Description

Technical Field

[0001] The invention relates to the technical field of overhead insulated conductor grounding, in particular to a special needle puncture grounding device for overhead insulated conductors. Background Art

[0002] The so-called overhead line is relative to the cable, which is a line that transmits electric energy by erecting the conductor at a certain height by a tower. The insulation of the overhead line of the high-voltage transmission and distribution network to the ground is generally based on air. The previous distribution lines (below 10kV except 380V) generally used bare conductors. However, due to the complex power distribution environment in urban areas, short circuits and lightning strikes often occur, resulting in reduced power supply reliability. Therefore, currently, overhead lines below 10kV generally use insulated conductors (that is, the outer layer of the conductor is wrapped with an insulating layer). This is the so-called insulated overhead line. The special needle grounding device for overhead insulated conductors can ground the overhead insulated conductors, making the overhead insulated conductors safe during use.

[0004] According to the patent number CN202010221211.3 grounding device accessories and grounding device, the present application relates to a grounding device accessory and a grounding device, wherein the grounding device accessory is used to ground the capacitive voltage transformer against the conductor outside the line. The grounding device accessory includes a sleeve rod, a fixing device and a horizontal rod. The sleeve rod is sleeved on the conductor. The fixing device is mechanically connected to the sleeve rod. The fixing device is used to fix the sleeve rod to the conductor. The horizontal rod is fixedly connected to the sleeve rod. When in use, the horizontal rod is connected to the grounding assembly. The grounding device accessory provided in the embodiment of the present application uses the sleeve rod and the horizontal rod to achieve grounding of the conductor, which can ensure compliance with the power safety work regulations during maintenance, thereby avoiding safety hazards during maintenance work.

[0005] However, the existing needle-piercing grounding device for overhead insulated conductors and the above-mentioned device have the following shortcomings during use, such as:

[0006] During the use of the existing needle-piercing grounding device dedicated to overhead insulated conductors, the shaking of the overhead insulated wire will cause the grounding wire to shake. Since the grounding device is fixed to the ground, the grounding wire is broken. In addition, the use angle of the existing grounding device cannot be quickly adjusted and controlled as needed during use, making it inconvenient to adjust and change the use angle of the grounding device after it is buried in the ground, and it is not safe during use.

[0047] The method for using the special needle grounding device for overhead insulated conductors comprises the following steps:

[0048] S1: First, the wire body to be grounded is inserted through the conveying groove 32 and wound on the winding baffle plate 27. After the wire body is wound through the winding baffle plate 27 for several turns, the end is wound with the winding connection end 15 at the corresponding position to achieve wiring;

[0049] S2: Fixed burial can be achieved through the fixing plate 3 and the buried grounding frame 4, so that the wire connected to the winding connection terminal 15 is grounded through the sliding terminal 13 and the buried grounding frame 4;

[0050] S3: The driving gear 8 is driven to rotate by starting the motor 9, and the rotating driving gear 8 can drive the adjusting gear 7 to rotate, so that the angle adjustment and control of the buffer adjustment device 5 and the grounding device 6 as a whole can be achieved;

[0051] S4: The first sealing protection device 1 and the second sealing protection device 2 can be used to slide and close to protect the wiring, and the unused conveying groove 32 can be sealed by sliding the sealing sliding plate 38 into the conveying groove 32 to block the conveying groove 32.

[0052] When implementing this embodiment, the wire body that needs to be grounded is first inserted through the conveying groove 32 and wound on the winding baffle plate 27. After the wire body is wound around the winding baffle plate 27 for several turns, the end is wound around the winding connection terminal 15 at the corresponding position to achieve wiring. Fixed burial can be achieved through the fixed plate 3 and the buried grounding frame 4, so that the wire connected to the winding connection terminal 15 is grounded through the sliding terminal 13 and the buried grounding frame 4. The driving gear 8 is driven to rotate by the starting motor 9. The rotating driving gear 8 can drive the adjusting gear 7 to rotate, thereby realizing the angle adjustment and control of the overall use of the buffer adjustment device 5 and the grounding device 6. The sliding closure of the first sealing protection device 1 and the second sealing protection device 2 can protect the wiring. Example 2

[0053] On the basis of Example 1, Figure 9-10 As shown, rotating rollers 37 are rotatably installed inside the two sides of the conveying groove 32, and a sealing sliding plate 38 is evenly slidably inserted on one side of the limiting frame 33.

[0054] When this embodiment is implemented, the rotating roller 37 rotates inside the conveying trough 32, so that the line passing through the conveying trough 32 can be pulled and adjusted conveniently, thereby reducing the friction between the line and the conveying trough 32, and the sealing sliding plate 38 slides into the conveying trough 32 to seal the conveying trough 32, so that the unused conveying trough 32 can be sealed, so that during outdoor use, rainwater can easily enter the device from the conveying trough 32 in large quantities, making the device safe during use.

[0055] Working principle: The device is buried in the ground through the fixed plate 3 and the buried grounding frame 4 for use. First, the wire body to be grounded is inserted through the conveying groove 32 and wound on the winding baffle plate 27. After the wire body is wound through the winding baffle plate 27 for several turns, the end is wound with the winding connection end 15 at the corresponding position to achieve wiring. The fixed burial can be achieved through the fixed plate 3 and the buried grounding frame 4, so that the wire connected to the winding connection end 15 is grounded through the sliding terminal 13 and the buried grounding frame 4. The driving gear 8 is driven to rotate by the starting motor 9, and the rotating driving gear 8 can drive the adjustment The gear 7 rotates, so that the angle adjustment and control of the use of the buffer adjustment device 5 and the grounding device 6 as a whole can be achieved. The sliding and closing of the first sealing protection device 1 and the second sealing protection device 2 can protect the wiring. The rotating roller 37 rotates inside the conveying groove 32, which makes it easy to pull and adjust the wire body passing through the conveying groove 32, reducing the friction between the wire body and the conveying groove 32. The sealing sliding plate 38 slides into the conveying groove 32 to block the conveying groove 32, so that the unused conveying groove 32 can be sealed, so that it can be used outdoors. In order to facilitate rainwater to enter the device in large quantities from the conveying trough 32, the device is safe during use. When the connected wire is shaken by external force, the wire body wound on the winding baffle plate 27 rotates, so that the wire body wound on the winding baffle plate 27 extends and is wound by the return spring 28, thereby realizing the automatic winding and unloading force, so that the wire body connected to the winding connection end 15 will not break, and the rotating adjustment disk 22 is rotated by external force. At this time, the rotating adjustment disk 22 is threadedly rotated on the threaded column 23, so that the rotating rotating adjustment disk 22 passes through the arc extrusion groove 24. The sliding baffle column 25 can be squeezed outward so that the sliding baffle column 25 extending outward can block the wire body wound on the winding baffle plate 27 to prevent the wire body from being separated from the winding baffle plate 27. The first sealing protection device 1 and the second sealing protection device 2 are made to be spliced ​​by sliding the protective cover 31 in the first sealing protection device 1 and the second sealing protection device 2. The upper part of the device can be covered by the protective cover 31, thereby playing a good protective role during the use of the device. The device can be conveniently grounded during use, and the wiring is safe and will not break during use.
