DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0017] In view of the problems existing in the prior art, an embodiment of the present invention provides a hovering device for a power grid material storage drone inspection system, comprising a drone 1 and a shelf 2, and a hovering mechanism 3, wherein the hovering mechanism 3 can hover the drone 1 on the shelf 2, and the hovering mechanism 3 comprises a first hovering part arranged on the drone 1, and a second hovering part arranged on the shelf 2, wherein the first hovering part and the second hovering part are matched and docked to realize the hovering of the drone 1 relative to the shelf 2, wherein the number of the hovering mechanisms 3 is N, and N is a positive integer greater than or equal to 1. In the present invention, a first hovering part and a second hovering part are arranged on the drone 1 and the shelf 2, and the hovering of the drone 1 relative to the shelf 2 is realized by matching and docking the first hovering part and the second hovering part, so that when a certain place is inspected regularly, the drone can be hovered, and the drone does not need to work continuously, thereby avoiding waste of resources; and the arrangement of the combined structure of the first hovering part and the second hovering part can add a parking space for the drone 1 on the shelf 2, thereby making it more convenient to park the drone 1.

[0018] In the actual working process, when the drone is conducting an inspection, it is necessary to hover and inspect a certain position for a certain period of time. In the current technology, since there is no short-term hovering structure on the shelf or the drone, the drone needs to work all the time and be suspended in the air in a flying state. This state will not only lead to the rapid consumption of the drone battery power, but also the drone's suspended flight will cause the drone to shake with the inspection equipment (such as a camera) due to the flow of air, which will lead to inaccurate inspection results. The hovering mechanism 3 set in the present invention can make the drone 1 not need to be in a working state all the time through the drone hovering on the shelf 2, and at the same time, it can avoid the shaking of the inspection equipment when hovering, so that the inspection results are more accurate.

[0019] In one embodiment, the first hovering part includes a rectangular column 31 fixedly connected to the drone 1, and a truncated cone guide rod 32 is fixedly connected to the end of the rectangular column 31 away from the drone 1; the second hovering part includes a fixed column 34 fixedly arranged on the side wall of the shelf 2, and a rectangular groove 36 and a speaker groove 35 are provided on the fixed column 34, and a speaker tube 33 is fixedly arranged on the side of the fixed column 34 away from the shelf 2. The structural design of the hovering mechanism 3 in the present invention is reasonable. After the combination structure of the rectangular column 31 and the truncated cone guide rod 32 is inserted into the speaker groove 35 and the rectangular groove 36, the combination structure of the rectangular column 31 and the truncated cone guide rod 32 can be supported by the rectangular groove 36, so that the drone 1 can hover relative to the shelf 2; the present invention also provides a combination structure of the truncated cone guide rod 32, the speaker tube 33 and the speaker groove 35, which can make the rectangular column 31 smoothly enter the rectangular groove 36.

[0020] In one embodiment, the trumpet tube 33, the trumpet groove 35 and the rectangular groove 36 are arranged in communication, and the trumpet groove 35 is arranged between the trumpet tube 33 and the rectangular groove 36; the opening size of the end of the trumpet tube 33 away from the fixed column 34 is larger than the opening size of the end close to the fixed column 34; the size of the end of the truncated cone guide rod 32 away from the rectangular column 31 is smaller than the size of the end close to the rectangular column 31.

[0021] During the actual hovering process, since the flight altitude of the drone 1 is mostly manually controlled, there is a problem that the horizontal center line of the rectangular column 31 is not on the same horizontal line as the horizontal center line of the fixed column 34, which makes it impossible for the rectangular column 31 to enter the rectangular groove 36.

[0022] In order to solve the above problem, in one embodiment, a moving mechanism 4 is further included, wherein the moving mechanism 4 includes a moving slider 41 connected to the fixed column 34, the moving slider 41 is slidably arranged in a moving slide 42, the moving slide 42 is opened on the shelf 2, and one end of a first guiding telescopic component 43 is fixedly connected to the lower end surface of the moving slider 41, and the other end of the first guiding telescopic component 43 is fixedly connected to the bottom wall of the moving slide 42. In the present invention, the moving mechanism 4 is provided, so that the rectangular column 31 can be further allowed to enter the rectangular groove 36 through the movement of the fixed column 34. Specifically, when the horizontal midlines of the rectangular column 31 and the rectangular groove 36 are not on the same horizontal line, as the combined structure of the rectangular column 31 and the truncated cone guide rod 32 moves to the right, it will interfere with the horn tube 33 and the fixed column 34 to move upward or downward, so that through the movement of the fixed column 34, the horizontal midlines of the rectangular column 31 and the rectangular groove 36 are moved to the same horizontal line, so that the rectangular column 31 can smoothly enter the rectangular groove 36.

[0023] During operation, when the horizontal center line of the rectangular column 31 is not on the same horizontal line as the horizontal center line of the fixed column 34, as the rectangular column 31 moves to the right, it will push the fixed column 34 to move upward or downward. The upward or downward movement of the fixed column 34 will cause the movable slider 41 to move up and down in the movable slide groove 42. Through the above movement, the horizontal center line of the rectangular column 31 and the horizontal center line of the fixed column 34 can be moved to the same horizontal line, so that the rectangular column 31 can smoothly enter the rectangular groove 36.

[0024] In one embodiment, the first guide telescopic assembly 43 includes a first guide telescopic rod 431, a first guide telescopic tube 432 and a first guide telescopic spring 433, the first guide telescopic rod 431 is movably inserted in the first guide telescopic tube 432, the first guide telescopic spring 433 is wound and arranged outside the first guide telescopic rod 431, and the two ends of the first guide telescopic spring 433 are respectively fixedly connected to the side wall of the first guide telescopic rod 431 and the outer side wall of the first guide telescopic tube 432.

The positioning mechanism 5 provided in the present invention is used to achieve the locking of the fixed column 34. Specifically, after the horizontal midlines of the rectangular column 31 and the rectangular groove 36 move to the same horizontal line through the movement of the fixed column 34, the rectangular column 31 moves to the right and enters the rectangular groove 36, which will resist the rightward movement of the moving block 51. The rightward movement of the moving block 51 will push the locking rod 53 into one of the locking grooves 55, thereby locking the current position of the fixed column 34.

[0026] In one embodiment, the number of the locking grooves 55 is M, where M is a positive integer greater than 1, and the locking grooves 55 are vertically distributed on the same straight line, and the locking grooves 55 are equidistantly distributed, wherein there is a gap between two adjacent locking grooves 55, and the distance of the gap is less than 0.5 mm. This arrangement allows the locking rod 53 to smoothly enter the locking groove 55.

[0028] Due to the flying angle of the drone 1 , in one case, the rectangular column 31 may tilt and enter the rectangular groove 36 , which may cause the drone 1 to tilt.

[0029] In order to make the drone 1 always in a horizontal state, in one embodiment, it also includes a balancing support mechanism 6, which includes two vertical connecting rods 61 fixedly connected to the opposite ends of the moving block 51, and the vertical connecting rod 61 is movably arranged in a second moving through hole 62, and the second moving through hole 62 is opened on the fixed column 34. The side wall of the vertical connecting rod 61 is fixedly connected to one end of a traction conveyor belt 63, and the other end of the traction conveyor belt 63 is wound around the outside of a fixed turntable 64, and the fixed turntable 64 is fixedly sleeved on the outside of an inner spiral tube 65, and the lower end of the inner spiral tube 65 is fixedly connected to a rotating shaft 66, and the rotating shaft 66 is rotatably arranged on the fixed column 34.
