The present invention relates to an outlet and a water inlet coupling device of the groundwater core well, and more particularly, is characterized in that the device is provided by the forward press the water outlet is coupled to the discharge port, characterized in that, after completion of the installation of the outer casing core diameter It is possible to combine the discharge port and the water inlet without leaking while maintaining the same, and to improve the quality and reliability of the product by being able to easily assemble and dismantle while being a sealed structure.

As is well known, groundwater refers to water that fills or flows through gaps between underground strata and rocks, and in recent years, various pollutants are mixed with groundwater to deteriorate the quality of groundwater.

In order to solve the above problems, conventionally, by installing an upper protection facility in which the periphery of the groundwater is higher than the ground, it blocks the inflow of contaminated surface water or installs a cover device to prevent the contaminated material from entering the groundwater core.                         

However, the groundwater core cover device remains open, so in the case of normal habitats such as insects or floods, contaminated surface water flows into the groundwater core without any resistance, which inevitably results in serious groundwater contamination. It was in condition.

Accordingly, in order to improve the problems of the conventional open groundwater well cover device, the present invention provides an improved utility model and an invention of various devices in which the groundwater true cover device is hermetically sealed so that the pollutant does not flow from the top of the groundwater well well. Has filed and registered and is currently in commercial use.

However, the conventional hermetic groundwater core cover device has the effect of completely sealing the inside and outside of the heart well, the following problems occurred.

That is, in order to completely seal the inside and outside of the heart well with the ground water well cover device, it is important to closely shield the ground water core well closed cover and the out casing inserted into the ground and drawn out to the top of the ground surface. Depending on the size and structure of the upper protective manhole can be determined, this is also an important factor.

In more detail, in the related art, a problem arises in that a check valve, a water meter, and a shut-off valve that are sequentially connected by a pump pipe on an upper part of a hermetic heart cover cannot be configured together with a body such as a hermetic heart cover.

In the process of installing the sealed heart well cover, various measures to reduce the installation cost of the upper protector installed to protect the sealed cover from external influences have been studied together. In order to meet, it is necessary to input heavy equipment such as a fork-lane and a lot of manpower is required, resulting in a high cost of installing the upper protection. This was the reason why the ground water law was revised so that the condition of the upper guard could be set freely when the sealed heart cover was installed.

In addition, conventionally, when lifting the groundwater core pump, the pumping pipe installed on the ground is also separated, and a high cost is required due to the reason that a professional plumbing technician is required in the separation and recombination process. Occurred.

In addition, in the case of some devices to reduce the inner diameter of the out casing in the process of manufacturing the structure to the closed type, this causes a problem that the workability in lifting and re-installation of the groundwater well pump and pumping pipes.

In addition, in the case of a small-sized diameter groundwater well, a pumping pump is usually installed in the ground and a jet device is installed in the core to form a pumping pipe. The conventional airtight cover device maintains the same level as the surface of the ground and discharges and feeds the groundwater core. There were problems such as the inability to connect spheres.

The present invention to solve all the problems of the prior art as described above

By allowing the water discharge port and the water inlet of the sealed groundwater core to be watertightly coupled inside the upper protection hole, after completion of the installation, the water discharge port and the water outlet can be combined without leaking while maintaining the inner diameter of the out casing of the ground water core. It is a hermetic structure, which makes it easy to assemble and dismantle so that the quality and reliability of the product can be improved. If the lifting head is lifted after separating the coupling state, the upper disc and the pumping pipe can be easily lifted from inside the hot core, as well as the fixed fixing position is determined through the fitting protrusion and the sliding rail at the time of recombination. Not only easy, but also the size and shape of the upper guard can be made smaller or simpler, so that economical construction and maintenance can be achieved, and as a result, it is possible to improve the quality and reliability of the product. The purpose is to provide a groundwater well cover.

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, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

First, a feature of the technical configuration of the present invention is to improve the invention of the combination of the discharge port and the water supply port of the groundwater core wells used in the groundwater wells to collect ground water.

That is, reference numeral 1 is an out casing, and the lower disc ring 4 is welded and fixed to the upper end of the out casing 1, and the water supply case 2 is welded and fixed along the outer circumference of the lower disc ring 4. . Of course, the combination of the outer casing (1) and the lower disc ring (4) welds the flange that can be bolted to the upper portion of the outer casing (1) separately to adjust the height, and the outer casing under the lower disc ring (4) After welding the pipe with the same outer diameter as in (1), the packing can be inserted in the state where the flange is welded and fixed to the bottom of the flange. The lower disc ring (4) is configured to have two or more trapezoid-shaped alignment protrusions (5) on the upper surface of the lower disc ring (4). Also in this case, the shape of the alignment protrusion 5 may be hemispherical or triangular. The water supply case 2 fixed to the upper outer periphery of the lower disc ring 4 is welded and fixed to the water supply port 3 and the air breathing port 24 installed through the inner and outer parts. The inner surface of the water inlet is configured to have a well-finished conical inner surface.

In addition, the present invention is to install the upper disk 16 configured to be seated on the lower disk ring 4, the inner surface of the water inlet case (2) as a guide function. The inner surface of the water inlet case 2 may be configured to process the guide groove 27 on the outer circumference of the upper disc 16 so as to supplement the guide function, and to configure the guide rail 25 on the inner circumferential surface of the water inlet case 2. The bottom surface of the upper disc 16 is provided with a recess 6 for the fitting protrusion to be matched with the fitting protrusion 5 formed on the lower disc ring 4. Checking the position of the water supply port and inserting the upper disc 16 along the guide rail 25 on the inner circumferential surface of the water inlet case (2), the alignment protrusion (5) and the upper disc 16 configured on the lower disc ring (4) accurately The pairing is made so that the vertical center line of the water supply port 3 and the discharge port is coincident. The upper disc 16 cuts in the center direction at intervals slightly larger than the outer diameter of the pump head 21 so that the pump head 21 can be positioned at the center of the upper disc 16 to secure the space of the opening 29 and the cut surface. 30 is configured by welding the sliding rails 17 on both upper surfaces. Of course, the sliding rail 17 may use the upper surface of the upper disc 16 as it is, and can be configured to operate the jaw for sliding on the pumping head 21.                     

In addition, the upper disk 16 is inserted into the water level measuring tube hole 7 for drawing the water level measuring tube to the upper part and the power line hole 8 for transmitting power to the water well pump and installing the water level wire. Of course, if the pump is made of a weak material such as a pipe, not a steel pipe, it can support the weight of the cardiac pump and additionally constitute a hole for installing a lifting rope used for lifting installation.

The forward tightening device 9 is formed on the surface opposite the opening 29 of the upper disc 16.

The forward tightening device 9 is composed of a thick rectangular body with one side open, and is fixed to the upper disk 16 by welding, and a tightening nut is fixed to the upper surface thereof. The bracing plate 10 is fixed to the rear surface and the bracing protrusions 11 are formed at the height of the bracing plate 10, that is, coincident with the vertical horizontal center line of the water supply port 3 and the discharge port 20.

Inside the forward tightening device (9) is a conical indentation rod (12) is connected to the tightening bolts 13 and fixed so that only up and down movement irrespective of the rotation of the tightening bolts (13). The upper end of the tightening bolt 13 constitutes a hexagonal bolt head 14. Of course, the forward tightening device 9 may use a pressurized cylinder using hydraulic pressure or pneumatic pressure without using a pressurized rod, and a press-fit bolt for supporting the body or the support plate 10 of the forward tightening device 9. By such a configuration that the forward head can be moved forward and backward in accordance with the center line, such as to enable the reverse may be used in various ways. The press-fit rod 12 may also be configured to be conical or processed into a thick triangular iron piece so that its cutting cross section decreases toward the downward direction.

In addition, the opening 29 of the upper disc 16 is configured to be able to fix the departure prevention plate 28 in order to prevent the fall off during the installation and lifting process of the pumping head 21 is configured to be detachable.

Pumping head 21 is manufactured in the form of a tee pipe through which the female thread is drilled through three directions, so that the upper surface of the pumping pipe 23 and the straight line is threaded so as to be connected to the pumping pipe 23 so as to allow emergency water supply. The emergency water supply port 31 was configured and the emergency water supply plug 32 was screwed together.

In addition, the rear surface of the pumping head 21 is configured to have a rectangular horizontal surface, but constitutes the indentation protrusion 33 at the same height as the support protrusion 11 of the forward tightening device (9).

In addition, the water inlet 3 is provided with a sliding plate 18 on the side of the pump head 21 at a height determined so that the discharge port 20 and the vertical horizontal center line can be moved forward and backward, the sliding plate 18 The small height can be adjusted to configure the slide plate height adjustment bolt. Of course, the sliding plate 18 may be fixed to the pumping head 21 and may be formed by processing the jaw or groove on both sides of the pumping head 21. The tip of the water supply port 3 of the pumping head 21 forms an O-ring groove 22 for processing into a conical shape and inserting one or more O-rings 34.

On the other hand, the present invention may be variously modified and may take various forms in applying the above configuration.

And, it is to be understood that the invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood as

Referring to the operation of the discharge port and the water inlet coupling device of the present invention groundwater core well configured as described above are as follows.

After inserting the pumping head 21 into the upper disk 16, the separation prevention plate 28 is coupled to prevent the dropping of the upper disk 16. At this time, the forward tightening device 9 is in the form of supporting the pumping head 21 while the indentation rod 12 is in a retracted state so that the upper disc 16 is not excessively separated from the pumping head 21. When the pumping pipe 24 of the pumping head 21 is bolted or screwed to the existing pumping pipe and installed in the groundwater core, the guide rail 25 and the upper disc 16 of the water inlet case 2 are installed. According to the guide groove (27) of the lower disc ring (40) and the fitting protrusion (5) of the upper projection (16) for the alignment projection groove (6) is made to match the discharge port 20 and the water inlet in the vertical direction ( The center of 3) coincides with the discharge port 20 because the sliding rail 17 of the upper disc 16 and the sliding plate 18 of the pumping head 21 are fixed or adjusted according to the height that has already been irradiated. ) And the center of the horizontal direction of the water inlet 3 also coincide with each other, but if there is a slight error, the height adjusting bolt 26 is adjusted. In the state that the center of the direction and the horizontal direction coincide is already fixed or adjusted Since it has been confirmed, the tightening bolt 13 is rotated to descend the forward push rod 12 in the retracted state from the forward tightening device (9), and the push rod 12 is lowered forward. As the width of the structure becomes wider, the projection protrusion part 11 formed at the same height as the support projection part 11 and the support projection part 11 formed on the support plate 10 of the forward tightening device 9 ( A force widening between 33) acts and this force moves the pump head 21 toward the water inlet 3 of the water inlet case 2. Already, the outlet 20 and the water inlet 3 Since the centers of the vertical and horizontal directions coincide with each other, when the forced press-fitting is performed, the sealing is ensured by the O-ring 34 installed in the O-ring groove 22 of the discharge port 20, even under high operating pressure. It is possible to supply water without leakage.

Of course, in the case of a small medium diameter groundwater well, a pump pump is installed on the ground and a jet device for a deep well is constructed, so that a discharge pipe supplied to the jet device and a suction pipe connected to the pump side are simultaneously configured. It is possible to have two discharge ports and the coupling can be made on the same principle.

As described above in detail the present invention,

The structure of the upper protection facility can be easily changed without reducing or changing the inner diameter of the existing groundwater well, and the installation of the groundwater well can be completed even in a small area, thereby reducing the size of the upper protection facility. In addition to being able to easily install and lift in the depths below the ground, it is possible to save manpower and time, which is a very useful invention that can significantly improve the quality and reliability of the product.
