Description

Parking lot flood prevention device {APPARATUS FOR FLOOD PROTECTION IN PARKING LOT}

This disclosure relates to a parking lot flood prevention device.

Generally, facilities such as parking lots for vehicle parking are provided underground in buildings such as residential-commercial complexes or high-rise apartments. An entrance is provided on the ground to access the underground parking lot, and a ramp leads from the entrance to the underground parking lot. Entrances are usually formed so that the height of the floor is the same as the ground so that users can enter and exit conveniently.

Accordingly, when heavy rain occurs during the rainy season or due to a typhoon, rainwater flows over the floor of the underground entrance and into the basement, such as a parking lot, and floods underground facilities. This can result in property damage as well as casualties, so preparation for this is urgently needed.

In the conventional case, sandbags were piled up in advance at the entrance leading to the underground parking lot, or a water barrier was erected to prevent the inflow of rainwater.

The flood blocking structure using a water stopper is a structure in which a support frame is installed on both walls of the entrance, a water stopper that moves up and down is provided inside the support frame, and the water stopper plate moves up and down to block the space between the walls.

However, all of the above-mentioned conventional structures have a problem in that the space between the walls of the entrance is blocked by standing vertically with sandbags or water barriers, and once the space between the walls is blocked, no vehicle can enter or exit.

Accordingly, when vehicle access is required, such as in an emergency situation, there is a problem in that the water barrier must be lowered again, and in this process, rainwater blocked by the water barrier can flow into the basement at once, causing a major problem.

This project is to provide a parking lot flood prevention device with a raised water barrier that blocks the inflow of rainwater and allows vehicles to enter and exit when necessary.

This project is to provide a parking lot flood prevention device that can raise the water barrier using buoyancy.

This project is to provide a parking lot flood prevention device that can minimize water inflow.

The flood blocking device of this embodiment includes a guide frame installed on both walls facing the entrance, a water blocking plate installed to be movable up and down along the guide frame and blocking the inflow of rainwater by blocking between the walls, and between the guide frames. A water tank installed below the ground to store water flowing in from the outside, a buoyancy body installed at the bottom of the water cutoff plate and located within the water tank to float on the water surface by buoyancy to raise and lower the water cutoff plate, and an entrance on the water cutoff plate. They are arranged in each direction in the entrance and exit direction, and one end is rotatably installed on the water stopper, and the other end extends in the entrance and exit direction of the entrance and is lowered to the ground, forming an inclined surface between the ground and the top of the water stopper as the water stopper rises. It may include a pair of inclined plates.

It may further include a horizontal plate installed parallel to the ground on the top of the water stop plate and extending in the entrance/exit direction, and on both ends of which the inclined plate is rotatably installed.

It may further include a groove member installed on the ground near the entrance and provided with a groove portion that is stepped from the ground so that the inclined plate is seated.

The guide frame has a guide groove formed on its inner side to support the tip of the water stopper and guide it up and down, and a seal member that seals the space between the water stopper and the waterstop may be installed on the inside of the guide groove.

It may further include a guide roller installed at the tip of the water stopper plate inserted into the guide groove of the guide frame to prevent friction with the guide groove.

The water tank may include an inlet pipe installed on one side to allow external water to flow in, a discharge pipe to discharge internal water to the outside, and a discharge valve installed in the discharge pipe to selectively open and close the discharge pipe.

It may further include a discharge pump installed in the discharge pipe to discharge water.

The flooding blocking device may further include a water supply unit.

The water supply unit includes a supply pipe connected to an inflow pipe formed in the water tank, a supply pump installed in the supply pipe to supply water from a water supply source to the water tank, an opening/closing valve installed in the inflow pipe, and a supply pump for controlling and driving the opening/closing valve. It may further include a control unit to forcibly supply water to the water tank in addition to rainwater.

The flooding blocking device is installed on one side of the water tank and includes a detection sensor that detects the rise of the buoyant body, a control unit that calculates the detection signal of the detection sensor, and a warning unit that externally displays the rise of the buoyant body according to the output signal of the control unit. More may be included.

According to this embodiment, even in a state where rainwater is blocked by the water barrier, a vehicle can enter and exit smoothly using the inclined plate connected to the water barrier.

When necessary, the vehicle can be moved without lowering the water barrier, and rainwater can be prevented from flowing into the basement when the vehicle is moving.

By elevating the water stopper using buoyancy, the device can be driven with less energy and the water stopper can be raised more quickly to minimize the inflow of rainwater.

The water barrier can rise and fall smoothly while maintaining airtightness due to external water pressure, effectively preventing the inflow of rainwater.

Hereinafter, this embodiment will be described as an example of a structure installed at the entrance of an underground parking lot to block rainwater flowing into the underground parking lot through the entrance. The present invention can be installed at the entrance side of the ground to all facilities provided underground in addition to the underground parking lot.

Figure 1 shows a flood prevention device installed at the entrance of a parking lot according to this embodiment, and Figure 2 shows the configuration of the flood prevention device according to this embodiment.

In the following description, the y-axis direction of FIG. 1 is referred to as the up-down direction or vertical direction, the upper direction along the y-axis direction is referred to as the upper, upper, and upper direction, and the opposite downward direction is referred to as the lower, lower, and lower direction. Additionally, in Figure 1, the x-axis direction is referred to as the entry/exit direction in which the vehicle moves, and the z-axis direction is referred to as the width direction.

An entrance 100 is provided on the ground along the passage leading to the underground parking lot. The flood prevention device of this embodiment is installed at the entrance 100 and has a structure to block rainwater flowing into the underground parking lot from the outside of the entrance 100 through the entrance 100.

To this end, the flood prevention device of this embodiment includes a water stopper plate 10 that blocks rainwater, a guide frame 20 that supports the water stopper plate 10, a water tank 30 for holding water, and a water stopper plate 10. It may include a buoyancy body 40 to raise the vehicle, and an inclined plate 50 for vehicle movement.

The guide frame 20 is provided in pairs and is installed vertically on both walls facing each other of the entrance 100. A water stopper plate (10) is installed between the two guide frames (20). The guide frame 20 supports the water stopper 10 and guides it up and down.

As shown in FIG. 3, each guide frame 20 supports the side ends of the water stopper plate 10 on surfaces facing each other and has a guide groove 22 for guiding the water stopper plate 10 when moving up and down in a vertical direction. It is formed by extending along.

A seal member 24 may be installed inside the guide groove 22 to seal the space between the guide groove 22 and the water stopper plate 10. The seal member 24 extends along a direction perpendicular to the guide groove 22. The seal member 24 may be installed on one of the three sides of the guide groove 22 where the water stopper plate 10 is pushed out by the water pressure caused by rainwater. That is, the seal member 24 may be installed on the inner surface of the guide groove 22 facing outward from the entrance 100 along the entrance/exit direction.

Accordingly, the water stopper plate 10 is pushed by the water pressure of rainwater applied from the outside of the entrance 100, and may come into close contact with the seal member 24 installed in the guide groove 22. Accordingly, the gap between the guide groove 22 and the water stopper plate 10 is blocked by the seal member 24, thereby effectively preventing the inflow of rainwater.

It is sufficient for the seal member 24 to be in close contact with the water stopper plate 10 to block the gap, and its shape and material can be modified in various ways.

The water stopper plate 10 is a plate structure extending in the width direction and stands vertically to block the inflow of rainwater. The water stopper plate 10 is installed so that both side ends are inserted into the guide grooves 22 of the guide frame 20 and can move up and down along the guide frame 20.

As the water stopper plate 10 rises and stands vertically between the walls of the entrance 100, rainwater can be prevented from flowing into the basement.

As shown in FIG. 3, guide rollers 12 may be installed on both sides of the water stopper plate 10 so that they can move smoothly along the guide grooves 22 of the guide frame 20. The guide roller rotates freely as the water stopper plate 10 rises and falls to prevent friction between the guide groove 22 and the water stopper plate 10.

For example, the guide roller 12 may be installed on each side of the water stopper plate 10 facing the three sides of the guide groove 22, which is not in contact with the seal member 24. Accordingly, the water stopper plate 10 can move smoothly up and down along the guide groove 22 by the guide roller 12 without interfering with the seal member 24.

A buoyancy body 40 is installed at the bottom of the water stopper plate 10. In addition, a water tank 30 in which the buoyancy body 40 is located is provided below the ground level of the entrance 100.

The water tank 30 is installed below the ground between the guide frames 20 and can store water flowing in from the outside.

The buoyancy body 40 is installed at the bottom of the water stopper plate 10 and is located in the water tank 30, so that it floats on the water surface by buoyancy and raises and lowers the water stopper plate 10. The buoyancy body 40 is made of a material or structure that can float in water. The size or structure of the buoyancy body 40 may be modified in various ways depending on the buoyancy force applied by the load such as the cutoff plate 10 and the inclined plate 50 to be lifted.

As the water level in the water tank 30 rises, the buoyancy body 40 floats on the water surface by buoyancy and lifts the water stopper plate 10. Due to the buoyancy of the buoyancy body 40, the cutoff plate 10 and the inclined plate 50 can stably maintain their elevated state.

The buoyancy body 40 may have a structure that can only support the load of the water cutoff plate 10 and the sloping plate 50. In this structure, when the vehicle passes the inclined plate 50, the buoyancy body 40 may descend due to being pressed by the weight of the vehicle. A swash plate 50 is installed on the water stop plate 10, so that a vehicle can easily pass through the water stop plate 10 through the swash plate 50 when the water stop plate 10 is raised.

The water stopper 10 is temporarily pressed and lowered when a vehicle passes, and then quickly rises again due to the buoyancy of the buoyancy body 40 after the vehicle passes, allowing it to return to its original state. Accordingly, the inflow of rainwater can be minimized.

In another embodiment, the buoyancy body 40 may be a structure that supports the load of the vehicle. In the case of this structure, the buoyancy body 40 can stably maintain an elevated state while supporting the load applied as the vehicle passes. Accordingly, the vehicle can easily pass through the water stopper 10 along the inclined plate 50 while the water stopper 10 is raised to block the inflow of rainwater.

The water tank 30 forms a space inside which water can be stored. The size of the water tank 30 may vary depending on the shape or size of the buoyancy body 40.

As shown in Figure 2, the water tank 30 is installed on one side and is installed in an inlet pipe 31 through which external water flows in, an outlet pipe 32 for discharging the internal water to the outside, and an outlet pipe 32. It may include a discharge valve 34 that selectively opens and closes the discharge pipe 32.

The inflow pipe 31 is a pipe through which external rainwater, etc. flows into the water tank 30. The inlet pipe 31 may be connected to, for example, a sewer on a road through which rainwater flows. Accordingly, rainwater flowing into the sewer may flow into the water tank 30 through the inflow pipe 31. The water tank 30 is located sufficiently below the ground, so that rainwater flowing into the road drain can smoothly flow into the water tank 30 located lower.

The discharge pipe 32 discharges and removes rainwater filled in the water tank 30 when necessary. By opening and closing the discharge valve 34, rainwater contained in the water tank 30 can be discharged to the outside. As the water in the water tank 30 is discharged through the discharge pipe 32, the water level decreases and the water stopper plate 10 installed on the buoyancy body 40 moves downward.

In order to more quickly discharge water in the water tank 30, a discharge pump 35 may be further installed in the discharge pipe 32.

The flooding blocking device of this embodiment may further include a water supply unit.

The water supply unit includes a supply pipe 36 connected to the inflow pipe 31 formed in the water tank 30, a supply pump 37 installed in the supply pipe 36 to supply water from the water supply source to the water tank 30, and an inflow pipe. It may have a structure that forcibly supplies water to the water tank 30 in addition to rainwater, further including an on-off valve 33 installed in (31) and a control unit 60 for controlling and driving the on-off valve 33.

For example, the water supply source may be a structure that supplies water through a water pipe.

Accordingly, when necessary, when the supply pump 37 is driven and the opening/closing valve 33 installed on the supply pipe 36 is opened and operated, water is supplied to the water tank 30 through the inflow pipe 31 connected to the supply pipe 36. .

Therefore, by forcibly supplying water into the water tank 30 separately from the rainwater naturally flowing into the water tank 30 through the inlet pipe 31, the water stopper plate 10 can be driven upward more quickly.

In this way, water in addition to rainwater can be forcibly supplied into the water tank 30, so when a large amount of heavy rain pours and the water stopper 10 needs to be raised quickly to block rainwater, the water stopper 10 is raised more quickly. It is possible to effectively prevent rainwater from entering the basement.

In addition, the flooding blocking device of this embodiment is installed on one side of the water tank 30 and includes a detection sensor 62 that detects the rise of the buoyancy body 40, a control unit 60 that calculates the detection signal of the detection sensor 62, and a control unit. It may further include a warning unit 64 for externally displaying the rise of the buoyancy body 40 according to the output signal of (60).

It is sufficient for the detection sensor 62 to detect the rise of the buoyant body 40 within the water tank 30, and various sensors can be used.

For example, the warning unit 64 may have a structure that externally displays a visual warning sign, including a warning light, or an auditory sound, such as a siren.

The control unit 60 can operate the warning unit 64 by calculating the detection signal applied from the detection sensor 62 and applying an output signal to the warning unit 64 when necessary. In addition, the control unit 60 is connected to the on-off valve 33 installed in the inlet pipe 31, the discharge valve 34 installed in the discharge pipe 32, the supply pump 37, and the discharge pump 35 to drive these components. can be controlled.

As the control unit 60 is driven, water fills the water tank 30, causing the buoyancy body 40 to float on the water surface, and as the water level in the water tank 30 rises, the water stopper plate 10 installed on the buoyancy body 40 It rises above the ground and blocks the entrance 100.

As the water stop plate 10 is raised, the inclined plate 50 installed on the water stop plate 10 is lifted together to form a ramp along the entrance/exit direction. Accordingly, in a state where the water stop plate 10 blocks the entrance 100, the vehicle can enter and exit along the inclined plate 50 without lowering the water stop plate 10 again. That is, when a vehicle passes by and reaches the inclined plate 50, the buoyancy body 40 descends according to the load of the vehicle applied to the inclined plate 50 and the water stop plate 10 is lowered. That is, when the vehicle passes the inclined plate 50, the buoyancy body 40 moves down due to the load applied to the water stop plate 10 through the inclined plate 50, causing the water stop plate 10 to descend. Accordingly, the vehicle is able to pass the water stop plate 10 lowered along the inclined plate 50.

Even when the buoyancy body 40 can support the load of the vehicle, the vehicle can smoothly pass the water stop plate 10 along the inclined plate 50 with the water stop plate 10 raised. Accordingly, in any case, the vehicle can smoothly pass through the water cutoff plate 10 along the inclined plate 50.

In this embodiment, a horizontal plate 52 may be further installed on the top of the water stop plate 10 so that a vehicle can pass smoothly while the water stop plate 10 is raised. The two inclined plates 50 may be axially coupled to both ends of the horizontal plate 52 and rotatably installed.

The horizontal plate 52 is a flat plate structure extending toward the entrance and exit, and can be installed on the top of the water cutoff plate 10 while being horizontal with the ground. The size of the horizontal plate 52 can be varied in various ways.

The horizontal plate 52 is located between the two inclined plates 50 to form a horizontal surface between the two inclined plates 50. Accordingly, a sharp attachment does not appear between the two swash plates 50 and becomes flat by the horizontal plate 52, allowing the vehicle to pass between the two swash plates 50 stably without interference.

The inclined plate 50 may be a flat plate structure. Two inclined plates 50 may be formed as a pair and disposed on the outside and inside of the entrance 100 along the entrance/exit direction with the water cutoff plate 10 in between. Each inclined plate 50 has one end rotatably installed on the horizontal plate 52, and the other end forms a free end and extends in the entrance/exit direction of the entrance 100.

Accordingly, as the water stop plate 10 rises, one end of the inclined plate 50 connected to the horizontal plate 52 is lifted, forming an inclined surface by the inclined plate 50 between the ground and the top of the water stop plate 10. There will be. Accordingly, in a state in which the water stopper plate 10 is raised to block rainwater, the inclined plate 50 is placed at an angle between the water stopper plate 10 and the ground, so that vehicles, etc. can smoothly pass over the water stopper plate 10 through the inclined plate 50. It becomes possible.

For example, the length of each inclined plate 50 in the entry/exit direction may be such that when the water stop plate 10 is raised to form an inclined surface, a vehicle, etc. can move along the inclined surface.

Additionally, a groove member 54 on which the inclined plate 50 is placed may be installed on the ground near the entrance 100. A groove 56 in which the swash plate 50 is placed may be formed on the upper surface of the groove member 54 at a height corresponding to the thickness of the swash plate 50.

Accordingly, as the water stop plate 10 descends, the swash plate 50 is seated in the groove portion 56 of the groove member 54, so that the ground and the swash plate 50 are at the same height. Accordingly, in a state where the water stop plate 10 is not used, there is no height difference between the swash plate 50 and the ground, allowing vehicles, etc. to pass the swash plate 50 smoothly.

Figure 4 shows the use state of the rainwater blocking device according to this embodiment.

As shown in FIG. 4, when rainwater flows into the water tank 30 due to heavy rain, etc., the water level inside the water tank 30 increases and the buoyancy body 40 floats on the water surface due to buoyancy, and thus the buoyancy body The water stopper plate 10 installed at (40) is raised upward.

The water stopper plate 10 extends upward from the ground along the guide groove 22 of the guide frame 20 to block rainwater. Accordingly, rainwater outside the entrance 100 can be prevented from flowing into the entrance 100 by being blocked by the vertically standing water blocking plate 10.

As the water stopper plate 10 rises vertically, the horizontal plate 52 installed on the waterstop plate 10 rises, and one end of the inclined plate 50 axially coupled to the horizontal plate 52 is pulled upward together. do.

Accordingly, the inclined plate 50 is disposed at an angle between the horizontal plate 52 at the top of the water stop plate 10 and the ground on both sides of the entrance 100. That is, in a state where the water stopper plate 10 is erected vertically to block rainwater, the inclined plate 50 is placed at an angle on the ground on both sides of the water stopper plate 10. Accordingly, vehicles, etc. can pass by using the inclined plate 50 without lowering the water stop plate 10 to open the entrance 100.

In this way, vehicles, etc. can enter and exit even after raising the water barrier 10, so there is no need to lower the water barrier 10 to exit the vehicle in an emergency situation, and it is possible to prevent rainwater from flowing into the basement during the vehicle movement process. You can.
