Description

Technical Field

[0001] The present application relates to the field of cable installation and maintenance, and in particular to a snow and ice removal device for power tower cables. Background Art

[0002] As an important part of the power transmission system, power towers are often covered with ice and snow in winter. The accumulation of ice and snow not only increases the weight of cables, but may also cause line breakage or short circuit, seriously affecting the safe operation of the power grid.

[0003] At present, maintenance personnel of power systems usually need to conduct regular inspections and manually remove ice and snow from cables. This process is time-consuming, labor-intensive and has certain safety risks. In order to deal with the problem of ice and snow on power tower cables, common existing methods include manual snow removal and the use of chemical snow melting agents. Artificial snow removal mainly relies on ground workers or drones carrying tools to carry out operations. Although the operation is flexible, it is inefficient and difficult to implement in severe weather conditions. Chemical snow melting agents melt ice and snow by spraying specific chemicals. Although this method is fast and effective, the pollution caused by snow melting agents to the environment limits its widespread application. In addition, some automated snow removal equipment has gradually emerged. By placing snow removal equipment on cables and operating the snow removal equipment to remove snow from cables while moving along the length of the cables, automated snow removal is achieved. Compared with manual snow removal, the labor intensity of workers is greatly reduced and the snow removal efficiency is improved; compared with chemical snow melting agents, snow removal greatly reduces pollution to the environment.

[0004] However, because the snow removal equipment itself has a certain weight, when placing the snow removal equipment on the cables, it will undoubtedly increase the load on the cables. If the cables themselves have reached their load-bearing limit, the placement of the snow removal equipment will accelerate the breakage of the cables, seriously affecting the safe operation of the power grid. Summary of the invention

[0005] In order to achieve rapid snow removal from cables without increasing excessive load on the cables, the present application provides a snow and ice removal device for power tower cables.

[0006] The present application provides a snow and ice removal device for power tower cables, which adopts the following technical solution:

[0007] A snow and ice removal device for power tower cables, characterized by comprising:

[0008] There are two mounting seats, the two mounting seats are respectively used to be mounted on two adjacent power tower poles, the mounting seats include a base, and the base is provided with a positioning groove for inserting the power tower pole;

[0009] A support rod, mounted between the two mounting seats;

[0010] A snow and ice removal mechanism, slidably connected to the support rod;

[0011] A self-driving mechanism is installed on the support rod and is used to drive the snow and ice removal mechanism to slide along the length direction of the support rod, including a first sliding seat slidably connected to the support rod, a second sliding seat slidably connected to the support rod, a clamping assembly for fixing / releasing the position of the first sliding seat on the support rod and simultaneously releasing / fixing the position of the second sliding seat on the support rod, and a linear driving assembly installed between the first sliding seat and the second sliding seat for adjusting the distance between the first sliding seat and the second sliding seat.

[0012] By adopting the above technical solution, the design of the mounting seat enables the device to be stably installed on the adjacent power tower poles, ensuring the stability of the entire device. The support rod connects the two mounting seats, providing a stable support structure on which the snow and ice removal mechanism can slide. The snow and ice removal mechanism is slidably connected to the support rod and can move freely along the support rod to achieve snow and ice removal within the entire cable range. Because the gravity of the entire snow and ice removal mechanism acts on the power tower pole through the support rod, it does not increase the load-bearing capacity of the cable, and at the same time achieves rapid snow removal from the cable.

[0013] Optionally, the mounting base also includes a lifting cylinder fixed to the bottom of the positioning groove and a lifting plate fixed to the piston rod of the lifting cylinder. When the base is installed on the pole of the power tower, the side of the lifting plate away from the lifting cylinder abuts against the upper end of the pole of the power tower.

[0014] By adopting the above technical solution, the design of the lifting cylinder and the lifting plate can enable the lifting plate to abut against the upper end of the power tower pole when the mounting base is fixed on the power tower pole. When the lifting cylinder piston rod is extended, the base can be driven to rise to release the coordination between the base and the power tower pole.

[0015] Optionally, the mounting base also includes a driving motor fixedly connected to the lifting plate, the output shaft of the driving motor passes through the base, one end of the support rod is fixedly connected to the output shaft of one driving motor, and the other end of the support rod is slidably connected to the output shaft of another driving motor, and a mounting tube is fixedly connected to the output shaft of the driving motor slidably connected to the support rod, and the support rod is slidably connected in the mounting tube.

[0016] By adopting the above technical solution, after the base is lifted by the lifting cylinder, another driving motor can be used to drive the lifted base and the support rod to rotate 180 degrees, so that the entire snow and ice removal device is located between another power tower pole and the next power tower pole, so as to facilitate snow and ice removal work on the cables between the next power tower poles.

[0017] Optionally, the mounting seat also includes a clamping plate slidably connected to the inner wall of the mounting seat and a clamping drive assembly for driving the clamping plate to move radially. The clamping plate is an arc-shaped plate, and multiple clamping plates are provided, and the multiple clamping plates are spaced apart around the axis of the mounting seat.

[0018] By adopting the above technical solution, the mounting base can be firmly fixed on the pole of the power tower, thereby ensuring the stability of the entire device. Multiple arc-shaped plates are arranged at intervals around the axis of the mounting base, and the clamping force can be adjusted according to actual needs to adapt to poles of different diameters, thereby improving the applicability and safety of the device. In addition, the clamping drive assembly can drive the clamping plate to move radially, so as to quickly and easily complete the fixing work of the mounting base and the pole of the power tower, and the operation is more convenient.

[0019] Optionally, the driving assembly includes a plurality of threaded rods threadedly connected to the side wall of the mounting seat, the plurality of threaded rods are arranged in a one-to-one correspondence with the plurality of clamping plates, one end of the threaded rod located in the positioning groove is rotatably connected to the clamping plate, each of the threaded rods is slidably connected to a driving gear, a gear ring is rotatably connected to the side wall of the mounting seat for driving the plurality of driving gears to rotate simultaneously, and a rotating motor is fixed to the side wall of the mounting seat for driving the gear ring to rotate.

[0020] By adopting the above technical solution, multiple threaded rods in the driving assembly are arranged in one-to-one correspondence with multiple clamping plates, so that the clamping plates can be evenly distributed and tightly fit the tower surface, thereby ensuring the stability of the mounting seat. In addition, the rotating motor drives the gear ring to rotate, and then synchronously drives all the driving gears to rotate, so that each threaded rod moves at the same time, ensuring the operational consistency of the entire structure and improving the installation efficiency.

[0021] Optionally, the clamping assembly includes a first clamping plate slidably connected to the first sliding seat, a second clamping plate slidably connected to the second sliding seat, a first driving member for driving the first clamping plate to slide, and a second driving member for driving the second clamping plate to slide.

[0022] Optionally, the first driving member includes a first cam rotatably connected in the first sliding seat and a first motor fixed on the first sliding seat for driving the first cam to rotate; the second driving member includes a second cam rotatably connected in the second sliding seat and a second motor fixed on the second sliding seat for driving the second cam to rotate.

[0023] By adopting the above technical solution, the first motor drives the first cam to rotate, thereby pushing the first clamping plate to slide, and realizes the clamping or loosening of the first sliding seat; similarly, the second motor drives the second cam to rotate, pushing the second clamping plate to slide, and realizes the clamping or loosening of the second sliding seat. When the first sliding seat is clamped and the second sliding seat is loosened, the distance between the first sliding seat and the second sliding seat is increased by adjusting the linear drive component, and the second sliding seat can be driven to slide on the support rod in the direction of the second sliding seat; then when the second sliding seat is clamped and the first sliding seat is loosened, the distance between the first sliding seat and the second sliding seat is reduced by adjusting the linear drive component, and the first sliding seat can be driven to slide in the direction of the second sliding seat, and the cycle is repeated in sequence, so that the snow and ice removal mechanism can be driven to move along the length direction of the support rod as a whole, and the snow and ice removal mechanism can be self-driven.

[0024] Optionally, the snow and ice removal mechanism includes a support frame fixedly connected to the first sliding seat, a first mounting frame detachably connected to the support frame, and a snow removal barrel fixed in the first mounting frame, a sliding entrance for cable embedding is provided on the side of the snow removal barrel away from the support frame, and snow removal knives are fixedly connected to both ends of the snow removal barrel.

[0025] By adopting the above technical solution, the design of the support frame enables the snow removal barrel to be firmly installed on the first sliding seat, ensuring its stability and reliability. The detachable design of the first installation frame facilitates the adjustment of the installation position and installation quantity of the first installation frame as needed, so as to adapt to the removal needs of cables of different numbers and different spacings, thereby increasing the scope of use of the device. The sliding entrance on the snow removal barrel facilitates the entry of the cables, and the snow removal blade fixed to one end of the snow removal barrel can efficiently cut and remove ice and snow on the surface of the cables during the snow removal process.

[0026] Optionally, the snow and ice removal mechanism also includes a second mounting frame detachably connected to the support frame, a deicing motor fixed in the second mounting frame, a deicing cam fixed on the output shaft of the deicing motor, and a striking hammer slidably connected in the second mounting frame, the striking hammer abuts against the deicing cam, and a return spring is fixed between the striking hammer and the second mounting frame.

[0027] By adopting the above technical solution, the de-icing motor drives the de-icing cam to rotate through the output shaft, so that the striking hammer repeatedly hits the cable surface under the abutment of the de-icing cam and the tension of the return spring, thereby destroying and shattering the hard ice layer attached thereto.

[0028] Optionally, the support frame includes a first support plate fixedly connected to the first sliding seat, a telescopic cylinder fixedly connected to the first support plate, and a second support plate fixedly connected to an end of the telescopic cylinder away from the first support plate, and the first support plate is slidably connected to the second sliding seat.

[0029] By adopting the above technical solution, the setting of the telescopic cylinder can facilitate the adjustment of the vertical positions of the first installation frame and the second installation frame, so that the cable can smoothly slide into the snow removal barrel or slide out of the snow removal barrel, and the operation is more flexible.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] By slidably connecting the snow and ice removal mechanism to the support rod and using the self-driving mechanism to drive it to slide along the length direction of the support rod, efficient and automatic snow removal of the cable is achieved, which significantly improves the snow removal efficiency and reduces the labor intensity of manual labor.

[0032] The design of the mounting base enables the device to be firmly fixed on the pole of the power tower, avoiding the increase of cable burden due to the weight of the device itself and ensuring the safety of the cable;

[0033] The self-driving mechanism adopts a linear driving assembly between the first sliding seat and the second sliding seat, which can achieve precise control without applying additional load, thereby ensuring the smoothness and reliability of the snow removal process.

[0041] The following is combined with Figure 1-6 This application is described in further detail.

[0042] The present application embodiment discloses a snow and ice removal device for power tower cables. Figure 1 The snow and ice removal device for power tower cables comprises two mounting seats 1 for mounting on two adjacent power tower poles, a support rod 2 connected between the two mounting seats 1, a snow and ice removal mechanism 3 slidably connected to the support rod 2, and a self-driving mechanism 4 for driving the snow and ice removal mechanism 3 to slide on the support rod 2. When in use, the two mounting seats 1 can be hoisted to the poles of two adjacent power towers by using a drone, etc. At this time, the length direction of the support rod 2 is consistent with the length direction of the cable, and the self-driving mechanism 4 can drive the snow and ice removal mechanism 3 to slide along the length direction of the support rod 2, thereby realizing automatic snow and ice removal work for the cable.

[0043] Reference Figure 2 and Figure 3 The mounting base 1 includes a base 11, on which a positioning groove 111 for inserting the pole of the power tower is opened, so that when the base 11 is lifted to the top of the pole of the power tower by an unmanned aerial vehicle, the base 11 is directly driven down, so that the pole of the power tower can be inserted into the positioning groove 111, and the installation of the base 11 is completed.

[0044] At the same time, in order to make the position of the base 11 on the power tower pole more firmly fixed, the mounting base 1 also includes a clamping plate 12 slidably connected to the inner wall of the mounting base 1 and a clamping drive assembly 13 for driving the clamping plate 12 to move radially, so that when the base 11 is placed on the power tower pole, the clamping drive assembly 13 can directly drive the clamping plate 12 to move radially, thereby clamping the power tower pole.

[0045] Reference Figure 3 and Figure 4 The clamping plate 12 is an arc-shaped plate, and a plurality of the clamping plates 12 are arranged at intervals around the axis of the mounting seat 1. The plurality of clamping plates 12 can be firmly clamped around the pole of the power tower. The clamping drive assembly 13 includes a plurality of threaded rods 131 threadedly connected to the side wall of the base 11. The plurality of threaded rods 131 are arranged one-to-one with the plurality of clamping plates 12. One end of the threaded rod 131 is located in the positioning groove 111, and the end of the threaded rod 131 located in the positioning groove 111 is rotatably connected to the clamping plate 12. The other end of the threaded rod 131 extends out of the base 11 and is exposed to the outside. A driving gear 132 is slidably connected to the end of the threaded rod 131 exposed to the outside. There is a driving gear 132 between the base 11 and the driving gear 132. A connecting tube 133 is provided in the middle, the connecting tube 133 is sleeved on the threaded rod 131 and the connecting tube 133 is fixedly connected to the base 11, and the driving gear 132 is rotatably connected to the connecting tube 133. The driving gear 132 and the threaded rod 131 are connected by a key, so that when the driving gear 132 rotates, the threaded rod 131 can be driven to rotate. Since the threaded rod 131 is threadedly connected to the base 11, the threaded rod 131 will drive the clamping plate 12 to approach or move away from the axis of the base 11 when rotating.

[0046] Among them, a gear ring 134 is rotatably connected to the outer wall of the base 11, and one side of the gear ring 134 has teeth. The gear ring 134 is simultaneously engaged with the driving gears 132 on the multiple threaded rods 131. At the same time, a rotating motor 135 is fixedly connected to the outer wall of the base 11 for driving the gear ring 134 to rotate, and power is transmitted between the rotating motor 135 and the gear ring 134 through a gear set.

[0047] It is understandable that when the threaded rod 131 rotates, the abutting plate 12 will not rotate with the threaded rod 131 due to the limitation of the power tower pole. Of course, a telescopic rod for guiding the abutting plate 12 can also be provided between the base 11 and the abutting plate 12, one end of the telescopic rod is fixedly connected to the side wall of the positioning groove 111, and the other end of the telescopic rod is slidably connected to the outer wall of the abutting plate 12, and an auxiliary groove for the end of the abutting plate 12 to be embedded and slide is provided on the side wall of the abutting plate 12 along its circumferential direction, so that when the threaded rod 131 rotates, due to the limitation of the telescopic rod, the abutting plate 12 will not rotate with the threaded rod 131, and when the abutting plate 12 moves radially, the abutting plate 12 will drive the telescopic rod to extend and retract, and at this time the telescopic rod also slides in the auxiliary groove to avoid jamming.

[0048] Reference Figure 4 The mounting base 1 also includes a lifting cylinder 14 fixed to the bottom of the positioning groove 111 and a lifting plate 15 fixed to the piston rod of the lifting cylinder 14. The clamping assembly 43 is located on the side of the lifting plate 15 away from the bottom of the positioning groove 111, so that when the base 11 is installed on the pole of the power tower, the side of the lifting plate 15 away from the lifting cylinder 14 abuts against the upper end of the pole of the power tower.

[0049] The mounting base 1 also includes a driving motor 16 fixedly connected to the lifting plate 15, the output shaft of the driving motor 16 passes through the upper end of the base 11 and is exposed to the outside, one end of the support rod 2 is fixedly connected to the output shaft of the driving motor 16, the other end of the support rod 2 is slidably connected to the output shaft of another driving motor 16, and a mounting tube 17 is fixedly connected to the output shaft of the driving motor 16 slidably connected to the support rod 2, and the support rod 2 is slidably connected in the mounting tube 17. One end of the support rod 2 slidably connected to the output shaft of the driving motor 16 is threadedly connected with a fixing nut 19 to prevent the support rod 2 from sliding out of the mounting tube 17.

[0050] When the snow and ice removal of the cables between the poles of two adjacent power towers is completed, the piston rod of the lifting cylinder 14 can be directly controlled to extend. At this time, since the lifting plate 15 is in contact with the top of the power tower pole, the lifting cylinder 14 will drive the base 11 to slide upward until the base 11 is removed from the power tower pole. At this time, the output shaft of the driving motor 16 on the pole of the other power tower is controlled to rotate 180 degrees, and the mounting base 1 can be driven by the support rod 2 to rotate 180 degrees around the pole of the other power tower, so that the mounting base 1 is located on the upper side of the pole of the next power tower, and then the piston rod of the lifting cylinder 14 is controlled to retract, so that the base 11 can be installed on the pole of the next power tower, so that the snow and ice removal device can clean the ice and snow on the next section of the cable.

[0051] It is understandable that a magnet 18 is fixed to the base 11, and the drone can be adsorbed on the magnet 18 through the electromagnet 18 to drive the mounting seat 1 to be lifted to the top of the power tower pole. When the mounting seat 1 is driven to move to the next power tower pole by the driving motor 16, the electromagnet 18 on the drone can also be adsorbed on the magnet 18 of the moving mounting seat 1, thereby applying auxiliary lifting force to the mounting seat 1 to ensure the overall support strength of the support rod 2.

[0052] The sliding connection between the support rod 2 and one of the driving motors 16 enables a detachable connection between the snow and ice removal mechanism 3 and the support rod 2 as well as between the mounting base 1 and the support rod 2, making installation and disassembly very convenient.

[0053] Reference Figure 4 and Figure 5The self-driving mechanism 4 is installed on the support rod 2, and is used to drive the snow and ice removal mechanism 3 to slide along the length direction of the support rod 2, including a first sliding seat 41 slidably connected to the support rod 2, a second sliding seat 42 slidably connected to the support rod 2, a clamping assembly 43 for fixing / releasing the position of the first sliding seat 41 on the support rod 2 and for fixing / releasing the position of the second sliding seat 42 on the support rod 2, and a linear driving assembly 44 installed between the first sliding seat 41 and the second sliding seat 42 for adjusting the distance between the first sliding seat 41 and the second sliding seat 42. The linear driving assembly 44 can be selected from a cylinder, an electric push rod, etc.

[0054] The first sliding seat 41 and the second sliding seat 42 are both in the shape of a cuboid, and are provided with mounting holes 45 for cables to pass through.

[0055] The clamping assembly 43 includes a first clamping plate 431 slidably connected to the first sliding seat 41, a second clamping plate 432 slidably connected to the second sliding seat 42, a first driving member 433 for driving the first clamping plate 431 to slide, and a second driving member 434 for driving the second clamping plate 432 to slide. A fixed space for the support rod 2 to pass through is formed between the first clamping plate 431 and the upper side wall of the mounting hole 45 on the first sliding seat 41, and between the second clamping plate 432 and the upper side wall of the mounting hole 45 on the second sliding seat 42. The first driving member 433 can drive the first clamping plate 431 to slide in the mounting hole 45 of the first sliding seat 41 to fix the position of the first mounting seat 1 on the supporting rod 2, and the second driving member 434 can drive the second clamping plate 432 to slide in the mounting hole 45 of the second sliding seat 42 to fix the position of the second mounting seat 1 on the supporting rod 2.

[0056] Specifically, the first driving member 433 includes a first cam 4331 rotatably connected to the first sliding seat 41 and a first motor 4332 fixed to the first sliding seat 41 for driving the first cam 4331 to rotate; the second driving member 434 includes a second cam 4341 rotatably connected to the second sliding seat 42 and a second motor 4342 fixed to the second sliding seat 42 for driving the second cam 4341 to rotate. The first cam 4331 is located at the lower side of the first clamping plate 431 and abuts against the first clamping plate 431. When the first motor 4332 is started, the first motor 4332 will drive the first cam 4331 to rotate. When the long radius of the first cam 4331 abuts against the first clamping plate 431, the first clamping plate 431 will be driven to approach the fixed space, thereby clamping the support rod 2 between the first clamping plate 431 and the upper wall of the mounting hole 45 to fix the position of the first sliding seat 41 on the support rod 2. As the output shaft of the first motor 4332 continues to rotate, when the short diameter side of the first clamping plate 431 abuts against the first clamping plate 431, the first clamping plate 431 will slide away from the fixed space under the action of gravity, thereby releasing the fixed relationship between the first sliding seat 41 and the support rod 2. The second sliding seat 42 and the second clamping plate 432 are fixed in the same manner.

[0057] After the mounting seat 1 is mounted on the pole of the power tower, and the snow and ice removal mechanism 3 is clamped on the cable, the first clamping plate 431 is controlled to clamp the support rod 2 and the second clamping plate 432 is controlled to contact the support rod 2. At this time, the linear drive assembly 44 is controlled to extend, and the linear drive assembly 44 can push the second sliding seat 42 to slide on the support rod 2 so that the second sliding seat 42 moves forward; then the support rod 2 is clamped by the second clamping plate 432, and the clamping relationship of the first clamping plate 431 on the support rod 2 is released. At this time, the linear drive assembly 44 is controlled to shorten, and the linear drive assembly 44 can drive the first sliding seat 41 to slide in the direction of the second sliding seat 42, so as to drive the first sliding seat 41 to slide on the support rod 2. The cycle is repeated successively, so that the self-driving mechanism 4 itself can slide along the length direction of the support rod 2, thereby driving the snow and ice removal mechanism 3 installed on the self-driving mechanism 4 to slide along the length direction of the support rod 2, so as to clear the ice and snow on the cable.

[0058] Reference Figure 5 and Figure 6The snow and ice removal mechanism 3 includes a support frame 31 fixedly connected to a first sliding seat 41, a first installation frame 32 with a U-shaped cross section detachably connected to the support frame 31, and a snow removal barrel 33 fixedly connected to the first installation frame 32. The support frame 31 is slidably connected to the second sliding seat 42. A connecting strip 331 is fixedly connected between the side wall of the snow removal barrel 33 and the first installation frame 32, and the snow removal barrel 33 is fixedly connected to the first installation frame 32 through the connecting strip 331, and a sliding entrance 332 for the cable to slide into the snow removal barrel 33 is provided on the side of the snow removal barrel 33 away from the support frame 31. When in use, the first installation frame 32 is first controlled to be lifted to the top of the cable, and then the first installation frame 32 is controlled to be lowered, so that the cable can slide into the snow removal barrel 33 through the sliding entrance 332, thereby realizing the connection between the snow and ice removal mechanism 3 and the cable. Wherein, snow removal blades 333 are fixedly connected at both ends of the snow removal barrel 33, so that when the self-driving mechanism 4 drives the snow removal barrel 33 to move along the length direction of the support rod 2, the snow removal barrel 33 also slides along the length direction of the cable, so that the snow removal blades 333 remove the snow on the cable. The arrangement of the snow removal blades 333 at both ends of the snow removal barrel 33 enables the snow and ice on the cable between the two power tower poles to be removed when the snow removal and de-icing mechanism 3 moves in one direction along the support rod 2, and when the snow removal and de-icing device is transferred to between the other two power tower poles by driving the motor 16 and the lifting cylinder 14, the snow removal and de-icing mechanism 3 moves in the opposite direction along the support rod 2, so that the snow and ice between the other two power tower poles can be removed. The snow and ice removal work can be achieved by operating the snow removal and de-icing mechanism 3 to move in two directions.

[0059] In order to facilitate the cable to slide smoothly from the sliding entrance 332 into the snow removal barrel 33, a guide plate 334 is fixed on the outer wall of the snow removal barrel 33. Two guide plates 334 are provided. The two guide plates 334 are respectively located on opposite sides of the sliding entrance 332, and the distance between the two guide plates 334 gradually increases from the side close to the sliding entrance 332 to the side away from the sliding entrance 332, so as to guide the cable, so that the cable can slide smoothly into the snow removal barrel 33 along the guide plate 334. It can be understood that the width of the sliding entrance 332 is slightly smaller than the diameter of the cable, so that the cable can slide smoothly into the snow removal barrel 33 under the action of hard force, and the cable will not easily fall out of the snow removal barrel 33 after being located in the snow removal barrel 33. When the snow removal barrel 33 is operated to move upward, the cable can slide out of the snow removal barrel 33.

[0060] A heating wire may be installed in the snow removal cylinder 33 so that when the snow on the cable solidifies into ice, the ice can be heated, thereby reducing the connection strength of the ice and achieving ice removal.

[0061] Reference Figure 5 and Figure 6The snow and ice removal mechanism 3 further includes a second mounting frame 34 with a U-shaped cross section detachably connected to the support frame 31, a deicing motor 35 fixedly connected in the second mounting frame 34, a deicing cam 36 fixedly connected to the output shaft of the deicing motor 35, a striking hammer 37 slidably connected in the second mounting frame 34, and a return spring 38 fixedly connected between the striking hammer 37 and the second mounting frame 34. Under the pulling force of the return spring 38, the striking hammer 37 abuts against the deicing cam 36, and when the output shaft of the deicing motor 35 rotates, the deicing cam 36 will be driven to rotate, and the deicing cam 36 will slide back and forth in the second mounting frame 34 by abutting against the striking hammer 37 through the outer wall, so as to hit the cable.

[0062] There can be two second mounting frames 34, and the two second mounting frames 34 are respectively located on opposite sides of the first mounting frame 32, so that when removing ice and snow, the hammer 37 located on one side of the first mounting frame 32 first strikes the cable to knock off the impurities or snowflakes with weak condensation force on the cable, and then the snow removal knife 333 scrapes off the snow on the cable, and the small amount of snow adhering to the cable will be heated by the snow removal barrel 33 to melt the snow, thereby achieving snow removal. If there is ice on the cable, the hammer 37 located on one side of the first mounting frame 32 can reduce the connection strength between the ice and the cable, and if there is ice with weak connection, it will also be knocked off by the hammer 37, and then the snow removal barrel 33 heats the ice to melt the ice to reduce the overall connection strength of the ice, and finally the hammer 37 located on the other side of the first mounting frame 32 can apply a striking force to the ice, thereby knocking off the melted broken ice.

[0063] The distance between the second mounting frame 34 and the first mounting frame 32 is greater than 20 cm, so as to reduce the impact on normal snow removal work caused by the cable being hit by the hammer 37 and causing the cable to slip out of the snow removal barrel 33.

[0064] Reference Figure 5 The support frame 31 includes a first support plate 311 fixedly connected to the first sliding seat 41, a telescopic cylinder 312 fixedly connected to the side of the first support plate 311 away from the first sliding seat 41, and a second support plate 313 fixedly connected to the end of the telescopic cylinder 312 away from the first support plate 311, wherein the first support plate 311 is slidably connected to the second sliding seat 42, four telescopic cylinders 312 are provided, and the four telescopic cylinders 312 are respectively located at the four corners of the first support plate 311, and the first installation frame 32 and the second installation frame 34 are both installed on the second support plate 313. When the two mounting seats 1 are respectively installed on two adjacent tower poles of the power tower, the snow and ice removal mechanism 3 will be located directly above the cable, and the cable can be smoothly slid into the snow removal barrel 33 by controlling the extension of the piston rod of the telescopic cylinder 312.

[0065] Among them, three mutually parallel mounting strips 314 are fixedly connected to the second support plate 313, and the length direction of the mounting strips 314 is perpendicular to the length direction of the support rod 2. The first mounting frame 32 and the two second mounting frames 34 located on both sides of the first mounting frame 32 are respectively installed on the three mounting strips 314, and the first mounting frame 32 and each second mounting frame 34 are fixedly connected with auxiliary plates 39, which are fixed to the corresponding mounting strips 314 by bolts, and at the same time, a plurality of through holes 315 are spaced apart on each mounting strip 314 along its length direction, so as to facilitate the first mounting frame 32 and the second mounting frame 34 to be installed at a suitable position.

[0066] Reference Figure 4 A slider 421 with a T-shaped cross section is fixedly connected to the second sliding seat 42, and a slide groove 422 for the slider 421 to be embedded and slide is opened on the first support plate 311. Through the cooperation between the slider 421 and the slide groove 422, the second sliding seat 42 and the first support plate 311 are slidably connected.

[0067] Reference Figure 4 and Figure 5 In order to achieve snow and ice removal for multiple cables at the same time, multiple first installation frames 32 are arranged at intervals along the length direction of the installation bar 314, and multiple two first installation frames 32 are also arranged at intervals along the length direction of the corresponding installation bar 314, so that snow and ice removal for multiple cables can be achieved at the same time.

[0068] When in use, the staff installs a corresponding number of first mounting frames 32 and second mounting frames 34 at appropriate positions on the second support plate 313 according to the number of cables between two adjacent power tower poles to be cleaned and the distance between the two adjacent cables. This ensures that when the two mounting seats 1 are installed on two adjacent power tower poles, the first mounting frame 32 and the second mounting frame 34 are driven down by extending the piston rod of the telescopic cylinder 312, and multiple cables can slide smoothly into the corresponding snow removal barrel 33.

[0069] Of course, a linear drive assembly 44 that drives the snow and ice removal mechanism 3 to slide along the length direction of the mounting bar 314 can also be set between the first sliding seat 41 and the first support plate 311, so that the number of first mounting frames 32 and corresponding second mounting frames 34 can be set to one or more. After the corresponding number of cables are cleaned by the snow and ice removal mechanism 3, the piston rod of the telescopic cylinder 312 can be retracted to release the matching relationship between the first mounting frame 32 and the cables, and the first support plate 311 can be driven to move along the length direction of the mounting bar 314 as a whole by the linear drive assembly 44, so as to clean the remaining number of cables through the first mounting frame 32 and the second mounting frame 34. For example, when there are 6 cables, 6 first mounting frames 32 can be set, and 6 second mounting frames 34 located on both sides of the first mounting frame 32 are respectively set. At this time, the self-driving mechanism 4 drives the snow and ice removal mechanism 3 to slide once along the length direction of the support rod 2, and the cleaning work of all cables can be completed. Of course, two first mounting frames 32 and second mounting frames 34 located on both sides of the first mounting frame 32 can be provided, so that when the self-driving mechanism 4 drives the snow-removing and ice-removing mechanism 3 to slide once along the length direction of the support rod 2 to clean the two cables, the linear drive assembly 44 drives the snow-removing and ice-removing mechanism 3 to slide a set length in the vertical direction of the support rod 2, and then the self-driving mechanism 4 drives the snow-removing and ice-removing mechanism 3 to move in the opposite direction to clean the other two cables; the same method is used to clean the remaining two cables. When the cables between the poles of two adjacent power towers are cleaned, the snow-removing and ice-removing device can be moved between one of the poles of the power tower and the other pole of the power tower by lifting the cylinder 14 and driving the motor 16 to clean the ice and snow on the next section of the cable. The gravity of the entire snow-removing and ice-removing device acts on the pole of the power tower through the support rod 2 without increasing the load-bearing capacity of the cable too much, and can also realize automatic and rapid snow removal of the cable, making the operation more convenient and quick.

[0070] It is understandable that a battery can be installed on one or both of the two mounting seats 1 and / or on the snow and ice removal mechanism 3 to power the power tower cable snow and ice removal device and ensure the high-altitude automatic operation of the power tower cable snow and ice removal device.

[0071] Of course, the snow and ice removal mechanism can also use existing equipment on the market that can remove ice and snow from cables, as long as it is installed on the second support plate 313.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
