[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. It has the advantages of small size, low cost, and easy use. In order to make drones better adapt to outdoor operations and improve the endurance of drones, the use of drone nests can, on the one hand, store drones in the nests in bad weather, which plays a protective role for the drones and helps to extend the service life of the drones; on the other hand, the drones can also be charged through the nests to complete outdoor charging of the drones, thereby improving the endurance of drones when working outdoors for a long time. Drones play an important role in the operation and maintenance of overhead power lines of power grids. Drones can conduct all-round and no-dead-angle inspections without directly contacting wires, which can reduce the risk of accidents for workers when working at high altitudes.

[0003] Existing drone nests are fixedly installed outdoors. Since drone nests are usually provided with an openable cover to facilitate the drone to fly out of the nest, and the weather in the outdoor environment is changeable, if there is heavy rain, raindrops can easily enter the nest through the gaps in the nest, which can easily cause damage to the electrical components inside the nest. Therefore, a fixed nest for overhead line operation and maintenance of power grids suitable for multiple models is proposed to solve the above problems. Utility Model Content

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1-4 In this embodiment, a fixed nest suitable for operation and maintenance of overhead power lines of a power grid of multiple models includes a drone nest 1, a fixed base 2 is fixedly installed at the bottom of the drone nest 1, and a rainproof mechanism is arranged on the fixed base 2.

[0024] Among them, the charging method of the drone nest 1 is contact charging, which requires the drone to land accurately on the charging platform in the nest and charge through physical connection. This charging platform is compatible with drones of different sizes and brands, and even existing models can be used after simple modification, and is suitable for use with multiple models.

[0025] The rainproof mechanism includes a dual-axis motor 11 and a rainproof top cover 6. The dual-axis motor 11 is fixedly installed on the inner bottom wall of the fixed base 2. The output shafts on the left and right sides of the dual-axis motor 11 are fixedly connected with rotating rods. The side of the rotating rod away from the dual-axis motor 11 is fixedly connected with a driving bevel gear 12. The left and right sides of the top of the fixed base 2 are rotatably connected with a rotating cylinder 4. The internal thread of the rotating cylinder 4 is connected with a threaded rod 5. The outside of the rotating cylinder 4 is fixedly installed with a driven bevel gear 10. The driving bevel gear 12 is meshed with the driven bevel gear 10. The top of the threaded rod 5 passes through the rotating cylinder 4 and is fixedly connected to the inner top wall of the rainproof top cover 6. A sliding rod 7 is fixedly installed at the center of the inner top wall of the rainproof top cover 6, and the bottom of the sliding rod 7 is fixedly connected with a limiting slider 8.

[0026] It can be understood that the slide rod 7 plays a guiding role for the rainproof top cover 6. Under the limiting effect of the sliding connection between the slide rod 7 and the fixed cylinder 9, when the two rotating cylinders 4 rotate synchronously, the two threaded rods 5 can move out of or into the rotating cylinder 4, thereby realizing the adjustment of the height of the rainproof top cover 6.

[0027] See also Figure 1 and Figure 2 A fixed cylinder 9 is fixedly installed on the top of the fixed base 2, the bottom of the slide rod 7 passes through the fixed cylinder 9 and extends to the inside, the limit slider 8 is slidably connected to the inside of the fixed cylinder 9, the interior of the fixed base 2 is a cavity structure, and a maintenance door 14 is detachably installed on the front surface of the fixed base 2.

[0028] It should be noted that the inspection door 14 is fixed to the fixed base 2 by bolts, and a sealing gasket is provided between the inspection door 14 and the fixed base 2 .

[0029] It should be noted that when it rains, by setting a rainproof top cover 6 above the drone nest 1, it can play a rainproof effect. If the rain is heavy, the two active bevel gears 12 can be driven to rotate by the dual-axis motor 11, so that the driven bevel gear 10 can be rotated to drive the rotating cylinder 4 to rotate, so that the threaded rod 5 moves into the rotating cylinder 4, and the rainproof top cover 6 can be lowered, shortening the distance between the rainproof top cover 6 and the drone nest 1, and achieving a better rainproof effect.

[0030] See also Figure 2 A fixed plate 13 is fixedly installed on both the left and right sides of the fixed base 2, and the rotating rod is rotatably connected to the inside of the fixed plate 13 through a bearing. Two protective covers 3 are fixedly installed on the top of the fixed base 2. The two protective covers 3 are respectively located outside the two rotating cylinders 4. The top of the rotating cylinder 4 passes through the protective covers 3 and extends to the outside. A rotating block 15 is fixedly connected to the bottom of the rotating cylinder 4, and the rotating block 15 is rotatably connected to a movable groove opened on the top of the fixed base 2.

[0031] By providing the fixing plate 13, the fixing plate 13 can rotate more stably, and the rotating cylinder 4 can be restricted by the rotating block 15, while the rotating cylinder 4 can be rotated.

[0032] The working principle of the above embodiment is as follows: during use, if it rains, the rainproof top cover 6 is blocked above the drone nest 1, which can play a rainproof effect. If the rain is heavy, the dual-axis motor 11 is controlled by an external control device to drive the two active bevel gears 12 to rotate, so that the driven bevel gear 10 can be rotated to drive the rotating cylinder 4 to rotate. Under the limiting effect of the sliding connection between the slide rod 7 and the fixed cylinder 9, the threaded rod 5 is moved into the rotating cylinder 4, so that the rainproof top cover 6 can be lowered, shortening the distance between the rainproof top cover 6 and the drone nest 1, thereby achieving a better rainproof effect. If the drone needs to fly out of the drone nest 1, the dual-axis motor 11 is reversed to raise the rainproof top cover 6, thereby facilitating the adjustment of the distance between the rainproof top cover 6 and the drone nest 1, so that drones of different specifications can fly out of the gap between the drone nest 1 and the rainproof top cover 6.

[0033] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0034] The fixed nest for maintenance of overhead power line of power grids, which is applicable to multiple models of machines, can protect against rain by setting a rainproof top cover above the nest of unmanned aerial vehicles (UAVs). If the rain is heavy, the two active bevel gears can be rotated by a double-axis motor, so that the driven bevel gears can rotate and drive the rotating cylinder to rotate, so that the threaded rod can be moved into the rotating cylinder, and the rainproof top cover can be lowered, shortening the distance between the rainproof top cover and the nest of the UAV, thereby achieving a better rainproof effect.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
