Description

The present invention relates to a deep well submersible motor pump protective pumping pipe, and more specifically, a deep well submersible motor capable of safely constructing a pumped pipe installed in a deep well and pumping stably by a submersible motor pump. It relates to pump protection pumping pipe.

Generally, in order to raise underground groundwater, hot spring water, etc. to the ground, after drilling a hole to a deep place in the formation, an underwater motor pump is inserted into the borehole to raise the water to the ground for drinking water. Effectively used in hot spring water or agricultural water.

If the technology for the development process of such deep well groundwater is briefly seen with reference to FIG. 1, the borehole H drilled using the drilling equipment is not drilled in a straight line but is drilled in an irregular direction. Therefore, the pump pipe P as well as the submersible motor pump M is installed against the rock wall or in contact with the rock wall. Therefore, the underwater motor pump collides with the borehole rock wall and is damaged and broken by the severe vibration generated while the submersible motor pump is operating. As a result, there is a problem in that the service life is shortened, and repair and repair costs are spent. Not only this, the pumping pipe is composed of a unit standard of 6M and is repeatedly connected by a predetermined connecting means, and an electric wire and a wire rope (hereinafter referred to as “underwater electric wire”) connected to the submersible motor pump are used. There is a problem that the risk of safety accidents such as disconnection, leakage, and electric shock is very high.

Here, Korean Patent No. 10-1053710 (registration date: July 27, 2011) which has been previously proposed by the same applicant (inventor) as the present invention to solve the above-mentioned problems. "Pumping prevention coupling of submersible motor pump" of No. 10 or "Pumping pipe coupling" of Korean Patent No. 10-1224331 (registration date: 03/07/2013) is known as the prior art (patent document) It has become. According to this, the pumped pipe and the submersible motor pump can be safely constructed by providing the pumped pipe with the pumped pipe guide means such as packing or couple ring.

However, the prior art as described above is loosened because the packing collides with the wall surface in the process of inserting or lifting the pump pipe into the borehole, or the vibration of the submersible motor pump and the submerged electric wire and wire are not fixed. There were problems such as easy separation and breakage. In the case of the above-described couple ring, the mold is formed by a guide formed on the outside of the main body having a recessed groove so that the underwater electric wire and the wire can be wound around the wing by casting from a predetermined mold (mold). After casting from the frame, it has to be cut separately, resulting in an increased number of work processes, high processing defects, high productivity, and low production costs.

According to the drawings, the present invention is for constructing a pumping pipe P connected to the first pipe P1 to which the submersible motor pump M is attached and the second to third... Nth pipes P2, P3. In the deep well submersible pump for the deep well submersible motor pump provided with the guide means, the first pipe P1 is divided into halves along the longitudinal direction so as to wrap the first pipe P1, and the first fixing part 14 is formed at the upper part and the lower part. The expansion part 12 is formed between the first fixing parts 14, and the packing 10 is formed with longitudinal incisions 16, 18 on the surface, and the packing 10 is pumped by being coupled to the first fixing part 14. And a clamp band 20 that is fixed to the pipe P. The vertical first and second guides 32 and 34 that are sandwiched between the first pipes P1 and are fixed to both ends of the packing 10 and formed on the outer surface are mutually connected. The wire E and the wire rope W pass through the space portion 35 provided between the first and second guides 32 and 34 by injection molding in an intermediate portion so as to intersect (staggered). The first coupling ring 30 is configured as described above.

The above will be described in more detail as follows.

The deep well submersible motor pump protection pumping pipe 100 according to the present invention includes a packing 10 coupled to the pumping pipe P, a clamp band 20, a first couple ring 30 and a second couple ring 30a, and a connecting pipe body 40. . In the pumping pipe P, the first pipe P1 to which the submersible motor pump M is attached and the second to third to nth pipes P2, P3,... Pn are assembled in the longitudinal direction by the second couple ring 30a and the connecting pipe body 40. Thus, various measuring instruments and valves are coupled with the upper end of the nth pipe Pn exposed to the ground. On the other hand, the submersible motor pump M sucks water by the high-speed rotational force of the submersible motor and the turbine and pumps the water to the ground by the pumping pipe P.

The packing 10 is selectively coupled to the water pipe P inserted into the borehole H, that is, the first pipe P1 and the second to third... Nth pipes P2, P3,. The submersible motor pump M attached to the lower end of the first pipe operates stably by mitigating and preventing damage to the pumped pipe. In this case, while the packing 10 is adhered from the upper end to the lower end of the pumping pipe P, the insertion is safely guided while sliding along the inner surface of the borehole H, and the pumping is performed while elastically contacting the inner surface of the borehole. A buffer space is formed between the pipes.

The packing 10 is a hollow cylindrical shape that is connected to the pumping pipe and wraps around, and is divided into halves along the longitudinal direction and is easily connected from both sides of the pumping pipe. Then, the first fixing part 14 is formed at the upper and lower parts and fixed to the clamp band 20, and the extension part 12 having the protruding ring 13 is formed between the first fixing parts 14. A buffer space is formed between them. The extension portion 12 is conical and has a diameter that is expanded as shown in the drawing, and one or a plurality of the extension portions 12 are provided at predetermined intervals, and a protruding ring 13 is formed in the middle of the extension portion.

According to the present invention, the packing 10 is fixed with the clamp band 20 by forming the second fixing portion 15 that is separated between the expansion portions 12 by separating the plurality of expansion portions 12 at a predetermined interval. It is comprised by this. That is, in the packing 10, the pair of extended portions 12 are spaced apart from each other at a predetermined interval, and the clamp band 20 is wound around the intermediate second fixing portion 15 formed therebetween to be firmly fixed to the first pipe P1.

As a result, the clamp band 20 is tightly wrapped around the first and second fixing portions 14 and 15 and is fixed or released depending on the direction in which the screw is tightened as a fixing means on which a fixing force acts so as not to be removed arbitrarily. It is configured to include a clamp or cable tie, a bundling band, etc.

Further, the packing 10 has longitudinal incisions 16 and 18 formed in the expansion part and the fixing part so that the diameter can be expanded or contracted elastically. It is easy to install the cable and prevent interference and damage.

On the other hand, the packing 10 is preferably formed of natural rubber, synthetic rubber, synthetic resin, urethane or the like having excellent impact water absorption and elasticity.

While the first couple ring 30 is sandwiched between the pumping pipes P, the clamp band is fixed again so as not to be loosened while being in close contact with both ends fixing portions of the packing. In this case, the first coupling ring 30 is fixed to the pipe by a connecting means such as welding. The

The first couple ring 30 is formed with a vertical first guide 32 and a second guide 34 on the outer surface to prevent contact and collision with the rock wall, and it is securely fixed by winding a wire and a wire rope around the band. And separation is prevented. The first guide 32 and the second guide 34 are spaced apart from each other at a predetermined interval. The first guide 32 and the second guide 34 are formed so as to intersect with each other in the circumferential direction (staggered). The electric wire E and the wire rope W pass through the space portion 35, and a bundle band (tie) or the like is wound and fixed firmly. In this case, the first couple ring 30 is formed so that the first and second guides cross each other, and can be mass-produced by casting using a mold (mold), and a separate cutting process is required. Productivity is excellent because it is not necessary. On the other hand, the first and second guides 32 and 34 are formed with 4 to 8 at the same interval according to the standard (diameter) of the pipe, and about 6 is most preferable.

In particular, according to the present invention, the first couple ring 30 is configured such that the protrusion 33 formed on the first guide 32 is fixed while sandwiching the outside of the clamp band 20. That is, the first coupling ring 30 is not loosened arbitrarily while the protrusion 33 formed on any one of the first guide 32 and the second guide 34 is hooked on the outside of the clamp band 20. And is safely protected from external impact force.

Further, according to the present invention, the vertical first and second guides 32 and 34 are attached to the upper ends of the first to n-th pipes P1. And the second coupling ring 30a in which the electric wire E and the wire rope W pass through the space 35 prepared between the first and second guides 32, 34, and the first to second The n-th pipe P1... Includes a connecting pipe body 40 attached to the lower end of the Pn and screw-connected to the second couple ring 30a. That is, the second couple ring 30a is prepared between the first and second guide rings 30a and 32 by forming the vertical first guide 32 and the second guide 34 so as to cross each other at a predetermined interval. As a result, the electric wire E and the wire rope W are entangled while passing through the space 35. From now on, the electric wire E and the wire rope W can be safely inserted into the borehole together with the pipe without loosening to prevent damage such as entanglement or twisting. Further, the first and second guides 32 and 34 are formed in a round streamline with no corners, and are guided so that the pumping pipe P advances into the borehole 100 in a circle.

Further, according to the present invention, the second couple ring 30a has a step 36 formed in an inner middle portion, and the first to nth pipes P1, P2,. The connecting tube 40 is screwed to the female screw 37 formed in the above. That is, the second couple ring 30a is attached to one end of the upper ends or lower ends of the first to n-th pipes P1,... Pn, and is coupled to the other end of the first to n-th pipes P1. The connected connecting tube body 40 is connected with a screw so that it can be easily connected on site. For this purpose, a female screw 37 is formed on the inner step 36 of the second couple ring 30a, and the lower screw 42 of the connecting tube 40 is assembled. In this case, the second couple ring 30a is joined to the groove 38 at the lower part of the step by the lower first pipe and joined by a joining means such as welding or a screw, and the connecting pipe body 40 is also connected to the upper groove part 44. Two pipes are connected by a connecting means.

Here, the first pipe P1 is screwed to 1 at the upper end connection of the submersible motor pump M by a connecting tube 40 attached to the lower end, and the upper end of the first pipe P1 is fixed by sandwiching the packing and the first couple ring in multiple stages. The connecting pipe 40 attached to the lower end of the second pipe P2 is screwed to simplify the work process.

As described above, the deep well submersible motor pump protection pumping pipe 100 according to the present invention is guided so that the pumping pipe P can be smoothly inserted into the borehole H while being naturally sliding along the inner wall so as not to be damaged. Safely protect. The pumping pipe P is prevented from being damaged or broken by preventing the submersible motor pump and the pumping pipe from colliding with the inner wall of the borehole while the packing 10 and the first and second coupling rings 30 and 30a are firmly attached. As a result, the service life is greatly extended, and particularly the strong vibration and impact force of the submersible motor pump M are effectively absorbed and relaxed to ensure stable operation.

The present invention relates to an electric wire or cable connected to an underwater motor pump by safely protecting a pumping pipe and an underwater motor pump inserted into a borehole so as to be hit by a rock wall or prevented from being damaged. Stable operation is assured by guiding safely. This makes it possible to stably use a submersible motor pump installed deep in the ground without a long-term failure, as well as the fact that a borehole (deep well) is buried or closed and cannot be used ( This has the effect of preventing the situation) and facilitating maintenance.

In addition, the present invention has an effect that the packing is fixed to the step portion of the packing with a couple ring and firmly fixed with a guide, and the packing is easily fixed even in an external impact, and the durability is increased without being loosened.

Above all, the present invention enables mass production by couple rings cast into molds (molds) and castings, improving productivity, automating production processes and improving processes, processing costs and reducing production costs. It is accompanied by economic effects such as lowering prices.
