[0001] The invention belongs to the technical field of mine ventilation, and in particular relates to a ventilation system for non-coal mines and a use method thereof. Background Art

[0002] In the mining process, the ventilation system is an indispensable and important equipment. Its main function is to provide sufficient fresh air for the mine, dilute and remove harmful gases, dust and moisture in the mine, so as to ensure the health and safety of miners and the normal production of the mine. With the advancement of science and technology and the continuous improvement of mining technology, the ventilation system for non-coal mining has also experienced a development process from simple to complex, from manual to automatic.

[0015] A method for using a ventilation system for non-coal mining, comprising the following steps:

[0017] S2. Adjust the fan speed: The movement state of the ventilation door is fed back to the closed-loop controller in real time through the push rod and the control block. The closed-loop controller, as the intelligent core, calculates and outputs the corresponding control signal through a complex algorithm according to the opening size of the ventilation door.

[0020] S5. Continuous monitoring and optimization: The system continuously monitors the wind conditions and ventilation effects in the tunnel. Based on the monitoring results, the system automatically adjusts the ventilation door, fan speed and baffle angle to optimize the ventilation effect.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) Through the arrangement of the ventilation alley, the first servo motor, the driving rod, the driving gear, the transmission gear and the ventilation door, when in use, the driving gear drives the first connecting gears on both sides to rotate, and through the step-by-step transmission of the first connecting rod, the second connecting gear, the third connecting gear, the second connecting rod and the fourth connecting gear, the transmission gear is finally rotated. The rotation of the transmission gear drives the movable rod and the rotating rod at the bottom end thereof to rotate, thereby driving the ventilation door in the ventilation alley to open or close. The sliding rod slides in the arc groove, thereby ensuring the stable movement of the ventilation door, and through the cooperation of the sliding rod and the arc groove, the limiting and guiding functions of the ventilation door are realized, thereby improving the stability and reliability of the ventilation system, and also through the sophisticated transmission and limiting design, ensuring the stability and accuracy of the ventilation door during movement.

[0023] (2) Through the setting of the connecting rod, control rod, push rod, control block, closed-loop controller, control center, drive motor and fan blades, when in use, the installation clamp block is used in coordination with the control rod and the connecting clamp block, so that the entire control mechanism can flexibly respond to the control command, and the movement of the sliding block in the positioning groove, in conjunction with the elastic force of the extrusion spring, provides necessary limit and buffer for the movement of the ventilation door, thereby ensuring the reliability of the system. The push rod and the control block serve as the input end of the closed-loop controller, and feed back the movement state of the ventilation door to the closed-loop controller in real time. The closed-loop controller, as the intelligent core of the entire system, can accurately control the fan speed through the control signal according to the opening size of the ventilation door. Through the efficient communication and coordination between the closed-loop controller and the drive motor by the control center, after the drive motor receives the command from the control center, it drives the transmission wheel to rotate through the first transmission rod, and then drives the drive wheel to rotate through the first transmission belt. The rotation of the drive wheel finally drives the rotation of the second transmission rod and the fan blades, thereby realizing the opening and speed adjustment of the fan, thereby ensuring the air circulation efficiency and air quality in the mine, and providing a strong guarantee for the safe production of the mine.

[0024] (3) Through the setting of the monitor body, the mounting frame and the baffle, the monitor body is used to monitor and record the wind conditions entering the ventilation alley in real time. In order to achieve more intelligent ventilation management, the wind data collected by the monitor body is used to control the opening degree of the ventilation door, so as to dynamically adjust the ventilation volume according to the real-time wind conditions, to ensure that the air circulation in the alley is neither too strong nor too weak, and to achieve an ideal ventilation state. The positioning rod on the inner wall of the second connecting wheel rotates, and the positioning rod drives the baffle at the bottom to adjust the angle, thereby synchronously adjusting the angles of multiple baffles inside the mounting frame, so that the baffles are easy to control the direction of wind discharge, ensuring that the air in the alley can be discharged smoothly according to the predetermined path, further improving the overall efficiency of the ventilation system, so that the ventilation system can not only monitor the wind conditions in real time, but also dynamically adjust the opening degree of the ventilation door and the direction of wind discharge according to data feedback, providing comprehensive and precise control for the air circulation in the ventilation alley.

[0046] See also Figures 1 to 6 As shown, a method for using a ventilation system for non-coal mining includes the following steps:

[0047] S1. Control the switch of the ventilation door 14: through the drive of the first servo motor 2, the driving rod 3 drives the driving gear 4 to rotate, and the driving gear 4 then drives the first connecting gears 5 on both sides to rotate, and through a series of gears step by step, the transmission gear 11 is finally rotated, and the rotation of the transmission gear 11 drives the movable rod 12 and the rotating rod 13 at the bottom end to rotate, thereby driving the ventilation door 14 in the ventilation lane 1 to open or close.

[0048] S2. Adjust the fan speed: The movement state of the ventilation door 14 is fed back to the closed-loop controller 26 in real time through the push rod 24 and the control block 25. The closed-loop controller 26, as the intelligent core, calculates and outputs the corresponding control signal through a complex algorithm according to the opening size of the ventilation door 14.

[0050] S4. Adjust the baffles 46 to control the wind direction: At the exit of the ventilation tunnel 1, the angles of the multiple baffles 46 in the mounting frame 39 are adjusted by driving the second servo motor 40. The angle adjustment of the baffles 46 is achieved by the linkage of the second servo motor 40, the third transmission rod 41, the first connecting wheel 42, the second transmission belt 43, the second connecting wheel 44 and the positioning rod 5. The adjusted baffles 46 can control the direction of wind discharge, ensuring that the air in the tunnel is discharged smoothly along a predetermined path.

[0051] S5. Continuous monitoring and optimization: The system continuously monitors the wind conditions and ventilation effects in the tunnel. Based on the monitoring results, the system automatically adjusts the ventilation door 14, fan speed and baffle 46 angle to optimize the ventilation effect.

The first servo motor is fixedly installed on the inner top wall of the ventilation tunnel, and the drive rod and the drive gear are connected. According to the design requirements, the connecting gears, movable rods, ventilation doors and other components of various levels are installed to ensure that the transmission mechanism works normally. The monitor body is installed at the entrance of the ventilation tunnel to monitor the wind conditions in real time. The installation frame is installed at the exit of the ventilation tunnel, and the second servo motor, transmission belt, positioning rod, baffle and other components are fixed.

[0054] Start the first servo motor, drive the driving rod to drive the driving gear to rotate, the driving gear is transmitted step by step through a series of connecting gears, and finally drives the transmission gear to rotate. The rotation of the transmission gear drives the movable rod and the rotating rod at the bottom of it to rotate, thereby controlling the opening or closing of the ventilation door. According to the wind conditions monitored in real time by the monitor body, the system automatically adjusts the opening degree of the ventilation door to optimize the ventilation effect.

[0055] The closed-loop controller in the system calculates and outputs the corresponding control signal through a complex algorithm based on the movement state of the ventilation door (i.e. the degree of opening) and wind monitoring results. The control signal drives the drive motor to adjust the fan speed to keep the wind force in the alley within an appropriate range.

[0056] The second servo motor drives the baffle to rotate in the installation frame through the transmission belt and the positioning rod. According to actual needs, the angle of the baffle can be adjusted manually or automatically to change the direction and size of the wind force at the tunnel exit.

[0057] Monitor the ventilation system regularly, check the working status and wear of each component, replace or repair severely worn components in a timely manner to ensure long-term stable operation of the system, and adjust the layout and parameters of the ventilation system in a timely manner according to changes in mine mining progress and ventilation needs.

It not only improves ventilation efficiency and reduces energy consumption, but also effectively improves the working environment inside the mine and ensures the health and safety of miners. At the same time, the system has a high degree of intelligence and automation, which reduces manual intervention and improves work efficiency.

[0059] Working principle: When in use, the output end of the first servo motor 3 drives the driving rod 3 to rotate, and the driving rod 3 drives the driving gear 4 at the front end to rotate, and the driving gear 4 then drives the first connecting gears 5 on both sides to rotate, and through the step-by-step transmission of the first connecting rod 6, the second connecting gear 7, the third connecting gear 8, the second connecting rod 9 and the fourth connecting gear 10, the transmission gear 11 is finally rotated, and the rotation of the transmission gear 11 drives the movable rod 12 and the rotating rod 13 at the bottom thereof to rotate, thereby driving the ventilation door 14 in the ventilation alley 1 to open or close, and the installation clamp 18 cooperates with the control rod 19 and the connecting clamp 20, so that the entire regulating mechanism can flexibly respond to the control instructions. The movement of the sliding block 21 in the positioning groove 22, in conjunction with the elastic force of the extrusion spring 23, provides necessary limit and buffering for the movement of the ventilation door 14, ensuring the reliability of the system. The push rod 24 and the control block 25 serve as the input end of the closed-loop controller 26, and the movement state of the ventilation door 14 is fed back to the closed-loop controller 26 in real time. The closed-loop controller 26, as the intelligent core of the entire system, can calculate and output corresponding control signals through complex algorithms according to the opening size of the ventilation door 14, so as to realize precise control of the fan speed. The realization of this linkage mechanism benefits from the efficient communication and control between the closed-loop controller 26 and the drive motor 28 by the control center 27. After receiving the command from the control center 27, the driving motor 28 drives the driving wheel 30 to rotate through the first transmission rod 29, and then drives the driving wheel 32 to rotate through the first transmission belt 31. The rotation of the driving wheel 32 finally drives the rotation of the second transmission rod 33 and the fan blades 34, thereby realizing the opening and speed adjustment of the fan. The monitoring body 38 is to monitor and record the wind conditions entering the ventilation alley 1 in real time. In order to realize more intelligent ventilation management, the wind data collected by the monitoring body 38 is used to control the opening degree of the ventilation door 14, so as to dynamically adjust the ventilation volume according to the real-time wind conditions to ensure that the air circulation in the alley is neither too strong nor too weak. To achieve an ideal ventilation state, the output end of the second servo motor 40 drives the third transmission rod 41 to rotate, the third transmission rod 41 drives the first connecting wheel 42 at the top to rotate, the first connecting wheel 42 drives the second transmission belt 43 on the surface to rotate, the second transmission belt 43 drives the second connecting wheel 44 on the inner wall to rotate, so that the positioning rod 45 on the inner wall of the second connecting wheel 44 rotates, the positioning rod 45 drives the baffle 46 at the bottom to adjust the angle, thereby synchronously adjusting the angles of multiple baffles 46 inside the mounting frame 39, so that the baffle 46 is easy to control the direction of wind discharge, ensuring that the air in the alley can be discharged smoothly along the predetermined path, further improving the overall efficiency of the ventilation system.
