Description

[Detailed Description of the Invention] The present invention relates to a float valve used to remove oil, dirt, etc. floating on the surface of water.

Conventionally, this type of float valve has been a large type with a water suction pump suspended in water by a float such as a drum can. Such large vessels require a power source, conductive wires, etc., and are extremely complicated to handle on the water.

The purpose of the present invention is to improve the above-mentioned conventional drawbacks and provide a float valve that is small and simple in structure.
Therefore, the present invention provides a notch in the upper edge of a cylinder made of a material whose specific gravity is lighter than water, and loosely fits into the inside of the cylinder an intake tube that fixes the wing body and is fixed underwater. The main feature is that a discharge pipe is connected to the bottom of the intake cylinder.

The present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a cylindrical body made of a material lighter than the specific gravity of water, such as polyethylene, polypropylene, polyvinyl chloride, or wood. Notch 2 on the upper edge of the cylinder 1
is provided. The depth of the cut 2 is adjusted so that when the float valve floats on water, the bottommost part 2A of the cut 2 is located slightly below the water surface. For the above adjustment, it is preferable to make the notch 2 or to wrap the wire 6 or the like around the lower part of the cylindrical body several times. Reference numeral 4 denotes a support frame extending from the upper edge of the cylinder 1, and a fixed shaft 4B is suspended from the center of the upper frame 4A of the support frame 4.
A wing body 4C is fixed to the lower end of. 3 is the lower base 3A
It is an intake cylinder having a lower bottom 3 of the intake cylinder 3, which is fixed in water and loosely fitted into the cylinder body 1.
A discharge pipe 5 communicates with A. The intake tube 3 does not necessarily need to be made of a material with a specific gravity lighter than water, and may be made of metal or the like.

Further, the upper edge of the intake cylinder 3 must be located below the bottommost part 2A of the notch 2 of the cylinder body 1.

When the cylinder 1 having the above structure is floated on water around the intake cylinder 3, the bottom 2A of the notch 2 of the cylinder 1 is located slightly below the water surface, so that the water near the water surface is filled with oil, dirt, etc. It flows into the cylindrical body 1 through the notch 2 together with the floating matter. At this time, the water flow flowing into the cylindrical body 1 is applied to the blade body 4C, so that the blade body 4
The cylindrical body 1 rotates through C, and water near the water surface is scraped off by the cuts 2 together with floating objects. Furthermore, the notch 2 is prevented from being clogged with dirt, bubbles, etc. Most of the water that has flowed into the cylinder 1 flows into the intake cylinder 3 as shown by the arrow in FIG. 1 and is taken out of the system via the discharge pipe 5. A pump, a suction device, etc. (not shown) may be connected to the discharge pipe 5.

In this embodiment, the cuts 2 in the cylinder 1 are made into a wave shape, but they may be in any other shape such as a sawtooth shape, and the cuts 2 do not necessarily have to be formed over the entire circumference. Further, the intake tube 3 may be formed into a funnel shape or may have any other arbitrary shape.

As mentioned above, in this invention, a notch is provided in the upper edge of the cylinder made of a material whose specific gravity is lighter than water. The notch 2 is always located at an appropriate position below the water surface, so water near the water surface selectively flows into the cylinder through the notch, and the wing body is fixed inside the cylinder. Because of this, the flow of water flowing into the cylindrical body is applied to the wing body, causing the cylindrical body to rotate through the wing body, resulting in a state in which water near the water surface is scraped off by the notch along with floating matter, For example, even if highly viscous oil is floating on the water surface, the oil will smoothly flow into the cylinder. Furthermore, such rotation effectively prevents clogging with cutting debris, bubbles, etc.

Furthermore, since the intake cylinder is fixed inside the cylinder, most of the water that has flowed into the cylinder flows into the intake cylinder and is taken out of the system through a flexible pipe connected to the bottom of the intake cylinder. Thus, with the float valve of the present invention, which has an extremely simple structure and is easy to downsize,
Water near the water surface can be smoothly removed along with floating objects. Furthermore, the depth below the water surface to which water can be extracted can be determined in any way by adjusting the depth of the cut in the cylinder.
