Description

Outer wall drainage structure Technical Field The application relates to the field of building drainage, in particular to an outer wall drainage structure. Background The outer wall is an important wall structure of the building body, and has the functions of bearing a certain load, shielding wind and rain, preserving heat and insulating heat, preventing noise, preventing fire, and the like. The window body (comprising a window frame and a window sash) is arranged at the outer wall so as to increase indoor lighting, facilitate indoor personnel to watch outdoor scenery and the like. In rainy days, rainwater can fall into the recess of window frame lower limb department. Under the condition of smaller precipitation, the ponding in the groove at the lower edge of the window frame can be timely discharged through the drain hole of the window frame. However, under the condition of larger precipitation (such as typhoon weather), the drainage quantity of the drainage hole is limited, so that the accumulated water in the groove at the lower edge of the window frame overflows and flows into a room. Disclosure of Invention In order to reduce rainwater falling into a groove at the lower edge of a window frame, the application provides an outer wall drainage structure. The application provides an outer wall drainage structure, which adopts the following technical scheme: an outer wall drainage structure comprises a bracket, a rotating rod, a sliding rod and a water retaining sheet, The bracket is used for being connected to an outer wall, The rotating rod is rotationally connected with the bracket around the axis of the rotating rod, The sliding rod is parallel to the rotating rod, the sliding rod is connected with the bracket in a sliding way, the sliding direction of the sliding rod is perpendicular to the axis of the rotating rod, One end of the water retaining sheet is connected to the rotating rod, the water retaining sheet is wound outside the rotating rod, and the other end of the water retaining sheet is connected to the sliding rod. By adopting the technical scheme, the bracket is arranged at the windowsill position of the outer wall; in rainy days, especially under the condition of large precipitation, the sliding rod is pulled to expand the water retaining sheet, and the water retaining sheet shields the lower edge of the window frame or the whole window body, so that part or all of the water retaining sheet blocks rainwater falling to the lower edge of the window frame; after the rain potential is reduced or precipitation is stopped, the rotating rod is rotated to roll the water retaining sheet, so that lighting and sight are not affected. Preferably, the rotating rod comprises a rod shaft and a sleeve, The rod shaft is connected with the bracket, The rod sleeve is coaxially and rotatably connected with the outside of the rod shaft, sliding friction is generated between the inner periphery of the rod sleeve and the outer periphery of the rod shaft, The water retaining piece is connected to the rod sleeve, and the water retaining piece is wound outside the rod sleeve. Through adopting above-mentioned technical scheme, the in-process of pulling slide bar in order to expand the manger plate piece, frictional force, the effort of slide bar to the manger plate piece of the interior week of pole cover and the axle periphery for the manger plate piece is in the state of tightening, reduces the fold or the bending of manger plate piece, does benefit to the rainwater landing on the manger plate piece. Preferably, the utility model also comprises a winding wheel and a pull rope, The winding wheel rotates to connect with the bracket, the axis of the winding wheel is perpendicular to the sliding direction of the sliding rod, One end of the pull rope is connected to the winding wheel, the pull rope is wound outside the winding wheel, and the other end of the pull rope is connected to the sliding rod. By adopting the technical scheme, in rainy days, the winding wheel is rotated to wind the pull rope, namely the slide bar is pulled through the pull rope, and compared with the case that the slide bar is directly pulled by a hand, the scheme of the application is not limited by the length of an arm, and is convenient for shielding the whole window by using the water retaining sheet. Preferably, the winding wheel comprises a wheel shaft and a wheel disc, The wheel axle is connected with the bracket, The wheel disc is coaxially and rotatably connected with the outside of the wheel shaft, sliding friction is generated between the inner periphery of the wheel disc and the outer periphery of the wheel shaft, The stay cord is connected in the rim plate, the stay cord rolling is outside the rim plate. Through adopting above-mentioned technical scheme, rotate the bull stick in order to rolling breakwater's in-process, breakwater and slide bar to the effort of stay cord, the frictional force between rim plate inner periphery and the
