Technical Field
[0001] The invention relates to the technical field of deicing of transmission lines, in particular to an elastic energy storage type mechanical deicing device. Background Art
[0002] In the power industry, overhead transmission lines play the role of transmitting electricity generated by power stations to various electricity users. It is obvious that the stable operation of overhead transmission lines plays a vital role in the stability of users' electricity consumption, so it is necessary to regularly inspect and maintain overhead transmission lines. Especially in the severe winter and early spring seasons in Yuxi Huaning, Tonghai and Chengjiang, rime and rime often occur, which makes most of the overhead transmission lines in the area covered with a large amount of ice. If the ice on these transmission lines is not removed in time, as the ice covering the transmission lines becomes thicker, these overhead transmission lines will sag and dance, and even cause the overhead transmission lines to break and the poles to fall, which indirectly affects the stability of electricity consumption for various electricity users.
[0003] In response to the above situation where the overhead transmission lines are covered with ice, the existing technology is to use more complex thermal ice-melting technology, complex mechanical deicing equipment and gunpowder detonation to generate high-pressure gas to drive the piston to move instantly (a portable mechanical deicing device DAC developed by the Power Research Institute of Hydro-Quebec, Canada) for deicing. However, this complex thermal ice-melting technology, complex mechanical deicing equipment and gunpowder detonation to generate high-pressure gas to drive the piston to move instantly, although it can also remove ice covering the overhead transmission lines, the complex thermal ice-melting technology and complex mechanical deicing equipment have high manufacturing and maintenance costs, and a large amount of maintenance fees are required every year. As for the deicing method of using gunpowder detonation to generate high-pressure gas to drive the piston to move instantly, there is a high safety risk.

[0009] Furthermore, the outer wall of the ice-breaking roller has an ice-breaking cone group, and there are at least five groups of ice-breaking cone groups distributed along the circumference of the ice-breaking roller. Each ice-breaking cone group has at least eight ice-breaking cones, and the eight ice-breaking cones are distributed along the radial direction of the ice-breaking roller.
[0010] Furthermore, the elastic vibration component includes a protective box, a vibration spring, a spring release toggle plate and a toggle rod; the outer wall of the protective box is connected to the outer wall of the connecting plate, the inner wall of the protective box is connected to one end of the vibration spring, the other end of the vibration spring is abutted against the side wall of the spring release toggle plate, and the two ends of the spring release toggle plate are respectively rotatably connected to the inner wall of the protective box through a second rotating shaft, one of the second rotating shafts connected to the spring release toggle plate is also connected to one end of the toggle rod outside the protective box, the other end of the toggle rod is limitedly engaged with the lateral moving mechanism, and the middle part of the toggle rod is connected to one end of a traction rope used to release the energy stored in the vibration spring.
[0011] Furthermore, the transverse moving mechanism includes a limit frame, a transverse moving plate, a second motor and a moving unit; the limit slot on the limit frame is clamped with the toggle rod, one end of the limit frame is connected to the side wall of the transverse moving plate, one end of the transverse moving plate is connected to the outer wall of the protective box, and the other end of the transverse moving plate is embedded with a second motor, and the second motor is slidably connected to the side of the bracket through the moving unit.
[0012] Furthermore, when the toggle rod is engaged with the limit groove on the limit frame, the vibration spring in the protective box is in a compressed state; when the toggle rod is not engaged with or disengaged from the limit groove on the limit frame, the vibration spring in the protective box is in a released state.

[0014] Furthermore, limit protrusions are respectively arranged at both ends of the rack, the two limit protrusions are matched with the gear for limiting, and between the two limit protrusions is a tooth portion where the rack and the gear are meshed.
[0015] Furthermore, it also includes an elastic buffer component, which includes a vertical plate, a buffer cushion sleeve and a connecting strip.

At this time, the elastic vibration component vibrates by releasing elastic potential energy, and the vibrating elastic vibration component then drives the ice-covered transmission line in contact with the ice-breaking end of the ice-breaking roller mechanism to vibrate, thereby greatly reducing the adhesion of the ice covering the transmission line. In this case, the lateral moving mechanism drives the rotating ice-breaking end in the ice-breaking roller mechanism along the bracket to move back and forth horizontally on the ice-covered transmission line, thereby crushing and breaking the ice covering the transmission line to remove the ice covering the transmission line.

[0019] 1. The present invention integrates a bracket, a lateral movement mechanism, an elastic vibration component and an ice-breaking roller mechanism into an elastic energy storage mechanical de-icing device. When de-icing a transmission line covered with ice, the vibration of the elastic vibration component first vibrates the ice covered on the transmission line through the ice-breaking roller mechanism, so that the adhesion between the ice and the transmission line is greatly reduced. In this case, the ice-breaking roller mechanism then rotates and crushes the ice with reduced adhesion to remove it. In this way, the de-icing is combined by reducing the adhesion between the ice and the transmission line and rotating and crushing the ice with reduced adhesion through the ice-breaking roller mechanism. Not only is the de-icing effect good, but the mechanical structure involved in this de-icing method is also simple and easy to operate. It does not involve thermal ice-melting technology and the use of complex mechanical structures, which indirectly reduces the manufacturing and maintenance costs, making the device more economical and practical, so as to solve the problem of high manufacturing and maintenance costs caused by the existing de-icing of ice on the transmission line using thermal ice-melting technology and the use of complex mechanical structures.
[0020] 2. The elastic energy storage mechanical deicing device of the present invention, during the process of deicing ice on the transmission lines, only reduces the adhesion of ice to the transmission lines and uses an ice-breaking roller mechanism to rotate and break the ice with reduced adhesion to perform deicing. It does not use fire to de-ice as in traditional deicing mechanical equipment, which not only improves the safety of operation, but also reduces the risk of burning out the transmission lines.
[0021] 3. The elastic energy storage mechanical deicing device of the present invention has a simple and intuitive operation process, which not only facilitates the rapid response and operation of on-site workers, but also improves the deicing efficiency and reduces the risk of misoperation and accidents caused by complex operations.

DETAILED DESCRIPTION
[0036] like Figure 1-12 In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0037] Example
[0038] In the case where overhead transmission lines are covered with ice, the existing technology uses relatively complex thermal ice-melting technology, complex mechanical deicing equipment and gunpowder detonation to generate high-pressure gas to drive the piston to move instantly (a portable mechanical deicing device DAC developed by the Power Research Institute of Hydro-Quebec, Canada) to remove the ice. However, although this complex thermal ice-melting technology, complex mechanical deicing equipment and gunpowder detonation to generate high-pressure gas to drive the piston to move instantly can also remove ice covering the overhead transmission lines, the complex thermal ice-melting technology and complex mechanical deicing equipment have high manufacturing and maintenance costs, and a large amount of maintenance fees are required every year. As for the deicing method of using gunpowder detonation to generate high-pressure gas to drive the piston to move instantly, there is a high safety risk.
[0039] Therefore, the present application designs an elastic energy storage type mechanical deicing device to solve the problem of high manufacturing and maintenance costs caused by the existing deicing of transmission lines using thermal ice melting technology and complex mechanical structures.
[0040] For details, please refer to Figure 1 The elastic energy storage type mechanical deicing device comprises a bracket 1, a lateral moving mechanism 2, an elastic vibration component 3 and an ice-breaking roller mechanism 4; the top of the bracket 1 is connected to the bottom of the UAV through a lifting rope, the side of the bracket 1 is slidingly connected to the side of the lateral moving mechanism 2, the moving end of the lateral moving mechanism 2 is connected to the outer wall of the elastic vibration component 3, the inner wall of the elastic vibration component 3 is connected to the fixed end of the ice-breaking roller mechanism 4, and the area between the ice-breaking end of the ice-breaking roller mechanism 4 and the bottom of the bracket 1 is an area 5 for wire ice breaking.
[0041] In actual use, when de-icing the transmission line covered with ice, a drone is used to lift the elastic energy storage mechanical de-icing device composed of the bracket 1, the lateral moving mechanism 2, the elastic vibration component 3 and the ice-breaking roller mechanism 4 to the vicinity of the ice-covered transmission line, and the ice-covered transmission line is stuck in the conductor ice-breaking area 5 between the ice-breaking end of the ice-breaking roller mechanism 4 and the bottom of the bracket 1. At this time, the elastic vibration component 3 vibrates by releasing elastic potential energy, and the vibrating elastic vibration component 3 then drives the ice-covered transmission line in contact with the ice-breaking end of the ice-breaking roller mechanism 4 to vibrate, so that the adhesion of the ice covered on the transmission line is greatly reduced. In this case, the lateral moving mechanism 2 drives the rotating ice-breaking end of the ice-breaking roller mechanism 4 along the bracket to move back and forth horizontally on the ice-covered transmission line, so as to break the ice covered on the transmission line and remove the ice covered on the transmission line.
[0042] It should be noted that the UAV is a multi-rotor UAV with a camera and a load capacity of more than 10 kg. The UAV is existing technology and has not been designed or improved, so its structure will not be described in detail.
[0043] See also Figure 2 The ice-breaking roller mechanism 4 for finally breaking the ice covering the transmission line comprises a connecting plate 6, a driving gear 7, a driven gear 8 and an ice-breaking roller 9; wherein the connecting plate 6 is used as a base for assembling the driving gear 7, the driven gear 8 and the ice-breaking roller 9 on the one hand; on the other hand, it is used to connect with the elastic vibration component 3 to transmit the vibration of the elastic vibration component 3 to the ice-breaking roller 9; the driving gear 7 is used to drive the ice-breaking roller 9 to rotate circumferentially through the driven gear 8; the ice-breaking roller 9 is used to break the ice covering the transmission line to remove the ice covering the transmission line.
[0044] Specifically, the outer wall of the connecting plate 6 is connected to the side wall of the elastic vibration component 3, and a first motor 10 is embedded on the connecting plate 6. The driving gear 7 on the output shaft of the first motor 10 is meshed with the driven gear 8, and the driven gear 8 is sleeved on the rotating shaft 11 which is rotatably connected to the inner wall of the connecting plate 6, and one end of the rotating shaft 11 away from the inner wall of the connecting plate 6 is connected to the end of the ice-breaking roller 9.
[0045] In actual use, the ice-covered transmission line is connected to the conductor ice-breaking area 5 between the middle ice-breaking roller 9 and the bottom of the bracket 1 of the ice-covered transmission line. When the ice-breaking roller mechanism 4 breaks the ice with reduced adhesion on the transmission line, the first motor 10 first drives the driving gear 7 to start rotating, and the rotating driving gear 7 then drives the ice-breaking roller 9 to rotate circumferentially through the driven gear 8. The circumferentially rotating ice-breaking roller 9 rotates and breaks the ice coated on the transmission line, thereby completing the process of the ice-breaking roller mechanism 4 finally removing the ice on the coated transmission line.
[0046] See also Figure 2 In order to improve the effect of the ice-breaking roller 9 on removing ice from the transmission line, the outer wall of the ice-breaking roller 9 also has an ice-breaking cone group 12. The ice-breaking cone group 12 has at least five groups of ice-breaking cone groups 12 distributed evenly along the circumference of the ice-breaking roller 9. Each ice-breaking cone group 12 has at least eight ice-breaking cones, and the eight ice-breaking cones are distributed evenly along the radial direction of the ice-breaking roller.
[0047] In actual use, when the ice-breaking roller 9 breaks and removes the ice covering the transmission line, since the outer wall of the breaking roller 9 is provided with an ice-breaking cone with a small force contact area with the ice covering the transmission line, the ice covering the transmission line can be easily broken in a short time, thereby further improving the de-icing efficiency of the device.
[0048] It should be noted that the end of the ice-breaking cone 12 that contacts the ice covering the transmission line has a smooth transition and is not a sharp end. That is, when the crushing roller 9 drives the crushing cone to break the ice covering the transmission line, the ice-breaking cone 12 will not easily scratch the protective skin on the outside of the transmission line.
[0049] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The elastic vibration component 3 for reducing the adhesion between the ice coated on the transmission line and the transmission line and improving the effect of the ice-breaking roller mechanism 4 on breaking the ice coated on the transmission line includes a protective box 13, a vibration spring 14, a spring release toggle plate 15 and a toggle rod 16; wherein the protective box 13 is used as a base for installing the vibration spring 14, the spring release toggle plate 15 and the toggle rod 16; the vibration spring 14 is used to make the protective box 13 vibrate when restoring the deformation, and indirectly drive the ice-breaking roller mechanism 4 connected to the protective box 13 to vibrate; the spring release toggle plate 15 and the toggle rod 16 cooperate to release the compressed vibration spring 14 in the protective box 13, so that the vibration spring 14 restores the deformation and vibrates.
[0050] Specifically, the outer wall of the protective box 13 is connected to the outer wall of the connecting plate 6, the inner wall of the protective box 13 is connected to one end of the vibration spring 14, and the other end of the vibration spring 14 abuts against the side wall of the spring release toggle plate 15. The two ends of the spring release toggle plate 15 are respectively rotatably connected to the inner wall of the protective box 13 through the second rotating shaft 32, and one of the second rotating shafts 32 connected to the spring release toggle plate 15 is also connected to one end of the toggle rod 16 outside the protective box 13, and the other end of the toggle rod 16 is limitedly engaged with the lateral moving mechanism 2, and the middle part of the toggle rod 16 is connected to one end of a traction rope used to release the energy stored in the vibration spring.
[0051] In actual use, before the ice-breaking roller mechanism 4 removes the ice covered on the transmission line, when the elastic vibration component 3 is used to vibrate the ice covered on the transmission line through the ice-breaking roller mechanism 4, first hold one end of the traction rope and pull it to one side to disengage the toggle rod 16 connected to the other end of the traction rope from the limiting part of the lateral movement mechanism 2, and the compressed vibration spring 14 will no longer be restricted by the spring release toggle plate 15 and restore its deformation. When the vibration spring 14 restores its deformation, it will hit the inner wall of the protection box 13 and cause vibration, which indirectly causes the protection box 13 to vibrate and the ice-breaking roller mechanism 4 connected to the protection box 13 to vibrate. The vibrating ice-breaking roller mechanism 4 vibrates the ice covered on the transmission line to reduce the adhesion between the ice covered on the transmission line and the transmission line, thereby improving the ice-breaking roller mechanism 4's effect of crushing the ice covered on the transmission line.
[0052] It should be noted that the bottom plate of the protective box 13 and the side wall of the protective box are detachably connected. If the vibration spring 14 needs to be restored to a compressed state to continue working after recovering its deformation, the bottom plate of the protective box 13 can be removed, and then the vibration spring 14 can be manually compressed, and the toggle rod 16 can be used to limit the engagement with the horizontal moving mechanism 2, so that the spring release toggle plate 15 can abut against the compressed vibration spring 14.
[0053] It should be noted that the original length of the vibration spring 14 is much greater than the length of the protection box 13, so that the spring can hit the inner wall of the protection box 13 to generate vibration when restoring its deformation.
[0054] It should be noted that a certain distance is left between the spring release toggle plate 15 and the inner bottom of the protection box 13 to prevent the spring release toggle plate 15 from interfering with the inner bottom of the protection box 13 .
[0055] See also Figure 3 , Figure 6 and Figure 7 In the process of the ice-breaking roller 9 in the ice-breaking roller mechanism 4 rotating to remove the ice covered on the transmission line, the lateral moving mechanism 2 used to increase the de-icing area of the ice-breaking roller mechanism 4 and to limit the toggle rod 16 includes a limit frame 17, a lateral moving plate 18, a second motor 19 and a moving unit 20; wherein, the limit frame 17 is used to limit the toggle rod 16 so that the vibration spring 14 in the protective box 13 is in a compressed state; the lateral moving plate 18 is used as a base for installing the limit frame 17, the second motor 19 and the moving unit 20; the second motor 19 is used to drive the moving unit 20 to move laterally along the bracket 1 with the ice-breaking roller mechanism 4 and the elastic vibration component 3, so as to crush the ice covering most areas of the transmission line through the moving ice-breaking roller mechanism 4.
[0056] Specifically, the limit groove 21 provided on the limit frame 17 is engaged with the toggle rod 16, that is, when the toggle rod 15 is engaged with the limit groove 21 provided on the limit frame 17, the vibration spring 14 in the protective box 13 is in a compressed state; when the toggle rod 15 is not engaged with or disengaged from the limit groove 21 provided on the limit frame 17, the vibration spring 14 in the protective box is in a released state.
[0057] The above is the limiting cooperation relationship between the toggle rod 16 and the specific components in the transverse moving mechanism 2, and the following is the connection relationship of the transverse moving mechanism 2, that is, one end of the limiting frame 17 is connected to the side wall of the transverse moving plate 18, one end of the transverse moving plate 18 is connected to the outer wall of the protective box 13, and the other end of the transverse moving plate 18 is embedded with a second motor 19, and the second motor 19 is slidably connected to the side of the bracket 1 through the moving unit 20.
[0058] In actual use, when the lateral moving mechanism 2 drives the ice-breaking roller mechanism 4 to break the ice covering other areas on the transmission line, the second motor 19 arranged on the lateral moving plate 18 is first powered on and rotated, and the rotating second motor 19 drives the ice-breaking roller mechanism 4 to move laterally along the bracket 1 through the moving unit 20. During the lateral movement process, the ice-breaking roller 9 in the ice-breaking roller mechanism 4 in a working state breaks and removes the ice covering most areas on the transmission line.
[0059] See also Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The moving unit 20 of the lateral moving mechanism 2 includes a moving sleeve 31, a gear 22 and a rack 23; wherein the moving sleeve 31 is used for sliding engagement with the bracket 1 on one hand, and is used as a base for installing the gear 22 on the other hand; the gear 22 is driven by the second motor 19 to mesh with the rack 23 on the bracket 1.
[0060] Specifically, the output shaft of the second motor 19 is rotationally connected to the movable sleeve 31 and the side wall of the transverse movable plate 18 respectively, the gear 22 on the output shaft of the second motor 19 located in the movable sleeve 31 is meshed with the rack 23 on the side wall of the bracket 1, and the inner top wall of the movable sleeve 31 and the slide groove 24 opened on the inner top wall are slidably connected with the slide bars on the top wall and bottom wall of the bracket 1.
[0061] In actual use, when the moving unit 20 is driven by the second motor 19, the second motor 19 first drives the gear 22 to rotate, and the rotating gear 22 moves laterally along the rack 23 on the side of the bracket 1 to drive the lateral moving plate 18 connected to the second motor 19 and the elastic vibration component 3 connected to the lateral moving plate 18, and the ice breaking roller mechanism 4 connected to the elastic vibration component 3.
[0062] The lateral movement is completed, thereby completing the process in which the lateral movement mechanism 2 drives the elastic vibration component 3 and the ice-breaking roller mechanism 4 to move lateraly.
[0063] See also Figure 8 In order to prevent the gear 22 and the rack 23 from derailing, limit protrusions 25 are respectively provided at both ends of the rack 23. The two limit protrusions 25 are limitedly matched with the gear 22, and the tooth part between the two limit protrusions 25 is the tooth part where the rack 23 and the gear 22 are meshed.
[0064] In actual use, when the gear 22 is driven by the second motor 19, since limiting protrusions 25 are respectively provided at both ends of the rack 23, when the gear 22 moves to the position of the limiting protrusions 25 at both ends of the gear 22, the limiting protrusions 25 prevent the gear 22 from continuing to move, so as to limit the movement of the gear 22 and prevent the gear 22 and the rack 23 from derailing.
[0065] See also Figure 1 and Fig.11When the elastic vibration component 3 causes the lateral moving mechanism 2 and the ice-breaking roller mechanism 4 to vibrate, in order to avoid excessive vibration of the lateral moving mechanism 2 and the ice-breaking roller mechanism 4, the elastic energy storage mechanical deicing device also includes an elastic buffer 26, and the elastic buffer 26 includes a vertical plate 27, a buffer sleeve 28 and a connecting strip 29; wherein the vertical plate 27 is used to connect with the protective box 13 in the elastic vibration component 3 on the one hand, and to connect with the columnar buffer sleeve 28 on the other hand; the connecting strip 29 is used to connect with the buffer sleeve 28 on the one hand, and to connect with the columnar buffer sleeve 28 through the connecting strip 29 on the other hand; the buffer sleeve 28 is used to buffer the vibration of the elastic vibration component 3, thereby indirectly reducing the vibration of the ice-breaking roller mechanism 4 connected to the elastic vibration component 3.
[0066] Specifically, the bottom of the vertical plate 27 is connected to the top of the protective box 13, the inner wall of the vertical plate 27 is connected to one end of the buffer cushion cover 28, the other end of the buffer cushion cover 28 is connected to one end of the connecting strip 29, and the other end of the connecting strip 29 is connected to the outer wall of the first motor 10.
[0067] In actual use, when the elastic vibration component 3 causes the lateral moving mechanism 2 and the ice-breaking roller mechanism 4 to vibrate significantly, the relatively large vibrations preferentially act on the buffer sleeve 28 through the vertical plate 27 connected to the elastic vibration component 3 and the connecting strip 29 connected to the first motor 10. The buffer sleeve 28 reduces the vibration amplitude by deformation to avoid the lateral moving mechanism 2 and the ice-breaking roller mechanism 4 from vibrating significantly.
[0068] It should be noted that the elastic buffer 26 only reduces part of the vibration caused by the elastic vibration component 3, so that the lateral moving mechanism 2 and the ice-breaking roller mechanism 4 will not generate large-scale vibrations and affect normal work. This does not conflict with the aforementioned use of the elastic vibration component 3 to vibrate the ice covering the transmission line through the ice-breaking roller mechanism 4 before the ice-breaking roller mechanism 4 removes the ice covering the transmission line.
[0069] See also Figure 1 and Fig.12 In order to connect the lifting rope to the bracket 1 and the UAV respectively, a lifting ear 30 is provided on the top of the bracket 1, one end of the lifting rope is connected to the lifting ear 30, and the other end of the lifting rope is connected to another lifting ear on the top of the UAV.
[0070] In actual use, when the elastic energy storage mechanical deicing device is hoisted near an ice-covered power transmission line by using a drone and a hoisting rope, the hoisting rope can be used to connect to another hoisting ear at the bottom of the drone and the hoisting ear 30 at the top of the bracket 1 respectively, so as to complete the process of connecting the elastic energy storage mechanical deicing device to the drone by using the hoisting rope.
[0071] The present application integrates a bracket 1, a lateral moving mechanism 2, an elastic vibration component 3 and an ice-breaking roller mechanism 4 into an elastic energy storage mechanical de-icing device. When de-icing a transmission line covered with ice, the vibration of the elastic vibration component 3 first vibrates the ice covering the transmission line through the ice-breaking roller mechanism 4, so that the adhesion between the ice and the transmission line is greatly reduced. In this case, the ice-breaking roller mechanism 4 then rotates and crushes the ice with reduced adhesion to remove it. In this way, the de-icing is combined by reducing the adhesion between the ice and the transmission line and rotating and crushing the ice with reduced adhesion through the ice-breaking roller mechanism 4. Not only is the de-icing effect good, but the mechanical structure involved in this de-icing method is also simple and easy to operate. It does not involve thermal ice-melting technology and does not use complex mechanical structures, which indirectly reduces the manufacturing and maintenance costs, making the device more economical and practical.
