Description

Technical Field

[0001] The utility model relates to the technical field of liquid leakage detection devices, in particular to a battery liquid leakage detection device. Background Technique

[0002] In the prior art, in order to ensure the safe use of a battery pack, it is often necessary to perform real-time detection and monitoring on the battery pack, and among them, battery liquid leakage detection is an important link to ensure the safe use of the battery.

[0003] In the prior art for the detection of battery soft packs, during daily use, it is checked by manual visual inspection whether there are foreign objects, liquids, etc. on the surface of the battery shell. This method is simple and direct, but it depends on the observation ability and experience of the detector, and if the battery soft pack only leaks slightly, relying solely on observation is relatively slow. In the prior art, there is also a method of adjusting the air pressure and using positive pressure or negative pressure to judge whether the battery soft pack leaks, but the entire device needs to be sealed inside and the device needs to be maintained at a specific air pressure, which is more troublesome to use. Therefore, an improved battery liquid leakage detection device is needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a battery liquid leakage detection device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A battery liquid leakage detection device, including a fixed frame, a detection mechanism for detecting the sealing performance of the battery is arranged at the upper end of the fixed frame. The detection mechanism includes a rotating disk, a clamping frame, a sliding groove, a first clamping block, a second clamping block, and a driving screw. The rotating disk is movably arranged at the middle part of the upper end of the fixed frame through a rotating shaft. A plurality of clamping frames are evenly and fixedly arranged on the outer surface of the upper end of the rotating disk. A sliding groove is opened on the outer surface of the clamping frame. The first clamping block is movably clamped inside the sliding groove through a sliding block. The second clamping block is fixedly arranged at the lower end of the clamping frame. The driving screw is rotatably screwed on the upper end of the clamping frame through a thread. A driving mechanism for driving the rotation of the rotating disk is arranged between the fixed frame and the rotating disk.

[0006] Preferably, the driving mechanism includes a motor, a speed reducer, a first pulley, a second pulley, and a transmission belt. One side of the upper end of the fixed frame is fixedly provided with a motor. A speed reducer is arranged on one side of the motor. The power output shaft end of the motor is in transmission connection with the power input shaft end of the speed reducer. The power output shaft end of the speed reducer is fixedly provided with a first pulley. The outer surface of the rotating shaft where the rotating disk is located is fixedly provided with a second pulley. The outer surfaces of the first pulley and the second pulley are sleeved with a transmission belt. The driving mechanism can conveniently drive the rotating disk to rotate quickly, and then the leakage of the battery pack can be quickly detected by using centrifugal force. Moreover, the whole detection process does not need to maintain air pressure and seal, and it is more convenient to use.

[0007] Preferably, a screwing block is fixedly provided at the upper end of the driving screw. The driving screw can be conveniently rotated through the screwing block.

[0008] Preferably, a fixing ring is fixedly provided on the outer side of the upper surface of the rotating disk. The fixing ring can play a role in convenient observation. When the battery pack to be detected leaks liquid, the leaked electrolyte will be thrown out and the electrolyte will splash onto the upper end of the inner side wall of the fixing ring. At this time, it is only necessary to penetrate the inner side wall of the fixing ring to judge whether the battery pack leaks liquid.

[0009] Preferably, the lower end of the driving screw is movably connected with the first clamping block through an annular clamping groove, so that the driving screw can rotate relative to the first clamping block, but cannot have relative displacement; by rotating the driving screw, the first clamping block can be driven to move up and down under the action of the screw.

[0010] Preferably, a plurality of support members are uniformly and fixedly provided on the outer surface around the upper end of the fixed frame. The upper ends of the support members are movably provided with support rollers through rotating shafts. The support rollers are mutually attached to the outer surface of the lower end of the rotating disk. The overall running stability of the rotating disk can be improved through the support rollers.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the driving screw is rotated through the screwing block, so that the driving screw pushes the first clamping block to move downward, thereby the first clamping block and the second clamping block can clamp the corner of the battery pack, so that the battery pack can be firmly fixed between the first clamping block and the second clamping block. Subsequently, the rotating disk and the battery pack on the rotating disk can be driven to rotate through the motor, the speed reducer, the first pulley, the second pulley, and the transmission belt. In this way, the battery leakage is quickly detected by using centrifugal force.

[0013] 2. The whole detection process of the present utility model does not need to maintain air pressure and seal, and it is more convenient to use. Description of the Drawings

A driving mechanism for driving the rotating disk 2 to rotate is arranged between the fixed frame 1 and the rotating disk 2.

[0021] The driving mechanism includes a motor 8, a speed reducer 9, a first pulley 10, a second pulley 11, and a transmission belt 12. One side of the upper end of the fixed frame 1 is fixedly provided with a motor 8. A speed reducer 9 is arranged on one side of the motor 8. The power output shaft end of the motor 8 is in transmission connection with the power input shaft end of the speed reducer 9.

The outer surface of the rotating shaft where the rotating disk 2 is located is fixedly provided with a second pulley 11. The outer surface of the first pulley 10 and the second pulley 11 is sleeved with a transmission belt 12. The rotating disk 2 can be conveniently driven to rotate quickly through the driving mechanism, and then the leakage detection of the battery pack can be quickly carried out by using centrifugal force. Moreover, the whole detection process does not need to maintain air pressure and sealing, which is relatively convenient to use;

[0022] A screwing block 13 is fixedly arranged at the upper end of the driving screw 7. The driving screw 7 can be conveniently rotated through the screwing block 13;

[0023] A fixing ring 14 is fixedly arranged on the outer side surface of the upper end of the rotating disk 2. The fixing ring 14 can play a role in convenient observation. When the battery pack to be detected leaks, the leaked electrolyte will be thrown out and the electrolyte will splash onto the upper end of the inner side wall of the fixing ring 14. At this time, it is only necessary to penetrate the inner side wall of the fixing ring 14 to judge whether the battery pack leaks;

[0024] The lower end of the driving screw 7 is movably connected with the first clamping block 5 through an annular clamping groove, so that the driving screw 7 can rotate relative to the first clamping block 5, but cannot have relative displacement; by rotating the driving screw 7, the first clamping block 5 can be driven to move up and down under the action of the screw;

[0026] Working principle: When using this device, the battery pack to be monitored can be placed between the first clamping block 5 and the second clamping block 6. Then, the driving screw 7 is rotated through the screwing block 13, so that the driving screw 7 pushes the first clamping block 5 to move downward, and thus the corners of the battery pack can be clamped by the first clamping block 5 and the second clamping block 6, so that the battery pack can be firmly fixed between the first clamping block 5 and the second clamping block 6. Then, the rotating disk 2 and the battery pack on the rotating disk 2 can be driven to rotate through the motor 8, the speed reducer 9, the first pulley 10, the second pulley 11, and the transmission belt 12. In this way, the battery leakage detection can be quickly carried out by using centrifugal force. Moreover, the whole detection process does not need to maintain air pressure and sealing, which is relatively convenient to use;

[0027] In order to ensure the detection stability of the battery pack, after a detection is completed, the battery pack can be inverted so that the first clamping block 5 and the second clamping block 6 clamp the other corner of the battery pack, and then detect again. If no electrolyte spills out, it can indicate that the overall structure of the battery pack has good sealing performance.
