Description

Technical Field

[0001] This invention relates to the field of mechanical dog technology, specifically to a mechanical dog power unit based on a hydrogen fuel cell that can automatically refuel. Background Technology

[0002] Robotic dogs are now widely used in various aspects of life, and the era of robotic dogs has arrived. Increased demand for robotic dogs has placed new requirements on their environmental adaptability, functionality, safety, and stability. Traditional robotic dogs mostly use wheels or tracks to move in various environments, relying on their interaction with the ground. The advantage of this method is its convenience and speed, but the disadvantage is that its applicability is very limited, only applicable to flat terrain and relatively simple environments.

[0003] The main components of the hydrogen-powered robotic dog include a hydrogen fuel supply system (hydrogen tank, hydrogen valve, hydrogen pipeline), a power core (hydrogen fuel cell or hydrogen engine), a bionic movement mechanism (multi-jointed legs, drive motor / hydraulic device, bionic hooves), an intelligent control module (AI chip, sensor group, navigation system), and energy storage and auxiliary components (lithium battery, communication module, status monitor). In use, first check the hydrogen tank's sealing and remaining amount. After confirming there are no leaks, add hydrogen using specialized equipment. Then start the power system. Once the hydrogen fuel cell / engine is running stably and the control system has passed its self-test, send commands via remote control or terminal device to select autonomous navigation or manual control mode.

[0004] When hydrogen-powered mechanical dogs electrolyze water to produce hydrogen, a stable and sufficient water source is required. In field operations, convenient and sustainable water supply can only rely on natural water sources such as streams, lakes, and snowmelt. However, natural water sources contain impurities such as silt, microorganisms, and heavy metals. If used directly for electrolysis, it can lead to scaling on the electrodes of the electrolyzer, clogging of the membrane components, reduced electrolysis efficiency, and may also cause equipment corrosion failure. Natural water sources often contain impurities such as silt, dead branches, and plankton, which can easily clog the pre-filter and ultrafiltration membrane, causing a sudden drop in water flow rate, decreased purification efficiency, and in severe cases, system pressure overload shutdown. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem this application aims to solve is: when hydrogen-powered mechanical dogs electrolyze water to produce hydrogen, a stable and sufficient water source is required. In field operation scenarios, convenient and sustainable water supply can only rely on wild water sources such as streams, lakes, and snowmelt. However, wild water sources contain impurities such as silt, microorganisms, and heavy metals. If used directly for electrolysis, it will lead to scaling on the electrodes of the electrolyzer, clogging of the membrane components, reduced electrolysis efficiency, and may also cause equipment corrosion failure. Wild water sources often contain impurities such as silt, dead branches, and plankton, which can easily clog the pre-filter and ultrafiltration membrane, causing a sudden drop in water flow rate and a decrease in purification efficiency. In severe cases, it can cause system pressure overload and shutdown.

The positioning shafts 721 installed on the positioning plate 72 can support and fix the pressure device 7 in the device, ensuring the stability of the device during use. At the same time, the flange 731 installed between the connecting pipe 73 and the vertical rod 71 is used to ensure that the solution in the device can flow normally and avoid leakage.

[0041] Reference Figures 5-7 A water pump 6 is fixedly installed on the side wall of the positioning frame 5. The water pump 6 is connected to the transport pipe 53. The water pump 6 installed on the positioning frame 5 provides power to the device.

[0042] Reference Figures 5-8 A support plate 55 is fixedly installed on the bottom of the positioning frame 5, and the bottom surface of the support plate 55 is rough. The support plate 55 installed on the positioning frame 5 can fix the positioning frame 5, ensuring its stability and safety during operation.

[0043] The specific steps of this solution are as follows: Staff first assemble the device and then place it in the designated position. The support rod 4 and anti-slip sleeve 41 on the main body ensure the mechanical dog can operate normally. The friction provided by the anti-slip sleeve 41 prevents slippage during movement.
