Description

Technical Field

[0001] This invention relates to the field of fog cannon technology, and in particular to an intelligent fog cannon and method for dust suppression in mines. Background Technology

[0002] Mining operations, including extraction, crushing, screening, and transportation, generate large amounts of dust, which not only severely pollutes the working environment and endangers miners' occupational health but also increases equipment wear and safety hazards. Currently, mist cannons (also known as wind-driven sprayers) have become one of the most widely used devices in the field of dust control in mines due to their advantages such as high dust suppression efficiency, wide coverage, and relatively high water resource utilization. Their basic principle is that a fan drives airflow through a duct and sprays water mist from the outlet, carrying the water mist generated by the atomizing nozzle to the target area. The water mist particles collide and agglomerate with the dust particles, achieving settling.

[0003] The patent application with publication number CN121429434 A discloses a multi-directional dust suppression device for open-cut tunnel construction, including a mobile platform. A rotating rod is rotatably connected to the inner wall of the mobile platform, and a gear is fixedly connected to the circumferential surface of the rotating rod. A rotating shaft is rotatably connected to the inner wall of the mobile platform, and a gear is fixedly connected to the circumferential surface of the rotating shaft. A rotating frame is fixedly connected to the circumferential surface of the rotating shaft, and a round rod is rotatably connected to the inner wall of the rotating frame. When it is necessary to adjust the spraying distance of the water mist, the elevation angle of the barrel can be adjusted so that the spraying distance of the water mist can be changed by the magnitude of the elevation angle.

[0004] The existing ones have the following defects: Firstly, the airflow direction adjustment is crude and difficult to accurately cover local dust points. Traditional fog cannons can only drive the entire air duct to swing in a large range by controlling the base, lacking the means to finely adjust the airflow direction. In actual mining operations, dust points are often localized, instantaneous, and changeable. The overall swing method is not only slow to respond, but also easily leads to a large amount of water mist being sprayed into dust-free areas, resulting in water waste (i.e., "overspraying"), while the target dust-producing area cannot receive sufficient concentration of water mist coverage (i.e., "missed spraying"), greatly reducing the dust suppression effect.

[0005] Secondly, the adjustment direction of the air outlet position is limited, and the adjustment precision is insufficient. Although some existing improvement solutions attempt to set up a guide mechanism inside the air duct for fine-tuning of the direction, most of them are mechanical unidirectional adjustment or step-by-step graded adjustment, which makes it difficult to achieve continuous, stepless displacement control in any direction. As a result, the flexibility and response speed of the air outlet position adjustment of the fog cannon still cannot meet the needs of precise dust suppression operations when facing complex and ever-changing mining conditions.

[0006] Third, there is a lack of effective linkage mechanism between the air outlet direction adjustment and the air guiding mechanism. In traditional solutions, the change of air outlet position and the deflection of the air outlet guide baffle are often executed by independent drive mechanisms, which can easily lead to asynchronous actions. This results in the airflow jet direction being inconsistent with the expected direction, and even airflow turbulence due to uncoordinated baffle deflection, further weakening the dust suppression effect.

[0007] Therefore, it is necessary to provide an intelligent fog cannon and method for dust suppression in mines to solve the above-mentioned technical problems. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent fog cannon and method for dust suppression in mines, so as to solve the defects of the prior art mentioned in the background.

[0009] Based on the above ideas, the present invention provides the following technical solution: A smart fog cannon for dust suppression in mines includes a control base and also includes: The air duct is installed on the top of the control base, with one end of the air duct set as the air inlet and the other end set as the air outlet. A fan is installed at the air inlet and an atomizing nozzle is installed at the air outlet. A connecting cylinder is coaxially disposed inside the air duct. Both ends of the air duct are fixedly connected to the inner walls of the air duct with partition rings. Elastic sealing cloths are fixedly connected between the two ends of the connecting cylinder and the two partition rings respectively. A fixed ring is fixedly installed on the inner wall of the air duct. A transverse movement mechanism is provided between the fixed ring and the connecting cylinder. The transverse movement mechanism drives the connecting cylinder to move radially to change the air outlet position. A support assembly is provided on the rear side of the elastic sealing cloth to support the elastic sealing cloth during the lateral movement of the connecting cylinder and prevent the elastic sealing cloth from folding. The air guide mechanism is located at the air inlet end of the air duct and is linked with the connecting cylinder. When the connecting cylinder moves laterally, the air guide mechanism is driven to deflect synchronously by a traction component to adjust the air outlet direction.

[0010] As a further aspect of the present invention: the transverse mechanism includes a plurality of second springs, which are arranged in a ring around the connecting cylinder, and the two ends of the second springs are respectively fixedly connected to the fixing ring and the connecting cylinder, for positioning the connecting cylinder at the center position of the air duct.

[0011] As a further aspect of the present invention: the transverse movement mechanism further includes multiple electromagnets, which are fixedly disposed on the inner wall of the fixed ring and evenly arranged along the circumference. A metal block corresponding to each of the multiple electromagnets is fixedly connected to the outside of the connecting cylinder. When the electromagnet is energized, it magnetically attracts the metal block. The magnetic force generated by the electromagnet after being energized drives the connecting cylinder to move radially relative to the air duct, thereby changing the air outlet position.

[0012] As a further aspect of the present invention: the support assembly includes multiple sets of retractable support members, which are evenly distributed along the circumference of the elastic sealing cloth. The two ends of the support members are respectively hinged to the connecting cylinder and the partition ring. Multiple elastic ropes are fixedly connected between the partition ring and the connecting cylinder. The multiple elastic ropes are distributed in a ring around the elastic sealing cloth. When the connecting cylinder moves laterally, the support members on the compression side automatically retract, and the support members on the tension side automatically extend. Each of the support members is always in contact with the surface of the elastic sealing cloth.

[0013] As a further embodiment of the present invention: the support member includes a fan-shaped plate and a storage plate, the fan-shaped plate is hinged to one end of the connecting cylinder, the storage plate is hinged to the partition ring, and the fan-shaped plate is slidably disposed inside the storage plate, and a first elastic spring is fixedly connected between the fan-shaped plate and the storage plate.

[0014] As a further embodiment of the present invention: the air guiding mechanism includes a plurality of second baffles, each of which is hinged to one end of the air duct, the plurality of second baffles are distributed in a ring around the center of the air duct, and a second sealing cloth is fixedly connected between the plurality of second baffles, a fixed cylinder is fixedly connected to the outside of the air duct, and a plurality of third springs are fixedly connected between the fixed cylinder and the plurality of second baffles.

[0015] As a further embodiment of the present invention: the traction component includes a connecting ring, which is sleeved on the outside of the connecting cylinder, and a hydraulic telescopic rod is fixedly connected to the outside of the connecting cylinder. The telescopic end of the hydraulic telescopic rod is fixedly connected to the connecting ring. A rotating rod corresponding to a plurality of second baffles is rotatably connected to the inside of the fixed cylinder. A first take-up reel is fixedly connected to the outside of the rotating rod. A first traction rope is fixedly wound around the outside of the first take-up reel. The first traction rope passes through the fixed cylinder and the air duct in sequence and is fixedly connected to the connecting ring. A plurality of second take-up reels are fixedly connected to the outside of the rotating rod. A second traction rope is fixedly wound around the outside of each of the plurality of second take-up reels. The second traction rope is fixedly connected to one end of a second baffle.

[0016] As a further embodiment of the present invention: a plurality of first baffles are hinged to one end of the connecting cylinder near the air inlet, and a first sealing cloth is fixedly connected between the plurality of first baffles. A sliding rod is fixedly connected to the outside of the plurality of first baffles, and a sliding block is slidably connected to the outside of the plurality of sliding rods. A movable ring is provided on the outside of the plurality of first baffles, and a plurality of push rods are fixedly connected to the outside of the movable ring. The push rods are hinged to the sliding blocks, and the connecting ring is fixedly connected to the movable ring.

[0017] A method for using an intelligent fog cannon for dust suppression in mines includes the following steps: Step 1: When localized dust suppression is required, adjust the angle of the air duct by controlling the base; Step 2: Based on the target air outlet deflection direction, drive the connecting cylinder to move radially relative to the air duct via the lateral movement mechanism located on the inner wall of the fixed ring. When the connecting cylinder moves laterally, the support mechanism on the back of the elastic sealing cloth supports the elastic sealing cloth. Step 3: When the connecting cylinder moves laterally, the displacement of the connecting cylinder is transmitted to the air guide mechanism located at the air outlet of the air duct through the traction component. The air guide mechanism deflects, so that the air outlet direction deflects with the lateral movement direction of the connecting cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By driving the connecting cylinder to move radially relative to the air duct through the transverse mechanism, and cooperating with the traction component to link the air guide mechanism to deflect synchronously, the air outlet direction can be continuously and finely adjusted in the secondary way. This allows the water mist sprayed from the atomizing nozzle to accurately cover local dust points, effectively avoiding the problems of "overspraying" water waste or "missing spraying" dust suppression failure caused by the traditional equipment's overall swing.

[0019] 2. An independent control loop is used to adjust the magnitude and direction of each group of currents, enabling the connecting cylinder to move laterally in any radial direction within a two-dimensional plane under controlled conditions. Compared to traditional mechanical unidirectional or step-by-step adjustment, this solution achieves stepless, continuous displacement control in any direction, significantly improving the flexibility and accuracy of air outlet position adjustment.

[0020] 3. Through the coordinated deflection of the second baffles on the tensioning and relaxation sides, the air outlet direction is adjusted in a coordinated manner, thereby accurately adapting to the offset of the air outlet position after the connecting cylinder moves laterally. The coordinated deflection directions of the two baffles ensure that the air outlet direction deflects synchronously with the lateral movement of the connecting cylinder, ensuring the consistency between the airflow jet direction and the offset direction of the connecting cylinder, and avoiding airflow turbulence or directional deviation caused by asynchronous adjustment.

[0021] 4. The connecting ring is moved by a hydraulic telescopic rod. The connecting ring simultaneously drives the first baffle adjustment mechanism at the air inlet and the traction mechanism at the air outlet, causing the air inlet diameter and the air outlet diameter to contract or expand synchronously. A single drive source can complete the coordinated adjustment of the two port diameters. The structure is compact and easy to control, avoiding the increased cost and synchronization problems caused by setting independent drive mechanisms for the air inlet and air outlet.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0027] like Figures 1 to 10 As shown, an intelligent fog cannon and method for dust suppression in mines include the following embodiments: Example 1: Includes a control base 1, which is assembled by multiple motors. This is existing technology and can be referenced from existing fog cannon bases. It also includes: Air duct 2 is installed on the top of control base 1, with one end of air duct 2 set as air inlet 201 and the other end set as air outlet 202. A fan 302 is installed at air inlet 201 and an atomizing nozzle 301 is installed at air outlet 202. The connecting cylinder 4 is coaxially arranged inside the air duct 2. Both ends of the air duct 2 are fixedly connected to the inner walls of the air duct 2 with partition rings 401. Both ends of the connecting cylinder 4 are fixedly connected to the two partition rings 401 with elastic sealing cloths 402 respectively. A fixed ring 6 is fixedly installed on the inner wall of the air duct 2. A transverse movement mechanism is provided between the fixed ring 6 and the connecting cylinder 4. The transverse movement mechanism drives the connecting cylinder 4 to move radially to change the air outlet position. A support assembly is provided on the rear side of the elastic sealing cloth 402 to support the elastic sealing cloth 402 when the connecting cylinder 4 moves laterally, and to prevent the elastic sealing cloth 402 from folding. The air guide mechanism is located at the air inlet 201 of the air duct 2 and is linked with the connecting tube 4. When the connecting tube 4 moves laterally, the air guide mechanism is driven to deflect synchronously by the traction component to adjust the air outlet direction.

[0028] In practice, when localized dust suppression is required, the water pump is first started to supply water to the atomizing nozzle 301. Simultaneously, the fan 302 is driven by a motor to operate, causing the water mist sprayed from the atomizing nozzle 301 to be blown outwards through the air outlet 202, thus achieving dust settling in the target area. Subsequently, the overall pitch or horizontal angle of the air duct 2 is adjusted by controlling the base 1 to determine the approximate spraying direction. Based on this, according to the precise deflection requirements of the target airflow direction, the connecting cylinder 4 is driven to move radially relative to the air duct 2 via a lateral movement mechanism located on the inner wall of the fixed ring 6. When the connecting cylinder 4 moves laterally, the support mechanism located behind the elastic sealing cloth 402 effectively supports the elastic sealing cloth 402, preventing it from folding, collapsing, or experiencing airflow turbulence during compression or stretching. At the same time, the traction component accurately transmits the lateral displacement of the connecting cylinder 4 to the air guide mechanism located at the air outlet of the air duct 2, causing the air guide mechanism to deflect synchronously, so that the air outlet direction is adjusted accordingly with the lateral movement of the connecting cylinder 4, thereby achieving precise fine-tuning of the atomized air outlet direction. By driving the connecting cylinder 4 to move radially relative to the air duct 2 through the lateral movement mechanism, and cooperating with the traction component to deflect synchronously with the air guide mechanism, the air outlet direction can be continuously and finely adjusted in a secondary manner, so that the water mist sprayed by the atomizing nozzle 301 can accurately cover the local dust points, effectively avoiding the problem of "overspraying" water waste or "missing spray" dust suppression failure caused by the traditional equipment that can only swing as a whole.

[0029] Furthermore, the directional fine-tuning of this solution only requires driving the relatively lightweight connecting cylinder 4 to perform radial displacement, and its motion inertia is much smaller than that of driving the entire ventilation duct 2 and control base 1 to rotate. Therefore, when a sudden dust storm or crosswind occurs at the mine working face, the system can complete the precise correction of the air outlet direction in a very short response time, greatly improving the equipment's dynamic adaptability to complex and changing working conditions.

[0030] In embodiment 2, the transverse mechanism includes multiple second springs 603, which are arranged in a ring around the connecting cylinder 4. The two ends of the second springs 603 are fixedly connected to the fixing ring 6 and the connecting cylinder 4 respectively, and are used to position the connecting cylinder 4 at the center of the air duct 2.

[0031] The transverse mechanism also includes multiple electromagnets 602, which are fixedly installed on the inner wall of the fixed ring 6 and evenly arranged in the circumferential direction. A metal block 601 corresponding to each of the multiple electromagnets 602 is fixedly connected to the outside of the connecting cylinder 4. When the electromagnet 602 is energized, it magnetically attracts the metal block 601. The magnetic force generated by the electromagnet 602 drives the connecting cylinder 4 to move radially relative to the air duct 2 to change the air outlet position.

[0032] In practical implementation, when fine-tuning of the air outlet position is required, multiple electromagnets 602 installed on the inner wall of the fixing ring 6 are energized. These electromagnets 602 are evenly distributed along the circumference of the connecting cylinder 4, divided into at least four groups, arranged in the upper, lower, left, and right directions respectively. Each group of electromagnets 602 has its current magnitude and direction adjusted via an independent control circuit. When a set current is applied to one or more electromagnets 602 at the corresponding position according to the desired lateral movement direction, the electromagnet 602 generates magnetic force and forms a magnetic attraction with the corresponding metal block 601, thereby applying a directional pulling force to the connecting cylinder 4. This pulls the connecting cylinder 4 laterally in any set radial direction within a two-dimensional plane, thus achieving precise adjustment of the air outlet position. The independent control circuit adjusts the magnitude and direction of the current in each group, allowing the connecting cylinder 4 to move laterally in any radial direction within a two-dimensional plane under control. Compared to traditional mechanical unidirectional or step-by-step adjustment, this scheme achieves stepless, continuous, arbitrary-direction displacement control, significantly improving the flexibility and accuracy of air outlet position adjustment.

[0033] Example 3: The support assembly includes multiple sets of retractable support members. The multiple sets of support members are evenly distributed along the circumference of the elastic sealing cloth 402. The two ends of the support members are respectively hinged to the connecting cylinder 4 and the partition ring 401. Multiple elastic ropes 504 are fixedly connected between the partition ring 401 and the connecting cylinder 4. The multiple elastic ropes 504 are distributed in a ring around the elastic sealing cloth 402. When the connecting cylinder 4 moves laterally, the support members on the compression side automatically retract, and the support members on the tension side automatically extend. Each support member is always in contact with the surface of the elastic sealing cloth 402.

[0034] The support includes a sector plate 501 and a storage plate 502. The sector plate 501 is hinged to one end of the connecting cylinder 4, and the storage plate 502 is hinged to the partition ring 401. The sector plate 501 is slidably disposed inside the storage plate 502, and a first elastic spring 503 is fixedly connected between the sector plate 501 and the storage plate 502.

[0035] In practice, when the airflow enters through the connecting cylinder 4 and exits through the channel enclosed by the elastic sealing cloth 402 towards the outlet 202, the airflow flows along the inner wall surface of the elastic sealing cloth 402. During this process, the support member set on the rear side of the elastic sealing cloth 402 provides continuous support to the elastic sealing cloth 402, allowing the elastic sealing cloth 402 to maintain its predetermined shape under the impact of the airflow. This avoids excessive deformation, denting, or bulging due to wind pressure, which would affect the stability of the flow channel cross-section. As a result, turbulence and eddies caused by abrupt changes in the flow channel are eliminated, ensuring that wind pressure loss is minimized and maintaining the effective range and jet speed of the outlet 202.

[0036] When the connecting cylinder 4 moves radially laterally relative to the air duct 2, the support member on one side of the lateral movement is compressed and automatically contracts, while the support member on the opposite side is stretched and automatically extends. Specifically, the fan-shaped plate 501 in each support member slides and extends relative to the receiving plate 502 to adapt to the shape change of the elastic sealing cloth 402 as the connecting cylinder 4 moves laterally. This allows the multiple support members to automatically adjust the annular support profile formed around the axis of the connecting cylinder 4, ensuring that the elastic sealing cloth 402 can obtain close support at each lateral movement position.

[0037] Furthermore, to ensure the rotational flexibility of the sector plate 501 and the storage plate 502 during the lateral movement of the connecting cylinder 4, and to prevent mechanical jamming or support failure due to excessive deflection, multiple elastic ropes 504 are fixedly connected between the partition ring 401 and the connecting cylinder 4. These elastic ropes 504 are distributed circumferentially along the elastic sealing cloth 402. The elastic constraint force of the elastic ropes 504 limits the deflection amplitude of the sector plate 501 and the storage plate 502, preventing excessive deflection. Simultaneously, the elastic ropes 504 provide auxiliary pull-back during the resetting of the connecting cylinder 4, ensuring that the support components remain within their effective working range.

[0038] Furthermore, multiple support components are distributed in a ring around the four circumferences of the connecting cylinder, forming an approximately circular flow channel cross-section inside the elastic sealing cloth 402. The spacing between each support component is uniform, which objectively plays a role in rectifying and equalizing the airflow. This makes the airflow velocity distribution in the area of ​​the elastic sealing cloth 402 more uniform, avoids the generation of flow deviation and vortex, and helps to improve the mixing uniformity of water mist and airflow at the atomizing nozzle 301, thereby improving the atomization effect and dust reduction efficiency.

[0039] Example 4: The air guiding mechanism includes multiple second baffles 801, each of which is hinged to one end of the air duct 2. The multiple second baffles 801 are distributed in a ring around the center of the air duct 2, and a second sealing cloth 802 is fixedly connected between the multiple second baffles 801. A fixed cylinder 8 is fixedly connected to the outside of the air duct 2, and multiple third springs 803 are fixedly connected between the fixed cylinder 8 and the multiple second baffles 801.

[0040] The traction component includes a connecting ring 707, which is sleeved on the outside of the connecting cylinder 4. A hydraulic telescopic rod 706 is fixedly connected to the outside of the connecting cylinder 4. The telescopic end of the hydraulic telescopic rod 706 is fixedly connected to the connecting ring 707. A rotating rod 901 corresponding to a plurality of second baffles 801 is rotatably connected to the inside of the fixed cylinder 8. A first take-up reel 902 is fixedly connected to the outside of the rotating rod 901. A first traction rope 905 is fixedly wound around the outside of the first take-up reel 902. The first traction rope 905 passes through the fixed cylinder 8 and the air duct 2 in sequence and is fixedly connected to the connecting ring 707. A plurality of second take-up reels 903 are fixedly connected to the outside of the rotating rod 901. A second traction rope 904 is fixedly wound around the outside of each of the plurality of second take-up reels 903. The second traction rope 904 is fixedly connected to one end of the second baffle 801.

[0041] In practice, when the connecting cylinder 4 moves radially laterally, the air outlet position changes accordingly. Simultaneously, the lateral movement of the connecting cylinder 4 drives multiple first traction ropes 905 to move synchronously via the connecting ring 707. Specifically, when one side of the first traction rope 905 is tightened, it causes the corresponding first take-up reel 902 to rotate. The first take-up reel 902 then drives the rotating rod 901, which is fixedly connected to it, to rotate synchronously. The rotating rod 901 then drives the second take-up reel 903, which is fixedly connected to it, to rotate. The second take-up reel 903 winds up the second traction rope 904, thereby pulling the corresponding second baffle 801 away from the center of the air duct 2. Meanwhile, for the other side of the first traction rope 905, which is in a relaxed state, the elastic restoring force of the third spring 803 pushes the corresponding second baffle 801 towards the center of the air duct 2. Through the coordinated deflection of the second baffle 801 on the tension side and the relaxation side, the air outlet direction is adjusted in a coordinated manner, thereby accurately adapting to the offset of the air outlet position after the connecting cylinder 4 moves laterally. The coordinated deflection directions of the two baffles ensure that the air outlet direction deflects synchronously with the lateral movement of the connecting cylinder 4, ensuring the consistency between the airflow jet direction and the offset direction of the connecting cylinder 4, and avoiding airflow turbulence or directional deviation caused by asynchronous adjustment.

[0042] Example 5: A plurality of first baffles 701 are hinged to one end of the connecting cylinder 4 near the air inlet 201. A first sealing cloth 702 is fixedly connected between the plurality of first baffles 701. A sliding rod 703 is fixedly connected to the outside of the plurality of first baffles 701. A sliding block is slidably connected to the outside of the plurality of sliding rods 703. A moving ring 704 is provided on the outside of the plurality of first baffles 701. A plurality of push rods 705 are fixedly connected to the outside of the moving ring 704. The push rods 705 are hinged to the sliding blocks. The connecting ring 707 is fixedly connected to the moving ring 704.

[0043] In practice, when concentrated wind-powered atomization dust suppression is needed for a distant target area, the hydraulic telescopic rod 706 is activated. The telescopic end of the hydraulic telescopic rod 706 pushes the connecting ring 707 towards the air inlet end 201. The connecting ring 707 drives the movable ring 704, which is fixedly connected to it, to move synchronously. The movable ring 704 then drives multiple push rods 705, which are fixedly connected to it, to move axially. Each push rod 705 drives the slider hinged to it to slide on the sliding rod 703 on the corresponding first baffle 701. Through the sliding cooperation between the slider and the sliding rod 703, multiple first baffles 701 are driven to deflect synchronously around the hinge point towards the center of the air duct 2. This causes the multiple first baffles 701 at the air inlet end 201 and the first sealing cloth 702 to retract together, forming a closed air inlet, effectively improving the concentration and wind speed of the incoming airflow.

[0044] At the same time, when the connecting ring 707 moves toward the air inlet end 201, the traction component, including the first traction rope 905 and the second traction rope 904, applies a relaxation effect to the multiple second baffles 801 at the air outlet end 202. Under the push of the elastic restoring force of the third spring 803, the multiple second baffles 801 simultaneously deflect and retract toward the center of the air duct 2, so that the air outlet diameter of the air outlet end 202 is reduced accordingly. Combined with the converging effect of the air inlet end 201, the concentration and spray speed of the air outlet airflow are further improved, and the long-distance delivery capability of the atomized water mist is enhanced.

[0045] When atomization dust suppression is required over a large area, the hydraulic telescopic rod 706 pushes the connecting ring 707 to move away from the air outlet 202. At this time, multiple first baffles 701 automatically unfold under the action of wind or in a state without driving constraints, causing the first sealing cloth 702 to unfold synchronously, thus expanding the air inlet diameter of the air inlet 201. Simultaneously, the connecting ring 707 drives multiple second baffles 801 to deflect outward and unfold via the traction component, causing the second sealing cloth 802 to unfold accordingly, and the air outlet diameter of the air outlet 202 to expand accordingly. Through the synchronous expansion of the diameters of the air inlet 201 and the air outlet 202, a wide-area coverage spray mode with large air volume and low wind speed is achieved to meet the dust suppression operation needs of large-area dusty areas.

[0046] The hydraulic telescopic rod 706 drives the connecting ring 707 to move. The connecting ring 707 simultaneously drives the adjustment mechanism of the first baffle 701 at the air inlet 201 and the linkage mechanism of the traction component at the air outlet 202, causing the air inlet diameter and the air outlet diameter to contract or expand synchronously. A single drive source can complete the coordinated adjustment of the two port diameters. The structure is compact and the control is simple, avoiding the increased cost and synchronization problems caused by setting up independent drive mechanisms for the air inlet and air outlet.

[0047] A method for using an intelligent fog cannon for dust suppression in mines includes the following steps: Step 1: When localized dust suppression is required, adjust the angle of the air duct 2 by controlling the base 1; Step 2: Based on the target air outlet deflection direction, drive the connecting cylinder 4 to move radially relative to the air duct 2 via the lateral movement mechanism set on the inner wall of the fixed ring 6. When the connecting cylinder 4 moves laterally, the support mechanism on the rear side of the elastic sealing cloth 402 supports the elastic sealing cloth 402. Step 3: When the connecting cylinder 4 moves laterally, the displacement of the connecting cylinder 4 is transmitted to the air guide mechanism located at the air outlet of the air duct 2 through the traction component.
