TECHNICAL FIELD The present invention relates to the field of pipe descalers, and more particularly, to a flexible wire that is inserted into a pipe and rotates at high speed during operation of the device to remove the scale generated in the pipe by hitting.

In general, the pipe serves as a passage for guiding and moving water or other fluid to a predetermined place, and is mainly installed and used in the form of being buried in the floor or wall of a building.

In addition, the pipe as described above is oxidized and corroded to the inner wall surface for a long time, as well as various foreign substances cling to the inner wall to create a scale, these scales are solidified over a long time causes a narrowing of the flow path of the pipe.

If the flow path cross-sectional area of the pipe is narrowed by the scale as described above, the fluid will not move smoothly, and the pipe function will not function as designed. In severe cases, the pipe may be damaged by the moving pressure of the fluid. If so, it should be removed immediately to allow it to perform its normal role as a pipe.

Therefore, a method of allowing the scale to melt while passing chemically added water into the pipe to remove the scale in the pipe causes a chemical reaction as the chemical contained in the water comes into contact with the scale. have.

However, the method of removing the scale of the pipe by the chemical requires an additional device such as an air sprayer, and due to the use of the chemical, great care must be taken in the construction process, and damage to the pipe caused by the chemical in the process of removing the scale is caused. And, because the chemical is expensive, there are a number of problems, such as a lot of construction costs.

In addition, no matter how harmless the chemicals used to remove the pipe scale, the consumer who uses water is insecure. Especially, in general households, it is extremely negative to remove the scale. Is not easily solved.
Pipe descalers developed to solve the above problems are known.
As shown in FIGS. 1 and 2, a typical pipe descaler inserts a flexible wire into a pipe and then rotates the flexible wire at high speed to repeatedly rotate the flexible wire in which the scale generated inside the pipe is rotated. Follow the way to crash and fall.
That is, when the operator inserts the flexible wire 1 into the pipe and drives the motor 2 at high speed, the driving force of the motor 2 is transmitted to the flexible wire 1 and the flexible wire 2 is It rotates at high speed in the guide pipe (3). This rotational force causes the flexible wire 1 outside the guide tube 3 to swing largely, causing the flexible wire 1 to strike the pipe inner diameter surface. The scale generated inside the pipe is removed away from the pipe inner diameter surface by the strike of the flexible wire 1.
Since the pipe descaling machine does not use any chemicals, it is particularly popular among the residents of apartments and multi-family houses that are supplied with drinking water.
However, the conventional flexible wire 1 applied to the pipe descaler for removing the scale inside the pipe by hitting as described above is twisted in a spiral in a state where several strands are joined together as shown in FIG. 3. As an integrated structure, it has a structure consisting of a single straight main wire as a whole.
Therefore, the conventional flexible wire has a problem that it is difficult to remove the scale for large diameter pipes because the blow diameter due to the centrifugal force can not be limited when the high speed rotation in the state inserted into the pipe in the use process.

In order to solve the above problems, if the diameter of the main wire of the flexible wire is increased to increase the centrifugal force, the flexibility of the flexible wire decreases in proportion to the diameter of the flexible wire. Thus, as a conventional flexible wire, the scale of a pipe having a large diameter is removed. There is no limit to this.

The present invention has been made in order to solve the above-mentioned conventional problems, and the object of the present invention is to make it possible to smoothly remove scales generated in large diameter pipes by increasing the diameter of rotation due to centrifugal force during high speed rotation.

The object of the present invention is the main wire is twisted in a spiral in a state in which several strands are joined to each other and are integrated to form a single straight shape as a whole; Auxiliary wires which are twisted in a spiral shape and integrated in a state in which several strands are joined to each other so as to form a smaller diameter than the main wire, and fixed in the main wire while being continuous in an S-shape as a whole; And a binding member for enclosing and enclosing the main wire and the auxiliary wire at a point where the main wire and the auxiliary wire cross each other.

On the other hand, the binding member is preferably a wire wound on the outside of the main wire and the auxiliary wire.

Alternatively, the binding member may include a U-bolt installed at a point where the main wire and the auxiliary wire intersect to surround the main wire and the auxiliary wire at the same time, and a pair of through holes formed at both ends of the U bolt. It may have a support plate which is fitted to both ends of the u-bolt through the through hole and coupled to both ends of the u-bolt penetrating the support plate, respectively, and a tightening nut for close contact with the main plate and the auxiliary wire side.

In the above cases, it is preferable that at least one side of the main wire and the auxiliary wire is further provided with a groove portion engaged with each other at each intersection so that the main wire and the auxiliary wire intersect with each other.

Prior to the detailed description of the present invention, since the pipe scale remover to which the present invention is applied has the same structure and operation as the conventional pipe scale remover, a detailed description thereof will be omitted.

As shown in Figures 4 to 6, the present invention is the main wire 110 and the main wire 110 that is integrally twisted in a spiral in the state in which several strands are combined with each other to form a single straight shape as a whole, the main wire 110 In the state where several strands are joined together to form a smaller diameter, they are integrally twisted in a spiral shape and are fixed to the main wire 110 in a state of being continuously crossed in an S-shape as a whole, and thus, when the main wire 110 is rotated. The auxiliary wire 120 rotates together, and the binding member 130 for enclosing and enclosing the main wire 110 and the auxiliary wire 120 at a point where the main wire 110 and the auxiliary wire 100 cross each other. It is composed.

When the flexible wire 100 is composed of the main wire 110 and the auxiliary wire 120, when the auxiliary wire 120 is rotated together in accordance with the rotation of the main wire 110, the overall rotation diameter by the centrifugal force is the auxiliary It is much larger than without the wire 120, which is more advantageous for removing relatively large diameter pipe scales.
In addition, the diameter of the auxiliary wire 120 should be made smaller than the diameter of the main wire (110). This is because the diameter of the main wire 110 holding the centrifugal force at the time of high speed rotation must be larger than the diameter of the auxiliary wire 120 so that the flexible wire 100 can be rotated at a high speed by the centrifugal force. .

On the other hand, the binding member 130 for enclosing the main wire 110 and the auxiliary wire 120 to bind together may be composed of a wire wound on the outer side of the main wire 110 and the auxiliary wire (120). In this case, the binding member 130 should be made of a material having sufficient strength to firmly bind the main wire 110 and the auxiliary wire 120 even in a state of rotating at high speed, and should not have elasticity. The binding member 130 is not limited to the number of times surrounding the main wire 110 and the auxiliary wire 120.

In addition, both ends of the binding member 130 are bound to prevent loosening in a state in which the main wire 110 and the auxiliary wire 120 are wrapped. The manner of binding both ends of the binding member 130 need not be limited, and for example, various methods such as tying both ends of the binding member 130 or using a separate pressing member or bonding through bonding may be possible.

If the binding member 130 is an iron wire, as shown in the figure, the both ends of the iron wire may be twisted a plurality of times.

On the other hand, as shown in Figure 7 and 8, the binding member 140, the point where the main wire 110 and the auxiliary wire 120 intersects so as to surround the main wire 110 and the auxiliary wire 120 at the same time. A support plate 142 having a u-bolt 141 installed on the u-bolt 141 and a pair of through-holes formed at both ends of the u-bolt 141 to be inserted into and coupled to both ends of the u-bolt 141 through the through-holes; The fastening nuts 143 may be fastened to both ends of the u-bolt 141 penetrating the support plate 142 to closely contact the support plate 142 toward the main wire 110 and the auxiliary wire 120.

Therefore, the u-bolt 141 is positioned at the intersection of the main wire 110 and the auxiliary wire 120, the support plate 142 is inserted at both ends of the u-bolt 141, and the fastening nuts (at both ends of the u-bolt 141). When the fastener 143 is fastened, the support plate 142 is brought into close contact with the main wire 110 and the auxiliary wire 120 by the tightening operation of the fastening nut 143, and thus the support plate 142 is assisted with the main wire 110 by the tightening operation of the fastening nut 143. Bonding of the wire 120 is made firm.

Meanwhile, as shown in FIGS. 9 and 10, at least one side of the main wire 110 and the auxiliary wire 120 is provided with groove portions 150 corresponding to each other so as to cross each other in an engaged state at each intersection point. It is preferable.

In this case, since the main wire 110 and the auxiliary wire 120 are engaged with each other by the groove 150, the binding force is greatly improved. In addition, since the auxiliary wire 120 may be cross-installed at uniform intervals along the groove 150 formed in the main wire 110, the installation of the auxiliary wire 120 may be very simple and accurate.

In addition, depending on the diameter of the pipe, the crossing distance between the main wire 110 and the auxiliary wire 120 should also vary. Therefore, the grooves 150 do not necessarily need to be formed at a predetermined interval, and the intervals of the grooves 150 may be formed at different intervals so that the intervals can be easily set by appropriately selecting the grooves 150. Do.
The flexible wire according to the present invention can be used limited to the portion drawn out from the guide tube of the pipe scale remover.
In addition, if necessary, the pipe scale remover may be a part of the design change appropriately to apply the flexible wire according to the present invention.

According to the flexible wire for pipe descaling device of this invention comprised as mentioned above, it has the following effects.

First, since the auxiliary wires in a S-shape are fixed to the straight main wire, the rotation diameter is wide due to the centrifugal force during high-speed rotation, which makes it possible to smoothly remove scales generated in large diameter pipes, and also removes scales. There is an effect that can be greatly improved.

Second, since the main wire and the auxiliary wire are firmly bound by the binding member provided at the point where the main wire and the auxiliary wire cross, the main wire and the auxiliary wire are not separated or damaged when the pipe scale is removed.

Third, in the case where the groove portion which is engaged with each other in the main wire and the auxiliary wire is further formed, not only the binding force of the main wire and the auxiliary wire is greatly improved, but also the cross spacing of the auxiliary wire can be easily and uniformly adjusted and the cross spacing can be easily adjusted. It has an effect.

While the invention has been shown and described with respect to specific embodiments thereof, it will be understood that the invention can be variously modified and varied without departing from the spirit or scope of the invention as set forth in the claims below. It should be included in the scope of the invention.
