[0003] If rainwater flows into the interior of a building or underground facility, most of the items inside may be submerged and damaged, resulting in serious economic and psychological damage.

[0004] Accordingly, various types of water barrier devices have been proposed to prevent rainwater from entering indoors by installing water barriers at entrances when heavy rainfall occurs, and research and development are continuously underway.

[0005] Various types of doorway water barrier devices are proposed and used, including manual installation methods in which a water barrier is installed via a pair of fixed posts on both sides of the doorway when it is necessary to block the inflow of rainwater, and lifting operation methods in which a water barrier installed embedded in the ground to be movable is raised via a lifting means such as a lifting cylinder.

[0006] The present invention relates to a lifting water barrier device, among various types of entrance water barrier devices, in particular in which a water barrier is embedded in the floor surface of an entrance so as to be vertically movable, and the water barrier is operated to be vertically movable through a lifting cylinder.

[0007] The lifting water barrier device to which the present invention relates includes a lifting operating means such as a lifting cylinder, so although the construction cost is relatively high compared to a manual installation method in which a worker must directly install or remove a heavy water barrier, it has the advantage of being able to install the water barrier more quickly when heavy rain occurs and easily remove the water barrier when the dangerous situation ends.

[0033] In the following, "upward," "downward," "forward," "rearward," and other directional terms are defined based on the state depicted in the drawings.

[0034] FIG. 1 is a front view of a lifting barrier device according to the present invention, FIG. 2 is a plan view of a lifting barrier device according to the present invention, FIG. 3 is an exploded perspective view of a key part of a lifting barrier device according to the present invention, and FIG. 4a and FIG. 4b are longitudinal cross-sectional views of a key part showing the operating state of a barrier device according to the present invention.

[0035] The lifting barrier device (100) according to the present invention includes a landfill foundation (110), a lifting guide support (120), a lifting guide wall (130), a barrier wall (140), and a lifting cylinder (150).

[0036] The buried foundation (110) is a part in which the elevator guide wall (130) and the lowered water barrier wall (140) are embedded, and is installed buried in the ground of the entrance.

[0037] The landfill foundation (110) has a storage space (111) with an open top, and a sealed space (112) with a wider front-to-back width than the storage space (111) is provided on the upper part of the storage space (111).

[0038] The lifting guide posts (120) are parts that guide the lifting of the lifting cylinder (150) and are installed on both sides inside the storage space (111) of the buried foundation (110).

[0039] The elevator guide support (120) is in the shape of a "C" with an open inner side, and its lower part is installed inside the storage space (111) of the buried foundation (110), while its upper part protrudes above ground.

[0040] The elevator guide wall (130) is a part that guides the elevator of the water barrier wall (140) and is installed inside the storage space (111) of the buried foundation (110).

[0041] The elevator guide wall (130) is installed inside the storage space (111) and includes a front wall (131) and a rear wall (132) spaced apart by a width corresponding to the front-rear width of the water barrier wall (140); an "L"-shaped rear support member (133) installed in the rear interior of the sealed space (112), with the front end of the horizontal portion fixed to the upper rear portion of the rear wall (132); and a front support member (134) installed in the front interior of the sealed space (112) with a shape symmetrical to the rear support member (133), with the rear end of the horizontal portion fixed to the upper front portion of the front wall (131).

[0042] A drainage channel (135) is provided between the vertical section of the rear support member (133) of the elevator guide wall (130) and the rear wall (132), and between the vertical section of the front support member (134) and the front wall (131), so that rainwater can flow down in the left and right directions.

[0043] The water barrier (140) is a part that prevents rainwater from entering the interior through the entrance, and is installed so as to be movable inside the elevator guide wall (130).

[0044] The water barrier (140) has a front-to-back thickness of a certain width and has a rectangular shape with a horizontal length longer than the vertical height and a hollow interior.

[0045] The front and rear ends of the upper plate (143) of the water barrier (140) are bent vertically and protrude toward the front of the front plate (141) and the rear of the rear plate (142). A first sealing member (144) is installed at the lower front and rear of the upper plate (143) to be in close contact with the upper end of the front wall (131) and the upper end of the rear wall (132) of the lifting guide wall (130) in the lower storage state of the water barrier (140). A second sealing member (145) is installed at the lower front of the front plate (141) and the lower rear of the rear plate (142) to seal the space between the water barrier (140) and the lifting guide wall (130).

[0046] The water barrier (140) is connected to the cylinder body (151) of the lifting cylinder (150) through a connecting bracket (146) that is detachably installed on both sides of its upper side.

[0047] The lifting cylinder (150) is a part that lifts the water barrier (140) and is installed in the lower inner part of the lifting guide post (120).

[0048] The cylinder body (151) of the lifting cylinder (150) is fixedly installed on the water barrier wall (140) through a connecting bracket (146) that is detachably installed on the top of the water barrier wall (140), and the operating rod (152) of the lifting cylinder (150) is fixedly installed on the lifting guide support (120) through a mounting frame (160).

[0049] Accordingly, when the lifting cylinder (150) is extended, the operating rod (152) is fixed to the lifting guide support (120), and the cylinder body (151) and the water barrier (140) mounted thereon are raised.

[0050] A mounting frame (160) that allows the operating rod (152) of the lifting cylinder (150) to be fixed to the lifting guide support (120) is in the shape of a “U” with both sides and the top open, the front and rear ends are fastened and fixed to the lifting guide support (120), and the operating rod (152) is tightly fixed to the inner lower surface.

[0051] The connection portion between the mounting frame (160) and the lifting guide support (120) is provided at the portion where the lifting guide support (120) protrudes above the ground.

[0052] The sealing plate (190) is a part that seals the sealed space (112) of the landfill foundation (110) and is installed on the upper inside of the sealed space (112).

[0053] A landing block (191) is installed at the lower front and lower rear of the sealing plate (190) and is in close contact with the upper horizontal portion of the front support member (134) and the upper horizontal portion of the rear support member (133).

[0054] The lifting water barrier device (100) according to the present invention, like the lifting water barrier device according to the prior art, can block rainwater entering the interior through the entrance by protruding the water barrier (140) stored in the storage space (111) of the buried foundation (110) to the ground when the lifting cylinder (150) is operated to lift in a situation where heavy rain and other conditions prevent proper drainage around the entrance, thereby preventing rainwater from entering the interior.

[0055] In addition, when the risk of heavy rain or similar events ends and drainage in front of the entrance proceeds smoothly so that there is no longer a need to worry about rainwater inflow, if the lifting cylinder (150) is lowered, the protruding water barrier (140) is stored back into the storage space (111) of the landfill foundation (110), thereby normalizing the entrance.

[0056] Meanwhile, in the elevator water barrier device (100) according to the present invention, when the water barrier (140) is in a lowered state, the sealed space (112) is sealed through the sealing plate (190), and the first sealing member (144) installed at the lower front and rear of the upper plate (143) is firmly attached to the upper end of the front wall (131) and the upper end of the rear wall (132) of the elevator guide wall (130), so that foreign matter is not introduced into the interior of the storage space (111).

[0057] In addition, even if rainwater or sewage flows in through the gap between the sealing plate (190) and the rear support member (133) and the gap between the sealing plate (190) and the front support member (134) while the water barrier (140) is in a lowered state, it can be discharged to the outside through the drainage channel (135) provided between the vertical part of the rear support member (133) of the lifting guide wall (130) and the rear wall (132), and between the vertical part of the front support member (134) and the front wall (131).

[0058] In the lifting water barrier device (100) according to the present invention, when a vertical load is applied to the sealing plate (190) by the passage of people or vehicles while the water barrier (140) is in a lowered state, the vertical load is transmitted to the buried foundation (110) through the landing block (191) installed at the lower front and lower rear of the sealing plate (190), the front support member (134), and the rear support member (133), so that the water barrier (140) does not descend or move due to the vertical load applied to the upper part of the sealing plate (190) and can maintain a stable storage state.

[0059] The lifting water barrier device (100) according to the present invention can be easily constructed through a relatively simple construction process in which a lifting guide support (120) and a lifting guide wall (130) are installed inside the storage space (111) of the buried foundation (110), a lifting cylinder (150) is installed on the lifting guide support (120) through a mounting frame (160), a water barrier (140) is inserted and installed on the lifting guide wall (130), and the water barrier (140) and the cylinder body (151) of the lifting cylinder (150) are connected through a connecting bracket (146).

[0060] The lifting water barrier device (100) according to the present invention allows the water barrier (140) to be easily separated from the lifting cylinder (150) even when inspecting or repairing some parts after construction, and the mounting frame (160) and the lifting cylinder (150) can be easily separated from the lifting guide support (120), thereby making it easier to inspect and repair parts.

[0061] Although the invention made by the inventors has been specifically described according to the above embodiments, the present invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof. Explanation of the symbols
