Abstract
Claims
1. A retractable inflatable water-blocking device with a linkage support structure, comprising: an inflation unit for providing water-blocking effect; and a support unit disposed on one side of the inflation unit, the support unit including a linkage frame module having a plurality of cross links, the cross links being pivotally connected to each other and movably coupled to the inflation unit; wherein... When the linkage frame module is in an unfolded state, the inflation unit is simultaneously expanded by the cross linkages, and the inflation unit, after being inflated, is used to abut against an external boundary.
2. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, The support unit includes a locking and fixing module with a limiting locking fastener that engages with one end of the cross links when they reach a maximum extended position, thereby restricting the degrees of freedom of the linkage frame module.
3. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, The inflation unit includes an inflation control module with a check valve that is airtightly connected to the interior of one of the inflation units.
4. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, The inflation unit includes an air-sealing module integrally formed on the outer periphery of the inflation unit.
5. The retractable inflatable water-blocking device with a linkage support structure as described in claim 4, wherein, The air-sealing module has a bottom edge seal and two side edge seals. The bottom edge seal is located at the bottommost side of the air-sealing module and is used to abut against a ground surface. The two side edge seals are located at the two ends of the air-sealing module and are used to abut against a wall surface.
6. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, The linkage frame module has a pivot member that is pivotally connected to the geometric center point where the intersecting links intersect, so that the intersecting links form a scissor-like folding structure.
7. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, The inflatable unit is made of one of the following: high-strength polyvinyl chloride, thermoplastic polyurethane rubber, or reinforced fiber composite mesh fabric.
8. The retractable inflatable water barrier device with a linkage support structure as described in claim 1, wherein, These cross links are made of one of lightweight aluminum alloys, stainless steel, or carbon fiber composite materials.
9. The retractable inflatable water-blocking device with a linkage support structure as described in claim 1, wherein, When the linkage frame module is in a retracted state, the cross links are synchronously retracted towards a central axis, and the inflation unit is in a folded and flattened state with the gas vented.
10. The retractable inflatable water-blocking device with a linkage support structure as described in claim 3, wherein, The check valve has a quick-connect structure for tool-free, quick, and airtight connection to an external air source.
