The present invention relates to a discharge port forward coupling device of the groundwater deep-sealed top protection hole, and more particularly, characterized in that the device is coupled by forward pressing the water supply port to the discharge port using the worm gear and worm wheel gear. After completion of installation, it is possible to combine the discharge port and the water inlet without leakage while maintaining the inner diameter of the out casing of the groundwater core, and it is easy to assemble and dismantle while being a closed structure, which can greatly improve the quality and reliability of the product. I would have to.

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, an upper protection facility with the periphery of the groundwater higher than the ground was installed to block the inflow of contaminated surface water or to install a cover device to prevent the contaminated material from entering the groundwater well. .

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 invention and improved utility model of various devices in which the groundwater well 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 being put into practical use.

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

In other words, it is important to closely shield the groundwater deep well cover and the outcasing inserted into the ground and drawn out to the top of the ground in order to completely seal the inside and outside of the deep well with the ground water well cover device. Depending on the combination, the size and structure of the upper protective manhole can be determined, which 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 addition, in the process of installing the sealed heart 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, the input of heavy equipment such as a fork crane is absolutely necessary, and a lot of manpower is required, which causes a problem of costly installation of the upper protector. 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, the inner diameter of the outcasing is reduced in the process of manufacturing the structure in a hermetic type, which causes a serious problem that the workability is seriously detracted from the lifting and reinstallation of the groundwater well pump and the pumping pipe. The combination of the discharge port and the water inlet is simply pressed by the weight of the cardiac pump and the positive pipe to prevent leakage, so that there is a high risk of leakage when high water pressure is formed.

In addition, in the case of small and medium diameter groundwater wells, a pumping pump is usually installed in the ground and a jet device is installed in the core to form a pumping pipe. A conventional airtight cover device maintains the same level as the ground surface and discharges from the discharge of the groundwater core. There was a problem such as not being able to connect the water inlet.

In addition, the present inventors invented and devised a discharge port forward coupling device of the groundwater core well-sealed upper protection hole as Patent Application No. 10-2004-0047325 and Utility Model Registration Application No. 20-2004-0019357 to solve the above problems However, if the forward tightening device is configured through mechanical combinations and functions without using air cylinders or hydraulic cylinders, the pump head is fixed at the support base by simply using a conical rod, a tightening nut, and a tightening bolt. It can be seen that there is a frictional force that requires a considerable amount of force to move forward by sliding, and it is found that an advanced structure of the forwarding device that allows the positive head to slide forward with a small rotational force from the outside is required.

The present invention to solve the above problems of the prior art,

By using the worm gear and the worm wheel gear, the outlet and the water inlet can be tightly combined inside the upper protection hole. In addition to being possible, it is possible to improve the quality and reliability of the product by being able to facilitate the assembly and disassembly while still being a sealed structure. After separating the coupling state and lifting the pumping head, the fixed base and the pumping pipe can be easily lifted inside the groundwater well, and the coupling fixing position is determined through the fitting protrusion and the support groove when recombining. Not only is it easy to maintain, 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, the quality and reliability of the product can be improved. The purpose is to provide a hermetically sealed groundwater well cover device.

In particular, by combining the worm gear, the worm wheel gear, the rotary cam, or the square rake gear or the bolt bar in the forward device, the pump head can easily move forward even with a small driving force in the fixed bearing part. There is also a purpose.

The present invention to achieve this purpose,

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this purpose are as follows.

The discharge port forward coupling device of the groundwater well-sealed upper protection hole applied to the present invention is configured as shown in FIGS. 2 to 11.

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 invent the discharge port forward coupling device of the groundwater heart well closed upper protection hole used in the groundwater heart well to collect ground water.

That is, reference numeral 1 denotes an upper protective casing, which is fixed by welding or flange coupling to the out casing of the groundwater core. On the inner circumference of the upper protective hole casing (1) is fixed by welding the lower disc ring (4). The lower disc ring 4 has a thickness of about 20 millimeters and its diameter is set to be smaller than about 10 millimeters than the diameter of the existing upper protective ball casing (1) to form a circular locking jaw. Of course, when the diameter of the upper protective ball casing (1) is connected to the outer casing, the diameter is reduced immediately connected to the lower disc ring (4) is fixed to the upper end of the small casing to be closed do.

On the inner circumferential surface of the upper protective ball casing (1) facing the lower disc ring (4), the alignment protrusions (5) were installed symmetrically on the opposite surface in the vertical direction.

Thereafter, the fixed support part 16 processed by the support recess recess 11 on both sides is installed on the lower disc ring 4 so that the alignment protrusion 5 can be used as a guide.

The fixed support portion 16 can be installed so that the vertical center lines of the water supply port 3 and the discharge port 21 coincide with the fitting protrusion 5 and the support recess recess 11. The fixed support 16 cuts the center of the pump head 21 at intervals slightly larger than the outer diameter of the pump head 21 so as to position the pump head 21 at the center of the fixed support 16 to secure the space of the opening 39. Will be configured. In this case, the sliding head 21 is fixed to the pumping head 21 so as to slide along the opening 39 space.

In addition, the water level measuring tube 35 is inserted into the fixed support portion 16 and the water level measuring tube hole 7 for drawing out to the upper portion, the power cable 37 for transmitting power to the cardiac pump, and the water level installed for detecting the water level. The power line hole 30 for installing the sensing line 38 is machined. Of course, when the pumping pipe 36 uses a weak material such as a plastic pipe instead of a steel pipe, the pump may support a weight of the cardiac pump and additionally configure a hole for installing a lifting rope used for lifting installation.

Here, the fixing base 16 will be able to be modified in various forms while maintaining its function. It is possible to withstand the load of the pumping pipe 50 and the cardiac pump, while fixing the flat iron having two sufficient thicknesses in a parallel position so that the forward device 9 can be constructed so that it can be spread over the lower disc ring 4. It may be. Of course, at this time, since the open area between the upper and lower parts can be widened, it is not necessary to process the separate water level measuring tube hole 7 or the power line hole 30, but the fitting protrusion 5 installed on the inner surface of the upper protective ball casing 1 is provided. The configuration of the supporting recess 11 to be adapted to the required configuration requirements. Only the projections 5 installed on the inner surface of the upper protective ball casing 1 may be closed in the form of a symmetrical projection in a position close to the lower disc ring 4 so as to be fitted to the support groove 11.

The bolt holder was machined in the fixed support 16 so that the forward device 9 could be bolted. Of course, it is possible to fix the nut or weld on the bottom of the machined hole or machined hole.

[First Embodiment]

Advancing device (9) is composed of a gear box-shaped body with a built-in gear is bolted or welded to the fixed support (16). The worm gear 53 is fixedly installed on the worm gear shaft in the forward device 9, and is engaged with the worm gear 53 so that the worm wheel gear 54 can rotate. The rotary cam 15 is integral with the worm wheel gear 54 or the shaft hole 19 is machined in the worm wheel gear 54, and the rotary shaft 17 extending from the rotary cam 15 is worm wheel gear 54. Inserted into the shaft hole of the worm wheel gear 54 so that the rotational force can be transmitted to the rotary cam 15 as it is. Of course, the shaft hole 19 may be configured by machining a square hole or by processing a key groove in a circular hole. The rotary cam 15 is not connected to the worm wheel gear 54 and the rotation axis 17 in the center of the concentric circle, but has an eccentric rotation center. That is, the rotary cam 15 has a shaft hole 19 configured to insert a key into a key groove coupled to the worm wheel gear 54 at an eccentric center, or a rotation shaft 17 formed of a square rotating rod of the worm wheel gear 54. By coupling to the center, one side of the specified circumferential surface of the rotary cam 15 in rotation of the worm wheel gear 54 can be obtained from the closest to the farthest distance from the center of the worm wheel gear 54. It was. As a result, the same effect may be obtained through the combination of the worm wheel gears 54 rather than the worm gear 53 to obtain the same effect as a result. In the first embodiment, the pressing surface is moved while the rotary cam 15 rotates in the vertical direction, but the pressing surface may be moved while rotating the rotary cam 15 in the horizontal direction. However, at any time in the vertical or horizontal direction, the pressing surface and the virtual line extending from the center of the rotation axis 17 of the rotary cam 15 are always arranged at right angles. As a result, even if a force pushing back to the pumping head 21 is prevented that the rotation cam 15 is rotated by the reverse rotation to prevent the leakage occurs in the coupling portion.

In addition, the compression spring is inserted between the discharge port 21 and the water supply port 3 so that the water supply port 3 and the discharge port 21 can be easily separated when the pressing surface of the rotary cam 15 is reversed.

In addition, the rear surface of the pumping head 21 is configured to have a rectangular horizontal surface, but the press-in protrusions 33 are formed at a height that can be in contact with the pressing surface of the rotary cam 15 of the forward device 9.

Second Embodiment

Advancement device 9 is composed of a gear box-shaped body with a built-in gear is bolted or welded to the fixed base 16. The worm gear 53 is installed in the forward gear 9 to be integrally fixed to the rotary shaft 17 and engaged with the worm gear 53 so that the worm wheel gear 54 can rotate. The pinion gear 23 is coupled to the worm wheel gear 54, but the pinion gear 23 is integrated with the worm wheel gear 54 so that the rotational force of the worm wheel gear 54 is applied to the pinion gear 23. To be delivered as is. When the worm wheel gear 54 is rotated by the rotation of the worm gear 53, this rotation force is transmitted to the pinion gear 23 as it is, and the pinion gear 23 is capable of horizontal movement of a pair of squares. Pushing or pulling the square rectangular gear 24 is to be moved horizontally. At this time, one end of the rectangular square gear 24 is fixed to the back of the center of the discharge port 20 of the pump head 21, when the rectangular square gear 24 is moved forward, the discharge port 20 is the water supply port (3) When moving to the) side and giving strong rotational force to the worm gear 53, the gear ratio is about 1/30, and the reduction ratio is formed in the pinion gear 23 gear and the square gear 24 again. By this arrangement, the discharge port 20 and the water supply port 3 can be combined without leaking by a strong pressing force.

Third Embodiment

Advancing device (9) is composed of a gear box-shaped body with a built-in gear is bolted or welded to the fixed support (16). In the forward gear 9, the worm gear 53 is fixedly installed on the rotating shaft, and is engaged with the worm gear 53 so that the worm wheel gear 54 can rotate. The worm wheel gear 54 is integrally coupled with the bolt bar 26 to the rotation shaft 17, and a female threaded rod 27 having a cylindrical shape in which a thread can be inserted when the bolt bar 26 is rotated is pumped head ( 21). When the worm gear 53 is rotated, the worm wheel gear 54 is rotated according to the reduction ratio, and the rotation force rotates the bolt bar 26 as it is. Of course, at this time, compared to the number of revolutions of the worm gear (53) maintains a very low number of revolutions by the reduction ratio, while the magnitude of the force to rotate the bolt bar 26 pushes the female threaded rod (27) Advanced. This forward force is to act as a coupling force of the discharge port 20 and the water supply port (3) as it is. At this time, the force generated on the opposite side is transmitted to the bolt bar 26, the worm wheel gear 54, and the rotating shaft 17 by maintaining sufficient strength in the process of fixing the gear box 14 to the gear box ( 14) The function of the device is not impaired by the pressing force transmitted to the body.

To drive the worm gear 53 for the lifting and installation of the groundwater well pump, open the lid 32 of the upper protective ball casing 1 and extend the opening and closing rotary handle 29 to the worm gear 53 to the outside. The pulled hex bolt head 14 was fitted with a box 22 fixed below the extension 28 so as to be rotated.

Of course, the reduction gear is built in the shaft of the worm gear 53 and may be configured by connecting a general geared motor operated by electric power. In this case, appropriate rotational force can be controlled by sensors such as load cells.

In addition, the water inlet (3) is inserted into the sliding ring 18 in the pumping head 21 at a height determined so that the discharge port 20 and the vertical horizontal center line can be forward and backward.

The tip of the water inlet 3 of the pumping head 21 is processed into a conical shape and allows the insertion of 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 to do.

Referring to the operation of the discharge port forward coupling device of the present invention ground water heart well closed upper protection hole configured as described above are as follows.

When the pumping pipe 36 of the pumping head 21 is bolted or screwed to the existing pumping pipe and installed in the groundwater core, the fitting protrusion 5 and the fixed support part of the upper protective ball casing 1 are installed. According to the support recess 11 of the 16, the alignment protrusion 5 of the lower disc ring 4 and the alignment protrusion recess 6 of the fixed support 16 are matched to each other, and the discharge port 20 in the vertical direction is formed. ) Coincides with the center of the water inlet 3. In addition, since the fixed ring portion 16 and the sliding ring 18 of the pumping head 21 are fixed or adjusted according to the height already irradiated, the horizontal centers of the discharge port 20 and the water supply port 3 also match. Will be in a state. Since the state where the center of the vertical direction and the horizontal direction of the discharge port 20 and the water supply port 3 coincide with each other has already been confirmed in a fixed or adjusted state, in order to drive the worm gear 53 in the forward device 9, Open the lid of the protective ball casing (1) and extend the opening and closing rotary handle 29 to the worm gear 53, the box 22 is fixed to the hexagonal bolt head 13, which is drawn out to the outside under the extension 28 In the first embodiment, the rotary cam 15 rotates while the circumferential surface distant from the rotary shaft 17 is pushed forward by pushing the pump head 21 due to the reason for fixing the rotary shaft 17 so as to be eccentric. (20) and the water supply (3) will be able to strongly combine. In addition, in the case of using the pinion gear 23 as in the case of the second embodiment, the worm wheel 54 is rotated by the drive of the worm gear 53 and connected to the same rotation shaft 17 as the worm wheel gear 54. The pinion gear 23 rotates, and the pump head 21 and the quadrangular square gear 24 fixed are pushed strongly against the water supply port 3 by pressing the discharge port 20 toward the water supply port 3 so that a strong water tightness is achieved even at high water pressure. You can lose.

In the third embodiment, when the worm gear 53 is rotated, the worm wheel gear 54 is rotated according to the reduction ratio, and the rotational force rotates the bolt bar 26 coupled to the worm wheel gear 54. Of course, at this time, compared to the rotational speed of the worm gear 53 is maintained by a very low rotational speed by the reduction ratio, while the magnitude of the force for the rotation becomes larger. In addition, since the part of the bolt bar 26 is already inserted into the female threaded rod 27 in the fixed position, the rotation of the bolt bar 26 immediately pushes the female threaded rod 27 forward. Let's go. This forward force is acted as a coupling force of the discharge port 20 and the water supply port 3 as it is, if you want to separate the discharge port 20 and the water supply port 3, the rotary handle for rotating the worm gear 53 You can reverse (29).

At this time, since the centers of the vertical direction and the horizontal direction of the discharge port 20 and the water supply port 3 coincide with each other, when the forced press-fitting is performed, the sealing property is ensured by the O-ring 34 installed in the discharge port 20. It is possible to supply water without leakage even under high operating pressure. Reference numeral 33 is a water level cap.

As described above in detail the present invention,

It is possible to easily change the structure of the upper protective air facility without reducing or changing the inner diameter of the existing groundwater core well, and the installation of the groundwater core well can be completed even in a small area. As the internal effective diameter is narrowed, it is difficult to adjust the construction period by installing the internal well materials before installing the closed upper protection hole, while the present invention maintains the effective diameter even after the upper protection hole casing is maintained. It is very convenient to be able to install materials. In addition, it is possible to obtain the effect of reducing the size of the upper protection engineering facilities, as well as to reduce the manpower and time by making it easy to install and lift in the depths of the lower surface of the ground, which is the quality of the product It is a very useful invention that can greatly improve the reliability.
