The system of the present invention is based on including an upper protective tube (1), an underwater sensor assembly (2), a water collecting assembly (3) and a controller (50).

Specifically, as can be seen from FIGS. 1 to 3 , the upper protective pipe 1 is exposed to the ground by a certain height from the well, similarly to the known upper protective pipe (or upper protective hole), and has a hollow 11 therein. It includes a body pipe 10 having a pipe shape, and a lid 100 for covering or opening an opening of the body pipe 10 (open upper portion of the body pipe).

In the present invention, the main pipe 10 has the same known structure as the upper hole of the upper protection pipe for groundwater wells, so a separate description is omitted, but the open upper part of the body pipe 10 (the upper inlet communicating with the hollow) is ' The 'opening', the side extending curvature along the circumference is called the 'outer peripheral surface', and the empty space inside is called the 'hollow' 11 .

The lid 100 of the present invention has a circular cross-sectional shape corresponding to the shape of the hollow 11 of the body tube 10 having a generally circular cross-sectional shape, and has a certain thickness as a result of a circular plate or a cylindrical shape with a low height take

This lid 10 may not be much different from the well-known lid of the upper protective tube, but it will be described below in a state that combines the role of a rotary pulley that winds or unwinds the first cable 201 on which the underwater sensor 20 is suspended. 1 It may include a special function of rotating by the manipulation of the cable manipulation unit 200, which will be described later.

Referring to FIG. 2 , it can be seen that the underwater sensor assembly of the present invention includes a first cable 201 , a first cable manipulation unit 200 , and an underwater sensor 20 .

The first cable manipulation unit 200 provides a function to wind or unwind the first cable 201 and may have various structures including a known pulley. First, the first cable manipulation unit 200 shown in FIG. 2 is the upper It can be seen that a first pulley 200a installed on one side of the protective tube 1, specifically, one side of the hollow 11 of the main tube 10, and a motor for rotating the first pulley 200a are included.

That is, the first cable manipulation unit 200 rotates the first pulley 200a connected thereto in a forward or reverse direction by driving a motor installed on one side of the hollow 11 while rotating the first cable wound around the first pulley 200a. It performs the function of winding or unwinding (201).

In this case, the motor may control the rotation speed, the number of rotations, and the rotation direction including the speed reducer in a state of being a geared motor or a step motor.

The underwater sensor 20 may perform the same structure and function as a well-known underwater sensor for groundwater in a state mounted on one side of the first cable 201 , preferably at the lower end of the first cable 201 .

For example, the underwater sensor 20 may include a water quality measurement function for measuring water quality in groundwater or a temperature measurement function for measuring water temperature. As mentioned above, the underwater sensor 20 is the same as a known underwater sensor (a water quality sensor or a water temperature sensor, etc.), so a specific separate description will be omitted.

Also, as can be seen from FIG. 3 , it can be seen that the water collection assembly of the present invention includes the second cable 301 , the second cable manipulation unit 300 , and the water collection container 30 .

The second cable manipulation unit 300 provides a function to wind or unwind the second cable 301 and may have various structures including a known pulley, that is, the structure and function of the first cable manipulation unit 200 and the above-described first cable manipulation unit 200 . is installed separately from the first cable manipulation unit 200 except for the installation location in the hollow 11 but may be mounted on the other side of the hollow 11 separated by a predetermined distance from the first cable manipulation unit 200 .

In other words, the system of the present invention provides an underwater sensor 20 and a water collecting container ( 30) is characterized in that it is provided with two operation units called first and second cable operation units (200,300) for operating means for separately raising and lowering.

That is, the second cable manipulation unit 300 shown in FIG. 3 is installed on one side of the upper protection pipe 1, specifically, on the other side of the hollow 11 of the main body pipe 10 away from the first cable manipulation unit 200. It includes a second pulley (300a) and a motor (not shown) for rotating the second pulley (300a).

This second cable manipulation unit 300 rotates the second pulley 300a connected thereto by driving of a motor in the forward or reverse direction as in the first cable manipulation unit 200. The second cable wound around the second pulley 300a ( 301) to wind or unwind. In this case, the motor can also control the rotation speed, the number of rotations, and the rotation direction including the speed reducer in a state in which the geared motor or the step motor is configured.

The collecting container 30 collects, that is, collects groundwater, and provides a function to provide a basis for measuring the water quality of the groundwater more precisely than that measured by the underwater sensor 20 or to check the color, etc. In the state including the housing 31 having a certain volume as shown in detail in the one side, for example, the lower part of the housing 31, the groundwater sample (hereinafter referred to as 'sample') is introduced into the housing 31. It may include a sample inlet 32 that can be introduced.

Such a water collecting container 30 may also be said to be the same as a well-known water collecting container for collecting groundwater, but may include an improved structure capable of collecting water more smoothly, which will be described later.

The controller 50 of the present invention functions to control the driving of the first and second cable manipulators 200 and 300 described above, that is, is mounted on one side of the upper protective tube 1 to perform the first and second operation by an administrator. It may include a function of controlling the rotation speed, rotation direction, and rotation speed of the motor mounted on each of the cable manipulation units 200 and 300 .

4 is a conceptual diagram illustrating an embodiment of a control state for a controller according to the present invention.

Referring to FIG. 4 , the controller 50 controls the underwater sensor 20 and the water collecting container 30 with a touch screen or switch for individually controlling the different operation units, that is, the first and second cable operation units 200 and 300 . It is possible to include a screen as well as a function for controlling the winding speed and winding length of the first and second cable manipulation units 200 and 300 further.

That is, it means that the controller 50 can perform the function of controlling the rising/falling speed and adjusting the depth as well as the function of driving the rising/falling of the underwater sensor and the collecting container.

That is, in the present invention, the term 'auto-winding base' means that the first and second cable operation units 200 and 300 are automatically operated by the controller 50 instead of manually operating the underwater sensor 20 and the water collecting container 30. means you can

In summary, the system of the present invention is provided with first and second cable operation units 200 and 300 that can individually control the underwater sensor 20 and the water collecting container 30, respectively, and is driven by a motor rather than a manual method by an administrator. By supporting the automatic driving method, the respective cables 201 and 301 suspending the underwater sensor 20 and the collecting container 30 are independent of the underwater sensor 20 / collecting container 30 without kinking or collision with each other, that is, It provides the characteristics of providing a basis for measuring the water quality or temperature of groundwater or measuring the water quality of groundwater more precisely by injecting it into or simultaneously injecting it into the groundwater.

5 is a conceptual diagram illustrating a specific structure of a water collecting container.

As can be seen from FIG. 5 , the water collecting container 30 of the present invention may include an improved structure. First, the cylindrical housing 31 extending in the height direction and the end of the second cable 301 . It can be seen that it includes an upper cap 32 that is opened and closed on the upper portion of the housing 31 by having a ring 32a hooked on it, and a sample inlet 33 penetrating through one lower side of the housing 31 .

According to this structure, it is possible to provide a function of more conveniently hanging or mounting the housing 31 to the end of the second cable 301 according to the opening and closing function of the upper cap 32 .

Furthermore, referring to FIG. 5 , a cover 34 and a spring 35 may be additionally mounted inside the housing 31 , specifically, at a position on the upper side of the sample inlet 33 .

The cover 34 is a structure made of a disk (assuming that the housing of the collecting container has a cylindrical shape) having a diameter corresponding to or slightly smaller than the diameter of the hollow of the housing 31 . The cover 34 has a height (thickness) that can open or close the sample inlet 33 .

The spring 35 is installed between the bottom surface of the cover 34 and the bottom surface of the housing 31 to provide a function of exerting elasticity according to the buoyancy force.

That is, when the water collecting container 30 goes deep in the water and buoyancy occurs, the spring 35 expands, that is, rises and raises the cover 34 while opening the sample inlet 33 to introduce groundwater into the housing 31, When the buoyancy force disappears by ascending the collecting container 30, the spring 35 is restored, ie, contracted, and the cover 34 descends and closes the sample inlet 33 to prevent the outflow of groundwater flowing into the housing 31 to the ground level. It can provide a basis for safely transporting the sample.

Previously, it was said that the first cable manipulation unit 200 may have various structures. Hereinafter, a structure in which the first cable manipulation unit 200 is interlocked with the lid 100 capable of performing the function of a rotary pulley is additionally presented.

6 is a conceptual diagram illustrating a further embodiment of the lid of the present invention.

First, based on the three axes of the virtual X-Y-Z axis based on FIG. 6 , the front direction of the main tube 10, that is, the X-axis direction is 'front', 'rear', and the left and right lateral directions, that is, the Y-axis direction is 'lateral' , the up-down direction, that is, the Z-axis direction, is defined as 'up' and 'down'. That is, in the present invention, it is necessary to mobilize three axes for the extension direction of the shaft, which will be described later, for a quick understanding.

The lid 100 of FIG. 6 has a circular cross-sectional shape corresponding to the shape of the hollow 11 of the body tube 10 having a generally circular cross-sectional shape, and has a certain thickness as a result of a circular plate or a cylindrical shape with a low height take

This disc-shaped lid 100 is not much different from the known lid covering the upper part of the known upper protective tube 1, but it is seen that it has a structure that can directly wind (wind) the first cable 201. The main feature of the invention.

In addition, based on the state in which the lid 100 is closed to the opening of the main tube 10, the upper surface (outer surface) exposed to the outside is 'outer surface', the inner lower surface (inner surface) is 'inner surface', between the outer surface and the inner surface The plane extending along the perimeter in

The lid 100 according to FIG. 6 performs the same function as a rotary pulley on which the first cable 201 is wound.

As is well known, a general rotary pulley is a pulley with a string or string wound around a groove recessed in the side of a circular plate (a circular plate is defined as consisting of the top/bottom side and the side between the teeth), so that the disc rotates and the string rotates. It plays a role in transferring power by moving, winding, and unwinding.

The rotary pulley mounted on the lid 100 according to FIG. 6 has a structure such as a roll or a winder, and measures various conditions such as water quality of the well at the end or one side in a state with rotational performance. It provides the function of winding the cable equipped with several survey sensors for

At this time, the first cable operation unit 200 is connected to one side of the outer (outer peripheral surface) of the main tube 10 and the outer surface of the lid 100 to open and close the lid 100 in the main tube 10, as well as the lid ( 100) performs a function of rotating the lid 100 to perform the function of the rotary pulley.

The first cable manipulation unit 200 can automatically open/close the lid 100 by the controller 50 including the aforementioned motor, and a more specific structure will be described later along with the accompanying drawings. .

Figure 7 is a cross-sectional view showing the closed state of the lid of the upper protective tube of the present invention, Figure 8 is a cross-sectional view showing the open state of the lid of the upper protective tube of the present invention, Figure 9 is the lid of the upper protective tube of the present invention It is a cross-sectional view showing a vertically standing state in an open state.

7 to 9, it can be seen that the improved detailed structure of the first cable manipulation unit 200 of the present invention is shown.

First, assuming that the structure including the pulley 120 rotatably protruding from the inner surface of the lid 100 in a state in which the lid 100 is in the form of a disk is referred to as the first embodiment, the lid 100 and the pulley 120 The first cable operation unit 200 is rotatably connected to the center so that the cable is loosened or wound by clockwise/counterclockwise rotation of the lid 100 .

To this end, the first cable manipulation unit 200 includes a first rotating unit 210 rotatably connected to the central portion of the outer surface of the lid 100 .

Referring to FIG. 7 , a first rotating part having a hinge structure and a rotating shaft (shaft mentioned in the first embodiment) 121 extending in a direction perpendicular to the surface of the lid 100 from the central portion of the outer surface of the lid 100 . 210 may be coupled to rotate the lid 100 while the rotation axis is rotated (rotated around the Z axis in the X-Y-Z axis described above) with respect to the first rotating unit 210 .

At this time, the first rotating unit 210 may include a motor (not shown) to automatically rotate the lid.

As a result, the lid 100, in particular, the pulley 120 rotates with respect to the first rotating part 210 in the state in which the lid 100 is opened from the main tube 10, while winding or unwinding the cable, that is, charging or lay the groundwork for salvage.

Specifically, as a first embodiment for the aforementioned rotary pulley, the first rotary part 210 is connected to the lid 100 and the pulley 120 via the rotary shaft 121 to rotate the rotary shaft 121 to the lid ( 100), in particular, the pulley 120 can be rotated, and the first rotating part 210 as a separate embodiment, that is, the second embodiment is connected to the lid 100 via the rotating shaft 121 as a medium to the rotating shaft 121 It means that the lid 100 can be rotated by rotation of .

Furthermore, the surface of the lid 100 is vertically disposed from the opening surface of the main tube 10 so that the first cable is stably directed in the direction of gravity, as well as providing convenience in opening and closing the lid 100, in Fig. As can be seen from 7 to 9, the first cable manipulation unit 200 may include the second and third rotating units 220 and 230 and a plurality of shafts connecting them.

Specifically, the first cable manipulation unit 200 may include first to third rotation units 210 , 220 , 230 , and first to third shafts 240 , 250 , and 260 .

When this detailed structure is described with reference to FIGS. 7 to 9 , the second and third rotation parts 220 and 230 are arranged in the order from the first rotation part 210 connected to the outer surface of the lid 100 and the rotation shaft as a medium, and the first , Between the first shaft 240 between the second rotation part 210 and 220, the second shaft 250 between the second and third rotation parts 220 and 230, and the third rotation part 230 and the outer peripheral surface side of the main tube 10 A third shaft 260 is disposed.

Here, the second and third rotating parts 220 and 230 are made of a hinge (preferably made of a known toothed hinge or stopper hinge having teeth on the outer circumferential surface for angle adjustment while preventing infinite rotation) and manually rotated or the first rotating part ( As in 210 , a separate motor may be additionally provided in the hinge-based structure to be automatically driven by manipulation of the controller 50 .

Specifically, the first shaft 240 extends from the center of the first rotation unit 210 to the top (vertical direction from the top surface of the first rotation unit) and is bent 90 degrees to extend parallel to the outer surface (top surface) of the lid 100 . is the axis At this time, the first shaft 240 extends to a portion past the outer surface of the lid 100 so that the second and third rotating parts 220 and 230 and the second and third shafts 250 and 260 to be described later are constant on the outer peripheral surface of the body tube 10 . It has a base that can be spaced apart.

The second rotation unit 220 is a hinge structure rotatably connected to the end (outer end) of the first shaft 240 , that is, a hinge that is different from the first rotation unit 210 only in the installation direction and has the same or similar structure.

As can be seen from FIG. 9 , the second rotating unit 220 rotates the first shaft 240 (rotating about the Y axis in the X-Y-Z axis described above), and as a result, the outer surface or inner surface of the lid 100 is the front or rear surface Performs a function of rotating the lid 100 so as to look at.

By this second rotation unit 220, the lid 100 can be switched from a lying state (a state horizontal to the opening surface of the main tube) to a standing state (a state perpendicular to the opening surface of the main tube), and its recessed groove 110 The first cable 201 wound around the lid 100 is rotated and released based on the first rotating part 210 and more stably enters the hollow 11 of the main tube 10 along the direction of gravity. .

The second shaft 250 extends along the downward direction parallel to the outer circumferential surface of the main tube 10 from one side of the second rotating part 220 in the front-rear direction of the main tube 10 (X-axis direction in the X-Y-Z axis described above) It is an extended axis bent along the In this case, it is sufficient if the bent extension portion of the second shaft 250 is coupled with a third rotating part 230 to be described later to transmit the rotational force to the second shaft 250 . In other words, when dividing the second shaft 250 into a first portion and a second portion that is a portion bent and extended from the end of the first portion, the first portion is preferably formed longer than the second portion.

The third rotating part 260 is a hinge rotatably connected to the lower end of the second shaft 250 so that the lid 100 can be opened and closed in the opening of the main tube 10, and this is also different only in the installation direction, but the first , 2 may be formed of a hinge structure that is the same as or similar to the rotating parts 210 and 220 . In addition, the rotation direction of the second shaft 250 by the third rotating part 230 may be referred to as a direction along the X-axis in the above-described X-Y-Z axis (ie, rotation about the X-axis).

The third shaft 260 is a shaft that is bent and extended from one side of the third rotating part 230 and connected to one side of the outer circumferential surface of the main tube 10 . That is, the third shaft 260 is supported by the body tube 10 and operates the first to third rotating parts 210,220,230 and the first and second shafts 240 and 250, and as a result, the lid 100 is moved in various directions. It provides a basis for rotation.

In summary, the first cable manipulation unit 200 of the present invention performs a three-axis rotation of the lid 100 in the X, Y, and Z axes by the first to third rotating parts 210, 220, 230 to various positions of the lid 100. It provides a function of winding or unwinding the first cable 201 more simply, conveniently, and stably by changing the angle with the .

As described above, the recessed groove 110 of the lid 100 provides a space in which the first cable 201 is wound. At this time, the first cable 201 is the recessed groove 110 only when measuring the information of the well. ) may be wound on or it is always wound on the recessed groove 110, so it can be used immediately when measuring the well. If the first cable is always wound in the recessed groove 110 , an opening/closing cover (not shown) may be mounted on the inlet side of the recessed groove 110 to protect the first cable.
As described so far, the configuration and action of the upper protection pipe system for groundwater wells including the automatic winding-based underwater sensor and water collecting device according to the present invention are expressed in the above description and drawings, but this is only an example and is not the case of the present invention.
