Abstract

This invention relates to the field of flood control board technology and discloses a foldable emergency flood control board, comprising: a water-retaining fabric; a preliminary splicing assembly disposed on both sides of the water-retaining fabric for initially connecting two adjacent water-retaining fabrics; a folding support assembly for folding and unfolding the water-retaining fabric; and a splicing support assembly disposed on both sides of the folding support assembly for connecting two adjacent water-retaining fabrics. The water-retaining fabric includes a waterproof outer layer, a detection layer, and a waterproof inner layer distributed sequentially. This invention uses a scissor-type frame to link the uprights and crossbars. After unfolding, the unfolding is limited by an unfolding retaining ring and locked by an unfolding indexing pin, enabling rapid deployment and resistance to deformation. When folded, the crossbar rotates around the rear base to be parallel to the uprights, resulting in a small size and easy storage. Furthermore, through the preliminary splicing assembly and the splicing support assembly, along with steel wire ropes sewn to the back of the water-retaining fabric and secured by binding holes, lower binding grooves, and side binding grooves, it resists water pressure and prevents collapse.

Description

Technical Field

[0001] This invention relates to the field of flood control board technology, specifically a foldable emergency flood control board. Background Technology

[0002] With the intensification of global climate change and the frequent occurrence of extreme heavy rainfall events, flood disasters such as urban flooding, river overflows, and levee breaches are becoming more frequent and sudden, placing higher demands on emergency flood control and rapid response in key areas such as urban communities, transportation hubs, underground spaces, and levee shorelines. Currently, flood prevention and rescue efforts still rely primarily on traditional methods such as sandbags, earth and rock dikes, fixed retaining walls, and simple assembled barriers. These methods have significant shortcomings in terms of rapid response, portability and storage, sealing and waterproofing, reusability, and adaptability to complex scenarios, making it difficult to meet the practical needs of modern emergency flood control. Traditional sandbag construction requires a large amount of manpower and time, with low efficiency in filling, transporting, and stacking. It also results in poor sealing density, easy leakage, high post-flood cleanup and waste disposal costs, and the sandbags cannot be reused. Earth-rock cofferdams and concrete retaining walls have long construction cycles, occupy a large amount of space, and lack mobility. They are only suitable for reinforcing fixed dikes and are not suitable for temporary emergency scenarios such as street intersections, underground entrances and exits, and weak sections of the shoreline. Existing rigid modular flood control panels are mostly modular, with cumbersome splicing procedures, insufficient sealing reliability, large storage and transportation volume, and slow deployment and dismantling. They are poorly adaptable to complex conditions such as narrow spaces, irregular intersections, and slopes, making it difficult to achieve rapid sealing and efficient water blocking.

[0003] With the advancement of urban resilience building and the modernization of emergency management, flood control equipment is being upgraded towards lightweight, modular, rapid, and reusable designs. Foldable structures, with their advantages of small folded size, convenient unfolding, single-person operation, and adaptability to multiple scenarios, have become an important research and development direction for emergency flood control equipment.

[0004] However, existing folding flood barriers generally suffer from insufficient structural rigidity, ineffective water-stop sealing, poor stability against water flow impact, weak connection strength, and insufficient durability. Under high water levels and high flow velocities, they are prone to deformation, overturning, or leakage, failing to guarantee a continuous and reliable flood control effect. To overcome the technical shortcomings of traditional flood control measures and existing folding devices, there is an urgent need to develop a folding emergency flood barrier that is portable when folded, unfolds quickly, has reliable sealing, is impact-resistant and stable, and is reusable. This would enable rapid deployment and efficient sealing in confined spaces, temporary locations, and sudden emergencies, improving the emergency response capabilities of urban and rural grassroots organizations and professional rescue teams, and reducing flood damage. Summary of the Invention

[0011] As a further embodiment of the present invention, the upper and lower rotating seats are internally threaded with an upper indexing pin and a lower indexing pin, and the upper and lower indexing pins are respectively inserted into pin holes opened at the ends of the upper and lower splicing plates.

[0012] As a further embodiment of the present invention, the detection layer is a serpentine wire loop that completely covers the water-blocking cloth. An electrical control box is provided on one side of the foldable support assembly. The electrical control box contains a battery, a wireless module, and a microcontroller that are electrically connected to the serpentine wire loop.

[0013] As a further embodiment of the present invention, an automatic alarm system is also included, the automatic alarm system including a liquid level sensor, the liquid level sensor being installed at the top of a pole located in the middle position, and the liquid level sensor passing through and being fixedly connected to the water-blocking cloth, the liquid level sensor being electrically connected to the electrical control box.

[0016] Compared with the prior art, the present invention provides a foldable emergency flood control board, which has the following beneficial effects: 1. The emergency flood control board has a convenient and stable structure: the folding support component links the uprights and crossbars through a scissor frame. After unfolding, it is limited by the unfolding retaining ring and locked by the unfolding indexing pin, which allows for rapid deployment and resistance to deformation. When storing, the crossbar rotates around the rear base until it is parallel to the uprights, and it is small in size and easy to store.

[0017] 2. Accurate early warning for water barrier damage: The water barrier has a built-in serpentine wire loop, and the microcontroller monitors the loop resistance with a microampere-level constant current source. When damaged, the circuit is broken, triggering an alarm and locating the problem. This distinguishes between "flooding" and "damage" to avoid false alarms.

[0018] 3. The emergency flood control panels are firmly and reliably spliced ​​together: the initial splicing components are glued together by overlapping the male and female hook and loop fasteners. The upper and lower splicing plates of the splicing support components are fixed by the upper and lower rotating seats and the upper and lower indexing pins. They are also fixed by steel wire ropes sewn to the back of the water-blocking cloth through binding holes, lower binding grooves and side binding grooves to resist water pressure and prevent collapse.

[0019] 4. Emergency flood control board is equipped with overflow protection: The liquid level sensor detects the water level, and when it is close to overflow, the electrical control box controls the electromagnetic water valve to open, and the drain pipe drains water through the drain hole. After the water level drops, it closes to prevent collapse due to overpressure. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0024] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] Please see Figures 1-14 As shown, a foldable emergency flood control board includes a water-blocking cloth 1, a preliminary splicing assembly 4, a foldable support assembly 2, and a splicing support assembly 3, etc.

[0027] Specifically, the water-blocking cloth 1 includes a waterproof outer layer 101, a detection layer 102 and a waterproof inner layer 103 arranged in sequence. The detection layer 102 is a serpentine wire loop 10201, which completely covers the water-blocking cloth 1. An electrical control box 10 is provided on one side of the foldable support assembly 2. The electrical control box 10 contains a battery, a wireless module and a microcontroller that are electrically connected to the serpentine wire loop 10201. The waterproof outer layer 101 and the waterproof inner layer 10 are made of polyvinyl chloride mesh fabric, which is not only high in strength, but also has strong wear resistance, waterproof and anti-aging properties.

[0028] In addition, the wire connector between the electrical control box 10 and the water-blocking cloth 1 is a waterproof connector to prevent water from entering the wire connector and causing a short circuit.

[0029] The serpentine conductor loop 10201 is made of copper-platinum alloy wire or printed conductive ink (silver paste / carbon paste), preferably printed conductive ink (silver paste / carbon paste). The flexibility and bending resistance of printed conductive ink (silver paste / carbon paste) far exceed that of copper-platinum alloy wire, making it more suitable for fabric-based materials. It is heat-pressed and fixed to one side of the waterproof inner layer 103, and then the other side is heat-pressed and bonded to the waterproof outer layer 101. The serpentine conductor loop 10201 runs through the entire fabric surface, forming a conductive circuit.

[0030] Under normal conditions, the circuit resistance is extremely low (<10 ohms). Once any part of the flood barrier is punctured, torn, or broken, the wire at that point will inevitably break, and the circuit resistance will become infinite. Damage will result in a broken wire, which will trigger an alarm, allowing the location to be determined and the emergency flood barrier replaced promptly.

[0031] Location can be obtained by installing GPS / BeiDou modules or by assigning an ID number to each emergency flood control board, thus facilitating rapid location of the emergency flood control board's location information.

[0032] Each emergency flood control panel's microcontroller continuously monitors the detection circuit resistance via an extremely weak constant current source (microampere level).

[0033] The alarm condition is: if a circuit break is continuously detected for more than 1 second, it is judged that the water barrier cloth 1 is damaged.

[0034] However, if the flood completely submerges the slab but the fabric remains intact, the wires will still conduct electricity and no alarm will be triggered. Only report a genuine tear, thus distinguishing between "flooding" and "damage".

[0035] Please refer to the tear detection system logic. Figure 14 .

[0036] The foldable support assembly 2 works in conjunction with the shielding cloth. The foldable support assembly 2 includes at least three sets of uprights 201 and horizontal bars 202. Four sets of scissor frames 203 are arranged between the three sets of uprights 201 and horizontal bars 202 to realize that the water-blocking cloth 1 folds and unfolds as the uprights 201 and horizontal bars 202 are folded. The specific structure is as follows: a rear base 5 is fixedly installed at the bottom of the upright 201, and the rear base 5 is hinged to the crossbar 202. An extension base 6 is fixedly installed at the end of the crossbar 202. The water-blocking cloth 1 is bonded and fixed to the extension base 6 and the end of the upright 201. Therefore, the crossbar 202 rotates and folds inside the rear base 5 until it is parallel to the upright 201. The ends of the uprights 201 and the crossbars 202 near the rear base 5 are both fixed with mounting bases 204 by bolts. The ends of the uprights 201 and the crossbars 202 away from the rear base 5 are both slidably mounted with sliding blocks 205. The sliding blocks 205 can move up and down along the uprights 201 or the crossbars 202. The scissor frame 203 is hinged to the two adjacent mounting bases 204 and sliding blocks 205. Therefore, the folding connection of the three sets of uprights 201 and the three sets of crossbars 202 is completed by the scissor frame 203. In addition, an unfolding retaining ring 207 is fixedly installed on one side of the upright 201 located in the middle position to limit the slide 205. The unfolding retaining ring 207 is used to limit the position of the slide 205, that is, to limit the position of the three sets of uprights 201 after unfolding. An unfolding indexing pin 206 is threadedly installed on one side of the slide 205 of the upright 201 located in the middle position. The end of the unfolding indexing pin 206 passes through the slide 205 and is inserted into the pin hole opened in the upright 201 for fixing the position of the slide 205. Therefore, after the four sets of scissor frames 203 are deployed, the three sets of uprights 201 and the three sets of crossbars 202 are also deployed simultaneously, and the water-blocking cloth 1 is also deployed. The slide 205 is blocked and limited by the deployment retaining ring 207, and the deployment action is completed at this time. Then, the position of the slide 205 is locked and fixed by turning the deployment indexing pin 206, which further improves the stability of the folding support component 2 after deployment.

[0037] When assembling two adjacent emergency flood control panels, they are connected by preliminary splicing components 4. The preliminary splicing components 4 are located on both sides of the water-blocking cloth 1 and are used to initially connect the two adjacent water-blocking cloths 1. The initial splicing component 4 includes a male hook and loop fastener 402 and a female hook and loop fastener 401 that cooperate with each other. The male hook and loop fastener 402 and the female hook and loop fastener 401 are respectively installed on the front and back sides of the water-blocking cloth 1. Therefore, when connecting two water-blocking cloths 1, the overlapping parts of the two adjacent water-blocking cloths 1 are partially overlapped, and then the male hook and loop fastener 402 and the female hook and loop fastener 401 are glued to each other, so that the overlapping parts of the water-blocking cloths 1 are connected and fixed.

[0038] However, during the water blocking process, due to the water pressure, the water blocking cloth 1 is easily broken if it is only fixed by the male hook and loop fastener 402 and the female hook and loop fastener 401. Therefore, a steel wire rope 302 is set for support. The steel wire rope 302 is sewn on the back of the water blocking cloth 1, and the splicing support component 3 is used to support the bolted steel wire rope 302. Specifically, the splicing support component 3 is located on both sides of the folding support component 2. The splicing support component 3 includes an upper splicing plate 301, a lower splicing plate 303, an upper rotating seat 30102, and a lower rotating seat 30302. The upper splicing plate 301 and the lower splicing plate 303 are respectively rotatably installed on one side of one of the uprights 201 and one of the rear stop bases 5; The upper rotating seat 30102 and the lower rotating seat 30302 are rotatably mounted on one side of another upright 201. The upper rotating seat 30102 and the lower rotating seat 30302 are respectively engaged with the upper splicing plate 301 and the lower splicing plate 303. The upper rotating seat 30102 and the lower rotating seat 30302 are internally threaded with upper indexing pin 30103 and lower indexing pin 30303, and the upper indexing pin 30103 and the lower indexing pin 30303 are respectively inserted into the pin holes opened at the ends of the upper splicing plate 301 and the lower splicing plate 303. Therefore, by unfolding the upper splicing plate 301 and the lower splicing plate 303 respectively, the upper splicing plate 301 and the lower splicing plate 303 are respectively inserted into the upper rotating seat 30102 and the lower rotating seat 30302. Then, by rotating the upper indexing pin 30103 and the lower indexing pin 30303, the upper indexing pin 30103 and the lower indexing pin 30303 are respectively screwed into the upper splicing plate 301 and the lower splicing plate 303, thereby completing the fixing of the upper splicing plate 301 and the lower splicing plate 303. Then, a lower storage groove 30301 is provided inside the lower splicing plate 303. A transverse pull plate 304 is rotatably installed inside the lower storage groove 30301. A lower binding groove 30401 and a side binding groove 30402 are provided at the top and end of the transverse pull plate 304, respectively. The lower binding groove 30401 and the side binding groove 30402 are used for winding and fixing one end of the wire rope 302. The upper splicing plate 301 has a binding hole 30101 inside, which is used for winding and fixing the other end of the wire rope 302. Thus, the two ends of the steel wire rope 302 are wrapped and fixed through the lower binding groove 30401, the side binding groove 30402, and the binding hole 30101, and the steel wire rope 302 is used to fix and support the side of the water barrier cloth 1.

[0039] Furthermore, since both the upper rotating seat 30102 and the lower rotating seat 30302 are rotatably connected to the upright 201, adjacent emergency flood control panels can be connected not only in a straight line but also in a curved manner (e.g., Figure 9 As shown in the figure, it is used to meet the needs of different water blocking situations.

[0040] One side of the horizontal pull plate 304 is fixed with a pull plate support foot 30403 by bolts. The pull plate support foot 30403 is in contact with the ground, which can not only provide auxiliary support for the end of the horizontal pull plate 304, but also block and limit the horizontal pull plate 304 when it is fastened to the lower storage slot 30301, so as to facilitate the storage operation of the horizontal pull plate 304.

[0041] Furthermore, during the use of the emergency flood control board, if too much water is blocked and gradually overflows the board, the overflowing floodwater will not only cause the floodwater to flow to the other side, but will also fail to block the overflowing floodwater. The resulting pressure increase can easily damage the emergency flood control board, causing it to collapse due to overpressure. Therefore, an automatic alarm system is installed to autonomously release floodwater before overflow, preventing overpressure. The automatic alarm system includes a liquid level sensor 7 (model WIFS-IR2102DM can be used). The liquid level sensor 7 is installed at the top of the upright 201 located in the middle position, and passes through the water-blocking cloth 1 and is fixedly connected to it. The liquid level sensor 7 is electrically connected to the electrical control box 10. The liquid level sensor 7 detects whether there is water at the probe position. Two drainage holes 801 are opened on one side of the water-blocking cloth 1. Drainage pipes 8 are glued inside each drainage hole 801. Electromagnetic water valves 9 are installed at the ends of the drainage pipes 8, and the electromagnetic water valves 9 are electrically connected to the electrical control box 10.

[0042] Therefore, the level sensor 7 can detect whether the water blocked by the emergency flood control plate is overflowing. When it is close to overflowing, the electromagnetic water valve 9 is opened. At this time, the water blocked by the emergency flood control plate is discharged through the drain hole 801 and the drain pipe 8, which greatly reduces the flood overflow and prevents the emergency flood control plate from collapsing due to overpressure. When the level sensor 7 detects that the water blocked by the emergency flood control plate has dropped to the specified height, the solenoid water valve 9 is closed, and drainage stops.

[0043] It should be noted that the storage battery, wireless module, microcontroller, liquid level sensor 7, electromagnetic water valve 9, etc. involved in this application are all prior art. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0044] The usage involves the following steps: After the four sets of scissor frames 203 are deployed, the three sets of uprights 201 and the three sets of horizontal bars 202 are also deployed simultaneously, and the water-blocking cloth 1 is also deployed. The slide 205 is blocked and limited by the deployment retaining ring 207. At this time, the deployment action is completed. Then, the position of the slide 205 is locked and fixed by turning the deployment indexing pin 206. When assembling two adjacent emergency flood control boards, the two adjacent water-blocking cloths 1 are partially overlapped, and then the overlapping parts of the water-blocking cloths 1 are connected and fixed by the male hook and loop fastener 402 and the female hook and loop fastener 401. Then, unfold the upper splicing plate 301 and the lower splicing plate 303 respectively, so that the upper splicing plate 301 and the lower splicing plate 303 are respectively inserted into the upper rotating seat 30102 and the lower rotating seat 30302. Then, by rotating the upper indexing pin 30103 and the lower indexing pin 30303, the upper indexing pin 30103 and the lower indexing pin 30303 are respectively screwed into the upper splicing plate 301 and the lower splicing plate 303, thereby completing the fixation of the upper splicing plate 301 and the lower splicing plate 303. Then, through the lower binding groove 30401, the side binding groove 30402, and the binding hole 30101, the two ends of the wire rope 302 are wrapped and fixed, and the wire rope 302 completes the fixed support for the side of the water-blocking cloth 1.

[0045] Damage warning for water barrier 1: The microcontroller of each emergency flood control panel continuously monitors the circuit resistance through an extremely weak constant current source (microampere level). Under normal conditions, the circuit resistance is extremely small (<10 ohms). Once any part of the water barrier 1 is punctured, torn, or broken, the wire at that point will inevitably break, and the circuit resistance will become infinite. Damage will result in a wire break, which will trigger an alarm, allowing the location to be obtained and the emergency flood control panel to be replaced in a timely manner.

[0046] Flood overflow: The level sensor 7 detects whether the water blocked by the emergency flood control plate is overflowing. When it is close to overflowing, the solenoid water valve 9 is opened. At this time, the water blocked by the emergency flood control plate is discharged through the drain hole 801 and the drain pipe 8. When the level sensor 7 detects that the water blocked by the emergency flood control plate has dropped to the specified height, the solenoid water valve 9 is closed, and drainage stops.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
