[0040] As a more preferred embodiment, the slide rail 11 is fixedly connected to the inner top of the greenhouse, or can be detachably connected to the inner top of the greenhouse. The length of the slide rail 11 can be determined according to the length of the greenhouse. Specifically, the slide rail 11 can be welded on the frame of the inner top of the greenhouse, or the slide rail 11 can be connected and fixed by means of bolts and the like, so that the whole slide rail 11 can be detached for use in the frame structures of various greenhouses, and can be combined with various greenhouses.

The water spraying pipe 13 can pass through the bottom of the fixing plate 125 in the transverse direction. The other suspension member 126 is arranged on the bottom of the fixing plate 125 in the axial direction of the water conveying hose 14 and close to the pipe winding assembly 2, so as to form a space for the water conveying hose 14 to pass through.
