Fire extinguishing structure preventing fire spreading

Abstract

The invention discloses a fire extinguishing structure preventing fire spreading. The fire extinguishing structure preventing fire spreading comprises a fixed barrel. A direct-current pipe is installed in the fixed barrel. Two arc-shaped lateral flow channels are formed between the direct-current pipe and the inner wall of the fixed barrel. A direct-current water channel is arranged in the direct-current pipe. A current-limiting cap is arranged at the top end of the direct-current pipe, and the top of the current-limiting cap protrudes upwards. The current-limiting cap is composed of a plurality of current-limiting sheets which are annularly distributed on the end face of the top end of the direct-current pipe. The thickness of each current-limiting sheet gradually increases from the top end of the current-limiting sheet to the end face of the upper end of the direct-current pipe. A plurality of spiral protrusions are further installed at the tail end of the direct-current water channel. A deflector is rotationally arranged on the outer wall of the extension end of the direct-current pipe. A plurality of fire extinguishing structures preventing fire spreading can be used in a matched mode, i.e., the fire extinguishing structures preventing fire spreading are installed on the sidewall of a storage rack and the bottom of a crossbeam respectively, a plurality of oil tanks or a single oil tank is covered omni-directionally. Once the storage rack is on fire, a fire fighting water channel is used for immediately spraying the oil tanks through the direct-current water channel and the lateral flow channels. Non-blind-spot spraying on the oil tanks is guaranteed and safe storage of the oil tanks is ensured.

Description

technical field [0001] The invention relates to logistics storage equipment, in particular to a fire extinguishing structure for blocking the spread of fire. Background technique [0002] Oil is flammable, explosive, etc. During the process of oil transfer, storage, and equipment maintenance, it must be operated in strict accordance with standardized and standardized operating procedures. Especially in the process of oil transfer storage, in order to facilitate the quick selection of barreled oil, it is usually lifted to the multi-functional storage rack, so as to make reasonable use of the storage space and facilitate management and operation. It is worth noting that a sprinkler system must be installed on the storage rack to deal with sudden fire situations in time. However, when a fire occurs in the sprinkler system, the fire water will be evenly sprinkled through the sprinkler head, which will play a role in the fire in a certain area. control, and the common types of s...

It is worth noting that a sprinkler system must be installed on the storage rack to deal with sudden fire situations in time. However, when a fire occurs in the sprinkler system, the fire water will be evenly sprinkled through the sprinkler head, which will play a role in the fire in a certain area. control, and the common types of sprinkler heads are drooping type, vertical type, common type and side wall type. The spraying range of the above-mentioned sprinkler heads is generally determined, that is, to make up for the local blind area in the fire protection area, generally increase in the fire protection area. The number of sprinklers is in order to achieve its purpose. When extinguishing a fire, a large amount of firefighting water will be consumed, and the fire suppression efficiency is low. At the same time, due to the high temperature environment, a large area of ​​water vapor is formed in the fire prevention zone, which is not conducive to the safety of firefighters during subsequent treatment. transfer of oil
