a water spray component, which comprises a first water pipe 21, three second water pipes 22, a planetary gear 23 and a plurality of spray pipes 24, wherein one end of the first water pipe 21 is connected with an external water source, the other end is communicated with the water inlet hole, one end of each of the three second water pipes 22 is simultaneously communicated with the three water guide holes on the sliding cavity 14, the planetary gear 23 is positioned at one end of the connecting pipe 15 extending out of the vent pipe 1, the planetary gear 23 comprises a sun gear 231, three first gear rings 232 meshed with the sun gear 231 simultaneously, and second gear rings 233 meshed with the three first gear rings 232 simultaneously, the sun gear 231 is coaxially connected with the connecting pipe 15, the three first gear rings 232 are hollow and are respectively communicated with the other ends of the three second water pipes 22, the plurality of spray pipes 24 are respectively arranged on the inner side walls of the three first gear rings 232, one spray pipe 24 comprises a bent pipe 241 and a nozzle 242, the bent pipe 241 is attached to the inner side wall of the, one end of the bent pipe 241 is communicated with the inner side wall of the first gear ring 232, and the other end is communicated with the nozzle 242, and the opening of the nozzle 242 is far away from the center of the first gear ring 232.

When in use, after the fan 3 positioned outside the tunnel is started, the wind generated by the fan 3 is sent into the tunnel along the ventilation pipe 1. When wind reaches the end of the ventilation pipe 1 extending into the tunnel 2, the fan 16 starts to rotate under the influence of wind force, and since the fan 16 is disposed on the connection pipe 15 and the connection pipe 15 is rotatably connected to the sleeve pipe 11 fixed in the ventilation pipe 1 through the first bearing, the sleeve pipe 11 is fixed and the connection pipe 15 rotates. At this time, the sun gear 231 fixed to one end of the connection pipe 15 is also rotated accordingly, and since the sun gear 231 is engaged with the three first ring gears 232 and the three first ring gears 232 are engaged with the second ring gear 233, the rotation of the sun gear 231 causes the three first ring gears 232 to revolve around the sun gear 231 while rotating on their own axis.
