The present invention relates to a waterside installation type non-powered green algae suction device, and more particularly, is installed on watersides such as rivers, lakes, reservoirs, dams or weirs where water pollution due to algal blooms is frequent due to stagnant water flow, and particularly A non-powered waterside installation type that sucks green algae containing green algae from the surface of the water by applying the siphon principle and then continuously pulls it down to a low point on the waterside lower than the water surface to suck in and remove the algae containing green algae. It relates to an algae water inhalation device.

Green algae refers to a phenomenon in which green algae and blue-green algae greatly increase in eutrophic lakes or slow-flowing rivers, and the color of the water becomes green. In the case of slowed down, a large amount of algae is generated.

In particular, in the case of Korea, most of the rivers and lakes are in a mesotrophic or eutrophic state, so the possibility of algal bloom is very high, and algal bloom damage is a chronic problem suffered during the high temperature period in summer. As a result, a huge amount of budget and effort is invested every year, and it is expanding as a social problem that causes people to distrust drinking water, centered on water sources.

Conventionally, a method of removing algae by spraying an algae removing agent such as coagulant, microorganism, or loess has been implemented as a method of removing the algae, but the method of removing the algae by spraying the algae removing chemical deteriorates the water quality of Suho. There are problems that can be made, so there is a limit to applying this method to the waterside located in the water source.

As an alternative to this, in the case of the water source area, a method of searching for and removing algae algae using a ship-shaped movable algae removal vessel is being implemented, but the method of connecting power cables or replacing batteries is Not only is it difficult to supply sufficient power, but it is difficult to fix the hull when necessary, such as working on the water, and maintenance costs are high, such as requiring several operating personnel, but the algae removal efficiency is low, preventing algal bloom in a wide area. There was an operational limit to continuous removal.
