[0031] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 6As shown, a power inspection drone provided by the present invention is used to inspect overhead cables 8. The power inspection drone includes a fuselage 1, wings 3, a locking device 4, a trigger device 5 and a reset device 6. Among them, the fuselage 1 is the main part of the power inspection drone, and the fuselage 1 includes a drone body and a support leg 11 arranged at the bottom of the drone body, and the support leg 11 is used for parking on the ground. The drone body includes a power supply unit, a control unit, a detection unit and a communication unit. The power supply unit is used to provide electric energy, the control unit is used for flight control, detection control and communication information processing, etc., the detection unit is used to detect the overhead cables 8, and the communication unit is used to communicate wirelessly with the ground flight control system. The wing 3 is electrically connected to the power supply unit and the control unit, and the wing 3 is used to provide flight power. There are four wings 3, and the four wings 3 are distributed at the four corners of the fuselage 1. Connectors 2 are respectively arranged at the four corners of the fuselage 1, and the free ends of the connectors 2 extend in a direction away from the fuselage 1, and the four wings 3 are respectively rotated and arranged at the free ends of the four connectors 2. In this embodiment, the connecting member 2 extends in the horizontal direction, and the wing 3 is installed at the free end of the connecting member 2, so that the wing 3 is spaced from the fuselage 1 to provide enough space for the wing 3. The wing 3 is rotatably connected to the connecting member 2 so that the wing 3 can rotate around the connection point between the wing 3 and the connecting member 2. The locking device 4 is used to fix the wing 3. The wing 3 and the connecting member 2 are both connected to the locking device 4. The locking device 4 has a locked state and an unlocked state. In the locked state, the wing 3 is fixed on the connecting member 2 in the vertical direction, that is, the wing 3 is perpendicular to the connecting member 2. In this state, the power inspection drone can fly normally. In the unlocked state, the wing 3 can rotate in a direction away from the fuselage 1, so that the angle between the wing 3 and the connecting member 2 increases, and moves from the vertical state of the wing 3 and the connecting member 2 to the parallel state or the state close to the parallel state of the wing 3 and the connecting member 2. The trigger device 5 is movably arranged on the wing 3. When the trigger device 5 is squeezed by an external force, the trigger device 5 drives the locking device 4 to unlock. The reset device 6 is arranged between the wing 3 and the connecting member 2 , and is used to drive the wing 3 to move to a locked state, that is, the reset device 6 drives the wing 3 to move to a position perpendicular to the connecting member 2 , and enables the locking device 4 to lock the wing 3 .

[0033] It is understandable that in order for the electric power inspection drone to maintain a normal flight state, the wing 3 needs to be perpendicular to the connector 2, and the wing 3 can be vertically fixed to the connector 2 by the locking device 4. When one of the wings 3 is hung on the overhead cable 8 during flight, the wing 3 loses its flight power, and the fuselage 1 moves downward under the weight. At this time, the fulcrum of the entire electric power inspection drone is located on the hung wing 3. The trigger device 5 is subjected to the squeezing force from the overhead cable 8 and drives the locking device 4 to unlock. After the locking device 4 is unlocked, the wing 3 rotates around its connection with the connector 2 in a direction away from the fuselage 1, so that the wing 3 and the connector 2 tend to be parallel. During the rotation of the wing 3, the overhead cable 8 slides along the length direction of the wing 3 until the overhead cable 8 is separated from the wing 3, so as to realize the automatic escape of the electric power inspection drone. After the wing 3 is separated from the overhead cable 8, the reset device 6 drives the wing 3 to move back to a position perpendicular to the connector 2, and restores the locking device 4 to a locked state, so that the electric power inspection drone can continue to fly.

[0034] Specifically, refer to Figure 2 , Figure 5 and Figure 6 As shown, the wing 3 includes a fixing column 31 and a blade assembly 32. The bottom of the fixing column 31 is mounted on the connecting member 2, and the blade assembly 32 is mounted on the top of the fixing column 31. The blade assembly 32 includes a plurality of blades, and the flight power is generated by the rotation of the blade assembly 32. A first mounting hole 21 is provided at the top of the connecting member 2. The first mounting hole 21 is connected to the free end of the connecting member 2, that is, the first mounting hole 21 is located at the end of the connecting member 2 away from the fuselage 1. The first mounting hole 21 runs through the upper and lower sides of the connecting member 2. A first connection point 311 is provided at the end of the fixing column 31 away from the blade assembly 32, and the fixing column 31 is rotatably connected to the hole wall of the first mounting hole 21 through the first connection point 311. Specifically, the first connection point 311 is a connection hole opened on the fixing column 31, and a connection shaft is rotatably provided in the connection hole, and one end of the connection shaft is fixed to the hole wall of the first mounting hole 21, so that the fixing column 31 and the connecting member 2 can be rotatably connected.

[0035] The reset device 6 includes a first spring 61, a movable block 62 and a connecting plate 63. A first mounting groove 22 is provided on the hole wall of the first mounting hole 21 on the side facing the fuselage 1, the notch of the first mounting groove 22 is connected to the first mounting hole 21, and the groove wall of the first mounting groove 22 on the side facing the top of the connecting member 2 is connected to the outside of the connecting member 2. The movable block 62 is installed in the first mounting groove 22, and the movable block 62 can slide along the length direction of the first mounting groove 22 to achieve a sliding connection between the movable block 62 and the connecting member 2. The two ends of the first spring 61 are respectively connected to the movable block 62 and the bottom of the first mounting groove 22, so that the movable block 62 is elastically connected to the connecting member 2 through the first spring 61. A second mounting groove 314 is provided on the end of the fixed column 31 away from the blade assembly 32, and the side of the fixed column 31 facing the fuselage 1 and the side away from the fuselage 1 are both connected to the second mounting groove 314. The first connection point 311 is located on the groove wall of the second mounting groove 314, and the first connection point 311 is located at one end of the second mounting groove 314 close to the groove. A second connection point 312 is provided at the groove bottom of the second mounting groove 314, that is, the second connection point 312 is located between the first connection point 311 and the blade assembly 32. One end of the connecting plate 63 is hinged to the movable block 62, and the other end is hinged to the second connection point 312. When the wing 3 rotates in the direction away from the fuselage 1, the wing 3 rotates around the first connection point 311, and drives the movable block 62 to slide in the direction away from the fuselage 1 through the second connection point 312, and at the same time drives the first spring 61 to extend. When the overhead cable 8 is detached, the first spring 61 drives the movable block 62 to slide in the opposite direction close to the fuselage 1, and pulls the fixed column 31 to rotate back to the vertical direction through the connecting plate 63, so that the wing 3 is perpendicular to the connecting member 2.

[0036] In order to prevent the wing 3 from being subjected to excessive movement impact when restoring the locked state, the reset device 6 also includes a buffer 64, which is arranged on the fixed column 31 and is used to mitigate the movement impact between the fixed column 31 and the connecting member 2. In this embodiment, the buffer 64 is arranged on the hole wall of the first mounting hole 21, and the buffer 64 is located on the side of the fixed column 31 away from the fuselage 1. When the wing 3 is in a vertical direction (i.e., locked state), the buffer 64 abuts against the fixed column 31. When the reset device 6 drives the wing 3 to rotate from the direction away from the fuselage 1 to the direction close to the fuselage 1, the end of the fixed column 31 away from the blade assembly 32 can elastically abut against the buffer 64 to mitigate the impact. The buffer 64 is made of elastic material, such as rubber, cork, etc. To further enhance the buffering effect, a fifth mounting hole 315 is provided on the side of the fixing column 31 facing away from the fuselage 1. A spring piece 316 is provided in the fifth mounting hole 315. The spring piece 316 is elastic. Part of the spring piece 316 extends outside the fifth mounting hole 315. When the wing 3 rotates to a vertical direction, the spring piece 316 abuts against the buffer member 64, and the kinetic energy of the wing 3 is absorbed through the elastic deformation of the spring piece 316.

[0037] Specifically, refer to Figures 2 to 6 As shown, the locking device 4 includes a guide plate 41, a locking rod 43, a telescopic rod 44 and a second spring 42. The locking device 4 is used to fix the wing 3 on the connecting member 2. There are two locking devices 4, and the two locking devices 4 are distributed on opposite sides of the wing 3. The locking rods 43 in the two locking devices 4 are integrally formed, and it can also be understood that the two locking devices 4 share one locking rod 43. A second mounting hole 313 is provided on the fixing column 31. The second mounting hole 313 is a long hole. The second mounting hole 313 extends along the length direction of the fixing column 31, and the second mounting hole 313 passes through the opposite sides of the fixing column 31. The locking rod 43 is penetrated in the second mounting hole 313, and the locking rod 43 can move along the length direction of the second mounting hole 313, and both ends of the locking rod 43 extend to the outside of the second mounting hole 313. A mounting plate is protruding from the side of the fixing column 31, and the mounting plate is located at one end close to the blade assembly 32. The telescopic rod 44 is telescopic, and the two ends of the telescopic rod 44 are respectively connected to the ends of the mounting plate and the locking rod 43. The second spring 42 is sleeved on the telescopic rod 44, and the two ends of the second spring 42 are connected to the ends of the mounting plate and the locking rod 43. The guide plate 41 is fixedly mounted on the connecting member 2. The guide plate 41 is provided with an arc surface, and the arc surface is located on the side of the guide plate 41 away from the fuselage 1, and the arc surface extends from the bottom to the top of the guide plate 41. A groove is provided on the arc surface located at the top of the guide plate 41, and the notch of the groove faces upward. In the locked state, the two ends of the locking rod 43 are respectively inserted into the grooves on the two guide plates 41, and the second spring 42 is in a compressed state. Under the elastic force of the second spring 42, the locking rod 43 is pressed in the groove to achieve the connection and fixation between the wing 3 and the connecting member 2.

[0038] The trigger device 5 includes a push plate 51 and a pressure plate 52. The pressure plate 52 is arranged on a side of the fixed column 31 facing the fuselage 1, and one end of the pressure plate 52 is hinged to the top of the fixed column 31 so that the pressure plate 52 can rotate freely around its top. A third mounting hole 411 is provided on the guide plate 41, and the third mounting hole 411 passes through the side of the guide plate 41 facing the fuselage 1 and the side away from the fuselage 1. The third mounting hole 411 is connected to the groove. One end of the push plate 51 is inserted into the third mounting hole 411, and the other end of the push plate 51 extends to the outside of the third mounting hole 411, and the push plate 51 located outside extends in the direction toward the fuselage 1. The push plate 51 can slide along the length direction of the third mounting hole 411, that is, the push plate 51 moves in the direction away from the fuselage 1 or in the direction close to the fuselage 1. The end of the push plate 51 away from the fuselage 1 has an inclined surface. When the push plate 51 moves in a direction away from the fuselage 1, the inclined surface can abut against the locking rod 43 in the groove, and the locking rod 43 is pushed out of the groove under the push of the push plate 51, that is, unlocked. After the locking rod 43 is pushed out of the groove, the fixed column 31 rotates in a direction away from the fuselage 1 under the extrusion force of the overhead cable 8. During this process, the locking rod 43 abuts against the arc surface of the guide plate 41 and slides along the arc surface. In order to allow the push plate 51 to reset after movement, the push plate 51 is elastically connected to the guide plate 41. Specifically, a fourth mounting hole 54 is opened on the side of the guide plate 41 away from the fixed column 31. The fourth mounting hole 54 is a long hole. The length direction of the fourth mounting hole 54 is parallel to the movement direction of the push plate 51, and the fourth mounting hole 54 is connected to the third mounting hole 411. A slider 55 is provided on the push plate 51. The slider 55 passes through the fourth mounting hole 54 and extends to the outside of the fourth mounting hole 54. On the side of the guide plate 41 away from the fixing column 31, mounting plates are respectively arranged at both ends of the fourth mounting hole 54 in the length direction, a mounting rod is arranged between the two mounting plates, a slider 55 is inserted on the mounting rod, and the slider 55 can slide along the length direction of the mounting rod. A third spring 53 is sleeved on the mounting rod, one end of the third spring 53 is connected to the mounting plate close to the fuselage 1, and the other end is connected to the slider 55. When the push plate 51 moves, the third spring 53 can be driven to extend and retract through the slider 55. This structure is used to realize the elastic connection between the push plate 51 and the guide plate 41. It can be understood that when the pressing plate 52 pushes the push plate 51 to move in the direction away from the fuselage 1, the third spring 53 is driven to extend through the slider 55. When the pressing plate 52 loses the extrusion force, the elastic force of the third spring 53 can drive the push plate 51 to move in the direction of the fuselage 1, so as to realize the reset of the push plate 51.

[0039] Specifically, refer to Figure 6As shown, a socket 621 is provided on the movable block 62, and one end of the pressing plate 52 away from the fixing column 31 is connected to the socket 621 on the movable block 62, and the pressing plate 52 is installed on the hole wall of the socket 621, and the pressing plate 52 can rotate relative to the movable block 62. When the overhead cable 8 is separated from the wing 3, the reset device 6 drives the wing 3 to move to a locked state. During this process, the movable block 62 can drive the pressing plate 52 to rotate toward the direction of the fuselage 1, so that the pressing plate 52 is separated from the push plate 51.

[0040] Specifically, refer to Figure 3 As shown, the power inspection drone also includes a guide bar 7, which guides the movement of the overhead cable 8. The guide bar 7 is located below the blade assembly 32, and the guide bar 7 is an arc-shaped structure. One end of the guide bar 7 is connected to the fixed column 31, and the connection position of the two is located on the side of the fixed column 31 away from the blade assembly 32. The other end of the guide bar 7 is bent in the direction away from the blade assembly 32, and the end of the guide bar 7 away from the fixed column 31 extends toward the fuselage 1. The vertical distance from the end of the guide bar 7 away from the fixed column 31 to the fixed column 31 is greater than the vertical distance from the periphery of the blade assembly 32 to the fixed column 31. It can be understood that the guide bar 7 is arranged on the side of the fixed column 31 facing the fuselage 1, and when the wing 3 hangs the overhead cable 8, the overhead cable 8 abuts against the guide bar 7. When the wing 3 rotates, the overhead cable 8 moves along the extension direction of the guide bar 7 and detaches from the end of the guide bar 7 away from the fixed column 31. The guide bar 7 protects the blade assembly 32 , preventing the overhead cable 8 from contacting the blade assembly 32 and causing damage to the blade assembly 32 .

[0041] In this embodiment, the specific method for the power inspection drone to automatically escape is as follows: during normal flight, the wing 3 is in a locked state, and the wing 3 is perpendicular to the connector 2. In the locking device 4, the second spring 42 is compressed, and the elastic force of the second spring 42 presses the locking rod 43 against the groove of the guide plate 41. When the wing 3 is hooked on the overhead cable 8, the fuselage 1 falls freely due to the loss of power, and the force point of the entire drone weight is concentrated on the hooked wing 3. Under the extrusion force of the overhead cable 8, the overhead cable 8 squeezes the pressing plate 52 to rotate, and the pressing plate 52 drives the push plate 51 to move in the direction away from the fuselage 1. The push plate 51 pushes the locking rod 43 out of the groove to achieve unlocking. After unlocking, the wing 3 rotates around the first connection point 311 in the direction away from the fuselage 1, so that the angle between the wing 3 and the connector 2 increases. The overhead cable 8 slides along the guide bar 7 until it is completely separated from the guide bar 7, that is, the overhead cable 8 is separated from the wing 3. After the overhead cable 8 is detached, the pressure plate 52 loses the external pressure, and the push plate 51 moves toward the fuselage 1 under the rebound action of the third spring 53, that is, the push plate 51 is reset. At the same time, under the rebound action of the first spring 61, the movable block 62 drives the pressure plate 52 to rotate toward the fuselage 1, so that the pressure plate 52 is separated from the push plate 51. The first spring 61 drives the wing 3 to rotate toward the fuselage 1 through the second connection point 312 until the wing 3 is perpendicular to the connecting member 2. Finally, when the wing 3 is perpendicular to the connecting member 2, the locking rod 43 returns to the groove to achieve re-locking.

[0042] The beneficial effects of this embodiment are as follows: by rotating the wing 3 to be set at the free end of the connector 2, the wing 3 and the connector 2 are connected and fixed by the locking device 4. The locking device 4 is unlocked by the trigger device 5, so that the wing 3 can be rotated to change the angle between the wing 3 and the connector 2, so as to promote the detachment of the overhead cable 8 from the wing 3 and achieve automatic escape. After escaping, the wing 3 is reset by the reset device 6. The power inspection drone can automatically escape from the overhead cable 8, so that it is convenient to remove the power inspection drone when it is accidentally hung on the overhead cable 8.

[0043] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
