[0026] The upper end surface of the movable plate 107 is fixedly connected with a motor 108, and the motor 108 is in power connection with the threaded shaft 111. The motor 108 can drive the threaded shaft 111 to rotate, thereby driving the hard pipe 109 to extend into the sewage in the sewage well;

[0027] The upper end surface of the annular frame 100 is fixedly connected with a liquid pump 104, and the liquid pump 104 is fixedly connected with a liquid infusion pipe 105, and the liquid infusion pipe 105 is connected to the sewage tank of the sewage transport truck, so that the sewage can be pumped into the sewage tank;

[0028] A soft tube 106 is sealed between the hard tube 109 and the liquid pump 104 , and the soft tube 106 can extend into the groove 110 as the hard tube 109 moves downward;

[0029] The annular frame 100 is fixedly connected to four side plates 113, and each of the side plates 113 is rotatably connected to a universal wheel 114, so that the device can be moved to the upper side of the sewage well through the universal wheel 114;
