Description

Technical Field

[0001] The utility model relates to fire extinguishing equipment, in particular to automatic water spraying fire extinguishing equipment used in fire-fighting construction projects, and belongs to the technical field of fire-fighting water spraying. Background Art

[0002] Fire refers to a disaster caused by combustion that is out of control in time or space. The new standard defines fire as combustion that is out of control in time or space. Fire is one of the most frequent and common major disasters that threaten public safety and social development. In fire protection construction projects, fires are often caused by temperature, emergencies or gas leaks. In order to prevent the rapid spread of fire, automatic sprinkler fire extinguishing equipment will be needed.

[0003] Among them, the "automatic sprinkler fire extinguishing equipment with adjustable height" disclosed in application number "202323494899.0" "comprises a wall, the inner cavity of the wall is provided with a lifting pipe, the bottom of the lifting pipe is fixedly connected to a sprinkler head body, the number of the sprinkler head bodies is five, and one side of the inner cavity of the wall is fixedly connected to a water tank." In the present utility model, the water adding pipe is used to add water to the interior of the water tank. At the same time, since the interior of the water tank can store a certain amount of water, when the water adding pipe is cut off, the water inside the water tank can still be used for fire extinguishing operations. The lifting mechanism is used to adjust the height of the lifting pipe, thereby adjusting the height of the water spraying, which can effectively prevent the sprayed water from being too dispersed due to the position of the sprinkler head body being too high, thereby reducing the fire extinguishing efficiency.

[0004] However, this approach also has drawbacks: While the height of the lifting tube can be adjusted using a lifting mechanism to prevent excessive dispersion of the water, the current sprinkler system's nozzle configuration is limited, primarily by its fixed spray direction, making it difficult to flexibly adapt to diverse practical environments. This one-way spray pattern limits the range and accuracy of firefighting, preventing the nozzles from precisely targeting the core of the fire, thus impacting overall firefighting effectiveness and efficiency.
