Detailed implementation manners
[0024] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.
[0025] As Figures 1-4 shown, an on-line winding temperature rise tester calibration device is proposed in an embodiment of the present invention, including:
[0026] A heating base 1;
[0027] A detection and calibration assembly; the detection and calibration assembly includes a water bath tank 2 fixedly installed on the heating base 1. An electric heating wire is installed inside the heating base 1, and the electric heating wire is located inside the water bath tank 2. The water in the water bath tank 2 can be heated by the heating wire. Among them, two second handles 7 are fixedly connected to the water bath tank 2, and second anti-slip sleeves are fixed on both of the two second handles 7. In this way, holding the second handle 7 can lift the water bath tank 2 and the heating base 1 for movement.
[0028] The upper end of the water bath tank 2 is provided with a detachable upper cover 3. The bottom of the upper cover 3 is fixedly connected with a rectangular frame 11. The rectangular frame 11 is slidably connected inside the water bath tank 2. A lock hole 13 is provided through the rectangular frame 11. A locking mechanism is further included. The locking mechanism includes a lock rod 14 that penetrates through the water bath tank 2 and is slidably connected thereto. A pulling block 10 is fixed on the lock rod 14. A spring 15 is fixed on the pulling block 10. The other end of the spring 15 is fixedly connected to the water bath tank 2. The spring 15 is sleeved outside the lock rod 14. The lock rod 14 is slidably connected in the lock hole 13. A sliding hole 16 is provided through the water bath tank 2. The lock rod 14 is slidably connected in the sliding hole 16.
[0029] When it is necessary to pour out the water in the water bath tank 2 to clean the inside of the water bath tank 2, the staff member pulls the pulling block 10 by hand. The movement of the pulling block 10 drives the movement of the lock rod 14 and makes the lock rod 14 disengage from the lock hole 13. At this time, the rectangular frame 11 is no longer limited. Since two first handles 4 are fixed to the upper end of the upper cover 3, and first anti-slip sleeves are fixed on both of the two first handles 4, another staff member holds the first handle 4 and moves it upward, and the upper cover 3 can be removed. At this time, the water bath tank 2 is no longer blocked, and the water inside can be discharged. A drain pipe can be installed on the water bath tank 2, and a valve is installed on the drain pipe. After the drainage is completed, the inner wall of the water bath tank 2 can be cleaned.
[0030] A temperature sensor 5 is installed on the upper cover 3. There is a detection probe 12 on the temperature sensor 5. The detection probe 12 is located inside the water bath tank 2. A circulating flow mechanism is installed on the water bath tank 2. The circulating flow mechanism includes a water pump 8 installed on the water bath tank 2. The water outlet end of the water pump 8 is installed with a water outlet pipe 9. The water outlet pipe 9 is connected to the water bath tank 2. The water inlet end of the water pump 8 is installed with a water inlet pipe. The water inlet pipe penetrates through the water bath tank 2 and is fixedly connected thereto. The water inlet pipe is arranged opposite to the water outlet pipe 9. When the water pump 8 works, the water in the water bath tank 2 can be transported into the water bath tank 2 through the water inlet pipe and the water outlet pipe 9, so as to realize the flow of the hot water in the water bath tank 2, make the water temperature more uniform, and avoid inaccurate detection caused by temperature difference in water temperature detection; the flowing hot water can be measured for temperature through the detection probe 12, and the water temperature can be known through the temperature sensor 5 in cooperation with external devices (such as a computer).
[0031] An installation hole 6 is penetrated through the upper cover 3. The on-line winding temperature rise tester can extend into the water bath tank 2 through the installation hole 6. The detection end of the on-line winding temperature rise tester is extended into the water bath tank 2 through the installation hole 6, and the temperature detected by the on-line winding temperature rise tester is compared with the temperature detected by the temperature sensor 5. If there is a situation where the temperatures are different, the on-line winding temperature rise tester can be calibrated;
[0032] The power of the heating base 1 can be increased, so that the water temperature can be increased, enabling the on-line winding temperature rise tester to detect different water temperatures. In cooperation with the detection of the water temperature by the temperature sensor 5, the calibration of the on-line winding temperature rise tester is more accurate and more convenient to use, avoiding the drawbacks of detection errors in the prior art.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
