Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen storage tank transportation, and particularly relates to a hydrogen storage tank transportation device. Background Art

[0002] As a clean, efficient and renewable energy source, hydrogen has been widely used in recent years in fields such as fuel cells and chemical production. In order to achieve safe storage and transportation of hydrogen, high-pressure containers (such as hydrogen tanks) are usually used to seal hydrogen, and corresponding fixing and protection structures are used to reduce the impact of collisions, bumps or other external forces on the storage tank during transportation. However, the existing hydrogen tank transportation devices still have the following deficiencies during use:

[0003] 1. Lack of convenient and efficient fixing means: When placing the hydrogen tank onto the transportation device, without a suitable guiding and buffering structure, operators often need to use a large amount of force to accurately and safely place the tank in place, and it is also quite laborious to remove the hydrogen tank after transportation, making it inconvenient to achieve rapid loading and unloading.

[0004] 2. The protection stability needs to be improved: During the driving of transportation tools such as automobiles, if there are situations such as collisions, bumps or sudden braking, the impact force on the hydrogen tank may be relatively large. If the transportation device itself has insufficient support, buffering and anti-collision capabilities for the tank, there is a risk of the storage tank moving, being damaged or leaking, making it difficult to meet the requirements of high-safety transportation.

[0005] 3. The fixing and buffering structures are relatively scattered: Some existing designs only set simple restraint structures on the fixing frame or bracket, and do not set a perfect buffering component in the support sleeve. As a result, when the hydrogen tank is subjected to external force impact, it is easy to have a direct hard collision between the tank body and the bracket, lacking sufficient buffering protection. In addition, the tank body is also prone to shaking when the vehicle vibrates or turns, thus posing a safety hazard. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a hydrogen storage tank transportation device, which can achieve improving the convenience of placing and removing the hydrogen tank by adding corresponding protection and support structures, and further enhancing the stability and safety during transportation.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A hydrogen storage tank transportation device with a protection structure, including an outer frame, a hydrogen tank and the loading area of a transportation vehicle, further including two upper support frames and a plurality of uniformly distributed protection frames detachably installed on the support frames, and the hydrogen tank is vertically inserted inside the two corresponding upper and lower protection frames;

[0009] The protective frame automatically clamps the hydrogen tank horizontally and provides anti-collision buffer protection, and guides the movement of the hydrogen tank vertically.

[0010] A buffer pad for supporting the lower end of the hydrogen tank is installed at the inner bottom of the outer frame, and a blocking net covering the upper end of the hydrogen tank is fixed at the upper end of the outer frame.

[0011] Furthermore, evenly arranged installation cavities are provided inside the support frame. Card slots are opened on the four side walls inside the installation cavities. At the position corresponding to the card slots at the edge of the upper port of the installation cavity, a baffle is provided. The baffle is rotatably installed on the support frame through a rotating column at one end of it.

[0012] Furthermore, the protective frame includes a support sleeve detachably installed in the installation cavity. A plurality of evenly distributed buffer members are detachably and washably installed inside the support sleeve. The buffer members elastically abut against the hydrogen tank and guide the hydrogen tank during up and down movement.

[0013] Furthermore, a plurality of card boards stuck in the card slots are fixed on the outer side of the support sleeve, and a plurality of slots for installing the buffer members are evenly opened on the inner side surface of the support sleeve.

[0014] Furthermore, the buffer member includes an insertion block inserted into the slot and a roller. A rotating bracket for rotatably installing the roller is fixed on one side of the insertion block. A rubber inner ring is fixedly sleeved on the outer side of the roller. A rubber outer ring is arranged on the outer side of the rubber inner ring. And the rubber inner ring and the rubber outer ring are fixedly connected by a plurality of evenly distributed support columns.

[0015] Furthermore, the buffer pad includes an airbag pad. Airbag columns protruding are arranged at the positions corresponding to the hydrogen tank on the upper surface of the airbag pad.

[0016] Furthermore, the outer frame includes a bottom plate and a square frame arranged above the bottom plate. Columns fixedly connected to the square frame are fixed at the positions near the four corners on the upper surface of the bottom plate. And a placement groove is opened on the upper surface of the bottom plate. A connecting plate connected and fixed to the support frame is fixed on the column. A plurality of connecting rings for bundling and fixing the edge of the blocking net are fixed inside the square frame.

[0017] Furthermore, universal wheels are fixed at the positions near the four corners on the lower surface of the bottom plate, and support mechanisms capable of supporting the ground downward are installed at both the left and right ends of the bottom plate.

[0018] Furthermore, the support mechanism includes a fixed sleeve fixed on the bottom plate and a support plate vertically penetrating the fixed sleeve. A horizontal cushion plate is fixed at the lower end of the support plate. Anti-slip convex points are evenly distributed on the lower surface of the cushion plate. A plurality of locking screws are threadedly installed on the side surface of the fixed sleeve.

[0019] Furthermore, two positioning columns penetrating the backing plate are fixed on the surface of the car body. Grooves are formed on the opposite sides of the two positioning columns. A locking plate is arranged on the upper surface of the backing plate. The two ends of the locking plate are respectively stuck in the grooves on the two positioning columns, and a tightening screw is installed at the middle part of the locking plate in a threaded manner.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] By arranging an installation cavity and a detachably installed support sleeve on the inner side of the support frame, and installing a plurality of uniformly distributed buffer members in the support sleeve, when the hydrogen tank is placed and taken out, the sliding guide formed by the roller and the rubber outer ring significantly reduces the operation difficulty, making the installation and disassembly during transportation easier and more labor-saving; at the same time, after the hydrogen tank is placed, through the bundling cooperation between the edge of the blocking net and the connecting ring, the hydrogen tank can also be stably supported in the vertical direction, meeting the requirements of rapid loading and unloading and safety restraint.

[0022] By arranging elastic buffer members on the inner side of the support sleeve and adopting a double-buffer form of an airbag pad and an airbag column at the bottom, the external impact force can be absorbed by the rubber outer ring and the support column under collision or bump conditions, and at the same time, the airbag column provides anti-seismic and shock-absorbing functions for the hydrogen tank in the vertical direction, effectively avoiding the shaking or damage of the tank body in a high-intensity vibration environment; in addition, the support mechanism of the outer frame and the car body are integrally stabilized through the matching of the positioning column and the locking plate, and can maintain good stability during vehicle turning or sudden braking, reducing the risk of hydrogen tank displacement. By forming a tight fit between the support sleeve, the installation cavity, the card slot and the card plate, the buffer components are concentrated on the protective frame and the buffer pad, and together with the square frame, the upright column, the blocking net and the support mechanism, an integrated transportation protection system is formed, which can not only firmly fix the hydrogen tank in the horizontal and vertical directions, but also cope with different forms of impact or bump through a multi-stage buffer method, thus generally improving the reliability and safety of the transportation equipment.

[0035] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0036] Embodiment 1,

[0037] As Figure 1As shown in the figure, a hydrogen storage tank transportation device includes an outer frame 2, a hydrogen tank 5, and the carriage 6 of a transport vehicle. It also includes two upper support frames 3 and a plurality of evenly distributed protective frames 4 detachably installed on the support frames 3. The hydrogen tank 5 is vertically inserted inside the two corresponding protective frames 4 above and below. The outer frame 2 is made of 6061 aluminum alloy profiles and its surface is treated with hot-dip zinc anti-corrosion to improve durability in high-humidity and salt-fog environments. The hydrogen tank 5 complies with the GB / T 5099-2014 standard and is coated with a high-temperature resistant fluorocarbon coating on its outer wall to reduce friction loss and oxidation corrosion. The two upper support frames 3 are made of Q235 carbon structural steel and their surface is enhanced with anti-rust performance through polyester powder coating technology. When the protective frame 4 cooperates with the hydrogen tank 5, the buffer member 42 provides multi-directional collision buffering and clamping support during the bumping, sudden braking, or steering of the vehicle during transportation, and the combination of the blocking net further improves the transportation safety of the hydrogen tank 5.

[0038] The protective frame 4 automatically clamps and provides anti-collision buffer protection for the hydrogen tank 5 in the horizontal direction, and the protective frame 4 guides the movement of the hydrogen tank 5 in the vertical direction. When the protective frame 4 is installed, it is fixed through the cooperation between the clamping plate 411 and the clamping groove 32 and can be adjusted in position according to hydrogen tanks 5 of different sizes. A plurality of buffer members 42 act on the outer surface of the hydrogen tank 5 simultaneously to disperse the collision impact force and prevent the storage tank from shaking or colliding during transportation. The combination of the support sleeve 41 and the blocking net forms a fixed structure that echoes each other vertically and horizontally to ensure that the hydrogen tank 5 does not produce obvious displacement when the vehicle is driving at high speed or turning.

[0039] A buffer pad 1 for supporting the lower end of the hydrogen tank 5 is installed at the inner bottom of the outer frame 2, and a blocking net covering the upper end of the hydrogen tank 5 is fixed at the upper end of the outer frame 2. The buffer pad 1 is made of EPDM rubber material and filled with a flame-retardant inert gas that complies with the HG / T2198-2016 standard to improve the safety factor in high-temperature environments. The blocking net is woven from 304 stainless steel wires to form a mesh structure with a pore size of 10mm×10mm and is fixed with a metal retaining ring on the outer circle. Combined with the connecting ring 26, it can be tightly fixed to the upper end after the hydrogen tank 5 is placed.

The rubber inner ring 425 and the rubber outer ring 423 are fixedly connected by a plurality of uniformly distributed support columns 426; the insertion block 421 is made of polyurethane material with a Shore A hardness of 70 and a high-wear-resistant coating is applied on the outer surface to extend the service life; the rotating bracket 422 is made of galvanized steel plate with a thickness of 3 mm and is connected to the insertion block 421 by a locknut; the diameter of the roller 424 is set to 40 mm and alloy steel bearings are used to ensure smooth operation under long-term high-speed rotation; both the rubber inner ring 425 and the rubber outer ring 423 are made of neoprene. The support columns 426 have a diameter of 5 mm and are evenly distributed between the inner and outer rings to absorb the impact energy during collision and ensure the safety and stability of the hydrogen tank 5 under bumpy road conditions.

[0044] As Figure 6 shown, the buffer pad 1 includes an airbag pad 110. At the positions corresponding to the hydrogen tank 5 on the upper surface of the airbag pad 110, raised airbag columns 120 are provided; the airbag pad 110 is made of EPDM material and filled with high-purity nitrogen inside to meet the requirements of flame retardancy and antioxidant, and at the same time avoid the risk of bursting when the external environment temperature is relatively high; the height of the airbag columns 120 is set to 30 mm and they are evenly distributed on the surface of the airbag pad 110 at intervals of 10 mm, so as to increase the buffer space when the hydrogen tank 5 is placed at the bottom and effectively disperse the impact force under multiple impacts.

[0045] As Figure 7 shown, the outer frame 2 includes a bottom plate 21 and a square frame 25 arranged above the bottom plate 21. Columns 23 fixedly connected to the square frame 25 are fixed at the upper surface of the bottom plate 21 near the four corners. A placement groove 27 is formed on the upper surface of the bottom plate 21. A connecting plate 24 fixedly connected to the support frame 3 is fixed on the column 23. A plurality of connecting rings 26 for bundling and fixing the edge of the blocking net are fixed inside the square frame 25; the bottom plate 21 is made of Q235 steel plate with a thickness of 8 mm and is spray-coated with double-sided anti-corrosion to extend the service life when stored outdoors; the size of the column 23 is 40 mm×40 mm and reinforcing rib plates are added inside to improve the overall stiffness; the connecting plate 24 and the support frame 3 are fastened by M10 high-strength bolts to ensure no displacement when subjected to impact; the square frame 25 is welded by 304 stainless steel round tubes and the connecting rings 26 are evenly distributed to fix the blocking net on the upper part of the hydrogen tank 5.

[0047] As Figure 8 shown, the support mechanism 28 includes a fixed sleeve 282 fixed on the bottom plate 21 and a support plate 281 vertically penetrating the fixed sleeve 282. A horizontal backing plate 284 is fixed at the lower end of the support plate 281, and uniformly distributed anti-slip bumps 285 are fixed on the lower surface of the backing plate 284.

[0048] Embodiment 2. For the device provided by the embodiment of the present invention, the implementation principle and the technical effects generated are the same as those of Embodiment 1. For a brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding content in Embodiment 1; in Embodiment 2, when transporting the high-pressure hydrogen tank 5, the elastic buffer design of the protective frame 4 and the support sleeve 41 is also adopted, and rubber shock pads are added at the connection part between the outer frame 2 and the support frame 3 to cope with the large bumps in complex road conditions; in the actual application of installing the hydrogen tank 5 multiple times, the combined buffer of the airbag pad 110 and the airbag column 120 further reduces the impact between the tank body and the bottom plate 21, and the outer frame 2 is firmly fixed under the cooperation of the lock plate 286 and the positioning column 61.

[0049] As Figure 9 and Figure 10As shown in the figure, two positioning posts 61 penetrating the backing plate 284 are fixed on the surface of the carriage 6. Grooves are formed on one side of the two positioning posts 61 facing each other. A lock plate 286 is arranged on the upper surface of the backing plate 284.

[0050] Embodiment 3:

[0051] This embodiment mainly aims to improve the problem of the lack of convenient and efficient fixing means for hydrogen tanks mentioned in the background technology. By arranging an installation cavity matching the outer diameter of the hydrogen tank on the inner side of the support frame and detachably installing a support sleeve, stable sliding guidance can be obtained when the operator inserts the hydrogen tank into the support sleeve. The outer wall of the support sleeve is formed by extrusion of 6063-T5 aluminum alloy, and the surface is treated by anodic oxidation to improve the scratch resistance and corrosion resistance. When a plurality of buffer members are evenly installed on the inner wall, roller and rubber outer ring are used to provide sliding fit. The roller uses a alloy steel bearing with a diameter of 40mm, and the outer part is provided with a rubber outer ring made of chloroprene rubber. The rubber outer ring and the inner ring are evenly connected by support columns with a diameter of 5mm, realizing rolling friction reduction and reliable clamping during the insertion and removal of the hydrogen tank. The support sleeve is loaded and unloaded by the interference fit of the external clamping plate and the clamping groove, and a handle is added to the support sleeve for quick grasping during disassembly. After the hydrogen tank is inserted and placed in place, a blocking net is used to tie and fix it at the upper end through a connecting ring made of 304 stainless steel, realizing the stable constraint of the hydrogen tank in the vertical direction, thereby ensuring safety and convenience while enabling quick installation and disassembly.

[0052] Embodiment 4:

[0053] This embodiment mainly focuses on the optimization design for the lack of effective protection of the hydrogen tank during vehicle driving. By adopting a double buffer structure to further enhance the shock absorption and anti-impact performance of the hydrogen tank. First, a plurality of buffer members are arranged on the inner side of the support sleeve. The buffer members are preferably made of nitrile rubber or polyurethane high-elastic materials, and the density can be between 0.8g / cm 3 to 1.1g / cm 3The hardness of the airbag is 70 Shore A, which can absorb horizontal collision energy when the vehicle is bumpy or in emergency braking. Secondly, an airbag cushion made of EPDM material is installed at the bottom. The airbag cushion is filled with high-purity nitrogen to prevent the risk of explosion in high temperature environment. The airbag column with a height of 30mm is used on the surface of the airbag cushion for vertical vibration reduction. When the vehicle is subjected to large bumps, the airbag column and the support sleeve buffer cooperate with each other to achieve multi-directional buffering. A support mechanism is set at the bottom of the outer frame and is firmly installed through the positioning column and the lock plate. The positioning column can be made of 45 steel after quenching and tempering, with a diameter of 20mm to increase the bending resistance. The lock plate is stamped and formed with 304 stainless steel plate and the surface is sandblasted to enhance the wear resistance, further improving the stability and reliability of the hydrogen tank during driving.

[0054] Embodiment 5:

[0055] This embodiment focuses on solving the problem of relatively scattered fixing and buffering structures in the prior art, and adopts a method of integrating multiple protection means into an overall frame to form a comprehensive system that can protect from top to bottom and from left to right. By forming a tight fit between the support sleeve, the installation cavity, the card slot and the card plate, all buffer parts are centrally arranged on the protective frame and the bottom buffer pad to reduce the risk of loosening caused by the dispersion of parts. The support sleeve can be rotatably matched with the baffle on the support frame to make disassembly and assembly easier; the outer frame uses 8mm thick Q235 steel plate to make the bottom plate, and the periphery is supported by 40mm×40mm square tube columns welded and reinforced with double-layer weather-resistant paint. The square frame and the barrier net form the upper fixed end. The barrier net material is preferably woven with 304 stainless steel wire, and the aperture is not greater than 10mm to effectively prevent the hydrogen tank from displacing in any direction. Before vehicle transportation, the pads and anti-slip bumps in the support mechanism can be used to fit closely to the ground, and the locking screws can be used to prevent the frame from shaking. When the outer frame is moved to the truck bed, the positioning columns and locking plates are used to achieve seamless docking with the truck bed. The support sleeve and buffer parts jointly bear the main force absorption during collision and vibration, significantly improving the buffering performance and safety of the overall transportation equipment in the horizontal and vertical directions.

[0056] The working principle of the present invention is as follows: When transporting the hydrogen gas cylinder 5, the support sleeves 41 are installed one by one in the installation cavity 31 of the support frame 3, and then the hydrogen gas cylinders 5 are inserted into the inner sides of the support sleeves 41 one by one. At this time, the buffer members 42 in the support sleeves 41 use the rolling rollers 424 and the rubber outer rings 423 to perform sliding guidance during the installation of the hydrogen gas cylinders 5, making it easier and more convenient to place, clamp, and remove the hydrogen gas cylinders 5 during transportation. After the hydrogen gas cylinders 5 are placed, finally, the edge of the blocking net is tied to the connecting ring 26 in the square frame 25 to press the hydrogen gas cylinders 5 downward, and then the outer frame 2 is pushed to the inside of the truck bed 6. At this time, the locking screw 283 is loosened, and the support plate 281 is pressed downward so that the cushion plate 284 and the anti-slip bumps 285 touch the ground for support, and then the locking screw 283 is screwed to fix the support plate 281, thus completing the fixed support of the outer frame 2;

[0057] When the vehicle is in transportation, the multiple buffer members 42 in the support sleeves 41 clamp the hydrogen gas cylinders 5 by the elastic deformation of the rubber outer rings 423 and the support columns 426. When there is a vehicle collision or jolt, the rubber outer rings 423 and the support columns 426 can use elastic deformation for buffer protection. At the same time, when the vehicle jolts, the airbag columns 120 are used to buffer and protect the hydrogen gas cylinders 5, so as to better complete the protection of the hydrogen gas cylinders 5 during transportation;

[0058] When installing the support sleeve 41, the support sleeve 41 is placed in the installation cavity 31, and the clamping plate 411 is stuck inside the card slot 32, and then the baffle 33 is rotated to block above the clamping plate 411, thus completing the installation and fixation of the support sleeve 41. The support sleeve 41 and the clamping plate 411 also further improve the anti-collision protection for the transportation of the hydrogen gas cylinders 5;

[0059] When the outer frame 2 moves to the inside of the truck bed 6, at this time, the locking screw 283 is loosened, and the support plate 281 is pressed downward so that the cushion plate 284 is sleeved on the positioning column 61. Then, the lock plate 286 is installed between two corresponding positioning columns 61 and the edge of the lock plate 286 is stuck in the groove on the positioning column 61. Then, the tightening screw 287 is screwed to tighten against the cushion plate 284 to lock and fix the lock plate 286, thus completing the stabilization of the outer frame 2 in the truck bed 6, and further improving the transportation protection of the hydrogen gas cylinders 5.

[0060] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
