Description

Technical Field

[0001] This utility model relates to the field of power line galloping monitoring technology. More specifically, this utility model relates to a dedicated pan-tilt unit for power line galloping monitoring. Background Technology

[0002] Overhead transmission lines play a crucial role in power systems, transmitting electrical energy. Line galloping can seriously threaten the normal operation of the power grid, necessitating monitoring of transmission line galloping. In recent years, with the development of image processing technology, traditional inertial sensor-based line galloping monitoring equipment has been gradually replaced by video-based conductor galloping monitoring equipment.

[0003] Video-based conductor galloping monitoring equipment typically involves mounting a pan-tilt unit (PTZ) on the tower. The PTG unit rotates the image acquisition device, adjusting its shooting angle. While portable conductor galloping monitoring equipment has emerged in recent years, the lack of dedicated PTG units forces the use of existing ones. This results in large, limited-load PTG units for portable equipment, particularly with low axial rotation adjustment precision, making it difficult to meet the demands of conductor galloping monitoring. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated pan-tilt unit for monitoring line galloping. It has a compact structure and can output two degrees of freedom of rotation, allowing adjustment of the shooting angle of the image acquisition device in both horizontal and vertical directions.

Detailed Implementation

[0042] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0043] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] like Figure 1 As shown, an embodiment of this utility model provides a dedicated pan-tilt unit for monitoring line galloping, comprising:

[0045] A support, on which a first rotating mechanism 2 and a second rotating mechanism 3 are provided;

[0046] Mounting base 4 is connected to the first rotating mechanism 2 in a transmission manner, and the first rotating mechanism 2 drives the mounting base 4 to rotate in a first direction;

[0047] The rotating base 5 has one end connected to the second rotating mechanism 3, and the second rotating mechanism 3 drives the mounting base 4 to rotate in a second direction perpendicular to the first direction.

[0048] The connecting seat 6 is detachably connected to the other end of the rotating seat 5.

[0049] In this embodiment, the dedicated gimbal for monitoring line galloping is fixed by the mounting base 4. During use, the mounting base is fixed downwards in the desired position. A connecting flange is provided at the end of the mounting base 4 away from the rotating base 5. Corresponding connecting flanges are also provided on autonomous vehicles, drones, etc. The two connecting flanges are connected by multiple bolts, thus fixing the dedicated gimbal for line galloping monitoring onto the autonomous vehicle, drone, or other equipment. A connecting base 6 is pre-fixed on the image acquisition device. When fixing the image acquisition device to the dedicated gimbal for line galloping monitoring, only the connecting base 6 needs to be connected to the other end of the rotating base 5, reducing the difficulty of connecting the image acquisition device to the gimbal and making it more suitable for high-altitude operations. When the first rotating mechanism 2 is working, it drives the mounting base 4 to rotate. However, since the mounting base 4 is fixed in position, the first rotating mechanism 2 will rotate relative to the mounting base 4 along a first direction, thereby enabling the image acquisition device to rotate along the first direction. When the second rotating mechanism 3 is working, it drives the rotating base 5 to rotate along a second direction, thereby enabling the image acquisition device to rotate along the second direction. In actual use, a counterweight can be set on the support according to the weight of the image acquisition equipment of the line galloping observation equipment, so that the load on the first rotating mechanism 2 is even.

[0050] Preferably, as another embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the other end of the rotating seat 5 is provided with an installation port 51, and the two side walls of the installation port 51 are provided with limiting grooves 52. The connecting seat 6 is provided with an installation block 61 corresponding to the installation port 51. The two sides of the installation block 61 are provided with protrusions 62 corresponding to the limiting grooves 52. The installation block 61 is inserted into the installation port 51 and is connected and fixed to the rotating seat 5 through a connector.

[0051] In this embodiment, when the mounting block 61 is inserted into the mounting opening 51, the two protrusions 62 are respectively inserted into the two limiting grooves 52 to limit the movement trajectory of the mounting block 61, so that the mounting block 61 can only slide along the insertion direction within the mounting opening 51. Then, after the mounting block 61 slides into place, it is connected and fixed to the rotating seat 5 through a connector. Specifically, as one embodiment, the connector is a first bolt. A first threaded hole 63 is provided at the end of the mounting block 61 away from the image acquisition device. Then, a through hole 53 corresponding to the first threaded hole 63 is provided in the mounting opening 51. After the mounting block 61 is inserted into the mounting opening 51 and slides into place, the through hole 53 on the mounting block 61 communicates with the first threaded hole 63. The first bolt passes through the through hole 53 and is threaded into the first threaded hole 63. Tightening the first bolt can fix the connector 6 and the rotating seat 5.

[0052] Preferably, as another embodiment of this utility model, such as Figure 2 As shown, the mounting port 51 is a trapezoidal mounting port 51.

[0053] In this embodiment, the mounting port 51 is trapezoidal, and the mounting block 61 is also trapezoidal. The opening of the trapezoidal mounting port 51 gradually narrows, so when the mounting block 61 slides inward within the mounting port 51, it can no longer slide inward when its two sides are in contact with the two sides of the mounting port 51. At this point, the mounting block 61 has slid into place, and the through hole 53 on the mounting block 61 communicates with the first threaded hole 63, thus automatically positioning the mounting block 61 within the mounting port 51.

[0054] Preferably, as another embodiment of this utility model, such as Figure 1 As shown, the support includes:

[0055] Positioning plate 11;

[0056] The first bracket 12 is disposed on one side of the positioning plate 11 to fix the first rotating mechanism 2;

[0057] The second bracket 13 is disposed on the other side of the positioning plate 11 to fix the second rotating mechanism 3.

[0058] Preferably, as another embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the first rotating mechanism 2 includes:

[0059] The first motor 21 is fixed to the positioning plate 11;

[0060] The first reducer 22 is fixed on the first bracket 12, and its output end is connected to the mounting base 4;

[0061] A connecting component for connecting the output terminal of the first motor 21 and the input terminal of the first reducer 22.

[0062] In this embodiment, the first motor 21 is connected to the first reducer 22 via a connecting assembly. When the first motor 21 is working, it drives the mounting base 4 to rotate via the first reducer 22. The second rotating mechanism 3 adopts the same structure as the first rotating mechanism 2, and the structure of the second rotating mechanism 3 will not be described in detail.

[0063] Preferably, as another embodiment of this utility model, such as Figures 5-6 As shown, the connection component includes:

[0064] The first flange 23 is connected to the output end of the first motor 21, and the end of the first flange 23 away from the first motor 21 is provided with a non-cylindrical positioning rod 24.

[0065] The second flange 25 is connected to the output end of the first reducer 22, and its middle part is provided with a positioning hole 26 corresponding to the positioning rod 24;

[0066] Multiple second bolts 27 are provided. The side wall of the second flange 25 is provided with at least one second threaded hole 28. The positioning rod 24 has blind holes 29 that are equal in number and correspond one-to-one with the second threaded holes 28. The second bolts 27 are threadedly installed in the second threaded holes 28. The positioning rod 24 extends into the positioning hole 26 and abuts against the bottom wall of the blind hole 29.

[0067] In this embodiment, the first motor 21 is a frameless servo motor, with its output end being a turntable, coaxially connected to the first flange 23; the first reducer's output end is also a turntable, coaxially connected to the second flange 25. A positioning rod 24 on the first flange 23 is inserted into a positioning hole 26 on the second flange 25. The positioning rod 24 is non-cylindrical, so it will not rotate within the second flange 25 after insertion into the positioning hole 26. After the positioning rod 24 extends into the positioning hole 26, a second bolt 27 is installed in the second threaded hole 28, with its end extending into the corresponding blind hole 29. Tightening the second bolt 27 until its end abuts against the bottom wall of the blind hole 29 on the positioning rod 24 secures the first flange 23 and the second flange 25 together.

[0068] Preferably, as another embodiment of this utility model, such as Figure 7 As shown, it also includes:

[0069] The L-shaped housing 7, the support, the first rotating mechanism 2 and the second rotating mechanism 3 are all disposed inside the L-shaped housing 7, the output ends of the first rotating mechanism 2 and the second rotating mechanism 3 both protrude from the L-shaped housing 7 and are respectively connected to the mounting base 4 and the rotating base 5 disposed outside the L-shaped housing 7.

[0070] In this embodiment, by setting an L-shaped housing 7, the first rotating mechanism 2 and the second rotating mechanism 3 are placed inside the L-shaped housing 7, and corresponding wire holes are opened on the housing. The L-shaped housing 7 plays a protective role for the first rotating mechanism 2 and the second rotating mechanism 3, so that the special pan-tilt unit used for line galloping monitoring forms a whole.

[0071] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
