Abstract

本发明公开了一种无接地飞行器带电粒子播撒平台，属于人工影响天气领域。播撒带电粒子的飞行器需要持续不断的向外部发出电荷，如果没有地线对电荷进行中和，会造成电子的流失和正电荷的累积。本发明利用带电粒子发生模块对外分别发出正、负电荷，并通过电源控制模块对流向带电粒子发生模块中正负电极的电流大小进行监测，在保证功率尽可能大的前提下调节高压电源的电压，使正、负电极的电流值始终可以保持动态平衡，以免除地线。由于飞行器不再受接地牵引件和地线的限制，可以在开阔的空间中大面积进行带电粒子播撒，提高了电催化降雨、空气净化与消雾等任务的灵活性与作用效果。

The invention discloses a groundless aircraft charged particle spreading platform, which belongs to the field of artificial weather modification. An aircraft that spreads charged particles needs to continuously emit charges to the outside. If there is no ground wire to neutralize the charges, it will cause the loss of electrons and the accumulation of positive charges. The invention utilizes the charged particle generating module to send out positive and negative charges respectively, and monitors the magnitude of the current flowing to the positive and negative electrodes in the charged particle generating module through the power control module, and adjusts the voltage of the high-voltage power supply on the premise that the power is as large as possible , so that the current value of the positive and negative electrodes can always maintain a dynamic balance to avoid the ground wire. Since the aircraft is no longer restricted by grounding traction parts and ground wires, it can spread charged particles in a large area in an open space, which improves the flexibility and effect of tasks such as electrocatalytic rainfall, air purification and fog elimination.

Description

Platform is scattered to electrified particle of no ground connection aircraft
Technical Field
The invention belongs to the field of artificial influence weather, and particularly relates to a charged particle scattering platform of an ungrounded aircraft.

The electrocatalytic rainfall is a method for promoting the formation of rainfall by electrifying part of aerosol in the air, generating an electrostatic field to have a polarization effect on other neutral water molecule clusters, generating non-contact electric field condensation force of electrified aerosol particles on the polarized water molecule clusters, and promoting the condensation rate of the water molecule clusters to increase. According to the same principle, the air purification and fog dissipation tasks can be carried out.
However, two existing techniques for scattering charged particles, that is, scattering charged particles by using a discharge device and scattering charged particles by using diffusion or natural airflow, are fixed in one position, and have a limited range and are greatly influenced by geographical locations and natural environments; or the aerial vehicle is utilized to directly enter a cloud layer or an area needing to be scattered with the charged particles for scattering, although the charged particles can be scattered in a wider space, the charged particles can also be directly scattered to a specified position, but the aerial vehicle is often matched with a traction piece and a ground wire on the ground, and if the ground wire is not arranged, the charges generated on the aerial vehicle are accumulated, so that the charged particles cannot be scattered.
The two technologies greatly limit the range of charged particle scattering in the application of an external field, have higher requirements on ground conditions, and limit the flexibility and action effects of tasks such as electro-catalysis rainfall, air purification, fog dissipation and the like.
