Description

DRONE FOR COLLECTING WATER TRASH

The present invention relates to a water garbage collection drone for collecting water garbage caught in a structure of a dam or a weir.

Dams and weirs are constructed to store water, prevent soil runoff, water intake, increase water level, or prevent collapse by crossing mountain valleys or rivers.

Depending on the material, there are wooden dams using wood, rockfill dams using coarse-grained materials, earth dams using soil, and concrete dams using concrete.

Timber dams were used in the early days of the Industrial Revolution and are recently constructed for temporary use for easy and fast construction.

Because the rockfill dam is made with compacted materials, the watertightness is poor, so a separate water-impermeable layer is installed.

The soil dam is similar in principle and construction method to the rockfill dam, but since it is constructed with evenly-grained soil, a separate drainage hole is installed.

Concrete dams include gravity dams and arch dams.

Gravity dams are dams made to withstand water pressure by gravity due to the weight of the structure itself. Since the moment force due to the weight of the dam structure itself is greater than the moment due to the water pressure acting on the dam, it can withstand the water pressure without being conducted. In other words, it should be designed so that the resultant force of the force by water pressure and the force by its own weight is located in the bottom part of the dam.

Arch dam is a type of dam that secures stability by gravity and arch effect by its own weight. Enduring water pressure by gravity by its own weight is the same principle as gravity dam, and the arch effect receives water pressure and decomposes the force in both eyes where the dam is located, resulting in the effect that less load is transmitted to the foundation

In Korea, most of these types of dams are being constructed for the purpose of preventing soil runoff from mountain streams, where sediment runoff is in progress, and for preventing damage to agricultural land downstream.

On the other hand, aquatic garbage may float on the surface of a dam or a weir, and such aquatic garbage may be collected by a floating drone that floats on the surface of the water.

By the way, a screen is installed in the intake or drain port of a dam or weir to filter water garbage contained in the water flowing from upstream to downstream. Since it had to be collected, there was a problem in that it was difficult to collect the water waste.
