Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology and provides a pipeline cleaning and detection system. Background Technology

[0002] Currently, the water supply pipelines of high-speed trains use copper pipes connected by brazing. Under high-temperature brazing conditions (the flame temperature can reach 680℃), a black copper oxide film will form on the inner wall of the copper pipes. If this copper oxide film is not cleaned from the inner wall of the copper pipes, this impurity will enter the water-using equipment through the water supply pipeline during the high-speed train's commissioning process, polluting the water source. Therefore, after the copper pipes are brazed, it is necessary to use a copper pipe cleaning device to flush the inner wall of the pipelines to remove the copper oxide impurities and ensure the cleanliness of the pipeline interior.

[0003] However, existing copper pipe cleaning devices cannot ensure that the inner wall of the copper pipe is thoroughly cleaned after a single rinse. Furthermore, without a water quality monitoring device after multiple rinses, it is impossible to determine when to stop cleaning. Therefore, existing copper pipe cleaning devices suffer from low cleaning efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly.

[0028] like Figures 1 to 5 As shown, this utility model provides a pipeline cleaning and testing system. The pipeline cleaning and testing system includes: a water tank 101, a water quality testing device, and a pumping device 300.

[0029] The water tank 101 has an outlet and a first return water outlet, which are respectively connected to the pipeline to be cleaned. A water quality detection device is located between the first return water outlet and the pipeline to be cleaned to detect the water quality of the cleaning return water. A pumping device 300 is located between the outlet and the pipeline to be cleaned and is connected to the water quality detection device to determine the pipeline cleaning status based on the water quality of the cleaning return water.

[0030] Specifically, the water tank 101 stores clean water for cleaning the pipes. Water is discharged to the pipes to be cleaned through the outlet. After cleaning the pipes, the return water flows back to the water tank 101 through the first return water outlet, realizing the recycling of cleaning water.

[0031] A water quality testing device is installed on the pipeline between the first return water inlet and the pipeline to be cleaned. The device tests the water quality of the return water to determine the cleanliness of the pipeline. Understandably, if the return water quality is poor, it indicates that the pipeline is not clean enough and cleaning needs to continue; if the return water quality is good, it indicates that the pipeline is clean enough and cleaning can be stopped.

[0032] A pumping device 300 is installed between the outlet and the pipeline to be cleaned, used to pump clean water from the water tank 101 into the pipeline for cleaning. The on / off state of the pumping device 300 depends on the quality of the return water, and can be controlled manually or by an electronic control device. When using manual judgment, the reading of the water quality detection device is observed to determine whether cleaning needs to continue; when using an electronic control device, the water quality detection device detects the degree of water cleanliness and converts it into an electrical signal to automatically control the pumping device 300.

[0033] Preferably, the pumping device 300 can be a water pump.

[0034] This utility model provides a pipeline cleaning and testing system, comprising: a water tank 101, a water quality testing device, and a pumping device 300. The water tank 101 has an outlet and a first return water outlet, which are respectively connected to the pipeline to be cleaned. The water quality testing device is located between the first return water outlet and the pipeline to be cleaned, and is used to detect the water quality of the cleaning return water. The pumping device 300 is located between the outlet and the pipeline to be cleaned, and is signal-connected to the water quality testing device, used to determine the pipeline cleaning status based on the water quality of the cleaning return water. This pipeline cleaning and testing system achieves the recycling of cleaning water through the outlet and the first return water outlet. By setting up a water quality testing device to detect the quality of the return water, it determines whether cleaning needs to continue, thereby controlling the on / off state of the pumping device 300 to determine when cleaning can be stopped, thus improving cleaning efficiency.

[0035] In one embodiment of this utility model, the water quality detection device includes a turbidity sensor 200, which is used to detect the concentration of suspended particulate matter in the return water liquid. Turbidity reflects the clarity of water or other liquids. Turbidity refers to the phenomenon that the light transmittance decreases due to the scattering and absorption of light by suspended particles (such as silt, algae, organic matter, microorganisms, etc.) in the water. The turbidity sensor 200 is an instrument used to measure the concentration of suspended particulate matter (i.e., turbidity) in a liquid.

[0036] In one embodiment of this utility model, the turbidity sensor 200 includes a liquid container, an infrared emitting tube, and an infrared receiving tube. The liquid container is located between the first return water inlet and the pipeline to be cleaned; the infrared emitting tube is located on one side of the liquid container; and the infrared receiving tube is located on the other side of the liquid container. The infrared receiving tube receives infrared light transmitted through the return water in the liquid container and converts the light intensity of the infrared light into current intensity to determine the degree of turbidity of the return water. Specifically, the liquid container stores the return water. The infrared emitting tube irradiates the return water in the liquid container, and the infrared light transmitted through the return water is received by the infrared receiving tube. When infrared light passes through the water to be tested in the liquid container, the infrared receiving tube converts the transmitted light intensity into a corresponding current magnitude. More transmitted light results in a larger current, and vice versa. Simultaneously, the degree of turbidity of the water affects the amount of light transmitted; the more turbid the water, the less light transmitted; conversely, the cleaner the water, the more light transmitted. Finally, the degree of turbidity of the effluent is assessed by measuring the current at the receiving end of the turbidity sensor 200 (i.e., the infrared receiving tube). Understandably, a current threshold can be preset in the controller. When the detected current is greater than the preset current threshold, it indicates that the return water is relatively clear and the pipeline has been cleaned. The pumping device 300 is then turned off, and the cleaning is automatically stopped. Conversely, when the current is less than or equal to the preset current threshold, the pumping device 300 is turned on to continue cleaning the pipeline.

[0037] In one embodiment of this utility model, the water quality testing device further includes a water storage tank 201, which is disposed between the liquid container and the pipeline to be cleaned. In this embodiment, by setting up the water storage tank 201 upstream of the liquid container, a certain amount of return water is stored as a buffer.

[0038] In one embodiment of this utility model, the water tank 101 further has a second return water inlet, which is connected to the pipeline to be cleaned. The pipeline cleaning and detection system also includes a filtration device disposed between the second return water inlet and the pipeline to be cleaned. Specifically, the water tank 101 further has a second return water inlet, and a filtration device is installed between the return water inlet and the pipeline to be cleaned. The return water is filtered by the filtration device, thereby improving the quality of the circulating water and increasing the pipeline cleaning efficiency.

[0039] In one embodiment of this utility model, the filtration device includes a multi-stage pre-filter 400. The multi-stage pre-filter 400 is connected in series between the second return water inlet and the pipeline to be cleaned, thereby filtering the return water sequentially through the multi-stage pre-filter 400, thus improving the filtration effect. Specifically, the multi-stage pre-filter 400 uses a PP filter element.

[0040] In one embodiment of this utility model, the pipeline cleaning and testing system further includes: a return water testing pipeline 500, a first valve body 501, a second valve body 502, a first return water pipe 503, and a second return water pipe 504. The first end of the return water testing pipeline 500 is connected to the pipeline to be cleaned, its second end is connected to a filtration device, and its third end is connected to a water quality testing device. The first valve body 501 is disposed on the return water testing pipeline 500 and near its second end. The second valve body 502 is disposed on the return water testing pipeline 500 and near its third end. One end of the first return water pipe 503 is connected to the outlet of the water quality testing device, and its other end is connected to a water tank 101. One end of the second return water pipe 504 is connected to the outlet of the filtration device, and its other end is connected to the water tank 101.

[0041] Specifically, the first end of the return water detection pipe 500 is connected to the pipe to be cleaned to receive return water. Its second end leads to a filtration device for filtering the return water, which then flows back to the water tank 101 through the second return water pipe 504. The third end of the return water detection pipe 500 leads to a water quality testing device to test the water quality. The tested water then flows back to the water tank 101 through the first return water pipe 503. A first valve body 501 and a second valve body 502 are respectively installed near the second and third ends to control water flow. When water quality testing is not required, the second valve body 502 is closed, and all return water passes through the filtration device before flowing back to the water tank 101.

[0042] In one embodiment of this utility model, the first end of the return water detection pipeline 500 has a first interface 505 and a second interface 506, and a third valve body 507 is respectively provided on the first interface 505 and the second interface 506. Specifically, the return water detection pipeline 500 has two return water interfaces, namely the first interface 505 and the second interface 506, and a valve body is respectively provided on the first interface 505 and the second interface 506 to control whether water flows through.

[0043] In one embodiment of this utility model, the pipeline cleaning and detection system further includes: a water outlet pipe 600, a fourth valve body 601, and a pressure sensor 602. The water outlet pipe 600 is sequentially connected to a water outlet, a pumping device 300, and the pipeline to be cleaned, and a third interface 603 is provided at the first end of the water outlet pipe 600 near the pipeline to be cleaned; the fourth valve body 601 is disposed on the water outlet pipe 600 and disposed near the third interface 603; the pressure sensor 602 is disposed on the water outlet pipe 600 and disposed near the third interface 603. Specifically, the outlet pipe 600 is sequentially connected to the outlet of the water tank 101, the pumping device 300, and the pipeline to be cleaned. A third interface 603 is provided at the end of the outlet pipe 600 for connection to the pipeline to be cleaned. A fourth valve body 601 is provided on the third interface 603 to control the flow of water. A pressure sensor 602 is provided near the third interface 603 to display the water pressure. In conjunction with the fourth valve body 601 and the pumping device 300, the outlet water pressure can be adjusted to ensure efficient pipeline cleaning. Preferably, the pressure of the outlet water maintained by the fourth valve body 601 and the pumping device 300 can meet the pipeline water pressure holding test requirements of less than 500 kPa.

[0044] In one embodiment of this utility model, the pipeline cleaning and inspection system further includes a housing 100 and a traveling device 700. The housing 100 has multiple partitions, dividing the housing 100 into a water tank 101, a power supply box 102, and a control box 103; the traveling device 700 is mounted on the housing 100. The housing 100 is divided into multiple areas by the partitions, including at least a water tank 101, a power supply box 102, and a control box 103, separating the water and electrical areas to improve safety. The traveling device 700 is located at the bottom of the housing 100, enabling the pipeline cleaning and inspection system to move.

The drive wheels are powered by a motor and cooperate with the traveling wheels to move the pipeline cleaning and inspection system.
