DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 5 As shown, a high-voltage transmission line broken fast cable retracting device comprises an insulating frame 1, a cable retracting structure 2 and a current transformer 3. A mounting frame 14 is fixed above the insulating frame 1. The mounting frame 14 is used to connect the entire device to the high-voltage line tower. A cable connection block 12 is connected to one side of the insulating frame 1 close to the mounting frame 14. Terminal blocks 13 are connected to both sides of the cable connection block 12. Two groups of cable retracting structures 2 are provided and are respectively arranged at both ends of the insulating frame 1 for retracting the transmission line. Two current transformers 3 are provided and are respectively arranged between the corresponding terminal blocks 13 and the cable retracting structure 2. The transmission line can slide through the loop of the current transformer 3. The current transformer 3 can sense the current value of the high-voltage cable passing through itself. Whether the transmission line is broken is judged from the current measured by the current transformer 3. The device also comprises a traction component 4 and a storage basket 5.

[0028] There are two groups of traction components 4, which are respectively arranged between the corresponding current transformers 3 and the wiring terminals 13, and the traction components 4 cooperate with the cable receiving structure 2;

[0029] Connecting rods 51 are fixed to both sides of the storage basket 5 , and the storage basket 5 is connected to the insulating frame 1 via the connecting rods 51 . A reciprocating motion structure is provided between the two connecting rods 51 , and a guide ring 56 is provided in cooperation with the reciprocating motion structure.

[0030] In some specific embodiments, such as Figure 2As shown, in order to facilitate the collection of cables, each set of cable collection structure 2 includes a support wheel 21, a vertical plate 22, a driving wheel 23 and a motor 24. The support wheel 21 is rotatably set on the insulating frame 1, and the pressure detection mechanism is connected to the support wheel 21. Two vertical plates 22 are provided, both of which are fixedly arranged on the insulating frame 1 in parallel. The two ends of the driving wheel 23 are respectively rotatably connected to the corresponding vertical plates 22, and the driving wheel 23 and the support wheel 21 cooperate to clamp the wires. The motor 24 is fixed on one side of the vertical plate 22, and the output end of the motor 24 is coaxially connected to the driving wheel 23. The pressure detection mechanism is used to detect whether there is a power transmission line at the upper end of the support wheel 21.

[0031] After one end of the high-voltage transmission line is connected to the terminal 13, it passes upward from the lower end of the guide ring 56, then passes between the driving wheel 42 and the driven wheel 43, passes through the current transformer 3, and finally passes out from between the support wheel 21 and the driving wheel 23. The other end of the high-voltage transmission line is connected to the terminal 13 on another high-voltage line tower in a symmetrical manner.

[0032] In some specific embodiments, such as Figure 3 As shown, in order to prevent the collected power transmission lines from piling up between the cable receiving structure 2 and the terminal block 13, each traction assembly 4 includes a through hole 41, a driving wheel 42, and a driven wheel 43. The through hole 41 is vertically opened on the insulating frame 1. The driving wheel 42 and the driven wheel 43 are both rotatably connected in the through hole 41. The driving wheel 42 and the driven wheel 43 cooperate to clamp the wires. The rotation of the driving wheel 42 can drive the power transmission line to retract. A synchronous belt 44 is cooperated between the driving wheel 42 and the driving wheel 23.

[0033] When it is determined that the high-voltage transmission line is disconnected, the motor 24 is started, and the output shaft of the motor 24 rotates to drive the driving wheel 23 to rotate. The rotation of the driving wheel 23 can drive the transmission line in contact with it to retract toward the corresponding terminal 13. At the same time, the rotation of the driving wheel 23 can drive the driving wheel 42 to rotate, so that the retracted transmission line is pulled downward by the driving wheel 42 and the driven wheel 43, and finally the transmission line passes through the guide ring 56 and falls into the storage basket 5. When the pressure detection mechanism detects that the gravity of the transmission line disappears, the transmission line that falls on the ground is lifted up by the cable-retracting structure 2 and is off the ground to a safe distance, and then the motor 24 is stopped.

[0034] In some specific embodiments, such as Figure 3As shown, in order to facilitate the placement of more cables in the storage basket 5, the reciprocating motion structure includes a reciprocating screw 52, ​​a second motor 54 and a limit rod 53. The second motor 54 is fixed on the connecting rod 51, and the second motor 54 is electrically connected to the current transformer 3. One end of the reciprocating screw 52 passes through the corresponding connecting rod 51 and is coaxially connected to the output end of the second motor 54. A moving block 55 is threadedly connected to the outer side of the reciprocating screw 52. The limit rod 53 passes through the moving block 55 and is connected between the two connecting rods 51. The moving block 55 can slide along the limit rod 53, and the guide ring 56 is connected to the moving block 55.

[0035] After the transmission line break is detected, the motor 2 54 is started to drive the reciprocating screw 52 to rotate, and the moving block 55 slides back and forth along the limit rod 53, so that the guide ring 56 pulls the transmission line back and forth, so that the transmission line is folded back and forth and neatly distributed in the storage basket 5, so that the transmission line is evenly placed in the storage basket 5, thereby increasing the space utilization rate of the storage basket 5 and avoiding the transmission line that needs to be retracted to be too long, causing the transmission line to overflow and fall.

[0036] In some specific embodiments, such as Figure 3 As shown, in order to facilitate the high-voltage transmission line to fall smoothly into the storage basket 5, the guide ring 56 is horizontally connected to one side of the moving block 55.

[0037] In some specific embodiments, in order to prevent the corners of the guide ring 56 from scratching the high-voltage transmission line, Figure 4 As shown, a guide post 57 is provided on one side of the guide ring 56 close to the wiring terminal 13 , and the guide post 57 is rotatably connected to the guide ring 56 .

[0038] In some specific embodiments, such as Figure 5 As shown, in order to facilitate the detection of whether there are wires on the support wheel 21, the pressure detection mechanism includes a pressure rod 61, a slot 63 and a spring 65. Two pressure rods 61 are provided, and are coaxially rotatably connected to the two ends of the support wheel 21 respectively. Strip sliding holes 62 are opened on both sides of the insulating frame 1. The pressure rod 61 passes through the strip sliding hole 62. The lower end of the pressure rod 61 is vertically connected with an insertion rod 64. The slot 63 is opened at the lower end of the strip sliding hole 62. The insertion rod 64 is plugged into the slot 63. The spring 65 is sleeved on the outside of the insertion rod 64. A bearing plate 66 is provided on one side of the insulating frame 1. A pressure sensor 67 is fixed on the top of the bearing plate 66. The pressure sensor 67 cooperates with the pressure rod 61. The pressure sensor 67 is electrically connected to the motor 1 24 and the motor 2 54.

[0039] When there is a power transmission line on the support wheel 21, the pressure rod 61 drives the insertion rod 64 to move downward, the spring 65 is compressed, and the pressure rod 61 transmits the gravity of the power transmission line to the pressure sensor 67. When there is no power transmission line passing through the support wheel 21, the rebound force of the spring 65 resets the pressure rod 61. After the pressure sensor 67 can no longer sense the pressure of the power transmission line, it transmits a signal to the motor 1 24 and the motor 2 54 to stop working.

[0040] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0041] When the current transformer 3 cannot sense that there is current passing through the high-voltage transmission line, it means that the high-voltage transmission line has been disconnected. When it is determined that the high-voltage transmission line is disconnected, the motor 24 is started, and the output shaft of the motor 24 rotates to drive the driving wheel 23 to rotate. The rotation of the driving wheel 23 can drive the transmission line in contact with it to shrink toward the corresponding terminal 13. Finally, the transmission line passes through the guide ring 56 and falls into the storage basket 5. While starting the motor 24, the motor 2 is started, and the reciprocating screw 52 is driven to rotate. The moving block 55 slides back and forth along the limit rod 53, so that the guide ring 56 pulls the transmission line back and forth, so that the transmission line is folded back and forth and neatly distributed in the storage basket 5, so that the transmission line is evenly placed in the storage basket 5, increasing the space utilization rate of the storage basket 5, and avoiding the transmission line that needs to be retracted to be too long, causing the transmission line to overflow and fall. When the pressure sensor 67 detects that the gravity of the transmission line disappears, the transmission line that falls on the ground is lifted up by the cable-retracting structure 2 and is off the ground to a safe distance, and the motor 24 and the motor 2 are stopped.

[0042] At the same time, by setting a synchronous belt 44, the rotation of the driving wheel 23 can also drive the driving wheel 42 to rotate, so that the retracted transmission line is pulled downward by the driving wheel 42 and the driven wheel 43, avoiding the retracted transmission line from accumulating between the terminal 13 and the cable receiving structure 2.

[0043] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
