Description

Groundwater core cleaning device and cleaning method using vertically driven brush {APPARATUS AND METHOD FOR CLEANING TUBULAR WELL USING TOP AND BOTTOM DRIVING BRUSH}

The present invention relates to a groundwater core well cleaning device and a cleaning method, and more particularly, to a groundwater core well cleaning device and a cleaning method using a vertically driven brush that can clean the inner wall of the groundwater core well only by the vertical movement of the brush.

Groundwater core wells usually excavate the rock below the ground surface and use groundwater from the rock aquifer to install groundwater core pumps in the groundwater wells to pump groundwater.

In general, the groundwater flowing in the crushed joint layer formed in weathered rock or soft rock layer flows into the groundwater core well and is used by pumping it. As the groundwater flows in the crushed joint layer, sand or clay components flow into the groundwater core well It builds up on the bottom of the heart and becomes a slime. In addition, some groundwater wells may form sludge by the accumulation of rock powder separated from the excavated hollow walls at the bottom of the groundwater wells. In addition, if the groundwater well is used for a long time, suspended matter or foreign matters are entangled in the excavated vacant walls of the groundwater well, and this phenomenon is entangled in the depth of the entire section where the water level is changed by the groundwater level change caused by the operation of the groundwater well pump. The phenomenon occurs. In particular, in the case of groundwater wells installed on roads, groundwater level drops when the groundwater well pump is operated, and air for volume compensation is inhaled. Black smoke accumulates on the surface of the excavation walls and is entangled. Moss is formed on the excavation walls of some groundwater wells or internal well materials inserted therein, and foreign substances separated from them accumulate on the bottom of the groundwater wells to form slime. Sometimes. Although very small, crickets inhabit large quantities, and their carcasses form sediment, resulting in slime, and decayed debris that attaches to the wall of the heart and continuously contaminates groundwater quality.

These slimes and tangled foreign substances contaminated the inside of the groundwater well and consequently deteriorated the quality of the groundwater, making it difficult to maintain the sanitary groundwater well.

In order to prevent this phenomenon, the groundwater wells in use should be periodically cleaned of the groundwater wells to remove the slime from the bottom of the groundwater wells as well as the excavation walls.

The present inventor has progressed a lot of technology for the efficient and economical internal cleaning of the groundwater heart well, which is patent No. 10-0338257 (patent name: groundwater heart vein cleaning device and cleaning method using liquefied carbon dioxide), Patent No. 10-0714431 (Patent name: Groundwater core cleaning device and method by brush and washing water), Patent No. 10-0856784 (ground water core cleaning device and cleaning method using cooling device and fixed breaker), etc. The company proposed a device and method to clean the inside of the groundwater wells, and the results of technology development have been achieved and applied in industrial sites. In addition, another method for cleaning the inside of some groundwater core wells is Patent No. 10-0531470 (Patent Name: Groundwater cleaning device and its cleaning method through plane spraying and vacuum suction) Also, the general internal water well cleaning is In this case, the air pipe that can supply and supply compressed air is lowered to the bottom of the groundwater core and then injected with high-pressure compressed air to discharge the compressed air and groundwater to the ground, along with the slime at the bottom of the groundwater core. In addition to being discharged, the groundwater excavation walls are also cleaned by the discharged groundwater and compressed air.

However, these conventional methods have the following problems.

Groundwater core cleaning method using liquefied carbonic acid gas has a problem that the liquefied carbonic acid gas injection device that requires a separate expensive not only need to be prepared, but also requires a high level of technology in operation, which has a lot of restrictions in the actual operation.

Groundwater treatment method using compressed pressurized air or high pressure jet water is effective in exposed excavation walls because the groundwater level is below, but the efficiency of compressed high pressure compressed air or high pressure jet water drops rapidly below the groundwater level. In addition to the problem, the complexity of the device configuration was inevitable because the driving force had to be secured from the ground to obtain rotational force.

The groundwater cleaning method using a brush that has the highest direct cleaning effect has a high cleaning effect. However, if you want to get the rotational force to rotate the brush inside the groundwater core, the rotational power of the driving motor is synchronized with the cleaning device such as a brush. There was a problem that the characteristics are rotated in the same direction together. In order to rotate the brush, it is necessary to obtain the rotational force from the ground so that the drilling equipment is put into the field and the fixed rod made of the steel pipe with the brush attached to the bottom is extended or the electric motor is replaced with the brush at the bottom of the drilling equipment. It took the form of installation. Moreover, it is possible to carry out the work in the renovated place due to the equipment input, the installation of the landing rod and the pipe pipe, but most groundwater wells are installed inside the administrative building, the basement floor of the building, or concrete upper protection workers. Since it is installed in the vicinity, it is impossible to add or install the excavation equipment, but the cleaning with the brush has a limit in its application despite the high effect. Patent application No. 10-2007-, which has the function of maximizing the effect of using the brush having high washing effect and preventing the synchronization rotation by using the fixed breaker on the groundwater core wall for washing using the brush without adding equipment. No. 0001982 (groundwater core cleaning device and cleaning method using coordination rotation prevention device to apply pressure to groundwater well wall), but this prior art also requires a separate device configuration to operate the fixed breaker, in particular to rotate the brush Difficulties in the construction, operation and management of the drive motor

The present invention is to solve the above problems, it is possible to clean the groundwater core drilling hole wall while installing the excavation equipment or the driving motor on the ground, or without the installation of the steel pipe landing rod or pipe pipe reciprocating linear brush An object of the present invention is to provide a groundwater cleaning device and a cleaning method using a vertically driven brush.

Groundwater core cleaning device using a vertical drive brush according to the present invention for achieving the object as described above, the brush is provided with a plurality of bristles in the circumference; A flexible connection member connected to the brush to insert the brush into the groundwater well; A drum for winding or loosening the connection member to adjust the position of the brush; Drive means for receiving power to rotate the drum in both directions; It characterized in that it comprises a controller for controlling the bi-directional rotation of the drum through the drive means to raise and lower the brush.

The groundwater core cleaning method using a vertically driven brush according to the present invention includes the steps of removing foreign substances on the inner wall of the groundwater core by the brush bristles of the brush by lowering a brush having a plurality of brush bristles into the groundwater core. Lifting the brush to remove foreign substances on the inner wall of the groundwater core by brush heads of the brush; After the withdrawal of the brush to the ground characterized in that it comprises the step of discharging the foreign matter and ground water collected in the groundwater heart to the ground.

According to the groundwater heart cleaning device and the cleaning method using the vertically driven brush according to the present invention, to clean the inside of the groundwater heart well obtained by using a rotating brush to simplify the various devices that are complicated to obtain the rotational force of the existing brush The effect is the same, but the workflow is simple. Therefore, the groundwater core can be cleaned at a lower cost than before, and even if the groundwater core is located inside the basement of a building or inside a concrete manhole, the technology can effectively and efficiently clean the groundwater core without any obstacles. The effect was obtained to secure.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, and may be changed according to the intention or custom of the producer, and the definitions thereof should be made based on the contents throughout the present specification.

In addition, the terms or words used in the present specification and claims are consistent with the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain the invention in the best way. It must be interpreted as meaning and concept.

Groundwater heart cleaning device using a vertical drive brush according to the present invention, the brush 10 is provided with a plurality of brush bristle 11 at the periphery; A flexible wire 20 for supporting the brush 10 and for inserting the brush 10 into the groundwater core 1; A drum 30 wound around the wire 20; Drive means 40 for rotating the drum 30 in both directions; Then, the controller 50 is configured to control the driving of the driving means 40.

Brush 10 is to wash the inner wall of the groundwater core (1), a plurality of brush bristle 11 is formed in the periphery.

Since the brush bristle 11 scrapes the inner wall of the groundwater core well 1 to remove foreign substances, the diameter of the brush 10 including the brush bristle 11 should be larger than the diameter of the groundwater core well 1, and thus, the brush. The parent 11 secures the flexibility to bend inside the groundwater core 1.

The brush bristle 11 may be a synthetic resin rod, wire, or the like, and may be fixed to the brush body 12 by various methods such as attachment.

The brush body 12 is preferably a cylindrical structure that can accommodate a large number of brush bristle 11, may be a structure formed by rolling the plate in a cylindrical shape, or may be formed in a cylindrical shape by injection or the like.

Brush 10 should not be suspended in groundwater due to buoyancy by groundwater in groundwater core well 1, for example, the weight will be determined so as not to float in groundwater. The method of weighting the brush 10 may be accomplished by changing materials, thicknesses, and the like.

At this time, if the brush 10 is clogged structure, even if it is not floating in the groundwater by weight, the sedimentation rate will be slowed by slowing down the sedimentation rate, so that the brush 10 is preferably a hollow body having upper and lower portions penetrated therein.

As the brush 10 is raised and lowered, the brush 10 may rotate in place when the inner wall of the groundwater core 1 is cleaned. The wire 20 may not be twisted even when the brush 10 is rotated. Brush 10 is connected to brush 10 via a coupler 21 which is rotatably supported in place.

The wire 20 is aligned by one or more guide rollers 22 such that the brush 10 is disposed in the center of the groundwater core 1. The guide roller 22 may be installed at a predetermined height spaced apart from the ground surface through the support 23.

On the other hand, a separate weight 60 (see Fig. 2) may be used in addition to the method of weighting the weight of the brush 10.

The weight body 60 is preferably suspended from the upper part of the brush 10 so that it can be cleaned by the brush 10 to the bottom of the groundwater core 1, for example, to the brush body 11 through the connecting rod 61. Can be connected. In addition, since the weight 60 will vary depending on the amount of groundwater, the weight of the brush 10, etc., the weight 60 is detachably mounted to the connecting table 61 through fasteners such as bolts.

The weight 60 is connected to the wire 20 through the coupler 21.

The wire 20 refers to a connecting member that supports the brush 10 and adjusts the position of the brush 10. The wire 20 is wound around the drum 30 to raise or lower the brush 10 while lowering the brush 10. It can be made of flexible fabric, synthetic resin, or chain. That is, as long as the wire 20 can be wound around the drum 30, everything can be used.

The drum 30 is a cylinder for winding the wire 20, and is installed on the ground around the groundwater core 1, for example, via the base 31. The drum 30 is rotated in place in the forward direction (counterclockwise with reference to FIG. 1) and the reverse direction (clockwise with reference to FIG. 1) by the driving means 40.

The drive means 40 is connected to the drive motor 41, the drive shaft of the drive motor 41 and the drum 30 in which the drive shaft rotates in the reverse direction to the forward direction by receiving the positive and negative polarities, thereby reducing the rotational force of the drive motor 41. It is composed of a power transmission member 42 for transmitting to the drum (30).

Although the power transmission member 42 is shown as a belt in the figure, the power transmission member 42 is not limited to the belt, and everything that can transmit the rotational force of the driving motor 41 to the drum 30, such as a gear train, is used. It is possible.

The controller 50 controls the driving and rotation direction of the drive motor 41.

The present invention cleans the inner wall of the groundwater core well (1) while the brush (10) moves up and down, and thus the controller (50) allows the forward and reverse rotations of the drive motor (41) to be repeated. That is, when the drive motor 41 rotates forward, the brush 10 descends to clean the inner wall of the groundwater core well 1, and when the drive motor 41 rotates reversely, the brush 10 rises while the brush 10 rises. Clean the inner wall.

As such, when the groundwater core 1 is cleaned by raising and lowering the brush 10, the brush 10 should be moved (falled) to the next cleaning section, and the falling distance and the rising distance of the brush 10 are the same. If so, the brush 10 is lowered to the next cleaning section.

Alternatively, the cleaning and movement by the brush 10 may be configured to be performed at the same time, which may be achieved by changing the falling distance and the rising distance.

For example, as shown in FIG. 3, when the ratio of the falling distance A and the rising distance B is 2: 1, for example, the brush 10 repeatedly cleans while descending and rising, and naturally the groundwater core 1 It moves from the ground side of the surface to the floor.

If the brush 10 reaches the bottom of the groundwater core 1, it can be drawn to the ground naturally while cleaning the groundwater core 1 with the falling distance and the rising distance in the opposite ratio.

The controller 50 controls the lifting distance of the brush 10 based on the rotation time of the drive motor 41. Because, the rotation time of the drive motor 41 is the basis for calculating the change in the angle of the drum 30, the change in the angle of the drum 30 becomes the basis for calculating the change in the length of the wire 20 This is because the lifting distance of the brush 10 can be estimated through the length of the wire 20.

On the other hand, when the brush 10 is lowered and reaches the bottom of the groundwater core 1, the brush 10 is configured to automatically rise, for this purpose is provided with a load sensor (S1), for example.

The load sensor S1 detects the load applied to the brush 10 in real time and applies the detected value to the controller 50, and the controller 50 is based on the load change (the brush 10 has the core 1). When the bottom reaches the bottom, the load decreases, and it is determined that the brush 10 has reached the bottom of the groundwater core 1, and the rotation direction of the drum 30 is reversed.

The load sensor S1 may be installed in the guide roller 22.

Since the guide roller 22 is installed through the support 23 and the wire 20 passes, the load of the brush 10 is transmitted, and thus, the load change of the brush 10 can be accurately detected.

In addition, when the cleaning of the groundwater core well 1 is completed and the brush 10 approaches the ground, the limit sensor S2 for detecting the position of the brush 10 is provided on the ground side so that the driving motor 41 may automatically stop. Is installed.

The present invention refers to a pressure for cleaning the inner wall of the groundwater core well (1) by the physical force of the brush bristle 11 of the brush 10, and at the same time to remove foreign substances on the inner wall of the groundwater well (1). It is not limited to a specific value) may be configured as follows to spray the air of the groundwater core well (1) to help remove foreign substances.

As shown in FIG. 1 or FIG. 2, the brush 10 is formed with a plurality of injection holes 13 communicating with the inside and the outside.

The air injection means 70 injects air to the inner wall of the groundwater core 1 through the injection hole 13.

Air injection means 70 is the air compressor 71, the supply pipe 72 for transporting the air supplied by the air compressor 71, the ring is made of the annular while being supplied with air through the supply pipe 72 of the brush 10 It consists of one or more injection pipes 73 for injecting through the injection hole (13).

The supply pipe 72 may be a tube made of flexible rubber or synthetic resin, and may be laid without a separate support on the ground, having a length that is allowed to fit the depth of the groundwater core 1, or wound around the supply pipe drum 74. The structure may be loosened by the lowering of the brush 10. At this time, when the brush 10 is raised so that the supply pipe 72 is automatically wound on the supply pipe drum 74, the supply pipe drum 74 in one direction (the direction of winding the supply pipe 720) by a spiral spring (not shown) or the like. It may be elastically supported to rotate.

Injection pipe 73 will be inserted into the interior of the brush 10, it is preferable to be formed in the same annular shape as the interior of the brush (10). Of course, the injection pipe 73 will be equipped with holes, nozzles and the like communicating with the injection hole 13 of the brush 10 along the circumferential direction.

A coupler 75 is interposed between the supply pipe 72 and the injection pipe 73 to prevent the supply pipe 72 from being twisted.

In the figure, reference numeral 2 denotes a casing 2 for preventing the collapse of the groundwater core well 1. Of course, since the casing 2 is not related to the technical gist of the present invention, the present invention is not limited to being usable only where the casing 2 is installed.

Groundwater core cleaning method using a vertical drive brush according to the present invention is as follows.

In order to clean the inside of the groundwater well (1), first, the pumping pipe (not shown) and the well pump (not shown) installed inside the groundwater well (1) are lifted to the outside and removed, and the inside of the well (1) is empty. It is in a state. Of course, in the case of a newly excavated groundwater core well (1) it may be said to just put a brush (10).

Casings 2 (non-public pipes (not shown) and oil pipes (not shown) made of plastic pipes) are installed inside the groundwater core well (1) to protect the core facilities from accidents such as depression inside the core well (1). If installed, of course, the inner wall surface is cleaned.

Brush 10 is introduced into the groundwater core 1 that is empty inside.

Before driving the brush 10, the driving of the brush 10 is set by determining and inputting a control value of the driving motor 41 according to the falling distance and the rising distance of the brush 10.

When the driving of the driving motor 41 is started, as described above, the driving motor 41 repeats the forward rotation and the reverse rotation, and accordingly, the drum 30 repeats the forward rotation and the reverse rotation of the brush 10. ) Repeats falling and rising.

During this process, the brush bristle 11 of the brush 10 scratches the inner wall of the groundwater core well 1 to remove foreign substances.

In addition, the compressed air is injected to the inner wall of the groundwater core 1 through the injection pipe 73 of the air injection means 70 to remove foreign substances.

That is, the foreign matter adhering to the inner wall of the groundwater core well 1 can be cleanly removed by the brush bristle 11 and the compressed air.

Brush 10 is, as described above, the falling distance is set longer than the rising distance is to move to the bottom of the groundwater core (1) while cleaning the foreign matter.

At this time, even if the brush 10 rotates in place, the wire 20 and the supply pipe 72 are not twisted through the couplers 21 and 75, respectively.

When the brush 10 descends and is seated on the bottom of the groundwater core 1, a change in the load value detected by the load sensor S1 occurs, and the controller 50 drives the brush 10 to rise. Remove the motor 41.

The brush 10 may rise and fall while repeatedly performing the cleaning operation by repeatedly raising and lowering (however, the rising distance is set longer than the falling distance).

When the brush 10 rises and reaches the limit sensor S2, the controller 50 stops driving the driving motor 41.

Subsequently, the brush 1 is withdrawn from the groundwater core 1 and the foreign matter and groundwater collected at the bottom of the groundwater core 1 are removed to the ground. Removal of foreign matter and groundwater may be made by compressed air injected into the groundwater core well (1).

This completes all cleaning procedures.

On the other hand, when there is a section that requires intensive cleaning, the brush 10 may be repeatedly raised and lowered through the controller 50 in the corresponding section.

In addition, the hygienic descaling agent may be put into the groundwater core well (1) to remove the scale attached to the inner wall surface of the groundwater core well (1) during the washing process.
