In this embodiment, a cleaning machine is taken as an example to specifically describe the drainage working method, in this embodiment, three blockage detectors are arranged in a drainage pipe of the cleaning machine, one blockage detector is arranged at an inlet of the drainage pipe, the other blockage detector is arranged at an inlet of an arc-shaped section, and the other blockage detector is arranged at an outlet of the arc-shaped section. For the sake of convenience of the following description, the three clogging detectors are defined as a first clogging detector, a second clogging detector, and a third clogging detector, respectively, from the water inlet to the water outlet of the drain pipe. The drain pipe that the definition is located No. one jam detector upper reaches is divided into the A section, and the drain pipe that is located No. one between jam detector and No. two jam detectors is divided into the B section, and the drain pipe that is located No. two between jam detector and No. three jam detector is divided into the C section, and the drain pipe that is located No. three jam detector low reaches is divided into the D section.
After the cleaning machine has carried out cleaning, then control and carry out the drainage, the drain pipe does not have under the circumstances of blockking up, No. one blocks up the detector, No. two blocks up the detector, No. three blocks up the detector and can switch on in proper order, and the on-time difference of No. one blocks up detector and No. two and blocks up the detector and be comparatively fixed value, the standard time difference that No. one blocks up detector and No. two and blocks up the detector and switch on in this embodiment is T01, the on-time difference between No. two blocks up detector and No. three and blocks up the detector is comparatively fixed value, the difference standard time difference that No. two blocks up the detector and No. three blocks up the detector and switches on in this embodiment is T02. In the case of a drain pipe that is not blocked, it will correspond to a standard range of time durations for normal drainage. Therefore, at the beginning of drainage, if the first blockage detector, the second blockage detector and the third blockage detector are sequentially switched on, the time difference T1 between the first blockage detector and the second blockage detector is not more than T01, the time difference T2 between the second blockage detector and the third blockage detector is not more than T02, the first blockage detector, the second blockage detector and the third blockage detector are all in a switching-on state in the whole drainage process, and the total drainage duration T of the whole drainage process is within the standard drainage duration range, the situation that the drainage pipe is not blocked is judged. Wherein the total drain time period T for the entire drain process may be the time from when the first jam detector is turned on to when all jam detectors are turned off.

If the first blockage detector is in the state of disconnection, the second blockage detector and the third blockage detector are in the state of disconnection, the section B is judged to be seriously blocked. If the first blockage detector and the second blockage detector are both switched on, but the third blockage detector is switched off, the C section is judged to be seriously blocked. And under the condition that the drain pipe is seriously blocked, alarming the blocking position and the blocking degree to prompt a user to manually process the blockage of the drain pipe.
In the initial stage of drainage, if the first blockage detector, the second blockage detector and the third blockage detector are sequentially conducted, and the conduction time difference T1 of the first blockage detector and the second blockage detector is larger than T02, the blockage at the position A is judged, if T01 is larger than T1 and is smaller than or equal to 1.5T01, the section A in the drainage pipe is judged to be slightly blocked, and if 1.5T01 is larger than T1 and is smaller than or equal to 2T01, the section A in the drainage pipe is judged to be moderately blocked. If the first blockage detector, the second blockage detector and the third blockage detector are sequentially conducted, the conduction time difference T1 of the first blockage detector and the second blockage detector is not less than T01, and the conduction time difference T2 of the second blockage detector and the third blockage detector is more than T02, in this case, if T02 is more than T2 and not more than 1.5T02, the C section in the drain pipe is judged to be slightly blocked, and if 1.5T02 is more than T2 and not more than 2T02, the C section in the drain pipe is judged to be moderately blocked. According to the requirement, the conduction time difference between two adjacent jam detectors can be subdivided, and the different jam degrees are corresponded. According to different blockage degrees, the cleaning machine can be controlled to work according to different powers to perform forced drainage, and blockage is automatically eliminated by water flow. The forced drainage process can be carried out in the drainage process or independently after the drainage is finished.
In addition, after the water drainage is finished, whether the total water drainage time length T is within the standard time length range of normal water drainage is judged. If not, comparing the total drainage time T with drainage time thresholds S with different blockage degrees, and further judging the comprehensive blockage degree of the drainage pipe. The overall blockage level of the drain pipe can be determined by comparing the total drainage duration T with the drainage duration threshold S of different blockage levels.
If the blockage condition of non-serious blockage of the part in the drain pipe is judged in the drainage process, whether the whole blockage degree is consistent with the comprehensive blockage condition of each part is judged, if so, no blockage at other positions is judged, if not, namely, the whole blockage degree is greater than the comprehensive blockage condition of each part, the blockage of the section D is indicated, and the blockage degree of the section D is judged according to the comprehensive difference between the whole blockage degree and the blockage condition of each part.
The drainage working method can well determine the blocking position and the blocking degree in the drainage pipe, provides effective guidance for the dredging work of the drainage pipe, and is convenient for a user to dredge the drainage pipe.
Compared with the prior art, the drainage device and the drainage working method of the drainage device increase the number of the blockage detectors, so that the blockage position and the blockage degree in the drainage pipe can be accurately determined by acquiring the detection signals of the blockage detectors and the conduction time interval before the blockage detectors, the dredging strategy of the drainage pipe is convenient to set, on one hand, some conditions that the blockage is not serious can be autonomously treated by adjusting water flow parameters in the drainage pipe, and on the other hand, under the condition that the blockage is serious, a user or a maintenance person can conveniently carry out dredging treatment by adopting a more effective means according to the blockage position.
