[0021] Among them, in this embodiment, two groups of spray pipes 1 are arranged at different heights of the diversion part, and are arranged alternately with each other, so as to ensure the spray coverage area while reducing the interference between the upper and lower spray pipes 1, so as to facilitate targeted inspection and maintenance. Specifically, the diversion part includes a first guide pipe 3 at the bottom, the bottom of the first guide pipe 3 is sealed, and an adjusting sleeve 4 is coaxially rotatably arranged on the upper end of the first guide pipe 3, and a second guide pipe 5 is rotatably connected to the adjusting sleeve 4, and the adjusting sleeve 4 and the second guide pipe 5 are both structures that are set up through the top and bottom, one group of spray pipes 1 is connected with the first guide pipe 3, and the other group of spray pipes 1 is connected with the second guide pipe 5; a diversion pipe 6 is arranged in the adjusting sleeve 4, and the diversion pipe 6 is a structure that is set up through the top and bottom, and the diversion pipe 6 can move up and down with the rotation of the adjusting sleeve 4 to respectively control the opening or closing of the guide port 10 on the first guide pipe 3 or the second guide pipe 5, so as to meet the switching operation of the two groups of spray pipes 1, which is easy to operate and has strong practicality.

[0022] Furthermore, sealing rings 7 are provided in the first guide tube 3 and the second guide tube 5, and the upper and lower ends of the shunt tube 6 can be in close contact with the sealing ring 7 to achieve sealing operation; an arc-shaped driving groove 8 is provided on the inner wall of the adjusting sleeve 4, and the driving groove 8 is opened in an arc shape from top to bottom on the inner wall of the adjusting sleeve 4, and a driving rod 9 is provided on the shunt tube 6 to slide in the driving groove 8, and the driving rod 9 is a cylindrical structure; a limiting guide is provided on the shunt tube 6 so that it can only move up and down; during operation, the adjusting sleeve 4 is rotated clockwise, and the driving groove 8 will push the driving rod 9 to drive the shunt tube 6 to move, and when the shunt tube 6 moves upward to the top convex edge abutting against the sealing ring 7 in the second guide tube 5, the convex edge at the bottom of the shunt tube 6 will abut against the bottom of the sealing ring 7 in the first guide tube 3; at this time, the guide port 10 on the second guide tube 5 is closed. Between the shunt pipe 6 and the second guide pipe 5, the guide port 10 in the first guide pipe 3 will be exposed, and the spray liquid will flow down along the inside of the shunt pipe 6 from the guide port 10 on the first guide pipe 3, and a group of spray pipes 1 located below will be activated, and the spray pipe 1 above will be in a sealed state and stop working; when the adjusting sleeve 4 is rotated counterclockwise, the shunt pipe 6 is driven to move downward, the bottom of the shunt pipe 6 abuts against the bottom of the first guide pipe 3, and the convex edge at the top abuts against the top of the sealing ring 7 in the first guide pipe 3, and the guide port 10 in the first guide pipe 3 is sealed at this time; the spray liquid is discharged from the guide port 10 in the second guide pipe 5. Since the shunt pipe 6 is a hollow structure, the shunt pipe 6 will be filled with spray liquid at this time. Since the length of the shunt pipe 6 is not too large, the internal liquid can be ignored and will not affect the spraying of the spray pipe 1 above.

[0023] Furthermore, the limiting guide is used to limit the position of the shunt pipe 6 to prevent the shunt pipe 6 from rotating synchronously with the rotation of the adjustment sleeve 4; specifically, the limiting guide includes a limiting guide rod 11 arranged on the shunt pipe 6; a guide hole is provided through the sealing ring 7 in the first guide pipe 3, and the limiting guide rod 11 is slidably located in the guide hole.
