Ultraviolet water sterilization
View Patent ↗Technologies are generally described about a water sterilizing apparatus. In some examples, a water sterilizing apparatus may include a surface water collection apparatus configured to collect surface water; a pipe operably coupled to the surface water collection apparatus and configured to allow water collected by the surface water collection apparatus to flow through the pipe; and a multiple number of UV lamps arranged along an inner wall of the pipe. Further, the water flowing through the pipe is sterilized by UV light from the multiple number of UV lamps.

7. The water sterilizing apparatus of claim 1 , wherein the pipe is formed in a spiral shape.
8. The water sterilizing apparatus of claim 1 , wherein the inner wall of the pipe is configured to reflect the UV light from the plurality of UV lamps.
9. The water sterilizing apparatus of claim 1 , wherein the plurality of UV lamps are arranged in a spiral shape along the inner wall of the pipe.
10. The water sterilizing apparatus of claim 1 , wherein the plurality of UV lamps are arranged so as to face each other along the inner wall of the pipe.
11. The water sterilizing apparatus of claim 1 , wherein the water is rainwater.
12. The water sterilizing apparatus of claim 11 , wherein the surface water collection apparatus is provided on a roof.
13. The water sterilizing apparatus of claim 11 , wherein the surface water collection apparatus is provided on a wall of a structure.
14. The water sterilizing apparatus of claim 1 , wherein the floating object is a floating ball.
15. A water sterilizing apparatus comprising:
a surface water collection apparatus configured to collect surface water;
a pipe operably coupled to the surface water collection apparatus and configured to allow water collected by the surface water collection apparatus to flow through the pipe, wherein the pipe is transparent to UV light; a plurality of UV lamps arranged along an outer wall of the pipe and configured to emit UV light to sterilize water flowing through the pipe;
a partition wall provided within the pipe and having a hole therein; and
a floating object positioned on the hole and configured to be floated by water flowing through the pipe.
16. The water sterilizing apparatus of claim 15 , further comprising:
an outer pipe configured to surround the pipe and the plurality of UV lamps, wherein the outer pipe is non-transparent to the UV light.
17. The water sterilizing apparatus of claim 16 , wherein an inner wall of the outer pipe is configured to reflect the UV light from the plurality of UV lamps.
18. The water sterilizing apparatus of claim 15 , further comprising:
a filter positioned upstream of the plurality of UV lamps and configured to filter the water collected by the surface water collection apparatus.
19. The water sterilizing apparatus of claim 15 , further comprising:
a container operably coupled to the pipe and configured to store the water that has flowed through the pipe.
20. The water sterilizing apparatus of claim 15 , wherein a cross-sectional area of a portion of the pipe where the floating object is positioned is larger than a cross-sectional area of another portion of the pipe.
21. The water sterilizing apparatus of claim 15 , wherein the pipe branches into a plurality of passages, wherein at least one of the plurality of UV lamps is arranged along an outer wall of each of the plurality of passages.
