Description

Technical Field

[0001] This utility model relates to the field of power vehicle technology, specifically to a power vehicle with a hydrogen system. Background Technology

[0002] With the rapid development of new energy technologies, hydrogen energy, due to its high energy density, zero carbon emissions, and renewability, is gradually becoming an important energy form for power emergency and distributed energy supply systems. A hydrogen system power vehicle is a mobile energy supply device that integrates a hydrogen fuel cell system, hydrogen storage device, and power conversion device on a vehicle platform. It can provide independent power support for communication base stations, medical equipment, or military equipment in field operations, emergency rescue, temporary power supply, and special environments.

[0003] CN209675412U discloses a gas-fueled electric vehicle and an on-board hydrogen storage system, including at least two sets of hydrogen storage components installed in the vehicle compartment. Each set of hydrogen storage components has an intake valve between its intake pipe and the hydrogen fuel cell. The intake valve is connected to a controller. The intake pipe is connected to a main pipe, which is connected to the hydrogen fuel cell. The main pipe has a main control valve that controls the pipe switch and is connected to the controller. Each set of hydrogen storage components has a hydrogen refueling valve for adding hydrogen.

[0004] The aforementioned existing technologies have the following shortcomings:

[0005] The two hydrogen storage modules of this gas-fueled vehicle are arranged in a decentralized manner, with each module installed independently in different areas of the vehicle compartment. This results in low overall system integration and low space utilization. Due to the large distance between the hydrogen storage modules, the pipeline connections are numerous, long, and complex, which not only increases the pressure drop and energy loss during hydrogen transportation, but also increases the risk of hydrogen leakage and maintenance difficulty to some extent. Utility Model Content

[0006] The purpose of this invention is to provide a power vehicle for a hydrogen system, which solves the problems of low system integration, complex pipeline connections, low hydrogen transportation efficiency, and inconvenient maintenance and operation caused by the dispersed arrangement of hydrogen storage components in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A hydrogen-powered vehicle, comprising:

[0009] The compartments include a hydrogen storage system compartment with its own independent space;

[0010] Hydrogen storage components, including a hydrogen storage rack and multiple hydrogen storage tanks;

[0011] The hydrogen storage rack includes a base, horizontal frames, and vertical frames;

[0012] The vertical frame is arranged vertically and fixed to the base, and the horizontal frame is arranged horizontally and fixedly connected between the vertical frames to form multiple tank installation spaces for accommodating the hydrogen storage tanks; each of the hydrogen storage tanks has an inlet end and an outlet end at both ends.

[0013] The pipeline assembly is connected to the inlet and outlet of the hydrogen storage tank, respectively, and is used to connect the inlet or outlet of the multiple hydrogen storage tanks.

[0014] A further technical solution is that the hydrogen storage tanks are arranged in multiple layers along the height direction of the longitudinal frame.

[0015] A further technical solution is that the hydrogen storage tank is fixed to the crossbeam by a fixing component; the fixing component includes a steel rope, a steel plate sleeve, a steel column, a screw, a rotating bar, and a nut; the nut is fixed to the crossbeam; one end of the screw is threadedly connected to the nut; the rotating bar is fixedly sleeved on the screw; the rotating bar is fixed to the end of the screw away from the nut; the steel rope is wound around the rotating bar, and the steel rope is clamped and riveted by the steel plate sleeve; the rotating bar can rotate the screw threaded connection into the nut, thereby driving the steel rope to tighten the hydrogen storage tank.

[0016] A further technical solution is to fix a vibration damping pad between the hydrogen storage tank and the steel rope.

[0017] A further technical solution is that the pipeline assembly includes an inlet main pipe, an outlet main pipe, and multiple connecting branch pipes; one end of each connecting branch pipe is connected to the inlet main pipe or the outlet main pipe, and the other end is connected to the inlet end or the outlet end, so that the inlet ends or outlet ends of the multiple hydrogen storage tanks are connected together.

[0018] A further technical solution is that the inlet end or the outlet end is provided with a two-way interface; the end of the connecting branch pipe away from the main inlet pipe or the main outlet pipe is connected to one end of the two-way interface; and two adjacent hydrogen storage tanks are connected by a gas replenishment branch pipe.

[0019] A further technical solution is that the outer side of the compartment is equipped with double doors facing the hydrogen storage system compartment.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By installing an independent hydrogen storage system compartment on the power vehicle and employing a modular hydrogen storage rack structure within the compartment, a centralized and layered arrangement of multiple hydrogen storage tanks is achieved. Compared to the existing technology where hydrogen storage tanks are installed separately and connected by lengthy pipelines, this solution arranges the hydrogen storage tanks in a matrix layout along both the longitudinal and transverse directions, significantly improving the system's integration and space utilization. This makes the hydrogen delivery pipeline more centralized and concise, reducing the number of joints and the risk of leakage. By connecting the inlet and outlet ends of each hydrogen storage tank through pipeline components, the pipeline connection process is simplified, and the hydrogen refueling and supply processes become more efficient and stable. This reduces hydrogen transmission resistance and improves the overall safety and transmission efficiency of the system. Furthermore, the centralized arrangement facilitates system maintenance and replacement operations, avoiding the cumbersome steps of disassembling each tank individually during maintenance, as required by traditional decentralized structures, thus improving the convenience and reliability of equipment maintenance.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example:

[0030] like Figures 1-4As shown, this utility model provides a hydrogen system power vehicle, including a compartment 1, a hydrogen storage assembly 2, and a pipeline assembly 3; the compartment 1 includes a hydrogen storage system compartment 11 with independent space; the hydrogen storage assembly 2 includes a hydrogen storage rack 21 and multiple hydrogen storage tanks 22; the hydrogen storage rack 21 includes a base 211, a crossbar 212, and a longitudinal rack 213; the longitudinal rack 213 is arranged vertically and fixed on the base 211, and the crossbar 212 is arranged horizontally and fixedly connected between the longitudinal racks 213 to form multiple tank installation spaces for accommodating the hydrogen storage tanks 22; each hydrogen storage tank 22 has an inlet end 221 and an outlet end at both ends; the pipeline assembly 3 is connected to the inlet end 221 and the outlet end of the hydrogen storage tank 22, respectively, for connecting the inlet ends 221 or the outlet ends of multiple hydrogen storage tanks 22;

[0031] The principles and beneficial effects of the above technical solution:

[0032] By setting up an independent hydrogen storage system compartment 11 on the power vehicle and adopting a modular hydrogen storage rack structure 21 within the compartment, a centralized and layered arrangement of multiple hydrogen storage tanks 22 is achieved. Compared with the existing technology where hydrogen storage tanks 22 are installed separately and connected by long pipelines, this solution forms a matrix layout of hydrogen storage tanks 22 in both longitudinal and transverse directions, significantly improving the system's integration and space utilization, making the hydrogen transmission pipeline more centralized and concise, and reducing the number of joints and the risk of leakage.

[0033] By connecting the gas inlet 221 and gas outlet of each hydrogen storage tank 22 through the pipeline assembly 3, the pipeline connection process is simplified, the hydrogen addition and supply process is made more efficient and stable, the hydrogen transmission resistance is reduced, and the overall safety and transmission efficiency of the system are improved.

[0034] Meanwhile, the centralized layout facilitates system maintenance and replacement operations, avoiding the cumbersome steps of disassembling tank by tank during maintenance in traditional decentralized structures, thus improving the convenience and reliability of equipment maintenance.

[0035] In this embodiment, the hydrogen storage tank 22 is arranged in multiple layers along the height direction of the longitudinal frame 213.

[0036] The principles and beneficial effects of the above technical solution:

[0037] This allows for a three-dimensional arrangement of the hydrogen storage tanks 22 within the limited cabin space, which not only improves the utilization rate of the cabin volume but also increases the hydrogen storage capacity under the same floor area. The multi-layered distribution is beneficial for the balance of the center of gravity, improving the stability of the vehicle during driving and turning, and avoiding the force shift caused by the concentration of hydrogen storage modules on a single plane.

[0038] In this embodiment, the hydrogen storage tank 22 is fixed to the crossbeam 212 by a fixing member 4; the fixing member 4 includes a steel rope 41, a steel plate sleeve 42, a steel column 43, a screw 44, a rotating bar 45, and a nut 46; the nut 46 is fixed to the crossbeam 212; one end of the screw 44 is threadedly connected to the nut 46; the rotating bar 45 is fixedly sleeved on the screw 44; the rotating bar 45 is fixed to the end of the screw 44 away from the nut 46; the steel plate sleeve 42 is wound around the rotating bar, and the steel rope 41 is clamped and riveted by the steel plate sleeve 42; the rotating bar 45 can turn the screw 44 threadedly into the nut 46, driving the steel rope 41 to tighten the hydrogen storage tank 22.

[0039] The principles and beneficial effects of the above technical solution:

[0040] The hydrogen storage tank 22 is quickly fixed and released via a tensioning mechanism consisting of steel rope 41, screw 44, nut 46, and rotating bar 45. Utilizing the mechanical tensioning principle, the steel rope 41 is tensioned by rotating the screw 44. The fixing force can be flexibly adjusted according to the outer diameter and spacing of the hydrogen storage tank 22, ensuring that the hydrogen storage tank 22 does not loosen or shift under vehicle vibration conditions. Simultaneously, the steel sheet sleeve 42 and riveting structure strengthen the end fixation of the steel rope 41, improving tensile strength and reliability. Compared to traditional welding or rigid clamp fixing, this structure is adjustable and maintainable, facilitating disassembly and replacement.

[0041] In this embodiment, a vibration damping pad 5 is fixed between the hydrogen storage tank 22 and the steel rope 41.

[0042] The principles and beneficial effects of the above technical solution:

[0043] The vibration damping pad 5 is made of high-temperature and pressure-resistant rubber or composite material, and is used to absorb the impact and vibration during driving, and prevent the hydrogen storage tank 22 from directly contacting the metal fixing part 4 to cause stress concentration or wear.

[0044] like Figure 4 As shown, in this embodiment, the pipeline assembly 3 includes an inlet main pipe 31, an outlet main pipe, and multiple connecting branch pipes 32; one end of the connecting branch pipe 32 is connected to the inlet main pipe 31 or the outlet main pipe, and the other end is connected to the inlet end 221 or the outlet end, so that the inlet ends 221 or the outlet ends of multiple hydrogen storage tanks 22 are connected together. The arrangement of the outlet main pipe is the same as that of the inlet main pipe 31; both the inlet and outlet main pipes of the inlet main pipe 31 are equipped with manual valves (not shown in the figure).

[0045] The principles and beneficial effects of the above technical solution:

[0046] The main inlet pipe 31, the main outlet pipe, and the connecting branch pipes 32 form a complete manifold system, allowing multiple hydrogen storage tanks 22 to be charged and discharged simultaneously. This manifold structure avoids the uneven pressure differential problem caused by traditional series connections, resulting in more balanced pressure distribution and more stable gas flow distribution for each hydrogen storage tank 22, thereby improving hydrogen utilization efficiency and system safety. It also facilitates unified inspection and maintenance, reducing layout confusion and leakage risks caused by complex pipeline intersections.

[0047] In this embodiment, the inlet end 221 or the outlet end is provided with a two-way interface 33; the end of the connecting branch pipe 32 away from the main inlet pipe 31 or the main outlet pipe is connected to the end of the two-way interface 33; and the two adjacent hydrogen storage tanks 22 are connected by a gas replenishment branch pipe 34.

[0048] The principles and beneficial effects of the above technical solution:

[0049] The two-way interface 33 and the gas supply branch pipe 34 form an auxiliary gas circulation path. When the pressure of a single tank is abnormal or the gas flow distribution is uneven, the gas supply branch pipe 34 can achieve automatic gas balancing, ensuring that the pressure in each hydrogen storage tank 22 is consistent, preventing overpressure or underpressure, thereby improving the overall safety, stability and reliability of the system.

[0050] In this embodiment, the outer side of the compartment 1 has an outlet facing the hydrogen storage system compartment 11; the outer side of the compartment 1 is hinged with a double door 6 that blocks the outlet.

[0051] The principles and beneficial effects of the above technical solution:

[0052] The double doors 6 are positioned directly opposite the hydrogen storage system compartment 11, allowing operators to directly enter and exit the operating area when inspecting or replacing hydrogen storage tanks 22 or pipeline components, thus improving maintenance efficiency.

[0053] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
