Description

Technical Field

[0001] This invention relates to a testing device, specifically a carbon fiber pipe pressure testing device and its pressure monitoring system, belonging to the field of pressure testing technology. Background Technology

[0002] Carbon fiber tubes, also known as carbon tubes or carbon fiber tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then heating and curing them through pultrusion. They have advantages such as high strength, long life, corrosion resistance, light weight, and low density.

[0003] During the manufacturing process of carbon fiber tubes, various profiles can be produced using different molds. After the carbon fiber tubes are processed, the finished products need to be inspected for quality, and the compressive strength test is an important test in the quality inspection of carbon fiber tubes.

[0004] However, in the existing technology, the pressure resistance test of carbon fiber tubes is completed by applying pressure to the outside of the carbon fiber tube. However, when the carbon fiber tube is transporting materials, the materials flow inside the carbon fiber tube, and the impact will also occur inside the carbon fiber tube. Furthermore, when the inside of the carbon fiber tube is blocked, the internal pressure will also surge. Therefore, it is difficult to simulate the actual stress situation of the carbon fiber tube during operation by using external pressure testing method, and thus the collected carbon fiber tube pressure resistance data is not accurate enough.

[0018] This invention provides a pressure testing device and pressure monitoring system for carbon fiber pipes, which has the following beneficial effects:

[0019] 1. The carbon fiber pipe pressure testing equipment and its pressure monitoring system: The first hydraulic cylinder is controlled to perform pressure testing on the exterior of the carbon fiber pipe. Afterwards, the pressure-applying component can be controlled via the display screen to enter either the first or second state test, meeting the requirements for pressure testing of the inner wall of the carbon fiber pipe. Alternatively, the pressure-applying component can be controlled to enter the second state test first via the display screen. The expanding rubber tube applies pressure to the interior of the carbon fiber pipe while simultaneously acting as a separator. Then, the pressure-applying component is controlled to enter the second state test again via the display screen. At this time, the water pipe fills the space at the bottom of the inner cavity of the carbon fiber pipe with water, performing pressure testing on the inner wall of the carbon fiber pipe. Operators can select the required pressure testing method from the pressure testing device composed of the testing box, the first hydraulic cylinder, the support component, and the pressure-applying component, according to the needs of carbon fiber pipe production, ensuring comprehensive and accurate collection of carbon fiber pipe pressure data.

[0020] 2. The carbon fiber pipe pressure resistance testing equipment and its pressure monitoring system use a pump to draw water into the water pipe via a control valve. Since the top and bottom of the carbon fiber pipe's inner cavity are sealed with rubber components and a rubber platform, the water flowing into the pipe increases the internal water pressure. This increases the pressure on the inner wall of the carbon fiber pipe, applying force from within to conduct a pressure resistance test. Once the first pressure sensor detects that the internal water pressure has reached a certain value, the display screen electrically connected to the first pressure sensor controls the pump to stop working and the control valve to close, allowing the carbon fiber pipe to enter the static pressure resistance test phase.

[0021] 3. The carbon fiber pipe pressure resistance testing equipment and its pressure monitoring system utilize a pump to draw water into the water guide pipe via a control valve. The water, guided by a three-way valve, flows between the water guide pipe and the outer pipe. The expanding rubber tube applies pressure to the inner wall of the carbon fiber pipe, exerting pressure on multiple localized locations within the pipe. When a third pressure sensor detects that the water pressure between the water guide pipe and the outer pipe reaches a certain value, the display screen electrically connected to the third pressure sensor controls the pump to stop operating. The control valve then seals the inside of the water guide pipe, allowing for static pressure resistance testing of multiple parts within the carbon fiber pipe.

[0022] 4. The carbon fiber pipe pressure testing equipment and its pressure monitoring system: After the water pipe enters the carbon fiber pipe, a portion of the rubber component enters the carbon fiber pipe, applying force to the carbon fiber pipe with a tapered bottom and a thicker top, causing the bottom of the carbon fiber pipe to move towards the outer bottom of the rubber platform, which is tapered at the top and thickened at the bottom. Ultimately, both ends of the carbon fiber pipe are blocked by the rubber component and the rubber platform. The rubber component and the rubber platform, which have a certain elastic deformation capacity, ensure the seal at both ends of the carbon fiber pipe during the support process.

[0023] 5. The carbon fiber pipe compression testing equipment and its pressure monitoring system include an image analysis module that transmits the deformation location of the carbon fiber pipe and the time displayed on the monitor during deformation to the processor. The processor retrieves the pressure value at that location from the data storage module based on the deformation location and time. The processor captures an image of the carbon fiber pipe deformation process and transmits the image, stress location, and pressure value to the recording module. The report generation module, electrically connected to the recording module, captures multiple images from the deformation process image. The report generation module generates a report containing the images, stress location, and pressure value. Personnel can intuitively understand the external deformation of the carbon fiber pipe after localized stress based on the images and text report, and assess the quality of the carbon fiber pipe.

[0024] 6. The carbon fiber pipe pressure testing equipment and its pressure monitoring system, after the recording module receives the deformation position transmitted by the processor, the electrical connection prompt module of the recording module sends an alarm to the staff through the communication module, so that the staff stay away from the carbon fiber pipe to avoid injury, or remind the staff to stop the test, and promptly control the first hydraulic cylinder to reset or the solenoid valve and drain valve to open, so as to stop applying pressure to the carbon fiber pipe. The staff can remotely monitor the progress of the carbon fiber pipe pressure test based on the images captured by multiple cameras, and can remotely control the end of the carbon fiber pipe pressure test as needed to ensure the safety of the staff.

[0040] This invention provides a carbon fiber pipe pressure resistance testing device and its pressure monitoring system.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The test box 1 includes a test box 101, a display screen 101 and a carbon fiber tube 31. The test box 1 is fixedly connected to a first hydraulic cylinder 3, a display screen 32, a support assembly and several cameras 5. The carbon fiber tube 31 is fitted with a pressure frame 4 on the outside.

[0042] The support assembly includes a rubber platform 6, a mounting vertical pipe 7, a first pressure sensor 8, and a solenoid valve 10;

[0043] A pressurizing component is provided on the top of the support assembly. The pressurizing component includes a rubber part 16, a pump body 19, a control valve 22, a water guide pipe 23, an outer pipe 24, multiple rubber tubes 25, a three-way valve 27, a third pressure sensor 29, and a drain valve 30. The three-way valve 27 is fixedly connected inside the water guide pipe 23. A horizontal pipe 28 is provided between the three-way valve 27 and the outer pipe 24. Both the water guide pipe 23 and the outer pipe 24 are located inside the carbon fiber tube 31.

[0044] A drive assembly is provided between the pressurization component and the detection box 1. The drive assembly includes a second hydraulic cylinder 12, a moving tube 14, and a second pressure sensor 17.

[0045] The specific implementation method of this technical solution is as follows:

[0046] Example 1:

[0047] The worker places the carbon fiber tube 31 onto the top of the support assembly, so that the bottom of the inner cavity of the carbon fiber tube 31 is supported by the rubber platform 6. Then, the drive assembly is activated (details of the drive assembly's operation are below). The second hydraulic cylinder 12 operates, causing the pressurizing assembly to move downwards. This downward movement of the pressurizing assembly allows the water guide pipe 23 and the outer pipe 24 to enter the interior of the carbon fiber tube 31. Figure 1 As shown.

[0048] After the water guide pipe 23 enters the carbon fiber tube 31, a portion of the rubber component 16 also enters the carbon fiber tube 31. The rubber component 16, which is thinner at the bottom and thicker at the top, applies force to the carbon fiber tube 31, causing the bottom of the rubber platform 6, which is thinner at the bottom and thicker at the top, to move. Ultimately, both ends of the carbon fiber tube 31 are blocked by the rubber component 16 and the rubber platform 6. The rubber component 16 and the rubber platform 6, which have a certain degree of elastic deformation, support the carbon fiber tube 31, ensuring the seal at both ends of the carbon fiber tube 31.

[0049] After the carbon fiber tube 31 is sealed by the pressurizing and supporting components, the operator controls the electrically connected first hydraulic cylinder 3 via the display screen 101. The working first hydraulic cylinder 3 pushes the pressure applying frame 4 to move, and the moving pressure applying frame 4 applies force to the outside of the carbon fiber tube 31 to test the compressive strength of the carbon fiber tube 31. When the force applied to the carbon fiber tube 31 by the first hydraulic cylinder 3 through the pressure applying frame 4 reaches a predetermined value, the first hydraulic cylinder 3 is stopped, allowing the carbon fiber tube 31 to withstand a certain pressure for an extended period of time, thus performing a static pressure withstand capability test on the carbon fiber tube 31.

[0050] The staff controls the extrusion and pressurization component through the display screen 101 (details of the pressurization component operation are below) to conduct the first state test or the second state test.

[0051] Example 2:

[0052] When the staff controls the pressurization component to conduct the first state test through the display screen 101, the pump body 19 draws water and pours it into the water pipe 23 through the control valve 22. Since the top and bottom of the inner cavity of the carbon fiber tube 31 are sealed and blocked by the rubber part 16 and the rubber platform 6 respectively, the water poured into the carbon fiber tube 31 through the water pipe 23 will increase the water pressure inside the carbon fiber tube 31.

[0053] By continuously injecting water into the carbon fiber tube 31, the pressure on the inner wall of the carbon fiber tube 31 is increased, and a pressure resistance test is conducted by applying force to the carbon fiber tube 31 from the inside. After the first pressure sensor 8 detects that the water pressure inside the carbon fiber tube 31 reaches a certain value, the display screen 101, which is electrically connected to the first pressure sensor 8, controls the pump body 19 to stop working and the control valve 22 to close, so that the carbon fiber tube 31 enters the static pressure resistance test stage.

[0054] Example 3:

[0055] When the staff controls the pressurization component to conduct the second state test through the display screen 101, the display screen 101 controls the normally open end of the three-way valve 27 to close and the normally closed end to open. Then, the display screen 101 controls the pump body 19 to work. The working pump body 19 pumps water and delivers it to the water guide pipe 23 through the control valve 22. The water entering the water guide pipe 23 is guided by the three-way valve 27 to enter the space between the water guide pipe 23 and the outer pipe 24.

[0056] As the hydraulic pressure between the water guide pipe 23 and the outer pipe 24 increases, multiple rubber tubes 25 fixedly sleeved on the outside of the outer pipe 24 fill with water and expand. The expanded rubber tubes 25 apply pressure to the inner wall of the carbon fiber tube 31, applying pressure from inside the carbon fiber tube 31 to multiple local locations inside the carbon fiber tube 31. When the third pressure sensor 29 detects that the water pressure between the water guide pipe 23 and the outer pipe 24 reaches a certain value, the display screen 101 electrically connected to the third pressure sensor 29 controls the pump body 19 to stop working, and the control valve 22 operates to seal the inside of the water guide pipe 23, performing a static pressure withstand capability test on multiple parts inside the carbon fiber tube 31.

[0057] Example 4:

[0058] The operator first controls the first hydraulic cylinder 3 to perform a pressure test on the exterior of the carbon fiber tube 31. Then, depending on the testing requirements, the operator can control the pressurizing component via the display screen 101 to enter either the first or second state test, thus meeting the pressure test requirements for the inner wall of the carbon fiber tube 31. Alternatively, the operator can control the pressurizing component to enter the second state test via the display screen 101, where the expanding rubber tube 25 applies pressure to the interior of the carbon fiber tube 31 while simultaneously acting as a separator.

[0059] Subsequently, the pressurization component is controlled via display screen 101 to enter the first state test. At this time, the water guide pipe 23 fills the space at the bottom of the inner cavity of the carbon fiber tube 31 with water, and performs a pressure resistance test on the inner wall of the carbon fiber tube 31. According to the production needs of the carbon fiber tube 31, the staff selects the required pressure test method from the pressure testing device composed of the testing box 1, the first hydraulic cylinder 3, the support component, the pressurization component, etc., to ensure that the pressure resistance data of the carbon fiber tube 31 is collected comprehensively and accurately.

[0060] Please refer to it again. Figure 1 , Figure 10 and Figure 11 Several cameras 5 are fixedly connected to the inside of the detection box 1 on both sides. The first hydraulic cylinder 3 is fixedly connected between the pressure frame 4 and the detection box 1. Multiple support frames 2 are sleeved on the outside of the carbon fiber tube 31. The support frames 2 are fixedly connected to the inside of the detection box 1. The rubber platform 6 and the mounting vertical pipe 7 are both fixedly connected to the bottom of the inner cavity of the detection box 1. The first pressure sensor 8 and the solenoid valve 10 are fixedly connected to the top and bottom of the inner cavity of the mounting vertical pipe 7, respectively. The rubber platform 6 is fixedly sleeved on the outside of the mounting vertical pipe 7. Two drainage grooves 9 are opened on the outside of the first pressure sensor 8. The outlet end of the solenoid valve 10 is fixedly connected to a sewage pipe 11. One end of the sewage pipe 11 passes through the detection box 1 and is fixedly connected to the detection box 1.

[0061] Specifically, the supporting components work as follows:

[0062] After the carbon fiber tube 31 is inserted into the outside of the rubber platform 6, the first pressure sensor 8 is located at the bottom of the inner cavity of the carbon fiber tube 31, and the first pressure sensor 8 detects the water pressure inside the carbon fiber tube 31. After the control solenoid valve 10 is opened, the water inside the carbon fiber tube 31 flows to the solenoid valve 10 through the drainage groove 9 opened by the first pressure sensor 8. The water inside the carbon fiber tube 31 is finally discharged through the drain pipe 11 installed on the solenoid valve 10, thus draining the water inside the carbon fiber tube 31.

[0063] Furthermore, multiple support frames 2 are installed inside the testing chamber 1 to support the outer side of the carbon fiber tube 31, ensuring the stability of the carbon fiber tube 31 during the pressure test. Multiple cameras 5 are installed inside the testing chamber 1 to capture images of the carbon fiber tube 31 during the pressure test. The working time of the first pressure sensor 8, the third pressure sensor 29, and the first hydraulic cylinder 3 are all displayed on the monitor 32.

[0064] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The outer tube 24 is fixedly sleeved on the outside of the water guide pipe 23. The drain valve 30 is fixedly connected to the bottom of the inner cavity of the outer tube 24, and the bottom end of the drain valve 30 passes through the outer tube 24. The third pressure sensor 29 is fixedly connected to the top of the inner cavity of the outer tube 24. The rubber tube 25 is fixedly sleeved on the outside of the outer tube 24. The rubber tube 25 has multiple round holes 26 inside, which are opened on the outside of the outer tube 24. One end of the horizontal tube 28 passes through the water guide pipe 23 and is fixedly connected to the water guide pipe 23. The telescopic tube 20 is fixedly connected between the pump body 19 and the control valve 22. The mounting bracket 15 is fixedly connected inside the rubber part 16. The control valve 22 is fixedly connected inside the mounting bracket 15. The water guide pipe 23 is fixedly connected to the bottom of the control valve 22.

[0065] Specifically, the pressurization component operates as follows:

[0066] The second hydraulic cylinder 12 operates, causing the pressurizing assembly to move downwards. The rubber component 16 enters the carbon fiber tube 31, applying force to it from bottom to top. Multiple dampers 18 fixed between the moving tube 14 and the mounting bracket 15 contract under this force, transferring the force between the rubber component 16 and the carbon fiber tube 31 to the second pressure sensor 17. The second pressure sensor 17 detects the force between the carbon fiber tube 31, the rubber component 16, and the rubber platform 6. Based on the value detected by the second pressure sensor 17 displayed on the screen 101, the operator controls the drive assembly to stop operating, completing the sealing and support work for the carbon fiber tube 31.

[0067] Furthermore, a telescopic tube 20 is fixedly connected between the pump body 19 and the control valve 22, so the movement between the moving tube 14 and the mounting bracket 15 will not affect the installation and fixation of the pump body 19 and the control valve 22.

[0068] When the staff controls the pressurization component to conduct the first-state test via the display screen 101, the pump body 19 draws water through the telescopic pipe 20 and the normally open control valve 22 into the water guide pipe 23. Since the top and bottom of the inner cavity of the carbon fiber tube 31 are sealed and blocked by the rubber parts 16 and 6 respectively, the water flowing into the carbon fiber tube 31 through the water guide pipe 23 increases the water pressure inside the carbon fiber tube 31. This increases the pressure on the inner wall of the carbon fiber tube 31, thus conducting a pressure resistance test on the carbon fiber tube 31 from the inside.

[0069] The first pressure sensor 8, located at the bottom of the inner cavity of the carbon fiber tube 31, detects the water pressure inside the carbon fiber tube 31. After the value detected by the first pressure sensor 8 reaches a certain value, the display screen 101, which is electrically connected to the first pressure sensor 8, controls the pump body 19 to stop working and the control valve 22 to close, so that the carbon fiber tube 31 enters the static pressure bearing capacity test stage.

[0070] When the staff controls the pressurization component to conduct the second state test through the display screen 101, the normally open end of the electrically connected three-way valve 27 is closed and the normally closed end is opened through the display screen 101. Then the display screen 101 controls the pump body 19 to work. The working pump body 19 draws water through the telescopic pipe 20 and the control valve 22 into the water guide pipe 23. The normally closed end of the three-way valve 27 is fixedly connected to the horizontal pipe 28. Therefore, water is transported through the three-way valve 27 and the horizontal pipe 28 into the space between the water guide pipe 23 and the outer pipe 24.

[0071] As the hydraulic pressure between the water guide pipe 23 and the outer pipe 24 increases, water enters the interior of multiple rubber tubes 25 through multiple circular holes 26 in the outer pipe 24. The rubber tubes 25 expand with water, applying pressure to the inner wall of the carbon fiber tube 31, thus applying pressure to multiple localized locations within the carbon fiber tube 31. When the third pressure sensor 29 detects that the water pressure between the water guide pipe 23 and the outer pipe 24 reaches a certain value, the display screen 101, electrically connected to the third pressure sensor 29, controls the pump body 19 to stop working. The control valve 22 then seals the interior of the water guide pipe 23, performing a static pressure withstand capability test on multiple parts inside the carbon fiber tube 31.

[0072] After a period of time, the staff controlled the electrically connected drain valve 30 and solenoid valve 10 to open via the display screen 101. The water between the water pipe 23 and the outer pipe 24 flowed into the carbon fiber pipe 31 through the drain valve 30. Then, the water inside the carbon fiber pipe 31 was discharged into the sewage pipe 11 through the solenoid valve 10, thus draining the water from the carbon fiber pipe 31 and completing the pressure resistance test of the carbon fiber pipe 31.

[0073] Please refer to it again. Figure 1 Multiple dampers 18 are fixedly connected between the moving tube 14 and the mounting bracket 15. The second pressure sensor 17 is fixedly connected to the bottom of the moving tube 14. The top of the moving tube 14 passes through the detection box 1. A transmission plate 13 is fixedly connected between the top of the outer side of the moving tube 14 and the second hydraulic cylinder 12. The second hydraulic cylinder 12 is fixedly connected to one side of the detection box 1.

[0074] The driver component works as follows:

[0075] A transmission plate 13 is fixedly connected between the second hydraulic cylinder 12 and the moving pipe 14.

[0077] Specifically,

[0078] When the first hydraulic cylinder 3 is working, the pressure frame 4 applies force to the outside of the carbon fiber tube 31. When the third pressure sensor 29 is working, multiple rubber tubes 25 apply force to the inside of the carbon fiber tube 31. When the first pressure sensor 8 is working, all or the bottom of the carbon fiber tube 31 is subjected to force. Therefore, the positions of the carbon fiber tube 31 subjected to force are different when the third pressure sensor 29, the first pressure sensor 8, and the first hydraulic cylinder 3 are working.

[0079] The working time of the third pressure sensor 29, the first pressure sensor 8, and the first hydraulic cylinder 3 is displayed in real time on the display 32. Multiple cameras 5 capture the morphological changes of the carbon fiber tube 31 during the pressure test process, monitor the progress of the pressure test of the carbon fiber tube 31 in real time, and the cameras 5 can capture images of the display 32.

[0080] When the third pressure sensor 29, the first pressure sensor 8, and the first hydraulic cylinder 3 are working, the changes in their values ​​are transmitted to the carbon fiber tube 31. The display 32 transmits the changes in values ​​to the classification module 108. The classification module 108 classifies and stores the values ​​generated by the third pressure sensor 29, the first pressure sensor 8, and the first hydraulic cylinder 3 into the data storage module 109, so that the image analysis module 104 can determine the pressure value of the carbon fiber tube 31 based on the deformation position of the carbon fiber tube 31.

[0081] Images captured by multiple cameras 5 are stored in the image storage module 103. The image analysis module 104 analyzes the images transmitted from the image storage module 103. When the image analysis module 104 detects deformation in the carbon fiber tube 31, it transmits the deformation location of the carbon fiber tube 31 and the time displayed on the display 32 to the processor 105. The processor 105 then retrieves the pressure value at the deformation location from the data storage module 109 based on the deformation location and time.

[0082] The processor 105 captures images of the deformation process of the carbon fiber tube 31 and transmits the deformation process images, stress locations, and pressure values ​​to the recording module 106. The report generation module 107, which is electrically connected to the recording module 106, captures multiple images from the deformation process images and generates a report containing images, stress locations, and pressure values, such as "From top to bottom, at the first rubber tube 25 position inside the carbon fiber tube 31, after being subjected to a pressure value of N, the exterior of the carbon fiber tube 31 undergoes a slight deformation." Based on the images and text reports, staff can intuitively understand the external deformation of the carbon fiber tube 31 after localized stress and evaluate the quality of the carbon fiber tube 31.

[0083] After receiving the deformation position transmitted by the processor 105, the recording module 106, which is electrically connected to the prompting module 110, sends an alarm to the staff through the communication module 111, so that the staff can stay away from the carbon fiber tube 31 to avoid injury, or remind the staff to stop the test.

[0084] After receiving the control command from the staff, the communication module 111 transmits the control command to the instruction generation module 112. The instruction generation module 112 converts the control command into instructions to control the drain valve 30, the solenoid valve 10, and the first hydraulic cylinder 3. It promptly controls the first hydraulic cylinder 3 to reset or the solenoid valve 10 and the drain valve 30 to open, stopping the pressure applied to the carbon fiber tube 31. The staff can remotely monitor the progress of the pressure test of the carbon fiber tube 31 based on the images captured by multiple cameras 5. The staff can remotely control the end of the pressure test of the carbon fiber tube 31 as needed to ensure the safety of the staff.
