Abstract
The utility model discloses a transmission line bird-preventing baffle, which adopts a rectangular baffle on which a round hole is arranged in the center; a through installing groove from the middle part of one side of the baffle to the round hole part in the center is arranged on the baffle; and a locking mechanism for fixing the baffle on the metal bar arranged at the upper end of the insulator can be arranged on the baffle surface. The baffle can effectively prevent the bird nest on the crossarm from being fallen on the insulator due to the stormy weather so as to cause the short circuit, and also can prevent the birds from staying at the crossarm and crapping heavy, so as to cause the heavy pollution for the insulator and the circuit pollution flashover and tripping operation; thus reducing the intensity and cost of the operation and maintenance, and improving the reliability of the transmission line operation.

The utility model content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of transmission line safely and effectively to prevent the bird baffle plate, can effectively prevent the insulator short circuit that causes because bird is nested on cross-arm.
The utility model technical solution problem adopts following technical scheme:
Transmission line is prevented the bird baffle plate, adopt central authorities to open the rectangle baffle plate of circular hole, on described baffle plate, offer the mounting groove of perforation, and the face of baffle plate is provided with the retaining mechanism on the Metallic rod that described baffle plate can be fixed in the insulator upper end from baffle plate middle part on one side to the circular hole place of central authorities.
Design feature of the present utility model also is:
Described retaining mechanism comprises, be installed in a pair of channel-section steel that is positioned at described circular hole both sides on the baffle plate by bolt, the trend of two channel-section steels moves towards parallel with described mounting groove, also comprise two angle steel, wherein the two ends of an angle steel are separately fixed on the end face of two channel-section steels, one end of another root angle steel is fixed therein on the end face of a channel-section steel, the other end of this angle steel and another root channel-section steel flexibly connect and lockable, two channel-section steels and two angle steel surround one " mouth " font square frame jointly, the axis of this square frame overlaps with the axis of described circular hole, is welded with opening respectively towards relative circular arc fastener on two angle steel, two limits in opposite directions.
Be provided with a secondary baffle plate that described mounting groove can be covered, an end of described secondary baffle plate is by being bolted on the baffle plate, and the other end is fixed on segment length's bar shaped channel-section steel, and the strip channel-section steel is by being bolted on the baffle plate.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is by the anti-bird baffle plate of fixed installation on the Metallic rod of insulator upper end, can prevent effectively that the Bird's Nest on the cross-arm from causing short circuit on the insulator because of wind and rain weather drops to, can prevent that also bird from staying and a large amount of defecation on cross-arm, insulator is caused pollution severity, cause the tripping operation of circuit generation pollution flashover, thereby reduce the intensity and the cost of operation maintenance, improve the transmission line reliability of operation.
Description of drawings:
Fig. 1 is the structural representation that anti-bird baffle plate of the present utility model is installed in the insulator upper end, retaining mechanism and the secondary baffle plate of anticipating out not shown in the figures.
Fig. 2 A is baffle plate and the structural representation that is installed in the retaining mechanism on the baffle plate.
Fig. 2 B is the structural representation of secondary baffle plate.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, the transmission line of present embodiment is prevented the bird baffle plate, adopt central authorities to open the rectangle baffle plate of circular hole, on the face of baffle plate 1, offer the mounting groove 2 of perforation to the circular hole place of central authorities from baffle plate middle part on one side, referring to Fig. 2 A, Fig. 1, the face of baffle plate is provided with the retaining mechanism 4 on the Metallic rod 3 that described baffle plate 1 can be fixed in the insulator upper end, retaining mechanism comprises: a pair of channel-section steel 5, they are by being bolted to the both sides that are positioned at circular hole on the baffle plate 1, the trend of two channel-section steels moves towards parallel with described mounting groove 2, also comprise two angle steel 61 and 62, wherein the two ends of an angle steel 61 are respectively by on the end face that is bolted to two channel-section steels, one end of another root angle steel 62 is by bolt therein on the end face of a channel-section steel, the other end of this angle steel 62 and another root channel-section steel flexibly connect and lockable, flexible connection and locking are achieved in that the side perforate of angle steel 62, and the end face of the channel-section steel that is connected with this angle steel 62 can pass and use latch locking from this hole; Two channel-section steels and two angle steel surround one " mouth " font square frame jointly, the axis of this square frame overlaps with the axis of described circular hole, be welded with opening respectively towards relative circular arc fastener 9 on two angle steel, two limits in opposite directions, circular arc fastener 9 is connected on the Metallic rod 3.Shown in Fig. 2 B, in order to prevent that Bird's Nest or birds droppings from hanging to insulator from mounting groove 2, also be provided with secondary baffle plate 7, one end of secondary baffle plate 7 can be fixed on the baffle plate 1 by bolt or latch, the other end of secondary baffle plate is fixed on the strip channel-section steel 8, and strip channel-section steel 8 can be fixed on the baffle plate 1 by bolt or latch.
During installation, earlier on the ground with a pair of channel-section steel 5 by being bolted on the baffle plate 1, wherein an angle steel 61 is by being bolted on two channel-section steels, end with another root angle steel 62 passes through the bolt pretension on channel-section steel again, secondary baffle plate 7 is fixed on the strip channel-section steel 8 by crab-bolt, above-mentioned article and erecting tools are brought on the electric power pylon, baffle plate 1 is installed on the Metallic rod 3 of insulator 10 and cross-arm 11 junctions by mounting groove 2, fastener 9 is connected on the Metallic rod 3, with latch angle steel 62 is locked on the channel-section steel, baffle plate 1 just is locked on the Metallic rod of insulator top like this, again an end of secondary baffle plate 7 is fixed on the baffle plate 1 by latch, strip channel-section steel 8 is connected on the limit of baffle plate 1 and with latch and fixes, and the whole erection process is finished.During concrete the making, it is that 5 centimetres clear polycarbonate is made that baffle plate 1 and secondary baffle plate 7 can adopt thickness, metal parts such as channel-section steel, angle steel can adopt stainless steel and hot-dip galvanizing sheet steel to make, there is not the situation of getting rusty, because baffle plate is transparent, check the insulator situation after convenient, need not take off the situation that just can see following insulator to baffle plate.
