In order to prevent the occurrence of the above-mentioned harmful phenomena, the existing technology will install a wall-attached wind tube above most tunneling machines to enhance ventilation and blow away the dust in the mining process in time; however, since the wind speed, wind direction, air volume and other parameters in the mine tunnel will change with the change of working conditions, if the air supply in the tunnel cannot be adjusted in time, it will lead to poor air supply effect. In severe cases, it may also cause the wind flow in the tunnel to reverse, causing dust to gather on the working surface, thereby seriously endangering the safety and health of the workers.

The entire adjustment process requires manual intervention or manual control of the machine to drive and adjust, which is inconvenient to operate, time-consuming and labor-intensive, and cannot respond flexibly according to changes in space and dust concentration in time, making the adjustment of wind direction and air volume prone to large errors and lags; 2. The accuracy and sensitivity of manual intervention or manual control of the machine to drive and adjust are not high, and it is impossible to achieve accurate control of air volume and direction and fast-response dynamic adjustment, and it is difficult to achieve better ventilation and dust control effects; 3. The scope of manual intervention or manual control of the machine to drive and adjust is limited, making it impossible for the wind direction and air volume in the tunnel to adapt to complex and changeable spaces, and the adaptability and flexibility of ventilation and dust control are poor.

[0028] The present invention sets a central controller to respectively control the dust concentration sensor, the first flow sensor, the second flow sensor, the air volume adjustment component 10, the first air duct component 20, the second air duct component 30, the rotating component 40 and the air outlet adjustment component 50 to work together. Compared with the existing ventilation method of manually or mechanically adjusting the air outlet direction or the air guide plate, the present invention does not need manual control of the machinery for driving and adjusting, so that the wind direction and air volume in the tunnel are convenient to adjust, saving time and labor, and can flexibly respond to changes in the space and dust concentration in the tunnel in a timely manner, avoiding large errors and lags in the adjustment of the wind direction and air volume; and the present invention also ensures the adjustment accuracy and sensitivity of the wind direction and air volume, effectively realizing the precise control of the air volume and wind direction and the fast response dynamic Adjustment can achieve better ventilation and dust control effects; the present invention expands the range of ventilation by arranging the first wind duct assembly 20 and the second wind duct assembly 30 to discharge air in multiple directions, so that the wind direction and air volume in the tunnel can adapt to the complex and changeable tunnel space, thereby ensuring the multi-directional supply of fresh air in the tunnel; the second wind duct assembly 30 is driven to rotate around the central axis of the second wind duct assembly 30 by arranging the rotating assembly 40, so that the airflow flowing out of the circulation port can form a cyclone, which further facilitates the rapid diffusion of fresh air, increases the coverage range and angle of the airflow, and can meet the ventilation needs of closed spaces of different shapes; the present invention has a simple structure and low cost, is easy to assemble and subsequently maintain, and is suitable for large-scale promotion and use in various underground closed spaces such as mines.

[0029] like Figure 1 As shown, the central axis of the gas outlet of the first wind tube assembly 20 is collinear with the central axis of the first wind tube assembly 20, the central axis of the second wind tube assembly 30 is parallel to the central axis of the first wind tube assembly 20, and the central axis of the flow port 31 is perpendicular to the central axis of the second wind tube assembly 30; the central axis of the first wind tube assembly 20 is parallel to the extension direction of the alley, so that the direction of the airflow blown out of the flow port 31 has an angle with the vertical direction.

[0030] By setting the specific structure of the first wind duct assembly 20 and the second wind duct assembly 30, the gas outlet of the first wind duct assembly 20 is parallel to the extension direction of the tunnel, ensuring the direct ventilation effect of the working face area, and the dust on the working face can be effectively controlled; by setting the flow port 31 on the second wind duct assembly 30 to form an angle with the vertical direction, the coverage range of the airflow is increased, and the dust in the tunnel can be more comprehensively controlled.

[0031] like Figure 1As shown, there are multiple dust concentration sensors, and the multiple dust concentration sensors are respectively arranged at intervals on the side walls of the working surface and the tunnel; when the dust concentration detected by the dust concentration sensor is within the set normal range, the central controller controls the state of the air volume adjustment component 10 to remain unchanged, and controls the rotating component 40 to drive the second air duct component 30 to rotate continuously. At this time, the flow rate in the first air duct component 20 is the first flow rate, and the flow rate in the second air duct component 30 is the second flow rate, and the first flow rate is not greater than the second flow rate; when the dust concentration detected by the dust concentration sensor exceeds the normal range, the central controller controls the air volume adjustment component 10 to work, increase the flow rate in the first air duct component 20, so as to reduce the dust concentration on the working surface; at this time, the flow rate in the first air duct component 20 is the third flow rate, and the flow rate in the second air duct component 30 is the fourth flow rate, and the third flow rate is respectively greater than the first flow rate and the fourth flow rate.

[0032] By setting up multiple dust concentration sensors and dynamic flow adjustment, the distribution of multiple sensors can be fully monitored, which can provide more comprehensive dust concentration information and ensure the effectiveness and timeliness of the dust control strategy; in a specific embodiment of the present invention, when the dust concentration exceeds the normal range, the central controller automatically adjusts the air volume adjustment component 10, preferentially increases the flow of the first air duct component 20, quickly responds to the high dust concentration on the work surface, and protects the working environment.

[0033] like Figure 1 As shown, the wind direction and air volume regulating device also includes a gas concentration sensor, which is electrically connected to the central controller and is used to detect the gas concentration in the tunnel; when the gas concentration detected by the gas concentration sensor is within a safe range, the central controller controls the state of the air volume regulating component 10 to remain unchanged, and controls the rotating component 40 to drive the second wind tube component 30 to rotate continuously; when the gas concentration detected by the gas concentration sensor exceeds the safe range, the central controller controls the air volume regulating component 10 to work, and increases the flow rates in the first wind tube component 20 and the second wind tube component 30 respectively, so as to dilute the gas concentration in the tunnel.

[0034] By setting up a gas concentration sensor, the gas concentration can be effectively monitored. The use of the gas concentration sensor provides safety monitoring for the tunnel and ensures the safety of the working environment. When the gas concentration exceeds the safe range, the central controller can adjust the air volume, increase the air to dilute the gas, and avoid potential safety accidents.

[0035] like Figure 1As shown, the air volume adjustment component 10 includes an adjusting air cylinder 11, an adapter 12, a first rotating structure and a second rotating structure. The inlet of the adjusting air cylinder 11 is connected to the external air cylinder. The adjusting air cylinder 11 has two outlets, one outlet is connected to the first air cylinder assembly 20, and the other outlet is connected to one end of the adapter 12, and the other end of the adapter 12 is connected to the second air cylinder assembly 30; the first rotating structure and the second rotating structure are rotatably arranged at the two outlets, respectively, the first rotating structure is used to control the air flow rate in the first air cylinder assembly 20, and the second rotating structure is used to control the air flow rate in the second air cylinder assembly 30; wherein the first rotating structure and the second rotating structure are electrically connected to the central controller respectively.

[0036] By setting up the air volume adjustment component 10, the first rotating structure and the second rotating structure can be precisely controlled, thereby realizing independent control of the air flow rate in the first air duct component 20 and the second air duct component 30 to meet different ventilation requirements; at the same time, the first rotating structure and the second rotating structure can be set to be uniformly managed by a central controller, thereby ensuring the coordination and efficiency of the air volume adjustment.

[0037] like Figure 1 As shown, the adapter 12 is an L-shaped tube, which includes a first tube and a second tube that are interconnected, and the central axis of the first tube is perpendicular to the central axis of the second tube; the first tube is connected to the outlet, and the second tube is connected to the second air duct assembly 30; wherein the central axis of the first tube is perpendicular to the central axis of the first air duct assembly 20, and the central axis of the second tube is colinear or parallel to the central axis of the second air duct assembly 30; the rotating assembly 40 is arranged on the second tube.

[0038] By setting the structure of the L-shaped tube adapter 12, the airflow distribution can be optimized. The design of the L-shaped tube optimizes the path of the airflow from the regulating duct 11 to the second duct assembly 30, thereby improving the efficiency and flexibility of the airflow distribution. At the same time, the L-shaped tube makes the second duct assembly 30 and the first duct assembly 20 more flexible in spatial layout, adapting to different alley environments, thereby improving spatial adaptability.

[0039] like Figure 1 As shown, the air outlet adjustment component 50 includes a connecting rod 51 and a plurality of air guide plates 52. The air guide plates 52 are rotatably arranged at the circulation openings 31, and the plurality of air guide plates 52 are arranged one by one corresponding to the plurality of circulation openings 31. The connecting rod 51 is respectively connected to the plurality of air guide plates 52 through ball joints. By moving the connecting rod 51, the rotation of the plurality of air guide plates 52 is adjusted at the same time, so as to adjust the airflow direction of the plurality of circulation openings 31 at the same time.

[0040] By setting up a ball joint connection between the connecting rod 51 and multiple air guide plates 52, the overall adjustment of the airflow direction of multiple flow ports 31 can be achieved, thereby improving the adjustment efficiency and consistency; at the same time, precise control of the airflow direction is achieved, thereby optimizing the ventilation effect of the second air duct assembly 30.

[0041] like Figure 1 As shown, the wind direction and air volume regulating device further comprises a filter, which is detachably disposed in at least one of the air volume regulating assembly 10, the first air cylinder assembly 20 and the second air cylinder assembly 30 for filtering the air flow.

[0042] By setting up a filter, the airflow can be purified, impurities in the airflow can be effectively removed, and the ventilation quality can be improved; at the same time, the detachable design of the filter is convenient for regular cleaning or replacement, which reduces maintenance costs and improves the use efficiency and life of the device.

[0043] The present invention also provides a wind direction and air volume adjustment method applied to the above-mentioned wind direction and air volume adjustment device, and the wind direction and air volume adjustment method includes the following steps: S1, installing the air volume adjustment component 10 on the top plate of the tunnel and connecting it with the external wind tube in the tunnel to guide the airflow in the external wind tube to the first wind tube component 20 and the second wind tube component 30; adjusting the outlet of the first wind tube component 20 toward the excavation working face; S2, the central controller calculates the flow rate required by the tunnel according to the spatial size of the tunnel; S3, the central controller starts the fan in the external wind tube and controls the flow rate in the external wind tube to be greater than the calculated flow rate required by the tunnel; S4, the central controller controls at least one of the air volume adjustment component 10, the rotating component 40 and the air outlet adjustment component 50 according to the dust concentration data detected by the dust concentration sensor and the flow data detected by the first flow sensor and the second flow sensor.

[0044] By designing the wind direction and air volume adjustment method, the required flow rate can be calculated according to the size of the tunnel space, and the fan in the external air duct can be controlled to preventively control the air volume and ensure the ventilation effect. At the same time, the central controller automatically adjusts the wind direction and air volume according to real-time sensor data, reducing the need for manual monitoring and operation, and improving the degree of automation of the dust control system.

[0045] The method for adjusting wind direction and air volume also includes: installing multiple gas concentration sensors in the tunnel, and electrically connecting the multiple gas concentration sensors to the central controller respectively to detect the gas concentration in the tunnel; when the gas concentration detected by the gas concentration sensor is within a safe range, the central controller controls the state of the air volume adjustment component 10 to remain unchanged, and controls the rotating component 40 to drive the second wind tube component 30 to rotate continuously; when the gas concentration detected by the gas concentration sensor exceeds the safe range, the central controller controls the air volume adjustment component 10 to work, and increases the flow rate in the first wind tube component 20 and the second wind tube component 30 respectively to dilute the gas concentration in the tunnel.

[0046] Safety management is achieved by setting up gas concentration monitoring and control: combined with the monitoring of the gas concentration sensor, timely regulation of the gas concentration in the tunnel can be achieved to further ensure operation safety; at the same time, when the gas concentration is abnormal, the central controller automatically increases the flow rate in the air duct assembly for dilution, improving the ability to respond to emergencies and reducing the risk of accidents.

[0047] In a specific embodiment of the present invention, in step S4, the central controller uses the existing fuzzy logic algorithm to process the dust concentration data and flow data, and controls the air volume adjustment component 10, the rotating component 40 and the air outlet adjustment component 50 to work in coordination according to the existing PID control algorithm.

[0048] In summary, the present invention provides a wind direction and air volume regulating device and a wind direction and air volume regulating method. The present invention sets a central controller to respectively control the dust concentration sensor, the first flow sensor, the second flow sensor, the air volume regulating component 10, the first air duct component 20, the second air duct component 30, the rotating component 40 and the air outlet regulating component 50 to work together. Compared with the existing ventilation method of manually or mechanically adjusting the air outlet direction or the air guide plate, the present invention does not need manual control of the mechanical drive adjustment, so that the wind direction and air volume in the tunnel are convenient to adjust, saving time and labor, and can be flexibly responded to the changes in the space and dust concentration in the tunnel in time, avoiding large errors and lags in the adjustment of wind direction and air volume; and the present invention also ensures the adjustment accuracy and sensitivity of the wind direction and air volume, effectively realizing the air volume Precise control of wind direction and fast-response dynamic adjustment can achieve better ventilation and dust control effects; the present invention expands the ventilation range by arranging the first wind duct assembly 20 and the second wind duct assembly 30 to discharge air in multiple directions, so that the wind direction and air volume in the tunnel can adapt to the complex and changeable tunnel space, thereby ensuring the multi-directional supply of fresh air in the tunnel; by arranging the rotating assembly 40 to drive the second wind duct assembly 30 to rotate around the central axis of the second wind duct assembly 30, the airflow flowing out of the circulation port 31 can form a cyclone, which further facilitates the rapid diffusion of fresh air, increases the coverage range and angle of the airflow, and can meet the ventilation needs of closed spaces of different shapes; the present invention has a simple structure and low cost, is easy to assemble and subsequently maintain, and is suitable for large-scale promotion and use in various underground closed spaces such as mines.
