Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydrogen storage tank transportation, in particular to a hydrogen energy storage tank storage and transportation fixing device. BACKGROUND

[0002] As a zero-carbon clean energy, hydrogen energy is increasingly widely used in energy transformation, and its storage and transportation rely on high-pressure or low-temperature hydrogen energy storage tanks. The fixing reliability in the storage and transportation process directly determines the safety and efficiency of storage and transportation. Current hydrogen energy storage tank storage and transportation mostly uses traditional fixing methods, such as binding belt winding fixing, single metal clamp limiting, etc., which has significant technical defects:

[0003] 1. Insufficient fixing reliability: Traditional methods are mostly single-point or single-dimensional fixing, and the storage tank is prone to tilting and shifting due to transportation bumps, especially the lack of coordinated limiting of the front nozzle (including valves and other key components) and the tail of the high-pressure storage tank, which may cause tank nozzle deformation, sealing failure, and hydrogen leakage risk.

[0004] 2. Low operation efficiency and high labor cost: Existing fixing devices mostly rely on manual adjustment of the tightness of the binding belt or the position of the clamp, and multiple people are needed to cooperate during the loading and unloading process. Especially in batch storage and transportation scenarios, the operation steps are complicated and time-consuming, making it difficult to adapt to automated storage and transportation needs.

[0005] 3. Poor adaptability and easy damage to storage tanks: Most fixing clamps are customized for specific storage tank specifications, and need to be replaced when different diameter and length storage tanks are used, which has weak universality. Moreover, the clamps are mostly rigid metal structures that directly contact the outer wall of the storage tank, which may cause scratches and indentations on the outer wall of the storage tank due to loading and unloading or bumps.

DETAILED DESCRIPTION

[0035] In the application, the description such as "first", "second" and the like is only for the purpose of description, and is not intended to particularly indicate the order or sequence, nor to limit the application, which is merely to distinguish the protection assembly or operation described by the same technical terms, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features of each embodiment can be combined with each other, but it must be based on the realization of the person skilled in the art, and when the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the protection scope required by the application.

[0036] Example 1

[0037] Please refer to Figures 1-4The technical means provided by the present application comprises a storage and transportation box body 1, a limiting front baffle 2 is installed on the front side of the storage and transportation box body 1, a plurality of groups of placement bottom plates 3 are installed in the storage and transportation box body 1, a plurality of groups of tank front mouth fixing assemblies 4 and tank tail fixing assemblies 5 are arranged in front and back on the placement bottom plates 3, and each group of tank front mouth fixing assemblies 4 and tank tail fixing assemblies 5 are located on the same horizontal line and are used in cooperation, the tank front mouth fixing assembly 4 is used for placing a tank front mouth 8, and the tank tail fixing assembly 5 is used for placing a tank tail 9.

[0038] Preferably, a clamping plug 7 is formed on the frame of the limiting front baffle 2 and extends, a clamping groove corresponding to the clamping plug 7 is formed on the inner wall of the storage and transportation box body 1, and a plurality of groups of through holes 6 are formed on the limiting front baffle 2.

[0039] The working principle and beneficial effects of the above scheme are as follows: in use, after the limiting front baffle 2 is disassembled, a plurality of groups of hydrogen energy storage tanks are installed on the tank front mouth fixing assemblies 4 and the tank tail fixing assemblies 5 arranged on the placement bottom plates 3, and when installing, the tank tail 9 needs to be placed on the tank tail fixing assembly 5 and stabilized first, and then the tank front mouth 8 is fixed by using the tank front mouth fixing assembly 4, and when disassembling, the tank front mouth 8 needs to be loosened first, and then the tank tail 9 is released by the tank tail fixing assembly 5.

[0040] After the hydrogen energy storage tank is fixed by the tank front mouth fixing assembly 4 and the tank tail fixing assembly 5, the limiting front baffle 2 is inserted into the clamping groove formed on the inner wall of the storage and transportation box body 1 through the clamping plug 7, each through hole 6 corresponds to a group of hydrogen energy storage tanks, and the tank front mouth 8 of the hydrogen energy storage tank extends out of the through hole 6 to facilitate observation of the hydrogen energy storage tank at any time.

[0041] The front mouth fixing assembly, the tail fixing assembly and the limiting front baffle of the device are relatively independent modular structures, and each component is installed on the storage and transportation box body or the placement bottom plate by a detachable connection mode such as a bolt and a supporting leg: when a single component is damaged, only the corresponding module needs to be replaced, without the need for overall maintenance, thereby reducing maintenance costs; meanwhile, the fixed assembly that is suitable for different storage and transportation requirements (such as the capacity of the storage tank and the pressure grade) can be replaced, thereby improving the upgradability of the device.

[0042] The clamping claws of the tank front mouth fixing assembly are rotationally connected with the linkage bent rod through the first connecting rod, and the clamping claws can flexibly move around the connecting point, without the need to replace the clamping claws to adapt to tank front mouths of different diameters and different shapes (such as cylindrical front mouth structures and front mouth structures with slight taper), thereby breaking the limitation of the traditional fixing device “one specification one adaptation”, and improving the versatility of the device for different types of hydrogen energy storage tanks.

[0043] The device forms a "front mouth-tail" horizontal corresponding matching through the tank front mouth fixing assembly 4 and the tank tail fixing assembly 5 arranged on the bottom plate 3 in the storage and transportation box body 1, realizes the basic two-point positioning of the hydrogen energy storage tank, and ensures the stable placement of the storage tank; the limiting front baffle 2 is detachably connected with the inner wall clamping groove of the storage and transportation box body 1 through the clamping plug 7, which is convenient for storage tank loading and unloading operation, the through hole 6 opened can make the tank front mouth 8 extend out, which is convenient for real-time observation of the state of the storage tank, at the same time, the limiting front baffle forms lateral limiting to the front end of the storage tank, and the basic storage and transportation guarantee structure of "fixed assembly + baffle protection" is constructed, and the independent tank front mouth fixing assembly and the tank tail fixing assembly form "two-point positioning", and the two assemblies are horizontally corresponding arranged along the arrangement bottom plate, which ensures that the hydrogen energy storage tank is fixed in a horizontal posture, avoids the inclination or movement caused by the failure of a single fixed point during storage and transportation; at the same time, the limiting front baffle is fixed in the storage and transportation box body through the "clamping plug-clamping groove" cooperation, which further forms lateral limiting to the front end of the storage tank, and constructs the double protection of "assembly fixing + baffle protection".

[0044] Embodiment 2

[0045] On the basis of embodiment 1, please refer to Figure 1 、 Figure 2 、 Figures 5-8 , the tank front mouth fixing assembly 4 is composed of inclined strut 10, linkage bent rod 11, claw assembly 12 and limiting vertical column assembly 13, two groups of inclined struts 10 are symmetrically arranged on the top front side of the arrangement bottom plate 3, and one group of linkage bent rods 11 is arranged on each group of inclined struts 10, the claw assembly 12 is arranged on each group of linkage bent rods 11, and the limiting vertical column assembly 13 is arranged between the two groups of inclined struts 10.

[0046] Preferably, a driving cylinder one 25 is arranged between the bottoms of the two groups of linkage bent rods 11, and the two ends of the driving cylinder one 25 are movably connected with the bottoms of the two groups of linkage bent rods 11, respectively. The linkage bent rod 11 is connected with the limiting vertical column assembly 13 through the limiting connecting rod two 47.

[0047] Preferably, the claw assembly 12 comprises a tank claw 16, the tank claw 16 is arranged on the fixed plate one 15 through bolts, a connecting support one 17 is fixedly arranged on the side of the fixed plate one 15 away from the tank claw 16, one end of the first connecting rod 14 is rotatably connected with the connecting support one 17, and the other end of the first connecting rod 14 is rotatably connected with the linkage bent rod 11.

[0048] Preferably, the limiting column assembly 13 comprises a limiting column 18, a support base 20 is fixedly arranged at the bottom of the limiting column 18, and the support base 20 is arranged on the placing bottom plate 3 through a plurality of groups of supporting legs 24, a placing plate 21 is fixedly arranged at the top of the limiting column 18, a guide sleeve ring 19 is movably sleeved on the outer wall of the limiting column 18, and two groups of connecting seats two 22 are symmetrically arranged on the outer wall of the guide sleeve ring 19, one end of a second connecting rod 23 is rotatably connected with the connecting seat two 22, and the other end of the second connecting rod 23 is rotatably connected with the limiting column assembly 13.

[0049] The working principle and beneficial effects of the above scheme are that the tank front mouth 8 is placed on the placing plate 21 at the same time, and the driving cylinder one 25 is started, and since the driving cylinder one 25 is suspended at the top of the placing bottom plate 3, the placing bottom plate 3 is extended to synchronously push the bottoms of the two groups of linkage bending rods 11 to move in directions away from each other. At this time, the linkage bending rods 11 pull the guide sleeve ring 19 to slide along the limiting column 18 through the second connecting rod 23, so as to play a guiding and limiting role on the movement of the linkage bending rods 11, and since the linkage bending rods 11 have a rotation point around the inclined struts 10 in the middle and upper parts, the tops of the linkage bending rods 11 move in directions close to each other until the two groups of tank grippers 16 abut against the outer wall of the tank front mouth 8, and the two groups of tank grippers 16 and the placing plate 21 form a triangular fastening, so as to limit the hydrogen energy storage tank.

[0050] Since the tank grippers 16 are rotatably connected with the linkage bending rods 11 through the first connecting rods 14, the tank grippers 16 can be arbitrarily moved to facilitate the limitation of the hydrogen energy storage tank, and the placing plate 21 can be fixedly arranged on the tank front mouth 8 under the cooperation of the two groups of tank grippers 16.

[0051] In the tank front mouth fixing assembly, when the driving cylinder one drives the linkage bending rods to drive the gripper assembly to close, the two groups of tank grippers and the placing plate form a triangular fastening structure (the triangular structure has mechanical stability and can effectively disperse the stress of the storage tank), so as to realize the composite fixing of the tank front mouth in the form of “encircling + supporting” and avoid the deformation of the front mouth due to the stress concentration;

[0052] The tank tail fixing assembly drives the guide push block through the driving cylinder two, drives the fixing clamp arm to rotate around the driving shaft through the inclined surface transmission, and makes the two groups of rubber pressure wheels one abut against the outer wall of the tank tail, cooperates with the top support of the rubber pressure wheel three, forms a “side clamping + top supporting” tail fixing structure, and ensures that the tail of the storage tank has no radial displacement space.

[0053] The guide sleeve ring of the front mouth fixing assembly slides along the limiting column to accurately guide the movement track of the linkage bending rod, and prevents the fixing from being invalid due to deviation when the gripper is closed;

[0054] The guide groove of the tail fixing assembly limits the sliding direction of the guide push block, and the limit link transversely limits the movement of the driving block, so as to ensure stable force transmission in the mechanical linkage process and avoid mispositioning of the fixed clamping arm.

[0055] Embodiment 3

[0056] On the basis of any one of embodiments 1-2, please refer to Figure 1 、 Figure 3 、 Figures 9-12 The tail fixing assembly 5 of the tank body includes a driving block 26 and a guide push block 46. A guide groove 45 is formed in the top rear side of the installation base plate 3. The guide push block 46 is slidably arranged in the guide groove 45. Two groups of fixed vertical plates 27 are fixedly arranged on the top of the frame of the guide groove 45, and the two groups of fixed vertical plates 27 are connected by a limit link 36. The driving block 26 is sleeved on the limit link 36.

[0057] Preferably, the driving block 26 is hollow. The front and rear sides of the driving block 26 are provided with avoiding grooves 37, and the limit link 36 is movably arranged through the avoiding grooves 37. The left and right sides of the driving block 26 are provided with inclined surfaces. Two groups of fixed clamping arms 30 are symmetrically arranged on the left and right sides of the driving block 26. A rubber pressure wheel 43 is arranged on the top of the driving block 26. A support inclined surface 42 is arranged on the bottom of the driving block 26.

[0058] Preferably, the fixed clamping arm 30 is provided with a rubber pressure wheel 31 at one end, a rubber pressure wheel 40 at the other end, and a driving shaft 38 at the bending point. The support rod 32 is rotatably connected with the driving shaft 38 at one end, and is fixedly provided with a support plate 33 at the other end. The fixed rod 34 is fixedly connected with the support plate 33 at one end, and is fixedly provided with a triangular fixing frame 35 at the other end. The triangular fixing frame 35 is fixedly arranged on the top of the frame of the guide groove 45.

[0059] Preferably, the two groups of rubber pressure wheels 40 are respectively in abutment with the left and right sides of the driving block 26. A return spring 41 is arranged in the driving block 26, and the two ends of the return spring 41 extend out of the driving block 26 and are connected with the driving shafts of the rubber pressure wheels 40. The top of the guide push block 46 is provided with a guide inclined surface 44 which is in conformity with the support inclined surface 42. The driving cylinder 29 is fixedly arranged in the guide groove 45, and the output end of the driving cylinder 29 is fixedly provided with a guide push plate 28. The guide push plate 28 is fixedly connected with the driving block 26.

[0060] The working principle and beneficial effects of the above scheme are: the tank tail 9 is placed into the rubber pressing wheel three 43, and the driving cylinder two 29 is started, the driving cylinder two 29 pushes the guide push block 46 to move towards the bottom of the driving block 26, and at the same time, the guide push plate 28 moves along the guide groove 45, until the supporting slope 42 contacts with the guide slope 44, and the guide push block 46 continues to move to lift the driving block 26, due to the setting of the left and right inclined surfaces of the guide push block 46, the fixed clamping arm 30 with the rubber pressing wheel two 40 is stretched away from each other when the guide push block 46 moves upward, and the reset spring 41 is stretched, at this time, since the fixed clamping arm 30 rotates around the driving shaft one 38, the top of the fixed clamping arm 30 moves towards each other, until the two groups of rubber pressing wheels one 31 abut against the outer wall of the tank tail 9, so as to complete the fixation of the tank tail 9.

[0061] When disassembling the hydrogen energy storage tank, only the driving cylinder two 29 is started to drive the guide push block 46 to reset, and the driving block 26 is lowered under the action of gravity, so that the reset spring 41 pulls the fixed clamping arm 30 to reset, at this time, the rubber pressing wheel one 31 on the top of the fixed clamping arm 30 is opened, and the tank tail 9 is loosened.

[0062] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
