Description

Technical Field

[0001] This utility model relates to the field of greening engineering, and in particular to a greening irrigation sprinkler head adjustment device. Background Technology

[0002] Green space irrigation refers to the process of providing targeted and quantitative water supply to plant growth areas through artificial intervention techniques. Its essence lies in constructing a water resource regulation system that integrates pressure-driven delivery, intelligent sensing and monitoring, and precise morphological allocation, based on plant physiological water requirements, soil water retention characteristics, and dynamic climate changes. This system maintains healthy vegetation metabolism, restores soil ecological functions, and achieves efficient water resource utilization by simulating natural rainfall, optimizing root watering, or creating a humid microenvironment. Ultimately, it achieves comprehensive ecological benefits such as drought stress relief, soil salinity control, microclimate regulation, and biodiversity enhancement. Specific technical approaches include: implementing zoned irrigation through buried PE pipe networks and solenoid valve assemblies; dynamically adjusting irrigation thresholds using soil moisture sensors, weather stations, and evaporation models; employing pressure-compensated drippers to address terrain elevation differences; deploying a combination of rotating sprinklers and atomized micro-sprayers to address the different water requirements of various vegetation types; and integrating an IoT platform for remote start / stop, fault warning, and integrated water and fertilizer management.

[0003] In existing technologies, sprinkler heads, as core components of greening irrigation, simulate natural rainfall to ensure even water penetration into the soil, preventing localized waterlogging or drought, and are crucial for plant root growth and water absorption. However, current sprinkler heads on the market have significant shortcomings in angle adjustment. Some sprinkler heads have simple designs with fixed structures, and the spray angle is determined at the factory, lacking a dedicated adjustment mechanism. For example, early simple buried sprinkler heads are difficult to change after installation, making them unsuitable for the irrigation needs of different green areas. Other sprinkler heads, while possessing angle adjustment capabilities, have complex structures and rely on specific tools for operation. For instance, large greening sprinkler heads require special wrenches or screwdrivers for adjustment. Gardeners often find it difficult to adjust the sprinkler angle in practice because they don't carry the tools or lose them, greatly affecting irrigation efficiency and effectiveness. These problems cause inconvenience in adjusting the angle of sprinkler heads during greening irrigation. Utility Model Content

[0004] The main purpose of this utility model is to provide a greening irrigation sprinkler head adjustment device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A greening irrigation sprinkler head adjustment device includes a water supply pipe and a sprinkler head.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] like Figure 1 - Figure 5 As shown, a greening irrigation sprinkler head adjustment device includes a water supply pipe 1 and a sprinkler head 2. An adjustment mechanism 3 is provided between the water supply pipe 1 and the sprinkler head 2. The adjustment mechanism 3 includes a connecting pipe 6, a bearing 9, a rotating pipe 13, a worm gear 15, and a worm 17. The connecting pipe 6 is fixedly connected to the first external threaded joint 4 at the top of the water supply pipe 1 through the first internal thread 7 on its inner wall. The bearing 9 is fixedly connected to the outside of the sleeve 8 at the top of the connecting pipe 6. The rotating pipe 13 is sleeved on the outside of the bearing 9. The worm gear 15 is sleeved on the outer wall of the rotating pipe 13. The worm 17 is movably connected to the inside of the outer shell 10 of the connecting pipe 6 through rotating rods 18 at both ends and meshes with the worm gear 15. The sprinkler head 2 is fixedly connected to the top of the rotating pipe 13 through the second external threaded joint 5 at the bottom end.

[0022] like Figure 2 As shown, a first external threaded connector 4 is fixedly installed at the top of the water supply pipe 1, and the first external threaded connector 4 on the water supply pipe 1 provides an installation base for the connecting pipe 6.

[0023] like Figure 3 As shown, the inner wall of the connecting pipe 6 is provided with a first internal thread 7, and the first internal thread 7 is threaded together with the first external thread connector 4. The connecting pipe 6 can be threaded together with the first external thread connector 4 through the first internal thread 7, so that the adjusting mechanism 3 can be installed on the water supply pipe 1 for use.

[0024] like Figure 4 As shown, a sleeve 8 is fixedly installed at the top of the connecting pipe 6, and a housing 10 is fixedly installed on the outer wall of the connecting pipe 6. The connecting pipe 6, sleeve 8 and housing 10 are integrated. A bearing 9 is also fitted on the outer wall of the sleeve 8. The inner ring of the bearing 9 is fixedly installed with the outer wall of the sleeve 8. The bearing 9 provides a rotation base for the rotating pipe 13. A through hole 11 is opened on the top surface of the housing 10. The through hole 11 can ensure the normal rotation of the rotating pipe 13 passing through the housing 10. Rotation holes 12 are opened on the left and right side walls of the housing 10 respectively. The rotation holes 12 are used to cooperate with the rotation rod 18 to realize the rotation operation.

[0025] like Figure 4 and Figure 5As shown, the rotating tube 13 passes through the through hole 11 and is fixedly installed together with the outer ring of the bearing 9 in a sleeve manner. The top surface of the worm gear 15 is provided with a sleeve hole 16, and the worm gear 15 is fixedly installed on the outer wall of the rotating tube 13 through the sleeve hole 16 in a sleeve manner. Rotating rods 18 are fixedly installed at the left and right ends of the worm 17, and the rotating rods 18 are movably installed in the rotating hole 12. The worm 17 and the worm gear 15 are meshed together. A knob 19 is also fixedly installed on the outer end of one of the rotating rods 18. Rotating the knob 19 drives the worm 17 to rotate through the rotating rod 18. Under the rotational meshing action, the worm 17 drives the rotating tube 13. After the rotating tube 13 rotates through the bearing 9, it can be convenient to adjust the spray angle of the spray nozzle 2.

[0026] like Figure 2 and Figure 5 As shown, a second internal thread 14 is provided on the inner wall of the rotating tube 13, and a second external thread connector 5 that is threadedly connected to the second internal thread 14 is fixedly installed at the bottom end of the spray nozzle 2. The spray nozzle 2 can be installed on the rotating tube 13 by threading the second external thread connector 5 to the second internal thread 14, so that the spray nozzle 2 can be adjusted in angle through the rotating tube 13.

[0027] The specific operating principle of the adjustment mechanism 3 in conjunction with the greening irrigation sprinkler head 2 is as follows:

[0028] The adjusting mechanism 3 is pre-installed on the water supply pipe 1 by connecting the first internal thread 7 on the inner wall of the connecting pipe 6 to the first external thread connector 4 installed at the top of the water supply pipe 1, and by connecting the second external thread connector 5 installed at the bottom of the sprinkler head 2 to the second internal thread 14 on the inner wall of the rotating pipe 13 in the through hole 11 opened through the top surface of the outer casing 10, so that the sprinkler head 2 is installed at the top of the rotating pipe 13. When it is necessary to irrigate a certain area of ​​green vegetation, the knob 19 installed on the outer wall of the connecting pipe 6 on one side of the outer casing 10 is manually turned. The knob 19 will drive the worm gear 1 The rotating rods 18 installed at both ends of the outer casing 10 rotate within the rotating holes 12 on the left and right side walls. The rotating rods 18 drive the worm gear 17 to rotate within the outer casing 10. At this time, because the worm wheel 15 is fixed to the rotating tube 13 through the sleeve hole 16 on the top surface, and the worm wheel 15 is meshed with the worm gear 17, the worm gear 17 will drive the worm wheel 15 to rotate under the rotational meshing action. Since the rotating tube 13 is fixedly installed with the outer ring of the bearing 9 fixed on the sleeve 8, the worm wheel 15 can drive the rotating tube 13 to pass through the bearing. 9. The sprinkler head 2 rotates synchronously, changing the position of the nozzles during rotation. The angle of the sprinkler head 2 can be adjusted 360 degrees horizontally until the nozzle position is adjusted to the designated position. Then, the water supply switch of the water supply pipe 1 is turned on, and tap water is delivered through the water supply pipe 1 to the connecting pipe 6. The water then passes through the sleeve 8 on the top surface of the connecting pipe 6 and enters the through hole 11. Finally, the tap water is sprayed onto the designated position by the adjusted sprinkler head 2 to irrigate the green vegetation. During the irrigation process, due to the worm gear 1... The self-locking feature between 5 and worm gear 17 ensures that the spray angle of the sprinkler head 2 will not change after being hit. Compared with traditional sprinkler heads 2, the angle of the sprinkler head 2 can be quickly adjusted and fixed according to the watering needs of green vegetation, and the situation of not being able to adjust the nozzle angle due to lack of tools is avoided. This improves the flexibility and accuracy of greening watering operations. The spray angle can be flexibly and accurately adjusted according to the shape of different green areas, the distribution of plant species, and the water requirements of different growth stages, so as to achieve efficient and water-saving precise water supply and effectively ensure the healthy growth of plants.
