Description

Precise and efficient artificial rainfall method and system for smart grid supporting cabled helicopter platform

technical field

The invention relates to an artificial rainfall method, in particular to a precise and efficient artificial rainfall method and system for a smart grid to support a cabled helicopter platform.

Background technique

As the global temperature warms, the ground temperature will inevitably rise, the evaporation intensity of land water will increase, and the water storage capacity of the land will also weaken, and the natural water shortage caused by the warming will inevitably increase accordingly. At the same time, with the advancement of urbanization, a huge number of people living in rural areas have changed from a rural lifestyle that requires very little water to an urban lifestyle that requires a lot of water. It needs to be flushed, and after moving to the city, it is necessary to use a flush toilet. Originally, the wastewater discharged from rural life can be recharged to groundwater through stratum filtration, and the wastewater discharged after migrating to the city can only be discharged into the sea through urban drainage channels. Moderate rainfall can be recharged to groundwater through natural infiltration of the bare surface. After migration, rainfall in urban residential areas cannot infiltrate and filter and purify underground, and precipitation can only be discharged into the sea through urban flood discharge and sewage channels, etc., making water shortage even worse. for serious. There are only two ways to solve the problem of water shortage, one is open source, and the other is throttling. Water saving is a complex and gradual systematic project, and there will be no significant effect in a short period of time. The only way to solve the problem of water shortage in time is open source. The cost of water transfer from different places is high, and the amount of water transferred is very limited, which is far from meeting the needs; the cost of seawater desalination is high, and it is not economically feasible. Although the increase or decrease of workers is not limited by surface water resources, it is inexhaustible and inexhaustible. However, rockets or cannons use artillery shells to spread rain-increasing agents, the cost of launching ammunition is high, the shells often need to be recycled, the area of rain-enhancing is very limited, the requirements for cloud layers are high, the utilization rate of rainfall agents is low, and the rainfall effect is poor, which is far from being widely promoted. Application; among them, the aircraft sow the rain-increasing agent, although the requirements for the cloud layer are low and the rainfall effect is good, but because of the high cost, it can only be used in rare special cases that do not require cost calculation.

In extremely arid deserts and the arid northwest plateau with little rainfall, clouds rich in supersaturated water vapor often float in the sky, especially in some perennial arid areas. Due to special geographical, landform and climatic reasons, although clouds often float by , but rainfall is extremely rare. Due to the small area and thickness of the cloud layer, the existing rocket launchers suitable for large and thick cloud layers cannot be used to increase rainfall due to poor accuracy and poor rainfall effect, and cannot be used. The amount is too small, the cost-effectiveness is too poor, and it is not applicable. Therefore, there is an urgent need for a new rainfall technology that can perform low-cost, accurate and efficient rainfall enhancement operations on thin cloud layers and scattered clouds.
