[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: See Figures 1 to 3The utility model provides an adjustable irrigation device, including a three-way pipe 1, the left and right ends of the three-way pipe 1 are fixedly connected with a water supply pipe 2, the top of the three-way pipe 1 is fixedly connected with a fixed pipe 3, the top of the fixed pipe 3 is fixedly connected with an end cover 8, a lifting pipe 4 that movably penetrates the end cover 8 is slidably sleeved in the fixed pipe 3, and a spray pipe 5 is rotatably connected to the top of the lifting pipe 4, and the spray pipe 5 is a cross-shaped atomizing nozzle. The bottom inner wall of the lifting pipe 4 is fixedly connected with a circular ring plate 6, the bottom outer wall of the lifting pipe 4 is fixedly sleeved with a sealing ring 7, the end cover 8 is provided with a threaded hole 9 that penetrates up and down, the inner thread of the threaded hole 9 is matched with an adjusting block 10, the lower surface of the adjusting block 10 is fixedly connected with a pressure rod 11, the outer wall of the lifting pipe 4 is fixedly sleeved with a limit block 12, and the upper surface of the limit block 12 is aligned with the lower surface of the pressure rod 11.

[0020] Among them, the water supply pipe 2 is connected to the municipal water pipe, and a pressure pump is provided between the water supply pipe 2 and the municipal water pipe, which can pressurize the water pressure in the water supply pipe 2 to 0.35-0.40MPa. In the utility model, the lifting pipe 4 and the spray pipe 5 are both made of lightweight PVC pipes. The water pressure in the water supply pipe 2 is sufficient to overcome the friction between the fixed pipe 3 and the sealing ring 7, the friction between the lifting pipe 4 and the sealing ring 16, and the load from the lifting pipe 4 and the spray pipe 5 to lift the lifting pipe 4 to a certain height.

[0021] When the water supply pipe 2 is connected to the municipal water pipe, water flows from the tee pipe 1 into the fixed pipe 3, part of the water flows into the lifting pipe 4 from the circular hole of the circular plate 6, and part of the water flows under the action of water pressure to push the circular plate 6 up, so as to lift the lifting pipe 4 to a certain height. The fixed pipe 3 and the lifting pipe 4 form a telescopic pipeline, which can change the horizontal height of the spray pipe 5, thereby expanding the spray range of the spray pipe 5. After the lifting pipe 4 is lifted to a certain height, the limit block 12 abuts against the pressure rod 11, and the lifting pipe 4 stops rising. When the water supply pipe 2 is closed, the water pressure is lost, and the lifting pipe 4 automatically falls back under the action of gravity. The lifting pipe 4 can be automatically raised and lowered for easy storage.

[0022] On the basis of the above embodiment, the sealing ring 7 in this embodiment is an inverted bowl-shaped structure, and an annular groove 17 is provided on the lower surface of the sealing ring 7, and the positive longitudinal section of the annular groove 17 is an inverted V-shaped. When the water flows into the fixed pipe 3 from the tee pipe 1, part of the water flows hit the sealing ring 7, causing the annular groove 17 to expand, so that the outer edge of the sealing ring 7 is in full contact with the inner wall of the fixed pipe 3, thereby improving the sealing effect between the sealing ring 7 and the fixed pipe 3 and avoiding leakage.

[0023] On the basis of the above embodiment, in this embodiment, two annular holes 15 are provided on the inner wall of the cover 8, and the two annular holes 15 are arranged at intervals in the upper and lower parts. A sealing ring 16 is fixed in the annular hole 15, and the sealing ring 16 is movably connected with the lifting tube 4. The sealing ring 16 and the sealing ring 7 form a double sealing structure to improve the sealing between the fixed tube 3 and the lifting tube 4. The sealing ring 16 is an O-type polytetrafluoroethylene sealing ring, which has a low friction coefficient and good wear resistance, and can reduce the friction force on the lifting tube 4 during the sealing process.

[0024] On the basis of the above embodiment, in this embodiment, a cross slot, a slotted slot, or a hexagonal slot is provided on the upper surface of the adjusting block 10. The utility model can rotate the adjusting block 10 by a corresponding screwdriver to adjust the horizontal height of the pressure rod 11, thereby restricting the maximum lifting height of the lifting pipe 4, avoiding the horizontal height of the spray pipe 5 from being too high, and making the spray range of the spray pipe 5 within a certain range.

[0025] On the basis of the above-mentioned embodiment, in this embodiment, a pipe sleeve 13 is fixedly connected to the upper surface of the end cover 8 and located outside the lifting tube 4. The inner diameter of the pipe sleeve 13 is equal to the outer diameter of the lifting tube 4. An adjusting bolt 14 for tightening or loosening the lifting tube 4 is provided on the pipe sleeve 13. The adjusting bolt 14 is a butterfly bolt. The screw section of the adjusting bolt 14 is threadedly connected to the pipe sleeve 13 and is pressed and abutted against the outer wall of the lifting tube 4. The friction force generated by the pressing of the adjusting bolt 14 and the outer wall of the lifting tube 4 can fix the lifting tube 4 at a certain height. The fixed pipe 3 and the lifting tube 4 form a fixed pipeline.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
