Embodiment Construction

[0020] see figure 1 Shown: the present invention will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0021] The invention provides a single-point fixed fire pre-control device for subway electrics, such as figure 1 As shown, it includes an infrared camera 5, a monitoring computer 8, a camera signal line 7, a dry powder fire extinguisher 2, a control valve 3; a spray outlet 4 and a fire extinguisher signal line 6, and the electrical box 1 of the application object of the present invention.

[0022] The infrared camera 5 is connected with the monitoring computer 8 through the camera signal line 7, and the control valve 3 of the dry powder fire extinguisher 2 is connected with the monitoring computer 8 through the fire extinguisher signal line 6. The dry powder fire extinguisher 2 is arranged 20cm above the electrical box 1, and the infrared camera 2 is about 40cm away from the electrical box 1. Dry powder fire extinguisher 2 an...

Abstract

The invention provides a single-point fixed type fire precontrolling device for a subway electrical cabinet. A dry powder fire extinguisher is arranged over the electrical cabinet in a subway. A control valve is connected to a spray nozzle of the dry powder fire extinguisher. The spray nozzle of the dry powder fire extinguisher is opposite to the electrical cabinet. The control valve is connected with a control computer through a fire extinguisher signal line. An infrared camera which is opposite to the electrical cabinet is also arranged above the electrical cabinet in the subway. The infrared camera is connected with the control computer through a camera signal line. The single-point fixed type fire precontrolling device has the beneficial effects that the device is fixedly mounted on the periphery of the electrical cabinet in the subway; in the device, the infrared camera monitors the temperature, the monitoring computer analyzes data, and the dry powder fire extinguisher responds to signals so that during a subway fire, temperature changes of the electrical cabinet can be monitored, and a possible electrical fire can be dealt with in time; accordingly, the problems that an electrical fire occurs suddenly, is hard to monitor and is not dealt with in time are solved, and the decision-making speed and the safety of a subway structure during subway operation and maintenance are guaranteed more effectively.

Description

technical field [0001] The invention relates to the technical field of subway fire pre-control devices, and belongs to a single-point fixed fire pre-control device for subway electrics. Background technique [0002] According to the analysis and induction of the causes of subway fires at home and abroad, the following five types can be obtained: electrical causes, mechanical causes, accidental open flames, artificial arson, and other causes. [0003] (1) Electrical reasons. Including circuit short circuit (including locomotive circuit, tunnel circuit, station circuit, regardless of lighting or power), electrical device failure (including electric heating and air conditioning, lamps), power supply system failure (including transformer, collector, rectifier, machine room), etc. [0004] (2) Mechanical reasons. Refers to vehicle operation errors, mechanical collision sparks, and vehicle fires for unknown reasons. [0005] (3) Accidental fire. It is further divided into two ...
