Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) communication equipment technology, and more particularly to a high-speed fiber optic cable dispenser for unmanned equipment. Background Technology

[0002] Current drones are operated using radio remote control equipment and onboard program control devices, which has many advantages. However, for special environments such as underground inspections, underwater drones, unmanned vehicles, and areas with high anti-interference requirements, wireless control of drones will bring many inconveniences. Traditional fiber optic transmission has short control distances, slow cable laying speeds, and the fiber itself is heavy, making it unsuitable for use in drones and similar products. Based on these problems, this utility model proposes a high-speed fiber optic cable laying device for unmanned equipment. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A high-speed fiber optic cable dispenser for unmanned equipment, see [link / reference] Figures 1 to 4 .

[0024] It includes a cylindrical tubular outer shell 9, the rear end of which is an opening 10, and the front end of which is conical with an opening 6.

[0025] A spool 12 is fixedly installed inside the housing, and an optical fiber 13 is wound around the spool 12. A fixed disk 14 is provided at the tail end of the spool 12, and the fixed disk 14 is embedded and fixed in the opening at the tail end of the housing 9. The spool 12 is tubular, the front end of the spool is trumpet-shaped, and the inner side of the front end of the spool is conical and forms a slope surface 11.

[0026] The front end of the spool 12 is suspended and includes an optical fiber communication module 16. The optical fiber communication module 16 is installed on the fixing plate 15 inside the spool. The optical fiber communication module 16 is communicatively connected to the tail end of the optical fiber wound on the spool. At the same time, the data cable socket on the optical fiber communication module 16 extends to the outside of the fixing disk to facilitate connection with an external communication module.

[0027] Furthermore, it also includes an extended guide tube 5 and a trumpet-shaped universal connector 4. The tail end of the extended guide tube 5 is inserted into the opening of the front end 6 of the outer shell, the small end of the universal connector 4 is inserted into the front end of the extended guide tube 5, the optical fiber connector 2 is movably inserted into the front opening of the universal connector 4, and the front end 13-1 of the optical fiber passes through the universal connector 4 and the extended guide tube 5.

[0028] Furthermore, to protect the high-speed wire feeder of this design from damage to the suspended spool end during transportation, this design also includes a support buckle 8. At least two symmetrical through holes 17 are provided on the outer wall of the front part of the outer casing corresponding to the front end of the spool. The support buckle 8 is inserted into the through hole 17. The front end of the support buckle 8 forms an inwardly recessed groove 8-2. The groove buckle 8-2 is at the end of the front end of the spool and supports the suspended front end of the spool. At the same time, in order to fix each support buckle, a through opening 8-1 is also provided at the tail end of the support buckle 8. The support buckles located on the outer casing 9 are fixed by cable ties. The cable ties pass through the through openings on each support buckle in sequence to fix each support buckle 8.

[0029] Furthermore, it also includes a cover 1 that snaps onto the end of the fiber optic connector to protect the end of the fiber optic connector and prevent damage during handling.

[0030] Furthermore, it also includes a protective shell 3 wrapped around the optical fiber connector, which protects the optical fiber connector and prevents it from being damaged during transportation.

[0031] The usage process of the unmanned high-speed fiber optic cable dispenser in this design is as follows:

[0032] 1. Cut the cable ties and remove each support buckle 8 to leave the front end of the spool suspended in the air.

[0033] 2. Remove the protective shell 3 and the cover 1, and pull the fiber optic connector 2 outward to connect it to the drone.

[0034] 3. Connect the external control terminal to the data cable port on the fiber optic communication module 16.

[0035] The above steps enable the connection between the external control terminal and devices such as drones. After the drone flies out, the fiber optic cable is guided by the ramp surface 11, the extended guide tube 5, and the universal guide nozzle 4 to form a defense line. Since the spool in this design is fixed and suspended, no additional power source is needed to make the spool rotate. Therefore, the fiber optic cable laying speed is determined by the speed of the flying drone, thus achieving a high-speed defense line.

[0036] In summary, the principle of this high-speed fiber optic cable transmitter for unmanned equipment is to solve the communication problem between unmanned aerial vehicles (UAVs) and their operators using lightweight fiber optic transmission, enabling communication including image, data, and remote control links. The fiber optic communication module 16 can transmit CVBS, AHD, TVI, CVI, HDMI, H.264, H.265, or MIPI video streams, and can also transmit TTL serial port data bidirectionally with adaptive baud rates. The fiber optic communication module 16 can also be designed with a 100Mbps Ethernet port, capable of transmitting HDMI, CVBS, AHD, CVI, TVI, H.265, and other video streams, and can also transmit TTL serial port data bidirectionally with adaptive baud rates, meeting the communication needs of various devices.

[0037] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
