KR20260067255AKR 20260067255 AKR20260067255 AKR 20260067255AKR-20260067255-A

Abstract

The present invention relates to a mechanical flood warning and escape route providing device that enables a driver to recognize flooding in advance and safely escape in an emergency during a flooded underpass. This device operates without electricity and is installed extending from the floor of the underpass to the upper road, having a structure in which a buoy and a hole are formed in a hollow rectangular pipe. When water flows in, the buoy rises to provide a visual warning via a flag (102) located on the outside, and the pipe hole serves as a stepping stool during escape. The present invention is effective in preventing flooding accidents and protecting lives within underpasses by reliably warning of flooding conditions even in environments where power supply is difficult and by providing a safe escape route to the driver.

Claims (5)

  1. A flood warning and escape route providing device having the function of visually notifying a driver of flooding in a flooded underpass and capable of functioning as an emergency escape route in the event of flooding, comprising a hollow rectangular pipe, wherein one side of the pipe is fixed to the wall of the underpass, and the remaining three sides have holes formed at regular intervals to serve as stepping stones.
  2. A flood alarm and escape route providing device according to claim 1, characterized in that the holes are formed in a size that allows a person to easily step on them, and the spacing between the holes is set so that they can be safely used by a wide range of age groups, from elementary school students to adults.
  3. A flood warning and escape route providing device according to claim 1, wherein a buoy capable of rising by buoyancy is located inside the pipe, and the buoy rises upon the inflow of water to raise a flag located outside the pipe together.
  4. A flood warning and escape route providing device according to claim 3, wherein the flag is set to an optimal height considering the depth of the underpass and the distance from the lane, and a notification plate with a scale is additionally attached to the back of the flag to visually display the flood level according to the position of the flag.
  5. A flood warning and escape route providing device according to claim 1, characterized in that the hole of the pipe includes a filter to prevent foreign matter from entering and blocking the hole, or a sloped structure to facilitate the discharge of foreign matter, so that the hole is designed to maintain its function as a footrest.

Description

Underpass Flood Warning and Escape Route The present invention belongs to the field of disaster preparedness and road safety devices, and in particular relates to a mechanical warning and escape device that enables a vehicle driver to recognize a flooding situation in advance and safely escape in an emergency situation in a low-lying area, such as an underpass, which is likely to be flooded due to natural disasters. This device is a mechanical device designed to operate independently even in environments where power supply is difficult, and is configured to visually indicate whether flooding has occurred so that the driver can identify the risk of flooding in advance, and to be used as an escape route when necessary. The technology underlying this invention aims to prevent flooding accidents that may occur in low-lying areas, such as underpasses, due to heavy rainfall, and to provide a structure that allows for safe evacuation in the event of flooding. Previously, electronic warning systems or physical barriers were used to prevent accidents in flood-risk areas. Electronic warning systems utilize electronic components, such as water level sensors, to detect flooding and provide warning signals; however, these systems have limitations in maintenance and reliability in areas where power supply is difficult or where they must remain on standby for extended periods. In particular, in locations with unreliable power supply, such as underpasses, it is difficult to install and operate electronic systems, making it hard to expect practical effectiveness. Meanwhile, physical barriers are used to prevent accidents by physically blocking vehicle entry in the event of flooding. However, these barriers can only operate after flooding has occurred, which has the disadvantage that it is difficult for drivers to recognize flooding in advance. In addition, physical barriers have the limitation of merely blocking vehicles and failing to provide an emergency evacuation route in the event that a driver enters. To compensate for these limitations of existing technology, the present invention operates mechanically without a power supply to provide a reliable flood notification function even in a standby state for a long time, and is configured so that the warning device functions as an escape route in the event of a flood. [Fig. 1] Operating principle of the underpass flood warning system [Fig. 2] Specific shape of the underpass flood warning system [Fig. 3] Before and after operation of the underpass flood warning system The present invention consists of a mechanical flood alert and escape route providing device that allows a driver to recognize flooding in advance in the event of flooding in an underpass and to use it as an emergency escape route in case of emergency. The device operates 100% mechanically without electricity and is installed at the entrance of the underpass. Specific embodiments of the present invention are described as follows. The core element of the present invention consists of a hollow rectangular pipe (100), which is installed long from the floor of the underpass to the upper road. The length of one side of the pipe (100) is appropriately set between 50 cm and 70 cm by referring to the width of a standard ladder, considering the safe and convenient ascent and descent of the escapee. Such a sufficiently wide width provides a sense of stability when a person ascends and descends, and is effective as a width that allows multiple people to use it simultaneously in an emergency situation. One side of this rectangular pipe (100) is fixed to the wall of the underpass, and holes (101) are drilled at regular intervals on the remaining three sides so that an escapee can step on them and climb up. Each hole (101) is designed with a size and spacing that is convenient for the user to step on, and is designed to accommodate not only adult feet but also the feet of elementary school students in lower grades. Specifically, the size of the hole (101) is set to a size that can stably support the foot, and is carefully adjusted so that it can be used quickly and safely even in emergency situations. The spacing of the hole (101) is also appropriately set so that everyone from elementary school students to older adults can safely place their feet on it, and is not too wide to prevent instability. The spacing of the hole (101) is set to a size that allows even a young child in the first grade of elementary school to easily place their feet on it, and the spacing of the footrests is designed not to be wide, allowing users of various age groups to use it for escape. The spacing and size of the holes (101) are adjusted so that all users can safely move up and down, facilitating rapid evacuation in emergency situations. Additionally, to prevent foreign matter from entering and blocking the holes (101) during flooding, a foreign matter inflow prevention filter is installed in the holes (101), or a slope is applied to the structur
