The labor intensity of personnel in the overlapping process is high, the operation is difficult, the efficiency is low, and the safety risk is high. The reasons for the above problems are mainly the long length and weight of the insulating operating rod, and the difficulty in operating the engaging operating mechanism. Especially in high-voltage lines with higher voltages, it is extremely difficult to operate the insulating operating rod that is more than 5 meters long to engage the grounding wire overlap joint with the conductor, and the safety risk is also high. Therefore, there is an urgent need to improve the existing high-voltage grounding wire to reduce its operating difficulty and further improve its safety and reliability of use.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the following description, in order to clearly show the structure and working mode of the present invention, the drawings will be used as a reference and described with the help of many directional terms, but the words "front", "back", "left", "right", "up", "down" and so on should be understood as convenient terms, and should not be understood as restrictive terms.

[0026] Figure 1-3The automatic gripping and tightening grounding wire clamp shown in the figure comprises a shell with a connecting portion at the upper end, an electric cylinder arranged in the shell with a screw rod facing downward, a battery arranged in the shell for powering the electric cylinder, a controller arranged in the shell for controlling the battery and the electric cylinder, a connecting rod hinged to a nut of the electric cylinder and extending downward, a lifting nut fixedly arranged at the lower end of the connecting rod, two Y-shaped force arms symmetrically located on both sides of the connecting rod and with upper ends hinged to the lower end of the shell respectively, two wire clamps symmetrically arranged on both sides of the lifting nut, and a wire clamp arranged at the lower end of the wire clamp and obliquely downward to the outside. The guide plate extends outward; the wire clamping member includes an intermediate force arm, and a wire clamp hinged at the lower end of the intermediate force arm and having a clamping groove on the inner side; the wire clamp is L-shaped, and the long side of the wire clamp is located at the upper part and tilted inward; the part of the intermediate force arm adjacent to the lifting nut is hinged to the side of the lifting nut; the upper part of the intermediate force arm is hinged to the lower end of the Y-shaped force arm on the side; when the electric cylinder drives the lifting nut to move downward, the lower parts of the two wire clamping members are separated to form an open state; when the electric cylinder drives the lifting nut to move upward, the lower parts of the two wire clamping members are close to form a clamping state.

[0027] When the two wire clamps are in the clamping state, the long side of the wire clamp flips upward along with the middle force arm. This split wire clamp can be replaced with different wire clamps according to the type of the clamped wire to improve applicability.

[0028] As a further improvement, it also includes a photoelectric switch arranged on the lifting nut for detecting the position of the long side of the wire clamp. The photoelectric switch is linked to the controller for control, and the position of the photoelectric switch can be adjusted according to the type of the clamped wire; when the wire is clamped in place, the long side of the wire clamp flips upward and is detected by the photoelectric switch. At this time, the controller controls the electric cylinder to stop, which can protect the wire and avoid clamping too tightly, and also protect the electric cylinder and battery, extending the service life of the electric cylinder and battery. The controller uses a controller with wireless transceiver function, which can be remotely controlled through a mobile device.

[0029] As a further improvement, a double-ear connecting seat connected to the Y-shaped force arm is provided at the lower end of the shell. The double-ear connecting seat can be connected to the shell by bonding or screwing, and obviously can also be made into an integral part with the shell by integral molding.
