DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The implementation of the energy-saving irrigation device for water conservancy projects in the utility model is as follows: Figure 1-5 shown.

[0024] Example 1

[0025] The energy-saving irrigation device for water conservancy projects of this embodiment includes a main water pipe 1 for connecting to a water pump, a plurality of large water tank irrigation components and a plurality of small water tank irrigation components. The large water tank irrigation components and the small water tank irrigation components have the same structure. The large water tank irrigation components include a large water storage tank 2 and a plurality of first branch pipes 3 connected to the large water storage tank. A first pressure valve 4 is provided at the connection between the first branch pipe 3 and the large water storage tank 2 so that the water in the large water storage tank 2 flows to the first branch pipe 3 after the pressure reaches a certain level. The large water storage tank 2 is connected to the main water pipe 1 through a first connecting pipe; the small water tank irrigation components include a small water storage tank 5 and a plurality of first branch pipes 3 connected to the small water storage tank 5. A second branch pipe 7 is provided, and a second pressure valve 8 is provided at the connection between the second branch pipe 7 and the small water storage tank 5 so that the water in the small water storage tank 5 can flow to the second branch pipe 7 after the pressure is reached, and the small water storage tank 5 is connected to the main water pipe 1 through a second connecting pipe 9; a plurality of irrigation holes are provided on the first branch pipe and the second branch pipe (not shown in the figure); the water storage capacity of the large water storage tank 2 is greater than that of the small water storage tank 5, and the preset discharge pressure of the first pressure valve 4 is less than the preset discharge pressure of the second pressure valve 8, so that the irrigation water volume within the irrigation range covered by the large water tank irrigation component is greater than the irrigation water volume within the irrigation range covered by the small water tank irrigation component, thereby realizing precise energy-saving and water-saving irrigation.

[0026] The large water storage tank 2 includes an upper cylinder 10 and a lower conical funnel 11 structure. The first branch pipe 3 is connected to the lower part of the cylinder 10. The conical funnel 11 structure is provided with a plurality of supporting legs 12 to prevent the large water tank irrigation component from tilting. The structure of the small water storage tank is the same as that of the large water storage tank.

[0027] A screen 13 is provided inside the cylinder to place the water-soluble fertilizer required for irrigation, and fertilization and irrigation are carried out simultaneously to achieve energy saving; a cover 14 is provided on the upper part of the cylinder, and the cover 14 is threadedly connected to the cylinder. A handle 15 is provided on the cover 14 to assist the opening and closing of the cover 14. The opening and closing of the cover facilitates the water-soluble fertilizer to be placed in the cylinder.

[0028] The first pressure valve 4 includes a water baffle 16, a pull ring 17 arranged on the water baffle 16, and a spring 18. A pull ring 2 19 for connecting the spring 18 is arranged in the large water storage tank 2. One end of the spring 18 is connected to the pull ring 17 in the cylinder body, and the other end of the spring 18 is connected to the pull ring 2 19 arranged on the water baffle 16.

[0029] The inner cross-section of the pipe at the position where the first branch pipe 3 cooperates with the first pressure valve 4 is T-shaped. The aperture of the first branch pipe 3 is small at the position close to the large water storage tank 2, and the aperture at the position of the large water storage tank 2 is large. The water baffle 16 is blocked at the position with a small aperture of the first branch pipe 3, and water cannot flow through the water baffle 16. When the water pressure is too high, the water baffle 16 is flushed by water to the position with a large aperture of the first branch pipe 3, and water flows from the large water storage tank 2 to the first branch pipe 3; the structure of the second pressure valve 8 is the same as that of the first pressure valve 4, and the structure of the second branch pipe 7 is the same as that of the first branch pipe 3.

[0030] The first connecting pipe 6 is clamped with the main water pipe to facilitate connecting the large water storage tank 2 to the main water pipe 1; the second connecting pipe 9 is clamped with the main water pipe 1 to facilitate connecting the small water storage tank 5 to the main water pipe 1.

[0031] A first one-way valve 20 is provided on the first connecting pipe 6 to allow water to flow from the main water pipe 1 to the large water storage tank 2 in one direction, and a second one-way valve 21 is provided on the second connecting pipe 9 to allow water to flow from the main water pipe 1 to the small water storage tank 5 in one direction.

[0032] The energy-saving irrigation device for water conservancy projects of the utility model has a large amount of water in the main water pipe during operation, and water is transported to multiple large water tank irrigation components and multiple small water tank irrigation components. The large water storage tank and the small water storage tank store more water in a short time. At this time, the first pressure valve and the second pressure valve are both opened under the water pressure, and water continues to flow into the first branch pipe and the second branch pipe, and then irrigation is carried out through the irrigation holes. When the irrigation water volume reaches the requirement, the water inlet of the main water pipe is closed, and the first check valve and the second check valve on the first connecting pipe and the second connecting pipe are automatically closed. The water in the large water storage tank and the small water storage tank will not flow back to the main water pipe, but will continue to flow out through the first pressure valve and the second pressure valve. Because the first pressure valve and the second pressure valve are arranged at the lower part of the cylinder, the water will eventually almost all flow out of the cylinder.

[0033] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
