Description

TECHNICAL FIELD

[0001] The present application relates to the field of power equipment, in particular to a power line external force monitoring and early warning device and method. BACKGROUND

[0002] The power line is a conductor loop connecting the transformer substation and distribution station with each power user or electrical equipment, and transmitting and distributing electric energy from the power supply end (transformer substation and distribution station) to the load end (power user or electrical equipment). The power line is divided into high-voltage line and low-voltage line according to voltage. The high-voltage line refers to the power line with voltage of 1kV and above, and the low-voltage line refers to the power line with voltage below 1kV. Some people call the power line with voltage of 1kV to 10kV or 35kV as medium-voltage line, and call the power line with voltage of 35kV above to 110kV or 220kV as high-voltage line, and call the power line with voltage of 220kV or 330kV above as extra-high-voltage line.

[0003] One of the most common damage reasons of the power line in winter is that the wire is broken due to over heavy external force caused by ice on the wire. Since the connection between the wire and the pole is the bearing point of the wire, the most common breaking point is the connection between the wire and the pole. Once the wire is broken, it will cause a large area power outage accident, which will affect production and life. Therefore, how to early warn and buffer when the wire bears over heavy external force due to ice on the wire to prevent the wire from breaking becomes an urgent problem to be solved. SUMMARY

[0010] Preferably, the early warning mechanism comprises: a steel wire rope which is fixedly connected with the wire disc at one end, the steel wire rope being wound on the wire disc; a second sliding block which is fixedly connected with the second sliding block at the other end, the steel wire rope penetrating through the support pipe and the through hole and being fixedly connected with the second sliding block; a second sliding rail which is fixedly connected with the buffering column, the second sliding block being slidably connected on the second sliding rail; a left limiting block which is fixedly connected with the left end of the second sliding rail; and a self-resetting control button which is fixedly arranged on the right side of the second sliding rail, the self-resetting control button being wirelessly connected with the alarm.

[0011] Preferably, the early warning mechanism further comprises: a sliding cylinder which is slidably sleeved on the front support and the rear support, the second sliding block being fixedly connected with the sliding cylinder through a connecting column.

[0012] Preferably, one end of the electric wire close to the electric pole is in a wavy shape, the one end of the electric wire close to the electric pole is slidably sleeved with a sliding ring, the sliding ring is fixedly connected with the front support and the rear support through a fixing rod, a third spring is sleeved on the electric wire, one end of the third spring is fixedly connected with the sliding ring, the other end of the third spring is fixedly connected with a fixing ring, and the fixing ring is fixedly sleeved on the electric wire.

[0015] The beneficial effects of the present application are:

[0016] 1、The multiple buffer warning mechanisms of the present application compress and fix the electric wire, achieving multi-point fixing of the electric wire. Compared with the original fixing method in which the electric wire is only connected with the electric pole, the fixing effect is better. When the electric wire is iced, as the amount of ice increases, the ice wrapped outside the electric wire presses the electric wire, the originally curved electric wire in the buffer column is gradually straightened, the support pipe is pushed, and the electric wire is gradually pulled out of the buffer column. This not only effectively buffers the pressure on the electric wire caused by icing, but also effectively delays the stress on the connection between the electric wire and the electric pole, effectively preventing the electric wire from breaking.

[0017] 2、When the electric wire in the buffer column is straightened and pulled out of the buffer column, the wire driving reel rotates to wind the steel wire rope on the reel, so that the steel wire rope moves the second sliding block to press the self-resetting control button, the self-resetting control button starts the alarm to alarm, reminding the staff that the electric wire at this position is under pressure and needs to be repaired.

[0018] 3、When the electric wire in the buffer column is straightened, the support pipe is extruded to the outside of the buffer column, so that the support pipe extrudes the first spring through the buffer rod, thereby playing a buffering role in the process of straightening the electric wire.

[0019] 4、When the electric wire in the buffer column is completely straightened, the electric wire pushes the buffer column to move through the first limiting block, so that the buffer column extrudes the first spring through the support pipe and the buffer rod to buffer.

[0020] 5、When the electric wire in the buffer column is completely straightened, the end of the electric wire close to the electric pole is in a wave shape, and the electric wire in a wave shape at this position is not stressed before being straightened.

[0021] 6、When the ice on the electric wire is removed, and the electric wire is no longer under external force, the first spring moves to extrude the electric wire by driving the support pipe into the buffer column through the buffer rod and the sleeve under the elastic force of the first spring, so that the electric wire in the buffer column is bent again, thereby preparing for the next time the electric wire is stressed.

[0035] Working principle: when the electric wire 7 is iced, with the increase of the icing amount, the ice wrapped outside the electric wire 7 presses the electric wire 7 downwards, the originally curved electric wire 7 in the buffer column 5 is gradually straightened, the support pipe 24 is pushed out of the buffer column 5 by the wire reel 36 and the support plate 35 in the process of the electric wire 7 being straightened, and the electric wire 7 is gradually pulled out of the buffer column 5, which not only effectively buffers the pressure on the electric wire caused by icing, but also effectively delays the stress on the connection between the electric wire 7 and the electric pole 1, effectively preventing the electric wire from being broken. When the electric wire 7 in the buffer column 5 is straightened and pulled out of the buffer column 5, the electric wire 7 drives the wire reel 36 to rotate, so that the wire reel 36 winds the steel wire 25, thereby the steel wire 25 pulls the second sliding block 38 to move along the second sliding rail 19, the second sliding block 38 presses the self-resetting control button 17, the self-resetting control button 17 starts the alarm to make the alarm alarm to remind the staff. When the support pipe 24 is pushed out of the buffer column 5, the support pipe 24 drives the sliding block 31 to move upwards along the sliding rail 29 through the sleeve 26, the buffer rod 27 and the buffer cylinder 33, and at the same time, the buffer rod 27 is deeply inserted into the buffer cylinder 33 to compress the first spring 32, thereby playing a buffering role in the process of the electric wire 7 being straightened. When the electric wire 7 in the buffer column 5 is completely straightened, the electric wire 7 pushes the buffer column 5 to move through the first limiting block 10, the buffer column 5 is pressed to buffer through the support pipe 24, the sleeve 26 and the buffer rod 27. When the icing on the electric wire 7 is removed, the first spring 32 drives the support pipe 24 to move towards the buffer column 5 through the buffer rod 27 and the sleeve 26 to press the electric wire 7, so that the electric wire 7 in the buffer column 5 is bent again, thereby preparing for the next stress on the electric wire 7. Embodiment 2

[0036] As Figures 1-6As shown, in the case that other parts are same as those of example 1, the difference between the present example and example 1 is that the end of the electric wire 7 close to the electric pole 1 is wavy, the end of the electric wire 7 close to the electric pole 1 is sleeved with a sliding ring 12, the sliding ring 12 is fixedly connected with the front support 40 and the rear support 4 through a fixing rod 11, a third spring 13 is sleeved on the electric wire 7, one end of the third spring 13 is fixedly connected with the sliding ring 12, and the other end of the third spring 13 is fixedly connected with a fixing ring 14 which is fixedly sleeved on the electric wire 7.

[0037] Working principle: when the electric wire 7 in the buffer column 5 is completely straightened, since the end of the electric wire 7 close to the electric pole 1 is wavy, the wavy electric wire 7 is not forced before being straightened, so that the connecting end of the electric wire 7 and the electric pole 1 is not forced all the time, thereby effectively preventing the connecting end of the electric wire 7 and the electric pole 1 from being broken due to force.
