Description

Technical Field

[0001] The present application relates to the field of all-vanadium redox flow batteries, and in particular to an installation tool for vanadium redox flow batteries. Background Art

[0002] The vanadium flow battery is a redox battery with vanadium as the active material in a circulating liquid state. The electrical energy of the vanadium battery is stored in the form of chemical energy in the sulfuric acid electrolyte of vanadium ions of different valence states. The electrolyte is pressed into the battery stack by an external pump, and circulated in the closed loop of different liquid storage tanks and half-cells under the action of mechanical power. The proton exchange membrane is used as the separator of the battery stack. The electrolyte solution flows parallel to the electrode surface and an electrochemical reaction occurs. The current is collected and conducted through the double electrode plates, so that the chemical energy stored in the solution is converted into electrical energy.

[0003] The stack group is an important component of the vanadium flow battery, which includes several stacks and a rack for placing the stacks. Figure 1 The worker uses a forklift to lift the battery stack 2 and put it into the passage, then drives the forklift to turn and align the battery stack 2 with the placement rack 1, and then drives forward to place the battery stack 2 in the placement rack 1.

[0004] When using a forklift to assemble the battery stack, the battery stack is heavy and the forks of the forklift are prone to shaking, causing the battery stack to easily collide with the placement rack. In order to avoid the collision between the battery stack and the placement rack, the height and width of the placement rack are usually lengthened to increase the fault tolerance space during assembly. This causes the size of the placement rack to be much larger than the size of the battery stack, which in turn causes the size of the battery stack group to become larger, which invisibly increases the space requirements for power station operation and maintenance.

[0005] When the operator drives a forklift to place the battery stack into the placement rack, he needs to control the vehicle speed, accurately grasp the turning radius, and determine the position and timing of inserting the battery stack into the placement rack through experience. The installation process is complicated and the construction efficiency is low.

[0006] Regarding the above-mentioned related technologies, the utility model inventor believes that there are defects such as wasting power station operation and maintenance space, complicated installation process and low construction efficiency. Utility Model Content

[0007] In order to reduce the requirements for power station operation and maintenance space, simplify the installation process, and improve construction efficiency, the present application provides an installation tool for vanadium liquid flow batteries.

[0008] The present application provides an installation tool for vanadium liquid flow batteries using the following technical solution:

[0009] A mounting tool for vanadium liquid flow battery comprises a supporting mechanism and a pair of pushing mechanisms for placing a battery stack, wherein the supporting mechanism comprises a slide rail, the pushing mechanism is slidably connected to the slide rail, and the pushing mechanism also comprises an adjusting component for driving the battery stack to rise and fall.

[0010] By adopting the above technical solution, when working, a forklift is used to place the battery stack between the two pushing mechanisms, and the pushing mechanism is pushed to carry the battery stack onto the placement rack. The height of the battery stack is adjusted by adjusting the components, and the battery stack is slowly lowered onto the placement rack to avoid damage to the battery stack.

[0011] Optionally, the pushing mechanism further includes a roller, and the roller is rollingly connected to the slide rail when in operation.

[0012] By adopting the above technical solution, the pushing mechanism has less friction when moving on the slide rail, which saves effort and does not emit sharp metal friction sound, thereby improving the work efficiency of workers and the working environment of workers.

[0013] Optionally, the pushing mechanism further includes a limiting plate connected to the roller, wherein the limiting plate presses against the slide rail to prevent the pushing mechanism from being separated from the slide rail during movement.

[0014] By adopting the above technical solution, the pushing mechanism will not easily fall off the slide rail through the limiting plate, thereby improving the safety during the assembly of the battery stack and effectively avoiding potential safety hazards.

[0015] Optionally, a slide groove is provided on the slide rail for preventing the roller from falling off the slide rail, and the roller is embedded in the slide groove.

[0016] By adopting the above technical solution, the pulley is embedded in the slide groove, which can prevent the pushing mechanism from easily leaving the slide rail, thereby improving the safety during the assembly of the battery stack and effectively avoiding safety hazards.

[0017] Optionally, the pushing mechanism also includes a lower crossbeam for mounting a roller, an upper crossbeam for connecting the battery stack, and a connecting rod connecting the upper crossbeam and the lower crossbeam, wherein the connecting rod is rotatably connected to the upper crossbeam, the upper crossbeam is higher than the lower crossbeam in the horizontal direction and the lower crossbeam is away from the battery stack, one end of the adjustment component is rotatably connected to the upper crossbeam, and the end of the adjustment component away from the upper crossbeam is rotatably connected to the lower crossbeam.

[0018] By adopting the above technical solution, the battery stack is located between the two pushing mechanisms, and the adjusting component is started to make the bottom of the battery stack away from the slide rail to avoid friction between the battery stack and the slide rail during movement. After the battery stack is away from the slide rail, the battery stack is pushed into the placement rack, and the adjusting component is started again to make the battery stack contact with the slide rail, so as to separate the pushing mechanism and the battery stack, and complete the installation of the battery stack.

[0019] Optionally, the adjustment assembly includes an upper connecting member rotatably connected to the upper cross beam, a lower connecting member rotatably connected to the lower cross beam, and a first stud bolt connected between the upper connecting member and the lower connecting member.

[0020] By adopting the above technical solution, the stud bolt connection is simple, the operation is convenient, the mechanical stability is high, and the threaded connection has high adjustment accuracy and can stably place the battery stack.

[0021] Optionally, the adjustment assembly includes a cylinder, one end of the cylinder is rotatably connected to the upper beam, and one end of the cylinder away from the upper beam is rotatably connected to the lower beam.

[0022] By adopting the above technical solution, the work is lifted and lowered by the cylinder, which is highly efficient, quick and convenient.

[0023] Optionally, the supporting mechanism further includes a support foot for supporting the slide rail, and the support foot is detachably connected to the slide rail.

[0024] By adopting the above technical solution, a plurality of installation positions are usually provided on a placement rack, and the heights are different. The legs can be detachably connected to the slide rails to meet the requirements of different installation heights.

[0025] Optionally, the support leg is installed at an end of the slide rail away from the battery stack.

[0026] By adopting the above technical solution, one end of the guide rail is connected to the support frame, and the support foot is installed at the end of the slide rail away from the battery stack, so that the force on the slide rail can be more evenly distributed, effectively reducing the probability of deformation of the guide rail.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] Use a forklift to place the battery stack between two pushing mechanisms. After fixing it, push the pushing mechanism to carry the battery stack onto the placement rack. The battery stack is transported by the pushing mechanism, which ensures smooth operation and improved assembly accuracy. There is no need to heighten or widen the placement rack, which reduces the size of the battery stack group and thus reduces the space requirements for power station operation and maintenance.

[0029] The battery stack can be placed on the supporting structure using a forklift instead of being placed on the rack by a forklift, which simplifies the installation process and improves construction efficiency.

[0030] The pushing mechanism is provided with an adjustment component, which can prevent the battery stack from contacting the guide rail and the placement rack during movement, effectively protecting the integrity of the battery stack. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-9 This application is described in further detail.

[0042] The embodiment of the present application discloses an installation tool for a vanadium redox flow battery.

[0043] Reference Figure 1 , Figure 2 In order to store more electric energy, the battery stack group usually includes a plurality of battery stacks 2. A placement rack 1 for placing the battery stacks 2 is provided in the battery stack group. The placement rack 1 is divided into two layers or even more than three layers. Each layer of the placement rack 1 is a rectangular frame welded by horizontal bars 11 and vertical bars 12.

[0044] refer to Figure 2 , Figure 3The support mechanism 3 includes two slide rails 31 and two fixed plates 34, which are welded into a rectangular frame. The slide rails 31 and the fixed plates 34 are both in the shape of a cuboid. The two slide rails 31 are parallel to each other, and two reinforcing plates 36 are welded between the two slide rails 31. The reinforcing plates 36 are in the shape of a cuboid. Both ends of the reinforcing plates 36 are respectively welded between the two slide rails 31. The two reinforcing plates 36 are parallel to each other and divide the slide rails 31 into equal parts.

[0045] The support mechanism 3 further includes two mounting tubes 33, which are hollow and welded to the same fixed plate 34 and located at both ends of the fixed plate 34, and the two slide rails 31 are located between the two mounting tubes 33. The support mechanism 3 further includes two U-shaped locks 35, and four through holes are provided on the fixed plate 34 without the mounting tubes 33, and the four through holes are grouped in pairs, and the two groups of through holes are respectively provided at both ends of the fixed plate 34 without the mounting tubes 33, and the axial direction of the four through holes is parallel to the length direction of the slide rail 31.

[0046] During operation, the operator inserts two U-shaped locks 35 into two groups of through holes respectively, and the two rods of the U-shaped lock 35 are respectively located on the upper and lower sides of the cross bar 11. At this time, the two rods of the U-shaped lock 35 are screwed with bolts to complete the connection between the support mechanism 3 and the placement rack 1.

[0047] refer to Figure 3 , Figure 4 The support mechanism 3 also includes a support rod 321, which is a hollow steel pipe. The support rod 321 is provided with a hole whose axis is perpendicular to the axis direction of the support rod 321. The support mechanism 3 also includes a base 323, which is disc-shaped, and a nut is welded on the upper surface of the base 323. The support mechanism 3 also includes a second stud bolt 322 screwed on the nut. An iron plate is welded at the bottom of the support rod 321 to seal the bottom, and a nut matching the second stud bolt 322 is welded on the iron plate. The outer diameter of the support rod 321 is smaller than the inner diameter of the mounting tube 33. The support rod 321 is installed at the end of the slide rail 31 away from the placement rack 1.

[0048] During operation, the support rod 321 and the base 323 are connected by the second stud bolt 322, and then the support rod 321 is inserted into the mounting tube 33, which has a hole corresponding to the hole on the support rod 321. At this time, the bolts are inserted into the mounting tube 33 and the support rod 321 at the same time, and the two are fixed together with nuts.

[0049] refer to Figure 5 , Figure 6 , and also includes a pair of pushing mechanisms 4. When working, the battery stack 2 is placed between the two pushing mechanisms 4, and the pushing mechanisms 4 are placed on the two slide rails 31.

[0050] refer to Figure 6 , Figure 7 The pushing mechanism 4 includes an upper crossbeam 41 and a lower crossbeam 42. Both the upper crossbeam 41 and the lower crossbeam 42 are hollow tubes with square cross sections. A vertical plate 46 is welded on one surface of the upper crossbeam 41. The vertical plate 46 is also a hollow tube with a square cross section. The vertical plate 46 is perpendicular to the upper crossbeam 41. Two mounting plates 44 are welded on the surface of the upper crossbeam 41 away from the vertical plate 46. The two mounting plates 44 are mounted at both ends of the length direction of the upper crossbeam 41. The mounting plate 44 is welded by a rectangular steel plate and two triangular steel plates. The two triangular steel plates are welded on the same surface of the rectangular steel plate, and the triangular steel plate is welded to the lower bottom surface of the upper crossbeam 41.

[0051] The pushing mechanism 4 also includes two sleeves 49 welded on the lower surface of the lower beam 42. The sleeves 49 are hollow steel pipes. The axis of the sleeves 49 is parallel to the axis of the lower beam 42. The two sleeves 49 are welded at both ends of the length direction of the lower beam 42. The pushing mechanism 4 also includes a shaft sleeved on the sleeves 49, and a roller 410 welded to the shaft. The roller 410 is cylindrical, and a limit plate 411 is welded on the roller 410. The limit plate 411 is a circular steel plate, and the limit plate 411 is tightly against the side of the lower beam 42. A bolt is screwed on one end of the shaft away from the roller 410 for mounting the roller 410.

[0052] During operation, the two limit plates 411 are respectively pressed against two opposite sides of the slide rail 31 to ensure that the roller 410 rolls on the upper surface of the slide rail 31 and does not fall off the slide rail 31. In order to solve the problem that the push mechanism 4 is easy to fall off, a slide groove along the length direction of the slide rail 31 can be provided on the upper surface of the slide rail 31, and the limit plates 411 do not need to be installed. The roller 410 is embedded in the slide groove, which can also solve the problem that the push mechanism 4 is easy to fall off.

[0053] refer to Figure 7 , Figure 8 The pushing mechanism 4 also includes an adjusting component 45, which includes an upper ear plate 47 welded to the upper end of the mounting plate 44 and a lower ear plate 48 welded to the lower cross beam 42. The upper ear plate 47 and the lower ear plate 48 have the same structure and are both composed of three steel plates. Two steel plates are vertically welded to another steel plate, and a accommodating space is formed between the two parallel steel plates. The adjusting component 45 also includes an upper connecting member and a lower connecting member with the same structure. The upper connecting member includes a circular ring 453 and a thin rod 452 welded to the circular ring 453. A threaded hole is provided on the side wall of the thin rod 452 away from the end of the circular ring 453. The axis of the threaded hole coincides with the axis of the thin rod 452. A first stud bolt 451 is screwed between the two thin rods 452. The two thin rods 452 are moved closer to or away from each other by rotating the first stud bolt 451.

[0054] During assembly, bolts are inserted through the ring 453 and the upper ear plate 47 at the same time and fixed with nuts. The distance between the two steel plates of the upper ear plate 47 is greater than the thickness of the ring 453, so that the ring 453 can rotate without being locked. The lower ear plate 48 and the lower connecting piece are installed in the same way.

[0055] refer to Figure 7 The pushing mechanism 4 further includes two connecting rods 43, and the connecting rods 43 include two quarter arc plates, which are welded together by steel plates and are parallel to each other. One end of the arc plate is welded to the upper surface of the lower cross beam 42, and one end of the arc plate away from the lower cross beam 42 is rotatably connected to the upper cross beam 41.

[0056] The first stud bolt 451 in the above embodiment may be replaced with a cylinder connected between the two thin rods 452 .

[0057] refer to Fig. 9 Because a plurality of battery stacks 2 are usually required to be placed on the placement rack 1, when the upper battery stack 2 needs to be installed, the installation tube 33 is replaced with a longer one, and when the bottom battery stack 2 is placed, the installation tube 33 is replaced with a shorter one.

[0058] The implementation principle of an installation tool for vanadium redox flow batteries in the present application embodiment is as follows:

[0059] First, align the slide rail 31 with the cross bar 11 of the placement rack 1 so that the axis of the slide rail 31 coincides with the axis of the cross bar 11 , and connect the cross bar 11 and the slide rail 31 through the U-shaped lock 35 .

[0060] 2. Adjust the height of the mounting plate 44 by adjusting the assembly 45, then place the two pushing assemblies 4 opposite to each other, and the worker starts the forklift to place the battery stack 2 between the two pushing assemblies 4. The operator passes the bolts through the mounting plate 44 and screws the bolts into the threaded holes of the battery stack 2, so that the battery stack 2 is positioned between the two pushing mechanisms 4.

[0061] 3. The forklift withdraws, and the operator pushes the pushing mechanism 4, and the battery stack 2 enters onto the vertical rod 12 along the slide rail 31. When the battery stack 2 enters the appropriate position, the operator turns the first stud bolt 451, and the lower cross beams 42 of the two pushing mechanisms 4 move away from each other, and the battery stack 2 gradually approaches the placement rack 1 and falls smoothly onto the placement rack 1.

[0062] Fourth, finally remove the pushing mechanism 4 and complete the installation of the battery stack 2.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
