Description
Technical Field
The invention relates to the field of underwater navigation, in particular to a device for generating buoyancy for a submersible vehicle and a using method thereof.
Background
With the development of world science and technology, mankind has looked at more distant deep space and deeper sea. Exploring the unknown sea bottom requires "special" equipment as does vast deep space, where the submersible is a powerful equipment to explore the sea, and the choice of buoyancy and buoyancy materials that the submersible is equipped with is one of its key technologies.
The buoyancy device is a component arranged on the submersible for balancing the weight of equipment and structures of the submersible, and the overall density of the buoyancy device is less than that of seawater.
The buoyancy device of the "riejastet" submersible which first reached the deepest point of the maryland's gully in 1960, 1-23, is an oil reservoir to which a spherical steel pod is fixed. The oil reservoir is filled with gasoline lighter than water to enable the vehicle to float out of the water if necessary.
Later submersibles have abandoned the use of flammable gasoline to provide buoyancy. Instead, a solid buoyancy material, referred to as a buoyancy material for short, is used. Modern buoyancy materials include rigid polyurethane foam, glass bead composite foam and the like. In general, the water pressure resistance rating of a buoyant material is proportional to its own density in a positive manner. At depths of 0 to 7000 meters, the density advantage of buoyant materials is irreplaceable. Even if the water depth is 7000 m, the buoyancy material can be controlled to be thin and thin according to the density of the buoyancy material is only 0.60g/cm for carrying out the thin and long-distance cultivation. Static buoyancy of not less than 400kg can be generated per cubic meter of buoyancy material. However, for 11000m (full sea depth), the method requires 0.69 g/cm to 0.79g/cm for carrying out high-speed cultivation, even some buoyancy materials have a density as high as 0.89g/cm for ensuring the structural strength and the use times3. Compared with the method of carrying out thin film fruit-thin film. And the solid buoyant material is a solid material, so that a certain water absorption rate (usually about 1% -3%) exists. The presence of water absorption means that a loss of buoyancy occurs. And the repeated 'pressurization and depressurization' process of the water outlet and the water inlet easily causes the solid buoyancy material to crack and become powder.
Therefore, a new buoyancy device that is convenient to use and reusable is needed.

Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which specific embodiments of the invention are shown. Various advantages and benefits of the present invention will become apparent to those of ordinary skill in the art upon reading the following detailed description of the specific embodiments. It should be understood, however, that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. The following embodiments are provided so that the invention may be more fully understood. Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by those of skill in the art to which this application belongs.
A submersible vehicle 1 employing the buoyancy device of the present invention is shown in perspective view in figures 1 and 2 and comprises a main body portion and the buoyancy device. Wherein the main body portion mainly comprises a main compartment 101 and an electronic compartment 105 combined. The main deck 101 may be a manned or unmanned observation deck or the like.
The buoyancy device comprises: the buoyancy module 102 is attached to the main body of the submersible, the top check valve 103 is located at the top of the buoyancy module 102, the pressure compensator 104 is located on the wall of the buoyancy module 102, the bottom check valve 106 is located at the bottom of the buoyancy module 102, the container 2 is used for storing liquid buoyancy materials, the liquid pipeline 201 is connected with the container 2 and the bottom check valve 106, the pump 3 is connected with the first gas pipeline 301 which is connected with the pump 3 and the top check valve 103, and the second gas pipeline 302 is connected with the pump 3 and the container 2.
The pressure compensator 104 may be a flexible membrane. The device is used for regulating and controlling the pressure difference between the inside and the outside of the buoyancy cabin in real time to achieve the pressure balance between the inside and the outside of the cabin.
The vessel 2 has stored therein a liquid buoyant material which, in use, is injected from the vessel 2 into the buoyancy chamber 102. The liquid buoyancy material is a hexane mixed solution added with the following components: glycerol (glycerin) with 3-5% of total volume capacity, alcohol solution (alcohol content is 71%) with 5% of volume capacity, and MgSO 2-3 g per 1000 ml4。
Hexane, of the formula C6H14, is an alkane having 6 carbon atoms and is the five isomers of n-hexane, 2-methylpentane, 3-methylpentane, 2, 3-dimethylbutane and 2, 2-dimethylbutane. At normal temperature, hexane is liquid, the boiling point is 68-70 ℃, and the density is as follows: and (5) carrying out high-speed harvest at 0.672 g/cm. Hexane is a highly flammable liquid, but a hexane mixture solution to which the above components are added is not readily flammable.
The shapes of the main compartment 101, the buoyancy compartment 102 and the electronic compartment 105 are only schematically shown. It will be appreciated by those skilled in the art that other suitable shapes are also contemplated. The joint of the buoyancy cabin, the main cabin and the electronic cabin can be met.
Hexane is a toxic and volatile liquid and is corrosive to plastic products, so the buoyancy chamber is designed into a double-layer structure, and the outer layer adopts glass fiber reinforced plastics or carbon fibers; the inner layer can be made of metal, preferably aluminum alloy, titanium alloy, stainless steel and other metal materials. The thickness of the inner layer can meet the basic strength. The design can effectively ensure that the hexane cannot volatilize and reduce the toxic hazard of the hexane.
Fig. 3 shows a flow chart of the injection of the hexane mixture solution into the buoyancy chamber. The container 2 stores the hexane mixture solution, and when the submerging task is executed, the pump 3 pumps gas through the gas pipeline 302, so that the hexane mixture solution in the container 2 is pressed into the liquid pipeline 201, and then the hexane mixture solution is further pressed into the buoyancy chamber 102, and the injection process of the hexane mixture solution is completed.
Figure 4 shows a flow chart for discharging the hexane mixed solution from the buoyancy chamber. During recovery, gas is pumped into the buoyancy chamber 102 through the gas line 301 by the pump 3, and the gas presses the hexane mixture solution in the buoyancy chamber 102 to flow back to the liquid line 201, and finally the hexane mixture solution is recovered into the container 2.
Wherein, two electric control one- way valves 103 and 106 are arranged on the buoyancy chamber 102, and when the hexane mixed solution is injected, the one-way valve 106 of the liquid pipeline 201 communicated with hexane is opened inwards, so that the hexane mixed solution can only flow inwards; meanwhile, the check valve 103 communicated with the gas pipeline 301 is opened outwards, and the gas can be discharged outwards only.
The liquid pipeline 201 and the gas pipelines 301 and 302 are preferably transparent pipelines so as to observe and judge the volume change of the hexane mixed solution in the buoyancy chamber 102, when the hexane mixed solution is injected into the buoyancy chamber 102, if the hexane mixed solution appears in the gas pipeline 301 between the pump 3 and the electrically controlled one-way valve 103, the buoyancy chamber 102 is considered to be filled with the hexane mixed solution, and at this time, the pump 3 is turned off, and the injection is completed. On the contrary, during the discharging of the hexane mixture solution, if air appears in the liquid line 201 between the container 2 and the one-way valve 106, it indicates that the discharging of the hexane mixture solution in the buoyancy chamber 102 is completed, and at this time, the pump 3 is turned off, and the recovery of the hexane mixture solution is completed.
In the process of filling the hexane mixed solution, the sealing performance of the connecting pipeline is strictly ensured, and the hexane mixed solution is strictly filled according to the filling requirement to prevent leakage.
The invention adopts hexane mixed solution as liquid buoyancy material to be injected into the buoyancy chamber, and has the following advantages:
firstly, when the submersible is designed, a complex shape is inevitable, the traditional solid buoyancy material is influenced by a section bar and is difficult to be processed into a perfect fit shape of the submersible, but the invention adopts the liquid buoyancy material and only needs to be filled into a buoyancy chamber from a container when in use, so that the submersible is designed without considering the shape of the buoyancy material, and the submersible can be better in accordance with deep diving requirements, including the requirements of low-resistance fluid appearance, arrangement requirements of other functional components and the like. As long as the buoyancy compartment is attached to the main compartment.
Secondly, the hexane mixed solution with the formula is liquid at normal temperature and is submerged in deep sea, and the liquid can be well maintained under the condition that the temperature of the sea water is 2-4 ℃. Without the liquid being "crushed" under high pressure. As long as the seawater pressure outside the cabin is transmitted through the pressure compensator or even a layer of soft membrane, the pressure inside the liquid hexane can be kept equal to the external seawater pressure all the time. Therefore, the bulkhead of the buoyancy chamber is a pressure shell which does not need to be made into high strength. Thus greatly reducing the overall weight.
Thirdly, the traditional solid buoyancy material can be crushed into powder after being used for a plurality of times, and can not be used any more. Furthermore, solid buoyant materials are limited to processing and once formed can only be used on "dedicated" submersibles and cannot be reused. And the hexane mixed solution can be repeatedly utilized, so that the utilization rate of the material is greatly improved, and the hexane mixed solution is not limited to single equipment any more.
The traditional solid buoyancy material is formed by cutting and processing a whole block of material and is directly applied to the surface of the submersible, the problem of water absorption (the water absorption rate is about 1% -3% generally) exists under the condition of no special protection, and even if special protection is adopted, because the buoyancy material is directly contacted with seawater, the problem of water absorption to a certain degree is inevitable, and accidents are possibly caused. And the hexane mixed solution is liquid, so that the problem of water absorption does not exist.
The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present disclosure, and the present disclosure should be construed as being covered by the claims and the specification.
