Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring technology, specifically to an intelligent monitoring device for preventing leakage in pressure pipelines. Background Technology

[0002] In industrial sectors such as oil, natural gas, chemicals, and urban heating, pressure pipelines serve as the core carriers for transporting media (gas / liquid), and their safety directly impacts production continuity and public safety. Statistics show that pipeline connections (such as flanges and welded joints) are high-risk areas for leakage accidents, accounting for over 70%. Leaks not only lead to media waste and environmental pollution but can also trigger major safety accidents such as explosions and fires. Therefore, real-time and accurate leakage monitoring of pressure pipeline connections has become a critical requirement for industrial safety management.

[0003] Existing pressure pipelines are prone to leakage at the connection points. Because the monitoring devices for the pipelines require frequent maintenance and repair, their installation and maintenance costs are greatly increased. For some pipelines with more complex installations or lower integration, additional supports or fixing devices are required, which increases the installation complexity. Therefore, an intelligent monitoring device for preventing leakage in pressure pipelines is proposed. Utility Model Content

[0004] This utility model provides an intelligent monitoring device for preventing leakage in pressure pipelines. It is an intelligent device specifically designed to monitor in real time whether leakage occurs at the connection between two pressure pipelines. It can detect leakage at the connection in a timely, convenient and accurate manner.

[0005] This utility model is implemented as follows: a pressure pipeline anti-leakage intelligent monitoring device is installed on the lower side of the connecting pipe between two pressure pipelines, including a support base and a monitoring pipe. The monitoring pipe is threadedly connected to the support base and is sleeved on the lower side of the connecting pipe.

[0006] The monitoring tube has a semi-ring structure with opposite sides. A receiving clip is provided at the top of the monitoring tube, and a locking plate is provided at the bottom of the monitoring tube to engage with the pressure pipe. A transmission copper plate is provided on the upper side of the locking plate, and the outer surface of the monitoring tube is provided with mounting threads.

[0007] The support base is a semi-ring structure with opposing sides. The inner side wall of the support base has a threaded groove corresponding to the installation thread. The bottom of the support base has a pad that engages with the pressure pipe. The bottom of the threaded groove has a partition plate that engages with the pressure pipe. The inner side of the partition plate has a transmission copper sheet. There is a receiving chamber between the partition plate and the pad. The receiving chamber contains a monitoring module.

[0008] Preferably, the receiving housing is configured as a funnel-shaped structure.

[0009] Preferably, magnetic blocks are provided at the connection points of the two semi-ring structures of the monitoring tube.

[0010] Preferably, the two semi-ring structures of the support base are provided with connecting ears at the connection points, and the two connecting ears are fixedly connected by bolts.

[0028] Please see Figure 1-5 A pressure pipeline anti-leakage intelligent monitoring device is installed on the lower side of the connecting pipe 4 between two pressure pipelines 1, including a support base 2 and a monitoring pipe 3. The monitoring pipe 3 is threadedly connected to the support base 2 and is sleeved on the lower side of the connecting pipe 4.

[0029] The monitoring tube 3 has a semi-ring structure with opposite sides. The top of the monitoring tube 3 is provided with a receiving clip 31, and the bottom of the monitoring tube 3 is provided with a locking plate 32 that engages with the pressure pipe 1. The upper side of the locking plate 32 is provided with a transmission copper sheet 6, and the outer surface of the monitoring tube 3 is provided with an installation thread 33.

[0030] The support base 2 is a semi-ring structure with opposite sides. The inner side wall of the support base 2 is provided with a threaded groove 23 corresponding to the mounting thread 33. The bottom of the support base 2 is provided with a pad 21 that engages with the pressure pipe 1. The bottom of the threaded groove 23 is provided with a partition plate 22 that engages with the pressure pipe 1. The inner side of the partition plate 22 is provided with a transmission copper sheet 6. A receiving chamber 25 is provided between the partition plate 22 and the pad 21. A monitoring module 7 is provided in the receiving chamber 25.

[0031] This intelligent monitoring device for pressure pipeline leakage prevention is a specially designed intelligent device for real-time monitoring of whether leakage occurs at the connection between two pressure pipelines. It is cleverly positioned on the lower side of the connecting pipe between the two pressure pipelines. Through its unique structural design, it can detect leakage at the connection point promptly and accurately, and transmit the relevant information to the monitoring module for analysis and processing, providing strong protection for the safe operation of pressure pipelines.

[0032] The structure of this device is as follows:

[0033] The support base adopts a semi-ring structure design, which facilitates installation and disassembly, eliminating the need for extensive disassembly of the pressure pipeline. Simply place the two semi-ring structures in appropriate positions and connect them. Threaded grooves corresponding to the mounting threads on the outer surface of the monitoring tube are formed on the inner wall of the support base. This threaded connection not only ensures a secure connection between the monitoring tube and the support base, enabling it to withstand certain external impacts, but also facilitates disassembly and replacement when needed, improving the maintainability of the device. A pad that engages with the pressure pipeline is located at the bottom of the support base. This pad fits tightly against the outer surface of the pressure pipeline, providing stable support for the entire device and preventing shaking or displacement during use, ensuring monitoring accuracy. A partition plate that engages with the pressure pipeline is located at the bottom of the threaded groove. The partition plate serves both a separating and supporting function, isolating the monitoring tube from other components at the bottom of the support base to prevent mutual interference. The inner side of the partition plate contains transmission copper plates, which are crucial components for signal transmission, accurately transmitting the leakage signal detected by the monitoring tube to the monitoring module. A accommodating chamber is provided between the partition base plate and the support pad, which provides installation space for the monitoring module. As the core component of the entire device, the monitoring module is responsible for receiving, analyzing, and processing signals from the transmission copper plate, determining whether leakage has occurred at the pressure pipeline connection, and outputting the results in an appropriate manner, such as displaying them on a set display screen or transmitting them to an external monitoring system via a wireless communication module.

[0034] The monitoring tube also adopts a corresponding semi-ring structure, threadedly engaging with the semi-ring structure of the support base, and is located on the lower side of the connecting pipe. This design allows the monitoring tube to fully cover the key parts of the connecting pipe, ensuring comprehensive monitoring of leaks. A receiving clip is installed at the top of the monitoring tube to collect leaked gas / liquid from the connecting pipe. The collected leaked medium enters the monitoring tube. The transmission copper plate on the upper side of the bottom locking plate of the monitoring tube forms a series circuit with the transmission copper plate on the inner partition plate of the support base. When leaked medium appears inside the monitoring tube, the inner transmission copper plate generates an electrical signal based on the monitored medium. This signal is transmitted to the monitoring module via the connected transmission copper plates, thus establishing signal communication with the external monitoring system and triggering an alarm.

[0035] Working Principle: When a leak occurs in the connecting pipe between two pressure pipelines, the leaking liquid or gas first comes into contact with the transmission copper plate on the bottom locking plate of the monitoring pipe. Due to the presence of the liquid or gas, the electrical characteristics (such as resistance and capacitance) of the transmission copper plate change, generating a weak electrical signal. This signal is transmitted through the transmission copper plate to the corresponding transmission copper plate inside the support base partition plate, and then enters the monitoring module in the housing chamber. After receiving the signal, the monitoring module amplifies and filters it to improve signal quality and reliability. Next, the monitoring module analyzes the processed signal using a preset algorithm to determine whether a leak has occurred and the extent of the leak. If the monitoring module determines that a leak has occurred, it will take corresponding measures according to the pre-set program, such as issuing an alarm signal to remind personnel to handle the situation promptly; or transmitting the leak information to an external monitoring system via a wireless communication module so that managers can promptly grasp the situation and make decisions.

[0036] This intelligent monitoring device for preventing leakage in pressure pipelines, through its unique structural design and working principle, enables real-time and accurate monitoring of leakage at pressure pipeline connection points. It boasts advantages such as convenient installation, comprehensive monitoring, stable signal transmission, and intelligent analysis and processing, and has broad application prospects in the field of pressure pipeline safety monitoring.

[0037] Preferably, the receiving housing 31 is configured as a funnel-shaped structure.

[0038] The receiving casing is designed with a funnel-shaped structure, which can effectively improve the collection capacity. At the same time, the funnel-shaped structure not only helps to collect the leaked material, but also plays a guiding role, guiding it to flow downward along the inner wall of the receiving casing, thus effectively improving the collection efficiency.

[0039] Preferably, magnetic blocks 34 are provided at the connection points of the two semi-ring structures of the monitoring tube 3.

[0040] Magnetic blocks 34 are provided at the connection points of the two identical parts of the monitoring tube 3. This temporary fixing method greatly simplifies the operation steps during the installation process. The installer only needs to bring the two semi-ring structures close together, and the magnetic blocks will automatically complete the initial fixing, which greatly saves the installation time.

[0041] It should be noted that the intelligent monitoring device for preventing leakage of pressure pipelines is mainly combined and fitted at the connection of two identical pressure pipelines 1, without being connected to the internal pipeline, so as to avoid creating new leak-prone areas. Specifically, the support base 2 is set at the lower part of the outer surface of the pressure pipeline 1, the monitoring tube 3 is threaded to the inner side of the support base 2, the pressure pipelines 1 are connected by the connecting pipe 4, and the top of the monitoring tube 3 is set directly below the connecting pipe 4.

[0042] Preferably, the two semi-ring structures of the support base 2 are provided with connecting ears at the connection points, and the two connecting ears are fixedly connected by bolts 24.

[0043] The two semi-ring structure design of the support base 2 fully considers the actual needs of pressure pipeline installation. In actual operation, this design allows the support base to easily wrap around the outside of the pipeline, adapting to pipelines of different diameters and shapes. The connecting lugs provide strong support for the precise docking and stable connection of the two semi-ring structures.

[0044] During installation, the connecting lugs of the two semi-ring structures align with each other, forming a stable connection plane. Compared to some complex connection methods, the bolt connection is relatively simple to operate. Installers only need to place the two semi-ring support bases onto the pipe, align the connecting lugs, and then install the bolts and tighten the nuts in sequence. The entire process requires no special tools or complex operating skills, and even inexperienced installers can quickly get started. It features convenient installation, a tight connection, and excellent internal sealing, making it suitable for widespread application in pressure pipeline monitoring. Simply installing this device on a pressure pipeline enables convenient and efficient leak monitoring.

[0045] The bottom of the support base 2 is provided with a pad 21 that engages with the pressure pipe 1. The pad 21 has an arc-shaped groove on the side that contacts the pressure pipe to fit tightly with the pipe, reducing alignment errors during installation and shortening installation time.

[0046] Preferred, refer to Figure 2-3 The accommodating chamber 25 has an inner groove for accommodating the absorbent cotton layer 8 on its outer surface in contact with the pressure pipe 1, and the absorbent cotton layer 8 is in contact with the outer surface of the pressure pipe 1.

[0047] Since the support base 2 is composed of two semi-ring structures, its accommodating chambers 25 are two symmetrical ones. The inner grooves on opposite sides are provided with absorbent cotton layers 8. The absorbent cotton layers 8 are in contact with the outer surface of the pressure pipe 1, which facilitates the absorption of gas / liquid after monitoring.

[0048] Preferred, refer to Figure 3-4 The monitoring module 7 is in contact with the transmission copper sheet 6 on the inner side of the partition base plate 22, and the transmission copper sheet 6 on the inner side of the partition base plate 22 is signal-connected with the transmission copper sheet 6 on the upper side of the locking plate 32. The receiving housing 31 collects the leaking medium from the connecting pipe 4. The collected leaking medium enters the interior of the monitoring tube 3. The transmission copper sheet 6 on the upper side of the locking plate 32 and the transmission copper sheet 6 on the inner side of the partition base plate 22 form a series circuit. When leaking medium appears inside the monitoring tube 3, an electrical signal is generated and transmitted to the monitoring module 7. The monitoring module 7 is signal-connected to the external monitoring system and triggers an alarm.

[0049] It should be noted that the connecting plate 32 and the transmission copper sheet 6 of the partition bottom plate 22 form a series circuit. When there is leakage medium inside the monitoring tube 3, the transmission copper sheet 6 on its inner side generates an electrical signal according to the monitored medium, and then transmits the signal to the monitoring module 7 through the connected transmission copper sheet 6, thereby triggering an alarm.

[0050] Installation process:

[0051] I. Installation of Support Base

[0052] Since the support base 2 is a key basic component for connecting and fixing the entire monitoring device to the pressure pipeline 1, its installation operation is carried out first. The support base 2 consists of two identical parts. These two parts are placed at appropriate positions on the lower part of the outer surface of the pressure pipeline 1, so that the pad 21 at the bottom of the support base 2 fits into the pressure pipeline 1 through the arc-shaped groove. A partition plate 22 is provided on the bottom inner side of the support base 2. The partition plate 22 is engaged with the pressure pipeline 1 to further ensure that the support base 2 is initially and firmly fixed on the pressure pipeline 1.

[0053] After initial positioning, bolts 24 are used to pass through the mounting ears on the left and right sides of the support base 2 to fix the two identical parts of the support base 2 to each other, so that the support base 2 is firmly installed on the pressure pipeline 1, providing a stable support platform for subsequent installation of monitoring pipes and other components.

[0054] II. Installation of monitoring pipes

[0055] After the support base 2 is securely installed, the monitoring tube 3 is installed next. The monitoring tube 3 is the core component of the entire device to realize the leakage monitoring function. The monitoring tube 3 is also composed of two identical parts. At the bottom of each part, there is a locking plate 32 that is connected to the pressure pipe 1. At the top of the locking plate 32, there is a transmission copper plate 6. These transmission copper plates 6 will form a series circuit with the subsequent monitoring module to transmit the electrical signal generated by the leakage medium.

[0056] A magnetic block 34 is installed at the connection point of the two identical parts of the monitoring tube 3. During the installation process, the magnetic block 34 can provide temporary fixation, making it convenient for operators to initially connect and position the two parts.

[0057] The outer surface of the monitoring tube 3 is provided with mounting threads 33, and the inner side of the support base 2 is provided with a threaded groove 23 corresponding to the mounting threads 33. The monitoring tube 3 is tightened into the threaded groove 23 of the support base 2 through the mounting threads 33, so that the monitoring tube 3 is installed inside the support base 2, forming a sealed structure.

[0058] After the monitoring device is installed, a retaining ring 5 can be installed on the upper side of the connecting pipe 4 for added stability. Figure 1 , Figure 5As shown, although the retaining ring 5 does not directly participate in the leakage monitoring process, it plays an important role in protecting the monitoring area and improving the stability and reliability of the device. The retaining ring 5 is also composed of two identical parts. These two parts are fitted onto the upper part of the outer surface of the pressure pipe 1, located on the upper side of the connecting pipe 4. The two identical parts are fastened and fixed with screws through the fixing holes 51 opened on the outer surface of the retaining ring 5, so that the retaining ring 5 is firmly installed on the pressure pipe 1. The inner side of the retaining ring 5 is provided with a wear-resistant layer 52 that fits against the outer surface of the pressure pipe 1. The wear-resistant layer 52 can effectively reduce the friction between the retaining ring 5 and the pressure pipe 1, prevent the retaining ring 5 from sliding, and ensure that the retaining ring 5 is always in the correct position.

[0059] Connection to the outside world:

[0060] Leakage medium collection and transmission: The receiving housing 31 at the top of the monitoring tube 3 adopts a funnel-shaped design and is placed outside the connecting pipe 4 to collect the gas / liquid leaking from the connecting pipe 4. The collected leakage medium enters the interior of the monitoring tube 3. The transmission copper plate 6 on the upper side of the bottom locking plate 32 of the monitoring tube 3 and the transmission copper plate 6 on the inner partition bottom plate 22 of the support base 2 form a series circuit. When leakage medium appears inside the monitoring tube 3, the inner transmission copper plate 6 generates an electrical signal according to the monitored medium. The signal is transmitted to the monitoring module 7 through the connected transmission copper plate 6, thereby realizing the signal connection with the external monitoring system and triggering the alarm. Since the support base 2 adopts a combined tubular structure, a signal receiver can be installed nearby or directly on the support base. A power-saving Bluetooth module is then installed inside the support base 2 to extend the battery life of the device. The Bluetooth module can transmit the signal to the signal receiver and then process it through the external device. It can support quick connection and simple configuration, making it convenient for users to pair devices and transmit data.

[0061] Signal transmission of monitoring module: A monitoring module 7 is fixedly installed inside the cavity of the partition base plate 22 of the support base 2 and inside the accommodating chamber 25. The top of the monitoring module 7 is in contact with the transmission copper plate 6 located inside the partition base plate 22, receives the signal transmitted by the transmission copper plate 6, and transmits the processed signal to the external monitoring terminal to realize real-time monitoring and alarm of leakage.

[0062] Power supply installation:

[0063] Built-in battery power supply: A rechargeable battery is installed inside the monitoring module 7 to provide power to the circuit composed of the monitoring module 7 and the transmission copper plate 6. This method is suitable for some scenarios where it is inconvenient to connect to an external power source, but the battery needs to be replaced or recharged regularly.

[0064] External power connection: By setting a power interface on the support base, an external power source can be connected, and then the power can be introduced into the device through wires to power components such as the monitoring module 7. This method is suitable for scenarios with a stable external power supply and can ensure that the device works continuously and stably.
