Description

Technical Field

[0001] This utility model relates to the field of nozzles, and more particularly to the field of rotary nozzles, specifically referring to a rotary nozzle. Background Technology

[0002] Sprinklers used for watering flowers and gardens mainly include rocker-arm type, buried type, refraction type, and miniature sprinkler head. Most of these sprinkler heads are made of metal, which is not only complex in structure, prone to clogging and damage, but also relatively expensive. Because these sprinkler heads spray water in one or two streams with a relatively long spray distance, while miniature sprinkler heads have the disadvantage of a shorter spray distance, they all have certain limitations in use.

[0003] Currently, rotary sprinklers are used, including internally rotating and externally rotating sprinklers, and are commonly used in agricultural irrigation, landscaping, and dust suppression in industrial and mining fields. Their core working component is a rotating disc, which typically has water distribution channels. During operation, water flow drives the disc to rotate, and the water is amplified and sprayed out through these channels. The sprinkler's range, uniformity, and efficiency largely depend on the structural design of the rotating disc's water distribution channels.

[0004] Currently, most rotary water distribution channels on the market are simple groove or channel structures. This traditional design results in wide channels, preventing the water flow from being effectively accelerated again within the distribution channel, thus limiting its range and energy efficiency: insufficient water outlet velocity directly leads to an unsatisfactory spray range. To meet coverage requirements, users are often forced to increase the system's operating pressure, which not only increases energy consumption but may also lead to excessive water atomization, causing water waste and uneven spraying, especially in windy environments.

[0005] Therefore, there is an urgent need in this field for a method to innovatively design the internal flow channel of the water distribution tank, which can actively guide and constrain the water flow without increasing the inlet water pressure, and accelerate the water flow by changing the cross-sectional area of ​​the flow channel, thereby fundamentally improving the range and efficiency of the nozzle. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a rotating nozzle that actively guides and constrains water flow without increasing inlet water pressure. It accelerates the water flow by changing the cross-sectional area of ​​the flow channel, thereby fundamentally improving the nozzle's range and efficiency.

[0007] This utility model is achieved through the following technical solution: a rotating nozzle, including a rotating disk rotatably connected to the frame and located directly above the water inlet, and several water guide grooves opened on the water-facing surface of the rotating disk, wherein water guide grooves are provided with water divider blocks to guide the water flow to split and spray.

[0008] When in use, the water flows along the guide channel. Upon encountering the water divider block, the water divider block separates the guide channel cavity into two parts, dispersing the water flow. With a constant water velocity, the channel narrows, and the water flow accelerates and sprays out, thus allowing the water to spray further. Without increasing the inlet water pressure, it actively guides and constrains the water flow, achieving water flow acceleration by changing the cross-sectional area of ​​the flow channel, thereby fundamentally improving the range and efficiency of the nozzle.

[0009] Preferably, the water divider is located at the outlet of the water guide channel, and its outer end face is flush with the outlet end face of the water guide channel. This preferred solution, by positioning the water divider, avoids the water flow from being too close to the inlet of the water guide channel, which would cause the flow to rejoin after diversion, thus failing to achieve the desired water splitting effect. By aligning the water divider with the outlet end face of the water guide channel, the water flow remains dispersed at the outlet, ensuring water splitting.

[0010] Preferably, the cross-section of the water divider is triangular, and the thickness of the water-facing side of the water divider is less than the thickness of the water-repellent side. In this preferred embodiment, the water flows from bottom to top, first contacting the water-facing side of the water divider and being separated by it, thus facilitating the guidance of the water flow from both sides of the water divider.

[0011] Preferably, the water-dividing troughs with the water-dividing blocks are arranged at intervals of one trough. This preferred solution achieves simultaneous spraying at both near and far distances by arranging the water-dividing blocks at intervals, thereby expanding the spraying area.

[0012] Preferably, the water divider is located in the middle of the water outlet of the water guide channel. This preferred solution, by setting the position of the water divider, makes the water flow evenly distributed, thereby making the water jet distance on both sides similar.

[0013] Preferably, the outlet of the water guide channel is flush with the arc segment corresponding to the position of the rotating disk. In use, when viewed from above, the rotating disk is circular, and the outlet of the water guide channel extends to the circumference of the rotating disk. Therefore, the arc-shaped design of the outlet of the water guide channel facilitates the processing of the water guide channel on the rotating disk.

[0014] Preferably, the top surface of the rotating disk has a groove, and the top surface of the water guide groove has several arc-shaped protrusions evenly arranged circumferentially at the bottom of the groove. This preferred solution reduces the weight of the rotating disk by providing the groove, facilitating its rotation under the impact of water flow.

[0015] The beneficial effects of this utility model are as follows: the water flows along the guide channel, and after encountering the water divider block, the water divider block separates the guide channel cavity into two parts. The water flow is dispersed by the water divider block. Under the condition of constant water velocity, the channel narrows and the water flow is accelerated and sprayed out, thereby making the water flow spray farther. Without increasing the inlet water pressure, it actively guides and constrains the water flow. The water flow is accelerated by changing the cross-sectional area of ​​the flow channel, thereby fundamentally improving the range and efficiency of the nozzle. By setting the position of the water divider block, it is avoided that the water divider block is close to the water inlet of the guide channel, so that the flow will rejoin after splitting, thus failing to achieve the effect of water splitting. By setting it flush with the water outlet end face of the guide channel, the water flow is kept in a dispersed state at the water outlet of the guide channel, thereby ensuring water splitting.

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] See attached document Figure 1-5 This utility model discloses a rotating nozzle, comprising a frame as described in the prior art. The frame includes a bottom pipe 1 threadedly connected to a water inlet pipe, and a frustum tube 11 fixed to the top surface of the bottom pipe 1. The frustum tube 11 and the bottom pipe 1 are arranged coaxially. The large-diameter end of the frustum tube 11 is fixed to the bottom pipe 1. Two oppositely arranged side ears are provided on the circumference of the frustum tube 11. A cylindrical tube 12 with an outer diameter smaller than the outer diameter of the small-diameter end of the frustum tube 11 is fixed to the top surface of the frustum tube 11. A spray pipe 24 with a diameter smaller than the cylinder is fixed to the top surface of the cylindrical tube 12. Four spring pieces 23 are fixedly attached to the top surface of the cylindrical tube 12, which are evenly arranged circumferentially. In the top view, the inner surfaces of the four spring pieces 23 are all located on the first circle. The first circle is coaxial with the water spray pipe 24, and the radius of the first circle is larger than the radius of the water spray pipe 24. An inclined block 25 is fixedly attached to the outer surface of the spring piece 23, which is inclined from the inside to the outside. The outer surface of the inclined block 25 is an arc surface. The outer surfaces of the inclined blocks 25 are all located on the outer circumferential surface of the same frustum. This frustum is coaxial with the water spray pipe 24.

[0019] A circular disc is fitted on the cylindrical tube 12 between the inclined block 25 and the frustum tube 11. The inner diameter of the circular disc is greater than the outer diameter of the cylindrical tube 12 and less than the diameter of the small diameter end of the frustum tube 11. The inner diameter of the circular disc is less than the maximum outer diameter of the frustum where the inclined block 25 is located, and the inner diameter of the circular disc is greater than the minimum outer diameter of the frustum where the inclined block 25 is located.

[0020] When the annular disk is fitted onto the cylindrical tube 12, it is placed on the outer circumference of several inclined blocks 25. Then, the annular disk is pushed downward. At this time, the annular disk causes the inclined blocks 25 and the spring piece 23 to be subjected to inward pressure. The spring piece 23 tilts inward, causing the inclined blocks 25 to move inward. At this time, the inner diameter of the annular disk is greater than the maximum outer diameter of the frustum where the inclined blocks 25 are located. Therefore, the annular disk enters the cylindrical tube 12. Afterward, the spring piece 23 restores its deformation, thereby limiting the annular disk. Since the inner diameter of the annular disk is greater than the outer diameter of the cylindrical tube 12, and the height of the annular disk is less than the height of the cylindrical disk, the annular disk can rotate on the cylindrical tube 12.

[0021] Three inserts 20 are fixedly attached to the top surface of the annular disk, evenly arranged in the circumferential direction. Small inserts 22 are inserted into the inserts 20. The outer circumferential surface of the small inserts 22 is matched with the inner circumferential surface of the inserts 20. The outer circumferential surface of the small inserts 22 is connected to the inner circumferential surface of the inserts 20 by friction. A large insert 21 is fixedly attached to the top surface of the small inserts 22. The outer diameter of the large insert 21 is matched with the outer diameter of the inserts 20. The top end of the large insert 21 is fixedly attached to the rotating disk 3.

[0022] The rotating disk 3 is an inverted cone shape. The rotating disk 3 is coaxial with the water spray pipe 24 and is located at the top of the water spray pipe 24. Several water guide grooves 32 are provided on the water-facing surface of the rotating disk 3. The water guide grooves 32 are arc-shaped grooves with a certain inclination angle, so that when the water flow impacts the rotating disk 3 from bottom to top, the rotating disk 3 rotates under the guidance of the water guide grooves 32, and the water flow sprays water in the circumference along the water guide grooves 32.

[0023] The bottom of the rotating disk 3 is provided with a water distribution channel that is connected to several water guide channels 32. The water distribution channel is provided with a downward extending cone block. The cone block is coaxially arranged with the water spray pipe 24, and the bottom of the cone block is the small diameter end.

[0024] In this scheme, the water guide channel 32 is provided with a water divider block 30 to guide the water flow to split and spray. The water divider block 30 is located at the water outlet of the water guide channel 32. The outer end face of the water divider block 30 is flush with the water outlet end face of the water guide channel 32, and the water divider block 30 is located in the middle of the water outlet of the water guide channel.

[0025] The cross-section of the water-dividing block 30 is triangular, and the thickness of the water-facing side of the water-dividing block 30 is less than the thickness of the water-repellent side. Water-dividing channels of the water-dividing block 30 are arranged at intervals. The outlet of the water-guiding channel is flush with the arc segment corresponding to the position of the rotating disk 3. In a top view, the rotating disk 3 is circular, and the outlet of the water-guiding channel 32 extends to the circumference of the rotating disk 3. Therefore, the outlet of the water-guiding channel 32 is designed as an arc surface, which facilitates the machining of the water-guiding channel 32 on the rotating disk 3.

[0026] The top surface of the rotating disk 3 is provided with a groove, and the top surface of the water guide groove 32 forms several arc-shaped protrusions evenly arranged in the circumferential direction at the bottom of the groove.

[0027] In use, the water flows along the guide channel 32. Upon encountering the dividing block 30, the dividing block 30 divides the cavity of the guide channel 32 into two parts, dispersing the water flow. With a constant water velocity, the channel narrows, and the water flow accelerates, allowing the water to spray further. Without increasing the inlet pressure, it actively guides and constrains the water flow, accelerating it by changing the cross-sectional area of ​​the flow channel, thereby fundamentally improving the nozzle's range and efficiency. The positioning of the dividing block 30 prevents it from being too close to the inlet of the guide channel 32, causing the water to merge again after splitting, thus failing to achieve the effect of water splitting. By being flush with the outlet end face of the guide channel 32, the water flow remains dispersed at the outlet of the guide channel 32, ensuring water splitting.
