[0002] The bead-walking quick color changing system can be applied to quick filling, recycling, cleaning and precise metering of paint, so as to reduce the waste of materials to a very low level, and shorten the cleaning and color changing time of the system.

[0003] At present, the liquid supply pipeline in the distribution station of the bead-walking quick color changing system may leak. For large leakage points, relevant personnel can find the leakage and find the leakage point through the abnormality of liquid level or pressure, but for small leakage points and seepage, only the leakage point can be found through visual inspection, therefore, it is an urgent problem to quickly and accurately find the leakage point.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Rollerball-type rapid color-changing systems can be applied to the rapid filling, recycling, cleaning, and precise metering of paint, minimizing material waste and shortening system cleaning and color-changing times. During the paint filling process, leaks may occur at the distribution station of a rollerball-type rapid color-changing system. To quickly and accurately locate leaks, this application discloses a pipeline leak detection and handling device for the distribution station of a rollerball-type rapid color-changing system.

[0027] Reference Figure 1 and Figure 2 A pipeline leakage detection and treatment device for a distribution station of a ball-type rapid color-changing system includes a leakage receiving plate 1, a leakage collection tank 2, a leakage ball valve 3, a waste liquid pipeline 4, a capacitive detection switch 5, a control module 6, an alarm module 7, and a power supply module 8.

[0028] The leak collection tray 1 is located directly below the target distribution station and is a funnel-shaped tray. This funnel-shaped tray collects the leaked liquid, reducing the risk of large-scale ground pollution. A leak collection tank 2 is fixedly installed at the bottom of the leak collection tray 1 and is connected to it, allowing the leaked liquid collected by the tray to flow into the tank.

[0029] A capacitive detection switch 5 is fixedly installed inside the leak collection tank 2. This switch detects leaks at the target distribution station and outputs a leak detection signal. When leaking liquid approaches the switch, the dielectric constant of the capacitor changes, causing a change in capacitance and consequently altering the circuit state, thus triggering a leak detection signal. A control module 6 is connected to the capacitive detection switch and outputs a control signal upon receiving the leak detection signal. An alarm module 7 is connected to the control module 6 and triggers an alarm upon receiving the control signal, notifying personnel to repair the leak. In this embodiment, the control module 6 is preferably a PLC controller, and the alarm module 7 is preferably an audible and visual alarm.

[0030] One end of the waste liquid pipeline 4 is fixedly connected to the bottom of the leakage collection tank 2, and the other end is fixedly connected to the liquid source. The waste liquid pipeline 4 is used to allow the leakage in the leakage collection tank 2 to flow back to the liquid source, reducing liquid waste. The leakage ball valve 3 is fixedly installed at the connection between the leakage collection tank 2 and the waste liquid pipeline 4. The leakage ball valve 3 is connected to the control module 6. The leakage ball valve 3 is used to open after receiving a control signal, allowing the leakage in the leakage collection tank 2 to flow into the waste liquid pipeline 4. It can be known that the leakage ball valve 3 is normally closed.

[0031] The power supply module 8 is connected to the capacitive detection switch 5, the control module 6, the alarm module 7, and the leakage ball valve 3, respectively, providing power to these components. Furthermore, this application transforms periodic inspections into 24 / 7 real-time electrical signal monitoring, improving worker efficiency. In this embodiment, the power supply module 8 is preferably an external power source.

[0032] The implementation principle of a pipeline leakage detection and treatment device for a ball-type rapid color-changing system distribution station in this application embodiment is as follows: When there is leakage, the leakage receiving plate 1 and the leakage collection tank 2 collect the leakage. The capacitive detection switch 5 is affected by the leakage, causing the dielectric constant of the capacitor to change, thereby changing the capacitance, which in turn changes the circuit state and outputs a leakage detection signal. After receiving the leakage detection signal, the control module 6 outputs a control signal. After receiving the control signal, the alarm module 7 starts to alarm, notifying the staff to repair the leak location. After receiving the control signal, the leakage ball valve 3 opens, allowing the leakage in the leakage collection tank 2 to flow back to the liquid source through the waste liquid pipeline 4.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
