Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology, specifically relating to a water-saving nozzle structure. Background Technology

[0002] A sprinkler system is a piping system or device used to spray water or liquids. This system can be used for a variety of purposes, including irrigation, firefighting, landscaping, fountains, and other applications requiring liquid spraying. Traditional sprinklers typically have some limitations: Firstly, they use fixed nozzles or a single rotating structure, resulting in a fixed spray direction. This makes it impossible to dynamically adjust the spray angle based on crop distribution or terrain, failing to meet the diverse needs of different spray directions in various scenarios. For example, when irrigating plants of different heights or layouts, it's difficult to accurately spray water to the target location, leading to water waste. Secondly, the connection methods between sprinklers are inconvenient, generally rigid connections, making it difficult to flexibly adjust the sprinkler layout according to actual needs. Furthermore, leaks are prone to occur at the connection points, further reducing the efficiency of sprinkler irrigation and water resource utilization. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a water-saving spray pipe structure. By rotating the outer pipe, the spray direction can be adjusted, and a ring-shaped airbag seal can be used to block non-target nozzles. With the help of a metal hose, the spray pipe can be flexibly connected, improving irrigation accuracy and water-saving effect.

[0004] The solution adopted by this utility model to solve its technical problem is: a water-saving spray pipe structure, including a spray pipe, an outer pipe, an annular airbag seal, and a metal hose. The end of the spray pipe is provided with a pipe joint, and adjacent spray pipes are connected by a metal hose. Multiple nozzles are arranged in a straight line along the pipe body, and different types of nozzles are distributed circumferentially along the spray pipe. An outer pipe is rotatably fitted outside the spray pipe. A water spray nozzle is opened on the outer pipe. By rotating the outer pipe, the water spray nozzle is aligned with the nozzles in different directions, thereby adjusting the water spray direction. The annular airbag seal is disposed between the outer pipe and the spray pipe. One side of the annular airbag seal is fixed to the inner wall of the spray pipe, and the other side faces the nozzle of the spray pipe. The annular airbag seal avoids the water spray nozzle. A suction component for filling and extracting gas into the annular airbag seal is provided outside the outer pipe.

[0005] Furthermore, the suction assembly includes an air cylinder and a rigid air tube. The air cylinder is connected to an annular airbag seal inside the outer tube via the air tube. A piston is fitted inside the air cylinder, and a pressure regulating chamber is located below the piston. A screw hole is opened at the center of the upper end of the air cylinder, and an adjusting bolt is threaded into the screw hole. The lower end of the adjusting bolt is mounted on the piston.

[0006] Furthermore, quick-connect fittings are installed at both ends of the metal hose, and the quick-connect fittings are sealed and installed on the pipe joints at the ends of the nozzle.

[0007] Furthermore, the outer tube is provided with ring baffles at both ends, and the nozzle is fixed with fixed ring seats at both ends. The ring baffles are located inside the fixed ring seats. The fixed ring seats and the ring baffles are respectively provided with multiple bolt holes. Positioning bolts are installed in the bolt holes. The nozzle and the outer tube are positioned by means of the bolt holes and positioning bolts.

[0008] Furthermore, a support is provided below the nozzle, including a triangular bracket longitudinally fixed on a fixing ring seat at the end of the nozzle, and an anchor rod is provided at the lower end of the triangular bracket.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] Flexible and adjustable water spray direction: This water-saving nozzle structure integrates nozzles of different types and spray directions on the nozzle and sets up a rotatable outer tube. By simply rotating the outer tube to make the nozzles correspond to the nozzles in different directions, the water spray direction can be easily adjusted, realizing multi-directional and multi-angle water spray adjustment, meeting the diverse needs for water spray direction in different scenarios, and improving the versatility and practicality of the nozzle.

[0011] Effective water conservation: Gas is injected into the annular airbag seal using the suction component, causing the annular airbag seal to bulge and seal against the other nozzles of the nozzle pipe. This ensures that only the nozzle corresponding to the water spray nozzle is connected, while the other nozzles are blocked, thereby preventing water leakage from non-target nozzles, improving the accuracy of water spraying, reducing water waste, and achieving the effect of water conservation.

[0012] Easy and stable connection: Adjacent nozzles are connected by a flexible metal hose. Quick-connect fittings installed at both ends of the flexible metal hose can be sealed on the pipe joints at the ends of the nozzles, facilitating quick connection and disassembly between nozzles. At the same time, it ensures the sealing of the connection and prevents water leakage. The flexible metal hose is also flexible, allowing adjacent nozzles to be placed in any position. This ensures that multiple nozzles can be accurately aimed at the plants, adapting to various complex terrains and plant layouts. This further improves the accuracy of watering and enhances the flexibility and adaptability of nozzle arrangement.

[0013] Stable and reliable support: The support components installed below the nozzle, including the triangular bracket longitudinally fixed to the fixing ring seat at the end of the nozzle and the anchor rod at its lower end, can stably support the nozzle in the farmland. The anchor rod is inserted into the soil, which effectively improves the support stability of the nozzle and ensures that the nozzle is not easy to tip over or move during use, thus ensuring the smooth progress of sprinkler irrigation operations.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-5 This utility model provides a technical solution for a water-saving nozzle structure: Example

[0022] According to the diagram Figure 2 As shown, a water-saving spray pipe structure mainly includes a spray pipe 1, an outer pipe 2, and an annular airbag sealing body 3. The end of the spray pipe 1 is provided with a pipe connector 8, which connects the spray pipe 1 to an external water source. Multiple nozzles are arranged in a straight line along the extension direction of the pipe body on the spray pipe 1, and different types of nozzles are distributed circumferentially on the spray pipe 1. For example, the nozzles facing downward on the spray pipe 1 are spray nozzles that spray water directly downwards, which can evenly spray a fine mist like rain, forming a stable mist like rain. The sprayed water column or mist will cover the area directly below the nozzle, which is suitable for lower plants. The nozzles facing upward on the spray pipe 1 are multi-hole nozzles that spray water upwards, forming an upward hemispherical or umbrella-shaped mist area, which is suitable for taller plants. The nozzles facing left and right on the spray pipe 1 will spray water to the left or right. Depending on the spray angle and pressure of the spray pipe 1, horizontal spraying over a long distance can be achieved, covering an area of ​​a certain width and length in front. By integrating different nozzles or nozzles with different orientations onto a single nozzle 1, users can achieve multi-directional and multi-angle water spray adjustment using only one nozzle 1.

[0023] like Figure 3 and Figure 4 As shown, an outer tube 2 is fitted around the outside of the nozzle 1. The outer tube 2 is movably fitted around the outside of the nozzle 1. A water nozzle 4 is provided on the outer tube 2. The water nozzle 4 matches the nozzle head. The water flow from the nozzle head can be sprayed outward through the water nozzle 4. Ring baffles 5 are provided at both ends of the outer tube 2. Fixed ring seats 6 are fixed at both ends of the nozzle 1. The ring baffles 5 are located inside the fixed ring seats 6, and the two rotate around each other. The fixed ring seats 6 restrict the outer tube 2 to the nozzle 1 through the ring baffles 5, so that the outer tube 2 can only rotate around the outside of the nozzle 1 along the axis and cannot move left or right. By rotating the outer tube 2, the water nozzle 4 can be aligned with the nozzles in different directions on the nozzle 1, thereby adjusting the water spray direction of the nozzle 1.

[0024] like Figure 3 and Figure 5 As shown, in order to achieve smooth water spraying from the nozzle 4 and block other nozzles, a sealing element is provided between the outer pipe 2 and the spray pipe 1. The sealing element is an annular airbag seal 3. One side of the annular airbag seal 3 is fixed to the inner wall of the spray pipe 1, and the other side faces the nozzle of the spray pipe 1. The sealing element avoids the nozzle 4 so that the nozzle 4 can spray water smoothly. An air cylinder 11 is provided outside the outer pipe 2. The air cylinder 11 is connected to the annular airbag seal 3 inside the outer pipe 2 through a rigid air pipe 12. A piston 13 is fitted inside the air cylinder 11. The lower part of the piston 13 is a pressure regulating chamber. A screw hole is opened at the center of the upper end of the air cylinder 11. An adjusting bolt 14 is threaded in the screw hole. The lower end of the adjusting bolt 14 is installed on the piston 13. The piston 13 can be moved up and down by adjusting bolt 14. When piston 13 moves down, it squeezes the gas in the pressure regulating chamber into the annular airbag seal 3, causing the annular airbag seal 3 to bulge and seal against the other nozzles of the nozzle pipe 1, sealing the remaining unused nozzles. The annular airbag seal 3 is a flexible structure that can adapt to the shape of the nozzle to provide an effective seal and also provides a pressure clamping effect. At this time, only the nozzle corresponding to the water nozzle 4 is connected, and the other nozzles are blocked, thus realizing water spraying from the nozzle corresponding to water nozzle 4. When it is necessary to change the water spraying direction or mode of the nozzle pipe 1, the piston 13 is moved up by adjusting bolt 14. The volume of the pressure regulating chamber increases and the gas inside the annular airbag seal 3 is drawn out. The annular airbag seal 3 collapses and releases the sealing and clamping effect on the other nozzles. Then the outer tube 2 can be rotated to change the orientation of the water nozzle 4, so that the water nozzle 4 is aligned with the nozzles in other directions, thus easily realizing the adjustment of the water spraying mode of the nozzle pipe 1.

[0025] To further improve the positioning effect of the outer pipe 2 and the water nozzle 4 when the nozzle 1 sprays water, multiple bolt holes 7 are correspondingly opened through the fixing ring seat 6 of the nozzle 1 and the ring baffle 5 of the outer pipe 2. The number of bolt holes 7 is consistent with the number of nozzles in different directions and their positions correspond. When adjusting the direction of the water nozzle 4 of the outer pipe 2, it can be determined whether the water nozzle 4 is adjusted in place by judging whether the bolt holes 7 are completely aligned. Then, positioning bolts are installed in the bolt holes 7. The positioning bolts can further improve the stability between the nozzle 1 and the outer pipe 2 and ensure the stability of water spraying.

[0026] In practical use, this utility model provides a water-saving spray pipe structure. The spray pipe 1 is connected to an external water source and water pump. The spray pipe 1 is used to spray water to irrigate plants or crops. During irrigation, the optimal spray direction is selected according to the growth height and position of the plant. By rotating the outer pipe 2, the spray nozzle 4 is rotated to the nozzle with the optimal spray direction. Then, the outer pipe 2 and the spray pipe 1 are locked by the positioning bolt. Next, the adjusting bolt 14 is turned to control the piston 13 to move downward, which pressurizes the gas in the pressure regulating chamber into the annular airbag sealing body 3. After the annular airbag sealing body 3 bulges, it seals the remaining nozzles of the spray pipe 1, sealing the remaining idle nozzles. Then, water flows through the spray pipe 1, and the water is sprayed out from the nozzle corresponding to the spray nozzle 4 to irrigate the plants. Example

[0027] Based on Example 1, since the plant growth area is not fixed when spraying water to irrigate crops or vegetation, in order to allow the spray nozzle to make adaptive adjustments according to the distribution of plants, so that the spray nozzle 1 can be accurately aimed at the plants, such as... Figure 1 As shown, multiple spray pipes 1 can be installed. The middle spray pipe 1 has pipe connectors 8 at both ends. The near end of the spray pipe 1 close to the water source is connected to the water source through the pipe connector 8, and the far end of the spray pipe 1 away from the water source is sealed. Adjacent spray pipes 1 are connected by a metal hose 9. Quick-connect fittings 10 are installed at both ends of the metal hose 9. The quick-connect fittings 10 can be sealed and installed at the ends of the spray pipe 1. The metal hose 9 and the quick-connect fittings 10 can seal and connect two adjacent spray pipes 1 together. This structure is similar to the connection method of a shower head and a shower head pipe. Furthermore, due to the flexibility of the metal hose 9, the adjacent spray pipes 1 can be adjusted and placed in any position to ensure that multiple spray pipes 1 can be accurately aimed at the plants, improve the accuracy of watering, reduce water waste, and thus achieve the effect of water conservation. Example

[0028] Based on Embodiment 1 and Embodiment 2, such as Figure 1 or Figure 2As shown, a support is provided below the nozzle 1, including a triangular bracket 15 longitudinally fixed on the fixing ring seat 6 at the end of the nozzle 1. An anchor rod 16 is provided at the lower end of the triangular bracket 15. When the nozzle 1 is laid out, the nozzle 1 can be supported in the farmland by the triangular bracket 15, and the anchor rod 16 inserted into the soil can further improve the support stability of the nozzle 1.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
