Description

Technical Field

[0001] The present invention relates to the technical field of distribution network planning, in particular to a distribution network planning device based on a distribution network frame. 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 users through distribution facilities. It is a network that plays an important role in distributing electric energy in the power grid. It includes three units: transformation, transmission, and distribution. The task of the power grid is to transmit and distribute electric energy and change the voltage. Currently, power grids are supplied by a large circuit network composed of several poles.

[0003] Current distribution network planning devices mostly use ordinary utility poles as support. When encountering severe weather, such as strong winds and freezing, the broken ends of high-voltage cables may come into contact with the ground. When the high-voltage lines come into contact with the ground, step voltage will be generated. People passing by may be electrocuted, which poses certain safety hazards. When the arc sag of the wires is too large, it may be easy for the wires to swing too much under the action of electrodynamic forces in strong winds or during faults, causing them to get mixed up and cause a short circuit.

[0056] Working principle:

[0057] When in use, place the wire on top of the lower clamp 24, rotate the threaded rod 22 to adjust the position of the upper clamp 23, and fix the wire with the upper clamp 23 and the lower clamp 24. The wire passes through the third groove 617, rests on the top of the connecting column 622, and is connected to the adjacent power pole 1 along the fourth support plate 59 and the second groove 42 in the first support plate 41. The infrared sensor 47 detects the signal from the wire below. When encountering severe weather, such as strong winds and freezing, the high-voltage wire may be broken. When the broken end of the high-voltage wire contacts the ground, a step voltage will be generated. People passing by may be electrocuted, posing a great safety hazard.

[0058] When the wire breaks accidentally, the broken end of the wire droops and contacts the ground. At this time, the drooping wire pulls the first support plate 41 to rotate, driving the first connecting rod 571 and the second connecting rod 572 to rotate. The angle sensor 311 sends a signal, the buzzer 12 sounds an alarm, and the first hydraulic rod 58 stretches to drive the scissor lift 53 to unfold. The unfolded scissor lift 53 drives the wire to move downward, and the wire is bent into a U shape. At the same time, the unfolded scissor lift 53 drives the first connecting rod 571 and the second connecting rod 572 to rotate. The first connecting rod 571 and the second connecting rod 572 pull the first support plate 41 to rotate to the initial state. The third connecting rod 592 and the fourth connecting rod 593 rotate to drive the insulating baffle 36 to rotate parallel to the fourth support plate 59, preventing maintenance personnel from climbing and accidentally touching the broken wire and getting an electric shock.

[0059] When the infrared sensor 47 does not lose the signal, it means that there are still wires under the second support plate 46, and the motor 641 is started. The rotation of the motor 641 drives the first gear 643 to rotate, and the rack 65 also moves upward, driving the winding box 61 to slide upward along the first slide 33. When the winding box 61 moves to the top of the first slide 33, the contact sensor in the first slide 33 sends a signal, and the motor 641 is turned off. The wires also move upward with the winding box 61. When the wires move with the winding box 61, when the infrared sensor 47 loses the signal, it means that the drooping wires have all moved above the utility pole 1. The motor 641 can be turned off at any time according to the signal of the infrared sensor 47. When the maintenance personnel find that the sag of the wires is too large during maintenance, they can also adjust the natural sag curvature of the wires by starting the first hydraulic rod 58 and the motor 641.

[0060] When the winding box 61 moves to the top of the first chute 33 and the signal from the infrared sensor 47 is still present, the second hydraulic rod 613 stretches, driving the third fixed block 614 to move closer to the rack 65. The eighth support plate 62 also moves closer to the rack 65. The second gear 644 is inserted into the engaging groove 626. The fourth auxiliary wheel 642 squeezes the fifth fixed block 631. The fifth fixed block 631 drives the connecting plate 632 to slide closer to the eighth support plate 62. The connecting plate 632 squeezes the wire, and the wire moves along the inclined surface to the top of the winding shaft 621.

[0061] At the same time, the elastically connected wedge block 634 squeezes the fourth fixed block 624, and the fourth fixed block 624 drives the third auxiliary wheel 625 to slide downward along the second slide groove 623. The third auxiliary wheel 625 squeezes the top of the wire, and the second gear 644 is inserted into the bottom of the clamping groove 626 and engages with the clamping groove 626. The motor 641 is started again, and the rotation of the motor 641 drives the first gear 643 and the second gear 644 to rotate, and the winding shaft 621 also rotates accordingly, so that the drooping wires can be stored in the winding box 61. The motor 641 can be turned off after the signal of the infrared sensor 47 disappears.
