TECHNICAL FIELD

[0001] The utility model belongs to the field of sunlight tracking and energy saving, specifically to an energy-saving type automatic follow the sunlight direction sprinkling irrigation machine. BACKGROUND

[0002] With the continuous development of sunlight tracking and energy saving field, the existing sunlight tracking products have been widely applied. However, these products still have some problems in actual use. For example, the existing sunlight tracking and energy saving usually have the problems of complex operation, high maintenance cost and low energy utilization efficiency, which leads to low efficiency and unstable performance in actual application.

[0003] In order to solve these problems, there have been some attempts, such as using automatic control system and optimization design to improve energy utilization efficiency. Although these methods improve the relevant aspects to some extent, they still have limitations, such as the automatic control system may be too complex, leading to increased maintenance cost; the optimization design may not work well in some specific environments.

[0004] Specifically, after searching, a sunlight tracking speed reducer (CN206788660U) was disclosed, with a publication date of 2017-12-22. The design adopts the combination of motor, speed reducer, rotary support and solar cell connecting piece, which can realize the basic function of sunlight tracking, but due to its complex structure, it is prone to high maintenance cost and high failure rate in long-term use. Therefore, this design cannot meet the requirements of low maintenance cost and high reliability in energy-saving type automatic follow the sunlight direction sprinkling irrigation machine.

[0005] After searching, a natural environment sunlight double-axis tracking energy gathering exposure aging test device (CN212179265U) was disclosed, with a publication date of 2020-12-18. The product adopts the combination of sunlight double-axis tracking mechanism, linear condensing mirror mechanism, sample test table, microcomputer spraying mechanism and cooling unit, which has certain automation capability, but since its design is mainly aimed at aging test rather than actual application of sprinkling irrigation demand, it cannot adapt to the high requirements of sunlight tracking precision and energy utilization efficiency of sprinkling irrigation system in actual application. Therefore, this design is difficult to meet the demand of intelligent and efficient energy utilization of new sprinkling irrigation machine.

Therefore, the utility model provides an energy-saving type automatic follow the sunlight direction sprinkling irrigation machine to overcome these shortcomings and provide a new solution that is more intelligent, efficient and adaptable to changing environment.
