Description

Technical Field

[0001] This utility model belongs to the technical field of hydropower plant safety protection system, specifically relating to a multi-measuring-point, multi-elevation linkage system for flood-prone power plant buildings. Background Technology

[0002] Existing monitoring and early warning systems for flooded power plant buildings rely solely on a single sensor for water level measurement, which lacks reliability. Furthermore, existing systems cannot accurately pinpoint the flooded area or quickly issue alarms to alert personnel for evacuation during flooding. Therefore, the problem this invention aims to solve is how to accurately locate the flooded area and issue alarms to promptly evacuate staff during flooding events. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-measuring-point, multi-elevation flood-resistant power plant linkage system, which can accurately locate the flooded area when a flooding event occurs, and send the flooding signal to the monitoring system host computer and issue audible and visual alarms to notify relevant personnel to quickly carry out corresponding emergency handling.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a multi-measuring-point, multi-elevation flood-resistant powerhouse linkage system for hydropower plants, which includes multiple sets of water level monitoring devices installed in the powerhouse, a flood-resistant powerhouse on-site monitoring system, an image monitoring and acquisition system, a fire control system, and a monitoring system host computer; the water level monitoring devices are electrically connected to the flood-resistant powerhouse on-site monitoring system, and the flood-resistant powerhouse on-site monitoring system is electrically connected to the image monitoring and acquisition system, the fire control system, and the monitoring system host computer, respectively.

[0005] The aforementioned water level monitoring device includes a first water level signaler, a second water level signaler, and a third water level signaler with different measurement principles and different output signal types; all three water level signalers are equipped with waterproof sealing measures.

[0006] The image monitoring and acquisition system includes multiple video capture cameras.

[0007] The fire control system includes multiple audible and visual alarms.

[0008] The multiple video capture cameras transmit the captured images to the host computer of the monitoring system through the image monitoring and acquisition system.

[0009] The aforementioned multiple audible and visual alarms will sound an alarm when the fire control system receives a flooded factory alarm signal and a flooded factory shutdown signal.

[0010] When the water level signal received by the flood-proof factory site monitoring system exceeds the preset water level threshold, the system sends a flood-proof factory alarm signal and a flood-proof factory shutdown signal to the image monitoring and acquisition system, the fire control system, and the monitoring system's host computer according to the preset alarm or shutdown logic.

[0011] The main beneficial effects of this utility model are as follows:

[0012] When the on-site monitoring system for flood-proof factory buildings issues a flood alarm signal, it automatically links with the image monitoring and acquisition system for on-duty personnel to perform image recognition, links with the fire control system to issue an audible and visual alarm, and links with the monitoring system's host computer to issue an emergency shutdown signal. This improves the timeliness and accuracy of emergency response by operation and maintenance personnel and minimizes the consequences and scope of impact caused by flooding of the factory buildings.

[0013] The aforementioned water level monitoring device includes three water level signalers with different measurement principles and different output signal types. The on-site monitoring system for flood-resistant power plants performs logical judgments on the multiple water level signals emitted by the water level monitoring device to determine whether the water level monitoring device is malfunctioning or operating normally, thereby increasing the reliability of the multi-measuring-point, multi-elevation flood-resistant power plant linkage system.

[0014] The image monitoring and acquisition system includes multiple video acquisition cameras, all of which are electrically connected to the host computer of the monitoring system. When the on-site monitoring system for the flooded factory building issues a flood alarm signal, the host computer of the monitoring system displays a water level monitoring screen to accurately locate the flooded area.

[0015] The fire control system includes multiple audible and visual alarms, all of which are electrically connected to the upper-level monitoring system. When the on-site monitoring system for flooded factory buildings issues a flood alarm signal, the audible and visual alarms light up and sound an alarm. Attached Figure Description

The flood-resistant powerhouse on-site monitoring system 2 is also electrically connected to the image monitoring and acquisition system 3, the fire control system 4, and the monitoring system host computer 5. When the flood-resistant powerhouse on-site monitoring system 2 issues a flood alarm signal, it automatically activates the image monitoring and acquisition system 3 for image recognition by on-duty personnel, activates the fire control system 4 to issue an audible and visual alarm, and activates the monitoring system host computer 5 to issue an emergency shutdown signal. This improves the timeliness and accuracy of emergency response by operation and maintenance personnel and minimizes the consequences and impact of flooding of the powerhouse.

When the on-site monitoring system 2 for flooded factory buildings issues a flood alarm signal, the host computer 5 of the monitoring system displays a water level measurement point monitoring screen to accurately locate the flooded area.

[0024] In the preferred embodiment, the plurality of audible and visual alarms 10 issue an alarm when the fire control system 4 receives a flooded factory alarm signal and a flooded factory shutdown signal. When the on-site monitoring system 2 for the flooded factory issues a flooded factory alarm signal, the host computer 5 of the monitoring system sends a signal to the audible and visual alarms 10, and the audible and visual alarms 10 light up and sound an alarm.

[0025] In the preferred embodiment, when the water level signal received by the flood-proof factory site monitoring system 2 is greater than the preset water level threshold, the flood-proof factory site monitoring system 2 sends a flood-proof factory alarm signal and a flood-proof factory shutdown signal to the image monitoring and acquisition system 3, the fire control system 4, and the monitoring system host computer 5 according to the preset alarm or shutdown logic, so as to promptly remind the staff to evacuate.
