Description

Technical Field

[0001] This utility model belongs to the field of lifesaving equipment technology, and more specifically, relates to an air chamber connection structure and vessel for an inflatable rescue boat. Background Technology

[0002] With the continuous development of synthetic rubber and polymer materials, inflatable rescue boats have experienced rapid growth. Inflatable rescue boats expand by filling air chambers in the hull with gas (usually air or carbon dioxide), creating a hull with buoyancy and shape, capable of carrying personnel and supplies afloat on the water. They are generally equipped with an air pump to inflate the chambers, ensuring readiness for emergency use.

[0003] Existing inflatable rescue boats typically employ multiple independent air chambers. This design allows some chambers to remain inflated even if others are damaged, ensuring buoyancy. However, the current design necessitates individually inflating each chamber before use, a cumbersome and inconvenient process. Furthermore, under varying loads and high sea conditions, different chambers require different pressures to maintain balance. The existing chamber design makes it difficult to adjust pressure during use. Without pressure adjustment, the boat is prone to instability and capsizing due to load changes or rough seas, posing a safety hazard. Therefore, there is an urgent need for a rescue boat that is easy to inflate, can be inflated and deflated as needed to adjust hull shape, and ensures stability, comfort, and safety during navigation. Utility Model Content

[0004] One of the purposes of this utility model is to solve the problem that the inflation and deflation operations of existing inflatable rescue boats are inconvenient. It provides an air chamber connection structure for inflatable rescue boats. By designing this air chamber connection structure, it is convenient to perform individual or simultaneous inflation and deflation operations on different air chambers, which significantly improves inflation and deflation efficiency. Moreover, the air pressure of different air chambers can be conveniently adjusted in real time according to actual needs in different usage scenarios.

[0005] The second objective of this utility model is to provide a rescue boat equipped with the aforementioned air chamber connection structure. By assembling the aforementioned air chamber connection structure, the convenience of the boat's inflation and deflation operations is significantly improved, and the boat's self-righting function effectively ensures the stability, comfort, and safety of the boat's course.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] Firstly, the present invention provides an air chamber connection structure for an inflatable rescue boat, comprising an air inlet pipe, a gas distribution chamber, pipes, and a controller. The gas distribution chamber is located in one of the air chambers. The air inlet of the gas distribution chamber is connected to an external air pump through the air inlet pipe. The air outlet of the gas distribution chamber is connected to other air chambers through pipes, and each pipe is individually equipped with an air valve and a flow meter. The air valve and the flow meter are electrically connected to the controller.

[0008] As one embodiment of the first aspect of this utility model, the gas chamber communication structure further includes a connector, one end of which extends into the gas distribution chamber and is sealed to the side wall of the gas distribution chamber, and the other end of which is sealed to the pipeline.

[0009] As one embodiment of the first aspect of this utility model, a sealing gas pad is provided at the connection between the connector and the side wall of the gas distribution cavity, and the sealing gas pad is integrally disposed within the gas distribution cavity.

[0010] In one embodiment of the first aspect of this utility model, the air chamber is located at the bottom of the hull bottom plate, and a first air chamber, a second air chamber and a third air chamber are arranged sequentially along the length of the bottom plate, with the gas distribution chamber located in the second air chamber.

[0011] As one embodiment of the first aspect of this utility model, the pipeline includes a first pipeline, a second pipeline and a third pipeline. The first pipeline penetrates the partition panel and extends into the first air chamber, and the third pipeline penetrates the partition panel and extends into the third air chamber. A sealing element is provided at the connection between the first pipeline and the third pipeline and the partition panel.

[0012] As one embodiment of the first aspect of this utility model, the air chamber communication structure further includes a mounting base, which is detachably mounted on the bottom plate of the ship's hull, and the air intake pipe body is fixed on the mounting base.

[0013] As one embodiment of the first aspect of this utility model, the air chamber communication structure further includes a top cover, and the end of the air inlet pipe is threaded and threadedly connected to the top cover.

[0014] Secondly, this utility model provides an inflatable rescue boat, including a hull, wherein the air chamber at the bottom of the hull bottom plate is provided with the aforementioned air chamber communication structure.

[0015] As one embodiment of the first aspect of this utility model, a protective cover plate is also provided on the bottom plate of the hull, and the protective cover plate is sleeved above the air intake pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) The gas chamber connection structure of the inflatable rescue boat of this utility model, on the one hand, by setting the gas distribution chamber in a single gas chamber and using an external air pump connected to the air inlet pipe, and connecting it with other gas chambers through the pipeline, multiple gas chambers can be inflated simultaneously by a single air source during inflation, without the need to inflate each gas chamber individually, which significantly improves inflation efficiency and greatly shortens the preparation time for inflating the rescue boat, meeting the needs of rapid response in rescue scenarios; on the other hand, the pipeline is equipped with an air valve and a flow meter, which are electrically connected to the controller, and can be linked with the air valve and flow meter through the controller to automatically identify the air pressure of the gas chamber, which facilitates precise control of inflation flow; at the same time, in special environments, if it is necessary to adjust the shape of the hull to improve the stability of the boat during navigation, it can be achieved by inflation and deflation, which is easy to operate. In addition, by closing the corresponding air valve and cutting off the connection with the gas chamber distribution chamber, a single gas chamber can be independently inflated and deflated.

[0018] (2) The inflatable rescue boat of this utility model has an air chamber connection structure, which makes it easy to quickly inflate and deflate the boat before use. It is easy to operate. The boat with this structure can conveniently adjust the air chamber pressure according to the actual needs of the scene during navigation, so as to avoid the problem of the boat being unstable and easy to capsize due to the load or the wind and waves. Thus, the stability, comfort and safety of the boat during navigation are satisfied. Attached Figure Description

[0027] The present invention will be further described below with reference to specific embodiments.

[0028] Example 1

[0029] like Figure 1 and Figure 2 As shown in the figure, an inflatable rescue boat air chamber communication structure of this embodiment includes an air inlet pipe 203, a gas distribution chamber 204, a pipe and a controller. The gas distribution chamber 204 is located in one of the air chambers. The air inlet of the gas distribution chamber 204 is connected to an external air pump through the air inlet pipe 203. The air outlet of the gas distribution chamber 204 is connected to other air chambers through pipes. By setting the gas distribution chamber 204 to distribute the filled gas and then deliver it to different air chambers, multiple air chambers can be inflated simultaneously. Compared with the existing rescue boats that inflate each air chamber individually, the inflation efficiency is significantly improved, the operation is more convenient, and the preparation time for inflating the rescue boat is greatly shortened, which meets the needs of rapid response in rescue scenarios.

[0030] In the gas chamber communication structure 2 of this embodiment, each pipe connected to the gas distribution chamber 204 is individually equipped with a gas valve and a flow meter. Figure 1 (Not shown in the diagram), the air valve and flow meter are both connected to the controller ( Figure 1(Not shown in the diagram) Electrical connections. This structural design enables intelligent control and on-demand distribution of inflation and deflation. Through the controller's linkage with the air valve and flow meter, on one hand, the flow meter's feedback data can automatically identify the air pressure in the air chamber; on the other hand, the inflation flow rate can be precisely controlled by adjusting the air valve opening. Furthermore, in case of rough seas during navigation, inflation and deflation can be used to improve the vessel's stability, and the operation is simple.

[0031] As another implementation method of this embodiment, such as Figure 2 As shown, the gas chamber communication structure 2 in this embodiment also includes a connector 205. One end of the connector 205 extends into the gas distribution chamber 204 and is sealed to the side wall of the gas distribution chamber 204. The other end of the connector 205 is sealed to the pipeline. Specifically, a rubber sealing gas pad 212 is provided at the connection between the connector 205 and the side wall of the gas distribution chamber 204. The sealing gas pad 212 is integrally disposed within the cavity of the gas distribution chamber 204. In this embodiment, the gas distribution chamber 204 is designed as a sphere. To ensure sealing, the sealing gas pad 212 is processed into a funnel-shaped structure with a pipeline inserted through its center. The side wall of the sealing gas pad 212 is tightly attached to the side wall of the gas distribution chamber 204, and the end of the sealing gas pad 212 is embedded at the connection between the gas distribution chamber 204 and the pipeline, thus achieving a sealing function.

[0032] Example 2

[0033] Combination Figure 3 This embodiment of an inflatable rescue boat air chamber communication structure is basically the same as that of Embodiment 1, except that the air chambers are located at the bottom of the hull 1 bottom plate, and a first air chamber 101, a second air chamber 102, and a third air chamber 103 are arranged sequentially along the length of the hull 1 bottom plate. The gas distribution chamber 204 is located in the second air chamber 102. In this embodiment, a cavity is set at the bottom of the hull 1 bottom plate, and two partition panels 104 are set in the cavity to divide the bottom cavity into three independent air chambers. The two partition panels 104 are correspondingly machined with mounting holes for pipe installation.

[0034] The pipeline includes a first pipeline 209, a second pipeline 210, and a third pipeline 211. The first pipeline 209 penetrates the bulkhead 104 and extends into the first air chamber 101. The third pipeline 211 penetrates the bulkhead 104 and extends into the third air chamber 103. Sealing elements are provided at the connections between the first pipeline 209 and the third pipeline 211 and the bulkhead 104. The second pipeline 210 is located within the second air chamber 102. This completes the installation of the air chamber communication structure 2 on the hull 1. Furthermore, the air chamber communication structure 2 in this embodiment also includes a mounting base 202, which is disposed outside the air chamber. The mounting base 202 is detachably mounted on the bottom plate of the hull by screws. An opening is machined on the bottom plate of the hull for the air intake pipe 203 to pass through. The air intake pipe 203 is fixed on the mounting base 202, which improves the stability of the installation of the air chamber communication structure 2. In order to ensure the sealing of the second air chamber 102, the connection between the bottom plate of the hull and the air intake pipe 203 is also sealed.

[0035] In addition, the air chamber communication structure 2 in this embodiment also includes a top cover 201. The end of the air inlet pipe 203 is threaded and connected to the top cover 201. After inflation, the top cover 201 can be closed to seal and prevent air leakage.

[0036] In addition, it should be noted that the first pipe 209, the second pipe 210 and the third pipe 211 are respectively connected to the first air valve 206, the second air valve 207 and the third air valve 208 via flanges or threads. The first air valve 206, the second air valve 207 and the third air valve 208 are all solenoid valves, and their corresponding pipes are all sealed. The air valves are electrically connected to the controller. The controller can control the opening degree and closing degree of the valves to realize the convenient inflation and deflation process of the hull 1.

[0037] The working principle of the air chamber connection structure of the rescue boat in this embodiment is explained below:

[0038] The rescue boat participated in a maritime rescue mission, during the rapid inflation phase:

[0039] Connect the air inlet pipe 203 to the air pump, power the controller, and fully open the first air valve 206, the second air valve 207, and the third air valve 208. Power the air pump to start filling the air chamber. The gas enters the gas distribution chamber 204 through the air inlet pipe 203, and then fills the corresponding air chambers through the first pipe 209, the second pipe 210, and the third pipe 211 respectively. The flow meter collects the gas pressure in each pipe in real time. When the pressure in a certain air chamber reaches the preset value, the opening of the air valve on the corresponding pipe can be reduced to allow more gas to be distributed to the other pipes through the gas distribution chamber 204, quickly completing the filling stage, instead of maintaining the current flow rate to continue distributing to the current air chamber, causing the current air chamber pressure to be too high.

[0040] During navigation, if the ship turns or there are large waves, the air pressure in the air chamber needs to be adjusted accordingly. This can be done by connecting and turning on the air pump to continue filling the air, or by removing the air pump to release the gas in the air chamber.

[0041] In an emergency, if the ship is damaged, the flow meter can quickly detect an abnormal drop in air pressure (e.g., the air pressure in the damaged air chamber drops by ≥0.1MPa within 10 seconds). The controller will automatically close the corresponding air valve and disconnect the faulty air chamber from the distribution chamber. The remaining air chambers will continue to maintain pressure to meet the needs of safe personnel transfer.

[0042] Example 3

[0043] like Figure 3 As shown, in this embodiment of an inflatable rescue boat, an air chamber communication structure 2 as described in embodiment 2 is provided in the air chamber at the bottom of the bottom plate of the hull 1, and a protective cover plate is also provided on the bottom plate of the hull 1. Figure 3 (Not shown in the drawing) The protective cover is fitted over the air intake pipe 203 and is fixedly connected to the bottom plate of the hull 1. The top plate of the protective cover has an openable design, which can be opened when in use and closed when not in use. The cavity formed by the protective cover can also accommodate the controller, power supply and air pump. The connection between the protective cover and the bottom plate of the hull, as well as the top plate and side walls of the protective cover, are all designed to be sealed to prevent water vapor from entering.

[0044] In addition, the rescue boat is also equipped with oars, life jackets, emergency kits and other life-saving items to meet rescue needs.
