[0001] This invention relates to the field of louver technology, specifically to a dustproof louver device. Background Technology

[0002] Chinese patent document with application number 201621062167.1 discloses a three-layer stacked louvered window for a generator set container, employing a combination of a diamond dustproof mesh, fixed noise-reducing louvers, and motorized louvers. It includes an outer layer, a middle layer, and an inner layer. The outer layer is equipped with a diamond dustproof mesh; the middle layer has fixed noise-reducing louvers, which include a fixed louver frame and louvers; the inner layer has motorized louvers, which include a motorized louver mounting sleeve, a motorized louver frame, aluminum alloy blades, a motorized transmission rod, and a push rod motor. The motorized transmission rod is positioned between the motorized louver frame and the aluminum alloy blades, and a push rod motor is located in the middle of the motorized transmission rod. The push rod motor is located on both sides inside the motorized louver mounting sleeve and is electrically connected to an external controller. This three-layer stacked louvered window for the generator set container has the following shortcomings: 1) The aluminum alloy blades inside the frame of the electric louvered window are linked and open and close simultaneously, which cannot meet the requirements of partial opening and closing and has poor adaptability. 2) The diamond dustproof mesh is set on the outer layer. On the one hand, it is easily corroded by the external environment and has a short service life. On the other hand, it is easy to trap sand, causing blockage and affecting the breathability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dustproof louver device that can meet the requirements of partial opening and closing, has strong adaptability, improves the service life of the dustproof net, and has good air permeability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A dustproof louver device includes a window frame, a dustproof net, a movable louver layer, and a fixed louver layer. The dustproof net is located on the inner side of the window frame, the fixed louver layer is located on the outer side of the window frame, and the movable louver layer is located inside the window frame and between the dustproof net and the fixed louver layer. The movable louver layer includes multiple mounting frames arranged vertically adjacent to each other. Each mounting frame is provided with a movable louver for opening and closing the mounting frame, and each movable louver is independently connected to a drive mechanism for driving the opening and closing action of the movable louver.

[0005] As a further improvement to the above technical solution: The movable louver includes multiple movable blades, each of which is rotatably mounted within the mounting frame and connected to the drive mechanism.

[0006] Each of the aforementioned movable blades is arranged vertically at intervals and extends horizontally.

[0007] The movable blade is provided with a rotating shaft at both ends, and the rotating shaft is rotatably engaged with the inner side of the mounting frame.

[0008] The driving mechanism includes a vertical rack and a driving assembly. The vertical rack is mounted on the mounting frame and the rotating shaft is equipped with a gear that meshes with the vertical rack. The driving assembly is used to drive the vertical rack to move up and down, thereby causing the movable blades in the mounting frame to rotate synchronously up and down to open and close the mounting frame.

[0009] The drive assembly includes a reel and a pull cable. The reel is mounted on a mounting frame or window frame. A fixed pulley is provided at the top of the mounting frame. The pull cable is wound around the reel, passes over the fixed pulley, and is connected to a vertical rack. A rotating handle is provided on the reel, and a locking element is provided on the rotating handle for locking with the reel.

[0010] The outer side of the reel is provided with locking holes spaced around the rotation center of the reel, and the locking element is a locking screw for inserting into the locking holes to lock the rotating handle and the reel.

[0011] The fixed louver layer is provided with sand discharge grooves in the middle and at the bottom, and the sand discharge grooves are arranged corresponding to the bottom of a mounting frame.

[0012] The bottom of the mounting frame corresponding to each of the sand discharge channels is provided with a guide slope for guiding the sand discharge channel.

[0013] The mounting frame is square.

[0014] Compared with the prior art, the advantages of this utility model are: The dustproof louver device of this utility model has two advantages. First, since each movable louver is independently connected to a drive mechanism for driving the opening and closing of the movable louvers, it means that each mounting frame can be opened and closed independently as a part, which can meet the requirements of partial opening and closing and has strong adaptability. Second, the dustproof net is set on the inner side of the window frame and is set on the outer side. On the one hand, it is not easily corroded by the external environment, which improves its service life. On the other hand, it is not easy for sand to enter and cause blockage, and it has good ventilation performance. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Figures 1 to 3This invention illustrates an embodiment of a dustproof louver device. The dustproof louver device of this embodiment includes a window frame 1, a dustproof net 2, a movable louver layer 3, and a fixed louver layer 4. The dustproof net 2 is located inside the window frame 1, the fixed louver layer 4 is located outside the window frame 1, and the movable louver layer 3 is located inside the window frame 1 and between the dustproof net 2 and the fixed louver layer 4. The movable louver layer 3 includes multiple mounting frames 31 arranged vertically adjacent to each other. Each mounting frame 31 is provided with movable louvers 32 for opening and closing the mounting frame 31. Each movable louver 32 is independently connected to a drive mechanism 33 for driving the opening and closing action of the movable louver 32.

[0024] This dustproof louver device has two advantages. First, since each movable louver 32 is independently connected to a drive mechanism 33 for driving the opening and closing of the movable louver 32, it means that each mounting frame 31 can be opened and closed independently as a part, which can meet the requirements of partial opening and closing and has strong adaptability. Second, the dustproof net 2 is located on the inner side of the window frame 1, which is relatively located on the outer side. On the one hand, it is not easily corroded by the external environment, which improves its service life. On the other hand, it is not easy for sand to enter and cause blockage, which has good ventilation performance.

[0025] Furthermore, in this embodiment, the movable louver 32 includes multiple movable blades 321, each of which is rotatably disposed within the mounting frame 31 and connected to the drive mechanism 33. The drive mechanism 33 drives each movable blade 321 to synchronously flip upward to the open position to open the mounting frame 31 and improve air permeability; conversely, it drives each movable blade 321 to synchronously flip downward to overlap and close the mounting frame 31.

[0026] Furthermore, in this embodiment, the movable blades 321 are arranged vertically at intervals and extend horizontally. Preferably, the movable blades 321 are square, and when closed, the lower side of the upper movable blade 321 overlaps the upper side of the lower movable blade 321.

[0027] Furthermore, in this embodiment, the two ends of the movable blade 321 are respectively provided with a rotating shaft 34, and the rotating shaft 34 is rotatably engaged with the inner side of the mounting frame 31.

[0028] Furthermore, such as Figure 2 As shown, in this embodiment, the drive mechanism 33 includes a vertical rack 331 and a drive assembly. The vertical rack 331 is raised and lowered on the mounting frame 31. The rotating shaft 34 is provided with a gear 35 that meshes with the vertical rack 331. The drive assembly is used to drive the vertical rack 331 to move up and down, thereby driving each movable blade 321 in the mounting frame 31 to rotate up and down synchronously to open and close the mounting frame 31.

[0029] Furthermore, in this embodiment, the drive assembly includes a reel 332 and a pull cable 333. The reel 332 is mounted on the mounting frame 31 or the window frame 1. The top of the mounting frame 31 is provided with a fixed pulley 36. The pull cable 333 is wound around the reel 332, passes over the fixed pulley 36, and connects to the vertical rack 331. The reel 332 is provided with a rotating handle 334, and the rotating handle 334 is provided with a locking member 335 for locking with the reel 332. When the vertical rack 331 is not subjected to the tension of the pull cable 333, each movable blade 321 remains in the open state with its flipped-up position. When the reel 332 winds up the pull cable 333 and pulls the vertical rack 331 upward, each movable blade 321 is driven downward to the closed state through each gear 35. At this time, the locking member 335 locks the rotating handle 334 and the reel 332, maintaining each movable blade 321 in the closed state. Alternatively, the reel 332 can tighten the vertical rack 331 via the pull wire 333, keeping the vertical rack 331 in a high position. At this time, the movable blades 321 are in a downward-folded closed state. When the tension of the pull wire 333 is released from the reel 332, the vertical rack 331 rises under its own weight and drives the movable blades 321 to flip up to the open state via the gears 35. Of course, in other embodiments, the drive mechanism 33 can also be a conventional structure in the prior art, such as the electric drive structure for driving aluminum alloy blades in application number 201621062167.1.

[0030] Furthermore, in this embodiment, the outer side of the winding reel 332 is provided with locking holes 336 spaced apart around the rotation center of the winding reel 332. The locking member 335 is a locking screw for inserting into the locking holes 336 to lock the rotating handle 334 and the winding reel 332. The locking member 335 is inserted into different locking holes 336 to lock different states of the movable blade 321, such as locking the movable blade 321 in the closed state, or locking the movable blade 321 in the open state.

[0031] Furthermore, in this embodiment, the fixed louver layer 4 is provided with sand discharge grooves 5 in the middle and at the bottom, and the sand discharge grooves 5 are arranged correspondingly to the bottom of a mounting frame 31. The sand discharge grooves 5 facilitate the discharge of sand and dust that enters the interior. Of course, they can also be omitted. Alternatively, sand can be discharged by providing sand discharge holes at the bottom.

[0032] Furthermore, in this embodiment, the bottom of the mounting frame 31 corresponding to each sand discharge trough 5 is provided with a guide slope 6 for guiding the sand discharge trough 5. The guide slope 6 is used to guide the sand and dust that falls due to being blocked by the movable blade 321 to the corresponding sand discharge trough 5 for discharge.

[0033] Furthermore, in this embodiment, the mounting frame 31 is square. Preferably, the window frame 1 is also square.

[0034] Furthermore, in this embodiment, the fixed louver layer 4 is an existing structure, such as including multiple fixed blades, which can be arranged horizontally at intervals and in a horizontal tilting state, or arranged vertically at intervals and in a vertical tilting state.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
