[0003] With the continuous development of solar sprinkler irrigation, existing technical solutions have been widely used. However, these products still face some problems in practical use. For example, existing solar sprinkler systems often suffer from low automation, limited irrigation range, and slow response to soil moisture. This leads to low irrigation efficiency, water waste, and inaccurate control of the crop growth environment.

[0004] Specifically, a search revealed an environmentally friendly greening irrigation and maintenance device with publication number CN214853292U, published on November 26, 2021. This design utilizes a water pump powered by a solar receiver and a sprinkler system controlled by a soil moisture sensor. While capable of achieving basic automated sprinkler irrigation, the fixed sprinkler system has a limited irrigation range and requires improved response speed and accuracy to soil moisture changes. Consequently, irrigation effectiveness and water resource utilization efficiency in complex environments remain to be improved. Therefore, this design cannot meet the demand for highly automated and responsive sprinkler irrigation.

[0005] A search revealed a device for automatically controlling sprinkler irrigation based on soil moisture, with publication number CN210726261U, published on June 12, 2020. This device utilizes a humidity sensor and a rotating sprinkler head. While capable of certain automated control, the device's limited coverage and lack of flexibility and adaptability for irrigating large areas and multiple crop types make it difficult to achieve precise irrigation. Consequently, this design struggles to meet the demand for new sprinkler systems requiring intelligence, high adaptability, and wide-scale irrigation.

[0006] The above issues indicate that existing solar-powered sprinkler systems on the market struggle to effectively address the high-precision, high-efficiency, and highly adaptable irrigation needs in complex environments. Therefore, this utility model provides an adaptive, daily rotating solar-powered sprinkler system to overcome these shortcomings and offer a new, more intelligent, efficient, and adaptable solution for changing environments.

The base also houses a power management module, including a battery pack and a charge controller. The battery pack is used to store the electricity generated by the solar panel assembly, and the charge controller is used to manage the battery pack's charging and discharging processes.

[0013] The working principle and beneficial effects of the utility model are as follows:

Simultaneously, the rotating mechanism drives the sprinkler head assembly to rotate 360 ​​degrees, expanding the irrigation range and achieving full coverage.

[0015] Through the multi-point deployment of soil moisture sensors and the use of wireless communication modules, soil moisture changes within the irrigation area are monitored in real time and the data is transmitted to the control system.
