One end of the device 5 close to the side wall of the cabinet 1 is fixedly connected with two telescopic rods 50, and the left and right ends of the cabinet 1 are fixedly connected with two vertical poles 12. The telescopic rod 50 is sleeved inside the vertical pole 12 and the telescopic rod 50 is limited inside the vertical pole 12 to dissipate heat inside the cabinet 1 as a whole and avoid that the overall temperature inside the cabinet 1 is too high, and it is difficult to distinguish whether the detection data is the temperature data inside the cabinet 1 or the abnormal temperature rise of the detection port 20 caused by the abnormality of the contact or the output interface of the circuit breaker 2. At the same time, after the detection, the heat dissipation device 5 cooperates with the adjustment device 3 to dissipate heat from the detection port 20 after the temperature measurement to avoid the circuit breaker 2 from malfunctioning due to excessive temperature due to untimely processing by the user.

[0052] Working principle: In the initial state, the two heat sinks 52 are in a vertical state. The control center 30 is used to turn on the air coolers at the two air cooling plates 53 to dissipate heat and cool down the circuit breaker 2 from both sides of the circuit breaker 2 to prevent the internal ambient temperature of the cabinet 1 from being too high and affecting the normal operation of the circuit breaker 2. When it is necessary to detect the temperature inside the cabinet 1 to find out whether the temperature rise at the contacts and outlet connectors of the circuit breaker 2 is abnormal, the two air cooling plates 53 are closed and continue to blow air. The control center 30 is used to control the first rotating drive component 31 to turn on. The first rotating drive component 31 is turned on to drive the first rotating disk 32 and the first rotating column 320 to rotate. The first rotating column 320 rotates one circle to drive the return groove plate 33 to make a linear reciprocating motion from right to left or from left to right. The first rotating column 320 only rotates to the left or right by a quarter of a circle. At this time, the return groove plate 33, the adjustment plate 34 and the connecting rod 35 are all at the leftmost or rightmost position they can move. The adjustment plate 34 moves to the left or right to drive the temperature measuring device 4 to move to the detection port 20 on the left or the detection port 20 on the right. At this time, the control center 30 controls the cleaning device 43 to start cleaning the first detection port 20 that the cleaning device 43 can contact. During this process, the collection port 461 does not contact the detection port 20. After the cleaning device 43 finishes cleaning, the second rotating drive component 41 is turned on and drives the first gear 42 and the first screw 421 to rotate. At this time, the cleaning device 43 is affected by the rotation of the first screw 421. The influence moves down to the next detection port 20, and the first gear 42 rotates to drive the second gear 44 and the second screw 45 to rotate. The second screw 45 rotates to move the collection port 461 down to the cleaned detection port 20 for temperature detection. The detected temperature data is uploaded to the control center 30 by the thermometer 46 for recording, and then the above steps are repeated. The cleaning device 43 cleans the next detection port 20 and moves to the third detection port 20, and the collection port 461 moves down to the next detection port 20 for temperature detection. The length of the first screw 421 is greater than the length of the second screw 45. Therefore, when the collection port 461 is at the last detection port 20 in the longitudinal direction, the cleaning device 43 does not contact the detection port 20. At the detection port on the left or right side, After all the detections of 20 are completed, the device is reset by reversing the second rotary drive component 41. At this time, the difference from the above steps is that the collection port 461 first collects the temperature data of the detection port 20 and the surrounding area again, and then the second rotary drive is turned on to drive the cleaning device 43 to move up to clean the detection port 20 for the second time until the device is reset. After the detection of the detection port 20 on the left or right side is completed, the first rotary drive component 31 drives the first rotating disk 32 and the first rotating column 320 to rotate from the current position by half the length of the circumference. At this time, the temperature measuring device 4 is at the remaining row of detection ports 20 that have not been detected. Subsequently, the temperature of the remaining detection ports 20 is detected in the same way as above. At this time, the device collects data twice at all detection ports 20 and the surrounding areas.The user can then compare the two data to determine whether the test data is accurate. The device can set up multiple vertical rows of test points for temperature detection according to the movement of the adjustment device 3 and the actual contacts and outlet connector positions of the circuit breaker 2, so that the device can perform two temperature tests on different positions of the circuit breaker 2 in one operation, thereby improving the accuracy of the device's test data.

[0053] When the cleaning device 43 moves to the detection port 20, the control center 30 controls the third rotation drive assembly 431 to start, and the third rotation drive assembly 431 starts to drive the second rotating disk 432 and the second rotating column 433 to rotate. When the second rotating disk 432 and the second rotating column 433 rotate, the swing arm 434 is driven to move through the swing slot 4340. Under the restriction of the shaft 4342, the swing arm 434 can only make a reciprocating swing motion from right to left or from left to right. The swing arm 434 moves in an arc shape. The toothed disc 4341 performs reciprocating swinging motion, and the swinging of the toothed disc 4341 drives the toothed plate 435 and the cleaning plate 4350 to move. Due to the limitation of the slide bar 4351 and the slide slot 436, the cleaning plate 4350 can only perform a linear reciprocating motion from left to right or from right to left. The cleaning plate 4350 performs a linear reciprocating motion at the detection port 20 to reciprocate and wipe away dust and debris at the detection port 20, thereby preventing the dust or debris from affecting the results of subsequent temperature detection, improving the accuracy of the temperature detection of the device, and facilitating user use;

[0054] When the first rotation drive assembly 31 is turned on to adjust the temperature measuring device 4 to the detection port 20 on the left or right side, the connecting rod 35 away from the detection port 20 drives the heat sink 52 connected to the inside of the heat sink 5 to deflect by moving in the adjustment slot 520, while the heat sink 52 close to the detection port 20 cannot deflect due to the obstruction of the baffle 51. At this time, the heat sink 5 and the telescopic rod 50 close to the detection port 20 are driven by the connecting rod 35 through the adjustment slot 520 to move, and the telescopic rod 50 is moved and stored in the vertical rod 12, and the heat sink 5 close to the detection port 20 remains vertical. In this process, the air cooler is not turned on because the other row of detection ports 20 has not been detected. After all the detection of the detection ports 20 in this row is completed, the first rotation drive assembly 31 drives the temperature measuring device 4 to move to When the other row of detection ports 20 is detected, the two heat dissipation devices 5 move in the same way as described above. At this time, the deflected heat dissipation device 5 turns on the air cooler to dissipate heat for the detected detection ports 20 and surrounding areas, so as to avoid local overheating and abnormal temperature rise, which may cause the user to fail to deal with it in time and lead to circuit breaker 2 failure. At the same time, it can also avoid that the temperature difference between the detection port 20 and the surrounding area is small during the next detection, which makes it difficult for the user to judge based on the data whether the abnormality of the circuit breaker 2 contact or the output interface causes the abnormal temperature rise of the detection port 20 or the excessive temperature inside the cabinet 1 causes the temperature of the detection port 20 to be too high. At this time, the vertical heat dissipation device 5 does not turn on the air cooler, so as to avoid the air cooler turning on to dissipate heat for the detection port 20 being detected, resulting in inaccurate temperature data. This improves the accuracy of the temperature detection of the device and the protection effect on the circuit breaker 2, which is convenient for users to use.
