Description

PIPE CONNECTING STRUCTURE}

The present invention relates to a pipe structure that is piped in a right angle direction, and more particularly, pipes that are piped in a direction perpendicular to each other, for example, the discharge head and the water supply pipe by pressing the discharge head and the water supply pipe of the groundwater pumping device in the direction of gathering with each other. It is related to the pipe structure that can be connected more closely and the pipe joint in a right direction so that interference does not occur when lifting the pump pipe is installed.

Fluid, for example, groundwater, oil, gas, etc. is supplied to the place of use through the pipe, at this time, the two pipes can be piped in a right direction depending on the installation conditions, etc. In the following, the connection structure of the pipe using the groundwater as an example Will be described.

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 particular, one of the main culprits for accelerating the contamination of groundwater was the inflow of contaminants from the surface area into the groundwater wells without any resistance. In the meantime, the present inventors have developed a variety of inventions and inventions that can completely seal the upper part of the groundwater wells, while improving the functions of the components of the groundwater wells while at the same time fundamentally blocking the inflow of contaminants from the surface. Has developed and supplied products. In the field application process of the developed technology, the most difficult was the high pressure of the discharge port connected to the pumping pipe inside the sealed upper guard and the water inlet connected to the water supply pipe outside the sealed upper guard using a hand in a space of about 250mm diameter. Even in the strong leak was to combine. In Utility Model Registration No. 0369260 (Utility Model Registration Name; Combination Device of Discharge Port and Water Supply Port of Groundwater Core), Applicant uses the screw tightening method to press the wedge to the projection of the pump head to couple the discharge port to the water supply port. Succeeded in developing it. However, this invention has a difficulty in installing the water meter in the vertical direction. In addition, the present applicant invented a closed upper protection hole in which a pocket was formed through patent application No. 10-2005-0076696 (patent name; groundwater deep-sealed upper protection device in which a water pipe pocket was formed) to move the water meter in a horizontal direction. While succeeding in developing a product that can be combined with the piping configuration while securing a space for installation, in this case, the connection of the pipe is based on the mating surface of the outlet and the water inlet during the joining process by adopting the cam lock coupling (aka hose coupling) method. Therefore, when joining or disengaging, more than 20mm of forward and backward separation distance is required. Therefore, the upper part of the positive pipe must use a corrugated pipe to help flexion for free forward and backward of the discharge port. The internal size of the upper guard must be enlarged and consequently the installation space of the device is increased. The only problem with the device component that has increased by an issue with the inconvenience of manageability

there was.

On the other hand, geothermal [地 熱; geothermy] refers to the amount of heat released from the inside of the earth to the outside through the surface. Geothermal heat is emitted from the entire surface of the earth to the outside. Higher value in the zone. The outflow methods are based on heat conduction, gas, hot water and volcanic eruptions. Geothermal energy is often used for power generation in places where there is a large amount of crustal heat, such as New Zealand, Italy and Japan. Geothermal heat is also based on the thermal energy generated by the natural decay of radioactive materials in the earth's crust. On the other hand, heat is hardly released to the surface because the mantle is thermally insulated in the hot earth, where iron and nickel are melted. Appropriate use of the geothermal heat is quite advantageous in terms of environment. There are no carbon dioxide emissions and few pollutants. And geothermal heat can be used in many forms, including direct heating, power generation, heating and cooling through heat pumps, and heat for manufacturing.

In the geothermal heat exchange technology as described above, the above-described sealed upper protection hole is applied, and thus has the problems described above.

In order to solve such a problem, there is a conventional technique to tightly connect the water supply pipe and the water supply pipe by the yoke method, but this requires an excessive length in the horizontal length direction, thereby increasing the size of the sealed upper protection hole and thus wider installation. There is a problem that the area is required.

The present invention for solving the problems described above, by connecting the discharge portion for pumping the ground water discharged in a watertight direction to prevent the leakage of groundwater, and to increase the binding force while simplifying the configuration for watertight discharge portion The purpose is to provide a pipe structure for the pipe joint.

In addition, another object of the present invention is to fix the discharge head to the pumping pipe, so as not to interfere the configuration of the discharge head and the water supply pipe when lifting the pumping pipe for the maintenance of the heart pump installed in the pumping pipe.

In order to achieve the above object, the pipe structure is piped in a right angle direction according to the present invention, the first pipe connected to the upper end of the pump (discharge head), the second pipe connected to the discharge side of the first pipe (water supply pipe ), Characterized in that it comprises a yoke and a pressure rod for moving the first and second pipes in the tightening direction.

In addition, the present invention is characterized in that the yoke is hinged to the second pipe is disposed to be inclined with respect to the first pipe to pipe the first and second pipes.

As described above, according to the pipe structure of the pipe joint in the perpendicular direction according to the present invention, the first and second pipes can be tightly connected by tightening in the joint direction with the first and second pipes supported from both sides. Leakage of the groundwater can be prevented, and the length of the discharge head or the like does not have to be excessively long.

In addition, when the yoke moves to the first or second pipe or rotates to the water supply side, the interference is not generated when the pump pump and the discharge head serving as the first pipe are lifted together so that the air can be cut off. have.

≪ Example 1 >

As shown in Fig. 1 and Fig. 2, the pipe structure that is piped in the perpendicular direction according to the present embodiment is a second pipe at the bottom of the discharge head 10, which is the first pipe piped to the upper end of the pump pipe (1) By fitting the phosphorus water supply pipe 20 in a right angle direction, it is comprised from the yoke 30 and the pressure rod 40. As shown in FIG. Here, the discharge head 10 and the water supply pipe 20 are merely examples for clarity, and the discharge head 10 and the water supply pipe 20 are meant to represent pipes, respectively.

The yoke 30 is formed on the horizontal portion 31 and the leg portion 32 and the leg portion 32 extending downward from the left and right sides of the horizontal portion 31, respectively, to support the water supply pipe 20 ( 33). As shown in FIG. 3, the leg part 32 has a length covering the pipe joint of the discharge head 10 and the water supply pipe 20. The support jaw 33 is formed to protrude in the direction facing from the lower end portion 32, for example, and is supported by the bottom of the outward flange 21 formed at the upper end of the water supply pipe 20. In order to increase the binding force between the support jaw 33 and the flange 21, as shown in the arc of FIG. 3, the support jaw 33 and the flange 21 are formed with key projections 21a and 33a protruding in opposite directions. Can be.

The pressurizing rod 40 is installed on the yoke 30 so as to be lifted and lowered to support the discharge head 10 toward the water supply pipe 20. The pressure bar 40 is capable of any structure capable of supporting the discharge head 10 by pressing and is preferably screwed. The lower end of the pressure bar 40 (see FIG. 3) is provided with a pressure plate 41. The pressure plate 41 is preferably configured through a bearing or the like so that the pressure bar 40 does not rotate even when the pressure rod 40 rotates.

According to this structure, the discharge head 10 and the water supply pipe 20 are tightened with each other by the pressure bar 40 and the support jaw 33 so that they can be tightly connected therebetween.

As shown in Fig. 1, the discharge head 10 is located on the surface side of a casing (which may be composed of an upper casing 2 on the ground surface side and a lower casing 3 inserted into the ground to protect the pumping pipe 1). It is inserted and protected inside the upper casing 2, and the water passage 11 (see Fig. 4) is provided therein. The channel 11 secures the moving distance of the yoke 30 by turning in the lateral direction with respect to the direction of the pumping pipe 1, which will be described in detail later. The inlet portion 11a and the discharge portion 11b of the water passage 11 are respectively opened toward the lower side and have different heights (for example, the inlet portion 11a is lower than the discharge portion 11b) when viewed from the side. It may be made of.

The present invention yoke 30 (pressurizing rod 40 is a yoke (so as to facilitate the lifting of the assembly of the pump 1 and the discharge head 10) during maintenance of the cardiac pump (not shown) installed in the pump (1) 30) is naturally installed so as to be movable together with the yoke 30).

The yoke 30 may move toward the discharge head 10 side and the water supply pipe 20 side so that the lifting pipe 1 may be easily lifted. That is, when the yoke 30 is tightened with the discharge head 10 and the water supply pipe 20, the lifting pipe 1 cannot be lifted, and the yoke 30 is removed from the tightening part of the discharge head 10 and the water supply pipe 20. When spaced apart (moving to the discharge head 10 side or the water supply pipe 20 side), the restraint force between the discharge head 10 and the water supply pipe 20 is lost, so that the lifting pipe 1 can be lifted.

As a structure for this purpose, for example, as shown in Figs. 1 and 5, the yoke rail 12 is formed on the outer wall of the discharge head (10). The yoke rail 12 guides the movement of the yoke 30 by allowing the support jaw 31 of the yoke 30 to slide. Here, as described above, the length of the water passage 11 of the discharge head 10 is increased to secure the moving distance of the yoke 30 so that the yoke 30 can be freely moved.

Alternatively, as shown in FIG. 6, the yoke receiving portion 22 in which the yoke 30 is accommodated is formed at the end of the water supply pipe 20 so that the yoke 30 moves to the yoke receiving portion 22. The yoke accommodating part 22 may be formed to protrude upward from one side of the water supply pipe 20 and the support jaw 33 may be supported at the bottom.

As shown in FIG. 1, the center retaining groove 23 is formed in the flange 21 of the water supply pipe 20 so that the discharge head 10 and the water supply pipe 20 coincide with the center at the core. A center holding protrusion 13 is formed at the bottom of the discharge side, and the center holding protrusion 13 is fitted into the center holding groove 23.

Alternatively, as shown in FIG. 7, a center holding rail 2a is formed in the inner wall of the upper casing 2 in the vertical direction, and a center holding guide 14 is formed at the circumference of the discharge head 10, thereby providing a center holding guide. (14) is placed along the center holding rail (2a) in the center of the installation and sentiment.

The water supply pipe 20 may be connected to, for example, a 45 ° elbow so that the pipe joint is easy and the length of the discharge head 10 is minimized while maintaining the depth of the pipe joint.

Up to now, although the yoke 30 is shown and described only as being vertical, the yoke 30 may be arranged to be inclined.

According to the piping structure that is piped in the right angle direction according to the present embodiment configured as described above, the pumping pipe 1 connected to the discharge head 10 is inserted into the core and the discharge portion of the discharge head 10 and the water supply pipe 20 are connected. Coffin

The yoke 30 is inserted into the pipe joint of the discharge head 10 and the water supply pipe 20, and the support jaw 33 is inserted to support the bottom of the flange 21. When the key protrusions 21a and 33a are applied, the key protrusions 21a and 33a are combined. When the tool is connected to the pressure bar 40 and turned in one direction, the pressure bar 40 rotates and descends to press and support the discharge head 10 toward the water supply pipe 20. At this time, the flange 21 of the water supply pipe 20 is supported by the support jaw 33 of the yoke 30, so that the discharge head 10 and the water supply pipe 20 are tightly joined together.

Meanwhile, the yoke 30 is moved to the yoke rail 12 of the discharge head 10 or the yoke accommodating part 22 of the water supply pipe 20 when repairing or replacing the cardiac pump installed in the pumping pipe 1. . In the former case, the yoke 30 is supported only on the discharge head 10 so that the yoke 30-the discharge head 10-the pumping pipe 1 are lifted together when the lifting is carried out. ) Is supported only when the discharge head 10-pumping pipe (1) is lifted together. That is, when lifting the heart pump, the heart pump can be lifted without separating the yoke 30 separately.

<Example 2>

As shown in FIG. 8, the pipe structure of the pipe joint in the perpendicular direction according to the present embodiment is formed such that the discharge head 10, which is the first pipe, is inclined downward toward the discharge portion, and the pressing surface 15 is formed at the circumference of the inclined surface. Is provided, the yoke 30 is rotatably connected to the water supply pipe 20 which is the second pipe via the hinge portion 34 is the hinge (34).

That is, when the discharge head 10 and the water supply pipe 20 are connected, the horizontal portion 31 of the yoke 30 is tightened through the pressure rod 40 while being inclined so as to correspond to the pressure surface 15 side. When the leg 32 of the yoke 30 is connected to the water supply pipe 20 by the hinge 35, the rotation is possible but is fixed, and thus the discharge head 10 between the pressure rod 40 and the hinge 35. And the water supply pipe 20 are hermetically joined.

In addition, when the cardiac pump is separated, the yoke 30 is rotated like an imaginary line to prevent interference with the discharge head 10, and then the discharge head 10 and the pump pipe 1 are separated.
