Description

Technical Field

[0001] The present invention relates to the technical field of fluid system pipeline detection, isolation and self-reconstruction, and in particular to a pipeline damage detection and self-reconstruction system for leakage / damage detection, leakage / damage isolation and emergency self-reconstruction of liquid supply pipelines of important equipment. Background Art

[0002] Fluid system pipeline damage can be divided into three types according to the degree of damage: rupture, leakage and small leakage. Different fluid system pipelines have different tolerances to the degree of damage. For fire protection systems, once a rupture occurs (fluid loss exceeds 10% of the pipeline capacity), the pressure in the pipeline drops greatly, which may cause the fire extinguishing performance of the automatic sprinkler system to be greatly reduced and the fine water mist fire extinguishing system to lose its fire extinguishing ability. For the cooling system of some important equipment, leakage may cause the system to fail to work properly or even damage the equipment. For fuel systems, small leaks may also cause major fires within a few minutes. For chemical pipelines, small leaks may also cause personal injury and environmental damage in an instant. Therefore, how to quickly detect pipeline leaks / damages, isolate the leaks / damages as soon as possible, and resupply liquid flow to important users is a problem worth studying.

[0003] The United States first conducted research on intelligent fluid pipeline detection and fault-tolerant technology in the DC-ARM project's intelligent fire pipeline control system sub-project in 1998, and completed the program demonstration work in the same year. In March 1999, it completed the fire main structure and support evaluation of reflection technology. In January 2000, it completed the evaluation of reflection valve logic on ship fire mains. In May 2001, it completed the development of the damage control automation reflection intelligent valve prototype. Since then, through the continuous optimization of product performance, the application field of fluid pipeline detection and fault-tolerant technology has expanded from fire protection systems to cooling water systems.

[0004] At present, there are technical studies on relevant pipeline leak detection in China, such as the Chinese patent with patent number CN111399064A, which discloses a liquid leakage detection system and method. The method uses a liquid leakage detection probe and a signal sending device and a signal receiving device to realize liquid leakage detection in a confined space. A leak detection fault-tolerant control system is also disclosed in the prior art, which can detect the leakage unit and coverage of the air-conditioning refrigerant water water supply pipeline, and stop the delivery of refrigerant water to the corresponding pipeline. However, the above technical solutions can only detect the corresponding pipeline leakage, and some systems can achieve the isolation of the pipeline leakage point, but there is no technical solution that can realize pipeline self-reconstruction, and there is a lack of professional development and testing systems to provide data support for different pipeline leakage / damage flow levels. Therefore, a single detection system can only be used for a specific pipeline, and the universality and portability of the system are poor. Summary of the invention

[0005] In view of the above problems existing in the prior art, the embodiment of the present invention provides a technical solution that can detect leakage / damage of various pipeline systems, and can realize automatic alarm of pipeline rupture in fluid system, autonomous isolation of damaged areas, and self-reconstruction of emergency pipelines for important users through hierarchical logic algorithms and intelligent control technology, thereby ensuring the safe operation of important system pipelines. At the same time, it is ensured that the technical solution has good versatility and portability.

[0006] The embodiment of the present invention provides a pipeline damage detection and self-reconstruction system, including: a fluid intelligent fault-tolerant system and a development and testing system, wherein:

[0007] The fluid intelligent fault-tolerant system comprises intelligent valves respectively arranged on at least two liquid receiving flow source pipelines, a first electric butterfly valve arranged between the two connected liquid receiving flow source pipelines, and an intelligent valve logic control box for performing logic control;

[0008] The development and testing system includes a solenoid valve, an electric regulating valve, a flow meter and a second electric butterfly valve which are arranged in series on a pipeline branch between the smart valve and the user, and a smart valve development and testing box for development and testing.

[0009] In some embodiments of the present invention, the first electric butterfly valve is located between smart valves respectively arranged on two connected liquid flow source pipelines.

[0010] In some embodiments of the present invention, a check valve is further provided between the smart valves respectively provided on two connected liquid flow source pipelines.

[0011] In some embodiments of the present invention, the fluid intelligent fault-tolerant system also includes an intelligent valve system power box.

[0012] In some embodiments of the present invention, the smart valve is used to detect the pressure drop information of the pipeline where it is located, and judge the damage condition of the pipeline where the smart valve is located based on the pressure drop information, and perform corresponding isolation operations when the pipeline damage meets the set conditions.

[0013] In some embodiments of the present invention, the electric butterfly valve is used to receive control instructions from the smart valve logic control box when the pipeline where it is located needs to be reconstructed, and cooperate with the smart valve to reconstruct the pipeline based on the control instructions.

[0014] In some embodiments of the present invention, the development test system is used to define and test small leaks, leakages and damages in pipelines according to user needs, and then obtain definition data corresponding to small leaks, leakages and damages, respectively, and obtain corresponding test data, so as to provide test data for the subsequent autonomous operation of the intelligent fault-tolerant system.

[0015] In some embodiments of the present invention, the second electric butterfly valve can be fully opened instantaneously to simulate pipeline damage.

[0016] In some embodiments of the present invention, the electric regulating valve is used to adjust the opening to simulate pipeline leakage.

[0017] In some embodiments of the present invention, the flow meter is used to test the flow of pipeline damage or leakage, and provide data support for pipeline leakage or damage.

[0018] Compared with the existing patented technologies, most pipeline leakage detection systems can only detect corresponding pipeline leakage, and a small number of systems can isolate pipeline leakage points. At present, there is no technical solution that can realize pipeline self-reconstruction. At the same time, there is a lack of professional development and testing systems to provide data support for different pipeline leakage / damage flow levels. Therefore, a single detection system can only be used for a specific pipeline, and the system has poor universality and portability. The beneficial effect of the pipeline damage detection and self-reconstruction system provided by the embodiment of the present invention is that the functions of pipeline autonomous isolation and autonomous reconstruction are added on the basis of pipeline damage detection, and redundant backup operation of important users is realized. At the same time, the system is equipped with a development and testing system, which can realize the definition of different pipeline leakage / damage levels, the definition of pipeline isolation range, the definition of important pipeline users and the definition of self-reconstruction according to different application scenarios, thereby ensuring the universality and portability of the system.

[0030] The embodiment of the present invention provides a pipeline damage detection and self-reconstruction system, such as Figure 1 and Figure 2 As shown, the system includes: a fluid intelligent fault-tolerant system and a development and testing system, wherein:

[0031] The fluid intelligent fault-tolerant system comprises intelligent valves 1 respectively arranged on at least two liquid receiving flow source pipelines, a first electric butterfly valve 2 arranged between the two connected liquid receiving flow source pipelines, and an intelligent valve logic control box 9 for performing logic control;

[0032] The development and testing system includes a solenoid valve 7, an electric regulating valve 5, a flow meter 6 and a second electric butterfly valve 4 which are arranged in series in sequence on a pipeline branch between the smart valve 1 and the user, and a smart valve development test box 10 for development and testing.

[0036] Furthermore, in the above embodiment, the smart valve 1 can detect the pressure drop of the pipeline and determine the damage condition, and perform corresponding isolation operations.

[0039] In this embodiment, the second electric butterfly valve 4 can be fully opened instantaneously to simulate pipeline damage. In addition, the first electric butterfly valve 2 can also be fully opened instantaneously.

[0040] The electric regulating valve 5 is used to adjust the opening degree to simulate pipeline leakage.

[0041] The flow meter 6 is used to test the flow rate of pipeline damage or leakage, and provide data support for pipeline leakage or damage.

[0042] It can be seen from the above technical solutions that the pipeline damage detection and self-reconstruction system provided by the above embodiments of the present invention adds the functions of pipeline autonomous isolation and autonomous reconstruction on the basis of pipeline damage detection, realizes redundant backup operation of important users, and can realize automatic detection and alarm of pipeline rupture in the fluid system and autonomous isolation of the damaged area through hierarchical logic algorithm and intelligent control technology.
