[0002] A straddle-type monorail train is a rail transit vehicle that runs on a track beam that integrates the beam and the rail. The vehicle usually uses rubber wheels. When the rubber wheels are made of high flame-retardant rubber material, although the flame retardancy is good, there are disadvantages such as short life, high elastic modulus, and insufficient rubber viscosity during emergency braking, which can cause slippage. When the rubber wheels are made of low flame-retardant rubber material, although the disadvantages of high flame-retardant rubber material can be overcome, the low flame retardancy poses a fire problem due to the friction between the rubber wheels and the track during train operation.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0024] As mentioned in the background section above, while using low-flame-retardant rubber materials for the rubber wheels of straddle-type monorail trains can overcome the disadvantages of high-flame-retardant rubber materials, the low flame retardancy still poses a fire risk due to friction between the rubber tires and the track during train operation. Therefore, the inventors of this application provide a fire prevention system for the rubber wheels of the bogies of straddle-type monorail trains in one or more embodiments. This system achieves fire prevention through a cooling device and enables timely detection and effective extinguishing of fires through monitoring and fire-fighting devices, thereby ensuring the safety of train operation and personnel. It is believed that this system can solve one or more problems in the prior art.

[0025] To address the aforementioned technical problems, this invention provides a fire prevention system for the rubber wheels of a straddle-type monorail train bogie, comprising: a cooling device, which includes a temperature monitoring module and a cooling module, both installed on the rubber wheels of the train bogie for temperature monitoring and cooling of the rubber wheels; a monitoring device, installed on the rubber wheels for fire monitoring; a fire extinguishing device, installed on the rubber wheels for extinguishing fires on the rubber wheels; and a control device, wherein the temperature monitoring module is connected to the control device and transmits the monitored temperature of the rubber wheels to the control device, the control device is connected to the cooling module and sends cooling commands to the cooling module, the monitoring device is connected to the control device and transmits detected fire information to the control device, and the control device is connected to the fire extinguishing device and sends fire extinguishing commands to the fire extinguishing device.

[0026] Specifically, during train operation, the temperature monitoring module collects the temperature of the rubber wheels in real time and transmits it to the control device. When the collected temperature exceeds a set threshold, the control device sends a command to the cooling device, which then activates to cool the rubber wheels. When the temperature monitoring module detects that the rubber wheel temperature has returned to below the threshold, the control device sends a command to the cooling device to stop cooling, and the cooling device ceases cooling. In the event of a fire, the monitoring device sends a fire signal to the control device, which then issues a fire extinguishing command to the fire suppression system.

[0027] Compared with existing technologies, the fire prevention system for rubber wheels of straddle-type monorail train bogies provided by this invention achieves fire prevention through a cooling device, and can detect and effectively extinguish fires in a timely manner through a monitoring device and a fire extinguishing device, thereby ensuring the safety of train operation and personnel.

[0028] In some embodiments, the monitoring device includes a smoke monitoring module and a video monitoring module. Specifically, the fire extinguishing mode can be either a manual fire extinguishing mode or an automatic fire extinguishing mode. In the manual fire extinguishing mode, the video monitoring module acquires images of the rubber tires in each area and then transmits the images to the control device. The data processing board of the control device saves the compressed image files. When a fire occurs in a certain area of ​​the rubber tires, the smoke monitoring module detects the smoke and transmits it to the CPU board of the control device, issuing a fire alarm signal. The crew determines whether the fire in their area is real through the real-time video monitoring module. If it is a false alarm, the fire alarm is cleared. If the smoke monitoring module detects a correct signal, the crew presses the fire extinguishing button on the control module to issue a fire extinguishing command to the fire extinguishing module. In the automatic fire extinguishing mode, when both the signals sent to the control device by the video monitoring module and the smoke monitoring module are abnormal, the control device automatically issues a fire extinguishing command to the fire extinguishing device to extinguish the fire. The automatic fire extinguishing mode automates the fire extinguishing operation, while the manual mode avoids the problem of false alarms causing the fire extinguishing device to be activated when there is no fire.

[0029] In some embodiments, the temperature detection module further includes multiple temperature sensors, each mounted on a multiple rubber wheel; the cooling module includes multiple cooling nozzles, each mounted on a multiple rubber wheel; the smoke detection module includes multiple smoke detectors, each mounted on a multiple rubber wheel; the video detection module includes multiple high-definition cameras, each mounted on a multiple rubber wheel; and the fire extinguishing device includes multiple fire extinguishing nozzles, each mounted on a multiple rubber wheel. By using multiple temperature sensors, multiple cooling nozzles, multiple smoke detectors, multiple high-definition cameras, and multiple fire extinguishing nozzles, fire prevention, fire monitoring, and fire extinguishing can be performed on the rubber wheels in various areas of the train, further ensuring train safety.

[0030] In some embodiments, the cooling nozzle is rotatably mounted on the rubber wheel. When cooling the rubber wheel, rotating the cooling nozzle allows the cooling water sprayed from the nozzle to cover the rubber wheel to the maximum extent, thereby improving the cooling effect and efficiency.

[0031] In some embodiments, the fire extinguishing nozzle is rotatably mounted on a rubber wheel. The rotation of the fire extinguishing nozzle ensures that the extinguishing gas ejected from it is directly sprayed onto the point of ignition. Simultaneously, the rotation of the nozzle also directs the extinguishing gas to other parts of the rubber wheel, preventing further ignition and ensuring effective fire suppression.

[0032] In some embodiments, a cooling water tank is also included, which is connected to the cooling nozzle to provide cooling water for the cooling nozzle. The cooling water tank ensures the supply of cooling water required by the cooling nozzle. Specifically, the cooling water tank can be installed on the train, and further, one or more cooling water tanks can be installed.

[0033] In some embodiments, a fire extinguishing gas tank is also included, which is connected to the fire extinguishing nozzle to provide fire extinguishing gas to the nozzle. The fire extinguishing gas tank ensures the fire extinguishing gas required by the fire extinguishing nozzle. Specifically, the fire extinguishing gas tank may be installed on the train, and further, one or more fire extinguishing gas tanks may be installed.

[0034] In some embodiments, an alarm device is also included, which is connected to the control device to issue an alarm in the event of a fire. When the rubber wheel catches fire, the control device sends an alarm command to the alarm device, which then issues an alarm to enable personnel to take timely and appropriate action.

[0035] In some embodiments, the alarm device includes alarm lights and alarm broadcasts. Specifically, the alarm lights may be installed in the driver's cab, and the alarm broadcasts may be installed in each carriage of the train. When a fire occurs in the rubber tires, the alarm lights flash to alert staff to take appropriate action; when a fire occurs, the alarm broadcasts are made to ensure that passengers can evacuate in a timely manner.

[0036] In some embodiments, a backup power supply is also included, which is connected to the fire protection system to supply power to the fire protection system when the main power supply of the train is insufficient. The backup power supply avoids the problem of the fire protection system failing to function properly when the main power supply of the train is insufficient. Specifically, the backup power supply is also installed on the train, and further, one or more backup power supplies may be included.

[0037] In summary, compared to existing technologies, the fire prevention system for the rubber wheels of a straddle-type monorail train bogie provided by this invention achieves fire prevention through a cooling device, and can promptly detect and effectively extinguish fires through monitoring and fire extinguishing devices, thereby ensuring the safety of train operation and personnel. Through smoke monitoring and video monitoring modules, it can employ both automatic and manual fire extinguishing modes, achieving automation while avoiding misoperation. Multiple temperature sensors, multiple cooling nozzles, multiple smoke detectors, multiple high-definition cameras, and multiple fire extinguishing nozzles further ensure train safety. The rotation of the cooling and fire extinguishing nozzles ensures effective cooling and fire extinguishing. An alarm device alerts staff to take appropriate actions. A backup power supply prevents the fire prevention system from malfunctioning when the train's main power supply is insufficient.
