Description

Technical Field

[0001] This invention relates to the field of flood control devices, and more specifically to a flood control enclosure with automatic adjustment of flood level. Background Technology

[0002] Flood control barriers are flood-resistant and water-blocking devices used to temporarily block rapidly rising floodwaters, preventing buildings or farmland from being submerged. They are suitable for areas prone to heavy rainfall and typhoons, playing a vital role in protecting people's lives and property. Flood control barriers are typically constructed as panels; however, the structure of these panels requires a high degree of flatness on the bottom surface, making them unsuitable for various placement surfaces. Furthermore, the panels occupy a significant amount of space, making them very space-consuming to store. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a flood control barrier with automatic adjustment of flood level, which can adapt to various shapes of placement surface, has a wide range of applicable scenarios and small storage space.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A flood control barrier with automatic flood level adjustment includes one or more barrier units, wherein the barrier units are detachably connected, and each barrier unit includes...

[0006] The first enclosure portion is equipped with a counterweight to ensure it fits snugly against the placement surface.

[0007] The second enclosure portion has one side connected to and bendable from the first enclosure portion.

[0008] Several telescopic connecting parts are provided, one end of which is fixedly connected to a first enclosure part, and the other end of which is fixedly connected to a second enclosure part, thereby forming several enclosure spaces between the first enclosure part and the second enclosure part.

[0009] A support member is provided to support the second enclosure portion so that a flow gap is formed between the first enclosure portion and the second enclosure portion for liquid to flow into the enclosure space.

[0010] In this invention, preferably, the support member includes a transverse airbag, which is disposed at the end of the second enclosure portion away from the first enclosure portion and is fixedly connected to the side of the second enclosure portion near the first enclosure portion.

[0011] A storage component is provided between the first enclosure and the second enclosure. The storage component is connected to the transverse airbag. The storage component is provided with a flow pipe for unidirectional liquid inflow. The transverse airbag is provided with a one-way valve for unidirectional gas outflow so that liquid can enter through the flow pipe and be stored in the storage component.

[0012] In this invention, preferably, the flow pipe includes an inlet and an outlet, and the flow pipe is provided with a main channel and several branch channels. Each branch channel includes a direct flow section and a swirling section. The direct flow section and the swirling section are respectively connected to the main channel. The direct flow section is formed on the side of the swirling section near the outlet. The swirling section convexes towards the inlet. The flow directions at both ends of the branch channel are opposite and inclined to the corresponding main channel.

[0013] In this invention, preferably, a plurality of bends are alternately formed on the main channel, the bends corresponding one-to-one with the branch channels, the branch channels are alternately formed on both sides of the main channel, and the flow direction of the direct flow section is the same as the flow direction of the corresponding adjacent bend.

[0014] In this invention, preferably, the storage component includes a vertically arranged storage cloth, which is fixedly connected to the first enclosure and the second enclosure and forms a liquid storage cavity. The storage cloth can extend or contract with the movement of the second enclosure to change the volume of the liquid storage cavity. The cross-section of the liquid storage cavity is a trapezoidal cross-section, and the long base of the trapezoidal cross-section corresponds to the second enclosure.

[0015] In this invention, preferably, the storage cloth is inclined and angled away from the second enclosure so that the side lengths of the trapezoidal cross section decrease sequentially from bottom to top.

[0016] In this invention, preferably, the flow pipe is disposed on the first enclosure portion, and the inlet of the flow pipe faces the opening side of the enclosure space. A guide cloth is disposed between the first enclosure portion and the storage cloth, and the guide cloth is used to guide the liquid to the flow pipe.

[0017] In this invention, preferably, the guide cloth is provided with a plurality of receiving protrusions, the receiving protrusions protruding toward the side of the guide cloth that is far apart from each other and forming an impurity receiving cavity.

[0018] In this invention, preferably, both ends of the transverse airbag are provided with sealing ports, and each sealing port is provided with two magnets that can attract each other. The magnets located at both ends of the transverse airbag are arranged with opposite polarities so that multiple flood control units can be attracted in sequence.

[0019] In this invention, preferably, the one-way valve includes a valve body that extends through the second enclosure and is exposed on the side away from the transverse airbag, and the valve body is provided with a valve plate and a valve diaphragm.

[0020] The beneficial effects of this invention are:

[0021] 1. The present invention, through the setting of multiple enclosure units, facilitates splicing and combination according to actual use scenarios. Furthermore, through the combination of the flexible first enclosure part and the counterweight, the flood control enclosure designed in this application can be applied to various scenarios without being affected by the placement surface. Moreover, after the water flows into the enclosure space, the pressure of the accumulated water itself is used to further fix the enclosure unit, resulting in good enclosure and fixing effects.

[0022] 2. The present invention, through the setting of the support component, allows for a flow gap between the second enclosure and the first enclosure in a natural state. In flood control applications, water can enter the enclosure space without manual lifting of the second enclosure, which is convenient to use and reduces manual input. Combined with the setting of the horizontal airbag and storage component, the edge of the second enclosure floats on the water surface, making the flood control enclosure more reliable.

[0023] 3. By utilizing the storage components and flow pipes, the storage components can store some of the accumulated water, thereby maintaining the height of the second enclosure at a higher position. This prevents the water level from rising again after it drops, thus avoiding the overflow of the second enclosure. At the same time, the storage components have a certain compensating effect on the changes in air pressure inside the transverse airbags, resulting in a better water-blocking effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please also see Figures 1 to 4This embodiment provides a flood control barrier with automatic flood level adjustment, comprising one or more barrier units that are detachably connected. Each barrier unit includes a first barrier section 1, a second barrier section 2, and several telescopic connecting sections 3. The first barrier section 1 is equipped with a counterweight 6 to ensure it fits against the placement surface. One side of the second barrier section 2 is connected to the first barrier section 1 and is bendable. One end of each telescopic connecting section 3 is fixedly connected to the first barrier section 1, and the other end is fixedly connected to the second barrier section 2, thus forming several barrier spaces between the first barrier section 1 and the second barrier section 2. Specifically, in this embodiment, the first barrier section 1 and the second barrier section 2 can be configured as a single piece of waterproof fabric, or they can be fixed together as two parts, facilitating folding and storage of each barrier unit after use. The first enclosure 1 and the second enclosure 2 are equipped with Velcro straps, allowing adjacent enclosure units to be detachably connected via the Velcro straps, achieving a good connection effect, preventing water leakage, and facilitating splicing and combination according to actual usage scenarios. Furthermore, the combination of the flexible first enclosure 1 and the counterweight 6 allows the flood control enclosure designed in this application to be applicable to various scenarios regardless of the placement surface. Moreover, after water enters the enclosure space, the pressure of the accumulated water further secures the enclosure units, resulting in good enclosure and fixation effects.

[0034] The enclosure unit also includes a support member, which provides support for the second enclosure portion 2 to create a flow gap between the first enclosure portion 1 and the second enclosure portion 2 for liquid to flow into the enclosure space. In this embodiment, the support member includes a transverse airbag 4, which is disposed at the end of the second enclosure portion 2 away from the first enclosure portion 1 and is fixedly connected to the side of the second enclosure portion 2 near the first enclosure portion 1. The transverse airbag 4 provides initial buoyancy to the second enclosure portion 2, enabling it to float on the surface of the accumulated water. A storage member 5 is disposed between the first enclosure portion 1 and the second enclosure portion 2. The storage member 5 is connected to the transverse airbag 4, meaning that the gas pressure inside the storage member 5 and the transverse airbag 4 is the same. The storage member 5 is provided with a flow pipe 51 for unidirectional liquid inflow, and the transverse airbag 4 is formed with a one-way valve 41 for unidirectional gas outflow, allowing liquid to enter through the flow pipe 51 and be stored in the storage member 5. The cooperation between the transverse airbag 4 and the storage unit 5 has two specific functions. First, during the rising water level, the water will exert pressure on the storage unit 5, and the pressure on the bottom of the storage unit 5 will increase as the water level rises. As a result, the water can enter the storage unit 5 by means of the pressure difference, and the air inside the storage unit 5 can be discharged through the one-way valve 41 to ensure the realization of the water storage function. Second, during the falling water level, the pressure of the water on the outer wall of the storage unit 5 decreases as the water level drops, and the pressure inside the storage unit 5 tends to decrease, preventing the water inside the storage unit 5 from flowing out. This ensures that the second enclosure part 2 can maintain a certain height and uses the water itself to support the enclosure unit.

[0035] The one-way valve 41 includes a valve body that passes through the second enclosure 2 and is exposed on the side away from the transverse airbag 4. The valve body is provided with a valve plate and a valve diaphragm to ensure one-way airflow. Specifically, in this embodiment, the one-way valve 41 is designed to be detachable. The transverse airbag 4 has a connector for installing the one-way valve 41 so that the enclosure unit can be folded and stored as a whole.

[0036] In this implementation plan, refer to Figure 2 As shown, the flow pipe 51 includes an inlet 511 and an outlet 512. A main flow channel 513 and several branch channels are provided within the flow pipe 51. Each branch channel includes a direct flow section 515 and a swirling flow section 514, which are connected to the main flow channel 513. The direct flow section 515 is formed on the side of the swirling flow section 514 near the outlet 512. The swirling flow section 514 protrudes towards the inlet 511. The flow directions at both ends of the branch channels are opposite and inclined to the corresponding main flow channel 513. Several bends are alternately formed on the main flow channel 513, each bend corresponding to a branch channel. The branch channels are alternately formed on both sides of the main flow channel 513, and the flow direction of the direct flow section 515 is the same as the flow direction of the corresponding adjacent bend. The working principle of the flow pipe 51 is that by setting up the main flow channel 513 and the branch flow channel, the resistance of the liquid is small when the liquid flows in the positive direction, that is, from the inlet 511 to the outlet 512, which facilitates the positive flow of the liquid, while providing a large flow resistance to the reverse flow and blocking it.

[0037] The storage component 5 includes a vertically arranged storage cloth, which is fixedly connected to the first enclosure 1 and the second enclosure 2 to form a liquid storage cavity. The storage cloth can extend or contract with the movement of the second enclosure 2 to change the volume of the liquid storage cavity. The cross-section of the liquid storage cavity is trapezoidal, and the long base of the trapezoidal cross-section corresponds to the second enclosure 2. The storage cloth is inclined and angled away from the second enclosure 2 so that the lengths of the sides of the trapezoidal cross-section decrease from bottom to top. The shape of the storage cavity is designed to take into account deformation, that is, the deformation of the outer wall of the storage component 5 before and after receiving water pressure needs to be small, so as to ensure that the second enclosure 2 can still maintain a higher support position than when the water level is high after the water level drops to a certain height, which can prevent water from overflowing the second enclosure 2 due to the water level rising again after dropping. At the same time, the arrangement of the storage component 5 has a certain compensating effect on the air pressure change inside the transverse airbag 4, making the water blocking effect better.

[0038] Please refer to Figure 3 Both ends of the transverse airbag 4 are provided with sealing ports, and each sealing port is provided with two magnets 42 that can attract each other. The magnets 42 located at both ends of the transverse airbag 4 are arranged with opposite polarities so that multiple flood control units can be attracted in sequence. This arrangement facilitates the inflation and deflation of the transverse airbag 4 and is convenient to use.

[0039] Please refer to Figure 4 A flow pipe 51 is disposed on the first enclosure part 1, and the inlet 511 of the flow pipe 51 faces the opening side of the enclosure space. A guide cloth 52 is disposed between the first enclosure part 1 and the storage cloth, and the guide cloth 52 is used to guide the liquid to the flow pipe 51. A plurality of receiving protrusions 521 are provided on the guide cloth 52, and the receiving protrusions 521 protrude toward the side of the guide cloth 52 that is far away from each other and form an impurity receiving cavity.

[0040] Working principle:

[0041] The flood control enclosure involved in this application can be spliced ​​according to usage requirements. In use, a single enclosure unit is unfolded, and then the horizontal airbag 4 is inflated. Due to its shape, the entire enclosure unit can be shaken to allow air to enter the horizontal airbag 4 and the storage unit 5. Then, the horizontal airbag 4 is sealed using magnet 42. At this point, under the action of the storage unit 5 and the horizontal airbag 4, the second enclosure part 2 of a single enclosure unit can be supported to a certain height, facilitating the entry of accumulated water into the enclosure space. This process does not require manual lifting of the second enclosure part 2. Multiple enclosure units are then spliced ​​together, and counterweights 6 are stacked on top of the first enclosure part 1 to fix the position of the enclosure units. The rise in water level increases the pressure difference on both sides of the inlet 511 of the flow pipe 51, causing the accumulated water to enter the storage unit 5 through the main channel 513 and supporting the second enclosure part 2 to a certain height. When the water level drops, such as during low tide, the water level decreases, and the water inside the storage unit 5 is retained inside the storage unit 5, thus providing better support.

[0042] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
