Description

Technical Field

[0001] The invention relates to the technical field of inflatable boats, in particular to a method for quickly inflating an inflatable boat. Background Art

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

[0003] At present, the hull of an inflatable boat is generally inflated by a foot-operated air pump or an electric air pump, and then the inflated inflatable boat is thrown into the sea for use. The foot-operated air pump inflates relatively slowly, which delays the rescue opportunity. If the operation is improper or the pedaling force is uneven, it will affect the inflation effect and even damage the air pump or the hull. The electric air pump inflates relatively quickly, but it also needs to inflate the hull of the inflatable boat first. Compared with the urgency of the time for maritime rescue, the inflation time is also relatively long. If the hull of the inflatable boat can be inflated while the inflatable boat is thrown into the sea, the time can be greatly shortened and the rescue efficiency can be improved. In existing inflatable boats, the electric air pump is placed in the electronic compartment of the inflatable boat, which requires the electronic compartment to have excellent water tightness and air intake function, which greatly reduces the water tightness and inflation efficiency of the lifeboat.

[0022] In order to make the purpose, technical scheme and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. Certain embodiments of the present invention will be described more comprehensively with reference to the accompanying drawings, in which some but not all embodiments will be shown. In fact, the various embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments described herein; rather, these embodiments are provided so that the present invention meets applicable legal requirements.

[0023] In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "back" and the like indicate directions or positional relationships based on directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] Please refer to Figures 1 to 4 As shown, a method for quickly inflating an inflatable boat is provided, wherein the inflatable boat is provided with a high-pressure quick inflation system, and the high-pressure quick inflation system includes a diverter valve 1, a high-pressure gas cylinder 21, a first gas supply pipeline 31, an inflation pipeline 4, a stop valve 5 and a one-way valve 6, etc.

[0025] The diverter valve 1 is provided with a first air inlet interface 11 , and the diverter valve 1 is provided with four air outlet interfaces.

[0026] The high-pressure gas cylinder 21 is filled with high-pressure gas, wherein the high-pressure gas is a mixture of carbon dioxide and nitrogen. The carbon dioxide in the high-pressure gas cylinder 21 is in liquid form. When the stop valve 5 is opened, the liquid carbon dioxide can be instantly gasified and release a large amount of gas into the inflation pipeline 4, and then diverted to the four independent air chambers 91 of the hull 9, 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 is reduced and part of the carbon dioxide is gasified, causing "snow flakes"-like substances to appear at the mouth of the high-pressure gas cylinder 21, resulting in slow inflation. Nitrogen can break through the "snow flakes"-like substances in a low-temperature environment to improve the inflation efficiency and meet the requirements of the inflatable boat for inflation time.

[0027] The gas supply end of the high-pressure gas cylinder 21 is connected to the first gas inlet interface 11 of the diverter valve 1 through the first gas supply pipeline 31, and each gas outlet interface is connected to one end of the inflation pipeline 4, and the other end of the inflation pipeline 4 is used to connect to the air chamber 91 of the hull 9 of the inflatable boat.

[0028] The first gas supply pipeline 31 is provided with a stop valve 5, which is used to open or shut 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, the pull rope 7 is connected to an object on the ship (such as a bow cable). When the inflatable boat is lowered from the ship to the sea, the pull rope 7 drives the trigger end of the stop valve 5 to move, 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.

[0029] A one-way valve 6 is provided on the inflation pipeline 4 , and the one-way valve 6 is unidirectionally conducted from one end of the inflation pipeline 4 to the other end to prevent the gas in the hull 9 from flowing back.

[0030] The pressure transmitter 8 is connected to the diverter valve 1, and the sensing end of the pressure transmitter 8 is used to monitor the gas pressure at the diverter valve 1, so as to monitor in real time whether the gas pressure in the air chamber 91 of the hull 9 is lower than the set value. The diverter valve 1 is also provided with a second air inlet interface 12, and the air supply end of the electric air supply pump 22 is connected to the second air inlet interface 12 of the diverter valve 1 through the second air supply pipeline 32. The control unit is arranged in the hull 9, and the control unit is connected to the pressure transmitter 8 and the control end of the electric air supply pump 22 through signal cables.

[0031] 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 supply pump 22 to start replenishing 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 diverter valve 1, the air outlet interface of the diverter valve 1 and the inflation pipeline 4.

[0032] 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), each air chamber 91 is connected to an inflation pipeline 4 to inflate the four air chambers 91 synchronously, further improving the inflation efficiency of the hull 9.

[0033] The method for rapidly inflating an inflatable boat of the present invention comprises the following steps:

[0034] S1. The inflatable boat is thrown onto the sea surface, triggering the high-pressure gas cylinder 21 to instantly inflate

[0035] When the inflatable boat is thrown to the sea, the stop valve 5 is triggered to open the first air supply pipeline 31, and the high-pressure gas in the high-pressure gas cylinder 21 is released instantly and transported to the air chamber 91 of the hull 9 of the inflatable boat through the first air supply pipeline 31, the first air inlet interface 11 of the diverter valve 1, the air outlet interface of the diverter valve 1 and the inflation pipeline 4;

[0036] The process of “triggering the stop valve 5 to open the first gas supply pipeline 31” is as follows:

[0037] When the inflatable boat is thrown onto the sea, the pull rope 7 is connected to the object on the ship. When the inflatable boat is lowered from the ship to the sea, the pull rope 7 drives the trigger end of the stop valve 5 to move, driving the stop valve 5 to open the first air supply pipeline 31. In this way, the stop valve 5 can open the first air supply pipeline 31 while the inflatable boat is thrown onto the sea, further shortening the inflation time and improving the rescue efficiency.

[0038] S2, electric air supply pump 22 air supply

[0039] 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 supply pump 22 to start replenishing 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 diverter valve 1, the air outlet interface of the diverter valve 1 and the inflation pipeline 4.

Based on the above description, those skilled in the art should have a clear understanding of the method for rapidly inflating an inflatable boat of the present invention.
