Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a water tank which floats on the upper surface of various water tanks so as to cover the liquid surface so that oxygen in the air dissolves in water such as a boiler water supply tank and vaporizes oil (for example, The present invention relates to a float for liquid surface coating which prevents gasification of gasoline and the like and emission of odor from a treatment tank of a wastewater treatment plant.

2. Description of the Related Art As a float for coating a liquid surface, a honeycomb-shaped hollow side surface, a hollow convex upper surface which covers the above hollow side surface, a convex upper surface which is asymmetric and has a thickness of the convex upper surface. Japanese Patent Application Laid-Open No. 51-90021 discloses a thicker lower surface which is thicker than a wall and closes the bottom of the hollow side surface.

[0003]

The above-mentioned known floats are:
When floating on water, the liquid surface is always on the honeycomb-shaped hollow side surface, and many of these hollow side surfaces are circumscribed and float on the water, so that the liquid surface can be covered without gaps. However, since the convex upper surface is a spherical surface with a large curvature and a low height, or a conical surface with a low height, it is overlapped by the flow of water or the wind and floats on the water. A part that does not cover the liquid surface due to waste that rides and does not perform the coating function of the liquid surface at all, or interrupts a little between a plurality of floats that are circumscribing and covering the liquid surface to prevent circumscription. May be caused. Also, when the float is placed on the liquid surface, care must be taken to prevent the float from overlapping as described above.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems of the conventional float.
The convex upper surface closing the upper surface of the honeycomb-shaped hollow side surface is provided with an inclination of 45 ° or more with respect to the upper portion of the hollow side surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In each of the illustrated embodiments, 11
Is a honeycomb-shaped hollow side surface, 12 is an integral hollow convex upper surface closing the upper surface of the hollow side surface, 13 is asymmetric with the convex upper surface, and has a thickness greater than the wall of the convex upper surface. This figure shows an integral thick lower surface that closes the lower surface of the side surface.
1. The float 10 for covering a liquid surface, which is composed of a convex upper surface 12 and a thick lower surface 13, is formed of a synthetic resin or a corrosion-resistant metal. At this time, the wall 20 of the hollow side surface 11 is made vertical along the vertical direction of the float 10, and the wall 22 of the thick lower surface 13 is configured to be thicker than the wall 21 of the convex upper surface 12. The thickness of the wall body 22 of the thick lower surface 13 is determined when the float 10 is floated on the liquid surface in consideration of the material constituting the wall, the specific gravity of the liquid covered by the float 10, the weight of the convex upper surface, and the like. , So that the liquid level comes to the hollow side surface 11. Therefore, even when the float 10 is dropped on the liquid surface, the float 10 rises even when the convex upper surface is directed downward, so that the float 10 is turned upside down like a small priest and the convex upper surface is turned upward. When floating on the surface, the liquid level is always on the honeycomb-shaped hollow side,
As shown in FIG. 2, six floats around one of the six sides of the honeycomb-shaped hollow side of the center one float are adjacent to one side of the honeycomb-shaped hollow side, and seven The liquid surface can be covered without any gap by using the float circumscribed as a unit.

The structure of the hollow convex upper surface 12 is shown in FIG.
As shown in FIGS. 1A and 1C, the shape may be a pyramid, for example, a hexagonal pyramid, or a part of a sphere such as a hemisphere as shown in FIGS. 1B and 1D.

The structure of the thick lower surface 13 is shown in FIG.
The shape may be a horizontal plate as shown in (D), a downward conical shape as shown in FIG. 1A, or a part of a downward spherical shape as shown in FIG. 1B. In FIG. 1A, the hollow convex upper surface 12 has a hexagonal pyramid shape, and the thick lower surface 13 has a hexagonal pyramid shape, but the thick lower surface may be part of a sphere as shown in FIG. 1B. Similarly, in FIG. 1B, the hollow convex upper surface 12 is a part of a sphere,
Similarly, the thick lower surface 13 is formed as a part of a sphere, but the thick lower surface may have a conical shape as shown in FIG. Thick bottom surface 13
Is convex downward as shown in FIGS. 1A and 1B, the downward length h of the convex is preferably smaller than the height H of the convex upper surface 12. In any case, the thick lower surface 13 is made asymmetric with respect to the convex upper surface 12.

The convex upper surface 1 connected to the upper end of the hollow side surface 11
The lower end of 2 has an elevation angle α of 45 ° or more, preferably 60 °, with respect to the upper part of the hollow side surface.

As described above, the elevation angle 4
Since a slope of 5 ° or more is provided, as described above, it is circumscribed, floats on the liquid surface, and covers the liquid surface without gaps.
Anything that is floating in the liquid due to the flow of water or the wind, even if you try to overlap on top of it, because the lower end of the convex upper surface of the lower float is inclined at an elevation angle of 45 ° or more. When I try to get on, I slip down and cannot overlap.

[0010]

As is evident from the above, according to the float of the present invention, the float floating on the liquid surface cannot be placed on the liquid surface and cannot be overlapped on the liquid surface. Does not occur, and what breaks in between the floats circumscribing and covering the liquid surface slides down on the liquid surface due to the inclination of the convex upper surface of the surrounding floats, The float is displaced and circumscribed, and together they cover the liquid surface. In addition, there is no need to take care that the floats do not overlap when being charged into the liquid surface.
