Description

[0001] APPARATUS FOR OBSERVATION UNDERGROUND WATER [0002]

The present invention relates to a portable groundwater observation device, and more particularly, to a portable groundwater observation device capable of easily carrying a portable groundwater device without using a portable equipment. Therefore, groundwater can be observed even in a mountainous area where transportation equipment and large- (Depth from ground surface to ground water surface) using water temperature, conductivity, pH, and depth of water, and it is also possible to measure the water level The present invention relates to a portable groundwater observation device.

In general, ground water is a part of precipitation that permeates into gaps in the ground and accumulates in the gap between the ground and an unspecified ground located at a predetermined depth from the ground.

The water quality of groundwater is usually clean and clean, but the water quality is gradually getting polluted as the life develops and the industry develops. Especially in the industrial area such as the factory area, groundwater pollution is rapidly proceeded, In fact.

Therefore, people drill groundwater wells indiscriminately to find uncontaminated groundwater, and groundwater pollution is increasing. Therefore, it is urgently required to continuously manage groundwater.

As a method for managing groundwater, several groundwater aquifers are selected in the area where pollution is suspected and the operator directly observes and manages the groundwater.

In order to observe and manage the groundwater, it is necessary to periodically measure the water quality of the ground water such as water temperature, conductivity, vibration, water level, and so on.

Conventional methods for measuring water quality and water level of groundwater include a water temperature measuring instrument for measuring water temperature, a water level measuring instrument for measuring water level, a conductivity measuring instrument for measuring conductivity, a vibration measuring instrument for measuring vibration, and a noise measuring instrument for measuring noise And the measurer repeatedly inserts the above-mentioned instruments into the observation area, measures them, and records the measured values while maintaining the time lag of a certain period of time.

The conventional groundwater observation apparatus includes a probe including a water temperature measurement sensor and a conductivity measurement sensor, a cable connecting the probe, and a controller for controlling the display of the water temperature and the conductivity detected from the sensor of the probe on the display. The water temperature sensor and the conductivity sensor may be provided together in the probe and separately configured as in Patent Document 3.

According to the conventional groundwater observation apparatus, the water temperature and conductivity of the ground water can be automatically detected and displayed by the water temperature sensor and the conductivity sensor, but the ground water measurement is dependent on the manual method. In other words, the scale is marked on the surface of the cable, and the manager checks the scale of the cable directly with the naked eye and writes directly on a separate observation sheet.

That is, in the groundwater observation apparatus according to the related art, it is very inconvenient for a worker to visually confirm the water level of the ground water by manual inspection and manual operation, and it is difficult to manage the water temperature and the conductivity of the groundwater obtained from the observation groundwater observator. This is because water temperature and conductivity of groundwater are automatically sensed and displayed, but the water depth is made by artificial action.

On the other hand, Patent Document 4 is known as a portable groundwater observation device. Patent Document 4 discloses that a pressure sensor is used as a water level sensor. In practice, however, it measures the water depth from the water surface of the groundwater to the place where the sensor is locked, that is, it can not measure the water level from the surface of the ground to the water surface of the groundwater.

Another prior art is to measure the level of groundwater (the depth from the surface of the ground to the water surface of the groundwater), but conventionally there is no technique for automatically detecting both the water level and the water level of the groundwater. Consequently, both the water depth meter and the water level meter should be used There is an inconvenience.

1 and 2, a portable groundwater observing apparatus 100 according to the present invention includes a portable case 10, a probe 20 for detecting data (depth, water temperature, conductivity, pH, water level) A waterproof cable 30 electrically connected to the probe 20 and detachably connected to the probe 20 so that the probe 20 can be used alone, a cable 30 connected to the probe 20 A memory 50 for storing the data of the groundwater detected by the probe 20 and the water level calculated by the controller 40, a memory 40 for storing data of the groundwater level detected by the controller 40, 50, a removable memory port 60 for storing data of groundwater stored in the memory 50 in a removable memory, a rechargeable battery 70 for supplying power to components requiring power such as a probe 20, Operation for setting and setting A panel 80, and a display panel 90 for displaying information such as operation of the device on the screen.

The portable case 10 includes a drum 11 wound with the cable 30 wound thereon, a leg 12 connected to the drum 11 and supported on the ground, A handle 13 connected to the drum 11 or the leg 12 and a control box 14 mounted on the drum 11 and accommodating electronic equipment except for the probe 20 and the waterproof cable 30. [

The drum 11 is configured to be rotatable so as to facilitate winding and winding of the cable 30. For example, the drum 11 includes a fixed drum body and a cylindrical rotor drum rotatably coupled to the drum body, .

The legs 12 and the handle 13 can be integrally formed by, for example, bending a circular pipe to perform two functions.

The control box 14 includes a box body 14a mounted on the drum 11 or the leg 12 and having an opening formed on one side thereof for accommodating the controller 40 and the like, And a lid 14b.

The carrying case 10 is provided with a probe housing unit 15 in which the probe bar 20 is housed in order to prevent damage caused by the shaking of the probe 20 when the portable case 10 is carried. The probe accommodating portion 15 is formed in a tubular shape having an open top, and is fixed to the handle 13 or the like so that the probe 20 is inserted from the top and housed therein.

The probe 20 is mounted in the probe case 21 and the probe case 21 and includes a water depth sensor 22, a water temperature sensor 23, a conductivity sensor 24, a pH sensor 25, A rechargeable battery 26 for the sensor for applying power to the sensors 22, 23, 24 and 25, a sensor memory 27 for storing data detected by the sensors 22, 23, 24 and 25, The sensors 22, 23, 24 and 25 and the sensor memory 27 are electrically connected to the cable 30 (or a computer such as a notebook computer when the probe 20 is separated from the cable 30 and used singly) And a sensor side terminal (28).

The probe case 21 is provided with a space in which the sensors 22, 23, 24, and 25 are mounted, and is water-tightly handled so that groundwater can not penetrate.

The probe case 21 is formed with a screw-threaded socket at an end (a portion with the sensor-side terminal 28) so as to be detachably connected to the cable 30. [

The depth sensor 22 may be, for example, a pressure sensor measuring the depth of groundwater by the pressure of the groundwater, and all sensors having equivalent functions are possible.

The water temperature sensor 23, the conductivity sensor 24 and the pH sensor 25 are each immersed in ground water to detect the water temperature, conductivity and pH of the ground water.

That is, according to the probe 20 of the present invention, since the water depth, the water temperature, the conductivity and the pH can be detected, it is possible to detect the water temperature, the conductivity and the pH according to the water depth by changing the depth of insertion of the water depth sensor 22.

The rechargeable battery 26 for the sensor applies power to the sensors 22, 23, 24 and 25 so that the probe 20 and the cable 30 are not connected to each other but connected to the cable 30, Power is applied to the sensors 22, 23, 24, and 25 even in the state of being connected to the wire.

The rechargeable battery 26 for the sensor can be used for a long time by charging, thereby reducing the cost.

3 shows a case where the probe 20 is separated from the cable 30 and used singly. The probe 20 separated from the cable 30 is exposed to the terminals, and in order to ensure watertightness of the probe, The cap 20a is applied. The connection cap 20a is provided with a wire connection portion 20b which is threadedly engaged with the socket of the probe case 21 and to which the wire 1 is connected.

The sensor memory 27 stores data (depth, water temperature, conductivity, pH) of the ground water detected by the sensors 22, 23, 24 and 25 (the water level is detected by sensors 22, And is computed by interlocking with the insertion depth of the waterproof cable 30], and both of the volatility to be stored after a certain period of time, and the nonvolatile state to be stored before forced deletion by the user can be used.

The sensor side terminal 28 is exposed to the outside so as to be electrically connected to the end of the probe case 21 with the cable 30 or another notebook PC or PC etc. When the cable 30 is connected or other non- Keep watertight.

The sensors 22, 23, 24, and 25 are controlled to sense a predetermined period of time after power is applied.

In addition, the present invention is applied to a GPS receiver 29 for confirming a measurement position of groundwater in accordance with the characteristics of a portable device. The GPS receiver 29 receives and acquires the positional information (coordinates) of the groundwater channel through satellite communication (the GPS receiver 29 is installed in the portable groundwater observation device 100 but the portable groundwater observation device 100 is installed in the groundwater observation device The controller 40 allows the position information (coordinates) acquired by the GPS receiver 29 to be stored in the memory 50 at regular time intervals. In other words, the location of the groundwater observation system is automatically stored and managed without additional work, thereby improving utility and reliability as a portable system. The GPS receiver 29 may be operated only once when power is supplied, but it is not limited thereto. The GPS receiver 29 may operate more than two times with a certain period of time in a state of being supplied with power.

The waterproof cable 30 is used to install the probe 20 in the groundwater observation hole 2 (see FIG. 4). The waterproof cable 30 is made of a flexible material so that it can be carried easily, and the sensors 22, 25 of the probe 20 and the sensor 32 of the probe 20 are connected to the signal line 31 and the cover 32 of the signal line 31, And a cable-side terminal 33 electrically connected to the cable-side terminal 33.

The signal line 31 receives the data detected by the sensors 22, 23, 24 and 25 and transfers the data to the memory 50 and applies the power of the rechargeable battery 70 to the sensors 22, .

The cover 32 covers and protects the waterproofing and the signal line 31.

The method of determining the insertion position of the waterproof cable 30 is as follows.

The first is to describe the scale 34 on the outer circumferential surface of the waterproof cable 30. [ Since the present invention does not detect the water level of the groundwater by looking at the scale 34 of the waterproof cable 40, the scale 34 is not described as a small unit, and for example, Lt; / RTI > That is, the manager checks the scale 34 of the waterproof cable 30 and records the depth of insertion and insertion so that the scale 34 is aligned with the ground surface.

The waterproof cable 30 is inserted at a predetermined depth by a winding motor controlled by the controller 40 although not shown in the drawing. For example, if the administrator sets the insertion depth of the cable 30 to 10 m through the operation panel, the controller 40 controls the driving of the winding motor so that only the cable 30 is inserted for 10 m.

The controller 40 calculates the water level of the groundwater through subtraction of the detection value of the water depth sensor 22 and the insertion depth value of the waterproof cable 30, and the water level, water temperature, conductivity, To be displayed on the screen. The water level C is calculated by adding or subtracting the water depth B by the water depth sensor 22 from the insertion depth A of the cable 30 as shown in Fig.

The memory 50 stores the detected values (depth, water temperature, conductivity, pH) of the sensors 22, 23, 24 and 25 and the water level together.

The removable memory port 60 is connected to the memory 50 while being mounted on the cover 14b of the control box 14 and is equipped with a removable memory (USB, SD card, etc.) 50 are automatically moved. Accordingly, since the portable memory only carries the portable memory and the groundwater data is stored in the portable memory, the portable car can be further enhanced in value because it does not carry the notebook.

The rechargeable battery 70 supplies power to all the configurations requiring power supply, and can be used permanently through charging, thus resulting in cost savings.

The operation panel 80 is disposed on the front surface of the cover 14b of the control box 14 and has various buttons such as a power on / off button and a cable insertion depth setting button.

The display panel 90 can display numerals, characters, special symbols, and the like, and under control of the controller 40, the groundwater level, the measurement depth (insertion depth of the waterproof cable 40), the measured water temperature, ), Station number, and so on.

The portable groundwater observation method according to the present invention is as follows.

1. Set the waterproof cable length.

The insertion length of the waterproof cable 30 is first set in order to observe the quality of groundwater in the groundwater observation hole 2. The manager arbitrarily determines the water level of the groundwater to set the insertion length of the waterproof cable 30. However, since the present invention does not detect the water level of the groundwater with the insertion length of the waterproof cable 30, do. For convenience of explanation, the insertion length of the waterproof cable 30 is set to 20 m, for example. The length of the waterproof cable 30 is set by using the button of the operation panel 80. In addition, the power button is operated to supply power to the sensors.

On the other hand, in order to manage the observation data, it is also possible to input a unique number to the groundwater observation observer.

2. Insert and sense probe.

The probe 20 is inserted until the insertion depth of the cable 30 is 20 m. Insert the cable 30 while checking the insertion depth of the cable 30 through the 20-meter scale 34.

The probe 20 passes through the hole of the groundwater observation hole 2 and is submerged in the groundwater while the water depth sensor 22 measures the water depth from the water surface to the insertion depth of the groundwater and the water temperature sensor 23 and the conductivity sensor 24, The pH sensor 25 measures the water temperature, conductivity and pH of groundwater.

In addition, the GPS receiver 29 receives the geographical location information via satellite communication and stores it in the memory 50. [

The water depth, water temperature, conductivity and pH are measured through the sensors 22, 23, 24 and 25, and the water level is calculated by the following method.

The controller 40 calculates the groundwater level C by subtracting the groundwater depth B from the insertion depth A of the waterproof cable 30. That is, when the insertion length A of the waterproof cable 40 is 20 m and the depth B of the groundwater detected by the water depth sensor 10 is 12 m, 8 m, which is 20 m-12 m, is the groundwater level.

With this method, the temperature, conductivity, and pH of groundwater can be measured by varying the insertion depth of the probe 20.

The probe 20 is detached from the cable 30 and separated from the cable 30. The probe 20 is detached from the cable 30 and is then inserted into the socket 30 having the sensor- The connection cap 29a is screwed into the connection cap 29a and the wire 1 is connected to the wire connection portion 20b of the connection cap 29a so as to be inserted into the observer. When the probe 20 is immersed in the groundwater, Measure water temperature, conductivity and pH. Of course, since the waterproof cable 30 is not used at this time, the sensors 22, 23, 24, and 25 are powered from the rechargeable battery 26 for the sensor, and the measurement data is stored in the sensor memory 27) and does not measure the water level (the depth from the surface to the surface of the groundwater).

When the measurement of the groundwater is completed, the connection cap 29a is disconnected from the probe bar 20 and the connection cable is connected to the sensor-side terminal 28 of the probe bar 20, .
