Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically to an adaptive adjustable grille device. Background Technology

[0002] Bar screens are widely used in ventilation systems, water treatment equipment, material conveying channels, and other applications. They primarily function to guide fluid flow, filter impurities, or block materials through fixed or movable bar screens. Traditional bar screens suffer from the following technical challenges;

[0003] Most bar screens have independently adjustable movable bars, which can easily lead to inconsistent bar angles during manual adjustment, resulting in uneven flow resistance and reduced filtration accuracy. Traditional bar screens rely heavily on manual adjustment, which is difficult and inefficient for large equipment or special scenarios such as high altitudes or underwater environments. Furthermore, it is difficult to dynamically respond to real-time operating conditions. In addition, the power transmission structure of some adjustable bar screens is poorly designed, which can easily lead to jamming and wear, resulting in reduced adjustment accuracy and even affecting the safe operation of the equipment due to transmission failure. In view of this, we propose an adaptive adjustable bar screen device to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive adjustable grid device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive adjustable grille device, comprising a fixed frame, a filter screen, a swing mechanism, and an adjustment mechanism. The fixed frame is provided with a filter screen and has an installation groove. The installation groove is provided with a linkage-driven swing mechanism, and a gear-driven adjustment mechanism is fixedly connected to one side of the swing mechanism in the installation groove.

[0006] Preferably, the swing mechanism includes a swing plate, a swing rod, a linkage rod, a movable shaft, an adjusting handle, a swing frame, a limiting block, and a transmission wheel. Multiple swing plates are equidistantly connected within the fixed frame. A swing rod is fixedly connected to each swing plate within a mounting groove. A movable shaft is provided on the swing rod. The swing rod is movably connected to the linkage rod via the movable shaft. A swing frame is fixedly connected within the mounting groove. An adjusting handle is provided on one side of the swing rod and the swing frame.

[0007] Preferably, a limit block is fixedly connected to the adjusting handle, the limit block is located on the swing frame, and a transmission wheel is fixedly connected to one side of the limit block.

[0008] Preferably, the adjustment mechanism includes a mounting frame, a guide rod, a threaded rod, a drive motor, an adjustment block, and an arc-shaped rack. The mounting frame is fixedly connected in the mounting groove. The mounting frame is provided with a guide rod and a threaded rod. The drive motor is fixedly connected to one side of the mounting frame. The output end of the drive motor is fixedly connected with a threaded rod. The adjustment block is provided with a threaded structure. The adjustment block and the threaded rod cooperate with each other, and the adjustment block is located on the guide rod.

[0009] Preferably, an arc-shaped rack is fixedly connected to the upper side of the adjusting block, and the arc-shaped rack and the transmission wheel mesh with each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Each swing plate is connected to a corresponding swing rod in the mounting slot of the fixed frame. When the swing rod rotates, the swing plate will swing synchronously with it, changing the relative angle with the fixed frame. All swing rods are movably connected to the same linkage rod through the movable shaft, connecting multiple swing rods into a whole. When one of the swing rods is rotated by force, it will push or pull the other swing rods to rotate synchronously through the linkage rod, ultimately achieving the same angle and direction of swing of all swing plates.

[0012] 2. The drive motor fixed on one side of the mounting bracket is the power source of the entire adjustment mechanism. Its output shaft is fixedly connected to the threaded rod. The threaded rod and the adjustment block form a screw drive structure through threaded engagement. The adjustment block has an internal thread that matches the external thread of the threaded rod. The precise rotation of the threaded rod can achieve precise displacement control of the adjustment block, ensuring the accuracy of subsequent angle adjustment. The arc-shaped rack fixed on the upper side of the adjustment block meshes with the transmission wheel of the swing mechanism to form a gear transmission pair. When the adjustment block moves linearly along the guide rod, the arc-shaped rack moves synchronously with it, driving the transmission wheel to rotate through tooth surface meshing. Since the curvature of the arc-shaped rack matches the rotation trajectory of the transmission wheel, the smoothness of the meshing process can be ensured, avoiding jamming. When the transmission wheel rotates, all swing rods rotate synchronously, ultimately driving multiple swing plates in the fixed bracket to swing at the same angle, completing the automatic adjustment of the grid gap or angle.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0019] like Figures 1-4 As shown, the adaptive adjustable grille device proposed in this utility model includes a fixed frame 1, a filter screen 2, a swing mechanism 3 and an adjustment mechanism 4. The filter screen 2 is provided in the fixed frame 1, and an installation groove 5 is provided in the fixed frame 1. The swing mechanism 3 with linkage drive is provided in the installation groove 5, and the gear drive adjustment mechanism 4 is fixedly connected to one side of the swing mechanism 3 in the installation groove 5.

[0020] In an optional embodiment, the swing mechanism 3 includes a swing plate 301, a swing rod 302, a linkage rod 303, a movable shaft 304, an adjusting handle 305, a swing frame 306, a limiting block 307, and a transmission wheel 308. Multiple swing plates 301 are equidistantly connected within the fixed frame 1. A swing rod 302 is fixedly connected to the swing plate 301 within the mounting groove 5. A movable shaft 304 is provided on the swing rod 302. The swing rod 302 is movably connected to the linkage rod 303 through the movable shaft 304. A swing frame 306 is fixedly connected within the mounting groove 5. An adjusting handle 305 is provided on one side of the swing rod 302 and the swing frame 306.

[0021] In an optional embodiment, a limiting block 307 is fixedly connected to the adjusting grip 305, the limiting block 307 is located on the swing frame 306, and a transmission wheel 308 is fixedly connected to one side of the limiting block 307.

[0022] Each swing plate 301 is connected to a corresponding swing rod 302 in the mounting slot 5 of the fixed frame 1. When the swing rod 302 rotates, the swing plate 302 will swing synchronously with it, changing the relative angle with the fixed frame 1. All swing rods 302 are movably connected to the same linkage rod 303 through the movable shaft 304, connecting multiple swing rods 302 into a whole. When one of the swing rods is rotated by force, it will push or pull the other swing rods to rotate synchronously through the linkage rod, ultimately realizing that all swing plates 301 swing at the same angle and in the same direction.

[0023] In an optional embodiment, the adjustment mechanism 4 includes a mounting frame 401, a guide rod 402, a threaded rod 403, a drive motor 404, an adjustment block 405, and an arc-shaped rack 406. The mounting frame 401 is fixedly connected in the mounting groove 5. The guide rod 402 and the threaded rod 403 are provided on the mounting frame 401. The drive motor 404 is fixedly connected to one side of the mounting frame 401. The output end of the drive motor 404 is fixedly connected to the threaded rod 403. The adjustment block 405 is provided with a threaded structure. The adjustment block 405 and the threaded rod 403 cooperate with each other, and the adjustment block 405 is located on the guide rod 402.

[0024] In an optional embodiment, an arc-shaped rack 406 is fixedly connected to the upper side of the adjusting block 405, and the arc-shaped rack 406 and the transmission wheel 308 mesh with each other.

[0025] The drive motor 404 fixed on one side of the mounting bracket 401 is the power source of the entire adjustment mechanism. Its output shaft is fixedly connected to the threaded rod 403. The threaded rod 403 and the adjusting block 405 form a screw drive structure through threaded engagement. The adjusting block 405 has an internal thread that matches the external thread of the threaded rod 403. The precise displacement control of the adjusting block 405 can be achieved through the precise rotation of the threaded rod 403, which ensures the accuracy of subsequent angle adjustment.

[0026] The arc-shaped rack 406 fixed on the upper side of the adjusting block 405 meshes with the transmission wheel 308 of the swing mechanism 3 to form a gear transmission pair. When the adjusting block 405 moves linearly along the guide rod 402, the arc-shaped rack 406 moves synchronously with it and drives the transmission wheel 308 to rotate through tooth surface meshing. Since the arc of the arc-shaped rack 406 matches the rotation trajectory of the transmission wheel 308, the smoothness of the meshing process can be ensured and jamming can be avoided. When the transmission wheel 308 rotates, all swing rods 302 rotate synchronously, which ultimately drives multiple swing plates 301 in the fixed frame to swing at the same angle, thus completing the automatic adjustment of the grid gap or angle.

[0027] The working principle of this utility model is as follows: When using this device, each swing plate 301 is connected to a swing rod 302 in the mounting groove 5 of the fixed frame 1. When the swing rod 302 rotates, the swing plate 302 will swing synchronously with it, changing the relative angle with the fixed frame 1. All swing rods 302 are movably connected to the same linkage rod 303 through the movable shaft 304, connecting multiple swing rods 302 into a whole. When one of the swing rods is rotated by force, it will push or pull the other swing rods to rotate synchronously through the linkage rod, ultimately realizing that all swing plates 301 swing at the same angle and in the same direction.

[0028] Meanwhile, the drive motor 404 fixed on one side of the mounting bracket 401 is the power source of the entire adjustment mechanism. Its output shaft is fixedly connected to the threaded rod 403. The threaded rod 403 and the adjusting block 405 form a screw drive structure through threaded engagement. The adjusting block 405 has an internal thread that matches the external thread of the threaded rod 403. The precise displacement control of the adjusting block 405 can be achieved through the precise rotation of the threaded rod 403, which ensures the accuracy of subsequent angle adjustment.

[0029] The arc-shaped rack 406 fixed on the upper side of the adjusting block 405 meshes with the transmission wheel 308 of the swing mechanism 3 to form a gear transmission pair. When the adjusting block 405 moves linearly along the guide rod 402, the arc-shaped rack 406 moves synchronously with it and drives the transmission wheel 308 to rotate through tooth surface meshing. Since the arc of the arc-shaped rack 406 matches the rotation trajectory of the transmission wheel 308, the smoothness of the meshing process can be ensured and jamming can be avoided. When the transmission wheel 308 rotates, all swing rods 302 rotate synchronously, which ultimately drives multiple swing plates 301 in the fixed frame to swing at the same angle, thus completing the automatic adjustment of the grid gap or angle.

[0030] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
