Technical Field
[0001] This invention belongs to the field of pipeline performance testing technology, specifically relating to a pipeline water tightness testing system and its testing method. Background Technology
[0002] Underground pipelines are an important part of modern urban infrastructure, mainly including pipelines for water supply, drainage, gas, heating, electricity, communications, radio and television, and industry, as well as their ancillary facilities. They bear the important mission of delivering water, electricity, gas, and signals to every corner of the city, while also transporting wastewater and waste generated by the city's operation to designated locations.
[0003] Drainage pipes are responsible for transporting sewage over long distances and must maintain sufficient airtightness to prevent sewage leakage and environmental pollution. After on-site pipeline construction is completed, a water tightness test is usually conducted to check the pipe's airtightness. However, currently, there is no suitable equipment for this test.
[0004] At present, the main method for detection is to manually observe water level and add water manually. Although this method is widely used, it also has the following drawbacks: the accuracy cannot be guaranteed by manually observing water level changes and adding water manually; and the efficiency and error rate are high by manually recording data. Summary of the Invention
[0005] The purpose of this invention is to provide a pipeline water tightness detection system and its detection method to solve the technical problems of large errors and low efficiency in manual observation, manual water addition, and manual recording.
[0006] To address the aforementioned technical problems, this invention provides a pipeline water tightness detection system, comprising:

[0008] A water tank that supplies water to the pipeline, and a flow meter is installed below the water tank;
[0009] A recording system is provided, which is located on the side of the pole away from the fixed component, and the recording system includes a camera facing the observation scale;

[0014] Furthermore, to ensure measurement accuracy and efficiency, the recording system also includes:
[0015] The system includes a take-up reel assembly, a lighting lamp, a mounting block, and a counterweight. The lighting lamp and the camera are both mounted on the mounting block. A counterweight is located at the lower end of the mounting block and is placed inside the pipe. The upper end of the mounting block is connected to the cable of the take-up reel assembly, and the take-up reel of the take-up reel assembly is located on one side of the pipe.
[0016] Furthermore, the first fixing component includes: a first sleeve, which is sleeved on the upright, has a first mounting hole, a first fastening bolt fitted in the first mounting hole, and a support leg on one side of the first sleeve.
[0017] Furthermore, to facilitate the adjustment of the support leg angle, the support leg and the first sleeve are pivotally connected.
[0018] Furthermore, in order to increase the stability of the upright, the second fixing component is disposed above the first fixing component. The second component includes a second sleeve, which is sleeved on the upright, and a telescopic rod is pivotally connected to one side of the second sleeve.
[0019] Furthermore, to facilitate the length adjustment of the telescopic rod, the telescopic rod includes a fixed rod and an adjusting sleeve.

[0020] Furthermore, to facilitate the use of the take-up reel assembly, a support frame is provided below the rope between the take-up reel and the mounting block.
[0021] This invention also provides a method for detecting water tightness in pipelines, using the aforementioned pipeline water tightness detection system, comprising the following steps:
[0022] S1. Water is added to the pipe through the water tank. The flow meter on the water supply pipe below the water tank records the water volume and sends the water volume to the controller.
[0023] S2. Adjust the fixing components to ensure that the observation ruler on the pole is vertical and has a suitable water entry distance;

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] like Figure 1 The diagram shows the preferred embodiment of the present invention. The present invention provides a pipeline water tightness detection system, including: an observation ruler 1, a water tank 5, a recording system, and a controller 7. The observation ruler 1 is mounted on a pole 2 to record the water level in the pipeline. A fixing component is provided on one side of the pole 2. The pole 2, with the observation ruler 1 attached, is inserted into the water in the pipeline. The fixing component ensures the stability of the pole 2. The water tank 5 supplies water to the pipeline. A flow meter 51, which can be an ultrasonic flow meter, is installed below the water tank 5. The recording system is located on the side of the pole 2 away from the fixing component. The recording system includes a camera 61, which faces the observation ruler 1. Both the recording system and the flow meter 51 are electrically connected to the controller 7. The recording system captures the water level data on the observation ruler 1 in real time and transmits the water level data to the controller 7. The controller 7 adjusts the water level in the water tank 5 according to the water level data, monitors the water replenishment through the flow meter 51, and judges the water tightness performance of the pipeline based on the water level drop data and the water replenishment data. Figure 1 The pipe is formed by the eight walls of the pipe.
[0043] The upright pole 2 is equipped with a tilt sensor 21, which determines whether the upright pole 2 is vertical. If it is tilted, the upright pole 2 and the fixing components can be adjusted to keep the upright pole 2 vertical. The tilt sensor 21, the ultrasonic flow meter 51, and the camera system all have wireless transmission capabilities, which wirelessly transmit data to the controller 7 and receive instructions from the controller 7.
[0044] The fixing components include a first fixing component and a second fixing component. The first fixing component and the second fixing component are arranged on the same side of the upright 2. The first fixing component and the second fixing component cooperate to insert into the ground 9 to fix the upright 2, so that the upright 2 is suspended in the pipe, increasing the usability of the device.
[0045] The first fixing component includes: a first sleeve 31, which is sleeved on the upright 2. The first sleeve 31 has a first mounting hole, and a first fastening bolt 32 is fitted into the first mounting hole. A support leg 33 is provided on one side of the first sleeve 31. The support leg 33 and the first sleeve 31 are pivotally connected. The upright 2 is placed in the pipe, and the position of the upright 2 is roughly adjusted so that the water level in the pipe is slightly above the observation ruler 1. The water level is also within the measurement range of the observation ruler 1 as it drops. The position of the first sleeve 31 is adjusted and fastened to the upright 2 so that the bottom of the support leg 33 can be easily inserted into the ground.
[0046] The second fixing component is positioned above the first fixing component. After adjusting the first fixing component, the second fixing component is adjusted to keep the pole 2 vertical and stable. The second component includes a second sleeve 41, which is fitted onto the pole 2. A telescopic rod is pivotally connected to one side of the second sleeve 41. The telescopic rod includes a fixed rod 42 and an adjusting sleeve 43. One end of the fixed rod 42 is pivotally connected to the second sleeve 41, and the other end of the fixed rod 42 is inserted into the adjusting sleeve 43. A second mounting hole is provided at the end of the adjusting sleeve 43 near the fixed rod 42, and a second fastening bolt 44 is fitted into the second mounting hole. After adjusting the pole 2 to be vertical, the length of the telescopic rod is adjusted so that the lower end of the telescopic rod can be easily inserted into the ground to further fix the pole 2. The pole 2 is suspended and fixed above the pipeline by the first and second fixing components. The fixing components do not affect the observation of the observation ruler 1 and can maintain a good fixing effect, which is suitable for pipeline water level measurement.
[0047] The recording system also includes: a take-up reel assembly, an illumination lamp 64, a mounting block 65, and a counterweight 66. Both the illumination lamp 64 and the camera 61 are mounted on the mounting block 65. The illumination lamp 64 provides light to the observation scale 1, facilitating data capture by the camera 61 in low-light conditions. The counterweight 66 is located at the lower end of the mounting block 65 and is placed inside the pipe, supporting the camera 61 and ensuring its vertical position for optimal recording. The upper end of the mounting block 65 is connected to the cable 63 of the take-up reel assembly. The take-up reel 62 is located on one side of the pipe. A support frame 67 is located below the cable 63 between the take-up reel 62 and the mounting block 65. The height of the camera 61 can be easily adjusted using the take-up reel assembly. Both the camera 61 and the illumination lamp 64 must be waterproof.
[0048] like Figure 2 As shown, the present invention also provides a method for detecting water tightness in pipelines, which uses the above-mentioned pipeline water tightness detection system and includes the following steps:
[0049] S1. Water is added to the pipe through the water tank 5. The flow meter 51 on the water supply pipe below the water tank 5 records the water volume and sends the water volume to the controller 7.
[0050] S2. Adjust the fixing components so that the observation ruler 1 on the pole 2 is vertical and has a suitable water entry distance; specifically, it includes: S21. Adjust the position of the first sleeve 31 on the pole 2 so that the observation ruler 1 on the pole 2 has a suitable water entry distance. The suitable water entry distance means that when the pole 2 is placed in the pipe, the water level in the pipe is at a position slightly above the observation ruler 1, and the water level is within the measurement range of the observation ruler 1 during the descent process.
[0051] S22. Secure the first sleeve 31 to the upright 2 with the first fastening bolt 32, and insert the support leg 33 into the ground 9 on the outer periphery of the pipe;
[0052] S23. Adjust the upright rod 2 to be set vertically according to the tilt sensor;
[0053] S24. By extending and retracting the telescopic rod, the lower end of the telescopic rod can be inserted into the ground 9 on the outer periphery of the pipe, ensuring the verticality of the upright rod 2 while ensuring its stability.
[0054] S3. Place the recording system inside the pipe so that the camera 61 faces the observation scale 1, record the observation scale 1, and send the recorded data to the controller 7. Specifically, adjust the take-up reel 62 so that only the counterweight 66 and the camera 61 are submerged in the water.
[0055] S4, Controller 7 records the water level in the pipeline based on the recorded data, and controls the water tank 5 to replenish water to the pipeline according to the drop in water level;
[0056] S5. Determine the water tightness of the pipeline based on the water level drop data and water replenishment data.
[0057] In summary, the pipeline water tightness detection system and method of the present invention firstly involves setting up a fixing component to stably and vertically insert a pole into the pipeline water level. The water level is measured using a water level gauge, and the data is captured by a camera and sent to a controller to monitor the water level within the pipeline. The controller adjusts the water tank's discharge based on the pipeline water level, and the discharge volume is monitored by a flow meter and transmitted back to the controller. The pipeline's water tightness performance is determined based on the water level drop data and the water replenishment volume data. This improves the overall automation level of the system, exhibits good stability, and the detection method using this system offers high detection accuracy and efficiency.
