Description

Technical Field

[0001] This application relates to the field of sanitary testing technology, and more specifically, to a sanitary testing controller for a high-speed train water supply system. Background Technology

[0002] The sanitary monitoring controller for the water supply system of high-speed trains is an intelligent device that integrates water quality monitoring, data analysis, and disinfection control to ensure the sanitary safety of train water tanks, pipelines, and outlets. Its core functions include: real-time water quality monitoring, microbial risk early warning, dynamic disinfection control, and remote data management.

[0003] Traditional high-speed train water supply systems require the use of a sanitary monitoring controller connected to the water supply pipeline. The controller monitors water quality in real time via a detection module. However, the controller is frequently subjected to external vibrations when used on a high-speed train, which may cause leaks at the pipeline interfaces. If leaks are not detected in time, they will affect the normal water supply of the high-speed train and even waste water resources. However, the inlet and outlet pipe connections of the monitoring controller are usually located externally. When installed on the high-speed train, they are suspended or covered, making them difficult to observe with the naked eye and also inconvenient for detecting leaks.

[0004] In view of this, we propose a sanitary monitoring controller for the water supply system of high-speed trains. Utility Model Content

[0005] The purpose of this application is to provide a sanitary detection controller for the water supply system of a high-speed train, which can effectively solve the problem in the prior art that the connection end of the inlet and outlet water pipes for detection and control is usually set on the outside, and when installed with the high-speed train, it is suspended or covered, making it difficult to observe with the human eye and also inconvenient to detect water leakage.

[0006] This application provides a sanitary monitoring controller for a high-speed train water supply system, comprising:

[0007] A testing box, on one side of which a display and controller are fixedly installed;

[0009] The detection component is fixedly installed on the outside of the water pipe and is used to detect the water quality flowing through the inside of the water pipe;

[0010] The leak detection strip is located at the bottom of the two pipe joints and is arranged in a ring.

The arc-shaped support plate and the arc-shaped support plate are used to support the leak detection strip at the bottom of the pipe joint. An operation port is opened at the bottom of the end plate corresponding to the pipe joint.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) Since this application adopts a ring-shaped arrangement at the bottom of both, when a leak occurs, the leak signal can be collected in time and fed back for display and alarm.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This application discloses a sanitary testing controller for a high-speed train water supply system, including a testing box 1, a water pipe 2, a testing component 3, and a leakage detection strip 4. A display controller 11 is fixedly installed on one side of the testing box 1; the water pipe 2 is fixedly installed inside the testing box 1, and pipe joints 21 are fixedly installed at both ends of the water pipe 2 for connecting to the high-speed train water supply system; the testing component 3 is fixedly installed on the outside of the water pipe 2 for detecting the water quality flowing through the water pipe 2; the leakage detection strip 4 is located at the bottom of the two pipe joints 21 and is arranged in a ring; a back plate 13 is detachably installed on the back of the testing box 1, and pipe holes 14 are opened on the inner side of the back plate 13 corresponding to the pipe joints 21; a mounting bracket 15 for connecting to the high-speed train is fixedly installed on the outside of the testing box 1; and a communication interface 12 is also provided on the outside of the testing box 1.

[0033] A water pipe 2 is installed inside the detection box 1, and the water pipe 2 is connected to the train's water supply system through pipe joints 21 at both ends. When water enters the water pipe 2, the detection component 3 is controlled by the display and controller 11 to detect the water quality. The detection results and process can be displayed and alerted by the display and controller 11, and the detection control information is transmitted through the communication interface 12 on the outside of the detection box 1. Specifically, the communication interface 12 includes a CAN bus and an LTE-M module, which are used to connect the train control system and the train-to-ground data remote transmission, respectively, to ensure real-time monitoring of the detection control process. During the detection process, the water quality is monitored through the pipe 2. The leak detection strip 4 at the bottom of connector 21 detects leaks at the connection points of the two ends of the water pipe 2. If one or both connectors 21 leak, the leak detection strip 4 will be affected by the water, causing the signal collected by the display controller 11 to change. At this time, the display controller 11 can issue an alarm for leak detection to facilitate timely maintenance. The detection principle of the leak detection strip 4 is based on the principle of liquid conductivity. When the leak detection strip 4 comes into contact with water, the two sensing wires will short-circuit, causing a change in resistance. The display controller 11 judges the leak based on the change in resistance and issues an alarm signal. This principle is existing technology and will not be elaborated here.

[0034] Reference Figure 3 and Figure 4 The water pipe 2 is arranged in an "S" shape inside the detection component 3. The detection component 3 includes a mounting plate 31 fixedly installed inside the detection box 1. A clamping plate 32 for fixing the water pipe 2 is fixedly installed on the top of the mounting plate 31. A water quality detector 33 for detecting the water quality inside the water pipe 2 is fixedly installed on the outside of the clamping plate 32. A groove 34 is opened on the inside of the clamping plate 32 corresponding to the connection between the water quality detector 33 and the water pipe 2 for installing a leak detection belt 4.

[0035] The S-shaped water pipe 2 is fixed by the clamp 32 to ensure the stability of the water pipe 2. The water quality detector 33, which is carried on the outside of the clamp 32, is connected to the water pipe 2 and can detect water as it passes through the water pipe 2. The water quality detector 33 can be a residual chlorine sensor, turbidity sensor or other sensor for detecting water quality. In order to prevent leakage at the connection between the water quality detector 33 and the water pipe 2, a leakage detection strip 4 can be installed separately on the inside of the clamp 34 to detect leakage and ensure the stability of the operation of the water quality detector 33.

[0036] Reference Figure 3 and Figure 5 A vertical plate 35 is fixedly installed on the outside of the mounting plate 31 and the clamping plate 32 to fix two pipe joints 21. The two pipe joints 21 are arranged in a collinear manner. The leakage detection band 4 is circular. An arc-shaped support plate 41 is provided on the inside of the leakage detection band 4. An end plate 42 is fixedly installed on one side of the arc-shaped support plate 41. An arc-shaped support plate 43 is fixedly installed on the outside of the end plate 42 corresponding to the bottom of the leakage detection band 4. The arc-shaped support plate 41 and the arc-shaped support plate 43 are used to support the leakage detection band 4 located at the bottom of the pipe joint 21. An operation port 44 is opened at the bottom of the end plate 42 corresponding to the pipe joint 21.

[0037] The leak detection strip 4 is positioned normally by setting up the arc-shaped support plate 41 and the arc-shaped bracket 43, so that the leak detection strip 4 can be located at the bottom of the two pipe joints 21 for leak detection. The arc-shaped support plate 41 and the arc-shaped bracket 43 are supported by the end plate 42 to ensure the stability of the overall structure. Furthermore, to facilitate adjustment and replacement of the leak detection strip 4, refer to... Figure 3 and Figure 5 A drive shaft 45 is detachably installed on the inner side of the end plate 42. A motor 46 is installed at one end of the drive shaft 45. The motor 46 is fixedly installed on the outer side of the clamping plate 32, and the drive shaft 45 is rotatably connected to the vertical plate 35. A bolt 47 is fixedly installed at the other end of the drive shaft 45, and a nut 48 is threaded on the outer side of the bolt 47. The motor 46 can be controlled by the display controller 11 to drive the end plate 42 to rotate a certain angle through the drive shaft 45. In order to prevent the end plate 42 from interfering with the connection of the pipe connector 21, an operating port 44 is provided at the bottom of the end plate 42 for the pipe to pass through. The end plate 42 can be disassembled and fixed from the outside of the drive shaft 45 by rotating the nut 48 to ensure the flexibility of use.

[0038] In summary, when using the sanitary detection controller for the EMU water supply system disclosed in this application embodiment, the back plate 13 on the back of the detection box 1 is opened, the pipe fittings of the EMU water supply system are passed through the pipe hole 14, and then connected to the two pipe joints 21 inside the detection box 1. After connection, the end plate 42 is assembled on the outside of the drive shaft 45. At this time, the leakage detection belt 4 is located at the bottom of the two pipe joints 21 with the support of the arc-shaped support plate 41 and the arc-shaped support plate 43. Finally, the back plate 13 is fixedly installed. When the EMU water supply system supplies water to the water pipe 2, the water quality is detected by the water quality detector 33 on the outside of the clamp 32. The detection result is displayed by the display controller 11 on one side of the detection box 1. The display controller 11 can transmit the detection control data through the communication interface 12.

[0039] During water quality testing, if a leak occurs at the connection of pipe joint 21, a leak signal can be collected by the leak detection strip 4. That is, when the leak detection strip 4 comes into contact with water, the two sensing wires will short-circuit, causing a change in resistance. The display and controller 11 judges the leak situation based on the change in resistance and issues an alarm signal. After the leak detection strip 4 detects a leak once, the display and controller 11 controls the motor 46 to run, so that the motor 46 drives the end plate 42 to rotate a certain angle through the drive shaft 45, thereby driving the leak detection strip 4 to rotate and adjust the position corresponding to the pipe joint 21. This prevents the previous leak detection from interfering with the detection results of the leak detection strip 4. At the same time, the part of the leak detection strip 4 that came into contact with water can be transferred to facilitate subsequent drying.
