Description

Technical Field

[0001] The utility model relates to the technical field of deicing robots, in particular to a rotating ice-crushing structure of the deicing robot. Background Art

[0002] Microclimate regional disasters often occur on overhead lines that cross valleys, canyons, water systems, and other places that are difficult for people to reach. It is difficult for people to reach under the lines and perform manual de-icing. Moreover, DC de-icing technology cannot melt the ice on OPGW optical cables. When the sag of the OPGW optical cable line is too large, even if the line status of the transmission line below has been restored through DC de-icing technology, it will be affected by the sag of the OPGW optical cable and cannot safely transmit power. Therefore, de-icing robots have to be used to remove the ice from the OPGW optical cables.

[0003] However, in the prior art, the rotating ice-breaking structure of the de-icing robot mostly uses a reciprocating knocking method when working. After the ice-breaking structure collides with the ice layer, it will stop and rotate to reset, and then repeat this process again. The knocking force is relatively small and the ability to break the ice layer is weak. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a rotating ice-crushing structure for an ice-removing robot, which solves the technical problems in the existing technology that the rotating ice-breaking structure has insufficient knocking force when breaking ice and has weak ice-breaking ability. It has the advantage of being able to keep the ice-breaking structure in a rotating state without stopping midway, which can effectively increase the knocking force.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a rotating ice-crushing structure of an ice-removing robot, comprising a first clamping arm and a second clamping arm hinged to each other, and a suspension ring is fixedly installed on the first clamping arm and the second clamping arm, and a cable driving mechanism is provided inside the first clamping arm and the second clamping arm, and the sides of the first clamping arm and the second clamping arm are respectively provided with a knocking ice-crushing mechanism. During the ice crushing operation, the first clamping arm and the second clamping arm will move along the cable under the action of the cable driving mechanism, and the knocking ice-crushing mechanism will remove the ice on the cable during the movement. The knocking ice-crushing mechanism includes side wall grooves respectively opened on the inner sides of the first clamping arm and the second clamping arm, and a driving motor is fixedly installed inside the side wall grooves. Rotating blocks are symmetrically arranged on the first clamping arm and the second clamping arm, and a sliding round rod is fixedly installed on the rotating block. A knocking pendulum block is slidably connected to the sliding round rod. When the rotating square rotates, the knocking pendulum block will rotate synchronously, and when the knocking pendulum block rotates, it will contact the ice on the cable, thereby completing the ice-breaking operation.

[0006] Preferably, the cable driving mechanism includes a rectangular slide symmetrically arranged on the first clamping arm and the second clamping arm, a sliding nut is movably installed inside the rectangular slide, and the sliding nut is provided with a screw assembly for bringing the first clamping arm and the second clamping arm closer to each other, and a wheel mounting box is movably installed on the first clamping arm and the second clamping arm, and a driving wheel is provided inside the wheel mounting box. After the first clamping arm and the second clamping arm clamp both sides of the cable, the driving wheel will automatically be powered on and rotated, thereby causing the first clamping arm and the second clamping arm to move horizontally along the cable.

[0007] Preferably, the screw assembly includes a sliding protrusion movably mounted on the second clamping arm, and a driving screw is movably mounted on the sliding protrusion. The driving screw is threadedly engaged with the sliding nut. When the driving screw rotates around its own axis, the lower ends of the first clamping arm and the second clamping arm are brought closer to each other.

[0008] Preferably, the sliding protrusion and the sliding nut can both move up and down along the rectangular sliding groove, thereby preventing the driving screw from interfering with the relative movement of the first clamping arm and the second clamping arm.

[0009] Preferably, the rotating block is in transmission connection with the output end of the driving motor, and when the driving motor is powered on, the rotating block will rotate rapidly.

[0010] Preferably, a return spring is sleeved on the outer side of the sliding round rod, and when the knocking pendulum block comes into contact with ice during the rotation process, the knocking pendulum block and the rotating block are brought closer to each other.

[0011] By means of the above technical solution, the present invention provides a rotating ice crushing structure of an ice removal robot, which has at least the following beneficial effects:

[0012] 1. The utility model is provided with a knocking ice-breaking mechanism. The knocking pendulum block and the sliding round rod cooperate with each other to automatically knock the ice layer on the cable surface from the side and break it, so that the ice layer falls off, which can quickly relieve the cable sag and restore power supply. Moreover, the knocking pendulum block can automatically retract when it comes into contact with the ice layer and does not need to stop. Therefore, the knocking pendulum block will always be in a rotating state instead of a reciprocating rotating state, which can effectively increase the crushing force.

[0013] 2. The utility model sets up a cable drive mechanism and utilizes the mutual cooperation between the screw assembly and the driving wheel to enable the ice-breaking structure to move along the OPGW optical cable, thereby quickly completing the ice-breaking operation without the need for manual operation by the staff, which can effectively improve the efficiency of the ice-breaking operation.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] In the prior art, the rotating ice-breaking structure of the de-icing robot mostly uses a reciprocating striking method when working. After the ice-breaking structure collides with the ice layer, it stops and rotates back to its original position, and then repeats the process again. The striking force is relatively small, and the ability to break the ice layer is relatively weak. In order to solve this technical defect in the prior art, Figures 1-4 As shown, this embodiment proposes a rotating ice-crushing structure of an ice-removing robot, which can automatically knock and break the ice layer on the surface of the cable from the side, causing the ice layer to fall, and can quickly relieve the cable sag. The first clamping arm 1 and the second clamping arm 2 of the structure are fixedly installed with a hanging ring 3, and the interior of the first clamping arm 1 and the second clamping arm 2 are provided with a cable driving mechanism 4, and the sides of the first clamping arm 1 and the second clamping arm 2 are respectively provided with a knocking and ice-crushing mechanism 5. During the ice crushing operation, the first clamping arm 1 and the second clamping arm 2 will move along the cable under the action of the cable driving mechanism 4, and the knocking and ice-crushing mechanism 5 will remove the ice on the cable during the movement.

[0023] In order to enable the structure to automatically move horizontally along the cable, the present embodiment provides a cable drive mechanism 4. Specifically, the cable drive mechanism 4 includes a rectangular slot 401 symmetrically provided on the first clamping arm 1 and the second clamping arm 2. A sliding nut 402 is movably installed inside the rectangular slot 401. The sliding nut 402 is provided with a screw assembly 403 that brings the first clamping arm 1 and the second clamping arm 2 closer to each other. The screw assembly 403 includes a sliding protrusion movably installed on the second clamping arm 2. The sliding protrusion and the sliding nut 402 can both move up and down along the rectangular slot 401, thereby preventing the driving screw from contacting the first clamping arm 1 and the second clamping arm 2. The relative movement of the clamping arm 1 and the second clamping arm 2 causes interference. A driving screw is movably installed on the sliding protrusion, and the driving screw is threadedly matched with the sliding nut 402. When the driving screw rotates around its own axis, the lower ends of the first clamping arm 1 and the second clamping arm 2 are close to each other. A wheel mounting box 404 is movably installed on the first clamping arm 1 and the second clamping arm 2. A driving wheel 405 is provided inside the wheel mounting box 404. After the first clamping arm 1 and the second clamping arm 2 clamp both sides of the cable, the driving wheel 405 will automatically be powered on and rotated, thereby causing the first clamping arm 1 and the second clamping arm 2 to move horizontally along the cable.

[0024] In order to quickly break the ice layer on the cable, the present embodiment provides a knocking ice crushing mechanism 5. Specifically, the knocking ice crushing mechanism 5 includes side wall grooves 501 respectively provided on the inner sides of the first clamping arm 1 and the second clamping arm 2. A driving motor 503 is fixedly installed inside the side wall groove 501. Rotating blocks 502 are symmetrically provided on the first clamping arm 1 and the second clamping arm 2. The rotating blocks 502 are transmission-connected to the output end of the driving motor 503. When the driving motor 503 is powered on, the rotating blocks 502 are 02 rotates quickly. A sliding round rod 505 is fixedly installed on the rotating block 502. A knocking pendulum block 504 is slidably connected to the sliding round rod 505. When the rotating block 502 rotates, the knocking pendulum block 504 will rotate synchronously. When the knocking pendulum block 504 rotates, it will contact the ice on the cable, thereby completing the ice-breaking operation. A return spring 506 is provided on the outer side of the sliding round rod 505. When the knocking pendulum block 504 contacts the ice during rotation, the knocking pendulum block 504 and the rotating block 502 will approach each other.

[0025] When the rotating ice-breaking structure is in use, first, the staff will use a soft rope to fix the hanging ring 3 to the drone, and then the staff will control the drone to transport the ice-breaking structure above the OPGW optical cable.

[0026] Subsequently, the first clamping arm 1 and the second clamping arm 2 will approach each other under the action of the screw assembly 403, so that the OPGW optical cable is located in the middle of the four driving wheels 405. Next, the driving wheels 405 will rotate at a constant speed under the action of the micro motor, so that the ice-breaking structure moves horizontally along the OPGW optical cable.

[0027] During the movement, the two rotating blocks 502 will rotate rapidly under the action of the driving motor 503. When the rotating blocks 502 rotate, the knocking pendulum block 504 will rotate synchronously. When the knocking pendulum block 504 rotates, it will collide with the side of the ice layer, thereby breaking the ice layer and causing it to fall.

[0028] Moreover, according to Figure 3 It can be seen that when the striking pendulum 504 contacts the ice layer during its rotation, the striking pendulum 504 will gradually shrink, so that the striking pendulum 504 is always in a rotating state and will not stop moving due to being blocked by the ice layer, which can effectively increase the force of breaking ice.

[0029] This embodiment provides a knocking and ice-breaking mechanism 5, and utilizes the mutual cooperation between the knocking pendulum block 504 and the sliding round rod 505 to automatically knock and break the ice layer on the cable surface from the side, so that the ice layer falls, which can quickly alleviate the cable sag and restore power supply. Moreover, the knocking pendulum block 504 can automatically shrink when it contacts the ice layer without stopping, so the knocking pendulum block 504 will always be in a rotating state instead of a reciprocating rotating state, which can effectively improve the crushing force; in addition, this embodiment provides a cable driving mechanism 4, and utilizes the mutual cooperation between the screw assembly 403 and the driving wheel 405 to enable the ice-breaking structure to move along the OPGW optical cable, thereby quickly completing the ice-breaking operation without the need for manual operation by the staff, which can effectively improve the efficiency of the ice-breaking operation.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
