Accordingly, the fastening member (bolt) is inserted through the hole is fastened to the hole of the wrought iron (2), so that the wrought iron mounting bracket 10 is firmly fixed to the wrought iron (2). On the other hand, the complete installation bracket 10 is very useful when it is necessary to further install the insulator 20, as shown in Figure 6 can change the position as needed.

The insulator 20 is an insulator used to insulate the spiral portion of the overhead wire L and simultaneously maintain or support it mechanically, and is fixed to an upper surface of the bracket for installation of wrought iron 10. In particular, the installation groove 21 is formed in the center of the upper surface of the insulator 20, the air cylinder 32a of the first buffer member 32 described later is inserted into the installation groove 21. In addition, a screw tab is formed on the inner circumferential surface of the installation groove 21 so that the fastening portion 31b of the vibration damping device 30 can be easily fastened.

The vibration damping device 30 is composed of a vibration damping device main body 31, the first shock absorbing member 32, the wire holding member 33 and the second shock absorbing member 34. The vibration damping device 30 is severely swung left and right and up and down when the processing wire L is subjected to wind pressure (wind power), which is transmitted to the insulator 20 by elastically attenuating the load and the vibration caused by the rocking. Serves to prevent this.

The vibration damping device main body 31 is formed as a U-shape as a whole, using an insulating material. Guide parts 31a are formed on both sides in the longitudinal direction, and a fastening part 31b having screw tabs formed on an outer circumferential surface thereof is formed at the center of the bottom so as to be mutually fastened to the installation groove 21 of the insulator 20. A fixing part 31c provided with a groove is integrally formed at both left and right ends of the coupling part 31b so that the lifting part 81 of the solenoid 80 may be inserted and fixed. In particular, the center of the fastening portion 31b penetrates up and down because the cylinder rod 32b of the first buffering member 32 is elevated.

The first shock absorbing member 32 is a known air spring consisting of an air cylinder 32a filled with air therein and a cylinder rod 32b which is installed to be liftable on the air cylinder 32a. It is a mechanism for receiving (absorbing) the vibration up and down of the processing wire (L) by the transmission wire to prevent the transfer to the insulator (20). In particular, the wire fixing part (32b-1) for fixing the processing wire (L) is installed on the upper surface of the cylinder rod (32b), the installation method is to force the processing wire (L) by pushing the fixed between the cut grooves do.

The wire retaining member 33 is a mechanism that is movable to the guide portion 31a. In particular, both sides of the wire retaining member 33 is formed with a wing piece (33a) protruding outward is to be inserted into the guide portion (31a) can be installed to be movable. The wire holding member 33 can also easily fix the processing wire (L) through a cut formed in the center.

The second shock absorbing member 34 is the same air spring as the first shock absorbing member 32. If the first shock absorbing member 32 is a device for receiving (absorbing) up and down vibrations, the second shock absorbing member 34 may be used. Is a device that receives (absorbs) vibrations in the horizontal direction (length direction) from side to side. The configuration is also composed of the air cylinder 34a and the cylinder rod 34b in the same manner as the first buffer member 32. The second shock absorbing member 34 is fixed between the air cylinder 34a and the end of the cylinder rod 34b between the blade pieces 33a of the pair of wire retaining members 33 via pins.

Since the vibration damping device 30 is a device for supporting the processing wire L through which electricity flows, it is preferable to manufacture the insulating material.

The correlation between the wind direction generator 40, the controller 50, the switch unit 60, the battery 70, and the solenoid 80 will be described with reference to FIG. 6.

The wind generator 40 has a rotation shaft 41 and a hemisphere 42 installed on the rotation shaft 41 to produce electromotive force through the rotation shaft 41 that is rotated by the wind force applied to the hemisphere 42. To the controller 50. Since technical matters of the wind direction generator 40 are already known, a detailed description thereof will be omitted.

The controller 50 receives the electromotive force from the wind direction generator 40 to turn on the operation of the switch unit 60 when it exceeds the reference value.

The battery 70 is a vehicle battery, and the battery 70 needs only to have power enough to operate the solenoid 80.

The solenoid 80 is a device for operating the vibration damping device 30 is operated by the power supplied from the battery 70. The solenoid 80 is provided with an elevating portion 81 that is elevated by power, and the elevating portion 81 is inserted into the groove of the fixing portion 31c disposed on the bottom surface of the vibration damping device 30 as the elevating portion 81 is shot. It is firmly fixed and supported.

According to an exemplary embodiment of the present invention, when the strong wind blows the processing wire L, the insulator 20 alone may not support the vibration damping device 30 alone, and may be severely broken. In this case, by auxiliaryly fixing and supporting the vibration damping device 30 through the aforementioned wind direction generator 40, controller 50, switch unit 60, battery 70, solenoid 80, It is possible to prevent the insulator 20 from being damaged.

Referring to Figure 1, the transformer 90 is a known device for converting high-voltage power into commercial power, is installed on the outer surface of the pole (1) via a fixing means such as a fixing band. In particular, the transformer 90 is provided with a lead wire (L ') is electrically connected to the overhead wire (L), and a lead wire (L ") is electrically connected to the breaker 102 of the switchboard main body 100. In the case of the transformer 90, a detailed description thereof will be omitted.

Referring to FIG. 5, the switchboard main body 100 includes a case part 101, a breaker 102, an outlet 103, an illumination switch 104, and a lamp 105. It is fixed to the support body 2-1 of 2).

The case part 101 is an enclosure of an insulating material, and generally has a rectangular box shape, and a door part 101a is installed on the front surface of the case so as to open and close the inside. In particular, the light switch 104 protruding forward is installed on a surface which is in close contact with the door 101a when the door 101a is closed. Therefore, when the operator opens the door 101a, the lamp 105 is supplied with power to emit illumination light, and when the door 101a is closed again, the power supplied to the lamp 105 is switched. By being blocked by the unit 104, the illumination light of the lamp 105 is turned off.

The breaker 102 is installed in the case unit 101 and is electrically connected to the lead wire L ″ drawn from the transformer 90 to connect and cut off the power supply to the outlet 103 and the light switch 104. In addition, there is an advantage that can protect the switchboard main body 100 from the fire caused by the waste of unnecessary power and short circuit by automatically blocking the occurrence of a short circuit occurs when an error occurs in the wire.

The outlet 103 is installed in the case portion 101, and is a kind of connection device that is connected to the breaker 102 so that power can be supplied to the plug (not shown) of the tool connected thereto.

As mentioned above, the case unit 101 is provided with an illumination switch 104 and a lamp 105, respectively, and the description of the above operation has already been described above, and thus description thereof will be omitted.

Referring to the operation of the present invention made of the configuration as described above are as follows.

When the weak wind blows in the installed state, as shown in Figure 1, the movement of the processing wire (L) is weakly swayed left and right (length direction) and up and down.

In this case, as shown in Figures 3 and 4, the vibration transmitted up and down is accommodated (absorbed) by the first buffer member 32 of the vibration damping device 30, the vibration transmitted in the longitudinal direction is the second buffer The member 34 is accommodated (absorbed).

In more detail, when the first shock absorbing member 32 vibrates up and down, the cylinder rod 32b is lowered to the air cylinder 32a together with the up and down of the processing wire L. And it is possible to accommodate (absorb) vibration by compressing and relaxing the air therein while repeating the lifting and lowering.

In addition, in the case of the second buffer member 34, a pair of wire holding members 33 holding the processing wire L move along the length direction due to the oscillation in the left and right (length directions). The air cylinder 34a and the cylinder rod 34b of the two-buffer member 34 receive (absorb) vibration in the longitudinal direction while repeating compression and relaxation.

On the other hand, when the typhoon blows the processed wire L severely, the insulator 20 cannot be tolerated by the vibration damping device 30 alone. At this time, the wind direction generator 40, the controller 50, and the switch unit 60 The battery 70 and the solenoid 80 can be prevented from shaking.

In more detail, when the hemisphere 42 of the wind direction generator 40 hits the wind, the rotating shaft 41 connected to the hemisphere 42 rotates, thereby generating an electromotive force, and the generated electromotive force is It is delivered to the controller 50.

When the electromotive force exceeding the received electromotive force is compared with the reference value and the electromotive force is output, the controller 50 operates the switch 50 immediately so that the power of the battery 70 is transmitted to the solenoid 80.

Then, the solenoid 80 is energized to cause the lifting unit 81 to be shot, and the tip of the shot lifting unit 81 is a groove of the fixing unit 31c disposed on the bottom of the vibration damping device 30. Since it is inserted into and firmly fixed and supported, the insulator 20 to which the vibration damping device 30 and the vibration damping device 30 are connected by the strong wind can be prevented from being broken and damaged.

If the insulator 20 is damaged due to the strong wind and needs to be repaired due to the malfunction of the insulator 20, the operator may carry the tool while carrying the tool on the electric pole 1 in the state of the switchboard main body 100. Open the door 101a, connect the plug of the required tool to the outlet 103, and repair and replace the insulator 20 through the tool. Furthermore, even when the insulator 20 is urgently repaired at night, when the door 101a of the switchboard main body 100 is opened, the light switch 104 is fired and the power is connected to the lamp 105 to supply power. Since the received lamp 105 illuminates the surroundings, the operator can also find the outlet 103 very easily and use the tool.

On the other hand, when the wind is quieted to some extent and the electromotive force output from the wind direction generator 40 is less than the reference value, the switch 50 is operated again to release the connection state, thereby raising and lowering the lifted solenoid 80. 81 loses its function and is lowered to release the fixed state.

Furthermore, since the vibration damping device 30 is operated accordingly when the processing wire L is relaxed or contracted in summer and winter, it is possible to prevent damage to the processing wire L due to changes in weather. It also has advantages.

As shown in FIG. 7, when the insulator 20 needs to be further provided on the upper surface of the finished iron 2 or when the gap between the processing wires L is narrow and there is a possibility of mutual interaction with the wind, the finished iron 2 ) And the rebar mounting bracket (10) in the state of releasing the fastening member (bolt) is fastened to each other and the rebar mounting bracket (10) by adjusting the length direction of the rebar (2) as appropriate.
