Description

Technical Field

[0001] The invention belongs to the technical field of airships, and more specifically relates to a three-body helium-hydrogen hybrid airship. Background Art

[0002] With the implementation of the new energy strategy, the demand for transportation and installation of large facilities such as wind turbines is increasing. However, areas with rich wind resources are often located in areas with weak roads and infrastructure (such as mountainous areas). Large-scale engineering lifting machinery is also very difficult to construct in these areas. Traditional transportation methods are limited by road infrastructure, which leads to a very high proportion of transportation and installation costs. Although sea transportation is low-cost, it is not applicable in inland areas. As an emerging means of transportation, airships have attracted much attention for their huge carrying capacity and economical cost. They have obvious advantages, especially in areas with imperfect infrastructure. They can also play an advantage in freight, transportation and installation of oversized items, forest water collection and firefighting, etc.

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

[0004] As an emerging energy source, hydrogen has attracted widespread attention in the field of transportation. However, in order to use hydrogen in the transportation industry, it is necessary to go through the energy-consuming and complex step of compression, and use expensive high-pressure hydrogen storage and transportation bottles. However, airships, with their huge structure and excellent load-bearing capacity, provide new possibilities for the application of hydrogen. Hydrogen can not only provide lift as a buoyancy medium in airships, but also be used as an energy supply to provide propulsion for fuel cells. The direct use of hydrogen by airships avoids energy-consuming processes such as compression. The hydrogen produced by electrolysis of water can be directly stored in the airbag and can be used directly, which not only provides buoyancy for itself, but also can be used as fuel on demand, greatly improving the efficiency of energy use. Therefore, airships have shown extremely high efficiency and economy in the application of hydrogen. However, how to solve the safety of using hydrogen on airships is the main problem facing airships.

[0005] In order to ensure flight safety, modern airships generally use helium as a buoyancy gas. However, due to the limited helium resources and the need to increase or decrease the amount of helium to control the rise and fall of traditional airships, the operating costs are relatively high. However, helium, as an inert gas, can reduce the proportion of hydrogen when mixed with hydrogen, greatly reducing the risk of using hydrogen alone. Moreover, helium, as an inert gas, does not react with fuel cells and can be recycled and reused without wasteful emissions. Helium is used as a gas to provide buoyancy, as an inert gas to dilute hydrogen to ensure safety, and can also be used as a carrier gas for fuel cells.

[0006] In view of the above-mentioned problems and the obvious advantages of helium and hydrogen, how to provide a safe, stable and efficient three-body helium-hydrogen hybrid airship is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0007] In view of this, the present invention provides a three-body helium-hydrogen hybrid airship, which adopts the following technical solution:

[0008] A three-body helium-hydrogen hybrid airship comprises an airship frame, an electric ducted fan propulsion system, a main airbag area, an auxiliary airbag area, a battery compartment and a pod; the electric ducted fan propulsion system is arranged on both sides of the top of the airship frame to assist the airship in flight; the electric ducted fan propulsion system is electrically connected to the battery compartment; the main airbag area is arranged in the middle of the airship frame, comprising a closed helium compartment for providing main lift for the airship; the closed helium compartment is arranged on both sides of the airship frame; the auxiliary airbag area is arranged in the upper part of the airship frame to provide gas fuel for the battery compartment and also to provide lift for the airship; the battery compartment is slidably arranged in the middle of the airship frame to provide power for the airship and adjust the center of gravity distribution of the airship by sliding; the pod is arranged in the lower part of the airship frame.

[0009] Furthermore, the electric ducted fan propulsion system includes a plurality of fans enclosed in the duct, which are driven by a motor to generate thrust; the fans are evenly arranged on both sides of the top of the airship frame and are rotatably connected to the airship frame.

[0010] Furthermore, a compressed helium cylinder is provided inside the closed helium cabin for replenishing helium into the closed helium cabin or providing additional lift in an emergency.

[0011] Furthermore, the battery compartment is installed on the airship frame along the longitudinal direction of the hull through slide rails and rollers; the rollers of the battery compartment are driven by a motor to translate on the slide rails to adjust the center of gravity; a locking structure is also provided on the rollers to lock the position of the battery compartment; the slide rails are open at both ends to release the battery compartment in an emergency to reduce weight.

[0012] Furthermore, the auxiliary airbag area includes a pure hydrogen cabin, a helium-hydrogen mixed cabin, a flowing helium cabin and an oxygen cabin; the pure hydrogen cabin is arranged on the top of the airship and at the front head position of the airship; the helium-hydrogen mixed cabin is filled with a mixed gas of helium and hydrogen, the oxygen cabin is used to transport oxidants to the hydrogen fuel cell to participate in the hydrogen fuel cell reaction, and the flowing helium cabin is arranged between the helium-hydrogen mixed cabin and the oxygen cabin to isolate the helium-hydrogen mixed cabin and the oxygen cabin.

[0013] Further, the battery cabin includes a hydrogen fuel cell, a power battery, a photovoltaic hydrogen production system and a pure water tank; the reaction front end of the hydrogen fuel cell is connected to the helium-hydrogen mixing cabin, the pure hydrogen cabin located at the head and the oxygen cabin through a pipeline with a one-way valve and a multi-way valve, and the mixed hydrogen in the helium-hydrogen mixing cabin or the pure hydrogen in the pure hydrogen cabin located at the head is used as the fuel of the hydrogen fuel cell, and oxygen is used as an oxidant to participate in the electrochemical reaction to generate water and electric energy; the reaction rear end of the hydrogen fuel cell is respectively connected to the helium-hydrogen mixing cabin, the flowing helium cabin and the closed helium cabin through pipelines with a one-way valve and a multi-way valve, and the reacted helium is filled back into the helium-hydrogen mixing cabin, passed into the flowing helium cabin or passed into the closed helium cabin; the electric energy generated by the hydrogen fuel cell is used to charge the power battery, or directly provide power support for the airship; the hydrogen fuel cell is connected to the pure water tank, and the generated water is passed into the pure water tank for supplying the photovoltaic hydrogen production system.

[0014] Furthermore, the hydrogen fuel cell has two working states: when the hydrogen fuel cell is provided with a mixed gas by a helium-hydrogen mixing chamber to react to store energy for charging the power battery or directly power the airship, it is a slow reaction charging / discharging stage; when the hydrogen fuel cell is provided with pure hydrogen by a pure hydrogen chamber located at the head to participate in the reaction, it is a fast reaction charging / discharging stage.

[0015] Furthermore, the photovoltaic hydrogen production system includes an electrolyzer and a photovoltaic power generation unit; the solar photovoltaic panel assembly of the photovoltaic power generation unit is installed above and on both sides of the closed helium cabin; the photovoltaic power generation unit is used to power the electrolyzer; the inlet end of the electrolyzer is connected to the pure water tank, and the cathode side of the outlet end is connected to the helium-hydrogen mixing cabin and the pure hydrogen cabin located at the head through a pipeline with a one-way valve and a multi-way valve, and the anode side of the outlet end leads to the oxygen cabin, and the generated hydrogen is first filled into the helium-hydrogen mixing cabin, and then continues to fill the pure hydrogen cabin located at the head, and the generated oxygen is filled into the oxygen cabin to supplement the consumption of the hydrogen fuel cell.

[0016] Furthermore, a personnel cabin or a cargo cabin is arranged inside the pod for transporting personnel or large mechanical equipment, and ballast water is also arranged; an operator cabin is also arranged above the pod; and lifting and lowering rollers and brackets are arranged on both sides of the pod, or an air cushion device is arranged.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention optimizes the structural design of the airship and sets a three-body structure, with the lower part being a personnel cabin or a cargo cabin, the middle part being a main airbag area, and the upper part being a secondary airbag area, and being provided with various air compartments and power storage compartments. The three-body design makes the entire airship more stable during flight and has better advantages when performing hoisting operations. The design of the entire system fully considers the combustion characteristics of hydrogen, so the hydrogen cabins are mainly arranged at the top and head of the airship. Such a layout means that once a leak occurs, the hydrogen will burn upwards, reducing the impact on other parts of the airship. In addition, by adopting the hydrogen-helium mixed gas technology, the addition of inert gas helium significantly reduces the risk during the use of hydrogen.

[0019] 2. The present invention utilizes the connectivity between the main airbag area, the auxiliary airbag area and the battery compartment to achieve two working modes, and uses a mixed gas as the reaction gas of the hydrogen fuel cell to improve safety while maintaining high energy efficiency. Hydrogen exists only in the form of a small amount of pure gas, and most of it exists in the form of a mixed gas with helium. The mixing ratio can avoid the explosion range of hydrogen. The use of mixed gases not only provides lift, but also reduces the risk of combustion and explosion. It can also store a large amount of hydrogen for use by hydrogen fuel cells to ensure endurance and ensure that expensive helium is not wasted. When a long descent is required, you can also choose to release cheap hydrogen first. This greatly reduces the risk of the entire system and is economical.

[0020] 3. The airship adopts hybrid power. Through the combination of photovoltaic electrolysis, power batteries and hydrogen fuel cells, it can achieve full electric propulsion. It mainly relies on power batteries to provide power within a certain distance, which will not affect the operating efficiency. The cruising range after exceeding the range can be extended through the reaction of hydrogen fuel cells, which enhances the safety and reliability of the system; using solar photovoltaic panels to generate electricity for hydrogen production, the generated hydrogen is used for hydrogen fuel cells, and it can also achieve energy self-sufficiency. When hovering at high altitudes, it can replenish hydrogen at any time with extremely high power generation efficiency to ensure sufficient cruising range. The entire system can realize self-production, self-storage and self-use of hydrogen, thus forming a closed-loop energy supply system. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please see attached Figure 1-2 The present invention provides a three-body helium-hydrogen hybrid airship, including an airship frame 10, an electric ducted fan propulsion system 11, a main airbag area, a secondary airbag area, a battery compartment 3 and a pod 4.

[0028] The airship frame 10 uses titanium alloy or high-strength steel in the main force-bearing support part, aviation aluminum alloy or carbon fiber support in the common force-bearing area, and high-strength nylon ropes in the fixing positions of the main airbag area and the auxiliary airbag area.

[0029] The electric ducted fan propulsion system 11 includes a plurality of fans enclosed in the duct, which are driven by a motor to generate thrust and are evenly arranged on both sides of the top of the airship frame 10, and can assist the airship in flying. The motor of the electric ducted fan propulsion system 11 is electrically connected to the battery compartment 3. During the take-off phase, it can be adjusted to vertically downward to help the airship take off quickly. After entering the level flight altitude, it can be rotated to the horizontal direction for propulsion to achieve forward or backward flight. By applying different thrust ratios on both sides for steering, and applying thrust in opposite directions on both sides of the diagonal, the airship can turn around in place. When the airship needs to achieve a short descent, but does not want to let go of some hydrogen or helium, the thrust direction can be made upward to push the airship to land briefly downward, saving some hydrogen. The electric ducted fan propulsion system 11 can also be set as a wind power generation system. When it is suspended without power, it can be adjusted to the windward side so that the fan rotates to generate electricity and charge.

[0030] The airbags in the main airbag area and the auxiliary airbag area are made of multi-layer composite antistatic materials embedded with Kevlar fibers, mainly composed of lightweight, high-strength, weather-resistant and gas-permeability-resistant materials such as polytetrafluoroethylene and polyamide, and conductive metal wires, taking into account the weight, strength, weather resistance, permeability resistance, antistatic effect and cost-effectiveness of the materials.

[0031] The main airbag area is arranged in the middle of the airship frame 10, including a closed helium cabin 9, which is used to provide the main lift for the airship. The closed helium cabin 9 is arranged on both sides of the airship frame 10, and the buoyancy provided by the volume of helium filled therein is approximately equal to the total weight of the airship's own weight and the ballast water. A compressed helium cylinder 7 is also arranged on the inside of the closed helium cabin 9. Although the helium cabin is sealed for storage and is not discharged during the entire life cycle of the airship, due to the molecular leakage of the material, it is still necessary to regularly replenish helium into the closed helium cabin 9 to maintain and ensure that the closed 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 and replenished regularly.

[0032] The auxiliary airbag area is arranged on the upper part of the airship frame 10, provides gas fuel for the battery cabin 3, and also provides 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 on the top of the airship and at the front head position of the airship. Such an arrangement makes the hydrogen mainly located in the upper and front areas of the airship. Even if a leak occurs, due to its own light weight, it can mainly leak upward, and has little impact on the bottom or the rear.

[0033] The helium-hydrogen mixed cabin 2 is filled with a 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 transport oxidants to the hydrogen fuel cell to participate in the hydrogen fuel cell reaction. The mobile helium cabin 5 is arranged between the helium-hydrogen mixed cabin 2 and the oxygen cabin 6 to isolate the helium-hydrogen mixed cabin 2 and the oxygen cabin 6 to prevent leakage or combustion of hydrogen from affecting the oxygen cabin 6.

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

[0035] The battery compartment 3 is installed in the middle of the airship frame 10 along the longitudinal direction of the hull through a slide rail and a roller. The two ends of the slide rail are open and can be removed when the airship is in danger. When there is no risk, the roller of the battery compartment 3 is driven by a motor to slowly translate. The roller is also provided with a locking structure for locking the position of the battery compartment 3, which can adjust the center of gravity distribution of the hull and keep the gravity distribution of the entire boat balanced when different gases are filled in each compartment and different cargoes are carried. When a risk occurs, the connecting wire harness and pipeline of the battery compartment 3 and the outside are cut off, and the slide rail locking structure is released, so that the battery compartment 3 falls off from the front or rear end, reducing the dead weight of the airship, obtaining buoyancy, and ensuring that the main body can descend safely and slowly. Due to the presence of a one-way valve on the pipeline, various gases will not leak. A parachute system and an altitude meter are also provided in the battery compartment 3, 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 to the helium-hydrogen mixed cabin 2, the pure hydrogen cabin 1 located at the head, and the oxygen cabin 6 through a pipeline with a one-way valve. The hydrogen in the helium-hydrogen mixed cabin 2 or the pure hydrogen in the pure hydrogen cabin 1 located at the head is used as the fuel of the hydrogen fuel cell, and oxygen is used as an oxidant to participate in the electrochemical reaction, and the reaction produces water and electricity; during the reaction, helium and hydrogen enter the reaction chamber together, and helium does not participate in the hydrogen fuel cell reaction as an inert gas. The reaction rear end of the hydrogen fuel cell is connected to the helium-hydrogen mixed cabin 2 and the flowing helium cabin 5 through a pipeline with a one-way valve and a multi-way valve, and the reacted helium is filled back into the helium-hydrogen mixed cabin 2 or passed into the flowing helium cabin 5; the reaction rear end of the hydrogen fuel cell is also connected to the closed helium cabin 9 through a pipeline with a one-way valve and a multi-way valve, and the reacted helium is passed into the closed helium cabin 9 for supplementation. The ratio of the top helium-hydrogen mixed cabin 2 / flowing helium cabin 5 can be dynamically adjusted by the flow direction of the helium, so as to achieve precise control of the buoyancy size and distribution area. The switchable multi-way valve connects various pipelines, and different gas flow paths can be quickly switched to connect to the hydrogen fuel cell in a desired manner.

[0037] The hydrogen fuel cell has two working states: when the hydrogen fuel cell is provided with a mixed gas by the helium-hydrogen mixing chamber 2 to react and store energy for the power battery (which can be a lithium-ion battery) or directly power the airship, it is a slow reaction charging / discharging stage, and can be operated when suspended / moving at an economic cruising speed; when the hydrogen fuel cell is provided with pure hydrogen by the pure hydrogen chamber 1 located at the head to participate in the reaction, it is a fast reaction charging / discharging stage, and can be operated when the power battery pack is low and needs to sail at full speed or when the power battery needs to be quickly charged. After the power battery is fully charged, the hydrogen fuel cell stops working. The two working states of the hydrogen fuel cell can be flexibly switched and used, and the generated electrical energy can be supplied to charge the power battery or directly provide power support for the airship; the water generated by the hydrogen fuel cell is passed into the pure water tank to supply 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 supplementation.

[0038] In the slow reaction charging / discharging stage, a hydrogen-helium mixed gas is used for reaction, and pure oxygen in the oxygen cabin 6 can be used to participate in the reaction, and helium can be directly recycled and used; 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 gases such as water, nitrogen, helium and a small amount of carbon dioxide. Since the helium molecule is small, it is easy to penetrate the molecular membrane material (such as metal organic framework (MOF) membrane: ZIF-8_I-43m membrane, or polyimide (PI) and other materials), a molecular membrane can be set at the entrance of the pipeline leading to the helium cabin to achieve the separation and recovery of helium, while nitrogen and carbon dioxide are discharged into the atmosphere. However, this type of separation requires maintaining a high gas pressure and has a high cost, so it is not used as the main method.

[0039] Pure hydrogen is used to participate in the reaction during the fast reaction charge / discharge stage, and air can be used directly for the reaction. At this time, the hydrogen fuel cell mainly emits nitrogen and water after the reaction. In this stage, the gas is not recovered and the nitrogen is directly discharged into the atmosphere.

[0040] Therefore, during the charging and cruising phases, which take up a relatively long time, the hydrogen-helium mixture tank is mainly used to provide the source of reaction gas, and oxygen participates in the reaction. Helium will be recycled during this phase.

[0041] When it is necessary to descend or the oxygen is exhausted, the pure hydrogen tank is used to provide the reaction gas source and react directly with the air. No gas is recovered at this stage.

[0042] During the takeoff preparation phase, cargo will be carried. At this time, the power battery pack will be charged through hydrogen fuel cells or plugged into the mains electricity, and the hydrogen tank will be replenished with gas. The hydrogen-helium mixture tank provides the main source of reaction gas. The helium recovered in this stage can be filled into the helium areas on both sides to provide sufficient lift. After reaching a certain amount, the cable and ballast water can be released for lift. Within the range of endurance, it mainly relies on power batteries for flight. After exceeding the range, it relies on the hydrogen-helium mixture tank and hydrogen fuel cells to provide additional endurance, and can obtain certain supplements through the photovoltaic system at high altitudes.

[0043] The photovoltaic hydrogen production system includes an electrolyzer 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 cabin 9, and the relatively hard surface can provide certain protection for the airbag to a certain extent. The photovoltaic power generation unit is used to power the electrolyzer; the inlet end of the electrolyzer is connected to the pure water tank, and the cathode side of the outlet end is connected to the helium-hydrogen mixed cabin 2 and the pure hydrogen cabin 1 located at the head through a pipeline with a one-way valve and a multi-way valve, and the anode side of the outlet end leads to the oxygen cabin 6. When the airship is hovering in the air and does not consume a lot of energy, the photovoltaic power generation unit can generate electricity to produce hydrogen and oxygen for electrolysis of water, and continuously provide supplementary energy. The electrolyzer is powered by the photovoltaic power generation unit to electrolyze water to produce hydrogen, and the generated hydrogen first fills the helium-hydrogen mixed cabin 2, and then continues to fill the pure hydrogen cabin 1 located at the head and top, and the generated oxygen is filled into the oxygen cabin 6 to supplement the consumption of the hydrogen fuel cell.

[0044] The pod 4 is arranged at the lower part of the airship frame 10 and has a certain energy absorption and collapse capability. A personnel cabin or a cargo cabin can be arranged inside the pod 4 for transporting personnel or large mechanical equipment, such as a wind turbine, etc., and can also store ballast water. An operator cabin 8 is also arranged above the pod 4. Both sides of the pod 4 are provided with lifting and lowering rollers and brackets, or are arranged as air cushion devices.

[0045] When hydrogen leaks or there is a risk of fire, since the risk location is located on the upper part of the airship and the closed helium cabins 9 on both sides of the airship can provide buoyancy equivalent to the airship's own weight, the pod 4 can ensure that it has sufficient buoyancy and ensure the safety of the main structure by discarding cargo or reducing the weight of ballast water.

[0046] The airship of the present invention can easily accommodate the tower and blades of the wind turbine with its excellent transportation capacity, is not affected by the complex road conditions in the mountainous area when performing the transportation task, and can directly fly to the installation site.

[0047] When installing wind turbines in mountainous areas, the airship can fly to the top of the installation point and hover, releasing fixed ropes in four directions. The fixed piles and tractors pre-buried around the installation point will be used to receive these ropes. By wrapping the fixed ropes around the tractor, the airship can be stably fixed. With the coordinated operation of ground personnel, the traction rope guides the airship to slowly descend and hover in the ideal position to maintain stability. Subsequently, the tower and blades are installed in place through hoisting operations. In addition, large airships are also capable of transporting heavy construction machinery and equipment such as excavators. This innovative transportation and installation method will significantly reduce the transportation and installation costs of wind turbines, while simplifying the installation process and reducing the difficulty of construction.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
