Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an optical fiber transmission device for an aircraft pay-out camera. Background Art

[0002] Today, the rapid development of the drone and aerial vehicle industry and technology has led to their continuous application in various fields, such as high-definition geographic photography, environmental and topographical photography, emergency rescue, emergency relief, battlefield reconnaissance, battlefield target tracking, target strike, agricultural plant protection, and industrial hazard photography. With their low cost and high performance, drones and aerial vehicles are increasingly becoming a tool people rely on for specialized applications.

[0003] Currently, the following problems exist in the pay-out process of optical fiber for aircraft pay-out cameras:

[0004] 1. When shooting with drones or aerial vehicles, the wireless transmission of high-definition images is unstable due to the long flight distance;

[0005] 2. The wireless controllers of drones and aerial vehicles are susceptible to signal interference due to long-distance flight.

[0006] Therefore, the use of wired transmission can ensure the stability of signal transmission. To better achieve this goal, we propose an aircraft-mounted camera optical fiber transmission device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-8, an aircraft release-type camera optical fiber transmission device includes a front cover 1, a fixing plate 2, a shell 7, a tube body 3, and a turntable 5. The front cover 1, the fixing plate 2, and the shell 7 are fixedly connected in sequence. One end of the tube body 3 is fixedly sleeved with the fixing plate 2, and the other end of the tube body 3 is fixedly sleeved with the limit plate 4. A through hole 13 is opened on the turntable 5, and one end of the tube body 3 close to the limit plate 4 is rotatably sleeved in the through hole 13. A nut 6 is threadedly sleeved on one end of the tube body 3 close to the limit plate 4. The nut 6 and the limit plate 4 are located on both sides of the turntable 5. A first fixing seat 11, a second fixing seat 14, and a third fixing seat 16 are fixed on the turntable 5. A threading hole 12 is opened on the first fixing seat 11, and a first pulley 15 is rotatably installed on the second fixing seat 14. A second pulley 17 is rotatably installed on the third fixing seat 16. The end of the shell 7 away from the front cover 1 is connected with a ceramic threading tube 18. The ceramic threading tube 18 can prevent the increase of the falling force of the line when the drone and the aerial aircraft are raised. And the shell 7 is cut by the fast pay-off speed, affecting the overall performance. Several first connecting bosses 9 are fixed on the front cover 1, several second connecting bosses 10 are fixed on the fixing plate 2, and several third connecting bosses 19 are fixed on the shell 7. The first connecting boss 9, the second connecting boss 10, and the third connecting boss 19 are fixedly connected by a bolt assembly, which can enhance the overall bonding of the product and solve the problem that when the product is horizontally installed in a drone or an aerial vehicle, the tail of the optical fiber 20 winding reel falls and contacts with the outer shell device to generate friction, resulting in poor optical fiber pay-off and increased optical fiber breakage caused by pulling. The rotating shaft of the first pulley 15 is rotatably connected to the second fixed seat 14 through a bearing, and the rotating shaft of the second pulley 17 is rotatably connected to the second fixed seat 14 through a bearing, which reduces the friction when the optical fiber 20 comes out and increases the pay-off speed and stability. A camera mounting hole 8 is provided on the front cover 1, and the camera mounting hole 8 is used to install the camera lens.

[0029] Working principle: When in use, the camera mounting hole 8 is used to install the camera lens, the optical fiber 20 is wound on the tube body 3, and then passes through the second pulley 17, the first pulley 15, the threading hole 12 and is transmitted from the ceramic threading tube 18. During the continuous pulling out of the optical fiber 20, the turntable 5 rotates, and the optical fiber 20 is continuously released from the tube body 3; the first connecting boss 9, the second connecting boss 10, and the third connecting boss 19 are fixedly connected by a bolt assembly, which can enhance the overall bonding of the product and solve the problem of the product being installed horizontally on a drone or an aerial vehicle. The tail of the optical fiber 20 winding drum falls down and contacts the outer shell device, causing friction, resulting in poor optical fiber payout and increasing the problem of optical fiber breakage due to tension; the ceramic wire tube 18 can prevent the increase in the falling force of the line when the drone and aerial aircraft rise and the excessive payout speed from cutting the shell 7, affecting the overall performance; the rotating shaft of the first pulley 15 is rotatably connected to the second fixed seat 14 through a bearing, and the rotating shaft of the second pulley 17 is rotatably connected to the second fixed seat 14 through a bearing, which reduces the friction when the optical fiber 20 is discharged and increases the payout speed and stability.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
