[0004] With regard to the above-mentioned related technologies, when the existing transmission line drone inspection equipment is inspecting the transmission line, if the transmission line is frozen, it uses a knocking rod to knock on the transmission line, but the drone is affected by the ambient airflow and it is difficult to maintain stable flight. In addition, the transmission line is affected by its own gravity and droops in a curved shape between the two transmission towers. When the drone flies along the transmission line to de-ice the transmission line, it is also necessary to adjust the flight altitude in real time, which places high technical requirements on the operator. In summary, the existing transmission line drone inspection equipment is not easy to stably de-ice the frozen transmission line. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a transmission line drone inspection equipment to solve the technical problem that the existing transmission line drone inspection equipment is not easy to stably de-ice the frozen transmission lines.

[0012] The utility model is further configured such that the sum of the lengths of the telescopic tube and the fixed tube is greater than the length of the knocking rod.

[0013] By adopting the above technical solution, it is prevented that the knocking rod hits the machine body when rotating.

[0014] The utility model is further configured such that the knocking rods at the front and rear ends below the machine body rotate in opposite directions.

[0015] By adopting the above technical solution, the hook can be hooked onto the power transmission line more stably.

[0018] The utility model is further configured such that the axis of the hanging rod is orthogonal to the flight direction of the UAV.

[0019] By adopting the above technical solution, the hanging rod can be rotated and folded when the UAV lands.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] The utility model arranges a hook structure under the body of the UAV, and rotatably arranges a knocking rod structure at the front and rear ends of the hook structure respectively, and uses the hook to hook the power transmission line, so that the UAV maintains a tendency to fly obliquely upward and moves along the direction of the power transmission line.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] Embodiment 1

[0030] A transmission line drone inspection device, such as Figure 1-4As shown, it includes a body 1, a hanging rod 8 is connected to the bottom end of the body 1, a hook 9 is arranged at the bottom end of the hanging rod 8, an opening wider than the diameter of the power transmission line is arranged on one side of the hook 9, so that the power transmission line can be smoothly inserted into the hook 9, and can be freely and quickly detached when the UAV wants to detach from the power transmission line, and the bottom end of the body 1 is also connected to a driving motor 4 facing the front and rear ends respectively, and the output end of the driving motor 4 is fixedly connected to a rotating block 5, and both ends of the rotating block 5 are rotatably connected to a knocking rod 6, when the knocking rod 6 is perpendicular to the ground, its bottom end is lower than the hook 9, and the knocking rod 6 at the front and rear ends below the body 1 rotate in opposite directions, so that the power transmission line can be kept as balanced as possible when being knocked by the knocking rod 6, to prevent the power transmission line from shaking violently, and at the same time, the hook 9 can also hook the power transmission line more stably.

[0031] See also Figure 1-3 The two drive motors 4 connected to the bottom of the body 1 are coaxially arranged. When the two drive motors 4 work at the same time, since the rotating shafts of the two are on the same axis, the stability of the bottom of the drone can be effectively improved when the knocking rod 6 knocks the power line. The axis of the hanging rod 8 is orthogonal to the flight direction of the drone, so that the hanging rod 8 can be rotated and folded when the drone lands.

[0032] Embodiment 2

[0033] A transmission line drone inspection device, such as Figure 1-4 As shown, on the basis of embodiment 1, the difference from embodiment 1 is that the bottom end of the body 1 is fixedly connected with a fixed cylinder 2, and the bottom end of the fixed cylinder 2 is slidably connected with a telescopic cylinder 3. Specifically, in order to reduce the take-off weight of the UAV, the fixed cylinder 2 and the telescopic cylinder 3 are both hollow structures, and the bottom end of the telescopic cylinder 3 is fixedly connected with a fixed block 7, and the bottom end of the fixed block 7 is rotatably connected to a hanging rod 8. When the UAV lands, the telescopic cylinder 3 shrinks in the fixed cylinder 2, and the hanging rod 8 rotates toward a state parallel to the ground. At this time, the landing gear of the UAV can land stably on the ground, avoiding the fixed cylinder 2 and the telescopic cylinder 3 and other mechanisms from affecting the normal take-off and landing of the UAV.

[0034] See also Figure 1-3 When the telescopic cylinder 3 is retracted into the fixed cylinder 2, the height of the fixed block 7 is higher than the landing gear of the UAV. Specifically, since the hanging rod 8 can be rotatably connected to the fixed block 7, when the UAV lands, the hook 9 at the bottom of the hanging rod 8 first touches the ground, and then rotates around the rotating shaft at the fixed block 7, tending to be parallel to the ground, so that the UAV can easily achieve stable landing. After the telescopic cylinder 3 is retracted into the fixed cylinder 2, the fixed block 7 at the bottom of the fixed cylinder 2 is higher than the bottom surface of the landing gear, thereby achieving a smooth take-off and landing of the UAV. The sum of the lengths of the telescopic cylinder 3 and the fixed cylinder 2 is greater than the length of the knocking rod 6, which prevents the knocking rod 6 from hitting the body 1 when it rotates.

[0035] The working principle of the utility model is as follows: when the UAV takes off, the telescopic cylinder 3 slides out of the fixed cylinder 2 due to its own gravity. When the telescopic cylinder 3 slides out to the maximum stroke, the hanging rod 8 gradually leaves the ground until it remains perpendicular to the ground. The UAV flies to inspect the transmission line. When an iced transmission line is found, it flies above the transmission line, and after hooking the transmission line with the hook 9, the UAV is controlled to keep flying obliquely upward away from the opening direction of the hook 9, so that the hanging rod 8 tightens the transmission line. At the same time, the two sets of drive motors 4 are started, and the knocking rod 6 is swung by the centrifugal force. When it hits the transmission line, it will rotate around the rotating shaft between the rotating block 5 and the knocking rod 6, so that the knocking rod 6 can maintain a continuous rotation state and continuously knock on the transmission line in the rotating state, thereby achieving a stable deicing effect on the transmission line.

[0036] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
