Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sprinkler irrigation device for water conservancy projects. Background Art

[0002] In agriculture, landscape gardening and urban greening, an effective irrigation system is essential to ensure plant growth and save water resources. Traditional irrigation methods such as ground flooding or manual watering are often inefficient and consume a lot of water resources. Therefore, the development of an efficient and water-saving sprinkler irrigation device has become an important demand in the field of water conservancy engineering.

[0003] The patent with announcement number CN211185261U discloses a sprinkler device for water conservancy projects. When performing agricultural water conservancy sprinkler irrigation, the waterwheel body is used to facilitate the movement of sprinkler irrigation to different places, and it saves costs. Water is drawn from the water source through a pumping pipe for sprinkler irrigation. At the same time, the coordinated design of the driving motor, turntable, rotating rod, arc-shaped fixed block, and rotating pipeline is used to periodically adjust the position of the sprinkler head, so that the sprinkler head can sprinkle irrigation on crops in all directions, which is beneficial to the absorption and utilization of crops.

[0004] However, the patent still has the following defects: on the one hand, the sprinkler head rotates periodically, and the residence time during the rotation is relatively short, resulting in less water in the sprinkler area during the rotation; on the other hand, the angle of the sprinkler head to the horizontal direction cannot be adjusted, so that the device can only irrigate within a specific range, and the sprinkler area is relatively concentrated. The above situation causes the sprinkler area of the device to be concentrated at three concentrated points during the sprinkler irrigation process, with a small range and poor uniformity.

[0005] In view of this, how to change the current situation that the irrigation range of existing sprinkler irrigation devices is relatively concentrated, resulting in poor irrigation uniformity, has become a technical problem that technical personnel in this field urgently need to solve.
