Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, and in particular to a self-repairing pipeline system and method for pipelines that are easily deformed due to conveying materials. Background Art

[0002] Pipelines are important components for transporting materials. When transporting high-speed, high-pressure moving materials, pipelines are prone to various deformation problems such as expansion and local deformation due to the impact of materials. If not handled in time, it will lead to a decrease in material flow rate, a decrease in transportation efficiency, and an increase in transportation energy consumption, and may even cause serious problems such as pipeline blockage, leakage and collapse. For some pipelines in key positions for material transportation, the maintenance of the pipelines will become extremely frequent and very time-consuming and laborious. The existing pipeline maintenance is generally forced to replace new pipelines (with relatively higher maintenance efficiency), but this increases the maintenance cost, and some materials are toxic, which also brings safety hazards to maintenance personnel; some material pipelines are also pre-buried, which greatly increases the difficulty and cost of pipeline maintenance. Based on this, a pipeline system for special and complex environments is developed and innovated. The pipeline system can monitor deformation and allow deformed pipelines to self-repair, which can effectively reduce the hazards of pipeline deformation and reduce the difficulty of pipeline maintenance work, and provide adaptive technical solutions.

DETAILED DESCRIPTION

[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In one embodiment, if Figure 1-3As shown, the present invention provides a self-repairing pipeline system for conveying materials that easily causes pipeline deformation, comprising a memory pipeline substrate 1 made of a memory metal alloy material and a self-repairing device correspondingly arranged on the memory pipeline substrate 1, the self-repairing device comprising a pipeline deformation detection component, a pipeline deformation judgment model system and a self-repairing execution component, the pipeline deformation judgment model system is respectively communicated with the pipeline deformation detection component and the self-repairing execution component, the pipeline deformation detection component comprises a clamping hoop type deformation detection unit 2, the clamping hoop type deformation detection unit 2 comprises a first clamping semi-ring arm 201, a second clamping semi-ring arm 202 and an optical fiber deformation sensor A3, the first clamping semi-ring arm 201 and the second clamping semi-ring arm 202 of the clamping hoop type deformation detection unit 2 are symmetrically clamped on the outside of the memory pipeline substrate 1, an optical fiber deformation sensor A3 is connected between the top of the first clamping semi-ring arm 201 and the top of the second clamping semi-ring arm 202, and an optical fiber deformation sensor A3 is connected between the bottom of the first clamping semi-ring arm 201 and the bottom of the second clamping semi-ring arm 202 Device A3; it can be understood that the first clamping semi-ring arm 201 and the second clamping semi-ring arm 202 of the clamp-type deformation detection unit 2 are symmetrically clamped on the outside of the memory pipe matrix 1, and can accurately monitor the deformation of the memory pipe matrix 1 in real time with the optical fiber deformation sensor A3, and can obtain uniform deformation detection data within a large range of the memory pipe matrix 1. The pipeline deformation judgment model system analyzes and judges based on the received deformation detection data, quickly identifies whether the memory pipe matrix 1 has abnormal deformation, the degree and position of the deformation, and controls the self-repairing execution component to automatically repair the memory pipe matrix 1. Since the memory pipe matrix 1 is made of memory metal alloy material, it has a shape memory effect, that is, after deformation under the action of external force, it can be restored to its original shape by heating or other means; when the pipeline is deformed due to conveying materials, the system can automatically detect, judge and trigger the repair mechanism, and restore the pipeline to its original state through the self-repairing device, which greatly improves the durability and reliability of the pipeline.

[0047] The pipeline deformation judgment model system has an optical fiber deformation calculation and judgment module inside. The upper and lower optical fiber deformation sensors A3 transmit the monitored data to the optical fiber deformation calculation and judgment module. The optical fiber deformation calculation and judgment module judges the pipeline deformation according to the following method:

[0048] A1, the upper and lower optical fiber deformation sensors A detect the incident light and the emitted light of the memory pipe matrix 1 in the initial state, and obtain the initial reflected light wavelength λ of the upper and lower optical fiber deformation sensors A3 respectively. 上初 , 下初 ;

[0049] A2, the upper and lower optical fiber deformation sensors A3 record the wavelength λ of the reflected light of the memory pipe matrix 1 in real time or at intervals. 上k , 下k, k represents the serial number or time serial number of the record, and calculates the reflection wavelength difference Δλ 上 , Δλ 下 , Δλ 上 =|λ 上k -λ 上初 |,Δλ 下 =|λ 下k -λ 下初 |, if the reflected wavelength difference Δλ 上 , Δλ 下 Are greater than or equal to the set reflection wavelength difference warning value λ 预警1 , a self-repair instruction is issued to the self-repair execution component.

[0050] Understandably, the upper and lower optical fiber deformation sensors A3 can monitor the deformation detection data of the memory pipe matrix 1 and transmit it to the optical fiber deformation calculation and judgment module, wherein the deformation detection data includes the initial reflected light wavelength λ of the upper and lower optical fiber deformation sensors A3 when the memory pipe matrix 1 is in the initial state. 上初 , 下初 In real time or after an interval of time k, record the reflected light wavelength λ of the upper and lower optical fiber deformation sensors A3 at that time 上k , 下k , calculate the change in the reflected wavelength in the two states before and after, and record them as Δλ 上 , Δλ 下 ; Set the reflection wavelength difference warning value λ 预警1 , the reflection wavelength difference Δλ 上 , Δλ 下 Are greater than or equal to λ 预警1 When the memory pipe matrix 1 is damaged, the self-repairing execution component issues a self-repairing instruction to restore the memory pipe matrix 1 to its initial state; the system can monitor the deformation of the memory pipe matrix 1 in real time and issue a warning in time when deformation occurs, which helps to take measures in advance to prevent further damage to the memory pipe matrix 1. Through the self-repairing execution component, the deformation is automatically repaired without interrupting the use of the pipeline, thereby improving the reliability and service life of the memory pipe matrix 1; the optical fiber deformation sensor A3 and the precise mathematical judgment model are used for deformation judgment, which improves the accuracy and reliability of the system; the automatic repair function reduces the need for manual intervention, reduces maintenance costs and downtime.

[0051] The self-repairing execution component includes a temperature control component 5 and a plurality of temperature adjustment components distributed on the memory pipe substrate 1. The temperature control component 5 is connected to all the temperature adjustment components. The temperature control component 5 controls the operation of each temperature adjustment component and allows the memory pipe substrate 1 to reach a temperature range that causes the memory metal alloy to restore its original shape, and finally the memory pipe substrate 1 is restored to its original shape. It can be understood that the temperature control component 5 is responsible for receiving instructions from the optical fiber deformation calculation and judgment module, and accurately controlling the temperature of the memory pipe substrate 1 according to the instructions.

[0052] In one embodiment, if Figure 1 and Figure 3 As shown, the first clamping semi-ring arm 201 and the second clamping semi-ring arm 202 of the clamping hoop type deformation detection unit 2 are both provided with optical fiber deformation sensors B4 attached to the memory pipe substrate 1. The two optical fiber deformation sensors B4 on the left and right sides transmit the monitored data to the optical fiber deformation calculation and judgment module. The optical fiber deformation calculation and judgment module performs pipeline deformation judgment according to the following method:

[0053] The two optical fiber deformation sensors B1 and B4 on the left and right sides detect the incident light and the emitted light of the memory pipe matrix 1 in the initial state, and obtain the initial reflected light wavelength λ of the two optical fiber deformation sensors B4 on the left and right sides respectively. 左初 , 右初 ;

[0054] B2, two optical fiber deformation sensors B4 on the upper left and right sides record the wavelength λ of the reflected light of the memory pipe matrix 1 in real time or at intervals. 左k , 右k , k represents the serial number or time serial number of the record, and calculates the reflection wavelength difference Δλ 左 , Δλ 右 , Δλ 左 =|λ 左k -λ 左初 |,Δλ 右 =|λ 右k -λ 右初 |, if the reflected wavelength difference Δλ 左 , Δλ 右 Are greater than or equal to the set reflection wavelength difference warning value λ 预警2 , a self-repair instruction is issued to the self-repair execution component.

[0055] It can be understood that the optical fiber deformation sensor B4 is arranged on the left and right sides of the memory pipe matrix 1 (the opposite side of the optical fiber deformation sensor A3), which can be used as a parallel or parallel solution of the optical fiber deformation sensor A3, and the change in the wavelength of the reflected light between the initial state of the memory pipe matrix 1 and the state of the memory pipe matrix 1 at the interval time k is calculated, and the reflected wavelength difference warning value λ is set. 预警2 , reflection wavelength difference Δλ 左, Δλ 右 Are greater than or equal to λ 预警2 , the repair execution component issues a self-repair instruction to restore the memory pipe matrix to its initial state. By introducing the optical fiber deformation sensor B4, a redundant design for deformation monitoring of the memory pipe matrix 1 is realized. Even if one of the sensors fails or has an error, the other sensor can still work normally and provide valid data; when the two optical fiber deformation sensors work at the same time, the data provided by the two optical fiber deformation sensors can complement and verify each other, providing more comprehensive and accurate data support for repair decisions, and helping to reduce erroneous decisions caused by insufficient or inaccurate data. When the two optical fiber deformation sensors simultaneously detect that the reflection wavelength difference exceeds the warning value, the repair execution component can be triggered more quickly to issue a self-repair instruction. This timely response mechanism helps to reduce potential risks and losses caused by pipe matrix deformation.

[0056] In one embodiment, if Figure 5 As shown, both the fiber optic deformation sensor A3 and the fiber optic deformation sensor B4 use fiber Bragg grating sensors, the core of which is that a grating structure with periodic refractive index changes is formed in the fiber core through a specific process. This fine grating structure can act as a filter for light waves, selectively reflecting light waves of specific wavelengths while allowing light waves of other wavelengths to pass through, thereby achieving accurate screening and manipulation of optical signals. When the fiber Bragg grating is subjected to external deformation, such as stretching, compression or bending, the period of the grating will change slightly. This change directly affects the reflection characteristics of the grating, especially the central wavelength of the reflected light will shift, which is the so-called wavelength drift. By monitoring the wavelength change of the reflected light, the size and direction of the deformation experienced by the optical fiber can be accurately measured.

[0057] In one embodiment, if Figure 4 The memory pipe matrix 1 is made of nickel-titanium alloy, and can also be made of other metals or alloys with significant shape memory effect. Nickel-titanium alloy has two main phases: austenite phase and martensite phase. At high temperature, nickel-titanium alloy is in austenite phase, with a stable crystal structure and a high elastic modulus. When the temperature drops below a certain critical value, the nickel-titanium alloy will undergo a martensitic phase transformation and transform into a martensitic phase. At this time, the crystal structure changes, and the material becomes soft and easy to deform. This phase change is reversible, that is, when the material is heated again to above the critical temperature, the martensite phase will transform back into the austenite phase and return to its original shape. In this way, when the memory pipe matrix 1 is deformed due to the external environment or external force, it only needs a simple heating treatment to restore it to its original shape, effectively extending the service life of the memory pipe matrix 1 and reducing the maintenance cost of the pipe.

[0058] In one embodiment, if Figure 1As shown, the pipeline deformation detection assembly also includes a pressure detection unit 6, which includes a plurality of pressure sensors connected to the first clamping semi-ring arm 201 and / or the second clamping semi-ring arm 202 through a telescopic support rod 7. The pipeline deformation judgment model system also has a pressure deformation judgment module inside, and the pressure deformation judgment module performs pipeline deformation judgment according to the following method:

[0059] C1. All pressure sensors respectively record the initial pressure detection value F of the memory pipeline matrix 1 in the initial state. 初 ;

[0060] C2. All pressure sensors record the real-time pressure detection value F corresponding to the memory pipe matrix 1 in use in real time or at intervals. m , m represents the serial number or time serial number of the record, and calculates the pressure difference ΔF of each pressure sensor respectively, and sets the threshold value F of the pressure difference 预警 , if the pressure difference threshold F is exceeded 预警 If the pressure difference ΔF accounts for a proportion greater than or equal to a set proportion threshold, a self-repair instruction is issued to the self-repair execution component.

[0061] It is understandable that the pressure difference ΔF between the initial state and the state after the interval m is further recorded by the pressure sensor, and the pressure difference threshold F is set. 预警 , if the pressure difference threshold F is exceeded 预警 If the pressure difference ΔF is greater than or equal to the set percentage threshold, a self-repair instruction is issued to the self-repair execution component. The setting of the pressure sensor also realizes the redundant design of the deformation monitoring of the memory pipeline matrix 1, providing another dimension of measurement data for the repair decision, which can capture more subtle deformation changes, help to more accurately evaluate the status of the pipeline matrix 1, and can also more comprehensively trigger the repair execution component to issue a self-repair instruction, which helps to reduce the potential risks and losses caused by the deformation of the memory pipeline matrix 1.

[0062] In one embodiment, if Figure 1 As shown, the end of the telescopic support rod 7 has a flexible connection portion, and the pressure sensor is mounted on the flexible connection portion of the telescopic support rod 7. It can be understood that the telescopic support rod 7 can be extended and retracted in accordance with the deformation of the memory pipe matrix 1 to ensure the accuracy of the measurement data; the setting of the flexible connection portion can absorb and buffer the deformation or displacement of the memory pipe matrix 1, reducing the influence of the deformation on the pressure sensor.

[0063] In one embodiment, if Figure 1As shown, the memory pipe matrix 1 is made of a memory metal alloy material that can be heated and restored to its original shape; the temperature adjustment member is an electric heating device, and the temperature control component 5 controls the heating work of each temperature adjustment member and allows the memory pipe matrix 1 to reach a temperature range that causes the memory metal alloy to restore its original shape. It can be understood that the temperature control component 5 is used to monitor the temperature of the memory pipe matrix 1 in real time, and feed back the temperature information to the heating controller 8 in the temperature control component 5. The heating controller 8 controls the switch and power output of the electric heating device according to the preset temperature range and the received temperature information, thereby adjusting the heating rate and temperature of the memory pipe matrix 1.

[0064] In one embodiment, if Figure 1 As shown, the self-repairing pipeline system in which the conveying material is prone to pipeline deformation also includes a temperature compensation element, and the optical fiber deformation sensor A3 and the optical fiber deformation sensor B4 are both connected to the temperature compensation element in communication, and the temperature compensation element is used to eliminate the influence of the temperature change of the external environment on the optical fiber deformation sensor A and the optical fiber deformation sensor B4; the temperature compensation element and the optical fiber deformation sensor A3 or the optical fiber deformation sensor B4 are installed in parallel on the same optical fiber, or the temperature compensation element and the optical fiber deformation sensor A3 or the optical fiber deformation sensor B4 are installed on different optical fibers. It can be understood that the temperature compensation element can be a temperature sensitive element, such as a thermistor, a thermocouple, etc., which can directly measure the temperature and convert it into an electrical signal. By monitoring the change of the electrical signal, the measured value of the sensor can be adjusted in real time to compensate for the influence of temperature. The temperature compensation element can also be two FBG gratings, one of which is used as a sensing element to detect deformation, and the other is used as a temperature compensation element that is only sensitive to temperature changes. By comparing the reflection wavelength changes of the two gratings, the wavelength change caused by deformation and the wavelength change caused by temperature changes can be separated, thereby achieving compensation for the temperature effect.

[0065] In one embodiment, if Figure 1 As shown, the first clamping half ring arm 201 and the second clamping half ring arm 202 are both made of elastic, non-flammable and explosive materials. It is understandable that when the memory pipe base 1 is deformed due to temperature changes, pressure fluctuations, etc., the first clamping half ring arm 201 and the second clamping half ring arm 202 can be deformed accordingly, and will not cause clamping failure or damage due to excessive rigidity.

[0066] In one embodiment, if Figure 1As shown, the pipeline deformation judgment model system also includes a controller 8 built into the pipeline deformation judgment model system, the optical fiber deformation sensor A, the optical fiber deformation sensor B4 and the pressure sensor are connected to the controller 8, and the controller 8 is connected to the temperature adjustment member. It can be understood that the controller 8, as a data processing center, can receive and process data from various sensors, conduct comprehensive analysis through preset algorithms and models, accurately determine whether the memory pipeline matrix 1 is deformed, the degree and position of the deformation, and control the heating work of each temperature adjustment member to allow the memory pipeline matrix 1 to reach a temperature range that causes the memory metal alloy to restore its original shape.

[0067] The present invention also provides a self-repairing method for a key pre-buried pipeline that is easily deformed and damaged when conveying materials, comprising the following steps:

[0068] The pipeline deformation judgment model system has an optical fiber deformation calculation and judgment module inside. The upper and lower optical fiber deformation sensors A transmit the monitored data to the optical fiber deformation calculation and judgment module.
