Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an electric power maintenance UAV device. Background Art

[0002] Power maintenance drones are specialized devices that utilize drone technology to assist or perform maintenance work on power facilities. They are primarily used to inspect, monitor, and repair power systems, such as transmission and distribution lines and substations. Equipped with high-definition cameras and infrared thermal imagers, they provide real-time information on the operating status of facilities, identifying anomalies and enabling prompt repair and resolution. With their efficiency, safety, and precision, power maintenance drones are playing an increasingly important role in the power industry, becoming a crucial tool for modernizing operations and maintenance.

[0003] Since power inspection drones have multiple inspection and maintenance functions, it is necessary to mount multiple payload devices on the drone body. Although traditional power inspection drones can mount payload devices, the installation position of the payload devices is fixed. When the number of payload devices is large or the equipment is changed, the balance of the center of gravity cannot be guaranteed, resulting in the drone being unstable during flight. In addition, the traditional installation method cannot easily adjust the installation angle and installation position of the payload devices, making it inconvenient to use. Utility Model Content

[0004] The purpose of the present invention is to provide a power maintenance UAV device in order to solve the problem of poor stability of the above-mentioned power maintenance UAV when carrying an external load. The device has the advantages of flexible installation, easy adjustment of load balance, and good flight stability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An electric power maintenance drone device includes a drone body and a load bracket, wherein the load bracket includes a telescopic bracket, a mounting bracket installed on the telescopic bracket, and an external bracket installed on the mounting bracket. The mounting bracket includes a mounting ring, the center position of the mounting ring coincides with the position of the telescopic bracket, and the mounting bracket is movably fixed to the mounting ring and can move along the outer circumference of the mounting ring.

[0007] Preferably, a plurality of the mounting brackets are provided above and below, and the diameters of the mounting rings of the mounting brackets increase successively from top to bottom.

[0008] Preferably, the external bracket includes a clamping mechanism composed of a first clamping arm and a second clamping arm, which is used to clamp and fix on the outer wall of the mounting ring, and an external mounting seat for fixing the load is also installed on the clamping mechanism.

[0009] Preferably, the first clamping arm and the second clamping arm are arranged to rotate crosswise through a rotating axis, and the first clamping arm is welded with a first connecting rod away from the clamping end, and the second clamping arm is welded with a second connecting rod away from the clamping end, the first connecting rod is welded to the external mount, and the second connecting rod is installed on the external mount through a locking bolt, and the diameter of the locking bolt is smaller than the diameter of the bolt hole on the external mount.

[0010] Preferably, the telescopic bracket includes a sleeve and a connecting rod plugged into the sleeve, a plurality of spring columns are provided on the outer wall of the connecting rod along the length direction, and a positioning hole matching the size of the spring column is provided on the sleeve.

[0011] Preferably, the external bracket further includes a fixing seat that coincides with the center position of the mounting ring, the fixing seat is fixed on the sleeve, and the mounting ring and the fixing seat are connected via a support rod.

[0012] Preferably, an electrical socket is provided on the drone body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model uses a telescopic bracket to enable the mounting bracket to move up and down, and the mounting bracket uses a mounting ring as a fixing point for the external bracket, so that the external bracket can move along the outer wall of the mounting ring. In this way, after multiple loads are fixed on the mounting ring, they can be moved to a suitable position to achieve balance, thereby increasing the stability of the drone during flight. Therefore, the load bracket not only facilitates the external installation of the load, but also ensures stability.

[0015] 2. The external bracket of the utility model is installed on the mounting ring by clamping. Therefore, the external bracket can not only move on the mounting ring, but also rotate with the mounting ring, so that the installation angle of the load can be adjusted. The above-mentioned mounting brackets are provided in multiples, and the diameter increases from top to bottom. The redundant mounting brackets can be contracted and folded by using the telescopic brackets, and the telescopic brackets can also be stretched so that the mounting bracket with the largest diameter at the bottom can support the entire drone.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 As shown, the power maintenance UAV device includes a UAV body 1 and a load bracket. The load bracket includes a telescopic bracket 3, a mounting bracket 4 installed on the telescopic bracket 3, and an external bracket 5 installed on the mounting bracket 4. The mounting bracket 4 includes a mounting ring 10. The center position of the mounting ring 10 coincides with the position of the telescopic bracket 3. The mounting bracket 4 is movably fixed on the mounting ring 10 and can move along the outer circumference of the mounting ring 10.

[0022] The load bracket is used to install load equipment, such as sensors, cameras and other equipment used during drone inspections, as well as tools used for power maintenance. The load bracket is connected to the load equipment through an external bracket 5, and the retractable function of the telescopic bracket 3 enables the installed load equipment to adjust its height, which is convenient for the installation layout of different load equipment. Since the mounting bracket 4 uses a mounting ring 10 as the fulcrum of the external bracket 5, the external bracket 5 can move on the mounting ring 10. Since the mounting ring 10 is a ring structure, the movement trajectory of the load equipment is a circular trajectory around the telescopic bracket 3. In this way, when there are a large number of load equipment, the distribution positions of different load equipment can be adjusted to achieve the effect of balancing the center of gravity of each load equipment. In this way, the drone has better stability during flight. A power socket 2 is provided on the drone body 1, and the power socket 2 is used to facilitate power connection of the load equipment.

[0023] like Figure 1 As shown, multiple mounting brackets 4 are provided vertically, with the diameter of the mounting rings 10 increasing from top to bottom. When multiple mounting brackets 4 are provided, the telescopic function of the telescopic bracket 3 allows for folding and unfolding. Since the mounting ring 10 has the largest diameter at its bottom, it can serve as a foot to support the entire drone when unfolded. When folded, the larger mounting ring 10 can surround the smaller mounting rings 10, enhancing the folding and unfolding effect.

[0024] In order to ensure more flexible installation of load equipment, such as Figure 3As shown, the external bracket 5 includes a clamping mechanism consisting of a first clamping arm 13 and a second clamping arm 14, which is used to clamp and fix on the outer wall of the mounting ring 10. The clamping mechanism is also equipped with an external mount 19 for fixing the load. The external bracket 5 is installed on the mounting ring 10 in a clamping manner, which facilitates the installation of the external bracket 5. Moreover, by adjusting the clamping force, the external bracket 5 can be fixed and shaken. When shaking, the entire external bracket 5 can rotate and move, making the installation of the load equipment more flexible.

[0025] Since the external bracket 5 adopts a clamping method, the conventional bolt structure cannot be used for locking and fixing. Figure 3 As shown, the first clamping arm 13 and the second clamping arm 14 are arranged to rotate crosswise through the rotating shaft 17, and the first clamping arm 13 is welded with the first connecting rod 15 away from the clamping end, and the second clamping arm 14 is welded with the second connecting rod 16 away from the clamping end, the first connecting rod 15 is welded on the external mount 19, and the second connecting rod 16 is installed on the external mount 19 through the locking bolt 18, and the diameter of the locking bolt 18 is smaller than the aperture of the bolt hole on the external mount 19. Since the first connecting rod 15 is welded on the external mount 19, the movement of the second connecting rod 16 can adjust the clamping force between the first clamping arm 13 and the second clamping arm 14. Since the first clamping arm 13 and the second clamping arm 14 are cross-installed, during the rotation process, the second connecting rod 16 needs not only longitudinal displacement but also lateral movement. Here, the bolt hole of the locking bolt 18 is set to have a diameter larger than the diameter of the locking bolt 18, providing sufficient redundant space for the second connecting rod 16 to move.

[0026] like Figure 1 As shown, the telescopic bracket 3 includes a sleeve 6 and a connecting rod 7 connected to the sleeve 6. A plurality of spring columns 8 are arranged on the outer wall of the connecting rod 7 along the length direction. A positioning hole 9 matching the size of the spring column 8 is provided on the sleeve 6. The spring column 8 is inserted into the positioning hole 9 to fix the length of the connecting rod 7 inserted into the sleeve 6 to achieve a telescopic effect. The external bracket 5 also includes a fixing seat 12 coinciding with the center position of the mounting ring 10. The fixing seat 12 is fixed on the sleeve 6, and the mounting ring 10 and the fixing seat 12 are connected by a support rod 11.
