Description

Technical Field

[0001] The present application relates to the technical field of fuel cells, and in particular to a hydrogen production system for unmanned aerial vehicles. Background Art

[0002] At present, small and light rotary-wing / fixed-wing drones are increasingly used in daily life. Plant protection drones, inspection drones, rescue drones, etc. play a very important role.

[0003] Drones are usually powered by lithium batteries, but their battery life is relatively short. To increase the battery life, the weight and volume of the batteries must be increased, but this will undoubtedly take up the drone's transportation space and payload. Some drones have increasingly higher requirements for battery life, so lithium batteries are unlikely to meet the requirements in a short period of time.

[0004] Therefore, hydrogen fuel cells are proposed, and carrying hydrogen storage bottles can improve the endurance of drones to a certain extent, and do not need to take up too much transportation space and are also light in weight. However, hydrogen refueling still has certain difficulties.

[0005] In this regard, the patent with publication number CN116979108A ​​discloses a drone hydrogen fuel cell system, which has a control unit, a hydrogen supply unit, a fuel cell unit and a power management unit. The hydrogen supply unit includes a storage tank, a reactor and a purification cooler. The storage tank is used to store solid or liquid hydrogen production reactants. The storage tank is connected to the reactor and the quantitative delivery of the reactants is achieved through a metering pump to control the hydrogen production speed. The reactor is connected to the purification cooler, and the purification cooler is connected to the air inlet of the fuel cell unit. The above solution solves the problems of difficult transportation, difficult inflation and poor flexibility of traditional fuel cells.

[0006] However, since the above scheme uses a metering pump to transport the reactants from the storage tank to the reactor, the hydrogen production speed will be limited by the reactor, that is, when the reactants introduced into the reactor exceed a certain amount, the hydrogen production speed will no longer increase. When the energy consumption of the drone is high, the hydrogen obtained by the fuel cell may be insufficient, so the above scheme still has shortcomings in controlling the hydrogen production speed.

[0007] Therefore, how to ensure that drones can obtain sufficient hydrogen supply under different energy consumption conditions to meet the power consumption in different scenarios still needs further optimization. Summary of the invention

[0008] The present application provides a UAV hydrogen production system, which has the advantages of fast hydrogen production speed, sufficient hydrogen supply and a wide adjustable range of hydrogen supply speed, and adopts the following technical solutions: A hydrogen production system for a drone, comprising a storage tank, a feeding pipeline, a reaction tank and a hydrogen supply pipeline; The reaction tanks are provided with a plurality of them, and the feeding pipeline includes a material distribution plate and a delivery pipe; the material distribution plate has a plurality of material distribution valves, and the plurality of material distribution valves are all connected to the storage tank; the plurality of material distribution valves correspond to the plurality of reaction tanks one by one and are connected through the delivery pipe; The hydrogen supply pipeline includes an air supply pipe and a control valve.

One end of the transfer tube is plugged in with the connecting needle in an interference fit, which improves the sealing and stability of the connection and prevents material leakage. The other end of the transfer tube is fixedly connected to the conveying pipe, ensuring the smoothness and stability of the entire feeding process, and improving the reliability and safety of the system.

[0018] Preferably, it further comprises a storage bin, wherein the reaction tank is disposed in the storage bin and is detachably arranged; the connection cap is fixedly connected to the air inlet plug via a fixing plate, and the fixing plate is fixedly connected to the storage bin.

[0019] By adopting the above technical solution, the reaction tank of the hydrogen production system of the drone is arranged in the storage bin and is detachable, which is convenient for replacing and maintaining the reaction tank, and improves the flexibility and convenience of the system. At the same time, the connection cap is fixedly connected to the gas inlet plug through a fixing plate, and the fixing plate is fixedly connected to the storage bin, which ensures the stability and reliability of the connection, prevents the connection from loosening or falling off due to vibration during the flight of the drone, and ensures the safety and stability of the system.

The main control valve is arranged between the gas collecting pipe and the gas supply pipe, which further enhances the controllability of the system and ensures a stable supply of hydrogen. In summary, this design scheme significantly improves the flexibility, reliability and stability of the system's hydrogen supply.

[0022] Preferably, the gas supply pipe is also connected to a plurality of gas distribution pipes, and a plurality of fuel cells are provided, and each of the gas distribution pipes is connected to a fuel cell in a one-to-one correspondence.

[0029] The following is combined with Figure 1-5 The present invention is described in further detail.

[0030] The present application embodiment discloses a hydrogen production system for drones, referring to Figure 1 The invention comprises a storage tank 1, a feeding pipeline 2, a reaction tank 3 and a hydrogen supply pipeline 4. By setting a plurality of reaction tanks 3 and a material distribution valve 211, multi-point hydrogen production is achieved, the hydrogen production efficiency of the system is improved, and the effect of improving the endurance and flexibility of the drone is achieved. The application is further described in detail below.

[0031] Reference Figure 2 and Figure 3 Specifically, a plurality of storage tanks 1 are provided and arranged in parallel. The storage tanks 1 are arranged vertically, and the bottoms of two adjacent storage tanks 1 are connected by a material mixing pipe 11, and the tops are connected to each other by an exhaust pipe 12.

[0032] Specifically, the number of storage tanks 1 can be adjusted according to the endurance requirements of the drone, and it is generally recommended to set 2-4 storage tanks 1. The function of the material mixing pipe 11 is to evenly distribute the reactants among the multiple storage tanks 1 to avoid excessive concentration or insufficient reactants in a certain storage tank 1. The exhaust pipe 12 is used to discharge the gas in the storage tank 1 to avoid the reactants from having difficulty entering the storage tank 1 due to the presence of gas in the storage tank 1. In addition, a filling port 13 can be set on one of the storage tanks 1 so that the reactants in the storage tank 1 can be quickly replenished when the reactants are insufficient.

[0033] By providing a plurality of storage tanks 1 and mixing pipes 11, uniform distribution of reactants can be achieved. This design further improves the stability and safety of the system and is suitable for the endurance requirements of drones in different scenarios.

[0034] Furthermore, the material distribution plate 21 includes multiple material distribution valves 211 and connecting pipes 212, and the connecting pipes 212 are connected to one of the storage tanks 1, and the connecting pipes 212 can be flexibly selected to be connected to different storage tanks 1 to avoid the problem of failure of a single storage tank 1 causing it to be unusable.

[0035] Each dispensing valve 211 is arranged on a connecting pipe 212, and the reactants in the storage tank 1 can be transported to the dispensing valve 211 through the connecting pipe 212. The dispensing valve 211 can be a solenoid valve or a pneumatic valve, both of which can achieve fast response and precise control.

[0036] The delivery pipe 22 is a pipeline connecting the dispensing valve 211 and the reaction tank 3. Corresponding to the multiple dispensing valves 211, multiple delivery pipes 22 are also provided, and one end of the delivery pipe 22 is connected to the dispensing valve 211, and the other end is connected to the reaction tank 3 to ensure that the reactants can stably enter the reaction tank 3.

[0037] Reference Figure 2 , Figure 3 and Figure 4 Furthermore, in order to achieve a stable connection between the delivery tube 22 and the reaction tank 3, a feed interface 31 is provided on the reaction tank 3, and a feed plug 23 is connected to the end of the delivery tube 22. The feed plug 23 includes a connection cap 231, a connection needle 232 and a transfer tube 233. The connection cap 231 is sleeved on the feed interface 31, and the connection needle 232 is fixedly connected and communicated with the connection cap 231. One end of the transfer tube 233 is plugged with the connection needle 232 by interference, and the other end is fixedly connected to the delivery tube 22.

[0038] The reaction tank 3 is the core component of hydrogen production, and a heating device and a stirring device may be added therein to accelerate the chemical reaction rate of the reactants.

[0039] Reference Figure 3 and Figure 4The hydrogen supply pipeline 4 includes an air supply pipe 41 and a control valve 42. The air supply pipe 41 is a pipeline network composed of a main pipe 411 and a plurality of branch pipes 412. The plurality of branch pipes 412 are connected to the reaction tank 3 in a one-to-one correspondence, and in order to facilitate the rapid disassembly and assembly of the reaction tank 3 and the branch pipes 412, a hydrogen interface 32 is provided on the reaction tank 3. The hydrogen interface 32 and the feed interface 31 are located at one end of the reaction tank 3 and are arranged adjacent to each other. A gas connection plug 43 is provided at the end of the branch pipe 412, and the gas connection plug 43 is plugged and matched with the hydrogen interface 32.

[0040] In addition, the gas connection plug 43 and the connection cap 231 of the feed plug 23 can be fixedly connected. Specifically, a fixing plate 44 is added to the gas connection plug 43 and the feed plug 23, and the gas connection plug 43 and the connection cap 231 are fixedly connected to the fixing plate 44 to achieve synchronous docking of the gas connection plug 43 and the feed plug 23 with the reaction tank 3, thereby improving the convenience of operation. The gas connection plug 43 is set as a one-way valve to prevent the hydrogen in the gas supply pipe 41 from flowing back into the reaction tank 3.

[0041] At the same time, the design of the gas connection plug 43 and the feed plug 23 should be considered to have sufficient sealing properties to prevent the leakage of reactants and hydrogen, thereby causing system failure or even explosion.

[0042] Reference Figure 5 The drone hydrogen production system in the present application also includes a storage bin 5, and a fixing plate 44 is fixedly connected to the side wall of the storage bin 5 to fix the gas connection plug 43 and the feed plug 23. The reaction tank 3 is detachably arranged in the storage bin 5, and the connection method can be a snap-on type or other structural form that can achieve disassembly and assembly. Therefore, when the reaction tank 3 is fixed in the storage bin 5, the gas connection plug 43 and the feed plug 23 can automatically dock with the reaction tank 3.

[0043] Reference Figure 4 , the main pipe 411 includes an air collecting pipe 4111 and an air supply pipe 4112, and multiple air collecting pipes 4111 are provided. Correspondingly, multiple reaction tanks 3 are divided into multiple groups, each group includes two or more reaction tanks 3; each group of reaction tanks 3 corresponds to an air collecting pipe 4111, and the air collecting pipe 4111 is connected to the corresponding branch pipe 412. Specifically, in an embodiment of the present application, the reaction tanks 3 are set to three groups, and three air collecting pipes 4111 are correspondingly provided. The reaction tanks 3 of the same group are connected to the corresponding air collecting pipes 4111 through the branch pipe 412. Multiple air collecting pipes 4111 are then connected to the air supply pipe 4112.

[0044] The control valve 42 includes a main control valve 421 and a sub-control valve 422. The sub-control valve 422 is arranged on the gas collecting pipe 4111 to control the on-off of each gas collecting pipe 4111; the main control valve 421 is arranged between the gas collecting pipe 4111 and the gas supply pipe 4112 to control the on-off between the gas collecting pipe 4111 and the gas supply pipe 4112.

[0045] Both the main control valve 421 and the sub-control valve 422 can be electric valves or pneumatic valves, both of which can be remotely controlled and automatically adjusted. The opening and closing action of the control valve 42 is controlled by the control system through an electrical signal or a gas pressure signal to ensure that the delivery amount and delivery time of hydrogen are accurately controlled. It is worth noting that since hydrogen is a flammable and explosive gas, the control valve 42 used should be an explosion-proof valve.

[0046] Reference Figure 4 and Figure 5 Furthermore, the gas supply pipe 4112 is also connected to a plurality of gas distribution pipes 45, and a plurality of fuel cells 6 are provided, and each gas distribution pipe 45 is connected to a fuel cell 6 in a one-to-one correspondence. In addition, an air pump 46 is provided on each gas distribution pipe 45 to ensure that hydrogen can be evenly distributed to each fuel cell 6, thereby improving the overall performance of the system.

[0047] The selection of the air pump 46 should take into account its power, service life and explosion-proof performance. The air pump 46 is powered by the fuel cell 6, so it is recommended to use an energy-efficient air pump 46 to reduce energy consumption. The installation position of the air pump 46 should be as close as possible to the end of the gas supply pipe 4112 to reduce the loss of hydrogen during transportation.

[0048] Thus, by providing the gas distribution pipe 45 and the gas pump 46, the uniform distribution and efficient delivery of hydrogen can be achieved, further improving the stability and reliability of the system. This design is particularly suitable for complex application scenarios that require multiple fuel cells 6 to work simultaneously, such as long-range drones or multi-task drones.

[0049] The implementation principle of a drone hydrogen production system in the embodiment of the present application is as follows: the design of multiple reaction tanks allows the hydrogen production process to be carried out simultaneously, thereby improving the overall hydrogen production speed of the system, ensuring that the drone can obtain sufficient hydrogen supply under different energy consumption conditions, and solving the problem of limited hydrogen production speed in traditional solutions; the setting of the distribution plate and the distribution valve realizes the precise distribution of reactants, avoids the decrease in hydrogen production efficiency due to excessive reactants, and ensures the stable operation of the system; the design of the control valve and the hydrogen supply pipeline makes the transportation of hydrogen more flexible and controllable, and the hydrogen flow rate can be adjusted according to actual needs, thereby improving the adaptability and reliability of the system.

[0050] In a specific application, a certain amount of hydrogen can be stored in the reaction tank 3, and the output rate of hydrogen can be flexibly adjusted through the control valve 42 to meet the hydrogen demand of the fuel cell under different energy consumption.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
