Water-spraying device and method for public greening

Abstract

The invention relates to the field of sprinkling equipment, in particular to a water-spraying device for public greening.The water-spraying device for public greening is characterized in that a rotary spray head is hinged onto the top of a protection shield cover; a water-conveying pipe penetrates through a base to be communicated with the rotary spray head; a soil humidity sensor and a controller are arranged in the protection shield cover; a probe of the soil humidity sensor penetrates through the base to be inserted into greening land; a temperature sensor is arranged on the outer wall of a support ring; a flow regulating valve is arranged on the water-conveying pipe; an input end of the controller is electrically connected with the soil humidity sensor and the temperature sensor; and an output end of the controller is connected with the flow regulating valve.The water-spraying device and method for public greening have following beneficial effects: average flow required for each time of water spraying can be calculated in a real-time manner; the water quantity is controlled for spraying water in a continuously and periodically changing manner; on the condition that a requirement for public greening is satisfied, the water spraying quantity is decreased for more than 70%; water resources are greatly saved; and therefore the water-spraying device and method are especially suitable for a water shortage region.

Description

technical field [0001] The invention relates to the field of sprinkler equipment, in particular to a sprinkler equipment for public greening. Background technique [0002] Urban landscaping, as a basic construction industry in the city, is an indispensable and important part of urban environment construction, and is playing an important role in promoting the implementation of urban sustainable development strategies. The equipment for watering plants in landscaping is one of the commonly used equipment for landscaping workers. The existing long-used water gun is a water nozzle. Sprinklers, most of these sprinklers only spray water according to their own set fixed rules, or someone manually controls the water spray time and water spray volume. The water spray volume in this way has not been precisely optimized, which is unreasonable. When it is fast, the amount of regular water spraying may not be able to meet the requirements, and when the temperature is low, it may not be ...

The equipment for watering plants in landscaping is one of the commonly used equipment for landscaping workers. The existing long-used water gun is a water nozzle. Sprinklers, most of these sprinklers only spray water according to their own set fixed rules, or someone manually controls the water spray time and water spray volume. The water spray volume in this way has not been precisely optimized, which is unreasonable. When it is fast, the amount of regular water spraying may not be able to meet the requirements, and when the temperature is low, it may not be necessary to spray water at all. When it rains temporarily, the soil itself has sufficient moisture, so there is no need for water spraying; the regular water spraying in the prior art Setting will inevitably cause waste of water resources;

[0003] In addition, due to the structural problems of the nozzle itself, there is usually a dead angle of water spray in the area close to the nozzle, resulting in an area around the nozzle itself that cannot directly contact the water. Only by increasing the amount of water sprayed to completely saturate the entire green area can the nozzle be avoided. The greening of the location does not lack water, which further wastes water resources; it is not suitable for use in areas lacking water resources
