Description

Technical Field

[0001] The invention relates to the technical field of power transmission line deicing, and in particular to an impact ice cutting device and an airborne power transmission line ground wire deicing robot. Background Art

[0002] Transmission lines play an important role in transmitting electricity. In order to ensure the normal operation of power lines, they need to be regularly maintained. Ensuring the safe and reliable operation of transmission lines is of great significance to ensuring the stable development of the national economy. In colder windy and snowy weather, the ice-covered surface of ultra-high and ultra-high voltage ground wires is often covered with ice. In severe cases, the ground wires may be broken, resulting in dangerous accidents. Zhejiang and other places have suffered large-scale ice disasters, with severe ice coverage on transmission lines, and even tower collapse and line break accidents. According to the image analysis obtained on site, the ice body is mainly a mixed rime with rain pine as the main body. It is hard and difficult to remove. The thickness of the ice body on one side exceeds 10 cm, and the cross-section is circular or elliptical.

[0003] There are two main de-icing methods for power transmission lines: thermal de-icing and mechanical de-icing. Thermal de-icing usually uses the heat generated by the conductor itself to melt ice and snow, but its de-icing efficiency is not high and the operation is difficult. When the ground wire in the power transmission line is covered with ice, the ground wire is not charged and cannot generate heat to melt ice and snow like a charged conductor, that is, the thermal de-icing method cannot be used to remove ice. The mechanical de-icing method mainly removes ice by manual knocking and scraping or by mechanical knocking. Knocking or scraping can remove thinner ice layers, but when the ice is severely covered and the ice is hard, it is difficult to remove the ice by scraping or knocking. Summary of the invention

[0047] Furthermore, if Figure 1 and Figure 2As shown, the transmission mechanism 42 includes a driving gear 421, a driven gear 422 and a transmission shaft 423; the transmission shaft 423 is arranged in the installation cavity 10, and the two ends of the transmission shaft 423 are rotatably connected to the frame 1, and the transmission shaft 423 passes through the bottom surface of the frame 1 and extends to the bottom of the frame 1; the outer periphery of the transmission shaft 423 is provided with an external thread, and the transmission platform 43 is sleeved on the outer periphery of the transmission shaft 423 and is screwed with the transmission shaft 423; the driving gear 421 and the driven gear 422 are arranged horizontally and spaced below the frame 1, and the driving gear 421 and the driving gear 422 are spaced apart from each other. The power output end of the motor 41 is fixedly connected, the driving gear 421 is meshed with the driven gear 422, and the driven gear 422 is fixedly connected to the bottom end of the transmission shaft 423; through the transmission of the driving gear 421, the driven gear 422 and the transmission shaft 423, when the drive motor 41 is running, the driving gear 421 rotates, driving the driven gear 422 to rotate, and then driving the transmission shaft 423 to rotate, so that the transmission platform 43 with the transmission shaft 423 moves between the power storage position and the impact position in the vertical direction relative to the frame 1, that is, moves up and down in the vertical direction relative to the frame 1.

[0048] Furthermore, if Figure 1 to Figure 3As shown, a first direction X and a second direction Y are defined as being perpendicular to each other on a horizontal plane, and the transmission platform 43 is rotatably connected to the transmission member 441 on both side surfaces in the second direction Y. By arranging the transmission members 441 on both side surfaces of the transmission platform 43, the force of the mobile platform 23 when engaging with the transmission member 441 is balanced, so as to prevent the mobile platform 23 from being disengaged from the transmission member 441 due to unbalanced force, resulting in problems such as insufficient impact force; the rotation axis of the transmission member 441 is parallel to the second direction Y; the transmission platform 43 is provided with a connecting portion 431 extending outward on both side surfaces in the second direction Y; the second spring 442 is extended along the first direction X, and the upper end of the transmission member 441 is connected to the connecting portion 431 through the second spring 442.

The transmission platform 43 is slidably connected to the guide rail 102 to improve the stability of the transmission platform 43 when moving in the vertical direction relative to the frame 1.

[0052] Preferably, if Figure 1 and Figure 2 As shown, the frame 1 includes a top plate 11, a bottom plate 12, a first side plate 13 and a second side plate 14, the bottom plate 12 is spaced below the top plate 11, the first side plate 13 and the second side plate 14 are parallel to each other and spaced along the first direction X; the top and bottom ends of the first side plate 13 are respectively connected to the top plate 11 and the bottom plate 12; the top and bottom ends of the second side plate 14 are respectively connected to the top plate 11 and the bottom plate 12; the top plate 11, the bottom plate 12, the first side plate 13 and the second side plate 14 are jointly enclosed to form the installation cavity 10; this arrangement makes the two sides of the installation cavity 10 open, which is beneficial to the heat dissipation inside the installation cavity 10, and the structure is simple and easy to maintain.

[0054] Preferably, if Figure 1 and Figure 2 As shown, the bottoms of the two side surfaces of the first side plate 13 in the second direction Y are respectively provided with limit blocks, and the two limit blocks define and form the triggering portion 101 .

[0055] Furthermore, if Figure 1 and Figure 2As shown, in order to improve the reliability of the connecting member 32 so that the movement of the mobile platform 23 and the impact force carried by it can be effectively transmitted to the cutter head 31, the connecting member 32 includes a connecting head 321 and a pair of parallel connecting columns 322; the pair of connecting columns 322 are slidably penetrated in the frame 1, and the bottoms of the connecting columns 322 are connected to the top of the mobile platform 23; the pair of connecting columns 322 are connected to the cutter head 31 through the connecting head 321.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, since the connecting column 322 usually has a certain length, so that the first spring 22 that plays a major role in the impact process has a compression stroke of sufficient length, and the cutter head 31 also has a sufficiently long impact stroke, so as to meet the impact force required for ice cutting, in order to enable the connecting column 322 to remain parallel to the axis of the guide column 21 when moving up and down, so as to completely transmit the impact force to the cutter head 31 and avoid unnecessary loss, the connecting member 32 also includes a pair of sleeves 323, the axial direction of the pair of sleeves is parallel to the axial direction of the guide column 21, the pair of sleeves 323 are fixedly connected to the frame and pass through the inner and outer surfaces of the top of the frame 1, and the bottom end of the sleeve 323 extends into the mounting cavity 10; the connecting column 322 is slidably penetrated into the pair of sleeves 323 in a one-to-one correspondence.

[0057] Furthermore, if Figure 1 and Figure 2 As shown, the tip of the cutter head 31 is serrated, thereby enhancing the cutting ability of the cutter head 31, and the serrated tip can reduce impact and wear, thereby extending the service life of the cutter head 31.

[0059] In particular, in the description of the present invention, it should be understood that the term "airborne" used in the present invention means that the de-icing robot 1000 is designed to be carried on a certain carrier, usually an aircraft, such as a drone or other flying equipment, to perform de-icing tasks, that is, the de-icing robot 1000 can be deployed and recovered based on the drone.

[0060] Based on the above technical solution, the robot body 200 is set up on the ground wire of the transmission line, and the impact ice cutting device 100 is used to impact and cut the ice on the ground wire of the transmission line, so that the de-icing staff can perform remote control and other further settings to improve the safety of de-icing work.

[0061] The working process of the present invention is:

[0062] In the initial state, the transmission member 441 is in the power storage position, that is, the transmission member 441 is relatively located at the top of the frame 1, and the lap joint 4412 is located above the lap joint column 231; the driving motor 41 is controlled to rotate forward, and the driving gear 421 and the driven gear 422 drive the transmission shaft 423 to rotate, and then the transmission platform 43 is driven to move downward through the transmission shaft 423, so that the lap joint 4412 is engaged with the lap joint column 231, thereby driving the mobile platform 23 to move downward and compressing the first spring 22; when the When the transmission member 441 moves down to the impact position, the limiting portion 4411 of the transmission member 441 is connected to the limiting block, and the limiting block overcomes the action force of the second spring 442 to push the transmission member 441 to rotate, so that the overlapping portion 4412 is disengaged from the overlapping column 231, and the first spring 22 is released from the compressed state to the free state under the action of the elastic force, and the moving platform 23 connected to the first spring 22 transmits the elastic force to the cutter head 31, and the cutter head 31 impacts upward, and the tip of the top of the cutter head 31 rushes toward the ice layer to cut the ice layer.

[0063] After the blade head 31 cuts the ice layer, the driving motor 41 is controlled to reverse, and the transmission shaft 423 is driven to rotate via the driving gear 421 and the driven gear 422, and then the transmission platform 43 is driven to move upward through the transmission shaft 423, so that the overlapping part 4412 passes over the overlapping column 231 and is located above the overlapping column 231, thereby resetting to the initial state for the next impact ice cutting work.
