DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater vehicle for use in seabed surveys and the like.

[0002]

2. Description of the Related Art In a conventional underwater vehicle for seabed survey, a communication portion for balancing the water pressure applied to the inside and outside of the outer plate is provided so that the thickness of an outer plate mounted on the outer side of the inner frame can be reduced. A non-breakdown voltage structure is provided. By providing a buoyancy tank section inside, the function as a floating body is maintained.

[0003]

By the way, in the above-mentioned conventional underwater vehicle, there is a possibility that when it is suspended from the mother ship and floating on the sea surface, it receives an impact load due to waves. In other words, seawater attached to the outer plate of the underwater vehicle gives a large inertial force, so it is only necessary to increase the thickness of the outer plate and the inner frame due to the waves, but this causes a problem that the weight increases significantly. is there. The present invention seeks to solve the above-described problems, and an object of the present invention is to provide an underwater vehicle capable of sufficiently avoiding damage due to waves while employing a non-pressure-resistant structure. I do.

[0004]

In order to solve the above-mentioned problems, an underwater vehicle according to the present invention is covered with a non-pressure-resistant outer plate having a communicating portion with external water and has a buoyancy tank inside. in the underwater vehicle equipped, in the same underwater vehicles is sea level
Pass the above-mentioned communication section inside the underwater vehicle while floating.
Water that is constantly entering the underwater vehicle
Discharge from the other side of the underwater vehicle when waves arrive
In order to reduce the inertial force of the underwater vehicle,
An opening with a hinged lid that opens outward is provided on each of the outer plates of the non-pressure-resistant structure on both sides of the underwater vehicle . In the above-mentioned underwater vehicle, when a wave is received while suspended from the mother ship and floating on the sea surface, the opening with the hinged lid provided on the outer plate is shifted to the open state, and the The drainage action is performed to reduce the inertial force of the underwater vehicle, thereby reducing the wave impact received by the underwater vehicle.

If the hinge of the hinged lid opening is provided with a spring for urging the lid to return to the closed state, the lid that is opened when a wave arrives automatically closes after passing the wave. , Safety will be improved.

Further, if the lid of the hinged lid opening is configured to open outward, the operation when the water inside the underwater vehicle is rippled and discharged to the outside is controlled by the lid. The above-mentioned operation is more appropriately performed when the wave comes from a dangerous side, particularly when the hinged lid opening is provided on each of the side ports, particularly when the opening is provided on both sides. Become like

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of an underwater vehicle according to an embodiment of the present invention, FIG. 2 is a plan view thereof, FIG.
FIG. 4 is an explanatory view showing a state where the mother ship is connected to the mother ship via a cable.

As shown in FIGS. 1, 2, 3 and 4,
An underwater vehicle 5 for seafloor survey covered with a non-pressure-resistant outer plate 4 having a communication portion with outside water is connected to a mother ship 6 by the cable 3 so that the cable 3 is connected to an upper portion thereof. Have been. The underwater vehicle 5 is floating on the water
Also communicates with the external water provided on the outer plate 4 of the non-pressure resistant structure.
The outside water always enters inside the underwater vehicle 5 through the section
It is crowded. (Refer to the internal water surface indicated by the broken line in FIG. 3)

The underwater vehicle 5 is provided with a buoyancy tank (not shown) therein and a vertical fin 2 at the rear end.
Further, a pair of front and rear hinged lid openings 1 are provided on the outer plates 4 on both sides, respectively. A hinge (not shown) is mounted on the hinge at each hinged lid opening to encourage automatic restoration of the lid from the outward open state to the closed state. Also, as shown in FIG. 3, inside the underwater vehicle 5
Various on-board devices 7 for propulsion and observation are housed.

[0010] In the above-mentioned underwater vehicle 5 , it is hung from the mother ship 6 and floats on the sea surface, as shown in FIG.
When a wave is received from the side , the opening of the opening 1 with the hinged lid provided on the starboard side outer plate 4 of the underwater vehicle 5 shifts to the open state, and drainage from the inside through the opening 1 is performed. Is performed, the inertial force of the underwater vehicle 5 is reduced, and thereby the wave impact received by the underwater vehicle 5 is reduced.

Since the hinge of the hinged opening 1 is loaded with a spring for urging the lid to return to the closed state, the lid that is opened when a wave arrives is automatically closed after the wave passes. And safety will be improved.

Further, since the lid of the opening 1 with the hinged lid is configured to open outward, as shown in FIG. 3, the water inside the underwater vehicle 5 undulates to the outside. The operation at the time of discharging will be performed accurately by the automatic opening of the lid, particularly when the hinged lid opening is provided on each side, when a dangerous wave comes from the side. The above operation is performed more appropriately.

[0013]

As described in detail above, according to the underwater vehicle of the present invention, the following effects can be obtained. (1) underwater vehicle is, when receiving the waves from one side in a state that floats on the sea surface is lowered suspended from the mother ship, on its other side
The opening of the opening with the hinged lid provided on the outer plate in the open state allows drainage from inside to be performed accurately, and the inertial force of the underwater vehicle decreases, thereby Wave shocks received by the mid-ship will be reduced. (2) If the hinge of the hinged opening with a lid is loaded with a spring that encourages the lid to return to the closed state, the lid that opens when a wave arrives will automatically close after the passage of the wave, and safety will be ensured. Sexuality will be enhanced. (3) Since the hinged lid of the lid opening is configured to open outward, the operation of when the internal water underwater vehicle is discharged to the outside surging of the lid automatically Opening can be performed more accurately, and in particular, by providing the hinged lid openings on both sides, the above-described operation can be performed more appropriately when a wave comes from a dangerous side. Become.
