Description

Technical Field

[0001] The utility model relates to the technical field of moisture measuring instruments, in particular to an automatic sampling moisture measuring instrument. Background Art

[0002] An instrument that can detect the moisture content in a sample is called a moisture meter. Moisture meter can be widely used in all industries that require rapid determination of moisture, such as medicine, grain, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemicals, tea, food, meat, textiles, agriculture, forestry, papermaking, rubber, plastics, textiles, etc.

[0003] The authorization announcement number is CN217180911U. An automatic sampling moisture meter includes a moisture meter, a sampling tube is fixedly arranged at the lower end of the moisture meter, and a display screen is installed on the upper left side of the moisture meter, and a sample storage cavity is opened on the moisture meter on the right side of the display screen, and the sample storage cavity is connected with the sampling tube. When sampling, the limit adjustment column is first adjusted to a fixed height according to the scale frame, and then the sampling tube is placed in the insulating oil, and then the locking block is pulled out of the locking hole. In this way, under the action of the upper spring, the piston moves upward to suck the sample into the sample storage cavity, and when the L-shaped iron frame contacts the limit strip, it is adsorbed by the magnet, so that the piston can be fixed, ensuring that the piston rises to the same height each time sampling is performed, and the piston will not rebound, thereby ensuring that the sampling amount is the same each time;

[0004] The above document can ensure that the sampling volume is the same each time, but in actual use, due to the different water content of the insulating oil, after the insulating oil is tested, a certain amount of insulating oil will be attached to the detection end of the test pen. In the subsequent test process, the insulating oil attached to the surface of the detection end will be mixed with the insulating oil tested this time, and the user needs to manually clean it. Since the user manually cleans it, there may be incomplete cleaning, there will be certain detection errors, resulting in inaccurate test results, and there will still be a certain amount of residue. Therefore, we provide an automatic sampling moisture meter. Utility Model Content

[0032] Specifically, when it is necessary to measure the moisture content of the insulating oil, the user starts the water pump 3 to work, and the external insulating oil is transported to the inner cavity of the water storage tank 8 through the cooperation of the first pipe 2 and the second pipe 4 through the water pump 3. The first pipe 2 and the second pipe 4 cooperate to realize the function of automatic sampling. After the sampling is completed, the user starts the measuring instrument 5 to work. After the start-up is completed, the user picks up the detection pen 1 and places the detection end of the detection pen 1 in the inner cavity of the water storage tank 8 to detect the moisture content in the insulating oil. After the detection is completed, the detection pen 1 is placed in the inner cavity of the water storage tank 8 to detect the moisture content in the insulating oil. When cleaning the pen 1, the user injects cleaning liquid into the inner cavity of the cleaning box 22.

After the placement is completed, the user starts the ultrasonic generator 12 to work, and the ultrasonic generator 12 drives the pulse line 13 to work. The pulse line 13 generates ultrasonic oscillations to clean the insulating oil attached to the detection end of the detection pen 1, so that the insulating oil attached to the detection end of the detection pen 1 falls off. In the subsequent detection process, there will be no errors in the detection results, and the detection results are more accurate.

[0033] A hot air blower 21 is fixedly installed at the front end on the left side of the top of the base plate 7, and the output end of the hot air blower 21 is fixedly connected to an air outlet pipe 20, and the output end of the air outlet pipe 20 is provided with a plurality of air outlet heads 19.

After the sampling is completed, the user starts the measuring instrument 5 to work. After the start-up is completed, the user picks up the detection pen 1 and places the detection end of the detection pen 1 in the inner cavity of the water storage tank 8 to detect the moisture contained in the insulating oil. After the detection is completed, the user places the detection pen 1 in the inner cavity of the support frame 16. After the placement is completed, when it is necessary to clean the detection pen 1, the user injects cleaning liquid into the inner cavity of the cleaning box 22.

After cleaning, the user starts the electric telescopic rod 11 to move upward, so that the support frame 16 drives the detection pen 1 to move upward, so that the detection end of the detection pen 1 is level with the position of the air outlet 19. At this time, the user starts the hot air blower 21 to work, and the hot air blower 21 outputs hot air under the cooperation of the air outlet pipe 20 and the air outlet 19, so that the hot air contacts the detection end of the detection pen 1 to achieve rapid drying.
