In specific implementation, the pipeline 201 can be made of a round steel pipe, and a side wall of the pipeline 201 is evenly provided with a plurality of openings 204. For example, in this embodiment, a total of 6 openings 204 are provided. The adjustment block 202 is rectangular, and a fixed joint for connecting the interface 203 is provided at one end, and a rotating joint for connecting the pipeline is provided at the other end. The two adjustment blocks rotate the joints and are rotatably connected to the pipeline 201. A blowing assembly 3 is fixedly connected to each opening 204 of the pipeline 201. That is, in this embodiment, a total of 6 blowing assemblies 3 are provided.

[0024] The pipe assembly 2 is rotatably connected to the support assembly 1 through two adjustment blocks 202, and the two adjustment blocks 202 are welded and fixed to the lower ends of the two brackets 102 of the two support assemblies 1. By rotating the rotating joint of the adjustment block, the pipe 201 drives the blowing assembly 3 to rotate, and the installation angle of the blowing assembly 3 and the support assembly 1 can be adjusted, so that the blowing nozzle 306 of the blowing assembly 3 can accurately align with the poor cooling position at the bottom of the leak plate.
