Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, and in particular relates to a mining wind window structure. Background Art

[0002] In mine operations, ventilation facilities are one of the indispensable equipment, which directly affects the life safety of the operators in the mine. It is necessary not only to ensure that the operators can breathe smoothly, but also to take the dust out of the mine to control the dust concentration. At present, the commonly used ventilation method is that the fan sends air from the outside into the deep of the mine, and then returns the air through the air duct in the mine, and a wind window is set at the opening of the air duct for blocking. The wind window blocking usually adopts a fence structure, but the existing wind window structure has the following problems in actual use: since the opening size of the fence cannot be adjusted, when the opening of the fence is too small, it will affect the return air efficiency; and when the opening of the fence is too large, or even without the fence, it will cause the ventilation volume of the air duct to be too large, thereby affecting the overall air circulation effect of the ventilation facilities; in addition, the adjustment of the wind window is different from the ordinary window adjustment, and the former requires more subtle adjustment to more accurately control the ventilation volume.

[0003] In view of the above problems, it is necessary to design a mine wind window structure with simple structure, low cost, used in the air duct opening in the mine and capable of more accurately adjusting the ventilation volume. To this end, the applicant has cleverly designed the technical solution. Utility Model Content
