Abstract

PURPOSE:To enable a floating body to float underwater or on the surface of water with an inexpensive and simple structure by constituting so that when gas is filled inside a main float part, a buoyancy smaller than the weight of an apparatus is generated, and that when gas is filled inside an auxiliary float part, a buoyancy greater than the weight of the apparatus is generated due to the addition to the buoyancy of the main float part. CONSTITUTION:When a buoyancy smaller than the weight of an apparatus 5 is generated by the gas 7 supplied inside a main float part 1, the whole apparatus floats in the water. Next, when gas 7 is supplied inside an auxiliary float part 2 through a buoyancy regulating valve 3, a buoyancy greater than the weight of the apparatus 5 is generated due to the addition to the buoyancy of the main float part 1, and the whole apparatus rises in the water. Then, when the auxiliary float part 2 floats above the surface of water, the gas 7 inside the auxiliary float part 2 is discharged into the outside air in a quantity much greater than that supplied through the buoyancy regulating valve 3, and accordingly the gas 7 inside the auxiliary float part 2 decreases, so that the whole apparatus falls quickly in the water. The above action is repeated. And when the gas 7 inside a gas supply part 4 is exhausted, the whole apparatus automatically sinks.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an underwater floating device that holds audio equipment and floats on the water, and particularly relates to an underwater floating device that is suitable for constantly floating below the water surface. .

[Conventional technology]

In conventional underwater floating devices, a depth sensor is installed on a float with glass buoyancy, and the buoyancy of the float is adjusted by controlling the amount of gas supplied within the float, thereby causing the float to float below the water surface. [Problems to be solved by the invention] In the above-mentioned conventional technology, first of all, the price increases, and if the gas supply amount is not controlled in conjunction with the depth measurement result of the depth sensor, It either scuttles or floats on the surface of the water.

Ninth, in the case of scuttling, the function as a floating device will no longer work, and if it remains floating on the water surface, it will be easily discovered, so if it is necessary to avoid this, for the purpose cannot be achieved.

An object of the present invention is to provide an underwater floating device that is inexpensive to manufacture, has a simple configuration, automatically floats in water, and can reduce the time spent floating on the water surface.

[Means for solving problems]

The purpose of the above is to provide a main float part that is open at the bottom and holds equipment, a sub-float part that is installed above the main float part and is open at the bottom, and a buoyancy adjustment pipe that connects inside both of these float parts. , a gas supply section that is installed in the main float section and supplies gas by reacting with water; when the main float section is filled with gas, a buoyant force smaller than the weight of the equipment is generated, and the buoyant force is This is achieved by configuring so that when the sub-float section is filled with gas through the adjustment pipe, a buoyancy force greater than the weight of the equipment is generated in combination with the buoyancy force within the main float section.

[Effect]

In the underwater floating device according to the present invention, when a buoyant force smaller than the weight of the device is generated by the gas supplied into the main float section, the entire device floats in the water.

Next, gas is supplied from the buoyancy adjustment pipe into the sub-float section to generate a total buoyant force in the sub-float section, which is greater than the weight of the equipment, which is the sum of the buoyancy within the main float section, and the entire device rises in the water. In this case, gas is released into the water from the opening of the side float, but since the area near the opening is located underwater, the amount of gas released into the water at the opening due to water resistance is limited by the amount of gas released into the water from the buoyancy adjustment pipe. smaller than the amount of gas supplied.

Next, when the sub-float part floats on the water surface, the gas in the sub-float part continues to be released into the outside air in a larger amount than the amount of gas supplied from the buoyancy adjustment pipe, so the gas in the sub-float part decreases and the sub-float part collapses under its own weight, reducing its opening area. Therefore, the entire device is quickly lowered into the water by the weight of the device, and the above-described action is then repeated.

Then, when the gas in the gas supply runs out, the entire device automatically sinks due to its own weight and the weight of the equipment.

Therefore, the underwater floating device according to the present invention can automatically float in water and on the water surface without providing any special equipment, with a simple configuration and low manufacturing cost, and can float on the water surface for a long time. The operating time can be automatically controlled by the gas capacity in the gas supply.

〔Example〕

1 and 2 showing one embodiment of the present invention will be described below.

As shown in FIG. 1, the underwater floating device according to the present invention includes a main float part 1 having an opening 1a f at the bottom, and an opening 2a t- fixed to the upper part of the main float part 1 and opening 2a t-
a T-shaped buoyancy adjustment pipe 5 connecting the main float part 1 and the sub float part 2; - a gas supply section 4 that supplies into the h section 1;
It is comprised of a device 5, such as an audio device, held on the main float section 1.

The main float section 1 and the sub-float section 2 are made of cloth and rubber coated to close the eyes of the cloth so as to have elasticity.

Further, the main float section 1 receives the gas 7 from the gas supply section 4.
The sub-float section 2 is formed in a size that generates a buoyancy force smaller than the weight of the device 5 when it is filled with gas, and when the sub-float section 2 is floating in water, the amount of gas released into the water from the opening 2a is reduced. The amount of gas supplied from the buoyancy adjustment pipe 3 is also reduced due to water resistance, and when floating on the water surface, the amount of gas released into the outside air is reduced by the opening 2a. The opening 2a is formed so that the amount of gas is larger than the amount of gas, and the sub-float part 2
is a gas 7 floating in water and supplied from a floating pipe 5.
When the main float section 1 is full, the main float section 1 is formed to have a size that generates a buoyancy force greater than the weight of the device 50 in combination with the buoyancy force within the main float section 1.

Further, the position of the opening on the main float part 1 side of the flotation adjustment pipe 5 depends on the distance between the main float part 1 and the internal water surface 6, and the amount of gas in the main float part 1, that is, the magnitude of buoyancy, and the flow of the flotation adjustment pipe 3 through the main float part 1. The opening 2a of the sub-float part 2
Since the amount released varies, the position is adjusted in advance.

Since the underwater floating device according to the present invention is constructed as described above, its operation will be explained next with reference to FIGS. 2 and 3.

First, when the underwater floating device attached to the equipment 5t is released into the water, the gas supply section 4 reacts with water and supplies the gas 7t into the main float section 1.

After that, when the main float part 1 is filled with gas 7,
As shown in FIG. 2(a), a device 5 is installed inside the main float section 1.
The entire underwater floating device floats in the water by generating a buoyancy force that is smaller than the weight of the device.

Subsequently, the amount of gas 7 supplied from the gas supply section 4 is supplied into the sub-float section 2 through the buoyancy adjustment pipe 3;
When the sub-float part 2 is filled with an amount equal to the difference between the amount released into the water from the opening 2a and the sum of the buoyant force in the main float part 1 generates a buoyant force as large as 50 weight of the equipment, the underwater floating device The whole thing rises through the water.

Then, when the sub-float part 2 floats on the water surface.

Since a larger amount of gas is released into the outside air than the amount of gas supplied from the buoyancy adjustment pipe 5 through the opening 2a and the amount of gas inside the sub-float section 2 is reduced, the amount of gas inside the sub-float section 2 is reduced as shown in FIG. 2(b). is depressed by its own weight and reduces the area of the opening 2a, and at the same time, the weight of the device 5 quickly lowers the entire underwater floating device into the water, and the above-mentioned action is repeated thereafter.

In this way, after the underwater floating device floats in the water and on the water surface, when the gas in the gas supply section 4 runs out, the underwater floating device and the equipment 50 sink into the water due to their weight.

〔Effect of the invention〕

According to the present invention, it is possible to automatically float in and on the water surface with a simple configuration and low manufacturing cost without installing any special equipment, and the time spent floating on the water surface is shortened. and the operating time can be automatically adjusted depending on the gas capacity in the gas supply.
