Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pump inspection, and in particular to a ground source heat pump inspection device. Background Art

[0002] Ground Source Heat Pump (GSHP) is a highly efficient heating and cooling technology that uses the relatively stable temperature of the ground to achieve energy transfer. The system is mainly composed of underground pipelines, heat pump host, water circulation system and control system. The underground pipeline is usually buried underground and extracts or discharges heat through heat exchange with groundwater or soil.

[0003] In the prior art, it is usually necessary to manually go down the well to inspect and observe the appearance and connection of the buried pipeline. This method is time-consuming and labor-intensive, and there are safety hazards. Specifically, there are many limitations to manual inspections in the well. The internal space of the inspection well is often limited, and the environment is complex, which makes it difficult for inspectors to fully inspect all key parts. Secondly, there may be toxic and harmful gases, lack of oxygen, humidity and other dangerous factors inside the inspection well, which pose a threat to the health of inspectors.

[0004] In summary, how to solve the problem of safety hazards caused by the need for manual inspection in the prior art has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a ground source heat pump inspection device. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a ground source heat pump inspection device. Through the design of the chain belt structure and the use of various components, the inspection of the pipeline system can be carried out on the ground without manual downhole, thereby avoiding people from entering dangerous environments and improving safety.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a ground source heat pump inspection device, comprising an inspection well with an arc-shaped bottom, a pipeline system passing through the inside of the inspection well, the center of the arc of the inspection well coincides with the center of the pipeline system, and an inspection component for detecting the pipeline system is provided in the inspection well.

[0007] The inspection component includes a controller and a number of chain links. Adjacent chain links can be detachably connected to form a strip-shaped chain belt. Electromagnets are fixedly connected to both ends of the chain belt, and the controller is used to control the operation of the electromagnets. The chain belt is installed on the outer wall of the pipeline system, and the chain belts on the upper and lower sides of the pipeline system are connected by electromagnets to form a ring that matches the outer surface of the pipeline system.

[0008] A plurality of telescopic parts are fixedly connected to the outer wall of the chain belt close to the pipeline system, and the controller is used to control the operation of the telescopic parts; the telescopic parts are evenly spaced on the outer wall of the chain belt. When the chain belt is installed, the telescopic parts are located on the side close to the pipeline system, and the output shafts of the telescopic parts are fixedly connected with temperature sensors and acoustic wave detectors, and the controller is used to receive and store signals from the temperature sensors and acoustic wave detectors.

[0009] The outer wall of the chain belt located between adjacent telescopic parts is also provided with a moving component for moving the chain belt and an adsorption component for fitting the chain belt to the pipeline system; the outer wall of the chain belt close to the arc-shaped side of the inspection well is provided with a supporting component for providing supporting force for the chain belt.

[0010] The technical principles of the above scheme are as follows:

[0011] Since the chain belt is composed of several detachably connected chain links, the chain links can be assembled or disassembled, so that the chain belt is suitable for pipeline system detection of different pipe diameters. Since the bottom of the inspection well is arc-shaped, and the center of the arc coincides with the center of the pipeline system; therefore, the chain belt below the pipeline system can be sent into the arc structure first, and the lower chain belt can be supported by the support component first. After the lower chain belt is successfully installed, the chain belt above the pipeline system is connected through the electromagnet to form a ring around the outer wall of the pipeline system. Then, the adsorption component is used to make the inner side of the chain belt fit with the pipeline system. After the fitting is completed, the temperature sensor and the acoustic wave detector are pressed against the outer wall of the pipeline system using the telescopic parts. The temperature information in the pipeline system is detected by the temperature sensor, and the internal and external temperature difference of the pipeline system is analyzed and judged to be normal, and the temperature of the outer insulation layer of the pipeline system is detected to be normal. The sound wave detector is used to judge the sound produced by fluid flow and the abnormal sound produced by leakage. When there is a leak in the pipeline system, the fluid escapes from the pipeline and generates sound waves in the surrounding medium, thereby determining the location of the leak point. In this process, the chain belt is driven to move horizontally by moving the components, thereby achieving all-round detection of the pipeline system.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The present invention, through the design of the chain belt structure and the use of various components, enables the detection of the pipeline system to be carried out on the ground without the need for manual work, thereby avoiding personnel from entering a dangerous environment and improving safety. In addition, during the inspection process, if a leak or other fault is found, manual operation may cause secondary damage; this device can immediately stop the operation when a problem is found, reducing the risk. In addition, automatic operation is achieved through electromagnets, detectors and controllers, reducing manual intervention and reducing safety hazards caused by human errors.

[0014] 2. The present invention can accurately detect the temperature information in the pipeline system, the sound generated by the fluid flow, and the abnormal sound caused by leakage through the combined use of temperature sensors and acoustic wave detectors. This helps to promptly discover abnormal conditions in the pipeline system, such as abnormal temperature differences between the inside and outside, abnormal temperature of the outer insulation layer, and leakage. When a leak is detected, the acoustic wave detector can accurately determine the location of the leak point, providing an important basis for subsequent repairs and maintenance, and can take timely measures to deal with it, reducing the possibility of unexpected situations.

[0015] 3. Since the chain belt of the present invention is composed of a number of detachably connected chain links, it can be easily assembled and disassembled to adapt to pipeline systems of different diameters; this design enables the detection system to be widely used in pipelines of various sizes, thereby improving the versatility and flexibility of the system.

[0016] Furthermore, the moving assembly includes a plurality of electric pulleys, which are fixedly connected to the outer wall of the chain belt. When the chain belt is installed, the electric pulley is located on a side close to the pipeline system, and the controller is used to control the operation of the electric pulley.

[0017] Beneficial effects: By adjusting the speed and direction of the electric pulley, the chain belt can be driven to move horizontally and rotate around the pipeline system, so that detection along and around the pipeline can be carried out; the detection data is further increased, and the corresponding sensors can be installed according to the data to be detected, so as to realize multi-directional detection of the pipeline system. In addition, the use of the electric pulley realizes the automation of the detection process, reduces the dependence on manual labor, and improves the efficiency and accuracy of detection.

[0018] Furthermore, the adsorption assembly includes a plurality of electric suction cups, which are fixedly connected to the outer wall of the chain belt. When the chain belt is installed, the electric suction cups are located on a side close to the pipeline system, and the controller is used to control the operation of the electric suction cups.

[0019] Beneficial effects: Through the design of the electric suction cup, the chain belt can be tightly adsorbed on the outer wall of the pipeline system after moving to the appropriate position, ensuring the fit and stability between the chain belt and the pipeline system; it helps to improve the detection accuracy of the temperature sensor and the ultrasonic detector and reduce the errors caused by poor fit.

[0020] Furthermore, the support assembly includes an air transmission system and a plurality of support airbags, and the controller is used to control the operation of the air transmission system; the support airbags are all fixedly connected to the outer wall of the chain belt; the support airbags are all distributed at equal intervals, and the support airbags are all connected to the air transmission system; a first solenoid valve is provided at the connection point between the support airbags and the air transmission system, and a plurality of pressure sensors are fixedly connected to the outer wall of the chain belt close to the pipeline system, and the pressure sensors are all arranged at equal intervals. The controller is used to receive the pressure signal emitted by the pressure sensor, and control the operation of the first solenoid valve based on the pressure signal, thereby controlling the support airbags to be inflated sequentially starting from the end.

[0021] Beneficial effect: When the chain belt under the pipeline system is sent to the same level as the arc apex, the gas medium is transmitted from the outside through the gas transmission system, and the first solenoid valve connecting the support airbag and the gas transmission system is opened, so that the support airbag at the head end is filled with gas, and then the gas is transmitted in sequence, and the subsequent first solenoid valves are gradually opened to transmit the gas to the subsequent support airbags. When the pressure sensor detects that the chain belt is in contact with the pipeline system, the gas transmission system and the first solenoid valve are closed, so that the equipment installed on the chain belt is in contact with the outer wall of the pipeline system, further ensuring the stability of the chain belt during the detection process, and avoiding detection failures caused by shaking or falling off. In addition, the pressure sensors distributed at equal intervals can ensure effective contact in each area on the one hand, and adjust the support airbag based on pressure to ensure uniform contact force in each area on the other hand. At the same time, based on the pressure detected by the pressure sensor, the inflation amount of each support airbag is adjusted, and the tightness between the chain belt and the pipeline system can be adjusted to ensure that the chain belt as a whole can slide normally along the pipeline system when the subsequent electric pulley is driven.

[0022] Furthermore, a detection airbag for detecting air tightness is fixedly connected to the side wall of the chain belt. When detecting air tightness, the ring-shaped chain belt is respectively installed on both sides of the connection of the pipeline system; after the detection airbag is installed, the upper outlet of the connection of the pipeline system is blocked by a blocking cover plate; the input ends of the detection airbags are connected to the gas transmission system, and the output ends of the detection airbags are connected to the side of the pipeline system close to the connection. A second solenoid valve is provided at the input and output ends of the detection airbags, and the controller is used to control the operation of the second solenoid valve; an air pressure sensor is fixedly connected to the detection airbag close to the side of the chain belt. When detecting air tightness, the air pressure sensor is located between the two detection airbags, and the controller is used to receive and store the air pressure sensor signal.

[0023] Beneficial effects: The gas supply system is used to inflate the inside of the detection airbags, which are installed in a ring shape at the connection of the pipeline system. As the gas is continuously filled, the detection airbags gradually expand and fit tightly to the inner wall of the inspection well, forming a closed space on both sides of the connection and blocking the outlet above the connection. After the blocking is completed, the pressure change in the closed space is monitored in real time through the air pressure sensor. If an abnormal pressure is detected, the controller will determine that there may be a leak at the connection. At this time, the controller can issue an alarm or record relevant data for subsequent analysis and processing.

[0024] Furthermore, when sealing the outlet above the connection of the pipeline system, a sealing cover is used for sealing, and a sealant is filled in the gap position.

[0025] Beneficial effect: The internal space of the detection area is sealed by the sealing cover and the sealant, making the detection more accurate.

[0026] Furthermore, when detecting the connection of the pipeline system, the controller controls the electric pulley to drive the chain belts on both sides to move toward the connection of the pipeline system.

[0027] Beneficial effect: The connection of the pipeline system is squeezed by the electric pulley. When there is no leakage, the electric pulley will not move. If it can be squeezed and moved, it means that there may be leakage at the connection. Through this combination, the accuracy of the detection structure is further improved.

[0028] Furthermore, the chain belt at the head end is also detachably connected to an operating rod via an electromagnet.

[0029] Beneficial effects: Through the design of the operating lever, the operating lever can assist technicians in sending the chain belt into the arc structure of the inspection well. Especially in the case of narrow space or difficult operation, the operating lever can provide additional support and control, further increasing the convenience of device operation.

[0030] Furthermore, the controller also includes a wireless communication module, which is used to transmit the detection data of the temperature sensor, the acoustic wave detector, the pressure sensor and the air pressure sensor to the remote monitoring terminal in real time, and the remote monitoring terminal is used to display the detection data and generate a detection report.

[0031] Beneficial effects: By adding a wireless communication module, real-time transmission of detection data can be achieved, allowing technicians to view and analyze data in real time on the remote monitoring terminal. This not only improves the efficiency of detection, but also facilitates timely discovery and handling of problems. The remote monitoring terminal can be a computer, tablet computer, or smart phone, which can display detection data and generate detection reports for easy recording and archiving. In addition, the energy consumption contradictions of the heat pump system in different seasons and different environments can be specifically analyzed by analyzing the stored data, so that the heat pump system can adjust its working state according to different environmental parameters.

[0032] Furthermore, a plurality of cleaning brushes are fixedly connected to the outer wall of the chain belt close to the pipeline system, and the cleaning brushes are in contact with the outer wall of the pipeline system.

[0033] Beneficial effect: The cleaning brush is fixedly connected to the outer wall of the chain belt, which can clean the outer wall of the pipeline system while testing. This can not only remove the attached dirt and sediment, but also improve the accuracy and reliability of the test. When the controller controls the electric pulley to drive the chain belt to move, the cleaning brush simultaneously cleans the outer wall of the pipeline system, ensuring that the outer wall of the pipeline system is clean, which is conducive to subsequent testing work.

[0034] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following is further described in detail through specific implementation methods:

[0041] Embodiment 1:

[0042] As attached Figure 1-Figure 4 Shown is a ground source heat pump inspection device, comprising an inspection well 1 with an arc-shaped bottom, a pipeline system 2 passing through the inside of the inspection well 1, the center of the arc of the inspection well 1 coincides with the center of the pipeline system 2, and an inspection component for detecting the pipeline system 2 is provided in the inspection well 1.

[0043] The inspection component includes a controller and a number of chain links. Adjacent chain links can be detachably snap-connected to form a strip-shaped chain belt 3; the chain belt 3 is fixedly connected with electromagnets 4 at both ends by screws, and the controller is used to control the operation of the electromagnets 4; the chain belt 3 is installed on the outer wall of the pipeline system 2, and the chain belts 3 on the upper and lower sides of the pipeline system 2 are connected by electromagnets 4 to form a ring that matches the outer surface of the pipeline system 2.

[0044] like Figure 1 As shown, the outer wall of the inner chain belt 3 is fixedly connected with a plurality of telescopic parts by screws. In this embodiment, the telescopic parts are electric telescopic rods 5, and the controller is used to control the operation of the electric telescopic rods 5; the electric telescopic rods 5 are evenly spaced and distributed on the outer wall of the chain belt 3. When the chain belt 3 is installed, the electric telescopic rods 5 are located on the side close to the pipeline system 2, and the output shafts of the electric telescopic rods 5 are bonded and fixed with temperature sensors and acoustic wave detectors, and the controller is used to receive and store the signals of the temperature sensor and the acoustic wave detector.

[0045] The outer wall of the chain belt 3 located between adjacent electric telescopic rods 5 is also provided with a moving component for moving the chain belt 3 and an adsorption component for fitting the chain belt 3 to the pipeline system 2; the outer wall of the lower chain belt 3 is provided with a supporting component for providing supporting force for the chain belt 3.

[0046] like Figure 4 As shown, the moving assembly includes a number of electric pulleys 6, which are all screwed and fixed to the outer wall of the chain belt 3. When the chain belt 3 is installed, the electric pulley 6 is located on the side close to the pipeline system 2, and the controller is used to control the operation of the electric pulley 6. By adjusting the rotation speed and direction of the electric pulley 6, the chain belt 3 can be driven to move laterally and rotate around the pipeline system 2, so that detection along the pipeline and around the pipeline can be performed in this way; so that the detection data is further increased, and the corresponding sensors can be installed according to the data to be detected, so as to realize multi-directional detection of the pipeline system 2. In addition, the use of the electric pulley 6 realizes the automation of the detection process, reduces the dependence on manual labor, and improves the efficiency and accuracy of detection.

[0047] like Figure 4 As shown, the adsorption assembly includes a plurality of electric suction cups 7, which are all screwed and fixed to the outer wall of the chain belt 3. When the chain belt 3 is installed, the electric suction cups 7 are located on the side close to the pipeline system 2, and the controller is used to control the operation of the electric suction cups 7. Through the design of the electric suction cups 7, the chain belt 3 can be tightly adsorbed on the outer wall of the pipeline system 2 after moving to a suitable position, ensuring the fit and stability between the chain belt 3 and the pipeline system 2; it helps to improve the detection accuracy of the temperature sensor and the acoustic wave detector, and reduce the error caused by poor fit.

[0048] like Figure 1 As shown, the support assembly includes an air delivery system and a plurality of support airbags 8. In this embodiment, the air delivery system is an air pump, and the controller is used to control the operation of the air pump; the support airbags 8 are all fixedly bonded to the outer wall of the chain belt 3, and the support airbags 8 are all distributed at equal intervals. Preferably, a support airbag 8 is provided for each chain link, and the support airbags 8 are all connected to the air pump. A first solenoid valve is provided at the connection point between the support airbags 8 and the air pump. A plurality of pressure sensors are fixedly connected to the outer wall of the chain belt 3 near the pipeline system 2 with screws. The pressure sensors are all arranged at equal intervals, and are preferably arranged one by one with the support airbags. The controller is used to receive the pressure signal emitted by the pressure sensor, and control the operation of the first solenoid valve based on the pressure signal, so as to control the support airbags 8 to be inflated sequentially starting from the end.

[0049] When the chain belt 3 under the pipeline system 2 is fed in until it is flush with the apex of the arc, the gas medium is transmitted from the outside through the air pump, and the first solenoid valve connecting the support airbag 8 at the head end and the air pump is opened, so that the support airbag 8 at the head end is filled with gas, and then the subsequent first solenoid valves are gradually opened to transmit the gas to the subsequent support airbags 8, and the inflation of the subsequent adjacent support airbags 8 is completed in sequence. When the pressure sensor detects that the chain belt 3 is in contact with the pipeline system 2, the air pump and the first solenoid valve are closed, so that the equipment installed on the chain belt 3 is in contact with the outer wall of the pipeline system 2, further ensuring the stability of the chain belt 3 during the detection process, and avoiding detection failures caused by shaking or falling off. In addition, the pressure sensors distributed at equal intervals can ensure effective contact in each area on the one hand, and adjust the support airbag 8 based on pressure to ensure uniform contact force in each area on the other hand. At the same time, based on the pressure detected by the pressure sensor, the inflation volume of each support airbag 8 is adjusted, so that the tightness between the chain belt 3 and the pipeline system 2 can be adjusted to ensure that the chain belt 3 as a whole can slide normally along the pipeline system 2 when the electric pulley 6 is driven subsequently.

[0050] The chain belt 3 at the head end is also detachably connected to an operating rod (not shown in the drawings) through an electromagnet 4. The design of the operating rod can assist technicians in sending the chain belt 3 into the arc structure of the inspection well 1, especially in the case of narrow space or difficult operation, the operating rod can provide additional support and control, further increasing the convenience of device operation.

[0051] The specific implementation process is as follows: First, when the ground source heat pump is installed, the inspection well 1 is pre-buried in the soil layer, and the key components of the heat pump system are mainly installed in the inspection well 1, and monitoring points are set at multiple key positions to cover all aspects of the heat pump system and improve the detection accuracy and efficiency. Since the chain belt 3 is composed of a number of detachable and snap-connected chain links, the chain links can be assembled or disassembled so that the chain belt 3 is suitable for the detection of pipeline systems 2 with different pipe diameters. Since the bottom of the inspection well 1 is arc-shaped, and the center of the arc coincides with the center of the pipeline system 2; therefore, the chain belt 3 below the pipeline system 2 can be sent into the arc structure through the operating rod, and the lower chain belt 3 can be supported by the support airbag 8. After the lower chain belt 3 is successfully installed, the chain belt 3 above the pipeline system 2 is connected to the lower part through the electromagnet 4, so that the upper and lower chain belts 3 are connected to form a ring around the outer wall of the pipeline system 2.

[0052] Then use the electric suction cup 7 to make the inner side of the chain belt 3 and the pipeline system 2 fit each other. After the fitting is completed, use the electric telescopic rod 5 to press the temperature sensor and the acoustic wave detector against the outer wall of the pipeline system 2. Use the temperature sensor to detect the temperature information in the pipeline system 2, analyze and determine whether the temperature difference between the inside and outside of the pipeline system 2 is normal, and detect whether the temperature of the outer insulation layer of the pipeline system 2 is normal. Use the acoustic wave detector to determine the sound generated by the flow of the fluid and the abnormal sound caused by the leakage. When there is a leak in the pipeline system 2, the fluid escapes from the pipeline and generates sound waves in the surrounding medium, thereby determining the location of the leak point. In this process, by controlling the electric pulley 6, the chain belt 3 is driven to move horizontally, thereby achieving all-round detection of the pipeline system 2.

[0053] The present invention enables the detection of the pipeline system 2 to be carried out on the ground through the design of the chain belt 3 structure and the use of various components, without the need for manual downhole operations, thereby avoiding personnel from entering dangerous environments and improving safety. In addition, during the inspection process, if a leak or other fault is found, manual operation may cause secondary damage; this device can immediately stop the operation when a problem is found, reducing risks. Through the combined use of temperature sensors and acoustic wave detectors, the temperature information in the pipeline system 2, the sound generated by the flow of the fluid, and the abnormal sound generated by the leak can be accurately detected. This helps to promptly detect abnormal conditions in the pipeline system 2, such as abnormal temperature differences between the inside and outside, abnormal temperature of the outer insulation layer, and leaks. When a leak is detected, the acoustic wave detector can accurately determine the location of the leak point, providing an important basis for subsequent repairs and maintenance.

[0054] Embodiment 2:

[0055] As attached Figure 2 As shown, the difference from the above embodiment is that a detection airbag 9 for detecting air tightness is also fixedly bonded to the side wall of the chain belt 3. When detecting air tightness, the ring-shaped chain belt 3 is respectively installed on both sides of the connection of the pipeline system 2; after the detection airbag 9 is installed, the upper outlet of the connection of the pipeline system 2 is blocked by a blocking cover plate; the input ends of the detection airbag 9 are connected to the gas transmission system, and the output ends of the detection airbag 9 are connected to the side of the pipeline system 2 close to the connection, and the input and output ends of the detection airbag 9 are both provided with a second solenoid valve, and the controller is used to control the operation of the second solenoid valve; an air pressure sensor is fixedly bonded to the detection airbag 9 close to the side of the chain belt 3, and the air pressure sensor is located between the two detection airbags 9 when detecting air tightness, and the controller is used to receive and store the air pressure sensor signal.

[0056] The specific implementation process is as follows: the detection airbags 9 are inflated through the gas transmission system. These detection airbags 9 are installed in a ring shape at the connection of the pipeline system 2. As the gas is continuously filled, the detection airbags 9 gradually expand and fit tightly to the inner wall of the inspection well 1, so that a closed space is formed on both sides of the connection, and the outlet above the connection is blocked. After the blocking is completed, the pressure change in the closed space is monitored in real time by the air pressure sensor. If an abnormal pressure is detected, the controller will determine that there may be a leak at the connection. At this time, the controller can issue an alarm or record relevant data for subsequent analysis and processing.

[0057] Embodiment 3:

[0058] As attached Figure 2 As shown, the difference from the above embodiment is that when sealing the upper outlet of the connection of the pipeline system 2, a sealing cover plate is used for sealing, and a sealant is filled in the gap position.

[0059] The specific implementation process is as follows: the bottom of the blocking cover is arc-shaped, and the arc-shaped surface contacts the detection airbag 9 after expansion. A pipe hole that matches the connection of the pipeline system 2 is opened in the middle of the blocking cover, and a sealing ring is set at the position of the pipe hole; and the blocking cover is composed of several pieces. After the blocking cover is installed, the gap position is filled with sealant. The internal space of the detection area is sealed by the blocking cover and the sealant, making the detection more accurate.

[0060] Embodiment 4:

[0061] As attached Figure 2 As shown, the difference from the above embodiment is that when detecting the connection of the pipeline system 2, the controller also controls the electric pulley 6 to drive the chain belts 3 on both sides to move toward the connection of the pipeline system 2.

[0062] The specific implementation process is as follows: the connection of the pipeline system 2 is squeezed by the electric pulley 6. When no leakage occurs, the electric pulley 6 is squeezed and does not move. If it can be squeezed and moved, it means that there may be leakage at the connection. Through this combination, the accuracy of the detection structure is further improved.

[0063] Embodiment 5:

[0064] The difference from the above embodiment is that the controller also includes a wireless communication module, which is used to transmit the detection data of the temperature sensor, acoustic wave detector, pressure sensor and air pressure sensor to the remote monitoring terminal in real time, and the remote monitoring terminal is used to display the detection data and generate a detection report.

[0065] The specific implementation process is as follows: By adding a wireless communication module, real-time transmission of detection data can be achieved, allowing technicians to view and analyze data in real time on the remote monitoring terminal. This not only improves the efficiency of detection, but also facilitates timely discovery and handling of problems. The remote monitoring terminal can be a computer, tablet computer, or smart phone, which can display detection data and generate detection reports for easy recording and archiving. In addition, the energy consumption contradictions of the heat pump system in different seasons and different environments can be analyzed in detail by analyzing the stored data, so that the heat pump system can adjust its working state according to different environmental parameters.

[0066] Embodiment 6:

[0067] The difference from the above embodiment is that a plurality of cleaning brushes 10 are screw-fixedly connected to the outer wall of the chain belt 3 close to the pipeline system 2 , and the cleaning brushes 10 are in contact with the outer wall of the pipeline system 2 .

[0068] The specific implementation process is as follows: the cleaning brush 10 is fixedly connected to the outer wall of the chain belt 3 with screws, so that the outer wall of the pipeline system 2 can be cleaned while testing. This can not only remove the attached dirt and sediment, but also improve the accuracy and reliability of the test. When the controller controls the electric pulley 6 to drive the chain belt 3 to move, the cleaning brush 10 simultaneously cleans the outer wall of the pipeline system 2 to ensure that the outer wall of the pipeline system 2 is clean, which is conducive to subsequent testing work.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
