[0032] Furthermore, a protection mechanism is installed on the surface of the control box 16. The protection mechanism includes a protection chamber 3, which is installed on the outer surface of the control box 16. An extension plate 31 and an installation chamber 32 are fixedly connected to the surface of the protection chamber 3. Through holes 33 are formed on the surface of the installation chamber 32. A support spring 34 and a limit plate 35 are movably connected to the inner surface of the installation chamber 32. A clamping block 36 is fixedly connected to the surface of the limit plate 35.

Moreover, through the clamping of the clamping block 36 and the clamping hole 38, the installed protection chamber 3 can be limited and fixed.

[0035] Working principle: When the position of the nozzle 14 needs to be adjusted, first pull the support frame 12 upward so that it slides along the inner surface of the sleeve 2. When it moves to the appropriate position, the jacking hole 26 and the adjustment hole 25 at the corresponding position are aligned. At this time, insert the bolt 27 into the adjustment hole 25 and the jacking hole 26, and connect the second nut 28 to the bolt 27 through the thread and abut it against the surface of the sleeve 2 to complete the adjustment of the height of the nozzle 14. When the sleeve 2 needs to be replaced, loosen and remove the first nut 24 at the corresponding position through the thread, and pull the sleeve 2 so that the installation block 21 is removed along the screw 23 through the installation hole 22 for replacement.

[0036] When using the sprinkler, first cover the protection bin 3 on the outer surface of the control box 16 and place it between two groups of mounting plates 37. At the same time, press the clamping block 36 into the mounting bin 32, so that the limiting plate 35 slides along the inner surface of the through hole 33, and the support spring 34 is in a compressed state. When the protection bin 3 abuts against the moving frame 1, at this time, under the action of the supporting force applied by the support spring 34, the limiting plate 35 abuts against the inner surface of the mounting bin 32, and the clamping block 36 passes through the through hole 33 and engages with the engaging hole 38, thereby completing the installation of the protection bin 3 to achieve the protection of the control box 16.
