Description

Technical Field

[0001] This utility model relates to the field of water conservancy and irrigation technology, and in particular to a water-saving device for water conservancy and irrigation. Background Technology

[0002] Irrigation is a crucial element in ensuring agricultural yields. To avoid wasting water resources, sprinkler irrigation is currently widely used. This involves spraying irrigation water into the air, where it falls onto the crops under gravity.

[0003] In existing technologies, the nozzles rotate to increase the spray coverage, ultimately forming a circular spray area. The effective spray area is mainly the ring-shaped area near the largest edge, resulting in poor irrigation. Utility Model Content

[0004] The purpose of this utility model is to provide a water-saving irrigation device that can divert water flow through a partition plate, thereby improving the coverage and uniformity of irrigation and enhancing the irrigation effect.

[0005] This utility model provides a water-saving irrigation device, comprising:

[0006] An irrigation sprinkler head has an integrally formed partition plate inside the sprinkler head near its outlet. The partition plates are staggered to divide the internal space of the irrigation sprinkler head into independent water outlet channels. The two ends of the water outlet channels have different diameters. The smaller diameter end of the water outlet channel is closer to the outlet of the irrigation sprinkler head, and the difference in diameter between the two ends of the water outlet channel located at the upper end is greater.

[0007] Preferably, the cross-sectional diameter of the water outlet passage near the outlet is flat, and the lateral dimension of the water outlet passage near the outlet is smaller than its longitudinal dimension.

[0008] Preferably, the outlet end of the irrigation nozzle is angled upwards.

[0009] Preferably, the water-saving irrigation device further includes a water supply component, which includes a water supply pipe and an adapter. The water supply pipe is vertically arranged, the adapter is rotatably mounted on the upper end of the water supply pipe, and the irrigation nozzle is fixedly mounted on the adapter. The adapter connects the water supply pipe and the irrigation nozzle.

[0010] Preferably, the irrigation nozzles are evenly distributed around the adapter.

[0011] Preferably, a lever baffle is fixedly connected inside the adapter. The lever baffle is inclined to the direction of water flow. When the water flows vertically through the inside of the adapter, it impacts the lever baffle and causes the adapter to rotate.

[0012] Preferably, the leveraging baffle is inclined in the vertical direction, and a connecting column is integrally formed at the center of the adapter, with the leveraging baffle evenly distributed around the connecting column.

[0013] Preferably, the leverage baffles on the connecting column are distributed vertically in layers, with each layer of leverage baffles covering the entire circumference of the connecting column.

[0014] Preferably, the lever-assisted baffle is inclined in the horizontal direction and is fixedly connected to the inner wall of the adapter. When the water flows horizontally through the interior of the adapter, it drives the adapter to rotate by impacting the lever-assisted baffle.

[0015] Preferably, the water-saving irrigation device further includes a water supply pipe, a branch pipe connected to the irrigation nozzle is provided on the side wall of the water supply pipe, and a filter screen is provided at the connection between the water supply pipe and the branch pipe, the filter screen being flush with the inner surface of the water supply pipe.

[0016] The technical solution of this utility model forms a specific water outlet channel through the structural design of the partition plate. The different diameters at the two ends of the water outlet channel can accelerate the internal water flow and increase the irrigation area. The greater the difference in diameter between the two ends of the water outlet channel, the better the acceleration effect. By controlling the size of the difference in diameter between the two ends of the water outlet channel, the irrigation range can be controlled. Water outlet channels with different diameter differences are responsible for the irrigation tasks of different distance areas, improving the uniformity of irrigation and ultimately achieving better irrigation results.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Combination Figures 1 to 5As shown, the water-saving irrigation device provided by this utility model includes an irrigation nozzle 1.

[0029] Combination Figures 1 to 5 As shown, the irrigation nozzle 1 has an integrally formed partition plate 11 inside near its outlet end. The partition plates 11 are staggered to divide the internal space of the irrigation nozzle 1 into independent water outlet passages 10. The two ends of the water outlet passages 10 have different diameters. The smaller diameter end of the water outlet passage 10 is closer to the outlet of the irrigation nozzle 1, and the difference in diameter between the two ends of the water outlet passage 10 located at the upper end is greater.

[0030] In this embodiment, a structurally specific water outlet passage 10 is formed through the structural design of the partition plate 11. The different diameters at the two ends of the water outlet passage 10 can accelerate the internal water flow and increase the irrigation area. The greater the difference in diameter between the two ends of the water outlet passage 10, the better the acceleration effect. By controlling the size of the difference in diameter between the two ends of the water outlet passage 10, its irrigation range can be controlled. Water outlet passages 10 with different diameter differences are responsible for the irrigation tasks of different distance areas, improving the uniformity of irrigation. Placing the water outlet passage 10 with a larger diameter difference that is responsible for a farther location at the top can effectively avoid mutual interference between the water outlet passages 10, ultimately achieving a better irrigation effect.

[0031] In some embodiments, combined with Figure 1 , Figure 5 As shown, the cross-section of the water outlet passage 10 near the outlet is flat. The flat outlet can make the water flow more dispersed, thereby increasing the irrigation area covered by a single water outlet passage 10. The lateral dimension of the water outlet passage 10 near the outlet is smaller than its longitudinal dimension, that is, the flat outlet is set vertically.

[0032] In some embodiments, combined with Figures 1 to 3 As shown, the outlet of the irrigation nozzle 1 is set at an angle upward. The spraying distance of the irrigation nozzle 1 is the farthest when it is set at an angle of 45 degrees upward. However, the tilt angle of the irrigation nozzle 1 should be set according to actual needs to ensure the coverage effect.

[0033] In some embodiments, combined with Figure 1 As shown, the water-saving irrigation device further includes a water supply component 2, which includes a water supply pipe 21 and an adapter 22. The water supply pipe 21 is vertically arranged, and the adapter 22 is rotatably mounted on the upper end of the water supply pipe 21. The irrigation nozzle 1 is fixedly mounted on the adapter 22. The adapter 22 connects the water supply pipe 21 and the irrigation nozzle 1. By rotating the adapter 22, the irrigation nozzle 1 is moved to achieve a spraying effect covering a circular area.

[0034] The number of irrigation nozzles 1 on the adapter 22 can be multiple. For example, the irrigation nozzles 1 can be evenly distributed around the adapter 22 to reduce the irrigation time interval and thus increase irrigation efficiency.

[0035] In some embodiments, combined with Figures 2 to 4 As shown, in order to drive the adapter 22 to rotate, a lever baffle 23 is provided to borrow force from the water flow. The lever baffle 23 needs to be set at an angle to the direction of water flow. At the same time, it is ensured that the adapter 22 and the lever baffle 23 are fixedly connected to ensure the transmission of force. The flow of water in the adapter 22 can be divided into two parts: vertical flow into the adapter 22 and horizontal flow into the irrigation nozzle 1. Therefore, there are at least two ways to assemble the lever baffle 23.

[0036] The first type, combining Figures 2 to 3 As shown, the leveraging baffle 23 is inclined in the vertical direction. The connecting column is integrally formed at the center of the adapter 22. The leveraging baffle 23 is evenly distributed around the connecting column. When the water flows vertically through the interior of the adapter 22, it drives the adapter 22 to rotate by impacting the leveraging baffle 23. The overall shape of the leveraging baffle 23 needs to maintain rotational symmetry to ensure the stability of the leveraging process.

[0037] To increase the tilt angle of the leveraging baffle 23, the leveraging baffle 23 can be divided into multiple layers. That is, the leveraging baffle 23 on the connecting column is distributed vertically in layers, and each layer of the leveraging baffle 23 covers the entire circumference of the connecting column. At the same time, the distribution angle of the leveraging baffle 23 in each layer should be different to improve the overall leveraging effect.

[0038] The second type, combining Figure 4 As shown, the lever baffle 23 is inclined in the horizontal direction and is fixedly connected to the inner wall of the adapter 22. When the water flows horizontally through the interior of the adapter 22, it drives the adapter 22 to rotate by impacting the lever baffle 23.

[0039] In some embodiments, combined with Figure 5 As shown, the water-saving irrigation device also includes a water supply pipe 3. A branch pipe is provided on the side wall of the water supply pipe 3 to connect to the water supply pipe 21 to supply water to the irrigation nozzle 1. A filter screen 31 is provided at the connection between the water supply pipe 3 and the branch pipe. The filter screen 31 is flush with the inner surface of the water supply pipe 3. The filter screen 31 is there to prevent impurities from entering the irrigation nozzle 1 and causing blockage. Installing the filter screen 31 here can reduce the accumulation of impurities on the filter screen 31, because the water flow in the water supply pipe 3 will horizontally wash the surface of the filter screen 31.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
