Description

The snake device is prevented in the power circuit backguy

One, technical field

The utility model relates to a kind of protector, especially the anti-snake device 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 anchor stay, i.e. the two ends of backguy are separately fixed at cement electric pole and imbed on the distaff 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 biological 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 110kv 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, the arch-criminal who causes Indonesia to have 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.

Three, utility model content

The purpose of this utility model provides the anti-snake device of a kind of power circuit backguy, 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: the snake device is prevented in a kind of power circuit backguy, its main points are: comprise circular drum, bearing, bearing pedestal, Circular Plate, collar, wherein, bearing is installed in the bearing pedestal, insert in the bearing pedestal at the two ends of circular drum, and by the bearing axial limiting, described Circular Plate is installed in the middle part of circular drum, be provided with collar in described Circular Plate both sides, described bearing, bearing pedestal, Circular Plate, collar are the circular configuration that the semicircle butt joint forms, and described circular drum axially has straight joint.

In the such scheme, described bearing centre hole inwall is provided with anti-slop serrations, and this bearing forms inner ring by the butt joint of two semicircular body end face latches, between inner ring and bearing pedestal ball is installed; Semicircle two ends at described bearing pedestal, Circular Plate, collar are provided with journal stirrup, after half and half circular shaft bearing, Circular Plate, the collar butt joint, by the fixing completely circular structure that forms of construction bolt on journal stirrup.

The utility model has the advantages that: prevent that effectively 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.

Five, embodiment

The utility model is made up of circular drum 1, bearing 2, bearing pedestal 3, Circular Plate 4, journal stirrup 5, bolt 6, collar 7, anti-slop serrations 8, latch 9.As shown in Figure 1, bearing 2 is installed in the bearing pedestal 3, insert in the bearing pedestal 3 at the two ends of circular drum 1, and by bearing 2 axial limitings, described Circular Plate 4 is installed in the middle part of circular drum 1, be provided with collar 7 in these Circular Plate 4 both sides, described bearing 2, bearing pedestal 3, Circular Plate 4, collar 7 are the circular configuration that the semicircle butt joint forms, and described circular drum 1 axially has straight joint.

By Fig. 2,3 as can be known, 2 center bore inner walls of bearing described in the present embodiment are provided with anti-slop serrations 8, and this bearing 2 forms inner ring by 9 butt joints of two semicircular body end face latches, between inner ring and bearing pedestal 3 ball is installed; After the semicircle two ends of described bearing pedestal 3, Circular Plate 4, collar 7 are provided with journal stirrup 5, half and half circular shaft bearings 3, Circular Plate 4, collar 7 butt joints, by the 6 fixing completely circular structures that form of construction bolt on journal stirrup 5.

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 circular drum 1 axially has straight joint, so earlier backguy is sticked in the circular drum 1 by the straight joint on circular drum 1 barrel, the lines made from material seal straight joint then, insert in the bearing pedestal 3 at the two ends of described circular drum 1, and by bearing 2 axial limitings, described bearing 2, bearing pedestal 3, Circular Plate 4, collar 7 is the circular configuration that the semicircle butt joint forms, and two semicircular body end faces of bearing 2 inner rings are to be bonded into by 9 pairs of latches, between inner ring and bearing pedestal 3, ball is installed, bearing pedestal 3 is that two semicircular body structures are sleeved on the bearing 2, form completely circular structure by journal stirrup 5 and bolt 6 fastening modes then, described Circular Plate 4 both sides are provided with collar 7, the Circular Plate 4 that this collar 7 forms the semicircle butt joint is fixed on the middle part of circular drum 1, described bearing 2 center bore inner walls are provided with anti-slop serrations 8, circular drum 1 is spacing, prevent circular drum 1 along backguy to lower slider.

In order to stop the destruction of snake class animal to power circuit, just must prevent the backguy of snake class animal climbing shaft tower, find by observation snake life habit, behavior and the characteristics of advancing, when snake creeps in backguy, the one, health is wrapped in the backguy, rely on the friction rotation of health and backguy to advance; The 2nd, snarl backguy with afterbody, health is S-type in backguy, rely on the friction of health and backguy to advance, and constantly adjust health S type radian, to change the weight of health in the backguy both sides, keep one's balance, stop the snake class to climb electric pole, must solve three problems along backguy: the one, stop snake to twine the backguy climbing; The 2nd, health that reduces snake and the frictional force that is touched thing; The 3rd, destroy snake and in backguy, keep EQUILIBRIUM CONDITION.

For this reason, the utility model of installing in the shaft tower backguy because of bearing pedestal 3 has sealed the two ends of circular drum 1 in synthetic, can stop snake directly to twine backguy and creep; Snake, must creep along circular drum 1 if will continue upwards to creep in the back of being obstructed, because this circular drum 1 adopts the minimum material of coefficient of friction to manufacture, snake does not almost have frictional force on circular drum 1, so increased the creep difficulty of snake on circular drum 1; Simultaneously, the middle part of circular drum 1 is equipped with Circular Plate 4, this circular drum 1 is the axle center left rotation and right rotation with the backguy, 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, diameter because of Circular Plate 4 is bigger again, when disk 3 is crossed in the snake attempt, health certainly will touch disk 3, the diameter of disk 3 is greater than the diameter of circular drum 1, increase the turning moment of circular drum 1, made circular drum 1 quicken rotation, thereby reached the purpose that prevents that snake from damaging power circuit along shaft tower backguy climbing.
