[0044] See also Figure 1-7 , an environmentally friendly sprinkler irrigation device for municipal garden construction, comprising:

[0045] A water supply main line 1, a water spraying line 2 is arranged in the water supply main line 1, the water supply main line 1 and the water spraying line 2 are connected, and a plurality of water spraying holes 3 are arranged circumferentially on the water spraying line 2, wherein the water supply main line 1 is connected to a tap water pipeline to access a water source, and water is sprayed to the surroundings through the plurality of water spraying holes 3 of the water spraying line 2 connected thereto for irrigation;

[0046] A telescopic guide structure is provided between the main water supply line 1 and the water spray line 2 to guide the water spray line 2 to slide in the main water supply line 1 without being separated from the main water supply line 1, and the upper end of the water spray line 2 extends from the upper end of the main water supply line 1. When the upper end of the water spray line 2 extends from the upper end of the main water supply line 1, a plurality of water spray holes 3 are exposed for spray irrigation. When the water spray line 2 is retracted into the main water supply line 1, the plurality of water spray holes 3 are hidden in the main water supply line 1 to avoid blockage and the like.

[0047] A water volume regulating chamber structure, which is arranged inside the water spray pipe 2 and connected to the main water supply pipe 1, is used to adjust the water outlet aperture at the water spray hole 3, thereby being able to adjust the water outlet efficiency at the water spray hole 3, control the irrigation water volume in the same time, and also be able to form atomized irrigation when the aperture within the range is the smallest, and form a flood irrigation form when the aperture is the largest; and

[0048] The directional water diversion mechanism is detachably arranged on the water spray pipeline 2 to direct water to one direction for spray irrigation, thereby achieving a precise irrigation effect.

[0049] Furthermore, the telescopic guide structure includes:

[0050] A first guide chute 4, which is arranged on the inner wall of the main water supply pipe 1; and

[0051] The first guide sliding block 5 is arranged at the lower end of the outer surface of the water spraying pipeline 2 and slides inside the first guide sliding groove 4 .

[0052] Specifically, the first guide sliding block 5 slides in the first guide sliding groove 4 and cannot escape from the first guide sliding groove 4 , so as to limit the sliding travel of the water spray pipeline 2 in the main water supply pipeline 1 .

[0053] Furthermore, the top end of the water spray pipe 2 is sealed and the bottom end is open so that the open end is connected to the main water supply pipe 1, so that after the water enters the water spray pipe 2, it can only be sprayed out from the multiple water spray holes 3 thereof.

[0054] Furthermore, the water volume regulating chamber structure includes:

[0055] A water guide cavity 6 is disposed in the water spray pipeline 2 and slides in the water spray pipeline 2, and the lower end of the water guide cavity 6 is open to communicate with the main water supply pipeline 1;

[0056] The second guide chutes 7 are arranged on the inner wall of the water spray pipe 2. The second guide chutes 7 are multiple groups distributed circumferentially on the inner wall of the water spray pipe 2 and are arranged one by one corresponding to the multiple water spray holes 3. The second guide chutes 7 are connected to the corresponding water spray holes 3; and

[0057] A second guide slider 8 is arranged at the lower end of the outer surface of the water spray pipe 2 and slides inside the second guide slot 7. The second guide sliders 8 are multiple groups with the same structure and are arranged one by one correspondingly between the multiple groups of second guide slots 7;

[0058] A triangular adjustment hole 9, which is provided on the second guide slider 8 and communicates with the interior of the water-conducting cavity 6, and the triangular adjustment hole 9 is extended and stretched along the axial direction of the water-conducting cavity 6; and

[0059] The regulating mechanism is arranged between the water-conducting cavity 6 and the water-spraying pipeline 2 to regulate the relative sliding movement between the water-conducting cavity 6 and the water-spraying pipeline 2 in the axial direction.

[0060] Specifically, driven by the adjusting mechanism, the water-conducting cavity 6 and the water spray pipe 2 slide relative to each other in the axial direction, thereby adjusting the position of the water spray hole 3 relative to the triangular adjusting hole 9 in the axial direction. Because the transverse width of the triangular adjusting hole 9 changes linearly in the axial direction, during the axial movement of the triangular adjusting hole 9 relative to the water spray hole 3, the relative apertures of the two change to achieve aperture adjustment.

[0061] Furthermore, the outer wall of the second guide slider 8 and the inner wall of the second guide slot 7 are tightly fitted and slide relative to each other. The second guide slider 8 slides inside the second guide slot 7 and cannot rotate relative to each other. The outer wall of the second guide slider 8 and the inner wall of the second guide slot 7 are tightly fitted to ensure the sealing effect, and water only flows out from the triangular adjustment hole 9 and the water spray hole 3.

[0063] A threaded hole 10 is provided at the center of the top end of the water spray pipe 2; and

[0064] The threaded rod 11 is inserted into the threaded hole 10 and threadedly matched with the threaded hole 10. One end of the threaded rod 11 extending into the water spray pipe 2 is connected to the upper end of the water guide cavity 6. The threaded rod 11 and the water guide cavity 6 are rotatably connected via a bearing.

[0065] Specifically, during use, the threaded rod 11 is rotated to engage with the threaded hole 10 , thereby driving the water-conducting cavity 6 to move axially.

[0066] Furthermore, the directional water diversion mechanism includes:

[0067] An external thread 12 formed on the outer surface of the water spray pipe 2;

[0068] The internal threaded sleeve 13 is sealed at the top and open at the bottom and can be sleeved on the water spray pipe 2. The internal threaded sleeve 13 has internal threads to be threadedly matched with the external threads 12 of the water spray pipe 2.

[0069] The outer extension cavity 14 is an annular inner cavity and is formed on the circumferential surface of the internal threaded sleeve 13 to form a cavity with the water spray pipe 2. The position of the outer extension cavity 14 is arranged corresponding to the position of the water spray hole 3;

[0070] An external connector 15 connected to the outer surface of the internal threaded sleeve 13 and communicating with the external extension cavity 14; and

[0071] One end of the water supply pipe 16 is connected to the external joint 15 , and a plurality of drainage holes 17 are provided on the water supply pipe 16 .

[0072] Specifically, when directional water diversion is required, the water spray pipe 2 is extended, the internal threaded sleeve 13 is screwed on the water spray pipe 2, and the water diversion pipe 16 is connected to the external extension cavity 14 by connecting to the external joint 15, so that water is diverted and sprayed at multiple drainage holes 17 under high pressure for irrigation. Therefore, the length of the water diversion pipe 16 is designed according to specific needs, and the connection between the external joint 15 and the water diversion pipe 16 can be connected by threaded connection or by sleeve tightening.

[0073] To sum up, the device can adjust the water output efficiency during sprinkler irrigation according to needs, achieve the switching of irrigation modes between atomization irrigation and flooding irrigation, further improve the utilization rate of water resources, and use the directional water diversion mechanism to divert water in the specified direction for irrigation, so as to achieve the effect of precise irrigation, further improve the utilization rate of water resources, improve the convenience of irrigation in municipal garden construction, and better achieve environmental protection effects.

[0074] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
