A support block 13 is welded to one side of the sliding sleeve 10. The free end of the wire rope 20 passes around the pulley 11 and is fixedly connected to the support block 13. Adjusting rods 15 are installed at both ends of the support block 13. A spray pipe 16 is fixedly connected to the outside of the adjusting rod 15. The protective sleeve 19 is placed on the outside of the lifting slide rod to bind the wire rope and the water pipe.
[0016] It should be noted that in this embodiment, one end of the water pipe is connected to the middle of the spray pipe 16. An appropriate number of extension rods 5 are selected according to the required height. The extension rods 5 are inserted and fixed after being connected at the top and bottom. The top rod 12 is fixedly installed on the top of the uppermost extension rod 5. According to the required spraying height, the winding shaft 3 is driven to wind up through the transmission box 4. Under the cooperation of the wire rope 20 and the pulley 11, the wire rope 20 pulls the sliding sleeve 10 towards the pulley 11, thereby adjusting the height of the adjusting rod 15 and the spray pipe 16. This allows the spray coverage to be flexibly adjusted as needed, ensuring the flexibility of the equipment.
[0017] In one embodiment, the bottom of the support column 2 is rotatably connected to the base 1, and the middle of the base 1 is threaded with a bolt for fixing the support column 2.
[0018] It should be noted that in this embodiment, the four corners of the base 1 are provided with through holes for fixing the base 1 to the ground by means of fasteners. The support column 2 is rotatably installed on the top of the base 1. The angle of the support column 2 can be rotated to adjust the spray direction of the spray pipe 16. After the adjustment is completed, the support column 2 is connected to the base 1 by bolts to press and fix it.
[0019] In one embodiment, the transmission box 4 is a worm gear transmission box, the output end of the transmission box 4 is connected to the winding shaft 3, and the input end of the transmission box 4 is fixedly connected to a drive handwheel.
[0020] It should be noted that in this embodiment, the worm gear inside the transmission box 4 is driven to rotate by the drive handwheel, the worm gear drives the worm wheel to rotate, and the worm wheel drives the winding shaft 3 to rotate. In this way, the wire rope 20 is wound up by the winding shaft 3. The self-locking of the worm wheel and worm gear prevents the sliding sleeve 10 from reversing under the action of gravity.
[0021] In one embodiment, the extension rod 5 has a mounting hole 8 at its top, a mounting post 9 that mates with the mounting hole 8 is fixedly connected to the bottom of the extension rod 5, a limiting groove 6 is provided on one side of the extension rod 5, a protrusion that mates with the limiting groove 6 is fixedly connected inside the sliding sleeve 10, and a countersunk hole 7 is provided at one end of the limiting groove 6 near the mounting hole 8.
[0022] It should be noted that in this embodiment, the mounting post 9 at one end of the extension rod 5 is inserted into the mounting hole 8 at the end of the other extension rod 5. During installation, the limiting grooves 6 in the middle of the two extension rods 5 are aligned. The limiting grooves 6 can limit the sliding sleeve 10, ensuring that the sliding sleeve 10 can move vertically up and down. After the extension rods 5 are connected and installed, the screws are installed inside the countersunk hole 7, so that the screws pass through the mounting post 9, thereby fixing and splicing the extension rods 5 with screws.
[0023] In one embodiment, one end of the adjusting rod 15 is fixedly connected to a disc 17, the disc 17 is rotatably connected to the support rod 14, and one end of the support rod 14 is threadedly connected to a fixing bolt 18 for pressing and fixing the disc 17.
[0024] It should be noted that in this embodiment, multiple limiting holes are equidistantly provided on the top of the disc 17. The adjusting rod 15 is rotated at one end of the support rod 14. After rotating to a suitable angle, it is engaged with the bottom disc 17 by fixing bolt 18, thereby fixing the included angle between the adjusting rod 15 and the support rod 14. The support rod 14 is rotatably installed in the middle of the support block 13. The middle of the support block 13 is threaded with a bolt for fixing the angle of the support rod 14. The elevation angle of the adjusting rod 15 can be adjusted by the bolt.
[0025] In one embodiment, the protective sleeve 19 is a corrugated tube made of rubber, and the sliding sleeve 10 and the support column 2 are both threaded to the end of the protective sleeve 19.
[0026] It should be noted that in this embodiment, both ends of the protective sleeve 19 are rotatably equipped with connecting rings with internal threads. The connecting rings are connected to the sliding sleeve 10 and the support column 2 respectively. By raising and lowering the sliding sleeve 10, the protective sleeve 19 is pulled up and stretched. In this way, the water pipe and steel wire rope 20 connected to the outside of the bottom extension rod 5 and the spray pipe 16 are wrapped inside the protective sleeve 19 to prevent the water pipe and steel wire rope 20 from swinging under the action of wind during use.
