Abstract

The invention relates to the field of seawater index detection devices, and provides a liquid concentration detection device. The liquid concentration detection device comprises a concentration detection mechanism and a cleaning mechanism, the concentration detection mechanism comprises a measuring cylinder and a laser displacement sensor, a gravitometer is arranged in the measuring cylinder, andthe measuring cylinder is provided with a gravitometer locating piece for locating the gravitometer; the laser displacement sensor is arranged over the measuring cylinder, a laser emitting direction of the laser displacement sensor is same as a length direction of the gravitometer, and the laser emitting direction faces towards a top end of the gravitometer; the cleaning mechanism comprises a drain pipe communicated with the bottom of the measuring cylinder and a flush pipe for flushing towards the top end of the measuring cylinder, a drain valve is arranged on the drain pipe, a flushing end of the flush pipe faces towards an opening part of the top end of the measuring cylinder, and the flush pipe is provided with a water pump. The liquid concentration detected by the liquid concentrationdetection device is highly accurate. The invention also provides a seawater concentration detection set, the seawater concentration detection set comprises the liquid concentration detection device,and thus, salt pond concentration detected by the seawater concentration detection set is also highly accurate.

Description

technical field [0001] The invention relates to the field of seawater index detection equipment, in particular to a liquid concentration detection equipment and a seawater concentration detection set. Background technique [0002] The existing liquid concentration detection usually calculates the liquid concentration by observing the height of the hydrometer floating in the liquid with the naked eye. When the position of the observer's eyes relative to the hydrometer changes, the data value read by the observer will also change. Therefore, the numerical error read by naked eye observation is large, which makes the measured liquid concentration error large; and after the detection, the device is reused again, because the crystallization or impurities inside the device will cause the concentration of the liquid to be measured to change when it is detected again. There are large errors in the measured results. [0003] Moreover, in recent years, with economic development and s...
