Electrically controlled lock structure for drone spacer installation

Abstract

This utility model discloses an electrically controlled lock structure for installing spacer bars on drones, comprising: a spacer bar; a locking mechanism installed at both ends of the spacer bar to fix the spacer bar between multiple wires; a drive assembly for driving the locking mechanism to clamp the spacer bar to the outside of the wires; and a power supply configured on the locking mechanism to supply power to the drive assembly. After the wires are clamped by the cooperation between the moving clamp and the fixed clamp, during the process of the drone flying away from the spacer bar, the insert rod can be pulled out of the pivot, and the positioning pin can also be moved out of the positioning hole, so that the power supply can be detached from the base. Therefore, through this mechanism, during the process of the spacer bar clamping the outside of the wires, the power supply can be released from the locked state of the base, so that the drone can lift the power supply off the base, thereby reducing the overall weight of the spacer bar and increasing the stability of the spacer bar fixed to the wires.

Description

Technical Field

[0001] This utility model relates to the field of spacer installation technology, and in particular to an electrically controlled lock structure for installing spacers in unmanned aerial vehicles. Background Technology

[0002] Spacer bars are electrical fittings used in overhead lines (especially high-voltage and ultra-high-voltage transmission lines). Their main function is to maintain the distance between split conductors, prevent the conductors from colliding and rubbing against each other under the action of wind, electromagnetic force or vibration, and at the same time suppress the vibration of the conductors in the wind, ensuring the safe and stable operation of the line.

[0003] Spacers are typically connected to power lines via clamps at their ends. When spacers are installed between multiple power lines using drones, the clamps are usually driven by electronic control. This requires the related drive components and external power supply to be mounted on the clamps, which increases the weight of the clamps and increases the overall pressure of the spacers on the power lines, making it difficult to maintain the stability of the spacers on the power lines.

[0004] Therefore, it is necessary to provide an electrically controlled lock structure for the installation of spacer bars on drones to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electrically controlled lock structure for installing spacer bars for drones, in order to solve the problem mentioned in the background art that existing spacer bars are generally connected to wires through clamps at their ends. When spacer bars are installed between multiple wires by drone hoisting, the clamps are generally driven by electrical control, which leads to the need to configure related driving components and external power supplies on the clamps, thereby increasing the weight of the clamps.

[0006] Based on the above ideas, this utility model provides the following technical solution: an electrically controlled lock structure for installing spacer bars on unmanned aerial vehicles, comprising:

[0007] Spacer bars;

[0008] A locking mechanism is installed at both ends of the spacer to fix the spacer between multiple wires;

[0009] A drive assembly for driving the locking mechanism to clamp the wire to the outside;

[0010] A power supply, configured on the locking mechanism, provides power to the drive assembly;

[0011] The locking mechanism includes a base, with fixed clamps and movable clamps arranged on both sides below the base. The driving component can drive the movable clamps to approach the fixed clamps to clamp the wires.

[0012] As a further embodiment of this utility model: the driving assembly includes a lead screw and a guide post rotatably mounted between the vertical surface of the base and the fixed clamp. The guide post passes through the slide on the movable clamp and slides with the slide. The lead screw passes through the movable clamp and threadedly engages with the movable clamp.

[0013] As a further embodiment of this utility model: the power supply is detachably connected to the base, and the power supply is provided with a traction rope for connecting to the drone.

[0014] As a further embodiment of this utility model: a rotating shaft is rotatably mounted on the base, an annular groove is provided on the top end face of the rotating shaft, and a slot is provided at the annular groove. A plug rod is fixedly mounted on the outer shell of the power supply, and a protrusion is fixed on the outer circumference of the plug rod. Initially, the plug rod is inserted into the rotating shaft so that the protrusion is located in the annular groove and offset from the slot.

[0015] As a further embodiment of this utility model: an arc-shaped groove is provided on the outer circumference of the guide post, and a limiting block that slides in cooperation with the arc-shaped groove is fixedly provided on the inner wall of the slide block. When the guide post is rotated by the cooperation of the limiting block and the arc-shaped groove, the guide post can synchronously drive the rotating shaft to rotate so that the groove opening is aligned with the protrusion.

[0016] As a further embodiment of this utility model: a sliding groove is provided on the outer circumference of the guide post at both ends of the arc groove, the sliding groove is parallel to the axis of the guide post and is connected to the arc groove.

[0017] As a further embodiment of this utility model: the fixing clamp has a hollow structure inside, and a motor is installed inside the fixing clamp, so that one end of the lead screw extending into the fixing clamp is connected to the output shaft of the motor for transmission.

[0018] As a further embodiment of this utility model: the opposite sides of the fixed clamp and the movable clamp are both provided with an inwardly recessed arc opening.

[0019] As a further embodiment of this utility model: the top of the base is provided with a plurality of positioning holes, and the outer shell of the power supply is fixedly provided with positioning posts that cooperate with the positioning holes.

[0020] As a further embodiment of this utility model: a driving bevel gear is fixedly provided at one end of the rotating shaft that passes downward through the base, and a driven bevel gear that meshes with the driving bevel gear is fixedly sleeved on the outer side of the guide column.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: when the wire is clamped by the cooperation between the movable clamp and the fixed clamp, during the process of the drone flying away from the spacer bar, the plug rod can be pulled out of the pivot, and the positioning pin can also be moved out of the positioning hole, so that the power supply can be separated from the base. Therefore, through this mechanism, during the process of the spacer bar clamping the outside of the wire, the power supply can be released from the locked state of the base, so that the drone can lift the power supply away from the base, thereby reducing the overall weight of the spacer bar and increasing the stability of the spacer bar fixed on the wire.

[0031] like Figures 1-7 As shown, the electrically controlled locking structure for installing spacer bars on a drone includes a spacer bar 1 and locking mechanisms installed at both ends of the spacer bar 1. The locking mechanism includes an L-shaped base 2 and fixed clamps 201 and movable clamps 202 located on both sides below the base 2. (Refer to...) Figures 1-2As shown, the fixed clamp 201 is fixed to the bottom of the base 2 by bolts and is fixedly connected to the spacer 1. The movable clamp 202 can move relative to the fixed clamp 201. Specifically, a drive component that cooperates with the movable clamp 202 is arranged at the fixed clamp 201. In actual use, the spacer 1 is hoisted under the drone and the drone is used to hoist the spacer 1 to the wire, so that the fixed clamp 201 and the movable clamp 202 fall on both sides of the wire. Then, the drive component drives the movable clamp 202 to approach the fixed clamp 201 to clamp the wire, so that the spacer 1 can be installed between the two wires.

[0032] Furthermore, both the fixed clamp 201 and the movable clamp 202 have an inwardly recessed arc opening 3 on their opposite sides. Preferably, the arc opening 3 is a semi-circular structure, and a rubber pad needs to be fixed on the inner wall of the arc opening 3. Through this structure, the wire can be more stably clamped between the fixed clamp 201 and the movable clamp 202.

[0033] Combination Figures 1-7 As shown, the driving assembly includes a lead screw 7 and a guide post 8 rotatably mounted between the vertical surface of the base 2 and the fixed clamp 201. A slide block 12 is fixedly installed in the pre-set through hole of the guide post 8, and the guide post 8 passes through the slide block 12 and slides with it. The lead screw 7 passes through the movable clamp 202 and is threaded with it. The fixed clamp 201 has a hollow structure inside, and a motor is installed inside the fixed clamp 201, so that one end of the lead screw 7 extending into the fixed clamp 201 is connected to the output shaft of the motor, so that the motor can drive the lead screw 7 to rotate. When the UAV lowers the locking mechanism to the outside of the wire, the motor drives the lead screw 7 to rotate, thereby causing the movable clamp 202 to approach the fixed clamp 201 and clamp the wire, thus completing the installation of the spacer 1. Specifically, a shield can be configured on the base 2 so that the operation and control of the motor are not affected.

[0034] In actual use, the power supply 4 that supplies power to the motor can be fixed on the base 2. However, considering the overall weight of the locking mechanism, as another way to install the power supply 4, the power supply 4 can be plugged into the base 2, so that the power supply 4 and the base 2 are detachably connected. Specifically, the plug connected to the motor can be plugged into the socket arranged on the power supply 4 so that the power supply 4 can supply power to the motor. Alternatively, the power supply 4 and the motor can be connected through mutually attached metal conductive sheets so that the power supply 4 can supply power to the motor. The power supply 4 is connected to the drone through the traction rope 6. After the spacer 1 is fixed to the two wires, the drone can be used to take the power supply 4 away from the spacer 1, thereby reducing the load of the spacer 1 on the wires.

[0035] Combination Figure 4As shown, multiple positioning holes 203 are provided on the top of the base 2, and positioning pins 11 that cooperate with the positioning holes 203 are fixedly provided on the outer shell of the power supply 4. The cooperation between the positioning pins 11 and the positioning holes 203 can prevent the power supply 4 from moving in the horizontal direction relative to the base 2.

[0036] Furthermore, combined Figures 3-6 As shown, the base 2 has a through hole, and a stepped rotating shaft 9 is rotatably mounted at the through hole via a bearing. An annular groove 901 is formed on the top end face of the rotating shaft 9. Figure 6 As can be seen, two slots 902 connected to the annular groove 901 are opened on the top surface of the rotating shaft 9. The two slots 902 are symmetrical about the axis of the rotating shaft 9. A plug rod 10 is fixedly installed on the outer shell of the power supply 4. Two protrusions 1001 are fixedly installed on the outer peripheral wall of the plug rod 10. The two protrusions 1001 are symmetrical about the axis of the plug rod 10. Initially, the positioning post 11 is inserted into the positioning hole 203, and the plug rod 10 is inserted into the rotating shaft 9 so that the protrusions 1001 are located in the annular groove 901. Specifically, the line connecting the two protrusions 1001 is perpendicular to the line connecting the two slots 902. The cooperation between the protrusions 1001 and the annular groove 901 can prevent the power supply 4 from moving in the vertical direction relative to the base 2. At this point, the power supply 4 is completely locked on the base 2, so that the spacer 1 can be lifted as a whole by the cooperation of the traction rope 6 and the power supply 4.

[0037] Combination Figures 3-5 As shown, an arc-shaped groove 801 is formed on the outer circumferential surface of the guide post 8. The shape of the arc-shaped groove 801 can be regarded as a segment cut from a spiral. A sliding groove 802 is formed on the outer circumferential surface of the guide post 8 at both ends of the arc-shaped groove 801. The sliding groove 802 is parallel to the axis of the guide post 8 and is connected to the arc-shaped groove 801. A limiting block 1201 is fixedly provided on the inner wall of the slide block 12, so that the limiting block 1201 can slide along the sliding groove 802 and the arc-shaped groove 801. A driving bevel gear is fixedly provided at one end of the rotating shaft 9 that passes downward through the base 2, and a driven bevel gear that meshes with the driving bevel gear is fixedly sleeved on the outer side of the guide post 8.

[0038] In practical use, a lifting ring 5 can be fixedly installed on the outer shell of the power supply 4, and a traction rope 6 is fixedly connected between the lifting ring 5 and the drone, so that the drone can lift the spacer 1 as a whole. Initially, the limiting block 1201 is located in the slide groove 802. When the drone lifts the spacer 1 to the power line and lowers the spacer 1 so that the fixed clamp 201 and the moving clamp 202 are located outside the power line, the drone remains in a hovering state and the operator controls the motor to drive the lead screw 7 to rotate, thereby causing the moving clamp 202 to gradually approach the fixed clamp 201. During this process, the limiting block 1201 will slide from the slide groove 802 into the arc groove 801. Through the cooperation of the limiting block 1201 and the arc groove 801, the guide column 8 can be rotated. Specifically, when the limiting block 1201 slides from the arc groove 801 into the slide groove... When the spacer is inside 802, the guide post 8 can rotate 90°, and then through the meshing of the active bevel gear and the driven bevel gear, it can drive the rotating shaft 9 to rotate 90° synchronously, so that the protrusion 1001 is aligned with the slot 902, so that the insertion rod 10 can be separated from the rotating shaft 9. When the wire is clamped by the cooperation between the moving clamp 202 and the fixed clamp 201, during the process of the drone flying away from the spacer 1, the insertion rod 10 can be pulled out of the rotating shaft 9, and the positioning post 11 can also be moved out of the positioning hole 203, so that the power supply 4 can be separated from the base 2. Therefore, through this mechanism, during the process of the spacer 1 being clamped on the outside of the wire, the power supply 4 can be released from the locked state of the base 2, so that the drone can lift the power supply 4 away from the base 2, thereby reducing the overall weight of the spacer 1 and increasing the stability of the spacer 1 fixed on the wire.

[0039] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
