Description

Technical Field

[0001] This utility model belongs to the field of clamping device technology, specifically relating to a clamping device for testing flow batteries. Background Technology

[0002] A flow battery is a new type of rechargeable battery. It consists of a stack unit, electrolyte, electrolyte storage and supply unit, and management and control unit. It is a high-performance rechargeable battery that uses separate positive and negative electrolytes for each to circulate independently. During the production and use of flow batteries, they usually need to be tested, which requires the use of clamping devices to maintain the stability of the test.

[0003] According to the vanadium redox flow battery tank leak detection device with authorization announcement number CN219830238U, this patent is a known prior art. Although this patent has the advantage of being able to detect leaks in vanadium redox flow battery tanks, the technical solution of this patent still has the following defects in actual use: The rectangular push plate and clamping plate used in this patent are used to clamp the tank, which has poor clamping effect and small range, which is not conducive to ensuring the accuracy of detection. It is also inconvenient to flexibly adjust according to the diameter of the electrolyte tank, which greatly reduces the flexibility of use. At the same time, the single-station detection setting is not conducive to ensuring detection efficiency, and it does not have the function of detecting conductivity, which is not conducive to ensuring the diversity of detection and has poor practicality.

[0006] In a preferred embodiment, the damping assembly includes a damping base, and a damping shock absorber is fixedly mounted on the top of the damping base.

[0007] In a preferred embodiment, the movable component includes a support platform, which is fixedly connected to the top of the damping shock absorber.

This allows for the simultaneous testing and unloading of the electrolyte tank, ensuring testing efficiency. Furthermore, a hydraulic rod lowers the conductivity meter, allowing a metal probe to enter the electrolyte tank to test conductivity, thus enhancing testing versatility. Attached Figure Description

[0023] Please see Figure 1 This utility model provides a clamping device for testing flow batteries, including a shock-absorbing component 3, which includes a shock-absorbing base 32.

[0024] In this embodiment, the damping performance of the damping shock absorber 31 is used to buffer and eliminate the vibrations experienced by the device during use, ensuring stability during use. The brake wheel 1 and roller 2 are used to move and fix the device in place.

[0025] Please see Figure 1 and Figure 2 A movable component 4 is fixedly installed on the top of the damping component 3. The movable component 4 includes a support platform 46, which is fixedly connected to the top of the damping shock absorber 31. A first groove 45 is opened on the top of the support platform 46. A first bearing 47 is fixedly connected to the side of the inner wall of the first groove 45. A first rotating shaft 42 is rotatably connected inside the first bearing 47. A first lead screw 43 is fixedly connected to one end of the first rotating shaft 42. Two moving blocks 44 are threadedly connected to the surface of the first lead screw 43. A first motor 41 is fixedly installed on the side of the support platform 46 through a bracket. The output shaft of the first motor 41 is fixedly connected to the shaft end of the first rotating shaft 42.

[0026] In this embodiment, the first motor 41 operates, driving the first rotating shaft 42 and the first lead screw 43 to rotate, causing the two moving blocks 44 to drive the two sets of adjusting components 5 to move left and right in a cyclical manner, thereby achieving the purpose of dual-station operation, realizing the purpose of detecting and synchronously loading and unloading the electrolyte storage tank, improving detection efficiency, and ensuring practicality.

[0027] Please see Figure 1 , Figure 3 and Figure 4 Two sets of adjusting components 5 are fixedly connected to the top of the moving component 4. The adjusting components 5 include an operating table 51, which is fixedly connected to the top of the moving block 44. The operating table 51 has an inner cavity 52, and a slide rail 58 is provided at the bottom of the inner wall of the inner cavity 52. ​​A pulley 511 is slidably connected in the slide rail 58, and a gear ring 57 is fixedly connected to the top of the pulley 511. A second motor 510 is fixedly installed at the bottom of the inner wall of the inner cavity 52. ​​A drive gear 59 is fixedly connected to the output shaft of the second motor 510. The surface teeth of the drive gear 59 mesh with the teeth in the gear ring 57. The operating table 51 has three second grooves 514 inside. The inner wall surface is fixedly connected with a second bearing 53. A second rotating shaft 54 ​​is rotatably connected inside the second bearing 53. A second lead screw 55 is fixedly connected to the second rotating shaft 54. One end of the second rotating shaft 54 ​​passes through the second bearing 53 and is fixedly connected with a driven gear 512. The surface teeth of the three driven gears 512 mesh with the top teeth of the gear ring 57. A moving plate 56 is threadedly connected to the surface of the second lead screw 55. A sliding hole 513 is opened on the top of the operating table 51. The moving plate 56 is slidably connected in the sliding hole 513. Two sliding grooves 10 are opened on the top of the support table 46. A slider 11 is slidably connected in the sliding grooves 10. The slider 11 is fixedly connected to the bottom of the operating table 51.

[0028] In this embodiment, the second motor 510 operates, driving the drive gear 59 to mesh with the teeth inside the gear ring 57, causing the gear ring 57 to rotate. Then, the top teeth of the gear ring 57 mesh with the driven gear 512, driving the three second lead screws 55 to rotate. This causes the moving plate 56 to move within the sliding hole 513, driving the three clamping plates 61 to move. The clamping is flexibly adjusted according to the diameter of the electrolyte storage tank, achieving the purpose of clamping and testing electrolyte storage tanks of different specifications.

[0029] Please see Figure 1 and Figure 5The top of the two sets of adjustment components 5 is slidably connected to a clamping component 6. The clamping component 6 includes three clamping plates 61. The three clamping plates 61 are fixedly connected to the top of the three moving plates 56 respectively. Springs 64 and pressure sensors 63 are fixedly connected to the inner side of each of the three clamping plates 61. Anti-slip plates 62 are fixedly connected to the other end of the springs 64 and pressure sensors 63. The clamping plates 61 and anti-slip plates 62 are both arc-shaped.

[0030] In this embodiment, the clamping plate 61 moves to move the spring 64, pressure sensor 63, and anti-slip plate 62 to fit against the surface of the electrolyte tank, thereby clamping the electrolyte tank. The pressure sensor 63 is an AT101 model. The clamping plate 61 and anti-slip plate 62 continuously apply pressure to the surface of the electrolyte tank to observe whether leakage occurs under the set pressure. The pressure sensor 63 is connected to an existing external control panel, which displays the pressure value changes in real time, thus achieving the effect of pressure leak detection of the electrolyte tank.

[0031] Please see Figure 1 A support frame 7 is fixedly installed on the rear side of the moving component 4, a hydraulic rod 8 is fixedly installed on the top of the support frame 7, and a conductivity meter 9 is fixedly installed on the bottom of the hydraulic rod 8.

[0032] In this embodiment, the hydraulic rod 8 is operated to drive the conductivity meter 9 to move downward, so that the metal probe at the bottom of the conductivity meter 9 enters the electrolyte storage tank for detection. The conductivity meter 9 is model FK-TDS210, which realizes the effect of detecting the conductivity value. The conductivity value is displayed in real time through the external operation panel connected to the conductivity meter 9.

[0033] In the above scheme, it should be noted that: the pressure sensor 63 and the conductivity meter 9 are both existing products, and their specific structures and working principles are all existing publicly disclosed technologies. Furthermore, the electrical connection method and signal processing method between the pressure sensor 63 and the conductivity meter 9 and the operation panel are also existing publicly disclosed technologies, and will not be described in detail here.

[0034] The working principle and usage process of this utility model are as follows: First, the storage tank containing electrolyte can be placed on the operating table 51. Then, by turning on the second motor 510, the driving gear 59 is driven to mesh with the inner ring teeth of the gear ring 57 and rotate, causing the gear ring 57 to rotate. With the help of the meshing rotation of the top teeth of the gear ring 57 with the driven gear 512, the second rotating shaft 54 ​​drives the second lead screw 55 to rotate, which in turn causes the three moving plates 56 to drive the three clamping plates 61 to move towards the surface of the electrolyte storage tank until the anti-slip plate 62 is in contact with its surface. At the same time, the movement continues, squeezing the spring 64 and the pressure sensor 63. By continuously applying pressure, it is observed whether the electrolyte storage tank leaks under the set pressure.

[0035] At the same time, by opening the hydraulic rod 8, the conductivity detector 9 is moved down, so that the metal probe enters the electrolyte storage tank and comes into contact with the electrolyte to detect the conductivity.

[0036] After the test is completed, the first motor 41 is turned on, causing the first rotating shaft 42 to drive the first lead screw 43 to rotate, which in turn causes the moving block 44 to move the operating table 51, moving the tested electrolyte storage tank to one side. Another workbench loaded with an electrolyte storage tank is moved to the bottom of the conductivity detector 9 for further testing. At the same time, the second motor 510 can be controlled to work, driving the drive gear 59 to reverse, causing the gear ring 57 to drive the driven gear 512 to reverse, causing the second rotating shaft 54 ​​to drive the second lead screw 55 to reverse, causing the moving plate 56 to move and causing the clamping plate 61 and the anti-slip plate 62 to separate from the surface of the electrolyte storage tank. The staff can then remove the tested electrolyte storage tank and place a new electrolyte storage tank to be tested for subsequent testing.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
