Description

Sampling Apparatus for Underground Water

The present invention relates to a water collecting device for an underground water well, and more particularly, to a new water collecting device capable of collecting water at a high depth in the well and safely collecting groundwater at a desired depth.

Groundwater is water that is stagnant or flowing because rainwater or snow that has fallen to the surface penetrates into the ground and is used as a major water resource together with surface water such as river water. value is increasing.

Groundwater has great utility in that it can secure safe water at low cost in a short period of time. However, if groundwater is used excessively than the amount supplemented by rainwater or the water quality deteriorates due to infiltration of pollutants, a long period of time and effort are required for regeneration and recovery. Therefore, it is important to prevent contamination of the wells after developing groundwater and to continuously manage the wells so that a water shortage problem does not occur and a stable water supply is possible. To this end, it is necessary to periodically inspect the water quality not only in new wells but also in existing wells to check for contamination and to eliminate the occurrence of pollutants. In order to inspect the water quality of the groundwater well, it is necessary to collect the groundwater from various depths inside the well.

In general, in order to collect groundwater or groundwater in a deep section, there is a method of collecting water by installing a pump for pumping at the bottom of a water collecting pipe, or attaching a line to a water collecting tank and then lifting it. In particular, when trying to develop groundwater, it is essential to analyze the composition, water quality, and flow rate of the groundwater in the deep well, and for this purpose, it is necessary to collect the groundwater in the section corresponding to the desired depth.

However, the method of collecting groundwater by installing a pump for pumping at the bottom of the water collection pipe requires not only the necessary facilities for this but also consumes electricity, so it costs a lot of money. There is a problem in that it is difficult to collect groundwater of a desired depth because only the water is collected.

For example, according to Utility Model Registration No. 20-0275842, a water collecting device using a water collecting bottle is proposed. A water collecting space is formed in the inner center so that groundwater of a desired depth can be collected through the lower part. a water bottle having an open top/bottom connected to the space; a water collecting hose having an upper portion and one end connected to the water collecting bottle, and the other end being disposed on the ground so that the inside of the water collecting bottle is ventilated; and a check valve installed at the ground end of the water intake hose to open and close the water intake hose to open and close the water intake hose.

In this device, a manual pump is installed at the end of the water collection hose so that groundwater can be collected by manual operation. It is stated that water can be collected through the water hose through the water bottle's water collecting space. However, the vacuum pressure due to the operation of the manual pump can collect only at shallow water depth within the groundwater well, and the amount of water to be collected is very small, so it is difficult to secure an appropriate capacity for checking the quality of the groundwater. impossible.

On the other hand, according to Patent Registration No. 10-1226922, a water collecting device for measuring water quality has been proposed, comprising: a main body comprising a housing attached to a bridge or cantilever and a lifting device installed in the housing; a water collecting unit connected to the lifting device and configured to include a submersible pump for collecting sample water from a river or lake; a hose for transferring the sample water collected by the submersible pump to a measuring station; and a control unit for lifting or lowering the water collecting unit by operating the lifting device.

In this device, a horizontal sensor for detecting the horizontal state of the water collecting unit and a water level sensor for detecting the height of the water surface are installed, and the control unit receives signals from the horizontal sensor and the water level sensor to operate the lifting device, so that the water level is collected at an equal level. However, since it can be installed only in rivers with bridges, it is difficult to apply it to narrow facilities such as groundwater wells, and it is difficult to inject into deep groundwater wells because it includes a submersible pump inside the water collecting part. Not only is it not easy, but there are disadvantages in that the overall system is complicated and expensive to operate and manage.

The present invention has been devised under the technical background described above, and an object of the present invention is to provide a water collecting device capable of collecting groundwater even at a high depth in a groundwater well.

Another object of the present invention is to provide a water collecting device capable of safely collecting groundwater at a desired depth in a groundwater well.

Another object of the present invention is to provide a new water collecting device for underground water wells that does not require expensive equipment such as an external pump or a submersible pump, and the overall system is simple and easy to install.

In addition, other objects and technical features of the present invention will be presented in more detail in the following detailed description.

In order to achieve the above object, the present invention is a structure having an empty interior and extending in one direction, the upper and lower portions of which are partially open, a lower opening and closing opening mounted on the lower part of the pipe-shaped body to open and close the lower surface of the main body; An upper opening/closing opening mounted on the upper part of the pipe-type body to open and closing the upper surface of the main body, a support rod having one end and the other end connected to the lower opening/closing opening and the upper opening/closing opening, respectively, mounted or formed on the upper part of the pipe-shaped body and draining water A first cable connection part for inputting or discharging a water collecting device to an underground water well while enduring the load of the entire device, and an upper opening/closing opening operation part for raising or lowering the upper opening/closing opening with respect to the upper part of the pipe-type body; The lower opening/closing port connected to the support rod opens or closes the lower part of the pipe-type body by the vertical movement of the upper opening/closing port, and when the lower opening/closing port is opened while the water collecting device is put into the groundwater well, groundwater flows into the pipe-type body. Provided is a water collecting device for an underground water well, characterized in that it prevents the outflow of groundwater inside the pipe-type body when the lower opening and closing port is closed.

In the present invention, the upper opening/closing opening operation unit may include a second cable connection part connected to the upper end of the upper opening/closing opening and for raising or lowering the upper opening/closing opening by manually applying tension to the upper opening/closing opening.

Alternatively, in the present invention, the upper opening/closing opening operation unit may include a cylinder connected to the upper end of the upper opening/closing opening and moving the upper opening/closing opening upward or downward by pneumatic or hydraulic pressure.

In the present invention, the pipe-type body may include an upper coupling part in which the upper opening and closing ports are charged, a lower coupling part in which the lower opening and closing ports are charged, and a pipe-shaped intermediate connection part interconnecting the upper coupling part and the lower coupling part. , It is preferable that the upper coupling part and the lower coupling part be formed of a metal such as stainless steel or a material having a higher specific gravity than water and waterproof.

In the water dispenser of the present invention, the lower opening and closing openings are formed in a trapezoidal cross section that decreases in width from top to bottom, and the lower opening and closing ports are charged and coupled to the upper and lower portions of the main body, respectively. Similar to the cross-sections of the lower opening and the upper opening, it is preferable that an inclined surface having a width decreasing downward is formed.

In addition, the present invention may further include a cable winch including a drive motor, a wire reel, the first and second cables wound around the wire reel, and an integrated control unit for controlling the driving speed and direction of the motor, In this case, it is preferable that the first cable and the second cable are simultaneously unwound or wound as a pair from the wire reel by the operation of the driving motor, and the length of the second cable is longer than that of the first cable.

According to the present invention, it is possible to collect groundwater without using a driving pump, thereby simplifying the structure of the overall system, and can be effectively applied to various groundwater wells regardless of location or topography.

The present invention proposes a new water collecting device capable of collecting groundwater at a desired depth of a groundwater well.

Specifically, the water collecting device of the present invention includes a pipe-type body extending long in one direction and having an upper and lower portions open, a lower opening and closing opening and an upper opening and shutting opening respectively mounted on the lower and upper portions of the pipe-shaped body to open and close the lower surface and upper surface of the main body, and the main body A support bar that is charged inside and has one end and the other end connected to the lower opening and the upper opening, respectively, mounted or formed on the upper part of the pipe-type body, and is used for inputting or discharging the water collecting device to the groundwater well while bearing the entire load of the water collecting device. 1 includes a cable connection part, and an upper opening/closing opening operation unit for performing an operation of raising or lowering the upper opening/closing opening with respect to the upper part of the pipe-type body.

In addition, the water dispensing device of the present invention includes a driving motor, a wire reel, a first cable wound around the wire reel and providing tension to the entire water dispensing device, and a second cable providing tension to an upper opening and closing port, and a driving speed and direction of the motor It may further include a cable winch comprising an integrated control unit for controlling the.

The water collecting device of the present invention can collect groundwater without a separate driving pump and is easy to be put into a well-deep groundwater well. Since it is not discharged to the outside, stable underground water collection is possible.

1 schematically shows a water collecting device input to an underground water well. The well (H) formed by excavating deep underground at a specific location of the above-ground part (G) usually has a depth of several tens of meters to several hundred meters depending on the natural water level of the groundwater supplied through the water vein, and is collected below the natural water level (W). A device 10 such as a device or a water quality sensor is put in to determine the water quality. If the device suspended from the cable (C) through the rotary roller (D), etc., from the upper part of the well is put into the well, the weight of the cable is added to the weight of the device itself, and the load of the entire input device is increased, and the In order to put the device in the correct position, precise motion control is required. In addition, in the case of a water collecting device, the collected water should not be mixed with water from other depths or poured out of the device until the desired amount of groundwater is collected from a deep depth in the well and discharged to the outside of the well.

The so-called baler product, which was previously used as a simple water collecting device, is put into a well with a water collecting ball loaded inside a plastic cylinder. The collection was carried out according to this filling principle. This product is only suitable for collecting water from the surface of the natural water level of the groundwater at a low depth (for example, around 5 to 10 meters below the ground). It is impossible to collect water, and moreover, the collected water is easily discharged to the outside of the plastic barrel due to the instability of the collecting ball, so it is not suitable as a water collecting device for water quality management of underground water wells.

The present invention proposes a new apparatus that reliably collects groundwater at a desired depth even at a deep depth and does not require a separate water collection pump or the like. 2 is a side view showing the exterior of the water dispenser of the present invention, and FIG. 3 is a cross-sectional view showing the inside of the water dispenser of the present invention.

The device 100 basically includes a pipe-shaped body 110 and openings and closings on the upper and lower surfaces of the body. The body has an empty interior and is a structure elongated in one direction, the upper and lower portions are partially open (111, 112), and may be formed of a metal material or a plastic material. The lower opening 132 is mounted on the lower part of the pipe-shaped body to open and close the lower surface of the main body, and the upper opening 122 is mounted on the upper part of the pipe-shaped body to open and close the upper surface of the main body. The upper opening and lower openings are made of a metal material with a higher specific gravity than water, so that the closed state of the pipe-shaped body is always maintained by its own weight, and the main body is opened when moving upward by applying an external force.

The upper and lower openings and lower openings are interlocked with each other to control the opening and closing operations of the pipe-type body. For this purpose, the support rod 150 is charged into the body and has one end and the other end connected to the lower opening and closing ports, respectively. includes The support rod is a thin-walled connecting pipe, which may be empty inside, and firmly supports the upper and lower openings and openings by its own rigidity. Make the action work together. To this end, the support rod may be formed of a corrosion-resistant plastic or stainless material that is physically rigid and does not rust.

The water collecting device of the present invention is mounted or formed on the upper part of the pipe-type body and includes a first cable connection part for inputting or discharging the water collecting device to the underground water well while bearing the entire load of the water collecting device. The first cable connection part is, for example, It may be composed of a cable coupling part 140 coupled to the upper end of the body and a cable fixing ring 141 that is additionally coupled or formed on the upper surface of the cable coupling part. The first cable (L1) can insert or discharge the water collecting device into or out of the well while supporting the entire load of the water collecting device, has sufficient length and tension suitable for the depth of the well, and can be wound or unwound by a cable driving device, etc. can be performed.

In addition, the water collection device of the present invention includes an upper opening/closing opening operation unit that raises or lowers the upper opening/closing opening with respect to the upper part of the pipe-type body, which will be described later.

The pipe-type body may include an upper coupling part 120 into which the upper opening/closing opening is charged, and a lower coupling part 130 in which the lower opening/closing opening is charged, respectively. In this case, the upper coupling part and the lower coupling part are a pipe-shaped intermediate connection part can be interconnected with The lower coupling part may be integrated into the pipe-type body, for example, and the upper coupling part may be detachably coupled to the body. The pipe-type body having such a structure can change the capacity of the water collection device according to the amount of groundwater required to be collected in the groundwater well by coupling the intermediate connection part having a different volume or internal space to the upper coupling part. It is preferable that the upper coupling part and the lower coupling part be formed of a metal such as stainless steel or a material that has a higher specific gravity than water and is waterproof. On the other hand, the intermediate connection part may be formed of a metal such as stainless steel or waterproof acrylic. The intermediate connecting portion is formed to have a different length depending on the amount of water to be collected, and the upper end of the intermediate connecting portion may be fastened or separated from the upper connecting portion by screwing. In addition, the lower coupling portion may be integrally formed below the inside of the intermediate connection portion, or may be coupled in a detachable manner to facilitate assembly and disassembly.

In the water collection device of the present invention, it is preferable that the lower opening and closing openings and the upper opening and closing opening are formed in a trapezoidal cross-section having a width decreasing from the top to the bottom. In this case, the surface to which the lower opening and closing openings are charged and coupled to the upper coupling part and the lower coupling part of the main body, respectively, is formed with an inclined surface that decreases in width downward similarly to the cross-sections of the lower opening and the upper opening and closing ports. It is preferable that the cross-sectional structure of the trapezoidal shape reduces friction factors when the upper and lower openings move upward and downward to facilitate separation and engagement. Sealing rings 123, 133, such as O-rings, are coupled to the surfaces of the openings 111 and 112 of the upper coupling part and the lower coupling part to which the upper and lower openings are coupled to prevent the water charged inside the water collecting device from escaping to the outside. it's good

In the water dispenser of the present invention, a stepped portion 142 for limiting the height of the upper movement of the upper opening/closing opening may be formed on the upper surface of the pipe-shaped body. The structure and shape of the step portion may vary depending on the vertical movement method of the upper opening/closing opening. Due to this step, the upper movement distance of the lower opening is also limited by limiting the distance of the upper movement of the upper opening due to this step, and the lower surface of the pipe-type body is sufficiently opened by the vertical movement of the lower opening to allow water from the groundwater well to flow into the main body. It is preferable to determine the height of the stepped portion so as to have a vertical movement gap of the lower opening and closing port.

In the present invention, the upper opening/closing opening operation unit may include a second cable connection part connected to the upper end of the upper opening/closing opening and for raising or lowering the upper opening/closing opening by manually applying tension to the upper opening/closing opening. The second cable connection part may be, for example, a cable fixing ring 124 coupled to the upper end of the upper opening and closing port, to which the second cable L2 is coupled, and to apply tension to the second cable by manual or external force by other devices. The upper opening can be lifted upward by applying

The lower opening/closing port connected to the support rod opens or closes the lower part of the pipe-type body by the vertical movement of the upper opening/closing port, and when the lower opening/closing port is opened while the water collecting device is put into the groundwater well, groundwater flows into the pipe-type body. When the lower opening is closed, the leakage of groundwater inside the pipe-type body can be prevented.

With respect to the water collecting operation, FIG. 4 schematically shows the water collecting process of the water collecting device of the present invention. When the water collecting device is inserted into the underground water well and lowered to a predetermined depth, it falls naturally due to the weight of the water collecting device. will remain sealed. After reaching the desired depth in the well for water collection, the operator pulls the second cable by hand or winds the second cable up by a motor, etc. In the sealed pipe-type body, the upper opening and closing port moves upward to open the upper part 112 and the lower pipe-type body lower part 111 is also opened. In this state, groundwater flows into the pipe-type body by the water pressure of the groundwater in the groundwater well, and when the groundwater is filled in the body, the tension applied to the second cable is released, the upper opening and closing port closes the upper coupling part again by its own weight, and the lower opening and closing opening Also, to seal the lower coupling part at the same time. When the pipe-type body is sealed, the water collecting device is lifted to the top of the well by pulling the first cable while holding the groundwater obtained at a desired depth in the well inside the pipe-type body.

It is also possible to use other means instead of the second cable in this water collecting operation. For example, in the water dispenser of the present invention, the upper opening/closing opening operation unit may include a cylinder connected to the upper end of the upper opening/closing opening and moving the upper opening/closing opening upward or downward by pneumatic or hydraulic pressure. 5 is a schematic view showing a water collecting device equipped with a pneumatic cylinder.

The cylinder 160 has a built-in spring 162 therein, and air is injected through the air supply line 163 from the outside, and by applying pressure in one direction to move the cylinder rod 161, vertical movement of the upper opening/closing opening is performed. can be controlled In this case, the lower end of the cylinder rod is coupled to the upper surface of the upper opening to interlock the movement. In the embodiment shown in FIG. 5, the cylinder rod pushes the upper opening and closing opening downwards by the spring's elastic force to basically maintain the first state in which the upper part of the body is sealed, and by applying air pressure, the cylinder rod moves upward beyond the spring's elastic force. Accordingly, the upper opening/closing opening may also be changed to a second state moving upward. A single-acting pneumatic cylinder may be used to perform the water collection operation by the cylinder action, and it is also possible to use a hydraulic cylinder capable of the same operation.

By the operation of the cylinder, similar to the second cable described above, the lower opening and closing port connected to the support rod by the vertical movement of the upper opening and closing port opens or closes the lower part of the pipe-type body, and the water collecting device is put into the groundwater well. When the lower opening is opened, groundwater flows into the pipe-type body, and when the lower opening is closed, it is possible to prevent the outflow of groundwater inside the pipe-type body. In particular, in the case of such a cylinder method, the advantage of being able to solve the problem that it is difficult for the operator to recognize whether the upper opening and closing there is. In addition, the cylinder method may be advantageous even when implementing a multi-stage water collecting system in which two or more water collecting devices are continuously arranged at different depths to collect groundwater at different depths.

In the water collecting device of the present invention, a plurality of curved buffer parts may be mounted or formed on the outer surface of the pipe-shaped body along the outer peripheral surface in the horizontal direction of the main body. 6 is a side view showing a buffer guide ring 115 on the outer surface of the water dispenser, and a plurality of such guide rings may be disposed at different positions and in different directions on the outer surface of the main body. The guide ring prevents interference with vertical movement due to the protrusion or discontinuity of the inner surface of the well when the water collecting device is put into the well and descends to the depth of the well or rises upward after collecting groundwater, and enables smooth movement.

A separate device may be provided instead of the guide ring. 7 is a plan view showing a guide for inserting a water dispenser, and a separate pipe-type guide may be used instead of a guide ring-type buffer to perform the same function. The pipe-shaped guide 170 has a plurality of curved buffer parts 172 on its outer circumferential surface along the outer circumferential surface in the male direction, and the water collecting device 100 is charged inside the pipe-shaped guide. In this case, it is desirable to prevent the first cable (and other sensor cables, camera cables, etc.) from being twisted by inserting a bearing 174 into the outer circumferential surface of the water collecting device and the inner circumferential surface of the pipe-type guide to prevent the first cable (and other sensor cables, camera cables, etc.) connected to the water collecting device when inputting the groundwater well.

The water collecting device is put into the well by connecting the upper end to the above-described first cable. 8 is a schematic view showing an example of putting a cable into the well from the top of the groundwater well. In general, a well cover 220 is installed in the upper part of the well 210 to prevent the inflow of contaminants. It is possible to enable input and discharge of the water collecting device by lowering or raising the water. The cable driving unit may be equipped with a control unit 302 including a display in addition to the driving motor 301 .

The input and discharge of the water collecting device of the present invention may be induced through a separate device in addition to the conventional cable driving unit. 9 is a plan view showing a cable winch 400 for inserting a cable into a well, in which a driving motor 403, a power transmission unit 404, a wire reel 402 and a control unit 401 are organically coupled, In a state in which the first cable (L1) and the second cable (L2) are wound as a pair, the wire reel is unwound or wound by the operation of the driving motor. As described above, the first cable provides tension to withstand the entire load of the water collecting device, and the second cable provides tension to lift the upper opening and closing opening of the pipe-type body upward, which is stronger than the first cable wound on the cable winch. 2 It is desirable to extend the length of the cable longer. As the second cable is elongated, the first cable fixes the vertical position of the water collecting device in a state in which the cable is released and the water collecting device is inserted to a predetermined depth inside the underground water well, and the operator manually removes the longer second cable by hand. The upper opening/closing opening of the pipe-type body may be lifted upward by pulling or pulling by applying an external force by an external device. If the length of the second cable is the same as that of the first cable, the lifting operation of the upper opening/closing opening is impossible. The cable winch may further include a cable roller 405 including upper and lower rollers to prevent twisting in the process of winding or unwinding the cable, and a tachometer 406 is mounted on the cable roller to win the cable You can check the descending speed or the input length in real time.

The water collecting device of the present invention may further include a camera or a water quality sensor in order to grasp the quality of the underground water at a deep depth, the contamination state inside the well, the cause of the pollutant discharge, etc. in addition to the original purpose of collecting groundwater. 10 is a schematic side view showing a water dispenser equipped with a camera, in which the camera 500 is connected to a support 502 mounted on the lower part of the water dispenser body. The camera can determine the penetration depth of the water collecting device, and the like, and the camera signal cable 510 can be fixed by attaching a separate cable support 501 to the side of the water collecting device.

In addition, multi-item water quality sensors are attached to the upper and lower parts of the water collecting device, or a water level meter can be installed to measure the water quality at the depth of water collection, or to determine the location of the water intake inside the natural water level in the well.

In the above, the present invention has been exemplarily described through preferred embodiments, but the present invention is not limited to such specific embodiments, and various forms within the technical spirit of the present invention, specifically, within the scope of the claims may be modified, changed, or improved.
