Abstract

PURPOSE:To automatically clean the surface of liquid by a method in which a hollow container is set to be immersed in a stored liquid, a filter to arrest dust in the liquid is set in the container, and a pump to discharge the liquid to the outside of the container is also provided. CONSTITUTION:A liquid 2 stored in a pool is directed through the weir side 3b of a hollow container 3 into the water region 6 of the container 3. In this case, dust floating on near the surface of the stored liquid is arrested into the region 6, and the coming liquid is filtered through the filter 9 to remove dust in the liquid. The liquid so clarified is directed into a drain region 7 and discharged to the outside of the container 3 by a drain pump 11, where the liquid is forcibly circulated repeatedly between the bottom of the surface of the liquid 2 for cleaning the whole of the liquid 2. The cleaning operation can thus be automatically made without resorting to hand.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a liquid surface cleaning device used for liquid tanks such as pools and ponds that store liquid.

(Prior art) Conventionally, when removing and cleaning dirt and dust (hereinafter referred to as dust) floating near the liquid surface of a liquid stored in a liquid tank such as a pool or pond, it is necessary to clean the liquid tank. By installing a filtration device outside and circulating the liquid in the liquid tank by introducing it into the filtration device, or by manually operating a rod with a net attached to the end, the level of the accumulated liquid can be reduced. Efforts are being made to remove dust from the vicinity.
