Description

Technical Field

[0001] This invention relates to the field of pipeline sealing detection technology, specifically a brine collection pipeline sealing detection device with intelligent positioning capability. Background Technology

[0002] During brine collection, leaks can occur during pipeline transportation. Traditional brine collection pipeline sealing inspections mainly rely on manual inspections and fixed-point pressure testing, which are inefficient and cannot accurately locate leak points. For long-distance, harsh environments such as surface or shallow-buried pipelines, existing technologies struggle to achieve rapid and automated leak detection and location.

[0003] Existing technology CN117570379A discloses a sealing performance testing device for natural gas pipelines. The technical solution discloses that "This invention discloses a sealing performance testing device for natural gas pipelines, specifically relating to the technical field of pipeline testing devices. It includes a movable base, with a lifting mechanism fixedly installed on the upper end of the movable base for clamping and fixing the pipeline. A testing mechanism for testing the pipeline is provided on the front side of the lifting mechanism, and a limiting mechanism for limiting the pipeline is provided on the rear side of the lifting mechanism. The sealing performance testing device for natural gas pipelines of this invention uses a sealing frame in conjunction with a movable frame to automatically seal and fix the pipe opening, effectively testing the pipeline's sealing performance. When sealing the pipe opening, three clamping plates are used to clamp the surface of the pipeline, ensuring the pipeline at the opening remains horizontal. This effectively improves the sealing effect of the sealing frame on the pipe opening, and the use of elastic springs for buffering prevents damage to the pipeline surface during clamping." Although a sealing test device for natural gas pipelines has been disclosed in the prior art, there are still some shortcomings. Specifically, the prior art mainly achieves the purpose of testing different positions of the pipeline by moving the base. However, during the movement, flanges, fasteners, etc. at the pipeline connection points can cause the test device to have a rigid collision or jam with the pipeline surface, which not only affects the continuity of the test, but may also cause wear on the device components. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent positioning brine collection pipeline sealing detection device to solve the problem of rigid collision or jamming between the detection device and the pipeline surface during the movement process in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a brine collection pipeline sealing detection device with intelligent positioning capability, comprising a detection device, the detection device comprising upper and lower mounting frames and a triggering mechanism, the inner sides of the two mounting frames being provided with a plurality of mounting plates and a plurality of detection plates, a moving mechanism being provided between two adjacent mounting plates, a detection component being provided on the detection plate, the moving mechanism being connected to the detection plate, and the detection plate being movably connected to the mounting frame; The triggering mechanism includes a trigger element, and an elastic element is disposed between the trigger element and the mounting plate. The trigger element is rotatably connected to the mounting plate and meshing with the moving mechanism. The mounting frame is a square frame, which is responsible for fitting onto the collection pipe and providing a mounting base for all detection and cleaning components. The mounting plate is the mounting support for the triggering mechanism and the moving mechanism. The triggering mechanism is used to detect the position information of flanges and bolts on the pipe and, upon contact with an obstacle, drives the detection device to move upward, avoiding rigid collisions or jamming between the detection device and obstacles on the pipe, which would affect the continuity of detection and cause wear on device components. The detection plate is equipped with multiple detection components that are in close contact with the pipe surface during operation, performing real-time detection on the pipe surface. When the trigger element contacts a flange or weld protrusion, it is lifted and rotates around the pivot, transmitting the rotational force to subsequent components. The elastic element is specifically a compression spring, which drives the trigger element to automatically reset after passing over the obstacle, preparing for the next trigger.

[0006] A locking element is also provided between two adjacent mounting plates. The locking element includes a locking chamber connected to the mounting plate. A fixing groove is formed inside the locking chamber, and an electromagnet is installed at the bottom of the fixing groove. An elastic element is mounted on the electromagnet, and a movable pin is installed at the other end of the elastic element. The locking element is used to lock the detection plate before it crosses an obstacle, preventing movement due to vibration or external interference and ensuring safety during obstacle crossing. The locking chamber serves as the mounting base for the locking element. The electromagnet controls the locking and releasing of the movable pin, attracting it when energized. The elastic element is specifically a compression spring, which stores and releases elastic potential energy, ejecting the movable pin.

[0007] The moving mechanism includes a rack slidably connected to a mounting plate and meshing with a sector gear. A second connecting rod is located at one end of the rack, and the other end of the second connecting rod is connected to a detection plate. The second connecting rod is rotatably connected to the mounting plate. A telescopic rod is provided between the mounting frame and the detection plate. A folded protrusion is provided at the lower end of the rack. The rack meshes with the sector gear, which drives the rack to move up and down. The rack drives the second connecting rod to rotate around an axis, and the second connecting rod drives the detection plate to move up and down.

[0008] The trigger element includes a connecting rod and a sector gear. The bottom end of the connecting rod has a wedge-shaped protrusion. The connecting rod is rotatably connected to the mounting plate. The sector gear meshes with a rack. The length of the trigger element's power arm is less than the length of its resistance arm. The wedge-shaped protrusion allows for better obstacle clearance, converting the horizontal collision between the connecting rod and the obstacle into a rotational lifting force that drives the sector gear. The shorter length of the trigger element's power arm allows the connecting rod to drive the detection plate upwards a greater distance even with slight vertical displacement, preventing rigid collisions or jamming between the detection device and obstacles on the pipeline.

[0009] A cleaning device is installed on the mounting frame. The cleaning device includes at least one cleaning plate, and at least one telescopic rod 2 is installed between the cleaning plate and the mounting frame. An elastic element 3 is sleeved on the telescopic rod 2. Multiple electric brush discs are installed on the cleaning plate. Specifically, the telescopic rod 2 is a hydraulically driven telescopic rod. The telescopic rod 2 cooperates with the elastic element 3 to enable the cleaning plate to automatically adapt to collection pipes of different diameters, achieving uninterrupted cleaning. The cleaning plate is used to support multiple electric brush discs, which can efficiently remove salt crystals, sludge, and other contaminants from the surface of the collection pipe, ensuring good contact between the sensor and the pipe.

[0010] The detection plate and cleaning plate are arc-shaped, and multiple sets of the detection plate and cleaning plate surround the pipe to be inspected. The shape of the detection plate and cleaning plate can match the circular outline of the pipe to ensure that there are no blind spots in cleaning and inspection.

[0011] The mounting frame is equipped with a moving device, which includes a moving element, a guide rail on the moving element, and two sliders slidably mounted on the guide rail. The moving element also has a driving element, and the two sliders are respectively connected to two mounting frames. The moving element drives the entire device to move, while the guide rail restricts the vertical movement of the two sliders. The two sliders, in turn, drive the two mounting frames to move vertically, thus facilitating the installation of the entire device onto the pipeline.

[0012] A position sensor is installed on the inner wall of the mounting frame. The detection assembly includes a temperature and humidity sensor and a vibration sensor, which are connected to the detection plate and electrically connected to the control system. The position sensor can monitor the position information of the detection plate in real time and record the specific location information of the leaking pipe. The temperature and humidity sensor is used to detect the temperature and humidity of the pipe surface. The brine leak point experiences localized low temperature and increased humidity due to evaporation. The vibration sensor is used to detect the intensity and speed of the pipe leak.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention effectively solves the problem of rigid collision or jamming between the detection device and protrusions such as flanges and fasteners on the pipe surface during the movement process by setting a triggering mechanism and a moving mechanism inside the detection device. It realizes intelligent obstacle avoidance of the detection plate. After passing the obstacle, it can drive each component back to the initial position to ensure the continuity of the detection process.

[0014] 2. The present invention uses a locking component to lock the position of the detection plate when it crosses an obstacle, without affecting the normal lifting and lowering of the detection plate, preventing the detection plate from shifting due to vibration or external interference, and improving the safety of the obstacle crossing process.

[0015] 3. The present invention can efficiently remove impurities such as salt crystals and silt from the surface of the collection pipe through a cleaning device, avoiding the impact of impurities on the detection accuracy of the sensor, significantly improving the intelligent level of brine collection pipe sealing detection, and is suitable for field pipe inspection in harsh environments.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figure 1 - Figure 6 As shown, this invention provides a technical solution: an intelligent positioning brine collection pipeline sealing detection device, comprising a detection device 2. The detection device 2 includes two mounting frames 21 and a triggering mechanism 23. Several mounting plates 22 and several detection plates 25 are arranged inside the two mounting frames 21. A moving mechanism 24 is arranged between two adjacent mounting plates 22. Detection components are arranged on the detection plates 25. The moving mechanism 24 is connected to the detection plates 25, and the detection plates 25 are movably connected to the mounting frames 21. The mounting frames 21 are square frames, responsible for fitting onto the collection pipeline, providing an installation base for all detection and cleaning components. The mounting plates 22 serve as mounting supports for the triggering mechanism 23 and the moving mechanism 24. The triggering mechanism 23 is used to detect the position information of flanges and bolts on the pipeline, and when contacting an obstacle, it drives the detection device 2 to move upward, avoiding rigid collisions or jamming between the detection device 2 and obstacles on the pipeline, which would affect the continuity of detection and cause wear on device components. Multiple detection components are arranged on the detection plates 25, which are in close contact with the pipeline surface during operation, performing real-time detection on the pipeline surface.

[0020] The triggering mechanism 23 includes a trigger element 231, and an elastic element 234 is disposed between the trigger element 231 and the mounting plate 22. The trigger element 231 is rotatably connected to the mounting plate 22 and is engaged with the moving mechanism 24. When the trigger element 231 contacts the flange or weld protrusion, it is lifted and rotates around the pivot, transmitting the rotational force to subsequent components. The elastic element 234 is specifically a compression spring, which drives the trigger element 231 to automatically reset after passing over the obstacle, preparing for the next triggering.

[0021] A locking element 242 is also provided between two adjacent mounting plates 22. The locking element 242 includes a locking chamber 2421, which is connected to the mounting plate 22. The locking chamber 2421 has a fixing groove inside, and an electromagnet 2422 is provided at the bottom of the fixing groove. An elastic element 2423 is provided on the electromagnet 2422, and a moving pin 2424 is provided at the other end of the elastic element 2423. The locking element 2422 is used to lock the detection plate 25 before it crosses the obstacle, preventing it from moving due to vibration or external interference, and ensuring the safety of the obstacle crossing process. The locking chamber 2421 is the mounting base of the locking element 242. The electromagnet 2422 is used to control the locking and releasing of the moving pin 2424. When energized, it attracts the moving pin 2424. The elastic element 2423 is specifically a compression spring, which can store elastic potential energy and release it to pop out the moving pin 2424.

[0022] The moving mechanism 24 includes a rack 241, which is slidably connected to the mounting plate 22 and meshes with a sector gear 233. A connecting rod 243 is provided at one end of the rack 241, and the other end of the connecting rod 243 is connected to the detection plate 25. The connecting rod 243 is rotatably connected to the mounting plate 22. A telescopic rod 244 is provided between the mounting frame 21 and the detection plate 25. A folded protrusion is provided at the lower end of the rack 241. The rack 241 meshes with the sector gear 233, which drives the rack 241 to move up and down. The rack 241 drives the connecting rod 243 to rotate around its axis, and the connecting rod 243 drives the detection plate 25 to move up and down.

[0023] The trigger element 231 includes a connecting rod 232 and a sector gear 233. A wedge-shaped protrusion is provided at the bottom end of the connecting rod 232. The connecting rod 232 is rotatably connected to the mounting plate 22. The sector gear 233 is meshed with the rack 241. The length of the power arm of the trigger element 231 is less than the length of the resistance arm. The wedge-shaped protrusion allows for better obstacle clearance, converting the horizontal collision between the connecting rod 232 and the obstacle into a rotational lifting force, driving the sector gear 233 to rotate. The shorter length of the power arm of the trigger element 231 compared to the resistance arm allows the connecting rod 232 to drive the detection plate 25 upwards a greater distance when experiencing a small vertical displacement, preventing the detection device 2 from rigidly colliding with or getting stuck on obstacles in the pipeline.

[0024] A cleaning device 3 is installed on the mounting frame 21. The cleaning device 3 includes at least one cleaning plate 32. At least one telescopic rod 31 is installed between the cleaning plate 32 and the mounting frame 21. An elastic element 33 is sleeved on the telescopic rod 31. Multiple electric brushes 34 are installed on the cleaning plate 32. The telescopic rod 31 is specifically a hydraulically driven telescopic rod. The telescopic rod 31 cooperates with the elastic element 33 to enable the cleaning plate 32 to automatically adapt to collection pipes of different diameters, achieving uninterrupted cleaning. The cleaning plate 32 is used to support multiple electric brushes 34. The electric brushes 34 can efficiently remove salt crystals, sludge, and other contaminants from the surface of the collection pipe, ensuring good contact between the sensor and the pipe.

[0025] The detection plate 25 and cleaning plate 32 are arc-shaped, and multiple sets of detection plates 25 and cleaning plates 32 surround the pipe to be inspected. The shape of the detection plate 25 and cleaning plate 32 can match the circular contour of the pipe to ensure that there are no blind spots in cleaning and inspection.

[0026] A moving device 1 is provided on the mounting frame 21. The moving device 1 includes a moving element 11, a guide rail 12, and two sliders 13 slidably mounted on the guide rail 12. A driving element 14 is also provided on the moving element 11. The two sliders 13 are respectively connected to the two mounting frames 21. The moving element 11 is used to drive the entire device to move, and the guide rail 12 is used to limit the vertical movement of the two sliders 13. The two sliders 13 drive the two mounting frames 21 to move vertically, thereby facilitating the installation of the entire device onto the pipeline.

[0027] A position sensor 4 is installed on the inner wall of the mounting frame 21. The detection components include a temperature and humidity sensor 5 and a vibration sensor 6. The temperature and humidity sensor 5 and the vibration sensor 6 are connected to the detection plate 25, and the position sensor 4, temperature and humidity sensor 5, and vibration sensor 6 are electrically connected to the control system. The position sensor 4 can monitor the position information of the detection plate 25 in real time and record the specific location information of the leaking pipe. The temperature and humidity sensor 5 is used to detect the temperature and humidity of the pipe surface. The brine leak point experiences localized low temperature and increased humidity due to evaporation. The vibration sensor 6 is used to detect the intensity and speed of the pipe leak.

[0028] The working principle of this invention is as follows: When in use, the moving element 11 drives the entire device to move to one side of the pipe. The position sensor 4 detects that the pipe is located between the upper and lower mounting frames 21. The control system controls the driving element 14 to operate, and the driving element 14 drives the two sliders 13 to move relative to each other along the pipe. The two sliders 13 cause the detection device 2 and the cleaning device 3 to fit tightly against the pipe surface. The driving element 14 then stops operating. Throughout the detection process, the cleaning device 3 remains in operation. Under the action of the elastic element 33, the telescopic rod 31 continuously applies pressure to the cleaning plate 32, making the cleaning plate 32 fit tightly against the pipe surface, adapting to changes in pipe diameter. Multiple electric brushes 34 on plate 2 rotate at high speed, continuously peeling off and removing salt crystals, silt, rust and other dirt from the pipe surface, providing a clean detection surface for the sensors on the subsequent detection plate 25. When the temperature and humidity sensor 5 on the detection plate 25 detects an abnormality such as a local temperature drop or humidity increase in a certain area of ​​the pipe surface due to brine evaporation, and the vibration sensor 6 detects an abnormal vibration signal in that area, the control system performs comprehensive analysis and judgment on these data. Once a seal leak is confirmed, the system immediately uses the coordinate information recorded by the position sensor 4 to accurately locate the specific location of the leak point and can issue an alarm signal to notify the operator for further processing.

[0029] Under the pull of the elastic element 234, the trigger 231 is pressed against the surface of the pipe. When the trigger 231 touches the flange, fasteners, or other protrusions on the pipe, its wedge-shaped protrusion at the bottom first contacts the obstacle, converting the horizontal collision force into an upward rotational lifting force. The trigger 231 rotates upward around the axis and compresses the elastic element 234, storing its elastic potential energy. The trigger 231 drives the sector gear 233 to rotate around the axis through the connecting rod 232. The sector gear 233 meshes with the rack 241. The drive rack 241 of the sector gear 233 moves downward along the mounting plate 22. The upper end of the rack 241 is connected to the connecting rod 243. The middle part of the connecting rod 243 is rotatably connected to the mounting plate 22. When the rack 241 moves downward, the connecting rod 243 rotates around the rotation axis in its middle part, and its other end drives the detection plate 25 to lift upward, thereby realizing the obstacle avoidance action of the detection plate 25.

[0030] When the trigger 231 starts to rotate, the sector gear 233 drives the rack 241 to move downwards. The folded protrusion at the lower end of the rack 241 first contacts and pushes the moving pin 2424 to overcome the elastic force of the second elastic element 2423 and move into the fixed groove. Then, the control system controls the electromagnet 2422 to be de-energized, the magnetic force disappears, the second elastic element 2423 releases its elastic potential energy, and the moving pin 2424 is ejected from the fixed groove and engages with the folded protrusion, locking the position of the rack 241 to prevent the detection plate 25 from moving unnecessarily due to vibration or external interference. After the detection plate 25 passes the obstacle, the control system... The system controls the electromagnet 2422 to be energized, and the electromagnet 2422 generates magnetic force to attract the moving pin 2424. The moving pin 2424 compresses the elastic element 2423 into the fixed groove, releasing the lock on the rack 241. At this time, the elastic element 234 releases the stored elastic potential energy, pushing the trigger 231 to rotate in the opposite direction around the axis to reset. The trigger 231 drives the sector gear 233 to rotate in the opposite direction through the connecting rod 232, thereby driving the rack 241 to move upward. The rack 241 drives the detection plate 25 to move downward through the connecting rod 243 until the detection plate 25 is once again attached to the surface of the pipe for detection.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
