Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a generator maintenance device. Background Art

[0002] Generators that purify water bodies by electrolyzing water will scale when used for a long time. A large amount of hard shells of calcium carbonate and magnesium carbonate will accumulate on the surface of the electrode of the generator, reducing the contact area between the electrode and the water body, seriously reducing the purification effect, and long-term scaling will shorten the service life of the generator. Therefore, it is necessary to regularly use citric acid solution to descale and maintain the generator.

[0030] like Figure 1 , 2 As shown in Figure 3, a generator maintenance device includes a maintenance vehicle 100 and a maintenance base station 200. The maintenance vehicle 100 and the maintenance base station 200 work together.

[0031] like Figure 1 , 2 3, the specific working process of the utility model is as follows: first, the acid solution of the required concentration is configured through the acid solution chamber 11 of the maintenance base station 200, and then the clean water and the acid solution are respectively injected into the maintenance tank of the maintenance vehicle 100, and the maintenance vehicle 100 moves to the location of the generator to maintain the generator; during maintenance, the generator is first immersed in the acid solution for pickling to remove the scale on the generator. After the scale is cleaned, the generator is immersed in clean water for cleaning to remove the acid solution on the generator, and the maintenance of the generator is completed; the maintenance vehicle 10 0 automatically returns to the maintenance base station 200, and discharges the clean water and acid waste liquid after maintenance into the waste liquid chamber 14 of the maintenance base station 200 to mix into acidic waste liquid. The waste liquid chamber 14 detects the pH value of the acidic waste liquid, and then the alkali liquid chamber 12 configures alkali liquid of corresponding concentration according to the pH value of the acidic waste liquid in the waste liquid chamber 14, and then discharges the alkali liquid into the waste liquid chamber 14 to neutralize the acidic waste liquid to finally form neutral waste liquid, and then discharges the neutral waste liquid into the discharge chamber 15, and finally discharges the neutral waste liquid through the discharge chamber 15.
