Description

Portable automatic water sampling device with remote control {PORTABLE WATER SAMPLING APPARATUS WHICH CAN BE REMOTE CONTROLLED}

The present invention relates to a portable automatic water sampling device capable of remote control, and more particularly, to a remotely controllable portable automatic water sampling device capable of measuring the level of sewage and wastewater in a sewage pipe from a short distance or a long distance and controlling various measured values and water sampling. It's about the device.

Analysis of the temperature or electrical conductivity of wastewater flowing through sewage pipes, or the temperature, turbidity, pH, DO, COD, TOC, TN, TP, etc. of materials treated in chemical plants or wastewater treatment processes has generally been dependent on manual work.

In other words, as workers sample samples from wastewater in sewage pipes, chemical plants, or multiple points in the wastewater treatment process, the samples sampled may be contaminated or deteriorated due to environmental conditions such as weather or operator mistakes.

As such, the analysis according to the manual work of the operator had a large error due to frequent changes in the sampling period and location, and it was difficult to accurately analyze the sample.

In addition, since the sample to be put into the measuring device is manually processed and manipulated in the pretreatment process to prepare it in an appropriate state, there is a high possibility of erroneous manipulation, and the analysis result may vary depending on the analyst's subjectivity or intention.

Above all, if the analysis results were recorded manually, the reliability was lowered, the possibility of loss or damage of the records was high, and it was more impossible to monitor from a remote location.

From the above point of view, the water sampling device is used to investigate contamination levels, bacteria, organisms, and the like of rivers, lakes, and seas.

Therefore, in view of the recent development of communication technology and technology of portable terminals such as smart phones, it is urgent to develop a device and system capable of providing the convenience of remote control according to connection with these communication devices. .

The separation prevention protection pipe 412 may have an inner circumferential surface facing the outer circumferential surface of the pump pipe 411 .

In addition, a water collection tip module 430 is provided at the distal end of the pump pipe 411 to prevent clogging caused by foreign substances flowing into the sewage pipe 411 and wastewater flowing between the distal end of the pump pipe 411 and the sewage pipe 600. It plays a role in maintaining the communication of

Here, the separation prevention protection pipe 412 is designed to prevent the pump pipe 411 from shaking or being lost due to the rapid increase in flow rate and flow rate of wastewater in the sewage pipe 600, making it impossible to collect water in advance, the pump pipe ( 411) is accommodated inside to help the water sampling pump 410 perform stable water sampling through the pump pipe 411.

Here, the water sampling guide means 460 may include a corrugated pipe 461 that is provided at the distal end of the pump pipe 411 and is flexible to cover or expose the outer circumferential surface of the coil spring 431 .

At this time, the water sampling guide means 460 is built into the pump pipe 411 and is connected to the front end of the coil spring 431, and the front end of the coil spring 431 is connected to the pump pipe 411 according to the water level of the sewage conduit 600. Of course, it may be further provided with an operating wire (not shown) that is pulled up from the distal end toward the distal end of the coil spring 431 or pushes the distal end of the coil spring 431 toward the distal end of the pump pipe 411.

That is, when the water level of the sewage conduit 600 is low, the water sampling guide means 460 exposes the entire outer circumferential surface of the coil spring 431 to prevent weakening of the suction force by the water sampling pump 410 to some extent.

In other words, by manipulation such as reducing or increasing the exposed outer circumferential area of the coil spring 431 by the corrugated pipe 461 or the manipulation wire as described above, water collection operation is performed in accordance with the level of wastewater inside the sewage pipe 600. will be able to proceed.
