Description

Technical Field

[0001] This utility model relates to the field of gas pipeline monitoring technology, specifically a gas pipeline network pressure monitoring device. Background Technology

[0002] Gas pipelines are a key infrastructure for the transmission of gaseous energy such as natural gas and coal gas, and are widely used. In order to ensure the safety of gas pipelines, pressure monitoring devices need to be installed on the pipelines to monitor the internal pressure.

[0003] Currently, pressure monitoring devices are pressure gauges, which are typically connected to gas pipelines via threaded connections. This means that the connection is made solely through a threaded tube and a threaded cylinder. Because the pressure gauge has only one stress point, vibrations in the pipeline during operation can cause the threaded connection of the pressure gauge to gradually loosen, leading to gas leakage. To address this, we propose a pressure monitoring device for gas pipeline networks. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a gas pipeline pressure monitoring device.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

The top of the gas pipeline is connected to a connecting component, and the bottom of the pressure gauge is connected to a connecting component, with the connecting component and the connecting component being threadedly connected. The outer surface of the pressure gauge is provided with a stabilizing mechanism, and the outer surface of the gas pipeline is provided with a positioning mechanism, with the stabilizing mechanism and the positioning mechanism fitting together. The positioning mechanism is provided with two fixing mechanisms, which are movably inserted into the stabilizing mechanism. The outer surface of the gas pipeline is provided with two mounting mechanisms, and the protective mechanism is snapped onto the two mounting mechanisms.

[0007] As a further embodiment of this utility model: the stabilizing mechanism includes two connecting rods, a positioning ring, and two slots.

[0008] As a further embodiment of this utility model: the positioning mechanism includes a connecting seat and an annular groove. The connecting seat is connected to the top of the gas pipeline and is sleeved on the outer surface of the connecting component. The annular groove is opened on the top of the connecting seat, and the outer surface of the positioning ring fits against the inner surface of the annular groove.

[0009] As a further embodiment of this utility model: the fixing mechanism includes a plug rod, a connecting plate, a handle, and a spring. The plug rod is slidably connected to the outer surface of the connecting seat, and one end of the plug rod extends into the interior of the annular groove and is movably inserted into the interior of one of the slots. The connecting plate is connected to the other end of the plug rod, the handle is connected to the front side of the connecting plate, and the spring is connected between the outer surface of the connecting seat and the back side of the connecting plate, with the spring located outside the plug rod.

[0010] As a further embodiment of this utility model: the installation mechanism includes a hollow frame, two mounting slots, a bidirectional threaded rod, two threaded blocks, two plug-in plates, and a rotating wheel. The hollow frame is connected to the outer surface of the gas pipeline. The two mounting slots are opened on both sides of the top of the hollow frame, and the interior of the hollow frame is connected to the two mounting slots. The bidirectional threaded rod is rotatably connected between the two sides of the inner wall of the hollow frame. The two threaded blocks are threadedly connected to the outer surface of the bidirectional threaded rod. The two plug-in plates are respectively connected to the opposite sides of the two threaded blocks, and the two plug-in plates are respectively located inside the two mounting slots.

[0011] As a further embodiment of this utility model: the protective mechanism includes a protective shell, a rubber pad, and four locking blocks. The protective shell is placed on top of the hollow frame and is in contact with the outer surface of the upper part of the gas pipeline. The rubber pad is connected to the top of the inner wall of the protective shell, and the outer surface of the rubber pad is in contact with the outer surface of the pressure gauge. All four locking blocks are connected to the bottom of the protective shell, and two of the locking blocks are movably inserted into the interior of two mounting slots. A transverse groove is provided on the adjacent side of two of the locking blocks and the adjacent side of the other two locking blocks. Two insertion plates are movably inserted into the two transverse grooves on two of the locking blocks.

[0012] As a further improvement of this utility model, a transparent plate is connected to the front of the protective shell.

Detailed Implementation

[0023] 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.

[0024] Example 1:

[0025] Please see Figures 1-6In this embodiment of the utility model, a gas pipeline pressure monitoring device includes: a gas pipeline 1, a pressure gauge 3, and a protective mechanism 8. The top of the gas pipeline 1 is connected to a connecting component 2, and the bottom of the pressure gauge 3 is connected to a connecting component, and the connecting component is threadedly connected to the connecting component 2. The outer surface of the pressure gauge 3 is provided with a stabilizing mechanism 4, and the outer surface of the gas pipeline 1 is provided with a positioning mechanism 5, and the stabilizing mechanism 4 is fitted with the positioning mechanism 5. The positioning mechanism 5 is provided with two fixing mechanisms 6, and the two fixing mechanisms 6 are movably inserted into the stabilizing mechanism 4. The outer surface of the gas pipeline 1 is provided with two mounting mechanisms 7, and the protective mechanism 8 is snapped onto the two mounting mechanisms 7.

[0026] Specifically, the two fixing mechanisms 6 are pulled to slide on the positioning mechanism 5. Then, the connecting component on the outer surface of the pressure gauge 3 is threaded to the connecting component 2. As the pressure gauge 3 rotates and descends, it will drive the stabilizing mechanism 4 to insert into the positioning mechanism 5. After the pressure gauge 3 is sealed and connected to the gas pipeline 1, the two fixing mechanisms 6 are released and reset and inserted into the stabilizing mechanism 4, thus locking the stabilizing mechanism 4 and improving the stability of the pressure gauge 3 after installation. The pressure gauge 3 can be protected by the protective mechanism 8. The two mounting mechanisms 7 can be moved to release the locking of the protective mechanism 8. Then, the protective mechanism 8 can be removed from the two mounting mechanisms 7 and is no longer attached to the outer surface of the gas pipeline 1. At this time, the pressure gauge 3 can be inspected. The protective mechanism 8 is placed back on the two mounting mechanisms 7 and attached to the outer surface of the gas pipeline 1. The two mounting mechanisms 7 are moved in the opposite direction to lock the protective mechanism 8 again, completing the fixed installation of the protective mechanism 8.

[0027] Example 2:

[0028] Please see Figure 4In this embodiment of the present invention, a gas pipeline pressure monitoring device includes a stabilizing mechanism 4 comprising two connecting rods 401, a positioning ring 402, and two slots 403. The two connecting rods 401 are connected to the outer surface of a pressure gauge 3. The positioning ring 402 is connected to the bottom end of the two connecting rods 401. The two slots 403 are formed on the outer surface of the positioning ring 402. The positioning mechanism 5 includes a connecting seat 501 and an annular groove 502. The connecting seat 501 is connected to the top of the gas pipeline 1 and is sleeved on the outer surface of the connecting assembly 2. The annular groove 502 is formed on the top of the connecting seat 501 and is used for positioning. The outer surface of the ring 402 fits against the inner surface of the annular groove 502. The fixing mechanism 6 includes a plug rod 601, a connecting plate 602, a handle 603, and a spring 604. The plug rod 601 is slidably connected to the outer surface of the connecting seat 501, and one end of the plug rod 601 extends into the interior of the annular groove 502 and is movably inserted into the interior of one of the slots 403. The connecting plate 602 is connected to the other end of the plug rod 601. The handle 603 is connected to the front side of the connecting plate 602. The spring 604 is connected between the outer surface of the connecting seat 501 and the back side of the connecting plate 602, and the spring 604 is located outside the plug rod 601.

[0029] Specifically, pulling the handle 603 causes the insert rod 601 to slide inside the connecting seat 501 via the connecting plate 602, causing the insert rod 601 to retract from the annular groove 502. At the same time, the spring 604 is compressed, threading the connecting component on the outer surface of the pressure gauge 3 to the connecting component 2. Simultaneously, the pressure gauge 3 rotates and descends, thereby causing the positioning ring 402 to screw into the annular groove 502 via the two connecting rods 401. This causes the bottom of the positioning ring 402 to fit against the bottom of the inner wall of the annular groove 502, thus completing the sealed connection between the pressure gauge 3 and the gas pipe 1. Then, releasing the handle 603 causes the spring 604 to reset, causing the insert rod 601 to slide in the opposite direction and insert into one of the slots 403, locking the positioning ring 402. Finally, the positioning ring 402 is fixedly installed inside the annular groove 502, providing support for the connecting component 2 and the connecting assembly.

[0030] Example 3:

[0031] Please see Figures 1-6In this embodiment of the present invention, a gas pipeline pressure monitoring device includes an installation mechanism 7 comprising a hollow frame 701, two mounting slots 702, a bidirectional threaded rod 703, two threaded blocks 704, two plug-in plates 705, and a rotating wheel 706. The hollow frame 701 is connected to the outer surface of the gas pipeline 1. The two mounting slots 702 are formed on both sides of the top of the hollow frame 701, and the interior of the hollow frame 701 is connected to the two mounting slots 702. The bidirectional threaded rod 703 is rotatably connected between the two sides of the inner wall of the hollow frame 701. The two threaded blocks 704 are threadedly connected to the outer surface of the bidirectional threaded rod 703. The two plug-in plates 705 are respectively connected to the opposite sides of the two threaded blocks 704, and the two plug-in plates 705 are respectively located inside the two mounting slots 702. The rotating wheel 706 is fixedly connected to the two mounting slots 702. On the outer surface of the threaded rod 703, the protective mechanism 8 includes a protective shell 801, a rubber pad 802, and four locking blocks 803. The protective shell 801 is placed on top of the hollow frame 701 and is in contact with the outer surface of the upper part of the gas pipe 1. The rubber pad 802 is connected to the top of the inner wall of the protective shell 801 and the outer surface of the rubber pad 802 is in contact with the outer surface of the pressure gauge 3. The four locking blocks 803 are all connected to the bottom of the protective shell 801, and two of the locking blocks 803 are movably inserted into the interior of two mounting slots 702. The adjacent side of the two locking blocks 803 and the adjacent side of the other two locking blocks 803 are provided with transverse slots. Two insertion plates 705 are respectively movably inserted into the two transverse slots on the two locking blocks 803. A transparent plate 9 is connected to the front of the protective shell 801.

[0032] Specifically, the pressure gauge 3 is shielded by the protective shell 801, and the outer surface of the rubber pad 802 can fit against the outer surface of the pressure gauge 3, thus providing rain and impact protection. Turning the rotating wheel 706 drives the bidirectional threaded rod 703 to rotate, causing the two threaded blocks 704 to move closer together and pull the two plug-in plates 705 out of the two transverse slots, releasing the locks on the two locking blocks 803. Then, the protective shell 801 can be removed from the gas pipe 1, no longer shielding the pressure gauge 3, thus facilitating maintenance and repair. Conversely, after inserting the two locking blocks 803 into the two mounting slots 702, turning the rotating wheel 706 in the opposite direction drives the two plug-in plates 705 back into the two transverse slots, thus fixing the protective shell 801 on top of the hollow frame 701, re-protecting the pressure gauge 3. The transparent plate 9 allows observation of the pressure gauge 3 inside the protective shell 801.

[0033] The working principle of this utility model is as follows: When connecting the pressure gauge 3 to the gas pipeline 1, firstly, the operator pulls the handle 603. The handle 603, through the connecting plate 602, drives the insertion rod 601 to slide inside the connecting seat 501, causing the insertion rod 601 to retract from the annular groove 502. At the same time, the spring 604 will be compressed. Then, the connecting component on the outer surface of the pressure gauge 3 is threadedly connected to the connecting component 2. As the pressure gauge 3 rotates and descends, it will drive the positioning ring 402 to screw into the annular groove 502 through the two connecting rods 401. When the bottom of the positioning ring 402 is in contact with the bottom of the inner wall of the annular groove 502, the connection between the pressure gauge 3 and the gas pipeline 1 is completed. Finally, the handle 603 is released, and the spring 604 will return to its original position, causing the insertion rod 601 to slide in the opposite direction and insert into one of the slots 403, locking the positioning ring 402. At this time, the positioning ring 402 will be stably installed inside the annular groove 502, thereby supporting the connecting component 2 and the connecting component. By shielding the pressure gauge 3 from the outside with the protective shell 801, and ensuring that the outer surface of the rubber pad 802 fits snugly against the outer surface of the pressure gauge 3, the pressure gauge 3 can be protected from rain and impact. When maintenance is required, simply place your finger on the lower part of the hollow frame 701 and continuously rotate the wheel 706. The wheel 706 will rotate the bidirectional threaded rod 703, causing the two threaded blocks 704 to move closer together on the outer surface of the bidirectional threaded rod 703. This will cause the two plug-in plates 705 to retract from the two transverse slots, releasing the locks on the two locking blocks 803. At this point, the protective shell 801 can be removed from the gas pipe 1, facilitating maintenance of the pressure gauge 3. Conversely, after inserting the two locking blocks 803 into the two mounting slots 702, rotating the wheel 706 in the opposite direction will cause the two plug-in plates 705 to re-insert into the two transverse slots, thus fixing the protective shell 801 on top of the hollow frame 701 and restoring protection to the pressure gauge 3.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
