Description

The protective apparatus for pipe equipment that supplying subterranean water}

The present invention relates to a well protection device installed in the form of underground buried in order to prevent damage to the wells constructed for the intake of groundwater.

Groundwater, which is cleaner than river or river water, is used for the purpose of living water, agricultural water, and industrial water.

In order to collect and use groundwater, it is essential to construct a well that connects the groundwater to the groundwater source with groundwater.

Previously, small house-shaped jangoks were installed to prevent damage to the wells to collect groundwater.

However, these jangok had a problem that takes a lot of installation cost and occupy a lot of the installation area.

In addition, there was a problem that freezing accidents occur frequently in the groundwater supply line in Jangok during winter.

In order to solve these problems, a protective cover and a protective case, and a tube information protection device (Korean Patent Registration No. 10-0699909, Korean Patent Registration No. 10-0640143, etc.) have been devised to bury most of the protection cases.

However, the conventional pipe information arc device as described above was only to connect the pumping pipe and ground water supply pipe (2) inserted into the well inside the protective case.

Therefore, when the protective cover is removed, the interior space of the well (the space between the outer and pump pipes located at the outermost side of the well) can be seen through the installation space of the protective case. There was a problem.

(In most of the wells constructed recently, the outer tube 3a is positioned, the inner tube 3b is positioned inside the outer tube 3a, and the pump tube 1 is inserted into the inner tube 3b.)

In particular, when opening the protective cover and repairing the facilities inside, the inflow of soil or pollutants generated during the work frequently occurred.

In addition, there are many cases in which the protective case is provided with a hole for ventilation, in which a worm enters the groundwater source through the well.

In addition, there is a lot of precipitation during the rainy season, so the cover may be immersed in rainwater.In such a situation, when rainwater flows into the inside of the protective case, the rainwater flows directly into the groundwater source through the well and leads to contamination of the groundwater source. There was a problem.

The present invention is to solve the problems as described above, it is an object to provide a well protection device that can prevent damage to the well as well as to prevent contamination of the groundwater source.

The device of the present invention is a facility installation space in which various structures can be located is formed, and the lower part is to be buried underground while maintaining the state connected to the well, and when connected to the well to block the top of the well A water pipe insertion hole and a water level measuring sphere are formed so that the facility installation space and the well can be communicated, but the water level measuring sphere has a protective case formed outside the water pump insertion hole;

A protective cover configured to block or open the facility installation space of the protective case;

A wire installation hole is formed which is drilled up and down, and is fixed to the outside of the pump pipe to be inserted into the pipe and integrated with the pump pipe. Pumping tube fixation to prevent falling along the well;

A pumping connecting pipe connecting the pumping pipe located at the pumping pipe insertion port and the groundwater supply pipe to supply groundwater;

One side is connected to the wire installation port and the other is a wire installation pipe extending to the upper portion of the protective case;

One side is connected to the water level measuring instrument and the other side is a water level measuring tube extending to the upper portion of the protective case; is configured to include.

That is, in the present invention, the upper part of the well is blocked by the protective case and the pump pipe fixing body, and the water level measuring instrument and the wire installation port through which the power supply line of the submersible motor are formed to easily measure the water level of the groundwater source are passed. Through the measuring tube and the wire installation tube, the entrance is positioned high at the bottom of the protective case, so that no foreign matter or rainwater flows into the facility installation space of the protective case so that it does not enter the groundwater source.

In addition, the power supply line for supplying power to the underwater motor moves with the pump when the pump is lifted from the well for the purpose of repairing the motor, so that the lifting of the pump is easy.

In addition, to separate and combine the pumping connection pipe connecting the groundwater supply pipe and pumping pipe to simplify the work.

In the device of the present invention, the upper part of the well is blocked by the protective case and the pump pipe fixing body, and the water level measuring instrument and the electric power supply line through which the power supply line of the submersible motor are formed so that the water level measurement of the groundwater source can be easily carried out The entrance is located above the bottom of the protective case through the measuring tube and the wire installation tube, so even if foreign matter or rainwater enters the installation space of the protective case, it does not flow into the groundwater source, preventing contamination of the groundwater source.

In addition, when the pump is lifted from the well for the purpose of repairing the underwater motor, a power supply line for supplying power to the motor is also moved together with the pump to facilitate lifting of the pump.

In addition, it is easy to separate and combine the amniotic fluid connection pipe.

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

1 is a cross-sectional view showing a state in which the apparatus of the invention is installed.

The present invention corresponds to a device for protecting a well, and has a protective case 10, a protective cover 20, a positive connection pipe 30 as in the known art.

The protective case 10 is a facility installation space 11 is formed in which various structures can be located is to be buried underground while the lower portion is connected to the well.

In addition, the protective cover 20 is to be separated and coupled to the protective case 10 to block or open the facility installation space (11).

In addition, the pumping pipe 30 is connected to the pumping pipe (1) and the ground water supply pipe (2) so that the ground water raised on the pump pipe (1) by the underwater motor or the like to be supplied through the ground water supply pipe (2) It is.

By the way, only the above configuration can not achieve the purpose of preventing groundwater contamination, which is the object of the present invention.

In order to prevent the contamination of the groundwater source, even if foreign matter such as soil or rainwater flows into the facility installation space 11 of the protective case 10 , the upper part of the well 3 is blocked so as not to enter the inside of the well 3. Should be.

To this end, the protective case 10 of the present invention can be implemented in the form as shown in Figure 1 to block the upper part of the well (3) when connected to the well (3).

In addition, when the well coupling flange 70 is coupled to the pumping pipe (1), and the well coupling flange 70 and the protective case 10 is connected in a manner that the well coupling flange 70 is the upper part of the well It may be implemented in the form as shown in Figure 6 to block.

Of course, the pump case insertion openings 12 and 72 are formed in the protective case 10 or the well coupling flange 70 so that the facility installation space 11 and the well 3 can communicate with each other.

However, the portions except the pumping tube insertion openings 12 and 72 are blocked by the protective case 10 or the pipe fitting flange 70.

(The protective case 10 or the well-coupled flange 70 may be formed in the water level measuring sphere 14, such a water level measuring sphere 14 is preferably formed on the outside of the pump pipe insertion openings (12, 72). .)

The reason why the pumping pipe insertion holes 12 and 72 are formed is that the pumping pipe 30 should be connected to the pumping pipe 1, and the lifting of the pumping pipe 1 may occur.

It is preferable to form the pump pipe insertion openings 12 and 72 as small as possible.

The reason for forming the water level measuring instrument 14 is to send the water level measuring instrument to the groundwater source to measure the level of the groundwater source or to send various sensors to the lower part of the well 3 to perform various measurement or inspection work. .

Such a water level measuring instrument 14 is preferably formed on the outside of the pumping pipe inserts 12 and 72, but it is necessary to lift the pumping pipe 3 for repair of the underwater motor or the pumping pipe 1, and This is because the operation level is convenient when the water level measuring instrument 14 is not affected.

Unavoidably, the pumping pipe insertion holes 12 and 72 should be blocked when the device of the present invention is installed to prevent foreign substances or rainwater from entering the well 3.

However, since the lifting of the pumping pipe 1 may occur, the means for blocking the pumping pipe insertion ports 12 and 72 may not interfere with the lifting of the pumping pipe 1.

In the present invention to achieve the above object through the pump tube fixed body (40).

That is, the pumping pipe fixing body 40 is fixed to the outside of the pumping pipe 1 to be inserted into the well and integrated with the pumping pipe 1, in the structure as shown in Figure 1 pumping tube insertion opening 12 of the protective case 10 Hanging on the outside of the pumping pipe (1) is to prevent the pumping pipe insertion opening (12) at the same time to prevent falling down along the well (30).

6, the pumping pipe fixing body 40 is caught in the pipe fitting flange 70 and prevents the pumping pipe 1 from descending along the pipe well 30, and at the same time, the pumping pipe inlet 72 of the pipe fitting flange 70. To block.

The pump pipe fixing body 40 is preferably provided with a wire installation port 15, which is connected to the power supply line in order to operate the submersible pump located at the bottom of the pump pipe (1), lifting the pump pipe This is because it is easy to work when the power supply line is not obstructed.

Pumping connection pipe 30 of the present invention is to connect the pumping pipe (1) and the ground water supply pipe (2) located in the pumping pipe insertion opening (12, 72) so that the groundwater is supplied.

By the above configuration, most of the foreign substances introduced into the facility installation space 11 of the protective case 10 can be introduced into the groundwater source through the well.

However, since the wire mounting tool 15 and the water level measuring instrument 14 that are inevitably formed are in an open state, foreign matter or rainwater may flow through the wire mounting tool 15 and the water level measuring instrument 14.

For this reason, the apparatus of the present invention is provided with a wire installation tube 50 and a water level measurement tube 60 extending the inlet of the wire installation port 15 and the water level measuring instrument 14 to the upper portion of the facility installation space 11. have.

One side of the wire installation pipe 50 is connected to the wire installation port 15 and the other is a long form extending to the upper portion of the protective case (10).

In addition, one of the water level measuring tube 60 is connected to the water level measuring sphere 14 and the other is a form extending long to the upper portion of the protective case (10).

Since the wire installation port 15 and the water level measuring tube 60 as described above can be formed small and extend upward, even if foreign matter falls into the facility installation space 11 during the installation or repair work, the wire installation pipe ( 50) or via the water level measuring tube 60 is very unlikely to enter the groundwater source.

In addition, even if a large amount of rainwater flows into the facility installation space 11, the entrance of the wire installation pipe 50 and the water level measurement tube 60 is located higher than the bottom of the facility installation space 11 so that rainwater does not flow.

The upper end of the water level measuring tube 60 is to be located higher than the center of the facility installation space (11).

The upper end of the water level measuring tube 60 may be opened so that the stopper is removed only when used in a state blocked by the stopper.

In addition, the water level measuring tube 60 is preferably as close as possible to the inner wall forming the facility installation space (11).

This is because there is a need to prevent the water level measuring tube 60 protruding from placing various facilities or wires in the installation space 11.

In particular, in the configuration where the water level measuring tube 60 is located higher than the center of the facility installation space 11, it is very important that the water level measurement tube 60 is brought into rapid contact with the inner wall of the facility installation space 11.

The upper end of the wire installation pipe 50 is also preferably located higher than the center of the facility installation space (11). In this case, the wire installation port 15 is preferably close to the pumping connection pipe (30).

This is because there is a need to prevent the wire installation pipe 50 from protruding when placing various facilities or wires in the facility installation space 11.

In FIGS. 1 and 6, the protective case 10 and the pumping pipe 1 are coupled to each other using a pipe fitting flange 70.

Further, the pipe fitting flange 70 has a pipe insertion groove 71 into which the upper end of the outer pipe 3a, which is located at the outermost side of the pipe, is inserted, and the outside pipe 3a of the pipe well 3 is inserted into the pipe insertion groove 71. ) Is welded and integrated.

This configuration has the advantage that the operation of connecting the protective case 10 and the pumping pipe (1) is very simple.

In other words, the device of the present invention is installed in the well that is completed construction.

Therefore, in order to install the device of the present invention, the deep drilling of the ground surface on which the well is installed, it is required to cut off the upper part of the well and connect the cut well and the protective case 10.

By the way, in the prior art, a considerable inconvenience has arisen in the operation of connecting the upper well cut well and the protective case 10.

The biggest reason for this inconvenience is because of its structural characteristics, it was necessary to cut cleanly horizontally when cutting the top of the well.

However, it is never an easy task to have a clean cutting surface while horizontally cutting a well embedded in the ground.

However, if the protective case 10 and the well is connected to the well through the well flange having a well insertion groove as shown in Figures 1 and 6 it is not necessary to cut the well horizontally, it is convenient to work because it does not have a clean cutting surface.

In FIG. 1, a flow passage connecting pipe 80 in which groundwater connector 81 is formed is provided on the side of the protective case 10.

In addition, the flow path connecting pipe 80 is installed to communicate with the inner and outer sides of the protective case 10 through the groundwater connector 81, it is possible to connect the ground water supply pipe (2) from the outer side of the protective case (10) It is to be connected to the pumping connection pipe (30).

This configuration is to facilitate the operation of connecting the pumping pipe (1) in the inner side of the protective case 10 and the ground water supply pipe (2) located on the outer side of the protective case (10).

That is, it is difficult to insert the groundwater supply pipe 2 into the protection case 10 in a state in which the protection case 10 is installed.

In addition, if the ground water supply pipe 2 is inserted into the protection case 10, the sealing work to prevent the inflow of soil or water to the portion into which the ground water supply pipe 2 is inserted is required. Discomfort occurs.

Therefore, the flow path connecting pipe (80) is connected to the protective case (10) and connects the ground water supply pipe (2) to the flow path connecting pipe (80), the operation is easy by connecting the outside of the protective case (10) To do that.

In FIG. 1, the positive connection pipe 30 is bent such that one side faces downward and the other toward side.

In addition, the connection pipe coupling means 90 is provided, but the connection pipe coupling means 90 has a rotating rod 91 which is spirally coupled to the protective case 10 and is rotated before and after rotation, and the rotating rod 91. One end of the positive connector 30 moves in the direction of the flow path connector 80 and the other end of the positive connector 30 moves in the direction of the pump tube 1 as the forward or backward moves. It has an inclined surface to be in close contact with each of the pipe 80 and the pumping pipe (1).

This configuration is not only easy to selectively remove and combine the pumping connection pipe 30, but also minimizes the pressure drop of the groundwater supplied by the submersible pump.

That is, in the related art, in order to facilitate the separation and coupling of the pumping connector 30, the pumping connector 30 is formed in a "∩" shape, and the pumping connector 30 is pressed by the protective cover 20. There were many cases.

By the way, this pumping pipe 30 has a problem of reducing the water pressure of the ground water supplied.

Of course, conventionally, a structure is bent so that one side of the positive connection tube 30 is bent toward the bottom and the other side toward the side.

In addition, there is also shown a structure that facilitates the separation, coupling of the positive connection pipe 30 by the inclined surface.

However, in the prior art, such a positive connection tube 30 is separated and coupled by self weight, or by being separated and combined by a complex clamp, so that a rigid coupling is not achieved or a significant inconvenience in separating and joining operations. There was a following issue.

However, as described above, the structure of the connecting pipe coupling means 90 using the spirally coupled rotary bar 91 is easy to separate and couple the positive connection pipe 30, and a relatively strong coupling is achieved.

In the connection pipe coupling means 90 as described above, the configuration in which the inclined surface acts for separation and coupling of the positive connection pipe 30 may be applied in a modified manner as in the prior art.

However, as shown in FIG. 1, the first coupling plate 93, the second coupling plate 94, the support body 95, and the pressing body 96 may be implemented in the form of a rigid coupling, which is convenient and preferable. .

In the accompanying drawings, the first coupling plate 93 has a hole formed in the center portion, and an inclined surface is formed toward the outside in the vicinity of the edge, and is integrated with the flow path connecting pipe 80.

In addition, the second coupling plate 94 has a hole formed in the center portion, and an inclined surface is formed toward the outer side near the edge, and is integrated with the positive connecting pipe 30.

In addition, the support body 95 has a shape corresponding to the inclined surface formed in the lower portion of the second coupling plate 94 and has an inclined surface in which the inclined surface formed in the lower portion of the second coupling plate 94 is in contact with each other.

In addition, the pressing body 96 has a shape corresponding to the inclined surface formed on the upper portion of the second coupling plate 94 and has an inclined surface in contact with the inclined surface of the second coupling plate 94 when moved upwardly or downwardly. have.

Therefore, the pumping connector 30 is placed in a position for coupling, and the rotary rod 91 is rotated to move the pressurizing body 96 while pressing the second coupling plate 94. While holding the bond is made.

However, if only the spirally coupled rotary rods 91 are coupled to the pumping connection pipe 30 and the pumping pipe 80 and the pumping pipe 1, a problem occurs that the coupling force weakens over time, and consequently, Leakage leads to problems.

This is because the ground water is repeatedly supplied and stopped, and a fine shock (vibration) is generated in the pumping pipe (30) by the water pressure of the ground water, and this vibration is increased as the coupling force is weak, and eventually the groundwater leakage occurs.

Therefore, as shown in Figure 1 by the rotation of the rotary rod 91, the positive connection pipe 30 is prevented from loosening to prevent the rotary rod 91 from being released by the impact in the state connected to the flow path connecting pipe 80 and the pumping pipe (1) There is a need for further means 97.

The anti-loosening means 97 may be implemented in various forms to hold the rotary rod 91 so that no shaking occurs even when an impact due to the supply and stop of the ground water is generated in the pumping connection pipe 30.

However, as shown in FIG. 1, it is preferable to implement a form having an anti-loosening nut 97a that is tightened to be in close contact with an object in a fixed state while being coupled to the rotating rod 91 in a spiral manner.

The structure having a positive connecting pipe 30 and a connecting pipe coupling means 90 as shown in FIG. 1 is a structure in which two points of the positive connecting pipe 30 are connected by pressing one point of the positive connecting pipe 30. .

Therefore, the packing is installed while the coupling portion of the pumping pipe 1 and the pumping connector 30 is generally coupled, and the packing 82 is positioned at the coupling portion of the pumping pipe 80. Without evenly pressurized water leakage may occur due to strong water pressure.

In order to solve this problem, the pumping pipe fixing body 40 is spaced apart from the upper end of the pumping pipe 1 so as to be fixed to the pumping pipe 1 so that the upper end of the pumping pipe 1 protrudes into the facility installation space 11. And, the pumping pipe 30 is preferably so that the upper end of the pumping pipe (1) can be inserted for the connection.

At this time, the packing 32 is positioned between the outer side of the pumping pipe (1) and the pumping pipe (30).

Pumping connection pipe 30 is connected to the grounding water supply pipe (2) in a configuration in which one side is connected to the pumping pipe toward the lower side and the other side is bent toward the ground water supply pipe (2) It is preferable to further provide a rib 31 for connecting the vicinity of the vicinity and the vicinity connected to the pump pipe (1).

This is to prevent the deformation of the positive connector 30 is not generated due to the force applied at the same time the force applied to connect the positive connector 30 is smoothly transmitted to the two connection points.

Various components (e.g., flow connection pipes, etc.) in the installation space 11 to facilitate the operation of selectively connecting or separating the pumping pipe 30 to the pumping pipe 1 and the ground water supply pipe 2 as described above In the structure in which the connection pipe coupling means 90, the loosening prevention means 97, etc. are positioned, the upper part of the well 3 is blocked through the well coupling flange 70 and the positive pipe fixing body 40 as shown in FIG. It is desirable to.

In the case shown in Figure 1, after installing the protective case 10, the pumping pipe (1) is fixed, so that the various components located in the facility installation space (euro connection pipe, connecting pipe coupling means 90, anti-loosening means Significant difficulties arise in ensuring that (97, etc.) are in the correct position.

However, as shown in FIG. 6, when the pumping connection pipe 30 is seated on the pipe coupling flange 70, the protective case 10 is coupled to the pipe coupling flange 70 in a state where the installation of the pump pipe 1 is completed. This is how components can be naturally placed in the correct position.

That is, in the case as shown in Figure 6 (e.g., euro connection pipe, connecting pipe coupling means 90, loosening prevention means 97, etc.) is installed in the facility installation space 11, the pumping pipe (1) The protective case 10 is connected so that the pumping pipe 30 installed in the facility installation space 11 and the pumping pipe 1 installed in the pipe fitting flange 70 are connected without being affected. When it is seated on the coupling flange 70, various components (e.g., euro connection pipe, connection pipe coupling means 90, loosening prevention means 97, etc.) for separation and coupling of the amniotic fluid connection pipe 30 are set at the correct positions. will be.

In this state, when the protective case 10 and the pipe coupling flange 70 are connected by using a bolt or the like, various components such as a flow path connecting pipe 80, a connecting pipe coupling means 90, and an anti-loosening means 97 are provided. The fixing is completed so that there is no change in position.

In the protective case 10 of the present invention, when a pressure higher than the value set in the facility installation space 11 is generated, a vent hole 17 is formed so that the air in the facility installation space 11 is automatically discharged. A pressure control valve 18 connected to the hole 17 may be further provided.

That is, rainwater or sewage does not flow into the facility installation space 11, and when a high pressure is generated in the facility installation space 11, air is automatically discharged to the outside of the protective case 10 so that the facility installation space 11 is located within the facility installation space 11. To control the pressure.

In the present invention, the protective cover 20 may further include a lock 100 to restrict the separation from the protective case 10.

That is, if the lock 100 is not opened, the protective cover 20 is to be separated from the protective case 10.

This configuration is to prevent the groundwater contamination and damage to the wells due to management failure by preventing the person to open the protective cover 20, except the person concerned.

The pumping pipe fixing body 40 of the present invention is preferably provided with a connecting ring 110 capable of lifting the pumping pipe 1 by hanging a wire or a rope.

In other words, when there is a need to repair and replace the submersible motor or pumping pipe to hook the wire 110 or wire to the equipment such as a crane to lift the pumping pipe immediately from the well.

If the packing is not located between the protective case 10 and the pump pipe fixing body 40 of the present invention or there is no separate means, the installation space of the facility in the process of the rain or some rainwater introduced into the facility installation space 11 Even a small amount of liquid may fall into the groundwater source.

Therefore , in the structure as shown in FIG. 1, it is preferable to place the packing 16 between the protective case 10 and the pump tube fixing body 40. In the case of FIG. 6, the pipe fitting flange 70 and the pump tube fixing body ( It is preferable to place the packing 16 between 40).

As another method, foreign substances located at the bottom of the facility installation space 11 are introduced into the vicinity of the pump installation pipes 12 and 72 at the outside of the pump pipe insertion ports 12 and 72 of the facility installation space 11. There is a method of forming the projection 19 so as not to.

In the case of having such a projection 19, it is preferable to provide a cover plate 33 in the pumping connection pipe 30, so that the cover plate 33 covers the upper portion of the projection 19 when connected to the pumping pipe. .

Of course, the method of positioning the packing 16 and the method of forming the protrusions 19 may be performed in parallel as described above.

In the present invention, the measurement water supply pipe 130 and the measurement water supply pipe 130 through which the groundwater flows through the pump pipe so that the ground water via the pump pipe (1) can be selectively extracted from the facility installation space (11) Measured water discharge valve 140 connected to the facility installation space 11 may be provided.

According to such a structure, it is easy to test the contamination state of the groundwater through the pump pipe 1, etc.
