A spring 112 is provided between the clamping plate 110 and the clamping plate 111 and the positioning plate 109. When the two positioning plates 109 are driven to move closer to each other, the positioning plate 109 drives the clamping plate 110 and the clamping plate 111 to move closer to the detection motor 105 and clamp the detection motor 105. When the detection motor 105 shakes, it drives the clamping plate 110 and the clamping plate 111 to slide on the positioning plate 109. When the shaking stops, the spring 112 drives the clamping plate 110 and the clamping plate 111 to reset, thereby resetting the detection motor 105.

When the battery 203 is placed on the base 102, the push block 210 is in contact with the battery 203, and the spring 211 is in a compressed state. The baffle 212 blocks the push block 210. When it is necessary to push out the battery 203, the drive baffle 212 moves within the base 102. 2. Release the obstruction on the push block 210. At this time, the push block 210 moves due to the deformation restoring force of the spring 211. When the push block 210 moves on the base 102, it pushes the battery 203 out of the base 102 and pushes the battery 203 into the processing box 201. A pressing plate 202 is slidably arranged on the processing box 201. A spring 204 is arranged between the pressing plate 202 and the processing box 201. A heat sink 206 is arranged on the pressing plate 202 to cool the inside of the processing box 201. A locking pin 205 is slidably arranged on the processing box 201. The locking pin 205 is intermittently inserted into the pressing plate 202. When the locking pin 205 is inserted into the pressing plate 202, it exerts pressure on the pressing plate 202. For fixation, a sealed box 208 is slidably installed at the lower end of the processing box 201. Multiple air outlets 209 are provided on the sealed box 208. Fire extinguishing racks 207 are slidably installed on both sides of the processing box 201. A fire extinguishing head 214 is slidably installed inside the fire extinguishing rack 207. The fire extinguishing head 214 extinguishes the fire on the battery 203 inside the processing box 201. When the battery 203 enters the processing box 201, the driving locking pin 205 moves out from the pressing plate 202. The pressing plate 202 moves rapidly due to the deformation restoring force of the spring 204, pressing the battery 203 into the processing box 201. Simultaneously, the heat dissipation plate 206 is activated, cooling the battery 203 inside the processing box 201. When battery 203 catches fire, the fire extinguishing frame 207 slides on the treatment box 201, sealing the treatment box 201. The fire extinguishing frame 207 drives the fire extinguishing head 214 to approach the burning battery 203, activating the fire extinguishing head 214 to extinguish the fire on battery 203. At the same time, the sealing box 208 slides inside the treatment box 201, sealing the treatment box 201 and reducing the amount of air contacted by battery 203. The air outlet 209 is connected to an external gas treatment device. The gas generated when battery 203 burns is discharged through the air outlet 209 and treated by the gas treatment device to prevent the direct emission of gas generated when battery 203 burns and causing air pollution.

[0034] The protective component 3 includes a mounting bracket 301 mounted on a sliding plate 117. A second sliding bracket 306 is slidably mounted on the mounting bracket 301. A spring 307 is provided between the second sliding bracket 306 and the mounting bracket 301. A torque detector 302 is mounted on the second sliding bracket 306. When testing the detection motor 105, the second sliding bracket 306 is driven to slide within the mounting bracket 301, and the second sliding bracket 306 drives the torque detector 302 to move synchronously. The torque detector 302 is connected to the output shaft of the detection motor 105 and detects the torque and speed parameters output by the detection motor 105. An electromagnet block is provided on the second sliding bracket 306. When the torque detector 302 reaches the working position, it drives the electromagnet block on the second sliding bracket 306 to fix the second sliding bracket 306 on the mounting bracket 301. A sliding column 303 is slidably mounted on the support plate 113. The sliding column 303 is in contact with the detection motor 105. A spring 304 is provided between the sliding column 303 and the support plate 113. A locking column 305 is slidably provided on the support plate 113, and the locking column 305 fixes the sliding column 303. In the initial state, the spring 304 is in a compressed state. When the locking column 305 is driven to move, the locking column 305 releases the fixation of the sliding column 303. The sliding column 303 moves by the deformation restoring force of the spring 304, and pushes the detection motor 105 out. The sliding column 303 pushes the detection motor 105 into the recycling box 308. The recycling box 308 is placed below the mounting frame 301. A lifting frame 309 is slidably provided in the recycling box 308. A fire extinguishing head 310 is rotatably provided on the lifting frame 309, and the fire extinguishing head 310 handles the fire on the detection motor 105.

[0035] Working principle: During operation, the detection motor 105 is placed on the sliding plate 117, driving the two sets of positioning plates 109 to move closer together. The positioning plates 109 drive the clamping plates 110 and 111 to move closer together, clamping the detection motor 105 and fixing it in place. Simultaneously, the clamping plate 114 is driven to slide on the support plate 113, fixing the detection motor 105 in place. The clamping plate 114 presses the detection motor 105 onto the sliding plate 117, thus fixing the detection motor 105 in place. The battery 20 is then placed... 3. Place the battery 203 on the base 102 and connect one end of the connecting wire 108. Drive the sliding frame 115 to slide within the sliding plate 117. The sliding frame 115 drives the connecting wire 108 to be inserted into the detection motor 105. Complete the connection between the connecting wire 108 and the detection motor 105. Drive the sliding frame 206 to slide on the mounting bracket 301. The sliding frame 206 drives the torque detector 302 to move. Connect the torque detector 302 to the output shaft of the detection motor 105. Drive the electromagnet block on the sliding frame 206 to fix the sliding frame 206. At this time, the pre-detection preparation work is completed.

[0036] The drive motor 105 rotates to perform detection on the motor 105. The input current and other parameters are changed to achieve detection of the motor 105. At the same time, the drive cam 116 rotates during detection. The cam 116 drives the shaking plate 103 to slide back and forth on the base 101. When the shaking plate 103 shakes, it drives the sliding plate 117 to slide back and forth on the shaking plate 103 due to inertia. The sliding plate 117 drives the detection motor 105 to shake, which reproduces the bumpy scene of the detection motor 105 in real operation and improves the detection accuracy of the detection motor 105. The multimeter in the connecting wire 108 monitors the current, voltage and other electrical parameters of the detection motor 105 and the battery 203 in real time.

[0037] During the testing process of the motor 105, the battery 203 is prone to overheating. The cooling head 106 is driven to dissipate heat from the battery 203. At the same time, the testing frame 107 is driven to slide on the base 102. The testing frame 107 monitors the temperature of the battery 203 in real time. When the temperature of the battery 203 is too high or there is a risk of fire, the baffle 212 is driven to slide on the base 102. The baffle 212 releases the limit on the push block 210. The push block 210 is pushed to move by the deformation restoring force of the spring 211. When the push block 210 moves on the base 102, it drives the battery 203 to move synchronously. The push block 210 quickly pushes the battery 203 into the processing box 201. At the same time, the battery 203 is disconnected from the connecting wire 108. When the battery 203 enters the processing box 201, the locking pin 205 is driven to move. The locking pin 205 releases the fixation on the pressing plate 202. The pressure plate 202 moves under the deformation restoring force of the spring 204, pressing the battery 203 into the processing box 201. The heat dissipation plate 206 is activated, which efficiently dissipates heat from the battery 203 in the processing box 201. If the battery 203 catches fire, the fire extinguishing bracket 207 is driven to slide inside the processing box 201, sealing the processing box 201. At the same time, the sealing box 208 is driven to slide inside the processing box 201, sealing the processing box 201 and reducing air circulation inside the processing box 201, thus reducing the degree of combustion of the battery 203. Simultaneously, the fire extinguishing head 214 is driven to extinguish the fire in the battery 203 inside the processing box 201. While extinguishing the fire, the combustion exhaust gas generated by the battery 203 enters the gas treatment device through the air outlet 209. After being treated by the external gas treatment device, it is discharged to avoid pollution of the air environment.

[0038] When the detection motor 105 overheats or catches fire, the operation of the electromagnet block on the sliding frame 2 306 is turned off. At this time, the sliding frame 2 306 moves due to the deformation restoring force of the spring 7 307. The sliding frame 2 306 drives the torque detector 302 to move, and the torque detector 302 is disconnected from the detection motor 105. At the same time, it drives the locking pin 2 305 to move, and the locking pin 2 305 releases the fixation on the sliding pin 303. The sliding pin 303 moves due to the deformation restoring force of the spring 6 304. The sliding pin 303 pushes the detection motor 105 to move, driving the positioning plate 109 and the clamping plate 3 114 to reset, reducing the clamping force on the detection motor 105, increasing the release speed of the detection motor 105. After the detection motor 105 enters the recovery box 308, it drives the lifting frame 2 309 and the fire extinguishing head 2 310 to move, extinguishing and cooling the detection motor 105.
