Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of airships, and more particularly relates to a three-body helium-hydrogen hybrid power airship. BACKGROUND

[0002] With the implementation of the new energy strategy, the transportation and installation demands of large facilities such as wind turbines are increasing. However, areas rich in wind resources are often located in areas with weak roads and infrastructure (such as mountainous areas), and large engineering hoisting machinery is also very difficult to operate in these areas. The traditional transportation method is limited by road infrastructure, which results in a high proportion of transportation and installation costs. Although sea transportation is cost-effective, it is not suitable for inland areas. As a new type of transportation tool, airships have attracted attention due to their large carrying capacity and economic cost, and have obvious advantages in areas with imperfect infrastructure, as well as in cargo transportation, transportation and installation of oversized items, forest water supply for fire fighting, etc.

[0003] However, due to a series of accidents in history, the use of airships has been severely affected, and safety has become a key factor restricting the development of airships. In recent years, helium airships have been widely used in the fields of exploration and meteorology, and safety has been well guaranteed, but the scarcity and high price of helium have limited the use of airships.

[0004] Hydrogen, as a new energy source, has attracted widespread attention in the field of transportation. However, in order to use hydrogen in the transportation industry, it needs to go through the energy-consuming and complex step of compression, and use expensive high-pressure hydrogen storage bottles. However, airships, with their large structure and excellent load-carrying capacity, provide new possibilities for the application of hydrogen. Hydrogen can not only provide lift as a buoyancy medium in airships, but also provide energy supply for fuel cells to provide propulsion. Airships directly use hydrogen, avoiding the energy-consuming process of compression, and can store hydrogen produced by electrolysis of water in the airbag for direct use, providing both buoyancy and fuel as needed, greatly improving energy efficiency. Therefore, airships have shown high efficiency and economy in the application of hydrogen. However, how to solve the safety of hydrogen used in airships is a major problem that airships face.

[0005] In order to ensure flight safety, modern airships generally use helium as a lifting gas. However, due to the limited resources of helium, and the traditional airship needs to increase or decrease the amount of helium to control the lift, resulting in high operating costs. But helium as an inert gas, mixed with hydrogen can reduce the proportion of hydrogen, greatly reducing the risk of single use of hydrogen. And helium as an inert gas does not react with fuel cells, can be recycled and reused, and does not have to be discharged and wasted. Helium not only provides lift as a gas, but also as an inert gas to dilute hydrogen to ensure safety, and can also be used as a fuel cell carrier gas.

[0006] According to the above problems and the obvious advantages of helium and hydrogen, how to provide a safe, stable and efficient three-body helium-hydrogen hybrid power airship is a problem that needs to be solved by those skilled in the art. SUMMARY

Obviously, the accompanying drawings in the following description only aim at the embodiments of the present application, and other drawings can be obtained by those skilled in the art without any creative effort on the basis of the provided drawings.

[0025] 1-pure hydrogen cabin; 2-helium-hydrogen mixed cabin; 3-battery cabin; 4-hang cabin; 5-flowing helium cabin; 6-oxygen cabin; 7-compressed helium steel cylinder; 8-operator cabin; 9-closed helium cabin; 10-airship frame; 11-electric ducted fan propulsion system; DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0027] Please refer to the accompanying drawings Figs. 1-2 The present application provides a three-body type helium-hydrogen hybrid power airship, which comprises an airship frame 10, an electric ducted fan propulsion system 11, a main gas bag area, a secondary gas bag area, a battery cabin 3 and a hang cabin 4.

[0028] The airship frame 10 adopts titanium alloy or high-strength steel material in the main force support part, adopts aviation aluminum alloy or carbon fiber support in the general force area, and adopts high-strength nylon rope in the fixed position of the main gas bag area and the secondary gas bag area.

[0029] The electric ducted fan propulsion system 11 includes a plurality of fans enclosed in a duct driven by an electric motor to generate thrust, which are evenly arranged on both sides of the top of the airship frame 10, and can assist the airship to fly. The electric motor of the electric ducted fan propulsion system 11 is electrically connected to the battery cabin 3. During the take-off stage, it can be adjusted to be vertically downward to help the airship take off quickly. After entering the level flight height, it can be rotated to the horizontal direction to propel forward or backward. By applying different thrust ratios on both sides, the airship can be turned around by applying thrust in opposite directions on the two diagonal sides. When the airship needs to achieve a short descent without releasing part of the hydrogen or helium, the thrust direction can be upward to push the airship to land downward temporarily, saving part of the hydrogen. The electric ducted fan propulsion system 11 can also be set as a wind power generation system, which can be adjusted to the windward surface when there is no power suspension to make the fan rotate to generate electricity and charge.

[0030] The airbags in the main airbag area and the auxiliary airbag area are made of a multi-layer composite anti-static material embedded with Kevlar fiber, mainly composed of polytetrafluoroethylene, polyamide and other lightweight, high-strength, weather-resistant and gas-permeable materials, and conductive metal wires. The weight, strength, weather resistance, permeability resistance, anti-static effect and cost-effectiveness of the material are considered comprehensively.

[0031] The main airbag area is arranged in the middle of the airship frame 10 and includes a sealed helium cabin 9 for providing the main lift for the airship. The sealed helium cabin 9 is arranged on both sides of the airship frame 10, and the volume of helium filled therein provides a buoyancy equal to the total weight of the airship and the ballast water. The inside of the sealed helium cabin 9 is also provided with a compressed helium cylinder 7. Although the helium cabin is sealed for storage and does not emit during the entire life cycle of the airship, due to the molecular leakage of the material, it still needs to be periodically supplemented with helium to maintain and ensure that the sealed helium cabin 9 is full of helium, which can also provide additional lift in emergency situations. The compressed helium cylinder 7 needs to be replaced regularly.

[0032] The auxiliary airbag area is arranged at the upper part of the airship frame 10 to provide gas fuel for the battery cabin 3 and also provide lift for the airship, including a pure hydrogen cabin 1, a helium-hydrogen mixed cabin 2, a flowing helium cabin 5 and an oxygen cabin 6. The pure hydrogen cabin 1 is arranged at the top of the airship and the front head position of the airship. Such arrangement makes the hydrogen mainly located in the upper and front areas of the airship, so even if leakage occurs, due to its light weight, it can mainly leak upward, having less impact on the lower or rear.

[0033] The helium-hydrogen gas mixing cabin 2 is filled with mixed gas of helium and hydrogen. Helium, as an inert gas, can reduce the proportion of hydrogen after mixing with hydrogen, greatly reducing the risk of using hydrogen alone. The oxygen cabin 6 is used to deliver oxidant to the hydrogen fuel cell to participate in the hydrogen fuel cell reaction. The flowing helium cabin 5 is arranged between the helium-hydrogen gas mixing cabin 2 and the oxygen cabin 6, which is used to isolate the helium-hydrogen gas mixing cabin 2 and the oxygen cabin 6, so as to avoid the influence of the oxygen cabin 6 when the hydrogen leaks or burns.

[0034] The battery cabin 3 includes a hydrogen fuel cell, a power battery, a photovoltaic hydrogen production system and a pure water tank.

[0035] The battery cabin 3 is installed in the middle of the airship frame 10 along the longitudinal direction of the airship body through a slide rail and a roller. The slide rail is open at both ends, which can be removed when the airship is in danger. When there is no risk, the roller of the battery cabin 3 is slowly translated by a motor drive, and a locking structure is further arranged on the roller to lock the position of the battery cabin 3. The locking structure can realize the adjustment of the gravity distribution of the airship body, and keep the gravity distribution balance of the whole airship when different gases are filled in different cabin sections and different cargos are carried. When there is a risk, the connection line bundle and the pipeline outside the battery cabin 3 are cut off, the slide rail locking structure is released, and the battery cabin 3 is separated from the front end or the rear end, so as to reduce the self-weight of the airship, obtain the buoyancy, and ensure the safe and slow descent of the main body. Due to the existence of the one-way valve on the pipeline, various gases will not leak. The battery cabin 3 is further provided with a parachute system and an altimeter, which can be automatically opened when the altitude is lower than a certain height after the system is activated, so as to facilitate the recovery of the system.

[0036] The reaction front end of the hydrogen fuel cell is connected with the helium-hydrogen gas mixing cabin 2, the pure hydrogen cabin 1 at the head and the oxygen cabin 6 through a pipeline with a one-way valve. The hydrogen in the helium-hydrogen gas mixing cabin 2 or the pure hydrogen in the pure hydrogen cabin 1 at the head is used as the fuel of the hydrogen fuel cell, and the oxygen is used as the oxidant to participate in the electrochemical reaction, and the reaction produces water and electric energy. Helium and hydrogen enter the reaction chamber together during the reaction, and helium, as an inert gas, does not participate in the hydrogen fuel cell reaction. The reaction rear end of the hydrogen fuel cell is connected with the helium-hydrogen gas mixing cabin 2 and the flowing helium cabin 5 through a pipeline with a one-way valve and a multi-way valve. The reacted helium is filled back to the helium-hydrogen gas mixing cabin 2 or introduced into the flowing helium cabin 5. The reaction rear end of the hydrogen fuel cell is also connected with the closed helium cabin 9 through a pipeline with a one-way valve and a multi-way valve, and the reacted helium is introduced into the closed helium cabin 9 for supplement. The proportion of the helium-hydrogen gas mixing cabin 2 / flowing helium cabin 5 at the top can be dynamically adjusted by the flow direction of helium, so as to realize the precise control of the size and distribution area of the buoyancy. The multi-way valve can be switched to connect each pipeline, and different gas flow paths can be quickly switched to connect the hydrogen fuel cell in the required manner.

[0037] The hydrogen fuel cell has two working states: when the hydrogen fuel cell is provided with mixed gas from the helium-hydrogen gas mixing cabin 2 to react as a power battery (which can be a lithium ion battery) to store energy or directly power the airship, it is in the slow reaction charging / discharging stage, which can be operated when the airship is floating or cruising at an economic speed; when the hydrogen fuel cell is provided with pure hydrogen gas from the pure hydrogen gas cabin 1 located at the head to participate in the reaction, it is in the fast reaction charging / discharging stage, which can be operated when the power battery pack is discharged and needs to sail at full speed or needs to be quickly charged, and the hydrogen fuel cell stops working after the power battery is fully charged. The two working states of the hydrogen fuel cell can be flexibly switched to generate electric energy to charge the power battery or directly provide power support for the airship; the water generated by the hydrogen fuel cell is introduced into the pure water tank for the photovoltaic hydrogen production system. Part of the water in the pure water tank comes from the hydrogen fuel cell, and part comes from external supplement.

[0038] In the slow reaction charging / discharging stage, the hydrogen-helium mixed gas is used for reaction, and pure oxygen in the oxygen cabin 6 can be used for reaction, and helium can be directly recycled; when the oxygen in the oxygen cabin 6 is exhausted, air can also be used to continue the reaction of the hydrogen fuel cell. At this time, the products generated after the mixed gas reaction will include water, nitrogen, helium and a small amount of carbon dioxide and other gases. Since the helium molecule is small, it can easily penetrate through the molecular film material (such as metal organic framework (MOF) film: ZIF-8_I-43m film, or polyimide (PI) material), a molecular film can be set at the inlet of the pipeline leading to the helium cabin to separate and recycle helium, while nitrogen and carbon dioxide are discharged into the atmosphere. However, such separation requires high gas pressure and high cost, so it is not used as the main way.

[0039] In the fast reaction charging / discharging stage, pure hydrogen is used for reaction, and air can be directly used for reaction at this time, and the hydrogen fuel cell mainly discharges nitrogen and water after reaction, and no gas is recycled in this stage. Nitrogen is directly discharged into the atmosphere.

[0040] Therefore, in the charging stage and the cruising stage which occupy a large amount of time, the hydrogen-helium mixed gas cabin is mainly relied on to provide the source of reaction gas, and oxygen participates in the reaction. Helium is recycled in this stage.

[0041] When it is necessary to descend or the oxygen is exhausted, the pure hydrogen gas cabin is mainly relied on to provide the source of reaction gas and directly reacts with air. No gas is recycled in this stage.

[0042] The hydrogen fuel cell or the city power supply is used to charge the power battery pack and to supplement the hydrogen tank during the take-off preparation stage, the hydrogen-helium mixed gas tank provides the main reaction gas source, the recovered helium can provide sufficient lift for the helium area on both sides, and the cable and ballast water can be released to achieve the lift, the power battery is mainly used for the flight within the range, and the hydrogen-helium mixed gas tank and the hydrogen fuel cell are used to provide additional endurance when the range is exceeded, and the photovoltaic system can obtain a certain supplement at high altitude.

[0043] The photovoltaic hydrogen production system comprises an electrolytic tank and a photovoltaic power generation unit; the structure of the photovoltaic power generation unit is the same as that of the prior art, and will not be described here; the solar photovoltaic panel assembly of the photovoltaic power generation unit is installed above and on both sides of the closed helium tank 9, and the relatively hard surface can provide a certain protection for the air bag to a certain extent. The photovoltaic power generation unit is used to power the electrolytic tank; the inlet end of the electrolytic tank is communicated with the pure water tank, the cathode side of the outlet end is communicated with the helium-hydrogen mixed tank 2, the pure hydrogen tank 1 located at the head through the pipeline with a one-way valve and a multi-way valve, and the anode side of the outlet end leads to the oxygen tank 6. When the airship hovers in the air and does not consume a large amount of energy, the photovoltaic power generation unit can generate electric energy, and the electrolytic water produces hydrogen and oxygen, which continuously provides supplemental energy. The electrolytic tank electrolyzes water to produce hydrogen by using the power supply of the photovoltaic power generation unit, the generated hydrogen first fills the helium-hydrogen mixed tank 2, and then continues to fill the pure hydrogen tank 1 located at the head and the top, the generated oxygen fills the oxygen tank 6, and the consumption of the hydrogen fuel cell is supplemented.

[0044] The gondola 4 is arranged at the lower part of the airship frame 10 and has a certain energy absorption and collapse capacity. The gondola 4 can be internally provided with a personnel cabin or a cargo cabin, which is used for transporting personnel or large mechanical equipment such as a wind turbine, and can also store ballast water. An operator cabin 8 is further arranged above the gondola 4. Landing rollers and supports are arranged on both sides of the gondola 4, or air cushion devices are arranged.

[0045] When hydrogen leakage or fire risk occurs, since the risk position is located at the upper part of the airship, and the closed helium tank 9 on both sides of the airship can provide a buoyancy equivalent to the self-weight of the airship, the gondola 4 can ensure that it has sufficient buoyancy by discarding cargo or reducing the weight of ballast water, and ensure the safety of the main body structure.

[0046] The airship of the application has excellent transportation capacity, can easily accommodate the tower and blades of a wind turbine, and can directly fly to the installation site without being affected by the complex road conditions in mountainous areas when performing a transportation task.

[0047] When installing wind turbines in mountainous areas, the airship can fly to the installation point directly above and hover, releasing four fixed ropes in different directions. The fixed piles and traction machines buried in advance around the installation point will be used to receive these ropes. By winding the fixed ropes on the traction machine, the airship can be stably fixed. Under the coordinated operation of ground personnel, the traction rope guides the airship to slowly descend and hover in the ideal position, keeping stable. Then, through hoisting operations, the tower and blades are installed in place. In addition, large airships also have the ability to transport heavy engineering machinery such as excavators. This innovative transportation and installation method will greatly reduce the transportation and installation cost of wind turbines, while simplifying the installation process and reducing the construction difficulty.
