Problems solved by technology

In the current sprinkler irrigation technology, there are still many problems to be solved for the uniformity of sprinkler irrigation: 1. Due to the difference in the distance between multiple sprinklers and their combination forms, the superposition of the sprayed water volume of two adjacent sprinklers is different, which will affect the distribution of sprayed water volume. influences
2. Due to the hydraulic performance of the nozzle itself, the amount of water sprayed by a single nozzle is unevenly distributed on the ground surface
3. Due to the loss of water head in the pipeline and the height difference of the terrain, the working pressure of each nozzle is inconsistent, that is, the working pressure deviation of the nozzle
4. Due to the influence of the slope of the terrain on the water distribution of a single nozzle
5. The uniformity of sprinkler irrigation is closely related to the investment of the sprinkler irrigation system. The system investment increases with the increase of uniformity. When the uniformity of sprinkler irrigation is greater than 90%, a slight increase in the uniformity of sprinkler irrigation will lead to a rapid increase in the cost of the sprinkler irrigation system.
6. When the wind speed exceeds level 3, the use of sprinkler irrigation technology will lead to a very serious drift loss of spray droplets during the spraying process, which will reduce the water use efficiency of sprinkler irrigation technology, so it is not easy to use sprinkler irrigation for irrigation
However, in this invention, the solution to the uniformity of crop spraying is not mentioned, and the device is not equipped with a rain collection device, so the water saving effect is not obvious

Description

technical field [0001] The invention relates to a sprinkler irrigation device capable of collecting rain for irrigation in a greenhouse, belonging to the technical field of agricultural irrigation. Background technique [0002] The shortage of water resources has become an important factor restricting the sustainable development of my country's agriculture and national economy, and agricultural water-saving irrigation is imperative. At present, my country's agricultural water-saving irrigation methods are mainly divided into three types: traditional surface irrigation, ordinary sprinkler irrigation and micro-irrigation. Among them, sprinkler irrigation technology has become one of the widely used water-saving irrigation technologies in the world due to its advantages of wide adaptability and easy mechanization. [0003] Sprinkler irrigation is a method of using special equipment to send pressurized water flow to the irrigation area and spray it through the sprinkler head. ...
