Description

A kind of anti-bird box for transmission line tower cross arm

technical field

The invention belongs to the field of power transmission line auxiliary facilities, and in particular relates to a power transmission line pole tower cross-arm bird-proof box.

Background technique

Transmission line accidents caused by bird damage occur frequently. Strengthening the operation and management of transmission lines to reduce line failures caused by bird damage is the main task. Birds reproduce quickly, and have strong adaptability and nest-loving habits. The speed of building bird nests is amazing. Surprised, it brings a great hidden danger to the transmission line. Birds like to inhabit and build nests at the hanging points of the overhead transmission poles and towers. And the droppings of birds will be connected to some insulators near the hanging point of the cross-arm insulator,

The electrical distance is insufficient and the line trips.

Conventional anti-bird devices include anti-bird thorns, anti-bird pads, sound repellent, etc. Due to the strong adaptability of birds, these devices have a short anti-bird cycle and cannot achieve the fundamental anti-bird effect. The existing anti-bird The box is a triangular box, which is installed in the place where the cross-arm birds are easy to build nests, and occupies the nesting space of birds. The overhaul of the line, and the bird-proof box that is removed during the overhaul is not easy to place as a whole.

Therefore, it is necessary to improve the existing anti-bird box, which has a good anti-bird effect, is convenient for installation and disassembly, and is convenient for placing during maintenance.

Contents of the invention

In order to overcome the problems existing in the background technology, the present invention proposes a bird-proof box with poles and towers for transmission lines, which can be easily installed and disassembled. When the line is overhauled, the disassembled bird-proof box can be folded up, which is convenient for placement and convenient for the line. overhaul.

In order to achieve the above object, the present invention is achieved through the following technical solutions: the transmission line pole and tower cross-arm bird-proof box is in the shape of a triangular prism as a whole, including two inclined surfaces, two side surfaces and a bottom surface, and the inclined surfaces and the bottom surface are rectangular epoxy resin plate, the upper edges of the two slopes are hinged together, the lower edges of the two slopes are respectively hinged with the two short sides of the bottom, the bottom is made of the same two plates hinged, and the two sides are triangular rings Oxygen resin board, fixed lines are provided on the three tops of the sides, fixed columns are provided at the hinge shafts of the two slopes and the hinge shaft ends of the slopes and the bottom surface, and the transmission line pole and tower cross-arm bird-proof box passes through the fixed card holder Fixed on the cross arm, the fixed card seat is an "F" structure composed of a "U" type card and an extension plate. The "U" type card is fixed on the cross arm angle steel by bolts, and the rivet passes through the protective plate on the bottom surface Fastened together with the extension board.

The slopes, side surfaces and bottom surfaces are all smooth surfaces, and reflective mirrors are arranged on the slopes.

Beneficial effects of the present invention: the present invention adopts a hinged structure, which enables the entire bird-proof box to be folded up, which is convenient for placement during line maintenance and saves space, and the use of a fixed card holder can facilitate the installation and disassembly of the bird-proof box, reducing labor intensity. The installation of reflectors can make the anti-bird effect better, keep the birds away from the cross-arm, and lay a solid foundation for the safe and stable operation of the transmission line.

Detailed ways

In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of technical personnel.

As shown in Figures 1-4, the present invention discloses a bird-proof box for the cross-arm of the transmission line tower. Fitted at the hanging point of the cross-arm insulator of the pole tower, it can effectively prevent birds from nesting. It mainly includes two slopes 1, two sides 3 and a bottom 2. The slope 1, side 3 and bottom 2 are all smooth surfaces, and the slope 1 And the bottom surface 2 is a rectangular epoxy resin board, which has good anti-corrosion and insulation effects. The upper edges of the two slopes 1 are hinged together, and the lower edges of the two slopes 1 are respectively hinged with the two short sides of the bottom surface 2. The bottom surface 2 is hinged by the same two boards, and the two sides 3 are triangular epoxy resin boards, which are connected by a hinged structure, so that the present invention can be folded closer to the center, which can reduce its floor space and prevent When the bird box is overhauling the circuit, it is convenient for workers to place or carry. The three tops of the side 3 are provided with fixed lines 11, and the hinge shafts of the two slopes 1 and the hinge shaft ends of the slope 1 and the bottom surface 2 are equipped with fixed columns. 9. The side 3 is a detachable structure. It can be fixed by winding the fixing wire 11 on the fixing column 9 to form a complete bird-proof box. It is necessary to remove the side when the bird-proof box is folded. As shown in Figure 2, the transmission line pole tower cross-arm bird-proof box is fixed on the cross-arm through the fixed card holder 6, which is an "F" formed by a "U"-shaped card 13 and an extension plate 12. Type structure, "U" type clip 13 is fixed on the cross-arm angle steel 7 by bolt 5, and the bird-proof box can be removed by removing the bolt 5, which is convenient and quick, saves labor and improves work efficiency, and the rivet 4 passes through the bottom surface 2 The protective plate 8 and the extension plate 12 are fixed together. The setting of the protective plate 8 is to prevent the bottom surface 2 from being damaged and deformed by the pressure of the rivets 4 directly for a long time. A reflector 10 is provided on the inclined surface 1 to prevent it from approaching the cross arm of the tower. It further plays the role of preventing birds.

The invention adopts a hinged structure, which can make the whole bird-proof box fold up, which is convenient for placing when the line is overhauled, and saves space. The anti-bird effect is better, so that the bird does not come close to the cross arm, laying a solid foundation for the safe and stable operation of the transmission line.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that it can be described in terms of form and Various changes may be made in the details without departing from the scope of the invention defined by the claims.
