1 is a cross-sectional view of the insulator to prevent the derailment of the distribution line according to the invention, Figures 2 to 3 is a reference diagram for explaining the operation of the insulator to prevent the derailment of the distribution line according to the present invention.

1 to 3, the insulation insulator for preventing derailment of the distribution line according to the present invention is applied to the insulation insulator when the external force is applied to the main body 10 made of a ceramic material and the main body 10. The moving part 20 and the main body 10 and the moving part 20 to reduce the impact of rotation, and the rotating table 30 and the main body 10 and the moving part 20 for rotatably fixing the main body 10 and the moving part 20 to one another. When the body 10 is rotated so as not to directly contact the wrought iron 1 and includes a shock absorbing member 40 for cushioning the shock applied to the body 10 and the moving part 20.

In the case of the main body 10, due to external stress caused by climate change such as thermal stress, wind, snow, and ice due to the difference in temperature and the effect of air pollutants such as ultraviolet rays, dust, industrial dust and salts and the temperature change while high voltage is applied. Due to mechanical stress such as thermal expansion and contraction between dissimilar materials, the deterioration progresses gradually, and thus durability and contamination resistance should be excellent. Therefore, the body 10 is preferably made of a ceramic material, it can be manufactured even using a polymer material. The shape of the main body 10 is a shape in which the hat shape is overlapped in a normal insulator shape, and can be manufactured in various shapes according to the use purpose. In addition, the main body 10 is formed with a through hole having a shape corresponding to the cross-sectional shape of the cylinder 21.

The moving part 20 is inserted into the through-hole formed in the main body 10, and the cylinder 21 for guiding the vertical movement of the piston 22, and the piston 22 which is movably installed in the inside of the cylinder 21 are shown. And, it is fixed to the upper surface of the piston 22, the moving table 23 for transmitting the up and down movement of the piston 22 to the fastening table 24, and fixedly installed on the upper end of the moving table 23, the distribution line (L) It includes a fastener 24 for fixing by fastening.

The cylinder 21 is typically used in an engine or the like, and its basic function is similar to a cylinder in which a piston reciprocates. That is, in order for the piston 22 to move up and down inside, a hollow 21e having a shape corresponding to the outer shape of the piston 22 is formed, and the outer shape of the cylinder may be a rectangular frame shape or a cylindrical shape. The first through-hole 21c through which the first through-hole 21a and the moving table 23 penetrates is formed in the upper surface of the cylinder 21, and the second through-hole 21b and the fixing stand 25 penetrate through the lower surface. 21 d of two through-holes are formed. The first through hole 21c is formed on the upper surface of the cylinder 21 so as to correspond to the cross-sectional shape of the movable table 23 so as to pass through the outside of the cylinder 21 and the hollow 21e, and thereby the movable table 23. Is able to move up and down as the piston 22 moves. The second through hole 21d is formed in the lower surface of the cylinder 21 so as to correspond to the cross-sectional shape of the holder 25 so as to pass through the outside of the cylinder 21 and the hollow 21e, and the holder 25 is formed through the second through hole. It moves up and down through the hole 21d.

The first vent 21a and the second vent 21b are air in the hollow 21e due to the movement of the piston 22 when the piston 22 is in close contact with the hollow 21e of the cylinder 21 and moves up and down. Discharge to the outside to smooth the vertical movement of the piston (22). When the first vent 21a and the second vent 21b are too large, the air inside the hollow 21e is discharged so easily that the piston 22 easily moves without great resistance inside the hollow 21e, and when it is too small Since the air inside the hollow 21e is hardly discharged, the movement of the piston 22 is hardly made. Therefore, the first vent 21a and the second vent 21b should be formed so that the piston 22 can move while receiving a resistance of an appropriate air pressure.

The piston 22 is made of a synthetic resin material of high strength, and a thin film 22a formed of a rubber material is formed on an outer surface thereof. The piston 22 is installed to be movable in close contact with the outer surface of the hollow 21e, and when the friction force between the membrane 22a and the outer surface of the hollow 21e is large and difficult to move, or when the piston 22 is not completely in contact with the lubricant, In addition, the film 22a and the hollow 21e can be brought into close contact with each other to smoothly move, thereby preventing air from leaking out.

The movable table 23 has a rod shape, and a lower end thereof is fixed to the upper surface of the piston 22, and a fastening table 24 is fixed to the upper end thereof. When the external force is applied to the distribution line L, the movable table 23 transmits the applied external force to the piston 22 so that the piston 22 moves up and down.

The fastening table 24 is fixedly installed on the upper end of the moving table 23, and is fastened by fixing the distribution line (L). Fastening table 24 is applicable to a variety of structures that can be fixed by fastening the distribution line (L). As an example, the pipe may be formed in a tubular shape, and then the power distribution line L may be inserted into the pipe and then fastened by using a bolt or the like.

The holder 25 is rod-shaped, and one end is fixed to the lower end of the piston 22 and is installed to penetrate through the second through hole 21d. The other end of the fixing stand 25 is inserted into and fixed to the fixing groove 1a formed on the upper surface of the cast iron 1 in accordance with the vertical movement of the piston 22, and when inserted into the main body 10 and the moving part 20 Prevent rotation.

The rotating table 30 fixes the main body 10 and the moving part 20 to the wrought iron 1 through the rotating shaft 1b. One end of the rotating table 30 is fixed to the lower surface of the cylinder 21, and the other end is rotatably installed through the cylindrical rotating shaft 1b fixed to the wrought iron 1.

The shock absorbing member 40 is fixed to the lower surface of the cylinder 21 to be inclined in the outward direction of the main body 10 in the shape of an inclined cylindrical or square frame made of rubber material so as to act as a buffer. In addition, the other end of the shock absorbing member 40 is spaced apart from the upper surface of the wrought iron 1 by a predetermined distance. When the main body 10 and the moving part 20 are rotated, the main body 10 made of ceramic material may collide with the corner portions of the wrought iron 1 made of metal and may break. In addition, the main body 10 and the moving part 20 may be impacted by being bumped with the wrought iron 1, and the main body 10 is broken or the main body 10 and the moving part 20 when the shock is continuously received. ) Weakened coupling may be separated from the main body 10 and the moving part (20). When the main body 10 and the moving part 20 are rotated, the shock absorbing member 40 comes into contact with the wrought iron 1 before the main body 10 touches the wrought iron 1 so that the main body 1 is wrought. Not to collide with, and also made of a rubber material to mitigate the impact caused by the impact of the shock absorbing member 40 and the wrought iron (1) transmitted to the body 10 and the moving part (20). In addition, the buffer member 40 is fixedly installed only on the lower surface of the cylinder 21 so that the impact is not directly transmitted to the body (1).

Referring to Figures 2 to 3 will be described the operation of the insulator to prevent the derailment of the distribution line according to the present invention.

When an external force is applied from the bottom to the top of the power distribution line L inadvertently during an operation using an excavator, a crane, or the like, the external force applied to the power distribution line L is connected to the piston through the fastening table 24 and the moving table 23. 22, the piston 22 is moved upward by the external force. The force is applied in the diagonal direction upward of the fastening table 24 by the tension of the distribution line L facing in the external force direction and the force of the external force in the upward direction, but the piston 22 cannot move left and right, but only shanghai-dong. Because it can move upwards. The raising of the piston 22 increases the air pressure inside the hollow 21e, and the raising action of the piston 22 is buffered by the increased air pressure. In addition, the upward movement of the piston 22 is continued while the air inside the air escapes through the air vent 21a to the outside of the hollow 21e by the increased air pressure in the hollow 21e. As the piston 22 rises, the amount of impact applied to the connection portion between the distribution line L and the insulator is reduced, thereby increasing the stability of the coupling between the distribution line L and the insulator, the insulator and the insulator (1). do.

As the piston 22 is lifted, the holder 25 fixed to the piston 22 is also raised, and the holder 25 is fixed to the fixed groove 1a formed in the cast iron 1 by the lift of the holder 25. The bond is released. When the insertion of the holder 25, which prevents the rotation of the main body 10 and the moving part 20, is released, the main body 10 and the moving part 20 become rotatable and are applied upward to the distribution line L. The tension of the distribution line L is increased by the external force, and the main body 10 and the moving part 20 are rotated in the direction in which the external force is applied by the increased tension. The rotation as described above can reduce the increased tension to prevent the coupling between the distribution line (L) and the insulator and the insulator and the cast iron (1) is weakened or released.

In addition, when the main body 10 and the moving part 20 rotate, the end of the shock absorbing member 40 installed inclined in the outward direction of the main body 10 at the lower end of the cylinder 21 is completed before the main body 10. It comes into contact with the upper surface of. The shock absorbing member 40 prevents the main body 10 from contacting the wrought iron 1 and buffers the shock applied to the main body 10 and the moving part 20. In addition, the shock absorbing member 40 is installed at the lower end of the cylinder 21, so that the direct impact through the shock absorbing member 40 is not transmitted to the main body 10, but only to the cylinder 21, the main body 10 made of a ceramic material. It is effective to protect more stably.
