Description

Technical Field

[0001] This invention relates to the field of electrical engineering equipment technology, and in particular to a device for removing ice from power transmission lines used in electrical engineering. Background Technology

[0002] Electrical engineering is a core and key discipline in modern science and technology. Traditionally, electrical engineering is defined as the sum of disciplines related to the creation of electrical and electronic systems. However, with the rapid development of science and technology, the concept of electrical engineering has far exceeded the scope of the above definition. Today, electrical engineering encompasses almost all engineering activities related to electronics and photonics. Electrical engineering often requires the installation of cables and wires for power transmission. During use, transmission lines inevitably encounter low temperatures and icy weather, easily causing ice to form on the surface of railway transmission lines. Iced lines affect power supply, and excessively thick ice can even lead to line breakage. Therefore, it is necessary to remove the ice from the lines in a timely manner. The installation of power lines typically uses many suspension clamps for support. However, existing ice removal devices for transmission lines are inconvenient to bypass these clamps. Therefore, during the de-icing process, workers must climb the power tower to disassemble the device each time they encounter a clamp, bypass it, and then reinstall it on the power line. This operation is very cumbersome, requires workers to climb multiple times, and is even more dangerous. Therefore, we propose an ice removal device for transmission lines in electrical engineering.

[0011] As a preferred technical solution of the present invention: a slanted groove is provided on the inner wall of the front bottom of the semi-cylindrical base, and through holes are provided on the left and right side walls of the slanted groove, and flexible hoses are fixedly connected to the outer ports of the two through holes.

[0012] As a preferred embodiment of the present invention: a fixing ring is fixedly connected to the inner sidewall of both the semi-cylindrical cover and the semi-cylindrical base, and the lower fixing ring is located between the inclined groove and the driver.

[0013] As a preferred embodiment of the present invention: two support columns are provided in front of the fixed ring frame above. The top ends of the two support columns are fixedly connected to the inner side wall of the semi-cylindrical cover. A support plate is fixedly connected to the bottom end of the two support columns.

[0014] As a preferred technical solution of the present invention: a plurality of passive pinions are provided on the outer side of the driving large gear, and a crushing roller is provided at the center of each of the plurality of passive pinions. The top end of the central shaft of each crushing roller passes through the center of the corresponding passive pinion and extends rotatably into the bottom side wall of the support plate.

[0015] As a preferred embodiment of the present invention: the semi-cylindrical cover and the semi-cylindrical base are connected by two hinges, one end of the two hinges is fixedly connected to the lower end of the right side wall of the semi-cylindrical cover, and the other end of the two hinges is fixedly connected to the upper end of the right side wall of the semi-cylindrical base.

[0016] As a preferred technical solution of the present invention: half arrows are fixedly connected to the left and right sides of the bottom end of the deformable block, and there is a gap between the two half arrows. The deformable block is made of plastic.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through its opening and closing device, moving frame, and rotating shaft, allows for the following: When a suspension clamp appears on the transmission line, the suspension clamp first pushes the two front L-shaped rotating blocks, causing them to rotate relative to the two front fixed axes. This puts the two front torsion springs in a stored state. After the suspension clamp has completely passed, the two front torsion springs restore the two front L-shaped rotating blocks to their original state. The suspension clamp then passes the two rear L-shaped rotating blocks in the same manner. The user shuts off the first and second motors, pulls the second control rope downwards with one hand, and pulls the first control rope downwards with the other. The second control rope pulls the hinge ring downwards, causing the left end of the rotating plate to rotate downwards and the right end to rotate upwards. This causes the front and rear hinge columns to move upwards along the front and rear slide grooves, respectively. This causes the two blocking blocks to press against the two half-arrows, deforming the lower end of the deformation block and causing it to move out of the limiting cylinder. The tension of the first control rope causes the half-arrow to... With the cylindrical base fully open, both short springs are compressed and stored. The third motor is then activated, its output shaft driving the rotating shaft. This causes the devices at the rear of the moving frame to rotate downwards. Simultaneously, the first control rope is pulled downwards until the rear devices can pass the suspension clamp. The third motor is then turned off, and the first and second control ropes are pulled forward to allow the entire device to pass the suspension clamp. The third motor is then activated again, causing the devices at the rear of the moving frame to rotate upwards until they return to a horizontal position. Once the power line is centered again, the third motor is turned off, and the pulling of the first and second control ropes stops. The spring force of the two short springs causes the semi-cylindrical cover to rotate, and the deformation block is jammed after entering the limiting cylinder, thus passing the suspension clamp. This design eliminates the need for workers to climb to the top of the power tower for disassembly and reassembly to overcome obstacles, avoiding multiple dangerous high-altitude operations and making obstacle crossing more convenient and faster, thus improving the efficiency of removing icing from power transmission lines.

[0039] Two support columns 22 are provided in front of the upper fixed ring frame 14.

Several passive pinions 26 are fixedly connected to the central shaft of the corresponding crushing roller 27. This design is used for crushing ice.

[0040] The semi-cylindrical cover 21 and the semi-cylindrical base 11 are connected by two hinges 213. One end of the two hinges 213 is fixedly connected to the lower end of the right side wall of the semi-cylindrical cover 21, and the other end of the two hinges 213 is fixedly connected to the upper end of the right side wall of the semi-cylindrical base 11.

[0041] Half arrows 3211 are fixedly connected to the left and right sides of the bottom end of the deformable block 321. There is a gap between the two half arrows 3211. The deformable block 321 is made of plastic. This design ensures that the deformable block 321 can be squeezed into the limiting cylinder 311.

[0042] In this embodiment, the power transmission line icing removal device for electrical engineering is used by placing the semi-cylindrical base 11 at the lower end of the power transmission line, so that the power transmission line is located within the lower fixed ring frame 14. The power transmission line is simultaneously squeezed into the left and right U-shaped frames 122. Several friction rollers 126 are in close contact with the power transmission line, and several long springs 125 are in a compressed and stored state, which tightens the semi-cylindrical cover 21 and the semi-cylindrical base 11. The power transmission line is simultaneously located in the gap between the two upper L-shaped rotating blocks 54 and the two corresponding lower L-shaped rotating blocks 54. The first motor 124 and the second motor 24 are turned on. The output shaft of the first motor 124 drives the rear wheel of the pulley 123 and the friction roller 126 on the rear side to rotate. The front wheel of the pulley 123 drives the friction roller 126 on the front side to rotate. The rotating friction roller 126 drives the entire device to move forward relative to the power line through friction. The output shaft of the second motor 24 drives the drive gear 25 to rotate. The drive gear 25 drives several passive small gears 26 to rotate, so that several crushing rollers 27 rotate around the power line to break ice.

[0043] When a suspension clamp appears on the transmission line, the suspension clamp first pushes the two front L-shaped rotating blocks 54, causing the two front L-shaped rotating blocks 54 to rotate with the two front fixed shafts 53 as their base points, so that the two front torsion springs 55 are in a charged state. After the suspension clamp has completely passed, the two front torsion springs 55 cause the two front L-shaped rotating blocks 54 to return to their original state. The suspension clamp passes the two rear L-shaped rotating blocks 54 in the same way. The user turns off the first motor 124 and the second motor 24, pulls the second control rope 37 down with one hand, and pulls the first control rope 212 down with the other hand. The second control rope 37 pulls the hinge ring 35 to move downward. The hinge ring 35 drives the left end of the rotating plate 33 to rotate downward, and the right end of the rotating plate 33 to rotate upward. This drives the two front and rear hinge columns 36 to move upward along the front and rear slide grooves 312, respectively. This drives the two stop blocks 361 to squeeze the two half arrows 3211, causing the lower end of the deformation block 321 to... After deformation, the device moves out of the limiting cylinder 311. The tension of the first control rope 212 causes the semi-cylindrical base 11 to open completely. At this time, both short springs 16 are in a compressed and stored state. Then, the third motor 7 is turned on. The output shaft of the third motor 7 drives the rotating shaft 52 to rotate. The devices on the rear side of the moving frame 5 are all driven to rotate downward. While rotating, the first control rope 212 is pulled downward until the device on the rear side can pass through the suspension clamp. Then, the third motor 7 is turned off. At the same time, the first control rope 212 and the second control rope 37 are pulled forward so that the entire device passes over the suspension clamp. The third motor 7 is turned on again so that the device on the rear side of the moving frame 5 rotates upward until it returns to a horizontal state. After the wire is back in the center of the device, the third motor 7 is turned off and the pulling of the first control rope 212 and the second control rope 37 is stopped. The elasticity of the two short springs 16 causes the semi-cylindrical cover 21 to rotate. The deformable block 321 rushes into the limiting cylinder 311 and is stuck, that is, it passes over the suspension clamp.
