JPS63154411A - Amphibious submarine boat - Google Patents

Abstract

PURPOSE:To obtain a submarine boat which can easily approach or depart a pier or be hoisted by providing a pair of the right and left drive wheels capable of supporting a hull respectively at the front and rear of the lower end section of the pressure-proof structure hull and protruding Schneider propellers outwardly respectively on the outside of the wheels. CONSTITUTION:Horizontal shaft Schneider propellers 3 are arranged outwardly respectively on the front and rear and the right and left of the lower end of a submarine boat 1. Multiple variable-pitch rotary blades 3 having a blade- shaped cross section are protruded on the outside end face of a relatively large- diameter drive wheel 2 of each propeller 3. The rotary blades 3 can be changed simultaneously to the desired pitch via an interlocking mechanism, and the outer diameter of the wheel 2 is formed somewhat larger than the diameter of the circumscribed circle of the rotary blades 3. Thereby, the wheels 2 are driven for running on the land. On the other hand, the wheels 2 are driven for running on the water bottom or the propellers 3 are driven for running in the water.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an amphibious submersible for work or leisure purposes.

[Conventional technology]

For example, as shown in Japanese Patent Publication No. 58-2848, NFC rotating cylindrical floats with helical blades protruding from the outer periphery of the lower surface of the watertight vehicle body are installed side by side to enable driving on ice and in icy areas. Amphibious vehicles that can be used and
As shown in No. 8413, an amphibious vehicle has been announced that has a six-wheel drive watertight body and is equipped with an underwater thrust generator that pressurizes seawater sucked in from the front and sprays it rearward.

However, although each of these amphibious vehicles has its own features, none of them have the maneuverability to freely move back and forth, turn, and ascend and descend underwater like a fish.

[Problem that the invention seeks to solve]

To begin with, this type of vehicle and ship has the following problems, and it is most desirable that all of these problems be solved rationally.

(1) Submersibles operating underwater or for sightseeing have a problem in that it is difficult to take them to shore and retrieve them.

(2) Cabins for underwater work or sightseeing that are towed by wire have problems because depth control is difficult.

(3) A self-propelled cabin that navigates using rails laid on the seabed as a guide has a fixed course and does not have the freedom to choose a route.

(4) Four wheels for land travel and one propeller for underwater navigation Amphibious ships require a dedicated propeller for underwater navigation, which allows them to control direction and depth underwater. If changed, a rudder and ballast tank must be installed separately.

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide an amphibious submersible that is easy to berth and retrieve, and has ideal maneuverability such as being able to go up and down once, forward and backward, and turn freely. do.

[Means for solving problems]

To this end, the present invention provides a pair of left and right drive wheels that are respectively attached to the front and rear of the lower end of a pressure-resistant hull and capable of supporting the hull, and a Schneider professional drive wheel that is provided on the outer surface of each wheel to protrude outward. It is characterized by having a peller.

[For production]

With such a configuration, it is possible to obtain an amphibious submersible that has ideal maneuverability such as easy berthing and retrieval, single up/down movement, and freedom of speech.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view showing the land running and underwater running states, Fig. 2 is a partial horizontal sectional view taken along the line ■-■ in Fig. 1, and Fig. 3 is the first
FIG. 2 is a partial side view showing a depth control procedure for the submersible shown in the figure.

First, in FIGS. 1 and 2, reference numeral 1 denotes a submersible according to the present invention, and horizontal shaft Schneider propellers 3 are attached outwardly to the lower end of the submersible in each of the front, rear, left, and right directions.

Each Schneider propeller 3 has a relatively large diameter wheel 2
Five variable pitch swing blades 3 having an airfoil cross section are protruded at equal intervals on the outer end surface of the rotor, and the swing blades 3 can be changed to a desired pitch all at once via an interlocking mechanism. The outer diameter of the wheel 2 is made slightly larger than the diameter of the circumscribed circle of the swirler 3.

In such a structure, as shown in FIG. 1, on land the vehicle travels by driving the wheels 2. For this purpose, the wheel 2 is made to have a relatively large diameter.

Even in places without port facilities, it can advance underwater by driving the wheel 2, and after entering the water, it can travel under the sea by driving the wheel 2 as on land, or it can navigate underwater by using the thrust from the Schneider propeller 3 installed on the wheel 2. .

At that time, the Schneider propeller 3 can obtain thrust in any direction by changing the blade angle, so when changing the direction of travel of the hull 1, as shown in FIG. It is only necessary to reverse the direction of the thrust of one wheel and the direction of the thrust of the two wheels on the opposite side, and it is also possible to turn on the spot.In addition, when changing the depth of the hull 1, each wheel For example, as shown in Figure 3, α (the angle between the thrust direction of the stern side wheels and the hull center line) =
If β (the angle between the thrust direction of the bow side wheels and the hull center line) = 90° or β = 180'-α, then α
, β are positive, the hull l rises vertically upward without changing its attitude, and when α and β are negative, it descends vertically downward.

Also, if α=I, the depth can be changed diagonally upward or diagonally downward without changing the attitude, so by changing the direction of the thrust of each wheel 2, the hull l
can be moved in any direction and depth.

At that time, by adjusting the magnitude and direction of the thrust, it is possible to stand still underwater, allowing sightseeing or work to be carried out at any location.

[Effect of infu]

According to such a submersible, on the seabed by rotating the side wheel.

It is capable of self-blading, and can advance from land to the sea and land in places without port facilities, and can navigate underwater by rotating the wheels on the seabed or by thrust from the rotation of the wheels in the sea, as appropriate. You can work or sightsee in the following locations. In this case, the thrust from the Schneider propeller can replace part or all of the buoyancy from the ballast tank.

In short, according to the present invention, a pair of left and right drive wheels are respectively attached to the front and rear of the lower end of the pressure-resistant structure hull and can support the hull, and a sheather is provided that projects outward from the outer surface of each wheel. Equipped with an Idar propeller, it is easy to move up and down to and from the shore.

The present invention is industrially extremely useful because it provides an amphibious submersible with ideal maneuverability that allows it to move forward and backward and turn freely.
