DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] The following is combined with Figures 1-9 The damper device according to the embodiment of the present invention is described in detail.

[0031] A damper device according to an embodiment of the present invention includes a door frame 1, a door panel 2, a baffle 5, and a drive assembly. The door panel 2 is hingedly connected to the inner circumference of the door frame 1 and is provided with a vent 3 extending through its thickness. The baffle 5 has one end rotatably connected to the door panel 2, allowing the other end of the baffle 5 to move toward and away from the door panel 2 to open and close the vent 3. The drive assembly includes a driver 17 and a transmission component. The driver 17 is disposed on the door panel 2, one end of the transmission component is connected to the driver 17, and the other end of the transmission component is connected to one end of the baffle 5 to drive the baffle 5 to rotate.

[0032] The damper device of the embodiment of the present invention is configured by arranging a vent 3 on the door panel 2 and arranging a baffle 5 at the vent 3, and utilizing a driving assembly to drive the baffle 5 to rotate relative to the door panel 2, so that the other end of the baffle 5 moves in a direction away from the door panel 2 or in a direction close to the door panel 2. When the other end of the baffle 5 moves in a direction away from the door panel 2, the ventilation area of ​​the vent 3 increases until the baffle 5 is parallel to the thickness direction of the door panel 2, and the ventilation area of ​​the vent 3 is maximized. When the other end of the baffle 5 moves in a direction close to the door panel 2, the ventilation area of ​​the vent 3 decreases until the baffle 5 is perpendicular to the thickness direction of the door panel 2, and the vent 3 is completely closed, thereby realizing the adjustment of the ventilation area of ​​the vent 3. In addition, the baffle 5 has good pressure resistance and is not easy to deform, and can well adapt to the movement under wind pressure, thereby improving the adjustment accuracy and service life of the damper device.

[0033] Secondly, when the ventilation area of ​​the vent 3 is the largest, the baffle 5 fully opens the vent 3, ensuring a larger effective ventilation area, increasing the adjustment range of the air volume by the damper device, and improving the ventilation efficiency and ventilation effect.

[0034] Specifically, if Figure 1-Figure 3 As shown, a door panel 2 is hingedly connected to the inner sidewall of the door frame 1 at one end in the width direction. Two door panels 2 are provided, and the two door panels 2 are arranged opposite each other in the width direction of the door panel 2. Each door panel 2 is provided with a plurality of vents 3 spaced apart in the vertical direction. Each vent 3 is provided with a baffle 5, which is opened and closed by rotating the baffle 5 relative to the door panel 2.

[0035] The upper end of the baffle 5 is rotatably connected to the door panel 2. The baffle 5 rotates relative to the door panel 2 so that the lower end of the baffle 5 can move closer to and farther from the door panel 2 to open and close the vent 3. Because the baffle 5 is installed within the vent 3, the driver 17 cannot directly drive the baffle 5 to rotate. Instead, the driver 17 drives the transmission component to move, and the transmission component is connected to the baffle 5 to drive the baffle 5 to rotate. This facilitates the installation of the driver 17 and the transmission component while improving the movement reliability of the baffle 5.

[0036] In some embodiments, as Figure 1-Figure 5 As shown, the damper device also includes a mounting frame 4 and a mounting box 6. The mounting frame 4 is mounted within the vent 3. The baffle 5 is rotatably mounted on the mounting frame 4. The mounting box 6 is mounted within the mounting frame 4. The transmission component is mounted within the mounting box 6. The driver 17 is mounted on the outer wall of the mounting box 6. One end of the driver 17 extends into the mounting box 6 and is connected to the transmission component. By mounting the mounting frame 4 within the vent 3, the baffle 5 is mounted within the mounting frame 4, and the mounting frame 4 is connected to the door panel 2, the baffle 5 is connected to the door panel 2. The provision of the mounting box 6 facilitates the installation of the driver 17 and the transmission component.

[0037] Optionally, the door panel 2 has a first side surface and a second side surface in the thickness direction thereof, the first side surface being the windward side, and the second side surface of the door panel 2 is provided with an installation groove, which is arranged around the vent 3 and connected to the vent 3, and the installation frame 4 is inserted into the installation groove.

[0038] Mounting frame 4 is provided with mounting plates 24 on both outer walls in the width direction of door panel 2. A connecting groove corresponding to mounting plate 24 is provided on the second side surface of door panel 2. The connecting groove is connected to the mounting groove, and mounting plate 24 fits within the connecting groove. Mounting plate 24 has a first connecting hole, and the wall surface of the connecting groove has a second connecting hole opposite and connected to the first connecting hole. A connecting member passes through the first connecting hole and connects to the second connecting hole, thereby connecting mounting plate 24 to door panel 2, and thus connecting mounting frame 4 to door panel 2.

[0039] Optionally, the two mounting plates 24 are symmetrically arranged, and there are multiple first connection holes, and correspondingly, there are multiple second connection holes, and the multiple second connection holes are connected to the multiple first connection holes in a one-to-one correspondence. For example, the second connection holes are threaded holes, and the connecting members are bolts.

[0040] The mounting frame 4 of this embodiment is detachably connected to the door panel 2, facilitating maintenance and replacement of the mounting frame 4. The mounting plate 24 of the mounting frame 4 is connected to the second side surface of the door panel 2. The mounting plate 24 fits within the connecting groove and is secured via a plurality of connecting members. The connecting groove is provided with a second connecting hole. The connecting member and the second connecting hole cooperate to achieve a tight connection, allowing the mounting frame 4 to be easily removed from and installed on the vent 3. This greatly facilitates routine maintenance, troubleshooting, and replacement of the drive assembly of the mounting frame 4, effectively reducing downtime and improving the operating efficiency of the damper device.

[0041] In some embodiments, the transmission component includes a rotating rod 7, a first gear 8 and a tooth plate 9. One end of the rotating rod 7 is connected to one end of the baffle 5, and the other end of the rotating rod 7 is rotatably inserted into the mounting box 6. The first gear 8 is fitted on the outer periphery of the other end of the rotating rod 7. The tooth plate 9 is disposed in the mounting box 6 and meshes with the first gear 8. The driver 17 is connected to the tooth plate 9 to drive the gear to move in the up and down directions.

[0042] Specifically, if Figure 6-Figure 7 As shown, a rotating rod 7 is provided for rotation inside the installation box 6. The end portion of the rotating rod 7 close to the side of the baffle 5 passes through the installation box 6 and is fixedly connected to the outer wall of the baffle 5. The outer wall of the rotating rod 7 is fixedly sleeved with a first gear 8 and the first gear 8 is located in the installation box 6. The first gear 8 is engaged with the tooth plate 9. The driver 17 is connected to the tooth plate 9. The up and down movement of the tooth plate 9 drives the first gear 8 to rotate around the width direction of the door panel 2. The first gear 8 rotates around the width direction of the door panel 2 to drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 drives the baffle 5 to rotate.

[0043] When the ventilation area of ​​the vent 3 needs to be adjusted, the tooth plate 9 is driven up and down by the driver 17 to open or close the vent 3. The coordinated work among the driver 17, the tooth plate 9, the first gear 8, the rotating rod 7 and the baffle 5 not only improves the air volume adjustment accuracy of the damper device, but also due to the fixed connection between the baffle 5 and the rotating rod 7, enhances the strength and pressure resistance of the entire damper device, effectively prevents the damper device from deformation under high pressure environment, and improves the stability and service life of the damper device.

[0044] It should be noted that when the tooth plate 9 is at the lower end, the baffle 5 is vertically downward, so that the vent 3 is in a closed state. When the tooth plate 9 is at the upper end, the baffle 5 is in a horizontal state, so that the vent 3 is fully open. By moving the tooth plate 9 up and down, the rotation state of the baffle 5 is adjusted, thereby adjusting the opening of the vent 3.

[0045] In some embodiments, the transmission component also includes a movable block 10 and a guide rod 11. The movable block 10 is connected to the side of the tooth plate 9 away from the first gear 8. The guide rod 11 extends in the up and down directions and the upper and lower ends of the guide rod 11 are connected to the inner wall surface of the mounting box 6. The movable block 10 slides on the guide rod 11, and the driver 17 is connected to the movable block 10.

[0046] Specifically, if Figure 6-Figure 7 As shown, the upper end of the guide rod 11 is connected to the inner wall surface of the upper end of the installation box 6, and the lower end of the guide rod 11 is connected to the inner wall surface of the lower end of the installation box 6. The movable block 10 is sleeved on the guide rod 11, and the guide rod 11 guides the movement direction of the movable block 10. The movable block 10 is connected to the tooth plate 9 to guide the movement direction of the tooth plate 9. The movable block 10 is driven by the driver 17 to move in the up and down direction, driving the tooth plate 9 to move up and down, thereby realizing the rotation of the baffle 5.

[0047] Optionally, there are multiple guide rods 11 , and the multiple guide rods 11 are arranged at intervals in the width direction of the door panel 2 .

[0048] In some embodiments, the transmission component also includes a screw and a connecting plate 13. The screw is rotatably arranged in the mounting box 6 and is arranged parallel to the guide rod 11. The connecting plate 13 is arranged on the screw and moves along the screw when the screw rotates in the up and down directions. The connecting plate 13 is connected to the movable block 10, and the driver 17 is connected to the screw.

[0049] Specifically, if Figure 6-Figure 7As shown, the screw rod extends in the up-down direction, the upper end of the screw rod is rotatably connected to the inner wall surface of the upper end of the mounting box 6, and the lower end of the screw rod is rotatably connected to the inner wall surface of the lower end of the mounting box 6. The connecting plate 13 is threadedly connected to the screw rod. When the screw rod is driven to rotate in the up-down direction by the driver 17, the connecting plate 13 can move in the up-down direction. By connecting the connecting plate 13 with the movable block 10, the up-down movement of the movable block 10 is realized, thereby realizing the rotation of the baffle 5.

[0050] Optionally, a first limit block and a second limit block are provided on the screw rod, and the first limit block and the second limit block are arranged at intervals in the up and down directions and the first limit block is located above the second limit block, and the connecting plate 13 is provided between the first limit block and the second limit block. When the screw rod rotates, the first limit block and the second limit block rotate synchronously with the screw rod, and the first limit block and the second limit block are used to limit the movement range of the connecting plate 13 in the up and down directions.

[0051] In some embodiments, the transmission component further includes a worm wheel 14 and a worm 15 . The worm wheel 14 is disposed at the end of the screw, and the worm 15 is rotatably disposed in the mounting box 6 . The worm wheel 14 is engaged with the worm 15 , and the driver 17 is connected to the worm 15 .

[0052] Specifically, if Figure 6-Figure 7 As shown, the worm wheel 14 is fixedly sleeved on the screw and located above the first limit block. The worm 15 is engaged with the worm wheel 14, and the driver 17 drives the worm 15 to rotate and drive the worm wheel 14 to rotate, thereby realizing the rotation of the screw and further realizing the rotation of the baffle 5.

[0053] In some embodiments, the damper device also includes a connecting frame 16, there are two mounting boxes 6, the two mounting boxes 6 are symmetrically arranged, one end of the connecting frame 16 is connected to one of the mounting boxes 6, and the other end of the connecting frame 16 is connected to the other mounting box 6, and the driver 17 is provided on at least one of the two mounting boxes 6. The transmission component also includes an output rod 18, which is rotatably provided through the mounting box 6 and the connecting frame 16 and is connected to the driver 17.

[0054] Specifically, if Figure 1-Figure 7 As shown, both ends of the connecting frame 16 pass through and are fixedly arranged on the corresponding two mounting boxes 6, and an output rod 18 is rotatably arranged between the two mounting boxes 6. The output rod 18 is arranged in the connecting frame 16, and one end of the output rod 18 extends into one of the mounting boxes 6, and the other end of the output rod 18 passes through the other mounting box 6 and extends outward to be connected to the driver 17. Through the output rod 18, one driver 17 drives the two ends of the baffle 5 to rotate synchronously, thereby improving the rotation stability.

[0055] For example, the driver 17 is a motor.

[0056] In some embodiments, the transmission component further includes a second gear 19 and a third gear 20 . The second gear 19 is sleeved on the outer periphery of the output rod 18 , and the third gear 20 is fitted on the outer periphery of the worm 15 . The third gear 20 meshes with the second gear 19 .

[0057] Specifically, if Figure 6-Figure 7 As shown, the output rod 18 is arranged inside the connecting frame 16, and two second gears 19 are fixedly sleeved on the outer side walls at both ends of the output rod 18. The ends of the two worm gears 15 in the two mounting boxes 6 are fixedly provided with third gears 20, and the two second gears 19 are respectively engaged with the corresponding two third gears 20, so that the driver 17 drives the output rod 18 to rotate and drive the second gear 19 to rotate, and the second gear 19 drives the third gear 20 to rotate to drive the worm gear 15 to rotate, thereby realizing the rotation of the baffle 5.

[0058] Optionally, the second gear 19 and the third gear 20 are both bevel gears.

[0059] In this embodiment, the output rod 18 is driven to rotate by the driver 17, and the output rod 18 drives the worm 15 to rotate through the engagement of the second gear 19 and the third gear 20. The worm 15 engages with the worm wheel 14 to drive the screw 12 to rotate. The rotation of the screw 12 causes the connecting plate 13 to drive the movable block 10 to move up and down along the guide rod 11. The movement of the movable block 10 causes the tooth plate 9 to move up and down, and through the cooperation of the tooth plate 9 and the first gear 8, the rotating rod 7 is driven to rotate, and then the baffle 5 is rotated around the rotating rod 7 to adjust the opening of the vent 3.

[0060] In this embodiment, the baffle 5, the rotating rod 7, the first gear 8 and the tooth plate 9 are used in conjunction with each other, and the vent 3 is opened and closed by adjusting the rotation of the baffle 5, which facilitates the adjustment of the ventilation volume. The setting and use of the baffle 5 and the rotating rod 7 improve the strength and pressure resistance of the damper device, avoid deformation of the damper device during use, and ensure the stability of the adjustment function and a long service life.

[0061] In some embodiments, a sealing frame 21 is provided on the inner circumference of the mounting frame 4, a first sealing member 22 is provided on the sealing frame 21, and a second sealing member 23 is provided on the side of the baffle 5 facing the sealing frame 21. When the baffle 5 closes the vent 3, the first sealing member 22 and the second sealing member 23 are sealed together.

[0062] Specifically, if Figure 4-Figure 5 As shown, the sealing frame 21 is fixedly arranged inside the mounting frame 4, and a first sealing member 22 is fixedly arranged on the outer wall of the sealing frame 21 close to the baffle 5, and a second sealing member 23 is fixedly arranged on the outer wall of the baffle 5 close to the sealing frame 21, and both the first sealing strip and the second sealing strip are arranged in a "mouth" shape.

[0063] Optionally, the side length of the second sealing member 23 is smaller than the side length of the first sealing member 22 .

[0064] In this embodiment, the sealing frame 21 is fixedly installed in the installation frame 4, and a first seal 22 is provided on the side of the sealing frame 21 facing the baffle 5, and the contact surface of the baffle 5 is provided with a second seal 23. When the baffle 5 closes the vent 3, the first seal 22 and the second seal 23 form a double sealing defense line between the sealing frame 21 and the baffle 5. Moreover, the first seal 22 and the second seal 23 are both "mouth"-shaped, and the side length of the second seal 23 is slightly smaller than the first seal 22, so that when the baffle 5 closes the vent 3, the second seal 23 can be completely embedded in the interior of the first seal 22, thereby enhancing the sealing effect, effectively preventing air leakage, and ensuring the efficiency and reliability of the ventilation system when sealing is required.

[0065] In some embodiments, the damper device also includes a monitoring component and a control box 29. The monitoring component is suitable for being installed in a mine tunnel. The monitoring component includes a sensor module 27 and a wireless communication module 28. The sensor module 27 is connected to the wireless communication module 28. The control box 29 is installed in the door frame 1. A data analysis module 30 and a controller 31 are provided in the control box 29. The data analysis module 30 is respectively connected to the communication module and the controller 31. The controller 31 is connected to the driver 17.

[0066] Specifically, if Figure 1 、 Figure 8 and Figure 9 As shown, the damper device also includes a top plate 25, a mounting bracket 26 is fixedly provided at the bottom of the top plate 25, a sensor module 27 and a wireless communication module 28 are installed at the bottom of the mounting bracket 26, a control box 29 is fixedly provided on the outer wall of the door frame 1, and a data analysis module 30 and a controller 31 are fixedly provided inside the control box 29.

[0067] Optionally, the controller 31 is a PLC controller 31 .

[0068] In this embodiment, the mounting rack 26 is arranged on the top plate 25, and the sensor module 27 and the wireless communication module 28 are integrated at the lower part of the mounting rack 26. The sensor module 27 and the wireless communication module 28 are connected by a data line (not shown in the figure). The sensor module 27 includes gas concentration, wind speed, and wind pressure sensor devices. The sensor module 27 can monitor the air environment in the mine tunnel in real time, including key parameters such as gas concentration, wind speed, and wind pressure. These monitoring data are transmitted to the data analysis module 30 in the control box 29 arranged on the door frame 1 through the wireless communication module 28 for processing. The data analysis module 30 compares and analyzes the air monitoring data in the mine tunnel monitored by the sensor module 27 with the preset air quality data in the data analysis module 30. The processed data and control instructions are then sent to the PCL controller 31. The data analysis module 30 and the PCL controller 31 are connected by a wired connection (RS-485, Ethernet) or a wireless connection (Wi-Fi, 4G / 5G) for data transmission. The PCL controller 31 adjusts the baffle 5 through the motor, realizing automatic control of the air door device. This intelligent control system not only improves the convenience and response speed of operation, but also greatly enhances the accuracy and safety of mine tunnel ventilation management, creating a safer working environment for miners.

[0069] In this embodiment, the sealing frame 21, the first sealing member 22, and the second sealing member 23 are arranged to improve the sealing performance of the ventilation opening 3. In combination with the arrangement of the control monitoring assembly and the controller 31, the air door device can adjust the air volume according to the air environment in the coal mine tunnel, improving the convenience.

[0070] The air door adjusting method of the embodiment includes receiving air monitoring data in the mine tunnel and comparing the monitoring data with preset data to issue an adjusting instruction. When the adjusting instruction is to increase the ventilation area of the ventilation opening, the controller controls the motor to rotate forward to move the other end of the baffle in a direction away from the door plate to increase the ventilation area of the ventilation opening, and adjusts the opening degree of the baffle by controlling the forward rotation time of the motor. When the adjusting instruction is to reduce the ventilation area of the ventilation opening, the controller controls the motor to reverse to move the other end of the baffle in a direction close to the door plate to reduce the ventilation area of the ventilation opening, and adjusts the opening degree of the baffle by controlling the reverse rotation time of the motor.
