Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical pointing float. Conventionally, the difference in weight between the float and the liquid displaced due to the capacity of the float itself was used as buoyancy, resulting in a large volume and large equipment weight.

This invention improves the efficiency of the float by creating an upper chamber and a lower chamber in the liquid container on the outer periphery of the float to generate a pressure difference.

The present invention will be described below with reference to the drawings.

Sealed transparent support frame cylinder 1 and upper sealed liquid container 2
Fill the container with liquid up to the water level 12, turn the top-shaped container 4A upside down, connect the string or rod 6 with a hinge connection 6A to the lower part of the trunk 4B integrated with the top, and connect the lower end of the string. A hinge 6B is connected directly above the target point 3 which also serves as a support frame, the lower airtight chamber 7 is opened, and the water level difference (approx.
20cm water pressure)/-atmosphere (approximately 1000cm water pressure) to lower the air pressure in the upper airtight chamber 11 and close the airtight plug 10, or open the upper airtight plug 10 and supply pressurized air from the lower airtight plug 7 to reduce the lower air pressure. By increasing the air pressure in the closed room 8 by the water level difference/-atmospheric pressure, the water surface outside the float 1
3 A water surface 14 inside the float is created, which is the same as when liquid was removed at the outer periphery of the reverse tip, and the inside of the tip is removed from the trunk 4B.
Although the weight of the support frame 1 affects the buoyancy, the buoyancy is generated regardless of the fact that the upper part of the support frame 1 does not occupy the inside of the coop. In addition, when the outer circumferential capacity of the tip 4A is larger than the liquid 5, an efficient float is obtained in which the buoyancy is greater than the weight of the entire device containing the liquid. Further, buoyancy is generated by subtracting gravity, and the vertical line of buoyancy including the entire floats 4A and 4B geometrically always passes through the hinge 6A, so the vertical indicator 6 is always vertical. In that case, the upper liquid container 2 of the support frame 1 does not necessarily need to be held vertically, but if it is held roughly by hand or the like to the extent that the float and the container do not come in contact with each other within the margin width 5 where the liquid is present, the vertical marking section 6 will be corrected by the error. It becomes vertical. In addition,
When the upper stopper 10 is opened, the upper airtight chamber 11 may not be provided, and the shape thereof is free. When the lower stopper 7 is opened, the lower airtight chamber 8 may be omitted, and the support frame 1 may have any shape, and does not need to be a transparent container, but may be rod-shaped.

As explained above, this invention differs from conventional floats in that regardless of other equipment occupying the inside of the float, the space in which the bottom-open container excludes liquid becomes buoyant, and the buoyant force is greater than the total weight of the float, including the liquid. It is a vertically directed float that can create floats that can also generate.

[Brief explanation of the drawing]

Fig. 1 is a plan view, and Fig. 2 is a side view. 1 is a sealed lower transparent support frame cylinder, 2 is a sealed upper liquid container, 3 is a target indicator, 4A is a floating body tipped inverted container, 4B is a trunk integrated with the floating body, 5 is an extra width for storing liquid, 6 6A and 6B are the hinge joints, 7 is the lower chamber airtight plug, 8 is the airtight space inside the transparent airtight support frame made by 1 and 7, and 9 is the vertical marking part that connects the lower end with the float. 10 is the upper room airtight plug, 11 is the upper airtight space created by 2 and 10, 12 is the water surface when no pressure difference is generated, 13 is when the pressure difference is generated. 14 is the water surface on the outside of the float, and 14 is the water surface on the inside of the float when a pressure difference is generated.

Claims (1)

[Claims] 1 Put a liquid into a sealed transparent support frame cylinder 1 and an upper sealed liquid container 2, turn the top-shaped container 4A upside down, and attach a string 6A hinged to the lower part of the trunk 4B integrated with the top. By hinge-coupling the rod directly above the target pointing point at the bottom of the support frame and lowering the air pressure in the upper airtight chamber 11 or increasing the air pressure in the lower airtight chamber 8, a water level difference is created between the outside and inside of the inverted tip, and the tip is lowered. Buoyancy is generated and the outer containers 1 and 2
If the float 4A and the liquid container 2 are not necessarily held vertically but roughly held within the margin 5 where the liquid exists to the extent that the float 4A and the liquid container 2 do not come into contact with each other, the vertical indicator part 6 becomes vertical without error.
