In order to improve the water outlet height of the antenna, an important way in the design of the current underwater vehicle product is to add an air bag device, air is pumped into an air bag from an air chamber to expand the air bag, a valve is opened after communication is finished, the air returns to the air chamber, and the air bag contracts.
The gas source required for the expansion of the air bag depends on the air chamber, so that the modularization of the air bag structure is difficult to realize and the air bag structure must be used together with the air chamber. The use of an air bag in conjunction with an air chamber generally requires piping to connect the air bag to the air chamber and associated equipment to control the air to and from the air bag and the air chamber, such as air pumps, air valves, etc., resulting in a complex system.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an independent air bag device for an underwater vehicle, which has a simple structure and can independently realize the expansion and contraction functions of an air bag without depending on an air chamber.
In order to achieve the above object, the present invention provides an independent airbag apparatus for an underwater vehicle, comprising an airbag, a liquid tank, and a heater, the airbag being in communication with the liquid tank, the liquid tank being loaded with a low boiling point liquid, the heater being mounted on the liquid tank and capable of heating the low boiling point liquid.
In a preferred embodiment of the present invention, the boiling point of the low boiling point liquid is 30 to 40 degrees.
In a preferred embodiment of the present invention, the low-boiling liquid is diethyl ether, pentane or dichloromethane.
As a preferable scheme of the utility model, the independent airbag device for the underwater vehicle further comprises a protective cover, the protective cover is of a hollow structure and is arranged at the tail end of the underwater vehicle, and the airbag is arranged in the protective cover.
In a preferred embodiment of the present invention, the protective cover has a tapered shape.
Compared with the prior art, the independent air bag device for the underwater vehicle has the beneficial effects that:
when the underwater vehicle works, the heater is used for heating the low-boiling-point liquid in the liquid cabin, the low-boiling-point liquid is vaporized, and the air bag is expanded, so that the buoyancy of the underwater vehicle is increased; on the contrary, the air bag dissipates heat and cools, the low-boiling-point substance liquefies, the air bag contracts, and the buoyancy of the underwater vehicle is reduced. Therefore, the independent air bag device can independently realize the expansion and contraction functions of the air bag without depending on the air chamber, and the configuration of an underwater vehicle system is greatly simplified.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 and 2, a self-contained airbag apparatus for underwater vehicles according to a preferred embodiment of the present invention includes an airbag 1, a liquid tank 2, and a heater 3, wherein the airbag 1 is in communication with the liquid tank 2, the liquid tank 2 is loaded with a low boiling point liquid 4, and the heater 3 is mounted on the liquid tank 2 and is capable of heating the low boiling point liquid 4.
When the underwater vehicle works, the heater 3 is used for heating the low-boiling-point liquid 4 in the liquid tank 2 and vaporizing the low-boiling-point liquid, and the air bag 1 is expanded, so that the buoyancy of the underwater vehicle is increased; on the contrary, the air bag 1 dissipates heat and cools, the low-boiling-point substance liquefies, the air bag 1 contracts, and the buoyancy of the underwater vehicle is reduced. Therefore, the independent air bag 1 device can independently realize the expansion and contraction functions of the air bag 1 without depending on an air chamber, and the configuration of an underwater vehicle system is greatly simplified.
Illustratively, the boiling point of the low-boiling-point liquid 4 is 30-40 degrees, and the low-boiling-point liquid can reach the boiling point by being heated slightly, so that the gasification efficiency is improved. Moreover, the volume of the low boiling point liquid 4 is increased by about 1000 times from liquid to gas, and a small amount of liquid can meet the requirement. In this embodiment, the low-boiling liquid 4 is preferably diethyl ether, pentane or dichloromethane.
Illustratively, the independent gasbag 1 device that underwater vehicle used still includes to safety cover 5, safety cover 5 is hollow out construction and sets up in the tail end of underwater vehicle, gasbag 1 set up in the safety cover 5. This safety cover 5 is used for protecting gasbag 1, avoids receiving external tractive and wearing and tearing, and it is internal to intercept great object entering cover simultaneously, guarantees that gasbag 1's inflation volume satisfies the demand.
Illustratively, the protective cover 5 is in a diversion cone shape, so as to avoid increasing water resistance after the air bag 1 is expanded, and guarantee the gliding capability of the underwater vehicle.
