Description

Technical Field

[0001] This invention belongs to the technical field of cable-related equipment, and in particular relates to a fixing device for vanadium redox flow battery cables. Background Technology

[0002] Vanadium redox flow batteries, as a highly efficient, safe, and long-life electrochemical energy storage technology, have become one of the core energy storage devices in fields such as new energy power generation and consumption, grid peak shaving and frequency regulation, distributed energy storage, and backup power supply, thanks to their advantages such as recyclable electrolyte, flexible charge and discharge depth, and strong environmental adaptability. With the accelerated global energy transition to clean energy, the installed capacity of vanadium redox flow batteries continues to grow, with single-unit power increasing from tens of kilowatts to megawatts and even tens of megawatts. Correspondingly, the system structure is also evolving from compact single units to modular clusters. In a vanadium redox flow battery system, cables serve as the core carrier for power transmission, undertaking the power connection functions between the battery stack and the energy storage converter, between individual cells and the busbar within the battery stack, and between the system's auxiliary equipment. The stability of these connections directly determines the system's power supply reliability, power transmission efficiency, and operational safety.

[0003] When laying cables for electrical components of some equipment manufacturers, a device is installed along the cable laying route to fix the cable. The two ends of the cable are connected to two electrical components, and the middle of the cable is laid on the device to prevent the cable from being suspended in the air. In order to prevent the cable laid on the device from falling off the device, the cable needs to be fixed to the device.

[0004] Currently, stainless steel cable ties are commonly used to secure cables to the device. However, when using stainless steel cable ties to bind cables, special tools are usually required to insert one end of the cable tie into the buckle on the other end and tighten it. This process is cumbersome. Furthermore, when it is necessary to replace the cable, the existing cable ties must be removed before new ones can be used, resulting in a large workload and low efficiency.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1 A vanadium redox flow battery cable fixing device includes a base plate 1, vertical rods 2, mounting plates 3, clamping mechanisms 4, and a driving mechanism 5. The base plate 1 is placed horizontally, and through holes 11 are formed at its four corners. Pins or similar devices can be inserted into these through holes 11 to fix the base plate to the ground. There are two vertical rods 2, arranged along their height and spaced apart at both ends of the top surface of the base plate 1 along its length. Reflective warning strips 21 are affixed to each of the two vertical rods 2, also arranged along their height. There are multiple mounting plates 3 (three in this embodiment), positioned between the two vertical rods 2 and evenly spaced along their height. Each mounting plate 3 is arranged along the length of the base plate 1, with both ends fixed to the two vertical rods 2. Multiple sets of clamping mechanisms 4 are used, each corresponding to one of the mounting plates 3. Each pair of clamping mechanisms 4 is mounted on a corresponding mounting plate 3 for clamping the cable. The drive mechanism 5 is used to provide power to the clamping mechanism 4.

[0024] When in use, the operator first fixes the base plate 1, then places the cable at the clamping mechanism 4, and starts the drive mechanism 5 to clamp and fix the cable. When the cable needs to be replaced, the drive mechanism 5 is started again so that the clamping mechanism 4 no longer clamps the cable, and the cable can be replaced. The operation is convenient and can improve work efficiency.

[0025] Reference Figure 1-3 A slide rail 31 is fixedly provided on the side of the mounting plate 3 along its width direction, and the slide rail 31 is arranged along the length direction of the mounting plate 3. A slide plate 32 is slidably connected to the slide rail 31. The length of the slide plate 32 is smaller than the length of the mounting plate 3, and the slide plate 32 is also arranged along the length direction of the mounting plate 3. Two sets of clamping mechanisms 4 are respectively arranged on the slide plate 32 and spaced apart along the length direction of the slide plate 32. Each set of clamping mechanisms 4 includes a first clamping assembly 41 and a second clamping assembly 42. The first clamping assembly 41 includes a first clamping plate 411, a second clamping plate 412, and a fixing rod 413. The first clamping plate 411 is arranged along the height direction of the mounting plate 3, and a first rotating rod 414 is fixedly provided at the bottom end of the first clamping plate 411. The first rotating rod 414 is arranged along the width direction of the mounting plate 3, and the end of the first rotating rod 414 away from the first clamping plate 411 is rotatably connected to the side of the mounting plate 3 above the slide plate 32. A first half-gear 415 is fixedly mounted on one end of the first rotating rod 414 near the first clamping plate 411, and the first half-gear 415 is disposed between the mounting plate 3 and the first clamping plate 411. A second clamping plate 412 is also disposed along the height direction of the mounting plate 3, and is located at the same height on one side of the first clamping plate 411. A second rotating rod 416 is fixedly mounted on the bottom end of the second clamping plate 412, and the second rotating rod 416 is parallel to the first rotating rod 414, with one end of the second rotating rod 416 rotatably connected to the side of the mounting plate 3 above the sliding plate 32. A second half-gear 417 is fixedly mounted on one end of the second rotating rod 416 near the second clamping plate 412, and the second half-gear 417 is disposed between the mounting plate 3 and the second clamping plate 412, with the first half-gear 415 and the second half-gear 417 meshing. The lengths of both the first rotating rod 414 and the second rotating rod 416 are longer than the width of the slide plate 32, so that the first clamping plate 411 and the second clamping plate 412 are located on the side of the slide plate 32 away from the mounting plate 3. A U-shaped plate 418 is fixedly provided at the bottom end of the second clamping plate 412. The U-shaped plate 418 has a U-shaped groove 4181 and is located on the side of the slide plate 32 away from the mounting plate 3. A fixing rod 413 is arranged parallel to the first rotating rod 414 and is fixed on the side of the slide plate 32 within the U-shaped groove 4181 of the U-shaped plate 418. It moves within the U-shaped groove 4181 of the U-shaped plate 418 but will not disengage from the U-shaped groove 4181. The drive mechanism 5 drives the slide plate 32 to move.

[0026] In use, the drive mechanism 5 is activated, which moves the slide plate 32. The movement of the slide plate 32 causes the fixed rod 413 to move left and right. Since the fixed rod 413 moves within the U-shaped groove 4181 of the U-shaped plate 418, and the U-shaped plate 418 is fixedly connected to the second clamping plate 412, it can drive the second clamping plate 412 to rotate around the second rotating rod 416 as an axis. This causes the second rotating rod 416 and the second half gear 417 to rotate. Since the first half gear 415 and the second half gear 417 mesh, the first half gear 415 also rotates. The first half gear 415 and the second half gear 417 move relative to each other, thereby driving the first clamping plate 411 to rotate around the first rotating rod 414 as the axis, shortening the distance between the top ends of the first clamping plate 411 and the second clamping plate 412, thus clamping the cable and fixing it better. When the cable needs to be replaced, the drive mechanism 5 is activated again, causing the slide plate 32 to move in the opposite direction, which can lengthen the distance between the top ends of the first clamping plate 411 and the second clamping plate 412, eliminating the clamping force on the cable, allowing the cable to be removed for replacement. The operation is simple and helps to improve work efficiency.

[0027] Reference Figure 1-3 The second clamping components 42 are respectively disposed at the first clamping plate 411 and the second clamping plate 412. Taking the second clamping component 42 at the first clamping plate 411 as an example, the second clamping component 42 includes a third clamping plate 421, a telescopic rod 422, and a spring 423. The side of the third clamping plate 421 away from the first clamping plate 411 is an arc surface, and the third clamping plate 421 is fixed to the side of the first clamping plate 411 near the second clamping plate 412. The side of the first clamping plate 411 near the second clamping plate 412 is recessed inward, forming a groove with the third clamping plate 421. There are multiple telescopic rods 422, and in this embodiment there are three. The three telescopic rods 422 are evenly spaced in the groove. The telescopic rods 422 are disposed perpendicular to the side of the third clamping plate 421 near the groove, and one end of the telescopic rod 422 is fixed to the first clamping plate 411 and the other end is fixed to the third clamping plate 421. There are also multiple springs 423, each corresponding to one of the multiple telescopic rods 422. In this embodiment, there are three springs 423. The springs 423 are wound around the corresponding telescopic rods 422, and their two ends are fixed to the first clamping plate 411 and the third clamping plate 421, respectively. The second clamping assembly 42 at the second clamping plate 412 has the same structure as described above, that is, the first clamping plate 411 is replaced by the second clamping plate 412.

[0028] When the cable is placed between the two third clamping plates 421, and the first clamping plate 411 and the second clamping plate 412 clamp the cable, the slide plate 32 continues to move. The cable will squeeze the telescopic rod 422 and the spring 423. The spring 423 will be compressed, and then the spring 423 will generate elastic force on the third clamping plate 421, which will also generate elastic force on the cable. This will increase the clamping force on the cable, strengthen the fixation of the cable, and reduce the cable falling off.

[0029] Reference Figure 1 The drive mechanism 5 includes a first drive component 51 and a second drive component 52. The number of first drive components 51 is multiple; in this embodiment, there are three sets, each corresponding to one of the three slide plates 32. Each set of first drive components 51 is respectively disposed at one end of the three slide plates 32 along their length. (Refer to...) Figure 2 Each first drive assembly 51 includes a rack 511 and a gear 512. The rack 511 is arranged along the length of the mounting plate 3, and one end of the rack 511 is fixed to one end of the slide plate 32 along its length. A third rotating rod 513 is rotatably connected to the side of the mounting plate 3 above the rack 511. The third rotating rod 513 is arranged parallel to the first rotating rod 414 and passes through the mounting plate 3. The gear 512 is fixed to the end of the third rotating rod 513 near the rack 511 and meshes with the rack 511. The second drive assembly 52 drives the third rotating rod 513 to rotate.

[0030] Reference Figure 1 and Figure 4 The second drive assembly 52 includes a motor 521, which is fixed to the side of the vertical rod 2 near the rack 511, and the output shaft of the motor 521 is arranged parallel to the first rotating rod 414. A first pulley 522 is fixed to the output shaft of the motor 521, and a second pulley 523 is fixed to the third rotating rod 513 near the motor 521, with a first belt 524 wound between the first pulley 522 and the second pulley 523. A third pulley 525 is also fixed to the third rotating rod 513 near the motor 521, and a fourth pulley 526 is fixed to the third rotating rod 513 at the middle position, with a second belt 527 wound between the third pulley 525 and the fourth pulley 526. A fifth pulley 528 is also fixed to the third rotating rod 513 at the middle position, and a sixth pulley 529 is fixed to the remaining third rotating rod 513, with a third belt 5291 wound between the fifth pulley 528 and the sixth pulley 529.

[0031] When motor 521 is started, its output shaft drives the first pulley 522 to rotate. Since the first pulley 522 and the second pulley 523 are connected by the first belt 524, the second pulley 523 rotates, causing the third rotating rod 513, which is fixed to the second pulley 523, to rotate. This, in turn, drives the corresponding gear 512 to rotate, causing the rack 511 meshing with it to move left and right, ultimately enabling the slide plate 32 to move left and right, providing power to the clamping mechanism 4. Similarly, the second belt 527 enables the rotation of the third rotating rod 513 in the middle position, thereby enabling the rotation of its corresponding gear 512. The third belt 5291 enables the rotation of the remaining third rotating rod 513, also enabling the rotation of its corresponding gear 512. Ultimately, by controlling the movement of the slide plate 32 simultaneously through a single motor 521, the clamping mechanism 4 can be synchronously controlled to clamp the cable, facilitating cable replacement.

[0032] The working principle of this invention is as follows: When in use, the operator first fixes the base plate 1 to the ground, places multiple cables at the clamping mechanism 4, and starts the motor 521, which enables the clamping mechanism 4 to clamp the cables and fix them. When it is necessary to replace the cables, the operator starts the motor 521 again, which enables the clamping mechanism 4 to release the cables, making it convenient for the operator to replace them. The operation is convenient and can improve work efficiency.

[0033] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
