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.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figs. 1-2 This utility model provides an adjustable mine safety ventilation device, comprising:

[0035] The base 1 is equipped with a drive component and a control system 2. The control system 2 can be configured according to the specific usage environment. For example, it can be controlled by a microcontroller or by a PLC, ARM (Advanced RISC Machine), FPGA (Field Programmable Gate Array), etc. This embodiment does not make specific limitations.

[0036] A turntable assembly is rotatably connected to the base 1, and a drive assembly is used to drive the turntable assembly to rotate.

[0037] Fan 3, with a housing 4 installed at the air inlet end and an exhaust pipe 5 installed at the air outlet end; housing 4 is installed on the turntable assembly, with an air inlet pipe 6 installed at the end of housing 4 away from fan 3, and the air inlet pipe 6, exhaust pipe 5 and the inner cavity of housing 4 are interconnected.

[0038] Electric valve plate, the electric valve plate is installed inside the housing 4;

[0039] The filter assembly includes an activated carbon filter 7 and two metal filters 8. The activated carbon filter 7 is detachably connected between the two metal filters 8. The two metal filters 8 are arranged side by side with intervals, and both metal filters 8 can be detachably connected to the side of the housing 4 near the air inlet pipe 6.

[0040] Among them, the drive assembly, fan 3 and electric valve plate are all electrically connected to the control system 2;

[0041] With this configuration, the present invention drives the turntable assembly to rotate along the top of the base 1 through the drive assembly, thereby adjusting the installation position of the air inlet pipe 6. The air inlet direction of the fan 3 can be flexibly adjusted according to the actual needs of the mine, which can quickly adapt to the changes in the working face during the mining process, meet the dynamic ventilation needs, and make the ventilation more accurately target areas with high concentrations of harmful gases or large ventilation needs, thereby improving the flexibility and adaptability of the device and increasing the ventilation efficiency.

[0042] This utility model can quickly and efficiently filter the incoming mine air through activated carbon filter 7 and double-layer metal filter 8. Both activated carbon filter 7 and metal filter 8 are detachable, making them easy to clean or replace, thus reducing maintenance difficulty and cost.

[0043] This invention controls the opening and closing of the electric valve plate and adjusts its angle through the control system 2, thereby adjusting the opening angle as needed to regulate the air volume. In areas with high concentrations of harmful gases, the opening angle of the electric valve plate can be increased to increase the air volume, so as to quickly dilute and remove harmful gases. In areas with low ventilation demand, the opening angle of the electric valve plate can be reduced to reduce the air volume, avoid energy waste, achieve energy saving and consumption reduction, and further improve ventilation efficiency.

[0044] Further optimization of the solution includes the following electric valve plate:

[0045] Electric actuator 9 is installed on the top of housing 4; electric actuator 9 is electrically connected to control system 2;

[0046] Slider 10 is slidably connected to the top of housing 4, and slider 10 is fixedly connected to the telescopic end of electric actuator 9.

[0047] Two drive plates 12 are provided, and the two drive plates 12 are respectively installed on both sides of the slider 10. A rack is installed on the drive plate 12.

[0048] Two drive shafts 13 are provided, and the two drive shafts 13 are rotatably connected to the top wall of the housing 4. The bottom of the drive shaft 13 extends into the inner cavity of the housing 4. The top of the drive shaft 13 is equipped with a first gear 14, and the two first gears 14 mesh with two racks respectively.

[0049] Among them, the bottom of the drive shaft 13 is equipped with a valve plate body 21. Both valve plate bodies 21 are located inside the housing 4 and are arranged opposite to each other. The valve plate bodies 21 are slidably connected to the inner wall of the housing 4.

[0050] With this configuration, the electric actuator 9 is extended and retracted by the control system 2, which drives the slider 10 and the two drive plates 12 to move. The rack on the drive plate 12 meshes with the first gear 14 as it moves, thereby driving the first gear 14 and the drive shaft 13 to rotate. The valve plate body 21 connected to the bottom of the rotating drive shaft 13 moves relative to the housing 4, changing its opening or closing angle.

[0051] By precisely controlling the extension and retraction of the electric actuator 9 through the control system 2, the opening angle of the valve plate body 21 can be precisely adjusted. In areas with high concentrations of harmful gases, the opening angle of the valve plate body 21 is increased to increase airflow; in areas with low ventilation demand, the opening angle is decreased to reduce airflow.

[0052] Further optimization of the scheme: the turntable assembly includes a turntable body 15 rotatably connected to the top surface of the base 1, a gear ring 16 installed on the side wall of the turntable body 15, and a housing 4 installed on the top surface of the turntable body 15; the output end of the drive assembly meshes with the gear ring 16 for transmission.

[0053] The further optimized solution includes a drive motor 17 mounted on the base 1, the drive motor 17 being electrically connected to the control system 2, and a second gear 18 mounted on the output shaft of the drive motor 17, which meshes with the gear ring 16 for transmission.

[0054] With this configuration, the drive motor 17 is started by the control system 2. The output shaft of the drive motor 17 drives the second gear 18 to rotate. The second gear 18 meshes with the gear ring 16 installed on the side wall of the turntable body 15. The rotation of the gear ring 16 drives the entire turntable body 15 and its components such as the housing 4 and the fan 3 to rotate together on the top surface of the base 1. As the turntable body 15 rotates, the installation position of the housing 4 and the air inlet pipe 6 also changes, thereby realizing the flexible adjustment of the air inlet direction of the fan.

[0055] The design was further optimized by installing a slide rail 11 on the top of the housing 4, with the slider 10 slidably connected to the slide rail 11, ensuring the smoothness and accuracy of the electric valve plate adjustment process.

[0056] In a further optimized design, connecting wing plates 19 are installed on the two opposite inner side walls of the housing 4. The two drive shafts 13 are rotatably connected to the two connecting wing plates 19 respectively. The connecting wing plates 19 provide stable support points for the drive shafts 13, ensuring the stability of the drive shafts 13 and the valve plate body 21 on them during rotation.

[0057] The design was further optimized by installing support legs 20 at the four corners of the bottom surface of the base 1.
