Description

Technical Field

[0001] The utility model relates to the technical field of irrigation in water conservancy projects, and particularly relates to an irrigation system for water conservancy projects. Background Art

[0002] A water conservancy project is a newly built project used to control and allocate surface water existing in nature to meet the needs of production and life. Water conservancy projects include rivers, storage lakes, reservoirs, spillways, sluice gates, water inlets, channels, aqueducts, raft channels, fishways, etc., which are used to allocate and control water flow to meet the needs of production and life and play the roles of flood control and drought resistance. Among them, irrigation is a technical measure to supplement the water required by crops. In order to ensure the normal growth of crops and obtain high and stable yields, sufficient water must be supplied to the crops. Under natural conditions, due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, irrigation must be carried out artificially to make up for the deficiency of natural rainfall. Irrigation means watering the land with water. The irrigation principle is that the irrigation amount, irrigation frequency and time should be determined according to the water requirements of medicinal plants, growth stages, climate and soil conditions, and it should be timely, appropriate and reasonable. Its types mainly include pre-sowing irrigation, seedling-promoting irrigation, growth-stage irrigation and winter irrigation, etc.

[0003] In the irrigation system of water conservancy projects, as a key component, the nozzle is often troubled by being blocked by impurities such as dust. The accumulation of dust will seriously affect the normal water spraying effect of the nozzle, not only causing waste of water resources, but also reducing the irrigation efficiency, and even may lead to insufficient local irrigation, affecting the growth of crops and bringing many inconveniences to agricultural production. Therefore, this application proposes an irrigation system for water conservancy projects. Summary of the Utility Model

[0004] The purpose of the utility model is to propose an irrigation system for water conservancy projects in view of the problem in the background art that the nozzle is easily blocked by impurities such as dust, affecting the normal water spraying effect of the nozzle and reducing the irrigation efficiency.

[0005] The technical solution of the utility model: An irrigation system for water conservancy projects includes a water tank. A water pump is fixedly installed on one side of the water tank. The water outlet of the water pump is fixedly connected to a main pipe. A plurality of branch pipes are detachably connected to the main pipe. Nozzles are fixed on the tops of the branch pipes. The nozzles are arranged in a cylindrical structure. A plurality of spray holes are formed in a circumferential and uniformly distributed manner on the curved surface of the nozzle.

[0023] Embodiment

[0024] As Figure 1 shown, a water conservancy project irrigation system proposed by the present utility model includes a water tank 1. A water pump 2 is fixedly installed on one side of the water tank 1. A valve 12 is installed on the conveying pipeline of the water pump 2, which is used to start and stop the conveying process of the water pump and control the flow rate of the water flow. The water outlet of the water pump 2 is fixedly connected to a main pipe 3. A plurality of branch pipes 5 are detachably connected to the main pipe 3. A pipe plug 4 is arranged at one end of the main pipe 3, which is used to block the port of the main pipe 3 to prevent water from flowing out of the port and causing insufficient water flow in the branch pipes. A threaded hole is opened at the top of the main pipe 3, and the outer wall of the branch pipe 5 is threadedly connected to the inner wall of the threaded hole, which is convenient for the disassembly and installation of the branch pipe 5.

[0025] As shown Figures 2 to 3 in the figure, a nozzle 6 is fixed at the top of the branch pipe 5. The nozzle 6 is arranged in a cylindrical structure. A plurality of spray holes 7 which are evenly distributed in a ring shape are formed in the curved surface of the nozzle 6. The inner diameter of the spray holes 7 is a variable-diameter hole, and the inner diameter of the spray holes 7 decreases from the inside to the outside of the nozzle 6. So that the sprayed water flow is gradually accelerated when passing through the spray holes 7, improving the initial velocity and impact force of the spray, thereby achieving a better effect in medium irrigation. A spray hole protection device is arranged on the nozzle 6. When not spraying water, it can effectively prevent dust, sundries, etc. from the outside from entering the spray holes 7 and causing blockage.

[0026] Furthermore, the spray hole protection device includes a disc 11 slidably installed in the nozzle 6. A slide rod 10 is fixedly installed at the top of the disc 11. The disc 11 slides to drive the slide rod 10 to slide. A protective sleeve 8 is slidably sleeved on the nozzle 6. The top end of the slide rod 10 slidably penetrates through the top of the nozzle 6 and is fixedly connected to the protective sleeve 8. The slide rod 10 slides to drive the protective sleeve 8 to slide. A sliding hole 9 is formed in the top of the nozzle 6. The slide rod 10 is slidably connected to the inner wall of the sliding hole 9. A spring which is slidably sleeved on the slide rod 10 is arranged between the inner wall of the top of the nozzle 6 and the disc 11. After the device is used, the protective sleeve 8 slides downward to reset due to the elastic support of the spring, thereby covering the spray holes 7 for protection.

[0027] Working principle: Open the valve 12 to convey water to the main pipe 3 through the water pump 2. The water flow is dispersed to each branch pipe 5 through the main pipe 3. When the water flow reaches the disc 11, the disc 11 is pushed upward due to the water pressure. The disc 11 slides to drive the slide rod 10 to slide. The slide rod 10 slides to drive the protective sleeve 8 to slide. When the disc 11 and the protective sleeve 8 are higher than the spray holes 7, the water flow will spray out from the spray holes 7. When the valve 12 is closed, the protective sleeve 8 slides downward to reset due to the elastic support of the spring, thereby covering the spray holes 7 for protection. It realizes that by simply opening and closing the valve 12, under the combined action of the water flow pressure and the elastic support of the spring, the protective sleeve 8 can be opened and closed. It not only ensures that the protective sleeve 8 can be quickly opened during irrigation, but also can be tightly closed when not needed, playing an effective protective role, greatly avoiding the blockage of the spray holes 7 by dust and other impurities when not in use, and improving the functionality and convenience of the device.

[0028] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
