DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figs. 1 to 3This application provides a remotely controllable mine ventilation device, including a body 1. Several baffles 2 are hinged to the air inlet of the body 1. A connecting rod 3 is installed on one side of each baffle 2. An arc-shaped groove 4 is provided on the body 1, and the connecting rod 3 is slidably engaged within the arc-shaped groove 4. A threaded rod 5 is rotatably mounted on the body 1, and a moving block 6 is threadedly connected to the threaded rod 5. The moving block 6 is slidably engaged on the body 1. Several telescopic rods 7 are installed on the moving block 6, and the output end of the telescopic rod 7 is rotatably connected to the connecting rod 3. The device has three speed settings: 0 (8), 1 (9), and 2 (10). The speed adjustment of these settings is based on existing technology, meaning that pressing one of them automatically releases the previously pressed button. Pressing 0 (8) releases all the buttons, similar to the buttons on an electric fan. A rotating block 11 is threaded onto the threaded rod 5. When the rotating block 11 and the moving block 6 are moved forward by the threaded rod 5, the rotating block 11 sequentially contacts 0 (8), 1 (9), and 2 (10). When the rotating block 11 is moved backward, it contacts the main body 1.

[0020] In this embodiment, the threaded rod 5 rotates, thereby driving the movable block 6 sliding on the main body 1 to move. The telescopic rod 7 on the movable block 6 drives the connecting rod 3 on the baffle 2 to move. Under the guidance of the arc groove 4 and the cooperation of the telescopic rod 7, the forward-moving movable block 6 can drive the baffle 2 to rotate, thereby increasing the air inlet area of ​​the main body 1. When the threaded rod 5 rotates, the rotating block 11 is also driven to rotate, so that one side of the rotating block 11 can finally abut against the main body 1 on which the adjustment button is installed. Then, as the movable block 6 gradually increases the air inlet area, the rotating block 11 abuts against and presses the adjustment buttons 0, 1, and 2, thereby gradually increasing the wind speed of the main body 1, and finally achieving the purpose of adjusting both adjustment methods at the same time. Furthermore, when the rotating block 11 is driven to move backward, the threaded rod 5 reverses, allowing the rotating block 11 to abut against the body 1 on the other side. Thus, when there are more than three adjustment buttons (0, 8; 1, 9; and 2, 10), the rotating block 11 can first abut against the body 1 on the other side, rotate and move backward to the desired button position, and then the threaded rod 5 drives the rotating block 11 to rotate forward. This allows the rotating block 11 to be accurately pressed to the desired button position, without having to press and move backward one by one to adjust the reduced air intake, which would affect the lifespan of the buttons.

[0021] In some embodiments, in order to facilitate precise driving of the moving block 6 and the rotating block 11, a rotary drive device 12 is installed on the main body 1. The rotary drive device 12 may be a servo motor, and the output end of the rotary drive device 12 is connected to the threaded rod 5 for transmission.

[0022] In some embodiments, to reduce friction between the rotating block 11 and the body 1, a V-shaped bracket 13 is mounted on the body 1. Gear 0 (8), gear 1 (9), and gear 2 (10) are all mounted on the V-shaped bracket 13. When the rotating block 11 is driven backward, it abuts against the V-shaped bracket 13. Therefore, if gear 0 (8), gear 1 (9), gear 2 (10), and the V-shaped bracket 13 are damaged or experience severe friction, only the V-shaped bracket 13 needs to be replaced.

[0023] In some embodiments, to facilitate adjustment of the baffle 2, the thickness of the side of the baffle 2 closest to the connecting rod 3 is greater than that of the side furthest from the connecting rod 3. This means the baffle 2 does not need to be rotated to be completely parallel to close the air inlet of the body 1, thus facilitating the movement of the telescopic rod 7 and the connecting rod 3.

[0024] In some embodiments, to avoid collisions between the baffles 2, the sides of the baffles 2 are provided with rounded corners.

[0025] In some embodiments, to facilitate pressing the button by rotating block 11, rotating block 11 is provided with a chamfer in the forward direction.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
