DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the present utility model in detail with reference to the drawings.

[0017] Embodiment: An improved telescopic water outlet pile, as Figure 1 and Figure 2 shown, includes a fixed pipe 1 and a telescopic movable pipe 2 movably connected to the fixed pipe 1. A pipe joint 3 is threadedly connected to the bottom of the fixed pipe 1. The irrigation user realizes the connection between the fixed pipe 1 and the upper telescopic movable pipe 2 and the water outlet of the underground pre-buried water delivery pipe network through the pipe joint 3, so as to facilitate the telescopic adjustment of the telescopic movable pipe 2 under the actual agricultural irrigation operation conditions, and finally achieve the elongation of the telescopic movable pipe 2 under the irrigation demand and the pressing contraction of the telescopic movable pipe 2 in the state of land ploughing.

[0018] An auxiliary protection sleeve assembly is also provided on the fixed pipe 1, which can achieve synchronous assembly during the installation of the pipe joint 3 part and the embedded water conveyance pipeline, and form a protective support for the connection of the pipe joint 3 during the working process of the water outlet pile. The auxiliary protection sleeve assembly includes a locking sleeve 4 movably connected to the side wall of the fixed pipe 1 and a limiting sleeve 5 movably connected to the locking sleeve 4. A locking thread section 6 is provided on the side wall of the fixed pipe 1, and an internal thread 7 matching the locking thread section 6 is provided on the inner wall of the locking sleeve 4. The user can manually rotate and adjust the locking sleeve 4 to achieve a vertical position change. A force application chute 16 is provided on the outer wall of the locking sleeve 4 to facilitate the operator's force application and rotation.

[0019] A rotating ring edge 8 is further provided at one end of the locking sleeve 4 away from its threaded connection with the fixed pipe 1. An annular clamping groove 9 for rotatably sleeving the rotating ring edge 8 is provided at one end of the limiting sleeve 5 connected to the locking sleeve 4. That is, after the assembly of the pipe joint 3 part is completed, the operator manually rotates the locking sleeve 4, causing the locking sleeve 4 to feed downward and drive the downward movement of the limiting sleeve 5. An arc-shaped pipe clamping groove 10 (as Figure 3 shown) is provided at one end of the limiting sleeve 5 away from the annular clamping groove 9. As the locking sleeve 4 continues to feed, the operator can flexibly rotate the limiting sleeve 5 to keep the arc-shaped pipe clamping groove 10 aligned with the wall surface of the embedded water conveyance pipeline. After the alignment action is completed, tighten the locking sleeve 4 until the arc-shaped pipe clamping groove 10 is in close contact with the embedded water conveyance pipeline. An anti-slip and shock-absorbing gasket 15 is provided at the notch of the arc-shaped pipe clamping groove 10, which helps to improve the basic tightness between the limiting sleeve 5 and the pipe surface, and can also effectively absorb the pipeline impact and vibration during the water flow conveyance in the outlet pipe.

[0020] Considering the structural compactness between the limiting sleeve 5 and the water outlet pile part and enhancing the support stability strength of the auxiliary protection sleeve assembly, reinforcing ribs 11 are provided on the inner wall of the limiting sleeve 5, and a locking groove 12 for the vertical sliding of the reinforcing ribs 11 is provided on the outer wall of the pipe joint 3. That is, during the locking of the locking sleeve 4 and the alignment of the limiting sleeve 5 part, the operator synchronously aligns and inserts the limiting sleeve 5 with the pipe joint 3, thereby ensuring the tight locking of the limiting sleeve 5 with the water outlet pile in the state of being pressed against the embedded water conveyance pipeline and improving the support protection strength.

[0021] When the operator needs to disassemble and assemble the water outlet pile, it is necessary to first screw the locking sleeve 4 upward, drive the upward movement of the limiting sleeve 5, release its tight fit with the embedded water conveyance pipeline. At the same time, a limiting ring edge 13 is provided on the side wall of the fixed pipe 1, and an anti-detachment block 14 that cooperates with the limiting ring edge 13 is provided on the inner wall of the locking sleeve 4, which can prevent the operator from rotating upward excessively and causing the detachment of the locking sleeve 4, improving the reliability of use and the convenience of adjustment of the auxiliary protection sleeve assembly in the water outlet pile. And considering that the normal water outlet pile is buried underground, a dust-proof gasket 17 is provided at the end pipe orifice where the locking sleeve 4 cooperates with the limiting ring edge 13, which can reduce the infiltration of impurities such as soil and affect the working stability of the locking sleeve 4 and the limiting sleeve 5.

[0022] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
