Technical Field

[0001] This utility model relates to the field of mine ventilation technology, and in particular to a self-locking device for a rotary vane type ventilation window in a mine ventilation system. Background Technology

[0002] Mine ventilation is a crucial guarantee for safe production in mines. It delivers fresh air, dilutes and removes toxic and harmful gases and dust, and regulates the underground climate. The ventilation system consists of a ventilation network, equipment, and control facilities, including structures such as air doors, air bridges, and air windows. It maintains air quality in the working area using mechanical regulation or natural ventilation, ensuring that the oxygen concentration in the incoming airflow is not less than 20%. Air windows are ventilation structures with adjustable openings on windbreak walls. Currently, air windows are either fixed-airflow or pull-rope adjustable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 7 As shown, a self-locking device for a rotary vane type ventilation window in a mine ventilation duct includes a horizontal frame 1, a rotating rod 2, a side frame 3, louvers 4, a self-locking control operator 5, a connecting rod 6, a self-locking adjusting gear disk 7, and a louver linkage assembly 8. The horizontal frame 1 and the side frame 3 are fixed to form a door frame, and both the horizontal frame 1 and the side frame 3 are rectangular steel structures. One end of each rotating rod 2 is fixed to the louver linkage assembly 8 set in the side frame 3, and the other end is set in a rotating bearing in the corresponding side of the side frame 3. Each rotating rod 2 is fixed with a louver 4. A self-locking adjusting gear disk 7 is set on the side frame 3 where the louver linkage assembly 8 is installed. A self-locking control operator 5 is set on the self-locking adjusting gear disk 7. A connecting rod 6 fixed to the rotating rod 2 is set on the side of the self-locking control operator 5. The rotation angle of the louver 4 is controlled by operating the self-locking control operator 5 at the locking position on the self-locking adjusting gear disk 7. This utility model operates by using a self-locking control operator 5 in conjunction with a self-locking adjusting gear disk 7 and a louver linkage assembly 8. The self-locking control operator 5 and the self-locking adjusting gear disk 7 adjust the locking angle, which drives the rotation of the rotating rod 2. At the same time, the louver linkage assembly 8 drives the other rotating rods 2 to rotate, so that the louver 4 rotates at a certain angle to achieve the required airflow of the window. It has the characteristics of good applicability, strong stability, easy maintenance, and convenient use.

[0021] As a preferred embodiment, such as Figure 4As shown, the louver linkage assembly 8 includes a linkage plate 81, a linkage block 82, a locking seat 83, and a linkage shaft 84. The linkage plate 81 is vertically arranged inside the frame 3. The linkage plate 81 is movably connected to one end of the linkage block 82 via the linkage shaft 84. The other end of the linkage block 82 is fixed with the locking seat 83. One end of each rotating rod 2 is fixed to the locking seat 83. By adjusting the locking angle through the self-locking control operator 5 and the self-locking adjusting gear disk 7, the rotating rod 2 is driven to rotate, which in turn drives the linkage plate 81 to drive the other rotating rods 2 to rotate, thereby rotating the louver 4 to a certain angle to achieve the required airflow of the window.

[0022] As a preferred embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the self-locking adjusting gear disk 7 includes a gear disk 71; the gear disk 71 is provided with a through arc-shaped guide groove 73 and a gear engaging groove 72 corresponding to the guide groove 73 and arranged along the circumferential direction. The arc-shaped guide groove 73 requires less effort during operation; while the gear engaging groove 72 provides more stable engagement.

[0023] As a preferred embodiment, such as Figure 5 and Figure 6 As shown, the self-locking control actuator 5 includes an operating head 51, a connecting screw 52, ​​a locking nut 53, a self-locking sleeve 54, a compression spring 55, and a snap-fit ​​connector 56. The snap-fit ​​connector 56 and the compression spring 55 are housed within the self-locking sleeve 54. One end of the connecting screw 52 is fixed in the operating head 51, and the other end of the connecting screw 52, ​​fitted with the locking nut 53, is threaded into the internal thread of the opening of the self-locking sleeve 54. Rotation of the operating head 51 drives the rotation of the rotating rod 2, causing the louver 4 to rotate at a certain angle. The snap-fit ​​connector 56 then engages with the gear engagement groove 72, resulting in a more secure connection. Furthermore, this structure allows adjustment of the compression spring 55 based on the engagement force, achieved by adjusting the locking nut 53 and the connecting screw 52. The overall structure is easy to adjust and highly adaptable.

[0025] As a preferred embodiment, such as Figure 1 and Figure 3 As shown, the louver 4 is provided with a louver bending part 41 to reduce resistance loss; at the same time, it is used to adjust airflow, light or line of sight, enhancing the flexibility and functionality of the structure.

[0026] Although the specific embodiments of this utility model have been described and explained in detail above, it should be noted that various equivalent changes and modifications can be made to the above embodiments based on the concept of this utility model. As long as the resulting functions do not exceed the spirit covered by the specification, they should all be within the protection scope of this utility model.
