As shown, the floating multi-item water quality measurement apparatus according to an embodiment of the present invention includes a device body 110, an ultrasonic diffusion prevention member 120, an air tube 130, a first sensor module SM1, and It comprises a 2 sensor module (SM2), a third sensor module (SM3), a water temperature sensor (S4), an ultrasonic generator 140, a weight ring 150, a remote controller 170.

The floating multi-item water quality measurement device according to an embodiment of the present invention measures DO, pH, EC and water temperature in a water environment such as a river or lake by the above main components to determine what harmful chemicals are spilled. It is configured to be able to be identified as, and to achieve more accurate measurement and lifespan improvement by minimizing the contamination level for each sensor.

Hereinafter, a floating type multi-item water quality measuring apparatus according to an embodiment of the present invention will be described in more detail with reference to each of the above components.

The device body 110 has a cylindrical housing, and a communication module for communication with the outside and a battery for power supply are built into the housing. The lower end of the device main body 110 is made of a removable cover 111 so that the upper surface can be selectively opened, and the battery can be replaced with the upper surface open.

The ultrasonic diffusion preventing member 120 blocks the ultrasonic waves generated by the ultrasonic generator 140 from unnecessarily spreading to the surroundings, thereby inducing the ultrasonic waves to act more intensively on the water quality measurement sensors installed at the bottom of each sensor module. Plays a role. The ultrasonic diffusion preventing member 120 is formed of a porous cylindrical body having a plurality of entrance holes 121 allowing water to enter and is detachably coupled to the lower circumference of the device body 110. To this end, a male screw 112 is formed at the lower end of the housing of the device main body 110, and correspondingly, a female screw 122 is formed inside the upper end of the ultrasonic diffusion preventing member 120.

Here, it is preferable that a mesh network, not shown, is further installed in the entrance hole 121 of the ultrasonic diffusion preventing member 120 to block foreign substances from entering from the outside.

Further, an ultrasonic diffusion preventing diaphragm 160 is installed in a form that crosses the middle of the inner space of the ultrasonic diffusion preventing member 120. When the diaphragm 160 is installed, the internal space of the ultrasonic diffusion preventing member 120 is divided into upper and lower parts, so that the ultrasonic waves generated by the ultrasonic generator 140 are concentrated only under the internal space and provided at the lower end of the sensor module. It is induced to focus only on each water quality measurement sensor. However, the diaphragm 160 is located in the middle of the inner space of the ultrasonic diffusion preventing member 120 with the support bodies of each sensor module, the water temperature sensor S4, and the ultrasonic generator 140 penetrating therethrough.

The air tube 130 is installed on the outer circumferential surface of the apparatus body 110 and serves to provide buoyancy so that it can float on the water surface. The point where the air tube 130 is installed is a suitable upper end of the device body 110, which is preferable to maintain a sense of stability so that the water quality measuring device according to an embodiment of the present invention does not shake or fall from side to side.

The first sensor module (SM1), the second sensor module (SM2), and the third sensor module (SM3) are installed in a form protruding downward from the lower surface of the device main body 110, and each lower part submerged in water has different A first water quality measurement sensor (S1), a second water quality measurement sensor (S2), and a third water quality measurement sensor (S3) for measuring the water quality of the item are respectively installed. Each of the sensor modules includes a first support (SP1), a second support (SP2), and a third support (SP3) having a cylindrical shape extending in a downward direction, and a first water quality that is installed at the lower end of each of the supports to contact water. It consists of a measurement sensor (S1), a second water quality measurement sensor (S2), and a third water quality measurement sensor (S3). The first sensor module SM1, the second sensor module SM2, and the third sensor module SM3 are arranged at equal intervals along the lower circumference of the device body 110 as shown in FIG. 4. In addition, a water temperature sensor (S4) is installed in the center of which the lower part is formed to be elongated in the downward direction so that the lower part can be submerged in water to measure the water temperature.

Here, the first water quality measurement sensor (S1), the second water quality measurement sensor (S2), and the third water quality measurement sensor (S3) are sensors for measuring pH concentration, EC (electrical conductivity), and DO (dissolved oxygen), respectively. It can be provided. According to this configuration, it becomes possible to measure pH concentration, EC, DO, and water temperature at the same time.

The ultrasonic generator 140 serves to clean the surfaces of the first water quality measurement sensor S1, the second water quality measurement sensor S2, and the third water quality measurement sensor S3. To this end, the ultrasonic generator 140 is installed between the sensor module and the sensor module as shown in FIG. 4, and extends downwardly from the lower surface of the device body 110 so that the lower end of the first water quality measuring sensor (S1) ), the second water quality measurement sensor (S2) and the third water quality measurement sensor (S3) to reach the vicinity, and generates ultrasonic waves at the lower end of the ultrasonic generator (140). As such, when the ultrasonic generator 140 is disposed between the sensor module and the sensor module, and installed to generate ultrasonic waves in the vicinity of each water quality measuring sensor, it is possible to increase the cleaning effect of the water quality measuring sensor. Further, since the ultrasonic diffusion preventing member 120 and the ultrasonic diffusion preventing diaphragm 160 described above do not spread the ultrasonic waves unnecessarily and act intensively on each water quality measurement sensor, it prevents contamination of the water quality measurement sensor as much as possible and It is possible to maximize.

The weight ring 150 corrects the weight difference between the first water quality measurement sensor (S1), the second water quality measurement sensor (S2), and the third water quality measurement sensor (S3) so that the water quality measurement device moves to one side from the water surface. It serves to balance so that it does not tilt. To this end, first, the first sensor module (SM1), the second sensor module (SM2), the first support (SP1) of the third sensor module, the second support (SP2), the lower outer peripheral surface of each of the third support (SP3) male screw Is formed. The weight ring 150 is provided with a female screw on an inner circumferential surface so as to be screwed to the outer circumferential surfaces of the first support SP1, the second support SP2, and the third support SP3 formed with male threads. Accordingly, as can be seen in FIG. 2 or 3, the weight ring 150 is fastened to the lower outer circumferential surfaces of each of the first support body SP1, the second support body SP2, and the third support body SP3. In contrast, the difference in weight of the first water quality measurement sensor S1, the second water quality measurement sensor S2, and the third water quality measurement sensor S3 can be corrected by a method of differentially applying the number of fasteners. For example, according to the drawing, since the third water quality measurement sensor S3 of the third sensor module SM3 has a lighter weight than the first water quality measurement sensor S1 or the second water quality measurement sensor S2, the third support ( It can be seen that the number of weight rings 150 fastened to SP3) is applied the most. For reference, in the case of a sensor that is equipped with the first water quality measurement sensor (S1), the second water quality measurement sensor (S2), and the third water quality measurement sensor (S3) to measure the pH concentration, EC, and DO, which one is heavy Since it is different for each manufacturer rather than a fixed one, the weight ring 150 can balance the water quality measurement device so that it does not incline at the water surface when setting the site according to the situation.

The remote controller 170 is connected to the device body 110 by wire or wirelessly, as shown in FIG. 6, a display 171 receiving and displaying data measured by each water quality measurement sensor, and an on-off switch Basically equipped with (172). According to the drawing, the remote controller 170 is shown as being wired to the device body 110 by a wired line (L1), but can be connected wirelessly as much as possible by having a wireless communication module, instead of the remote controller 170 It can also be connected to a smartphone equipped with a dedicated app.

On the other hand, the floating multi-item water quality measuring device according to the embodiment of the present invention described above is a database storing data measured by the water quality measuring device, and any harmful substances based on the data measured by the water quality measuring device according to the hazardous chemical classification criteria. A controller for determining whether a chemical substance has been spilled into the water, a software module for providing a classification criterion for hazardous chemical substances to the controller, and a system for measuring hazardous chemical substances in the water environment may be further included. At this time, the database, the controller, and the software module may be simply mounted on the remote controller 170.

Regarding the criteria for judging hazardous chemical substances, when the chemical substance is an acid, it is characterized by low pH and high EC, and when the chemical substance is a base, it is classified by characteristics of high pH and low EC. In the case of inorganic substances, it was confirmed that they exhibit weak acidity, neutrality, and weak basicity depending on the pH, and it was found that they have lower EC characteristics than acidic substances. In the case of organic matter, it was impossible to measure it as an alternative indicator, so the material was selected using hyperspectral sensor photography.

Through the characteristic diagrams shown in Tables 1 and 2 below, a classification table of hazardous chemicals is prepared based on the water quality items measured by the floating multi-item water quality measuring device, and unknown hazardous chemicals spilled through this standardized program are collected. It is possible to judge.
