Description

Technical Field

[0001] This utility model relates to the field of outdoor and indoor gimbal technology, specifically a multi-functional gimbal for power line carrier signal transmission. Background Technology

[0002] 1. Commercially available outdoor pan-tilt units (PTZs) typically use serial communication protocols such as RS-232, RS-422, and RS-485 to transmit data. Some devices support higher-level control protocols like PELCO-D, PELCO-P, and VISCA, while network-type PTGs use the TCP / IP protocol. The PTG and its top-mounted devices require separate power cables, and communication between the PTG and remote controller also requires separate cabling, which is costly and complex. The serial communication protocols (RS-232, RS-422, RS-485) and network communication protocols (TCP / IP) used by conventional PTGs each have their advantages in terms of cabling convenience. RS-485 cabling is convenient and relatively inexpensive, suitable for long-distance multi-device connections; RS-232 cabling is simple but only suitable for short distances; TCP / IP cabling is flexible but more expensive. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides the following technical solution: a multi-functional gimbal for power line carrier signal transmission, comprising a gimbal middle frame, a gimbal lower cover, and a gimbal upper cover, wherein the gimbal lower cover is fixedly installed at the bottom of the gimbal middle frame, and the gimbal upper cover is fixedly installed at the top of the gimbal middle frame; a motor bracket is fixedly installed inside the gimbal middle frame, an encoder and a geared motor are fixedly installed on the motor bracket, and a first gear is fixedly installed on the output shaft of the geared motor; a motor drive board is fixedly installed on the outer shell of the geared motor through a motor drive board protective cover, and the motor drive board is located inside the motor drive board protective cover; a power line carrier module and a power supply module are also provided inside the gimbal middle frame, and both the power line carrier module and the power supply module are fixedly installed on the gimbal upper cover; a remote control for controlling the geared motor is also included.

[0004] Preferably, the lower cover of the gimbal is sealed with a waterproof Type-C connector and two waterproof two-core connectors.

[0005] Preferably, the gimbal top cover has a gimbal rotating spindle rotatably mounted inside via two bearings, wherein the junction between the journal of the gimbal top cover and the gimbal rotating spindle is sealed by a TG oil seal.

[0006] Preferably, the two bearings are fixed to the gimbal rotation spindle by bearing retaining rings to prevent the bearings from separating from the bearing retaining rings; a gimbal rotation cover is fixed to one end of the gimbal rotation spindle above the gimbal top cover, and a gimbal top bracket is fixed to the gimbal rotation cover.

[0007] Preferably, the bearing is pressed onto the gimbal cover by the second bearing end cover, and the bottom end of the gimbal rotating main shaft passes through the second bearing end cover. A second gear that meshes with the first gear is fixed at the end of the gimbal rotating main shaft away from the gimbal rotating cover.

[0008] Compared with the prior art, this utility model has the following advantages: (1) In actual use, this gimbal only needs a 220V power line to realize the linkage between the remote control and the gimbal, which greatly reduces the cost of long-distance wiring; (2) After the internal auxiliary structure and circuit conversion, this gimbal can output 220V, 15V2A power to the equipment on the gimbal, making the installation of the gimbal and the product simpler and more convenient.

Detailed Implementation

[0013] The following is in conjunction with the appendix Figures 1-3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0014] This utility model provides a multi-functional pan-tilt unit (PTZ) for power line carrier signal transmission, including a pan-tilt frame 1, a lower pan-tilt cover 2, and an upper pan-tilt cover 3. The lower pan-tilt cover 2 is fixedly installed at the bottom of the pan-tilt frame 1, and the upper pan-tilt cover 3 is fixedly installed at the top of the pan-tilt frame 1. A motor bracket 14 is fixedly installed inside the pan-tilt frame 1, and an encoder 15 and a geared motor 12 are fixedly installed on the motor bracket 14. A first gear 13 is fixedly installed on the output shaft of the geared motor 12. A motor drive board 18 is fixedly installed on the outer shell of the geared motor 12 through a motor drive board protective cover 11, and the motor drive board 18 is located inside the motor drive board protective cover 11. A power line carrier module 16 and a power supply module 17 are also provided inside the pan-tilt frame 1, and both the power line carrier module 16 and the power supply module 17 are fixedly installed on the upper pan-tilt cover 3. It also includes a remote control for controlling the geared motor 12. The remote control contains the power line carrier module. A waterproof Type-C connector 22 and two waterproof two-pin connectors 21 are sealed and fixedly installed on the lower pan-tilt cover 2. Inside the gimbal cover 3, a gimbal rotation spindle 34 is rotatably mounted via two bearings 35. The junction between the journal of the gimbal cover 3 and the gimbal rotation spindle 34 is sealed by a TG oil seal 33. The two bearings 35 are fixed to the gimbal rotation spindle 34 by bearing retaining rings 36 to prevent them from separating from the retaining rings 36. A gimbal rotation cover 32 is fixed to one end of the gimbal rotation spindle 34 above the gimbal cover 3, and a gimbal top bracket 31 is fixed to the gimbal rotation cover 32. The bearings 35 are pressed against the gimbal cover 3 by a second bearing end cover 38, and the bottom end of the gimbal rotation spindle 34 passes through the second bearing end cover 38. A second gear 37, meshing with the first gear 13, is fixed to the end of the gimbal rotation spindle 34 away from the gimbal rotation cover 32.

[0015] To address the cost and complexity of long-distance cabling, the pan-tilt unit (PTZ) and remote controller communicate using power line carrier (PLC). Only one power cable is needed to power the PLC and related equipment for both power supply and communication. PLC Power Supply: The PLC, through its internal structure and power conversion, can supply power to the internal geared motor 12, as well as provide 220V and 15V power to the devices mounted on it. PLC Transmission: The PLC is powered by the geared motor 12. A first gear 13 is mounted on the output shaft of the geared motor 12, which drives a second gear 37 to rotate. The second gear 37 then drives the PLC's rotating main shaft 34, ultimately rotating the PLC's rotating cover 32 and the top support 31. PLC and Remote Control: The PLC and remote controller are effectively connected via the PLC module. An encoder 15 is installed on the motor support 14 to detect the angle of the PLC's rotating main shaft 34. The potentiometer knob on the remote controller synchronizes with the PLC's rotating main shaft 34, providing 270-degree rotation.
