Abstract

PURPOSE:To supply fresh air all the time, by situating an air suction port of a compressor on a floating body receiving a wind to its sale, in the more windward than an exhast port of an engine, in the case of a driving device which guides the air from top of a water surface to a regulator of a diver. CONSTITUTION:When a compressor 5 is driven by an engine 4 and a diver inhales air from a regulator 54 in the water, air in the atmosphere is inhaled out of an air suction port 51, supplying air to the regulator 54 through a charging hose 53. At this time, if a sale 60 receives a wind, each floating wheel 1 unitized with a mast, where the sale 60 is attached, and a mount block 2 rotate within a plane surface, whereby the sale 60 is made so as to be situated in the leeward, and the engine 4 is situated in the leeward as well, thus the compressor 5 is made so as to be situated in the windward in consequence. Therefore, the air suction port of the compressor 5 is directed to the windward, and an exhaust pipe 42 of the engine faces to the leeward, exhausting the exhaust gas to the leeward in consequence. Accordingly, this method comes to supply fresh air to the regulator 54 all the time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to an improvement in a diving device that guides air from above the water surface through an air supply hose to a regulator of a diver.

(Prior art) Conventionally, in order to guide air through a hose to the regulator of a submerged dialer, an engine and a compressor driven by the engine were placed on a floating body floating on the water surface.
Hidden diving equipment is known. Since this floating body is only floating on the instep, its direction is not constant, and therefore the positional relationship between the compressor's air suction port and the engine exhaust port is also not fixed, and depending on the wind direction, the compressor's air There is also a risk that the suction port will be on the leeward side of the engine exhaust port and inhale engine exhaust gas.

(Purpose of the Invention) This invention was made to eliminate such conventional drawbacks, and has a simple configuration that allows the air suction port of the compressor to always be upwind of the exhaust port of the engine regardless of the wind direction. Therefore, the present invention provides a diving device that is free from the risk of inhaling engine exhaust gas.

(Structure of the Invention) In the present invention, an engine and a compressor driven by the engine are placed in parallel on a floating body having a mounting table formed on the upper surface, and outside air is supplied from the compressor to a regulator underwater. In a diving device in which air is passed through a hose, a mast having a sail is installed on the floating body near the end on the side where the engine is mounted.

It is preferable that the exhaust pipe of the engine faces the side opposite to the side where the compressor is installed, and the air suction port of the compressor faces the side opposite to the side where the engine is installed.

In the above configuration, as the sail catches the wind, the end of the floating body on the mast installation side is positioned downwind, so the air suction port of the compressor is always located upwind of the engine exhaust port. .

(Example) In FIG. 1, a floating body is formed by attaching a mounting base 2 made of a plate material to the inside of an annular floating ring 1.
A floating body having a structure is floated on the water surface 3. An engine 4 and a compressor 5 driven by the engine 4 are placed on the top surface of the mounting table 2 in parallel arrangement. An intake pipe 41 and an exhaust pipe 42 are installed above the engine 4 facing in opposite directions, and an air intake port 51 is installed above the compressor 5 facing away from the engine 4.

An air supply hose 53 is connected to the upper side of the compressor 5 through an air discharge port 52, and this air supply hose 53 extends underwater, and a regulator 54 is attached to its tip.

Further, a mast 6 is installed on the mounting table 2 and has a sail (spanker) 60 attached near the end on the side where the engine 4 is placed, and is held vertically by a support cable 61.

The floating ring 1 may be constructed of an air bag made of rubber or plastic sheet, or may be constructed of an annular foam material. Roughly speaking, the entire floating body may be composed of a flat plate-shaped buoyancy material. Further, the sail 60 may be made of cloth, a plastic plate, or other plate material. Furthermore, the sail area may be configured to be changeable so as to correspond to the strength of the wind.

In the above configuration, the engine 4 drives the compressor 5, and the dialer (not shown) operates the regulator 5 underwater.
4, the air in the atmosphere is sucked from the air suction port 51, and is passed through the air supply hose 53 to the regulator 5.
Supply air to 4.

At this time, if there is no wind, the float 1 faces in any direction, but since the air suction port 51 faces in the opposite direction to the engine exhaust pipe 42, it does not suck in exhaust gas from the engine.

Also, when wind occurs, as shown in Figure 2, the sail 60
In order to catch the wind, the mast 6 to which the sail 60 is attached, the floating ring 1 and the mounting platform 2 rotate in a horizontal plane so that the sail 60 is located on the leeward side, and the sail 60 is placed on the lee side. The installed engine 4 is located on the leeward side, and the compressor 5 is located on the windward side. Therefore, regardless of the direction of the wind, the air suction port 51 of the compressor 5 faces upwind, and the exhaust pipe 42 of the engine faces downwind to discharge exhaust gas downwind. Without inhaling exhaust gas from one engine,
This ensures that fresh air is always supplied to the regulator 54.

(Effects of the Invention) As explained above, according to this invention, when the sail receives wind, the end of the floating body on the mast installation side is positioned on the leeward side, so that the air suction port of the compressor is always connected to the engine. Since the exhaust port is located upwind from the exhaust port of the engine, it is possible to reliably prevent engine exhaust gas from being sucked in regardless of the wind direction.
