Description

The snake cover is prevented in the power circuit backguy

One, technical field

The utility model relates to a kind of protector, the snake cover is prevented in especially a kind of power circuit backguy.

Two, background technology

China's electric power line pole tower is mainly two kinds: a class is an iron tower; One class is a cement pole.In when using the power circuit of cement pole, in order to keep the stable of cement pole, the Horizontal Tension of equalizing contactor and corner stress generally adopt low anchor backguy, i.e. the two ends of backguy are separately fixed at cement electric pole and imbed on the stay rod on ground.Electric power line pole tower is distributed in field, particularly power transmission sequence usually, and it passes through high mountain high hill, rivers and lakes, running environment is very complicated, very easily suffers the destruction of toys such as birds, snake class, in recent years, along with the continuous improvement of ecological environment, power circuit toy activity along the line is very active.According to statistics, certain power supply administration in 2005 has jurisdiction over the 110KV circuit because of the snake class causes 2 of line tripping accidents, accounts for 25% of line fault then, and line facility is destroyed, and has a strong impact on the safe operation of electrical network.According to another the interrelated data introduction, meeting with into the arch-criminal that Indonesia has a power failure on a large scale is exactly a snake.Since when power circuit designs, do not consider the snake class by way of backguy, the situation of discharge initiating failure when road gold utensil, insulator are near live wire along the line, so, do not prevent the measure that this type of accident takes place.

Chinese patent application number is the anti-snake devices of 200520010658.7 described power circuit backguys, though, be installed in power line and can prevent that snake class animal from arriving the destruction of the head of the mast to power circuit, complex structure along the power circuit backguy, make difficulty, install inconvenient.

Three, utility model content

The purpose of this utility model provides the anti-snake cover of power circuit backguy a kind of simple in structure, easy for installation, prevents that the backguy of snake class animal climbing power circuit from arriving the destruction of the head of the mast to power circuit.

Concrete scheme of the present utility model is: design the anti-snake cover of a kind of power circuit backguy, comprise the cylinder that axially has straight joint, its main points are: the two ends at described cylinder are snapped with end cap, this end cap radial direction has groove to the center, be equipped with by two card line covers rounded in end cap central authorities the cross section that is bonded into, in described end cap inboard or arranged outside the locating piece that is made of two butt joints is arranged.

Described card line cover is " T " butt joint by two sections and is formed with the through hole column sleeve of step, and an end diameter of card line cover that wherein is positioned at the end cap inboard is greater than the diameter that passes the end cap central bore part.This card line is enclosed within the end cap central bore, is convenient to the electric power backguy is limited in the end cap central bore, prevents that the radial slot that the electric power backguy goes out end cap from skidding off.

The rectangular block butt joint that described locating piece is a half-arc groove by two centers constitutes, and the butt joint of two half-arc grooves forms a circular hole, and this circular hole is the axially extending bore of locating piece, i.e. the central through hole of locating piece.On the locating piece of described circular hole upper and lower position, have screw, two rectangular blocks are linked together by screw.Locating piece is set in the end cap side that is positioned at cylinder two can prevents that cylinder and end cap from sliding along the electric power backguy.

The beneficial effects of the utility model are: simple in structure; install, make all very convenient; can prevent effectively that the backguy of snake class animal climbing power circuit from arriving the destruction of the head of the mast to power circuit; reduce power grid accident; improve electric network security; simultaneously positive meaning has been played in the protection of snake class animal, had fairly obvious economic benefit and social benefit.

Four, description of drawings:

Fig. 1 is that the utility model is installed in the user mode reference diagram on the power line;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the C-C sectional view of Fig. 2;

Fig. 4 is that the B of Fig. 1 is to enlarged drawing;

Fig. 5 is the left view of locating piece 4 among Fig. 4.

Five, the specific embodiment:

Please see Figure 1, Fig. 2, Fig. 3, Fig. 4, the utility model mainly is made up of end cap 1, cylinder 2, card line cover 3, locating piece 4, filler rod 6, wherein, on cylinder 2, axially have straight joint, be snapped with end cap 1 at the two ends of described cylinder 2, this end cap 1 radially has groove to the center, be equipped with by two card line covers 3 rounded in end cap 1 central authorities the cross section that is bonded into, in described end cap 1 inboard or arranged outside the locating piece 4 that is made of two butt joints is arranged, the centre bore of the central through hole of this locating piece 4 and end cap 1 is corresponding and communicate.

As can be seen from Figure 3: described card line cover 3 is the through hole column sleeve that " T " butt joint is formed with step by two sections, and an end diameter of card line cover 3 that wherein is positioned at end cap 1 inboard is greater than the diameter that passes end cap 1 centre bore part.

As shown in Figure 3, Figure 4: the rectangular block butt joint that described locating piece 4 is a half-arc groove by two centers constitutes, the butt joint of two half-arc grooves forms a circular hole, this circular hole is the axially extending bore of locating piece 4, on the locating piece 4 of described circular hole upper and lower position, have screw, two rectangular blocks are linked together by screw.

As can be seen from Figure 2: " worker " font filler rod is installed at the straight joint place of described cylinder 2.After straight joint is enclosed within on the power line, filler rod 6 is contained in the straight joint place of cylinder 2 at cylinder 2, appearance looks elegant not only, and can prevent that power line from exposing outside the cylinder 2.

The utility model is work like this: in using process of the present utility model, because of fixing at the two ends of present existing shaft tower backguy, the dismounting backguy is very difficult, and it is dangerous, because of radially having groove on the end cap 1, can load onto card line cover 3 earlier half at end cap 1 inwall center, again earlier with backguy by the radial slot on the end cap 1 is sticked in the end cap, then second half card line cover 3 is installed with screw, the electric power backguy is enclosed in the card line cover 3, then, in the electric power backguy between the two end cap 1, backguy is sticked in the circular drum 1 by the linear slit on circular drum 1 barrel, seal straight joint on the cylinder 2 with filler rod 6 again.Two end cap 1 is snapped onto cylinder 2 two ends, respectively at end cap 1 outside installing and locating piece 4, that circular drum 1 is spacing in backguy at last, prevent that circular drum 1 is to lower slider.Since cylinder 2 and end cap 1 be kink in backguy, when snake is twined backguy when creeping, cylinder 2 and end cap 1 rotation, and snake must creep along circular drum 1, thereby increased the creep difficulty of snake on circular drum 1; Left rotation and right rotation will take place when snake crawls on the circular drum 1, destroy the balance condition that snake keeps when creeping, again because of the diameter of end cap 1 diameter greater than circular drum 2, increased the turning moment of circular drum 1, make circular drum 1 quicken rotation, thereby reach the purpose that prevents that snake from damaging power circuit along shaft tower backguy climbing.
