Description

Technical Field

[0001] The utility model relates to the technical field of floating inflatable devices on water, in particular to a floating inflatable device for amphibious vehicles and ships. Background Art

[0002] Amphibious vehicles and ships are designed with a certain amount of buoyancy reserve, but during use at sea, the vehicle body may be damaged, the wind and waves are too strong, or the operation is wrong, which may cause water to enter the vehicle or ship. If rescue is not timely, it may cause casualties and vehicle or ship sinking accidents. In response to this rescue demand, there is an additional emergency flotation device in China. The device is composed of multiple groups of flotation components. A single group of flotation components mainly consists of air bags, gas cylinders, quick-release valves, pull ropes, fixed hanging plates, etc. In an emergency, it can be temporarily hung and started to deploy to increase the buoyancy of the vehicle or ship.

[0003] The device is not fixed, and pre-installation will affect the navigation of the vehicle and ship on the water. When in use, the operator needs to come out of the cabin and temporarily install it before it can be deployed. In an emergency on the water, the operator is under great psychological pressure. In addition, the vehicle and ship sway due to waves, and the installation operation is difficult. It requires multiple people to operate at the same time or one person to operate multiple times, which may delay the rescue opportunity. In addition, each set of buoyancy aid components is activated by pulling their own pull ropes. The synchronization of the startup operation is difficult to ensure, which may cause the vehicle and ship to tilt too much and cause rollover.

[0004] For example, Chinese Patent Publication (Announcement) No.: CN220228730U, Patent Title: Emergency Buoyancy-Assisted Rapid Inflatable Device for Amphibious Craft, discloses that “

[0034] The working process of the utility model based on the above-mentioned emergency buoyancy-assisted rapid inflatable device for amphibious craft is as follows: first, the rope outside the storage shell 11 is cut off, and the ejection member inside the storage shell 11 ejects the storage shell 11, and then the start button on the amphibious craft driving platform is pressed. At this time, the electric explosion valve 5 is energized to open the high-pressure gas cylinder 3, and the high-pressure gas in the high-pressure gas cylinder 3 enters the inlet of the ejector 8 through the pressure reducing valve 7 as a power source, and at the same time, the outside air is sucked into the ejector 8 for uniform mixing, and then the mixed gas is quickly filled into the float 12 through the outlet of the ejector 8, the outlet end of the pipeline 6, and the inflation check valve 9 in turn. When the pressure in the float 12 exceeds the design value, the pressure is released to the outside through the pressure relief valve 10 to prevent the float 12 from being damaged by excessive pressure. The working principle of this embodiment is shown in FIG. Figure 5 ” working process.

[0005] However, in actual application, it has the defect of not responding quickly enough because it needs to "cut off the rope outside the storage shell 11 first", and there is room for improvement. Summary of the invention

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example 1

[0027] Please refer to Figure 1 -7, the present embodiment provides an amphibious vehicle and ship flotation aid device, including a pneumatic control cylinder 1 for starting the gas source device, the pneumatic control cylinder 1 is divided into four parts by a pneumatic control pipeline 2, each pneumatic control pipeline 2 controls a set of pneumatic cylinder head valves 3, each set of pneumatic cylinder head valves 3 controls a gas cylinder 4, and the inflation pipeline 5 coming out of each gas cylinder 4 connects two adjacent air bags 6. Furthermore, the gas cylinder selected for the gas cylinder 4 preferably adopts a carbon fiber composite gas cylinder with light weight, high strength and good safety. The compressed gas filled in the gas cylinder 4 preferably adopts liquid carbon dioxide added with an appropriate amount of alcohol and nitrogen, which is not easy to leak, freezes and greatly saves the volume of the gas cylinder. Furthermore, the gas filled in the gas cylinder 4 can also be air, hydrogen, nitrogen, carbon dioxide or a mixed gas. In this embodiment, the two gas cylinders 4 are all installed in a gas cylinder box 22.

[0028] The airbag 6 is arranged in the airbag storage box 7, and the airbag storage box 7 is preferably arranged symmetrically. Figure 1 In this embodiment, an amphibious vehicle and ship buoyancy aid device is provided, wherein the number of the airbag storage boxes 7 is 8 groups, which are arranged symmetrically on the left and right. The airbag 6 is made of a material with certain sealing properties, such as polyurethane tape, Kevlar tape, and is cylindrical or spherical in shape when inflated, and folded in an uninflated state, and is installed in the airbag storage box 7. Furthermore, a pressure relief valve 21 is provided on the airbag 6 to maintain the balance of the internal air pressure. Furthermore, the airbag 6 can be composed of one or more airbag chambers connected together, and a single airbag chamber can function independently without being affected by other airbag chambers.

[0029] In the embodiments of the present utility model application, please refer to Figure 3 The airbag storage box 7 is a flat box, and is provided with an airbag storage box 8. One side of the airbag storage box 8 is rotatably connected to one side of the airbag storage box cover 10 through a hinge (9), and the other side of the airbag storage box cover 10 is connected to the other side of the airbag storage box 8 through a lock (11). The airbag storage box 7 has a certain sealing performance, and the box itself can also provide a certain buoyancy for the amphibious vehicle and ship. The box sealing can also reduce the maintenance workload of the airbag 6 and increase the service life of the airbag 6.

[0030] In the embodiments of the present utility model application, please refer to Figure 2 and Figure 6A guide plate 12 is provided on one side of the airbag storage box 7, and each two airbag storage boxes 7 are connected by a water baffle 13. A guide plate 12 is provided on one side (the front and rear sides) of the airbag storage box 7, and the gaps between the airbag storage boxes 7 are filled with water baffles 13, which can reduce the forward resistance of the vehicle and ship and increase the aesthetics.

[0031] The surface of the airbag storage box 7 is flush with the surface of the vehicle skirt, without changing the outer dimensions of the vehicle, thereby achieving fixed installation of the buoyancy aid component and not affecting the navigation and transportation of the amphibious vehicle on water. Guide plates 12 and water baffles 13 are installed at the front and rear ends to make the exterior a streamlined structure to reduce the impact on the vehicle's navigation speed.

[0032] In the embodiments of the present utility model application, please refer to Figure 7 The gas cylinder 4 controls two sets of airbag storage boxes 7 that are symmetrically positioned on the left and right. This structure of the gas cylinder 4 controlling two sets of airbag storage boxes 7 that are symmetrically positioned on the left and right makes the left and right sides of the vehicle and vessel balanced, preventing the unbalanced unilateral situation caused by the different number of airbags 6 opened on both sides (or asymmetric positions) in an accident. The arrangement of the airbag storage boxes 7 is similar to Figure 1 The arrangement is different.

[0033] In the embodiments of the present utility model application, please refer to Figure 2 and Figure 6 The airbag 6 is provided with an airbag fixing webbing 14. The airbag fixing webbing 14 acts buoyancy on the vehicle and the boat to achieve a floating effect.

[0034] In the embodiments of the present utility model application, please refer to Figure 3 The bottom surface of the airbag storage box 8 is provided with a force-bearing base 15. The force-bearing base 15 is installed on both sides of the vehicle and vessel, and is arranged symmetrically with the longitudinal axis of the vehicle body as the center, to ensure that the overall buoyancy center position of the airbag 6 after deployment is close to the buoyancy center position of the amphibious vehicle and vessel, and prevent the vehicle and vessel from tilting. The top surface of the airbag storage box 8 is provided with a threaded column 16. The threaded column 16 is used to fix the airbag storage box 7 on both sides of the amphibious vehicle and vessel through the installation accessories.

[0035] In the embodiments of the present utility model application, please refer to Figure 5 The lock buckle 11 is divided into a male buckle 17 and a female buckle 18. The male buckle 17 is provided with a protrusion 19, and the female buckle 18 is provided with a groove 20. When the airbag 6 is inflated, it presses against the airbag storage box cover 10, and the protrusion 19 on the male buckle 17 pushes open the groove 20 on the female buckle 18, and the lock buckle 11 collapses due to the greater internal pressure. When the airbag 6 is out of gas, it is placed in the airbag storage box 7, and the lock buckle 11 can be closed again, achieving the effect of repeated use.

[0036] The number correspondence between the gas cylinders 4 and the airbags 6 can be "one to one", "one to many" or "many to one". In this embodiment, it is "one to two".

[0037] This embodiment provides an amphibious vehicle and vessel flotation device, please refer to Figure 4 When an amphibious vehicle or ship is in use in the water and the body of the vehicle is accidentally flooded, endangering the safety of personnel and equipment, the cabin occupants or passengers open the matching switch of the pneumatic control cylinder 1 within a few seconds to release gas with a certain pressure. The gas is transmitted to the pneumatic bottle head valve 3 of each gas cylinder 4 through the pneumatic control pipeline 2. Under the action of air pressure, each pneumatic bottle head valve 3 opens the seal of the gas cylinder 4 to release the compressed gas in the bottle. The compressed gas is transmitted to the folded airbag 6 through the inflation pipeline 5, and the airbag 6 is inflated to form a rated buoyancy, and the buoyancy is applied to the vehicle or ship body through the airbag fixing webbing 14 to achieve the effect of assisting floating. From the discovery of the danger and the opening of the control switch to the full deployment of the airbag 6, the response time is fast, which can win precious time for the rescue of amphibious vehicles and ships in distress on the water.

[0038] The beneficial effect of the utility model is that the pneumatic control cylinder 1 provides power to drive the pneumatic cylinder head valve 3 to open the high-pressure gas in the cylinder 4, and the gas is quickly filled into the airbag 6, and the airbag 6 is instantly deployed to increase a certain buoyancy for the vehicle and the ship. This new structure does not need to cut the rope outside the storage shell, and the response is fast.

[0039] Since the present embodiment provides an amphibious vehicle and vessel flotation aid device, the airbag 6 is installed in the airbag storage box 7 (which is a flat box), which can be fixedly installed on both sides of the amphibious vehicle and vessel. After installation, the outer dimensions of the vehicle and vessel are not changed, and the navigation, use and transportation of the vehicle and vessel on the water are not affected. Moreover, the airbag storage box 7 in this solution is a relatively sealed box, which can provide a certain buoyancy to the amphibious vehicle and vessel, and also avoids a large amount of maintenance work caused by the airbag 6 being directly soaked in seawater every time the vehicle and vessel go to sea (maintenance work such as disassembly, deployment, fresh water washing, drying, folding, and installation of the airbag 6). In addition, this solution can adopt centralized control methods such as pneumatic, manual, wired electric control, and wireless remote control, and can be started in the cabin, ensuring the synchronization of startup and the timeliness of rescue.
