Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology and relates to a municipal pipeline inspection device. Background Technology

[0002] In urban infrastructure construction, municipal pipelines play a vital role in water supply, drainage, and gas transmission. Their quality and safety directly affect the normal operation of the city and the quality of life of residents. However, during long-term use, municipal pipelines are affected by various factors, such as soil pressure, groundwater erosion, corrosion of the media inside the pipeline, and temperature changes. These factors may cause defects such as cracks, deformation, and corrosion perforation in the pipelines, leading to leakage accidents. This not only wastes resources and pollutes the environment but may also damage surrounding buildings and underground facilities, and even endanger public safety.

[0003] Therefore, regular inspection of municipal pipelines to promptly identify and repair potential defects is a crucial step in ensuring their safe operation. Currently, common municipal pipeline inspection methods mainly include visual inspection, non-destructive testing (NDT), and pressure testing. Visual inspection primarily involves observing the pipeline surface manually or with simple tools. While simple and easy to perform, this method can only detect obvious surface defects and struggles to detect hidden defects inside the pipeline. Non-destructive testing techniques, such as ultrasonic testing, X-ray testing, and magnetic particle testing, can detect internal pipeline defects, but the equipment is complex, the operation is demanding, and the testing costs are high, limiting their effectiveness for inspecting large pipelines or pipelines in complex environments.

[0004] Pressure testing is a method of assessing pipeline strength and sealing by applying pressure to the pipeline and observing its deformation and leakage under pressure. Traditional pressure testing methods typically involve installing sealing devices at both ends of the pipeline, injecting a medium such as water or gas into the pipeline, gradually increasing the pressure to a specified level, maintaining this pressure for a certain period, and then observing pressure changes and pipeline leakage. However, traditional pressure testing can only perform a holistic inspection of the entire pipeline system, making it difficult to target specific parts of the pipeline. For long-distance pipelines or pipelines with localized weak points, it is impossible to accurately determine the exact location of defects, posing challenges to subsequent maintenance work.

[0005] In response to the problems mentioned above, this utility model proposes a municipal pipeline inspection device. Utility Model Content

[0006] In view of this, in order to solve the problem that existing traditional pressure testing can only perform overall testing of the entire pipeline system and is difficult to perform targeted testing of specific parts of the pipeline, this utility model provides a municipal pipeline testing device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a municipal pipeline inspection device, including a base, a positioning ring fixedly installed on the top of the base, a pipeline body being clamped onto the positioning ring, and a moving mechanism installed on the top of the base, the bottom of the moving mechanism extending into the pipeline body. The inspection device also includes:

[0008] The pressure testing mechanism is installed at the bottom of the moving mechanism and is in contact with the inner wall of the pipe body;

[0009] A transmission mechanism installed on the pressure testing unit is used to transmit hydraulic oil to the pressure testing unit in order to perform pressure testing on the pipeline body.

[0010] Furthermore, the moving mechanism includes two mounting rods symmetrically fixedly installed on the top of the base. Support screws are fixedly installed at the top of the mounting rods, and a connecting frame located above the pipe body is sleeved on the two support screws. Two mounting boxes are symmetrically fixedly installed on the connecting frame, and a power assembly is installed inside each mounting box. The top of the power assembly extends to the outside of the mounting box and is connected to the connecting frame and the support screws respectively. A support rod is fixedly installed at the bottom of the mounting box, and the bottom end of the support rod is connected to the pressure testing mechanism. The beneficial effects are: the connecting frame, two mounting boxes, and two support rods provide support for the pressure testing mechanism. Furthermore, activating the two power assemblies drives the connecting frame to move longitudinally along the two support screws, thereby driving the pressure testing mechanism to move longitudinally. This allows for adjustment of the pressure testing mechanism's position, enabling testing at different locations on the pipe body.

[0011] Furthermore, the power assembly includes a first drive motor fixedly installed inside the mounting box. The output shaft of the first drive motor extends above the connecting frame and is fixedly fitted with a drive gear. It also includes a threaded ring that passes through the connecting frame and is rotatably connected to the connecting frame. A support screw passes through the corresponding threaded ring and is threadedly connected to the inner wall of the threaded ring. A driven gear located above the connecting frame is fixedly fitted on the threaded ring. The drive gear meshes with the driven gear. The beneficial effect is that by starting the first drive motor, the drive gear is driven to rotate. At this time, under the meshing transmission action with the driven gear, the threaded ring can be driven to rotate. When the threaded ring rotates, under the threaded transmission action with the support screw, the connecting frame can be driven to move longitudinally. This can drive the pressure testing mechanism to move longitudinally, thereby facilitating the detection of different positions inside the pipeline.

[0012] Furthermore, the pressure testing mechanism includes a connecting plate fixedly installed at the bottom of two support rods. A delivery pipe is fixedly installed through the connecting plate. A transmission mechanism is installed on the top of the connecting plate and connected to the delivery pipe. A base plate is fixedly installed at the bottom of the delivery pipe. Multiple flow holes are evenly spaced on the inner wall of the delivery pipe. A corrugated hose is fixedly installed on the top of the base plate, and the top of the corrugated hose is fixedly connected to the bottom of the connecting plate. The beneficial effect is that hydraulic oil flows through the multiple flow holes on the delivery pipe into the closed space formed by the connecting plate, the base plate, and the corrugated hose. The hydraulic oil then expands the corrugated hose, allowing it to compress the inner wall of the pipe body, thereby enabling pressure testing of the inner wall of the pipe body.

[0013] Furthermore, a first support mesh ring and a second support mesh ring located inside the first support mesh ring are fixedly installed on the bottom of the connecting plate. The bottom of the first support mesh ring and the bottom of the second support mesh ring are both fixedly connected to the top of the base plate. Beneficial effect: Setting the first support mesh ring and the second support mesh ring can improve the stability when the connecting plate is connected to the base plate, so that when conveying hydraulic oil, only the corrugated hose can be squeezed.

[0014] Furthermore, the transmission mechanism includes a hydraulic tank fixedly installed on the top of the connecting plate. An installation pipe is fixedly installed on the bottom inner wall of the hydraulic tank. The bottom end of the installation pipe extends into the conveying pipe and is fixedly connected to the inner wall of the conveying pipe. Hydraulic oil is provided in the hydraulic tank. A pushing component is installed on the top of the hydraulic tank. The bottom of the pushing component extends into the hydraulic tank and is connected to a push plate. The push plate is tightly slidably connected to the inner wall of the hydraulic tank. Beneficial effect: By activating the pushing component, the push plate can be driven to move downward, which can push the hydraulic oil into the conveying pipe to expand the corrugated hose.

[0015] Furthermore, the pushing component includes a second drive motor fixedly mounted on the top of the hydraulic tank. A transmission screw is fixedly mounted on the output shaft of the second drive motor, a transmission frame is sleeved on the transmission screw, a transmission nut is fixedly mounted on the top of the transmission frame, the transmission screw passes through the transmission nut and is threadedly connected to the transmission nut, connecting covers are fixedly mounted at equal intervals on the top of the push plate, pressure sensors are fixedly mounted on the bottom inner wall of the connecting covers, the top of the connecting covers passes through the top inner wall of the hydraulic tank and extends to the top of the hydraulic tank, a transmission rod is slidably connected inside the connecting cover, the top end of the transmission rod extends to the top of the connecting cover and is fixedly connected to the bottom of the transmission frame; Beneficial effects: Through The second drive motor is started, which drives the transmission screw to rotate. Under the threaded transmission with the transmission nut, the transmission frame moves downward, which in turn drives multiple transmission rods downward. Through the connecting cover, the push plate moves downward, thus pushing the hydraulic oil. When the transmission rods drive the connecting cover, they can press the pressure sensor. After being subjected to pressure, the pressure sensor can detect the pressure. The pressure sensor is connected to an external display wirelessly, so that the detected pressure data can be transmitted to the display screen. This allows for control of the pressure data to be detected when inspecting the pipeline body.

[0016] Furthermore, multiple support boxes are fixedly installed at equal intervals on the top of the base. A movable plate is slidably connected inside the support box. An adjusting nut is fixedly installed on one side of the movable plate. The top of the movable plate extends to the top of the support box and is fixedly installed with a clamping plate. The clamping plate is used to clamp and position the pipe body. An adjusting screw is rotatably connected to the inner wall of one side of the support box. One end of the adjusting screw passes through the movable plate, the adjusting nut, and the inner wall of the other side of the support box and extends to the outside of the support box. The adjusting screw is threadedly connected to the adjusting nut. Beneficial effect: By rotating the adjusting screw, under the threaded transmission action with the adjusting nut, the movable plate can be driven to move laterally. At this time, the clamping plate can be driven closer to the pipe body until the pipe body is clamped and positioned by the clamping plate, thereby preventing the pipe body under inspection from shifting.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The municipal pipeline testing device disclosed in this utility model, through the set moving mechanism, can be set with a connecting frame, two mounting boxes and two support rods to support the pressure testing mechanism. Furthermore, by activating the two power components, the connecting frame can be driven to move longitudinally along the two support screws, thereby driving the pressure testing mechanism to move longitudinally. Thus, by adjusting the position of the pressure testing mechanism, different positions of the pipeline body can be tested.

[0019] 2. The municipal pipeline testing device disclosed in this utility model, through the pressure testing mechanism, allows hydraulic oil to flow into the closed space formed by the connecting plate, the bottom plate and the corrugated hose through multiple flow holes on the delivery pipe. Then the hydraulic oil can expand the corrugated hose, which can then be used to squeeze the inner wall of the pipeline body, thereby achieving pressure testing of the inner wall of the pipeline body.

[0020] 3. The municipal pipeline inspection device disclosed in this utility model, through the transmission mechanism, can drive the push plate to move downward by activating the push component, which can push the hydraulic oil into the delivery pipe to expand the corrugated hose.

[0021] After the pipeline body is positioned and installed, this utility model can move the pressure detection mechanism into the pipeline body to perform pressure detection on the inner wall of the pipeline body. During the detection process, it can move to perform pressure testing on various areas of the pipeline body, thereby improving the accuracy of the pipeline body in actual use.

[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Example 1

[0034] like Figure 1-7 The detection device shown includes a base 1, which provides basic support for the entire device. A positioning ring 2 is fixedly installed on the top of the base 1. The positioning ring 2 is annular, and its inner diameter is adapted to the outer diameter of the pipe body 3 to be detected. The pipe body 3 is clamped onto the positioning ring 2 to achieve the initial positioning of the pipe body 3.

[0035] A moving mechanism is also installed on the top of the base 1. The moving mechanism includes two mounting rods 4 symmetrically fixedly installed on the top of the base 1. The mounting rods 4 are cylindrical and perpendicular to the surface of the base 1. Support screws 5 are fixedly installed at the top of the mounting rods 4, and the support screws 5 are also perpendicular to the surface of the base 1. The same connecting frame 6 located above the pipe body 3 is sleeved on the two support screws 5. The connecting frame 6 is a rectangular frame structure and can move longitudinally along the support screws 5. Two mounting boxes 8 are symmetrically fixedly installed on the connecting frame 6. The mounting boxes 8 are cuboid in shape and hollow inside.

[0036] The mounting box 8 houses a power assembly. The power assembly includes a first drive motor 9 fixedly mounted within the mounting box 8. The output shaft of the first drive motor 9 extends above the connecting frame 6 and is fixedly fitted with a drive gear 10. It also includes a threaded ring 7 that passes through and is rotatably connected to the connecting frame 6. A support screw 5 passes through the corresponding threaded ring 7 and is threadedly connected to the inner wall of the threaded ring 7. A driven gear 11, located above the connecting frame 6, is fixedly fitted on the threaded ring 7. The drive gear 10 meshes with the driven gear 11. When the first drive motor 9 is started, its output shaft drives the drive gear 10 to rotate. Through meshing with the driven gear 11, this drives the threaded ring 7 to rotate. Because the threaded ring 7 is threadedly connected to the support screw 5, the connecting frame 6 moves longitudinally along the two support screws 5 under the action of the threaded transmission.

[0037] Support rods 12 are fixedly installed at the bottom of the mounting box 8. The support rods 12 are cylindrical, and their bottom ends are connected to the pressure testing mechanism. The pressure testing mechanism includes connecting plates 13 fixedly installed at the bottom ends of the two support rods 12. The connecting plates 13 are rectangular flat plates. A conveying pipe 17, a cylindrical pipe, is fixedly installed through the connecting plates 13. A first support mesh ring 14 and a second support mesh ring 15 located within the first support mesh ring 14 are fixedly installed at the bottom of the connecting plates 13. Both the first and second support mesh rings 14 and 15 are annular mesh structures, and their bottoms are fixedly connected to the top of a base plate 16. The base plate 16 is a circular flat plate and is fixedly connected to the bottom end of the conveying pipe 17. Multiple flow holes are evenly spaced on the inner wall of the delivery pipe 17. A corrugated hose 27 is fixedly installed on the top of the base plate 16. The top of the corrugated hose 27 is fixedly connected to the bottom of the connecting plate 13. Hydraulic oil flows into the closed space formed by the connecting plate 13, the base plate 16 and the corrugated hose 27 through the multiple flow holes on the delivery pipe 17, expanding the corrugated hose 27 and squeezing the inner wall of the pipe body 3 to achieve pressure testing.

[0038] The transmission mechanism is mounted on the top of the connecting plate 13 and connected to the conveying pipe 17. The transmission mechanism includes a hydraulic tank 18 fixedly mounted on the top of the connecting plate 13, which is hollow and filled with hydraulic oil. An installation pipe is fixedly mounted on the bottom inner wall of the hydraulic tank 18, with its bottom end extending into the conveying pipe 17 and fixedly connected to the inner wall of the conveying pipe 17. A pushing assembly is mounted on the top of the hydraulic tank 18. The pushing assembly includes a second drive motor 19 fixedly mounted on the top of the hydraulic tank 18. A transmission screw 20 is fixedly mounted on the output shaft of the second drive motor 19. A transmission frame 22 is sleeved on the transmission screw 20, and a transmission nut 21 is fixedly mounted on the top of the transmission frame 22. The transmission screw 20 passes through the transmission nut 21 and is threadedly connected to it. A connecting cover 24 is fixedly installed at equal intervals on the top of the push plate 25. The connecting cover 24 is a cylindrical hollow structure, and a pressure sensor 26 is fixedly installed on its bottom inner wall. The top of the connecting cover 24 penetrates the top inner wall of the hydraulic tank 18 and extends to the top of the hydraulic tank 18. A transmission rod 23 is slidably connected inside the connecting cover 24. The top end of the transmission rod 23 extends to the top of the connecting cover 24 and is fixedly connected to the bottom of the transmission frame 22. The second drive motor 19 is started, and its output shaft drives the transmission screw 20 to rotate. Through the threaded transmission with the transmission nut 21, the transmission frame 22 is driven to move downward, which in turn drives multiple transmission rods 23 to move downward. Through the connecting cover 24, the push plate 25 is pushed downward, pushing the hydraulic oil in the hydraulic tank 18 into the delivery pipe 17. When the transmission rod 23 drives the connecting cover 24, it presses the pressure sensor 26. The pressure sensor 26 is connected to an external display wirelessly and transmits the detected pressure data to the display screen.

[0039] Specifically, the signal output terminal of the pressure sensor 26 is electrically connected to a miniature wireless transmission module, preferably a module using ZigBee, LoRa, or Wi-Fi protocols. This transmission module is fixedly installed inside the connecting cover 24. Correspondingly, a wireless receiving terminal and an external display are provided externally. The wireless receiving terminal is used to receive the pressure data signal emitted by the pressure sensor 26 and transmit it to the external display for real-time display. The external display not only displays the real-time pressure value but can also plot the pressure-time change curve. Based on the displayed pressure data, the operator can control the speed or start / stop of the second drive motor 19, i.e., control the downward pressure speed and stroke of the transmission screw 20, to regulate the amount of hydraulic oil pushed by the push plate 25, thereby achieving closed-loop control of the test pressure inside the pipeline. When the pressure curve experiences an abnormally sharp drop, it can be determined that there is a leak or insufficient strength defect in the inner wall of the pipeline at the current detection location.

[0040] In this process, the pressure value detected by pressure sensor 26 is precisely the force (F) pushing push plate 25. According to the hydraulic principle (P = F / A, where A is the cross-sectional area of ​​push plate 25), this force is directly proportional to the pressure (P) generated by the hydraulic oil. Therefore, monitoring this force is equivalent to indirectly monitoring the test pressure applied to the inner wall of the pipe.

[0041] Meanwhile, in order to solve the potential signal shielding problem inside the metal pipe, a wireless signal repeater is installed on the base 1. The repeater establishes a communication connection with the miniature wireless transmission module and the external receiving terminal to ensure stable data transmission.

[0042] This application can be used in the field of pipeline inspection technology, or in other fields applicable to this application.

[0043] Example 2

[0044] refer to Figures 1-3 An improvement upon Embodiment 1: A municipal pipeline inspection device, applied in the field of pipeline inspection technology, comprises multiple support boxes 28 fixedly installed at equal intervals on the top of a base 1. Each support box 28 is rectangular in shape and hollow inside. A movable plate 29, a rectangular flat plate, is slidably connected inside the support box 28, with an adjusting nut 31 fixedly installed on one side. The top of the movable plate 29 extends above the support box 28 and is fixedly installed with a clamping plate 32, an arc-shaped plate used to clamp and position the pipeline body 3. An adjusting screw 30 is rotatably connected to the inner wall of one side of the support box 28. One end of the adjusting screw 30 passes through the movable plate 29, the adjusting nut 31, and the inner wall of the other side of the support box 28, extending to the outer side of the support box 28. The adjusting screw 30 is threadedly connected to the adjusting nut 31. Rotating the adjusting screw 30 causes the moving plate 29 to move laterally through the threaded transmission with the adjusting nut 31, so that the clamping plate 32 moves closer to the pipe body 3 until it clamps and positions the pipe body 3 to prevent the pipe body 3 being tested from shifting.

[0045] During operation, the pipe body 3 to be inspected is clamped onto the positioning ring 2 fixedly installed on the top of the base 1 to initially determine the position of the pipe. The adjusting screw 30 is rotated. Since the adjusting screw 30 is threadedly connected to the adjusting nut 31 fixed on the moving plate 29, the moving plate 29 will slide in the support box 28 under the action of thread transmission. The moving plate 29 drives the clamping plate 32 fixedly installed on the top to move closer to the pipe body 3 until the clamping plate 32 is in close contact with the pipe body 3, so as to achieve a stable clamping and positioning of the pipe body 3 and prevent the pipe from shifting during the inspection process.

[0046] Two first drive motors 9 are started respectively. The output shaft of the first drive motor 9 drives the fixed set of drive gear 10 to rotate. When the drive gear 10 rotates, it drives the driven gear 11 to rotate, which in turn causes the threaded ring 7 to rotate. At this time, under the threaded transmission with the support screw 5, the connecting frame 6 will move longitudinally along the two support screws 5. The longitudinal movement of the connecting frame 6 will drive the pressure testing mechanism to move synchronously. After the pressure testing mechanism is moved to the corresponding position where the pipeline body 3 needs to be tested, the second drive motor 19 is started. The output shaft of the second drive motor 19 drives the transmission screw 20 to rotate. When the transmission screw 20 rotates, under the threaded transmission with the transmission nut 21, the transmission frame 22 will move downward. The multiple transmission rods 23 fixedly connected to the bottom of the transmission frame 22 move downward. The transmission rod 23 extends to the top of the connecting cover 24 and slides inside the connecting cover 24. When the transmission rod 23 moves downward, it pushes the push plate 25, which is fixed inside the hydraulic tank 18 and is tightly slidably connected to the inner wall of the hydraulic tank 18, downward through the connecting cover 24. The downward movement of the push plate 25 pushes the hydraulic oil in the hydraulic tank 18. The hydraulic oil flows into the delivery pipe 17 through the installation pipe fixedly installed on the bottom inner wall of the hydraulic tank 18, and then flows into the closed space surrounded by the connecting plate 13, the bottom plate 16 and the corrugated hose 27 through multiple flow holes equally spaced on the inner wall of the delivery pipe 17. The hydraulic oil expands the corrugated hose 27, causing the corrugated hose 27 to expand outward and squeeze the inner wall of the pipe body 3, thereby realizing the pressure test of the inner wall of the pipe body 3.

[0047] During the process of transmission rod 23 driving the connecting cover 24 and pushing the push plate 25, transmission rod 23 will press the pressure sensor 26. After being subjected to pressure, the pressure sensor 26 will detect the pressure. The pressure sensor 26 is connected to an external display wirelessly and transmits the detected pressure data to the display screen in real time. The operator can accurately control the pressure value to be detected by observing the pressure data on the display screen and judge the quality and stability of the pipeline body 3 based on the pressure change.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
