A lawn watering device with self-adjusting water spraying direction based on the area irradiated by sunlight

Abstract

The invention discloses a lawn watering device which can self-adjust the water spraying direction based on the sunlight irradiation area, and relates to the technical field of energy saving and environmental protection. The lawn watering device, which self-adjusts the spraying direction based on the area irradiated by sunlight, includes a water tank, one end of the water guide pipe is plugged into the bottom of the water tank, and the water guide pipe communicates with the inner cavity of the water tank, and the top of the water tank is welded with a cylinder, and The top of the cylinder body is equidistantly surrounded by six water spray pipes, and the side surface of the cylinder is equidistantly surrounded by six extension rods. A single extension rod is equipped with three adjustment mechanisms in rows and equidistantly. The lawn watering device that self-adjusts the spraying direction based on the area irradiated by sunlight, the adjustment mechanism uses the heat energy that direct sunlight acts on the glass cover as power, and based on this power source, the adjustment mechanism is located in the area irradiated by sunlight so that the normal sprinkling of the water spray pipe is not performed. Intervention is performed so that the inner cavity of the bent water pipe is gradually closed when the adjustment mechanism is in the shade area.

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
