Description of the Related Art Conventionally, when a river, a lake, a road, or the like is temporarily flooded due to, for example, a typhoon or a torrential rain, there is a possibility that water may flow into a low ground or an underground. Stacking is used to prevent the inflow of water. However, this method is difficult and time-consuming, and in the worst case, it may not be possible to completely shut off the water. Therefore, there is known a water shutoff device in which the water shutoff wall rises in response to the rise of the water level (Japanese Patent Laid-Open No. 12-204527).

不十分であった。However, the conventional water shut-off device can shut off incoming water,
It was not possible to inform a person in advance that the blocking wall would start to rise. Furthermore, when the water overflows and the water blocking device is activated, it is unclear whether the ground or floor covered with the overflowing water is in a state where it can be safely walked, which is insufficient in terms of safety.

る。In order to solve the above-mentioned problems, the present invention comprises a recess into which water flows, and the recess includes:
A cover body is provided which is covered by the opening of the recess, the cover body is a projecting member projecting from an upper end of the recess in a state covered by the opening of the recess, and the cover body is covered by the opening of the recess. A member lighter than water is provided at a lower portion of the lid, and is formed so as to be rotatable around a pivot provided in the recess.

がる状態を視認することができる。[0006] With this configuration, the lid has a member lighter than water at the lower portion of the lid in a state where the lid is covered by the opening of the recess, so that when the recess is filled with water, buoyancy acts on the lid. Since the lid is formed so as to be rotatable around a pivot provided in the recess, the lid rises while rotating around the pivot. Furthermore, since the lid has a protruding member that protrudes from the upper end of the dent while being covered with the opening of the dent, it is possible to visually recognize the state in which the lid rotates and floats.

を阻止する壁となり水の流れが遮断される。Further, the water overflowing from the dent tends to flow to the lower side of the ground, and the pressure of this water causes the lid to rotate further about the pivot. If a means is provided for stopping the rotation when the lid rotates to the upright state, the lid becomes a wall for preventing the flow of water, and the flow of water is shut off.

なることを特徴とする。The present invention further comprises a first recess into which water flows, and a second recess into which water flows into the first recess when the water overflows, wherein the first recess has: A floating body having a bar-like portion that protrudes and retracts in the vertical direction according to the water level of the first dent is provided, and a lid that is covered by an opening of the second dent is provided in the second dent. The lid has a member lighter than water at a lower portion of the lid and is formed so as to be rotatable around a pivot provided on a side remote from the first recess.

満たされたことを視認することができる。By doing so, when the water flowing into the first dent overflows, the water flows into the second dent. When the first recess is filled with water, the floating body provided in the first recess floats. If the bar of the floating body is provided so as to protrude from the upper surface of the first dent, the bar of the floating body protrudes when the first dent is filled with water, and the first dent is filled with water. Can be visually recognized.

を阻止する壁となり水の流れが遮断される。Next, since a member lighter than water is provided on the concave side of the lid covered by the opening of the second concave, the lid is closed when the second concave is filled with water. Lifts up and rotates around a pivot. In addition, the overflowing water tends to flow to the lower side of the ground, which pressure causes the lid to rotate further about the pivot. If a means is provided for stopping the rotation when the lid rotates to the upright state, the lid becomes a wall for preventing the flow of water, and the flow of water is shut off.

し、逆回転阻止手段の作動を解除してから戻す。Further, it is preferable that the lid has reverse rotation preventing means for preventing reverse rotation when rotated about the pivot. Since the reverse rotation is prevented when the lid rotates around the pivot, even if the lid is put on the lid after it is rotated, it does not rotate backward and fall. When the water is pulled back to return the lid to its original position, the water accumulated in the dent or the second dent is discharged, and the operation of the reverse rotation preventing means is released before returning.

Water overflowing from the second recess 20 tends to flow to the lower side of the stairs 48, which pressure causes the lid 22 to rotate further about the pivot. The lid 22 serves as a wall for preventing the flow of water when the plate member 24 rotates to the upright state, so that even when the water level 34 is reached, the flow of water is shut off. Incidentally, the member 26 that is lighter than water is formed in a shape that is stepped when the lid 22 is in the upright state.

Even if a person is on top of 22, it does not fall. When returning the lid 22 to the position shown in FIG.
The accumulated water is discharged, and the locking of the reverse rotation prevention device 35 is released, and the lid 22 is rotated backward to return. In order to discharge the water accumulated in the second recess 20, a discharging means, for example, a pump or a separate discharge port is provided, and the water is discharged from this discharge port.

The lid 22 is gradually rotated by the hinge 32 until the plate member 24 stands. Therefore, it is possible to notify when the water shut-off device 1 operates. Further, even if the water level rises and rises as in the water level 55 beyond the upper end 50a of the embankment, the water of the river is prevented from flowing out of the embankment 50. When the water level 55 falls below the bottom of the second dent, the water in the second dent 20 flows out of the outflow / inflow hole 44b. The structure and operation of the other parts in FIG. 6 are the same as those of the water cutoff device of the first embodiment shown in FIGS.

きる。In this way, when the water level 54 rises, the water of the river is first stored in the space of the structure 58. When the water level further rises, the water flows into the second recess 20 from the inflow hole 44. When water flows in, the lid 22
Is rotated by the hinge 32 and stands upright. When the lid 22 rotates and stands up, the plate member 24 stands up. Therefore, even if the water level exceeds the upper end 50a of the embankment, the outflow of the river water is cut off and does not flow out of the embankment 50. In addition, plants, such as ivy 57, can be vegetated on the river side wall surface 58a of the structure to improve the aesthetic appearance.
