Description

TECHNICAL FIELD

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

[0002] At present, small and light rotary-wing / fixed-wing unmanned aerial vehicles are increasingly applied to daily life, such as plant protection unmanned aerial vehicles, inspection unmanned aerial vehicles, rescue unmanned aerial vehicles, and the like, which play a very important role.

[0003] The energy supply of unmanned aerial vehicles is usually lithium batteries, but the endurance is short. In order to improve the endurance, the weight and volume of the battery need to be increased, which undoubtedly occupies the transportation space and effective load of the unmanned aerial vehicle. For some unmanned aerial vehicles, there is an increasingly high requirement for endurance, so it is difficult for lithium batteries to meet the requirements in a short time.

[0004] Therefore, a hydrogen fuel cell is proposed, which carries a hydrogen storage bottle, can improve the endurance of the unmanned aerial vehicle to a certain extent, and does not need to occupy too much transportation space and has a lighter weight. However, hydrogen refueling still has certain difficulties.

[0005] To this end, the patent with publication number CN116979108A discloses a hydrogen fuel cell system for unmanned aerial vehicles, 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 in communication with the reactor, and the reactants are quantitatively delivered by a metering pump to control the hydrogen production speed. The reactor is in communication with the purification cooler, and the purification cooler is in communication with the gas inlet of the fuel cell unit. The above-mentioned scheme solves the problems of difficult transportation, difficult refueling and poor flexibility of traditional fuel cells.

[0006] However, since the above-mentioned scheme uses a metering pump to deliver the reactants from the storage tank to the reactor, the hydrogen production speed is limited by the reactor. That is, when the amount of reactants introduced into the reactor exceeds a certain amount, the hydrogen production speed no longer increases. When the energy consumption of the unmanned aerial vehicle is high, the hydrogen obtained by the fuel cell may be insufficient, so the above-mentioned scheme still has deficiencies in hydrogen production speed control.

[0007] Therefore, how to ensure that the unmanned aerial vehicle can obtain sufficient hydrogen supply under different energy consumptions to meet the electrical energy consumption in different scenarios still needs to be further optimized. SUMMARY

[0041] The following will be described in detail in combination with the drawings Figures 1-5 Further detailed description of the present application.

[0042] The embodiment of the present application discloses an unmanned aerial vehicle hydrogen production system, referring to Figure 1 which comprises a storage tank 1, a feeding pipeline 2, a reaction tank 3 and a hydrogen supply pipeline 4, by setting multiple reaction tanks 3 and distribution valves 211, multi-point hydrogen production is realized, the hydrogen production efficiency of the system is improved, and the effect of improving the endurance and flexibility of the unmanned aerial vehicle is achieved.

The storage tanks 1 are vertically arranged, and the bottoms of adjacent two storage tanks 1 are connected through the uniform material pipes 11, and the tops are communicated with each other through the exhaust pipes 12.

[0044] Specifically, the number of the storage tanks 1 can be adjusted according to the endurance requirement of the unmanned aerial vehicle, and it is generally recommended to set 2-4 storage tanks 1. The role of the uniform material pipe 11 is to uniformly distribute the reactants among the multiple storage tanks 1, so as to avoid excessive concentration or deficiency of the reactants in a certain storage tank 1. The exhaust pipe 12 is used to exhaust the gas in the storage tank 1, so as to avoid the difficulty of the reactants entering the storage tank 1 due to the existence of the gas in the storage tank 1. In addition, a material injection port 13 can be arranged on one of the storage tanks 1, so as to facilitate the rapid replenishment when the reactants in the storage tank 1 are insufficient.

[0045] By arranging multiple storage tanks 1 and uniform material pipes 11, uniform distribution of the reactants can be realized, and this design scheme further improves the stability and safety of the system, and is suitable for the endurance requirement of the unmanned aerial vehicle in different scenes.

[0046] Further, the material distribution disc 21 includes multiple material distribution valves 211 and connecting pipes 212, the connecting pipe 212 is connected with one of the storage tanks 1, and the connecting pipe 212 can be flexibly selected to be connected with different storage tanks 1, so as to avoid the problem that a single storage tank 1 fails and cannot be used.

[0047] Each material distribution valve 211 is arranged on the connecting pipe 212, and the reactants in the storage tank 1 can be transported to the material distribution valve 211 through the connecting pipe 212. The material distribution valve 211 can adopt an electromagnetic valve or a pneumatic valve, and both of the two valves can realize fast response and accurate control.

[0048] The conveying pipe 22 is a pipeline connecting the material distribution valve 211 and the reaction tank 3. Corresponding to the multiple material distribution valves 211, the conveying pipe 22 is also provided in multiple, and one end of the conveying pipe 22 is connected with the material distribution valve 211, and the other end is connected with the reaction tank 3, so as to ensure that the reactants can stably enter the reaction tank 3.

[0049] Referring to Figure 2 , Figure 3 and Figure 4 Further, in order to realize the stable connection of the conveying pipe 22 and the reaction tank 3, the reaction tank 3 is provided with a material inlet interface 31, and the conveying pipe 22 is provided with a feeding plug 23 at the end. The feeding plug 23 includes a connecting cap 231, a connecting needle 232 and an adapter pipe 233. The connecting cap 231 is sleeved on the material inlet interface 31, and the connecting needle 232 is fixedly connected with the connecting cap 231 and is in communication.

[0050] The reaction tank 3 is the core component of the hydrogen production, and a heating device and a stirring device can be additionally arranged inside the reaction tank 3 to accelerate the chemical reaction rate of the reactants.

[0051] With reference to Figure 3 and Figure 4 , the hydrogen supply pipeline 4 includes a gas feeding pipe 41 and a control valve 42. The gas feeding 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 one by one, and in order to facilitate the quick disassembly and assembly of the reaction tank 3 and the branch pipe 412, a hydrogen gas interface 32 is arranged on the reaction tank 3. The hydrogen gas interface 32 is located at one end of the reaction tank 3 and is arranged adjacent to the feed interface 31. The end of the branch pipe 412 is provided with a gas connection plug 43, and the gas connection plug 43 is inserted and matched with the hydrogen gas interface 32.

[0052] In addition, the connection cap 231 of the gas connection plug 43 and the feeding plug 23 can be fixedly connected, specifically, a fixing plate 44 is additionally arranged at the gas connection plug 43 and the feeding plug 23, and the gas connection plug 43 and the connection cap 231 are fixedly connected with the fixing plate 44, so as to realize the synchronous docking of the gas connection plug 43 and the feeding plug 23 with the reaction tank 3 and improve the convenience of operation. The gas connection plug 43 is arranged as a one-way valve to prevent the hydrogen gas in the gas feeding pipe 41 from flowing back to the reaction tank 3.

[0053] At the same time, for the design of the gas connection plug 43 and the feeding plug 23, sufficient sealing should be considered to avoid leakage of the reactants and hydrogen gas, thereby causing system failure or even explosion.

[0054] With reference to Figure 5 , the unmanned aerial vehicle hydrogen production system in the application further includes a storage bin 5, and the fixing plate 44 is fixedly connected with the side wall of the storage bin 5 to fix the gas connection plug 43 and the feeding plug 23. The reaction tank 3 can be detachably arranged in the storage bin 5, and the connection mode can adopt a buckle type or other structure capable of realizing disassembly and assembly. Therefore, when the reaction tank 3 is fixed in the storage bin 5, the gas connection plug 43 and the feeding plug 23 can be automatically docked with the reaction tank 3.

[0055] With reference to Figure 4 , the main pipe 411 includes a gas collecting pipe 4111 and a gas supply pipe 4112, and the gas collecting pipe 4111 is provided with a plurality of gas collecting pipes 4111. Correspondingly, the plurality of reaction tanks 3 are divided into a plurality of groups, and each group contains two or more reaction tanks 3; each group of reaction tanks 3 corresponds to one gas collecting pipe 4111, and the gas collecting pipe 4111 is connected with the corresponding branch pipe 412. Specifically, in the embodiment of the application, the reaction tank 3 is arranged in three groups, and three gas collecting pipes 4111 are correspondingly arranged. The reaction tanks 3 in the same group and the corresponding gas collecting pipe 4111 are connected through the branch pipe 412. The plurality of gas collecting pipes 4111 are connected with the gas supply pipe 4112.

[0056] The control valve 42 includes a master 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 opening and closing of each gas collecting pipe 4111. The master control valve 421 is arranged between the gas collecting pipe 4111 and the gas supply pipe 4112 to control the opening and closing between the gas collecting pipe 4111 and the gas supply pipe 4112.

[0057] Both the master control valve 421 and the sub-control valve 422 can be electric or pneumatic valves, both of which can be remotely controlled and automatically adjusted. The opening and closing actions of the control valve 42 are controlled by the control system through electrical or pneumatic signals to ensure that the hydrogen delivery amount and delivery time 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.

[0058] Referring to Figure 4 and Figure 5 , further, the gas supply pipe 4112 is also connected to a plurality of gas distribution pipes 45, and the fuel cell 6 is provided with a plurality of fuel cells 6, each gas distribution pipe 45 is connected to a fuel cell 6 one by one. In addition, a gas pump 46 is arranged on each gas distribution pipe 45 to ensure that hydrogen can be uniformly distributed to each fuel cell 6, improving the overall performance of the system.

[0059] The selection of the gas pump 46 should consider its power, working life and explosion-proof property. The gas pump 46 is powered by the fuel cell 6, so it is recommended to use a high-efficiency energy-saving gas pump 46 to reduce energy consumption. The installation position of the gas pump 46 should be as close to the end of the gas supply pipe 4112 as possible to reduce the loss of hydrogen during transportation.

[0060] Therefore, by arranging the gas distribution pipe 45 and the gas pump 46, uniform distribution and efficient transportation of hydrogen can be achieved, further improving the stability and reliability of the system. This design scheme is particularly suitable for complex application scenarios that require multiple fuel cells 6 to work simultaneously, such as long-range unmanned aerial vehicles or multi-task unmanned aerial vehicles.

[0061] The implementation principle of the unmanned aerial vehicle hydrogen production system in the embodiment of the application is that the design of multiple reaction tanks enables the hydrogen production process to be carried out simultaneously, improving the overall hydrogen production speed of the system and ensuring that the unmanned aerial vehicle can obtain sufficient hydrogen supply under different energy consumption conditions, solving the problem of limited hydrogen production speed in traditional schemes; the arrangement of the distribution disc and the distribution valve realizes precise distribution of the reactants, avoiding the decrease of hydrogen production efficiency caused by excessive reactants and ensuring 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, which can adjust the flow of hydrogen according to actual needs, improving the adaptability and reliability of the system.

[0062] In specific applications, 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 consumptions.

[0063] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
