Description

Technical Field

[0001] The invention relates to a marine airbag, in particular to a high-strength marine airbag applied in the field of marine airbags. Background Art

[0002] Ship launching airbags are a type of equipment specially designed for transferring ships from land to water. They provide a safe, economical and efficient method of launching ships. When using ship launching airbags, multiple airbags are first arranged in parallel on the slide at the bottom of the ship, and then an air pump is used to inflate the airbags to expand them and lift the hull.

[0003] When the airbag supports the hull, the internal air pressure distribution needs to be uniform. Uniform air pressure can ensure that the airbag can provide consistent support in all directions. If the air pressure distribution is uneven, it may cause insufficient support or excessive expansion of certain parts, making the support strength of the airbag lower.

[0004] Since the sizes of different hulls are different, and the widths of the hulls at different positions are also different, while the specifications of the airbags are roughly the same, it is very easy to cause uneven pressure on the airbags, which not only reduces the supporting strength of the airbags, but also easily causes the airbags to be damaged due to uneven pressure. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the airbag is very likely to be unevenly compressed when in use, which not only reduces the supporting strength of the airbag, but also easily causes the airbag to be damaged due to the uneven pressure.

[0006] In order to solve the above problems, the present invention provides a high-strength marine airbag, comprising a plurality of support airbags, wherein an air-expandable airbag is arranged between every two adjacent support airbags, and both ends of the air-expandable airbag are fixedly connected to both ends of the support airbag through a connecting column, a through tube is fixedly connected through the top end of the connecting column, and an airbag tube is fixedly connected through the bottom end of the connecting column, one end of the two through tubes located inside the air-expandable airbag is connected through an air switch valve, and one end of the two airbag tubes located inside the support airbag is connected through a transfer tube, and finally The left end of the left support airbag is fixedly connected to an air supply column, the right end of the rightmost support airbag is fixedly connected to a closing column, one end of the closing column is fixedly connected to an exhaust pipe, one end of the exhaust pipe is fixedly connected to an air release valve, the middle of the top and bottom ends of the air supply column are respectively penetrated and fixedly connected with an upper inflation tube and a lower inflation tube, one end of the upper inflation tube and the lower inflation tube are fixedly connected to an air connecting nozzle, the outer wall of the upper inflation tube and the outer wall of the lower inflation tube are respectively installed with an upper pressure gauge and a lower pressure gauge, a long connecting pipe is fixedly connected between one end of the lower inflation tube and one end of the leftmost airbag tube.

[0007] As a further improvement of the present application, the gas switch valve includes a valve body fixedly connected to one of the connecting columns, the two ends of the valve body are respectively fixedly connected to the inlet and outlet pipes, and one end of the two inlet and outlet pipes is respectively fixedly connected to one end of the two through pipes with a connecting pipe.

[0008] As a further improvement of the present application, a valve ring is fixedly connected to the middle of the valve body, a rotating shaft is rotatably connected to the middle of the valve ring, and an outer wall of the rotating shaft is fixedly connected to a closing fan matching the valve ring.

[0009] As a further improvement of the present application, one end of the rotating shaft extends to the outside of the valve body and is fixedly connected to a gear, and one end of the other connecting column is fixedly connected to a rack, and the rack is meshed with the gear. Through the above arrangement, when one of the support airbags is damaged, the remaining support airbags can still support the hull, further improving the supporting effect on the hull.

[0010] As another improvement of the present application, the connecting column consists of an inner column and an outer ring, the inner column is fixedly connected to the air expansion bag, the outer ring is fixedly connected to the support bag, the inner column and the outer ring are threadedly connected, and the air bag tube and the transfer tube are threadedly connected. Through the above arrangement, the present device can be applied to hulls of a wider range of specifications.

[0011] As another improvement supplement of the present application, a protective cover is provided between the multiple support airbags, and the protective cover is located on the outside of the air-expandable airbags. Through the above arrangement, the air-expandable airbags can be protected.

[0012] As another improved supplement of the present application, one end of the rightmost airbag tube is threadedly connected with a closing cap.

[0013] To summarize, before use, the interior of the support airbag is inflated through the upper inflation tube. When the support airbag is inflated, the inflation equipment is used to connect it to the air connecting nozzle on the lower inflation tube, and the interior of all the air expandable airbags is inflated through the lower inflation tube, the long connecting tube and the airbag tube. The length of the air expandable airbag is adjusted, and the length of the air expandable airbag can be obtained by observing the lower pressure gauge at the same time, until the total length of the support airbag and the air expandable airbag is equal to the width of the boat. Through the above arrangement, the total length of the support airbag and the air expandable airbag can be adjusted to be equal to the width of the hull. At this time, the support airbag can play a better supporting role on the hull when used, preventing the hull from being insufficiently supported or the support airbag from leaking out of the hull, so that the support airbags at different positions are evenly stressed, thereby improving the supporting strength of the support airbag.

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-7A high-strength marine airbag is shown, comprising a plurality of support airbags 1, an air-expandable airbag 2 is arranged between every two adjacent support airbags 1, both ends of the air-expandable airbag 2 are fixedly connected to both ends of the support airbag 1 through a connecting column 3, a through tube 4 is passed through and fixedly connected to the top end of the connecting column 3, an airbag tube 6 is passed through and fixedly connected to the bottom end of the connecting column 3, one end of the two through tubes 4 located inside the air-expandable airbag 2 is connected through an air switch valve 5, one end of the two airbag tubes 6 located inside the support airbag 1 is connected through a transfer tube 7, the left end of the leftmost support airbag 1 is fixedly connected to an air supply column 8, and the rightmost support airbag 1 The right end is fixedly connected with a closing column 9, one end of the closing column 9 is fixedly connected with an exhaust pipe 12, one end of the exhaust pipe 12 is fixedly connected with a deflation valve 1201, the middle part of the top and bottom ends of the air supply column 8 are respectively penetrated and fixedly connected with an upper inflation tube 10 and a lower inflation tube 11, one end of the upper inflation tube 10 and the lower inflation tube 11 are fixedly connected with an air connecting nozzle 13, the outer wall of the upper inflation tube 10 and the outer wall of the lower inflation tube 11 are respectively installed with an upper pressure gauge 1001 and a lower pressure gauge 1101, a long connecting tube 14 is fixedly connected between one end of the lower inflation tube 11 and one end of the leftmost airbag tube 6, and one end of the rightmost airbag tube 6 is threadedly connected with a closing cap 16.

[0026] Before use, use an inflation device to connect to the air connection nozzle 13 on the upper inflation tube 10, and inflate the interior of the support airbag 1 through the upper inflation tube 10. Since multiple support airbags 1 are connected through the tube 4 and the air switch valve 5, all the support airbags 1 can be filled. After the inflation of the support airbag 1 is completed, use the inflation device to connect to the air connection nozzle 13 on the lower inflation tube 11, and inflate the interior of all the air expandable airbags 2 through the lower inflation tube 11, the long connecting tube 14 and the airbag tube 6, and adjust the length of the air expandable airbag 2. At the same time, by observing the lower pressure gauge 1101, the length of the air expandable airbag 2 can be obtained until the total length of the support airbag 1 and the air expandable airbag 2 is equal to the width of the boat.

[0027] Through the above-mentioned arrangement, the total length of the support airbag 1 and the expandable airbag 2 can be adjusted to be equal to the width of the hull. At this time, the support airbag 1 can provide better support for the hull during use, preventing the hull from being insufficiently supported or the support airbag 1 from leaking out of the hull, making the support airbags 1 at different positions evenly stressed, thereby improving the supporting strength of the support airbag 1.

[0028] The gas switch valve 5 includes a valve body 501 fixedly connected to one of the connecting columns 3, and the two ends of the valve body 501 are respectively fixedly connected with inlet and outlet pipes 502, and one end of the two inlet and outlet pipes 502 is respectively fixedly connected to one end of the two through pipes 4 with a connecting pipe 503, a valve ring 504 is fixedly connected to the middle of the valve body 501, and a rotating shaft 505 is rotatably connected to the middle of the valve ring 504, and the outer wall of the rotating shaft 505 is fixedly connected to a closing fan 506 matching the valve ring 504, one end of the rotating shaft 505 extends to the outside of the valve body 501 and is fixedly connected to a gear 507, and one end of the other connecting column 3 is fixedly connected to a rack 508, and the rack 508 is meshed with the gear 507.

[0029] During the use of multiple support airbags 1, if one of the support airbags 1 is damaged, and since the multiple support airbags 1 are connected through the tube 4 and the air switch valve 5, the gas inside the remaining support airbags 1 will flow out through the damaged part, causing all the support airbags 1 to lose their support effect.

[0030] Through the above arrangement, when the air expandable airbag 2 is extended, the two connecting columns 3 move away from each other. At this time, the rack 508 drives the closing fan 506 to rotate through the gear 507 and the rotating shaft 505. During the rotation of the closing fan 506, the valve body 501 can be closed and opened. When the support airbag 1 is inflated, the air expandable airbag 2 is extended to the corresponding length to open the valve body 501, so that multiple support airbags 1 can be connected and inflated. When the support airbag 1 is fully inflated, the air expandable airbag 2 is extended to the corresponding length to close the valve body 501.

[0031] At this time, the multiple support airbags 1 are not connected to each other. When one of the support airbags 1 is damaged, the remaining support airbags 1 can still support the hull, further improving the support effect on the hull.

[0032] The second implementation method:

[0033] Figure 1-2 and Figure 6-7 A high-strength marine airbag is shown. Different from the first embodiment, the connecting column 3 is composed of an inner column 301 and an outer ring 302. The inner column 301 is fixedly connected to the air-expandable airbag 2, the outer ring 302 is fixedly connected to the supporting airbag 1, the inner column 301 and the outer ring 302 are threadedly connected, and the airbag tube 6 and the transfer tube 7 are threadedly connected.

[0034] Through the above arrangement, different numbers of support airbags 1 and air expansion airbags 2 can be disassembled or assembled, and the total length of the support airbag 1 can be increased or decreased, so that the device can be applied to hulls of a wider range of specifications.

[0035] A protective sheath 15 is provided between the plurality of supporting airbags 1 , and the protective sheath 15 is located outside the air-expandable airbag 2 . The above arrangement can protect the air-expandable airbag 2 .

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
