[0031] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] In the embodiment of the present utility model, Figure 1-Figure 4As shown, the 10KV line live lap drainage device includes a first insulating rod 1, a second insulating rod 2 and a connecting piece; the first insulating rod 1 has a first end and a second end arranged opposite to each other, the first end is formed with a hanging point for detachably hanging on the conductor, and the second end is formed with a supporting point for supporting the drainage line; the second insulating rod 2 has a third end and a fourth end arranged opposite to each other, the third end is formed with a clamping point for clamping or releasing the end of the drainage line, and the fourth end is provided with a handle; the connecting piece includes a first sheath 3 and a second sheath 4 that are rotatably matched, the first sheath 3 and the second sheath 4 are respectively sleeved on the first insulating rod 1 and the second insulating rod 2, so that the first insulating rod 1 and the second insulating rod 2 can rotate relative to each other.

[0033] Specifically, in the embodiment of the utility model, the operation steps of live overlapping drain wire are: stripping off the insulation layer of appropriate length on the main conductor (hereinafter referred to as "conductor") and the drain wire, adjusting the opening angle of the wire clamp and fixing it on the installation tool, passing the bent drain wire through the drain wire groove of the wire clamp and fixing it, hanging the wire into the wire groove of the wire clamp through the insulating operating rod, and tightening the wire clamp bolt through the insulating operating rod. In this process, the drain wire needs to be suspended below the wire. Since the drain wire is heavy, it needs to be supported by hand or with tools; and the overlapping needs to be operated within a safe distance. The different overlapping positions require workers to constantly adjust the angle of the drain wire, and the preliminary preparation time is relatively long.

[0034] In the embodiment of the utility model, the upper and lower ends of the first insulating rod 1 are defined as the first end and the second end respectively. A hanging point is set at the first end, which is used to hang the first insulating rod 1 on the wire so that the first insulating rod 1 is vertically suspended below the wire; a supporting point is formed at the second end of the first insulating rod 1, which is used to support the drainage line, so that the weight of the drainage line is borne by the first insulating rod 1 through the wire, and the whole is insulated, with high safety, which can effectively prevent the occurrence of electric shock accidents; at the same time, the drainage line does not need to be held after being suspended, reducing the ratio of workers.

[0035] In an embodiment of the utility model, the upper and lower ends of the second insulating rod 2 are defined as the third end and the fourth end respectively, and a clamping point is formed at the third end of the second insulating rod 2 for clamping or releasing the end of the drain wire to facilitate the overlapping of the drain wire and the conductor; the fourth end of the second insulating rod 2 is provided with a handle for holding the second insulating rod 2.

[0036] In the embodiment of the utility model, the first insulating rod 1 and the second insulating rod 2 are rotatably matched with each other through a connecting piece, and the connecting piece includes a first sheath 3 and a second sheath 4 that are rotatably connected. The first sheath 3 and the second sheath 4 are respectively sleeved on the outer surfaces of the first insulating rod 1 and the second insulating rod 2, so that the two insulating rods can rotate relative to each other; in this way, the angle between the first insulating rod 1 and the second insulating rod 2 is adjusted by holding the handle, so that the end of the drainage line can freely adjust the direction and deflection, which is convenient for overlapping; at the same time, when the two axes of the first insulating rod 1 and the second insulating rod 2 are parallel (such as Figure 2 It is easy to carry and does not take up much space when not in use.

[0037] The utility model hangs the first insulating rod 1 on the conductor through the hanging point, and suspends the drainage line below the conductor by using the supporting point; at the same time, the relative rotation of the first insulating rod 1 and the second insulating rod 2 is realized through the connecting piece, so that the clamping point formed on the second insulating rod 2 can rotate with it, so that the end of the drainage line clamped at the clamping point can rotate freely, and the angle and distance of the drainage line can be quickly adjusted by holding the handle and rotating the second insulating rod 2; the drainage line can be energized and overlapped within a safe distance, thereby improving the working efficiency.

[0038] like Figure 1-3 As shown, in one embodiment, the hanging point is an insulating hook 5 fixed to the first end. Specifically, in order to hang the first insulating rod 1 on the wire, this embodiment fixes an insulating hook 5 on the first end of the first insulating rod 1, and the insulating hook 5 has a closed end and an open end, and the open end is arranged downward, so that the first insulating rod 1 can be quickly hung vertically on the guide through the insulating hook 5, thereby fixing the first insulating rod 1.

[0039] Furthermore, in one embodiment, at least one clip 6 is provided in the insulating hook 5, and the two ends of the clip 6 are respectively located at the closed end and the open end of the insulating hook 5. Specifically, in order to clamp the wire in the insulating hook 5, the present embodiment provides a plurality of clips 6 in the insulating hook 5 (two clips 6 arranged in mirror image form a group), so that the insulating hook 5 with clips 6 can be quickly hooked to the wire; at the same time, since the clip 6 has a certain deformation amount, it is also convenient to quickly detach from the wire after not in use, which has the advantages of high efficiency, labor saving and stable operation compared to manually operating the insulating bucket arm vehicle to adjust the angle and orientation up and down so that the drainage line slides close to the wire.

[0040] like Figure 1-3As shown, in one embodiment, the support point includes a support frame 7 arranged at the second end, and a slider 8 slidably arranged on the support frame 7. Along the sliding direction of the slider 8, the opposite end faces of the support frame 7 and the slider 8 are respectively formed with a first arc groove and a second arc groove, and a support opening 9 is defined between the first arc groove and the second arc groove for supporting the drainage line. Specifically, in order to fix the drainage line to the second end of the first insulating rod 1, this embodiment is provided with a support frame 7 on the second end of the first insulating rod 1, and the support frame 7 is formed with a semi-enclosed installation opening, and the slider 8 is slidably arranged in the above-mentioned installation opening; at the same time, a support opening 9 is formed between the slider 8 and the support frame 7, and the drainage line is passed through the support opening 9, and the slider 8 is slid to change the size of the support opening 9, so that the drainage line is fixed in the support opening 9 to avoid the drainage line from being separated during the overlap; on the other hand, the sliding slider 8 is also convenient for applying drainage lines of different wire diameters to achieve fast and stable locking of the drainage line. Of course, since the cross-section of the drainage line is a circular structure, the support opening 9 is composed of two arc-shaped grooves, which are respectively a first arc-shaped groove and a second arc-shaped groove formed on the opposite surfaces of the support frame 7 and the slider 8 .

[0041] Furthermore, if Figure 3 As shown, in one embodiment, the slider 8 is provided with a first threaded rod 10, which is inserted into the support frame 7 and locked by a locking nut. Specifically, in order to enable the slider 8 to slide back and forth in the up and down directions, a first threaded rod 10 is inserted into the support frame 7, and the first threaded rod 10 extends into the installation opening and is connected to the slider 8, and the middle part is locked on the support frame 7 by a locking nut; in this way, the locking nut is turned forward and reversed to make the slider 8 slide or hover in the installation opening, so as to achieve the purpose of changing the size of the support opening 9. Of course, in order to facilitate operation, a handle is provided on the locking nut to increase the contact area between the locking nut and the palm.

[0042] Preferably, the second end and the support frame 7 are connected via a second threaded rod 11. Changing the exposed length of the second threaded rod 11 can not only make the angle of the support frame 7 adjustable, but also increase or decrease the overall length of the first insulating rod 1 to adapt to different overlapping scenarios. Of course, in other embodiments, the second threaded rod 11 can also be replaced with a telescopic rod that telescopes up and down.

[0043] like Figure 4As shown, in one embodiment, the clamping point includes a wire fixing bracket 12 disposed at the third end, and a holding block 13 slidably disposed on the wire fixing bracket 12, and along the sliding direction of the holding block 13, a clamping opening 14 is defined between the wire fixing bracket 12 and the holding block 13 for clamping or releasing the end of the drainage wire. Specifically, in order to fix the end of the drainage wire on the third end of the second insulating rod 2, a wire fixing bracket 12 is disposed at the third end of the second insulating rod 2, and a holding block 13 that can slide in the up and down directions is disposed on the wire fixing bracket 12, so that a clamping opening 14 is formed between the fixing bracket and the holding block 13 for clamping the end of the drainage wire; in this way, the size of the clamping opening 14 is changed by sliding the holding block 13 to clamp or release the end of the drainage wire therebetween, so as to facilitate long-distance overlapping of the drainage wire. Similarly, in order to meet the appearance requirements of the drainage wire, the opposite end faces of the wire fixing bracket 12 and the supporting block 13 are both formed with C-shaped notches.

[0044] Further, in one embodiment, the wire fixing bracket 12 is provided with a matching screw rod 15 and a T-nut 16, one end of the screw rod 15 is connected to the supporting block 13, and the other end thereof is provided with a first gear 17 for meshing with a second gear 18 provided at the third end. Specifically, in order to drive the supporting block 13 to slide back and forth in the wire fixing bracket 12, the present embodiment is provided with a first gear 17 and a second gear 18, the first gear 17 is connected to the supporting block 13 through the screw rod 15, and the second gear 18 is rotatably provided at the third end of the second insulating rod 2; at the same time, a T-nut 16 is provided on the wire fixing bracket 12 for matching with the screw rod 15; when the second gear 18 is driven to rotate under the action of an external force, the first gear 17 meshing therewith can be linked to rotate, and the rotational force can be converted into a linear motion through the cooperation of the screw rod 15 and the T-nut 16, so that the supporting block 13 can approach or move away from the notch of the wire fixing bracket 12, thereby changing the size of the clamping opening 14. Gear meshing transmits better force and higher efficiency.

[0045] Of course, since the operator is at the low end and the clamping port 14 is located at the high end, in order to achieve the purpose of driving the second gear 18 to rotate at a low position, a rotating shaft (not shown) is set along the length direction of the second insulating rod 2, which is used to connect the second gear 18 and the handle. When the handle is turned at a low position, the second gear 18 is rotated via the rotating shaft; the rotating shaft is hidden in the second insulating rod 2, so that the rotation of the rotating shaft is not affected.

[0046] On the other hand, in order to prevent the end of the drainage line from being separated after the clamping opening 14 is gradually opened due to misoperation during the overlapping process, the drainage device also includes a limiting structure, such as Figure 6As shown, the limiting structure includes a first limiting seat 22 and a second limiting seat 23. One end of the first limiting seat 22 is connected to the rotating shaft so as to rotate in the same direction as the rotating shaft, and the other end is arranged opposite to the second limiting seat 23. The opposite surfaces of the two are provided with one-way teeth, and the second limiting seat 23 can move relative to the first limiting seat 22, so that the second limiting seat 23 can be in contact with or not in contact with the first limiting seat 22. When the two are in contact, the first limiting seat 22 and the second limiting seat 23 are meshed, and under the action of the one-way teeth, the first limiting seat 22 can only rotate in the same direction. The rotation direction can gradually reduce the clamping opening 14, thereby preventing the end of the drainage line from detaching from the clamping opening 14 and avoiding the clamping opening 14 from loosening or reversing. On the contrary, when the two are not in contact, the first limiting seat 22 can be reversed without restraint, so that the clamping opening 14 can be enlarged or reduced. It can be understood that if Figure 7 As shown, the handle can be divided into two parts, one part can drive the rotating shaft to rotate, and the other part can be provided with an anti-slip and anti-retreat switch, which has two travel points, one of which is that the first limit seat 22 and the second limit seat 23 are in contact, and the other is that the first limit seat 22 and the second limit seat 23 are not in contact.

[0047] like Figure 4 , Figure 5 As shown, in one embodiment, the third end is provided with a protrusion 19, the wire fixing bracket 12 is rotatably arranged on the protrusion 19, and the protrusion 19 and the wire fixing bracket 12 are relatively fixed by a butterfly bolt;

[0048] The rotation angle of the wire fixing bracket 12 is defined as α, and α satisfies 0°≤α≤90°. Specifically, in order to adjust the angle of the end of the drainage line in a wider range, the present embodiment sets two protrusions 19 in a mirror image at the third end of the second insulating rod 2, and the wire fixing bracket 12 and the protrusions 19 are connected by butterfly bolts; loosening the butterfly bolts can make the fixing bracket rotate relative to the protrusions 19, and tightening the butterfly bolts can make the two relatively fixed, so as to fix the fixing bracket at multiple angles; of course, since the first gear 17 needs to be driven by the second gear 18, the rotation angle of the wire fixing bracket 12 should be between 0°-90°, so that the first gear 17 and the second gear 18 are always engaged.

[0049] like Figure 3 , Figure 8As shown, in one embodiment, the first insulating rod 1 is provided with a slide groove 20 along its length direction, and the first sheath 3 is provided with an adjusting nut 21, which is used to extend into any position of the slide groove 20; specifically, in order to change the height of the second insulating rod 2, a slide groove 20 arranged along its length direction is provided on the surface of the first insulating rod 1, and an adjusting nut 21 is provided on the first sheath 3, and the adjusting nut 21 can extend into any position height of the slide groove 20, so as to position the second insulating rod 2 at any height of the first insulating rod 1 through the two sheaths. By adjusting the up and down distance through the ring-clip slide groove 20, the first sheath 3 slides up and down more smoothly and more stably, and the point hole is used to adjust the up and down distance, and loading and unloading are also more convenient.

[0050] Preferably, the second sheath 4 is a snap-fit ​​structure for quickly holding the second insulating rod 2, so as to realize quick assembly and disassembly of the first insulating rod 1 and the second insulating rod 2, and facilitate carrying.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
