Description

Technical Field

[0001] This invention belongs to the field of early warning equipment technology, specifically relating to a flood early warning system based on optical fiber communication. Background Technology

[0002] Floods generally refer to the sudden rise and fall of floodwaters along rivers and streams caused by torrential rains, the failure of flood control facilities, and other factors, along with accompanying landslides, collapses, and mudslides. Flood disasters are the harms caused to people by floods, including casualties, property damage, infrastructure destruction, and environmental damage resulting from river flooding, mudslides, and landslides. Flood disasters are primarily influenced by torrential rains; therefore, the occurrence of floods coincides with the occurrence of torrential rains. To detect floods in advance and enable potentially affected areas to take timely measures to minimize loss of life and property, it is necessary to install fiber optic communication-based flood early warning systems in potentially affected areas for real-time monitoring.

[0003] Existing flood warning systems based on fiber optic communication typically predict and issue warnings by monitoring changes in water levels and rainfall. However, these systems face challenges when used in densely wooded mountainous areas, potentially leading to inaccurate flood warnings.

[0004] On the one hand, trees or rocks can affect the transmission of wireless signals, while thunderstorms can affect the transmission of wired data, causing signal distortion.

[0005] On the other hand, the tipping bucket rain gauge is currently commonly used to monitor changes in rainfall intensity and amount. The top of the existing tipping bucket rain gauge is a rain collection port for collecting rainwater, and a filter screen is installed inside the rain collection port to filter out debris.

[0006] Because heavy rain is often accompanied by strong winds, large but lightweight objects such as leaves and plastic bags are easily blown up by the wind and fall into the rain collection inlet, clogging the filter and affecting the flow of rainwater in the inlet, which in turn affects the measurement accuracy and the accuracy of the warning. Summary of the Invention

[0056] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0057] Please refer to the following: Figures 1 to 9The present invention provides a flood early warning system based on optical fiber communication. The system includes a mounting frame 10, a tipping bucket rain gauge 20, a water level meter 31, a current meter 32, a monitoring component 33, and a control box 34. The mounting frame 10 is suitable for installation beside a river. The tipping bucket rain gauge 20 is connected to the mounting frame 10. The water level meter 31 is connected to the mounting frame 10 and is used to monitor the river water level. The current meter 32 is connected to the mounting frame 10 and is used to monitor the water flow velocity in the river. The monitoring component 33 is connected to the mounting frame 10. The control box 34 is connected to the mounting frame 10 and contains a controller and an optical fiber communication module. The controller is connected to the optical fiber communication module to receive monitoring data transmitted from the tipping bucket rain gauge 20, water level meter 31, current meter 32, and monitoring component 33, and transmits the monitoring data to a cloud platform management center and residents' terminals via the optical fiber communication module to issue flood early warning calls.

[0058] The tipping bucket rain gauge 20 has a filter screen 23, a first conveying component, and a second conveying component inside its rain-collecting opening 21. The first conveying component is connected to the filter screen 23 and is used to convey the garbage on the filter screen 23 to the second conveying component. The second conveying component is connected to the rain-collecting opening 21 and is used to convey the garbage to the outside of the rain-collecting opening 21.

[0059] It should be noted that the metering components inside the tipping bucket rain gauge 20 are existing components. The mesh size of the filter 23 is shown in the figure.

[0060] The beneficial effects of the flood early warning system based on optical fiber communication provided by this invention are as follows: Compared with the prior art, the flood early warning system based on optical fiber communication provided by this invention, by adding an optical fiber communication module, can avoid the influence of rocks, trees and thunderstorms on signal transmission, making the signal transmission real and stable; and through the tipping bucket rain gauge 20, water level gauge 31, current meter 32 and monitoring component 33, it monitors changes in river flow and rainfall in real time, and transmits the monitoring data to the cloud platform management center and residents' terminals to make flood early warning calls; and the rain collection port 21 of the tipping bucket rain gauge 20 is equipped with a filter screen 23, a first conveying component and a second conveying component. The first conveying component transports the garbage on the filter screen 23 to the vicinity of the second conveying component, and then the second conveying component discharges the garbage out of the rain collection port 21, thereby effectively preventing the filter screen 23 from being blocked and ensuring measurement accuracy and early warning accuracy.

[0061] like Figure 1 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the mounting frame 10 includes a support rod and several crossbars, with the crossbars spaced apart on the support rod and connected to it.

[0062] Specifically, the mounting frame 10 includes a support rod and two crossbars. The tipping bucket rain gauge 20 is connected to the upper crossbar, and the water level gauge 31, the flow rate gauge 32, and the monitoring component 33 are all connected to the lower crossbar.

[0063] In a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the optical fiber communication module includes an optical signal transceiver component and a data optical fiber. The optical signal transceiver component is connected to the controller. One end of the data optical fiber is connected to the optical signal transceiver component through an optical fiber connector, and the other end is connected to a relay station. The relay station is connected to the cloud platform management center and the resident household terminal for communication.

[0064] like Figure 1 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the water level gauge 31 is an ultrasonic water level gauge 31, used to monitor the water level in the river.

[0065] like Figure 1 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the flow meter 32 is an ultrasonic flow meter 32, used to monitor the flow velocity of water in the river channel.

[0066] like Figure 1 and Figure 2 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the filter 23 has an inverted cone-shaped structure to facilitate rainwater collection and downward flow.

[0067] like Figure 3 and Figure 9 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the first conveying component includes a plurality of actuating components and a first driving component. The plurality of actuating components are arranged at intervals along the busbar of the filter screen 23, and the power output end of the first driving component is connected to the actuating components.

[0068] The actuating assembly includes multiple actuating mechanisms and multiple transmission components 43. The multiple actuating mechanisms are arranged in a ring around the axis of the rain-collecting opening 21, and each actuating mechanism is rotatably connected to the filter screen 23. The multiple transmission components 43 are located between two adjacent actuating mechanisms, and their two ends are respectively connected to the actuating mechanisms. The diameter of the ring formed by the multiple actuating assemblies gradually increases from the inside to the outside.

[0069] It should be noted that the transmission component 43 is a rubber rod, which is fixedly connected to the actuation mechanism at both ends and transmits torque through the rotation of the rubber rod; in addition, the transmission component 43 can also be a connecting rod with couplings at both ends.

[0070] Specifically, such as Figure 3 and Figure 9As shown, in a specific implementation of the flood warning system based on optical fiber communication provided in an embodiment of the present invention, the拨动机构 (stirring mechanism) includes a sliding sleeve 41 and a sliding rod 42. The two sides of the sliding sleeve 41 perpendicular to the axis of the filter screen 23 are rotationally connected to the filter screen 23; the sliding rod 42 is slidably engaged with the sliding sleeve 41. When the sliding rod 42 is in a vertical state, the frictional force between the sliding rod 42 and the sliding sleeve 41 is less than the self-weight of the sliding rod 42.

[0071] More specifically, the included angle between the sliding rod 42 and the horizontal plane is a. When 0 < a < 80°, the frictional force between the sliding rod 42 and the sliding sleeve 41 is greater than the component force of the gravity of the sliding rod 42 in the axial direction of the sliding rod 42. When 80° < a ≤ 90°, the frictional force between the sliding rod 42 and the sliding sleeve 41 is less than the component force of the gravity of the sliding rod 42 in the axial direction of the sliding rod 42. 80° is the critical angle. The numerical value here is only an example, and the specific critical angle can be set according to actual situations and requirements. By changing the materials and surface smoothness of the sliding rod 42 and the sliding sleeve 41, the friction coefficient between the sliding rod 42 and the sliding sleeve 41 can be changed, and thus the critical angle can be adjusted.

[0072] As Figure 3 and Figure 9 As shown, in a specific implementation of the flood warning system based on optical fiber communication provided in an embodiment of the present invention, the first driving component includes a plurality of driven synchronous pulleys 44, a first motor component 47, a driving synchronous pulley 45, and a synchronous belt 46. The plurality of driven synchronous pulleys 44 are arranged at intervals along the generatrix of the filter screen 23, corresponding to the stirring components one by one. The driven synchronous pulleys 44 are connected to the transmission member 43; the first motor component 47 is connected to the rain receiving port 21; the driving synchronous pulley 45 is connected to the power output end of the first motor component 47; the synchronous belt 46 is wound around the driving synchronous pulley 45 and the plurality of driven synchronous pulleys 44.

[0073] It should be noted that during the working process, the first motor component 47 drives the driving synchronous pulley 45 to rotate,带动 (drives) the plurality of driven synchronous pulleys 44 to rotate through the synchronous belt 46, and further drives the sliding sleeve 41 in the stirring mechanism of the plurality of stirring components to rotate; initially, the sliding sleeve 41 is vertically arranged, and the sliding rod 42 extends downward out of the sliding sleeve 41. During the process of the sliding sleeve 41 rotating and带动 (driving) the sliding rod 42 to rotate, the sliding rod 42 rotates from bottom to top, gradually protruding from the surface of the filter screen 23. Continuing to rotate upward, the garbage on the filter screen 23 is拨向 (pushed towards) the outside of the filter screen 23 until it rotates to the critical angle, and then the sliding rod 42 slides downward, effectively avoiding that when continuing to rotate, the sliding rod 42 presses down on the garbage, gets entangled with the garbage, or makes the garbage stuck in the filter screen 23.

[0074] As Figures 4 to 8As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the rain-collecting inlet 21 has an inverted conical structure. The second conveying component includes an inner sleeve 51, a second driving component, and an airbag 60. The inner sleeve 51 is fitted inside the rain-collecting inlet 21 and is located on the upper side of the filter screen 23, spaced apart from the inner wall of the rain-collecting inlet 21 and rotatably engaged with the rain-collecting inlet 21. The top of the inner sleeve 51 protrudes from the rain-collecting inlet 21 and is provided with a baffle 52. A sliding groove is opened on the lower side of the baffle 52. Several sliders 2 are provided on the top of the rain-collecting inlet 21. 2. The slider 22 interacts with the groove; the outer wall of the inner sleeve 51 is provided with a spiral protrusion 54, and the outer wall of the inner sleeve 51 and the inner wall of the rain-collecting port 21 are both provided with an elastic layer 53; the second drive component is connected to the tipping bucket rain gauge 20, and the power output end is connected to the inner sleeve 51 to drive the inner sleeve 51 to rotate; the airbag 60 is located on the lower side of the inner sleeve 51 and is connected to the filter screen 23. The airbag 60 is suitable for cyclic contraction and expansion to push the garbage into the space between the inner sleeve 51 and the rain-collecting port 21, and the garbage is discharged from the rain-collecting port 21 by the rotation of the inner sleeve 51.

[0075] Specifically, the gap between the inner sleeve 51 and the rain-collecting opening 21 is small enough to trap the garbage; the chute is a dovetail groove or a T-shaped groove to restrict the movement of the inner sleeve 51 relative to the rain-collecting opening 21 in the vertical direction.

[0076] It should be noted that the airbag 60 is intermittently supplied with air by an air pump, causing the airbag 60 to cyclically contract and expand. The first motor assembly 47 drives the actuating mechanism to move the garbage to the edge of the filter screen 23, and then the airbag 60 pushes it between the inner sleeve 51 and the inner wall of the rain-collecting port 21. Since both the rain-collecting port 21 and the inner sleeve 51 have an inverted conical structure, the diameter of the inner sleeve 51 gradually increases from the inside to the outside. When the inner sleeve 51 rotates, the linear velocity of each point on the inner sleeve 51 gradually increases from the inside to the outside. Therefore, it will exert an outward pulling force on the garbage sandwiched in the middle, so that the garbage gradually moves outward as the inner sleeve 51 rotates, and is finally discharged from the rain-collecting port 21. Furthermore, a spiral protrusion 54 is provided on the outer wall of the inner sleeve 51 to further facilitate the outward movement and discharge of the garbage.

[0077] Meanwhile, by providing an elastic layer 53 on the outer wall of the inner sleeve 51 and the inner wall of the rain-collecting opening 21, on the one hand, the friction with the garbage is increased, making it easier to roll the garbage into the space between the inner sleeve 51 and the rain-collecting opening 21; on the other hand, the distance between the inner sleeve 51 and the rain-collecting opening 21 can elastically change with the volume of the garbage, avoiding situations such as garbage not being able to be rolled in, garbage being crushed, or garbage getting stuck. Specifically, the elastic layer 53 is made of rubber, silicone, or plastic.

[0078] Furthermore, the lower ends of the inner sleeve 51 and the rain-collecting opening 21 are funnel-shaped, meaning that the distance between the lower ends of the inner sleeve 51 and the rain-collecting opening 21 gradually decreases from top to bottom, so as to clamp the garbage and roll it between the inner sleeve 51 and the rain-collecting opening 21.

[0079] like Figure 1 and Figure 2 As shown, in a specific embodiment of the flood early warning system based on optical fiber communication provided in this invention, the outer periphery of the retaining edge 52 at the top of the inner sleeve 51 is provided with teeth, and the second drive component includes a second motor component 71 and a gear 72. The second motor component 71 is fixedly installed, and the power output end is connected to the gear 72. The gear 72 meshes with the teeth on the outer periphery of the retaining edge 52.

[0080] Specifically, the teeth on the outer periphery of the retaining flange 52 and the teeth on the gear 72 are both helical teeth.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
