Description

Technical Field

[0001] The utility model relates to the technical field of insulating oil, in particular to an automatic sampling, oil draining and cleaning device for insulating oil testing. Background Art

[0002] Insulating oil is a mineral oil with good electrical insulation properties. In the process of producing insulating oil, it is often necessary to conduct various tests on the insulating oil to evaluate the quality of the insulating oil and ensure the safe operation of the power equipment. However, in the process of testing each portion of insulating oil, the oil cup needs to be removed after each experiment, the waste liquid in the oil cup needs to be poured out, and then it needs to be manually rinsed. After rinsing, it needs to be manually wiped dry before the next experiment can be carried out. However, the rinsing steps of the oil cup are more troublesome, which makes the overall test efficiency low. At the same time, after the oil cup is cleaned, the user often pours the new insulating oil from the outside. However, when pouring the insulating oil, the oil cup cannot be sealed and protected, resulting in the possibility that dust and impurities from the outside may fall into the oil cup and mix with the insulating oil, thereby affecting the subsequent tests and data collection. Therefore, we propose an automatic sampling, oil discharge and cleaning device for insulating oil testing to solve the above problems. Utility Model Content

[0027] The working principle of the automatic sampling, oil draining and cleaning device for insulating oil testing:

[0028] During use, first, when it is necessary to test the raw materials, the No. 1 cylinder 401 will drive the connecting block 403 and the oil inlet pipe 402 to move downward, so that the oil inlet pipe 402 enters the interior of the oil cup 5, and then the external oil pump can inject the raw materials into the oil inlet pipe 402 into the interior of the oil cup 5 to realize automatic sampling. After the raw material sampling is completed, the No. 1 cylinder 401 will drive the oil inlet pipe 402 and the connecting block 403 to reset, and then the test bench 3 can cooperate with the oil cup 5 to test the raw materials. After the raw materials are used, the electric slide rail 405 cooperates with the slider 406 to the No. 2 cylinder The height of the mechanical gripper 407 and the mechanical gripper 408 is adjusted, and then after the adjustment is completed, the second cylinder 407 pushes the mechanical gripper 408 to clamp the oil cup 5, and then after the oil cup 5 is clamped, the second cylinder 407 pulls the mechanical gripper 408 and the oil cup 5 to move to the upper end of the interior of the isolation frame 404, and then the mechanical gripper 408 controls the oil cup 5 to rotate, so as to realize automatic dumping and draining of the waste oil in the oil cup 5, so that the waste oil falls into the interior of the isolation frame 404, and then the valve at the upper end of one of the recovery pipes 409 is opened, so that the waste oil flows along the recovery pipe 409 into the waste oil recovery pipe 409 of the outside. The waste oil is collected uniformly in the collection box. After the waste oil is dumped and collected, the recovery pipe 409 and its valve for recovering the waste oil are closed, and the recovery pipe 409 and valve for recovering the waste liquid are opened. Then the third cylinder 410 will push the connecting pipe 411 to move, so that the connecting pipe 411 drives the extension pipe 413 and the cleaning rack 417 to enter the interior of the oil cup 5. Then the cleaning liquid can enter the interior of the extension pipe 413 along the guide pipe 412 and the connecting pipe 411, so that the cleaning liquid flushes the interior of the oil cup 5 along the through hole 414. At the same time, the motor 418 will drive the second Gear 419 rotates, so that gear No. 419 controls gear No. 1 416 to drive extension tube 413 and cleaning rack 417 to rotate by meshing with gear No. 1 416, so that cleaning rack 417 and extension tube 413 perform all-round cleaning of the inside of oil cup 5. At the same time, the cleaning liquid will be discharged and recovered along the recovery pipe 409 with the valve opened. After the cleaning of oil cup 5 is completed, mechanical gripper 408 can cooperate with slider 406 and cylinder No. 2 407 to put oil cup 5 on the upper end of test bench 3 again, and then repeat the above steps to test a new batch of raw materials.

[0029] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
