Specific embodiment
Earth resistance of power transmission line measures special complete tool, as shown in Figure 1, including the first wire-wrap board 1, the second wire-wrap board 2 and two L-shaped grounding rods 33, a ring survey line 3, each ring survey line are wound respectively on the first wire-wrap board 1 and the second wire-wrap board 2 Connecting line 32 is set between 3 and corresponding grounding rod 33, several lantern rings 30,32 both ends of connecting line point are set on each ring survey line 3 Not She Zhi a collet 31, ring survey line 3 connect by lantern ring 30 with collet 31, and lantern ring 30 is arranged in this structure on ring survey line 3, Convenient for connecting with connecting line, lantern ring 30 is the aluminum casing that 3 outer layer of ring survey line installs additional, frequent use without injuring inner lead, It can be avoided the stranded phenomenon of interior metal after frequently being clamped by collet 31 of ring survey line 3, easy to use and flexible can be according to not Same tower, any to adjust separated time connection, long service life, measurement data is accurate, reduces the result and actual value finally measured Deviation.Grounding rod 33 is L shape, and grounding rod 33 by hand drill both can be tapped frequently to avoid hammer, caused to connect Stick 33 caput in ground can be spent, and scratching fingers are easy when taking out from soil, and can solve when encountering compared with dry soil or clay, Grounding rod is difficult to the case where extracting.Connecting rope 4, corresponding connecting rope is respectively set in first wire-wrap board 1 and 2 side of the second wire-wrap board Connector sleeve 5 is set between 4, is equipped with clip 12 on one end end of a connecting rope 4, connector sleeve 5 opens up along its length First groove 13, the first groove 13 are matched with the width of connecting rope 4, open up the second groove 14, fixing groove on connector sleeve 5 respectively 15 and holding tank 18, the first groove 13 communicated with the second groove 14, the second groove 14 is matched with the width of clip 12, and second is recessed Slot 14 is communicated with fixing groove 15, and fixing groove 15 is communicated with holding tank 18, the fan-shaped limit plate 16 of setting, limit plate in fixing groove 15 16 inside cambered surface is matched with 12 outer surface of clip, opens up limiting slot 17 in the inside cambered surface of limit plate 16, limiting slot 17 with Gear ring is arranged in the outside cambered surface of limit plate 16, first gear is arranged in holding tank 18 for the connecting pin matching ends of clip 12 19, electric shifting fork 24 and fixed plate 25, gear ring are engaged with first gear 19 always, and first gear 19 is mounted on first gear axis 23 On, set key in fixed plate 25, first gear axis 23 can be allocated to by electric shifting fork 24 to be cooperated with key, is arranged on electric shifting fork 24 At least two fixed links 21 are arranged in fixing groove 15 for far module, open up the sliding slot 22 of arc on limit plate 16, and fixed link 21 In in sliding slot 22, limit plate 16 can be rotated in fixing groove 15 by sliding slot 22 along fixed link 21, another connecting rope 4 and company Female connector 5 connects.This structure can facilitate the connection between two connecting ropes 4, in order to realize the first wire-wrap board 1 and second around The connection and separation of line plate 2, when connection, two connecting ropes 4 play the work for drawing the first wire-wrap board 1 and the second wire-wrap board 2 respectively With connector sleeve 5 plays the role of that manpower is facilitated to mention, and after connection, people can grasp connector sleeve 5 for the first wire-wrap board 1 and Two wire-wrap boards 2 lift, and after separation, the first wire-wrap board 1 and the second wire-wrap board 2 can be stored respectively, convenient for collecting and arrangement.Connection When, close up clip 12, clip 12 is made to be fixed on the end of connecting rope 4, clip 12 and connecting rope 4 are pushed into the second groove 14 respectively With the first groove 13, after clip 12 enters the second groove 14, connecting pin end enters the limiting slot 17 on limit plate 16, rotation Connector sleeve 5 or connecting rope 4, make limit plate 16 turn to the other side, so that first gear 19 be driven to rotate, after the completion of rotation, lead to Control electric shifting fork 24 is crossed, it is allocated to by first gear axis 23 and cooperates with key, so that first gear axis 23 be made not transport circumferentially It is dynamic, make limit plate 16 that can not be rotated back to original position, since connecting rope 4 can only be moved along the first groove 13, and clip 12 is due to it The limiting slot 17 that connecting pin end is limited on plate 16 blocks, and causes it that can not move along the second groove 14, to make connector sleeve 5 Connecting rope 4 and clip 12 is fixed, connect adjacent connecting rope 4.When disengaging, electric shifting fork 24 is controlled, makes it by the first tooth Wheel shaft 23 is dialled from the key in fixed plate 25, then by rotation connection set 5 or connecting rope 4, makes 16 homing of limit plate, then will even Splicing 4 and 12 backtracking of clip are disconnected from sleeve 5.This connection type is connected and disconnected from conveniently.
As shown in fig. 6, opening up connecting hole 6 and link slot 7 in the connector sleeve 5, connecting hole 6 and link slot 7 are communicated, even Second gear axis 9, second gear axis 9 and first gear axis 23 are arranged in access slot 7 to link by transmission device, second gear axis 9 The first rack gear 10 and the second rack gear 11 are engaged in upper setting second gear 8,8 two sides of second gear respectively, and 10 lower end of the first rack gear is logical It crosses first crossbar and connects several first clamp bars 27,11 upper end of the second rack gear connects several second clamp bars 28 by second crossbar.Such as Shown in Fig. 7, several first clamp bars 27 and several second clamp bars 28 are respectively positioned in connecting hole 6, several first clamp bars (27) and several Axial direction of second clamp bar (28) respectively along connecting hole (6) is arranged successively, and the other end of connecting rope 4 is located at several first clamp bar, 27 Hes Between several second clamp bars 28.This structure can be such that one end of connector sleeve 5 and another connecting rope 4 is connected with each other, before connection, One end of another connecting rope 4 is put between several first clamp bars 27 and several second clamp bars 28, to another connecting rope 4 After one end is connect with connector sleeve 5, first gear axis 23 can generate rotation, and second gear axis 9 drives rotation by first gear axis 23 Turn, so that several first clamp bars 27 and several second clamp bars 28 is moved towards and one end of another connecting rope 4 is clamped, clamp another Behind one end of a connecting rope 4, first gear axis 23 is allocated to by the electric shifting fork 24 in connector sleeve 5 to be cooperated with key, to make first Gear shaft 23 can not circumferential movement, i.e. second gear axis 9 can not rotate, to complete the fixation to another connecting rope 4.It is this Structure realizes the linkage locking and opening of two connecting ropes 4, avoids one of disengagement, convenient for storaging and connecting.
Torsional spring 29 is set on the second gear axis 9.This structure can store power, solution by torsional spring 29 in locking When lock, torsional spring 29 reverses second gear axis 9, so that two connecting ropes 4 be made to disengage automatically with connector sleeve 5.
Several first clamp bars 27 and several second clamp bars 28 are interlaced.This structure can make several first folders 4 fixation of connecting rope is avoided connecting rope 4 from being disconnected from sleeve 5 by item 27 and several second clamp bars 28.
Circular first clamping opening 34 and circular second clamping opening 35, the first clamping opening 34 and ground connection are opened up on the collet 31 Stick 33 matches, and the second clamping opening 35 is matched with lantern ring 30.This structure can increase collet 31 and grounding rod 33 and lantern ring 30 Contact area conducts electricity very well, and facilitates connection and is connected firmly.
Technical solution of the present invention is not restricted in the range of embodiment of the present invention.The not detailed description of the present invention Technology contents be well-known technique.
