Problems solved by technology

[0002] With the development of society, people pay more and more attention to greening construction and garden construction. However, in the process of daily garden plant care, the irrigation operation is relatively heavy. The existing sprinkler irrigation system mostly uses constant pressure water supply, and the sprinkler irrigation area is mostly circular or The fan-shaped surface is the main area, but for the square and rectangular sprinkler irrigation area, if you want to complete the sprinkler irrigation of all green plants, the water will inevitably be sprayed out of the sprinkler area. This process will cause a great waste of water resources, and for Such as triangular and other irregular figure sprinkler irrigation, the current sprinkler irrigation system is difficult to achieve efficiently
At present, most of the sprinkler irrigation devices on the market are simple mechanical sprinkler irrigation devices, which are not highly automated, and still cannot solve the problem of accurate coverage of irregular sprinkler irrigation areas

Embodiment 1

[0041] A garden sprinkler irrigation system and control method suitable for various special-shaped areas, such as Figure 1 to Figure 6As shown, it includes a water tank 1, a gear pump 2, an electro-hydraulic proportional pressure reducing valve 3, a stepper motor 8 and a nozzle 12. The gear pump 2 is placed in the water tank 1 so that the output end of the gear pump 2 is connected to the electro-hydraulic The input end of the proportional pressure reducing valve 3 is connected, the output end of the electro-hydraulic proportional pressure reducing valve 3 is fixedly connected with the nozzle pipe 12, and the nozzle sleeve 6 is arranged on the nozzle pipe 12, so that the nozzle sleeve 6 is sleeved on the nozzle pipe 12, the nozzle sleeve 6 is provided with a sleeve gear 9, and the output shaft of the stepping motor 8 is connected with a driving gear 7, and the sleeve gear 9 is meshed with the driving gear 7.

[0042] When in use, establish a coordinate system according to the ...

Embodiment 2

[0044] This embodiment is further optimized on the basis of the above embodiments, such as Figure 1 to Figure 6 As shown, further, the electro-hydraulic proportional decompression valve 3 is controlled by a computer or other controllers, so that the electro-hydraulic proportional decompression valve 3 controls the pressure of the liquid, so that the liquid ejected from the nozzle sleeve 6 from the above-mentioned geometry Spray irrigation from the center to the boundary position of the boundary curve, or from the boundary position of the boundary curve to the above-mentioned geometric center, so as to realize the spray irrigation of the plants between the above-mentioned geometric center and the boundary position of the boundary curve.

[0045] When the plant sprinkling between a group of geometric centers and the boundary position of the boundary curve is completed, the stepper motor 8 is controlled by a computer or other controller to make the nozzle sleeve 6 rotate at a cer...

Embodiment 3

[0047] This embodiment is further optimized on the basis of the above embodiments, such as Figure 1 to Figure 6 As shown, further, the electro-hydraulic proportional pressure reducing valve 3 and the stepping motor 8 are simultaneously controlled by a computer or other controllers, the electro-hydraulic proportional pressure reducing valve 3 controls the pressure of the liquid, and the stepping motor 8 controls the nozzle casing 6 The rotation angle is controlled so that the liquid ejected from the nozzle sleeve 6 rotates around the concentric curve whose geometric center is a boundary curve. Increase, and carry out the irrigation of the plants on the next group of concentric curves until reaching the boundary curve, so as to realize the precise irrigation of irregular irrigation areas.

Abstract

The invention discloses a landscape sprinkling irrigation system suitable for various special-shaped areas and a control method. The system comprises a water tank, a gear pump, an electro-hydraulic proportional pressure reducing valve, a stepping motor and a spraying pipe. The gear pump is arranged in the water tank, an output end of the gear pump is connected with an input end of the electro-hydraulic proportional pressure reducing valve, an output end of the electro-hydraulic proportional pressure reducing valve is fixedly connected with the spraying pipe, a nozzle sleeve sleeves the spraying pipe, and an included angle alpha is formed between the tail of the nozzle sleeve and the horizontal plane. A sleeve gear is arranged on the nozzle sleeve, a driving gear is connected with an output shaft of the stepping motor, and the sleeve gear is in mesh connection with the driving gear. The landscape sprinkling irrigation system and the control method have advantages that sprinkling irrigation of irregular sprinkling irrigation areas can be realized, and the sprinkling irrigation areas can be controlled accurately; by control of sprinkling irrigation water quantity of a certain point, sprinkling irrigation requirements of different plants in different landscape areas can be met; compared with a traditional sprinkling irrigation device, the landscape sprinkling irrigation system has the advantage of water saving.
