Collecting Apparatus of Biological Material for Mounting on Remotely Piloted Vehicle}

The present invention relates to a device for collecting biological material present in the air by using an unmanned aerial vehicle, and more particularly, to mount the collection device to the drone, for mounting the drone for collecting the biological material contained in the air in the liquid phase It relates to a biological material collection device.

Examples of devices that collect particles in the air, particularly biological particles, are the Virtual Impactor (US 7,325,465) and the Cyclone Sampler (US 5,855,652, US 5,902,385, US 6,851,459).

Impactors are classified according to particle size and are widely used to facilitate chemical analysis of each size. The working principle of the impactor is that the air containing particles collides with the impact plate at a high speed as it passes through the nozzle, and in the event of the collision, the air escapes to the side through the collision plane, Particles hit the collision plane and use the principle that their inertia forces them to collect with the air rather than escaping to the side of the collision plane.

Unlike conventional impactors with impact planes, a virtual impactor is a type of impactor that eliminates the impact plane and allows particles above a certain moment of inertia to be naturally captured and moved downward. By eliminating the collision surface, it is possible to reduce the wall loss (wall loss) to increase the separation efficiency and to reduce the contamination of the fine particles.

Virtual Impactor is advantageous in that it can decompose particle size, but in that configuration, the Impact Disk must be carefully assembled to satisfy its performance. ) Also has the disadvantage of being heavy due to steel (Steel), and the system is complicated because the exhaust port must be provided for each floating step. In addition, it is necessary to precisely adjust the disk spacing according to the capacity of the blower to ensure proper performance.

On the other hand, the Cyclone Sampler cannot distinguish the size of the particles of the Virtual Impactor, but the structure is much simpler. However, these two types of collectors must be equipped with a blower capable of blowing at least 500 liters of air per minute, which cannot be adapted to the payload of an unmanned aerial vehicle. And even if possible, the power consumption by the blower (Blower) is so large that it can not be mounted on the drone.

Therefore, the above two types of collection devices are limited to the range of the collection area because they are manufactured only in a fixed vehicle type, and cannot be maneuverable. There are some limits to the prediction.

If toxic biological material is sprayed during the war or in the environment, it must be collected immediately and analyzed at high concentrations to reduce many losses. Therefore, as a collecting device for wartime or general use, it is mounted on unmanned means of flight (US 7,073,748) and collects frequently in a short period of time, especially in the vicinity of the suspected area, to predict the proliferation of biological weapons and to take measures.
