Abstract

PURPOSE:To make even general sightseers possible to take pleasure in underwater sightseeing as the same degree as a scuba diver by constituting an underwater pleasure boat having an self-propelling type underwater sightseeing dome. CONSTITUTION:Floating bodies 1, 2 are provided with propellers 3 and 4, and an interval between these floating bodies is connected to each other by a promenade deck 6. An underwater sightseeing dome 9 having ventilating towers 12, 13 is attached to this promenade deck 6 free of vertical motion. In this underwater sightseeing dome 9, there are provided with a water ballast tank 14 and a pump 16 for pumping and draining. Water is poured into the underwater sightseeing dome and thereby this dome is constituted, thus sightseers are able to enjoy the underwater sightseeing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a submersible underwater excursion boat for observing relatively shallow water and the seabed.

[Conventional technology]

As a conventional invention, 1, for example, Japanese Patent Application Laid-Open No. 60-240598
As introduced in the publication, a glass port is known in which a transparent window is provided on the side of the ship near the bottom of the ship or on the bottom of the ship to view underwater near the water surface.

(Problem to be solved by the invention) The above-mentioned observation window is used for underwater viewing near the water surface.

This is due to the relatively narrow field of view, such as partial observation of the ocean floor.

The situation is such that it is not possible to enjoy underwater excursions. Therefore, the present invention
We demonstrate the technology of a submersible underwater excursion boat that allows ordinary tourists to enjoy underwater excursions to the same degree as skinny bar divers.

[Means for solving problems]

The present invention is arranged symmetrically at predetermined intervals.

Two floating bodies equipped with propulsion devices, a catamaran in which the floating bodies are connected together on the water surface by a promenade deck and arms, and an underwater observation dome is movably supported on the promenade deck in the upper and lower treasure chambers. multiple sets of support frames.

a ventilation tower that is fitted into the plurality of sets of support frames and is movable in the vertical direction; an underwater observation dome connected to the ventilation tower;
The underwater observation dome is located on a submersible underwater pleasure boat equipped with a water ballast tank and a pump for injecting and draining water ballast.

[For production]

An observation dome made of reinforced glass, metal, etc., which is supported by support frames on the promenade deck placed at predetermined intervals and can move vertically, is floated to a predetermined level of water, and sightseeing passengers are boarded to take it to the underwater excursion area. After that, water ballast was poured into the water ballast tank located at the bottom of the observation dome floor, and with the ventilation tower supported by the support frame on the promenade deck, the observation dome was lowered to a predetermined water depth, and each unit was submerged. It propels itself using a propeller installed in its body and offers underwater excursions.

After the underwater excursion is over, the water ballast in the water ballast tank under the floor of the observation dome is drained by a pump, the observation dome is floated to a predetermined level of water, and the excursion passengers are allowed to disembark.

〔Example〕

An embodiment of the present invention will be described in the first embodiment. This will be explained with reference to FIGS. 2 and 3.

Two floating bodies 1 and 2 are arranged symmetrically with a predetermined corner space apart and are equipped with propellers 3.4, and the above-mentioned floating body is connected between the floating bodies 1.2 on the water surface 5 by a walking deck 6 and arms 7 and 8. 1 and 2 are integrally connected to a catamaran 100.

A plurality of sets of support frames 10.11 movably support the underwater observation dome 9 in the vertical direction on the promenade deck 6, and a ventilation tower 12.13 that is fitted into the plurality of sets of support frames 10.11 and movable in the vertical direction. The underwater observation dome 9 is connected to the ventilation tower 12.13, and the underwater observation dome 9 is equipped with a water ballast tank 14.15 and a pump 16 for injecting and discharging the water ballast.

First, underwater sightseeing passengers are boarded through the entrance 17 shown in FIG. 3 at the underwater observation dome 9 which is in state A floating above the water surface 5 in FIG. 1, and the entrance 17 is closed to create a watertight state. The water ballast tank 14.1 is self-propelled by the propeller 3.4 to a predetermined sea area and placed on the floor of the underwater observation dome 9.
5 using the pump 16 to sink the underwater observation dome 9 to position B in a predetermined underwater part. At this time, the ventilation towers 12 and 13 connected to the underwater observation dome 9 are connected to the promenade deck 6.
It is held by fitting a support frame 10.11 provided therein.

After the above underwater excursion is completed, the underwater observation dome 9 is floated by the reverse operation to the above, and the underwater excursion passengers are allowed to disembark.

The underwater observation dome 9 is made of tempered glass, metal, etc., and is designed to widen the field of view as much as possible, and the ventilation towers 12 and 13 are equipped with spiral emergency stairs and ventilation fans. Consider safety.

In this embodiment, the entrance 17 to the underwater observation dome 9 is provided in the side wall of the underwater observation dome 9.

There is no problem in using the ventilation towers 12 and 13 as entrances and exits; in this case, a deck extending from the cockpit 18 will be provided and passengers will board and disembark from this position.

〔Effect of the invention〕

The twin-hulled underwater excursion boat of the present invention has very good safety during diving, and since the propulsion device is placed in each single hull, there is no noise or vibration (and comfortable underwater excursion is possible).
