Description

Foldable bird-proof isolation net for substation equipment portal frame Technical Field The invention relates to a foldable bird-preventing isolation net for a portal of substation equipment. Background The transformer substation is used as a core hub of the power system, and the safe and stable operation of equipment of the transformer substation is directly related to the reliability of power supply of a power grid. The equipment portal in the transformer substation is used as a supporting and protecting structure of various power equipment, the clearance is easy to become a place for nesting and inhabiting birds, and feces, nesting sundries and the like generated by the activities of birds are easy to fall onto the surface of the power equipment below, so that faults such as equipment insulation reduction and short circuit tripping are caused, and large-area power failure is caused when the faults are serious, so that great losses are caused to the safety of a power system and the social production and life. Therefore, the bird-preventing isolation device is arranged at the portal of the substation equipment to prevent birds from entering the gap of the portal of the equipment, so that the bird-preventing isolation device becomes a necessary measure for guaranteeing the safe operation of the substation equipment. At present, most of anti-bird isolation nets used for equipment door frames of transformer substations are of an integrated fixing structure, the size and the shape of the anti-bird isolation nets are fixed, and the anti-bird isolation nets cannot be flexibly adjusted according to the actual gap size and the installation space of the equipment door frames. Because the equipment portal specifications in different areas in the transformer substation are different, the gap shapes are of irregular structures, the integral fixed isolation net is difficult to be tightly attached to the portal gap during installation, the problems of loose installation, untight attachment and the like are easy to occur, loopholes exist in anti-bird protection, and the anti-bird effect cannot be fully exerted. Meanwhile, the integrated isolation net has large volume, occupies more space in the transportation and storage processes, is inconvenient to carry, increases labor intensity of constructors, needs to carry out integral carrying and operation on the isolation net during installation, disassembly and maintenance, has poor suitability, cannot be quickly matched with equipment portal frames with different specifications, and has low installation efficiency. In addition, the existing part foldable bird-preventing isolation net is unreasonable in folding structure design, cannot be stably fixed after being folded, is difficult to form a structure capable of tightly filling gaps of a portal frame of equipment, lacks a reliable fixing mechanism and a locking mechanism, is easy to loosen and unfold after being folded, affects a protection effect, is mainly rigidly connected, cannot be flexibly adjusted according to the appearance of the portal frame, is poor in stability after being installed, is easy to fall off due to the influence of external environment (such as wind power, equipment vibration and the like) in the long-term use process, and further reduces the reliability of bird-preventing isolation. Disclosure of Invention The invention aims at improving the problems existing in the prior art, namely the technical problem to be solved by the invention is to provide a foldable anti-bird isolation net for a substation equipment portal. In order to achieve the aim, the technical scheme is that the substation equipment portal frame foldable bird-preventing isolation net comprises a first isolation net, a second isolation net, folding assemblies, fixing mechanisms and locking mechanisms, wherein the second isolation net is symmetrically arranged on two sides of the first isolation net, the folding assemblies are arranged between the first isolation net and the second isolation net and used for driving the first isolation net and the second isolation net to turn over at relative angles, the fixing mechanisms are used for fixing the second isolation net on two sides after the first isolation net and the second isolation net on two sides turn over to form a triangle, and the locking mechanisms are used for locking the adjacent two first isolation nets. Further, the folding assembly comprises a plurality of first connecting pieces fixed on the first isolation net at intervals side by side, a plurality of second connecting pieces fixed on the second isolation net at intervals side by side, and a fixed shaft arranged between the first isolation net and the second isolation net, wherein the first connecting pieces and the second connecting pieces are sleeved on the outer peripheral side of the fixed shaft and are rotationally connected with the fixed shaft. Furthermore, both ends of the fixed shaft are fixedly sleeved with limi
