Description

Technical Field

[0001] The utility model relates to the technical field of amphibious armor emergency buoyancy assistance, and particularly relates to an emergency buoyancy assistance device for amphibious armor equipment. Background Art

[0002] Amphibious armor equipment refers to the general term for amphibious combat vehicles equipped with armored hulls that can travel on water and land. Amphibious armored vehicles are one of the main equipment of the Marine Corps, with seawater corrosion resistance and certain wave resistance performance, different from amphibious vehicles used in rivers. What structures does the emergency buoyancy assistance device include?

[0003] In the prior art, an emergency buoyancy assistance device is often used in amphibious armor equipment to provide buoyancy for the equipment. When the amphibious armor equipment is damaged and flooded at sea, the user installs the emergency buoyancy assistance device on the amphibious armor equipment, then injects gas into the expansion bag of the emergency buoyancy assistance device, and then the expansion bag inflates to provide buoyancy for the amphibious armor equipment.

[0004] However, when the emergency buoyancy assistance device is in use, it needs to be installed on the amphibious armor equipment by the user. The installation time causes the emergency buoyancy assistance device to not be able to operate in time, thereby increasing the amount of water entering the amphibious armor equipment. Moreover, when installing at sea, the sea waves increase the difficulty of installation for the operator. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an emergency buoyancy assistance device for amphibious armor equipment, so as to solve the technical problems in the prior art that when the emergency buoyancy assistance device is in use, it needs to be installed on the amphibious armor equipment by the user. The installation time causes the emergency buoyancy assistance device to not be able to operate in time, thereby increasing the amount of water entering the amphibious armor equipment. Moreover, when installing at sea, the sea waves increase the difficulty of installation for the operator.

[0006] The technical problems to be solved by the utility model can be realized through the following technical solutions:

[0007] An emergency buoyancy assistance device for amphibious armor equipment, comprising:

[0008] A bearing shell, wherein a plurality of fixing components are fixedly connected to the side end of the bearing shell along the length direction, and a plurality of partition plates are fixedly connected to the inner wall of the bearing shell at equal intervals along the length direction;

[0009] An expansion bag, wherein a plurality of groups of expansion bags are provided and are arranged in an alternating manner with the partition plates. The expansion bag is fixedly connected to the inner wall of the bearing shell and is cooperatively connected with the partition plates;

[0011] As a further solution of the utility model: A number of connecting holes are equidistantly arranged along the length direction at the side end of the bearing shell. One end of the bearing shell close to the fixing component is fixedly connected with a flow dividing box. A connecting pipe is arranged between the flow dividing box and the expansion bag, and a guide pipe is arranged between the flow dividing box and the air pump. The width of the flow dividing box is smaller than that of the fixing component. Both ends of the connecting pipe are fixedly connected with the flow dividing box and the expansion bag respectively, and the connecting pipe is in abutting connection with the inner wall of the connecting hole. Both ends of the guide pipe are fixedly connected with the flow dividing box and the air pump respectively.

[0012] As a further solution of the utility model: A number of air outlet holes are equidistantly arranged along the length direction at one end of the flow dividing box close to the expansion bag. An air inlet hole is arranged at the side end of the expansion bag. Both ends of the connecting pipe are communicated with the air outlet hole and the air inlet hole respectively.

[0013] As a further solution of the utility model: The fixing component includes a connecting plate and a fixing plate. The connecting plate is fixedly connected with the side end of the bearing shell, and the fixing plate is fixedly connected with the side end of the connecting plate. A fixing hole is penetrated through the top of the fixing plate.

[0014] As a further solution of the utility model: Slide plates are fixedly connected to both ends of the expansion bag respectively.

[0015] As a further solution of the utility model: Limiting plates in the shape of semi-cylinders are fixedly connected to the upper and lower ends of the slide plates respectively. The limiting plates are clamped in the slide grooves and are slidably connected with the slide grooves.

[0016] The beneficial effects of the utility model:

[0017] 1. Two sets of bearing shells can be provided. The bearing shells are installed on both sides of the amphibious armored equipment through the fixing component, ensuring that when the bearing shells are operating, the same buoyancy is provided on both sides of the amphibious armored equipment. It should be noted that when the amphibious armored equipment runs in the sea, the bearing shells are installed on the amphibious armored equipment in advance, avoiding the need for operators to install them when the amphibious armored equipment is damaged and flooded, saving emergency time and improving work efficiency.

[0018] 2. The air pump provides a power source for the inflation and expansion of the expansion bag.

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 - 6 shown, an emergency buoyancy assistance device for an amphibious armored equipment includes: a bearing shell 1, an expansion bag 5 and an air pump 7.

[0029] A plurality of fixing components are fixedly connected to the side end of the bearing shell 1 along the length direction. A plurality of partition boards 6 are fixedly connected to the inner wall of the bearing shell 1 at equal intervals along the length direction. Two groups of bearing shells 1 can be provided. The bearing shell 1 is installed on both sides of the amphibious armored equipment through the fixing components to ensure that when the bearing shell 1 operates, the same buoyancy is provided on both sides of the amphibious armored equipment. It should be noted that when the amphibious armored equipment operates in the sea, the bearing shell 1 is installed on the amphibious armored equipment in advance to avoid the need for operators to install it when the amphibious armored equipment is damaged and flooded, saving emergency time and improving work efficiency.

[0030] There are several groups of expansion bags 5, which are arranged alternately with the partition plates 6. The expansion bags 5 are fixedly connected to the inner wall of the bearing shell 1 and are cooperatively connected with the partition plates 6. When the expansion bags 5 are inflated by receiving gas, the buoyancy generated by the contact between the expansion bags 5 and seawater is transmitted to the amphibious armored equipment through the top support of the bearing shell 1. The two ends of the expansion bags 5 transmit the buoyancy to the bearing shell 1 through the partition plates 6, thus ensuring that the buoyancy of the expansion bags 5 can be fully transmitted to the amphibious armored equipment through the bearing shell 1. At the same time, the partition plates 6 separate several expansion bags 5 to prevent seawater from shaking several expansion bags 5 and ensure that the expansion bags 5 provide stable buoyancy for the amphibious armored equipment;

[0031] The air pump 7 is fixedly connected to the side end of the partition plate 6 and is cooperatively connected with the expansion bag 5. The air pump 7 provides a power source for inflating and expanding the expansion bag 5.

[0032] In some specific implementation schemes, a number of connection holes 16 are equidistantly arranged along the length direction at the side end of the bearing shell 1. One end of the bearing shell 1 close to the fixing component is fixedly connected with a flow dividing box 11. A connecting pipe 13 is arranged between the flow dividing box 11 and the expansion bag 5, and a guide pipe 10 is arranged between the flow dividing box 11 and the air pump 7. The width of the flow dividing box 11 is smaller than the width of the fixing component. The two ends of the connecting pipe 13 are respectively fixedly connected with the flow dividing box 11 and the expansion bag 5, and the connecting pipe 13 is in abutting connection with the inner wall of the connection hole 16. The two ends of the guide pipe 10 are respectively fixedly connected with the flow dividing box 11 and the air pump 7. The flow dividing box 11 is provided with a number of air outlet holes 14 equidistantly along the length direction at one end close to the expansion bag 5. An air inlet hole 15 is arranged at the side end of the expansion bag 5. The two ends of the connecting pipe 13 are respectively communicated with the air outlet hole 14 and the air inlet hole 15. When the amphibious armored equipment is damaged and flooded, the operator turns on the air pump 7. The air pump 7 operates to transmit the gas to the flow dividing box 11 through the guide pipe 10. The gas gathers in the flow dividing box 11 and then flows out from the air outlet holes 14 opened in the flow dividing box 11 respectively. The gas enters the expansion bag 5 through the connecting pipe 13 and the air inlet hole 15. The flow dividing box 11 has the effect of dividing the gas. Compared with the existing emergency buoyancy aid device that is inflated separately, the flow dividing box 11 can divide the gas to each expansion bag 5 to ensure that each expansion bag 5 is inflated simultaneously, thereby reducing the working time for the emergency buoyancy aid device to inflate and provide buoyancy for the amphibious armored equipment. Among them, the connecting pipe 13 can prevent seawater from entering the flow dividing box 11 and the expansion bag 5 from the connection hole 16, further strengthening the connection between the flow dividing box 11 and the expansion bag 5.

[0033] In some specific embodiments, the fixing component includes: a connecting plate 2 and a fixing plate 3. The connecting plate 2 is fixedly connected to the side end of the bearing shell 1, and the fixing plate 3 is fixedly connected to the side end of the connecting plate 2. A fixing hole 12 is formed through the top of the fixing plate 3. When the bearing shell 1 is installed through the fixing component, the fixing component avoids the phenomenon that the shunt box 11 does not match the amphibious armored equipment. The fixing plate 3 can be fixed on the amphibious armored equipment by bolts in the prior art, and the bolts can be connected to the amphibious armored equipment by passing through the fixing hole 12.

[0034] In some specific embodiments, sliding plates 8 are respectively fixedly connected to both ends of the expansion bag 5. A diversion bag 4 in the shape of a hemisphere is fixedly connected to one end of the expansion bag 5 away from the bearing shell 1. The expansion bag 5 is in communication with the diversion bag 4. Chute grooves 9 are respectively formed at both ends of the partition plate 6. The sliding plates 8 are slidably connected to the chute grooves 9. Semi-cylindrical limiting plates 17 are respectively fixedly connected to the upper and lower ends of the sliding plates 8. The limiting plates 17 are clamped in the chute grooves 9 and are slidably connected to the chute grooves 9. In order to ensure that the buoyancy of the expansion bag 5 is transmitted through the partition plate 6, when the expansion bag 5 is inflated and expanded, the expansion bag 5 drives the sliding plates 8 to slide along the chute grooves 9. The limiting effect of the limiting plates 17 and the chute grooves 9 ensures that the sliding plates 8 will not fall off horizontally from the chute grooves 9. The expansion bag 5 transmits the buoyancy to the partition plate 6 through the abutment of the sliding plates 8 and the chute grooves 9. In order to prevent the sea water from causing large shaking to the expansion bag 5, the diversion bag 4 fixed to the side end of the expansion bag 5 will also be inflated and expanded. The diversion bag 4 has a diversion effect on the sea water, reducing the phenomenon that the sea water directly hits the expansion bag 5, and reducing the shaking effect generated by the contact between the expansion bag 5 and the sea water.

[0035] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
