Description

Technical Field

[0001] The utility model relates to the technical field of inflatable boats, in particular to a high-pressure and rapid inflation system for inflatable boats. Background Art

[0002] When a ship is sailing on the sea surface, if a person falls into the sea, or if there are people waiting to be rescued on the sea surface, it is necessary to urgently send a life-saving transportation tool to the sea surface in time to rescue the people on the sea surface. Among them, the inflatable boat is a commonly used life-saving transportation tool. In the non-inflated state, multiple inflatable boats can be folded and stacked in the ship's cabin, so that more inflatable boats can be stored in a smaller cabin space. By filling the boat body with gas, it can be put into normal use, which is convenient to use. Therefore, inflatable boats are widely used.

[0003] At present, generally, a foot-operated air pump or an electric air pump is used to inflate the boat body of the inflatable boat, and then the inflated inflatable boat is thrown into the sea for use. Inflating with a foot-operated air pump is relatively slow, delaying the rescue time. And if the operation is improper or the stepping force is uneven, it will affect the inflation effect and even damage the air pump or the boat body; the inflation of the electric air pump is relatively fast, but it also needs to inflate the boat body of the inflatable boat first. Compared with the urgency of the sea rescue time, the inflation time is also relatively long. If the boat body of the inflatable boat can be inflated while the inflatable boat is being thrown into the sea, the time can be greatly shortened and the rescue efficiency can be improved. For existing inflatable boats, an electric air pump is placed in the electronic cabin of the inflatable boat, which requires that the electronic cabin has excellent water tightness and at the same time has an air intake function, resulting in a great reduction in the water tightness and inflation efficiency of the lifeboat. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-pressure and rapid inflation system for inflatable boats and an inflatable boat, so as to rapidly inflate the boat body of the inflatable boat while the inflatable boat is being thrown into the sea.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0022] The beneficial effects of the present utility model are as follows:

[0023] The utility model provides a high-pressure and rapid inflation system for an inflatable boat. When it is applied to the inflatable boat, during the process of throwing the inflatable boat into the sea, the cut-off valve is triggered to open the first air supply pipeline at the same time, and the high-pressure gas in the high-pressure gas cylinder is instantaneously released.

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] Combined with Figures 1 to 3 As shown, the utility model provides a high-pressure and rapid inflation system for an inflatable boat, including a flow dividing valve 1, a high-pressure gas cylinder 21, a first air supply pipeline 31, an air filling pipeline 4, a cut-off valve 5, a check valve 6, etc.

[0030] The flow dividing valve 1 is provided with a first air inlet interface 11, and the flow dividing valve 1 is provided with four air outlet interfaces.

[0031] The high-pressure gas cylinder 21 is filled with high-pressure gas, where the high-pressure gas is a mixed gas of carbon dioxide and nitrogen. Inside the high-pressure gas cylinder 21, carbon dioxide is in a liquid state. When the stop valve 5 is opened, the liquid carbon dioxide can instantly vaporize and release a large amount of gas into the charging pipeline 4, and then be diverted to the four independent air chambers 91 of the hull 9 of the inflatable boat, and the inflatable boat is quickly inflated and floats on the water surface. The role of nitrogen is that when the ambient temperature is below -30°C, the pressure of the high-pressure steel cylinder filled with carbon dioxide decreases and some carbon dioxide vaporizes, causing "snowflake"-like substances to appear at the mouth of the high-pressure gas cylinder 21, resulting in slow inflation. Nitrogen can break open the "snowflake"-like substances in a low-temperature environment to improve the inflation efficiency and meet the requirements of the inflatable boat for the inflation time.

[0032] The gas supply end of the high-pressure gas cylinder 21 is connected to the first air intake interface 11 of the flow control valve 1 through the first gas supply pipeline 31, and each air outlet interface is connected to one end of the charging pipeline 4, and the other end of the charging pipeline 4 is used to connect to the hull 9 of the inflatable boat.

[0033] A stop valve 5 is provided on the first gas supply pipeline 31, and the stop valve 5 is used to open or cut off the first gas supply pipeline 31. One end of the pull rope 7 is connected to the trigger end of the stop valve 5, and an external force pulls the other end of the pull rope 7 to drive the stop valve 5 to open the first gas supply pipeline. When the inflatable boat is thrown from the ship to the sea surface, the pull rope 7 is connected to an object on the ship (such as the bow rope). During the process of the inflatable boat descending from the ship to the sea surface, the trigger end of the stop valve 5 is driven to act through the pull rope 7, driving the stop valve 5 to open the first gas supply pipeline, and then the high-pressure gas in the high-pressure gas cylinder 21 quickly inflates the hull 9 of the inflatable boat.

[0034] A one-way valve 6 is provided on the charging pipeline 4, and the one-way valve 6 conducts unidirectionally from one end to the other end of the charging pipeline 4 to prevent the gas in the hull 9 from flowing back.

[0035] The pressure transmitter 8 is connected to the flow control valve 1, and the sensing end of the pressure transmitter 8 is used to monitor the gas pressure at the flow control valve 1 to monitor in real time whether the gas pressure in the hull 9 is lower than the set value. The flow control valve 1 is also provided with a second air intake interface 12, and the gas supply end of the electric air replenishing pump 22 is connected to the second air intake interface 12 of the flow control valve 1 through the second gas supply pipeline 32. The control unit is arranged inside the hull 9, and the control unit is respectively connected to the control ends of the pressure transmitter 8 and the electric air replenishing pump 22 through signal cables.

[0036] The pressure transmitter 8 monitors the gas pressure in real time. When the pressure in the air chamber 91 of the hull 9 of the inflatable boat is lower than the set value, the control unit triggers the electric air replenishing pump 22 to start and replenish air to the air chamber 91 of the hull 9 of the inflatable boat through the second gas supply pipeline 32, the second air intake interface 12 of the flow control valve 1, the air outlet interface of the flow control valve 1, and the charging pipeline 4.

[0037] The present utility model provides an inflatable boat, and the inflatable boat is provided with the above-mentioned high-pressure rapid inflation system for inflatable boats. The hull 9 of the inflatable boat is divided into four air chambers 91 (front air chamber, bottom plate air chamber, left rear air chamber, right rear air chamber), and each air chamber 91 is connected to an inflation pipeline 4.

[0038] So far, the present embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the high-pressure rapid inflation system for inflatable boats and the inflatable boat of the present utility model. For the high-pressure rapid inflation system for inflatable boats described in the present utility model, when it is applied to an inflatable boat, during the process of throwing the inflatable boat into the sea, the cut-off valve 5 is triggered to open the first air supply pipeline 31 at the same time, and the high-pressure gas in the high-pressure gas cylinder is instantaneously released, and is transported to the hull 9 of the inflatable boat through the first air supply pipeline 31, the first air inlet interface 11 of the flow dividing valve 1, the air outlet interface of the flow dividing valve 1 and the inflation pipeline 4, so that the four air chambers 91 of the hull 9 of the inflatable boat can be quickly filled with gas, thereby greatly shortening the time and improving the rescue efficiency; after the inflatable boat is launched into the water, it is basically floating on the sea surface, and the requirements for the water tightness and air inlet design of the electric air replenishing pump 22 are relatively low; the pressure transmitter 8 monitors the gas pressure in real time, and when the pressure in the air chamber 91 of the hull 9 of the inflatable boat is lower than the set value, the control unit triggers the electric air replenishing pump 22 to start, and the electric air replenishing pump 22 replenishes air to the air chamber 91 of the hull 9 of the inflatable boat through the second air supply pipeline 32, the second air inlet interface 12 of the flow dividing valve 1, the air outlet interface of the flow dividing valve 1 and the inflation pipeline 4.
