Description

Technical Field

[0001] The present invention relates to the technical field of power grid equipment, and more specifically, to a cable line device for planning a power distribution network. Background Art

[0002] A distribution network refers to an electric power grid that receives electric energy from a transmission network or a regional power plant and distributes it locally or step by step according to voltage to various types of users through distribution facilities. A distribution network is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. The topological analysis of a distribution network is based on the connection relationship of distribution electrical components. The entire distribution network is considered as a topological diagram combining lines and points. Then, the topological connection analysis of the entire network is performed based on power nodes, switch nodes, etc. It is the basis for other analyses of the distribution network, such as state estimation, flow calculation, fault location, isolation and power supply restoration, and network reconstruction.

[0003] In the basic power grid construction of distribution network projects, cable support devices, as a planning facility for the foundation of distribution networks, play a relatively important role.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of 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.

[0030] First embodiment

[0031] As attached Figure 1-4 In one embodiment of the present invention, a winding wheel 46 is provided to wind up the winding rope 48, so that the winding rope 48 pulls the counterweight 24 to rise and fall, thereby controlling the tightness of the cable body 5 on the support assembly 1. According to different seasons, when the cable body 5 is in a relatively relaxed state, the winding wheel 46 is unwound to make the counterweight 24 drop under the influence of gravity, and the cable body 5 bends inside the tension adjustment device 2, thereby making the cable body 5 in a taut state, and the tension of the cable body 5 is detected by the pressure sensor 410 to avoid excessive tension of the cable body 5, which may cause the cable body 5 to break.

[0032] A cable line device for planning a distribution network rack includes a support component 1, multiple tension adjustment devices 2 are arranged on both sides of the support component 1, and guide components 3 are arranged on one side of the tension adjustment device 2 at both ends of the support component 1, and a cable body 5 is sleeved inside the guide component 3.

[0033] As attached Figure 2 As shown, the support assembly 1 includes a mounting and fixing ring 11 fixedly mounted on the tower pole, and threaded connection blocks 12 are provided on the upper and lower sides of the mounting and fixing ring 11. The threaded connection blocks 12 fix the mounting and fixing ring 11 on the outer surface of the tower pole through bolts, and both sides of the upper end of the mounting and fixing ring 11 are fixedly connected to support rods 13, and the lower end of the mounting and fixing ring 11 is located at one end of the support rod 13 and is fixedly connected to a reinforcement rod 14, and a plurality of transverse rods 15 are fixedly connected inside the support rod 13, and a protective cover 16 is fixedly connected to the top of the transverse rod 15, and adjustment components 4 are fixedly connected to the inside of the protective cover 16 on both sides of the top of the transverse rod 15, and the bottom of the adjustment component 4 is connected to the tension adjustment device 2.

[0034] As attached Figure 3 As shown, the adjustment component 4 includes a tightening motor 41 fixedly mounted on the top of the transverse rod 15, a driving gear 42 is provided on one side of the tightening motor 41, the top of the transverse rod 15 is located on one side of the tightening motor 41 and is fixedly connected to a fixing frame 45, a rotating rod 44 is rotatably mounted inside the fixing frame 45, both ends of the rotating rod 44 are fixedly sleeved with a winding wheel 46, the winding wheels 46 are rotatably mounted on both sides of the inside of the fixing frame 45, one end of the rotating rod 44 is fixedly connected with a transmission gear 43, the outer surface of the transmission gear 43 is meshed with the outer surface of the driving gear 42, the outer surface of the winding wheel 46 is wrapped with a winding rope 48, and the winding rope 48 is fixedly sleeved with a fixed bead 47 on the side close to the winding wheel 46.

[0035] By fixing the bead 47 on the position of the winding rope 48 , the tension adjustment device 2 can clamp the cable body 5 in a corresponding time period to prevent the cable body 5 from slipping inside the limiter 21 due to the gravity pulling of the counterweight block 24 .

[0036] Among them, both ends of the transverse rod 15 are provided with limiting holes 411, and the top of the transverse rod 15 is located on one side of the limiting hole 411 and is fixedly connected with a guide block 49, and a pressure sensor 410 is arranged inside the guide block 49. The top of the pressure sensor 410 is arc-shaped, and the winding rope 48 is slidably installed on the outer surface of the pressure sensor 410. The pressure of the winding rope 48 on the pressure sensor 410 is detected by the pressure sensor 410, and then the state of the cable body 5 is judged. When the cable body 5 is in tension, a supporting force is generated on the pressing wheel 23, so that the pressure detected by the pressure sensor 410 becomes smaller. At this time, the tightening motor 41 controls the winding wheel 46 to wind up. When the cable body 5 is in a relatively relaxed state, at this time, the counterweight block 24 is affected by gravity, and the pressing wheel 23 descends and presses to the top of the cable body 5, so that the tightness of the cable body 5 is automatically adjusted, and the pressing wheel 23 presses the cable body 5 to adjust the tightness of the cable body 5.

[0037] Second embodiment

[0038] As attached Figure 1-6 In one embodiment of the present invention, when the cable body 5 is broken, in order to prevent the broken surface of the cable body 5 from contacting the ground, the cable body 5 is in a loose state and cannot support the pressing wheel 23, so that the counterweight 24 is affected by gravity and descends, and pulls the cable body 5 to bend, so as to prevent the cable body 5 from automatically shrinking and the broken surface from contacting the ground, thereby posing a safety hazard. The fixed bead 47 is provided to prevent the broken end of the cable body 5 from detaching from the tension adjustment device 2 and slipping.

[0039] The second embodiment is further optimized relative to the first embodiment in that: the tension adjustment device 2 includes a limit member 21 fixedly mounted on the bottom of the transverse rod 15, a clamping assembly 25 is movably mounted on one side of the limit member 21, a support frame 22 is provided on the side of the limit member 21 away from the clamping assembly 25, the two sides of the top of the support frame 22 are fixedly connected to one end of the winding rope 48, a pressing wheel 23 is rotatably mounted on the upper end of the support frame 22, a counterweight 24 is fixedly connected to the bottom of the support frame 22, the support frame 22 is movably sleeved on the outer surface of the cable body 5, and the cable body 5 is respectively located between the pressing wheel 23 and the counterweight 24, and the cable body 5 is always under downward pressure through the provided counterweight 24. When the cable body 5 is in a relatively loose state, the counterweight 24 is affected by gravity and descends, thereby automatically adjusting the tightness of the cable body 5.

[0040] Among them, the limiting member 21 includes a connecting frame 211, a rotating shaft 214 is rotatably installed at the upper end inside the connecting frame 211, and rotating blocks 215 are rotatably installed on the outer surfaces of both ends of the rotating shaft 214. A movable rod 212 is rotatably installed at the bottom of the connecting frame 211, and a sleeve 213 is rotatably installed at the lower end of the connecting frame 211 inside the movable rod 212. The sleeve 213 rotates at the bottom of the connecting frame 211 to avoid friction between the cable body 5 and the tension adjustment device 2, thereby causing wear on the surface of the cable body 5.

[0041] Among them, the outer surface of one side of the rotating block 215 is fixedly connected with an arc-shaped tooth 216, and the side of the rotating block 215 away from the arc-shaped tooth 216 is fixedly connected to a limiting rod 217, and a limiting groove 218 is arranged inside the limiting rod 217, and the limiting groove 218 is movably sleeved on the outer surface of the winding rope 48. Since the limiting groove 218 is arranged inside the limiting rod 217, the winding rope 48 will move inside the limiting groove 218. When the fracture surface of the cable body 5 is about to pass through the pushing wheel 255, the fixed sleeve bead 47 will pass through the top of the limiting rod 217, pressing the limiting rod 217, and then causing the rotating block 215 to rotate. Through the meshing of the arc-shaped tooth 216 and the lifting rack 252, the pushing wheel 255 rises, and the pushing wheel 255 squeezes the cable body 5 to the bottom of the cable slot 257.

[0042] Among them, the clamping assembly 25 includes a movable frame 251, the shape of the movable frame 251 is H-shaped, the upper end of the movable frame 251 is movably sleeved inside the transverse rod 15, both ends of one side of the lower end of the movable frame 251 are fixedly connected with an extrusion frame 254, one side of the upper end of the extrusion frame 254 is rotatably installed with a driving wheel 255, both ends of the upper end of the movable frame 251 close to the limit member 21 are fixedly connected with a lifting rack 252, the outer surface of the lifting rack 252 is meshed with the outer surface of the arc-shaped tooth 216 on one side of the rotating block 215, and the inner wall of the upper end of the movable frame 251 is provided with a positioning groove 253.

[0043] Among them, sleeve grooves 151 are opened on both sides of the interior of the transverse rod 15, one side of the sleeve groove 151 is fixedly connected to the limiting rib 152, the upper end of the movable frame 251 is movably sleeved in the interior of the sleeve groove 151, and the positioning groove 253 is movably sleeved on the outer surface of the limiting rib 152.

[0044] The bottom of the transverse rod 15 is located on one side of the movable frame 251 and is fixedly connected with a positioning block 256 . The bottom of the positioning block 256 is V-shaped, and both sides of the cable slot 257 are rough surfaces.

[0045] Through the V-shape at the bottom of the positioning block 256 and the rough surfaces on both sides of the cable slot 257, when the pushing wheel 255 rises and squeezes the cable body 5 to the bottom of the cable slot 257, the cable body 5 will be clamped to prevent the cable body 5 from slipping inside the pressing wheel 23. At the same time, the fixed bead 47 will be clamped on the top of the limit rod 217 to prevent the counterweight block 24 from causing the pressing wheel 23 to press the cable body 5 again, so that the cable body 5 stops falling.

[0046] Third embodiment

[0047] As attached Figure 1 and 7 This is an embodiment of the present invention. According to the planned laying direction of the cable body 5, when turning is required, the fastening bolts 37 are rotated according to the direction of turning to loosen the rotating ring 35 and the guide frame 31. The rotating ring 35 is rotated to make the rotating rollers 36 at the two ends of the rotating ring 35 rotate in opposite directions, thereby supporting and guiding the rotation direction of the cable body 5. By rotating the guide rod 32, the guide frame 31 can be freely turned at the bottom of the transverse rod 15, so that the device can adapt to planning and laying in different directions.

[0048] The third embodiment is further optimized relative to the second embodiment in that the guide assembly 3 includes a guide frame 31, a rotating guide rod 32 is fixedly connected to the top of the guide frame 31, the rotating guide rod 32 is rotatably installed inside one end of the transverse rod 15, a limiting ring groove 33 is provided inside the guide frame 31, a rotating ring 35 is rotatably installed inside the limiting ring groove 33, rotating rollers 36 are rotatably installed on both sides of the rotating ring 35, and the rotating rollers 36 are rotatably installed on the outer surface of the cable body 5.

[0049] The cable body 5 is supported on both sides by rotating the roller 36. When the cable body 5 slides inside the rotating roller 36, the rolling friction replaces the sliding friction through the rolling of the rotating roller 36, so as to avoid the surface wear of the cable body 5 when it moves inside the guide assembly 3. At the same time, when the cable body 5 turns on the outer surface of the rotating roller 36, the cable body 5 is supported, and the guidance is achieved by the rotation of the rotating guide rod 32 inside the transverse rod 15.

[0050] Among them, an opening is provided on one side of the guide frame 31, and fastening grooves 34 are provided on both sides of the opening inside the guide frame 31, and threaded holes are provided on four sides of the rotating ring 35. The internal threads of the threaded holes are connected with fastening bolts 37, and the fastening bolts 37 are clamped and installed in the fastening grooves 34. The rotating ring 35 is fixed to the inside of the guide frame 31 by the fastening bolts 37. The fastening bolts 37 are locked in the fastening grooves 34 to achieve the fixing of the rotating ring 35 in the guide frame 31. When the cable body 5 is laid horizontally, the rotating rollers 36 are located on the upper and lower sides of the cable body 5 to prevent the cable body 5 from being squeezed and worn by the gravity acting on the guide assembly 3. When the cable body 5 needs to turn, the rotating rollers 36 can be rotated to the left and right sides of the cable body 5 to support the turning of the cable body 5 and support and guide the bending part of the cable body 5.

[0051] Working principle of the present invention: When in use, the cable body 5 passes through the inside of the support frame 22 between the pressing wheel 23 and the counterweight block 24, passes through the inside of the sleeve 213 and the surface of the pushing wheel 255, and passes between the rotating rollers 36. According to the laying length of the cable body 5, the position of the fixed bead 47 at one end of the winding rope 48 is adjusted to control the descending height of the counterweight block 24.

[0052] During laying, the cable body 5 is in a relatively loose state. At this time, the counterweight 24 is affected by gravity, the pressing wheel 23 descends, and presses to the top of the cable body 5, and the tightness of the cable body 5 is automatically adjusted. The pressing wheel 23 presses the cable body 5, and the cable body 5 is in a relatively tight state. When the cable body 5 is tight, it will generate a supporting force on the pressing wheel 23, so that the pressure detected by the pressure sensor 410 becomes smaller. At this time, the tightening motor 41 controls the winding wheel 46 to wind up, and then automatically adjusts the support frame 22 to the corresponding height, thereby realizing automatic adjustment of the tightness of the cable body 5, so that the cable body 5 is in an ideal state, avoiding external influences and affecting the service life of the cable body 5.

[0053] When the cable body 5 is broken, in order to prevent the broken surface of the cable body 5 from contacting the ground, at this time, the cable body 5 is in a loose state and cannot support the pressing wheel 23, so that the counterweight block 24 is affected by gravity and descends, and pulls the cable body 5 to bend, thereby preventing the cable body 5 from automatically shrinking. When the broken surface of the cable body 5 is about to pass through the pushing wheel 255, the fixed sleeve bead 47 will pass through the inside of the limiting hole 411 and stay on the top of the limiting rod 217, so that the limiting rod 217 is pressed, thereby causing the rotating block 215 to rotate, and the pushing wheel 255 is raised through the engagement of the arc teeth 216 with the lifting rack 252, and the pushing wheel 255 squeezes the cable body 5 to the bottom of the cable slot 257, and the broken end of the cable body 5 is clamped inside the cable slot 257, thereby preventing the cable body 5 from being separated from the inside of the pushing wheel 255 and the sleeve 213, thereby preventing the broken end of the cable body 5 from falling to the ground.

[0054] The rotating ring 35 is fixed inside the guide frame 31 by locking the fastening bolts 37 inside the fastening slots 34. When the cable body 5 is laid horizontally, the rotating rollers 36 are adjusted to be located at the upper and lower sides of the cable body 5 to prevent the cable body 5 from being squeezed and worn by the guide assembly 3 due to the force of gravity. When the cable body 5 needs to turn, the rotating rollers 36 can be rotated to the left and right sides of the cable body 5 to support the turning of the cable body 5 and support and guide the bending part of the cable body 5.
