Embodiment 1

[0040] Embodiment 1: A mobile fire extinguishing system with rail fixed in the air for a tunnel, including 4 aerial track units, a fire extinguishing unit with a mobile trolley device, a high-pressure water supply unit, an external charging pile unit, and a fire alarm unit in the tunnel;

[0041] The fire extinguishing unit of the mobile car device includes a car device 10 and a fire extinguishing device 1, a water intake device 2, an internal charging device 3, a built-in rechargeable battery, and a control device arranged on the car device 10. The car device 10 is set on the aerial track 4 and can reciprocate along the air track 4;

[0042] The high-pressure water supply unit includes a plurality of water intakes 5 arranged along the aerial track, and each water intake 5 is connected to a high-pressure water supply pipe 6;

[0043] The external charging pile unit is arranged on the aerial track 4 .

[0044]The output end of the fire alarm unit in the tunnel is wirelessly co...

Embodiment 2

[0053] Example 2: figure 2 / 3 shows a preferred solution of the aerial track unit of the present invention, the aerial track unit includes a support track device 41, a side guide rail device 42, and an upper bearing cover device 43, corresponding to the above settings, the trolley device 10 is provided with support wheel set 11 and guide wheel set 12.

Embodiment 3

[0054] Example 3: Figure 4 / 5 / 6 shows a preferred solution of the centering device described in the present invention. The centering device includes an overtravel sensor 207, a centering sensor 201, a contact sensor 202, a centering sensor 204 is provided, and the positional relationship between the centering sensor 204 and the water intake 5 is consistent with the positional relationship between the centering sensor 201 and the water intake joint 19, and the rear end of the centering sensor 204 is provided with a contact sensor 203. The front end of the sensor 204 is provided with an overtravel sensor 208, and the distance between the overtravel sensor 207, the centering sensor 201, and the contact sensor 202 is smaller than the distance between the corresponding overtravel sensor 208, the centering sensor 204, and the contact sensor 203. Distance, wherein the difference between the distance between the overtravel sensor 208 and the centering sensor 204 and the distance betw...

Abstract

The invention relates to the technical field of fire protection, in particular to a tunnel aerial rail-determination-type moving fire extinguishing system. The tunnel aerial rail-determination-type moving fire extinguishing system comprises an air rail unit, a moving trolley device fire extinguishing unit, a high-pressure water supply unit, an external charging pile unit and a tunnel interior firealarming unit. After the tunnel interior fire alarming unit detects a fire in a tunnel, information is transmitted to a control device through wireless signal transmission, the moving trolley devicefire extinguishing unit is detached from the external charging pile unit and moves to a water taking opening closest to the fire occurrence position along a rail in the tunnel through automatic speedchanging, and a water taking device on a trolley device takes water to convey the water to the fire point to extinguish the fire; and after the fire is extinguished, the water taking device is automatically disconnected from the water taking opening and closes the water taking opening, and the moving trolley device fire extinguishing unit returns back to the external charging pile unit to be connected with a charging power supply through an internal charging device to charge and power off a built-in charging battery.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a mobile fire extinguishing system with fixed tracks in the air for tunnels. Background technique [0002] The fire protection design requirements stipulate the fire protection facilities of narrow and long buildings such as tunnels, mainly including fire hydrant systems, automatic sprinkler systems, automatic fire alarm systems, smoke control systems, communication systems, fire extinguishers, emergency lighting and evacuation signs, etc. The fire extinguishing method adopts fire hydrant system, automatic sprinkler system and fire extinguisher, and the fixed-point layout adopted by this fire extinguishing device. [0003] Among them, the automatic sprinkler system and fire hydrant system have limited application scope: they are not suitable for extinguishing hydrocarbon and electrical fires, and need to divide the tunnel into multiple partitions; fire extinguishers are a...
