[0002] At present, power supply reliability has become an important demand in social production and life, and the stability and rapid recovery of power supply quality are particularly important. However, in the process of traditional power generation vehicle access, old-style copper noses are usually used to fix medium and low voltage cables to the user end. This method has obvious shortcomings. First, the traditional connection method is time-consuming and usually requires a long wiring time. In addition, since parts such as copper noses require strong torque to be firmly connected, the labor intensity of operators is high and the efficiency is low. Secondly, the old-style copper nose has a complex structure, which increases the risk of contact with live parts during operation. Once a mistake occurs, it may cause electric shock accidents, which poses obvious safety hazards.

[0013] A method for using a medium and low voltage power generation vehicle quick access and exit operation auxiliary device, comprising the following steps:

[0014] Step 1. Check the status of each component: Before use, ensure that all components, namely the hand crank, connecting rod, thread locking parts, wire clamps, clamps and lifting eye screws are intact, check the condition of the anti-loosening nut and self-locking thread at the connection between the lifting eye screw and the wire clamp, and ensure that the anti-loosening device is intact to prevent loosening during operation. Prepare the insulating boom truck or the insulating operating rod required for the ground potential operation method according to the actual working environment;

[0015] Step 2. Install the hand crank and adjust the angle: Connect the hand crank to the quick access end of the generator car, ensure that the connection is firm, make the generator car and the device on the same axis, and rotate and adjust the direction angle of the hand crank to put the device in the best operating position;

[0016] Step 3. Fix the connecting rod and the wire clamp: connect one end of the hand crank with the connecting rod through a thread, connect the other end of the connecting rod with the thread locking piece, and make sure to tighten them to prevent loosening. Place a screw washer at the connection between the connecting rod and the thread locking piece to prevent the connecting rod and the thread locking piece from sliding during rotation and operation.

[0017] Step 4. Install the wire clamp and adjust the tightening method: Connect the wire clamp to the eye screw firmly, and ensure that the U-shaped groove direction of the wire clamp is suitable for the size and position of the wire, so that the wire clamp can quickly clamp the wire and facilitate the subsequent quick withdrawal operation;

[0018] Step 5. Fix the wire clamp on the wire: Use an insulation gun to align the U-shaped notch of the wire clamp with the wire, then hang the wire clamp on the wire, make sure the wire is firmly clamped in the U-shaped groove, and prepare to tighten further;

[0019] Step 6. Tighten the eye screw and anti-loosening device: Rotate the eye screw clockwise to fix the wire clamp on the wire. At this time, the eye of the eye screw serves as a handle to facilitate manual operation by the operator. Tighten the anti-loosening nut to prevent the eye screw from loosening during operation.

[0020] Step 7, clamping point angle adjustment: Use the hand crank to adjust the position of the wire clamp to achieve a more suitable operating angle. The operator applies his own weight to the device through the hand crank, and uses the lever effect to achieve a slight deflection of the clamping point to ensure the clamping effect and prepare for subsequent operations.

[0021] Step 8. Quickly exit the operation after the operation is completed: After the operation is completed, rotate the lifting ring screw counterclockwise to gradually loosen the wire clamp and release the wire. After confirming that the wire clamp is completely separated from the wire, remove the wire clamp from the wire. Finally, remove the connection between the hand crank and the access end of the generator car to complete the disassembly of the entire device.

[0022] Step 9, Maintenance and Storage: After the operation, check the status of the anti-loosening nut, self-locking thread and hand crank to ensure that there is no damage when it is used next time, clean all parts of the device, and store them properly in the tool box to prevent dust and damage.

[0023] Beneficial effects of the present invention:

[0024] 1. Efficient connection and quick exit: The medium and low voltage generator car quick access and exit operation auxiliary device of the present invention realizes the quick operation of generator car access and exit through the threaded hand crank, connecting rod and wire clamp structure, significantly shortens the wiring time, reduces the labor intensity of operators, and greatly improves the power supply operation efficiency;

[0025] 2. Stable structure, safe and reliable: The medium and low voltage power generation vehicle quick access and exit operation auxiliary device of the present invention uses anti-loosening nuts, self-locking threads and lifting eye screws for fixed connection, which ensures that the device is not easy to loosen during operation, avoiding the problem of unstable connection in traditional devices. The design of the threaded locking piece increases the connection strength, so that the device can still maintain reliability in a high-voltage environment, reducing the risk of electric shock and ensuring operation safety;

[0026] 3. Flexible adjustment and strong adaptability: The hand crank provides a universal adjustment function, which is convenient for operators to adjust the device angle according to needs and adapt to different working environments. Even when the operating space is limited or the wire position is special, the device can quickly adjust the angle to ensure the stability of clamping;

[0027] 4. Reduce labor intensity: The medium and low voltage generator vehicle quick access and exit operation auxiliary device of the present invention makes the device easy to operate through the design of U-shaped wire clamp and lifting eye screw rod. The U-shaped wire clamp facilitates the quick clamping and release of the wire, so that the operator can make a stable connection without applying too much effort. In addition, the lifting eye screw rod is used as a handle, which facilitates manual tightening and reduces the workload;

[0028] 5. Enhanced service life and easy maintenance: The auxiliary device for quick access and exit of medium and low voltage power generation vehicles of the present invention has a compact structure design. The configuration of screw washers and stop nuts reduces wear and loosening, thereby extending the service life of the device.
