Description

Self-Rotating Tsunami and Blue Barrier {SELF ROTATING SURGE AND WAVE BARRIER}

The present invention relates to a self-rotating tsunami and wave protection wall, and more particularly, when a tsunami or wave occurs, it automatically rotates by buoyancy to easily prevent flooding, greatly reduce the amount of overshoot, and have a stable structure. It relates to a self-rotating tidal wave and wave barrier that is constructed.

In general, levees are used to block water from rivers, shores, lakes, or swamps to a certain height and width to prevent flooding due to flooding, and to protect against flooding caused by storm surges or waves. It refers to a civil structure built on top of concrete, etc.

Here, when designing the most representative concrete embankment, the water level at the point of flooding is identified, and an allowance of 0.5 to 2 m is added to determine the height of the embankment. Install while leaving

In other words, when the overflow height exceeds the maximum planned water level, when the surface of the embankment is deposited and the running water section is insufficient, when the ground subsides, when there is a wave, when the centrifugal force outside the curvature occurs, the water surface is This is to cope with various situations such as when ascending.

However, the concrete embankment not only impairs the aesthetics of the surrounding area, such as the coast, but also has a disadvantage that it feels uncomfortable because it is blocked so that the outside of the embankment cannot be seen from the inner side of the embankment.

For this purpose, a movable barrier device with a function to adjust the height according to the size of waves or tidal waves occurring at the shoreline is being developed, as in Korean Patent Publication No. 10-1828369 ('reservoir installation type movable barrier structure'). Existing movable barrier devices have a problem in that the structure for height adjustment or standing of the barrier consists of a hydraulic or mechanical actuator, wire, etc., and thus has a relatively weak bearing capacity.

And since the barrier structure installed in the vertical direction with respect to the ground has to be lowered in height than the barrier structure installed in an oblique direction in design for structural stability, the reliability of the overflow prevention function may be lowered. Because it is concentrated, there is also a problem in that it is difficult to disperse the impact caused by storm surges or waves.

Republic of Korea Patent Publication No. 10-1828369 (registered on February 6, 2018) Republic of Korea Patent Publication No. 10-1581193 (Registered on December 23, 2015)

Meanwhile, as shown in FIGS. 1 to 4 , the protection member 400 is accommodated in the second accommodating space 310 . One side of the protection member 400 is hinged to the upper edge of one side of the second receiving space 310 by a hinge pin (P), and the other side is accommodated in the second receiving space 310, and the second It forms a plane with the upper part of the protection body 300, and the other side stands around one side. That is, while being accommodated in the second accommodating space 310 and floating by the water accommodated in the second accommodating space 310 , it can stand up as the water level rises. That is, the protection member 400 can stand up by buoyancy without a separate driving unit.

In this embodiment, the other side of the protective member 400 is manufactured in an arc shape around one side. That is, the protective member 400 is formed such that the thickness from the upper end to the lower end gradually increases as it goes from one side to the other side, and its cross section forms a sectoral shape. This is because it is possible to minimize the contact area with water and at the same time to attenuate the impact, so that the over-wave can be more effectively reduced.

And when the upper end of the protective member 400 is level with the upper portion of the second protective body 300 , the lower end is in surface contact with the support member 320 . In this way, when the protective member 400 is used as a hydrophilic deck, it can be stably and firmly supported even if it receives a force from a load such as a person or a vehicle passing the upper part of the protective member 400. .

At this time, water is introduced into the first accommodating space 210 of the first protective body 200 through the first inlet 220 .

In this state, as shown in FIG. 6 , when the water level gradually reaches a dangerous water level that is likely to overflow inland, a larger amount of water is introduced into the first accommodation space 210 to raise the water level. while the water is introduced into the second accommodating space 310 through the first flow pipe 240 .

Here, since the second accommodating space 310 has only a space sufficient to accommodate the protection member 400, the water level flowing into the second accommodating space 310 is higher than the time when the water level rises. can rise quickly. At the same time, since water flows in through the through hole communicating with the second accommodating space, the protection member 400 may float more quickly.

Meanwhile, as shown in FIG. 7 , when a tsunami or wave occurs, water may overflow to the upper side of the first protection body 200 . At this time, as water is introduced through the second inlet 230 , water is introduced into the second accommodating space 310 .

Therefore, even when a tsunami or wave occurs as well as a rise in water level, water can be introduced into the second accommodating space 310 through the second inlet 230, so that the protection member 400 is automatically activated by buoyancy. can be rotated. Therefore, even in various environments, the protection member 400 is accurately operated without a separate driving unit, thereby easily preventing the over-wave.

In addition, at the same time as circulating the wave incident by the protection member 400 and the half-hole member 420, it is possible to attenuate the contact impact with water through the arc-shaped protection member 400, so that the can be effectively reduced.

At the same time, as shown in FIG. 7 , the stopper 430 is hung on the hanging member 340 to restrict the rotation of the protection member 400 , so the protection member 400 is arbitrarily used for the second protection. Deviation from the body 300 is prevented.

A support plate is provided inside the protective member in a vertical direction from the inside of the upper end to the lower end of the protective member,
A support member selectively in contact with the lower end of the protective member is provided on the bottom surface of the second accommodating space,
The protection member is
Self-rotating tsunami and wave protection wall, characterized in that when the upper end is level with the upper portion of the second protective body, the lower end is in surface contact with the support member.
The method of claim 1,
Self-rotating tsunami and wave protection wall, characterized in that it comprises a half-hole member extending in the horizontal direction from the upper end of the other side of the protection member to reduce the overpass.
3. The method of claim 2,
A hanging member is formed on the upper inner edge of the second protective body facing the other upper end of the protective member to protrude in the horizontal direction,
Self-rotating tsunami and wave protection wall, characterized in that when the upper end of the protection member is level with the upper portion of the second protection body on the upper portion of the hanging member, the anti-breaking member is in surface contact
4. The method of claim 3,
