Movable type fire protection extinguishment method used for electrical power tunnel

Abstract

The invention discloses a movable type fire protection extinguishment method used for an electrical power tunnel. By means of the method, fire vehicles can be dispatched to corresponding positions when fire protection dangers happen, and fire extinguishers are remotely controlled by a platform or locally started for extinguishment. In order to shorten the time spent on reaching an accident site, vehicle parking points are arranged on the tunnel at certain intervals, and the fire vehicles are placed at the fire vehicle parking points. The method is high in intelligent degree, light in weight, small in size, moderate in manufacturing cost, flexible in configuration, simple in path, low in maintenance cost and capable of completely achieving tasks and purposes of video surveillance, fire protection touring and linked extinguishment in the electric power tunnel. The movable type fire protection extinguishment method solves the problems that existing monitoring devices used for fire protection and extinguishment in the electrical power tunnel are generally monitoring type cameras which can hardly meet the application in the closed and semi-closed environment of the electrical power tunnel and have the insurmountable defects and disadvantages of being short in service life, narrow in monitoring range and high in maintenance cost.

Description

technical field [0001] The invention relates to a mobile fire extinguishing method for an electric power tunnel. Background technique [0002] At present, the monitoring equipment used for fire fighting and fire extinguishing in the power tunnel is generally a monitoring camera, and the monitoring camera installed follows the method of the security industry and the general industrial environment. From the protection level, it is divided into general protection and waterproof and dustproof, from explosion-proof The types are divided into explosion-proof type and ordinary type. From the point of view of the head, it can be divided into manual type and automatic type. From the appearance, it can be divided into fixed gun type and medium-speed dome type. From the signal point, it can be divided into analog camera and digital network camera type. , to meet the monitoring needs of general security occasions.

Problems solved by technology

[0003] However, the cameras that are popular in the traditional security industry are difficult to meet the application in the closed and semi-closed environment of power tunnels, and have various disadvantages and insurmountable defects:

[0004] First of all, there is the problem of lifespan. Because the tunnel is a closed environment, the lighting conditions are poor or not at all, so the camera works in night mode for a long time, and the laser light works continuously. Due to its characteristics, the service life is greatly shortened, especially the heat dissipation of explosion-proof cameras is not good. Under certain conditions, it will be replaced every quarter. Sometimes in order to prolong its life, it has to be sacrificed at the expense of video effects. The design reduces lighting power and reduces heat dissipation, which greatly reduces the role of camera security and high maintenance costs;

[0005] Secondly, both the trigger and the dome camera are installed in a fixed position, and the monitoring distance, angle, and range are limited, and it is impossible to see clearly beyond tens of meters. It can only realize simple monitoring of personnel. The monitoring of internal cables or equipment will greatly increase the installation density of cameras, which is expensive and cannot solve the problem of dead spots in the monitoring of equipment in tunnels; again, most cameras installed in tunnels use 220VAC AC power supply and optical fiber transmission signals; power supply distance The distance, the number of cameras is large, the power consumption is high, the voltage drop and loss of the line are high, and the number of optical fiber fusion splices has increased sharply. Due to the harsh environment of the tunnel, the water immersion and corrosion of the line will cause high maintenance costs in the later stage, and it cannot be used in the harsh environment of the power tunnel.
