Description

Technical Field

[0001] This utility model relates to the field of fuel cells, and in particular to a fuel cell system transportation and fixing device. Background Technology

[0002] With the vigorous development of hydrogen energy in my country, its related industrial chain has gradually entered a stable phase. Fuel cell systems, as one of the core methods for utilizing hydrogen energy, are not only applied in automobiles, rail transportation, and ships, but also have some applications in the aerospace field. As a power generation device that converts chemical energy into electrical energy, the precision of fuel cell systems cannot tolerate bumps, impacts, or scratches during transportation. Fuel cell systems themselves contain many components, are heavy, and undergo rapid updates and iterations. How to transport fuel cell systems with high portability, high adaptability, and high safety has always been a challenge for the industry.

[0003] Taking the current transportation of fuel cell systems in China as an example, the main transportation method adopted by major companies is to fix the fuel cell system to a transport fixture before transporting it by means of a vehicle. Transport fixtures can be broadly divided into custom metal structures and custom wooden structures. Custom metal structure transport fixtures fix the fuel cell system to the metal transport fixture using bolts or pins. While this method greatly ensures the strength and stability of the fixed fuel cell system, it is highly specific and not universally applicable. That is, one type of transport fixture is used for one model of fuel cell system. Once the fuel cell system undergoes technological or structural updates, the transport fixtures for that batch will need to be remanufactured or even scrapped. Furthermore, after use, the transport fixtures themselves are bulky and inconvenient to disassemble and store due to their metal welding and other manufacturing processes.

[0004] Customized wooden transport securing devices can increase the diversity of transport securing devices to a certain extent and ensure the convenience of transport and storage after disassembly. However, due to the inherent characteristics of wooden structures, they cannot be reused multiple times, and wooden structures are easily affected by external factors such as rain and moisture, making them unsuitable for long-term storage.

[0005] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0006] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a transportation and fixing device that is simple in structure, ingenious in design, and rational in layout, enabling rapid disassembly and assembly and free combination to achieve perfect matching with fuel cell systems.

[0007] The technical solution of this utility model is: a fuel cell system transportation and fixing device, characterized in that: the device includes a cubic frame formed by connecting multiple square tubes 1, and blocking mechanisms are provided on the bottom surface and four sides of the frame.

[0008] The blocking mechanism is composed of a combination of two types of blocks: a fixed block 2 and an adjustable block 3.

[0009] The fixed stop bar 2 includes a first stop bar body 4, which is also designed as a square tube. Limiting clips 5 are respectively provided at both ends of the first stop bar body 4.

[0010] The adjustable stop bar 3 includes a second stop bar body 6 and a third stop bar body 7, both designed as square tubes. One end of the second stop bar body 6 is provided with a limit clamp 5, and the other end is fixedly connected to a bolt part 8. One end of the third stop bar body 7 is rotatably connected to a threaded sleeve 9 that matches the bolt part 8, and the other end is also provided with a limit clamp 5. Furthermore, a locking mechanism 10 that matches the threaded sleeve 9 is also provided on the third stop bar body 7.

[0011] The inner groove of the limiting clamp 5 matches the outer wall of the square tube 1, and a limiting bolt 11 is also inserted at the edge of the limiting clamp 5. The limiting bolt 11 is fixed to the square tube 1 by a nut 12.

[0012] The locking mechanism 10 includes two pairs of pawls, each pair consisting of two symmetrically distributed first pawls 13. The first pawls 13 are rotatably supported on the third stop body 7 via a pivot. The two first pawls 13 in the same pair are connected by a spring 14. The first pawls 13 are provided with a protrusion 15, which protrudes from the outer wall of the third stop body 7. The threaded sleeve 9 is provided with ratchet teeth 16, and the first pawls 13 are matched with the ratchet teeth 16.

[0013] The locking mechanism 10 includes four second pawls 17 with the same stopping direction. The second pawls 17 are rotatably supported on the third stop body 7 via a rotating shaft. The ends of all the second pawls 17 are rotatably connected to the drive ring 18. The drive ring 18 is movably sleeved on the outside of the third stop body 7. At the same time, two locking rods 19 are symmetrically arranged on the drive ring 18. The locking rods 19 are threadedly connected to the drive ring 18. A locking plate 20 is also provided at the inner end of the locking rod 19. The locking plate 20 can fit against the outer wall of the third stop body 7.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This type of fuel cell system transport and fixing device features a simple structure, ingenious design, and rational layout. It addresses the problems of traditional fixing devices used in fuel cell system transportation by offering a unique structural design. It includes a cubic frame with blocking mechanisms on multiple sides. These blocking mechanisms consist of a combination of two types of levers, with adjustable levers allowing for quick and convenient length adjustment. This enables the shape and installation position of the blocking mechanisms to be adjusted according to the specific structure of the fuel cell system, ensuring a stable fixation. Compared to traditional welding and bolted connections, this fixing device uses plug-in and clamping connections, allowing for quick and convenient assembly and disassembly. It is highly versatile, reusable, and effectively reduces costs. Furthermore, its simple manufacturing process and low production cost make it highly advantageous and suitable for widespread application in this field, with a promising market prospect.

[0024] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 8As shown: A fuel cell system transportation and fixing device includes a cubic frame formed by connecting multiple square tubes 1, with blocking mechanisms provided on the bottom surface and four sides of the frame 1.

[0025] The blocking mechanism is composed of a combination of two types of blocks: a fixed block 2 and an adjustable block 3.

[0026] The fixed stop bar 2 includes a first stop bar body 4, which is also designed as a square tube. Limiting clips 5 are respectively provided at both ends of the first stop bar body 4.

[0027] The adjustable stop bar 3 includes a second stop bar body 6 and a third stop bar body 7, both designed as square tubes. One end of the second stop bar body 6 is provided with a limit clamp 5, and the other end is fixedly connected to a bolt part 8. One end of the third stop bar body 7 is rotatably connected to a threaded sleeve 9 that matches the bolt part 8, and the other end is also provided with a limit clamp 5. Furthermore, a locking mechanism 10 that matches the threaded sleeve 9 is also provided on the third stop bar body 7.

[0028] The inner groove of the limiting clamp 5 matches the outer wall of the square tube 1, and a limiting bolt 11 is also inserted at the edge of the limiting clamp 5. The limiting bolt 11 is fixed to the square tube 1 by a nut 12.

[0029] The locking mechanism 10 includes two pairs of pawls, each pair consisting of two symmetrically distributed first pawls 13. The first pawls 13 are rotatably supported on the third stop body 7 via a pivot. The two first pawls 13 in the same pair are connected by a spring 14. The first pawls 13 are provided with a protrusion 15, which protrudes from the outer wall of the third stop body 7. The threaded sleeve 9 is provided with ratchet teeth 16, and the first pawls 13 are matched with the ratchet teeth 16.

[0030] The locking mechanism 10 includes four second pawls 17 with the same stopping direction. The second pawls 17 are rotatably supported on the third stop body 7 via a rotating shaft. The ends of all the second pawls 17 are rotatably connected to the drive ring 18. The drive ring 18 is movably sleeved on the outside of the third stop body 7. At the same time, two locking rods 19 are symmetrically arranged on the drive ring 18. The locking rods 19 are threadedly connected to the drive ring 18. A locking plate 20 is also provided at the inner end of the locking rod 19. The locking plate 20 can fit against the outer wall of the third stop body 7.

[0031] The working process of the fuel cell system transport and fixing device of this structural form is as follows: According to the specific size of the fuel cell system to be transported, a suitable square tube 1 is selected to construct a cubic frame. Then, multiple fixed baffles 2 and adjustable baffles 3 are used to construct blocking mechanisms on the bottom surface and four sides of the frame 1. The blocking mechanism on the bottom surface needs to play a supporting role, so the number of fixed baffles 2 and adjustable baffles 3 used can be appropriately increased. The blocking mechanisms on the four sides are T-shaped structures, which can play a limiting role.

[0032] When it is necessary to construct a blocking mechanism on the frame, first take a fixed stop bar 2 whose length matches the side opening of the frame, and fasten the slots of the limiting clamps 5 at both ends of the stop bar 2 onto the square tube 1 that forms the frame. Then, insert the limiting bolts 11 through the edge of the limiting clamps 5 and tighten the limiting bolts 11 with nuts 12. At this time, the two sides of the limiting clamps 5 will undergo slight deformation under the combined action of the nuts 12 and the ends of the limiting bolts 11, and clamp them onto the outer wall of the square tube 1, thereby realizing the connection of the fixed stop bar 2 on the frame 1.

[0033] Then take the adjustable stop bar 3, and fix the limiting clamps 5 at both ends of it onto the square tube 1 and the fixed stop bar 2 as described above. During operation, adjust the overall length of the adjustable stop bar 3 according to the actual situation and needs. After adjustment and connection with the square tube 1 and the fixed stop bar 2, lock the adjustable stop bar 3 using the locking mechanism 10, thus completing the construction of the blocking mechanism.

[0034] The adjustable stop lever 3 can have two structural forms. When the adjustable stop lever 3 is in embodiment one (e.g.) Figure 3 , Figure 4 As shown), in the initial state, the two first pawls 13 of the same pair of pawls are locked under the pull of the spring 14, that is, the first pawl 13 is stuck on the teeth of the ratchet 16, the ratchet 16 cannot rotate relative to the third stop body 7, and the threaded sleeve 9 fixedly connected to the ratchet 16 cannot rotate relative to the third stop body 7. At this time, the adjustable stop 3 cannot be adjusted in length. When it is necessary to adjust the length of the adjustable stop 3, pinch the protrusions 15 on the two first pawls 13 of the same pair of pawls with your fingers to drive the two first pawls 13 to swing. The first pawls 13 no longer contact the ratchet 16. If both pairs of pawls are operated in this way, the ratchet 16 is unlocked, and the threaded sleeve 9 is driven to rotate relative to the second stop body 6. During the rotation, the distance between the second stop body 6 and the third stop body 7 changes, thereby realizing the adjustment of the length of the adjustable stop 3. During the adjustment process, for convenience, a rubber ring can be fitted on the protrusions 15 of the same pair of pawls to keep the first pawl 13 in the unlocked state.

[0035] After the adjustment is completed, the rubber ring is removed. Under the action of the spring 14, the first pawl 13 returns to the locked state, and the adjustable lever 3 cannot change its length.

[0036] When the adjustable stop lever 3 is the same as in Embodiment 2 (e.g.) Figure 6 , Figure 7 As shown), in the initial state, because the locking rod 19, which is threaded onto the drive ring 18, has its locking plate 20 at its end against the outer wall of the third stop body 7, and the two are in surface contact, the drive ring 18 cannot rotate relative to the third stop body 7. That is, all the second pawls 17 are in the locked state, i.e., the second pawls 17 are stuck on the teeth of the ratchet 16, and the ratchet 16 cannot rotate relative to the third stop body 7. The threaded sleeve 9, which is fixedly connected to the ratchet 16, also cannot rotate relative to the third stop body 7. At this time, the adjustable stop 3 cannot be adjusted in length. It is necessary to adjust the length of the adjustable stop 3. When the locking rod 19 is rotated in the opposite direction, a certain gap is formed between the locking plate 20 and the outer wall of the third stop body 7. At this time, the drive ring 18 is unlocked in the circumferential direction. The drive ring 18 is rotated relative to the third stop body 7. When the drive ring 18 rotates, it will drive all the second pawls 17 to swing relative to the third stop body 7. The second pawls 17 no longer contact the ratchet 16. Then the threaded sleeve 9 is driven to rotate relative to the second stop body 6. During the rotation, the distance between the second stop body 6 and the third stop body 7 changes, thereby realizing the adjustment of the length of the adjustable stop 3.

[0037] After adjustment, rotate the drive ring 18 in the opposite direction to return the second pawl 17 to the locked state. Then tighten the locking rod 19 to make the locking plate 20 make tight contact with the outer wall of the third stop body 7 again. The second pawl 17 returns to the locked state, and the adjustable stop 3 cannot change its length.
