The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0047] like Figure 1 , 2 As shown, a novel spacer fixing device is characterized by comprising a fixing frame 1, a movable block 2, a cable fixing assembly 3, a spacer 4, and a through-type linear motor 51.

[0048] The fixed frame 1 has hooks 8 and mounting bases 9 at both ends of its surface, and its back is fixedly connected to the spacer 4.

[0049] A movable block 2 is provided between the mounting base 9 and the hook 8;

[0050] The movable block 2 is slidably connected to the fixed frame 1;

[0051] The cable fixing assembly 3 includes a first fixing block 31 and a second fixing block 32;

[0052] The first fixed block 31 is connected to the side of the movable block 2 near the hook 8;

[0053] The second fixing block 32 is disposed inside the hook portion 8;

[0054] The surfaces of the first fixing block 31 and the second fixing block 32 that are close to each other are respectively provided with clamps 61 for the cable 100 to pass through;

[0055] After the first fixing block 31 and the second fixing block 32 are tightly fitted together, the two clamp jaws 61 form a wire passage hole 6;

[0056] The through-type linear motor 51 is connected to the mounting base 9, and its driving end is a push rod 52 connected to the movable block 2.

[0057] The push rod 52 of the through-type linear motor 51 axially pushes the movable block 2 to make the first fixed block 31 and the second fixed block 32 fit together;

[0058] A limit mechanism 7 is provided on the fixed frame 1 near the connecting end of the hook 8;

[0059] The limiting mechanism 7 is used to restrict the separation of the first fixing block 31 and the second fixing block 32.

[0060] In this embodiment, by using a through-type linear motor 51 to drive the movable block 2, the transmission structure is simplified and the efficient and responsive driving of the movable block 2 is improved.

[0061] In this embodiment, the overall structure is compact, and the limiting mechanism 7 solves the problem of easy loosening of traditional devices.

[0062] In this embodiment, a magnetic connector (not shown in the figure) is provided on the outer side of the housing of the through-type linear motor 51, so that the through-type linear motor 51 is magnetically connected to the power supply connector of the UAV through the magnetic connector; after the movable block 2 is in place, the power supply connector of the UAV can be separated from the magnetic connector by controlling the UAV to move away from the device.

[0063] Furthermore, such as Figure 1 , 2 As shown, the surface of the fixing frame 1 is provided with a mounting groove 11;

[0064] The limiting mechanism 7 includes a limiting plate 71 and a spring 72;

[0065] The limiting plate 71 is disposed in the mounting groove 11. One end of the plate near the mounting base 9 is rotatably connected to the fixing frame 1 via a rotating shaft, and the other end is provided with a ratchet 711 with teeth facing the hook 8.

[0066] A spring 72 is provided between the lower part of the limiting plate 71 and the mounting groove 11;

[0067] The spring 72 causes one end of the limiting plate 71 with the ratchet 711 to protrude from the mounting groove 11;

[0068] The two ends of the spring 72 are fixedly connected to the limiting plate 71 and the fixing frame 1, respectively;

[0069] The ratchet 711 engages with the movable block 2 when the first fixed block 31 and the second fixed block 32 are in contact.

[0070] In this embodiment, in the initial state, one end of the ratchet 711 of the limiting plate 71 protrudes from the mounting groove 11 under the action of the spring 72; when the movable block 2 and the second fixed block 32 slide above the limiting plate 71, the limiting plate 71 changes from an inclined state to a horizontal state and is built into the mounting groove 11 under the pressure of the movable block 2; when the second fixed block 32 is in contact with the first fixed block 31, the spring 72 drives the limiting plate 71 to rotate around the axis of the rotating shaft, so that the end of the limiting plate 71 with the ratchet 711 is reset and engaged with the movable block 2, thereby realizing automatic locking, preventing the movable block 2 from retracting, and enhancing the vibration resistance.

[0071] Furthermore, such as Figure 1 , 2 As shown, the wire hole 6 is an eccentric wire hole 6 located near the connecting end of the hook part 8.

[0072] In this embodiment, the eccentric wire hole 6 reduces the overturning moment, avoids local stress concentration, and provides multi-directional constraints under wind vibration conditions, making the connection between the wire hole 6 and the cable 100 more stable and reliable.

[0073] Furthermore, such as Figure 1, 2 As shown, in order to ensure that the cable 100 can smoothly and reliably enter the jaws 61 during installation, the cable 100 is directly inserted into the wire hole 6; the wire hole 6 is close to the surface of the connecting end of the hook 8.

[0074] Furthermore, such as Figure 1 , 2 As shown, to ensure stable and accurate driving, the through-type linear motor 51 is a through-shaft screw linear stepper motor.

[0075] Furthermore, in order to prevent damage to the cable 100 and improve insulation safety, the first fixing block 31 and the second fixing block 32 are insulating rigid elastic components.

[0076] In this embodiment, in order to accommodate different cable diameters 100, the first fixing block 31 and the second fixing block 32 are respectively connected to the movable block 2 and the hook 8 by means of screw locking.

[0077] Furthermore, the insulating rigid elastic element is made of rubber, polyurethane elastomer, or fiber-reinforced elastomer.

[0078] Furthermore, such as Figure 1 , 2 As shown, in order to improve overall strength and durability and reduce assembly steps, the mounting base 9, the fixing frame 1 and the hook 8 are integrally formed structures.

[0079] The workflow of this utility model is described in conjunction with the accompanying drawings:

[0080] Initial state ( Figure 1 The movable block 2 is located on the side of the mounting base 9. The first fixing block 31 and the second fixing block 32 are separated. Under the control of the drone, the cable 100 is made to stick tightly to the surface of the fixing frame 1.

[0081] Drive phase: The UAV is powered by the magnetic ring. The push rod 52 of the through linear motor 51 axially pushes the movable block 2 and the second fixed block 32 toward the hook 8, so that the cable 100 is close to the jaw 61.

[0082] Locking phase ( Figure 2 The first fixing block 31 and the second fixing block 32 fit together to form a wire hole 6, at which time the cable 100 is placed in the wire hole 6; the ratchet 711 of the limiting plate 71 engages with the movable block 2, and the spring 72 keeps it locked, thereby fixing the cable 100.

[0083] Separation operation: By controlling the drone away from the device, the drone charging end that is magnetically attracted to each other is separated from the magnetic connector, so that the device can be fixedly installed on the cable 100.

[0084] This invention achieves efficient and reliable installation of the spacer bar 4 through the above structure, and is especially suitable for drone operations in complex environments.

[0085] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
