[0002] With the development of society, in order to reduce the losses caused by power outages to users and improve power supply reliability and people's quality of life, live work is now used during the maintenance of existing distribution lines. In the prior art, for live work on 35kv distribution network bypass for replacing the load switch on the pole, bypass cables, bypass load switches, temporary cross arms for bypass cables and other equipment are required, so it is necessary to use work vehicles to assist in cable installation, maintenance and other operations; With the development of society, in order to reduce the losses caused by power outages to users and improve power supply reliability and people's quality of life, live work is now used during the maintenance of existing distribution lines. In the prior art, for live work on 35kv distribution network bypass for replacing the load switch on the pole, bypass cables, bypass load switches, temporary cross arms for bypass cables and other equipment are required, so it is necessary to use work vehicles to assist in cable installation, maintenance and other operations; When the power distribution line is damaged in the field, the staff needs to drive the work vehicle to transport the cable equipment to the location where it needs to be used. At the same time, the field environment is complex. When the work vehicle drives to a bumpy road section, the existing device usually places the cable equipment inside the work vehicle. Because the inside of the cable is made of elastic metal, if the cable wound in the cable equipment placed on the work vehicle cannot be fixed, the cable wound in the cable equipment will become loose with the shaking of the car. After the cable equipment is used, the cables inside it need to be wound to facilitate the transportation of the cable equipment. However, due to the complex outdoor environment, dust will be sticky on the surface of the cable when it is in use. The current technology usually requires the staff to observe the dust on the surface of the cable when winding the cable, and clean the observed dust, and then collect it inside the cable equipment. In this process, since the cable is cylindrical, the staff may not be able to observe it clearly when observing it, which may result in the cable not being completely cleaned.

[0014] 1. In the 35kV mobile cabin bypass operation vehicle and operation method, through the cooperation between the sliding plate, the L-shaped cylinder and the cylinder, when the cylinder is started, the sliding plate is driven to slide to the side away from the cylinder through its output shaft end, and the sliding plate drives the sealing door to slide to the side away from the cylinder through the wedge-shaped groove and the L-shaped cylinder provided on its surface, so that the sealing door does not seal the protection box at this time, and the cable interface between the protection box and the control box is opened, which is convenient for the use of the cable interface. At the same time, when the sealing door is opened and closed, it drives the swing rod connected to the rotation thereof to swing, and the swing rod drives the sliding block to press the fixed body downward through the rectangular block at this time, so that the universal wheel fixedly connected to the bottom of the fixed body is in contact with the ground, so that after the staff removes the protection box from the interior of the car, it is convenient for the protection box to be moved on the ground through the universal wheel, and at the same time, the cable interface is moved through the protection box at this time, which is convenient for the cable interface to be used in different positions.

[0015] 2.

At the same time, the sealing door is closed during this process, thereby avoiding the need for the staff to seal the cable interface after the cable is wound. At the same time, when the sealing door is closed, the sealing door drives the extrusion plate to squeeze the cable wound on the surface of the winding shaft through the fixed rod, thereby avoiding the situation where the cable is not tightly wound around the winding shaft. After the sealing door is completely closed, the extrusion plate is at the top of the winding shaft. At this time, the extrusion plate fixes the cable wound on the surface of the winding shaft, thereby avoiding the looseness of the cable wound on the surface of the winding shaft caused by road bumps.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] With the development of society, in order to reduce the losses caused by power outages in the power supply system to users, improve the reliability of power supply and the quality of life of the people, live operations are used during the maintenance of existing distribution lines. In the prior art, for the live operation of 35kv distribution network bypass for replacing the load switch on the pole under load, it is necessary to use bypass cables, bypass load switches, temporary cross arms for bypass cables and other equipment. On the one hand, a 35kV mobile cabin bypass operation vehicle includes a protective box 15, the interior of the protective box 15 is provided with an opening and closing structure 2, the interior of the protective box 15 is provided with a winding structure 3 for fixing the cable, the interior of the winding structure 3 is provided with a cleaning structure 4, and the interior of the winding structure 3 is provided with an auxiliary structure 5; When the opening and closing structure 2 slides away from the protection box 15, the angle between the cleaning structure 4 and the cable changes. At the same time, the opening and closing structure 2 drives the auxiliary structure 5 to slide on the top of the winding structure 3 to fix the cable wound by the winding structure 3.

[0020] When the power distribution line is damaged in the field environment, the staff needs to drive the work vehicle to transport the cable equipment to the location where it needs to be used. At the same time, the field environment is complex. When the work vehicle travels to a bumpy road section, the existing device usually places the cable equipment inside the work vehicle compartment. Because the inside of the cable is made of elastic metal, if the cable wound in the cable equipment placed on the work vehicle cannot be fixed at this time, the cable wound in the cable equipment will become loose as the compartment shakes. When the present invention is used, the output shaft end of the cylinder 16 drives the opening and closing structure 2 to slide to the side away from the cylinder 16. At this time, the opening and closing structure 2 opens the cable interface inside the protective box 15, which is convenient for the staff to electrically connect the cable to it. At the same time, in the initial state, the auxiliary structure 5 fixes the cable wound by the winding structure 3. When the opening and closing structure 2 moves, the auxiliary structure 5 is driven to move synchronously in the direction away from the cylinder 16. At this time, the auxiliary structure 5 no longer fixes the winding structure, which is convenient for the staff to take and put the cable wound by the winding structure. When the opening and closing structure 2 is closed, the auxiliary structure 5 is driven to smooth the cable wound by the winding structure. After the cable equipment is used, the cables inside it need to be wound to facilitate the transportation of the cable equipment. However, due to the complex outdoor environment, dust will be stuck on the surface of the cable when it is used. The current technology usually involves the staff observing the dust on the cable surface when winding the cable, cleaning the observed dust, and then collecting it inside the cable equipment. In this process, since the cable is cylindrical, the staff may not be able to observe it clearly, which may result in the cable not being completely cleaned. When the cylinder 16 drives the opening and closing structure 2 to slide, the cylinder 16 synchronously drives the cleaning structure 4 to swing, and when the opening and closing structure 2 moves, the cleaning structure 4 is driven to swing in the opposite direction to the above-mentioned cleaning structure 4, so that the angle between the cleaning structure 4 and the surface of the winding structure 3 with the cable wound changes. At this time, when the 3 pairs of cables are wound, the friction between the cleaning structure 4 and the cable cleans the cable surface; A transport vehicle 1 is arranged outside the protection box 15, a carriage 11 is installed at the rear of the transport vehicle 1, a lifting assembly 12 is installed inside the carriage 11, and a side of the carriage 11 away from the protection box 15 is detachably connected to a panel 13; A hollow plate 14 and a cylinder 16 are installed on one side of the protection box 15 close to the lifting assembly 12, and the cylinder 16 is located below the hollow plate 14; A first guide rail 17 is installed on the part of the carriage 11 below the protection box 15 , and a second guide rail 18 is clamped on a side of the first guide rail 17 away from the protection box 15 . Slide grooves are provided inside the first guide rail 17 and the second guide rail 18 .

[0021] Two connecting parts 1501 are symmetrically installed at the bottom of the protective box 15. The two connecting parts 1501 are respectively slidably connected to the sliding grooves opened inside the first guide rail 17 and the second guide rail 18. The connecting part 1501 is T-shaped, and the height of the connecting part 1501 away from the side of the protective box 15 is less than the height of the sliding grooves opened in the first guide rail 17 and the second guide rail 18. There are four universal wheels 1502 symmetrically sliding at the bottom of the protective box 15 for the protective box 15 to slide.

[0022] refer to Figure 1 , Figure 2 and Figure 3 When the present invention is used, the staff removes the enclosure 13 from the bottom of the carriage 11, and then clamps the first guide rail 17 and the second guide rail 18. Finally, the staff pushes the protection box 15, and the protection box 15 slides inside the first guide rail 17 and the second guide rail 18 through the connecting piece 1501, and moves the protection box 15 to the side of the second guide rail 18 away from the protection box 15.

[0023] The opening and closing structure 2 includes a sliding plate 21 fixedly connected to the output shaft end of the cylinder 16. The sliding plate 21 and the output shaft end of the cylinder 16 are slidingly connected to the hollow plate 14. Two wedge-shaped grooves are symmetrically provided on the surface of the sliding plate 21, and L-shaped cylinders 22 are slidingly connected inside the two wedge-shaped grooves respectively. A rectangular groove for the L-shaped cylinder 22 to slide is provided on the side of the protective box 15 close to the cylinder 16, and a sealing door 23 is fixedly connected to the side of the L-shaped cylinder 22 away from the sliding plate 21.

[0024] The present invention takes into account that during the bypass operation, if the cable interface cannot be opened and closed in time, the work efficiency of the staff will be affected. Figure 4 and Figure 4 After moving the protective box 15 to the side of the second guide rail 18 away from the protective box 15, the staff starts the cylinder 16, and the cylinder 16 drives the sliding plate 21 fixedly connected to its output shaft end to slide toward the side away from the cylinder 16. When the sliding plate 21 slides, the wedge-shaped groove opened on its surface drives the two L-shaped cylinders 22 to slide toward the side away from the protective box 15. At this time, the L-shaped cylinder 22 drives the sealing door 23 to slide toward the side away from the cylinder 16, thereby opening the cable interface installed on the surface of the control box 31, making it convenient for the staff to connect the cable at this time.

[0025] The sealing door 23 is fixedly connected to the bottom of both sides close to the cylinder 16 with two rectangular blocks 2301, one side of the two rectangular blocks 2301 is rotatably connected to a rocker arm 24, and the side of the rocker arm 24 away from the sealing door 23 is rotatably connected to a sliding block 25, the sliding block 25 is slidably connected to the protective box 15, a rectangular groove is provided at the bottom of the sliding block 25, a fixed body 26 is provided at the bottom of the sliding block 25, and the fixed body 26 is fixedly connected to the universal wheel 1502.

[0026] The present invention takes into account that during the transportation of the protection box 15 inside the carriage 11, if the height between the universal wheel 1502 and the protection box 15 cannot be adjusted in time, when the protection box 15 is inside the carriage 11, the universal wheel 1502 will contact the carriage 11, and at the same time, since the connecting member 1501 is slidably connected inside the first guide rail 17, the protection box 15 will slide back and forth inside the carriage 11 through the universal wheel 1502 and the connecting member 1501 as the road section bumps, thereby causing damage to the power supply 35; refer to Figure 3 , Figure 6 and Figure 7 When the two sealing doors 23 slide to the side away from the cylinder 16, the sealing door 23 drives the swing rod 24 to swing to the side away from the sealing door 23 through the rectangular block 2301. When the swing rod 24 swings, it drives the sliding block 25 to slide to the side away from the sealing door 23. When the sliding block 25 slides for a distance, the rectangular groove at the bottom of the sliding block 25 will fit with the bottom of the fixed body 26, so that the sliding block 25 continues to move and drives the universal wheel 1502 to contact the ground by squeezing the fixed body 26. At this time, the staff continues to push the protection box 15 to slide to the side away from the second guide rail 18, so that the protection box 15 is separated from the second guide rail 18, and then the protection box 15 moves on the ground through the universal wheel 1502; refer to Figure 3 When the sliding block 25 continues to move and drives the universal wheel 1502 by squeezing the fixed body 26, because the height of the connecting piece 1501 away from the side of the protection box 15 is less than the height of the sliding grooves provided by the first guide rail 17 and the second guide rail 18, the connecting piece 1501 is at the side away from the second guide rail 18. When the second guide rail 18 is disengaged from the connecting piece 1501, the sliding block 25 continues to squeeze the fixed body 26, so that the universal wheel 1502 fixedly connected to the bottom of the fixed body 26 is at a height greater than the height of the connecting piece 1501 at the bottom of the protection box 15, thereby preventing the connecting piece 1501 from contacting the ground.

[0027] When the protection box 15 is used, the connecting piece 1501 and the universal wheel 1502 are inside the first guide rail 17 and the carriage 11. At this time, the fixed body 26 repeats the above-mentioned opposite action, so that the universal wheel 1502 is not in contact with the carriage 11, thereby avoiding damage to the power supply 35 caused by the contact between the universal wheel 1502 and the carriage 11 of the protection box 15.

[0028] The winding structure 3 includes a control box 31 fixedly connected to the protection box 15, the control box 31 is internally rotatably connected to two winding shafts 33, the outer side walls of the two winding shafts 33 are respectively fixedly connected to two limit plates 32, the side of the winding shafts 33 away from the control box 31 is fixedly connected to a rotating disk 34, the control box 31 is internally installed with a power supply 35, the output end of the power supply 35 is electrically connected to a cable interface, and the cable interface is installed on the surface of the control box 31; A cable is wound around the surface of the winding reel 33 , and one end of the cable passes through the control box 31 and the protection box 15 , and the other end of the cable passes through the top of the control box 31 and is snap-connected to the cable interface installed on the surface of the control box 31 .

[0029] The present invention takes into account the storage of cables after use, referring to Figure 8 After moving the protection box 15 to the position where work is required through the universal wheel 1502, the staff rotates the rotating disk 34 to loosen the cable wound on the surface of the winding shaft 33. At the same time, the staff pulls one end of the cable to pull the cable out from the inside of the protection box 15 and the control box 31, thereby facilitating the use of the cable. After the cable is used, the cable is wound through the winding shaft 33.

[0030] The cleaning structure 4 includes a first connecting rod 41 fixedly connected to the sliding plate 21, the first connecting rod 41 is slidably connected to the protective box 15 and the control box 31, the first connecting rod 41 is hingedly connected to a first limiting ring 42 at one end away from the sliding plate 21, the outer wall of the first limiting ring 42 is rotatably connected to a support rod 43, and the support rod 43 is fixedly connected to the control box 31.

[0031] A second connecting rod 44 is fixedly connected to the bottom of the sliding block 25 , and a second limiting ring 45 is hingedly connected to one end of the second connecting rod 44 away from the sliding block 25 . A collecting box 46 fixedly connected to the control box 31 is arranged on the top of the second limiting ring 45 .

[0032] The present invention takes into account that when the cable is taken out from the surface of the winding spool 33 and when the winding spool 33 stores the cable, the dust on the surface of the cable cannot be cleaned in time. Fig. 9 and Fig.10When the sliding plate 21 slides to the side away from the cylinder 16, the sliding plate 21 drives the first limiting ring 42 to swing to the side away from the cylinder 16 through the first connecting rod 41 fixedly connected thereto, and at this time, when the sliding block 25 moves, the second limiting ring 45 is driven to move to the side away from the first connecting rod 41 through the second connecting rod 44, so that at this time, the angle formed by the second connecting rod 44 and the second limiting ring 45 close to the end of the winding shaft 33 will gradually increase, and at the same time, the angle formed by the end away from the winding shaft 33 will gradually decrease. At this time, when the staff extracts the cable wound on the surface of the winding shaft 33, the cable and the second connecting rod 44 are in contact with each other. The rod 44 and the second limiting ring 45 are in contact at an angle away from one end of the winding shaft 33. The dust stuck on the surface of the cable will be cleaned through the angle between the second connecting rod 44 and the second limiting ring 45, and then the dust falls into the inside of the collection box 46 due to its own weight. Similarly, if the sliding block 25 and the sliding plate 21 respectively drive the first connecting rod 41 and the second connecting rod 44 to move toward the side close to the winding shaft 33, the angle between the second connecting rod 44 and the second limiting ring 45 will change synchronously, and the dust on the surface of the cable after use will be collected into the inside of the collection box 46, thereby ensuring the cleanliness of the cable surface.

[0033] The auxiliary structure 5 includes a fixing rod 51 fixedly connected to the bottom of the sealing door 23, and a squeezing plate 52 is fixedly connected to the bottom of the fixing rod 51. The squeezing plate 52 is located at the top of the winding shaft 33, and the distance between the squeezing plate 52 and the winding shaft 33 is slightly larger than the diameter of the cable wound on the surface of the winding shaft 33.

[0034] The present invention takes into account that after the cable is wound on the winding reel 33, if the cable cannot be fixed, the transport vehicle 1 will travel on a bumpy road section, which will cause the cable to loosen. Fig.11 When the staff winds the cable on the surface of the winding spool 33 through the winding structure 3, the sealing door 23 slides to the side close to the cylinder 16 through the cooperation of the cylinder 16, the L-shaped cylinder 22 and the sealing door 23, and the cylinder 16 drives the extrusion plate 52 to move to the side close to the cylinder 16 through the fixing rod 51. If the cable wound on the surface of the winding spool 33 is uneven, the extrusion plate 52 squeezes the uneven cable on the surface of the winding spool 33 when it moves, thereby smoothing the cable. At the same time, when the extrusion plate 52 moves to the side close to the collection box 46 through the cooperation of the sealing door 23 and the fixing rod 51, the extrusion plate 52 fixes the cable wound on the winding spool 33 to prevent the cable from loosening.
