Water level monitoring informatization linkage device capable of automatically adjusting measurement range

Abstract

The invention discloses a water level monitoring informatization linkage device capable of automatically adjusting a measurement range, and mainly relates to the field of water level monitoring. The device comprises a base, a main measuring ruler is arranged on one side of the top of an inner cavity; the main measuring ruler is of a hollow structure. One end of a connecting shaft is positioned inthe main measuring ruler; the other end of the connecting shaft is positioned in the inner cavity; a driven bevel gear is arranged at the end, located in the inner cavity, of the connecting shaft. A driving bevel gear is arranged at the output shaft end of a motor; a screw rod is fixed to the end, located in the main measuring ruler, of the connecting shaft, an auxiliary measuring ruler penetrating through the top of the main measuring ruler is arranged in the main measuring ruler, the top end of the screw rod penetrates through the sliding block and is in threaded connection with the slidingblock, a mounting box is arranged on the outer wall of one side of the main measuring ruler, and a water level monitoring device is arranged in the mounting box. The invention has the beneficial effects that the measuring range can be automatically adjusted according to the amount of water, excessive measuring ranges do not need to be set at one time, and therefore the water level can be monitoredmore flexibly.

Description

technical field [0001] The invention relates to the field of water level monitoring, in particular to a water level monitoring information linkage device for automatically adjusting the measurement range. Background technique [0002] The water level is the height of the water surface at a certain point from the standard base. There are two types of standard bases: one is the absolute base, which refers to a certain sea level specified by the country as the zero point of elevation, and the elevations of other locations are all based on this. China stipulates that the base level of the Yellow Sea is an absolute base level. The other is the hypothetical base, which refers to the horizontal base temporarily assumed for calculating the water level or elevation of the hydrometric station. A certain distance below the lowest point of the river bed is often used as the elevation starting point of the station. In order to monitor changes in water level and make timely response me...

Problems solved by technology

[0003] Most of the existing water level monitoring devices are measuring rulers with a fixed measuring range, and the length of the measuring ruler cannot be adjusted according to the water volume. During the rainy season when the water volume rises, the measuring ruler with a fixed measuring range will be submerged by the rising water surface, making it impossible to intuitively To monitor the water volume, if a measuring ruler with a large measuring range is set at the beginning, during long-term use, the upper infrequently used part will be damaged after being exposed to wind and sun, causing damage and making it impossible to continue to use
