However, in transporting seawater and fresh water such as deep sea water, there is a concern of lack of cleanliness due to corrosion, and low temperature energy loss due to heat exchange with the outside environment, so that the appropriateness of polyethylene material is emphasized rather than steel pipe.

In order to preserve deep water, PE (high density polyethylene) pipe is generally used to collect deep sea water. It must be reinforced. In particular, in order to preserve the characteristics of clean deep sea water, not only pipes but also reinforcements must be safe from corrosion by sea water.

Polyethylene (PE) tubes are mainly used which have the advantage of maintaining the cleanliness and low temperature of the transport fluid. The polyethylene pipe (hereinafter referred to as flexible pipe) is extruded and cut to a certain length, and the flexible pipe having a certain length has a long length, so that the sides of both ends are melted and joined because the connection is not easy. At this time, the bead 200 is formed inside the connection portion of the flexible pipe 100 as shown in FIG.

Such the present invention has the effect of preventing the clogging of the pipe by removing the beads generated in the connecting portion to prevent the interference of fluid transfer to increase the efficiency and to prevent foreign matter deposition.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2A is an exploded perspective view showing the structure of the bead removing device of the flexible tube to which the technique of the present invention is applied, and FIG. 2B is a combined perspective view showing the structure of the bead removing device of the flexible tube to which the technique of the present invention is applied, and FIG. As a side view showing the installation state of the bead removal device of the flexible pipe to which the technique of the present invention is applied, the bead removal method of the flexible pipe according to the present invention is one-way after inserting the bead removal blade means to the bonded portion inside the flexible pipe When rotated 180 degrees, the folded blade member is developed, and when the blade member is deployed, the entire bead removal blade means is rotated so that the bead is cut by the blade member.

The bead removal method of the flexible pipe of the present invention as described above is implemented by the bead removal device of the flexible pipe shown in the accompanying drawings. The bead removal device of the flexible pipe is a rotating rod connecting portion 20 having a support roller 11 rotatably arranged in the bracket 10 and the bracket 10 welded to the bracket 10 and having a coupling hole 21. It consists of a bead removal blade means 30 is rotatably installed on the bracket (10).

The bracket 10 has a structure in which a support roller 11 is rotatably arranged and a first plate 10a and a long hole 16 provided with a flow preventing pin 13 around the through hole 12 in the center thereof. And both sides are provided with a plurality of position adjusting holes 14 at regular intervals, and through the second plate (10b) and the through-hole 12 formed with a stopper bar 15 on one side of the rotary rod connecting portion 20 ) Is a structure consisting of a coupling rod (10c) has a spiral formed on the outer circumferential surface to be coupled to the fixing nut.

The bead removing blade means 30 is a gap retaining rod 31 and a fixed plate member 32 fixed to the gap retaining rod 31 and the fixed plate member 32 and the bracket 10 installed to maintain a constant interval The rotatable installation between the body is provided with a fixing hole and one side detachably installed on the blade fixing frame 33 and the blade fixing frame 33 formed by including an angle holding bar (33a) formed integrally with the body. The blade member 34 is made of a structure.

Meanwhile, as shown in FIG. 6, the end of the coupling rod 10c may further include a drawing means 50 having an elastic force to draw the cut bead 200 out of the flexible pipe.

The operating state of the present invention having the structure as described above is connected to the rotary rod to the rotary rod connecting portion 20, as shown in Figure 3 attached to the bead removal device (1) of the flexible pipe installed inside the flexible pipe After pushing, the support roller 11 is caught in the bead 200 formed inside the flexible pipe, thereby restricting entry.

At this time, the withdrawal means 50 installed at the end of the coupling rod 10c is slightly compressed by the beads because of the elastic force, and then, after passing through the beads 200, is restored to its original position and introduced into the flexible pipe.

When the entry of the bead removal device 1 is restricted by the bead 200, the worker can naturally grasp the position of the bead 200. In this case, the bead removal device 1 is shown in FIG. 4A. The bead removal blade means 30 is provided in a folded state.

Meanwhile, when the support roller 11 is caught by the bead 200 and the entry is restricted, the worker rotates the rotary push rod connected to the rotary rod connecting part 20 as shown in FIG. Position movement occurs in the downward direction (30).

When the operator rotates the entire bead removal device 1, the support roller 11 is rotated along the inner surface of the flexible pipe. In addition, the bead removal blade means 30 is rotated and unfolded by its own weight.

The blade member 34 of the bead removal blade means 30 extended by the self-weight is lodged in the bead 200, and as the bead is continuously rotated as shown in FIG. And removed.

Meanwhile, the operation of the rotating bead removing blade means 30 will be described in more detail. As shown in FIG. 4B, only a predetermined angle is rotated when the blade member 34 fixed to the blade fixing frame 33 is rotated. The reason is that the angle retaining bar (33a) integrally formed in the body of the blade fixing frame (33) is caught by the gap retaining rod 31, the rotation is limited to a certain angle.

As shown in FIG. 6, after removing the bead 200 from the flexible pipe and removing it, the bead removal device 1 is rotated to move the bead removing blade means 30 to the upper side as shown in FIG. 4A. The blade means 30 is folded to an initial state.

The reason why the rotation is possible to maintain the initial position when folding is because the body of the blade fixing frame 33 is caught by the stopper bar 15 provided in the second plate (10b) is limited rotation.

On the other hand, when the bead removal blade means 30 is folded in the initial state as described above, when the operator pulls the rotary push rod to the rotary rod connecting portion 20, the bead cut out to the withdrawal means 50 installed at the end of the coupling rod (10c) 200 is caught and drawn out of the flexible tube.

On the other hand, since the size of the flexible pipe is not the same, the height of the bracket 10 is adjusted so that the flexible pipe can be used universally for different diameters. Adjusting the height of the bracket 10 is inserted into the position adjusting hole 14 of the second plate 10b to the flow preventing pin 13 of the first plate 10a as shown in FIG. The minimum diameter D1 of the tube is when the flow prevention pin 13 is inserted into the positioning hole 14 of the upper end, and the maximum diameter D2 of the flexible pipe is fitted with the flow prevention pin 13 into the positioning hole 14 of the lower end. When it is On the other hand, the nut 16 is screwed through the coupling rod 10c through the long hole 16 of the second plate 10b to prevent complete separation of the first plate 10a and the second plate 10b.

The present invention has the effect of preventing the clogging of the pipe by removing the beads (200) generated in the connecting portion to prevent the interference of fluid transfer to increase the transport efficiency of deep sea water and to prevent foreign matter deposition.
