Description

Technical Field

[0001] The present application relates to the technical field of fracturing pipes, and more specifically, to a high-pressure fracturing hose and an Internet of Things wear detection method for the high-pressure fracturing hose. Background Art

[0002] The fracturing fluids used in high-pressure fracturing include water-based fracturing fluids with water as the dispersion medium and oil-based fracturing fluids with mineral oil as the dispersion medium. In the high-pressure fracturing process, the fracturing fluid system carries proppant particles for fracturing. The proppant particles, carried by the high-speed injected fracturing fluid, will cause serious erosion damage to the surface of the fracturing tool. Since the pressure of the fracturing pipeline during fracturing construction ranges from tens of megapascals to hundreds of megapascals, once the fracturing pipeline is punctured, ruptured or control fails due to erosion damage, it is likely to cause serious consequences such as casualties or equipment damage. During the use of the high-pressure fracturing pipeline, the high-pressure, high-velocity, and large-flow conveying of fracturing sand will cause wear and erosion on the inner wall sealing layer of the high-pressure fracturing pipeline. In order to ensure that the high-pressure fracturing pipeline has sufficient sealing, it is necessary to regularly disassemble the high-pressure fracturing pipeline and observe the inner wall of the high-pressure fracturing pipeline with the naked eye through an endoscope, which is time-consuming and labor-intensive and affects the construction period.

[0003] Patent CN214836173U (application number: 202465945.2) provides a hose for oilfield fracturing, including a composite hose, which is composed of a wear-resistant inner rubber layer I, a wear-resistant inner rubber layer II, a steel mesh layer, an outer protective rubber layer, a thermal insulation layer and a flame retardant layer from the inside to the outside. A tracer piece I is provided inside the wear-resistant inner rubber layer I, and a tracer piece II is provided between the wear-resistant inner rubber layer I and the wear-resistant inner rubber layer II. During the use of the composite hose, a handheld radio frequency scanner is used to detect the outer surface of the composite hose, and the wear of the wear-resistant inner rubber layer I and the wear-resistant inner rubber layer II inside the composite hose can be understood through the signals fed back by the tracer pieces I and the tracer pieces II. However, the hose in patent CN214836173U needs to be detected on the outer surface of the composite hose by a handheld radio frequency scanner when in use, which makes it time-consuming and laborious to detect the wear of the internal wear-resistant inner rubber layer I and the wear-resistant inner rubber layer II of the composite hose.

[0004] In the prior art, the high-pressure, high-velocity, and large-flow conveyance of fracturing sand during the use of the high-pressure flexible fracturing manifold will cause wear and erosion to the sealing layer of the inner wall of the hose. The wear of the inner wall of the hose requires regular disassembly of the hose for visual observation using an endoscope, which is time-consuming and labor-intensive.

[0005] For example, the mortar delivery hose used in the rail transit shield industry adopts a structural design with pre-buried wires in the pipe body. The end of the pipe head is connected to a power source to monitor the conduction status of the pre-buried wires in the pipe body. If the built-in wire power supply is powered off, it means that the reverse wire has been worn off and the internal wear-resistant sealing layer has been severely damaged and needs to be replaced. In view of the on-site installation and use conditions of the high-pressure flexible fracturing manifold, which achieves random free connection, the monitoring method of the power connection wire cannot be used.

[0020] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0021] The embodiment of the present application provides a high-pressure fracturing hose, which includes a pipe body, a wear detection line and a wear detection assembly. The wear detection line is made of metal and is embedded in the pipe body along the length direction of the pipe body.

[0024] The mortar conveying hose for the rail transit shield industry proposed in the present invention adopts a structural design of pre-buried wires in the pipe body. The end of the pipe head is connected to a power supply to monitor the conduction status of the pre-buried wires in the pipe body. If the built-in wire power supply is powered off, it means that the reverse wire has been worn off and the internal wear-resistant sealing layer has been severely damaged and needs to be replaced.

[0025] In view of the on-site installation and use conditions of the high-pressure flexible fracturing manifold, a random free connection is achieved, and the monitoring method of the power connection wire cannot be used.

The wire is installed in the pipe body and the signal chip is installed at the end. The power conduction signal can be sent to the monitoring system every minute, and the wear status of the mobile phone can be monitored at the same time. At the same time, by installing a built-in large-capacity battery, the conduction signal can be continuously transmitted for more than 4 years with the operation of the hose. Automatically detect and feedback the wear of the hose to ensure the safe use of the product, while eliminating the disassembly cost and detection cost of regular detection.

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] During the use of the existing oilfield fracturing hose equipped with a tracer sheet, a handheld radio frequency scanner is required to detect the outer surface of the composite hose, and the wear condition inside the composite hose is determined by the signal fed back by the tracer sheet. This oilfield fracturing hose needs to be detected on the outer surface of the composite hose by a handheld radio frequency scanner during use, which makes the detection of the wear condition inside the composite hose time-consuming and laborious.

[0041] At the same time, in the prior art, the high-pressure, high-velocity, and large-flow conveying of fracturing sand during the use of the high-pressure flexible fracturing manifold will cause wear and erosion to the inner wall sealing layer of the hose. For the wear state of the inner wall of the hose, the hose needs to be regularly disassembled for endoscopic naked-eye observation, which is time-consuming and labor-intensive. For example, the mortar conveying hose used in the rail transit shield industry adopts a structural design of pre-buried wires in the pipe body. The end of the pipe head is connected to a power supply to monitor the conduction state of the pre-buried wires in the pipe body. If the built-in wire power supply is powered off, it means that the reverse wire has been worn off and the internal wear-resistant sealing layer has been severely damaged and needs to be replaced.

[0042] In view of the on-site installation and use conditions of the high-pressure flexible fracturing manifold, random free connection is achieved, and the monitoring method of the power connection wire cannot be used. The present invention will apply the narrow Internet of Things technology to the wear detection of the fracturing flexible hose during use. The wire is installed in the pipe body and the signal chip is installed at the end. The power conduction signal can be sent to the monitoring system every minute, and the wear status of the mobile phone can be monitored at the same time. At the same time, by installing a built-in large-capacity battery, the conduction signal can be continuously transmitted for more than 4 years with the operation of the hose. Automatically detect and feedback the wear of the hose to ensure the safe use of the product, while eliminating the disassembly cost and detection cost of regular detection.

[0043] Based on the above reasons, Figure 1-Figure 8 As shown, an embodiment of the present application provides a high-pressure fracturing hose, which includes a pipe body, a wear detection line and a wear detection assembly. The wear detection line is made of metal and is embedded in the pipe body along the length direction of the pipe body. The wear detection line and the wear detection assembly are electrically connected. The wear detection assembly is used to detect the connection state of the wear detection line. The wear detection assembly is also used to send an electrical signal indicating the wear state of the high-pressure fracturing hose according to the connection state of the wear detection line. When in use, the embodiment of the present application can automatically determine the wear state of the pipeline according to the wear detection line set in the pipe body, and send a corresponding electrical signal indicating the wear state of the pipeline according to the wear state of the pipeline. There is no need to use a handheld radio frequency scanner to detect the wear state of the pipeline, which improves the convenience of detecting the wear state of the pipeline.

[0044] In other scenarios, a high-pressure fracturing hose and an IoT wear detection method for a high-pressure fracturing hose according to an embodiment of the present application can also be applied to high-pressure flexible fracturing pipes. During use, high-pressure flexible fracturing pipes transport fracturing sand at high pressure, high flow rate, and large flow rate. The embodiments of the present application can improve the convenience of detecting the wear status of the inner wall of the high-pressure flexible fracturing pipe.

[0045] In other scenarios, a high-pressure fracturing hose and an IoT wear detection method for a high-pressure fracturing hose according to an embodiment of the present application can be applied to mortar delivery hoses in the rail transit shield industry, and can improve the convenience of detecting the wear status of the inner wall of the mortar delivery hose in the rail transit shield industry.

[0046] The following is a detailed description of a high-pressure fracturing hose and an IoT wear detection method for a high-pressure fracturing hose provided in an embodiment of the present application with reference to specific examples.

[0047] The embodiment of the present application provides a high-pressure fracturing hose, Figure 1 This is a schematic diagram of the internal structure of a high-pressure fracturing hose in an embodiment of the present application. Figure 2 for Figure 1 A schematic diagram of the structure of the AA section of a high pressure fracturing hose, Figure 3 for Figure 1 A schematic diagram of the structure of the BB section of a high pressure fracturing hose, such as Figures 1 to 3 As shown, the high-pressure fracturing hose 1 includes a tube body 11, a wear detection line 12 and a wear detection assembly 13. The wear detection line 12 is made of metal and is embedded in the tube body 11 along the length direction of the tube body 11. The wear detection line 12 and the wear detection assembly 13 are electrically connected. The wear detection assembly 13 is used to detect the connection state of the wear detection line 12. The wear detection assembly 13 is also used to send an electrical signal indicating the wear state of the high-pressure fracturing hose 1 according to the connection state of the wear detection line 12.

[0048] like Figures 1 to 3 As shown, structurally, the pipe body 11 is the main pipeline structure of the high-pressure fracturing hose 1, and the wear detection line 12 is made of metal and is embedded in the pipe body 11 along the length direction of the pipe body 11. When the pipe body 11 is worn, the wear detection line 12 will be subject to the same wear as the pipe body 11.

[0049] Exemplarily, the wear detection wire 12 can be made of metal wire (such as aluminum wire, copper wire), and the diameter of the wear detection wire 12 can be controlled between 0.02 mm and 1 mm, so that the diameter of the wear detection wire 12 is thinner, and the wear state of the wear detection wire 12 can reflect the wear state of the tube body 11.

[0050] Structurally, the wear detection line 12 and the wear detection component 13 are electrically connected. When the wear detection line 12 and the tube body 11 are worn synchronously, the power-on state of the wear detection line 12 will be affected. At this time, the connection state of the wear detection line 12 can be detected by the wear detection component 13.

[0051] When in use, after obtaining the connection state of the wear detection line 12, the wear detection component 13 can send an electrical signal indicating the wear state of the high-pressure fracturing hose 1 according to the connection state of the wear detection line 12, and then other electronic devices can receive the electrical signal indicating the wear state of the high-pressure fracturing hose 1, and then other electronic devices can receive and process the electrical signal indicating the wear state of the high-pressure fracturing hose 1, and then other electronic devices can obtain the wear state of the high-pressure fracturing hose 1.

[0052] Exemplarily, other electronic devices that receive the electrical signal indicating the wear state of the high-pressure fracturing hose 1 may be fixed communication devices with antennas, or mobile terminal devices such as mobile phones and tablet computers.

[0053] The beneficial effect brought about by the above-mentioned implementation method is that the wear state of the pipeline can be determined according to the wear detection line arranged in the pipe body, and a corresponding electrical signal indicating the wear state of the pipeline is emitted according to the wear state of the pipeline, thereby improving the convenience of detecting the wear state of the pipeline.

[0054] In some implementations, such as Figure 8 As shown, the pipe body 11 is the inner rubber layer of the high-pressure fracturing hose 1, and the wear detection line 12 is spirally embedded in the inner rubber layer of the high-pressure fracturing hose 1. By setting a wear detection line 12, which is spirally wound in the inner rubber layer, like a spring, the two ends of the wear detection line 12 are finally connected in the outer rubber layer to form a closed-loop conduction loop. If any point in the entire closed loop is disconnected, conduction cannot be formed, thereby achieving a complete real-time online monitoring purpose.

[0055] In some implementations, such as Figure 2 and Figure 3 As shown, there are multiple wear detection lines 12 which are insulated from each other. The wear detection component 13 is provided with multiple connection state detection channels for detecting the connection state of the wear detection line 12. Each wear detection line 12 is respectively connected to a connection state detection channel.

[0056] like Figure 2 and Figure 3 As shown, structurally, when the wear status of the tube body 11 is detected only by a single wear detection line 12, a failure of the single wear detection line 12 that cannot be connected may occur due to the single wear detection line 12 itself (for example, breakage during production). The embodiment of the present application sets the number of wear detection lines 12 to be multiple and insulated from each other, so that the multiple wear detection lines 12 can cooperate with each other to detect the wear status of the tube body 11, thereby avoiding the problem of poor detection effect when the wear status of the tube body 11 is detected by a single wear detection line 12.

[0057] Structurally, the wear detection component 13 is provided with a plurality of connection state detection channels for detecting the connection state of the wear detection line 12, and each wear detection line 12 is respectively connected to a connection state detection channel, so that the wear detection component 13 detects the connection state of each wear detection line 12 through a plurality of channels, thereby realizing the detection of the connectivity state of each wear detection line 12, and then the wear degree of the tube body 11 can be judged according to the number of wear detection lines 12 that are broken, and the detection result is more reliable than that when a single wear detection line 12 detects the wear state of the tube body 11.

[0058] The beneficial effect brought about by the above implementation method is that the wear degree of the pipe body is judged according to the number of wear detection lines that are broken, and the detection result is more reliable than when the wear state of the pipe body is detected by a single wear detection line.

[0059] In some implementations, the plurality of wear detection lines 12 are evenly distributed along the circumference of the pipe body 11 .

[0060] like Figure 2 and Figure 3 As shown, structurally, multiple wear detection lines 12 are evenly distributed along the circumference of the tube body 11, so that the multiple wear detection lines 12 can respectively detect the wear status of the structure of the tube body 11 in the circumference of the tube body 11, thereby realizing a comprehensive detection of the wear status of the tube body 11 in the circumference.

[0061] The beneficial effect brought about by the above implementation manner is that the multiple wear detection lines 12 realize comprehensive detection of the wear state of the tube body 11 in the circumferential direction of the tube body 11 .

[0062] In some implementations, Figure 4 Schematic diagram of the control structure of a high-pressure fracturing hose in an embodiment of the present application. Figure 4 As shown, the wear detection component 13 includes a power supply 131 and a connection detection component 132. The connection detection component 132 is provided with a plurality of connection status detection channels 133. Each wear detection line 12 is electrically connected to the power supply 131 and an connection status detection channel 133, respectively. The connection status detection channel 133 is used to detect the connection status of each wear detection line 12. The connection detection component 132 is used to send an electrical signal indicating the wear status of the high-pressure fracturing hose 1 according to the connection status of each wear detection line 12.

[0063] like Figure 4 As shown, structurally, the wear detection component 13 includes a connection detection component 132, and the connection detection component 132 is provided with a plurality of connection status detection channels 133, each connection status detection channel 133 is used to detect the wear status of a wear detection line 12, and then determine the wear status of the tube body 11 according to the wear status of the wear detection line 12.

[0064] Structurally, the wear detection component 13 also includes a power supply 131, which can supply power to the wear detection line 12 and the connection detection component 132. Each wear detection line 12 is electrically connected to the power supply 131 and an on-state detection channel 133, respectively, so that one end of each wear detection line 12 receives the current from the power supply 131.

[0065] Exemplarily, the power source 131 may be a large-capacity battery that can be installed inside the tube body 11 , and the power source 131 can drive the detection component 132 to work continuously for more than 4 years.

[0066] When in use, when the on-state detection channel 133 is able to receive an electrical signal, it can be determined that the wear detection line 12 is in the on state, indicating that the wear detection line 12 is not broken due to wear, and the corresponding position of the tube body 11 corresponding to the wear detection line 12 is not worn.

[0067] When in use, when the connection status detection channel 133 does not receive an electrical signal, it can be determined that the wear detection line 12 is in an open circuit state, indicating that the wear detection line 12 is open circuited due to wear, and the corresponding position of the tube body 11 corresponding to the wear detection line 12 has been worn and structurally missing and damaged.

[0068] When in use, the connection status detection channel 133 can detect the connection status of each wear detection line 12, so that the connection detection component 132 can obtain the wear status of multiple wear detection lines 12, and then the connection detection component 132 can send an electrical signal indicating the wear status of the high-pressure fracturing hose 1 according to the connection status of each wear detection line 12.

[0069] Exemplarily, the electrical signal indicating the wear state of the high-pressure fracturing hose 1 may be a message including the number of wear detection lines 12 that are broken, and the electrical signal indicating the wear state of the high-pressure fracturing hose 1 may also be a message indicating that the wear state of the high-pressure fracturing hose 1 is light wear, moderate wear or heavy wear, which is directly determined based on the number of wear detection lines 12 that are broken.

[0070] The beneficial effect brought about by the above-mentioned implementation method is that the wear state of the pipe body is detected by cooperating with the power supply, the connection detection component and multiple wear detection lines. The structure is simple and can cooperate with each other to realize automatic detection of the wear state of the pipe body.

[0071] In some implementations, Figure 5 FIG. 1 is a schematic diagram of a structure of a power supply and a connection detection component setting position in an embodiment of the present application, such as Figure 5 As shown in Figure a, the power supply 131 and the connection detection component 132 are respectively arranged at both ends of the tube body 11 and embedded in the tube body 11, and each wear detection line 12 extends along the length direction of the tube body 11 and is electrically connected to the power supply 131 and the connection detection component 132 respectively. Or,

[0072] like Figure 5As shown in Figure a, structurally, the power supply 131 and the connection detection component 132 are respectively arranged at both ends of the tube body 11 and embedded in the tube body 11, and each wear detection line 12 extends along the length direction of the tube body 11 and is electrically connected to the power supply 131 and the connection detection component 132 respectively, so that the power supply 131 and the connection detection component 132 are connected in a straight line structure through the wear detection line 12.

[0073] The beneficial effect brought about by the above-mentioned implementation method is that multiple wear detection lines are arranged and wired in a straight structure in the pipe body, and the power supply and connection detection components can be arranged and produced in the pipe body respectively, which reduces the production difficulty of the high-pressure fracturing hose and can improve the production efficiency of the high-pressure fracturing hose.

[0074] In some implementations, Figure 5 FIG. 1 is a schematic diagram of a structure of a power supply and a connection detection component setting position in an embodiment of the present application, such as Figure 5 As shown in Figure b, the power supply 131 and the connection detection component 132 are both arranged at the first end of the tube body 11 and embedded in the tube body 11. Each wear detection line 12 extends from the first end of the tube body 11 to the second end of the tube body 11 and then returns to extend to the first end of the tube body 11.

[0075] like Figure 5 As shown in Figure b, structurally, the power supply 131 and the connection detection component 132 are both arranged at the first end of the tube body 11 and embedded in the tube body 11, and each wear detection line 12 extends from the first end of the tube body 11 to the second end of the tube body 11 and then returns to extend to the first end of the tube body 11, so that during production, the power supply 131 and the connection detection component 132 can be directly embedded and installed in the first end of the tube body 11. When producing the tube body 11, it is only necessary to embed and install multiple wear detection lines 12 in the tube body 11 according to the pre-designed wiring structure.

[0076] Exemplarily, when each wear detection line 12 extends from the first end of the tube body 11 to the second end of the tube body 11 and then turns back to extend to the first end of the tube body 11, a spacing can be designed between the portion of each wear detection line 12 extending from the first end of the tube body 11 to the second end of the tube body 11 and the portion extending from the second end of the tube body 11 to the first end of the tube body 11. When in use, only one connection status detection channel 133 is needed to realize the wear status detection of an area that is twice the length of the tube body 11.

[0077] The beneficial effect brought about by the above implementation method is that the power supply and connection detection assembly can be designed as an integrated structure, which can simplify the production structure of the high-pressure fracturing hose and improve the production efficiency of installing the power supply and connection detection assembly into the pipe body.

[0078] The beneficial effect brought about by the above-mentioned implementation method is that, in the structure in which the power supply and the connection detection component are respectively arranged at the two ends of the pipe body, it is necessary to detect the wear status in the area corresponding to the length of the pipeline through a connection status detection channel. By arranging the power supply and the connection detection component at the same end of the pipe body, the wear status detection of the area twice the length of the pipe body can be achieved through one connection status detection channel, which can reduce the number of connection status detection channels of the connection detection component, simplify the electrical structure of the connection detection component, and reduce the production cost of the high-pressure fracturing hose.

[0079] In some implementations, Figure 6 FIG. 1 is a structural diagram of another power supply and connection detection component setting position in an embodiment of the present application, such as Figure 6 As shown, the embodiment of the present application also includes a plurality of first wear detection lines evenly distributed along the circumference of the tube body 11 and a plurality of second wear detection lines evenly distributed along the circumference of the tube body 11, the power supply 131 includes a first power supply 131a and a second power supply 131b, and the connection detection component 132 includes a first connection detection component 132a and a second connection detection component 132b.

[0080] like Figure 6 As shown, in terms of structure, in order to further improve the reliability of the wear status detection of the tube body 11 , multiple sets of power supplies 131 , multiple sets of connection detection components 132 , and multiple sets of wear detection lines 12 can be provided to detect the wear status of the tube body 11 .

[0081] Structurally, the first power supply 131a and the first connection detection component 132a are arranged at the first end of the pipe body 11 and embedded in the pipe body 11. A plurality of first wear detection lines are connected between the first power supply 131a and the first connection detection component 132a. The plurality of first wear detection lines extend from the first end of the pipe body 11 to the second end of the pipe body 11 and then return to extend to the first end of the pipe body 11. The first connection detection component 132a is used to detect the connectivity status of each first wear detection line and send an electrical signal indicating the wear status of the high-pressure fracturing hose 1 according to the connectivity status of each first wear detection line.

[0082] Structurally, the second power supply 131b and the second connection detection component 132b are arranged at the second end of the tube body 11 and embedded in the tube body 11. The second power supply 131b and the second connection detection component 132b are connected to multiple second wear detection lines. The multiple second wear detection lines extend from the second end of the tube body 11 to the first end of the tube body 11 and then return to extend to the second end of the tube body 11. The multiple second wear detection lines and the multiple first wear detection lines are insulated from each other. The second connection detection component 132b is used to detect the connectivity status of each second wear detection line, and send an electrical signal indicating the wear status of the high-pressure fracturing hose 1 according to the connectivity status of each second wear detection line.

[0083] like Figure 6 As shown, in terms of structure, the first power supply 131a and the first connection detection component 132a can cooperate with each other at the first end of the tube body 11 to detect the wear state in the tube body 11. The second power supply 131b and the second connection detection component 132b can cooperate with each other at the second end of the tube body 11 to detect the wear state in the tube body 11. This structure allows the first power supply 131a and the first connection detection component 132a to fail due to collision or other reasons at the first end of the tube body 11, while the second power supply 131b and the second connection detection component 132b at the second end of the tube body 11 may not be hit and can ensure normal operation. At this time, the wear state of the tube body 11 can still be detected by the second power supply 131b and the second connection detection component 132b, so that the first power supply 131a and the first connection detection component 132a, the second power supply 131b and the second connection detection component 132b can complement each other to achieve high-stability detection of the wear state in the tube body 11.

[0084] The beneficial effect brought about by the above-mentioned implementation method is that the first power supply 131a and the first connection detection component 132a, the second power supply 131b and the second connection detection component 132b respectively constitute two working units for detecting the wear status of the pipe body. When one group of the two working units fails, the wear status of the pipe body 11 can continue to be detected through the other group of working units, thereby achieving high-stability detection of the wear status of the pipe body 11.

[0085] In some implementations, the connection detection component 132 includes a narrow IoT connection detection component.

[0086] The beneficial effect brought about by the above-mentioned implementation method is that the characteristics of narrow band Internet of Things (NB-IoT) are low power consumption, wide coverage, low cost and high connection density. The power consumption of the connection detection component of the narrow band Internet of Things is low, which can ensure the long-term effectiveness of the connection detection component in detecting the wear status of the pipe body.

[0087] The embodiment of the present application also provides an IoT wear detection method for a high-pressure fracturing hose. The wear detection method is implemented by the high-pressure fracturing hose as described above. Figure 7 FIG. 1 is a flow chart of an IoT wear detection method for a high-pressure fracturing hose in an embodiment of the present application, such as Figure 7 As shown, the method includes S110 to S120, and S110 to S120 are described in detail below.

[0088] S110 , obtaining the connection state of the wear detection line 12 , wherein the wear detection line 12 is made of metal and is embedded in the tube body 11 along the length direction of the tube body 11 .

[0089] During use, the connection status of the wear detection line 12 can be obtained. If the wear detection line 12 is worn and cannot be conducted, it means that the wear status of the tube body 11 is seriously damaged and needs to be replaced. If the connection status of the wear detection line 12 is conducted, it means that the wear status of the tube body 11 is not seriously damaged and does not need to be replaced.

[0090] S120, when the wear detection line 12 is disconnected, an electrical signal is sent indicating that the high pressure fracturing hose 1 is excessively worn. When the wear detection line 12 is connected, an electrical signal is sent indicating that the high pressure fracturing hose 1 is not excessively worn.

[0091] When in use, if the connection state of the wear detection line 12 is disconnected, an electrical signal indicating excessive wear of the high pressure fracturing hose 1 is sent. At this time, the electrical signal indicating excessive wear of the high pressure fracturing hose 1 can be received by other electronic devices and the high pressure fracturing hose 1 can be replaced.

[0092] The beneficial effect brought about by the above implementation method is that by detecting the conduction state of the wear detection line reflecting the wear state of the pipeline and actively sending out an electrical signal indicating whether the high-pressure fracturing hose is severely worn, automatic and efficient detection of the wear detection line is achieved.

[0093] In some implementations, there are multiple wear detection lines 12 and they are insulated from each other. The above method also includes S210 to S220, and S210 to S220 are described in detail below.

[0094] S210 , detecting the connection state of each wear detection line 12 through multiple connection state detection channels of the wear detection component 13 .

[0095] When in use, since a plurality of wear detection lines 12 are provided on the tube body 11, the connection status of each wear detection line 12 can be obtained, and the wear status of the tube body 11 can be comprehensively and quantitatively judged according to the connection status of each wear detection line 12, thereby improving the detection effect of the wear status of the tube body 11.

[0096] S210: When the number of disconnected wear detection lines 12 in the connected state is greater than a preset number, an electrical signal indicating excessive wear of the high-pressure fracturing hose 1 is sent. When the number of disconnected wear detection lines 12 in the connected state is less than or equal to a preset number, an electrical signal indicating no excessive wear of the high-pressure fracturing hose 1 is sent.

[0097] During use, when the tube body 11 is produced, the wear detection line 12 in the tube body 11 may break due to twisting, molding, etc. during production. Therefore, when there are multiple wear detection lines 12, the wear state of the tube body 11 can be determined by comprehensively judging the number of broken circuits in the multiple wear detection lines 12, thereby achieving more scientific and accurate detection of the wear state of the tube body 11.

[0098] Exemplarily, the preset number may be 1 / 10 to 1 / 3 of the total number of wear detection lines 12. When the number of disconnected wear detection lines 12 in the connected state is greater than the preset number, this indicates that the wear state in the pipe body 11 is relatively serious, and the influence of breakage, disconnection and other factors caused by accidental factors and production factors during production of the wear detection lines 12 in the pipe body 11 can be ruled out. By sending an electrical signal indicating that the high-pressure fracturing hose 1 is excessively worn, accurate detection of the wear state of the pipe body 11 can be achieved.

[0099] Exemplarily, in order to ensure the reliability of the results of the wear status detection in the pipe body 11, the connection status of the wear detection line 12 in the pipe body 11 can be quality inspected when the high-pressure fracturing hose 1 leaves the factory. When the number of disconnected wear detection lines 12 in the disconnected state is greater than a preset number, the high-pressure fracturing hose 1 can be judged as having unqualified production quality, thereby avoiding inaccurate wear status detection results of the pipe body 11 in subsequent use.

[0100] The beneficial effect brought about by the above-mentioned implementation method is that it can eliminate the influence of breakage, disconnection and other factors caused by accidental factors and production factors during the production of the wear detection line in the pipe body, and realize accurate detection of the wear state of the pipe body.

[0101] In some implementations, the plurality of wear detection lines 12 are evenly distributed along the circumference of the tube body 11 , and the above method further includes S310 to S330 , which are described in detail below.

[0102] S310 , obtaining the connection status of each wear detection line 12 in the circumferential direction of the tube body 11 .

[0103] When in use, since a plurality of wear detection lines 12 are distributed circumferentially of the tube body 11 , the positions of the plurality of wear detection lines 12 in the circumferential direction can be combined with the on-off states to accurately detect the wear state and wear position on the tube body 11 .

[0104] Exemplarily, the plurality of wear detection lines 12 on the circumference of the pipe body 11 may be evenly distributed on the circumference of the pipe body 11 .

[0105] S320 , determining the number of consecutive disconnections of the wear detection lines 12 that are all disconnected and are consecutively arranged in the circumferential direction of the tube body 11 .

[0106] Structurally, multiple wear detection lines 12 evenly distributed along the circumference of the tube body 11 can be connected to multiple connection status detection channels 133 in order of position. For example, multiple wear detection lines 12 numbered 1-12 can be connected in sequence to the connection status detection channels 133 numbered 1-12 in order of position. When in use, the on-off status of each wear detection line 12 is detected by multiple connection status detection channels 133 numbered in order of position, thereby achieving the purpose of on-off detection of the combination positions of multiple wear detection lines 12.

[0107] Exemplarily, when determining the number of consecutive open circuits of the wear detection lines 12 that are all open circuits and are continuously arranged in the circumference of the tube body 11, a total of 12 wear detection lines 12, No. 1 to 12, are continuously arranged in the circumference of the tube body 11, and when it is detected that the wear detection lines 12 No. 1 to 4 are open circuits and the positions of the wear detection lines 12 No. 1 to 4 are continuously arranged in the circumference of the tube body 11, it indicates that excessive wear has occurred in the tube body 11 at the wear detection lines 12 No. 1 to 4.

[0108] In some scenarios, if part of the wear detection line 12 on the pipe body 11 is broken, but the break position of the wear detection line 12 is discontinuous, this means that the pipe body 11 has only partially suffered from excessive wear, for example, only local erosion has occurred. In this case, the pipe body 11 does not need to be replaced to save construction costs.

[0109] Exemplarily, when determining the number of consecutive open circuits of the wear detection lines 12 that are all open circuits and are continuously arranged around the circumference of the tube body 11, a total of 12 wear detection lines 12, No. 1 to 12, are continuously arranged around the circumference of the tube body 11, and it is detected that the wear detection lines No. 1 and No. 6 are open circuits, but the wear detection lines No. 1 and No. 6 are not continuously arranged around the circumference of the tube body 11, indicating that only local wear has occurred on the tube body 11 at the wear detection lines No. 1 and No. 6.

[0110] S330: When the number of continuous disconnections is greater than the preset number of continuous disconnections, a continuous wear electrical signal is issued indicating that the high pressure fracturing hose 1 is excessively worn. When the number of continuous disconnections is less than or equal to the preset number of continuous disconnections, a continuous wear electrical signal is issued indicating that the high pressure fracturing hose 1 is not excessively worn.

[0111] During use, if the number of continuous circuit breaks is greater than the preset number of continuous circuit breaks, it means that a large area of ​​wear has occurred on the pipe body 11. At this time, a continuous wear electrical signal indicating excessive wear of the high-pressure fracturing hose 1 can be issued to prompt construction personnel to replace the high-pressure fracturing hose 1.

[0112] During use, if the number of continuous disconnections is less than or equal to the preset number of continuous disconnections, a continuous wear electrical signal is sent to indicate that the high-pressure fracturing hose 1 is not excessively worn, and the high-pressure fracturing hose 1 can continue to be used.

[0113] The beneficial effect brought about by the above implementation method is that it can detect the state of local wear and large-area wear on the pipe body, and then perform more intelligent and refined detection of the high-pressure fracturing hose, which can effectively control the production cost.

[0114] In some implementations, the above method further includes S410 to S430, and S410 to S430 are described in detail below.

[0115] S410 , obtaining a connection state of each first wear detection line and a connection state of each second wear detection line.

[0116] A plurality of first wear detection lines extend from the first end of the tube body 11 to the second end of the tube body 11 and then turn back to extend to the first end of the tube body 11. A plurality of second wear detection lines extend from the first end of the tube body 11 to the second end of the tube body 11 and then turn back to extend to the first end of the tube body 11. During detection, the wear state in the tube body 11 can be detected by comprehensively judging the number of first wear detection lines whose connected state is disconnected and the number of second disconnected second wear detection lines whose connected state is disconnected.

[0117] S420: When the number of first disconnections of the first wear detection line in the disconnected state is greater than the preset first number, a first wear signal indicating excessive wear of the high pressure fracturing hose 1 is issued. When the number of second disconnections of the second wear detection line in the disconnected state is greater than the preset second number, a second wear signal indicating excessive wear of the high pressure fracturing hose 1 is issued.

[0118] During detection, when the number of first disconnections of the first wear detection line is greater than the preset first number, a first wear signal indicating excessive wear of the high-pressure fracturing hose 1 may be issued, which indicates that the high-pressure fracturing hose 1 detected by the plurality of first wear detection lines is excessively worn. At the same time, when the number of second disconnections of the disconnected second wear detection line is greater than the preset second number, a second wear signal indicating excessive wear of the high-pressure fracturing hose 1 may be issued, which indicates that the high-pressure fracturing hose 1 detected by the plurality of second wear detection lines is excessively worn.

[0119] S430: When the first wear signal and the second wear signal exist simultaneously, it is determined that the high pressure fracturing hose 1 is excessively worn.

[0120] During use, only when the first wear signal and the second wear signal are received at the same time, it means that the high-pressure fracturing hose 1 detected by the multiple first wear detection lines has excessive wear, and the high-pressure fracturing hose 1 detected by the multiple second wear detection lines has excessive wear. At this time, it can be determined that the high-pressure fracturing hose 1 has excessive wear, which can avoid false detection and detection errors caused by the first wear detection line and the second wear detection line themselves.

[0121] The beneficial effect brought about by the above implementation manner is that it can avoid false detection and also avoid detection errors caused by the first wear detection line and the second wear detection line themselves.

[0122] In some implementations, the above method further includes S510 to S530, and S510 to S530 are described in detail below.

[0123] S510, determine the first continuous open circuit number of the first wear detection lines that are all open circuited and are continuously arranged in the circumferential direction of the tube body 11 in the connection state, and determine the second continuous open circuit number of the second wear detection lines that are all open circuited and are continuously arranged in the circumferential direction of the tube body 11 in the connection state.

[0124] When in use, similar to S310 to S330, the wear state of the tube body 11 can be detected with high precision in combination with the wear states and wear positions of the continuously arranged first wear detection lines and the continuously arranged second wear detection lines.

[0125] S520: When the first continuous disconnection number is greater than the preset first continuous disconnection number, a first continuous wear electrical signal is issued indicating excessive wear of the high pressure fracturing hose 1. When the second continuous disconnection number is greater than the preset second continuous disconnection number, a second continuous wear electrical signal is issued indicating excessive wear of the high pressure fracturing hose 1.

[0126] When in use, when the first continuous circuit break number is greater than the preset first continuous circuit break number, a first continuous wear electrical signal is issued indicating that the high-pressure fracturing hose 1 is excessively worn, and at this time, it is indicated that the wear state of the pipe body 11 detected by the multiple first wear detection lines indicates that a large area of ​​the pipe body 11 has been worn. When the second continuous circuit break number is greater than the preset second continuous circuit break number, a second continuous wear electrical signal is issued indicating that the high-pressure fracturing hose 1 is excessively worn, and at this time, it is indicated that the wear state of the pipe body 11 detected by the multiple second wear detection lines indicates that a large area of ​​the pipe body 11 has been worn.

[0127] S530: When the first continuous wear signal and the second continuous wear signal exist at the same time, it is determined that the high-pressure fracturing hose 1 is excessively worn.

[0128] During use, if the external electronic device receives the first continuous wear signal and the second continuous wear signal at the same time, it means that the wear state of the pipe body 11 detected by multiple first wear detection lines has a large area of ​​wear, and the wear state of the pipe body 11 detected by multiple second wear detection lines has a large area of ​​wear. At this time, a comprehensive judgment can be made to determine that the high-pressure fracturing hose 1 has excessive wear.

[0129] The beneficial effect brought about by the above-mentioned implementation method is that in actual use, the first wear detection line and the second wear detection line may be broken due to factors such as vibration and torsion during use. At this time, by using multiple first wear detection lines to detect whether a large area of ​​the pipe body has been worn, and by using multiple second wear detection lines to detect whether a large area of ​​the pipe body has been worn, the wear state of the pipe body can be comprehensively judged, avoiding false detection caused by breaking of the first wear detection line and the second wear detection line due to factors such as vibration and torsion, thereby improving the accuracy and reliability of detection of the wear state of the pipe body.

[0130] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
