[0003] During the use of the prior art axial flow fan in the coal mine, if the coal falling from the inner wall of the coal mine enters the inside of the fan, it will cause damage to the blades of the fan and increase the probability of failure of the fan. Not only that, but now The airflow blown by the technical fan can only flow along a straight line. However, the internal structure of the coal mine tunnel is complicated. If the straight-line airflow meets the turning of the tunnel, the conveying distance of the airflow will be shortened and the ventilation effect of the fan will be reduced.

Embodiment Construction
[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0028] Such as figure 1 As shown, a safety ventilation device with guiding function for coal mining includes a main body 3, and also includes two guiding mechanisms and two protective mechanisms, the two guiding mechanisms are respectively connected with the two ends of the main body 3, and the two The protective mechanisms are respectively arranged inside the two ends of the main body 3;
[0029] Through the protective function of the protective mechanism, the probability of coal entering the fan is reduced, the probability of fan failure is reduced, and the practicability of the fan is improved. Not only that, the control of the wind direction of the fan is...

The invention relates to safe ventilating equipment for coal mining and having a guide function. The safe ventilating equipment for the coal mining and having the guide function comprises a main bodyand further comprises two guide mechanisms and two protection mechanisms; each guide mechanism comprises a corrugated pipe, a steering ring and at least two power assemblies; each power assembly comprises a sliding rod, a driving unit, a driving block, a transmission rod, a connecting block, a connecting seat and two mounting plates; each protection mechanism comprises a supporting ring, a protecting net and at least two connecting assemblies; and each connecting assembly comprises a supporting casing pipe, a supporting rod, a spring, a strengthening block and a limiting rod. According to thesafe ventilating equipment for the coal mining and having the guide function, through the protection effect of the protection mechanisms, the probability that coal sheets enter a fan is reduced, and the probability that the fan is broken down is reduced; control on the air direction of the fan is achieved through the guide mechanisms, so that an air flow blown out by the fan can flow in the direction of a tunnel, the conveying distance of the air flow is prolonged, and the ventilating effect of the fan is improved.
Description
technical field [0001] The invention relates to the field of coal mining equipment, in particular to a safety ventilation device with guiding function for coal mining. Background technique [0002] Axial flow fans are very widely used, that is, the air flow in the same direction as the axis of the fan blades, such as electric fans, air conditioner external fans are axial flow fans, the reason why it is called "axial flow" is because the gas is parallel to the fan axis Flow and axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. The axial flow fans fix the position and move the air. The axial flow fans are mainly composed of fan impellers and casings. The structure is simple but the data requirements are very high. High, as a kind of coal mine production equipment, the axial flow fan plays an important role in coal mine ventilation and greatly improves the safety of coal mine production. [0003] During the use of the prio...
