Description

Ordering Device {APPARATUS FOR CLOSING WATER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water order device, and more particularly, to a water order device that blocks a flow of water flowing into a residential area during a tsunami or flood.

In order to prevent flooding of residential areas due to tsunamis and floods, it is effective to construct a levee on the coast or a river bank.However, if a levee is constructed, traffic from the levee will be cut off, causing the normal living environment to deteriorate. There is.

Therefore, conventionally, a part of the levee was removed to install a passage and at the same time, a sliding door for sliding doors was used in the passage.

In general, watertight doors were opened to pass cars and people, and when there was a risk of tsunamis or floods, the watertight doors were closed to prevent water from entering the residential area.

However, when the waterproof door is moved by human hands, it is difficult to open and close the waterproof door quickly. In addition, when the waterproof door is moved by electric power (motor, etc.), there is a fear that the door may become inoperable during a power failure.

It becomes a part of a linear or rod shape compressed in between. In this embodiment, the horizontal part 84b is arrange | positioned in the position corresponding to the connection part 80 on the 1st surface 71a.

As shown in FIG. 7, when the protrusion 82 contacts the first portion 87a of the contact surface 87 in the rail portion 68, the first surface 71a and the inner frame 62 of the order wall 70. The first gap K1 is secured between the first inner surfaces 63a of the surface.

On the other hand, as shown in FIG. 10, when the protrusion 82 is inserted into the depression 85, between the first surface 71a of the order wall 70 and the first inner surface 63a of the inner frame 62 and the order wall ( A second gap K2 is formed between the first surface 71a of 70 and the third inner surface 27 of the opening 26.

The width of the second gap K2 is formed to be narrower than the width of the first gap K1 by the depth of the recess 85, and the thickness of the packing 84 is substantially the same as or the width of the first gap K1. Slightly larger than The packing 84 is also provided sufficiently larger than the width of the second gap K2.

In other words, when the order wall 70 rises due to the buoyancy of water flowing into the reservoir 20, the protrusion 80 contacts the contact surface 87 of the rail portion 68, and the first surface 71a of the order wall 70 is formed. ) And a first gap K1 is secured between the first inner surface 63 of the inner frame 62. On the other hand, when the order wall 70 rises to the uppermost level and the protrusion 82 is inserted into the recess 85, the first surface 71 a of the order wall 70 and the first inner surface 63 of the inner frame 62 are formed. A second gap K2 narrower than the width of the first gap K1 is formed therebetween.

Accordingly, the compression rate of the packing 84 compressed in the first gap K1 is less than that of the packing 84 compressed in the second gap K2, so that the packing 84 compressed in the first gap K1 is compressed. And the first frictional force generated between the first inner surface 63 or the first surface 71a is between the packing 84 compressed in the second gap K2 and the first inner surface 63 or the first surface 71a. It becomes smaller than the created 2nd frictional force.

As a result, it is possible to prevent the fast and reliable operation of the order device due to the first frictional force from being disturbed.

Hereinafter, the operation of the order device according to the present invention will be described in detail.

As shown in FIG. 2, when a water level such as a sea or a river rises to a predetermined height (H) during a tsunami or flood, water (W) flows into the reservoir 20 through the intake pipe 24a and flows into the reservoir 20. The order wall 70 rises by the buoyancy of the water W which entered.

As shown in FIG. 7, the water pressure of the water W acts on the second surface 71b of the order wall 70, but the first surface 71a of the order wall 70 and the first inner surface of the inner frame 62. Since the 1st clearance K1 is ensured by the protrusion part 82 between 63a, it is possible to prevent the packing 84 from being overcompressed.

Therefore, the frictional resistance between the packing 84 and the first inner surface 63a is reduced to prevent the raising operation of the order wall 70 from being disturbed.

Thereafter, when the water level rises further and the water W flows to the ground G, the water W flows into the water reservoir 20 through the intake port 44. 10 and 11, when the reservoir 20 is full due to the inflow of water (W), the order wall 70 is raised to the highest value to form the order state.

In this order, the projection 82 is fitted into the recess 85, so that between the first surface 71a of the order wall 70 and the first inner surface 63a of the inner frame 62 and of the order wall 70. A second gap K2 is secured between the first surface 71a and the third inner surface 27 of the opening 26.

Since the thickness of the packing 84 is designed to be sufficiently larger than the width of the second gap K2, the packing 84 is compressed at a high compression ratio in the second gap K2. Accordingly, the gap between the order wall 70 and the inner frame 62 and the gap between the order wall 70 and the inner circumference 26a of the opening 26 are secured to prevent leakage of water.

When the water (W) overflowed to the ground (G) is released, the valve 40 is opened to drain the water (W) stored in the reservoir 20 through the first drain pipe (38). When the drainage of the water W is completed and returned to the normal state, the valve 40 is closed to prevent the water W from flowing back through the first drain pipe 38.
