Description

  The present invention relates to an overflow prevention device that automatically protects against the occurrence of overflow of a house or the like due to a tsunami, bank break, heavy rain, or the like.

Conventionally, when there is a risk of flooding a house or the like due to a tsunami, a bank break, heavy rain, etc., it is generally taken to prevent flooding by stacking “sandbags” (see, for example, Patent Document 1). ).
Furthermore, as a means for preventing flooding quickly, there is also an assembly-type “water-impervious wall” that is used (see, for example, Patent Document 2).

JP 2009-293260 A JP 2004-68271 A

  When the above-mentioned “sandbag” is used, time is taken for the work, and if it is not piled up in advance, it will not be in time for the occurrence of overflow. Furthermore, since the accumulation involves remarkable workability, it is limited to installation in extremely narrow areas such as entrances and stores in ordinary households, and installation in large areas is impossible without the assistance of specialized labor. It was done.

  In addition, in the case of the above-mentioned “water-impervious wall”, a certain degree of speed can be obtained, but it is still necessary to prepare by hand before the occurrence of overflow, and if the installation is delayed, it is said that “it was not in time” It will lead to such a situation. And since the installation is a small number of people, manpower is required, so there is a problem of securing workers.

  The present invention is preliminarily installed in the ground of a required location, and when a flood or the like rushes, the water shielding panel automatically protrudes and measures against overflow are achieved by the force of the rushed water. It is intended to provide new technology.

The present invention provides a plate-like float between a flat plate portion having a size covering the upper surface opening of the substrate block and leg-shaped frame rods suspended from both sides in the substrate block having a groove shape of the upper surface opening. Is a flood prevention device in which a water shielding panel is mounted so that it can be raised and lowered, and receives flowing water from a gap formed at the upper edge of one side of the base block, and the gap on the other side is It is closed so that water does not leak from the gap by elastically closing it without hindering the raising and lowering of the water shielding panel, and the base block is directed to the overflow side and the other side is prevented from overflowing. The water- impervious panel rises based on the buoyancy of the base block and the water- blocking panel rises based on the buoyancy of the base block. Flood protection designed to work Device in accordance with the.

The present invention provides a plate-like float between a flat plate portion having a size covering the upper surface opening of the substrate block and leg-shaped frame rods suspended from both sides in the substrate block having a groove shape of the upper surface opening. Is a flood prevention device in which a water shielding panel is mounted so that it can be raised and lowered, and receives flowing water from a gap formed at the upper edge of one side of the base block, and the gap on the other side is It is closed so that water does not leak from the gap by elastically closing it without hindering the raising and lowering of the water shielding panel, and the base block is directed to the overflow side and the other side is prevented from overflowing. The water- impervious panel rises based on the buoyancy of the base block and the water- blocking panel rises based on the buoyancy of the base block. Because it was configured to work, By installing the flood prevention points in advance, when heavy rain, flooding, tsunami, etc. occurs and water is pushed in, the water shielding panel A is automatically raised, and overflow occurs on the protected objects. Will be prevented in advance. And the water stored in the base | substrate block does not flow into the overflow prevention side.

  Therefore, as in the past, it occurred when depending on emergency construction of "sandbag" stacking or assembly type "water-impervious wall" that was built in the event of heavy rain, flooding, tsunami, etc. The problems such as the necessity of great labor and the necessity of the installation work immediately before are completely solved.

It is a vertical front view of the present invention. It is the XX sectional view taken on the line in FIG. It is a top view of the present invention. It is sectional drawing for description showing the installation state of this invention, and cut | disconnected by the YY line | wire in FIG. It is sectional drawing for description showing the state which act | operated from the state of FIG. 1 is a schematic diagram showing one basic use example of the present invention.

  In the figure, reference numeral 1 denotes a base block having a groove shape with an upper surface opening, which comprises a front plate portion 1a, a back plate portion 1b, and a bottom plate portion 1c. The base block 1 is constructed so as to be buried in a place for preventing overflow with its upper edge aligned with the ground surface (see FIGS. 4 and 5).

  A is a water shielding panel, and includes a lifting frame 2 and a plate-like float 3 described below, and is housed in the base block 1 so as to be lifted and lowered.

Reference numeral 2 denotes the lifting frame, which comprises a flat plate portion 2a having a size enough to cover the opening on the upper surface of the base block 1 and leg frame rods 2b and 2b suspended from both sides thereof. It is.
When the lower end of the elevating frame 2 is in contact with the bottom plate portion 1c when the base block 1 is housed in the base block 1, the upper end of the base frame 1 exceeds the upper edge of the base block 1. A water inflow gap M is formed between the flat plate portions 2a.

  Reference numeral 2c denotes a linear slider which is attached to the front and rear surfaces of the leg-shaped frame rods 2b and 2b in a protruding state. This is to reduce the contact friction of the leg frames 2b, 2b against the inner surfaces of the front plate portion 1a and the back plate portion 1b in the base block 1, that is, ascending / descending operation based on linear contact by the linear slider 2c. This is intended to facilitate smoothing. This may be configured to reduce friction by other means.

  Reference numeral 3 denotes a plate-like float formed of a plastic material having single bubbles, and is stretched between the above-mentioned leg-shaped frames 2b and 2b. And the said float 3 is comprised so that it may raise with the buoyancy by water entering the base | substrate block 1 which exhibits the groove shape mentioned above.

  4 is a pipe material having elasticity, and when a plurality of water shielding panels A are provided continuously in the lateral direction, they are interposed between the respective water shielding panels A to fill the gaps and interlock with each other. It is responsible for the intervening material for interlocking so that it can be lifted and lowered.

By the way, the above-described base block 1 has one side surface (for example, the front plate portion 1a) facing the overflow side (the side from which water is pushed), and the other side surface (for example, the back plate portion 1a) is directed to the overflow prevention side (house or the like). Buried toward the side. And while flowing water is received from the clearance gap M formed in the upper edge of the said one side surface, the clearance gap N of the other side uses a rubber band B etc., and is elastically in the state which does not prevent the raising / lowering of the panel A for water shielding. By closing, water is not leaked from the gap N. (See FIGS. 4 and 5).
The means for preventing water from leaking from the gap N may be other appropriate means instead of the rubber band B.

  As shown in FIG. 6, the present invention having the above-described configuration is installed in front of a house, in front of any other object to be protected such as a building, a condominium, an underground passage, a road, or a required place. Then, by keeping the water shielding panel A in the grooved base block 1 (the lowered state), the obstruction during normal operation is avoided.

  And when water has come near by heavy rain, flood, tsunami, etc., since flowing water is received from the clearance gap M, the base | substrate block 1 is filled with water. Then, the gap N on the other side is from the gap N by using rubber band B or the like to close in a state that does not hinder the raising and lowering of the water shielding panel A, that is, by elastically contacting and closing. It is configured to prevent water discharge.

  Therefore, buoyancy is imparted to the plate-like float 3 based on the storage of water in the base block 1, the entire water shielding panel A is raised, and the overflow preventing action by the water shielding panel is achieved. FIG. 5 shows the overflow prevention state, and normally the water flow prevention action up to the height of H shown in FIG. Will be.

  When water is pulled, the water shielding panel A is automatically restored by its own weight. Further, if there is excess water, the water shielding panel A can be completely restored to its original state by removing it using a pump or the like.

  In the present invention, it is possible to form a flood prevention wall having a required length by using a unit for the water shielding panel A as one unit and connecting a plurality of units in a lateral direction as necessary. The
