The defense tower system according to an embodiment of the present invention is shown in a reduced state when gas discharge is not required, and thus may be covered in a basic structure on the ground when gas discharge is not required.

In addition, since pneumatic pressure is used, noise is not generated, the expansion and construction speed is fast, and the risk of blasting is lowered, unlike the existing defense tower system.

Conventionally, a defense tower system using pneumatic did not exist, because it was technically impossible to expand and construct a defense tower system without noise using only pneumatic pressure. The structure of the defense tower system has made it possible to expand and contract a plurality of pipe parts 200 without noise by using pneumatic pressure.

2 is a view showing a state in which all the defense towers of the defense tower system according to an embodiment of the present invention are extended, and FIG. 5 is a pneumatic pressure in the process of extending the defense tower of the defense tower system according to an embodiment of the present invention. It shows the flow of.

2 and 5, the pipe part 200 may be broadly divided into two parts and extended.

More specifically, the pipe portion 200 includes an inner pipe portion 230, I providing a path through which gas moves, and an outer pipe portion 210, O that pulls and extends the inner pipe portion 230, I. It may be provided to include.

When all the defense towers of the defense tower system according to an embodiment of the present invention are elongated, the uppermost pipe structure 231 provided at the uppermost end of the inner pipe parts 230 and I is of the outer pipe part 210 and O. It is provided in the same manner as the uppermost pipe structure 231 provided at the uppermost end.

That is, when the pneumatic pressure starts to be supplied to the lower chamber of the defense tower, the outer pipe portions 210 and O first start elongation as shown in FIG. 5 (a).

In this case, when the outer unit pipe portions 213, 215, 217, 219 constituting the outer pipe portions 210, O rise to a predetermined height, the inner pipe 210 is The pneumatic pressure becomes available, and the inner unit pipe portions 233, 235, 237, 239 constituting the inner pipe 210 rise sequentially, and the inner unit pipe portions 233, 235, 237, 239 located inside the inner pipe portion 233, 235, 237, 239 ) Will rise together.

Therefore, if the conventional defense tower system takes a structure in which each unit pipe rises sequentially, the defense tower system according to the embodiment of the present invention has a slight time difference, but the inner pipe and the outer pipe rise substantially at the same time. Therefore, there is an advantage that the time required for the defense tower to be elongated is saved considerably.

3 is an enlarged view of the outer pipe portion of the defense tower system according to an exemplary embodiment of the present invention in which part A of FIG. 2 is expanded.

For convenience of explanation, only two pipes are shown from the bottom to be described.

Referring to FIG. 3, of the multi-stage unit pipes forming the outer pipe part 210, other unit pipes other than the unit pipe (not shown) located at the top and the unit pipe 211 located at the bottom are on the outer circumferential surface. It may be provided to include the lower stopper (2133, 2153) and sealing members (2135, 2155).

In addition, other unit pipes other than the unit pipe positioned at the top of the multi-stage unit pipes constituting the outer pipe part may be provided to include upper stoppers 2111 and 2131 provided on the inner circumferential surface.

When pneumatic pressure is supplied to the interior of the defense tower according to an embodiment of the present invention, other unit pipes other than the unit pipe 211 located at the lowest end move toward the top and the defense tower expands as a whole. As the unit pipes rise, the lower stoppers 2133 and 2153 also rise to the point where they meet the upper stoppers 2111 and 2131.

At this time, the upper stopper (2111, 2131) prevents the rise of the lower stopper (2133, 2153), each of the unit pipes forming the additional outer pipe portion 210 is raised to a predetermined height or more from the outer pipe portion (210). It plays a role in preventing churn.

Meanwhile, the sealing members 2135 and 2155 may be provided to be spaced apart from the lower stoppers 2133 and 2153 at a predetermined interval.

More specifically, the sealing members 2135 and 2155 may be provided to be spaced apart from the lower stoppers 2133 and 2153 by a length of 15% to 30% of the total length of each unit pipe.

As described above, since the sealing members 2135 and 2155 are provided to be spaced apart from the lower stoppers 2133 and 2153 by a predetermined distance, the unit pipes are more stably extended when the unit pipes are raised by pneumatic pressure. Since it can be fixed, there is an effect that can increase structural stability.

Meanwhile, the lower stoppers 2133 and 2153 and the sealing members 2135 and 2155 may include a body and a Teflon ring-shaped sealing member provided on an outer circumferential surface of the body.

The sealing members 2135 and 2155 may also be provided with a Teflon member cut in half. Unlike the lower stoppers 2133 and 2253, the Teflon sealing member is stacked in duplicate so that the cut part is offset, so the flow of air Can be prevented.

The reason why the ring-shaped Teflon member is cut in half and used as described above is that the Teflon member is not highly ductile, and there is a side that is difficult to extend and attach like a rubber band.

Accordingly, the present invention has the effect of solving the above-described problem and realizing the sealing function by providing the Teflon sealing member so as to be double-stacked so that the cut portion is shifted.

Since the lower stopper (2133, 2153) and the sealing member (2135, 2155) is expected to move up and down according to the supply amount of pneumatic pressure, the lower stopper (2133, 2153) and the sealing member (2135, 2155) A ring-shaped sealing member made of a Teflon material with strong abrasion resistance on the outer circumferential surface of the body has the effect of protecting the body from abrasion.

This means that the unit pipe 231 positioned at the top of the multistage unit pipes constituting the inner pipe part 230 and the unit pipe positioned at the top of the multistage unit pipes constituting the outer pipe unit 210 are provided identically. .

The unit pipe 231 located at the top end is provided on the outer circumferential surface of the unit pipe located at the top end, and the unit pipe located at the top end when the unit pipe 231 located at the top end is elongated to a maximum height by pneumatic pressure. A lower stopper 2311 in surface contact with the upper stopper 2191 provided in the unit pipe 219 provided outside of the 231, is provided on the outer circumferential surface of the unit pipe 231 located at the uppermost end, A unit pipe provided at a predetermined distance from the lower stopper 2311 and provided on the inner circumferential surface of the first sealing portion 2313 blocking the flow of air and the unit pipe 231 positioned at the uppermost end, and positioned at the uppermost end. It may be provided to include a second sealing portion 2315 provided to pull the unit pipe 233 provided in the inside of 231.

The first sealing part 2313 and the second sealing part 2315 are provided so that the Teflon sealing member cut in half so as to seal the pneumatic pressure supplied to the interior of the defense tower is double-stacked so that the cut part is shifted. I can.

On the other hand, in the case of the lower stopper 2311, there is no need for sealing, but since there is a need to prevent abrasion of the body due to continuous up-and-down action, a single Teflon sealing member cut in half is provided for cost reduction. Can be.

In addition, the unit pipe 233 provided inside the unit pipe 231 positioned at the uppermost end is provided on the outer circumferential surface of the unit pipe 233 provided inside the unit pipe 231 positioned at the uppermost end, and the An inner support portion 2331 in surface contact with the inner circumferential surface of the unit pipe 231 positioned at the uppermost end, a towed portion 2333 provided to be spaced apart from the inner support portion 2311 by a predetermined distance, and a unit pipe 231 positioned at the uppermost end. ) Is provided on the inner circumferential surface of the unit pipe 233 provided inside of the unit pipe 231 located at the top of the unit pipe 231 provided inside the unit pipe 233 ( 2335) may be included.

The to-be-drawn part 2333 does not require sealing, but since there is a need to prevent abrasion of the body due to continuous up-and-down action, a single Teflon sealing member cut in half may be provided to reduce cost.

On the other hand, since the traction part 2335 needs to be sealed, the Teflon sealing member cut in half to seal the pneumatic pressure supplied to the interior of the defense tower may be provided to be double stacked so that the cut portion is shifted. .

Therefore, due to this structural feature, the diameter of the multi-stage unit pipes forming the inner pipe part 230 may be provided so as to become narrower toward the bottom.

Among the multi-stage unit pipes constituting the inner pipe part 230, other unit pipes other than the unit pipe 231 located at the top end have a towed part 2333 on the outer circumferential surface, and a traction part 2335 is installed on the inner circumferential surface. I can.

That is, the to-be-drawn part 2333 is provided at an upper end than the traction part 2335, so that when the external unit pipe rises among the multi-stage unit pipes forming the inner pipe part 230, the internal unit pipe is It can provide an ascending traction.

High heat resistance is required because high-temperature gas flows inside the inner pipe part 230, and high wear resistance is required because the inner pipe part and the outer pipe part are provided to be periodically expanded and contracted so that the unit pipes perform relative motion.

Therefore, when a Teflon material having high heat resistance and abrasion resistance is used, there is an effect of reducing unnecessary maintenance despite repeated expansion and contraction of the inner pipe portion and the outer pipe portion.

On the other hand, the present invention is not limited to the described embodiments, and it is apparent to those of ordinary skill in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention.
