Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to an inflatable expansion module, a smart flood control structure, and a smart enclosure structure. Background Technology

[0002] Existing flood control technologies for entrances and exits (including subway entrances and exits, tunnel entrances and exits, underground parking garage entrances and exits, underground shopping mall entrances and exits, etc.) and embankments typically include traditional physical barriers (such as barriers and sandbags), fixed flood control facilities (such as riverbank flood walls, embankments, and floodgates), and inflatable expansion devices (such as inflatable rubber dams and elastic tunnel plugs).

[0003] The core of flood control technology is to increase height to achieve barrier effect. However, traditional physical barrier devices require manual installation and have a slow response time. The height of fixed flood control facilities (such as dikes) cannot be adjusted, lacking flexibility in use. Inflatable expansion devices also require manual placement and are prone to wear and tear over long-term use. Therefore, some existing flood control technologies have shortcomings. This application is based on an inflatable expansion module that can respond quickly and is not easily worn, and provides solutions for various aspects such as flood control at entrances and riverbanks and fencing through different installation structures. Summary of the Invention

[0004] The purpose of this invention is to provide an inflatable expansion module that has the functions of rapid response and resistance to wear.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an inflatable expansion module, including a bracket, an air pump mounted on the bracket, a solar power supply device mounted on the bracket and supplying power to the air pump, a double-layer airbag, and an inflation tube connecting the air pump and the double-layer airbag; the double-layer airbag includes an outer airbag and an inner airbag disposed inside the outer airbag, the inner airbag is provided with an inflation connector that extends out of the outer airbag and connects to the inflation tube, the inner airbag inflates and expands, thereby driving the outer airbag to inflate and expand, the outer airbag includes a woven outer layer and a rubber inner layer composited within the woven outer layer.

[0006] By adopting the above technical solution, the composite structure of the outer woven fabric layer and the inner rubber layer of the outer airbag, combined with the active expansion mechanism of the inner airbag, can disperse stress concentration and improve the overall compressive strength. When the inner airbag is inflated, it drives the outer airbag to expand synchronously through the inflation joint, forming a graded pressure-bearing mode, avoiding the single-layer structure from cracking due to local overload and reducing the risk of failure. Moreover, the combination of solar power supply device and air pump achieves energy self-sufficiency. Finally, it has the functions of rapid response and wear resistance during the inflation process of the double-layer airbag.

[0007] A further feature of this invention is that the solar power supply device includes a solar panel mounted on a support, a controller mounted on the support, and a storage battery mounted on the support. The controller is connected to the solar panel, the storage battery, and the air pump via signals. The solar panel supplies power to the storage battery, and the storage battery supplies power to the air pump.

[0008] By adopting the above technical solution, the solar panel converts solar energy into electrical energy and stores the electrical energy through the battery, which enables the air pump to maintain the inflation state for a long time, ensuring that the double-layer airbag can continue to maintain the inflation state after inflation.

[0009] A further feature of this invention is that an identification strip for marking is provided on the periphery of the external airbag.

[0010] By adopting the above technical solution, an identification strip is provided around the external airbag. The identification strip can be set with different markings according to different usage environments for reminder purposes.

[0011] A further feature of this invention is that: multiple inner airbags are provided, the multiple inner airbags are stacked, the inflation connector is connected to the lowest inner airbag, and a connecting connector is provided between any two inner airbags.

[0012] By adopting the above technical solution, multiple inner airbags are set up in a stacked manner. When combined with the external structure to limit the maximum expansion height of the outer airbags, the maximum height of the double-layer airbags can be adjusted after the expansion of several inner airbags within the height range.

[0013] The purpose of this invention is to provide a smart flood control structure that has the functions of rapid response, wear resistance, and efficient flood control and water blocking.

[0014] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a smart flood control structure, including a ground surface with a first mounting groove at the entrance / exit, an inflatable expansion module, and a grid cover; the double-layer airbag is disposed in the first mounting groove, the upper half of the double-layer airbag protrudes from the first mounting groove after inflation and is rectangular in shape, the double-layer airbag has first pressing edges on both sides along its length, the lowermost inner airbag is 30-50 cm higher than the first mounting groove after inflation, and the two sides of the double-layer airbag after inflation abut against the two side walls of the entrance / exit; the two sides of the first mounting groove are respectively provided with first metal pressure strips pressed against the first pressing edges and pre-embedded and fixed in the ground; the top two sides of the double-layer airbag are respectively provided with first metal pressure strips pressed against the first pressing edges and pre-embedded and fixed in the ground; the top two sides of the double-layer airbag are respectively provided with first metal pressure strips. A set of first buckles for fastening to the grid cover plate is provided. Multiple sets of second buckles are provided on both sides of the double-layered airbag, corresponding to the junctions of two adjacent inner airbags and for fastening to the grid cover plate. As each set of second buckles is released from the grid cover plate, the inner airbag above that second buckle can expand after inflation to adjust its height. The grid cover plate is initially embedded in a first mounting groove. A locking element is provided between the grid cover plate and the first mounting groove to prevent the grid cover plate from shaking. The locking element must be released before the double-layered airbag is inflated. The solar power supply device also includes a first water level sensor and a buzzer mounted on a bracket. The first water level sensor and the buzzer are respectively connected to the controller signal.

[0015] By adopting the above technical solution, during flood prevention, the operators of entrances and exits (including subway entrances and exits, tunnel entrances and exits, underground parking garage entrances and exits, underground shopping mall entrances and exits, etc.) first engage the locking mechanism. After the first water level sensor detects an increase in the ground water level, the controller controls the air pump to inflate the double-layer airbags. After the double-layer airbags are inflated, the bottom is pressed against the first mounting groove, and the top drives the grille cover plate to push upwards. The sides are pressed against the side walls of the entrance and exit to achieve the function of flood prevention and waterproofing. At the same time, when flood prevention is not required, the opening of the first mounting groove is equipped with a grille cover plate to allow vehicles to pass through.

[0016] A further feature of this invention is that the external airbag includes a lower airbag with its top sides folded outwards along the length direction, and an upper airbag with its bottom sides folded outwards along the length direction and connected to the folded-out portions of the lower airbag. The connection between the lower airbag and the upper airbag forms a first pressing edge portion. The height of the lower airbag is lower than the height of the first mounting groove. The upper airbag includes two symmetrically arranged first side airbags, two symmetrically arranged second side airbags connected between the first side airbags, and a first top airbag disposed on top of the two first side airbags and the two second side airbags. The upper airbag is rectangular in shape after inflation, and the bottom of the first side airbags folds outwards.

[0017] By adopting the above technical solution, the upper bladder includes two symmetrically arranged first side bladders, two symmetrically arranged second side bladders connected between the first side bladders, and a first top bladder on top of the two first side bladders and the two second side bladders, so that the upper bladder is rectangular after being inflated, which gives the double-layer airbag good pressure bearing capacity and can improve the sealing performance of the double-layer airbag when it is used for flood prevention and water blocking.

[0018] The purpose of this invention is to provide a smart flood control structure that has the functions of rapid response, wear resistance, and efficient flood control and water blocking.

[0019] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a smart flood control structure, comprising a flood control wall located on the bank of a river or sea and having multiple arranged second mounting slots on its top, an inflatable expansion module, a closed cover plate, and lighting lamps arranged on the top of the flood control wall and located between adjacent second mounting slots; the double-layer airbag is disposed in the second mounting slot, the upper half of the double-layer airbag protruding from the second mounting slot after inflation and being rectangular in shape, and the periphery of the double-layer airbag is provided with a second pressing edge; second metal parts are respectively provided on both sides of the second mounting slot, pressed against the second pressing edge and pre-embedded and fixed in the flood control wall. The lighting fixture includes a pressure strip; the lamp post of the lighting lamp is installed on the top of the flood control wall, and the lamp post has insertion slots on both sides; the two sides of the double-layer airbag are embedded and pressed into the two insertion slots after inflation; the top two sides of the double-layer airbag are provided with third buckles for fastening to the sealing cover; the sealing cover is embedded in the second mounting slot in the initial state, and an anti-detachment component is provided between the sealing cover and the second mounting slot to prevent the sealing cover from shaking. The anti-detachment component automatically detaches during the inflation of the double-layer airbag; the solar power supply device also includes a second water level sensor installed on the bracket, and the second water level sensor is signal connected to the controller.

[0020] By adopting the above technical solution, when carrying out flood control on the banks of rivers and seas, the conventional technical solution is to increase the height of the flood control wall, but this will greatly affect the scenery of the river and sea banks. In this solution, the double-layer airbags are hidden in the flood control wall in advance, and the top is sealed with a cover plate. After the second water level sensor detects that the water level has risen to a certain level, the controller first controls the air pump to inflate the double-layer airbags. After the double-layer airbags are inflated, the bottom is pressed against the second installation groove, and the top drives the sealing cover plate to push upward, and the two sides are pressed against the insertion grooves on both sides of the lamp post of the lighting, so as to realize the flood control and water blocking function.

[0021] A further feature of this invention is that a connecting ring is provided at the corner of the top of the double-layer airbag, and a hook is provided at a corresponding position on the lamp post of the lighting lamp to connect with the connecting ring after the double-layer airbag is inflated.

[0022] By adopting the above technical solution, by setting hooks on the lamp posts of the lighting lamps and by setting connecting rings at the corners of the top of the double-layer airbags, the pressure-bearing capacity of the double-layer airbags after inflation is improved after the hooks and connecting rings are connected. Furthermore, if a double-layer airbag is difficult to inflate due to damage to the air pump, the connection of the hooks and connecting rings can also be used to enable the double-layer airbags to play a certain role in flood prevention and water blocking.

[0023] The purpose of this utility model is to provide a smart fencing structure that features rapid response, durability, and ease of assembly and disassembly.

[0024] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a smart enclosure structure, including multiple detachably connected mounting bases and an inflatable expansion module; the mounting base includes two side-by-side support tubes and multiple reinforcing rods with both ends installed between the support tubes, and the support tubes of two adjacent mounting bases are inserted into each other; the bottom sides of the double-layer airbag are provided with multiple fourth buckles for fastening to the mounting base, and the double-layer airbag is trapezoidal after inflation.

[0025] By adopting the above technical solution, when using the inflatable expansion module for fencing, the mounting bases can be disassembled to facilitate transportation. After the mounting bases are assembled, the fourth buckle of the double-layer airbag of the inflatable expansion module is installed on the mounting base, and then it is inflated by an air pump. Finally, it is used for temporary fencing after expansion.

[0026] A further feature of this invention is that the support tube is provided with a plurality of fastening grooves, and the two ends of the reinforcing rod are respectively provided with two fastening parts that can be embedded in the fastening grooves during pressing and are fastened in the fastening grooves after being released.

[0027] By adopting the above technical solution, the support tube and reinforcing rod of the mounting base can be detachably fastened together, which facilitates transportation after disassembly and facilitates assembly during installation. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1: An inflatable expansion module, such as Figures 1 to 3 As shown, it includes a bracket 11, an air pump 12 mounted on the bracket 11, a solar power supply device 13 mounted on the bracket 11 and supplying power to the air pump 12, a double-layer airbag 14, and an inflation tube 15 connecting the air pump 12 and the double-layer airbag 14.

[0032] like Figures 1 to 3 As shown, the solar power supply device 13 includes a solar panel 131 mounted on a bracket 11, a controller 132 mounted on a bracket 11, and a battery 133 mounted on a bracket 11. The controller 132 is connected to the solar panel 131, the battery 133, and the air pump 12. The solar panel 131 supplies power to the battery 133, and the battery 133 supplies power to the air pump 12.

[0033] like Figures 1 to 3 As shown, the double-layered airbag 14 includes an outer airbag 141 and an inner airbag 142 disposed within the outer airbag 141. The inner airbag 142 is provided with an inflation connector 144 that extends out of the outer airbag 141 and connects to the inflation tube 15. During the inflation of the inner airbag 142, the outer airbag 141 is inflated. The outer airbag 141 includes a woven outer layer 1411 and a rubber inner layer 1412 laminated within the woven outer layer 1411. The outer airbag 141 can be made by sewing together pieces of cut material, so that after the inner airbag 142 is inflated, the outer airbag 141 can inflate to the desired shape. At the same time, a labeling strip 16 (which can be a reflective strip or a strip with a specific label) is provided around the periphery of the outer airbag 141 for identification. Meanwhile, multiple inner airbags 142 are provided, and the multiple inner airbags 142 are stacked. The inflation connector 144 is connected to the lowest inner airbag 142, and a connecting connector 143 is provided between any two inner airbags 142.

[0034] Implementation effect: The composite structure of the outer woven fabric layer 1411 and the inner rubber layer 1412 of the outer airbag 141, combined with the active expansion mechanism of the inner airbag 142, can disperse stress concentration and improve the overall compressive strength. When the inner airbag 142 is inflated, it drives the outer airbag 141 to expand synchronously through the inflation connector 144, forming a graded pressure bearing mode, avoiding the single-layer structure from cracking due to local overload and reducing the risk of failure. Moreover, the combination of the solar power supply device 13 and the inflation pump 12 achieves energy self-sufficiency. Finally, it has the functions of rapid response and wear resistance during the inflation process of the double-layer airbag 14.

[0035] Solar panel 131 converts solar energy into electrical energy and stores it through battery 133, enabling air pump 12 to maintain an inflatable state for an extended period, ensuring that the double-layer airbag 14 remains inflated after inflation. An identification strip 16 is provided around the periphery of the outer airbag 141, and different markings can be set on the strip 16 according to different usage environments for reminder purposes. Multiple inner airbags 142 are arranged in a stacked configuration. When combined with an external structure to limit the maximum inflation height of the outer airbags 141, the maximum height of the double-layer airbag 14 can be adjusted after the inflated inner airbags 142 within this height range.

[0036] Example 2: A smart flood control structure, such as Figures 4 to 7 As shown, it includes a ground 21 with a first mounting groove 211 located at the entrance / exit, an inflatable expansion module 1 as described in Embodiment 1, and a grid cover plate 22. The structure of the inflatable expansion module 1 in Embodiment 1 will be further defined.

[0037] like Figures 4 to 7 As shown, the double-layer airbag 14 is set in the first mounting groove 211. The upper part of the double-layer airbag 14 protrudes from the first mounting groove 211 after inflation and is in the shape of a cuboid. The double-layer airbag 14 has a first pressing edge 1415 on both sides along its length. The height of the lowermost inner airbag 142 after inflation is 30-50 cm higher than the first mounting groove 211. The two sides of the double-layer airbag 14 after inflation are pressed against the two side walls of the entrance and exit. The first metal pressure strip 23 is respectively set on both sides of the first mounting groove 211, pressed against the first pressing edge 1415 and pre-embedded and fixed in the ground 21. The first metal pressure strip 23 is fixed by the concrete poured at the ground.

[0038] like Figures 4 to 7 As shown, the top two sides of the double-layer airbag 14 are provided with a set of first buckles 145 for fastening to the grid cover plate 22. The two sides of the double-layer airbag 14 are provided with multiple sets of second buckles 146 corresponding to the junction of two adjacent inner airbags 142 and for fastening to the grid cover plate 22. As each set of second buckles 146 is released from the grid cover plate 22, the inner airbag 142 located above the second buckle 146 can expand after inflation to adjust the height after expansion.

[0039] like Figures 4 to 7 As shown, the grille cover 22 is embedded in the first mounting groove 211 in the initial state. A locking member 24 is provided between the grille cover 22 and the first mounting groove 211 to prevent the grille cover 22 from shaking. The locking member 24 includes a connecting sleeve pre-embedded and fixed in the ground 21, and a fixing bolt (not specifically marked in the figure) threaded through the grille cover 22 and connected in the connecting sleeve. The locking member 24 needs to be released before the double-layer airbag 14 is inflated.

[0040] like Figures 4 to 7As shown, the external airbag 141 includes a lower airbag 1413 with its top side folded outwards along the length direction, and an upper airbag 1414 with its bottom side folded outwards along the length direction and connected to the folded-out portion of the lower airbag 1413. The connection between the lower airbag 1413 and the upper airbag 1414 forms a first pressing edge portion 1415. The height of the lower airbag 1413 is lower than the height of the first mounting groove 211. The upper airbag 1414 includes two symmetrically arranged first side airbags 14141, two symmetrically arranged second side airbags 14142 respectively connected between the first side airbags 14141, and a first top airbag 14143 disposed on top of the two first side airbags 14141 and the two second side airbags 14142. After inflation, the upper airbag 1414 is rectangular, and the bottom of the first side airbags 14141 folds outwards.

[0041] like Figures 4 to 7 As shown, the solar power supply device 13 also includes a first water level sensor 134 and a buzzer 135 mounted on the bracket 11. The first water level sensor 134 and the buzzer 135 are respectively connected to the controller 132. When the first water level sensor 134 detects a rise in water level, the controller 132 controls the buzzer 135 to sound an alarm.

[0042] Implementation effect: During flood prevention, at entrances and exits (including subway entrances and exits, tunnel entrances and exits, underground parking garage entrances and exits, underground shopping mall entrances and exits, etc.), the operator first contacts the locking part 24 to lock. After the first water level sensor 134 detects the increase in the water level on the ground 21, the controller 132 controls the air pump 12 to inflate the double-layer airbag 14. After the double-layer airbag 14 is inflated, the bottom is pressed against the first mounting groove 211, the top drives the grille cover plate 22 to push upward, and the two sides are pressed against the two side walls of the entrance and exit to achieve the function of flood prevention and waterproofing. At the same time, when flood prevention is not required, the opening of the first mounting groove 211 is provided with a grille cover plate 22 to allow vehicles to pass through.

[0043] The upper bladder 1414 includes two symmetrically arranged first side bladders 14141, two symmetrically arranged second side bladders 14142 respectively connected between the first side bladders 14141, and a first top bladder 14143 disposed on top of the two first side bladders 14141 and the two second side bladders 14142. This makes the upper bladder 1414 rectangular after inflation, giving the double-layer airbag 14 good pressure bearing capacity and improving the sealing performance of the double-layer airbag 14 when it is used for flood prevention and water blocking.

[0044] Example 3: A smart flood control structure, such as Figures 8 to 10As shown, the system includes a flood control wall 31 located on the bank of a river or sea and having multiple second mounting slots 311 arranged on its top, an inflatable expansion module 1, a sealing cover 32, and lighting lamps 33 arranged on the top of the flood control wall 31 and located between adjacent second mounting slots 311. The structure of the inflatable expansion module 1 in Embodiment 1 will be further defined.

[0045] like Figures 8 to 10 As shown, the double-layer airbag 14 is disposed within the second mounting groove 311. The upper half of the double-layer airbag 14, after inflation, protrudes from the second mounting groove 311 and is rectangular in shape. A second pressing edge 1416 is provided around the periphery of the double-layer airbag 14. Second metal pressure strips 34, which are pressed against the second pressing edge 1416 and pre-embedded and fixed within the flood control wall 31, are respectively provided on both sides of the second mounting groove 311. The lamp post 331 of the lighting lamp 33 is disposed at the top of the flood control wall 31, and insertion slots 332 are formed on both sides of the lamp post 331. The two sides of the double-layer airbag 14, after inflation, are embedded and pressed against the two insertion slots 332. Third buckles 147 are provided on both sides of the top of the double-layer airbag 14 for fastening onto the closed cover plate 32. In its initial state, the sealing cover 32 is embedded in the second mounting groove 311. An anti-detachment component 35 (composed of an arc-shaped limiting groove at the second mounting groove 311 and an arc-shaped protrusion on the side of the sealing cover 32) is provided between the sealing cover 32 and the second mounting groove 311 to prevent the sealing cover 32 from shaking. During the inflation of the double-layer airbag 14, the anti-detachment component 35 automatically detaches. Simultaneously, the solar power supply device 13 also includes a second water level sensor 136 mounted on the bracket 11, which is signal-connected to the controller 132.

[0046] like Figures 8 to 10 As shown, a connecting ring 148 is provided at the corner of the top of the double-layer airbag 14, and a hook 333 is provided on the lamp post 331 of the lighting lamp 33 to connect with the connecting ring 148 after the double-layer airbag 14 is inflated.

[0047] Implementation effect: When carrying out flood control on the banks of rivers and seas, the conventional technical solution is to increase the height of the flood control wall 31, but this has a great impact on the scenery of the river and sea banks. In this solution, the double-layer airbag 14 is hidden in the flood control wall 31 in advance, and the top is sealed by a cover plate. After the second water level sensor 136 detects that the water level has risen to a certain level, the controller 132 controls the air pump 12 to inflate the double-layer airbag 14. After the double-layer airbag 14 is inflated, the bottom is pressed against the second mounting groove 311, and the top drives the sealing cover plate to push upward, and the two sides are pressed against the insertion grooves on both sides of the lamp post 331 of the lighting lamp 33, so as to realize the flood control and water blocking function.

[0048] By setting a hook 333 on the lamp post 331 of the lighting lamp 33 and a connecting ring 148 at the corner of the top of the double-layer airbag 14, the pressure resistance of the double-layer airbag 14 after inflation is improved after the hook 333 and the connecting ring 148 are connected. If a double-layer airbag 14 is difficult to inflate due to damage to the air pump 12, the connection of the hook 333 and the connecting ring 148 can be used to enable the double-layer airbag 14 to play a certain role in flood prevention and water blocking.

[0049] Example 4: A smart fencing structure, such as Figures 11 to 13 As shown, it includes multiple detachably connected mounting bases 41 and the inflatable expansion module 1 in Embodiment 1. The structure of the inflatable expansion module 1 in Embodiment 1 is further defined.

[0050] like Figures 11 to 13 As shown, the mounting base 41 includes two side-by-side support tubes 411 and multiple reinforcing rods 412 with both ends installed between the support tubes 411. The support tubes 411 of two adjacent mounting bases 41 are interlocked. Multiple fourth buckles 149 for fastening onto the mounting base 41 are provided on both sides of the bottom of the double-layer airbag 14. After inflation, the double-layer airbag 14 forms a trapezoidal shape (mainly because the outer airbag 141 can be made by sewing together pieces of cut material). Multiple fastening grooves 4111 are provided on the support tubes 411. Two fastening parts 4121 are symmetrically provided at both ends of the reinforcing rods 412, which can be embedded in the fastening grooves 4111 during pressing and are fastened in the fastening grooves 4111 after release.

[0051] Implementation Results: When using the inflatable expansion module 1 for fencing, the mounting base 41s are detachable from each other, facilitating transportation. After assembling the mounting base 41s, the fourth buckle 149 of the double-layer airbag 14 of the inflatable expansion module 1 is installed on the mounting base 41, and then inflated by the air pump 12, ultimately inflating for temporary fencing. The support tube 411 and reinforcing rod 412 of the mounting base 41 are detachably fastened together, facilitating transportation after disassembly and assembly during installation.
