Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to an inspection device for thermal production pipelines. Background Technology

[0002] Thermal production pipelines are primarily used to transport heat energy media such as steam and hot water, connecting heat sources to user terminals. Their core purpose is to achieve efficient heat energy transmission and distribution, meeting the heating and power needs of industrial production, as well as the heating and hot water supply for residential buildings. Pipeline transportation reduces heat loss, ensures a stable heat source supply, and replaces decentralized heating, reducing energy waste and pollutant emissions. It is both economical and environmentally friendly, making it a key infrastructure for centralized heating and industrial thermal energy systems.

[0003] Thermal power production pipeline inspection devices collect pipeline data through sensors, which are then analyzed by a processor to determine defects. For example, ultrasonic detectors use sound wave reflection to identify wall thinning and cracks; infrared imagers capture temperature anomalies and locate leaks. These devices can be widely used for quality inspection during the acceptance of new pipelines; regular inspections of operating pipelines to monitor corrosion and wear; safety assessments of aging pipelines to prevent pipe bursts; and rapid location of leaks or blockages during emergency repairs, ensuring the safe and efficient operation of thermal systems and reducing downtime losses.

[0004] In existing technologies, some pipeline inspection devices are typically designed as integrated units, making it difficult to disassemble them in a timely manner when they are damaged. This makes it difficult to separate them directly during maintenance, and forced removal can damage components, thus increasing disassembly time, extending maintenance cycles, and causing long-term interruptions in inspection of thermal production pipelines due to device maintenance, increasing downtime losses. Therefore, a new inspection device for thermal production pipelines is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a testing device for a thermal production pipeline, comprising a protective shell 2. The protective shell 2 protects internal components such as the testing machine 1 and provides sliding space for components such as the square slider 7. Multiple sliding rods 3 are slidably connected inside the protective shell 2. The sliding of the sliding rods 3 can drive the base plate 5 and the sliding block 6 to move, providing a motion basis for disassembling the testing machine 1 from the protective shell 2. The base plate 5 is fixedly connected to the adjacent side of the multiple sliding rods 3. The base plate 5 connects the sliding rods 3 and the sliding block 6 and can transmit the force of the sliding rods 3 to the sliding block 6. The base plate 5 is also connected to a spring 4, which can be reset after disassembly for reinstallation. The spring 4 is fixedly connected to the distant side of the multiple base plates 5. The spring 4 connects the base plate 5 and the limiting block 10. When the sliding block 6 drives the base plate 5 to move, the spring 4 deforms and stores elastic force. After disassembly, the elastic force can be released to drive the components to reset.

[0034] Multiple base plates 5 are fixedly connected to adjacent sides with sliding blocks 6. The sliding blocks 6 connect the base plates 5 and the protruding blocks 8. Their sliding will drive the top triangular blocks to move. When the triangular blocks are dislodged from the slots 9, the protruding blocks 8 lose their limit and are easy to disassemble with the inspection machine 1. Two protruding blocks 8 are slidably connected to adjacent sides of the multiple sliding blocks 6. The top of the protruding blocks 8 is connected to the inspection machine 1, and its exterior is slidably connected to the protective shell 2. When the triangular blocks are inserted into the slots 9, the protruding blocks 8 are limited to fix the inspection machine 1. When they are dislodged, they can slide to achieve disassembly. The top of the two protruding blocks 8 is fixedly connected to the inspection machine 1. The inspection machine 1 can be controlled by the control panel to move the mover 13, receive data from the sensor 12 and display the pipeline status. It is the core of control and data reception. Multiple limit blocks 10 are fixedly connected inside the protective shell 2. The limit blocks 10 are fixed inside the protective shell 2 to fix one end of the spring 4 and limit the range of movement of the components to prevent excessive sliding and damage to the structure.

[0035] The left side of the testing machine 1 is fixedly connected to a fixing component for testing. The fixing component can fix different sensors 12 to ensure stable data acquisition and transmission, expand the corresponding detection target range and ensure data accuracy. The external of multiple limit blocks 10 is fixedly connected to the inside of the protective shell 2. The limit blocks 10 and the protective shell 2 are fixed to provide a fulcrum for the spring 4, enhance the structural stability, and make the force of the spring 4 stable when it extends and retracts. The far sides of multiple springs 4 are fixedly connected to the near sides of multiple limit blocks 10. The two ends of the spring 4 are respectively connected to the base plate 5 and the limit block 10. After deformation, it can drive the base plate 5 to reset, so that the triangular block can be re-engaged into the slot 9 to re-fix the testing machine 1. The external of multiple sliding blocks 6 is fixedly connected to two square sliders 7. The square sliders 7 are fixed to the outside of the sliding blocks 6. Sliding them can drive the sliding blocks 6 to slide. They are the direct parts for the operator to operate and disassemble.

[0036] Multiple square sliders 7 are externally slidably connected to the inside of the protective shell 2. The square sliders 7 slide inside the protective shell 2 to guide the movement of the sliding block 6, ensuring that the triangular block accurately disengages or engages with the slot 9, so that disassembly and fixing can be carried out smoothly. The two protruding blocks 8 have slots 9 inside, which cooperate with the top triangular block of the sliding block 6. When engaged, the protruding block 8 is limited and fixed to the testing machine 1. When disengaged, the limitation is released to facilitate disassembly. The two protruding blocks 8 are externally slidably connected to the inside of the protective shell 2. The protruding blocks 8 slide inside the protective shell 2 to allow the testing machine 1 to move relative to each other. It can be easily removed during disassembly and can be slid in and fixed by the triangular block and the slot 9 during installation.

[0037] Reference Figure 4 , Figure 5 The fixed component includes a connecting cable 11, which connects the detector 1 and the sensor 12 to realize signal and data transmission, enabling the sensor 12 to transmit data to the detector 1. The detector 1 can also control the mover 13 through it. The right side of the connecting cable 11 is fixedly connected to the left side of the detector 1. The connection between the connecting cable 11 and the detector 1 is fixed to ensure a stable connection and prevent data transmission interruption, ensuring that the detector 1 can stably receive data and send commands. The other end of the connecting cable 11 is equipped with the sensor 12, which is connected to the detector 1 through the connecting cable 11. The sensor 12 can collect information such as pipe temperature, pressure, wall thinning, and cracks, and transmit the data to the detector 1. The bottom of the sensor 12 is equipped with a mover 13, which provides a platform for the sensor 12 and can move it along the pipe to expand the detection range. Its movement is controlled by the detector 1 through the connecting cable 11 to ensure comprehensive detection.

[0038] The mover 13 is internally connected to an electric push rod 14, which is a driving component. Its extension and retraction drive the sliding ring 15 to slide along the fixed rod 16, thereby causing the clamping block 20 to clamp or release the sensor 12 through transmission. This adapts to sensors 12 of different sizes, improving installation efficiency. The driving end of the electric push rod 14 is fixedly connected to the sliding ring 15. The sliding ring 15 connects the electric push rod 14 and the connecting rod 17, converting the linear motion of the electric push rod 14 into the rotation of the connecting rod 17. It is a key component of the transmission, and its sliding directly drives the movement of subsequent components. The sliding ring 15 is internally connected to the fixed rod 16, which guides the sliding ring 15 to ensure that it moves in a straight line, stabilizing the rotation angle of the connecting rod 17 and ensuring that the clamping block 20 accurately clamps the sensor 12. The external part of the sliding ring 15 is rotatably connected to two connecting rods 17, which connect the sliding ring 15 and the L-shaped block 18. When the sliding ring 15 slides, it drives the L-shaped block 18 to rotate, converting the linear motion into the rotation of the L-shaped block 18 and realizing the transmission of force.

[0039] Two L-shaped blocks 18 are rotatably connected to opposite sides of the two connecting rods 17. The L-shaped blocks 18 connect the connecting rods 17 and the moving blocks 19. Their rotation causes the moving blocks 19 to slide, thereby moving the clamping blocks 20. This ensures that the clamping blocks 20 move the appropriate distance to clamp the different sensors 12. The tops of the two L-shaped blocks 18 are rotatably connected to the moving blocks 19. The moving blocks 19 connect the L-shaped blocks 18 and the clamping blocks 20. When the L-shaped blocks 18 rotate, they slide along the top of the mover 13, causing the clamping blocks 20 to move closer to or away from the sensors 12, thus achieving clamping. Alternatively, the two movable blocks 19 can be loosened. Each adjacent side of the two movable blocks 19 is fixedly connected to a clamping block 20. The clamping block 20 contacts the sensor 12 to generate a clamping force, preventing it from shaking or falling off. This adapts to pipeline vibration, ensures that the sensor 12 can stably collect data, and guarantees data accuracy. The two L-shaped blocks 18 are externally rotatably connected to the inside of the mover 13. The L-shaped blocks 18 rotate inside the mover 13, which provides a fulcrum for them and limits their rotation range, ensuring that they can accurately drive the movable blocks 19 and clamping blocks 20 to move, thus ensuring fixed stability.

[0040] The two connecting rods 17 are externally slidably connected to the inside of the mover 13. The connecting rods 17 slide within the mover 13, which provides space and guidance to prevent offset and ensure accurate transmission of motion to the L-shaped block 18, making the transmission reliable. The top of the fixed rod 16 is fixedly connected to the inner wall of the mover 13. The fixed rod 16 is fixed to the mover 13, providing stable support for the sliding ring 15, preventing it from shaking and affecting the transmission accuracy, and ensuring the fixing effect of the clamping block 20. The bottoms of the two moving blocks 19 are slidably connected to the top of the mover 13. The moving blocks 19 slide on the top of the mover 13, which provides a track for them. This ensures that the movement is in a straight line, allowing the clamping blocks 20 to smoothly approach or move away from the sensor 12, achieving stable clamping. The adjacent sides of the two clamping blocks 20 are in contact with the outside of the sensor 12. The clamping force generated by the contact between the clamping blocks 20 and the sensor 12 fixes its position, preventing data deviation caused by shaking during detection, ensuring data consistency, and providing a reliable basis for pipeline analysis. The external sliding connection of the sliding ring 15 is inside the mover 13. The sliding ring 15 slides inside the mover 13, which limits its movement to prevent it from deviating from the track, ensuring that the driving force of the electric push rod 14 is effectively transmitted to the connecting rod 17, and ensuring the normal operation of the fixing assembly.

[0041] Working principle: When it is necessary to disassemble the testing machine 1 and the protective shell 2, the square slider 7 is slidable. The sliding of the square slider 7 will cause the sliding block 6 to slide inside the testing machine 1. The sliding of the sliding block 6 will cause the base plate 5 and the sliding rod 3 to slide. At this time, the triangular block at the top of the sliding block 6 will disengage from the inner wall of the slot 9 opened on the outside of the protruding block 8. At this time, the protruding block 8 is no longer limited inside the protective shell 2. The testing machine 1 can then be disassembled from the top of the protective shell 2, which makes it convenient for the staff to inspect the inside of the testing machine 1, so as to ensure that the inner wall of the testing machine 1 maintains normal operation for a long time.

[0042] When it is necessary to fix sensors 12 of different sizes, the sensor 12 is existing technology and will not be described in detail here. One end of the connecting line 11 is connected to the detection machine 1, and the other end is connected to the sensor 12 to transmit and collect data to realize signal connection. The sensor 12 is placed on the top of the mover 13. The electric push rod 14 drives the sliding ring 15 to slide along the fixed rod 16. The sliding ring 15 drives the connecting rod 17 to rotate, so that the L-shaped block 18 is linked with the moving block 19, and the clamping block 20 clamps the sensor 12 to prevent shaking. The mover 13 provides a platform for the sensor 12 and drives it to move along the pipeline, expanding the detection range and ensuring that the sensor 12 stably collects data such as pipeline temperature and pressure and transmits it to the detection machine 1. It ensures that the sensor 12 is installed in a stable position, avoids data acquisition deviation caused by shaking during detection, and ensures the accuracy and consistency of detection data. It provides a reliable basis for the analysis of the operating status of thermal pipelines. There is no need to adjust the fixing structure for different sizes, which improves installation efficiency, reduces operation time, reduces the risk of sensor 12 falling off, and the stable fixation can adapt to pipeline vibration and other working conditions, ensuring the continuous detection process and improving the overall reliability of the device.

[0043] When it is necessary to inspect the inside of the thermal production pipeline, the mover 13 is placed inside the thermal pipeline. Then, the movement of the mover 13 inside the thermal pipeline is controlled by the control panel on the top of the inspection machine 1 via the connecting line 11. When the sensor 12 detects that the wall thickness is reduced or cracks appear inside the thermal pipeline, the condition inside the pipeline is transmitted to the control panel on the surface of the inspection machine 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
