Description

Technical Field

[0001] This utility model relates to the field of power station inspection technology, specifically an inspection drone for power transmission and transformation station inspection. Background Technology

[0002] Ground equipment in power transmission and transformation stations is generally inspected using ground mobile inspection robots, while equipment and lines in the air are generally inspected using inspection drones.

[0003] The current inspection drones are similar to those disclosed in CN218022167U. The quadcopter drone used for inspection consists of the drone body and an inspection camera. As can be seen from this technical solution, the existing technology lacks protection for the inspection camera. In the event of an unavoidable crash caused by an accidental collision, the inspection camera will most likely be damaged. Because inspection cameras have many functions and complex structures, they are generally expensive. Therefore, the existing technology cannot protect the inspection camera in the event of a crash, thus failing to reduce losses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inspection drone for power transmission and substation inspection, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an inspection drone for substation inspection, comprising a drone body, wherein buffer components are provided around the bottom of the drone body, and fixing rods are provided on each buffer component;

[0006] The bottom of the drone body is provided with a fixing component, which is used to fix the surrounding fixing rods.

[0007] All the surrounding fixing rods are connected to the mounting plate. The bottom of the mounting plate is provided with a rotating seat 1. The rotating seat 1 is provided with a mounting frame. The mounting frame is provided with two rotating seats 2. The two rotating seats 2 are respectively connected to the camera and the infrared thermal imager.

[0008] The fixed rods on both the left and right sides are connected to rotating components, and the rotating components are equipped with protective covers. The protective covers are located on both sides of the mounting frame.

[0009] Preferably, the rotating assembly includes two connecting rods, which are respectively connected to two fixed rods at the front and rear. A rotating shaft is connected between the two connecting rods via a bearing. A reduction motor connected to the rotating shaft is provided on the front connecting rod, and the protective cover is connected to the rotating shaft.

[0010] Preferably, a buffer sleeve is provided on the outer side of the protective cover.

[0011] Preferably, the buffer assembly includes a vertical rod disposed on the drone body, the vertical rod being slidably connected to a fixed rod, and a buffer spring connected to the vertical rod being disposed inside the fixed rod.

[0012] Preferably, the fixing component includes a bidirectional electric guide rail mounted on the UAV body, with plugs provided at both output ends of the bidirectional electric guide rail, and the two plugs on opposite sides being inserted into the surrounding fixing rods.

[0013] Preferably, the bidirectional electric guide rail and the insertion rod are both located above the mounting plate.

[0014] This invention provides an inspection drone for power transmission and substation inspection. Compared with the prior art, it has the following advantages:

[0015] 1. When the inspection drone used for substation inspection is hit by a collision and crashes, the control rotating component drives the protective cover to rotate, so that the protective covers on both sides cover the camera and infrared thermal imager to protect them. This prevents the camera and infrared thermal imager from directly hitting the ground and causing damage, thus reducing losses in the event of a crash.

[0016] 2. The inspection drone used for substation inspection has a buffer sleeve on the outside of the protective cover, which can buffer and protect the protective cover, reduce the probability of damage to the protective cover, and thus better protect the internal camera and infrared thermal imager.

[0017] 3. This inspection drone used for substation inspections features a buffer sleeve that initially cushions the protective cover. After the impact force acts on the fixed rod, it is further cushioned by the buffer assembly, thereby improving the buffering capacity of the protective cover and further reducing the probability of damage to the protective cover. This better protects the internal camera and infrared thermal imager. The mounting plates for the camera and infrared thermal imager are also fixed to the fixed rod, rather than to the drone body. This prevents the impact on the drone body during a crash from directly hitting the camera and infrared thermal imager, protecting them. When the buffer assembly is not in use, the fixed rod is fixed in place by the fixing assembly, preventing the camera and infrared thermal imager from shaking due to the buffer assembly, thus ensuring the stability of the images and results during inspections.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First implementation: An inspection drone for substation inspection, including drone body 1, with buffer components provided around the bottom of drone body 1, and fixed rods 2 provided on each buffer component.

[0026] The bottom of the drone body 1 is equipped with a fixing component, which is used to fix the fixing rods 2 around the perimeter.

[0027] All four fixed rods 2 are connected to the mounting plate 3. The bottom of the mounting plate 3 is provided with a rotating seat 4, and a mounting frame 5 is provided on the rotating seat 4. Two rotating seats 6 are provided on the mounting frame 5, and the two rotating seats 6 are respectively connected to the camera 7 and the infrared thermal imager 8. Through the rotating seats 4 and the rotating seats 6, the camera 7 and the infrared thermal imager 8 can be adjusted up and down and rotated 360 degrees, so that all-round inspection can be carried out. Of course, the UAV body 1 is provided with other inspection structures that are required in the existing technology, such as a millimeter-wave radar array, which is used to penetrate vegetation and light obstructions to accurately measure the sag of the conductor and the offset of the insulator string, and also a soundprint acquisition system, which identifies abnormal vibration noise of the equipment through spectrum analysis and locates the source of mechanical failure.

[0028] Mounting plate 3 is connected to fixing rod 2, and fixing rod 2 is connected to drone body 1 through buffer assembly. The fixing assembly can also fix fixing rod 2, so that fixing rod 2 and mounting plate 3 will not shake during daily use, ensuring the stability of camera 7 and infrared thermal imager 8 during use. Since mounting plate 3 is not fixed to drone body 1, the fixing of fixing rod 2 can be removed in the event of a crash, so that the impact on drone body 1 during a crash will not directly impact camera 7 and infrared thermal imager 8, thus protecting camera 7 and infrared thermal imager 8.

[0029] The left and right fixed rods 2 are connected to rotating components, and the rotating components are equipped with protective covers 9. The protective covers 9 are located on both sides of the mounting frame 5, and the rotating components are used to drive the protective covers 9 to rotate.

[0030] The rotating assembly includes two connecting rods 10, which are respectively connected to the front and rear fixed rods 2. A rotating shaft 11 is connected between the two connecting rods 10 through a bearing. A reduction motor 12 connected to the rotating shaft 11 is provided on the front connecting rod 10. The protective cover 9 is connected to the rotating shaft 11. The rotating shaft 11 is driven to rotate by the reduction motor 12, so that the protective cover 9 can rotate.

[0031] A rubber buffer sleeve 13 is provided on the outside of the protective cover 9 to cushion and protect the protective cover 9, reduce the probability of the protective cover 9 being damaged, and thus better protect the internal camera 7 and infrared thermal imager 8. Small ventilation holes can be evenly arranged on the protective cover 9 and the buffer sleeve 13, so that the protection of the camera 7 and infrared thermal imager 8 is not affected, and drag is reduced during daily flight.

[0032] The buffer assembly includes a vertical rod 14 mounted on the drone body 1. The vertical rod 14 is slidably connected to a fixed rod 2, and a buffer spring 15 connected to the vertical rod 14 is provided inside the fixed rod 2. When the protective cover 9 applies a pushing force to the fixed rod 2 through the connecting rod 10, it slides on the vertical rod 14 and is buffered by the buffer spring 15.

[0033] The fixing component includes a bidirectional electric guide rail 16 mounted on the UAV body 1. Both output ends of the bidirectional electric guide rail 16 are provided with insertion rods 17. The two sides of the insertion rods 17 that are far apart from each other are respectively inserted into the surrounding fixing rods 2. The bidirectional electric guide rail 16 drives the two sides of the insertion rods 17 to move in opposite directions, so that they can be inserted into or move away from the surrounding fixing rods 2 respectively.

[0034] The second implementation differs from the first implementation in that the bidirectional electric guide rail 16 and the insertion rod 17 are both located above the mounting plate 3, so that the mounting plate 3 is not obstructed when it follows the fixing rod 2 for buffering.

[0035] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0036] In use, when the drone body 1 is accidentally hit and crashes, the ground station personnel remotely control the reduction motor 12 to work, causing the two protective covers 9 to rotate until they make contact with each other, protecting the camera 7 and the infrared thermal imager 8. Then, the bidirectional electric guide rail 16 is controlled to drive the insertion rod 17 away from the fixed rod 2. When the protective cover 9 touches the ground, it is first buffered by the external buffer sleeve 13, and then the protective cover 9 acts on the fixed rod 2 through the connecting rod 10. The impact force is further buffered by the buffer spring 15 to reduce the probability of the protective cover 9 breaking and opening, thereby better protecting the internal camera 7 and infrared thermal imager 8.
