Disclosed are: a hull of which the bottom has a streamlined shape, and which moves while floating on the surface of water by the driving of a motor; moving screws respectively provided at both sides of the hull so as to enable the hull to move on the ground; a cutting part provided at the stem so as to cut water weeds in the water and transfer the cut water weeds to the hull; a lift for adjusting the angle and height of the cutting part; and a control part for controlling hull movement, the cutting part, and the lift. The present invention includes the cutting part, which is provided in the hull floating on the surface of the water and submerged at a predetermined water depth, so as to cut the water weeds exposed at the surface of the water, collect the cut water weeds, and directly or indirectly transfer the collected water weeds to the ground, thereby enabling an effect of preventing water pollution caused by the water weeds to be expected.

Abrégé

The present invention relates to a stirring device for water treatment. The stirring device for water treatment includes: a driving part including an impeller rotated by a driving motor and a first floating part for preventing the motor from being immersed; an inflow part, which is a tube body vertically immersed within a water area, through which foreign substances deposited on a bottom of the water area are suctioned by the rotation of the impeller; a discharge part disposed between the driving part and the inflow part to discharge the foreign substances suctioned from the inflow part toward an upper portion of the water area, the discharge part including at least one second floating part so that the stirring device is adjusted in height to correspond to the discharging region and a change of a water level. In the stirring device, floating parts having adjustable buoyancy may be provided so that the stirring device is stably installed in a water treatment plant as well as open spaces such as a stream, a reservoir, a river, the sea, and the like. Also, the stirring device may be balanced and adjusted in buoyancy by means of the floating parts to correspond to the change of the water level. Also, the foreign substances in various depths may be selectively discharged through the floating parts to more efficiently perform the stirring process. Thus, water within a polluted water area may be easily purified. Also, since the stirring device can be installed in open spaces, water within various polluted areas may be purified. In addition, since the driving part of the stirring device is exposed through the floating parts, it may prevent the driving part from being immersed, and also safe working above a water surface may be possible to improve maintenance efficiency of the device.

The present invention relates to a water circulating device using solar light which is installed in a park or lake to circulate water, thereby purifying the water. The water circulating device includes: an expandable corrugated tube unit for introducing water within a water area to diffuse the water toward an upper portion of the water area; a unit frame for supporting the expandable corrugated tube unit; a plurality of barge units for providing buoyancy to the expandable corrugated tube unit and the unit frame; an impeller for dispersing water within the expandable corrugated tube unit to the outside of the expandable corrugated tube unit; and a rotation power supply unit for supplying a rotating power to the impeller.

Provided is a water circulation device. The water circulation device comprises: a corrugated draft tube including a main body which has a hollow cylindrical shape, and which is arranged in a water area, a main inlet port which is formed in a lower end of the main body to enable water stagnating in a lower layer of the water area to be fed therethrough, a plurality of sub-inlet ports which are formed at a side wall of the main body to enable water adjacent to the side wall to be fed therethrough; and a diffusion portion formed on the top of the main body to discharge the fed water to an upper layer of the water area adjacent to the top of the main body. Water fed into the draft tube is discharged to the upper layer of the adjacent water area via the diffusion portion by an impeller which rotates in a predetermined direction by means of a driving motor. Thus, water in the water area circulates in an efficient manner, and the formation of a dead zone is prevented.
