Description

Technical Field

[0001] The utility model relates to the technical field of grounding wire clamps, in particular to an intelligent wire clamp. Background Art

[0002] High-voltage grounding wire is an auxiliary electrical safety device for power maintenance. Its purpose is to prevent electrostatic induction and electric shock or accidental closing of the switch from nearby charged bodies. It generally includes wire clamps, short-circuit lines, grounding wires, grounding rods, busbar clamps, and grounding clamps. Currently, most existing wire clamps are tongue-type clamping type. When installing and removing, workers need to pull down or lift up the insulating rod to press the wire of the power outage maintenance equipment into or out of the wire clamp. Whether the clamping force of the wire clamp on the cable is stable is determined by the workers' feelings. There is no intuitive feedback on whether the wire clamp is clamping the cable. Therefore, it is still possible that the cable is not clamped, resulting in failure of the conductive connection and causing risks. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 4 As shown, in an embodiment of the utility model, an intelligent wire clamp is proposed, including a holding rod 1 and a connecting member 2 installed on the holding rod 1, a main wire clamp 3 and a wire clamp cable 4 which can slide relative to the main wire clamp 3 are installed on the connecting member 2, a driving mechanism 5 for driving the wire clamp cable 4 to slide up and down is provided on the connecting member 2, the main wire clamp 3 and the wire clamp cable 4 are enclosed to form a clamping cavity 6 with an adjustable inner diameter, after the entire intelligent wire clamp is moved to the position where the cable needs to be clamped by the holding rod 1, the main wire clamp 3 is pre-set on the cable, and then the driving mechanism 5 is controlled to operate to make the wire clamp cable 4 slide relative to the main wire clamp 3, and the size of the clamping cavity 6 is adjusted until the cable is clamped.

[0026] Further intuitive feedback is required on whether the cable is clamped, so as to control the specific action of the driving mechanism 5. Specifically, it also includes a micro pressure sensor 7. The micro pressure sensor 7 is arranged on the top surface of the main wire clamp 3 in the clamping cavity 6, or the micro pressure sensor 7 is arranged at the position where the driving mechanism 5 and the wire clamp cable 4 abut. The micro pressure sensor 7 is used to detect the pressure applied to the cable after being clamped by the clamping cavity 6, or the pressure applied to the wire clamp cable 4 by the driving mechanism 5 is directly detected to form the pressure applied to the cable in the clamped state. Based on the feedback pressure, the specific state of the cable clamping can be intuitively fed back.

[0027] At the same time, it also includes a handheld controller 8, which is electrically connected to the micro pressure sensor 7 and the driving mechanism 5. The handheld controller 8 is integrated with a display screen and a control circuit. The pressure feedback from the micro pressure sensor 7 is intuitively displayed on the display screen. The operator can control the action of the driving mechanism 5 through the handheld controller 8 based on the feedback pressure, so that it can be more clear whether the clamping state of the cable is stable.

[0028] The handheld controller 8, the driving mechanism 5 and the micro pressure sensor 7 all adopt relatively mature technologies, and after integration, they can more intelligently and intuitively realize the size adjustment process of the clamping cavity 6 and the pressure feedback after the cable is clamped. The operator can more clearly understand the clamping state to determine the current clamping situation of the cable.

[0029] The driving mechanism 5 can be implemented in a variety of ways, specifically to drive the movement of the wire clamp cable 4. In one embodiment, the driving mechanism 5 includes a stepper motor 9 and a rotating sleeve 10 connected to the output shaft of the stepper motor 9, and a push rod 11 is threadedly connected to the rotating sleeve 10, and the push rod 11 is rotatably connected to the wire clamp cable 4; after the stepper motor 9 rotates the rotating sleeve 10, the push rod 11 is threadedly rotated relative to the rotating sleeve 10, and because the upper end of the push rod 11 is connected to the wire clamp cable 4, when the wire clamp cable 4 is limited to slide relative to the main wire clamp 3, the thread rotation is converted into a lifting action of the push rod 11, so as to drive the wire clamp cable 4 to slide up and down, specifically, the stepper motor 9 can be controlled to rotate forward and reverse.

[0030] Specifically, in this embodiment, the connecting member 2 includes a mounting shell 15, the stepping motor 9 is installed in the mounting shell 15, a first connecting seat 16 is installed on the mounting shell 15, and a second connecting seat 17 is installed on the holding rod 1. The first connecting seat 16 and the second connecting seat 17 are connected via a plum blossom joint 18. After the first connecting seat 16 and the second connecting seat 17 are connected via the plum blossom joint 18, the entire mounting shell 15 can be adjusted in angle relative to the holding rod 1 and the adjusted angle can be locked, so as to facilitate angle adjustment according to the cable direction and the operator's position before sheathing the cable.

[0031] Meanwhile, a power supply control box 19 is installed on the installation shell 15 , and a power supply module is integrated in the power supply control box 19 . The power supply module is used to control the power supply of the stepping motor 9 , thereby realizing forward and reverse rotation control.

[0032] In another embodiment, the driving mechanism 5 includes a push rod motor 12 and a push rod 11 slidably mounted on the connecting member 2, the upper end of the push rod 11 is fixed on the wire clamp cable 4, the push rod of the push rod motor 12 is in contact with the push rod 11, and the micro pressure sensor 7 is installed at one end of the push rod 11 close to the push rod motor 12. The push rod motor 12 directly applies a pushing force to the push rod 11 to push the wire clamp cable 4 to slide, and the size adjustment of the clamping cavity 6 can also be achieved.

[0033] In this embodiment, the connecting member 2 includes a cylindrical connecting seat 20 which is sleeved on the holding rod 1, and the push rod motor 12 is installed in the cylindrical connecting seat 20, wherein the push rod 11 is slidably installed on the cylindrical connecting seat 20, and the push rod motor 12 is installed in the cylindrical connecting seat 20, thereby enabling the relative moving axis of the push rod of the push rod motor 12 and the sliding axis of the push rod 11 to be coaxially pushed.

[0034] Therefore, the driving mechanism 5 in the above two embodiments can be used to adjust the size of the clamping cavity 6 and can be controlled by the handheld controller 8.

[0035] Specifically, it also includes a grounding clamp 13, which is installed on the main line clamp 3. The grounding clamp 13 is used to connect the grounding wire, and the grounding clamp 13 maintains a stable conductive connection with the main line clamp 3 to ensure that the cable maintains a stable conductive connection with the grounding wire after being clamped.

[0036] Specifically, the gripping rod 1 is made of insulating material, and a rubber grip 14 is sleeved on the end of the gripping rod 1. The insulation of the gripping rod 1 improves the safety of the operator. The rubber grip 14 is sleeved on the end to further ensure insulation and also prevent slipping when gripping.
