Description

Technical Field

[0001] This utility model relates to the field of hydrogen refueling stations, and in particular to an auxiliary device for hydrogen refueling operations. Background Technology

[0002] Renewable energy sources such as solar, wind, and tidal power are environmentally friendly and inexhaustible, and will inevitably become the mainstay of future energy. However, the power output of their power generation systems is intermittent and random, unable to respond synchronously to electricity loads and thus failing to meet people's electricity needs. Hydrogen energy can be converted from renewable energy through water electrolysis technology. On the one hand, it can be combined with fuel cell power generation technology to achieve peak shaving and energy storage of renewable energy. On the other hand, hydrogen energy can be utilized through multiple pathways such as direct sales, hydrogen fuel cell transportation, and blending hydrogen with natural gas. Hydrogen refueling stations, as a crucial infrastructure for obtaining hydrogen sources for hydrogen fuel cell vehicles and other hydrogen energy utilization devices, have experienced rapid development globally.

[0003] Currently, hydrogen refueling operations at hydrogen refueling stations rely solely on refueling operators manually lifting the nozzle to refuel vehicles. The daily refueling volume is 1000 kg, requiring refueling 20-25 vehicles and inserting and removing the nozzle approximately 50 times. Each operation requires precise alignment with the 1.2-meter-high refueling nozzle and locking technique, placing high demands on the operators' skills and physical strength. To reduce the workload of refueling operators and address the difficulty in aligning the nozzle, we propose a hydrogen refueling operation auxiliary device to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for hydrogenation operations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydrogen refueling auxiliary device includes two first bearing seats and a second bearing seat. The inner walls of the first bearing seats and the second bearing seats are jointly engaged with a first optical axis. A transition seat is fixedly connected to the left side of the first optical axis. A second optical axis is engaged with the left side of the transition seat. A linear box-type slider is slidably connected to the outer surface of the second optical axis. A hinge seat is fixedly connected to the bottom surface of the linear box-type slider. A connecting block is hinged to the inner wall of the hinge seat. A spring balancer is fixedly connected to the bottom surface of the connecting block. A bracket is fixedly connected to the bottom surface of the spring balancer. A hydrogen refueling gun is engaged with the inner wall of the bracket. A hose is fixedly connected to the right side of the hydrogen refueling gun.

[0007] In a further embodiment, the outer surface of the first bearing housing and the outer surface of the second bearing housing are both threadedly connected to two fixing pins.

[0008] In a further embodiment, each of the fixing pins is fitted with an anti-slip pad on its outer surface, the anti-slip pad being made of rubber.

[0009] In a further embodiment, a floodlight warning sticker is provided on the front side of the first optical axis, and the back side of the floodlight warning sticker is fixedly connected to the front side of the first optical axis.

[0010] In a further embodiment, a protective sleeve is fitted over the outer surface of the hose, and the left side of the protective sleeve is fixedly connected to the right side of the hydrogen refueling gun.

[0011] In a further embodiment, a first hinge seat is fixedly connected to the left side of the first optical axis, and a transition block is fixedly connected to the right side of the second optical axis. A second hinge seat is fixedly connected to the upper surface of the transition block, and a support rod is hinged together with the inner wall of the second hinge seat and the inner wall of the first hinge seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device connects two optical axes via a first hinge, an adapter block, a second hinge, and a support rod, effectively enhancing the stability of the overall structure. It can maintain good performance under various complex working conditions and is highly adaptable. It can flexibly adjust the spring torque according to the weight of the hydrogen refueling nozzle, achieving stress extension and forceless retraction functions. It precisely matches the needs of different hydrogen refueling nozzles, ensuring smooth and efficient operation. At the same time, it rotates flexibly, freely rotating 360° to the corresponding refueling port, regardless of the parking position of the refueling vehicle. This greatly improves the flexibility and convenience of hydrogen refueling operations, effectively increasing hydrogen refueling efficiency, reducing vehicle waiting time, optimizing the hydrogen refueling process, and reducing the difficulty and intensity of manual operation.
