[0031] The working principle of the utility model is as follows: first, the worker moves the device to the vicinity of the condenser hot well, and uses the brake pad 19 to lock the universal wheel 18, then the worker uses the pipeline to connect the delivery pipe 17 with the condenser hot well, and then uses the power provided by the vacuum pump body 2 to extract the condensate inside the condenser hot well into the interior of the sampling pump frame, so that the condensate is filtered by the filter frame 4 and then discharged from the vacuum pump body 2, and then the worker performs chemical analysis on the extracted samples, so as to judge whether the condenser hot well is leaking according to the content of metal ions in the samples. In the process of extracting samples, the power provided by the rotating motor 5 is used to drive the turntable 6 to rotate, so that the turntable 6 drives the connecting The connecting column 7 rotates, so that the connecting column 7 drives the movable frame 8 to move left and right periodically under the restriction of the limit seat 21, so that the movable frame 8 drives the scraper frame 9 to move left and right, thereby scraping off the filtered impurities and avoiding impurities from clogging the filter frame 4 as much as possible. When the sample is extracted, the worker opens the hydraulic rod 10, and uses the power provided by the hydraulic rod 10 to drive the sealing plate 12 to move to the side away from the hydraulic rod 10, thereby blocking the filter frame 4. Then the worker opens the sewage pipe 13 and the water inlet pipe 14, and adds water to the inside of the connecting box 3 through the water inlet pipe 14, thereby discharging impurities from the inside of the sewage pipe 13 and avoiding impurities from affecting the extraction of subsequent samples.
