Description

{WATER INFLOW BLOCKING EQUIPMENT OF THE UNDERGROUND PARKING LOT}

The present invention relates to a device for blocking rainwater inflow into an underground parking lot. More specifically, it automatically closes the entrance to the underground parking lot in conjunction with a water level sensor, so that when rainwater flows into the underground parking lot due to heavy rain, etc., the rainwater inflow is quickly and completely. This relates to a device that blocks rainwater inflow from an underground parking lot.

Typically, residential spaces such as apartments and residential-commercial complexes, and office spaces such as buildings, have single- or multiple-story underground parking lots in the basement to suit the residents' vehicle ownership.

Recently, due to environmental problems such as global warming, heavy rains are occurring frequently regardless of the season. When heavy rains occur as described above, the underground spaces of buildings located in low areas are quickly overflowed with rainwater and cannot be drained. Unclean rainwater flows into the internal parking space through the entrance, causing enormous property damage and casualties.

In other words, when heavy rain occurs and a large amount of rain flows to the floor, the rainwater flows through the entrance of the underground parking lot and along the sloped access road. In the case of a small amount of rainwater flowing into the underground parking lot, it is drained through the drain, but in a momentary large amount. When rainwater flows in, flooding occurs in the underground parking lot, and at this time, it is forcibly drained through a separately prepared drainage pump. At this time, when heavy rain continues for a long time, the amount inflow is greater than the amount discharged through the drainage pump, so there is a problem that the vehicle is eventually flooded, and when flooded, not only vehicles but also various electrical equipment installed in underground structures are flooded.

To solve this problem, a “rainwater inflow prevention device” has been proposed in Patent Publication No. 10-2012-0122504, and a “water-water inflow prevention device” has been proposed in Patent Publication No. 10-2013-0112355.

However, the above-described technology is a technology that simply prevents water from flowing in by attaching a water cutoff plate to the location where water flows in. Although it has the advantage of a simple structure, the water cutoff plate must be closely adhered and fixed during installation, preventing water from flowing in. There is a problem that it is difficult to install in this condition, and there is a problem that the watertightness of the water barrier plate is reduced during installation.

Hereinafter, the device for blocking rainwater inflow in an underground parking lot of the present invention will be described in more detail with reference to preferred embodiments and the accompanying drawings. In this regard, Figure 1 is a perspective view of the entrance to an underground parking lot where an underground parking lot rainwater inflow blocking device according to the present invention is installed, Figure 2 is a system configuration diagram for each device constituting the parking lot rainwater inflow blocking device, and Figure 3 is a This is a perspective view of the water blocking shutter and guide channel among the rainwater inflow blocking devices in the parking lot, and Figure 4 is a side cross-sectional view of the rainwater inflow blocking device in the underground parking lot.

Referring to Figures 1 to 4, the underground parking lot rainwater inflow blocking device 1000 of the present invention largely includes a water shutter 100, a guide channel 200, a winding unit 300, and a control unit 400. It can be configured to include.

The water blocking shutter 100 is a device for blocking the inflow of rainwater by opening and closing the entrance and exit of the underground parking lot in the vertical direction and closing the entrance when rainwater flows in.

The guide channels 200 are provided in pairs on both walls of the entrance to the underground parking lot, and are inserted into both ends of the water shutter 100 to guide the raising and lowering of the water shutter 100.

The winding unit 300 is a device provided on the upper part of the guide channel 200 to raise and lower the order shutter 100 in a winding manner, and the control unit 400 operates the winding unit 300. It is a device for control.

In the present invention, the order shutter 100 may be configured to include a plurality of order panels 110, each of which has both ends inserted into the pair of guide channels 200. At this time, the plurality of order panels 110 may be configured to be hinged and rotatable to each other.

Accordingly, the upper and lower ends of the plurality of water blocking panels 110 are hinged to each other, so that they are wound upward in a roll shape by the winding unit 300 in normal times to keep the entrance open, and are lowered in case of rainwater flooding. By combining and unfolding into a plate shape, the entrance is closed.

In this way, in the present invention, as the water shutoff shutter 100 is deployed from the top to the bottom, the water shutoff shutter 100 can be stably deployed without being relatively affected by the flow rate of the inflow water even when the flow rate of the inflow water is high.

Hereinafter, each order panel 110 will be described in more detail with reference to FIGS. 5 and 6 . In this regard, FIG. 5 is a perspective view of an order panel 110 according to one embodiment of the present invention, and FIG. 6 is a perspective view of an order panel 110 according to another embodiment of the present invention.

First, referring to FIG. 5, each order panel 110 may be formed in the shape of a horizontal rectangular plate with both ends inserted into the guide channel 200. At this time, a protrusion 111 that extends and protrudes in a trapezoidal shape may be formed on the upper surface, and a concave portion 112 that is recessed and recessed in a shape corresponding to the protrusion 111 may be formed on the bottom surface. In addition, a hinge portion 120 that enables rotation between the order panels 110 that are coupled to each other may be provided on one side of the coupling surface of the order panels 110 adjacent to each other.

By this, the protrusion 111 is inserted into the concave portion 112 of the order panel 110 coupled to the upper side, and the concave part 112 is the protrusion 111 of the order panel 110 coupled to the lower side. By being inserted and combined with each other, the entire water blocking shutter 100 forms a water blocking wall to block the inflow of rain water into the inside of the underground parking lot.

On the other hand, a slight gap is formed at the joint surface between the water blocking panel 110 and the water collection panel 110, and when high water pressure is applied over a long period of time, there is a risk that rainwater will flow into the inside of the underground parking lot through this gap. .

Therefore, according to the present invention, in order to strengthen the watertightness of the above joint surface, a protrusion rubber pad 130 is attached to the upper surface of the protrusion 111, as shown in FIG. 6, and a protrusion rubber pad 130 is attached to the upper surface of the concave portion 112. A concave rubber pad 140 may be attached.

As a result, the elasticity of the rubber pad prevents gaps in the joint surface, thereby preventing rainwater from flowing into the underground parking lot even during long-term rainwater flooding. At this time, according to the present invention, at least one of the protruding rubber pad 130 and the recessed rubber pad 140 includes a magnetic material so that the protruding rubber pad 130 and the recessed rubber pad 140 are bonded by magnetic force. By doing so, the watertightness of the joint surface can be further strengthened.

That is, the protruding rubber pad 130 and the recessed rubber pad 140 may be provided with magnetic materials so that different polarities are oriented, and one of the protruding rubber pad 130 and the recessed rubber pad 140 may be provided with a magnetic material. One may be provided with a magnetic body, and the other may be provided with a metal material attached to the magnetic body.

In the present invention, the winding unit 300 includes a winding roller 310 configured in the form of a horizontal rod or drum so that the upper end of the order shutter 100 is fixed and wound, and the winding roller 310 is wound on the winding roller 310. It may be configured to include a shielding case 320 that accommodates the shutter 100 and shields it from the outside, and a drive motor 330 that rotates the winding roller 310. The driving motor 330 may be driven by the control unit 400 described above.

Meanwhile, a water level sensor 410 may be installed on one side of the guide channel 200 to detect the water level of the inflow water flowing into the parking lot entrance. Accordingly, the control unit 400 operates in conjunction with the water level sensor 410 to lower the order shutter 100 when the inflow water is detected through the water level sensor 410. 330) is activated.

Accordingly, according to the present invention, the order shutter 100 wound in a roll form on the upper part of the entrance to the underground parking lot is immediately lowered by the driving force of the drive motor 330 in conjunction with the water level sensor 410, thereby preventing heavy rain. It is possible to quickly block the inflow of rainwater.

At this time, the water level sensor 410 is installed at a predetermined height upward from the floor, and the height can be installed to be adjustable in the range of 5 to 10 cm. If the height is too low, there is a risk that the water shutoff shutter 100 may be blocked even when it is not an emergency. If it is too high, there is a problem that the inflow of rainwater cannot be blocked in a timely manner, so it must be properly adjusted according to surrounding conditions and rainfall conditions. It can be installed to adjust the height.

Additionally, the control unit 400 may be configured to switch to a manual mode in which the winding unit 300 is driven by user manipulation. Accordingly, according to the present invention, even when electric equipment is turned off due to flooding, it is possible to block the inflow of rainwater by manually lowering the water shutoff shutter 100.

Meanwhile, some space is inevitably formed between the inside of the guide channel 200, where both ends of the order shutter 100 are inserted and raised and lowered, and both ends of the order shutter 100. High water pressure acts or rapid If influent water flows in at a high flow rate, there is a risk that rainwater may flow into the underground parking lot through these spaces.

Therefore, in order to solve this problem, the present invention, as shown in FIG. 7, has a rear surface of the water blocking panel 110 and a guide channel 200 on the rear surface of both ends of the water blocking panel 110 inserted into the guide channel 200. An inner rubber pad 210 is provided to strengthen the watertightness of the joint surface with the inner surface.

Accordingly, when the water shutoff shutter 100 is lowered, rainwater flowing in from the outside of the water shutoff shutter 100 presses the water shutoff shutter 100 inward due to water pressure, and at this time, the water shutoff panel is compressed by the elasticity of the inner rubber pad 210. (110) The back surface and the inner surface of the guide channel 200 come into close contact, thereby preventing rainwater from leaking between the inner side of the guide channel 200 and both ends of the water shutter 100.

According to one embodiment of the present invention, when the guide channel 200 is made of a metal material, the inner rubber pad 210 may be configured to include a magnetic material to adhere to the inner surface of the guide channel 200, which is a metal material, by magnetic force. . In the case of this embodiment, the back of the order panel 110 and the inner surface of the guide channel 200 are brought into close contact by magnetic force even without an external force acting on the outside of the order shutter 100, so the back of the order panel 110 and the guide channel 200 ) It is possible to secure watertightness between the inner surfaces.

Furthermore, after the rear surface of the water blocking panel 110 and the inner side of the guide channel 200 are attached, the water pressure generated in the water shutter 100 is applied to the rear surface of the water blocking panel 110 and the inner surface of the guide channel 200. Make it adhere more closely to.

Meanwhile, in this case, when the order panel 110 moves downward, the back of the order panel 110 is attached to the inner surface of the guide channel 200 by magnetic force, which may cause a problem in which the descent of the order panel 110 is hindered. You can.

In order to solve this problem, according to another embodiment of the present invention, the guide channel 200 is rotatably provided on one side of the outer end of the guide channel 200 to selectively adhere to the back of the guide channel 200 and Close contact guide pieces 220 configured in a form that allows separation may be provided.

In this embodiment, the guide channel 200 is made of a non-magnetic material such as aluminum. Additionally, the inner rubber pad 210 may be made of a metal material or a magnetic material. In this case, the close contact guide piece 220 may be made of a magnetic material if the inner rubber pad 210 is composed of a metal material, and may be made of a metallic material if the inner rubber pad 210 is composed of a magnetic material. You can.

In this case, when the order shutter 100 is lowered, the close guide piece 220 is spaced apart from the back of the guide channel 200 so that the order shutter 100 contacts the guide channel 200 by magnetic force and does not interfere with the descent of the order shutter 100. After the lowering of the order shutter 100 is completed, the inner rubber pad 210 is in close contact with the inner surface of the guide channel 200 by magnetic force while in close contact with the back of the guide channel 200. , it is possible to secure watertightness between the rear surface of the water blocking panel 110 and the inner surface of the guide channel 200.

At this time, the magnetic material provided in the protruding rubber pad 130 and the recessed rubber pad 140 generates a repulsive force to separate them from each other by the magnetic material of the close contact guide piece 220, so that the order panel 110 is connected to the guide channel ( 200) It may interfere with adhesion to the inside.

Therefore, in the present invention, in order to prevent this, the magnetic material provided in the protruding rubber pad 130 and the recessed rubber pad 140 is provided in the rubber pad area excluding the area inserted into the guide channel 200, It is possible to prevent interference between the magnetic material of the concave rubber pads 130 and 140 and the magnetic material of the close contact guide piece 220.

Although the preferred embodiments of the present invention have been described above, those skilled in the art can add, change, delete or add components without departing from the spirit of the present invention as set forth in the patent claims. The present invention may be modified and changed in various ways, and this will also be included within the scope of rights of the present invention.
