Description

Technical Field

[0001] This invention relates to the field of ocean-going inflatable lifesaving equipment technology, and in particular to an inflatable vessel with a split-type quick-release air supply device. Background Technology

[0002] With the development of the national economy, water-based production and life have also developed significantly, especially cruise tourism and open-sea operations. However, this development has also increased the probability of water safety accidents. In order to improve the survival rate of people who fall into the water after a water safety accident, life-saving equipment needs to be installed on ocean-going vessels and cruise ships. For easy storage, it is necessary to make full use of the limited space on board. Therefore, inflatable boats are becoming increasingly popular in the marine life-saving industry due to their high compressibility. Current inflatable lifeboats are simply compressed from the original hull. For ease of use, built-in inflation equipment is installed inside. However, due to the special nature of their structure and purpose, it is impossible to maintain and test the internal drive unit in a routine manner, making operation difficult. Moreover, it will increase the overall weight of the hull, making it very inconvenient to transport and store. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the background art, an improved inflatable boat with a split quick-release air supply device is provided. This solves the problem that the current inflatable lifeboats are simply compressed from the original hull. For ease of use, a built-in air supply device is installed inside. However, due to the special nature of its structure and purpose, it is impossible to maintain and test the internal drive unit in daily life. The operation is difficult and it will also increase the weight of the entire hull, making it very inconvenient to transport and store.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an inflatable boat with a split-type quick-release air supply device, including a main hull composed of flexible inflatable airbags and a main air tank filled with high-pressure gas. The main hull is composed of a central assembly frame, a flexible inflatable base fixed to the outside of the central assembly frame, and a flexible inflatable baffle fixed to the outside of the flexible inflatable base. An internal assembly tube is axially fixed on the inner bottom surface of the central assembly frame. A water-immersed elastic striking pin module is fixedly installed on the inner bottom surface of the internal assembly tube. A transverse lateral air supply pipe communicating with the inside of the flexible inflatable base is provided on the outer surface of the internal assembly tube. The lower end of the main air tank is threadedly connected to the outside of the internal assembly tube and threadedly fixed to the internal assembly tube through a bottom internal threaded assembly tube.

[0005] The outer side of the internal assembly pipe is provided with a lateral water inlet hole located around the water-immersed elastic impact pin module.

[0006] The flexible inflatable base and flexible inflatable edge have multiple integrated internal sealing covers and flexible internal air supply pipes that run through the internal sealing covers.

[0007] A built-in check valve is fixedly installed on the inner side of the flexible internal gas pipeline.

[0008] A side-mounted inflatable life jacket is attached to the outer surface of the flexible inflatable baffle.

[0009] The upper end of the outer side of the flexible inflatable baffle has an upwardly protruding external threaded mounting tube. The side-mounted inflatable life jacket is connected to the flexible inflatable baffle by an internal threaded connecting tube at the top of the outer side, which is sleeved on the outside of the external threaded mounting tube.

[0010] Both the external threaded mounting pipe and the internal threaded connecting pipe are equipped with one-way check valves. The one-way check valve on the inner side of the internal threaded connecting pipe is elastically fitted with a telescopic control pipe.

[0011] The main gas tank has an upward-protruding upper control handle at its top.

[0012] The outer side of the main gas tank has an outwardly protruding lateral limiting ring.

[0013] The beneficial effects of this invention are:

[0014] (1) The inflatable boat with a split quick-release air supply device of the present invention has a split design of the drive unit and the hull, which can facilitate daily storage and folding of the hull without affecting normal use.

[0015] (2) The split design allows for separate maintenance and testing in daily life, reducing the difficulty and cost of later maintenance;

[0016] (3) The threaded quick-connect design makes assembly before use convenient and the operation is very simple.

[0017] (4) The inflatable boat adopts a detachable structure design, which allows the main air tank to be disassembled and discarded after inflation, thereby enhancing the load-bearing capacity of the inflatable boat.

[0018] (5) By using the externally mounted side-mounted inflatable life jacket, the occupant's personal life-saving equipment can be inflated simultaneously, and the separation is convenient, greatly improving safety. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Figure 1 , Figure 2 and Figure 3 The inflatable boat shown includes a main hull composed of flexible inflatable airbags and a main gas tank 1 filled with high-pressure gas. The main hull consists of a central assembly frame 2, a flexible inflatable base pad 3 fixed to the outside of the central assembly frame 2, and a flexible inflatable baffle 4 fixed to the periphery of the flexible inflatable base pad 3. An internal assembly tube 5 is axially fixed on the inner bottom surface of the central assembly frame 2. A water-immersed elastic impact pin module 6 is fixedly installed on the inner bottom surface of the internal assembly tube 5. A transverse lateral gas supply pipe 7 connected to the inside of the flexible inflatable base pad 3 is provided on the outer surface of the internal assembly tube 5. The lower end of the main gas tank 1 is threadedly connected to the outside of the internal assembly tube 5 and threadedly fixed to the internal assembly tube 5 through a bottom internal thread assembly tube 8.

[0026] To facilitate lateral air intake, the outer side of the internally mounted pipe 5 is provided with a lateral water inlet hole 9 located around the water-immersed elastic impact pin module 6.

[0027] Water enters from the side through the side water inlet hole 9 and flows into the water-immersed elastic striking pin module 6. After being immersed in water, the water-immersed elastic striking pin module 6 softens, and the elastic striking pin inside the water-immersed elastic striking pin module 6 extends towards the main air tank 1 and punctures the sealing cap at the lower end of the main air tank 1. At this time, the high-pressure air inside the main air tank 1 is introduced into the flexible inflatable base pad 3 through the horizontal side air supply pipe 7.

[0028] The side water inlet 9 can guide water inward, but when the water-immersed elastic striker module 6 is activated, the internal elastic striker will automatically close the side water inlet 9.

[0029] To enhance safety, the flexible inflatable base pad 3 and the flexible inflatable side guard 4 have multiple integrated internal sealing covers 10 and flexible internal air supply pipes 11 that run through the internal sealing covers 10.

[0030] To facilitate inflation of the flexible inflatable base pad 3 and the flexible inflatable sidewall 4, and to prevent air leakage, a built-in check valve 12 is fixedly installed on the inner side of the flexible internal air supply pipe 11.

[0031] To enhance the expandability of external functions, a side-mounted inflatable life jacket 13 is attached to the outer side of the flexible inflatable baffle 4.

[0032] To facilitate threaded loading and unloading, the upper part of the outer side of the flexible inflatable baffle 4 has an upwardly protruding external threaded mounting tube 14. The side-mounted inflatable life jacket 13 is connected to the flexible inflatable baffle 4 by the internal threaded connecting tube 15 at the outer top of the jacket, which is fitted onto the outside of the external threaded mounting tube 14.

[0033] In order to keep the side-mounted inflatable life jacket 13 connected to the inside of the flexible inflatable baffle 4 when it is attached externally, and to prevent air leakage from the outside when it is separated, both the external threaded mounting pipe 14 and the internal threaded connecting pipe 15 are equipped with one-way check valves. The one-way check valve on the inner side of the internal threaded connecting pipe 15 is elastically fitted with a telescopic interlocking pipe 155.

[0034] When the internal threaded connecting pipe 15 is fitted onto the outside of the external threaded mounting pipe 14, the telescopic interlocking pipe 155 is inserted into the one-way check valve inside the external threaded mounting pipe 14, controlling the one-way check valve inside the external threaded mounting pipe 14 to open. At the same time, the telescopic interlocking pipe 155 squeezes the one-way check valve inside the internal threaded connecting pipe 15 due to the reaction force, controlling the one-way check valve inside the internal threaded connecting pipe 15 to open, thereby connecting the external threaded mounting pipe 14 and the internal threaded connecting pipe 15.

[0035] Conversely, when the internal threaded connecting pipe 15 is disassembled from the outside of the external threaded mounting pipe 14, the one-way check valve inside the external threaded mounting pipe 14 and the internal threaded connecting pipe 15 elastically prevents backflow and closes the openings of the internal threaded connecting pipe 15 and the external threaded mounting pipe 14.

[0036] To facilitate the control of the rotation of the main gas tank 1, the top of the main gas tank 1 has an upward-protruding upper control handle 16.

[0037] To enhance the lateral limiting capability after assembly, the outer side of the main gas tank 1 has an outwardly protruding lateral limiting ring 17.

[0038] This invention discloses an inflatable boat with a split-type quick-release air supply device. The drive unit and hull are designed separately, which facilitates daily storage and easy folding of the hull without affecting normal use. The split design allows for separate maintenance and inspection in daily life, reducing the difficulty and cost of later maintenance. The threaded quick-release design facilitates assembly before use and is very simple to operate. The detachable structure design allows the main air tank 1 to be removed and discarded after inflation, thereby enhancing the load-bearing capacity of the inflatable boat. The externally mounted side-mounted inflatable life jacket 13 allows for simultaneous inflation of the occupants' personal life-saving equipment, and the separation is convenient, greatly improving safety.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
