Description

Technical Field

[0001] This application relates to the field of sewage pipeline inspection technology, specifically a sewage pipeline anti-seepage inspection device. Background Technology

[0002] Sewage drainage pipes are widely used in daily life and engineering construction. Due to differences in materials and working conditions, their connection methods mainly include welding, hot-melt fusion, flange connections, clamp-tape connections, and rubber sleeve connections. However, all these connection methods carry the risk of leakage: welding and hot-melt connections are prone to gaps due to improper temperature control or insufficient welding; flange connections may experience aging of gaskets and loosening of bolts; clamp-tape connections suffer from tape aging and insufficient clamp tightening; and rubber sleeve connections may lead to sewage leakage due to sleeve wear and poor sealing at the joints.

[0003] Existing testing devices often employ a single-specification clamping structure or manually adjustable clamping method when fixing sewage pipes, making it difficult to adapt to sewage pipes of different diameters and connection processes. If the clamping is too loose, the sewage pipe may shift during testing, affecting accuracy; if the clamping is too tight, it may damage the pipe. Especially after the connection process is completed, the inability to quickly and accurately test the sealing of the connection points means that potential leaks may be masked by subsequent construction, increasing rework costs and environmental pollution risks. Therefore, this paper proposes a sewage pipe seepage prevention testing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sewage pipe seepage detection device that avoids displacement of the sewage pipe body due to excessively loose clamping, which would affect the accuracy of the detection, and also prevents damage to the sewage pipe body due to excessively tight clamping, thus greatly improving the applicability and reliability of the detection.

[0005] To achieve the above objectives, this application provides the following technical solution: a sewage pipe seepage prevention detection device, comprising a base, a waterproof pad, and a sewage pipe body. The waterproof pad is disposed on the upper end of the base, and the sewage pipe body is disposed on the upper end of the waterproof pad. A dual-axis motor is fixedly connected inside the base. Threaded posts are fixedly connected to both ends of the output shaft of the dual-axis motor. A transversely open U-shaped plate is provided at the far end of each set of threaded posts. Threaded holes are provided on the lower surface of each set of transversely open U-shaped plates. The threaded posts are threadedly connected to the transversely open U-shaped plates through the threaded holes. Both sets of transverse side-opening U-shaped plates have grooves on their upper surfaces near the top. A pressure sensor and a spring are fixedly connected inside the grooves. Movable rods are movably connected to the surfaces near the grooves of both sets of plates. A pressure rod is fixedly connected to the far end of each of the movable rods. The spring is sleeved on the surface of the pressure sensor and the pressure rod. The end of the spring near the pressure rod is fixedly connected to the end of the movable rod near the groove. A limit plate is fixedly connected to the near end of each of the movable rods. The pressure sensor is used to sense the pressure of the limit plate on the sewage pipe body, realizing adaptive limit detection of the sewage pipe body.

[0006] The above-described solution, through the coordination of a dual-axis motor, threaded column, transversely open U-shaped plate, pressure sensor, and spring, achieves adaptive limit detection of the sewage pipe body. Compared to traditional single-specification or manually adjustable clamping methods, this solution can automatically adapt to sewage pipes of different diameters, avoiding pipe displacement during detection due to excessively loose clamping, which affects accuracy, and also preventing damage to the pipe due to excessively tight clamping, thus improving the versatility and reliability of the detection.

[0007] Furthermore, a slider is fixedly connected to the surface of the transversely side-opening U-shaped plate near the dual-axis motor, and a groove is provided inside the base, with the slider movably connected inside the groove.

[0008] Through the above solution, the slider on the transversely opening U-shaped plate cooperates with the sliding groove inside the base, providing precise guidance and stable support for the movement of the transversely opening U-shaped plate driven by the threaded column. This ensures that the transversely opening U-shaped plate maintains smooth operation and does not deviate as it approaches or moves away from the sewage pipe body, thereby further ensuring the accuracy of limiting the sewage pipe body and ensuring the stability of the pipe position during the detection process.

[0009] Furthermore, a support shell is fixedly connected to the upper surface of the base, the support shell is fixedly connected to the lower end of the waterproof pad, a drain pipe is connected to the lower end of the waterproof pad, the upper end of the drain pipe passes through the inside of the support shell, the lower end of the drain pipe passes through the right side of the support shell, and a solenoid valve is provided on the surface of the drain pipe.

[0010] The above design provides a stable mounting base for the waterproof gasket, ensuring it remains in place during testing and fully exerts its sealing function. The drain pipe connected to the lower end of the waterproof gasket works in conjunction with a solenoid valve. After testing, opening the solenoid valve allows for the rapid discharge of any residual wastewater from the gasket. This prevents wastewater from remaining inside the device, facilitating cleaning and preventing prolonged corrosion of the internal structure, thus extending the device's lifespan.

[0011] Furthermore, a support frame is fixedly connected to the upper surface of the base, and an electric push rod is fixedly connected to the lower surface of the upper end of the support frame. A sealing cover is provided at the lower end of the electric push rod, and the sealing cover is used to abut against the end of the sewage pipe body.

[0012] The above-described solution, combining the support frame with the electric actuator, enables precise control of the sealing cap's vertical movement. Compared to manual operation, the electric actuator provides more stable and accurate control over the sealing cap's displacement, allowing it to quickly and accurately abut against the end of the drain pipe body. This ensures reliable and consistent sealing performance, improves testing efficiency, and reduces the intensity and error of manual operation.

[0013] Furthermore, a water inlet pipe is provided on the upper surface of the sealing cover, and a flow valve is provided on the surface of the water inlet pipe. The water inlet pipe is used to inject water into the body of the sewage pipe.

[0014] Through the above solution, the water inlet pipe on the sealing cap, in conjunction with the flow valve, can flexibly adjust the flow rate of water injected into the sewage pipe body according to different testing needs. Whether it is a rapid water injection for preliminary testing or a slow water injection for fine testing, the flow valve can precisely control the flow, meeting diverse testing scenarios and providing reliable support for accurately judging the seepage prevention performance of the sewage pipe.

[0015] Furthermore, a controller is provided on the front side of the base. The controller is electrically connected to the dual-axis motor and the pressure sensor. The controller is used to control the rotation of the dual-axis motor based on the pressure data sensed by the pressure sensor.

[0016] Through the above scheme, the controller, dual-axis motor, and pressure sensor are electrically connected to form an automated control system. The pressure sensor senses the pressure of the limit plate on the sewage pipe body in real time and transmits the data to the controller. The controller automatically controls the rotation of the dual-axis motor according to the preset pressure value. This achieves intelligent adjustment of the sewage pipe limit process, eliminating the need for repeated manual adjustments, reducing human intervention, improving detection efficiency and accuracy, and also enhancing the automation level of the device.

[0017] Furthermore, a liquid level sensor is provided at the lower end of the sealing cover.

[0018] The liquid level sensor installed at the lower end of the sealing cap, as described above, can monitor the liquid level changes inside the sewage pipe in real time. During water injection testing, the liquid level data fed back by the sensor allows testing personnel to intuitively and accurately determine whether there is a leakage problem in the sewage pipe. If there is a leakage, the rate of liquid level rise or the final liquid level height will differ from the normal situation, thus providing important evidence for testing the anti-seepage performance of the sewage pipe and improving the reliability of the test results.

[0019] Furthermore, the waterproof gasket is made of nitrile rubber, which has good water resistance and sealing properties, and can effectively seal the lower end of the sewage pipe body.

[0020] The above solution utilizes nitrile rubber for the waterproof gasket, leveraging its excellent water resistance and sealing properties to effectively prevent wastewater from leaking from the lower end of the drain pipe into the base during testing. This protects the internal structure of the device from wastewater corrosion and maintains a clean testing environment. Simultaneously, the sealing gasket at the lower end of the sealing cap is made of a suitable material, allowing for sufficient compression to achieve a tight seal when in contact with the drain pipe, ensuring no leakage during testing and improving the accuracy and reliability of the test results.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This sewage pipe seepage detection device uses a dual-axis motor to drive a threaded column to rotate, which in turn moves a transversely open U-shaped plate. A threaded connection is achieved through threaded holes, allowing for flexible position adjustment based on the sewage pipe's diameter. A pressure sensor and spring within the groove, working in conjunction with a movable rod, pressure rod, and limiting plate, sense the pressure exerted by the limiting plate on the sewage pipe, enabling adaptive limit detection. Compared to single-specification clamping structures or manual adjustments, this device eliminates the need for frequent manual adjustments, quickly adapting to sewage pipes of different diameters. It avoids loose clamping that could cause pipe displacement and affect detection accuracy, while also preventing excessive clamping that could damage the pipe, significantly improving the applicability and reliability of the detection. The slider on the transversely open U-shaped plate engages with a groove inside the base, providing guidance and stable support for the plate's movement. This ensures the U-shaped plate remains stable during movement, preventing deviation and further guaranteeing accurate limiting of the sewage pipe. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4This embodiment of a sewage pipe seepage detection device includes a base 1, a waterproof pad 2, and a sewage pipe body 3. The waterproof pad 2 is disposed on the upper end of the base 1, and the sewage pipe body 3 is disposed on the upper end of the waterproof pad 2. A dual-axis motor 4 is fixedly connected inside the base 1. Threaded posts 5 are fixedly connected to both ends of the output shaft of the dual-axis motor 4. A transversely open U-shaped plate 6 is provided at the far end of each set of threaded posts 5. Threaded holes 7 are opened on the lower surface of each set of transversely open U-shaped plates 6. The threaded posts 5 are threadedly connected to the transversely open U-shaped plates 6 through the threaded holes 7. Grooves 8 are opened on the upper surface of each set of transversely open U-shaped plates 6. A pressure sensor 9 and a spring 1 are fixedly connected inside the groove 8. Two sets of grooves 8 are movably connected to movable rods 11 near their surfaces. Each set of movable rods 11 is fixedly connected to a pressure rod 12 at its far end. A spring 10 is sleeved on the surface of the pressure sensor 9 and the pressure rod 12. The end of the spring 10 near the pressure rod 12 is fixedly connected to the end of the movable rod 11 near the groove 8. Each set of movable rods 11 is fixedly connected to a limit plate 13 at its far end. The pressure sensor 9 senses the pressure of the limit plate 13 on the drain pipe body 3, achieving adaptive limit detection of the drain pipe body 3. Through the cooperation of the dual-axis motor 4, threaded column 5, transversely open U-shaped plate 6, pressure sensor 9, and spring 10, adaptive limit detection of the drain pipe body 3 is achieved. Compared to traditional single-specification or manually adjustable clamping methods, this method can automatically adapt to drain pipes of different diameters, avoiding pipe displacement during detection due to excessively loose clamping, and preventing damage to the pipe due to excessively tight clamping, thus improving the versatility and reliability of the detection.

[0032] Please see Figure 1 , Figure 2 and Figure 5A slider 14 is fixedly connected to one end of the transversely open U-shaped plate 6 near the dual-axis motor 4. A groove 15 is provided inside the base 1, and the slider 14 is movably connected inside the groove 15. A support shell 16 is fixedly connected to the upper surface of the base 1. The support shell 16 is fixedly connected to the lower end of the waterproof pad 2. A drain pipe 17 is connected to the lower end of the waterproof pad 2. The upper end of the drain pipe 17 passes through the inside of the support shell 16, and the lower end of the drain pipe 17 passes through the right side of the support shell 16. A solenoid valve 18 is provided on the surface of the drain pipe 17. A support frame 19 is fixedly connected to the upper surface of the base 1. An electric push rod 20 is fixedly connected to the lower surface of the upper end of the support frame 19. A sealing cover 21 is provided at the lower end of the electric push rod 20. The sealing cover 21 is used to abut against the end of the sewage pipe body 3. The slider 14 on the transversely open U-shaped plate 6 cooperates with the groove 15 inside the base 1, providing precise guidance and stable support for the movement of the transversely open U-shaped plate 6 driven by the threaded column 5. The U-shaped plate 6 with the lateral opening maintains stable operation as it approaches or moves away from the sewage pipe body 3, preventing any deviation. This further ensures the accuracy of the positioning of the sewage pipe body 3 and guarantees the stability of the pipe position during testing. The support shell 16 provides a stable installation base for the waterproof pad 2, ensuring that the waterproof pad 2 remains in a fixed position during testing and fully exerts its sealing function. The drain pipe 17 connected to the lower end of the waterproof pad 2 works in conjunction with the solenoid valve 18. After testing, the residual sewage on the waterproof pad 2 can be quickly discharged by opening the solenoid valve 18. This prevents sewage from remaining inside the device, facilitating cleaning and preventing long-term sewage residue from corroding the internal structure of the device, thus extending its service life. The support frame 19, combined with the electric push rod 20, can precisely control the up-and-down movement of the sealing cover 21. Compared to manual operation, the electric push rod 20 can achieve more stable and precise displacement control of the sealing cover 21, allowing the sealing cover 21 to quickly and accurately abut against the end of the sewage pipe body 3, ensuring the reliability and consistency of the sealing effect, improving testing efficiency, and reducing the intensity and error of manual operation.

[0033] Please see Figure 1 , Figure 2 and Figure 3A water inlet pipe 22 is installed on the upper surface of the sealing cover 21, and a flow valve 25 is installed on the surface of the water inlet pipe 22. The water inlet pipe 22 is used to inject water into the sewage pipe body 3. A controller 24 is installed on the front side of the base 1. The controller 24 is electrically connected to the dual-axis motor 4 and the pressure sensor 9. The controller 24 is used to control the rotation of the dual-axis motor 4 according to the pressure data sensed by the pressure sensor 9. A liquid level sensor 23 is installed at the lower end of the sealing cover 21. The waterproof gasket 2 is made of nitrile rubber, which has good water resistance and sealing performance, and can effectively seal the lower end of the sewage pipe body 3. The water inlet pipe 22 on the sealing cover 21 works with the flow valve 25 to flexibly adjust the flow rate of water injected into the sewage pipe body 3 according to different testing needs. Whether it is necessary to inject water quickly for preliminary testing or to inject water slowly for fine testing, it can be precisely controlled by the flow valve 25 to meet diverse testing scenarios and provide reliable support for accurately judging the anti-seepage performance of the sewage pipe. The controller 24 is electrically connected to the dual-axis motor 4 and the pressure sensor 9, forming an automated control system. The pressure sensor 9 senses the pressure of the limit plate 13 on the sewage pipe body 3 in real time and transmits the data to the controller 24. The controller 24 automatically controls the rotation of the dual-axis motor 4 according to the preset pressure value. This realizes intelligent adjustment of the sewage pipe limit process, eliminating the need for repeated manual adjustments, reducing human intervention, improving detection efficiency and accuracy, and also enhancing the automation level of the device. The liquid level sensor 23 installed at the lower end of the sealing cover 21 can monitor the changes in the liquid level inside the sewage pipe body 3 in real time. During the water injection test, the liquid level data fed back by the liquid level sensor 23 allows the tester to intuitively and accurately determine whether there is a leakage problem in the sewage pipe. If there is a leakage in the sewage pipe, the rate of liquid level rise or the final liquid level height will differ from the normal situation, thus providing an important basis for the sewage pipe seepage prevention performance test and improving the reliability of the test results. The waterproof gasket 2 is made of nitrile rubber, which, with its good water resistance and sealing properties, effectively prevents sewage from leaking from the lower end of the sewage pipe body 3 to the base 1 during the test, protecting the internal structure of the device from sewage corrosion and maintaining the cleanliness of the test environment. Meanwhile, the sealing gasket at the lower end of the sealing cap 21 is made of a suitable material, which can be fully compressed to achieve a tight seal when it comes into contact with the sewage pipe body 3, ensuring no leakage during the testing process and improving the accuracy and reliability of the test results.

[0034] In this embodiment, the threaded column 5 is driven to rotate by the dual-axis motor 4, which in turn moves the transversely open U-shaped plate 6. A threaded connection is achieved through the threaded hole 7, allowing for flexible adjustment of its position according to the diameter of the sewage pipe body 3. The pressure sensor 9 and spring 10 within the groove 8, in conjunction with the movable rod 11, pressure rod 12, and limiting plate 13, can sense the pressure of the limiting plate 13 on the sewage pipe body 3, achieving adaptive limit detection. Compared to a single-specification clamping structure or manual adjustment, this device eliminates the need for frequent manual adjustments, quickly adapting to sewage pipe bodies 3 of different diameters. It avoids the sewage pipe body 3 shifting due to excessively loose clamping, which affects detection accuracy, and also prevents damage to the sewage pipe body 3 due to excessively tight clamping, greatly improving the applicability and reliability of the detection. The slider 14 on the transversely open U-shaped plate 6 cooperates with the sliding groove 15 inside the base 1, providing guidance and stable support for the movement of the transversely open U-shaped plate 6. This ensures that the transversely open U-shaped plate 6 remains stable during movement and does not shift, further guaranteeing the accuracy of the limit on the sewage pipe body 3.

[0035] The working principle of the above embodiment is as follows: The sewage pipe body 3 is placed on the waterproof pad 2 at the upper end of the base 1. The dual-axis motor 4 is started, and its output shaft drives the threaded posts 5 at both ends to rotate. Since the threaded posts 5 are threadedly connected to the transverse side opening U-shaped plate 6 through the threaded hole 7, and the slider 14 on the transverse side opening U-shaped plate 6 slides and is guided in the sliding groove 15 of the base 1, the transverse side opening U-shaped plate 6 will move along the threaded posts 5 toward the sewage pipe body 3. When the limiting plate 13 contacts the sewage pipe body 3, its continued movement will compress the spring 10 in the groove 8. At the same time, the pressure sensor 9 senses the pressure of the limiting plate 13 on the sewage pipe body 3 and transmits the data to the controller 24. The controller 24 controls the rotation of the dual-axis motor 4 based on pressure data. When the pressure reaches a preset value, the dual-axis motor 4 stops, achieving adaptive limit control of the sewage pipe body 3 and ensuring the stability of the sewage pipe body 3 during the detection process. The support frame 19 on the base 1 supports the electric push rod 20. After the electric push rod 20 is activated, it drives the lower sealing cover 21 to move downward until the sealing cover 21 abuts against the end of the sewage pipe body 3. The sealing cover 21 fits tightly against the sewage pipe body 3, achieving a seal on the upper end of the sewage pipe body 3. Water is injected into the sewage pipe body 3 through the water inlet pipe 22 on the upper surface of the sealing cover 21, and the water injection flow rate is controlled by the flow valve 25 on the surface of the water inlet pipe 22. The liquid level sensor 23 at the lower end of the sealing cover 21 monitors the liquid level inside the sewage pipe body 3 in real time. If there is leakage in the drain pipe, the liquid level will rise at a different rate than normal, or the liquid level may not reach the preset height. This will help determine the anti-seepage performance of the drain pipe body 3. After the test is completed, the solenoid valve 18 on the surface of the drain pipe 17 is opened. Since the lower end of the waterproof pad 2 is connected to the drain pipe 17 and the waterproof pad 2 is fixedly supported by the support shell 16, the residual sewage on the waterproof pad 2 will be discharged through the drain pipe 17, which will facilitate the cleaning of the device and its next use. The waterproof pad 2 is made of nitrile rubber, which has good water resistance and sealing properties, effectively preventing sewage from leaking from the lower end of the drain pipe body 3 to the base 1.
