Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

As shown in fig. 1, a guide rail 2 is arranged in a sewage pump station shell 1, a guide clamping plate 33 for limiting the movement on the guide rail is arranged on a filter frame 3, so that the filter frame 3 can move up and down along the guide rail 2, a pulling machine is connected with a lifting lug 32 at the upper end of the filter frame 3 by using a lifting rope, and the filter frame 3 is pulled to the top by the pulling machine for sundry cleaning; the sewage pump 7 is arranged at the bottom of the inner cavity of the sewage pump station shell 1, three water inlets 6 are arranged on the side wall of the sewage pump station shell 1, and the inner ends correspond to the filter frames 3, so that the entered sewage passes through the filter frames 3, and the filter frames 3 filter impurities with larger volume, so that the damage to the sewage pump 7 is avoided; the sewage pump 7 is connected with a drain pipe 8, and the drain pipe 8 extends to the outer side from the middle part of the sewage pump station shell 1;
