[0031] 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.

[0032] like Figure 1-Figure 6 As shown, the mine wind window of the embodiment of the present invention comprises a mounting frame 1 , a pivot frame 2 , fan blades 3 and a driving device 4 .

[0033] The mounting frame 1 is provided with a personnel passage 11. The pivot frame 2 is pivotally connected to the mounting frame 1 and can rotate between a closed position for closing the personnel passage 11 and an open position for opening the personnel passage 11, and the pivot frame 2 is provided with a ventilation passage. A plurality of blades 3 are arranged side by side in the ventilation passage, and the blades 3 are pivotally connected to the pivot frame 2. The driving device 4 is provided on the pivot frame 2 and connected to the blades 3 to drive the blades 3 to pivot relative to the pivot frame 2.

[0034] like Figure 1-Figure 3 As shown, the installation frame 1 is used to be vertically arranged in the lane. Preferably, the installation frame 1 is assembled by a plurality of modules, and the size and weight of any module are set to be movable and assembled by a single person. The installation frame 1 is provided with a personnel passage 11 running through it in the front-to-back direction for personnel to pass through.

[0035] The pivot frame 2 is pivotally connected to the mounting frame 1 via a pivot, and can rotate between a closed position for closing the personnel passage 11 and an open position for opening the personnel passage 11. The pivot can be arranged in the left-right direction or in the up-down direction. Preferably, the pivot extends in the left-right direction and is arranged at one end of the pivot frame 2 in the up-down direction. In the closed position, the pivot frame 2 is embedded in the personnel passage 11 or overlapped with the mounting frame 1. In the open position, the extension direction of the pivot frame 2 intersects with the extension direction of the mounting frame 1 and forms an angle.

[0036] The pivot frame 2 is provided with a ventilation passage running through it in the front-to-back direction, and in the closed position, the ventilation passage overlaps with the personnel passage 11. A plurality of fan blades 3 extend transversely and are arranged side by side in the longitudinal direction in the ventilation passage, and both transverse ends of the fan blades 3 are pivotally connected to the pivot frame 2, so that the air volume passing through the ventilation passage can be adjusted by rotating the fan blades 3.

[0037] The driving device 4 is disposed on the pivot frame 2 and connected to the fan blades 3 to drive the fan blades 3 to pivot in the left-right direction relative to the pivot frame 2, thereby adjusting the air volume passing through the ventilation passage.

[0038] Preferably, the mounting frame 1 or the pivoting frame 2 is provided with a sealing frame, which is connected between the mounting frame 1 and the pivoting frame 2 in the closed position and surrounds the outer periphery of the personnel passage 11. More preferably, the sealing frame is provided on the inner peripheral wall surface of the personnel passage 11.

[0039] The mining wind window of the embodiment of the present invention is provided with a pivot frame and a mounting frame that can be pivotally connected to close and open the personnel passage of the mounting frame, and a fan blade is provided in the ventilation passage of the pivot frame. During normal use, the pivot frame closes the personnel passage and controls the passing air volume through the fan blade. When personnel evacuation is required, the pivot frame opens the personnel passage to allow personnel to pass through. It can ensure the area of ​​the ventilation passage, thereby ensuring the air volume, and can ensure that personnel can pass smoothly, while also having strong structural stability and durability.

[0040] In some embodiments, the mining wind window of the embodiment of the present invention also includes a locking device 5, which is provided on one of the mounting frame 1 and the pivot frame 2, and can move between a locking position and a release position relative to one of the mounting frame 1 and the pivot frame 2. In the locking position, the locking device 5 can be connected to the other of the mounting frame 1 and the pivot frame 2 to make the pivot frame 2 in a closed position. In the release position, the locking device 5 is separated from the other of the mounting frame 1 and the pivot frame 2, and the pivot frame 2 can rotate between a closed position and an open position.

[0041] like Figure 1 and Figure 2 As shown, the mounting frame 1 is provided with a locking device 5, which can move between a locking position and a releasing position relative to the mounting frame 1. When the pivot frame 2 is in the closed position and the locking device 5 is in the locking position, the locking device 5 is connected to the pivot frame 2 to lock the pivot frame 2 in the closed position. When the locking device 5 is in the releasing position, the locking device 5 is separated from the pivot frame 2, and the pivot frame 2 can rotate between the closed position and the open position.

[0042] It is understandable that when the pivot frame 2 is in the open position, the locking device 5 can also be in the locked position, but the pivot frame 2 cannot be locked.

[0043] It is understandable that the locking device may also be provided on the pivot frame.

[0044] In some embodiments, the locking device 5 includes a first limit member 51, which is pivotally connected to the mounting frame 1. In the locked position, the first limit member 51 can stop the pivot frame 2 in the closed position and is located on the side of the direction in which the pivot frame 2 rotates toward the open position. In the released position, the first limit member 51 is spaced apart from the pivot frame 2 in rotation space.

[0045] like Figure 1 and Figure 2 As shown, the first stopper 51 is pivotally connected to the mounting frame 1 in the front-rear direction and is disposed on the rear end surface of the mounting frame 1. Figure 1 As shown, when the pivot frame 2 is in the closed position and the locking device 5 is in the locked position, part of the first stopper 51 rotates to the side of the direction in which the pivot frame 2 rotates from the closed position to the open position and abuts against the pivot frame 2. In other words, part of the first stopper 51 rotates to the rear side of the pivot frame 2 and abuts against the rear end surface of the pivot frame 2, thereby stopping the pivot frame 2 and locking the pivot frame 2 in the closed position. Figure 2 As shown, when the locking device 5 is in the release position, the first limiting member 51 is spaced apart from the rotation space of the pivot frame 2 , in other words, the first limiting member 51 is spaced apart from the personnel passage 11 .

[0046] It is understandable that the structure of the locking device is not limited to including the first limiting member. In other embodiments, the locking device is a latch, a lock, etc.

[0047] In some embodiments, the locking device 5 also includes a locking shaft 52 and a second limit member 53. The locking shaft 52 is passed through the mounting frame 1 and can rotate around the axial direction of the locking shaft 52 relative to the mounting frame 1. One end of the locking shaft 52 is provided with a second limit member 53, and the other end of the locking shaft 52 is provided with a first limit member 51. In the locked position, the second limit member 53 and the first limit member 51 can clamp the pivot frame 2 in the closed position. In the released position, the second limit member 53 and the first limit member 51 are both separated from the rotation space of the pivot frame 2.

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, the locking shaft 52 extends in the front-to-back direction and is passed through the mounting frame 1, and the locking shaft 52 can rotate around the axial direction of the locking shaft 52 relative to the mounting frame 1, and the front and rear ends of the locking shaft 52 both protrude from the mounting frame 1, and the rear end of the locking shaft 52 is provided with a first limiting member 51, and the front end of the locking shaft 52 is provided with a second limiting member 53, and the first limiting member 51 and the second limiting member 53 are arranged at intervals in the front-to-back direction.

[0049] When the pivot frame 2 is in the closed position and the locking device 5 is in the locked position, the edge of the pivot frame 2 is clamped between the first limit member 51 and the second limit member 53. The first limit member 51 stops the pivot frame 2 from rotating from the closed position to the open position, and the second limit member 53 stops the pivot frame 2 from rotating in the opposite direction from the closed position to the open position, so as to ensure that the pivot frame 2 is locked in the closed position and prevent the pivot connection between the pivot frame 2 and the mounting frame 1 from being damaged by reverse rotation.

[0050] When the locking device 5 is in the release position, the second limiting member 53 and the first limiting member 51 are both spaced apart from the rotation space of the pivot frame 2 . In other words, the second limiting member 53 and the first limiting member 51 are both spaced apart from the personnel passage 11 .

[0051] In some embodiments, the locking device 5 further includes a gripping portion 54 , and the gripping portion 54 , the first limiting member 51 , and the second limiting member 53 are sequentially arranged on the locking shaft 52 along the axial direction of the locking shaft 52 .

[0052] like Figure 5 As shown, a gripping portion 54 is further provided at the rear end of the locking shaft 52. The gripping portion 54 is located on the side of the first limiting member 51 away from the second limiting member 53. The gripping portion 54 is used for an operator to hold to rotate the locking device 5 between the open position and the locked position.

[0053] It is understandable that the locking device is not limited to including a grip portion. In other embodiments, the locking device rotates under the drive of the driving member, and the mounting frame is provided with a switch for controlling the start and stop of the driving member.

[0054] In some embodiments, the mining wind window of the embodiment of the present invention further includes a connecting rod device 6, which is connected to the multiple blades 3, and the connecting rod device 6 or one of the blades 3 is connected to the driving device 4 to enable the multiple blades 3 to rotate synchronously.

[0055] like Figure 3 and Figure 4 As shown, the plurality of blades 3 are arranged in sequence along the up-down direction, and the connecting rod device 6 is arranged along the up-down direction and connected to the same end of the plurality of blades 3 along the left-right direction. The driving device 4 can be connected to the connecting rod device 6, so that the plurality of blades 3 are driven to rotate synchronously through the connecting rod device 6 to adjust the air volume. The driving device 4 can also be connected to one end of one of the blades 3, directly driving the blade 3 to rotate, and driving the other blades 3 to rotate synchronously through the connecting rod device 6 to adjust the air volume.

[0056] It is understandable that the mining wind window is not limited to including a connecting rod device. In other embodiments, the fan blades are connected to the driving device one by one, or a pulley is provided at the end of the fan blade, and the driving device is also provided with a pulley, and the pulleys of multiple fan blades are connected to the pulley of the driving device through a transmission belt.

[0057] In some embodiments, the connecting rod device 6 includes a first rod body 61 and a second rod body 62, the first rod body 61 extends along the side-by-side arrangement direction of the multiple fan blades 3, the first rod body 61 is provided with a plurality of second rod bodies 62 arranged at intervals along its extension direction, and the second rod body 62 is pivotally connected to the first rod body 61, the plurality of second rod bodies 62 are connected one-to-one with the plurality of fan blades 3, and the second rod body 62 extends along the radial direction of the corresponding fan blades 3.

[0058] like Figure 4 As shown, a second rod body 62 is provided at the same end of multiple fan blades 3 in the left-right direction. The second rod body 62 extends radially along the connected fan blades 3 and is coaxially arranged with the connected fan blades 3. The first rod body 61 extends in the up-down direction. The multiple second rod bodies 62 are all pivotally connected to the first rod body 61 around the left-right direction and are arranged at intervals in the up-down direction.

[0059] One of the fan blades 3 is connected to the driving device 4 so as to rotate under the drive of the driving device 4 and drive the connected second rod body 62 to rotate synchronously. The second rod body 62 drives the remaining fan blades 3 to rotate synchronously with the fan blade 3 through the first rod body 61 and other second rod bodies 62, thereby adjusting the wind volume.

[0060] In some embodiments, Figure 1-Figure 4 As shown, in order to ensure the structural strength of the mounting frame 1 and the pivot frame 2, the mounting frame 1 is provided with two personnel passages 11, and the two personnel passages 11 are arranged at intervals along the left-right direction, and the pivot frame 2 is provided with two ventilation passages, and the two ventilation passages are arranged at intervals along the left-right direction, and are arranged one-to-one with the two personnel passages 11, and each ventilation passage is provided with a plurality of fan blades 3, and the plurality of fan blades 3 of each ventilation passage are connected to the corresponding first rod body 61.

[0061] Specifically, the right ends of the plurality of blades 3 of the left ventilation channel are each provided with a second rod 62, and are connected to a first rod 61 through the second rod 62. The left ends of the plurality of blades 3 of the right ventilation channel are provided with a second rod 62, and are connected to another first rod 61 through the second rod 62. The two first rods 61 are both located between the two ventilation channels and are arranged opposite to each other in the left-right direction. One of the blades 3 of the left ventilation channel is connected to the driving device 4.

[0062] The connecting rod device 6 also includes a third rod (not shown in the figure), which is connected between the two first rods 61 to make the two first rods 61 move synchronously, thereby making the blades 3 of the two ventilation channels rotate synchronously. Preferably, the third rod is a straight rod extending in the left-right direction.

[0063] In some embodiments, the driving device 4 is a telescopic cylinder, and the mining wind window further includes a transmission device 7 , which is connected between the telescopic cylinder and one of the fan blades 3 .

[0064] like Figure 3 As shown, the driving device 4 is a telescopic cylinder, preferably a telescopic air cylinder that can be extended in the up and down directions. The telescopic air cylinder is connected to one of the fan blades 3 of the left ventilation channel through the transmission device 7 to drive the fan blade 3 to rotate through the transmission device 7.

[0065] In some embodiments, the transmission device 7 includes a belt drive mechanism 71 and a right-angle commutator 72, one pulley of the belt drive mechanism 71 is arranged on the pivot frame 2, the other pulley of the belt drive mechanism 71 is arranged on the input shaft of the right-angle commutator 72, the output shaft of the right-angle commutator 72 is connected to one of the fan blades 3, and the transmission belt of the belt drive mechanism 71 is connected to the telescopic cylinder.

[0066] like Figure 3 As shown, the transmission device 7 includes a belt transmission mechanism 71 and a right-angle commutator 72. The belt transmission mechanism 71 includes two pulleys and a transmission belt wrapped around the two pulleys. One of the pulleys is rotatable in the front-rear direction and is arranged on the top of the pivot frame 2. The other pulley is arranged on the input shaft of the right-angle commutator 72. The output shaft of the right-angle commutator 72 is connected to one of the fan blades 3 of the left ventilation channel. The telescopic cylinder is connected to the transmission belt through a bracket.

[0067] The telescopic cylinder drives the connected part of the transmission belt to move in the up-down direction, thereby driving the input shaft of the right-angle commutator 72 to rotate through another pulley, so that the output shaft of the right-angle commutator 72 drives the connected fan blade 3 to rotate.

[0068] In some embodiments, the mine wind window of the embodiment of the present invention further includes a rotary encoder 8 , a proximity switch sensor 9 and a trigger switch 10 .

[0069] The rotary encoder 8 is disposed on the pivot frame 2 and connected to the other fan blade 3. At least two proximity switch sensors 9 are provided, wherein one second rod body 62 is located between two adjacent proximity switch sensors 9. At least two trigger switches 10 are provided, wherein one trigger switch 10 is disposed at the forward rotation limit position of the other second rod body 62, and the other trigger switch 10 is disposed at the reverse rotation limit position of the other second rod body 62, and the trigger switch 10 is used to turn off the drive device 4 when it abuts against the other second rod body 62.

[0070] like Figure 4 As shown, the fan blades 3 of the left ventilation channel are arranged in three intervals from top to bottom, and the second rod body 62 includes a long rod body and a short rod body. One end of the short rod body is connected to the fan blades 3, and the other end is connected to the first rod body 61. The middle part of the long rod body is connected to the fan blades 3, one end is freely set as a free end, and the other end is connected to the first rod body 61.

[0071] From top to bottom, the first fan blade 3 is connected to a short rod, and one end of the short rod is simultaneously connected to a rotary encoder 8 disposed on the pivot frame 2, so as to obtain the rotation angle of the fan blade 3 through the rotary encoder 8, thereby accurately adjusting the air volume.

[0072] The other fan blades 3 are connected to a long rod body, wherein the free end of the first long rod body is located between two proximity switch sensors 9 and swings between the two proximity switch sensors 9. The two proximity switch sensors 9 are arranged at intervals in the up and down directions and are provided on the pivot frame 2, so as to obtain the rotation position of the fan blade 3 through the proximity switch sensor 9, and then roughly adjust the air volume.

[0073] The free end of the third long rod is located between the two trigger switches 10 and swings between the two trigger switches 10. The two trigger switches 10 are arranged at intervals in the up-down direction and are arranged on the pivot frame 2. One of the trigger switches 10 is located at the extreme position of the clockwise rotation of the third long rod, and the other trigger switch 10 is located at the extreme position of the counterclockwise rotation of the third long rod. When the third long rod rotates to the extreme position, it abuts against and triggers the corresponding trigger switch 10, and the trigger switch 10 turns off the drive device 4. Preferably, the trigger switch 10 is a machine-controlled reversing valve connected to the drive device 4.

[0074] In some embodiments, Figure 3 and Figure 6 As shown, the fan blade 3 includes a blade 31 and a rotating shaft 32.

[0075] When the fan blade 3 rotates to a vertically set position, the rotating shaft 32 is located in the middle of the blade 31 along the vertical direction. The top and bottom of the blade 31 are provided with bending portions 33. The bending portion 33 extends outward from the blade 31 along the thickness direction of the blade 31, and the extension direction of the bending portion 33 at the top is opposite to that of the bending portion 33 at the bottom. When two adjacent fan blades 3 are rotated to a vertically set position, the bottom bending portion 33 of the upper blade 31 abuts against the lower end of the top bending portion 33 of the lower blade 31 to ensure that the multiple fan blades 3 can make the air volume of the ventilation channel zero and ensure the stability of the multiple fan blades 3 at this time.
