond the width of the vertical beam. When the first assembly 2 and the second assembly 3 are closed, the locking vertical beam of the T-shaped locking part 14 first inserts into the locking groove 8 provided in the protrusion 5 of the first assembly 2. At this time, both ends of the crossbeam abut against the surfaces of the protrusions 5 on both sides of the groove 8. As the closing action continues, the crossbeam slides along the surfaces of the protrusions 5 on both sides of the groove 8 until it is fully engaged in the locking position.

[0033] During the locking process, the insertion rod 13 of the lock cylinder 10 is inserted into the insertion hole 12 through the guide groove 11 of the fixing seat 9 and makes contact with the lower surface of the locking beam. This securely locks the locking part 14 in the slot 8, effectively preventing loosening that may occur under vibration. The T-shaped locking part 14 and the slot 8 form a multi-directional limiting structure. Laterally, the contact between the locking beam and the side wall of the slot 8 provides limiting, while longitudinally, the insertion rod 13 and the locking beam provide limiting. When disassembly is required, simply use a special key to unlock the lock cylinder 10 and pull out the insertion rod 13, and the T-shaped locking part 14 can smoothly slide out of the slot 8.

[0034] Example 5:

[0035] In this embodiment, the fixing sleeve 1 is composed of a first assembly 2 and a second assembly 3 connected movably by a rotating shaft structure 4. Elastic rubber pads 17 are fixedly installed on the inner surfaces of both the first assembly 2 and the second assembly 3. These rubber pads 17 are made of a high-friction coefficient rubber material and are in direct contact with the outer surface of the pipe. When the fixing sleeve 1 is closed and installed on the pipe, the rubber pads 17 undergo elastic deformation under the tightening force of the bolts 6, forming a tight fit with the outer wall of the pipe. This design effectively prevents the fixing sleeve 1 from axially sliding or circumferentially rotating on the pipe surface by increasing the frictional resistance of the contact surface.

[0036] During actual installation, the operator opens the first assembly 2 and the second assembly 3 and places them on the pipe. When closed, the rubber pad 17 first contacts the pipe surface. As the locking mechanism 7 tightens, the rubber pad 17 is continuously compressed, and the elastic restoring force generated inside is converted into normal pressure on the pipe surface. According to the principle of tribology, this normal pressure and the coefficient of friction of the rubber pad 17 material together determine the anti-slip capability of the fixing sleeve 1. The pattern design on the surface of the rubber pad 17 further increases the coefficient of friction of the contact surface, ensuring that the fixing sleeve 1 remains in a stable installation state even when the pipe experiences strong vibration.

[0037] When the mounting base needs to be disassembled, the elastic deformation of the rubber pad 17 will automatically recover after the locking mechanism 7 is unlocked, making it easy to remove the first assembly 2 and the second assembly 3 from the pipe. The compressibility of the rubber pad 17 allows the same mounting base to accommodate pipes of different diameters, improving the versatility of the equipment. In addition, the rubber pad 17 also has a buffering and vibration damping effect, which can filter out high-frequency components in pipe vibration, making the signal acquired by the vibration monitoring unit 15 clearer and more reliable.

[0038] Example 6:

[0039] In this embodiment, the fixing sleeve 1 is composed of a first assembly 2 and a second assembly 3 movably connected by a rotating shaft structure 4. A protrusion 5 is provided on the first assembly 2, and a locking mechanism 7 is fixedly installed on the protrusion 5 by bolts 6. A slot 8 is provided on the protrusion 5, and the locking mechanism 7, which cooperates with it, includes a fixing seat 9 and a lock head 10 assembly. The fixing seat 9 is designed with a guide groove 11 precisely aligned with the slot 8 and an insertion hole 12, while the lock head 10 is provided with a insertion rod 13 that can be inserted into the insertion hole 12. The second assembly 3 is provided with a corresponding engaging part 14 that cooperates with the slot 8. A vibration monitoring unit 15 is fixedly installed on the inner surface of the fixing sleeve 1 for real-time acquisition of pipeline vibration data.

[0040] The key improvement in this embodiment lies in the fact that polyurethane rubber gaskets 17 are fixedly installed on the inner surfaces of both the first assembly 2 and the second assembly 3. These gaskets 17, through their unique material properties, significantly improve the connection stability between the fixing sleeve 1 and the outer wall of the pipe. Polyurethane rubber has excellent elastic deformation capacity and a high coefficient of friction. When the fixing sleeve 1 is closed and installed on the pipe, the gasket 17 undergoes appropriate compression deformation, forming a tight contact interface. This deformation not only increases the contact area but also generates continuous radial pressure, effectively preventing the fixing sleeve 1 from axially sliding and radially rotating on the pipe surface.
