Technical Field

[0001] The utility model relates to buoyancy equipment for ships, in particular to a convenient-to-use foldable ship buoyancy device. Background Art

[0002] With the increasing number of water activities, foldable boats, as a portable and easy-to-store water transportation tool, have been favored by the majority of users. However, traditional foldable boats often have problems such as insufficient buoyancy and poor stability when facing wind and waves, excessive load or long-term use, which not only affects the user experience but also may bring safety hazards. Therefore, how to improve the buoyancy performance of foldable boats while maintaining their portability has become a problem that needs to be solved urgently.

[0003] At present, there are some devices on the market for enhancing the buoyancy of foldable boats, but most of these devices have the following shortcomings: first, they are bulky and inconvenient to carry and store; second, they are complicated to install, requiring professional skills and inflation tools; third, the connection method with the foldable boat is fixed and cannot adapt to foldable boats of different models and specifications.

[0004] Therefore, it is necessary to design a new type of buoyancy device that can simplify the structure and operation method, improve the convenience of use, and thus meet people's outdoor wading needs. Utility Model Content

[0005] In order to solve the above problems, the embodiment of the utility model provides a foldable boat buoyancy device that can be used without inflatable equipment.

[0007] As a further improvement of the above technical solution:

[0008] The number of the floating barrels is multiple and evenly distributed along the length of the first protective plate. The interlayer is provided with multiple storage cavities corresponding to the number and positions of the floating barrels, and a pre-folding line is provided between two adjacent storage cavities.

[0009] The first protective plate and the second protective plate are distributed in a V shape, and the opening distance gradually decreases from top to bottom.

[0010] The floating barrel includes two V-shaped base plates, the upper parts and surrounding parts of the two base plates are connected by flexible folding plates, and a gas nozzle extending to the outside of the interlayer is arranged in the middle of the flexible folding plate at the top, and a sealing end cover is arranged on the gas nozzle.

[0011] The elastic member is a spring, and two ends of the spring are respectively connected to the two substrates.

[0012] A Velcro strip for connecting the foldable boat is provided on a side of the first protective plate facing away from the second protective plate.

[0013] The beneficial effects of the embodiments of the utility model are as follows: 1. The foldable boat buoyancy device comprises a first protective plate and a second protective plate, wherein an interlayer is arranged between the first protective plate and the second protective plate, wherein a floating barrel providing buoyancy for the foldable boat is arranged in the interlayer, wherein an elastic member for propping up the floating barrel is arranged in the floating barrel, and the elastic member is used to replace the inflatable device to open the entire buoyancy device, thereby greatly improving the convenience of using the buoyancy device, and eliminating the need to carry an inflatable device.

[0014] 2. The entire buoyancy device has a simple structure and can be detachably connected to the folding boat, so it can be applied to more types of folding boats, thereby improving the application scope of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] like Figure 1-4As shown, the foldable boat buoyancy device of this embodiment includes a first protective plate 1 and a second protective plate 2, an interlayer 3 is provided between the first protective plate 1 and the second protective plate 2, a float barrel 4 providing buoyancy for the foldable boat is provided in the interlayer 3, an elastic member 5 for propping up the float barrel 4 is provided in the float barrel 4, the float barrel 4 is placed in the interlayer and is detachably connected to the interlayer 3, when in use, the float barrel is propped up by the elastic member 5, and the volume of the float barrel 4 increases after inhaling air, so as to provide buoyancy for the foldable boat, when stored, the air in the float barrel 4 is discharged to flatten the float barrel 4, and then the first protective plate 1 and the second protective plate 2 are squeezed inwardly, so that the whole buoyancy device is flat, and then it is folded based on the width of the float barrel 4, so as to reduce the floor space of the whole buoyancy device, compared with the existing buoyancy device, it has the advantages of convenient storage and carrying, and the inflation operation of the float barrel 4 can be realized without carrying an inflation device.

[0023] There are multiple floats 4 that are evenly distributed along the length of the first protective plate 1. The interlayer 3 is provided with multiple storage cavities 6 corresponding to the number and positions of the floats 4. A pre-folding line 7 is provided between two adjacent storage cavities 6. The design of the pre-folding line 7 can improve the wear resistance of the folding part during multiple folding and unfolding, thereby improving the service life of the entire equipment.

[0024] The first protective plate 1 and the second protective plate 2 are distributed in a V-shape, and the opening distance gradually decreases from top to bottom. The larger end of the V-shaped design is located at the upper part when in use, which can better maintain the stability of the foldable boat during the floating process while providing buoyancy.

[0025] The float 4 includes two base plates 8 distributed in a V-shape, and the upper parts and surrounding parts of the two base plates 8 are connected by flexible folding plates 9. The middle part of the flexible folding plate 9 located at the top is provided with an air nozzle 10 extending to the outside of the interlayer 3. A sealing end cover 11 is provided on the air nozzle 10. The sealing end cover 11 controls the entry and exit of other parts in the float 4 to better maintain the state of the float when it is stored or unfolded.

[0026] The elastic member 5 is a spring 12 , and both ends of the spring 12 are respectively connected to the two substrates 8 . A torsion spring or an elastic member made of other elastic materials may also be used.

[0027] A Velcro 13 for connecting to the foldable boat is provided on the side of the first protective plate 1 facing away from the second protective plate 2. The connection via the Velcro 13 has a simple structure and is easy to operate, and can quickly complete the connection and disassembly with the foldable boat. In order to improve the stability of the connection, a strap is designed on the upper part of the first protective plate 1 for tying to the side of the foldable boat, which can improve the connection stability of the two based on the connection of the Velcro 13.

[0028] When in use, first connect the first protective plate 1 to the foldable boat through Velcro, and then open the sealing end cover 11. At this time, the elastic member 5 will open the two base plates 8 to allow air to enter the float 4, and then tighten the sealing end cover 11 to avoid a decrease in buoyancy after air leakage. After use, remove the entire buoyancy device from the foldable boat, unscrew the sealing end cover 11 to squeeze the two base plates 8, and empty the air in the float 4 to make the entire float 4 flat, and then tighten the sealing end cover 11 for storage. The sealing end cover 11 not only plays a sealing role, but also stabilizes the state of the float 4.

[0029] It should be noted that the buoyancy device provided in this embodiment can not only be used for folding boats, but can also be used as a separate buoyancy device for backup, and has the advantages of occupying a small area and being usable without the need for inflatable equipment.

[0030] Example 2

[0031] Different from Example 1, Figure 5 As shown, the buoyancy device provided in this embodiment is connected to the folding boat as a whole, the first protective plate 1 is fixedly connected to the outer wall of the folding boat, and then the bottom of the second protective plate 2 is connected to the bottom of the first protective plate 1, and the two are distributed in a V shape. A flexible folding plate 9 is installed at the connection between the first and second protective plates 1 and 2. The upper opening position is sealed by a waterproof cloth 14. The waterproof cloth 14 is provided with an air nozzle 10, and the air nozzle 10 is provided with a sealing end cover 11. An elastic member 5 is directly installed between the inner walls of the first protective plate 1 and the second protective plate 2. When it is needed, the sealing end cover 11 is directly opened. At this time, the elastic member 5 opens the first protective plate 1 and the second protective plate 2 to form a floating barrel structure. Compared with Example 1, the buoyancy device provided in this embodiment has a simpler structure, is suitable for shallow water areas or temporary rescue boats, and has the advantage of being stored as one with the folding boat without disassembly.
