Abstract
Description
Lifting type water cutoff device
[0001] The present invention relates to a lifting type water barrier, and more specifically, to a lifting type water barrier that improves a water barrier designed to prevent rainwater from overflowing and entering an indoor space by adopting a self-lifting structure of the barrier plate instead of a separate traction method, thereby allowing for simple installation at an entrance or exit where people or vehicles pass, so that it is positioned above the entrance to secure the entrance during normal times, and can block the entrance in an emergency.
[0002] Generally, water barriers are installed at building entrances in low-lying areas, underpasses used by vehicles, and entrances to underground parking ramps by simply installing or removing water barrier plates to minimize the inflow of floodwaters during rainfall and subsequent inundation.
[0003] Normally, the water barrier and related posts are stored in a location close to the entrance, and in an emergency such as a warning of flooding due to rainfall, the stored water barrier is transported and installed from the ground by workers one by one, or dismantled when the emergency is lifted.
[0004] Alternatively, when examining prior art technologies that allow the water barrier to be raised and lowered to block the entrance, thereby eliminating the need to store the water barrier separately, Registered Patent No. 10-1698460 (Title: Motor-driven water barrier device, hereinafter referred to as 'Patent Document 1') and Registered Patent No. 10-2598076 (Title: Shutter-type water barrier device, hereinafter referred to as 'Patent Document 2') are disclosed.
[0005] Patent Documents 1 and 2 described above adopt a structure for raising and lowering a water barrier plate, positioning the water barrier plate (water barrier door) on the lower side of the entrance to perform a water barrier function. However, most of them are examples in which a driving motor is installed at the top of the entrance, and a winch-type drum is driven by a driving motor using a traction wire or chain method to simply raise and lower the water barrier plate vertically, thereby securing the entrance when the water barrier plate is not needed.
[0006] However, the structure for raising and lowering the water barrier by towing it with a wire as described above has been pointed out as having the following problems.
[0007] First, the water barrier plate is provided with packing on both sides and the bottom to maintain airtightness against water pressure, and the seal is maintained through the packing portion. However, in the case of Patent Document 1, the water barrier plate is of the type that enters between the packings to be sealed, and in Patent Document 2, a watertight packing for the joint portion of the multi-stage water barrier plate is illustrated, so there is a problem that the water barrier plate descending along the guide rail has low airtightness.
[0008] Generally, the packing applied in Patent Documents 1 and 2 can withstand weak flood levels, but there is a problem where the airtightness is significantly reduced when the water pressure increases with the height of the flooding water.
[0009] In addition, since traction is performed by wires, lifting must occur when the water barrier is accurately leveled; however, there is a disadvantage that if the degree of wire winding on both sides is twisted, accurate lifting cannot be achieved while maintaining the level.
[0010] The present invention was developed to solve the aforementioned conventional problems. Its purpose is to provide a lifting-type water barrier that improves the water barrier designed to prevent rainwater from overflowing and entering the interior by adopting a self-lifting structure of the barrier plate instead of a separate traction method. This allows for simple installation at entrances where people or vehicles pass, ensuring the barrier is positioned above the entrance to secure access during normal times, while blocking the entrance in emergencies.
[0011] Another objective of the present invention is to enable the use of a water-blocking device to respond to fires that may occur due to abnormal defects during the charging of an electric vehicle battery.
[0012] The lifting water barrier of the present invention for achieving the above objective is,
[0013] The device is characterized by comprising: a post fixed vertically on both walls of an open entrance; a vertical guide member attached to each of the posts; a water barrier plate having guide rollers on both sides in a rectangular shape, packings for airtightness attached to both sides and the bottom of one side, and a lifting drive unit provided on both sides of one side to guide the vertical guide member and enable self-lifting movement; and a pressure plate attached to the lower front of the vertical guide member to maintain airtightness by pressing the packings on the water barrier plate side that have descended along the vertical guide member.
[0014] The lifting drive unit on the water barrier plate side according to the present invention is characterized by being composed of a driving motor, a reduction gear installed on the driving motor side, and a driving gear installed on the output shaft of the reduction gear and engaged with a vertical guide part to lift the water barrier plate.
[0015] The vertical guide member according to the present invention is characterized by being composed of a rail member having a guide slot formed longitudinally on one surface with a rack gear formed thereon and attached to a post, and a roller guide member attached to one side of the guide slot formed in the rail member to guide a guide roller on the water barrier side as the water barrier plate moves up and down.
[0016] The guide slot of the rail member and the lower side of the roller guide member according to the present invention are characterized by being formed in a rounded shape on the vertical side to guide the descending water barrier plate to advance in one direction.
[0017] The upper portion of the rail member according to the present invention is extended at a right angle, and the upper portion of the roller guide member is characterized by having a curved portion extended to guide the guide roller so that the guide roller maintains the water barrier plate, which is raised along the rail member extended at a right angle, in a horizontally rotated state.
[0018] The walls on both sides of the entrance according to the present invention are characterized by being installed such that a U-shaped perimeter wall is erected from the ground based on a post, and the barrier is formed in such a way that the vehicle is confined in a parked state by raising and lowering a barrier plate.
[0019] The lifting type water barrier according to the present invention allows the water barrier to be positioned and maintained at the upper side of the vertical guide section along the vertical guide section or positioned at the ground side, which is the lower side of the vertical guide section, through a lifting drive unit provided on both sides of one side of the water barrier plate, thereby enabling water barrier to be achieved. In particular, the descending water barrier plate is operated in such a way that it is pressed against a pressure plate through a guide hole of the rail member of the vertical guide section and a portion formed on the lower side of the roller guide member to seal the packing of the water barrier plate, or is raised in a separated state by reverse driving of the lifting drive unit to open the entrance / exit, so that there is no wear on the packing. This provides the advantage of being able to maintain the raised position of the water barrier plate along with an efficient water barrier function on the entrance / exit side where the water barrier device is applied, which can be done in a way that increases safety compared to the lifting method of the water barrier plate by the traction wire of the existing water barrier device.
[0020] In addition, the water barrier using a water barrier plate blocks the inflow of rainwater from the outside, and conversely, by providing a perimeter wall, it can be utilized to extinguish a fire in an electric vehicle parked in the event of a fire by trapping the parked vehicle within the wall and flooding the underside of the vehicle using firefighting water.

[0031] The present invention will be described in more detail below with reference to the attached drawings.
[0032] Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.
[0033] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
[0034] The lifting water barrier according to the present invention is described as follows with reference to the attached FIGS. 1 to 10.
[0035] The lifting water barrier according to the present invention is composed of a post (10), a vertical guide part (30), a water barrier plate (40), and a pressure plate (50).
[0036] The above post (10) is a square timber and is fixed vertically to both side walls of an entrance (11) that is open to a building, an underground passage, or an underground parking ramp.
[0037] Although not shown in the drawing, a separate crossbar is attached to the upper part of the vertically installed post (10) as described above to further support the post.
[0038] The above vertical guide section (30) is attached to each of the above posts (10).
[0039] When looking closely at the vertical guide section (30) above, as shown in the attached FIGS. 2 and 3, it is composed of a rail member (31-1) that is attached to a post (10) and has a guide slot (31) formed in the longitudinal direction with a rack gear (31a) formed on one side, and a roller guide member (32-1) that is attached to one side of the guide slot (31) formed in the rail member (31-1) and guides the guide roller (41) on the side of the water barrier plate (40) to be described later as the water barrier plate (40) rises and falls.
[0040] The above rail member (31-1) is manufactured by using a metal plate with thickness to form a guide slot (31) and a rack gear (31a) on its inner surface, and the above roller guide member (32-1) is manufactured in the form of a rail having a U-shaped cross-section for guiding the rolling of the guide roller (41).
[0041] The guide slot (31) of the rail member (31-1) and the lower side of the roller guide member (32-1) are formed in a rounded shape on the vertical side to guide the descending water barrier plate (40) to advance in one direction.
[0042] The above water barrier plate (40) is a rectangular shape having thickness, and guide rollers (41) are provided on both sides thereof to allow rolling. Packings (42, 43) for airtightness are attached to both sides and the bottom of one side, and a lifting drive unit (44) is provided on both sides of one side to be guided by the vertical guide unit (30) and perform a self-lifting movement.
[0043] The lifting drive unit (44) on the side of the above-mentioned water barrier plate (40) is composed of a drive motor (44a), a reduction gear (44b) installed on the side of the drive motor, and a drive gear (44c) installed on the output shaft of the reduction gear and engaged with the rack gear (31a) of the vertical guide unit (30) to lift the water barrier plate (40).
[0044] The above-mentioned pressure plate (50) is an L-shaped angle and is a component that is attached to the lower front surface of the vertical guide section (30) to maintain airtightness by closely adhering to the packing (42) on the water barrier plate (40) side that has descended along the vertical guide section (30).
[0045] Meanwhile, in the lifting water barrier of the present invention, the upper part of the rail member (31-1)
[0046] As illustrated in the attached FIGS. 7 and 8, the uppermost part of the rail member (31-1) is extended at a right angle, and the upper part of the roller guide member (32-1) is formed with a curved portion (33) that guides the guide roller (41) to maintain the water barrier plate (40), which is raised along the rail member (31-1) extended at a right angle, in a horizontally rotated state.
[0047] Meanwhile, the lifting water barrier according to the present invention can be configured such that the walls on both sides of the entrance (11) are U-shaped perimeter walls (W) built from the ground based on the post (10), thereby trapping the vehicle in a parked state by raising and lowering the water barrier plate (40).
[0048] The above-mentioned perimeter wall (W) is constructed by laying wall blocks, and forms a partition wall having an entrance (11) with one side open for the entry and exit of a vehicle (C), so that it can also be used as a parking space for parking a vehicle inside.
[0049] This serves two purposes: to prevent or protect against flooding of an electric vehicle parked in a parking line within the perimeter wall (W) for battery charging, or a conventional vehicle (C) parked in an external parking line. Additionally, by applying the lifting water barrier of the present invention, it can be used for water barrier purposes that are useful for protecting parked vehicles, separating them from the surroundings from fires that may occur during battery charging, and for fire suppression.
[0050] The operation of the lifting water barrier according to the present invention, configured as described above, is as follows regarding installation and operation.
[0051] First, a post is erected on the side walls or middle wall of a specific area where vehicles and people can pass from the ground, such as the entrance (11) of a building, the entrance (11) of an underpass provided in the form of a tunnel on a road, or the entrance (11) of an underground parking ramp, and a vertical guide part (30) is attached to the post.
[0052] In the guide hole (31) on the rail member (31-1) constituting the vertical guide section (30), a drive gear (44c), which is a component of the lifting drive section (44) provided on both sides of one side of the water barrier plate (40), is guided and engaged with the rack gear (31a). At the same time, the guide rollers (41) provided on both sides of the water barrier plate (40) are installed to be guided by the roller guide member (32-1) installed on the rail member (31-1) side.
[0053] In the above state, a driving gear (44c) is positioned in the guide hole (31) and a guide roller (41) is positioned in the roller guide member (32-1), respectively, so that lifting and lowering can be achieved.
[0054] The above water barrier plate (40) normally remains in a raised state on the uppermost part of the rail member (31-1) constituting the above vertical guide part (30), and when a flood emergency is declared due to flooding caused by rain, it is lowered to block the lower part of the entrance (11), thereby blocking the entrance to a low-lying underpass, building entrance, or underground parking ramp at the height of the water barrier plate (40) to prevent water from being pushed in by rainwater.
[0055] The lowering of the above-mentioned water plate (40) is achieved by driving the drive motor (44a) and reduction gear (44b) constituting the lifting drive unit (44), so that the drive gear (44c) on the output shaft is engaged with the rack gear (31a) formed on the guide hole (31) of the rail member (31-1).
[0056] As described above, the vertically descending water barrier plate (40) is finally lowered by changing from a vertical state to a forward state by having a rounded shape on the lower side of the guide hole (31) and roller guide member (32-1) before being positioned on the ground.
[0057] This ensures that the packing (42) provided on both sides of one side of the water barrier plate (40) is in close contact with the pressure plate (50) installed on the lower side of the guide part (30), and the packing (43) on the lower side of the water barrier plate (40) is in close contact with the ground side, thereby creating an airtight state.
[0058] As described above, the fact that the vertically descending water barrier plate (40) descends while performing a final forward movement toward the pressurizing plate (50) ensures that, compared to the sealing method of existing water barrier facilities where the sealing plate is lifted and contacted with the packing, the seal is achieved by being pressed tightly against the pressurizing plate (50) while eliminating frictional interference with the packing. This not only protects the packing responsible for sealing but also satisfies the final pressurizing condition of the sealing plate due to the driving of the lifting drive unit, thereby maintaining a safe sealing state.
[0059] In addition, during the process of raising and lowering the water barrier plate (40) in reverse, the water barrier plate attached to the pressure plate (50) moves vertically away from the round point of the guide hole (31) and the roller guide member (32-1), i.e., is ejected. Since the water barrier plate rises while separating from the pressure plate due to reverse driving of the lifting drive unit (44), unnecessary friction is not applied to the packing (42), thereby providing the advantage of significantly extending the service life of the packing.
[0060] As described above, the water barrier created by the pressure sealing condition of the stable packing acts as a stable barrier even against the water pressure of incoming water, thereby preventing water from flowing in and causing flooding, especially on the lower side.
[0061] Meanwhile, the vertical guide member (30) according to the present invention, as shown in the embodiment illustrated in the attached FIGS. 7 and 8, applies the curved portion (33) of the roller guide member (32-1) which is extended perpendicularly from the upper part of the rail member (41-1), so that the water barrier plate (40) raised to the uppermost part of the guide hole (31) of the rail member (31-1) as described above moves along the curved portion (43) by the driving of the lifting drive member (44), thereby allowing the water barrier plate (40) including the lifting drive member (44) to rotate with respect to the driving gear (44c) and be maintained horizontally.
[0062] The above point provides the advantage of ensuring a height limit for vehicles passing through the entrance (11) by maximizing the height of the entrance.
[0063] As described above, the horizontally rotated water barrier plate (40) is vertically lowered by the reverse drive of the lifting drive unit (44), and the operation of advancing and advancing toward the pressure plate (50) while positioned at the lower side is implemented in the same manner.
[0064] Meanwhile, as illustrated in the attached FIGS. 9 and 10, the water barrier according to the present invention can be installed and operated in an individual parking space or in a parking space for one or more vehicles in a parking line where a vehicle is parked.
[0065] This is achieved by establishing an entrance (11) through which a vehicle can enter and exit by setting up a post (10) from the ground, and then constructing a U-shaped perimeter wall (W) on both sides of the entrance (11) based on the post (10), thereby allowing the vehicle to be parked inside the perimeter wall.
[0066] A vertical guide section (30) including a pressure plate (50) is attached to the above-mentioned post (10), and a water barrier plate (40) including a lifting drive section (44) is installed as described above, thereby making it usable for water barrier purposes.
[0067] The application of the above-mentioned water barrier can prevent water from entering from the ground and the pressurized area by lowering the water barrier plate and pressing the packing on the water barrier plate side from the outside, thereby preventing the vehicle from being flooded.
[0068] Alternatively, in the case of a parked electric vehicle requiring battery charging, it can also be utilized to suppress a fire caused by an abnormal defect in the battery during charging after parking by rapidly supplying firefighting water to the inside of the perimeter wall while the water barrier is lowered and blocked as described above, thereby flooding the lower side of the vehicle where the electric vehicle battery is located.
[0069] The above method allows for the suppression of a fire under conditions where the electric vehicle is submerged, by providing a fire water supply pipe (P) and a fire detection sensor (S) provided around the perimeter wall (W), along with a separate drain (W1) at the bottom of the perimeter wall.
[0070] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.
[0071] Accordingly, the scope of the present invention should not be limited to the described embodiments, and all things equivalent to or having equivalent variations to the claims set forth below, as well as the claims set forth below, shall be considered to fall within the scope of the concept of the present invention.
