Abstract

PURPOSE:To make it possible to allow viewing people to safely retire even through seawater flows into the viewing room due to an accident by providing an independent structure having a buoyancy with respect to water or seawater and being vertically movable, in the underwater viewing room. CONSTITUTION:If an underwater viewing window 2 is broken due to an accident so that a large amount of seawater flows into an underwater viewing room 1, a floating floor structure 3a produces a buoyancy and floats up as the water lever ascends. Meanwhile a hull 7 submerges until the volume 9a of the underwater viewing room 1 below the draft line 8b upon the accident becomes equal to the volume 9b of the hull 7 between the daft line 8b upon the accident and the normal draft line 8a before seawater flows into the viewing room.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an underwater observation room applied to an underwater observation boat, an underwater observation tower, or the like. [Prior Art] For example, as shown in Fig. 12, an underwater viewing window 2 is provided on the side wall of an underwater viewing room 1 below the sea surface for the purpose of allowing the general public to easily observe fish, shellfish, coral, etc. in seawater. Undersea observation towers and underwater viewing boats with underwater viewing windows installed on part of the bottom of the cruise ships are being built or planned. [Problems to be solved by the invention] However, in order to enjoy the underwater scenery, it is necessary to provide an underwater observation window as large as possible, and this is why the underwater observation tower currently being constructed has not been adopted. The maximum size of the underwater viewing window is approximately 700mm x 400 questions. The probability of breakage increases as the size of these large viewing windows increases, so safety measures such as double-paned windows are being taken. However, unlike steel plates and the like, glass is a brittle material, so if it is damaged, a large amount of seawater will enter, creating a safety problem. Furthermore, there is a risk of collision with underwater viewing boats, so when installing an underwater viewing room in a deep underwater location, simply increasing the safety factor for the strength of the glass is not enough to prevent elderly people from colliding in the event of an accident. There is a problem that unspecified large numbers of people, such as children, cannot escape safely. The present invention was proposed in view of these circumstances, and
To provide an underwater viewing room with which visitors can safely evacuate even if seawater flows into the underwater viewing room due to an accident or the like. [Means for Solving the Problems] Therefore, the present invention provides an underwater viewing room that includes an independent structure that has buoyancy with respect to water or seawater and is movable up and down within the room. It is a feature. [Operation] With the above-mentioned configuration, if the glass of the underwater viewing window is broken for some reason and a large amount of seawater flows into the underwater viewing room, the independent structure inside the underwater viewing room will gradually float up. [Example] An example of the present invention will be described with reference to the drawings. 1 to 5 show an underwater observation boat equipped with a floating floor structure as an independent structure inside an underwater observation room as a first embodiment of the present invention, and FIG. 1 is a side view thereof. Figure 2 is a vertical cross-sectional view of Figure 1, Figure 3 is a cross-sectional view of Figure 2, Figure 4 is a vertical cross-sectional view showing the floating floor structure in a floating state, and Figure 5 is a cross-sectional view of Figure 4. It is a diagram. 6 and 7 show an underwater observation tower having a floating floor structure as an independent structure inside an underwater viewing room as a second embodiment of the present invention. FIG. 6 is a longitudinal sectional view thereof, and FIG. 7 is a longitudinal sectional view showing the floating floor structure in a floating state. Figures 8 to 11 show an underwater viewing boat as a third embodiment of the present invention, which is equipped with an internal viewing room with an independent structure inside the underwater viewing room. The figure is a plan view, Figure 10 is a front view, and Figure 1 is a front view.
Figure 1 is a central sectional view. In the first embodiment shown in FIGS. 1 to 5, an underwater viewing room 1 that projects downward is provided at the center of the bottom of the underwater viewing boat, and underwater viewing windows 2 are provided on the sides, front and rear of the underwater viewing room. is provided. On the floor of the underwater viewing room 1, a floating floor structure 3a is provided which is movable up and down as an independent structure of a lightweight structure as a floating body, separately from the structure of base 1.
and between the lateral and anterior and posterior walls of base 1. Guide rollers 4 are provided so that the floating floor structure 3a can move up and down smoothly in response to buoyancy. In addition, the upper part of the underwater viewing room 1 has a space 5 so as not to hinder the rise of the floor structure.
The surrounding wall 6 is a water bulkhead to prevent seawater from entering the hull 7. In such a structure, if the underwater viewing window 2 is broken due to some accident and a large amount of seawater flows into the underwater viewing room 1, the floating floor structure 3a will generate buoyancy. It rises to the surface as the water surface rises. On the other hand, the hull 7 is
Volume 9a of underwater viewing room 1 below water line 8b at the time of accident
When the accident water line 8b and the volume 9b of the hull 7 with the normal water line 8a open before the inflow of seawater become equal, the vessel is submerged and balanced as shown in FIGS. 4 and 5. Note that the embodiments in Figures 1 to 5 show the case where the underwater viewing window 2 is provided on the side, front and rear of the underwater viewing room 1, but 1, for example, the underwater viewing room may be protruded from the bottom of the ship. If the underwater viewing window 2 is installed on the floor of the underwater viewing room 1 due to reasons such as impossibility, a notch is also provided in the floating floor structure 3a corresponding to the underwater viewing window 2, and a wire mesh is installed in this notch. Alternatively, a glass or the like may be provided. 6 and 7 show a case where the present invention is applied to an underwater observation tower as a second embodiment. In the above figure, the parts having the same numbers as those in the first embodiment shown in Figs. 1 to 5 are equivalent structural members, and therefore the description thereof will be omitted. Note that 3b is a floating floor structure as an independent structure, and 8c
is the water line. 10 is a spiral staircase. In the configuration shown in FIG. 6, when the underwater viewing window 2 is destroyed due to some accident and a large amount of seawater flows into the underwater viewing room 1, the floating floor structure 3b generates buoyancy and floats up together with the spiral staircase 10 as the water level rises. Then, the state shown in FIG. 7 is reached. Note that in the second embodiment shown in FIGS. 6 and 7, the guide rollers 4 are provided around the floating floor structure 3b, but instead of this, the spiral staircase 10 is made hollow, and a guide column is installed in the hollow. may be provided. Furthermore, in the first and second embodiments, when the floating floor structures 3a and 3b rise to the surface in the event of an accident, seawater flows into the lower parts of the floating floor structures 3a and 3b and the underwater viewing room 1.
However, if the gap is not sufficient, the floating floor structures 3a and 3b may be provided with seawater circulation holes with appropriate covers such as gratings. Furthermore, in order to prevent nine people from getting caught in the gap between the floating floor structures 3a, 3b and the side wall of the underwater viewing room 1 when the floating floor structures 3a, 3b surface, it is further possible to provide a fence around the upper part of the floating floor structures 3a, 3b. Safety is increased. Also, the fence is a floating floor structure 3a. The upper part of the fence may be tilted or curved inward in consideration of the oscillation when 3b floats. If there is not enough space 5 for the floating floor structures 3a and 3b to float, a buffer member is installed between the floating floor structures 3a and 3b and the ceiling to prevent people on the floating floor structures 3a and 3b from colliding with the ceiling. established. For example, the floating floor structures 3a and 3b may stop several tens of centimeters below the water surface. Next, we will introduce the third example with even higher safety.
As shown in the figure. In the drawings, parts with the same numbers as those in the first embodiment shown in Figs. 1 to 5 are uniformly grooved members, and therefore the description thereof will be omitted. In the figure, 30 is an internal viewing room as an independent structure with windows around it, 11 is a water viewing window, 12 is a rear exit, and 13 is a front exit. 14 is a propulsion device, 15 is an entrance, and 16 is a lifting device. As shown in FIG. 4, the internal viewing room 3C is located above by a lifting device 16, and the general public enters through the entrance 15. When viewing underwater, the internal viewing room 3C is lowered using the lifting device 16. In this way, the entire interior viewing room 30 can be moved up and down, allowing visitors to see the scenery above and below the water surface.Furthermore, since diving is simulated, there is no danger to the general public. You can experience the same sensation as diving. The lifting device 16 and the internal viewing room 3C are designed to be able to be fitted in and out, or to be separated from the driving device (not shown) in the lifting device 16, so that seawater does not enter into the underwater viewing room 1 in the event of an accident. Time, internal viewing room 3
C floats up due to its buoyancy. Furthermore, the climbing 15. Front exit 1
3 and a rear outlet 12 may be provided. [Effects of the Invention] As described above, according to the underwater viewing room of the present invention, if the glass of the viewing window is broken for some reason and a large amount of seawater flows into the underwater viewing room. The independent structure inside the underwater viewing room floats, which has the effect of greatly improving the safety of viewers. 4 [BRIEF DESCRIPTION OF THE DRAWINGS] Figures 1 to 5 show a sea monster as a first embodiment of the present invention, with Figure 1 being a side view thereof, Figure 2 being a longitudinal cross-sectional view of Figure 1, and Figure 3 being a vertical sectional view of Figure 1. is a cross-sectional view of FIG. 2, and FIG. 4 is a vertical cross-sectional view showing the floating floor structure in a floating state.
