Example one

Referring to fig. 1-2, the present invention provides a protective ventilation window, which includes a frame 2; the middle part of the area enclosed by the frame 2 is a hollow part; the frame 2 is fixedly connected with a plurality of water bars 8 which are transversely arranged, the plurality of water bars 8 are arranged along the height direction of the frame 2, and the plurality of water bars 8 can shield the hollow part; the water retaining strips 8 are obliquely arranged downwards, and an overlapping area is formed between every two adjacent water retaining strips 8.

The overlapping area is that the lower edge of the high-position water retaining strip 8 in the adjacent water retaining strips 8 covers the upper edge of the low-position water retaining strip 8.

The overlapping area can prevent water spray and water jet from passing through the water retaining strip 8 at any angle. The water bars 8 arranged in a plurality of pieces can also isolate foreign matters to prevent the foreign matters from entering.

The water bar 8 comprises an inclined plate 3; two side edges of the inclined plate 3 are respectively fixed with a connecting plate which is vertically arranged, and the two connecting plates and the inclined plate 3 are formed into a Z shape.

The joint plate is divided into a first joint plate 4 and a second joint plate 5. In the installation of the water bar 8, the first connecting plate 4 faces upwards, and two ends of the first connecting plate are fixed on the frame 2; the second connecting plate 5 is a free end, and the second connecting plate 5 is arranged downwards. The overlapping area is specifically explained by taking the adjacent water bars 8 as a unit, the second connecting plate 5 of the high-position water bar 8 (i.e. the water bar 8 at the higher position) covers the low-position water bar 8 (i.e. the water bar 8 at the lower position), so that water spray and water spray at any angle are blocked by the inclined plate 3 and the second connecting plate 5 when the water spray and the water spray irradiate towards the water bar 8, and then the water flows downwards. This prevents the water from directly striking through the water bar 8.

The frame 2 is fixed with a dustproof grid 7 corresponding to the water bar 8, a gap is formed between the dustproof grid 7 and the frame 2, and the water bar 8 is arranged in the gap.

The upper part of the frame 2 and the upper part of the gap can be further provided with a dustproof grid 7, and the dustproof grid 7 mainly comprises a grid and a filtering layer filled in the grid. The dust-proof mesh 7 prevents the entry of particles and dust.

The water retaining strip 8 at the lowest part and the frame 2 form a drainage channel 1; a water guide plate 6 is arranged in the gap corresponding to the water bar 8, the water guide plate 6 is arranged between the dustproof grid 7 and the water bar 8, a folded plate is formed at the bottom edge of the water guide plate 6, and the folded plate extends into the drainage channel 1. The running water impacting the water bar 8 can be adhered on the water guide plate 6 and is drained outwards through the drainage channel 1 by the drainage of the water guide plate 6 and the folded plate.
