Detailed Implementation

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0023] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the die-cast parts of this invention are used. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] like Figure 1-5 As shown, this embodiment provides a water circuit structure for a hydraulically driven rotating ground-mounted watering device, including a base assembly 100 connected to a water-inlet ground-mounted device 16, a body 1 with a water storage chamber 2, a circumferential water outlet assembly 200, and a top water outlet assembly 300. The water inlet channel of the base assembly 100 connects to the water storage chamber 2. The body 1 has a water distribution plate 3 and a reversing component 4. The water distribution plate 3 divides the water storage chamber 2 into a lower chamber 21 and an upper chamber 22, and the reversing component 4 is located in the lower chamber 21. The water distribution plate 3 includes a central chamber 6 with a water wheel 5 and a first inclined water channel 7 and a second inclined water channel 8 connecting the central chamber 6. The upper chamber 22 is connected to the central chamber 6 through an upper opening 9. The body 1 has a central water guide column 11 and a water outlet 12 located on the top wall. The water outlet 12 cooperates with the circumferential water outlet assembly 200 to discharge water, and the central water guide column 11 cooperates with the top water outlet assembly 300 to discharge water.

[0025] This embodiment integrates circumferential and top water outlet functions onto a single hydraulically driven rotating platform, achieving comprehensive and efficient three-dimensional irrigation. Circumferential water outlet covers the surrounding horizontal area, while top water outlet supplements the central vertical irrigation. The two functions can work collaboratively or independently, allowing users to flexibly switch modes according to plant layout. This enables both uniform and widespread spraying and precise water supply to specific areas, significantly improving irrigation efficiency and water resource utilization. Simultaneously, the integrated design results in a compact structure and simple operation, meeting diverse horticultural needs while reducing operating costs and maintenance complexity, demonstrating a high degree of unity between functional integration and practicality.

[0026] Furthermore, such as Figure 1-5As shown, the base assembly 100 contains a gear assembly 13 that meshes with the water turbine 5. The gear assembly 13 meshes with the base assembly 100. When the water turbine 5 is driven by water from the first inclined waterway 7 or the second inclined waterway 8, the main body 1 rotates. The first inclined waterway 7 has a first inlet connecting to the lower cavity 21 below its end away from the central chamber 6, and the second inclined waterway 8 has a second inlet connecting to the lower cavity 21 below its end away from the central chamber 6. The base assembly 100 contains a first rotation limiting part 14 and a second rotation limiting part 15. A reversing member 4 extends into the base assembly 100. When the main body 1 rotates, the reversing member 4 changes position when it encounters the first rotation limiting part 14 or the second rotation limiting part 15 to close one of the first and second inlets, thereby achieving reversal of the main body 1 by switching the waterway driving the water turbine 5.

[0027] Water flows from the ground-mounted insert through the water inlet channel of the base assembly 100 into the lower chamber 21 of the water storage chamber 2 of the main body 1. The water flows through the lower chamber 21 and through the inlet, which is not currently closed by the reversing component 4, into the corresponding oblique waterway. Because the waterway is obliquely designed, the water flow impacts the blades of the waterwheel 5 in the central chamber 6 at a specific angle, driving the waterwheel 5 to rotate. The shaft of the waterwheel 5 drives the gear assembly 13, which meshes with it. The last gear of this gear set meshes with a component fixed to the base assembly 100. According to the principle of action and reaction, when the gear attempts to rotate, because the base assembly 100 is fixed to the ground by the ground-mounted insert, the reaction force will push the gear assembly 13 and the main body 1 to rotate around the base assembly 100. Thus, the hydraulic kinetic energy of the waterwheel 5 is converted into the mechanical energy of the circumferential rotation of the main body 1.

[0028] Initially, the reversing component 4 is not closed at the first inlet, and water flows in through the first inlet, driving the waterwheel 5 to rotate the main body 1 in a certain direction. As the main body 1 rotates, the reversing component 4, installed inside it, rotates synchronously. When the main body 1 rotates to a preset angle, the reversing component 4 contacts the first rotation limit part 14 located within the base assembly 100. Under mechanical interference, the reversing component 4 is pushed, causing a position switch that closes the first inlet while simultaneously opening the second inlet. The water path is switched. The water flow now enters the second inclined water path 8 from the second inlet. The inclination direction of the second inclined water path 8 is opposite to that of the first inclined water path 7, resulting in an opposite direction of impact on the blades of the waterwheel 5, thereby driving the waterwheel 5 to rotate in the opposite direction. The reverse rotation of the waterwheel 5, through gear transmission, drives the main body 1 to begin rotating in the opposite direction. When the main body 1 rotates in the opposite direction to another preset angle, the reversing component 4 contacts the second rotation limit part 15, is pushed back to its original position, re-closes the second inlet, opens the first inlet, the water flow switches again, and the main body 1 resumes its initial rotation. This cycle repeats, allowing the watering can automatically rotate and spray to cover a rectangular or fan-shaped area.

[0029] like Figure 1 , 4As shown, the base assembly 100 includes a base 17, a first limiting adjustment ring 18 and a second limiting adjustment ring 19 rotatable relative to the base. The first limiting adjustment ring 18 has a first rotation limiting portion 14, and the second limiting adjustment ring 19 has a second rotation limiting portion 15. The first limiting adjustment ring 18 and the second limiting adjustment ring 19 are used to adjust the relative positions of the first rotation limiting portion 14 and the second rotation limiting portion 15.

[0030] like Figure 2-5 As shown, preferably, the upper opening 9 is directly opposite the central water guide column 11, and the water distribution plate 3 is provided with an arc-shaped water guide beam 20 located above the upper opening 9. The water flowing from the central chamber 6 through the upper opening 9 into the upper cavity 22 and finally supplying the top water assembly 300 flows upward. The arc-shaped concave surface of the arc-shaped water guide beam 20 can converge and guide this upward water flow, allowing the water to flow in a concentrated manner towards the central water guide column 11, reducing turbulent impact and energy loss between the water flow and the inner wall of the upper cavity 22.

[0031] like Figure 1 , 2 As shown in Figure 4-11, preferably, the top-discharge water assembly 300 includes an adjusting sleeve 21 and an inner core 22 fitted inside the adjusting sleeve 21. The inner core 22 is sealed to the central water guide column 11. The lower end of the inner core 22 has a water inlet hole 23, the peripheral wall of the inner core 22 has a first water passage hole 24 and a second water passage hole 25, and the top of the inner core 22 has a spray nozzle 26. A water inlet channel is formed between the water inlet hole 23 and the first water passage hole 24, and a water outlet channel is formed between the second water passage hole 25 and the spray nozzle 26. A baffle wall 27 is provided in the inner core 22, which isolates the water inlet channel and the water outlet channel. A sealing plug is provided on the inner wall of the adjusting sleeve 21.

[0032] When the user rotates the adjusting sleeve 21, the sealing plug on its inner wall rotates accordingly. In the "open" position, the sealing plug avoids the first and second water passages on the inner core 22. Water enters from the lower end of the inner core 22, flows through the inlet channel, exits through the first water passage 24 to the interlayer between the adjusting sleeve 21 and the inner core 22, then enters the outlet channel through the second water passage 25, and finally exits from the top spray nozzle 26. In the "closed" position, rotating the adjusting sleeve 21 causes the sealing plug to precisely block the flow channel between the first water passage 24 and the second water passage 25, physically cutting off the path of water flow from the inlet channel to the outlet channel, thus achieving closure. This structure achieves reliable on / off switching through a single rotation action, and the operation is intuitive.

[0033] like Figure 9-11As shown, preferably, the inner core 22 is provided with a limiting head 28, and the adjusting sleeve 21 is provided with a limiting step 29. The limiting head 28 rests on the limiting step 29. The inner wall of the adjusting sleeve 21 also has a guide protrusion 30. The limiting head 28 is provided with an arc-shaped guide notch 31, and the guide protrusion 30 is inside the arc-shaped guide notch 31. The arc-shaped guide notch 31 is provided with a first limiting protrusion 32 and a second limiting protrusion 33. The guide protrusion 30 falls between any limiting protrusion and the wall of the arc-shaped guide notch 31 to fix the position of the adjusting sleeve 21 and the inner core 22 after rotational adjustment.

[0034] The engagement of the limiting head 28 and the limiting step 29 determines the axial relative position of the inner core 22 and the adjusting sleeve 21, preventing the adjusting sleeve 21 from being accidentally pulled out. The guide protrusion 30 is engaged within the arc-shaped guide notch 31, strictly limiting the rotation of the adjusting sleeve 21 within the notch's arc range. This structure also bears the main torque transmission, preventing the inner core 22 from rotating during adjustment and ensuring that only the position of the sealing plug changes. When the user rotates the adjusting sleeve 21, the guide protrusion 30 slides within the arc-shaped guide notch 31. When rotated to the preset "open" or "closed" position, the guide protrusion 30 engages in the groove formed by the first limiting protrusion 32 or the second limiting protrusion 33 and the notch wall. This produces a distinct "click" feel, clearly indicating to the user that the position is correct, and prevents the adjusting sleeve 21 from shifting due to water flow vibration or slight contact, ensuring stability.

[0035] like Figure 4-6 As shown, the circumferential water outlet assembly 200 includes a base 34, a nozzle 40, and a water distribution ring 35. The base 34 has multiple arc-shaped water channels 36, which are radially distributed so that their outlets face outwards circumferentially. Each arc-shaped water channel 36 has a nozzle at its outlet. Rotating the base 34 allows switching the inlet of different arc-shaped water channels 36 to the outlet 12, so that water jets are ejected from different nozzles. The water distribution ring 35 has a water distribution section extending towards the front of the nozzle, and the water distribution section includes multiple water distribution ridges 37 arranged circumferentially at intervals.

[0036] Rotating the water-dividing ring 35 adjusts the relative position of the water-dividing ridge 37 and the corresponding nozzle. When the water-dividing ridge 37 cuts into the original water jet from the nozzle, two physical effects occur. First, a segmentation effect: the water jet is forcibly divided into multiple thinner water jets by the edge of the water-dividing ridge 37. Second, a disturbance and obstruction effect: the water jet impacts the side of the water-dividing ridge 37, and some of the water is blocked, bounced, and diffused, changing its flow direction and kinetic energy. Rotating the water-dividing ring 35 changes the depth and position of the water-dividing ridge 37 cutting into the water jet, thereby continuously or progressively changing the total width and the number of clearly identifiable water jets in the final spray.

The above description of the embodiments is only for the purpose of helping to understand the present invention and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
