Background
When the substation equipment is subjected to power failure maintenance, an operator often hangs the ground wire to equipment such as a lightning arrester and the like, and is difficult to effectively hang the ground wire to a lead of the equipment, because the equipment lead is often upright, if the ground wire is simply hung, poor contact between the ground wire and the lead or insufficient contact surface can not be effectively connected, even the ground wire falls off when the equipment lead shakes, the operating environment of the maintenance personnel under the closed ground wire is greatly discounted, and meanwhile, the occurrence of illegal behaviors caused by safety regulations is violated. The existing grounding device of the transformer substation is mainly realized by a grounding wire clamp, and the common clamping wire clamp for short-circuit grounding protection of the transformer substation is a spring clamp type wire clamp or a spiral compression type wire clamp.

Specifically, one end of the connecting member 102 located in the movable space 101a is provided with a first long groove 102a, the guide portion 103b is correspondingly provided with a second long groove 103b-1, two ends of the rotating shaft 101d are respectively provided with a rotating column 104a, and the rotating columns 104a at the two ends of the rotating shaft 101d are respectively embedded in the first long groove 102a and the second long groove 103 b-1. When the rotating member 104 rotates around the rotating shaft 101d, the rotating column 104a slides in the first elongated slot 102a and the second elongated slot 103b-1, and drives the guiding portion 103b and the connecting member 102 to move, and the directions of movement of the guiding portion 103b and the connecting member 102 are opposite.
Furthermore, one end of the pressing piece 103, which is located in the movable space 101a, further includes a limiting portion 103c, and the first elastic piece 105 is connected between the limiting portion 103c and one surface of the movable space 101 a; the first elastic member 105 is preferably a compression spring, and the tension of the first elastic member 105 keeps the distance between the pressing member 103 and the connecting member 102 to the maximum; the shell 101 is further provided with a first through hole 101e, a second elastic part 106 is arranged in the first through hole 101e, a first limiting pile 103a-1 is correspondingly arranged on the pressing part 103a, a second limiting pile 102b is correspondingly arranged at one end of the connecting part 102 positioned in the movable space 101a, and two ends of the first elastic part 105 are respectively connected with the first limiting pile 103a-1 and the second limiting pile 102 b; the second elastic member 106 is preferably a compression spring, and the tension of the second elastic member 106 maximizes the distance between the first position-limiting peg 103a-1 and the second position-limiting peg 102 b. That is, initially, under the action of the first elastic member 105 and the second elastic member 106, the movable clamping plate 202 tightly interferes with the fixed clamping plate 201.
Further, in order to prevent the pressing member 103 from tilting in the movable space 101a when the pressing member 103 is operated, the pressing member 103 further includes a guide post 103d, the guide post 103d is formed by extending both ends of the pressing member 103, the housing 101 is further provided with a second through hole 101f, and the guide post 103d is located in the second through hole 101f and moves in the axial direction of the second through hole 101f, so that the guide post 103d slides along the second through hole 101f without tilting when pressure is applied to the pressing member 103.
Further, the movable clamping plate 202 is provided with a leading-out terminal 202a, the leading-out terminal 202a is a conductor, a leading-out hole 102c is arranged at one end of the connecting piece 102 connected with the movable clamping plate 202, and the leading-out terminal 202a is connected with the leading-out hole 102 c. The ground wire is connected to the lead terminal 202a through the lead hole 102 c.

The working principle of the embodiment is as follows: in the initial state, the movable clamp plate 202 is against the fixed clamp plate 201, because the tension of the first elastic member 105 and the second elastic member 106 maximizes the distance between the first position-limiting pile 103a-1 and the second position-limiting pile 102b, i.e. the distance between the pressing portion 103a and the housing 101, when the lead of the vertical power transformation equipment needs to be grounded, the device is clamped on the vertical lead, specifically, the pressing portion 103a is pressed to slide toward the housing 101, the guiding portion 103b slides in the second sliding groove 101c, at this time, the distance between the limiting portion 103c and the movable space 101a becomes smaller, the first elastic member 105 contracts, the rotating column 104a of the rotating member 104 located in the second long groove 103b-1 moves along with the guiding portion 103b, so that the center of the rotating member 104 rotates around the rotating shaft 101d, the rotating column 104a of the rotating member 104 located in the first long slot 102a pushes the connecting member 102 to move, and the moving direction of the connecting member 102 is a direction close to the pressing portion 103a, at this time, the second elastic member 106 is compressed; because the connecting piece 102 is connected with the movable clamping plate 202, the movable clamping plate 202 moves along with the connecting piece 102, the movable clamping plate 202 is far away from the fixed clamping plate 201, at this time, a vertical lead wire to be grounded is placed in the first lead wire groove 202b and the second lead wire groove 201a, force is stopped to be applied to the pressing part 103a, the connecting piece 102 is reset under the reset tension action of the first elastic piece 105 and the second elastic piece 106, and the movable clamping plate 202 and the fixed clamping plate 201 clamp the vertical lead wire to complete clamping.
Example 3
Referring to fig. 1 to 6, a third embodiment of the present invention is based on the previous embodiment, and is different from the previous embodiment in that: in order to prevent the movable clamping plate 202 and the fixed clamping plate 201 from sliding on the vertical lead, the movable clamping plate 202 is further provided with a fastening groove 202c, the fastening groove 202c extends along the axis direction of the first lead groove 202b, namely the fastening groove 202c is arranged along the vertical lead, a fastening piece 203 is arranged in the fastening groove 202c, and the fastening piece 203 plays a role in extruding the vertical lead; the fastening slot 202c extends towards two sides to form an inclined slot 202d, the fastening piece 203 comprises a rolling shaft 203a and a rolling wheel 203b, the rolling shaft 203a is positioned in the inclined slot 202d, and the rolling wheel 203b is positioned in the fastening slot 202 c; specifically, the inclined groove 202d includes a first end 202d-1 and a second end 202d-2, the distance between the first end 202d-1 and the fixed clamp plate 201 is greater than the distance between the second end 202d-2 and the fixed clamp plate 201, when the inclined groove is installed, the first end 202d-1 is located below the second end 202d-2, and preferably, the surface of the rolling wheel 203b is provided with an anti-slip layer 203 b-1.
The working principle of the embodiment is as follows: the vertical leads to be grounded are placed in the first lead groove 202b and the second lead groove 201a, and the pressing part 103a is stopped from exerting force, so that the connecting part 102 is reset under the reset tension action of the first elastic part 105 and the second elastic part 106, and the movable clamping plate 202 and the fixed clamping plate 201 clamp the vertical leads to finish the clamping action. However, in some cases, the device may slide down along the vertical lead, so when the device tends to slide down, because the rolling wheel 203b always abuts against the vertical lead, when the movable clamp 202 slides down, the rolling wheel 203b does not move and the rolling shaft 203a slides along the inclined groove 202d, because the first end 202d-1 is located below the device, the rolling wheel 203b is carried by the opposite rolling shaft 203a to move along the first end 202d-1 to the second end 202d-2, and the upper end of the inclined groove 202d is offset towards the vertical lead, so that the pressing force of the rolling wheel 203b on the vertical lead is increased, the friction force is increased, and the device stops sliding down and tightly clamps the vertical lead.
