Description

Technical Field

[0001] The present invention belongs to the technical field of aviation obstruction lights, and particularly relates to an aviation obstruction light that is convenient for heat dissipation. Background Art

[0002] An aviation obstruction light, also known as an aid-to-navigation lighting device, is a special type of lamp that marks obstacles and belongs to the aid-to-navigation lighting equipment industry. Aviation obstruction lights are a type of lamp under its category. To distinguish them from general-purpose lighting fixtures, aviation obstruction lights do not stay on constantly but flash. Low-intensity aviation obstruction lights stay on constantly, while medium-intensity and high-intensity aviation obstruction lights flash. The flashing frequency is not less than 20 times per minute and not more than 60 times per minute. The function of aviation obstruction lights is to show the outline of the structure, enabling aircraft operators to judge the height and outline of the obstacles and playing a warning role.

[0003] When installing medium-intensity and high-intensity aviation obstruction lights on high towers, it is necessary to ensure the horizontality of the aviation obstruction lights during installation. In the prior art, when adjusting the horizontality of the aviation obstruction lights, it is achieved through a base. The base is provided with two sets of upper and lower fixing plates. One end of the two sets of fixing plates is rotatably connected, and the other end is fixed through an arc-shaped groove and bolts after the angle adjustment of the fixing plates is completed. However, in the above solution, during adjustment, since it is necessary to manually determine the horizontal angle, there will be a large angle between the bottom of the aviation obstruction light and the horizontal line after the adjustment is completed, and when fixing with bolts, the angle will also increase, thus affecting the installation effect of the aviation obstruction light.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0048] As Figure 1-11As shown in the figure, an aviation obstruction light facilitating heat dissipation includes an aviation obstruction light body 1 with a corrugated plate 9 fixed at the bottom. Two mirror - set first adjusting plates 2 are arranged at the bottom of the aviation obstruction light body 1. First fixing plates 8 are rotatably connected to the opposite sides of the two first adjusting plates 2. Two arc - shaped through - slots are formed on the side of the first fixing plate 8 with the rotation center of the first adjusting plate 2 as the center. The two arc - shaped through - slots include a first arc - shaped through - slot 11 and a second arc - shaped through - slot 12. The mid - point of the first arc - shaped through - slot 11, the mid - point of the second arc - shaped through - slot 12, and the rotation center of the first adjusting plate 2 are located on the same straight line. A horizontal adjusting component 5 meshing with the two arc - shaped through - slots is fixed on the two first adjusting plates 2. The horizontal adjusting component 5 is flush with the lower side of the aviation obstruction light body 1. The horizontal adjusting component 5 can drive the first adjusting plate 2 to rotate and displace. When the lower side of the aviation obstruction light body 1 is horizontally level transversely, the horizontal adjusting component 5 drives the first adjusting plate 2 to displace towards the adjacent first fixing plate 8 so that the first fixing plate 8 contacts the first adjusting plate 2 and rotates to limit the position.

[0049] An installation plate 4 is fixed to the lower side of the first fixing plate 8. A second adjusting plate 10 and a second fixing plate 3 are arranged on the lower side of the installation plate 4. A horizontal adjusting component 5 is fixed on the second adjusting plate 10. The connection and positional relationship among the second adjusting plate 10, the second fixing plate 3, and the horizontal adjusting component 5 are the same as the connection and positional relationship among the first adjusting plate 2, the first fixing plate 8, and the horizontal adjusting component 5. When the lower side of the aviation obstruction light body 1 is horizontally level longitudinally, the horizontal adjusting component 5 drives the second adjusting plate 10 to displace towards the adjacent second fixing plate 3. The second fixing plate 3 and the first fixing plate 8 are arranged in a cross - shape. A hanging plate 6 is fixed to the lower side of the second fixing plate 3. A hook bolt 7 is arranged on the hanging plate 6. One end of the hanging plate 6 is U - shaped, and the hook bolt 7 is arranged at the end of the hanging plate 6 away from the U - shaped end.

[0050] During use, hang the U - shaped end of the hanging plate 6 on the angle steel, and then hang the hanging plate 6 on the angle steel through the hook bolt 7. At this time, the hanging plate 6 is fixed. Then, adjust the horizontal angle of the second adjusting plate 10 through the horizontal adjusting component 5. At this time, the horizontal adjusting component 5 on the second adjusting plate 10 is flush with the lower side of the installation plate 4. When the lower side of the installation plate 4 is horizontally level longitudinally, the lower side of the aviation obstruction light body 1 is horizontally level longitudinally. Then, the horizontal adjusting component 5 controls the second adjusting plate 10 to contact the first adjusting plate 2 and rotate to limit the position. After that, adjust the first adjusting plate 2 and the second adjusting plate 10 through the horizontal adjusting component 5 according to the above process. After adjustment, the aviation obstruction light is fixed.

[0051] Through the setting of the corrugated plate 9, the aviation obstruction light body 1 can achieve rapid heat dissipation, ensuring the normal operation of the aviation obstruction light.

[0052] Both the first adjusting plate 2 and the second adjusting plate 10 are fixedly provided with engaging teeth 201 on their sides. Both the first fixing plate 8 and the second fixing plate 3 are fixedly provided with locking teeth 81 that engage with the engaging teeth 201. The engaging teeth 201 are arranged in a fan-shaped array centered on the rotation center of the first adjusting plate 2 or the second adjusting plate 10 at the first arc-shaped through groove 11 and the second arc-shaped through groove 12. And when the horizontal adjusting component 5 does not push the first adjusting plate 2 or the second adjusting plate 10 to move towards the first fixing plate 8 or the second fixing plate 3, the engaging teeth 201 and the locking teeth 81 are not engaged.

[0053] In this embodiment, the horizontal adjusting component 5 includes a fixed housing 55 fixed on the first adjusting plate 2, two groups of follower columns 525 rotatably arranged inside the fixed housing 55, a transmission component arranged inside the follower columns 525, an adjusting and locking component located on the follower columns 525, and a horizontal control component. Each group of follower columns 525 has two and is arranged coaxially. The follower columns 525 are connected to the horizontal control component;

[0054] The horizontal control component can lock the follower columns 525 when the bottom of the aviation obstruction lamp body 1 is horizontal, so that the follower columns 525 cannot rotate;

[0055] The adjusting and locking component can drive the horizontal control component through the transmission component. The adjusting and locking component engages with the arc-shaped through groove and can displace along the arc-shaped through groove. And when the follower columns 525 are locked, the transmission component controls the adjusting and locking component to enter a clamping state, so that the adjusting and locking component no longer displaces when rotating and pushes the first adjusting plate 2 into contact with the first fixing plate 8 and rotates to a limited position;

[0056] The adjusting and locking components on the two groups of follower columns 525 are in transmission with each other;

[0057] During use, the operator drives the adjusting and locking component to rotate clockwise by a wrench or other tool. At this time, the adjusting and locking component drives the horizontal control component to work through the transmission component. The adjusting and locking component moves along the first arc-shaped through groove 11 or the second arc-shaped through groove 12. As the adjusting and locking component moves, the first adjusting plate 2 or the second adjusting plate 10 rotates and moves upward. When the bottom of the aviation obstruction lamp is longitudinally or horizontally level, the horizontal control component locks the follower columns 525. Under the action of the follower columns 525, the transmission component and the adjusting and locking component rotate clockwise to a limited position. At this time, the operator reverses the adjusting and locking component. The transmission component reverses and does not transmit with the horizontal control component. At this time, the transmission component pushes the adjusting and locking component to work. When the adjusting and locking component rotates counterclockwise, it pushes the first adjusting plate 2 or the second adjusting plate 10 to displace towards the first fixing plate 8 or the second fixing plate 3, so that the locking teeth 81 and the engaging teeth 201 are engaged.

[0058] In this embodiment, the horizontal control component includes a reciprocating lead screw 512, a reciprocating slider 552 arranged on the reciprocating lead screw 512, a ball 551, a vertical cylinder 514 fixed on a fixed housing 55, and a movable cylinder 517 fixed on the top of the vertical cylinder 514. The top of the movable cylinder 517 is horizontal with the bottom of the aviation obstruction light body 1 or the bottom of the mounting plate 4. The reciprocating slider 552 is provided with a groove larger than the radius of the ball 551. The vertical cylinder 514 is located above the groove and communicates with the movable cylinder 517. When the movable cylinder 517 is horizontal, the ball 551 enters the groove from the movable cylinder 517 and the vertical cylinder 514.

[0059] An activity cavity 511 for the reciprocating slider 552 to reciprocate is provided inside the fixed housing 55. Cavities 513 are provided at both ends of the reciprocating lead screw 512 on the fixed housing 55. The cavities 513 are located on both sides of the activity cavity 511. A cylinder 508 coaxially fixed with a follower column 525 is provided inside the cavity 513. The cylinder 508 is driven by a bevel gear set with the reciprocating lead screw 512.

[0060] During use, the adjustment locking component drives the cylinder 508 to rotate through the transmission component and the follower column 525. The cylinder 508 drives the reciprocating lead screw 512 to reciprocate. As the first adjustment plate 2 or the second adjustment plate 10 rotates and displaces, the bottom of the aviation obstruction light body 1 or the bottom of the mounting plate 4 gradually becomes horizontal. When it is horizontal, the ball 551 falls from the movable cylinder 517 and the vertical cylinder 514 into the groove. At this time, the reciprocating slider 552 cannot reciprocate under the action of the ball 551, and the follower column 525 cannot continue to rotate, and the follower column 525 completes locking.

[0061] In this embodiment, two bevel-shaped inclined surfaces 515 are mirror-symmetrically arranged at the inner bottom of the movable cylinder 517 with the vertical cylinder 514 as the center, so that when the top of the movable cylinder 517 is horizontal, the ball 551 rolls along the inclined surface 515 into the vertical cylinder 514. The included angle between the inclined surface 515 and the horizontal line 516 does not exceed 1°, and the smaller the better, but it should be sufficient to support the ball 551 to move along the inclined surface 515 into the vertical cylinder 514 when the movable cylinder 517 is horizontal.

[0062] During use, through the setting of the inclined surface 515, it is ensured that the ball 551 can accurately fall into the vertical cylinder 514, thereby ensuring the displacement limit of the reciprocating slider 552.

[0063] In this embodiment, a pneumatic housing 509 is fixed inside the activity cavity 511. A fan wheel 510 coaxially fixed with the reciprocating lead screw 512 is provided inside the pneumatic housing 509. The side surface of the fan wheel 510 contacts the pneumatic housing 509 to form a plurality of pneumatic cavities. The top and bottom of the pneumatic housing 509 are both communicated with the upper and lower side surfaces of the fixed housing 55. A driving barrel 526 communicated with the pneumatic housing 509 is fixed on the top of the fixed housing 55 to drive the fan wheel 510 to rotate.

[0064] The structures of the fan wheel 510 and the pneumatic housing 509 are those of a pneumatically driven device in the prior art, such as a pneumatic servo motor, for enabling the drive barrel 526 to drive the fan wheel 510 to rotate;

[0065] The drive barrel 526 is composed of a barrel body, a piston, and a drive rod. The barrel body is connected to the pneumatic housing 509. By pressing down or pulling up the piston, gas is enabled to enter the pneumatic housing 509 or be discharged from the pneumatic housing 509, thereby realizing the forward and reverse rotation of the fan wheel 510;

[0066] When the ball 551 needs to be taken out, by pressing down or pulling up the drive rod, the fan wheel 510 rotates forward or backward. The forward and reverse rotation of the fan wheel 510 drives the reciprocating lead screw 512 to rotate forward and backward, and the reciprocating lead screw 512 drives the reciprocating slider 552 to displace, so that the ball 551 can be disengaged from the groove, thus facilitating secondary use.

[0067] In this embodiment, a threaded cavity 504 is axially formed inside the follower column 525. A displacement cavity 518 is provided on one side of the threaded cavity 504 inside the follower column 525. The displacement cavity 518 and the threaded cavity 504 are coaxially arranged with the follower column 525. The transmission assembly includes a fixed disk 507 sealed and fixed on the follower column 525, a transmission disk 51 slidably connected in the displacement cavity 518, an adjusting piston 505 threadedly connected in the threaded cavity 504, and a control valve 524 fixed on the fixed housing 55. The transmission disk 51 is elastically connected to the adjusting piston 505. The adjusting piston 505 is in one-way transmission with the transmission disk 51. A plurality of plug-in blocks are elastically inserted on the side surface of the transmission disk 51 through springs. The plug-in blocks are prevented from disengaging from the transmission disk 51 by the balls 551 and the chutes. The fixed disk 507 is provided with a plurality of holes for the plug-in blocks to be inserted, so as to drive the fixed disk 507 to rotate. The fixed disk 507 is connected to the cylinder 508. The fixed disk 507 is located in the displacement cavity 518. The displacement cavity 518 communicates with the cavity 513, and the threaded cavity 504 is arranged on the side of the displacement cavity 518 away from the cavity 513);

[0068] The adjusting piston 505 is in transmission with the adjusting and locking assembly. The inner wall of the fixed housing 55 is annularly provided with a communication channel 52. A communication hole opened on the threaded cavity 504 is arranged in the communication channel 52. The communication hole is located between the transmission disk 51 and the adjusting piston 505. The communication channel 52 communicates with the adjusting and locking assembly through the control valve 524;

[0069] The side of the threaded cavity 504 away from the displacement cavity 518 communicates with the adjusting and locking assembly;

[0070] The adjusting piston 505 is provided with a section of hard threaded column, and the rest is a threaded piston in contact and sealed with the threaded cavity 504;

[0071] When in use, the adjusting locking assembly drives the cylinder 508 and the follower column 525 to rotate through the adjusting piston 505, the transmission disk 51, and the fixed disk 507, thereby realizing the driving of the reciprocating screw 512. When the reciprocating screw 512 rotates to a limit, the personnel rotates the adjusting locking assembly counterclockwise, and the adjusting piston 505 rotates and moves. Since the transmission disk 51 and the adjusting piston 505 are transmitted in one direction, the transmission disk 51 does not rotate until the adjusting piston 505 drives the plug-in block to disengage from the hole on the fixed disk 507. When the adjusting piston 505 moves, negative pressure is formed between the adjusting piston 505 and the fixed disk 507, and the threaded cavity 504 on the side of the adjusting piston 505 away from the fixed disk 507 forms high-pressure gas. The high-pressure gas drives the adjusting locking assembly to work. The adjusting locking assembly continues to work and gradually pushes the first adjusting plate 2 or the second adjusting plate 10 to contact the first fixed plate 8 and the second fixed plate 3 and rotate to a limit.

[0072] In this embodiment, a transmission column 506 is fixed to the axis of the side of the adjusting piston 505, and a transmission rod 5061 is inserted into the transmission column 506. The transmission rod 5061 transmits to the transmission column 506. The transmission rod 5061 transmits to the transmission plate 51 in one direction through a ratchet pawl structure. A spring that contacts the transmission rod 5061 is arranged on the side of the transmission column 506. The transmission rod 5061 and the transmission column 506 are slidably connected through the ball 551 and the slide groove, so that the transmission rod 5061 cannot be separated from the transmission column 506.

[0073] When in use, the transmission between the adjusting piston 505 and the transmission plate 51 is realized through the transmission rod 5061 and the transmission column 506, and the transmission plate 51 can continue to rotate when the plug-in block is not plugged into the hole of the fixed plate 507 through the setting of the spring, thereby ensuring the plug-in connection between the plug-in block and the fixed plate 507.

[0074] In this embodiment, the adjusting locking assembly includes a connecting assembly arranged on the follower column 525, a displacement assembly arranged in the arc-shaped through groove, a transmission gear 50 and two clamping rings 56. The connecting assembly is rotatably plugged into the follower column 525 and is transmitted to the adjusting piston 505. The control valve 524 is connected to the connecting assembly to control the extension or retraction of the connecting assembly.

[0075] The displacement assembly is plugged into the connection assembly and transmits power to the connection assembly. The transmission gear 50 is fixed on the displacement assembly, and the two transmission gears 50 on the same side are meshed with each other.

[0076] One of the clamping rings 56 is located on the displacement assembly, and the other clamping ring 56 is located on the connecting assembly. The connecting assembly can push the clamping ring 56 to move to the displacement assembly, and the displacement assembly can drive the two clamping rings 56 to move toward or away from each other, so as to drive the first adjustment plate 2 to move toward the adjacent first fixed plate 8;

[0077] On the opposite sides of two follower columns 525 in the same group, a plurality of sealing holes are formed. Sealing sleeves 562 are hermetically inserted into the sealing holes. An extrusion rod 561 fixed to an adjacent clamping ring 56 is hermetically inserted into the sealing sleeves 562. The sealing holes communicate with the side of the threaded cavity 504 away from the adjusting piston 505.

[0078] During use, an operator drives the connection assembly to rotate through the displacement assembly. The connection assembly drives the adjusting piston 505 to rotate. When the follower column 525 is locked, the displacement assembly rotates in the reverse direction. The connection assembly drives the adjusting piston 505 to rotate in the reverse direction. At this time, the adjusting piston 505 displaces and generates high-pressure gas. The high-pressure gas pushes the extrusion rod 561 to move. The extrusion rod 561 pushes the clamping ring 56 to move. The clamping ring 56 moves onto the displacement assembly. The displacement assembly drives the clamping ring 56 connected with the extrusion rod 561 to move, and through the two clamping rings 56, the first adjusting plate 2 contacts the second fixing plate 3 or the second adjusting plate 10 contacts the second fixing plate 3 and rotates to be limited.

[0079] After fixation, the negative-pressure gas between the adjusting piston 505 and the fixed disk 507 drives the connection assembly to lock the follower column 525 through the control valve 524. At this time, the connection assembly can be separated from the displacement assembly. When reinstallation is required, one of the connection assemblies is inserted into the displacement assembly, and then the displacement assembly is rotated clockwise, so that the adjusting piston 505 displaces and the air pressure between the adjusting piston 505 and the fixed disk 507 increases. The connection assembly extends and is inserted into the displacement assembly.

[0080] In this embodiment, mounting holes are formed on the opposite sides of two follower columns 525 in the same group. On the inner wall of the mounting hole, two annular slots 5251 communicating with the communication channel 52 are coaxially formed on the circular side surface. At the center of the mounting hole, an axial hole is formed along the axis of the follower column 525. The connection assembly includes an intermediate column 502 inserted into the axial hole, a transmission cylinder 57 sleeved outside the intermediate column 502, and a displacement cylinder 53 sleeved on the outer side surface of the transmission cylinder 57.

The displacement cylinder 53, the transmission cylinder 57, and the intermediate column 502 are rotatably connected. The annular slots 5251 are polygonal ring holes, so that the follower column 525 can drive the transmission cylinder 57 and the displacement cylinder 53 to rotate.

[0081] A transmission hole 5021 is formed on the side surface of the intermediate column 502. A polygonal insertion rod 527 connected with the adjusting piston 505 is inserted and transmitted through the transmission hole 5021. The depth of the transmission hole 5021 is greater than the length of the insertion rod 527. On the other side surface of the intermediate column 502, a driving gear 5022 in transmission with the displacement assembly is coaxially fixed.

[0082] The circumferential side surface of the transmission cylinder 57 is provided with a notch, and a middle gear 522 that is in transmission connection with the driving gear 5022 is rotatably connected in the notch;

[0083] A transmission ring 523 that is rotatably connected to the side surface of the displacement cylinder 53 and is inserted on the displacement assembly is in meshing transmission connection with the displacement assembly and the middle gear 522. Both the driving gear 5022 and the transmission cylinder 57 are inserted and in transmission connection with the displacement assembly, and the other end of the middle gear 522 is rotatably inserted on the displacement assembly;

[0084] During use, the displacement assembly rotates and drives the follower column 525 to rotate through the driving gear 5022, the middle column 502, the insertion rod 527, the adjusting piston 505, the transmission disc 51, and the fixed disc 507. The follower column 525 drives the displacement cylinder 53 and the transmission cylinder 57 to rotate. The transmission cylinder 57 rotates and drives the displacement assembly to move along the arc-shaped through groove. When the follower column 525 is locked, the displacement assembly rotates in the reverse direction. At this time, the transmission cylinder 57 no longer rotates, the driving gear 5022 and the middle column 502 rotate, the adjusting piston 505 moves and moves through the insertion rod 527, high-pressure gas is generated in the threaded cavity 504, and the high-pressure gas pushes the clamping ring 56 to move onto the displacement assembly. Since the transmission cylinder 57 no longer rotates, the displacement assembly does not move along the arc-shaped through groove at this time. The driving gear 5022 is in transmission connection with the middle gear 522, the middle gear 522 drives the displacement assembly through the transmission ring 523, and the displacement assembly drives the clamping ring 56 to move and gradually makes the first adjusting plate 2 contact and rotate with the first fixing plate 8 or the second adjusting plate 10 contact and rotate with the second fixing plate 3 for limiting;

[0085] After that, the control valve 524 is used to control the communication between the adjusting piston 505 and the fixed disc 507 to the annular slot 5251. The displacement cylinder 53, the transmission cylinder 57, the middle column 502, and the driving gear 5022 move and disengage from the displacement assembly, so that the components other than the displacement assembly can be removed;

[0086] When reinstallation is required, the driving gear 5022 is inserted into the displacement assembly, and the displacement assembly is rotated clockwise. At this time, the rotating gear drives the adjusting piston 505 to move through the middle column 502. The gas between the adjusting piston 505 and the fixed disc 507 gradually enters the annular slot 5251, so that the displacement cylinder 53, the transmission cylinder 57, the middle column 502, and the driving gear 5022 are reconnected to the displacement assembly.

[0087] In this embodiment, the displacement assembly includes a follower cylinder 572 located in the arc-shaped through groove, an adjusting gear 501 fixed to the follower cylinder 572, two threaded cylinders 58 rotatably connected to the outer side surface of the follower cylinder 572, and a driving shaft 59 rotatably connected to the inside of the follower cylinder 572. The transmission gear 50 is fixed to the driving shaft 59. The driving shaft 59 is provided with a polygonal hole 591, and a polygonal column 5023 fixed on the driving gear 5022 is inserted into the polygonal hole 591;

[0088] Two threaded cylinders 58 are arranged on both sides of the adjusting gear 501. The threaded cylinder 58 adjacent to the transmission ring 523 is provided with an arc-shaped hole 581. The transmission cylinder 57 is fixed with an arc-shaped block 5231 inserted into the arc-shaped hole 581. The other threaded cylinder 58 is fixed on the driving shaft 59.

[0089] The follower cylinder 572 is provided with a plug hole 573. The transmission cylinder 57 is fixed with a plug block inserted into the plug hole 573. Tooth grooves 574 are provided on the follower cylinder 572 between adjacent plug holes 573.

[0092] During use, a wrench is inserted into the hexagonal slot or the hexagonal nut is placed in the wrench, and then the driving shaft 59 is rotated. The driving shaft 59 drives the driving gear 5022 to rotate. The transmission cylinder 57 drives the follower cylinder 572 to rotate. The follower cylinder 572 rotates to drive the adjusting gear 501 to move along the first arc-shaped through groove 11 and the second arc-shaped through groove 12. When the follower column 525 cannot rotate, the follower column 525 cannot rotate. Then the driving shaft 59 is reversed. The driving shaft 59 drives the transmission ring 523 to rotate through the driving gear 5022 and the intermediate tooth 522. The transmission ring 523 drives the adjacent threaded cylinder 58 to rotate. While the threaded cylinder 58 rotates, the clamping ring 56 provided with the pressing rod 561 moves towards the threaded cylinder 58 and is threadedly connected to the threaded cylinder 58. At this time, the clamping ring 56 moves and contacts the first adjusting plate 2 or the second adjusting plate 10. Then the pressing rod 561 continues to move and disengages from the sealing sleeve 562. At this time, the clamping ring 56 will not rotate due to the friction with the first adjusting plate 2 or the second adjusting plate 10 and continues to displace, so that the first adjusting plate 2 contacts and rotates with the first fixing plate 8 or the second adjusting plate 10 contacts and rotates with the second fixing plate 3 for limiting;

[0093] Preferably, the first arc-shaped through groove 11 and the second arc-shaped through groove 12 are both provided with teeth meshing with the adjusting gear 501.
