Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Specifically, the clamping mechanism 1 and the reciprocating movement mechanism 10 are used in cooperation. The specific working principle is as follows:

[0042] When the first motor 2 starts and drives the turntable 3 to rotate, the telescopic rod 7 clamps the lamp by moving inward from all around in cooperation with the clamping plate 8, thereby realizing the limit clamping of the lamp.

Moreover, under the action of screw rotation, it can drive the spraying assembly 14 to move upward synchronously. Since a torsion spring 13 is provided on the central shaft, under the action of the elastic restoring force, the lead screw shaft 12 rotates in the opposite direction and drives the spraying assembly 14 to move downward. In this way, the spraying assembly 14 can perform corresponding rain - proof operations on lamps of different heights.

[0043] A clamping mechanism 1 is provided. After the first motor 2 is started, it can drive the turntable 3 to rotate. With the rotational connection of the swing rod 5, the telescopic rod 7 drives the clamping plate 8 to fix the lamp in a surrounding clamping and limiting manner. During the movement of the telescopic rod 7, it can drive the lead screw shaft 12 on the central shaft to rotate through the meshing transmission of gears. Under the action of screw transmission, it further drives the up and down movement of the spraying assembly 14, so that the spraying work can be adaptively carried out on lamps of different heights. In addition, a torsion spring 13 is provided on the central shaft, which can help the lead screw shaft 12 to rotate in the reverse direction, and then automatically adjust the reverse movement of the spraying assembly 14. Cooperating with the telescopic rod 7 on the gear plate 9, it will not affect the normal positioning and clamping work of the clamping plate 8, ensuring the stability of the device operation and strong practicability.

Both ends of the cover 30 are movably supported and connected to the ring 17 by the bent rod 31, and an annular movable opening 32 connected to the bent rod 31 is formed at the outer wall edge of the ring 17.

[0048] A support mechanism is provided. The annular movable opening 32 on the annular ring 17 can, on the one hand, support and connect the cover body 30 on the bending rod 31, and on the other hand, prevent the bending rod 31 from deviating in position during rotation. At the same time, the top plate 16 and the support portion 38 at the bottom end of the annular ring 17 can further support and connect between the structural members, ensuring the stability of the connection of the structural members. The shape design of the annular ring 17 facilitates the normal passage of the lamp, thus ensuring the normal spraying operation of the spraying assembly 14.

[0049] Reference Figure 2 、 Figure 7 and Figure 8 ,The diversion groove inside the third slider 24 can transfer water to the spray pipe 28 through the rotating rod 27. The corrugated hose 26 is installed on the third slider 24 by means of threaded connection, which can facilitate the installation work of the structural members.

Support portions 38 are provided on both sides of the bottom ends of the top plate 16 and the annular ring 17 and are connected to the top plate 16 and the annular ring 17 by means of locking and fixing with positioning pins.

The second motor 18 drives the cover 30 on the multi-pass pipe 20 to rotate through the connecting member 19, and then drives the spray pipe 29 on the spray pipe 28 to rotate together. In this way, through the rotating spray method, the lamp is subjected to all-round rain shower work, avoiding the phenomenon of rain shower omission.

The hollow guide sleeve 33 on the connecting member 19 can provide corresponding moving space for the liquid flow. At the same time, the fixing ring 36 on the guide sleeve 33 can be connected to the output shaft of the second motor 18 and the multi-pass pipe 20, which can prevent the output shaft of the second motor 18 and the multi-pass pipe 20 from deviating in position during rotation. The structural member is convenient for disassembly, which is beneficial to personnel operation and improves work efficiency. The plug 37 on the output shaft of the second motor 18 cooperates with the slot, which can effectively transmit the power to the multi-pass pipe 20, thereby ensuring the normal rotation of the structural member. In this way, the spray component 14 can perform adaptive rotating spray work at different positions, greatly improving the applicability of the device.
