Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a ground monitoring device for a nuclear silter, which is used by evacuees inside the nuclear silter to monitor conditions on the ground.

"Conventional technology" In conventional nuclear siertas, there is no device that allows evacuees to monitor or observe the situation on the ground while staying in the evacuation area, and in order for evacuees to know the situation on the ground, they must do it themselves. It is necessary to open the hatch door that closes exits such as escape exits leading to the ground and observe the ground. In this case, evacuees cannot know what is happening on the ground until they open the hatch, and there is a risk that they will be in danger as soon as they open the hatch.

``Problem that the idea aims to solve'' This idea was devised in view of the above circumstances. The goal is to be able to observe the situation and confirm that evacuees are safe before evacuating to the ground.

``Means for Solving the Problems'' In order to solve the above-mentioned problems, this invention has an entrance room that is separated from the evacuation area, communicates with the entrance room, and opens upward at the ground level. an entrance/exit, a hatch door swingably supported on one side of the entrance/exit so as to be able to open/close the entrance/exit, a door opening/closing drive device disposed within the entrance/exit and driving the hatch door, and an inner side of the hatch door. A technical measure is taken to provide a side-supported imaging device and an imaging device located within the evacuation area and reproducing the ground image obtained by the imaging device.

"Example" This invention will be described in detail below with reference to the drawings.

FIG. 2 is a vertical sectional view of a nuclear shelter according to an embodiment of the invention, and FIG. 3 is a cross-sectional plan view taken along the line of FIG. 2. The interior of this nuclear shelter 1 is divided into five chambers by partition walls 2-5. That is, a machine room 6, an entrance room 7, a sanitary equipment room 8, a living room 9, and an emergency escape room 10. The machine room 6 and the entrance/exit room 7 are always in communication with each other through a through-hole, and an entrance 11 provided on one side of the entrance/exit room 7 and an escape port 12 opened upward on the ground above the entrance/exit room 7 are connected to each other through a through-hole. is communicated with. The entrance 11 above is an airtight door 1
3, and the escape port 12 is opened and closed by a hatch door 14 pivotally supported on one side thereof. A through-hole 15 that communicates the entrance/exit room 7 and the sanitary equipment room 8 is opened and closed by an airtight door 16, and a through-hole 17 that connects the sanitary equipment room 7 and the living room 9 is opened and closed by an ordinary door 18. The through hole 19 that communicates the living room 9 and the emergency escape room 10 is an airtight door 20.
It is opened and closed by The emergency escape room 10 communicates with the ground through an emergency escape exit 21 that opens upwards above the ground, and the emergency escape exit 21 has a hatch door 22 pivotally supported on one side thereof. It is opened and closed by

In this nuclear shelter 1, an evacuation living area 23 is constructed of the ground floor, a sanitary equipment room 8 and a living room 9 which are double closed by the airtight doors 13, 16, 20 or hatch doors 14, 22.

Inside the emergency escape exit 21 is the hatch door 22.
A door opening/closing drive device 24 made of a hydraulic cylinder for forcibly driving the door opening/closing is provided. Further, a television camera (imaging device) 26 is supported on the inner surface of the hatch door 22 via a support frame 25. As shown in FIG. 1, this camera 26 is configured so that when the hatch door 22 is opened at a predetermined angle by the door opening/closing drive device 24, the incident optical axis is horizontal and the camera 26 is rotated about the vertical axis. 27 is a rotation drive device for rotating the camera 26. Furthermore, a television receiver 28 as a video device for displaying images taken by the camera 26 is provided in the living room 9. It should be noted that control means and control tools (not shown) for controlling the door opening/closing drive device 24, the camera 26, and the rotation drive device 27 are incorporated into the television receiver 28.

Prior to escaping to the ground, the evacuee opens the hatch door 22 of the emergency escape exit 21 using the door opening/closing drive device 24 by operating the control tool attached to the television receiver 28 in the living room 9. It is opened to a predetermined angle, the camera 26 is spanned horizontally by the rotary drive device 27, and the camera 26 photographs the scene on the ground except for the area shaded by the hatch door 22, and the image is projected on the television receiver 28. You can explore the situation on the ground. For example, if there are any dangerous animals, check the hatch doors 14, 22.
After confirming the safety of the ground, such as whether there are any wood, steel frames, etc., on the ground, escape to the ground through the escape exit 12 or the emergency escape exit 21. When escaping from the emergency escape exit 21, the hatch door 22 is opened further by a door opening/closing drive device 24 to prevent the support frame 25, camera 26 and rotary drive device 27 from getting in the way of escape.

Of course, this invention is not limited to the above-mentioned embodiment. For example, the camera 26 may be supported by the support frame 25 so as to be able to swing vertically, and the camera may be controlled by the control device described above to swing the camera vertically. A driving swing drive may also be provided. In this case, not only can the optical axis of the camera 26 be spanned horizontally or vertically, but also the incident optical axis of the camera can be freely directed in any direction by combining the horizontal span and the vertical span. You will be able to do that.

``Effects'' As explained above, this invention consists of an imaging device that is placed in an escape room separated from the evacuation area and can take pictures of the scene on the ground, and an imaging device that is placed in the evacuation area of the nuclear sierta. Since the evacuees are equipped with a video device that displays images obtained by By escaping to the ground after the accident, you have the advantage of not encountering unpredictable danger. or,
Since the imaging device is attached to the inner surface of the hatch door that closes the escape exit, there is no risk of damage due to high temperatures or blast waves during the explosion, and it also has advantages such as being able to operate reliably when necessary.
