Description

Technical Field

[0001] The utility model relates to the field of early warning devices, in particular to an automatic early warning device for dangerous situations in rivers. Background Art

[0002] Water conservancy projects are projects used to control and allocate natural surface water and groundwater for the purpose of eliminating harm and promoting benefits. Water is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] The patent document with announcement number CN212963568U discloses a water level warning device for water conservancy projects, which states that "it includes a mounting base plate, the lower surface of the mounting base plate is connected to a fixing bolt, the upper surface of the mounting base plate is connected to an electric control box, the side of the electric control box is bolted to a side mounting rod, one side of the side mounting rod is provided with a limit groove, one side of the side mounting rod is provided with a waterproof detection box, the top of the waterproof detection box is provided with a connecting mechanism, and the interior of the waterproof detection box is provided with a water level monitoring mechanism". However, when it is used, the warning water level often changes with the change of seasons and the different regional water conservancy development. Since it has been pre-set in a fixed position and cannot be changed, it is impossible to change the position synchronously with the water level to issue a warning, and the staff cannot directly observe the water level on site during the inspection.

[0004] For example, a water level warning device (publication number: CN218121095U) of the patent includes a warning box, a mounting rod is arranged on the side of the warning box, an observation plate is connected to one side of the warning box, a guide plate is connected to one side of the warning box, and a guide sleeve is connected to the bottom of the warning box; under the action of the indicating mechanism, the measuring float of the utility model can drive the pointer to point to the scale line at the corresponding position when it moves with the water surface, so that the staff patrolling the shore can directly understand the water level through the observation plate, which ensures that the staff's observation is more intuitive and increases the practicality of the device; under the action of the adjusting mechanism, the position of the measuring float can be adjusted by rotating the threaded sleeve, so that the measuring float can adapt to the changes in the water level in different seasons, ensuring more accurate water level measurement, and there is no need for the staff to reinstall the warning box, saving manpower.

[0005] The above patent ensures more accurate water level measurement through the indicating mechanism and the observation plate. In daily use, due to the large change in rainfall in heavy rain weather, the staff cannot timely understand the change of river liquid level and issue an early warning, which makes the application scope of the device small. Therefore, it is necessary to invent an automatic early warning device for river danger to solve the above problem. Utility Model Content
