[0011] Compared with related technologies, the modular green lawn drainage device for easy irrigation provided by this utility model has the following beneficial effects:

[0012] 1. By setting up a modular base box, a lawn support plate, and a drainage baffle, the filter holes on the lawn support plate can quickly drain excess water to prevent water accumulation. The filter material such as activated carbon filled between the drainage baffle and the lawn support plate can filter and purify the seeping water, which then flows into the modular base box for storage through the filter holes of the drainage baffle. This not only ensures smooth drainage but also improves the quality of recycled water, facilitating subsequent recycling.

[0013] 2. The system features a lifting mechanism that allows for adjustable spray head height. A servo motor drives a lead screw via a transmission bevel gear and a driven bevel gear, causing the lifting rod to rise and fall stably under the limiting action of the fixed frame. This changes the height of the spray head to accommodate the irrigation needs of lawns at different growth heights, ensuring irrigation coverage and uniformity. A water pump draws water stored in the module's bottom box and delivers it to the spray head via a water hose, achieving water recycling and reducing water waste.

[0014] 3. By installing lawn support plates, when problems occur in a part of the lawn, the problem can be easily moved and replaced using the hanging rings on the lawn support plates, reducing maintenance costs and avoiding impact on the overall lawn landscape. Attached Figure Description

[0022] In the specific implementation process, lifting rings 11 are fixedly connected to the upper surfaces of both sides of the lawn support plate 2 to facilitate the handling and installation of the lawn support plate 2. A retaining net 12 is fixedly connected to the upper surface of the lawn support plate 2 to fix the soil when the lawn support plate 2 is filled with soil, so as to prevent the soil from collapsing from the lawn support plate 2. After the soil is filled, the lawn can be laid. The upper surface of the lawn support plate 2 has drainage holes to facilitate the drainage of excess water from the lawn support plate 2. The upper surface of the lawn support plate 2 has fixing holes. A receiving tube 13 is fixedly connected to the inner wall of the fixing hole on the upper surface of the lawn support plate 2 to receive the upper end of the lifting rod 7, which plays a guiding and protective role for the lifting rod 7. The upper end of the receiving tube 13 is higher than the soil filled by the lawn support plate 2.

[0023] The upper surface of the drainage baffle 3 is provided with filter holes for further filtering of seeping water, while allowing water to flow to the bottom of the module base box 1. Filter materials such as activated carbon are filled between the drainage baffle 3 and the lawn support plate 2. The upper surface of the drainage baffle 3 is provided with fixing holes, and the inner wall of the fixing holes on the upper surface of the drainage baffle 3 is also fixedly connected with a receiving tube 13, which cooperates with the receiving tube 13 on the lawn support plate 2 to guide and protect the lifting rod 7.

[0024] The lower surface of the base 5 is fixedly connected to the bottom of the module base box 1. The base 5 has a cavity inside and a through hole on its upper surface. The through hole on the upper surface of the base 5 is connected to the cavity inside the base 5.

[0025] The upper surface of the fixed frame 6 has limit grooves on both sides of the limit hole. The lower end of the lifting rod 7 is fixedly connected to the limit grooves on both sides of the limit hole, which cooperate with the limit grooves on the fixed frame 6 to prevent the lifting rod 7 from rotating during the lifting process and to ensure the stability of the lifting direction. The limit strips 19 on both sides of the lower end of the lifting rod 7 are slidably connected to the limit grooves on both sides of the limit hole on the upper surface of the fixed frame 6. The lower end of the lifting rod 7 has a threaded hole, which is connected to the inside of the tube cavity of the lifting rod 7. The upper end of the lifting rod 7 is fixedly connected to a spray head 14 for spraying water evenly onto the lawn to achieve the irrigation function. The upper end of the lifting rod 7 has a fixed cavity, and the water supply hose 10 is inserted into the fixed cavity at the upper end of the lifting rod 7. The upper end of the water supply hose 10 is fixedly connected to the lower end of the spray head 14, and the water supply hose 10 is connected to the spray head 14.

[0026] The lead screw 8 is threaded into the threaded hole at the lower end of the lifting rod 7. The lead screw 8 is rotatably connected to the through hole on the upper surface of the base 5. A limit piece 15 is fixedly connected to the upper end of the lead screw 8 to limit the rising height of the lifting rod 7 and prevent it from detaching from the lead screw 8. The lower end of the lead screw 8 extends through the through hole on the upper surface of the base 5 into the cavity of the base 5. A driven bevel gear 16 is fixedly connected to the lower end of the lead screw 8, engaging with a transmission bevel gear 17 to transmit power from the servo motor 18 to the lead screw 8, causing it to rotate. The transmission bevel gear 17 meshes below the driven bevel gear 16, driving the servo motor 18 to rotate. The rotational motion of screw 8 is transmitted to the driven bevel gear 16. A servo motor 18 is provided at one end of the transmission bevel gear 17 to provide power for the rotation of screw 8. The rotational state of screw 8 is controlled by controlling its start, stop and direction. The power output end of the servo motor 18 is fixedly connected to one end of the transmission bevel gear 17. The servo motor 18 is fixedly connected to the bottom of the cavity of the base 5. The servo motor 18 is electrically connected to an external power supply and an external PLC controller switch. The start and stop of the servo motor 18 are controlled by the external PLC controller switch. The PLC controller switch is a commonly used technology and will not be described in detail here.

[0027] The working principle of this utility model is as follows: The module base box 1 serves as a basic support to accommodate various components and store water. The lawn support plate 2 supports the soil and lawn. The retaining net 12 fixes the soil to prevent collapse. Excess water seeps down through the filter holes of the lawn support plate 2 to the drainage baffle 3. The filter holes on the drainage baffle 3, together with the activated carbon and other filter materials between it and the lawn support plate 2, further filter the water. The filtered water flows into the module base box 1 for storage. During irrigation, the water pump 9 starts to draw water stored in the module base box 1 and delivers it to the spray head 14 through the water delivery hose 10. At the same time, the servo motor 18 starts under the control of the external PLC controller, and its power output drives the transmission bevel gear. When wheel 17 rotates, the transmission bevel gear 17 meshes and drives the driven bevel gear 16 to rotate. The driven bevel gear 16 drives the lead screw 8 to rotate in the through hole of the base 5. Since the lifting rod 7 is threadedly connected to the lead screw 8 through the lower threaded hole and its two side limit strips 19 slide in the limit groove of the fixed frame 6 and are restricted from rotating, the rotation of the lead screw 8 causes the lifting rod 7 to move up and down along the limit hole of the fixed frame 6, thereby driving the spray head 14 to rise and fall. The upper end of the lifting rod 7 moves in the receiving tube 13 of the lawn support plate 2 and the drainage partition 3. The limit plate 15 prevents the lifting rod 7 from falling off the lead screw 8. Finally, the spray head 14 sprays water evenly onto the lawn to achieve irrigation. The lifting ring 11 facilitates the handling and installation of the lawn support plate 2.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
