Description

Technical Field

[0001] This utility model belongs to the field of marine airbag technology, specifically relating to a reusable marine airbag. Background Technology

[0002] Ship airbags utilize the buoyancy generated by the high-pressure gas inside after inflation to support the weight of the ship. Through their own elasticity and flexibility, the weight of the ship is evenly distributed across multiple airbags. They can also serve as rolling fulcrums, allowing the ship to move smoothly to a predetermined position by rolling.

[0003] Most existing propulsion airbags are single-layer inflatable structures. When a ship is launched, the airbags mainly serve a supporting function. However, if the airbags are damaged or the pressure is insufficient, the bottom of the ship is prone to scraping against the ground, which increases the frictional resistance during the launch. Therefore, it is easy to cause problems such as a limited number of times the airbags can be reused. Utility Model Content

[0004] The purpose of this invention is to provide a reusable ship airbag that can be configured as a double-layer airbag structure. If the pressure of the outer airbag is insufficient, the inner airbag can be used to support the bottom of the ship.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A reusable ship airbag includes an outer airbag and an inner airbag. The inner airbag is located inside the cavity of the outer airbag. An air inlet pipe is fixedly connected to the side wall of the inner airbag. The air inlet pipe passes through the outer airbag and is connected to a one-way air inlet assembly. The air inlet pipe communicates with both the outer airbag and the inner airbag.

[0007] Furthermore, the one-way air intake assembly includes a connecting pipe fixedly connected to the end face of the air intake pipe. The inner wall of the connecting pipe is inclined. A valve core is provided in the inner cavity of the connecting pipe. The valve core abuts against the inclined surface of the inner wall of the connecting pipe. A spring is fixedly connected between the valve core and the inner wall of the connecting pipe.

[0008] Furthermore, a connector is fixedly connected to the other end of the connecting pipe.

[0009] Furthermore, a tapered tube is fixedly connected to the inner wall of the air intake pipe, and several air outlet holes are opened on the side wall of the air intake pipe between the outer airbag and the inner airbag.

[0010] Furthermore, the outer airbag and the inner airbag are fixedly connected by a traction rope at a point away from the air intake pipe.

[0011] Furthermore, traction rings are fitted to the sidewalls of the outer airbag near both ends.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention relates to a reusable marine airbag. Through the cooperation of an outer airbag, an inner airbag, and an air intake pipe, the airbag is designed as a double-layer airbag structure. If the pressure of the outer airbag is insufficient, the inner airbag can provide support for the bottom of the ship. When the outer airbag is compressed, some of the pressure can be transferred to the inner airbag to increase its strength and prevent the bottom of the airbag from scraping against the ground. This design can extend the service life of the airbag and increase the number of times it can be reused. Attached Figure Description

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-5 As shown, a reusable marine airbag includes an outer airbag 1 and an inner airbag 2. The inner airbag 2 is located inside the cavity of the outer airbag 1. An air inlet pipe 3 is fixedly connected to the side wall of the inner airbag 2. The air inlet pipe 3 penetrates the outer airbag 1 and is connected to a one-way air inlet assembly. The air inlet pipe 3 communicates with both the outer airbag 1 and the inner airbag 2. The outer airbag 1 has a wear-resistant layer structure on its surface, which can resist pressure and friction from the ship and the ground, extending its service life.

[0023] like Figure 4 and Figure 5As shown, the one-way air intake assembly includes a connecting pipe 4 fixedly connected to the end face of the air intake pipe 3. The inner wall of the connecting pipe 4 is inclined. A valve core 5 is provided in the inner cavity of the connecting pipe 4. The valve core 5 abuts against the inclined surface of the inner wall of the connecting pipe 4. A spring 6 is fixedly connected between the valve core 5 and the inner wall of the connecting pipe 4.

[0024] The one-way inflation assembly utilizes the principle of a one-way valve to control the leakage of gas from the outer airbag 1 and the inner airbag 2. It can be inflated directly during inflation, and when it is necessary to deflate, a rod-shaped object is inserted into the connector 7, which is then pressed against the valve core 5 to open the valve core 5, thereby achieving depressurization.

[0025] like Figure 1 and Figure 3 As shown, the other end of the connecting pipe 4 is fixedly connected to a connector 7. The connector 7 is a quick connector, which facilitates connection to external gas supply equipment.

[0026] like Figure 5 As shown, a conical tube 8 is fixedly connected to the inner wall of the air intake pipe 3, and several air outlets 9 are opened on the side wall of the air intake pipe 3 between the outer airbag 1 and the inner airbag 2. When the airflow enters the air intake pipe 3, it can be divided by the conical tube 8 and the air outlets 9, which facilitates the synchronous inflation of the outer airbag 1 and the inner airbag 2. In addition, the structure of the air outlets 9 also facilitates the interaction between the outer airbag 1 and the inner airbag 2.

[0027] like Figure 3 and Figure 4 As shown, a towing rope 10 is fixedly connected to the outer airbag 1 and the inner airbag 2 at a location away from the air intake pipe 3. The towing rope 10 is used to support the tail end of the inner airbag 2, ensuring that the inner airbag 2 is always in the middle position inside the outer airbag 1 when inflated, thereby achieving dual protection for the ship, extending its service life, and increasing the number of times it can be reused.

[0028] like Figure 1 and Figure 2 As shown, traction rings 11 are fitted on the sidewalls of the outer airbag 1 near both ends.

[0029] The outer airbag 1 can be limited by the traction ring 11. By attaching a rope to the traction ring 11, the airbag can be quickly retrieved after it falls into the water without the need for salvage.

[0030] The working principle of this utility model is as follows: First, it is connected to an external air supply facility through connector 7, and gas is injected into the outer airbag 1 and the inner airbag 2. During the injection process, the internal pressure of the outer airbag 1 and the inner airbag 2 can be observed through a pressure gauge. While inflating, the valve core 5 is opened by the impact force of the airflow, and the spring 6 is compressed at the same time. After inflation is completed, the spring 6 rebounds and the valve core 5 abuts against the inclined surface of the inner wall of the connecting pipe 4 for sealing. When the airflow enters the air inlet pipe 3, part of the gas enters the outer airbag 1 through the air outlet 9, and the other part of the gas enters the inner airbag 2 through the conical pipe 8. During the support of the ship, when the outer airbag 1 is compressed, the gas inside it can enter the inner airbag 2 to provide auxiliary support for the ship and avoid insufficient pressure in the outer airbag 1, which could cause the ship to bottom out, thus effectively improving its performance.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
