Next, the operation will be described. When a large amount of rainwater or the like accumulates on the ground floor 10 due to concentrated torrential rain or the like, the water tends to flow into the basement 1 via the underground waterway 7. The water that has flowed into the basement 1 is accumulated in the drainage tank 4 and is drained to the sewer by the drainage pump 3. A flow detector 6 is provided on the way. The amount of inundation per hour when a large amount of rainwater accumulated on the ground floor 10 tries to flow into the basement 1 via the underground passage 7 due to the torrential rain, etc., is detected by the flow rate detection device 6, and the data is used as a flow control unit 5
Is output to The flow control unit 5 compares the flow detection device 13 with the drainage capacity 14 input in advance for each site, and outputs a partition plate control signal 15 when it is determined that water is flooded beyond the drainage capacity 14. Then, the partition plate driving device 9 is driven to raise the partition plate 8 in the direction of arrow X. Thereby, infiltration of water from the underground passage 7 into the basement 1 can be suppressed, and danger for the person 2 in the basement 1 can be prevented.

Embodiment 2 FIG. FIG. 3 is a configuration diagram of a waterlogging prevention device according to Embodiment 2 of the present invention. The inundation prevention device according to the second embodiment of the present invention is a case where the underground passage 7 is a path for a car to enter the basement 1.
Reference numeral 6 denotes a vehicle detection unit that detects the passage of a vehicle. When a large amount of rainwater or the like flows into the basement 1 via the underground passage 7, the flood prevention device according to the present invention drives the partition plate 8 to prevent the basement 1 from being flooded. However, if a vehicle enters or exits the basement 1 from the basement 1 to the ground floor 10 or from the ground floor 10 to the basement 1 while the partition plate 8 is being driven, there is a danger. Therefore, the vehicle detection means 16 such as a presence detector is provided with a certain distance from the partition plate storage location. When the vehicle detection means 16 detects the passage of the vehicle and outputs a vehicle detection signal to the flow rate control means 6, the output of the partition plate control signal is blocked, and the vehicle does not drive the partition plate and secures the partition plate storage location. Can pass through.

Things. FIG. 6 shows a flow detection device 6 and a flow control unit 5.
FIG. Although the configuration here is the same as that of FIG. 2 in the first embodiment, the flow control unit 5 compares the output 13 of the flow detection device 6 with the drainage capacity 14 indicating the drainage amount per hour of the drainage pump 3. This is a device that outputs a caution signal or a danger signal depending on the value of the output of the flow detection device.

In the fourth embodiment, when the detected value of the flow rate detecting means 6 reaches a predetermined first level with respect to the drainage capacity 14, the flow rate controlling means 5 pays attention to the alarm device 18. The warning device 18 outputs a signal and issues an announcement prompting the person 2 in the basement 1 to escape from the basement 1 at an early stage. In addition, if there is an in-house broadcast, it is effective to use the in-house broadcast to announce the warning to the entire in-house. Next, when the detected value of the flow rate detecting means 6 reaches a predetermined second level which is larger than the predetermined first level with respect to the drainage capacity value 14, the flow rate controlling means 5 switches to the partition plate controlling means 9 The danger signal is output to the alarm device 18 at the same time as the danger signal is output to the alarm device 18. Upon receiving the danger signal, the partition plate 8 is driven so that the person 2 in the basement 1 escapes urgently.
Give up to escape by car and announce to escape from stairs. Thereby, the person 2 in the basement 1 and the escape of the car can act in a timely manner.

Embodiment 5 FIG. 7 is a configuration diagram of a waterlogging prevention device according to Embodiment 5 of the present invention. In the figure,
Reference numeral 19 denotes an elevator installed in building equipment, and reference numeral 20 denotes an elevator control device for controlling the elevator. The inundation prevention device according to Embodiment 5 of the present invention is configured such that a person 2 who gets on the elevator 19 at the time of underground inundation goes to the basement 1 and
This is to prevent being unable to escape. FIG. 8 is a flowchart showing a control state of the elevator 19. FIG. 8 will be described below. It is determined whether the signal of the partition plate control signal 15 is a caution signal (step 1). When the signal of the partition plate control signal 15 is a caution signal, the button for going to the basement 1 of the elevator car 19 is invalidated to prevent the person 2 from going to the basement 1 by riding the elevator 19. Step A2 ". Subsequently, the alarm device 18 announces a message that the elevator 19 will soon be unavailable (step A3). Next, it is determined whether the signal of the partition plate control signal 15 is a danger signal (Step A4). If the signal of the partition plate control signal 15 is a danger signal, the elevator 19 is stopped on the ground floor, and "Step A5", so that the elevator 2 is submerged in the basement 1 and the person 2 riding the elevator 19 has no danger. To Thus, the danger can be prevented without the person 2 going to the basement 1 by the elevator 19 without knowing the inundation of the basement 1.

Embodiment 6 FIG. FIG. 9 is a configuration diagram of a waterlogging prevention device according to Embodiment 5 of the present invention. The inundation prevention device according to Embodiment 6 of the present invention is configured such that the worker 23 receives the warning signal of the partition plate control signal 15 and the danger signal of the partition plate control signal 15 to the elevator 19 via the alarm device 21 of the elevator 19. The management office 21 is notified. As a result, the customer manager may not know the abnormal situation,
The worker 23 of the management office 22 that has received the notification notifies the customer manager by telephone or the like to notify that the situation is dangerous.
Since an artificial instruction is added in addition to the automatic disaster prevention by the machine, the disaster can be more efficiently prevented. In addition, by reporting an abnormal situation at the site, the abnormal situation can be notified to a nearby customer, which leads to disaster prevention even for a customer who does not have the facility.

[0020]

As described above, according to the present invention, when the detected flow rate reaches the predetermined level of the drainage capacity value, the flow control means automatically controls the partition plate so as to close the inundation path. Therefore, it is possible to prevent flooding of the basement due to the amount of water that has entered exceeds the drainage capacity of the basement.

Further, when there is a vehicle passing through the projecting portion of the partition plate, the safety of the passing vehicle can be ensured by not operating the partition plate.

By outputting a lighting signal to the entry prohibition lamp simultaneously with the output of the partition plate control signal, it is possible to prevent the vehicle from entering the basement while the partition plate is being driven.

Further, the flow rate detection control means outputs a two-stage signal in accordance with the flow rate detection signal, and operates the partition plate for the first time when the danger signal which is the second signal is output. There is ample time from when the warning is issued by the signal, and a sufficient amount of time for reproach can be secured.

Further, by outputting a caution signal or a danger signal to the elevator control means, the input of the destination designation button to the underground in the elevator car is invalidated, and the elevator car stops on the ground floor, so that the elevator boarding is stopped. Can be prevented from accidentally moving to the flooded underground.

Further, the control means of the elevator activates the alarm device in response to the input signal from the flow rate detection control means, so that a manager at a remote place can quickly know the emergency at the site.
