In addition, the installation base plate 1 may be directly placed on the upper surface of the roof for installation.
When the louver is required to be opened or closed, the pushing plate 9 can be moved by controlling the extension and retraction of the hydraulic cylinder 3 (which can be controlled remotely or controlled by an electric wire or other means), the pushing plate 9 can push the left moving plate 71 and the right moving plate 72 to move forwards or backwards at the same time, so as to drive the left rotating plate 81 and the right rotating plate 82 to synchronously rotate, the left rotating plate 81 and the right rotating plate 82 can drive the louver window sash 5 to synchronously rotate, so that when the louver window sash 5 rotates to the vertical direction, the louver is in a completely opened state, when the louver rotates to the horizontal direction, the louver is in a completely closed state, and the above description of the louver structure is directed to the description of the louver in the closed state.
In designing, the rotating plates (including the left rotating plate 81 and the right rotating plate 82) may be designed to be small, so that the adjacent two rotating plates cannot interfere with each other during the rotation, but in this case, the accuracy of controlling the rotation of the blind may be low. Therefore, the rotating plates can be designed to be large, two adjacent rotating plates can be staggered mutually by a method, the specific method can be that the included angle between each rotating plate and the hinge shaft in the middle of the rotating plate is not a right angle, and the included angle between each rotating plate and the hinge shaft is designed to be the same, so that the two rotating plates can be staggered mutually, and the mutual interference in the rotating process can be avoided.
The windproof shell can play a better windproof role under the condition that the shutter is opened or closed, and the windproof shell can play a good waterproof and rainproof function under the condition that the shutter is closed: the front water baffle 431, the waterproof barrier strip 52 at the front end of the louver window sash 5 and the rear water baffle 441 are sequentially arranged from front to back and are sequentially attached, so that water can be prevented from entering the louver window sash 5 through an attached gap to the maximum extent; if a small amount of water enters the louver 5, the water will be gathered by the drainage guide groove 53 and then flow into the left guide groove and the rear guide groove from two ends respectively, and because the left guide groove and the rear guide groove are positioned outside the waterproof side wall, the water in the left guide groove and the rear guide groove can be discharged to the upper surface of the roof from the front and the rear, so that the water cannot enter the room. In addition, the present invention can perform a waterproof function even in a fully opened state when it is designed in the following manner: when the shutter is in the fully open state, the drainage channel 53 at the bottom of the front one of the two adjacent sashes 5 is located behind the waterproof barrier 52 of the rear one of the sashes 5. Therefore, the rainwater is collected and drained by the drainage channel 53 after falling vertically, and will not fall into the room.
Therefore, the shutter disclosed by the invention integrates hydraulic automatic control, wind prevention, water prevention, drainage and flow guide, and is simple in structure and multifunctional.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
