Mechanical decontamination type water level alarm device and use method thereof

Abstract

The invention provides a mechanical decontamination type water level alarm device and a use method thereof, and belongs to the field of alarm devices. The mechanical decontamination type water level alarm device comprises two supporting frames, an alarm lamp is installed at the top end of one side of one supporting frame, and water level detection probes used for detecting the river water level are installed at the bottom and in the middle of one side of the other supporting frame; a flood prevention mechanism is arranged between the two supporting frames. By arranging a limiting mechanism, a bowl-shaped paddle can rotate under the action of water flow or flowing wind, then a brush is driven to rotate to be matched with an annular spring to drive the brush to move up and down, and the brush can clean the ends of the water level detection probes in the moving process; most scales on the end parts of the water level detection probes can be cleaned, the scales on the water level detection probes are prevented from influencing the detection precision of the water level detection probes, and the problem that the measurement precision of the sensor is influenced by the scale easily generated on the surface of the sensor when the sensor at a low water level is soaked in river water for a long time in long-term use is solved.

Description

technical field [0001] The invention belongs to the field of alarm devices, specifically, an alarm device for specified accidents or abnormal situations, and further relates to a mechanical decontamination water level alarm device and a method of use thereof. Background technique [0002] The water level alarm refers to the alarm of the water level by means of mechanical or magnetic induction. It can be sound and light alarm or magnetic alarm. There are many methods, which vary according to the selection of different products. Controlled by the controller, the principle of the electronic water level switch is to detect the water level through the electronic probe, and then process the detected signal by the special chip for water level detection. When the measured liquid reaches the action point, it outputs a high or low level signal. Then cooperate with the water level controller to output the relay switch signal, or directly supply power to the alarm, so as to realize the ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the rivers need to install multiple water level alarms to detect the water level of the river. Most of the water level alarms use water level electronic sensors to detect the water level of the river. Most of the water level alarms used in the river are installed with Two water level electronic sensors, one high and one low, respectively detect the high water level and low water level of the river in the river. When the water level is lower than the low water level sensor, the alarm sounds to remind people that the water level is too low. When the water level submerges the high water level sensor, The alarm sounds, raising the water level of people to exceed the warning line, but under long-term use, the sensor at a low water level is soaked in the river water for a long time, and scale is easily formed on the surface, which will affect the measurement accuracy of the sensor
