Description

Technical Field

[0001] The utility model relates to the technical field of garden intelligent irrigation, in particular to an automatic sprinkler head regulating mechanism in an energy-saving garden intelligent irrigation system. Background Art

[0002] Garden irrigation is a technical measure to supplement the soil moisture required for the growth of garden plants in order to improve their growth conditions. It uses artificial or mechanical methods in different irrigation forms to supplement the soil moisture of garden green spaces and meet the water needs of plants. When spraying large areas of gardens, it is necessary to use atomizing spray devices.

[0003] After searching, a Chinese patent discloses a garden intelligent irrigation system (authorization announcement number CN214853326U), including a mounting plate, an electric telescopic rod is fixedly connected to the center of the upper surface of the mounting plate, and four angle adjustment mechanisms distributed in a circular array are arranged on the upper surface of the mounting plate. A diversion mechanism is arranged inside the mounting plate. The angle adjustment mechanism includes a rotating shaft, a telescopic sleeve, a telescopic round rod, a nozzle, a connecting plate and a plug rod. Although the patented technology can remotely control the telescopic sleeve in the angle adjustment mechanism to rotate around the rotating shaft as the axis through the electric telescopic rod, and then drive the nozzle on the telescopic sleeve to rotate around the rotating shaft as the axis, the spray angle of the nozzle can be adjusted, thereby achieving the purpose of adjusting the spray range of the nozzle. It is simple to operate and easy to use.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that in terms of irrigation of existing gardens, multiple sprinklers are installed in the garden vegetation to achieve large-area irrigation operations. However, this method cannot accurately identify water-deficient areas, and can only use large-area irrigation to cover the water shortage problem in a single area. Some garden vegetation areas are extremely short of water, while some garden vegetation areas have too much water. If irrigation continues, the roots may be unable to breathe, the leaves may dry out, and the vegetation may grow poorly. Utility Model Content
