[0025] The control device is a winch 1, which is connected to a sprinkler pipe 3 via a steel wire rope 2. The steel wire rope 2 extends out of the building facade through a positioning bracket 9. A steel wire rope guide lock 10 is arranged at the upper end of the steel wire rope near the positioning bracket.

[0026] The movable bracket of the spray pipe 3 is arranged along the outer facade of the building, and the water supply device comprises a water supply hose 4 connected to the spray pipe 3 and a high-pressure water pump 5 connected to the water supply hose 4; the spray pipe 3 moves up and down along the outer facade of the building along the movable bracket of the spray pipe.

[0027] The spray pipe is horizontally arranged in multiple sections according to the lines and shapes of the building facade, and a plurality of spray ports 11 are arranged at equal intervals on the spray pipe.

[0028] The spray pipe is connected to a water supply hose 4 at intervals.

[0029] Specifically, this embodiment selects the installation and control of the device according to the following rules: The winch is placed in the positioning box, the counterweight is also placed in the positioning box, and the winch is fixed to the roof by high-strength bolts to ensure the safety of the test process. The front legs are used to fix and raise the positioning bracket. The wire rope guide lock is installed on the wire rope to limit the highest position of the sprinkler pipe (PVC pipe is selected as the sprinkler pipe in this embodiment).

[0030] Furthermore, the winch provides power to control the PVC spray pipe to move up and down and hover, ensuring that the spraying time of each layer meets the requirements.

[0031] Furthermore, at least one winch is arranged every 15m to ensure the required power for lifting and lowering.

[0032] Furthermore, the steel wire rope extends out of the wall through the positioning bracket, while ensuring the fixation of the position.
