[0001] This utility model relates to the field of gas leakage monitoring technology for rail transit vehicle pipelines, and in particular to a gas leakage monitoring device for rail transit vehicle pipelines. Background Technology

[0002] In modern rail transit systems, critical equipment such as vehicle braking systems, pneumatic control systems, and air conditioning rely on complex gas pipeline systems for energy transfer and functional control. The stable operation of these gas pipeline systems is crucial for ensuring train safety and improving operational efficiency. Gas leaks not only waste energy but can also affect the normal operation of the entire vehicle and even lead to safety accidents. Therefore, timely and accurate monitoring of gas leaks in rail transit vehicle pipeline systems has become an indispensable part of routine maintenance.

[0003] Currently, common vehicle pipeline gas leak detection mainly relies on a combination of manual inspections and handheld detection instruments. However, this method generally suffers from low detection efficiency, high false negative rates, and difficulty in accurately locating leak points. Furthermore, traditional detection methods typically require operators with high levels of professional skill and involve on-site, segment-by-segment inspections, which is time-consuming and fails to meet the demands of efficient operation and maintenance and intelligent development in modern rail transit systems.

[0004] Therefore, it is necessary to design a gas leakage monitoring device for rail transit vehicle pipelines to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional detection methods, which typically require operators with high professional skills and involve on-site, segment-by-segment inspections, resulting in long processing times and difficulty in meeting the needs of efficient operation and maintenance and intelligent development of modern rail transit systems, this utility model provides a gas leakage monitoring device for rail transit vehicle pipelines.

[0006] The technical solution is as follows: A gas leakage monitoring device for rail transit vehicle pipelines includes an electric slide rail, an electric slider, a support plate, a laser gas telemeter, a controller, a signal transmitter, and a spraying assembly. The electric slide rail serves as the mounting carrier. An electric slider is slidably connected to the top of the electric slide rail. A support plate is fixedly connected to the top of the electric slider. A laser gas telemeter is installed in the middle of the top of the support plate. A controller is installed on the top of the support plate behind the laser gas telemeter. A signal transmitter is installed on the front side of the top of the support plate. The electric slide rail, the laser gas telemeter, and the signal transmitter are all electrically connected to the controller. A spraying assembly is provided between the rear side of the support plate and the upper left and right sides of the laser gas telemeter.

[0007] To further explain, the laser gas telemetry instrument has a multi-angle laser adjustment module.

[0008] To further explain, the spraying assembly includes a mounting plate, a support frame, a liquid storage tank, a liquid pump, a mounting base, and a spray head. The mounting plate is fixedly connected to the top periphery of the support plate and to the rear side. The support frame is fixedly connected to the top rear side of the mounting plate. The liquid storage tank is fixedly connected to the middle of the support frame. Liquid pumps are installed on the left and right sides of the liquid storage tank. Mounting bases are fixedly connected to the left and right sides of the upper part of the laser gas telemetry instrument. The output port of each liquid pump extends to the front side of the corresponding mounting base. The output ports of the liquid pumps are all connected to and communicate with the spray head, and the liquid pumps are electrically connected to the controller.

[0009] To further explain, it also includes a bellows, with a bellows installed between the rear side of the spray head and the output port of the front side of the pump.

[0010] Further explanation: It also includes an observation panel, with the front and rear of the liquid storage tank extending out of the support frame. Observation panels are symmetrically arranged on both sides of the front and rear of the liquid storage tank, and an injection port is opened at the lower rear side of the liquid storage tank.

[0011] To further explain, it also includes a liquid filling pipe, with the liquid filling port at the lower rear side of the storage tank connected to the liquid filling pipe.

[0012] The beneficial effects are: 1. This utility model integrates a spraying component on a laser gas telemetry instrument and achieves automatic scanning and precise location of leak points through linkage control of electric slide rail and electric slider; when a gas leak is detected, the controller automatically triggers the spraying component to spray leak detection liquid in the leak area to form a visual mark, thereby realizing intelligent inspection, leak identification and rapid on-site location of the rail transit vehicle pipeline system, improving detection accuracy and ease of operation.

[0013] 2. This utility model uses a liquid supply system consisting of a storage tank, a pump, a corrugated pipe, and a spray head, along with an observation plate and a filling pipe, to achieve liquid status monitoring and convenient liquid replenishment, thus ensuring long-term stable operation of the device and improving maintenance efficiency.

Detailed Implementation

[0019] Example: A gas leak monitoring device for pipelines in rail transit vehicles, such as... Figures 1-4 As shown, the system includes an electric slide rail 5, an electric slider 6, a support plate 1, a laser gas telemeter 2, a controller 3, a signal transmitter 4, and a spraying assembly. The electric slide rail 5 serves as the mounting carrier. The electric slider 6 is slidably connected to the top of the electric slide rail 5. The support plate 1 is bolted to the top of the electric slider 6. The laser gas telemeter 2 is mounted on the top of the support plate 1. The controller 3 is mounted on the top of the support plate 1 at the rear side of the laser gas telemeter 2. The signal transmitter 4 is mounted on the front side of the top of the support plate 1. The laser gas telemeter 2 has a multi-angle laser adjustment module. The electric slide rail 5, the laser gas telemeter 2, and the signal transmitter 4 are all electrically connected to the controller 3. The spraying assembly is located between the rear side of the support plate 1 and the upper left and right sides of the laser gas telemeter 2.

[0020] like Figures 1-3 As shown, the spraying assembly includes a mounting plate 7, a support frame 8, a liquid storage tank 9, a liquid pump 10, a mounting base 13, a spray head 11, a bellows 12, an observation plate 14, and a liquid filling pipe 15. The mounting plate 7 is bolted to the top periphery and rear side of the support plate 1. The support frame 8 is bolted to the top rear side of the mounting plate 7. The liquid storage tank 9 is bolted to the center of the support frame 8. Liquid pumps 10 are installed on the left and right sides of the liquid storage tank 9. The upper left and right sides of the laser gas telemetry instrument 2 are bolted to the mounting base 13. The mounting base 13 has an output port of each pump 10 extending to the front of the corresponding mounting base 13. The output ports of the pumps 10 are all connected to and connected to a spray head 11. A corrugated pipe 12 is provided between the rear side of the spray head 11 and the output port of the pump 10. The mounting base also includes a storage tank 9 with its front and rear parts extending through the support frame 8. Observation plates 14 are symmetrically provided on the front and rear sides of the storage tank 9. An injection port is provided at the lower rear side of the storage tank 9. The injection port at the lower rear side of the storage tank 9 is connected to a liquid filling pipe 15. The pumps 10 are electrically connected to the controller 3.

[0021] Operators can apply the corresponding technical solutions in this device to the intelligent inspection and location detection of gas leaks in rail transit vehicle pipelines, depending on the specific circumstances. When this device is needed to assist in gas leak monitoring, firstly, the electric slide rail 5 is installed near the area to be detected. The laser gas telemetry instrument 2, equipped with a multi-angle adjustment module, will then conduct multi-angle, all-round gas leak inspections of the pipelines passing through the rail transit vehicle.

[0022] The controller 3 activates the electric slide rail 5, which drives the electric slider 6 to move. The electric slider 6 drives the support plate 1 and the laser gas telemetry instrument 2 installed on it to move synchronously. Under the control of the controller 3, the laser gas telemetry instrument 2 scans and detects the pipeline area to identify whether there is a gas leak in real time. The detection signal is transmitted to the external receiving device or monitoring system via the signal transmitter 4 to realize remote data interaction and status feedback.

[0023] The laser gas telemetry instrument 2, under the control of the controller 3, can perform high-precision gas leak scanning and detection on the pipeline system of rail vehicles. It has multi-angle adjustment function, which can adapt to pipeline layouts with different directions and heights, ensuring comprehensive coverage of the detection range. When the telemetry instrument detects a gas leak signal, the controller 3 immediately records the current position information and achieves precise positioning through the electric slider 6, thereby completing the intelligent identification and spatial positioning of the leak point.

[0024] Meanwhile, the controller 3 controls the signal transmitter 4 to send the detection results to an external monitoring terminal or maintenance management system in real time, facilitating remote monitoring and data analysis. If further confirmation of the leak location or enhancement of visualization is required, the controller 3 can trigger the spraying assembly to operate. The pump 10 draws leak detection liquid from the storage tank 9 and delivers it to the spray head 11 through the bellows 12 to aid in visualizing the leak point and improve detection accuracy. The spray head 11 is flexibly connected to the output port of the pump 10 through the bellows 12 to ensure stable liquid supply during operation. The storage tank 9 is fixedly installed at the rear of the device by the support frame 8. The remaining liquid level inside can be viewed in real time through the observation plate 14 and can be replenished through the filling pipe 15. The liquid status inside can be viewed in real time through the observation plate 14 located at the rear, and convenient replenishment can be performed through the filling pipe 15 at the filling port of the storage tank 9, ensuring the device's ability to operate continuously for extended periods.

[0025] The entire detection process is coordinated by the controller 3, which realizes closed-loop control of the entire process from automatic inspection, leak identification, location judgment to auxiliary visualization. This significantly improves the gas leak detection efficiency and intelligence level of the rail transit vehicle pipeline system, and has the advantages of fast response speed, accurate positioning and convenient operation.
