In industrial pipeline transportation systems, real-time monitoring of the internal pressure of the pipeline is crucial to ensuring the safe operation of the system.

[0003] However, existing technologies have several drawbacks: First, existing pipeline pressure monitoring devices suffer from poor adaptability, often being fixed structures designed for specific pipe diameters, requiring complete replacement of the device when changing the pipe, resulting in low versatility. Second, the sealing structure between the pressure sensor and the pipeline is rudimentary, making them prone to leakage due to vibration or media corrosion, especially in high-pressure or corrosive media environments. Third, the disassembly and assembly process is cumbersome, requiring specialized tools, hindering rapid sensor repair or replacement. Fourth, some devices lack wireless transmission capabilities, making remote monitoring difficult and unsuitable for unattended scenarios. Therefore, it is necessary to provide pipeline pressure monitoring devices to address these technical issues. Utility Model Content

[0004] This utility model provides a pipeline pressure monitoring device, which solves the following shortcomings of existing pipeline pressure monitoring devices: First, the installation structure has poor adaptability, and most are fixed structures designed for specific pipe diameters. When replacing the pipeline, the entire device needs to be replaced, resulting in low versatility. Second, the sealing structure between the pressure sensor and the pipeline is rudimentary, which is prone to leakage due to vibration or media corrosion, especially in high-pressure or corrosive media scenarios where the hidden danger is prominent. Third, the disassembly and assembly process is cumbersome, requiring professional tools, which is not conducive to quick inspection or replacement of sensors. Fourth, some devices lack wireless transmission capabilities, making it difficult to achieve remote monitoring and unsuitable for unattended scenarios.

A through hole is opened at the upper end of the pipe body. A threaded positioning tube is fixedly connected to the upper end of the second arc-shaped clamping seat. A pressure sensor is rotatably connected inside the threaded positioning tube. The lower end of the pressure sensor passes through the through hole and extends into the pipe body. A data acquisition controller is fixedly connected to the front side of the upper end of the second arc-shaped clamping seat.

[0014] This utility model provides a pipeline pressure monitoring device. Through the cooperation of the first arc-shaped clamping seat, the movable seat and the second arc-shaped clamping seat, the device adopts a "pin hinge + bolt locking" structure. The entire device can be installed by a single person in 3 minutes.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1:

[0022] Please see Figure 1-3 This utility model provides a technical solution: a pipeline pressure monitoring device, comprising: a first arc-shaped clamping seat 1, movable seats 2 fixedly connected to the rear sides of both sides of the upper end of the first arc-shaped clamping seat 1, a second arc-shaped clamping seat 3 rotatably connected to the movable seats 2, a pipeline body 4 clamped between the first arc-shaped clamping seat 1 and the second arc-shaped clamping seat 3, a through hole 5 opened at the upper end of the pipeline body 4, a threaded positioning tube 6 fixedly connected to the upper end of the second arc-shaped clamping seat 3, a pressure sensor 7 rotatably connected inside the threaded positioning tube 6, the lower end of the pressure sensor 7 passing through the through hole 5 and extending into the pipeline body 4, a data acquisition controller 8 fixedly connected to the front side of the upper end of the second arc-shaped clamping seat 3, and a buzzer 9 fixedly connected to the upper end of the data acquisition controller 8.

[0023] In this embodiment, the second arc-shaped clamping seat 3 is flipped by the movable seat 2, and the first arc-shaped clamping seat 1 is attached to the bottom of the pipe body 4. The second arc-shaped clamping seat 3 is closed so that it wraps around the upper part of the pipe body 4. After aligning the first fixing block 10 and the second fixing block 11, the first fixing block 10 and the second fixing block 11 are locked by bolts 12. The tightness is adjusted according to the diameter of the pipe body 4 (it is advisable to make the anti-slip pad slightly deformed and the device no shaking) to complete the overall mechanical fixation. Then, a small amount of sealing grease is applied to the preset through hole 5 of the pipe body 4. The sealing ring 13 at the lower end of the pressure sensor 7 is aligned with the through hole 5. The pressure sensor 7 is rotated so that it spirals down along the threaded positioning tube 6 until the detection end extends into the inside of the pipe body 4 by 10-20mm. The depth can be observed through the scale on the sensor surface. At this time, the sealing ring 13 is compressed and tightly attached to the inner wall of the through hole 5 to form a seal.

[0024] Example 2:

[0025] Please see Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution: a first fixing block 10 is fixedly connected to the upper end of the front side of the first arc-shaped clamping seat 1, and a second fixing block 11 is fixedly connected to the lower end of the front side of the second arc-shaped clamping seat 3. The first fixing block 10 and the second fixing block 11 are fixedly connected by bolts 12. The data acquisition controller 8 includes a display screen, an operation panel, and a wireless transmission module. The wireless transmission module is used for communication connection with a remote monitoring terminal. The data acquisition controller 8, the pressure sensor 7, and the buzzer 9 are electrically connected. A sealing ring 13 is sleeved on the lower end of the surface of the pressure sensor 7. The surface of the sealing ring 13 is sealed to the inner wall of the through hole 5. Anti-slip pads are provided inside the first arc-shaped clamping seat 1 and the second arc-shaped clamping seat 3. The anti-slip pads are made of nitrile rubber.

[0026] In this embodiment: During monitoring, the pressure sensor 7 collects the pressure signal inside the pipeline body 4 in real time. After being processed by the data acquisition controller 8, the value is dynamically refreshed on the display screen. When the pressure exceeds the preset threshold, the data acquisition controller 8 immediately triggers the buzzer 9 to continuously alarm. At the same time, it pushes abnormal information to the remote terminal through the wireless module. The staff can reset the alarm on-site through the operation panel or issue a reset command remotely. The system returns to normal monitoring. When the pressure sensor 7 needs to be replaced, it can be quickly removed by rotating the pressure sensor 7 in the reverse direction. After replacing the new pressure sensor 7, the above steps can be repeated. If the monitoring position needs to be adjusted, the bolt 12 is loosened and the first arc-shaped clamping seat 1 is flipped to transfer the entire device without damaging the structure of the pipeline body 4.

[0027] The working principle of the pipeline pressure monitoring device provided by this utility model is as follows:

[0028] Implementation steps for the first innovation point:

[0029] Step 1: Flip the second arc-shaped clamping seat 3 using the movable seat 2, place the first arc-shaped clamping seat 1 against the bottom of the pipe body 4, close the second arc-shaped clamping seat 3 so that it wraps around the upper part of the pipe body 4, align the first fixing block 10 and the second fixing block 11, and then lock the first fixing block 10 and the second fixing block 11 with bolts 12. Adjust the tightness according to the diameter of the pipe body 4 (it is advisable to make the anti-slip pad slightly deformed and the device no shaking) to complete the overall mechanical fixation;

[0030] Step 2: Apply a small amount of sealant to the pre-set through hole 5 of the main body of the pipe 4, align the sealing ring 13 at the lower end of the pressure sensor 7 with the through hole 5, rotate the pressure sensor 7 so that it spirals down along the threaded positioning tube 6 until the detection end extends into the inside of the main body of the pipe 4 by 10-20mm. The depth can be observed through the scale on the sensor surface. At this time, the sealing ring 13 is compressed and tightly fits the inner wall of the through hole 5 to form a seal.

[0031] Implementation steps for the second innovation point:

[0032] Step 1: During monitoring, pressure sensor 7 collects pressure signals in the main body of pipeline 4 in real time. After being processed by data acquisition controller 8, the values ​​are dynamically refreshed on the display screen. When the pressure exceeds the preset threshold, data acquisition controller 8 immediately triggers buzzer 9 to continuously alarm. At the same time, abnormal information is pushed to the remote terminal through the wireless module. Staff can reset the alarm on-site through the operation panel or issue a reset command remotely, and the system will return to normal monitoring.

[0033] Step 2: When pressure sensor 7 needs to be replaced, simply rotate pressure sensor 7 in the opposite direction to remove it quickly. After replacing the pressure sensor 7, repeat the above steps. If the monitoring position needs to be adjusted, loosen bolt 12 and flip the first arc-shaped clamping seat 1 to transfer the entire device without damaging the main structure of the pipeline 4.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
