Description

[0001] APPARATUS FOR MEASURING SALINITY AND WATER LEVEL [0002]

The present invention relates to a salinity and water level measuring apparatus, and more particularly, to a salinity and water level measuring apparatus installed on a volcanic tide before a salt.

In general, a salt tin is formed by capturing seawater and collecting the salt crystals collected by evaporating the water of the sea water by the solar energy and the wind, and the salt crystals produced by the salt tin are called the sun salt.

Tidal currents are generally divided into reservoirs in which seawater is stored, evaporation sites that evaporate seawater, and deciduous sites where the seawater is evaporated to be collected by salt crystals.

However, since the production of man-made salt is labor-intensive, such as manually measuring the salinity and measuring the level of salinity by manually moving around the worker to measure the salinity and level of the salinity, There is a problem that it is difficult to build a torsion automation facility to save manpower.

In addition, triboelectricity is vulnerable to automation because it is vulnerable to corrosion of mechanical devices due to high salinity and moisture and high electric conduction, resulting in high risk of electrical accidents.

In addition, there is a problem that it is very difficult to build an automated facility because the standard is not standardized, so it is difficult to establish an automated facility because each standard is different for each site even in the same site.

As a result, the production of domestic sun-dried salt is labor-intensive by manual operation from the evaporation site to the salt warehouse storage, and therefore, it is required to construct a torsion automation facility for saving manpower.

1 is a perspective view showing a salinity and water level measuring apparatus according to a first embodiment. FIG. 2 is a schematic view showing the inside of the closed part of FIG. 1, and FIG. 3 is a plan view showing the inside of the closed part of FIG. FIG. 4 is a schematic view showing a load cell connected to the buoyant weight of FIG. 1, and FIG. 5 is a schematic view showing salinity measurement of FIG.

1 to 3, the salinity and water level measuring apparatus according to the first embodiment includes a housing 10, a buoyancy measuring unit 30, a water level measuring unit 50, and a controller 70 .

Here, the salinity and water level measuring apparatus according to the first embodiment is located in the liquid to be measured and measures the salinity and the water level of the liquid. Hereinafter, a salinity and water level measuring apparatus for measuring the salinity and the water level of a salt in a liquid for convenience of explanation will be described.

Each of the buoyancy measuring unit 30, the water level measuring unit 50, and the control unit 70 can receive power from a power supply unit 90 such as a battery. For example, the battery has a capacity to operate a power supply target device such as the buoyancy measuring unit 30, the water level measuring unit 50, and the control unit 70 for about 8 months during which the salt is produced. By using the load cell 33, the infrared distance sensor 51, and the load cell 53 for level measurement, which will be described later in the measurement control, it is not necessary to supply extra power to the measurement non-maintenance. Therefore, the amount of work can be reduced by replacing the battery once a year.

The buoyancy measuring unit 30, the water level measuring unit 50, the control unit 70 and the power supply unit 100 are disposed in the enclosure 13 of the housing 10 to be described later. The buoyancy weight 31 and the connecting body for connection between the buoyancy weight 31 and the load cell 33, which will be described later, And the frame and the housing may be made of plastic or the like of edible material.

The housing 10 is located in a torsion state such as a crystal paper or evaporation paper to be measured and includes a body part 11, a sealing part 13, and a lid part 15.

Here, the housing 10 may have a generally cylindrical shape. In addition, the housing 10 may be formed by integrating the body portion 11, the sealing portion 13, and the lid portion 15.

The body portion 11 is provided with a bottom surface. In addition, a part or the whole of the side portion may have such a shape that brine in the form of brine or the like can enter into and out of the body portion 11. [

The hermetically sealed portion 13 is installed on the body portion 11 so as to be watertightly separated and watertight.

The lid portion 15 is provided on the sealing portion 13 so that the sealing portion 13 is hermetically sealed.

As shown in Fig. 4, the buoyancy measuring unit 30 measures the buoyancy of the torsion. The buoyancy measuring unit 30 is connected to the buoyancy weight 31 and the buoyancy weight 31 which are positioned on the bottom surface of the housing 10, that is, above the bottom surface of the body unit 11, And a load cell 33 disposed inside.

Here, the buoyancy measuring unit 30 can measure the buoyancy of the buoyancy weight 31 by using the weight measuring function of the load cell 33.

That is, the buoyancy measuring unit 30 is configured such that the buoyancy weight 31 is immersed in the salt to be measured and changes in the weight of the buoyancy weight 31 according to the change amount of the buoyancy acting on the buoyancy weight 31 The buoyancy can be measured by the output voltage such as the analysis of the electric signal changed by the voltage. At this time, the load cell 33 has a function of changing the resistance according to the amount of change in the buoyant force acting on the buoyancy weight 31, that is, the variation of the voltage with respect to the applied voltage.

The buoyancy weight 31 is composed of a broad float bottom for receiving buoyancy and a thin and long float top for connecting the load cell 33 to the bottom of the float.

The water level measuring unit 50 measures the level of the salt water.

For example, the water level measuring unit 50 is constituted by an infrared ray distance sensor 51. Here, the water level measuring unit 50 configured by the infrared ray distance sensor 51 may further include a float D when it is difficult to measure the water level.

For example, the level measuring unit 50 may be an ultrasonic distance sensor, not shown. Here, the water level measuring unit 50 configured by an ultrasonic distance sensor may further include a float D when it is difficult to measure the water level.

The float D is disposed inside the body portion 11 between the bottom surface of the body portion 11 and the sealing portion 13 and floats before the salt. In order to reduce the error caused by the float (D), the float (D) can be formed in a thin shape. The float D is installed such that it does not come in contact with the connection body between the buoyancy weight 31 and the load cell 33, such as a donut shape.

The control unit 70 controls and controls the buoyancy measuring unit 30 and the water level measuring unit 50 and calculates the salinity by receiving the measured values of the buoyancy measuring unit 30 and the water level measuring unit 50 do.
