Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
According to the characteristics of the electroscope and the grounding wire, the triangular clamp with the triangular opening is made of stainless steel materials by utilizing the characteristics of stability, firmness and pressure resistance of the triangle, and the insulating rod of the electroscope and the grounding wire is tightly fixed by using rubber clamping wheels and a cushion cover at three points of the triangular clamp, so that the insulating rod is guaranteed not to be damaged.
As shown in fig. 1 to 3, an electroscope and ground wire fixing device comprises two triangular clamps which are vertically symmetrical, wherein the triangular clamps are made of a stainless steel material with the thickness of 1-2mm by bending, the triangular clamps comprise a bottom plate 1 and clamping plates 2, the length of the bottom plate is 35-60mm, two sides of the bottom plate 1 are connected with the clamping plates 2 which are bent inwards, the clamping plates are bent upwards according to an angle of 95-115 degrees to form triangular clamps with triangular openings, the triangular clamps are elastic, and the openings can be changed when the triangular clamps are elastically deformed. Beat two 6 mm's aperture on the bottom plate, screw subassembly 5 passes the aperture, connects through screw subassembly 5 between two bottom plates 1, realizes the connection of two triangular clamp, and an insulating rod that the electroscope was used for cliping to a triangular clamp, and another triangular clamp is used for cliping the insulating rod of earth connection. The threaded component 5 is sleeved with a cushion cover 6, the clamping wheel 3 is arranged on the clamping plate 2, and the cushion cover and the clamping wheel form a triangular flexible clamping structure for clamping the insulating rod and avoiding damage to the insulating rod.
Specifically, bottom plate 1 includes sunken section 11 and holds in the palm section 12 outward, holds in the palm section 12 outward and is located sunken section 11's both ends to it is overhanging that outer support section 12 is sunken section 11 relatively, holds in the palm section 12 outward and is connected with end plate 21 arc through the arc changeover portion, connects through screw subassembly 5 between two sunken sections 11. The design of invagination section and outer support section for leave the clearance between the outer support section, change the fulcrum that the triangular clamp warp into the end of invagination section laminating department by the junction of bottom plate and splint, increased triangle-shaped elastic deformation's moment, make splint open easier, thereby optimize the elastic deformation of triangular clamp, use the operation more easily.
Specifically, splint 2 symmetry sets up in the both sides of bottom plate 1, and splint 2 is buckled equally and is formed, including end plate 21 and pterygoid lamina 22, pterygoid lamina 22 are located the both ends of end plate 21, and relative end plate 21 is inside to be buckled to end plate 21 and pterygoid lamina are perpendicular, and pinch roller 3 establishes between two pterygoid laminas 22, establishes between two pterygoid laminas 22 through round pin 4 activity. Preferably, press from both sides wheel 3 for rotatory plum blossom wheel, when the insulator spindle wants to break away from the triangular clamp because of gravity slope (the elasticity of splint is greater than gravity far away), the contact friction of insulator spindle drives the plum blossom wheel rotatory, and arc protruding can play on it can reduce the opening size of triangular clamp for the insulator spindle is difficult to drop from the triangular clamp. Meanwhile, when the protrusions are clamped tightly, the contact area between the protrusions and the insulating rod can be increased, and the stability of the insulating rod in the clamp is guaranteed.
Specifically, screw subassembly 5 is equipped with two sets ofly, and a aperture on a set of screw subassembly cooperation invagination board, screw subassembly 5 include screw rod and nut, and the screw rod passes two apertures of bottom plate 1 and is connected with the nut, compresses tightly two triangular clamp together, simple structure, easy dismounting. Meanwhile, the screw assembly is sleeved with the cushion cover, the blind hole is formed in the cushion cover, the blind hole is aligned with the screw assembly, and the screw assembly is sleeved without other means. The anti-slip lines on the screw component can increase friction with the cushion cover, and the anti-slip force of the cushion cover is improved.
The surface of the cushion cover 6 is provided with anti-skidding convex points which are used for contacting with the insulating rod, so that the stability of the insulating rod in the clamp is improved.
The using method comprises the following steps:
(1) and a yellow warning tape is pasted at the position of 0.4m between the electroscope electroscopic contact point and the insulating rod. The effect in warning area is electroscope electroscopic contact and earth clamp and keeps 0.4m safe distance (safety regulation requires that the worker work in normal home range and the safe distance of equipment strip point part, 10kV and above are 0.35m, and the safe distance in warning area is greater than the safety regulation specified value), guarantees not take place to articulate the ground wire with electricity when electroscopic.
(2) The use process comprises the following steps: and (5) stretching the electroscope to a working state to confirm that the electroscope is good. The triangular clamp of fixing device one end is blocked in electroscope's handle department, and the fastener of earth connection is no longer than electroscope's safe distance warning area, blocks the triangular clamp of the fixing device other end on the insulator spindle of earth connection, and the inspection electroscope contact point and the safe distance of the fastener of earth connection accord with the requirement after, begin to test the electricity. The three-phase four-wire electricity test is carried out respectively, after no electricity is confirmed, the ground wire is quickly connected, the functions of grounding and three-phase short circuit are achieved, the electroscope and the fixing device are taken down, and the whole work flow is finished.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
