Technical Field

[0001] The invention belongs to the field of line maintenance equipment, in particular to a power line cleaning and maintenance equipment. Background Art

[0002] Power lines refer to the lines that connect substations, distribution stations and electricity users to transmit electricity between power plants, substations and electricity users. They are an important part of the power supply system.

[0003] With the progress of society, people's activities are getting larger and larger, and with it comes the need for electric energy. In order to achieve low-consumption transmission of electric energy, high-voltage transmission is usually used when transmitting electric energy to reduce the consumption of electric energy. In order to reduce the cost of power lines in high-voltage transmission, power lines are usually laid in outdoor locations.

[0004] During the use of power transmission lines, since the power transmission lines are exposed to the wild for a long time, it is easy for many foreign objects such as branches, vines, and bird nests to appear on the surface of the power transmission lines. The accumulation of foreign objects on the power transmission lines can easily cause the power transmission lines to be compressed and broken or cause the surface of the power transmission lines to be damaged, resulting in unnecessary property losses.

[0005] To this end, the present invention provides a power line cleaning and maintenance device. Summary of the Invention

[0010] Preferably, a telescopic wheel frame is fixedly connected to the bottom of the mobile body; and a guide wheel is rotatably connected to the end of the telescopic wheel frame, so that the mobile body is less likely to deflect when moving along the power line.

[0011] Preferably, a sponge pad is fixed to the top of the elastic arc steel sheet; the sponge pad is provided on both sides of the corresponding fixing sleeve; this effectively avoids the adhesion of bird droppings and other debris on the surface of the power line, which easily accelerates the oxidation of the surface of the power line.

[0012] Preferably, electric saws are installed on both side walls of the cleaning rod adjacent to the extending ladder; saw blades are installed inside the electric saws; the electric saws are symmetrically arranged on both sides of the cleaning rod; and the situation in which debris such as branches easily damage the power lines is effectively avoided.

The power line cleaning and maintenance equipment described in the present invention has a structural design that extends the ladder to push the cleaning rod toward the power line, and then uses the cleaning teeth to clean debris such as bird nests erected on the power line. This realizes the function of cleaning debris on the power line, and effectively solves the problem that the appearance of debris on the power line easily causes pressure on the power line, resulting in rupture of the power line surface or breakage of the power line.

[0019] 2.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figures 1 to 2 As shown, an embodiment of the present invention describes a power line cleaning and maintenance device, comprising a mobile body 1; a rotating base 2 is installed on the top of the mobile body 1; a plurality of track wheels 3 are installed on the side walls of the mobile body 1; the track wheels 3 are symmetrically arranged on the side walls of the mobile body 1 that are away from each other; a mobile track 4 is installed on the outside of the track wheel 3; an extension ladder 5 is installed on the top of the rotating base 2; a hydraulic rod is installed between the extension ladder 5 and the rotating base 2; the end of the extension ladder 5 is rotatably connected to a cleaning rod 6; a driving motor is installed at the end of the extension ladder 5; the output end of the driving motor is fixedly connected to a driving rod 601; the end of the driving rod 601 is fixedly connected to the side wall of the cleaning rod 6; the top of the cleaning rod 6 is fixedly connected to a plurality of cleaning teeth 7.

[0030] It should be understood that the mobile body 1 serves as the control body of the entire equipment. During operation, when it is necessary to clean up debris on the power line, the crawler wheel 3 can be controlled to rotate through the mobile body 1, so that the crawler wheel 3 drives the mobile crawler 4 to rotate. Through the rotation of the mobile crawler 4, the contact area between the crawler wheel 3 and the ground can be made larger, which effectively avoids the situation where the mobile body 1 sinks into the soil, thereby driving the mobile body 1 to move to the corresponding position, and then the extension ladder 5 can be pushed to tilt upward by the hydraulic rod, and then the length of the extension ladder 5 can be controlled, so that the extension ladder 5 drives the cleaning rod 6 to move, and the cleaning rod 6 is pushed to the position of the power line. After that, the power line can be lifted up by the cleaning rod 6 to clean the power line. The cleaning rod 6 is supported by the cleaning teeth 7, which effectively prevents the power line from being compressed and pulled and broken. At the same time, the cleaning teeth 7 move forward to push down the bird's nest and other debris on the power line. At the same time, a blade can be provided at the bottom position of the cleaning rod 6 to clean up the kites and other debris hanging on the power line (for example, the blade can be driven to move to clean up the debris by moving the mobile body 1, rotating the extended ladder 5 or rotating the cleaning rod 6). This can effectively prevent the debris on the power line from pressuring the power line, causing the power line to rupture or the power line to break. A camera can be provided on the cleaning rod 6, so that the operator can more conveniently observe the cleaning situation when cleaning the power line.

[0031] It should be noted that, in order to accurately control, the contact position of cleaning rod 6 for supporting electric circuit is provided with pressure sensor, when cleaning rod 6 pushes to the position of electric circuit (as the distance between electric circuit and cleaning rod 6 is in 0-5 millimeter and can be determined to belong to contact position), namely when electric circuit contacts cleaning rod 6, pressure sensor has pressure value (as the numerical value of mobile body 1 can display pressure sensor), and when electric circuit does not contact cleaning rod 6, pressure sensor does not have pressure value, therefore can accurately control cleaning rod 6 according to whether numerical value is supported on electric circuit according to pressure sensor, make cleaning rod 6 not transition and support electric circuit, also can not occur the phenomenon that the position that cleaning rod 6 stops and electric circuit are farther away. Or take the picture of electric circuit by the camera on cleaning rod 6 to judge whether electric circuit contacts with cleaning rod 6 (as operating personnel judge whether cleaning rod 6 contacts with electric circuit by the picture taken).

[0032] like Figures 2 to 5When cleaning, the cleaning rod 6 is lifted up and the cleaning teeth 7 are lifted up, and the cleaning teeth 7 are lifted up and the cleaning rod 6 is lifted up, so that the cleaning teeth 7 can be lifted up and the cleaning rod 6 is lifted up. When cleaning, the cleaning teeth 7 are lifted up and the cleaning rod 6 is lifted up, and the cleaning rod 6 is lifted up and the cleaning rod 6 is lifted up, so that the cleaning teeth 7 are lifted up and the cleaning rod 6 is lifted up, so that the cleaning teeth 7 are lifted up and the cleaning rod 6 is lifted up, so that the cleaning

[0033] like Figures 4 and 5As shown, the interior of the cleaning rod 6 is slidably connected to a longitudinal sliding block 10; a spring is fixedly connected between the bottom of the longitudinal sliding block 10 and the side wall of the cleaning rod 6; the longitudinal sliding block 10 is arranged at the position corresponding to the elastic arc steel sheet 8; the top of the longitudinal sliding block 10 is fixedly connected to a fixed sleeve 9; the fixed sleeve 9 is sleeved at the middle position of the elastic arc steel sheet 8; the interior of the cleaning rod 6 is slidably connected to a transverse sliding block 11; the side wall of the transverse sliding block 11 is fixedly connected to a guide block 111; the cleaning rod 6 is slidably connected to a longitudinal sliding block 11; the side wall of the transverse sliding block 11 is fixedly connected to a guide block 111; the cleaning rod 6 is slidably connected to a longitudinal sliding block 10 ... A guide groove is provided inside the cleaning rod 6; the guide block 111 is arranged corresponding to the guide groove; a spring is fixedly connected between the transverse sliding block 11 and the side wall of the cleaning rod 6; the transverse sliding block 11 is arranged at a position corresponding to the elastic arc steel sheet 8; a pulling sleeve 12 is fixedly connected to the top of the transverse sliding block 11; the pulling sleeve 12 is sleeved on the surface of the elastic arc steel sheet 8; a pull rope 13 is fixedly connected between the bottom of the longitudinal sliding block 10 and the side wall of the transverse sliding block 11 away from the longitudinal sliding block 10; When the lifting rod 6 is pulled back, the lifting rod 6 is lowered, and the lifting rod 6 is lifted and lowered, so that the lifting rod 6 can be lifted and lowered.

[0034] It should be understood that when the power line is not squeezing the elastic curved steel sheet 8, the elastic curved steel sheet 8 returns upward, that is, the bottom spring of the longitudinal sliding block 10 squeezes the elastic curved steel sheet 8 and returns it upward, at which time the pull rope 13 is stretched, thereby pulling the pull sleeve 12 to move. In addition, when the power line squeezes the elastic curved steel sheet 8, the elastic curved steel sheet 8 descends, at which time the pull rope 13 becomes loose, and the spring between the transverse sliding block 11 and the side wall of the cleaning rod 6 pushes the pull sleeve 12 toward the fixed sleeve 9. In other words, the pull sleeve 12 can be driven to move left and right by squeezing the elastic curved steel sheet 8 and not squeezing the elastic curved steel sheet 8.

[0035] like Figure 1As shown, a telescopic wheel frame 15 is fixedly connected to the bottom of the mobile body 1; the end of the telescopic wheel frame 15 is rotatably connected to the guide wheel 14; during operation, when the mobile body 1 moves to the bottom of the power line and needs to move along the power line, the telescopic wheel frame 15 can be controlled to extend, thereby making the guide wheel 14 contact with the ground, and the direction of the guide wheel 14 is always facing forward, so that the mobile body 1 can better maintain straight travel during the movement, so that the mobile body 1 is less likely to deviate when moving along the power line.

[0036] like Figures 4 and 5 As shown, a sponge pad 16 is fixed to the top of the elastic arc steel sheet 8; the sponge pad 16 is provided on both sides of the corresponding fixing sleeve 9; during operation, while the elastic arc steel sheet 8 is wrapping the power line, the sponge pad 16 can wrap the power line, and before the ladder 5 is extended, the sponge pad 16 can be moistened, so that the power line can be wiped by the sponge pad 16, effectively avoiding the adhesion of bird droppings and other debris on the surface of the power line, which can easily accelerate the oxidation of the surface of the power line.

[0037] like Figure 2 and Figure 6 As shown, electric saws 17 are installed on the two side walls adjacent to the cleaning rod 6 and the extending ladder 5 (the electric saw 17 here can be a remote-controlled electric saw of model TDDJ-100, and the electric saw 17 in the application document can be controlled like the remote-controlled electric saw TDDJ-100, and the electric saw has its own drive and uses an external power supply. The power supply can be connected to the mobile body 1 and uses the overall power supply of the entire device to power itself); a saw blade 18 is installed inside the electric saw 17; the electric saw 17 is symmetrically arranged on both sides of the cleaning rod 6; during operation, when the cleaning rod 6 is moving forward, if branches, twigs and other debris are too close to the power line or in contact with the power line, the saw blade 18 can be driven by the electric saw 17 to rotate, and then the debris can be sawed off, effectively avoiding the situation where branches and other debris easily cause damage to the power line.

[0038] like Figure 3 and Figure 6 As shown, positioning grooves 191 are provided on the two side walls adjacent to the cleaning rod 6 and the extending ladder 5; a positioning block 19 is fixed to the side wall of the electric saw 17; the positioning block 19 is rotatably connected to the inside of the positioning groove 191; a connecting rod 20 is fixed to the bottom of the electric saw 17; a counterweight ball 21 is fixed to the end of the connecting rod 20 away from the electric saw 17; during operation, as the cleaning rod 6 moves forward, the connecting rod 20 and the counterweight ball 21 will drive the electric saw 17 to rotate, so that the saw blade 18 installed on the electric saw 17 will always face forward, thereby ensuring the cutting effect of the saw blade 18, and at the same time, the positioning groove 191 restricts the positioning block 19, so that the electric saw 17 can better maintain stability during the rotation process.

[0039] like Figures 2 to 3 As shown, the cleaning rod 6 is also fixedly connected with a driving rod 601 at the position corresponding to the driving motor, and the two driving rods 601 are symmetrically arranged; the end of the driving rod 601 that is not fixedly connected to the driving motor is fixedly connected with an anti-falling block 22; the anti-falling block 22 is rotationally connected to the inside of the extension ladder 5; during work, when the driving motor drives the driving rod 601 to adjust the angle of the cleaning rod 6, the other driving rod 601 can rotate together with the cleaning rod 6, and then by extending the ladder 5 to the restriction of the anti-falling block 22, the rotation of the cleaning rod 6 can be made more stable. It should be understood that the extension ladder 5 is provided with a driving motor, and the driving motor is connected to a driving rod 601, so that the driving motor drives the driving rod 601 to rotate, thereby realizing adjusting the angle of the cleaning rod 6.

[0040] like Figure 2 As shown, a plurality of ball bearings 23 are provided between the anti-slip block 22 and the extending ladder 5; the side walls of the ball bearings 23 are in contact with the side walls of the anti-slip block 22 and the extending ladder 5; during operation, when the anti-slip block 22 rotates inside the extending ladder 5, the ball bearings 23 can convert the sliding friction between the anti-slip block 22 and the extending ladder 5 into rolling friction, thereby reducing the wear between the anti-slip block 22 and the extending ladder 5 and increasing the service life of the device.

[0041] like Figure 4 As shown, the interior of the longitudinal sliding block 10 is rotatably connected to the anti-wear wheel 24; a wheel groove is provided inside the cleaning rod 6; the wheel groove is provided at a position corresponding to the anti-wear wheel 24; during operation, when the longitudinal sliding block 10 slides inside the cleaning rod 6, the anti-wear wheel 24 rolls inside the wheel groove, which can reduce the friction between the longitudinal sliding block 10 and the cleaning rod 6, thereby reducing the wear between the longitudinal sliding block 10 and the cleaning rod 6.

[0042] During operation, when it is necessary to clean the debris on the power line, the crawler wheel 3 can be used to drive the mobile crawler 4 to rotate. The rotation of the mobile crawler 4 can make the contact area between the crawler wheel 3 and the ground larger, effectively avoiding the situation where the mobile body 1 sinks into the soil, and then drives the mobile body 1 to move to the corresponding position, and then the hydraulic rod can be used to push the extension ladder 5 to tilt upward, and then the length of the extension ladder 5 can be controlled, so that the extension ladder 5 drives the cleaning rod 6 to move, and the cleaning rod 6 is pushed to the position of the power line. After that, the power line can be lifted up by the cleaning rod 6. The power lines are supported, which effectively prevents the power lines from being broken due to compression and pulling. At the same time, the cleaning teeth 7 move forward to push down bird nests and other debris installed on the power lines. At the same time, a blade can be provided at the bottom of the cleaning rod 6 to clean up debris such as kites hanging on the power lines, thereby effectively preventing the debris on the power lines from pressuring the power lines, resulting in rupture of the power line surface or breakage of the power lines. A camera can be provided on the cleaning rod 6, so that the operator can more conveniently observe the cleaning situation when cleaning the power lines.

[0043] When the cleaning teeth 7 are cleaning the debris on the power line, when the ladder 5 is extended to push the cleaning rod 6 toward the power line, the cleaning rod 6 can push the elastic arc steel sheet 8 to the bottom of the power line, and then push the cleaning rod 6 to press the elastic arc steel sheet 8 onto the power line. The elastic arc steel sheet 8 is squeezed with the power line and deformed, and then wrapped around the surface of the power line, so that the elastic arc steel sheet 8 can be used to push down the debris that is close to the power line, so that the cleaning effect of the power line is better.

[0044] When the power line is cleaned and the cleaning rod 6 needs to be retracted, the cleaning rod 6 can be driven down by extending the ladder 5, so that the elastic arc steel sheet 8 wrapped on the surface of the power line pulls the longitudinal sliding block 10 through the fixed sleeve 9 (equivalent to the power line not squeezing the elastic arc steel sheet 8 so that the elastic arc steel sheet 8 is reset upward, that is, the bottom spring of the longitudinal sliding block 10 squeezes the elastic arc steel sheet 8 to reset upward), so that the longitudinal sliding block 10 pulls the transverse sliding block 11 through the pull rope 13, so that the transverse sliding block 11 slides in the direction away from the side of the longitudinal sliding block 10 (it should be understood that when the power line squeezes the elastic arc steel sheet 8, the elastic arc steel sheet 8 descends, at this time the pull rope 13 becomes loose, and the spring between the transverse sliding block 11 and the side wall of the cleaning rod 6 pushes the pulling sleeve 12 to move toward the fixed sleeve 9). During the sliding of the transverse sliding block 11, the elastic arc steel sheet 8 can be stretched by pulling the sleeve 12, and the elastic arc steel sheet 8 can be stretched out, thereby effectively avoiding the elastic arc steel sheet 8 from being wrapped too tightly on the power line, and the power line may be pulled and broken during the pulling process. At the same time, during the sliding of the transverse sliding block 11, the guide block 111 can guide the transverse sliding block 11, so that the sliding of the transverse sliding block 11 is more stable.

[0045] When the mobile body 1 moves to the bottom of the power line and needs to move along the power line, the retractable wheel frame 15 can be controlled to extend, so that the guide wheel 14 contacts the ground and the direction of the guide wheel 14 is always facing forward, so that the mobile body 1 can better maintain a straight line during the movement, and the mobile body 1 will be less likely to deviate when moving along the power line.

[0046] During the process of wrapping the power line with the elastic arc steel sheet 8, the sponge pad 16 can wrap the power line. Before the ladder 5 is extended, the sponge pad 16 can be moistened so that the power line can be wiped by the sponge pad 16, effectively avoiding the adhesion of bird droppings and other debris on the surface of the power line, which can easily accelerate the oxidation of the surface of the power line.

[0047] When the cleaning rod 6 is moving forward, if branches, twigs and other debris are too close to the power line or in contact with the power line, the electric saw 17 can drive the saw blade 18 to rotate, and then the debris can be sawed off, effectively avoiding the situation where branches and other debris can easily cause damage to the power line.

[0048] During the forward movement of the cleaning rod 6, the connecting rod 20 and the counterweight ball 21 will drive the electric saw 17 to rotate, so that the saw blade 18 installed on the electric saw 17 will always face forward, thereby ensuring the cutting effect of the saw blade 18. At the same time, the positioning block 19 is restricted by the positioning groove 191, so that the electric saw 17 can be better maintained in the process of rotation.

[0049] When the driving motor drives the driving rod 601 to adjust the angle of the cleaning rod 6, the other driving rod 601 will rotate together with the cleaning rod 6, and then the rotation of the cleaning rod 6 can be made more stable by extending the ladder 5 to limit the anti-slip block 22.

[0050] When the anti-slip block 22 rotates inside the extending ladder 5, the ball 23 can convert the sliding friction between the anti-slip block 22 and the extending ladder 5 into rolling friction, thereby reducing the wear between the anti-slip block 22 and the extending ladder 5 and increasing the service life of the device.

[0051] When the longitudinal sliding block 10 slides inside the cleaning rod 6, the anti-wear wheel 24 rolls inside the wheel groove, which can reduce the friction between the longitudinal sliding block 10 and the cleaning rod 6, thereby reducing the wear between the longitudinal sliding block 10 and the cleaning rod 6.
