Water-level measuring device using gear ratio

Abstract

A water-level measuring device using a gear ratio includes: a water pool filled with a liquid; a plot receiving buoyancy by being floated over a water surface of the liquid filled in the water pool; a cable connected to the plot and extending to the outside of the water pool; a first gear connected with the cable; a second gear connected with the first gear; a weight pendulum connected with the second gear and moving in up and down directions, wherein when a water level of the water pool descends, the weight pendulum ascends due to a weight of the plot, and when the water level of the water pool ascends, the weight pendulum descends due to the buoyancy of the plot.

AI Technical Summary

Benefits of technology

The patent text describes a water-level measuring device that uses a gear ratio to measure water levels. The device includes a water pool, a plot that floats on the water surface, and a cable connected between the plot and the outside of the pool. There are two gears, with one attached to the cable and the other attached to the weight pendulum that moves up and down based on the water level. The weight of the pendulum is greater than the weight of the plot, which is floated on the water level. The device also includes a water-level indicator and a connector for sliding movement. A water-level transmitter is also described. Overall, the device allows for non-powered mechanical measurement of water levels using a gear ratio.

Problems solved by technology

However, these water gauges are problematic as below.

The reflex-type water gauge, the plain glass-water gauge, etc. check a water surface from the outside by observing the water surface through transparent glass, and due to contamination of a glass portion for identifying a water surface or interference with a steam portion, it may be difficult to identify the water surface.

In the case of one or more water pools used in the industrial sites, it may be difficult to apply the water gauge, and thus, the water level is measured by using a measuring device, such as ultrasonic waves, a radar, a laser, etc.

However, the previous water gauge used in the industrial sites has the following problems.

When the water level is measured by using the waves reflected by the ultrasonic waves, the radar, the laser, etc., an error may occur in the measurement of the water level due to diffused reflection generated on a water surface.

Also, vapors or bubbles are generated in a high-temperature environment, and in an environment in which the vapors or bubbles are generated, it may be difficult to use an ultrasonic measuring device.

However, in the case of a region exposed to a hazardous environmental condition, due to for example radioactivity, corrosiveness, and acidity, it may be difficult to manage and maintain the measuring device.

However, in the case of the region exposed to the hazardous environmental condition, due to for example radioactivity, corrosiveness, and acidity, it may be difficult to mount the water-level gauge.
