Description

Technical Field

[0001] The present invention relates to the technical field of line maintenance, and specifically to a wire line maintenance device. Background Art

[0002] The high-voltage power transmission method is the most commonly used and economical power transmission method at present. Usually, at the power plant, the power generated by the generator is stepped up in voltage through a transformer, and the stepped-up voltage is transported. The use of high-voltage power transmission can effectively reduce the heat loss generated by the current and the material cost. Because under the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage power transmission can reduce the current during power transmission, thereby reducing the heat loss generated by the current and the material cost of long-distance power transmission.

[0003] After retrieval, a device for high-voltage line maintenance and inspection, with the publication number CN115036841 B, includes at least one set of ice-breaking components. The ice-breaking components include several ice-breaking plates arranged in a circumferential array around the cable, and several ice-breaking plates are spirally wound. The orthographic projection shape of the ice-breaking plate is fan-shaped, and the end of the ice-breaking plate is provided with an ice-breaking part. The cross-sectional projection shape of the ice-breaking part is arc-shaped. A wire passing opening for the high-voltage line cable to pass through is formed between several ice-breaking parts. When the present invention walks, the position of the cable after breaking ice and snow is detected by a flaw detector, so as to identify whether the surface of the cable is damaged under the low-temperature and high-voltage environment, which is convenient for the staff to carry out subsequent maintenance. Combining the two functions of high-voltage line circuit detection and ice-breaking, it achieves multiple functions with one machine, improves the detection efficiency of the staff for high-voltage line cables, and reduces the number of power sources.

[0004] In the above-mentioned retrieved patent, while the cable can be detected, the work of breaking ice and clearing snow on the cable surface is carried out. Although it helps the detection and maintenance of the cable and reduces the damage of ice and snow to the cable, if the surface of the high-voltage cable is covered with thick ice and snow again later, threatening the integrity of the cable, it is necessary to carry out detection and maintenance again, increasing the frequency of cable detection and maintenance, resulting in an increase in maintenance costs. Therefore, a wire line maintenance device is needed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wire line maintenance device, which solves the problem that if the surface of the high-voltage cable is covered with thick ice and snow again later, threatening the integrity of the cable, it is necessary to carry out detection and maintenance again, increasing the frequency of cable detection and maintenance.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

The front end of the rotating rod drives the plurality of ice-breaking rollers to rotate through a transmission component. The rear end of the rotating rod drives the two synchronous rods to rotate through a pulley group.

[0012] Preferably, the infusion pump includes a pump body installed at the rear of the bottom side of the frame body. A pressurizing turbine is rotatably connected inside the pump body. The front end of the pressurizing turbine is fixedly connected with the rear end of the driving shaft.

The output end of the pump body is connected with the input end of the transmission ring through a connecting pipe.

[0013] Preferably, the transmission component includes two worms with opposite thread directions rotatably connected to the bottom side of the front end of the frame body. The rear end of the worm is connected with the rotating rod through three meshing gears four. A worm gear is fixedly connected to the bottom side of the ice-breaking roller. The worm gear is meshed with the outer wall of the worm.

[0014] Preferably, both the front and rear ends of the synchronizing rod at the left end are fixedly connected to the extrusion rollers, and both the front and rear ends of the synchronizing rod at the right end are fixedly connected to the transmission rollers.

[0015] Preferably, the pulley group includes a first pulley fixedly connected to the outer wall of the synchronizing rod and a second pulley fixedly connected to the rear end of the outer wall of the rotating rod, and the first pulley and the second pulley are connected by the inner side of a belt.

[0016] Preferably, the one-way wheel includes an anti-slip wheel rotatably connected to the middle of the rear side of the frame body. The outer wall of the anti-slip wheel is provided with anti-slip lines for increasing friction, and the anti-slip wheel is in rolling contact with the outer wall of the high-voltage cable. A limiting wheel is fixedly connected to the left side of the anti-slip wheel. A plurality of grooves are formed in the outer wall of the limiting wheel, and a limiting head is arranged at the bottom side of the limiting wheel.

[0017] Preferably, the bottom end of the limiting head is connected to the frame body through a torsion spring. The top end of the limiting head abuts against the inside of the groove, and the front side of the limiting head abuts against the frame body.

[0018] Preferably, anti-deviation wheels are rotatably connected to both the rearmost end and the foremost end inside the frame body. The outer walls of the anti-deviation wheels are provided with anti-slip washers. The anti-slip washers are in a convex corrugated shape and are in rolling contact with the outer wall of the high-voltage cable.

[0019] Preferably, a plurality of protrusions are arranged on the outer wall of the ice crushing roller.

[0020] Preferably, a plurality of the spray heads are equidistantly arranged around the inner wall of the transmission ring.

[0021] Working principle: When maintaining the surface of the cable and removing ice and snow on the cable surface, the drive shaft driven by the servo motor rotates. Through two meshing gear sets, the rotating rod is driven to rotate. The rotating rod drives two worms with opposite thread directions to rotate through three meshing gear sets at the front end. The worms drive the worm wheels, causing two ice-breaking rollers connected to the worm wheels to rotate, applying force to the high-voltage cable and the ice and snow layer on the surface of the high-voltage cable, so that the ice and snow crack and break away from the surface of the high-voltage cable. At the same time, the ice-breaking rollers and the frame body together have a tendency to move forward and displace. While displacing, the rotating rod also drives the synchronous rod connected to pulley 1 through pulleys 1 and 2 of different sizes by belt drive for variable-speed transmission, so that the synchronous rods at both ends drive the extrusion rollers and the transmission rollers to rotate respectively. The adjacent two extrusion rollers and the adjacent two transmission rollers rotate in opposite directions, causing the absorbent cotton cloth to continuously displace, be squeezed by the extrusion rollers to dehydrate, and the squeezed side is conveyed to the surface of the high-voltage cable. Following the displacement of the equipment, the water on the surface of the high-voltage cable is sucked dry and cleaned, and the remaining ice and snow are swept away, assisting the subsequent spraying of the anti-ice and snow coating. The drive shaft drives the pressurizing turbine located inside the pump body connected to the rear end, causing the pressurizing turbine to agitate the anti-ice and snow coating conveyed from the storage tank to the pump body through the connecting pipe, pressurize it, and convey it to the cavity inside the transmission ring. The spray head sprays the pressurized anti-ice and snow coating on the surface of the high-voltage cable after the ice and snow cleaning and maintenance following the movement of the equipment. Under normal conditions, the forward movement of the equipment will cause the high-voltage cable to contact the anti-slip wheel, causing the anti-slip wheel to have a tendency to rotate forward, the synchronous limit wheel to have a tendency to rotate forward, and the groove on the limit wheel to apply force to the limit head, causing the limit head to have a backward rotation action and compress the torsion spring. Subsequently, the limit head is driven to reset, enabling the limit wheel and the anti-slip wheel to rotate forward without obstruction. If the equipment has a tendency to move backward, when the high-voltage cable contacts the anti-slip wheel, the anti-slip wheel and the limit wheel will have a tendency to rotate in reverse, and the groove on it will apply force to the limit head. When the stressed limit head has a forward movement tendency, it will be limited and blocked by the part at the rear side of the frame body and cannot rotate, thereby limiting the limit wheel and preventing the limit wheel and the anti-slip wheel from rotating in reverse. The non-rotating anti-slip wheel uses the anti-slip pattern on its surface to increase the friction with the high-voltage cable, thereby blocking the tendency of the equipment to move backward.

[0022] The present invention provides a device for overhauling and maintaining electric wire lines. It has the following beneficial effects:

[0023] 1. The present invention synchronizes the detection of high-voltage cables and the ice-breaking maintenance work. After cleaning the ice and snow on the surface of the high-voltage cables, it can spray anti-ice and snow coatings for reducing ice and snow accumulation. The secondary cleaning of the cable surface with absorbent cotton cloth can reduce the influence of the moisture on the cable surface on the anti-ice and snow coatings, avoid affecting the concentration of the anti-ice and snow coating mixture, ensure its stable effect, and thus perform maintenance to reduce the subsequent accumulation of ice and snow on the surface of the high-voltage cables.

[0024] 2. The present invention dehydrates the absorbent cotton cloth by repeatedly displacing it so that it is squeezed by the extrusion roller, and accelerates the rapid alternation of the side of the absorbent cotton cloth that is pressed tightly against the high-voltage cable, ensuring the water absorption frequency and improving the accuracy of cleaning the moisture on the surface of the high-voltage cable.

[0025] 3. The present invention can block the equipment in a timely manner when it has a backward movement trend, prevent the equipment from retreating, ensure that the equipment can move forward normally, stabilize the working state of the equipment, and improve the working efficiency.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment:

[0041] The embodiment of the present invention provides a wire line inspection and maintenance device, including:

[0042] Please refer to the attached Figure 1 attachment Figure 2 and attachment Figure 10 and attachment

[0043] The frame body 1 is made of aluminum alloy and is erected on the outer wall of the high-voltage cable 2. Cable detection devices 24 for detecting the high-voltage cable 2 are installed at both the left and right ends of the rear side of the frame body 1. The front side of the frame body 1 is in rolling contact with the outer wall of the high-voltage cable 2 through a plurality of ice crushing rollers 8. The outer wall of the ice crushing roller 8 is provided with a plurality of protrusions for increasing friction and increasing the force application points to increase the pressure, so as to perform ice crushing work on the outer wall of the high-voltage cable 2 and the traction device to move forward. A one-way wheel for preventing backward sliding is installed at the middle end of the rear side of the high-voltage cable 2. The servo motor 3 as the driving source is installed at the front side of the bottom of the frame body 1 through a fixing frame. The driving end of the servo motor 3 is fixedly connected to a drive shaft 4. The top end of the drive shaft 4 is connected to a rotating rod 5 through two meshing gear threes;Specifically, since the cross-section of the high-voltage cable 2 is circular, to ensure that the device can move forward normally and reduce the offset and rotation on the high-voltage cable, a part of the weight of the servo motor 3 is taken into account, and it is combined with the aluminum alloy frame 1 with relatively light weight and high strength, so that the center of gravity of the device is concentrated on the servo motor 3 at the bottom side, reducing the deflection generated during the operation of the device and improving the stability of the device operation. The cable detection device 24 synchronously follows the displacement of the equipment to detect the surface of the high-voltage cable 2, and the detection data is sent back to the ground station to detect whether there are any damages or cracks caused by low temperature or ice and snow or accidents on the surface of the high-voltage cable 2.

[0044] Please refer to the appendix Figure 2 - appendix Figure 4 , the rear ends of the two worms 6 with opposite thread directions that are rotatably connected to the bottom side of the front end of the frame 1 are connected to the rotating rod 5 through three mutually meshing gears four. A worm wheel 7 is fixedly connected to the bottom side of the ice-breaking roller 8, and the worm wheel 7 is meshed with the outer wall of the worm 6;

[0045] Specifically, since the thread directions of the two worms 6 are opposite, the rotation directions of the two worm wheels 7 connected to the ice-breaking roller 8 driven by the two worms 6 are opposite, so that when the two ice-breaking rollers 8 rotate, they apply force to the high-voltage cable 2 and the ice and snow layer on the surface of the high-voltage cable 2, so that the ice and snow cracks and detaches from the surface of the high-voltage cable 2, and the ice-breaking roller 8 together with the frame 1 generates a forward trend and moves.

[0046] Please refer to the appendix Figure 2 , appendix Figure 5 and appendix Figure 6 , two mirror-symmetrical arc-shaped frames 9. The two arc-shaped frames 9 are located in the middle of the inside of the frame 1. The outer wall of the arc-shaped frame 9 is sleeved with a water-absorbing cotton cloth 10. The outer periphery of the water-absorbing cotton cloth 10 abuts against the outer wall of the high-voltage cable 2 to absorb the residual moisture on the surface of the high-voltage cable 2. The water-absorbing cotton cloth 10 is squeezed and dehydrated by two transmission rollers 12 at the right end of the arc-shaped frame 9 and displaced by two squeezing rollers 11 at the left end of the arc-shaped frame 9. Adjacent two squeezing rollers 11 are connected by two meshing gears one, and adjacent two transmission rollers 12 are connected by two meshing gears two. Synchronous rods 13 are arranged at the left and right ends of the adjacent sides of the two arc-shaped frames 9. The front and rear ends of the left synchronous rod 13 are fixedly connected to the squeezing rollers 11, and the front and rear ends of the right synchronous rod 13 are fixedly connected to the transmission rollers 12. A pulley one 14 fixedly connected to the outer wall of the synchronous rod 13 is connected to a pulley two 15 fixedly connected to the outer wall of the rear end of the rotating rod 5 through the inner side of the belt;

[0047] Specifically, the convex structure on the surface of the transmission roller 12 can assist its grasping ability for the water-absorbing cotton cloth 10, preventing the phenomenon of slipping during the transmission and movement of the water-absorbing cotton cloth 10. The spacing between adjacent squeezing rollers 11 is smaller than that of the transmission roller 12 to improve the squeezing and dewatering ability of the water-absorbing cotton cloth 10. The rotating rod 5 is also driven by a belt through a pulley 14 of different sizes and a pulley 15 to variably drive the synchronizing rod 13 connected to the pulley 14. The specification of the pulley 14 is smaller than that of the pulley 15, so that the speed of the pulley 14 driven by the belt is greater than that of the pulley 15, and the synchronizing rod 13 connected to the pulley 14, as well as the squeezing roller 11 and the transmission roller 12 connected to the synchronizing rod 13, are synchronously driven at a high speed, improving the rapid alternation of the side of the water-absorbing cotton cloth 10 close to the high-voltage cable 2, ensuring the water absorption frequency. The adjacent two squeezing rollers 11 rotating in opposite directions and the adjacent two transmission rollers 12 rotating in opposite directions cause the water-absorbing cotton cloth 10 to continuously displace, be squeezed by the squeezing roller 11 for dewatering, and the squeezed side is conveyed to the surface of the high-voltage cable 2. Following the displacement of the equipment, the water on the surface of the high-voltage cable 2 is sucked dry and cleaned, and the remaining ice and snow are swept away.

[0048] Please refer to the attached Figure 2 , the attached Figure 7 and the attached Figure 8 , the transmission ring 18, the transmission ring 18 is sleeved on the outer wall of the high-voltage cable 2 and is located at the rear inside the inner wall frame 1. A plurality of spray heads 19 for spraying anti-ice and snow coating are installed on the inner wall of the transmission ring 18, and the plurality of spray heads 19 are equidistantly arranged around the inner wall of the transmission ring 18. A liquid infusion pump for conveying the anti-ice and snow coating is arranged at the bottom side of the transmission ring 18. Liquid storage tanks 20 for storing the anti-ice and snow coating are fixedly connected to the rear sides of the left and right sides of the frame 1. A feed port for adding the anti-ice and snow coating mixture is arranged at the top side of the liquid storage tank 20. The liquid storage tank 20, the liquid infusion pump and the transmission ring 18 are connected by a connecting pipe. Among them, the anti-ice and snow coating is selected as the ZS-611 anti-ice and snow coating;

[0049] Specifically, the liquid storage tank 20 is equipped with an electronic metering valve and a liquid level monitoring device to detect the liquid level height inside the two liquid storage tanks 20. When the liquid level heights in the two liquid storage tanks 20 are not equal, the electronic metering valve in the liquid storage tank 20 with the higher liquid level is closed until the liquid level heights in the two liquid storage tanks 20 are equal, avoiding one liquid storage tank 20 having a weight that is excessively greater than the other liquid storage tank 20 and preventing the equipment from being unbalanced. As the drive shaft 4 drives the pressurizing turbine 17 located inside the pump body 16 connected to the rear end to rotate, the agitation of the pressurizing turbine 17 pressurizes the anti-ice and snow coating in the liquid storage tank 20 and transports it to the inside of the transmission ring 18. The inside of the transmission ring 18 is provided with a cavity communicating with the spray head 19. The spray head 19 sprays the pressurized anti-ice and snow coating onto the surface of the high-voltage cable 2 after the ice and snow cleaning and maintenance as the equipment moves. The previous cleaning of the surface of the high-voltage cable 2 by the absorbent cotton cloth 10 can reduce the influence of the moisture on the surface of the high-voltage cable 2 on the anti-ice and snow coating, avoid affecting the concentration of the anti-ice and snow coating mixture, ensure its stable effect, and thus perform maintenance to reduce the ice and snow accumulated on the surface of the high-voltage cable 2 subsequently.

[0050] Please refer to the appendix Figure 9 - appendix Figure 11 , the one-way wheel includes an anti-slip wheel 21 rotatably connected to the middle of the rear side of the frame body 1. The outer wall of the anti-slip wheel 21 is provided with anti-slip lines to increase the friction force, and the anti-slip wheel 21 is in rolling contact with the outer wall of the high-voltage cable 2. A limiting wheel 22 is fixedly connected to the left side of the anti-slip wheel 21. A plurality of grooves are formed in the outer wall of the limiting wheel 22. A limiting head 23 is provided at the bottom side of the limiting wheel 22. The bottom end of the limiting head 23 is connected to the frame body 1 through a torsion spring. The top end of the limiting head 23 abuts inside the groove, and the front side of the limiting head 23 abuts against the frame body 1

[0051] Specifically, under normal conditions, the forward movement of the equipment will cause the high-voltage cable 2 to contact the anti-slip wheel 21, causing the anti-slip wheel 21 to have a tendency to rotate forward. Synchronously, the limiting wheel 22 has a tendency to rotate forward, and the groove on the limiting wheel 22 exerts a force on the limiting head 23, causing the limiting head 23 to perform a backward rotation action and compress the torsion spring. Subsequently, the limiting head 23 is driven to reset, enabling the limiting wheel 22 and the anti-slip wheel 21 to rotate forward without obstruction. If the equipment has a tendency to move backward, the contact between the high-voltage cable 2 and the anti-slip wheel 21 will cause the anti-slip wheel 21 and the limiting wheel 22 to have a tendency to rotate reversely. When the groove on the limiting wheel 22 exerts a force on the limiting head 23, when the limiting head 23 has a forward movement tendency, it will be limited and blocked by a part of the rear side of the frame body 1 and cannot rotate. Thus, the limiting wheel 22 is limited, preventing the limiting wheel 22 and the anti-slip wheel 21 from rotating reversely. The non-rotating anti-slip wheel 21 uses the anti-slip lines on its surface to increase the friction force with the high-voltage cable 2, thereby blocking the tendency of the equipment to move backward and preventing the equipment from retreating, ensuring the normal forward movement of the equipment.

[0052] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 12 The rearmost and frontmost ends of the inner part of the frame 1 are rotatably connected with an anti-skew wheel 25, and the outer wall of the anti-skew wheel 25 is provided with an anti-slip washer 26. The anti-slip washer 26 is convex and corrugated and rolls in contact with the outer wall of the high-voltage cable 2. The extended parts at the top and bottom ends of the anti-skew wheel 25 are used to prevent it from detaching from the cable when rolling. The inclined surface of the corrugated anti-slip washer 26 is in close contact with the surface of the high-voltage cable. Its rubber material and the raised structure can greatly increase the friction between the cable and the device, thereby reducing the phenomenon of the device tipping over to the left and right and ensuring the stable operation of the device.

[0053] The various components of the device can be disassembled and assembled to carry out the assembly and disassembly of the device to the high-voltage cable. The size of the equipment needs to be changed accordingly according to the diameter of the high-voltage cable 2 to avoid the device being too heavy to work on the high-voltage cable 2.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
