Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and specifically to a ventilation equipment for mining. Background Art

[0002] Mine ventilation refers to the input of fresh air into the mine to increase the oxygen concentration in order to dilute and remove toxic and harmful gases and dust in the mine. The basic tasks of mine ventilation are: to supply enough fresh air underground to meet the needs of personnel for oxygen; to dilute harmful gases and dust underground to ensure safe production; to regulate the underground climate to create a good working environment. Mine ventilation requires the use of high-power fans, and the airflow created by high-power fans is very strong, so the suction at the rear of the fan is also very strong. When the user passes by the rear side of the fan, there is a risk of being sucked in by the fan. Even if a barrier is set up, it is difficult to escape by oneself, resulting in the problem of a relatively low safety factor for the use of conventional high-power mine ventilators.

[0003] After searching, the Chinese patent announcement number is CN220451936U, which discloses a mine ventilation safety device. In the patent, when the device is used, if the user is unfortunately sucked, the user acts on the buckle frame to slide the buckle frame forward along the frame, so that the buckle frame unlocks the protective plate, and the protective plate slides into the inside of the frame, blocking the ventilation duct of the ventilator, reducing the suction force of the ventilator on the user, so that the user can escape smoothly with his own physical strength, thereby improving the safety factor during the use of the ventilator;

[0004] However, when the above device is used, the process of lowering the protective plate is cumbersome, so that it cannot effectively protect the staff who accidentally inhale, and it cannot effectively prevent the passage of solid waste, causing the ventilator to be easily damaged. Utility Model Content

[0005] The utility model proposes a mining ventilation device, which has the advantages of effectively protecting workers who accidentally inhale the ventilation device and automatically filtering solid impurities in the suction process, thereby increasing the service life of the fan. It solves the problems in the related technology that the process is complicated and cannot effectively protect workers who accidentally inhale the ventilation device in time and cannot filter solid impurities mixed in the suction process, resulting in a reduced service life of the fan.

[0010] Preferably, the circular plate moves back and forth within the inner cavity of the slide groove and the limit groove through a slider and a spring, and circular holes are evenly arranged on the rear side of the circular plate.

[0012] Preferably, the shape of the cross section of the circular plate matches the shape of the cross section of the inner cavity of the pipeline, so that when in use, the circular plate can be used to effectively filter solid impurities present in the sucked air.

[0013] Preferably, the cross rod, motor and fan blades are all located on the rear side of the inner cavity of the pipe, and the front side of the cross rod is away from the rear side of the inner cavity of the limit groove. Therefore, when in use, double protection is provided by the circular plate and the cross rod to prevent workers from being sucked into the pipe and quickly coming into contact with the fan blades, thereby preventing workers from being injured.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. The mining ventilation equipment uses a circular plate structure and a slider structure in coordination. If a worker is accidentally sucked into the inner cavity of the pipe during operation, the worker moves backward and contacts the circular plate and drives the circular plate backward under the action of the suction force, driving the slider to move backward in the inner cavity of the slide groove and the limit groove, so that the slider contracts and presses the second switch located in the inner cavity of the limit groove to turn off the motor and start the warning light. After that, the fan blades stop rotating, and there is no backward suction force in the inner cavity of the pipe, so that the worker can quickly walk out of the inner cavity of the pipe, thereby effectively protecting the worker who is accidentally inhaled into the ventilation equipment and automatically filtering the solid impurities in the suction process, thereby increasing the service life of the fan.

[0026] Working principle: When working, first assemble all the structures correctly, then start the motor 17 to drive the fan blades 18 to rotate, so as to suck the air in the front range of the inner cavity of the pipe 1. During the working process, the circular plate 11 and the circular hole 12 are used to filter the solid impurities mixed in the sucked air. After the staff manually turns off the motor 17 from time to time, the horizontal plate 14 is rotated, and the solid impurities adsorbed on the front surface of the circular plate 11 and the inner cavity of the circular hole 12 are scraped off by the cleaning strip 15. After the impurities are scraped off, they automatically fall into the inner cavity of the waste frame 5 under the arc design of the inner cavity of the pipe 1 for collection;

[0027] During operation, if the staff is accidentally sucked into the inner cavity of the working pipe 1, the staff moves backward and contacts the circular plate 11 and drives the circular plate 11 backward under the action of the suction force. As the circular plate 11 moves backward, the slider 10 also moves backward in the inner cavities of the slide groove 6 and the limit groove 7.

At this time, the fan blades 18 stop rotating, and the inner cavity of the pipe 1 no longer has a backward suction force. The staff can quickly walk out of the inner cavity of the pipe 1. After walking out, the staff presses the first switch 2 to turn off the warning light 3 and start the motor 17, so that the fan blades 18 rotate and continue to work.
