[0021] Example

[0022] like Figure 1 and Figure 2As shown, the present invention proposes a water level early warning monitoring device, including a flow reduction component, which includes a dam body 1. The dam body 1 is trapezoidal in shape, with its inclined surface positioned at a high water level. The inclined surface of the dam body 1 can deflect the impact force of the water flow. A gate 14 is provided on one side of the dam body 1, penetrating the dam body 1. Multiple gates 14 are arranged in a linear array, selectively transferring water flow from one side of the dam body 1 to the other. A guardrail 15 is provided on the top of the dam body 1 to protect people walking on the top of the dam body 1. A laser detector 5 is provided on the dam body 1 away from the inclined surface, which can be used for preliminary flow warning. A filter component is provided on the dam body 1 away from the inclined surface to isolate large particulate impurities. A floating component is provided inside the filter component for secondary water level early warning.

[0023] For further details, please refer to Figure 2 and Figure 3 The filter assembly includes a measuring box 2, which is fixedly connected to the dam body 1 at a position away from the inclined plane. The measuring box 2 has an installation port 3 at a position away from the dam body 1, through which water can flow. A bottom filter plate 4 is embedded inside the installation port 3, which can filter the water flowing through the installation port 3. A positioning mechanism is provided on the top of the floating block 7. The positioning mechanism is used to fix the position of the floating block 7 and clean the sliding filter plate 10. The positioning mechanism includes a rotating rod 12. There are two sets of rotating rods 12 symmetrically connected to the side of the floating block 7 near the alarm rod 8. The rotating rod 12 can rotate on one side of the floating block 7. A rotating plate 13 is fixedly connected to the end of the rotating rod 12 away from the floating block 7. The rotating rod 12 can adjust the angle of the rotating plate 13. A protrusion 11 is provided inside the positioning plate 9, through which the rotating plate 13 can pass. The protrusion 11 and the rotating plate 13 are correspondingly set. After the rotating plate 13 is adjusted to cross the protrusion 11, the position of the dam body 1 can be fixed.

[0024] For further details, please refer to Figure 3 and Figure 4The floating assembly includes a float block 7, which is slidably connected inside the measuring box 2. The float block 7 can be controlled to rise and fall by the buoyancy of the water flow inside the measuring box 2. An alarm rod 8 is fixedly connected to the top of the float block 7, which can drive the alarm rod 8 to rise and fall. Alarm marks are engraved on the surface of the alarm rod 8, which can be used to sound an alarm. A rotating shaft 16 is rotatably connected to the inside of the measuring box 2 near the top. A positioning plate 9 is fixedly connected to the outside of the rotating shaft 16. The positioning plate 9 can rotate inside the measuring box 2 by rotating the rotating shaft 16. The alarm rod 8 is slidably connected inside the positioning plate 9. A sliding filter plate 10 is fixedly connected to the bottom of the float block 7 near the measuring box 2. The sliding filter plate 10 can work with the bottom filter plate 4 to filter the water flow when the water flow is slow. A top outlet 6 is opened at the top of the measuring box 2 near the installation port 3. The sliding filter plate 10 can block the top outlet 6 to filter the water flow flowing through the top outlet 6 when the water level is high.

[0025] In this embodiment, when in use, the dam body 1 can isolate the river into high water level and low water level, and the inclined surface of the dam body 1 can prevent the pressure and impact of the high water level. The gate 14 can transmit the water flow from the high water level of the dam body 1 to the low water level. The laser detector 5 can detect the flow velocity at the low water level, thereby providing an initial warning.

[0026] When water flows, the installation port 3 can allow the water output from the gate 14 to flow through, while the bottom filter plate 4 can filter the flowing water inside the installation port 3. During heavy rain, the buoyancy of the water flow will cause the float block 7 to float, so the float block 7 can drive the alarm rod 8 to slide along the inside of the positioning plate 9, thus allowing the alarm rod 8 to provide a secondary warning of the water level.

[0027] When the water level rises, the single bottom filter plate 4 has poor flow effect. At this time, the top outlet 6 can be used to transmit water. When the top outlet 6 transmits water, the floating block 7 will cause the sliding filter plate 10 to block the position of the top outlet 6, thereby filtering the water flowing from the top outlet 6. After a period of use, the bottom filter plate 4 can be removed from the installation port 3, and the sliding filter plate 10 can be cleaned by flipping the positioning plate 9 around the rotating shaft 16.

[0028] To ensure easy cleaning of the sliding filter plate 10, the buoyancy of the float block 7 can drive the rotating rod 12 and the rotating plate 13 to protrude from the protrusion 11 inside the positioning plate 9. Then, the rotating plate 13 can be rotated, allowing it to rotate on top of the float block 7 by means of the rotating rod 12, so that the rotating plate 13 and the protrusion 11 form an intersecting shape. This allows the float block 7 to be positioned and connected to the positioning plate 9. Then, the positioning plate 9 can be rotated by means of the rotating shaft 16, thereby causing the sliding filter plate 10 to be tilted, which allows the surface of the sliding filter plate 10 to be cleaned.

[0029] It should be noted that this device uses a floating block 7 to drive the alarm rod 8 to float for secondary warning, while the top outlet 6 can increase the flow of water. When the floating block 7 floats, it will drive the sliding filter plate 10 to seal the position of the top outlet 6. When the floating block 7 is not floating, the sliding filter plate 10 can work with the bottom filter plate 4 to filter the flow of the installation port 3, thereby ensuring the filtration effect when the top outlet 6 is flowing, increasing the filtration effect when the secondary warning is activated and the flow of water is increased.

[0030] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
