The working principle is as follows: when the novel full-lift sewage pump is used, as shown in fig. 1, the full-lift sewage pump is placed in a sewage pool to be conveyed and discharged, a power supply is switched on, the driving mechanism 16 is switched on, as shown in fig. 2 and 6, the driving mechanism 16 drives the second rotating shaft 17 to rotate through the meshing connection of the first fluted disc 5 and the second fluted disc 22, so that the first rotating shaft 4 and the impeller 6 thereon can be driven to rotate, thereby providing kinetic energy for sewage, further the sewage is continuously conveyed into the conveying pipeline 2, thereby the conveying and sewage discharging work is completed, when the operation fault causes the operation exceeding the rated lift range, as shown in fig. 3 and 5, the driving mechanism 16 generates heat exceeding the normal range, further the elastic air bag 13 is heated and expanded, and through the connection of the second sliding mechanism 14 between the device bin 12 and the second movable plate 15, when the elastic air bag 13 expands, the second movable plate 15 is driven to slide upwards, and meanwhile, through the sliding connection between the second rotating shaft 17 and the sleeve 18, the second movable plate 15 drives the sleeve 18 to move upwards until the second toothed disc 22 is disengaged from the first toothed disc 5, so that the driving mechanism 16 does not drive the impeller 6 to rotate any more, and the driving mechanism 16 is relieved from the overload state, at this time, because water is not conveyed any more, an operator can find the water in time and reasonably adjust the lift, meanwhile, after the driving mechanism 16 is cooled for a period of time, the temperature drops to a reasonable range, the elastic air bag 13 returns to a normal size, under the elastic action of the second spring 19, the second toothed disc 22 is re-engaged with the first toothed disc 5 to drive the impeller 6 to rotate again to work, so that the full-lift water pump can stop conveying water in time when working in a range exceeding the rated lift, thereby avoiding damage to the driving mechanism 16 caused by overheating and simultaneously reminding an operator to adjust the lift in time;

as shown in fig. 2 and 4, when the impeller 6 conveys the water flow by rotating, through the connection of the first sliding mechanism 9 between the water outlet bin 7 and the first movable plate 10 and the elastic action of the first spring 11, when the water flow impacts the first movable plate 10, the first movable plate 10 can be driven to move upwards, and the first sliding mechanism 9 is compressed, when the impeller 6 stops rotating, and the water flow does not impact the first movable plate 10 any more, through the elastic action of the first sliding mechanism 9, the first sliding mechanism 9 drives the first movable plate 10 to move downwards, so that the first movable plate 10 extrudes the water in the water outlet bin 7, and the water in the water outlet bin 7 is provided with certain kinetic energy by matching with the gravity action, and is sprayed out from the spray opening 8, so as to perform reverse impact on the filter screen on the working bin 1, and impurities blocked on the filter screen due to the forward impact of the water flow during the water flow conveyance can be reversely impacted on the filter screen on the working bin 1, thereby making it easier to fall off.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
