Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for an underwater walking tunnel of an underwater aquarium or the like. 2. Description of the Related Art In an underwater amusement tunnel such as an underwater aquarium, watertight doors are provided at a plurality of locations in the tunnel in preparation for a flood accident in the tunnel, and the tunnel between the watertight doors is provided. There are multiple watertight compartments inside. [0003] In the conventional underwater walk tunnel of an underwater aquarium or the like, (1) when the underwater walk tunnel is damaged and a large amount of water enters, the water flows on the floor of the underwater walk tunnel. Evacuation may not be possible due to the large amount of inflow water. (2) A spectator who is in a section where a flood accident has occurred may not be able to evacuate before the watertight door is closed, due to escape. (3) In the event of a flood accident, the watertight door is closed by manual operation, so it is not possible to respond immediately to the flood accident. (4) Since the watertight door needs to be made of a material such as steel or concrete, there is a problem that the visibility to the outside is obstructed. The present invention has been made in view of the above-described problems, and its object is to solve the problem even if an inundation accident occurs.
An object of the present invention is to provide a safety device for an underwater walking tunnel that can secure time for evacuation of a spectator to a safe place and maintain the safety of the spectator. [0005] In order to achieve the above object, a safety device for an underwater walk tunnel according to the present invention comprises a mesh-like top plate corresponding to the floor surface of an underwater walk tunnel constructed on an underwater base. A tank is provided along the longitudinal direction of the underwater walking tunnel under the tank, and a plurality of tank partition walls provided in the tank and a plurality of guide plates provided in the underwater walking tunnel are used for the tank and the underwater walking. The inside of the tunnel is divided into a plurality of sections in the front-rear direction, and shutter take-up cases are provided on both front and rear sides of the upper end of each of the guide plates. When it flows in through the top plate, it receives the inflow water and descends in the tank of the section from directly below the mesh top plate to the bottom of the tank by the weight of the inflow water A watertight shutter closing seawater tank is supported by a wire extending from the shutter winding case so as to be able to move up and down,
When the seawater tank for closing the watertight shutter is lowered, the watertight shutter that is drawn out of the shutter winding case and closes the damaged section of the underwater walking tunnel is housed in the shutter winding case. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a safety device for an underwater walking tunnel according to the present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. 1 is an underwater walking tunnel of an underwater aquarium, and 1 is an underwater walking tunnel. 1 is provided on an underwater base 3 for underwater 2. Reference numeral 9 denotes a mesh-like top plate (top plate of a tank 12 to be described later) corresponding to the floor surface of the underwater walking tunnel 1, a tank 12 provided below the mesh-like top plate 9 along the longitudinal direction of the underwater walking tunnel 1, and 13 denotes a tank 12 A plurality of tank partition walls 8 provided therein are a plurality of guide plates provided in the underwater walk tunnel 1. The tank partition wall 13 and the guide plate 8 allow the inside of the tank 12 and the inside of the underwater walk tunnel 1 to be in the front-rear direction. Is divided into a plurality of sections. Reference numeral 4 denotes a shutter winding case provided on both front and rear sides of the upper end of each guide plate 8 (the ceiling of the underwater walking tunnel 1), 7 denotes a seawater tank for closing a watertight shutter, and 6 extends from each shutter winding case 4. The seawater tank 7 for closing the watertight shutter is located in each section of the tank 12 by the wire 6, and the section where the underwater walk tunnel 1 is damaged is damaged. When water invades, the intruding water flows into the watertight shutter closing seawater tank 7 via the mesh top plate 9 and the watertight shutter closing seawater tank 7 moves through the mesh top plate 9 in the tank 12 of the section according to the weight of the inflow water. Of the tank 12 to the bottom of the tank 12. Reference numeral 5 denotes a watertight shutter. The watertight shutter 5 is always accommodated in the shutter winding case 4, and when the seawater tank 7 for closing the watertight shutter is lowered, the watertight shutter 5 is moved from the shutter winding case 4. It is fed out along the guide plate 8, and the damaged section of the underwater walking tunnel 1 is closed by the watertight shutter 5. Reference numeral 10 denotes a door provided for each section of the underwater walk tunnel 1, and reference numeral 11 denotes an emergency escape tunnel provided outside the underwater walk tunnel 1 and the tank 12. Next, FIG.
The operation of the safety device of the underwater walking tunnel shown in FIG. 3 will be specifically described. When a section of the underwater walk tunnel 1 is damaged and water enters the underwater walk tunnel 1 from the damaged portion, the intruded water flows into the seawater tank 7 for closing the watertight shutter through the mesh-shaped top plate 9, and the audience can enjoy the water. Water does not accumulate on the existing floor (mesh top plate 9). When the inflow water starts to accumulate in the seawater tank 7 for closing the watertight shutter, the seawater tank 7 for closing the watertight shutter closes the tank 12 in the damaged section from directly below the mesh-shaped top plate 9 to the bottom of the tank 12 due to the weight of the inflow water. Seawater tank 7 for closing the watertight shutter that descends at the same time as descending
As a result, the watertight shutter 5 is extended from the shutter winding case 4 along the guide plate 8, and the damaged section of the underwater walking tunnel 1 is closed by the watertight shutter 5. A spectator on the floor (mesh top plate 9) evacuates to another section at the same time as the inflowing water starts to accumulate in the seawater tank 7 for closing the watertight shutter. When the watertight shutter 5 starts to descend and it is difficult to evacuate to another section, the watertight shutter 5 is evacuated from the door 10 provided for each section of the underwater walk tunnel 1 to the water surface via the emergency escape tunnel 11. The watertight shutter 5 is housed in the shutter winding case 4 provided on the ceiling of the underwater walking tunnel 1, so that the external view from inside the underwater walking tunnel 1 is not obstructed. As described above, the safety device of the underwater walking tunnel according to the present invention damages a section of the underwater walking tunnel,
If water enters the underwater walking tunnel from the damaged location,
Intrusion water flows into the seawater tank for closing the watertight shutter through the mesh top plate, and water does not accumulate on the floor (mesh top plate) where the audience is. When this influent starts to accumulate in the watertight shutter closing seawater tank, the weight of the inflow water causes the watertight shutter closing seawater tank to descend in the damaged section tank from directly below the mesh-shaped top plate to the tank inner bottom, and at the same time, to descend. The watertight shutter is fed out of the shutter winding case along the guide plate by the shutter closing seawater tank, and the damaged section of the underwater walking tunnel is closed by the watertight shutter. Then, the audience on the floor (mesh top plate) evacuates to another section at the same time as the inflowing water starts to accumulate in the seawater tank for closing the watertight shutter. In addition, if the watertight shutter starts to descend and it is difficult to evacuate to other sections, it will be evacuated to the water surface through the emergency escape tunnel from the door provided for each section of the tank, and a flood accident will occur. In addition, it is possible to secure time to evacuate the spectators to a safe place, and maintain the safety of the spectators.
