[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0024] Please see the attached Figure 1-Figure 5 The utility model discloses a novel telescopic automatically adjustable sprinkler head, comprising a sprinkler head body 1 and a water inlet pipe 5, a mounting shell 2 and a telescopic drive assembly 4, wherein:

[0025] The nozzle body 1 is connected to the water inlet pipe 5 through a pipe;

[0026] The upper end of the mounting shell 2 is provided with a self-sealing component 3 that seals the top of the mounting shell 2, and the nozzle body 1 is movably connected in the mounting shell 2;

[0027] The telescopic drive assembly 4 includes a lifting cylinder 41 , a transmission plate 42 is installed at the output end of the lifting cylinder 41 , and a transmission column 43 extending into the mounting shell 2 is installed on the transmission plate 42 , and the transmission column 43 is fixedly connected to the nozzle body 1 .

[0028] It should be noted that the lifting cylinder 41 can be controlled by a PLC programming controller for timed automatic control, or it can be controlled manually by connecting to a terminal control device. Both are existing conventional control methods, so no further details will be given.

[0029] Please refer to the attached Figure 3 、 Figure 4 The nozzle body 1 is equipped with a retractable hose 12, and the nozzle body 1 is connected to the water inlet pipe 5 through the hose 12. Specifically, the hose 12 can be extended or shortened as the nozzle body 1 is raised or lowered, without affecting the connection between the nozzle body 1 and the water inlet pipe 5.

[0030] Please refer to the attached Figure 2The self-sealing component 3 includes a symmetrical cover plate 31, which is rotatably connected to the upper end surface of the cover plate 31 through a pin and cooperates with the cover plate 31. The cover plates 31 cooperate with each other. The self-sealing component 3 also includes a torsion spring 32 provided on the side end of the pin on the cover plate 31 and connected to the pin. The torsion spring 32 is a rolled leaf torsion spring 32;

[0031] In this embodiment, the cover plate 31 can be pushed open when the nozzle body 1 is extended, which does not affect the water spraying of the nozzle body 1. After the nozzle body 1 is retracted, the torsion spring 32 can drive the cover plate 31 to rotate and automatically reset the closed mounting shell 2 to block and protect the water outlet of the nozzle body 1.

[0032] Please refer to the attached Figure 2 、 Figure 3 The inner wall of the mounting shell 2 is provided with a plurality of guide grooves 23, and the outer wall of the nozzle body 1 is provided with a plurality of limiting slide rods 11 which are slidably connected with the guide grooves 23. The ends of the limiting slide rods 11 are spherical. Specifically, by sliding the limiting slide rods 11 in the guide grooves 23, the nozzle body 1 can be kept stably lifted and lowered vertically in the mounting shell 2, thereby preventing the nozzle body 1 from tilting and getting stuck during lifting.

[0033] Please refer to the attached Figure 2 、 Figure 4 The bottom of the mounting shell 2 is provided with an assembly flange 21 and a mounting flange 22, and the assembly flange 21 cooperates with the mounting flange 22. The assembly flange 21 is fixed to the bottom of the mounting shell 2, and a sealing ring 211 is installed at the bottom of the assembly flange 21. The upper end of the mounting flange 22 is provided with a sealing groove 221 that cooperates with the sealing ring 211. Specifically, the mounting shell 2 can be disassembled and assembled through the assembly flange 21, which is convenient for quick replacement of the damaged mounting shell 2 or the damaged cover plate 31. The sealing ring 211 and the sealing groove 221 can prevent water from seeping from the assembly flange 21 and the mounting flange 22 to the bottom to corrode the cylinder. Example 2

[0034] Based on the above embodiment 1, please refer to the attached Figure 3 、 Figure 5 The transmission plate 42 is installed with a linkage plate 421 with holes. When a plurality of parallel arranged nozzle bodies 1 are provided, a linkage rod 422 is installed through the hole in the linkage plate 421, so that the linkage rod 422 can connect the linkage plates 421 on all nozzle bodies 1 together. Only by installing the lifting cylinder 41 under the transmission plate 42 at the bottom of the nozzle body 1 at both ends can all the nozzle bodies 1 connected by the linkage rod 422 be driven to rise and fall.

[0035] The working principle and use process of the utility model are as follows: when the nozzle is used, the lifting cylinder 41 is started to drive the transmission plate 42 to move upward, and the transmission plate 42 drives the nozzle body 1 to move upward through the transmission column 43. The nozzle body 1 moves vertically upward along the mounting shell 2 under the action of the limit slide 11. As the nozzle body 1 rises, the nozzle body 1 extends out of the mounting shell 2 and pushes the cover plate 31 open. When the nozzle body 1 is completely extended out of the mounting shell 2, the lifting cylinder 41 stops, and the cover plate 31 rotates and is pushed to both sides of the nozzle body 1 without covering it. Block the water outlet of the nozzle body 1. At this time, the nozzle body 1 can operate to perform a water spraying performance. After the performance, the lifting cylinder 41 starts to drive the transmission plate 42 to move downward. The transmission plate 42 drives the nozzle body 1 to move downward and retract into the mounting shell 2 through the transmission column 43. When the nozzle body 1 is completely retracted into the mounting shell 2, the cover plate 31 rotates to close the top of the mounting shell 2 under the action of the torsion spring 32. At this time, the nozzle body 1 is located in the mounting shell 2 and is wrapped by the mounting shell 2 and the cover plate 31, and is not affected by external debris.
