Description

Technical Field

[0001] The utility model relates to the technical field of pressure monitoring, in particular to a reservoir dam pressure monitoring device. Background Art

[0002] Reservoir dam pressure monitoring is a real-time monitoring of the water pressure inside the reservoir to prevent damage to the dam and the surrounding environment due to excessive dam pressure. At the same time, by monitoring the dam pressure, we can more reasonably plan the scheduling and irrigation tasks of the reservoir. The emergence of dam pressure monitoring sensors provides strong technical support for reservoir dam pressure monitoring.

[0003] In the current pressure monitoring of many reservoirs and dams, especially many small reservoirs, not much investment is made in pressure monitoring. Sometimes only one-time monitoring is carried out at special times, and there may be monitoring signals and imperfect facilities, which lead to the data information not being transmitted in real time. This poses a great safety hazard to the reservoir dam and the surrounding environment. At the same time, if the pressure sensor probe falls off due to operational errors or unknown underwater conditions, then searching and salvaging the probe will increase the monitoring cost.

The processor box 11 is used to receive, process and send signals. The left side of the processor box 11 is fixedly connected to the right end of the transmission pipeline 10. A drive motor 25 is arranged at the bottom of the inner cavity of the pressure monitoring chamber 12. The drive motor 25 facilitates the placement and recovery of the pressure gauge cable 14. The driving end of the drive motor 25 is fixedly connected to a connecting block 24. One end of the connecting block 24 is fixedly connected to a cable shaft 23, and the cable shaft 23 is wound around the upper middle part of the pressure gauge cable 14.

[0025] A vertical pipe 13 is provided inside the dam body 1, and a pressure gauge cable 14 and a solenoid valve cable 22 are arranged inside the vertical pipe 13. The pressure gauge cable 14 transmits the electrical signal monitored by the pressure sensor 16, and the solenoid valve cable 22 transmits the electrical signal to the solenoid valve 19. The vertical pipe 13 is used to place the pressure gauge cable 14 and the solenoid valve cable 22. The upper ends of the pressure gauge cable 14 and the solenoid valve cable 22 are fixedly connected to the bottom of the processor box 11.

[0026] Working principle: During the monitoring process, the pressure sensor 16 will monitor in real time and transmit the data to the processor box 11 through the pressure gauge cable 14. The data will be analyzed in the processor box 11, and the analysis results will be transmitted to the background, and at the same time transmitted to the pressure relief control room 2 on the side. When a signal of a high dam pressure value is detected, the signal processing of the processor box 11 will transmit the information to the background for reminder, and transmit the signal to the pressure relief control room 2. At this time, the yellow warning light 3 of the pressure relief control room 2 will light up, and wait for the background command to prepare for pressure relief. When the background does not respond and the pressure value is already too high, the processor box 11 will continue to alarm the background and immediately transmit the pressure relief command to the pressure relief control room 2. At this time, the pressure relief control room 2 will turn off the yellow warning light 3, turn on the red warning light 4 and sound an alarm through the alarm 5 to remind the surrounding people to evacuate in time, and then start pressure relief measures such as opening the gate to release water. The situation is quite critical at this time, so the signal sent by the processor box 11 to the pressure relief control room 2 is all transmitted by wire installed in the transmission pipeline 10 to ensure that there is no delay in response.

[0027] In order to carry out long-term real-time monitoring of the reservoir dam pressure 24 hours a day, the first solar panel 7 and the second solar panel 8 are installed to supply power to the pressure relief control room 2 and the pressure monitoring room 12 respectively, to ensure that the real-time monitoring will not be interrupted due to insufficient power supply. The pressure sensor 16 has been working at the bottom of the dam body 1 for a long time, and the impurities such as phytoplankton in the reservoir may affect the monitoring data. Therefore, a filter 17 is set at the front end of the pressure sensor 16 to reduce the entry of impurities. At the same time, the impurities inside the pressure sensor 16 are cleaned regularly, and an electrical signal is transmitted to the solenoid valve 19 through the solenoid valve cable 22. At this time, the solenoid valve 19 is opened. , water enters the water inlet pipe 20, and water flows out from the water outlet pipe 15 after cleaning the pressure sensor 16. If the pressure sensor 16 falls off, it will be directly caught by the mesh shell 18, which is convenient for removal and replacement. At the same time, in order to facilitate the inspection and replacement of the pressure sensor 16 and the pressure gauge cable 14, a part of the upper side of the pressure gauge cable 14 is wound around the cable shaft 23. When the pressure gauge cable 23 needs to be recovered, the drive motor 25 installed inside the pressure monitoring chamber 12 will be started first, and then the connecting block 24 will be driven to rotate. The rotation of the connecting block 24 drives the rotation of the cable shaft 23, so that the pressure gauge cable 14 is automatically recovered in the vertical pipe 13.
