The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] It should be noted that when installing, traditional coal mine exhaust ventilation devices are often limited by the structure, space and convenience of the mine tunnel, and are fixed in a specific position. This fixity makes it impossible for the ventilation device to move with the deepening of mining or changes in the layout of the mine tunnel, thereby limiting the coverage of its ventilation effect. Ventilation dead corners and blind spots are "hotbeds" for the accumulation of harmful gases (such as carbon monoxide, methane, etc.) and dust. These harmful substances continue to accumulate in the mine tunnel, which not only poses a threat to the health of miners, but may also cause serious accidents such as explosions and fires; miners working in ventilation dead corners or blind spots are prone to fatigue, breathing difficulties, and even occupational diseases due to being in an environment with poor air quality for a long time. At the same time, these areas are also the concentration of safety hazards. Once an accident occurs, it will pose a serious threat to the life safety of the miners. In view of the above problems, a coal mine ventilation adjustment device is needed to solve the above problems;
[0023] In this embodiment, the base plate 1 is designed to be movable and removable, so that the entire ventilation and adjustment device can be easily moved in the mine tunnel to adapt to the depth of mining or changes in layout. This design breaks the limitation of the fixed position of the traditional ventilation device and greatly expands the coverage of the ventilation effect; the mounting shell 2 serves as the support and mounting platform of the entire device, and the mounting shell is firmly fixed on the base plate to provide protection and support for the internal components; the steering shaft 3 realizes the power transmission of the motor through two mutually meshing first bevel teeth 10 and the first motor 9, and the first motor 9 drives the steering shaft to rotate, thereby driving the ventilation shell 4 to adjust the direction. This design enables the ventilation shell to flexibly adjust the ventilation angle according to needs to avoid the formation of ventilation dead angles and blind spots; the ventilation shell 4 is provided with fan blades 8 inside to generate and guide wind flow; the air guide duct 5 is responsible for directing the wind flow to the area that needs ventilation; the driving mechanism is used to drive the rotating shaft 7 to rotate, thereby driving the fan blades 8 to rotate; this design ensures that the ventilation and adjustment device can continuously and stably generate wind flow.

In this way, when the second motor 12 is started, its power can be directly transmitted to the transmission shaft 13 to achieve effective power transmission; the second bevel gears 14 are respectively fixed on the bottom end of the transmission shaft 13 and one end of the rotating shaft 7, and they are meshed with each other. This design realizes the power transmission between the transmission shaft and the rotating shaft, that is, when the transmission shaft rotates, the power is transmitted to the rotating shaft 7 through the two meshing second bevel gears 14, thereby driving the fan blades 8 to rotate and generate wind flow.

[0035] In this embodiment, the limit bolt is arranged on the groove block, and its position should ensure that it can penetrate the plug-in block and form a threaded connection with the groove block or a part of the ventilation shell 4; the main function of the limit bolt is to enhance the connection strength between the groove block and the plug-in block, and prevent the plug-in block from falling out of the groove block when subjected to external force.
[0036] To sum up, through the design of the liftable and movable base plate 1, the ventilation adjustment device can be easily moved in the mine tunnel to adapt to the depth of mining or changes in the layout of the mine tunnel, thereby expanding the coverage of the ventilation effect and reducing the formation of ventilation dead corners and blind spots; the combination of the steering shaft 3 and the first motor 9 enables the ventilation shell 4 to flexibly adjust the ventilation angle, ensuring that the wind flow can accurately and efficiently cover every corner of the mine tunnel, improving the ventilation efficiency, and solving the problem of the current non-adjustable angle of the coal mine ventilation device.
