The screen pressing filter cover 3 is used for pressing a shielding screen 5 (a circular hole corresponding to the position of the building water leakage pipeline 4 is arranged on the shielding screen 5, and the diameter of the circular hole is matched with the inner diameter of the building water leakage pipeline 4) on the top surface of the stainless steel flange 1; the screen filter housing 3 includes: the filter screen flange 31 is used for pressing the shielding net 5, and the filter cylinder 32 is coaxially welded on one side surface of the filter screen flange 31 far away from the shielding net 5, wherein the filter screen flange 31 is of a stainless steel ring structure, the inner diameter of the filter screen flange is larger than that of a building water leakage pipeline 4, the outer diameter of the filter screen flange is equal to that of the stainless steel flange 1, the outer diameter of the filter cylinder 32 is equal to that of the filter screen flange 31, and a plurality of filter holes 33 with the aperture of 3-8mm are uniformly distributed on the circumferential surface of the filter cylinder.
In the present embodiment, the inner diameter of the construction water leakage pipe 4 is 10cm; the outer diameter of the stainless steel flange 1 is 15cm, a waveguide tube mounting hole 10 with the aperture of 25mm is formed in the center position of the surface of the stainless steel flange 1, 6 waveguide tube mounting holes 10 with the aperture of 25mm are formed in the range of 10cm away from the center position at equal intervals along the circumferential direction (namely 7 waveguide tube mounting holes 10 are formed in the surface of the stainless steel flange 1), and the 6 waveguide tube mounting holes 10 are distributed in the range of 10cm away from the center position to the greatest extent, so that effective discharge of water and sundries in a 10cm area (namely in a building water leakage pipeline 4) is ensured, and effective shielding of electromagnetic waves in a building is ensured. Meanwhile, aiming at the conditions that the building roof is more in treatment flow, especially before waterproof treatment, various stones and crushed materials are more, the stones and the crushed materials with the thickness of more than 8mm are effectively filtered by adopting the screen pressing filter cover 3, so that the problem that the effective drainage of the building roof rainwater is seriously influenced due to the blockage of the stainless steel waveguide tube caused by the fact that the stones and the crushed materials enter the stainless steel waveguide tube along with the accumulated water is prevented. In addition, 6M 5 screw holes are uniformly arranged at intervals along the circumferential direction on the surface of the stainless steel flange 1 at a position 13cm away from the center of the stainless steel flange, so as to be used for connecting the shielding net 5 and the net pressing filter cover 3, thereby ensuring the compaction among the stainless steel flange 1, the shielding net 5 and the net pressing filter cover 3 and having better conductive connection.

It should be noted that, for the diameter of the stainless steel waveguide tube 2, if the diameter is too large, the stainless steel waveguide tube 2 installed within the range of 10cm of the diameter of the stainless steel flange 1 is too small, the space utilization rate is not high, and the water leakage effect is not good; if the water leakage effect is also affected if the water leakage effect is too small; for the length of the stainless steel waveguide tube 2, the length is required to be more than 9cm according to the design requirement that the shielding device is more than 60dB, so that the length of the stainless steel waveguide tube 2 is in the range of 9-20cm.
Because the inner diameter of the building water leakage pipeline 4 is about 10cm, the inner diameter of the net pressing flange 31 is required to be larger than 10cm; the screen flange 31 is used for fixing the shield screen 5 and the stainless flange 1, and it is necessary to have a fixing surface of 3cm, and to form a hole of M5 in the fixing surface. Therefore, the inner diameter of the screen flange 31 is typically 10-12cm; the outer diameter is 13-16cm, and the ring width of the screen flange 31 is 3-4cm. In the present embodiment, the screen flange 31 has an inner diameter of 11cm and an outer diameter of 15cm, and 6M 5 screw holes are uniformly spaced apart in the circumferential direction at a distance of 13cm from the center of the surface thereof.
