Description

Multi-stage lifting type blocking module and blocking structure using the same

[0001] The present invention relates to a multi-stage lifting blocking module and a blocking structure using the same, and more specifically, to a multi-stage lifting blocking module and a blocking structure using the same in which the lifting module automatically rises and expands in multiple stages by means of buoyancy generated when fluid flows into the interior of the blocking module, thereby blocking the movement of fluid.

[0002] With the expansion of urbanization and the use of underground spaces, there has been an increase in cases of backflow and flooding damage caused by the rapid influx of fluids into manholes, storm drains, pits, retention tanks, and basement entrances beneath roads due to torrential rain or sudden water inflows. Accordingly, various blocking devices, check valves, flap gates, sluice gates, and pop-up waterproofing panels have been proposed to block rainwater or sewage from flowing backward.

[0003] Conventional shut-off devices generally have a fixed shut-off height or a structure in which a single panel moves up and down, and often lack a structure that allows the shut-off height to be adjusted in stages in response to the water level. Furthermore, many utilize separate drive sources such as electric motors or cylinders for operation, making them vulnerable to power outages, breakdowns, and poor maintenance. Additionally, they face limitations in that it is difficult to simultaneously maintain an open state during normal operation and enable automatic operation in the event of flooding.

[0004] Meanwhile, Japanese Patent Publication No. 2011-025955 is disclosed as one of the technologies regarding a conventional multi-stage expandable rainwater storage device.

[0005] The present invention was developed to improve upon the aforementioned problems, and the objective of the present invention is to provide a multi-stage lifting blocking module and a blocking structure utilizing the same, wherein the lifting module automatically rises and expands in multiple stages by means of buoyancy generated when fluid flows into the interior of the blocking module to block the movement of fluid.

[0006] A multi-stage lifting blocking module according to the present invention comprises: a fixed block (100) positioned at the lowest side, wherein an inlet (110) and an outlet (120) are formed on one side and the interior is hollow; at least one rising block (200) positioned in a state of being inserted into the fixed block (100) and formed to rise in an upward direction by buoyancy when the interior of the fixed block (100) is filled with fluid; and a shaft portion (300) installed to guide the lifting of the rising block (200); wherein the rising block (200) automatically rises by the buoyancy generated as fluid flows into the interior of the fixed block (100) to perform a blocking function.

[0007] At this time, the above-mentioned rising block (200) is configured to form multiple layers, so as to form a multi-stage rising structure that rises step by step from the bottom to the top by buoyancy.

[0008] In addition, the uppermost rising block (200) among the plurality of rising blocks (200) may be formed with a sealed internal structure so that fluid does not flow into the interior of the rising block (200).

[0009] Meanwhile, the shaft portion (300) comprises a base shaft (310) fixed to a plurality of fixed blocks (100); and a lifting shaft (320) coupled to each of a plurality of lifting blocks (200) to form a fitting connection with the base shaft (310) and adjacent lifting shafts (320); wherein the lifting shaft (320) can be extended in multiple stages in conjunction with the lifting of the corresponding lifting block (200).

[0010] Meanwhile, the above-mentioned rising block (200) is formed around the connection portion with the shaft portion (300) and further provided with a fluid flow hole (210) through which fluid passes by connecting the internal space of the lower fixed block (100) or the adjacent lower rising block (200) with the internal space of the rising block (200).

[0011] Meanwhile, adjacent rising blocks (200) can be connected through a connecting projection (410) and a connecting groove (420) to prevent rotation or twisting during the lifting and lowering of the rising blocks (200).

[0012] A multi-stage lifting blocking structure (1) utilizing a multi-stage lifting blocking module (10) according to the present invention is characterized in that a plurality of the multi-stage lifting blocking modules (10) can be connected and arranged in one direction to form a wall structure, or arranged in a closed curve shape to form a partition area, and can be implemented as a buried type, a mounted type, or a movable type.

[0013] According to the present invention, since the rising block is structured to automatically ascend and descend sequentially using the buoyancy of the fluid flowing into the fixed block, it has the advantage of enabling powerless automatic shut-off without a separate power source or driving device. In addition, buoyancy is transmitted stepwise from the bottom to the top through a fluid flow hole connecting a plurality of rising blocks and each floor, thereby expanding the shut-off height in multiple stages according to the water level and maintaining uniform lifting responsiveness at each stage.

[0014] In addition, the shaft structure, which expands in multiple stages through a snap-fit ​​connection between a base shaft fixed upright to a fixed block and a lifting shaft coupled to each rising block, and the square cross-section coupling protrusions and grooves applied between the fixed block and the rising block, suppress twisting or rotation of the block during the lifting process and stably maintain the alignment with the central axis of the blocking module. By forming the uppermost rising block as a sealed structure and applying an upper sealing block and cushioning pad as needed, the upper end at the deployment end is sealed with a continuous wall, thereby reducing leakage and impact, and improving the blocking performance and durability of the uppermost section.

[0015] Furthermore, the blocking module according to the present invention can be buried underground and applied linearly to rainwater inlets or the top of manholes, and can also be extended to form a blocking structure that creates a closed-curve-shaped partition area by arranging multiple identical modules. Accordingly, it can be configured not only as a buried structure but also as a mounted or movable structure attached to a frame or support, thereby offering the advantage of being able to accommodate various installation environments and uses.

[0026]

[0027] The present invention relates to a multi-stage lifting blocking module (10) and a blocking structure (1) using the same, and more specifically, to a multi-stage lifting blocking module and a blocking structure using the same in which the lifting module (200) automatically rises and expands in multiple stages by means of buoyancy generated when fluid flows into the interior of the blocking module (10) to block the movement of fluid.

[0028]

[0029] As illustrated in FIG. 1a and FIG. 1b, the multi-stage lifting blocking module (10) according to the present invention comprises a fixed block (100) positioned at the bottom side, which is configured with an inlet (110) and an outlet (120) formed on one side and has a hollow interior, at least one rising block (200) positioned in a state of being inserted into the fixed block (100) and formed to rise in an upward direction by buoyancy when the interior of the fixed block (100) is filled with fluid, and a shaft portion (300) installed to guide the lifting of the rising block (200), and is characterized by a structure in which the rising block (200) automatically rises by the buoyancy generated as fluid flows into the fixed block (100) to perform a blocking function.

[0030]

[0031] As shown in FIG. 3, the multi-stage lifting blocking module (10) may be configured with first, second, third, fourth, and fifth rising blocks (200) sequentially upward from the block located at the lowest side when expanded in multiple stages. In the following description, a five-stage structure consisting of five rising blocks (200) is described as an example, but the number of rising blocks (200) may be arbitrarily changed according to the usage environment or the required blocking height, and the present invention is not limited thereto.

[0032] To aid in understanding the invention, the direction in which the fixed block (100) and the rising block (200) are arranged in a left-right direction is defined as the X-axis direction, the horizontal direction perpendicular thereto is defined as the Y-axis direction, and the direction in which the rising block (200) moves up and down is defined as the Z-axis direction.

[0033]

[0034] As illustrated in FIG. 1a and FIG. 3, the fixed block (100) is a member that forms the outer shape of the multi-stage lifting blocking module (10) and constitutes the lowest layer where fluid is stored, having an inlet (110) and an outlet (120) that communicate with the outside formed on one side, and a storage space where fluid is stored is provided inside.

[0035] The inlet (110) is formed at a position higher than the maximum water level of the inner storage space of the fixed block (100), and fluid introduced from the outside through the inlet (110) flows into the fixed block (100) to form a water level, and the buoyancy acting on the rising block (200) is determined according to this change in water level. The outlet (120) is formed at the bottom of the fixed block (100) and is used as a passage to discharge the fluid stored inside the fixed block (100) to the outside, and when the fluid is discharged, the rising block (200) performs the operation of returning to its original position by its own weight.

[0036] A plurality of fixed blocks (100) can be arranged side by side in the X-axis direction to form a blocking module (10) having a wide width, and a pair of fixed blocks (100) adjacent to each other on the left and right sides have a structure in which they are fastened by a coupling projection (410) and a coupling groove (420). It is preferable that the cross-sections of the coupling projection (410) and the coupling groove (420) be formed in a square shape, thereby allowing the fixed blocks (100) to be firmly fastened while maintaining an alignment state in the left and right directions.

[0037]

[0038] Side blocks (130) that assist in the lifting of the lifting block (200) may be further provided at both ends of the fixed block (100). A guide groove (131) that guides the lifting of the lifting block (200) is formed on the inner surface of the side block (130), and the two ends of the fixed block (100) into which the lifting block (200) is inserted are respectively placed in the guide groove (131). The guide groove (131) may be configured in the form of a multi-stage groove to limit the maximum lifting height of each lifting block (200), and multi-stage grooves are formed at corresponding positions on a pair of side blocks (130) facing each other. The multi-stage grooves are formed to have different front-to-back widths and form a stepped structure in which the width gradually decreases as it goes upward, thereby stably guiding the lifting of the lifting block (200) and defining the maximum height of each lifting stage.

[0039] Between the tops of a pair of side blocks, an upper sealing block (160) is further provided, which engages with the upper end of the top rising block (200e) in a fully extended state. The upper sealing block (160) includes a groove into which the upper end of the top rising block (200e) can be inserted and closely fitted, and as the end of the top rising block (200e) is inserted into this groove and closely fitted, the rising block can be stably erected. Additionally, the upper sealing block (160) forms a structure that covers the top of the top rising block (200e), and by acting as a wall that closes the top in a fully extended state, it enhances the blocking effect. At this time, a cushioning pad (not shown) made of an elastic material is further provided between the upper sealing block (160) and the top rising block (200e) to mitigate the impact that may occur when the two components come into contact.

[0040] A fixed block cover (140) is provided on the outer side of the fixed block (100) to protect the fixed block (100) from the external environment. A barrier cover (150) is provided on the top of the fixed block (100) and is hinge-connected so as to be openable and closable by a rising block (200). Normally, the fixed block (100) is covered and protected by the barrier cover (150), and can be automatically opened by the rising block (200) when fluid flows in.

[0041]

[0042] According to FIGS. 3 and 4, the rising block (200) is arranged in a manner that is inserted into the fixed block (100), and the upper rising block (200) is inserted into the lower rising block (200) to form a structure that is sequentially stacked in the Z-axis direction. In the folded state, a plurality of rising blocks (200) are stacked in an overlapping state, and at this time, it is preferable to configure the total height so that it corresponds to the top of the fixed block (100).

[0043] As illustrated in FIGS. 4 and 6, when fluid flows into the fixed block (100), the first rising block (200a) first receives buoyancy and rises in the Z-axis direction, and when the first rising block (200a) reaches a certain height and fills with fluid, the second rising block (200b) placed on top of it receives additional buoyancy and rises. As this process is repeated, the third, fourth, and fifth rising blocks (200c, 200d, 200e) rise sequentially, and the entire rising block (200) unfolds in stages, forming a multi-stage lifting structure in which the blocking height automatically increases in proportion to the level of the incoming fluid.

[0044] As illustrated in FIG. 7, a plurality of rising blocks (200) can be arranged side by side in the X-axis direction to form a blocking module (10) having a wide width, and a pair of rising blocks (200) adjacent to each other on the left and right can have a structure in which they are fastened by a coupling projection (410) and a coupling groove (420). This coupling structure can have the same shape as the coupling structure of the fixed block (100), and this will be explained in more detail later.

[0045]

[0046] As shown in FIGS. 3 to 7, the uppermost rising block (200) can be formed with a sealed structure that prevents fluid from flowing into it. Since the uppermost rising block (200) configured as a sealed structure prevents fluid from flowing into it, it can suppress unnecessary weight increase at the top, thereby improving the lifting responsiveness of the entire blocking module (10). In addition, even during repeated operation, no residual water remains inside, enabling stable return operation, and by maintaining watertightness at the top, leakage can be prevented near the final blocking height.

[0047] Meanwhile, the uppermost rising block (200) is designed to descend stably by its own weight and return to its original position when the fluid is discharged. For example, operational stability can be enhanced by forming it as a single mass so that there is no empty space inside. Additionally, adjacent rising blocks (200) in the X-axis direction can be connected by a locking projection (510) and a locking groove (520), and these connecting parts are connected in the Z-axis direction so that the locking is smooth during lifting.

[0048]

[0049] As illustrated in FIGS. 3 to 6, the shaft portion (300) is arranged along the center of the blocking module (10) in the Z-axis direction and serves to guide the lifting of the fixed block (100) and the lifting block (200). The shaft portion (300) includes a base shaft (310) that is fixed upright on the fixed block (100), and a plurality of lifting shafts (320) that are coupled to each of the plurality of lifting blocks (200) so as to be coaxial with the base shaft (310).

[0050] Multiple lifting shafts (320) are lifted integrally with the corresponding lifting blocks (200), and adjacent lifting shafts (320) and base shafts (310) are configured to be fitted together in the vertical direction to enable relative movement. Accordingly, when each lifting block (200) rises sequentially due to buoyancy, the lifting shafts (320) connected thereto also rise together, and by moving relative to each other while fitted together, the base shafts (310) and lifting shafts (320) are extended together in the Z-axis direction in multiple stages. In this way, the shaft section (300) forms the axis of the module during the lifting process and simultaneously guides the lifting path of each block in a straight line.

[0051] As illustrated in FIG. 8, each rising block (200) may have a fluid flow hole (210) formed around the connection portion with the shaft portion (300) through which fluid passes. The fluid flow hole (210) is a passage that sequentially connects adjacent spaces, such as the interior space of the fixed block (100), the interior of the first rising block (200a), the interior of the first rising block (200a) and the second rising block (200b), and the interior of the second rising block (200b) and the third rising block (200c), and is configured to allow the incoming fluid to move from the bottom to the top. Multiple fluid flow holes (210) may be formed around the center of the rising block (200), that is, around the lifting shaft (320), and buoyancy is transmitted as the fluid flows into each block in stages. Additionally, to prevent fluid flow concentration, they are distributed along the perimeter, and the inner surface is formed to minimize fluid resistance, thereby mitigating pressure fluctuations and maintaining a uniform lifting speed.

[0052]

[0053] As illustrated in FIG. 7, a coupling structure including a coupling projection (410) and a coupling groove (420) is applied between the fixed blocks (100) and between the rising blocks (200). Between the fixed blocks (100) arranged side by side in the X-axis direction, one coupling projection (410) and the other coupling groove (420) are fastened, and a coupling of the same shape is applied between the rising blocks (200). The coupling projection (410) and the coupling groove (420) are formed with a square cross-section to suppress rotation or twisting when fastened and to maintain alignment.

[0054] Additionally, the coupling surface may be provided with a cushioning or watertight function as needed. A cushioning part (not shown) made of an elastic material may be installed on the coupling protrusion (410) or coupling groove (420), or a watertight packing (not shown) made of a moisture-expanding material may be attached to seal the gap by expanding upon contact with fluid.

[0055]

[0056] Meanwhile, a step projection (430) for limiting the lifting height is provided around the upper perimeter of the fixed block (100) and the rising block (200) to limit the lifting of the rising block (200). A step packing (not shown) for preventing collision and blocking fluid leakage may be further provided at the lower part of the step projection (430), and this may be composed of an elastic or moisture-expanding material.

[0057] In the blocking module (10) according to the present invention configured as described above, when fluid is introduced from the outside, it flows into the fixed block (100) through the inlet (110), and as the water level in the storage space rises, the first rising block (200a) rises first by receiving buoyancy. When the first rising block (200a) rises, the fluid moves upward through the fluid flow hole (210), and each rising block rises sequentially, so that the entire structure unfolds in multiple stages. When the fluid is discharged through the outlet (120) and the water level drops, as the buoyancy decreases, the fifth rising block (200e) to the first rising block (200a) descend by their own weight in reverse order and return to a folded state.

[0058]

[0059] As illustrated in FIGS. 1a and 1b, the blocking module (10) according to the present invention can be extended in one direction to form a blocking wall.

[0060] Meanwhile, as illustrated in FIGS. 2a and 2b, the blocking module (10) according to the present invention may be configured in the form of a closed curve. Specifically, the fixed block (100) and the rising block (200) each include a corner block (100a, 200a) and an extension block (100b, 200b), and are arranged so that a plurality of blocking modules (10) are connected in a closed curve. A closed curve blocking module configured in this way can form a single closed partition area instead of forming a wall in a single direction.

[0061] That is, when a plurality of blocking modules (10) are continuously connected in a closed curve, the rising block (200) automatically rises and falls according to buoyancy when fluid flows in, forming a partitioned closed zone, and the flow of fluid flowing in through that area can be completely blocked. This closed curve structure can be applied to various facilities, not only for waterproofing and fire prevention purposes, but also, as needed, by utilizing the internal area as a storage tank or isolation zone.

[0062]

[0063] As illustrated in FIGS. 9a to 9c, the multi-stage lifting blocking module (10) arranged and installed as described above can be used as a buried, mounted, or movable blocking structure (1).

[0064] The buried blocking structure (1) can be installed by being buried inside a concrete structure or a civil engineering structure as shown in FIG. 9a or 9b, and constructed so that the upper part is formed at the same height as the ground. Normally, it maintains a state integrated with the ground, and only when fluid flows in does the rising block (200) protrude to perform the blocking function. That is, the buried structure can be used as a permanent blocking facility integrated with the surrounding civil engineering structure.

[0065] As shown in FIG. 9c, a stationary or movable barrier structure (1) is installed on the ground by being fixed to a base frame (20) made of metal or synthetic resin or a box-shaped support (not shown). When necessary, it can be moved and installed using a vehicle or equipment, or disassembled and transported to another location for reuse. That is, the stationary structure is manufactured based on a frame, making it easy to replace modules and move, and it can be applied as a temporary or movable barrier facility.

[0066] The blocking structure (1) configured as described above can be extended to various application facilities depending on the installation type.

[0067] For example, in the embodiment of FIG. 9a, the blocking structure (1) is installed in the form of a wall at the entrance of an underground passage or underground parking lot, and can be used to block backflow or flooding of rainwater or other fluids.

[0068] In the embodiment of FIG. 9b, the blocking structure (1) is installed in a closed curve shape along the parking lines of an electric vehicle parking lot and can be utilized for special purposes such as fire extinguishing facilities. That is, by arranging the blocking modules (10) in a closed curve shape and supplying fire extinguishing water or water to the internal area, when a fire occurs, the rising block (200) rises to form a closed area and can extinguish the fire by submerging the electric vehicle in water.

[0069] In the embodiment of FIG. 9c, the blocking module (10) may be installed on landfill or above ground by arranging it in a desired closed curve shape and supplying liquid to the formed closed area, so that it may be used as a reservoir, water tank, swimming pool, or other liquid storage or circulation facility.

[0070] Alternatively, the blocking structure (1) can be configured to form various wall structures by arranging and installing the blocking modules (10) in various linear forms.

[0071]

[0072] As described above, the multi-stage lifting blocking module (10) and the blocking structure (1) using the same according to the present invention operate automatically by the buoyancy of the fluid, so no separate power source or driving device is required. Furthermore, the multi-stage structure allows for securing a blocking height corresponding to the level of the incoming fluid. Additionally, the lifting stability is improved through the square cross-section coupling structure and the multi-stage expansion shaft structure, and watertightness is maintained even during long-term use by applying a watertight packing to the coupling part as needed.

[0073]

[0074] Meanwhile, the present specification and drawings disclose preferred embodiments of the present invention. Although specific terms have been used, they are used merely in a general sense to facilitate the explanation of the technical content of the present invention and to aid in understanding the invention, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art that, in addition to the embodiments disclosed herein, other variations based on the technical concept of the present invention are possible.

[0075] The multi-stage lifting blocking module according to the present invention can be applied in various fields, such as vehicle entry blocking devices, pedestrian safety blocking structures, or opening blocking devices for public facilities, industrial facilities, etc., and is therefore industrially available.
