Description

TECHNICAL FIELD

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

[0002] The power transmission line plays an important role in power transmission. In order to ensure the normal operation of the power line, it is necessary to regularly maintain the power transmission line. Ensuring the safe and reliable operation of the power transmission line is of great significance to the stable development of the national economy. In cold and snowy weather, the ice layer on the surface of the super and ultra-high voltage ground wire is often covered with ice, which may even cause the ground wire to be crushed, resulting in dangerous accidents. Zhejiang and other places have suffered large-scale ice disasters, and the power transmission line is covered with ice, and even tower collapse and wire breakage accidents have occurred. According to the analysis of the images obtained on site, the ice body is mainly mixed with rain and pine, the texture is hard and difficult to remove, the single-sided thickness of the ice body is more than 10 cm, and the cross section is circular or elliptical.

[0003] The existing deicing methods for power transmission lines mainly include thermal ice melting method and mechanical deicing method. The thermal ice melting method usually uses the heat generated by the conductor itself to melt the ice and snow, but the ice melting 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 cannot generate heat to melt the ice and snow like the live conductor, that is, the thermal ice melting method cannot be used for deicing. The mechanical deicing method mainly realizes deicing by artificial knocking, scraping or mechanical knocking.

[0039] The frame 1 is provided with a mounting cavity 10 extending vertically;

[0040] The force storage assembly 2 is disposed in the mounting cavity 10 and includes a guide column 21, a first spring 22, and a movable platform 23. The two ends of the guide column 21 are respectively fixed to the frame 1, the first spring 22 is sleeved on the outer periphery of the guide column 21, and the movable platform 23 is slidably sleeved on the outer periphery of the guide column 21.

[0041] The ice cutting assembly 3 includes a blade head 31 and a connecting member 32. The connecting member 32 is slidably provided on the frame 1. The blade head 31 is connected to the top of the connecting member 32 and is located above the frame 1. The blade head 31 is connected to the mobile platform 23 via the connecting member 32. The top of the blade head 31 is a pointed end.

[0042] The power assembly 4 includes a drive motor 41, a transmission mechanism 42, a transmission platform 43, and a transmission component 44; the drive motor 41 is mounted on the frame 1, the power output end of the drive motor 41 is connected to the power input end of the transmission mechanism 42, the transmission platform 43 is located in the mounting cavity 10, and is connected to the power output end of the transmission mechanism 42.

[0046] Based on the above technical solution, the drive motor 41 is driven by the transmission mechanism 42 to drive the transmission platform 43 to move between the power storage position and the impact position relative to the frame 1 in the vertical direction. When the transmission platform 43 is in the power storage position, the transmission member 441 engages with the movable platform 23 under the action of the second spring 442; and when the transmission platform 43 moves downward from the power storage position, the transmission member 441 drives the movable platform 23 to move downward and compresses the first spring 22; when the transmission platform 43 moves to the impact position, the triggering part 101 overcomes the action of the second spring and pushes the transmission member 441 to rotate to disengage from the movable platform 23, and the first spring 22 returns from the compressed state to the natural state. The elastic force of the first spring 22 causes the movable platform 23 to impact upward, and through the connection of the connecting member 32, it drives the tip of the top of the blade head 31 to rush towards the ice layer, so as to cut the thick ice layer through the impact force, thereby achieving the purpose of removing thick ice. In addition, the impact ice cutting device 100 utilizes the elastic force of the first spring 22 to achieve impact ice cutting. The overall structure is simple and stable, the working efficiency is high, and the impact stroke is controllable, and will not cause scratches or other damage to the power transmission line; and the cutter head 31 is connected to the mobile platform 23 through the connector 32, which is convenient for the individual replacement of the cutter head 31 to reduce the subsequent maintenance cost; compared with the thermal ice melting method that requires power supply and corresponding control equipment to perform de-icing work, the impact ice cutting device 100 only needs to be driven and controlled by the drive motor 41, so that the impact ice cutting device 100 is relatively simple as a whole, which is conducive to reducing production and maintenance costs and is convenient for promotion and use.

[0047] Further, 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 mounting 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 screwed with the transmission shaft 423; the driving gear 421 and the driven gear 422 are arranged horizontally and spaced apart below the frame 1, and the driving gear 421 and the driving gear 421 are connected to the driving gear 421. 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 driving 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 storage position and the impact position in the vertical direction relative to the frame 1, that is, it moves up and down in the vertical direction relative to the frame 1.

[0048] Furthermore, if Figures 1 to 3As shown, a first direction X and a second direction Y perpendicular to each other are defined 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 movable platform 23 is balanced when it is engaged with the transmission member 441, so as to prevent it from being disengaged from the transmission member 441 due to uneven 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 through the second spring 442. The transmission member 441 is connected to the part 431; the lower end of the transmission member 441 is provided with a limiting portion 4411, and the limiting portion is extended in the direction away from the second spring 442, and the trigger portion 101 is spaced below the limiting portion 4411; through the limiting portion 4411 provided at the lower end of the transmission member 441 and the trigger portion 101 spaced below the limiting portion 4411, when the transmission member 441 moves to the impact position, the limiting portion 4411 is connected with the trigger portion 101, and when the transmission member 441 continues to move downward, the limiting block of the trigger portion 101 is used to overcome the action force of the second spring 442, so that the transmission member 441 rotates, thereby disengaging from the moving platform 23, and then the first spring 22 is restored from the compressed state to the natural state.

[0049] Furthermore, if Figures 1 to 3 As shown, the upper end of the transmission member 441 is provided with a lap portion 4412, which extends in a direction away from the second spring 442, and the lap portion 4412 is spaced above the limit portion 4411; the two side surfaces of the movable platform 23 in the second direction are both provided with lap columns 231 extending outward, and when the transmission platform 43 is located in the storage position, the lap portion 4412 of the transmission member 441 overlaps with the lap column 231 of the movable platform 23 under the action of the second spring; when the transmission platform 43 moves to the impact position, the trigger part 101 overcomes the action of the second spring 442, and pushes the transmission member 441 to rotate until the lap portion 4412 is disengaged from the lap column 231 of the movable platform 23; through the cooperation between the lap portion 4412 and the lap column 231, the reliability of the transmission member 441 and the movable platform 23 during the engagement and movement process is improved.

[0050] Preferably, if Figures 1 to 3As shown, when the transmission member 441 returns to the power storage position, since the connecting column 231 will be above the connecting portion 4412, the connecting portion 4412 needs to pass over the connecting column 231 to return to the power storage position for the next power storage. The side surface of the connecting portion 4412 relative to the connecting column 231 is an inclined surface inclined from top to bottom, so that the transmission member 441 can pass over the connecting column 231.

[0051] Furthermore, if Figure 1 and Figure 2 As shown, a guide rail 102 is installed in the installation cavity 10, and the guide rail 102 extends in the vertical direction relative to the frame 1. The transmission platform 43 is slidably connected to the guide rail 102; so as 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 apart below the top plate 11, the first side plate 13 and the second side plate 14 are parallel to each other and spaced apart 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 jointly enclose 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 has a simple structure and is easy to maintain.

[0053] Preferably, if Figure 1 and Figure 2 As shown, the guide rail 102 is provided on a side surface of the second side plate 14 opposite to the first side plate 13 , so as to facilitate the installation and positioning of the guide rail 102 .

[0054] Preferably, if Figure 1 and Figure 2 As shown, the bottoms of both side surfaces of the first side plate 13 in the second direction Y are respectively provided with limiting blocks, and the two limiting 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 piece 32 and effectively transmit the moving and impact force of the moving platform 23 to the cutter head 31, the connecting piece 32 comprises a connecting head 321 and a pair of parallel connecting columns 322; the connecting columns 322 are slidably arranged in the rack 1, and the bottom of each connecting column 322 is connected to the top end of the moving platform 23; the connecting columns 322 are connected to the cutter head 31 through the connecting head 321.

[0056] Further, as shown in Figure 1 and Figure 2 Since the connecting columns 322 generally have a certain length, the first spring 22 which plays a major role in the impact process has a sufficient length of compression stroke, and the cutter head 31 also has a sufficient length of impact stroke, so as to meet the impact force required for cutting ice, in order to make the connecting columns 322 move up and down while keeping parallel to the axis of the guide column 21, so as to completely transmit the impact force to the cutter head 31 and avoid unnecessary loss, the connecting piece 32 further comprises a pair of sleeves 323, the axial direction of the sleeves 323 is parallel to the axial direction of the guide column 21, the sleeves 323 are fixedly connected to the rack and penetrate the inner and outer surfaces of the top of the rack 1, and the bottom end of the sleeve 323 extends into the installation cavity 10; the connecting columns 322 are correspondingly slidably arranged in the sleeves 323.

[0057] Further, as shown in Figure 1 and Figure 2 The tip of the cutter head 31 is serrated, so as to enhance the cutting ability of the cutter head 31, and the serrated cutter tip can reduce impact and wear and prolong the service life of the cutter head 31.

[0059] In particular, in the description of the present application, it should be understood that the term "airborne" used in the present application means that the deicing robot 1000 is designed to be carried on a certain carrier, usually an aircraft such as a drone or other flight equipment, for performing a deicing task, that is, the deicing robot 1000 can be launched and recovered based on a drone.

[0060] Based on the above technical solution, by setting up the robot body 200 on the ground wire of the transmission line, the impact ice cutting device 100 is used to impact and cut off 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 the 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 overlapping portion 4412 is located above the overlapping 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 downward by the transmission shaft 423, so that the overlapping portion 4412 is engaged with the overlapping 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 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 will be 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 will transmit the elastic force to the cutter head 31, and the cutter head 31 will impact upward, and the tip of the top of the cutter head 31 will rush toward the ice layer to cut the ice layer.

[0063] After the cutter head 31 cuts the ice layer, the drive motor 41 is controlled to reverse, and the transmission shaft 423 is driven to rotate through 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 portion 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.

[0064] In summary, an embodiment of the present invention provides an impact ice cutting device 100, which includes a frame 1, a power storage component 2, an ice cutting component 3 and a power component 4; the drive motor 41 is driven by the transmission mechanism 42 to drive the transmission platform 43 to move between the power storage position and the impact position relative to the frame 1 in the vertical direction, and when the transmission platform 43 is located at the power storage position, the transmission member 441 is engaged with the mobile platform 23 under the action of the second spring 442; and when the transmission platform 43 moves downward from the power storage position, the transmission member 441 drives the transmission platform 43 to move between the power storage position and the impact position.
