Abstract

The utility model discloses a bird prevention splinter which comprises a connecting body connected with a line cross arm into a whole. Two crossed V-shaped spines are arranged above the connecting body, which take the shape of a convex arc, so that birds can not stand stably on the spines. A hollow groove is formed in the crossing position of the spines. The bird prevention splinter further comprises an inserting body with an insertion slot. The insertion slot corresponds to the connecting body in shape. In order to conveniently fix the bird prevention splinter onto the line cross arm by using a binding tape, two mounting holes with a distance of 20 to 30 mm between the centers are formed on the connecting body. The curvature radius of each spine is 130 to 140 mm; the width between the top ends of the two spines is 35 to 45 mm. Parts for the bird prevention splinter can be manufactured in advance and mounted on the site by the binding tape or glue, thereby causing convenient operation. the bird prevention splinter can be made of hard polyvinyl chloride materials the bird prevention splinter is fearless of wind, so that the utility model has the advantages of resistibility of wind and rain, corrosion resistance, high security, prevention of line short, simple structure, low cost and convenient manufacture.

Description

A kind of bird-resistant

(1) technical field

The utility model relates to transmission of electricity safety protection technique field, particularly a kind of bird-resistant.

(2) background technology

In recent years, the railway career development of China is very fast, and the electrified railway power supply circuit requires the power supply quality height, and in my office, Beijing-Shanghai, the Jiaozhou-Jinan railway has been finished electrification innovation, and He-Yan-Ri railway and Beijing-Kowloon Railway are just preparing to carry out electrification innovation at present.Safe power supply is proposed higher requirement, reason owing to natural conditions, supply line is subjected to the birds infringement serious, annual spring, birds are nested in power circuit and electrified supply line, often cause supply line's short circuit or ground connection, cause the power failure of supply line's power failure and contact line, the serious harm safety of railway transportation.

Anti-bird way of initial stage and facility: the one, strengthen making an inspection tour, but this way time and effort consuming is eliminated soon; The 2nd, take the way of improving soft environment for investment, but small bird is so not obedient, acts on too little; The 3rd, adopt products such as reflective mirror, windmill, be not durable and DeGrain; The 4th, the shutoff box that adopts galvanized iron sheet, aluminium-plastic panel to do, effect is pretty good, but because of material is the good conductor of electricity, in case occur not firm phenomenon is installed, very easily causes serious line fault; The 5th, adopt some electronics bird-scaring units, as wind energy bird-scaring unit, solar energy bird-scaring unit, but all, product has little effect because of can not conforming fully, be eliminated substantially; The 6th, with the bird-resistant of steel strand manufacturing, use the multiply steel strand wire, an end is fixed, and an end scatters, and becomes mushroom, and some effects are arranged, and is yielding but the time has been grown draw point, is deformed to a certain degree, and curassow still can dwell at this.

(3) summary of the invention

The technical problems to be solved in the utility model has provided a kind of bird-resistant, reduces the birds infringement, can effectively improve the line powering quality, guarantees safety of railway traffic.

In order to solve the problems of the technologies described above, the utility model is realized by following measure: a kind of bird-resistant comprises being used for the connector that connects as one with the circuit cross-arm that this connector top is provided with two spines that are crossed as V-type.

Above-mentioned spine is convex, and astasia is fixed in the above to make small bird.

The cross part of above-mentioned spine is provided with the groove of hollow, can block the pawl pin of bird, makes it uncomfortable.

For convenience bird-resistant is installed on the circuit cross-arm, the utility model also comprises the slotting body that is provided with insertion groove, and described insertion groove is corresponding with described connector shape.

For convenience bird-resistant is fixed on the circuit cross-arm installing hole that it is 20-30mm that described connector is provided with two centre-to-centre spacing by bandage.

Above-mentioned spine radius of curvature is 130-140mm, and width is 35-45mm between the two spine tops.

The beneficial effects of the utility model:

1. parts can be carried out in advance, only need bandage or glue just passable, easy to operate during on-the-spot the installation;

2. the utility model can adopt herd polyvinyl chloride material to make, and is not afraid of wind and weather, can not get rusty;

3. safe, adopt herd polyvinyl chloride material to make, can prevent line short;

4. comprise connector and spine, simple in structure, with low cost, easily manufactured.

Fig. 2 is the schematic top plan view of embodiment;

Fig. 3 looks schematic diagram for the left side of embodiment;

Fig. 4 is the user mode schematic diagram of embodiment;

1 connector among the figure, 2 spines, 3 insert body, 4 circuit cross-arms, a groove, b insertion groove, c installing hole.

(5) embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.Following embodiment only is used to illustrate that the utility model does not limit scope of the present utility model.

A kind of bird-resistant shown in Fig. 1 .2.3.4 comprises being used for the connector 1 that connects as one with circuit cross-arm 4 that this connector 1 top is provided with two spines 2 that are crossed as V-type; Described spine 2 is convex; The cross part of described spine 2 is provided with the groove a of hollow; Described spine 2 radius of curvature are 130-140mm, and width is 35-45mm between two spines, 2 tops.

For convenience bird-resistant is installed on the circuit cross-arm, also comprises the slotting body 3 that is provided with insertion groove b, described insertion groove b is corresponding with described connector 1 shape.

For convenience bird-resistant is fixed on the circuit cross-arm installing hole c that it is 20-30mm that described connector 1 is provided with two centre-to-centre spacing by bandage.

The utility model can bundle separately to be installed or the slotting body installation of utilization, and installation process is as follows:

When (1) installing separately, penetrate earlier among the installing hole c, be held together with circuit cross-arm 4 again, and the cross part of spine 2 is kept upright and is firmly made progress with bandage; Require to keep between the adjacent bird-resistant center line distance of 125-135mm.

(2) when inserting body 3 and install, earlier slotting body 3 is firmly tied up on circuit cross-arm 4, and insertion groove b is upright, then equidirectional bird-resistant in turn in the insertion groove b, and be inserted into the bottom, then adhesive is splashed into 2-3 toward socket groove b and drip, make it to cohere firm; When docking between two slotting bodies, make the identical distance of maintenance between respective socket.
