According to the flood control device, the angle of the water baffle can be automatically or manually adjusted according to the change of the flood level so as to adapt to different flood levels, and the flood control capacity is improved. The arrangement of the inflation cavity and the water filling cavity enables the device to quickly respond when flood comes, the device is inflated and expanded to support the water baffle, and the device can be folded through drainage and deflation in a non-flood season, so that the occupation of land resources is reduced.

Description

Technical Field

[0001] This invention relates to the field of flood control equipment technology, specifically to a flood control and flood season control device. Background Technology

[0002] With the increasing frequency of global climate change and extreme weather events, many regions face severe flood threats. Traditional flood control measures, such as dikes and embankments, while playing a vital role in flood prevention and mitigation, often have limitations. For example, fixed-height flood control facilities may not be effective against floods exceeding standard levels, and may waste land resources during non-flood seasons. Flood walls, a key technology in this field, mainly include the following types:

[0003] Fixed flood walls: These walls have a fixed height and are suitable for areas where flood levels are relatively stable. However, their protective capacity is limited when encountering floods exceeding standard levels. Movable flood walls: Movable flood walls can be adjusted according to changes in flood levels, but the adjustment process often requires manual intervention, which is complex and time-consuming. Water-filled flood walls: Water-filled flood walls adjust their stability by filling or draining water, but they pose certain safety hazards in practical applications and occupy land resources during non-flood seasons. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a flood control and flood season prevention device.

[0006] The flood control and flood season protection device of this invention includes a base, a first water-blocking plate, a support bag, a gas generator, and a water injection pipe. The first water-blocking plate is disposed on the base, and its first end is rotatably connected to the base so as to be foldable relative to the base. The support bag is disposed between the base and the first water-blocking plate. The support bag includes an outer bag and an inner bag. The outer bag is connected to the top surface of the base and the back surface of the first water-blocking plate, respectively. The inner bag is disposed inside the outer bag and defines an inflation chamber between the inner bag and the outer bag. The inner bag has a water filling chamber. When the inflation chamber is inflated, the support bag supports the first water-blocking plate to rotate relative to the base by a preset angle to block floods. The gas generator is connected to the inflation chamber and is used to fill the inflation chamber with gas. The water injection pipe passes through the support bag and is connected to the water filling chamber and is used to fill the water filling chamber with water.

[0007] In some embodiments, the cross-section of the support bag is generally triangular, and the outer bag includes a first outer surface, a second outer surface, and a third outer surface. The first outer surface is attached to the top surface of the base, and the second outer surface is attached to the back surface of the first baffle.

[0008] In some embodiments, the support bag is provided with a first safety valve, which is connected to the inflation chamber. When the air pressure in the inflation chamber exceeds a preset value, the first safety valve opens.

[0009] In some embodiments, the support bag is provided with an overflow valve and a drain valve. The overflow valve is located at the top of the support bag and communicates with the water filling chamber. When the water level in the water filling chamber exceeds a preset height, the overflow valve opens. The drain valve is located at the bottom of the support bag and communicates with the water filling chamber to drain the water in the water filling chamber.

[0010] In some embodiments, the flood control device further includes a return spring, the first end of which is connected to the base and the second end of which is connected to the first baffle plate. The return spring is used to drive the first baffle plate to rotate relative to the base after the support bag is vented, so as to fold the first baffle plate.

[0011] In some embodiments, the flood control and flood season protection device further includes a water injection assembly, which includes a rotating shaft, a water wheel, a cam, an elastic water bladder, and a water suction pipe. The rotating shaft is rotatably mounted on the base in a vertical direction. The water wheel is mounted on the rotating shaft. The cam is mounted on the rotating shaft. The elastic water bladder is mounted on the base. One end of the water suction pipe is connected to the elastic water bladder. The water injection pipe is connected to the elastic water bladder. The water wheel is used to rotate when driven by floods to drive the cam to rotate. The rotation of the cam is used to intermittently squeeze the elastic water bladder so that the water suction pipe draws water into the elastic water bladder and delivers the water to the filling chamber through the water injection pipe.

[0012] In some embodiments, the water suction pipe is provided with a first one-way valve, the opening of the first one-way valve facing the elastic water bladder, and the water injection pipe is provided with a second one-way valve, the opening of the second one-way valve facing away from the elastic water bladder.

[0013] In some embodiments, the flood control device further includes a second baffle plate, the first baffle plate having a receiving cavity and an opening, the opening being located on the end face of a second end of the first baffle plate, the second baffle plate being slidably disposed in the receiving cavity so that the second baffle plate extends out of the receiving cavity relative to the first baffle plate through the opening.

[0014] In some embodiments, the first baffle plate has a groove on its water-facing surface, the second baffle plate has a slider, the slider is slidably fitted in the groove, the flood control device further includes a buoyancy airbag, the buoyancy airbag is connected to the slider, the gas generator is connected to the buoyancy airbag to inflate the buoyancy airbag, and the buoyancy airbag is provided with a second safety valve.

[0015] In some embodiments, a sealing ring is fitted onto the second baffle plate, and the outer edge of the sealing ring abuts against the inner wall of the receiving cavity.

[0016] The flood control device of this invention can automatically or manually adjust the angle of the flood barrier according to changes in flood water level to adapt to different flood levels and improve flood control capabilities. The inclusion of an air-filling chamber and a water-filling chamber allows the device to react quickly during floods, inflating to support the flood barrier, and can be retracted during non-flood seasons by draining and deflating, reducing land occupation. Compared to traditional fixed flood walls, this device can be folded away during non-flood seasons, saving land resources and reducing maintenance costs. In the event of a sudden flood, the gas generator can quickly provide gas, allowing the flood barrier to quickly take position, effectively reducing losses caused by flood disasters. Although it involves some technical operation, compared to the manual adjustment of movable flood walls, this device is much simpler to operate. Attached Figure Description

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The flood control and flood season protection device 100 of this invention includes a base 1, a first water-blocking plate 2, a support bag 3, a gas generator 4, and a water injection pipe 5. The first water-blocking plate 2 is disposed on the base 1, and its first end 201 is rotatably connected to the base 1, allowing it to be foldable relative to the base 1. The support bag 3 is disposed between the base 1 and the first water-blocking plate 2. The support bag 3 includes an outer bag 301 and an inner bag 302. The outer bag 301 is connected to the top surface of the base 1 and the back surface of the first water-blocking plate 2, respectively. The inner bag 302 is disposed inside the outer bag 301 and defines an inflation chamber 303 between the inner and outer bag 301. The inner bag 302 has a water filling chamber 3021. When the inflation chamber 303 is inflated, the support bag 3 supports the first water-blocking plate 2 to rotate relative to the base 1 by a preset angle to block floodwater. The gas generator 4 communicates with the inflation chamber 303 and is used to fill the inflation chamber 303 with gas. Water injection pipe 5 passes through the support bag 3 and is connected to the water filling chamber 3021, and is used to fill the water filling chamber 3021 with water.

[0025] In this embodiment of the flood control and flood season protection device 100, the base 1 serves as the foundation of the device, providing stability. A first water-blocking plate 2 is mounted on the base 1, with one end rotatably connected to it. This allows the water-blocking plate to be folded as needed, facilitating storage during non-flood seasons and saving land resources. A support bag 3 is located between the base 1 and the first water-blocking plate 2, consisting of an outer bag 301 and an inner bag 302. The outer bag 301 is connected to the top surface of the base 1 and the back surface of the first water-blocking plate 2, while the inner bag 302 is located inside the outer bag 301, forming an inflation chamber 303 between them. The inner bag 302 also contains a water-filling chamber 3021. A gas generator 4 fills the inflation chamber 303 with gas, causing the bag to inflate and supporting the first water-blocking plate 2 to rotate to a preset angle to block floodwaters. A water injection pipe 5 fills the water-filling chamber 3021 with water, increasing the stability of the bag.

[0026] The flood control device 100 of this invention can automatically or manually adjust the angle of the flood barrier according to changes in flood water level to adapt to different flood levels and improve flood control capabilities. The air-filling chamber 303 and water-filling chamber 3021 enable the device to react quickly during floods, inflating to support the flood barrier, and can be retracted during non-flood seasons by draining and deflating, reducing land occupation. Compared to traditional fixed flood walls, this device can be folded away during non-flood seasons, saving land resources and reducing maintenance costs. In the event of a sudden flood, the gas generator 4 can quickly provide gas, allowing the flood barrier to quickly take position, effectively reducing losses caused by flood disasters. Although it involves some technical operation, compared to the manual adjustment of movable flood walls, the operation of this device is simpler.

[0027] In some embodiments, the cross-section of the support bag 3 is generally triangular, and the outer bag 301 includes a first outer surface 3011, a second outer surface 3012, and a third outer surface 3013. The first outer surface 3011 is attached to the top surface of the base 1, and the second outer surface 3012 is attached to the back surface of the first water baffle 2. Figure 5 As shown, a triangle is a very stable geometric shape. This design increases the stability of the support bag 3, allowing it to better withstand the pressure from floodwaters when inflated or filled with water. The triangular cross-section of the support bag 3 distributes the force more evenly, helping to disperse the impact of floodwaters on the baffle plate and reducing the problem of excessive local pressure.

[0028] For example, the first outer surface 3011 is bonded to the top surface of the base 1, and the second outer surface 3012 is bonded to the back surface of the first water-retaining plate 2. The first outer surface 3011 adheres to the top surface of the base 1, ensuring no gaps between it and the base 1 when the bag is inflated or filled with water, thus improving overall stability. The second outer surface 3012 adheres to the back surface of the first water-retaining plate 2. This arrangement helps to better support the water-retaining plate when the bag inflates, allowing it to reach a predetermined angle and effectively block floodwaters.

[0029] The triangular cross-section increases the support of the bag, making the flood barrier more stable under flood pressure. This design allows the supporting bag 3 to adjust the amount of air and water filling as needed to adapt to different flood levels and pressures. Due to the uniform stress distribution, this design improves the reliability of the flood barrier and reduces the risk of damage caused by excessive local pressure. The triangular cross-section also makes the bag's structure relatively simple, facilitating inspection and maintenance.

[0030] In some embodiments, the support bag 3 is provided with a first safety valve (not shown in the figure), which is connected to the inflation chamber 303. When the air pressure in the inflation chamber 303 exceeds a preset value, the first safety valve opens.

[0031] The primary function of the first safety valve is to monitor the air pressure within the inflation chamber 303. When the air pressure exceeds a preset safety value, the first safety valve automatically opens, releasing excess gas to prevent damage or explosion of the inflatable bag due to excessive pressure. Therefore, the safety valve prevents the inflatable bag from rupturing or exploding due to excessive internal pressure, ensuring the structural integrity of the flood barrier under extreme conditions. By installing the safety valve, abnormal air pressure caused by operational errors or system malfunctions can be avoided, thereby improving the reliability of the entire flood control system. The automatic opening function of the safety valve provides an additional layer of protection for the flood barrier, automatically regulating air pressure even when unsupervised. By preventing damage to the inflatable bag material from excessive pressure, the service life of the flood barrier can be extended, reducing the frequency of maintenance and replacement.

[0032] In some embodiments, the support bag 3 is provided with an overflow valve (not shown in the figure) and a drain valve (not shown in the figure). The overflow valve is located at the top of the support bag 3 and communicates with the water filling chamber 3021. The overflow valve opens when the water level in the water filling chamber 3021 exceeds a preset height. The drain valve is located at the bottom of the support bag 3 and communicates with the water filling chamber 3021 to drain the water in the water filling chamber 3021.

[0033] An overflow valve, installed at the top of the support bag 3, is connected to the filling chamber 3021. Its main function is to automatically open when the water level in the filling chamber 3021 exceeds a preset height to drain excess water and prevent damage to the bag due to excessive water pressure. A drain valve, located at the bottom of the support bag 3, is also connected to the filling chamber 3021. The drain valve is used to manually or automatically drain water from the filling chamber 3021 during non-flood seasons or when it is necessary to reduce the water pressure inside the bag, so that the bag can contract and fold.

[0034] The overflow valve prevents excessive water level in the filling chamber 3021, avoiding damage to the support bag due to excessive water pressure and protecting the integrity of the entire flood control system. The automatic opening function of the overflow valve allows for real-time adjustment of the water level in the filling chamber 3021 without manual intervention, improving the system's automation and response speed. Through the coordinated action of the overflow valve and the drain valve, overloading of the support bag 3 is effectively prevented, ensuring it will not fail due to excessive water pressure under any circumstances. The overflow valve and drain valve allow the support bag 3 to adjust the water level according to actual needs, adapting to different flood control requirements. During non-flood seasons, the water in the bag can be drained through the drain valve, allowing the bag to be folded and stored, saving space and resources. The overflow valve and drain valve simplify the maintenance of the flood control system, allowing operators to easily inspect and clean the valves. During flood season, timely adjustment of the water level in the filling chamber 3021 improves the stability of the flood wall, thereby increasing flood control efficiency. The dual valve configuration provides double protection for the flood control system, enhancing the overall system reliability.

[0035] In some embodiments, the flood control device 100 further includes a return spring 6. The first end 201 of the return spring 6 is connected to the base 1, and the second end 202 of the return spring 6 is connected to the first water baffle 2. The return spring 6 is used to drive the first water baffle 2 to rotate relative to the base 1 after the support bag 3 is vented, so as to fold the first water baffle 2.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, the return spring 6 is an elastic device used to help the first baffle plate 2 return to its initial position after the support bag 3 is vented. One end of the return spring 6 is fixed to the base 1, and the other end is connected to the first baffle plate 2.

[0037] When the gas in the support bag 3 is expelled and the bag contracts, the return spring 6 will be stretched or compressed. Once the air pressure inside the bag drops to a certain level, the return spring 6 will release its elastic potential energy, causing the first baffle plate 2 to rotate relative to the base 1, folding it up for easy storage and relocation.

[0038] The addition of the return spring 6 allows the first flood barrier 2 to fold automatically without manual intervention, improving the automation level of the flood control device 100. After flood control, the return spring 6 quickly helps the flood barrier return to its original position, reducing manual operation time and labor, and improving the efficiency of flood control operations. The return spring uses the elastic potential energy to reset the flood barrier, eliminating the need for additional energy input and saving energy consumption. The return spring 6 has a relatively simple structure, is easy to inspect and maintain, and reduces the system's maintenance difficulty and cost. When the flood barrier is not in use, the return spring 6 helps the flood barrier fold, allowing the entire device to be stored more compactly, reducing space requirements.

[0039] In some embodiments, the flood control and flood season control device 100 further includes a water injection assembly 7, which includes a rotating shaft 701, a water wheel 702, a cam 703, an elastic water bladder 704, and a water intake pipe 705. The rotating shaft 701 is rotatably mounted on the base 1 in a vertical direction. The water wheel 702 is mounted on the rotating shaft 701, the cam 703 is mounted on the rotating shaft 701, the elastic water bladder 704 is mounted on the base 1, one end of the water intake pipe 705 is connected to the elastic water bladder 704, and the water injection pipe 5 is connected to the elastic water bladder 704. The water wheel 702 is used to rotate during flood driving to drive the cam 703 to rotate. The rotation of the cam 703 is used to intermittently squeeze the elastic water bladder 704, so that the water intake pipe 705 draws water into the elastic water bladder 704 and delivers the water to the filling chamber 3021 through the water injection pipe 5.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, a rotating shaft 701 is rotatably mounted vertically on the base 1, serving as the rotation shaft 701 for the waterwheel 702 and the cam 703. The waterwheel 702 is mounted on the rotating shaft 701 and rotates due to the impact of the water flow when the floodwaters flow. The cam 703 is also mounted on the rotating shaft 701 and is concentric with the waterwheel 702. When the waterwheel 702 rotates, the cam 703 also rotates accordingly. An elastic water bladder 704 is mounted on the base 1 and is used to store water drawn in by the mechanism of the waterwheel 702 and the cam 703. One end of the suction pipe 705 is connected to the elastic water bladder 704, and the other end is exposed to the floodwaters for drawing in water. The water injection pipe 5 is connected to the elastic water bladder 704 and is used to transport the water in the elastic water bladder 704 to the water filling cavity 3021 of the support bag 3.

[0041] The floodwaters drive the water turbine 702 to rotate, and the movement of the water turbine 702 drives the cam 703 to rotate via the shaft 701. The rotation of the cam 703 intermittently compresses the elastic water bladder 704, creating a negative pressure, which draws water into the elastic water bladder 704 through the suction pipe 705. Subsequently, the water is transported to the filling chamber 3021 through the water injection pipe 5, causing the support bag 3 to fill with water and expand to resist the flood.

[0042] This setup cleverly utilizes the energy of floodwaters for automatic water filling, eliminating the need for an external power source and reducing energy consumption and operating costs. The automated water filling process is achieved through the mechanism of the water turbine 702 and cam 703, improving the response speed and operational efficiency of the flood control device 100. This setup automatically adjusts the water filling rate according to the size and flow velocity of the flood, enhancing the device's adaptability. During non-flood seasons, the device can automatically empty, saving water resources and reducing maintenance and storage space requirements. Because the water filling process is automatic, the need for manual operation is reduced, thereby lowering operational risks. The water injection component 7 is typically simple to install, facilitating maintenance and replacement.

[0043] In some embodiments, the water suction pipe 705 is provided with a first one-way valve, the opening 204 of the first one-way valve facing the elastic water bladder 704, and the water injection pipe 5 is provided with a second one-way valve, the opening 204 of the second one-way valve facing away from the elastic water bladder 704.

[0044] The first one-way valve is installed on the suction pipe 705, with its opening 204 facing the elastic water bladder 704. This one-way valve allows water to flow from the suction pipe 705 into the elastic water bladder 704 while preventing water from flowing out of the elastic water bladder 704. The second one-way valve is installed on the injection pipe 5, with its opening 204 facing away from the elastic water bladder 704. This one-way valve allows water to flow from the elastic water bladder 704 through the injection pipe 5 to the filling chamber 3021, while preventing water from flowing back from the filling chamber 3021 into the elastic water bladder 704.

[0045] The one-way valve ensures that water flows in only one direction: from the suction pipe 705 into the elastic water bladder 704, and then from the elastic water bladder 704 through the injection pipe 5 to the filling chamber 3021, preventing backflow. Because the water flow direction is controlled, the filling process is highly efficient, allowing the elastic water bladder 704 to quickly fill with water and effectively deliver the water to the filling chamber 3021 of the supporting bladder 3. The one-way valve prevents backflow, avoiding water loss caused by backflow and ensuring the stability and reliability of the filling system. The one-way valve also simplifies the filling process, reduces operator intervention, and increases the degree of automation.

[0046] In some embodiments, the flood control device 100 further includes a second baffle plate 8. The first baffle plate 2 has a receiving cavity 203 and an opening 204. The opening 204 is located on the end face of the second end 202 of the first baffle plate 2. The second baffle plate 8 is slidably disposed in the receiving cavity 203 so that the second baffle plate 8 extends out of the receiving cavity 203 relative to the first baffle plate 2 through the opening 204.

[0047] The first flood barrier 2 has a receiving cavity 203 and an opening 204. The receiving cavity 203 is used to receive the second flood barrier 8, while the opening 204 is located on the end face of the second end 202 of the first flood barrier 2, allowing the second flood barrier 8 to extend therefrom. The second flood barrier 8 is slidably disposed within the receiving cavity 203. When enhanced flood control is required, the second flood barrier 8 can extend out of the receiving cavity 203 relative to the first flood barrier 2 through the opening 204, forming a higher flood barrier.

[0048] The addition of the second water-retaining plate 8 increases the overall height of the flood wall, enhancing its flood resistance, especially in the face of floods exceeding standard levels. Through its sliding mechanism, the second water-retaining plate 8 can be retracted into the receiving cavity 203 when not needed, reducing land occupation and improving the flexibility of the flood control device 100. During non-flood seasons or when the flood risk is low, the second water-retaining plate 8 can be retracted, saving space and facilitating management and maintenance. The sliding mechanism of the second water-retaining plate 8 simplifies operation, allowing operators to easily control its extension and retraction. Depending on changes in flood level, operators can selectively use the first water-retaining plate 2 or both the first and second water-retaining plates 8 simultaneously, enhancing the device's adaptability. During floods, the rapid extension of the second water-retaining plate 8 can quickly increase the height of the flood wall, reducing the risk of flood disasters. The sliding mechanism of the second water-retaining plate 8 also facilitates inspection and maintenance.

[0049] In some embodiments, the first baffle plate 2 has a groove 205 on its water-facing surface, and the second baffle plate 8 has a slider 801 that slidably engages within the groove 205. The flood control and flood season control device 100 also includes a buoyancy airbag 9, which is connected to the slider 801 to drive the second baffle plate 8 to slide, adapting to the flood depth. A gas generator 4 is connected to the buoyancy airbag 9 to inflate it, and the buoyancy airbag 9 is equipped with a second safety valve.

[0050] The first baffle plate 2 has a groove 205 on its water-facing surface, while the second baffle plate 8 has a slider 801 that slidably engages within the groove 205. This arrangement allows the second baffle plate 8 to slide freely within the groove 205. A buoyancy airbag 9 is connected to the slider 801 and is used to drive the second baffle plate 8 to slide. As the flood depth increases, the buoyancy airbag 9 expands under buoyancy, pushing the slider 801 and the second baffle plate 8 upwards, thereby increasing the height of the flood control wall. A gas generator 4 is connected to the buoyancy airbag 9 and is used to inflate it. This allows for active adjustment of the buoyancy of the buoyancy airbag 9 when necessary to adapt to different flood depths. The buoyancy airbag 9 is equipped with a second safety valve, which automatically releases gas when the air pressure inside the buoyancy airbag 9 exceeds a preset value, preventing damage to the airbag due to overpressure.

[0051] The buoyancy airbag 9 and slider 801 mechanism enable the flood wall to automatically adjust its height according to changes in flood depth, improving its adaptability and effectiveness. By adapting to flood depth, the flood wall can more effectively block floods and reduce their impact on the surrounding environment. The automatic inflation and deflation of the buoyancy airbag 9 reduces the need for manual intervention and increases the degree of automation in operation. The second safety valve prevents the buoyancy airbag 9 from being damaged by overpressure, ensuring system safety. The combination of the buoyancy airbag 9 and slider 801 mechanism improves the reliability of the flood wall, enabling it to operate stably under different flood conditions. During the non-flood season, the buoyancy airbag 9 can be deflated, and the slider 801 and the second baffle 8 can be retracted, reducing the occupation of land resources. The design of the buoyancy airbag 9 and slider 801 mechanism makes inspection and maintenance easier.

[0052] In some embodiments, a sealing ring is fitted on the second baffle plate 8, and the outer edge of the sealing ring abuts against the inner wall of the receiving cavity 203.

[0053] A sealing ring is fitted onto the second baffle plate 8. The outer edge of the sealing ring is in close contact with the inner wall of the receiving cavity 203, forming a sealed interface. When the second baffle plate 8 slides within the receiving cavity 203, the contact surface between the outer edge of the sealing ring and the inner wall of the receiving cavity 203 remains sealed, preventing water from leaking out from the gaps.

[0054] The sealing ring effectively prevents water leakage from the gap between the first baffle plate 2 and the second baffle plate 8, improving the flood control performance of the flood wall. The tight contact between the sealing ring and the inner wall of the receiving cavity 203 ensures a good seal, maintaining its effectiveness even under high flood pressure. The sealing ring minimizes leakage, thus reducing the impact on the flood wall's performance. It also reduces water erosion of the contact surface between the first baffle plate 2 and the second baffle plate 8, extending the flood wall's service life. The sealing ring is typically simple to install and maintain. It can be replaced or adjusted as needed to adapt to different operating environments and flood control requirements.
