Embodiment Construction

[0034] The following is attached Figure 1-5 The application is described in further detail.

[0035] The embodiment of the present application discloses a cable tunnel fire prevention system.

[0036] refer to figure 1 , a cable tunnel fire prevention system, including a hanger 1, a tank 2 for storing carbon dioxide and a storage tank 3 for storing a fire extinguishing agent. The fire extinguishing agent can be a dry powder fire extinguishing agent or calcium bicarbonate. Both the tank body 2 and the storage tank 3 are made of pressure-resistant stainless steel, and the tank body 2 is fixedly arranged below the storage tank 3 .

[0037] refer to figure 1 , figure 2 , The hanger 1 includes a fixed rod 11 and a movable rod 12 , and the movable rod 12 slides through the fixed rod 11 . The bottom wall of the movable rod 12 is fixedly connected with the storage tank 3 . The fixed rod 11 is provided with a limit piece for limiting the position of the movable rod 12. The mova...

Abstract

The application relates to a cable tunnel fire protection system, which belongs to the technical field of fire protection engineering, and includes a hanger, a tank body and a material storage tank. The outlet pipe connected to the tank body is provided with a valve, and the end of the outlet pipe away from the tank body is connected with a first branch pipe and a second branch pipe. The first branch pipe is connected with the storage tank, and the storage tank is connected with a feed pipe. The feeding pipe communicates with the spray pipe; the second branch pipe communicates with the casing. When a fire breaks out, the fire extinguishing agent in the storage tank forms a gas-solid mixture under the action of high-pressure carbon dioxide gas, and then enters the nozzle, while a part of the carbon dioxide gas enters the casing and then sprays out, and the carbon dioxide gas emitted from the casing Wrapped in the gas-solid mixture to form a protective layer, so that the fire extinguishing agent can reach the fire source smoothly and attach to the line, effectively improving the fire extinguishing effect.

Description

technical field [0001] The present application relates to the technical field of fire protection engineering, in particular to a cable tunnel fire protection system. Background technique [0002] A cable tunnel is a corridor or tunnel structure used to accommodate a large number of cables laid on cable supports. In addition to allowing the tunnel to better protect the cables, the cable tunnel can also make it easy for people to inspect and repair the cables. Electric and cable equipment generally adopt fine water mist fire extinguishing system. [0003] However, the water in the water mist fire extinguishing system is easy to conduct electricity, and electrical accidents such as grounding, short circuit, and blasting of electrical and cable equipment when exposed to water are prone to electrical accidents such as grounding, short circuit, and blasting. low efficiency. Contents of the invention [0004] In order to improve the fire extinguishing efficiency of cables, the...
