[0002] In daily life, the problem of sewer blockage often occurs, which brings a lot of trouble to our life. Food residues, hair, and thin threads are common causes of sewer blockage.

[0003] At present, the filtering devices on the market are very simple, with a small diameter and very shallow depth, and a single-layer filtering cover is provided. During use, it is very difficult for sewage to be quickly discharged at once. For the convenience of water discharge, users usually directly pull out the filtering device, so that floating objects and impurities will enter the sewer along with the water flow, thus causing sewer blockage. Some of the existing pool debris filtering devices on the market are installed above the drain outlet in the pool, and are often lost during actual use, thus failing to prevent foreign objects from entering the pipeline; the other part is installed below the pool, which can prevent foreign objects from entering the pipeline, but requires a large space, and is inconvenient for installation and maintenance, and is not suitable for narrow space places.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-6 , for the overall assembly structure of a sewer pipe filtering device of the present utility model, which includes: a tee main body 1, a filter basket assembly 2 disposed inside the tee main body, and a union assembly 3 threadedly connected to the lower port 101 of the tee main body. Among them, the filter basket assembly includes a filter basket main body 21 and a filter basket cover 22 rotatably connected to the filter basket main body through a screw assembly. Front end plates 23 and rear end plates 24 are integrally formed at both ends of the filter basket main body. The screw assembly includes a self-tapping screw 25 and a gasket 26 sleeved on the self-tapping screw. A through hole is provided on the rear end plate, and a screw post 27 is provided on the inner end face of the filter basket cover.
