[0002] Mining ventilators are industrial equipment specifically designed for ventilation in mines. They ensure air circulation and safety within the mine. Mining ventilators encounter different mining conditions during operation, and these different conditions require different air volume requirements. Therefore, it is necessary to install appropriate air volume adjustment devices on the mining ventilators to meet these different air volume demands.

[0003] Traditional mine ventilation fan airflow regulating devices suffer from the drawback of the regulating plate, which becomes dirty and requires maintenance over time. However, the plate's inconvenience in disassembly increases the workload of maintenance. Therefore, we propose an improved mine ventilation fan airflow regulating device to address these issues.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a mine ventilation fan airflow regulating device, comprising an regulating cylinder 1. Connecting plates 2 are hinged to both the upper and lower ends inside the regulating cylinder 1. A second rotating shaft 11 is installed at the bottom end of the connecting plate 2 inside the regulating cylinder 1, and the second rotating shaft 11 extends to the bottom end of the regulating cylinder 1 and is fitted with a first bevel gear 7. A fixing seat 6 is provided on the outer wall of the first bevel gear 7, and the fixing seat 6 is fixed to one end of the regulating cylinder 1. A second bevel gear 8 is meshed at the bottom end of the first bevel gear 7. A first rotating shaft 9 is installed inside the second bevel gear 8, and a servo motor 10 is installed on one side of the first rotating shaft 9. Furthermore, the servo motor 10 is installed on one side of the fixed base 6, and the connecting plate 2 is equipped with an adjustment plate 5. The upper and lower ends of the surface of the adjustment plate 5 are fixed with limit seats 15. A fan 19 is installed on one side of the adjustment cylinder 1. Limit blocks 14 are hinged to the surface of the connecting plate 2. The limit seats 15 and the limit blocks 14 are compatible with each other and form a locking structure. The locking structure design facilitates the disassembly and installation of the connecting plate 2. Several limit seats 15 are provided, and the several limit seats 15 are symmetrically distributed in pairs about the central axis of the adjustment plate 5, so that the adjustment plate 5 is stably installed inside the connecting plate 2.

[0022] Specifically, such as Figure 1 and Figure 4As shown, when using this structure, if maintenance is required on the adjustment plate 5, the adjustment plate 5 should be disassembled first. During disassembly, the limiting blocks 14 on both sides of the front end of the adjustment plate 5 should be rotated out of the inside of the limiting seat 15. After the installation of the adjustment plate 5 is opened, the adjustment plate 5 can be disassembled from the inside of the connecting plate 2 for maintenance. After maintenance, the adjustment plate 5 should be aligned with the corresponding connecting plate 2 and spliced ​​together. The limiting blocks 14 should be rotated in reverse to engage with the inside of the limiting seats 15 on both sides of the front end of the adjustment plate 5. The maintained adjustment plate 5 can then be installed and used again.

[0023] One end of the outer wall of the regulating cylinder 1 is fixed with a mounting bracket 3, and each mounting bracket 3 is movably provided with a threaded rod 12. One end of each threaded rod 12 is equipped with a handle 4, and the other end of each threaded rod 12 is equipped with a mounting block 13. There are four sets of mounting brackets 3, and the four sets of mounting brackets 3 are distributed in a ring on the outer wall of the regulating cylinder 1, which makes the regulating cylinder 1 more stable on the outer wall of the mine ventilation fan.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, when using this structure, the air volume regulating device is first installed on the mine ventilation fan. During installation, the regulating cylinder 1 is engaged with one end of the fan 19 by the mounting bracket 3, and the threaded rod 12 is rotated in sequence to push the mounting block 13 to fit against the surface of the fan 19, so that the regulating cylinder 1 clamps the mine ventilation fan, and the air volume regulating device is installed at one end of the mine ventilation fan.

[0025] A protective net 17 is installed at the rear end inside the regulating cylinder 1, and a locking block 18 is fixed on the outer side wall of the protective net 17. A locking groove 16 is provided at the rear end inside the regulating cylinder 1. The cross-section of the locking groove 16 is larger than the cross-section of the locking block 18. The locking groove 16 and the locking block 18 form a locking structure. The design of the locking structure facilitates the installation, disassembly and maintenance of the protective net 17.

[0026] Specifically, such as Figure 4 As shown, when using this structure, the locking block 18 on the outer wall of the protective net 17 is aligned with the locking groove 16 inside the regulating cylinder 1 and engaged together, so that the protective net 17 is installed at one end inside the regulating cylinder 1. Before the mine ventilation fan brings the external air into the mine, it will be filtered by the protective net 17 to remove impurities before entering the mine. Subsequently, the protective net 17 can be pulled forcefully to one end, so that the locking block 18 moves out from inside the locking groove 16, thereby disassembling the protective net 17 for cleaning.

[0027] Working principle: In use, the regulating cylinder 1 is taken out and its mounting bracket 3 is engaged with one end of the fan 19. Then, the threaded rod 12 is rotated to push the mounting block 13 to fit against the surface of the fan 19, thereby clamping the regulating cylinder 1 onto the mine ventilation fan. This allows the air volume regulating device to be installed at one end of the mine ventilation fan. After installation, the servo motor 10 is started to drive the first rotating shaft 9 to rotate. The rotation of the first rotating shaft 9 drives the second bevel gear 8 to rotate. The rotation of the second bevel gear 8 drives the meshing first bevel gear 7 to rotate. The rotation of the first bevel gear 7, through the second rotating shaft 11 and the connecting plate 2, drives the internal mounting bracket... The adjusting plate 5 is rotated and adjusted to the required angle, thereby adjusting the air volume introduced by the mine ventilation fan installed at one end of the adjusting cylinder 1 to the required size. After a period of time, the limiting blocks 14 on both sides of the front end of the adjusting plate 5 can be rotated to rotate out of the inside of the limiting seat 15. After the adjusting plate 5 is installed, it can be disassembled from the inside of the connecting plate 2 for maintenance. After maintenance, the adjusting plate 5 is aligned with the corresponding connecting plate 2 and spliced ​​together. The limiting blocks 14 are rotated in reverse to lock into the inside of the limiting seats 15 on both sides of the front end of the adjusting plate 5. The maintained adjusting plate 5 is then installed and used again.
