[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A special grade steel fireproof rolling shutter door cooling spray device comprises a winding box 1 and a rolling shutter door body 2, wherein the rolling shutter door body 2 is wound in the winding box 1, and a plurality of water pipes 3 are fixedly arranged on the outer wall of the winding box 1, wherein the water pipes 3 are vertically attached to the winding box 1, and a plurality of spray heads 8 are connected to the bottom of the water pipes 3, wherein the spray heads 8 cooperate with the rolling shutter door body 2, and a connecting component is arranged on the top of the water pipes 3.

[0022] The water source is connected through the connecting component. After the water flows into the water pipe 3, it is sprayed out from the sprinkler head 8. The sprayed water flows toward the rolling shutter door body 2 in the closed state to cool down the rolling shutter door body 2, so as to prevent the rolling shutter door body 2 from being damaged by heat and unable to be opened. When the water flows in the water pipe 3, the winding box 1 will be cooled. The contact surface between the water pipe 3 and the winding box 1 is a flat structure, so the winding box 1 can be cooled well, and the practicability is high. The rolling shutter door body 2 and the winding box 1 are both made of special grade steel.

[0023] The above-mentioned connecting components can be any one. The present application proposes an embodiment, in which the connecting component includes a connecting pipe 4, a main pipeline 5 and a connecting port 6. The top of the water pipe 3 is connected to the connecting pipe 4, the top of the connecting pipe 4 is connected to the main pipeline 5, the top of the main pipeline 5 is connected to the connecting port 6, and a flange is provided on the connecting port 6, which is connected to the fire-fighting pipe through the flange. The water source in the fire-fighting pipe will enter the water pipe 3 through the connecting port 6, the main pipeline 5 and the connecting pipe 4.

[0024] The above structure needs to better cool the winding box 1 when in use. In order to meet the above requirements, multiple groups of heat sinks 7 are fixedly arranged on the outer wall of the winding box 1. The heat sink 7 is connected to the water pipe 3. When water flows through the water pipe 3, the heat sink 7 will be cooled and dissipated, thereby further cooling and dissipating the winding box 1.

[0025] In this embodiment, the water pipe 3 and the winding box 1 are welded and fixed, the water pipe 3 and the heat sink 7 are both made of copper, and a plurality of groups of the spray heads 8 are distributed front and back.
