Description

Technical Field

[0001] This utility model relates to the field of lifeboat technology, specifically to a lifeboat capable of rapid rescue. Background Technology

[0002] Inflatable boats (also known as pneumatic lifeboats) are widely used in water rescue, flood control and disaster relief, maritime operations, and recreational activities due to their advantages such as being lightweight, foldable, easy to transport, and quick to deploy. In emergency rescue scenarios, inflatable boats are often used temporarily or formally as lifeboats, especially suitable for transferring personnel in inland rivers, lakes, shallow near-shore waters, and when ships are moored. However, in actual use, because lifeboats have a high hull height and are usually not equipped with gangways, it is difficult for stranded personnel to board during rescue operations. Currently, rescuers often rely on assistance or towing to get them onto the lifeboat, which restricts the overall rescue speed in emergency rescues. Therefore, based on the above problems, existing technologies need further improvement. Utility Model Content

[0003] The purpose of this invention is to provide a lifeboat that enables rapid rescue, thereby solving the existing technical problems described in the background section.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a lifeboat capable of rapid rescue is provided, including a lifeboat body, an inflatable air chamber, and a rescue air chamber. The inflatable air chamber and the rescue air chamber are both disposed within the hollow structure of the lifeboat body. At least two inflatable air chambers are provided, and the rescue air chamber is disposed between the inflatable air chambers. Spacer membranes are provided between the inflatable air chambers and between the inflatable air chambers and the rescue air chamber to form independent air chambers. An inflation valve is provided on each inflatable air chamber and the rescue air chamber. A connecting device for controlling the connection between the various air chambers is also provided on the spacer membrane.

[0005] Based on the above technical solution, the communication device includes an opening and a control valve on the spacer membrane. The opening is controlled to open and close by the control valve and is used for communication between inflation chambers and between inflation chambers and rescue chambers.

[0006] Based on the above technical solution, the length of the rescue air chamber accounts for 10-20% of the length of the lifeboat body.

[0007] Based on the above technical solution, the length of the rescue air chamber accounts for 14% of the length of the lifeboat body.

[0008] Based on the above technical solution, three inflation chambers are provided.

[0009] Based on the above technical solution, the lifeboat body is U-shaped and is provided with a first inflation chamber, a second inflation chamber, a rescue chamber and a third inflation chamber in sequence.

[0010] Based on the above technical solution, the normal operating air pressure range inside the lifeboat body is 20kPa-35kPa.

[0011] Based on the above technical solution, the inflation chamber and the rescue chamber are inflated using a manual pump, an electric inflation pump, or a high-pressure air cylinder.

[0012] The beneficial effects of the technical solution provided by this utility model are as follows: This utility model provides a lifeboat capable of rapid rescue. The lifeboat body is equipped with rescue air chambers. When a rescue is needed, these chambers can be rapidly deflated to lower the height of the rescue passage, facilitating rescue and increasing efficiency. Simultaneously, after the rescue, a connecting device enables gas communication between the chambers, allowing for refilling and quickly meeting the lifeboat's normal operating requirements. Overall, this design improves rescue efficiency, reduces rescue difficulty, and possesses excellent practical performance. Attached Figure Description

[0013] Figure 1 This is an internal cross-sectional view of this utility model; Detailed Implementation The present invention will be further described below with reference to the accompanying drawings and embodiments: In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0014] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figure 1As shown, a lifeboat capable of rapid rescue includes a lifeboat body 1, an inflatable air chamber, and a rescue air chamber 2. The inflatable air chamber and the rescue air chamber are both located within the hollow structure of the lifeboat body 1. There are at least two inflatable air chambers. The rescue air chamber 2 is located between the inflatable air chambers. Spacer membranes 3 are provided between the inflatable air chambers and between the inflatable air chambers and the rescue air chamber 2 to form independent air chambers. Inflation valves 4 are provided on the inflatable air chambers and the rescue air chambers. A connecting device for controlling the connection between the various air chambers is also provided on the spacer membrane 3.

[0016] This utility model provides a lifeboat capable of rapid rescue. The lifeboat body is equipped with rescue air chambers. When a rescue is needed, these chambers can be rapidly deflated to lower the height of the rescue passage, facilitating rescue and increasing efficiency. Simultaneously, after the rescue, a connecting device enables gas communication between the chambers, allowing for refilling and quickly meeting the lifeboat's normal operating requirements. Overall, this design improves rescue efficiency, reduces rescue difficulty, and possesses excellent practical performance.

[0017] Specifically, in the initial state, multiple inflation chambers and a rescue chamber are inflated to ensure that each chamber meets the required air pressure. Under normal use, the connecting device between the chambers is closed, meaning that each chamber is completely independent through the spacer membrane between them. During a rescue operation, the inflation valve of the rescue chamber is opened to release air and lower the height of the rescue chamber to facilitate the rescue. After the rescue is completed, the height of the rescue chamber is restored to normal use.

[0018] Preferably, when inflating the inflation chamber and the rescue chamber, inflation can be performed separately through the inflation valve on each chamber; or the connecting device between the chambers can be opened, and the inflation valve of one chamber can be used to inflate it, thus completing the inflation operation of multiple inflation chambers and the rescue chamber. After inflation is completed, the connecting device can be closed.

[0019] Preferably, after the rescue is completed, the rescue air chamber can be individually inflated via its inflation valve; or the connecting device between the air chambers can be opened to connect the air chambers and use the gas in other inflatable air chambers to replenish the air volume missing in the rescue air chamber. The balanced air pressure can meet the normal air pressure requirements of the lifeboat so that it can safely travel to a safe area. It can replenish air without carrying an additional air pump, making the operation more convenient.

[0020] Based on the above technical solution, the communication device includes an opening 5 provided on the spacer membrane 3 and a control valve. The opening 5 is controlled to open and close by the control valve and is used for communication between the inflation chambers and between the inflation chamber and the rescue chamber 2.

[0021] Based on the above technical solution, the length of the rescue air chamber 2 accounts for 10-20% of the length of the lifeboat body 1.

[0022] Preferably, by setting a rescue air chamber, not only can rapid rescue be achieved, but its length is also relatively small compared to other air chambers. More preferably, the length of the rescue air chamber is between 10-20% of the length of the lifeboat body, which can not only meet the needs of rescue after deflation, but also allow for rapid inflation after the rescue is completed.

[0023] Based on the above technical solution, the length of the rescue air chamber 2 accounts for 14% of the length of the lifeboat body 1.

[0024] Based on the above technical solution, three inflation chambers are provided.

[0025] Based on the above technical solution, the lifeboat body 1 is U-shaped and is provided with a first inflation chamber 6, a second inflation chamber 7, a rescue chamber 2 and a third inflation chamber 8 in sequence.

[0026] Based on the above technical solution, the normal operating air pressure range inside the lifeboat body 1 is 20kPa-35kPa.

[0027] Based on the above technical solution, the inflation chamber and the rescue chamber 2 are inflated using a manual pump, an electric inflation pump, or a high-pressure air cylinder.

[0028] In this embodiment, with the length of the rescue air chamber 2 accounting for 14% of the length of the lifeboat body 1, the air volume of the lifeboat before and after rescue is described in detail to prove that the lifeboat in this application can meet the requirements for normal use while achieving rapid rescue, as detailed below.

[0029] The normal operating air pressure range of the rubber boat is 20kPa-35kPa (101kPa under standard atmospheric pressure). Assuming the air pressure after inflation is 35kPa; since the rescue air chamber is 14% of the boat length, let the boat length be 'a', then the rescue air chamber is 0.14a. The gas volume during the rescue was 2 - 2 (The total air column is approximately twice the length of the ship.) The air volume after rebalancing following the rescue is: 2 a*2; According to Boyle's law, if a gas changes from state 1 (P1, V1) to state 2 (P2, V2) while the temperature and mass remain constant, then: P1V1 = P2V2; that is, the gas pressure multiplied by the volume is equal before and after the rescue. Assuming the equilibrium pressure is x kPa, then: ( 2 - 2 ) * (101 + 35) = 2 *(101+x), by calculation we get x=25.48.

[0030] Therefore, the initial air pressure of each air chamber of the rubber boat is 35 kPa. During the rescue, air chamber No. 2 is deflated (assuming complete deflation). After the rescue is completed, the connecting valve is opened, and the air pressure value after the air pressure of each air chamber is balanced is about 25.48 kPa, which fully meets the usage requirements.

[0031] The foregoing has shown and described the basic principles and main features of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments. Therefore, the embodiments should be regarded as exemplary and non-limiting. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims within this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
