Lawn watering device with function of self-adjusting water spraying direction based on sunlight illumination area

Abstract

The invention discloses a lawn watering device with the function of self-adjusting the water spraying direction based on a sunlight illumination area, and relates to the technical field of energy saving and environmental protection. The lawn watering device with the function of self-adjusting the water spraying direction based on the sunlight illumination area comprises a water tank, one end of a water guide pipe is inserted in the bottom of the water tank, the water guide pipe is communicated with an inner cavity of the water tank, a cylinder is welded to the top of the water tank, six water spraying pipes are equidistantly inserted in the top of the cylinder in a surrounding shape, six extension rods are equidistantly inserted in the side surface of the cylinder in a surrounding shape, and three adjusting mechanisms equidistantly sleeve each extension rod in a row. According to the lawn watering device with the function of self-adjusting the water spraying direction based on the sunlight illumination area, thermal energy generated by direct sunlight on a glass cover is adopted as power of the adjusting mechanisms, based on the power source, the adjusting mechanisms are located in the sunlight illumination area, so that normal sprinkling irrigation of the water spraying pipes is not intervened in, and when the adjusting mechanisms are located in a tree shade area, inner cavities of bent water pipes are gradually sealed.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a lawn watering device which can self-adjust the water spraying direction based on the sunlight irradiation area. Background technique [0002] Sprinkler irrigation technology is to spray the water body into the air under a certain pressure through the pressurization method of the water pump and the pipeline or use the drop of the natural water source to form a water mist with a large coverage area and achieve the irrigation effect after the water mist falls in contact with the lawn. The unique irrigation method is convenient to use while achieving the effect of water saving, and can achieve the effect of covering the dust particles in the air to a certain extent, thereby further improving its environmental protection effect. However, in the actual sprinkling process, the position of the sun keeps moving, which leads to the continuous change of ...

Problems solved by technology

However, in the actual sprinkling process, the position of the sun keeps moving, which leads to the continuous change of the lawn’s illumination angle. When it is blocked by big trees and bushes, some lawns are in a non-illuminated state. Part of the lawn has a slow water evaporation rate, while other parts of the lawn have a faster water evaporation rate due to the greater light intensity. Based on the characteristics of different light intensities in different parts of the gardening lawn with trees and shrubs, the ordinary sprinkler irrigation method It cannot meet the normal water demand of the lawn. Long-term uneven sunlight leads to different water demand in different areas of the lawn. However, the sprinkler irrigation method with the same watering amount in each part can easily cause obvious color differences in different areas of the lawn, and even some lawns will die. , which greatly affects the ornamental quality of the lawn and the normal growth of plants
