Description

[Detailed description of the invention] underwater container The present invention relates to underwater containers.

Submersible containers of known type are enclosed areas that accommodate one or more users. Consists of ya. Users must enter the room through the hatch and remain underwater for a considerable period of time. Can be done. The container provides breathing air to the room and prevents the container from submerging or floating. Equipped with an air tank that supplies air to the flotation tank that allows the user to ascend . Additionally, the container includes a motor that allows the container to be maneuvered underwater.

Another type of submersible container is one that is positioned to create air bubbles at the same pressure as the surrounding water. It will be done. The diper can enter and exit the underwater container through the hatch.

These known containers are large, heavy and expensive to operate.

The inventor has devised an underwater container that alleviates the above-mentioned problems.

Viewed from the first aspect of the present invention, it consists of a main body part and a seat part, and the main body part is a capacitor. It is arranged so that it encloses a large amount of air above the seat part when the vessel is submerged in water, At least the user's head can be pushed out of the water into said volume of air, and This provides an underwater container that allows the user to breathe.

The body portion of the container may be relatively small.

Add ballast weights to the seat to help the container stay upright in the water. It is preferable to provide one.

Preferably, the bulk air is supplemented from a compressed air cylinder. cylinder is good Preferably, it is attached to the seat part so that the user sits astride the cylinder. It is good.

The container may also be propelled by a motor driven by compressed air. good. Alternatively, the container is preferably powered by a battery housed in the seat portion. It may be propelled by an electric motor supplied with Instead , the container is not equipped with a motor (or the motor may be shut off) and the user ``walk'' along the ocean floor or riverbed while straddling the sheet. You can also do it.

It will be appreciated that containers consume significant amounts of compressed air during use.

Accordingly, in view of the second aspect of the invention, supplying breathing air to the user of the container A submersible vessel consisting of a pneumatic motor with an exhaust port arranged to be done.

In this case, the pneumatic motor should be installed with an oil stop to prevent fumes from being sent to the exhaust port. It is preferable that it be of type.

Bicycle that directs air from the compressed air tank to the exhaust port when the motor is not running. Preferably, a path is provided.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view of an underwater container according to the invention.

FIG. 2 is a front view of the underwater container of FIG. 1.

FIG. 3 is a cross-sectional view taken along line III in FIG.

Referring to the drawings, an underwater vehicle comprising a body portion 10 mounted on a seat portion 12 container is shown. The body portion 10 has a sealed dome shape with an opening at the bottom. It consists of several compartments. The compartment is sealed against the casing 15 by a seal 13 It includes a window 11. When the container enters the water, air bubbles are trapped inside the compartment. , the user sitting on the seat part 12 can lower his head and upper body to breathe the trapped air. into the compartment. The container is connected to a compressed air motor 41 that drives a propeller 43. More power is provided. The exhaust air from the motor is used to replenish the air inside the compartment. This reduces the overall amount of air consumed in the container. compressed air Air is supplied from a tank 31 mounted inside the seat portion 12. Seat part A closure 38 is provided at the minute 12 to allow the tank 31 to be removed. , to allow access to the ballast weight 37 installed under the tank 31. Ru. The ballast weight 37 measures the amount of water displaced by the trapped air. is almost the same. The ballast weight 37 is removable, and the container is underwater. so that it can be easily transported when it is taken out.

There is a nozzle 42 behind the propeller 43 that can indicate the direction so that the vessel can be steered. It will be installed. For example, a control device 33 for controlling the speed and direction of the motor is placed in front of the user. It is attached to a surface and supplies compressed air along multiple vibrators 39 to each motor and actuator. Instruct the device to supply.

A buoyancy bag 34 is housed inside the main body 10 and can be inflated to float the container. Wear.

Air is supplied to the compartment through a port 45 and an outlet 46 is provided to chase away excess air. to maintain a constant amount of air. rapidly release trapped air A control device may be provided to enable this. In addition, there is a control device to ascend at a controlled speed from depth for decompression purposes. It may be provided. surfacing when air supply is low, being recalled and surfacing, or an automatic control device may be provided to stop diving below a predetermined depth. .

The container may be equipped with grab handles, lights, cameras, etc., and lifting points. is preferably formed at the top of the body portion.

As mentioned above, when the motor is switched off, the user remains astride the seat. You can also ``walk'' along the ocean floor or river bed. Another embodiment of the container is completely It does not have to be equipped with a tar.
