[0002] In the production process of power grids, "grounding wire" is the most important, reliable and effective safety measure to prevent calls from all directions within the working range and protect the lives of workers. Usually, when inspecting power grid lines or substations, it is necessary to use grounding wire adapter tools to connect grounding wires and grounding conductors, and connect grounding wires and equipment conductors or cables to ensure the safety of maintenance workers.

[0003] The grounding wire adapter tool includes a pair of pliers for connecting the equipment conductor or cable and a grounding clamp for connecting the grounding conductor. The existing grounding clamp is provided with a clamping opening that can be tightened and loosened, and after fixing one end of the grounding wire, the grounding clamp can be tightened by rotating the screw of the grounding clamp, thereby clamping the grounding clamp on the grounding conductor.

[0004] In actual operation, since the grounding clamp is pulled by the grounding wire, it is easy for it to be loosely clamped or even fall off the grounding conductor, which may cause the equipment to reverse power and make the equipment within the working range energized, seriously endangering the lives of the work team members within the working range.

[0042] Typically, the middle portion of the clamping screw 30 passes through a side wall of the clamping opening 11 , and a rotating handle 31 is provided at one end of the clamping screw 30 away from the clamping block 20 to facilitate driving the clamping screw 30 to rotate and provide sufficient rotational driving force.

[0043] Combination Figure 2 and Figure 3The pressurizing mechanism 40 includes: a pressurizing cylinder 41, which is arranged in the clamping opening 11, and the pressurizing cylinder 41 extends in the direction of the clamping opening 11, and one end of the pressurizing cylinder 41 away from the clamping block 20 is sealed and fixedly connected to the clamping body 10, and the other end of the pressurizing cylinder 41 is sealed; a pressurizing piston 42, which is arranged in the pressurizing cylinder 41, and the pressurizing piston 42 is adapted to the inner cavity of the pressurizing cylinder 41, and the pressurizing piston 42 can move along the axial direction of the pressurizing cylinder 41; a pressurizing transmission rod 43, one end of the pressurizing transmission rod 43 is connected to the pressurizing piston 42, and the pressurizing transmission rod The middle seal of 43 is movably arranged in one end of the pressurizing piston 42 facing the clamping block 20, and the other end of the pressurizing transmission rod 43 is detachably connected to the clamping block 20; an energy storage cylinder 44, wherein the energy storage cylinder 44 is adapted with an elastic energy storage component 45, and the oil inlet end of the energy storage cylinder 44 is connected with the oil outlet end of the pressurizing cylinder 41; an energy storage piston 46, wherein the energy storage piston 46 is arranged in the energy storage cylinder, the energy storage piston 46 is adapted with the inner cavity of the energy storage cylinder 44, and the energy storage piston 46 can move along the axial direction of the energy storage cylinder 44; wherein, in the working state, the cavity between the pressurizing piston 42 and the pressurizing cylinder 41 stores insulating oil.

[0044] Thus, when clamping is required, the pressure transmission rod 43 is connected to the clamping block 20, so that when the clamping screw 30 rotates, the pressure transmission rod 43 moves with the clamping block 20 to drive the pressure piston 42 to move toward the clamping block 20, thereby pressing the insulating oil in the pressure cylinder 41 into the energy storage cylinder 44, and pushing the energy storage piston 46 to move, and then driving the elastic energy storage member 45 to store energy, so that the insulating oil has sufficient pressure. To ensure that the pressure mechanism 40 stores energy while the clamping screw 30 rotates, and to ensure that the pressure mechanism 40 can drive the locking mechanism 50 to lock the clamping screw 30 after being connected to the locking mechanism 50. When the clamping screw 30 needs to be unlocked, the connection between the pressure transmission rod 43 and the clamping block 20 is disconnected. At this time, the elastic energy storage member 45 drives the energy storage piston 46 to reset, so that the pressure mechanism 40 and the locking mechanism 50 can be reset.

[0045] In this embodiment, the pressurization transmission rod 43 can rotate along its own axis relative to the pressurization cylinder 41, and the pressurization transmission rod 43 is screwed to the clamping block 20, so as to facilitate connecting the pressurization transmission rod 43 and the clamping block 20 while facilitating disconnecting the connection between the pressurization transmission rod 43 and the clamping block 20.

[0046] Specifically, the material of the pressurizing transmission rod 43 is polytetrafluoroethylene, so as to utilize the self-lubricating property of polytetrafluoroethylene to reduce the resistance of the pressurizing transmission rod 43 to rotation and movement, and at the same time, to reduce the damage to the corresponding sealing parts when the pressurizing transmission rod 43 is in motion. At the same time, the elastic energy storage member 45 is a compression spring, and one end of the elastic energy storage member 45 abuts against the energy storage piston 46, and the other end of the elastic energy storage member 45 abuts against the corresponding end of the energy storage cylinder 44.

[0047] It can be understood that the energy storage cylinder 44 is integrally provided with the clamp body 10 to simplify the structure of the device.

[0048] Combination Figure 3 The locking mechanism 50 includes: a locking cylinder 52, the oil inlet end of the locking cylinder 52 is connected to the oil outlet end of the energy storage cylinder 44, and the locking operating rod 51 can control the on-off connection between the oil inlet end of the locking cylinder 52 and the oil outlet end of the energy storage cylinder 44; a locking piston 53, the locking piston 53 is arranged in the locking cylinder, the locking piston 53 is adapted to the inner cavity of the locking cylinder 52, and the locking piston can move axially along the locking cylinder 52; a locking rod 54, the locking rod 54 is movably arranged in the clamp body 10, one end of the locking rod 54 is connected to the locking piston 53, the middle seal of the locking rod 54 is movably penetrated in one end of the locking piston 53 facing the clamping screw 30, and the other end of the locking rod 54 is arranged facing the rod portion of the clamping screw 30. Thus, the locking operating rod 51 is pulled, so that the liquid outlet end of the energy storage cylinder 44 of the pressurizing mechanism 40 is connected to the oil inlet end of the locking cylinder 52, so that the insulating oil with corresponding pressure enters the locking cylinder 52 and pushes the locking piston 53 to move toward the clamping screw 30, thereby making the end of the locking rod 54 tightly pressed on the clamping screw 30, thereby achieving the purpose of locking the clamping screw 30.

[0049] It should be noted that a connecting flow channel 13 is provided in the clamp body 10, and the connecting flow channel 13 can connect the oil inlet end of the locking cylinder 52 with the oil outlet end of the energy storage cylinder 44; the locking operating rod 51 is movably inserted on the clamp body 10, and a flow hole is provided in the middle part of the locking operating rod 51. By moving the locking operating rod 51, the flow hole can be connected to the connecting flow channel 13 to ensure that the locking operating rod 51 can control the pressurizing mechanism 40 to drive the locking mechanism 50 to open and close the insulating oil.

[0050] In summary, the multifunctional grounding wire adapter provided in this embodiment includes a clamping body 10, a clamping block 20, a clamping screw 30, a pressurizing mechanism 40 and a locking mechanism 50. A clamping opening 11 is provided on one side of the clamping body 10. The clamping block 20 is slidingly connected to the clamping body 10. The clamping screw 30 is screwed to a side wall of the clamping opening 11. The clamping screw 30 is rotatably connected to the clamping block 20. The pressurizing mechanism 40 is provided on the clamping body 10, and the pressurizing mechanism 40 is linked to the clamping screw 30.

[0051] When in use, the clamping screw 30 is rotated so that the opening between the clamping block 20 and the side wall of the clamping opening 11 can be sleeved outside the grounding conductor, and then the clamping body 10 is sleeved outside the corresponding grounding conductor. The pressurizing transmission rod 43 is connected to the clamping block 20, and the clamping screw 30 is rotated again so that the clamping block 20 moves toward the other side wall of the clamping opening 11, thereby clamping the grounding conductor in the clamping opening 11. While the clamping screw 30 is rotating, the pressurizing transmission rod 43 moves with the clamping block 20 to drive the pressurizing piston 42 to move toward the clamping block 20, thereby pressing the insulating oil in the pressurizing cylinder 41 into the energy storage cylinder 44, and pushing the energy storage piston 46 to move, and then driving the elastic energy storage member 45 to store energy, so that the insulating oil has sufficient pressure.

[0052] When the clamping screw 30 cannot continue to rotate, the clamping block 20 and the side wall of the clamping opening 11 have clamped the grounding conductor. At this time, the locking operating rod 51 is pulled to connect the flow hole to the connecting channel 13, so that the pressurizing mechanism 40 and the locking mechanism 50 are connected. That is, at this time, the liquid outlet end of the energy storage cylinder 44 of the pressurizing mechanism 40 is connected to the oil inlet end of the locking cylinder 52, so that the insulating oil with corresponding pressure enters the locking cylinder 52, and pushes the locking piston 53 to move toward the clamping screw 30, so that the end of the locking rod 54 is pressed tightly against the clamping screw 30, so as to achieve the purpose of locking the clamping screw 30. Among them, because the locking operating rod 51 can maintain a working state under the action of hydraulic pressure, so that the energy storage cylinder 44 and the locking cylinder 52 remain connected.

[0053] When it is necessary to remove the clamp body 10 from the grounding conductor, the pressurizing transmission rod 43 is rotated to disconnect the connection between the pressurizing transmission rod 43 and the clamping block 20. At this time, under the resetting action of the elastic energy storage member 45, the energy storage piston 46 is driven to reset, so that the insulating oil in the energy storage cylinder 44 flows back into the pressurizing cylinder 41, and drives the pressurizing piston 42 to reset, so that the pressurizing mechanism 40 is reset, and the hydraulic pressure of the energy storage cylinder 44 returns to normal pressure. At this time, the pressure of the locking rod 54 on the clamping screw 30 is reduced, and the clamping screw 30 can be rotated. By rotating the clamping screw 30, the clamping block 20 is driven to reset, and the clamp body 10 can be removed.

[0054] In summary, the multifunctional grounding wire adapter provided in this embodiment can lock the clamping block 20 after the clamping screw 30 drives the clamping block 20 to clamp the grounding conductor, so as to ensure that the grounding clamp can be stably clamped on the grounding conductor, thereby preventing the grounding clamp from loosening and falling off, and then ensuring the life safety of the operating personnel.
