Spraying system for increasing fire prevention level of storage warehouse

Abstract

The invention discloses a spraying system for increasing the fire prevention level of a storage warehouse. The spraying system comprises a fixing cylinder, a straight flow pipe is installed in the fixing cylinder, two arc-shaped lateral flow channels are formed between the straight flow pipe and the inner wall of the fixing cylinder, and a flow limiting cap of which the top protrudes out upwards is arranged at the top end of the straight flow pipe and composed of multiple flow limiting sheets; a movable groove is formed in the middle of a straight flow water channel, two flow limiting plates which are vertically distributed in a spaced mode are arranged in the movable groove, the upper portion and the lower portion of the straight flow water channel communicate with a hose penetrating through the two flow limiting plates through ends, and a water splashing disc is rotatably arranged on the outer wall of the extending end of the straight flow pipe. According the spraying system for increasing the fire prevention level of the storage warehouse, multiple spraying systems can cooperate with one another for use, that is to say, the spraying systems are installed on the side walls of a storage rack and the bottom of a cross beam, multiple or one oil barrel is all-dimensionally covered, fire fighting water sprays the oil barrels through the straight flow water channel and the lateralflow channels once the storage rack is fired, it is guaranteed that no blind spot exists in spraying of the oil barrel, and safe storage of the oil barrels is guaranteed.

Description

technical field [0001] The invention relates to the protection field of storage warehouses, in particular to a sprinkler system for improving the fire protection level of storage warehouses. Background technique [0002] In view of the storage characteristics of the existing large warehouses, safety measures need to be taken according to the physical and chemical properties of the materials. For example, the oil warehouse needs to improve the fire protection level of the warehouse when it is built. Generally, the storage rack must be equipped with sprinklers. The system responds to sudden fire situations in a timely manner, but when a fire occurs in the sprinkler system, the fire water is evenly sprayed through the sprinkler head to control the fire in a certain area, and the common types of sprinkler heads are drooping type and vertical type , common type and side wall type, the spraying range of the above-mentioned sprinklers is generally determined, that is, to make up fo...

[0002] In view of the storage characteristics of the existing large warehouses, safety measures need to be taken according to the physical and chemical properties of the materials. For example, the oil warehouse needs to improve the fire protection level of the warehouse when it is built. Generally, the storage rack must be equipped with sprinklers. The system responds to sudden fire situations in a timely manner, but when a fire occurs in the sprinkler system, the fire water is evenly sprayed through the sprinkler head to control the fire in a certain area, and the common types of sprinkler heads are drooping type and vertical type , common type and side wall type, the spraying range of the above-mentioned sprinklers is generally determined, that is, to make up for the local blind area in the fire prevention zone, the number of sprinklers is generally increased in the fire prevention zone to achieve its purpose, and the fire will consume A large amount of fire-fighting water, and the suppression efficiency of the fire is low. At the same time, due to the high-temperature environment, a large area of ​​water vapor is formed in the fire-proof zone, which is not conducive to the transfer of oil by firefighters during subsequent treatment.
