Description

Technical Field

[0001] This invention relates to the field of water conservancy project safety monitoring technology, and in particular to a multifunctional monitoring and alarm device for seawalls and reservoirs. Background Technology

[0002] As vital water conservancy infrastructure, the safe and stable operation of seawalls and reservoirs is of paramount importance. In production operations within seawall and reservoir areas, water level fluctuations and the displacement and settlement of superstructures are key factors affecting safety and efficiency. In recent years, influenced by global climate change and geological activity, extreme weather events and natural geological disasters have become more frequent, leading to greater uncertainty in water level fluctuations in seawall and reservoir areas. Simultaneously, geological and meteorological factors such as heavy rainfall and earthquakes can easily trigger serious safety hazards such as dam failures, structural displacements, and crack propagation, posing a severe challenge to the safety of water conservancy projects.

[0003] Currently, monitoring methods for the water level and structural safety of seawalls and reservoirs mainly include manual inspections, traditional water gauge observations, and automated monitoring systems based on single sensors. However, these traditional methods have the following shortcomings: Limited monitoring methods: Existing monitoring systems often focus on monitoring a single parameter, such as only water level changes or structural displacement, lacking the ability to comprehensively analyze information from multiple sources, making it difficult to fully assess safety risks; Data lag: Manual inspections and traditional water gauge observations suffer from long data collection cycles and poor real-time performance, making it difficult to meet the needs for rapid response to sudden water level changes and structural anomalies. Insufficient early warning capabilities: Existing monitoring systems lag behind in early warning mechanisms, often only issuing alerts after a disaster has occurred, failing to provide effective early warning information before potential risks occur, thus missing the best opportunity for emergency response.

[0004] Traditional methods for monitoring water levels and structural displacements largely rely on manual inspections, which suffer from drawbacks such as slow response, strong subjectivity, and limited monitoring content, failing to meet the high safety standards required for modern production operations. Furthermore, the feasibility of manual inspections is significantly reduced in adverse weather and environmental conditions, increasing operational risks. Therefore, there is an urgent need for an efficient and reliable monitoring and alarm device for water level and structural displacement changes to achieve real-time monitoring and early warning of water levels along seawall boundaries.

[0005] For example, existing utility model patent document No. 202420095151.9 specifically discloses a reservoir dam flood control and flood season water level monitoring and alarm device. The device is fixed to the bottom of the reservoir via a base, and uses self-monitoring components and auxiliary monitoring cameras to monitor the water level. It is also equipped with a water-blocking plate and a water-guiding channel to reduce the impact force of water flow on the rods. This device improves the convenience and safety of monitoring work to a certain extent. However, this device is not suitable for fixed monitoring in waters with soft soil layers or deep seabeds, has insufficient corrosion protection, is susceptible to seawater erosion, poses risks to underwater power use, and lacks monitoring of displacement changes in the dam and superstructure. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-functional monitoring and alarm device for seawall and reservoir areas that can monitor water level and superstructure displacement changes in a timely, accurate, and multi-parameter manner, issue early warning signals before potential dangers occur, improve the safety management level of seawalls and reservoirs, minimize disaster losses, and protect the safety of people's lives and property.

The upper end of the water level sensing rod passes through the end cap and cooperates with the signal sensor. A first alarm point, a second alarm point, and an electromagnetic buoy are installed on the water level sensing rod. The electromagnetic buoy moves up and down along the water level sensing rod.

A water outlet hole 15 is provided on the upper side wall of the support plate 2, and a wire passage hole 16 is provided inside the support plate 2. The wires of the Beidou monitoring receiver 1 are connected to the alarm 5 and the battery 17 through the wire passage hole 16.

[0022] Furthermore, the outer wall of the lower body 11 is provided with scale lines 12. With scale lines 12, the water level can be observed externally.

[0023] Furthermore, a waterproof gasket 23 is provided on the lower part of the end cap 29 on the outer wall of the water level sensing rod 26. With the waterproof gasket 23, water is prevented from entering the upper body 7 through the perforation in the middle of the end cap 29.

[0024] Furthermore, a filter screen 28 is provided at the lower opening of the lower body 11. With the filter screen 28, debris can be prevented from entering the lower body 11.

[0025] Furthermore, a lower triangular annular clamp 10 is provided on the outer wall of the lower main body 11. The lower main body 11 can be fixedly installed on the structural sidewall within the water area by means of the lower triangular annular clamp 10.

[0026] This invention discloses a multifunctional monitoring and alarm device for seawalls and reservoirs. A Beidou monitoring receiver 1 (its specific structure is existing technology and can be directly purchased from the market) and a camera 3 are installed at the top. The Beidou monitoring receiver 1 and camera 3 are fixedly installed on the support plate 2 at its upper and lower positions via fixing holes 14. A water outlet 15 is provided on the upper side of the support plate 2 to drain accumulated water. The support plate 2 is fixed to the top surface of the upper body 7 by connecting rods 4. A distributed alarm 5 is installed on the upper end of the upper body 7, with the distributed alarms evenly distributed around its perimeter. Equipped with an alarm horn and alarm lights that illuminate yellow and red, the system can issue a warning signal for a set period of time (e.g., the horn sounds for 5-30 seconds and the yellow light illuminates) or a continuous alarm signal for a long period (e.g., the horn sounds for 3-5 minutes each time, pauses, then continues for 3-5 minutes, lasting for 30 minutes, and the red light illuminates). The upper body 7 has waterproof photovoltaic charging line through-holes 218 and backup power supply through-holes 320 on its surface. Inside the upper body 7 is a partition plate 19 with through-holes, and a signal sensor 22 is installed in the space below the partition plate 19. The upper part is equipped with a battery 17, which provides power to the Beidou monitoring receiver 1, camera 3, alarm 5, signal sensor 22, etc. The upper body 7 is equipped with an upper triangular ring clamp 9. The photovoltaic panel 6 is mounted on the upper triangular ring clamp 9 through a support rod 8. The inner wall of the lower opening of the upper body 7 is provided with an internal thread, which is connected to the outer thread of the end cap 29 of the lower hollow cylindrical lower body 11 for a sealed and waterproof threaded connection. The lower body 11 is equipped with a lower triangular ring clamp 10 to fix the equipment to the side structure. The surface of the lower body 11 is provided with externally observable water level. The scale line 12 is located on the lower body 11. A water level sensing rod 26 and an electromagnetic float 27 are installed inside the lower body 11 for water level monitoring. The water level sensing rod 26 is equipped with a first alarm point 24 and a second alarm point 25. The upper part of the water level sensing rod 26 passes through the upper body 7 and is connected to the signal sensor 22. A filter screen 28 is installed at the lower end of the lower body 11 to block debris from entering the cylinder. Depending on the environmental needs, one or more lower bodies can be connected to the lower part of the lower body 11 to increase the height of the entire device. The two lower bodies 11 can be connected by threads or welding.In use, the device is fixed to the structural sidewall of the water body using a lower triangular ring clamp 10 (generally installed on a stable hydraulic structure without significant settlement displacement, such as the sidewall of a dam). The Beidou monitoring receiver 1 and camera 3 on the top of the device extend a certain height above the water body structure plane. Water in the water body can enter the lower body 11 through the lower opening. Under normal water level conditions, the water level is below the bottom of the lower body 11 or only submerges a part of the lower body 11. At this time, the electromagnetic float 27 supported by the water level has not reached the alarm value, and the alarm 5 is not activated by the signal sensor 22. During extreme weather or high tide, the water level will gradually rise, pushing the electromagnetic float 27 to float up along the water level sensing rod 26. When the electromagnetic float 27 reaches the first alarm point 24, the electromagnetic float 27 and the first alarm point 24 magnetically cooperate, causing the number of electronic components connected to the circuit inside the water level sensing rod 26 to increase. When a change occurs (the specific principle is based on existing technology), a signal is sent to the signal sensor 22, which will trigger the alarm 5 to issue a warning signal. When the electromagnetic buoy 27 reaches the second alarm point 25, the signal sensor 22 will trigger the alarm 5 to issue a long-term continuous alarm signal. Under normal circumstances, the Beidou monitoring receiver 1 will not trigger the alarm 5. However, under extreme conditions, such as typhoons, tsunamis, earthquakes, and collisions with large ships, when the structure in the area experiences settlement and large displacement, the Beidou monitoring receiver 1 will transmit signals and trigger the alarm 5. When usable, it will monitor the changes in the amount of structural deformation and displacement for reference in subsequent repairs and use. In addition, the camera 3 can record daily production and life under normal circumstances. When severe weather conditions or extreme events occur, the camera 3 can be used to observe the real-time situation on site.
