[0002] Urban rail transit is usually equipped with a signal control cabinet to monitor whether the operation of the urban rail is normal, which plays a great role in protecting the lives of passengers and equipment safety, and improving the management level and service quality of urban rail transit. At present, the signal control cabinet usually includes a control console, a feedback device and several signal acquisition devices, and the control console, feedback device and several signal acquisition devices are all electrically connected. However, since the control cabinet is in operation for a long time, the power transmission of the control cabinet will generate heat, and the current control cabinet has poor heat dissipation function, the temperature inside the control cabinet will become higher and higher. When the temperature is too high, it is easy to damage the original parts inside the control cabinet.

[0003] The existing rail transit signal control cabinet cannot promptly and effectively extinguish the fire when a fire occurs. Utility Model Content
