Description

Technical Field

[0001] The present invention relates to the technical field of waterproofing of wire joints, and specifically to a wire waterproof connection structure and a connection method thereof. Background Art

[0002] To improve the standards of power grid construction and meet the needs of the majority of users, the government and power departments have increased their investment in distribution network facilities. All 10 kV and 0.4 kV lines use insulated wires. Insulated wires can reduce the accident rate and improve the power supply reliability rate. During the operation of the distribution network, due to the non-standard connection of insulated wires and long-term rainy weather, water seeps into the insulation layer. Through the load current, the cable insulation heats up, the resistance increases, the metal inside the cable oxidizes, causing the cable insulation to burn out and form a short circuit, resulting in safety accidents and burning out electrical equipment. In the traditional wire connection method, the connection part of the wire is prone to water seepage, leading to faults such as short circuits and corrosion. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] To solve the above problems of the prior art, the present invention provides a wire waterproof connection structure and a connection method thereof. Through the unique downward design of the wire joint end, combined with the filling of the gap by the waterproof sealant after curing, it can effectively prevent rain, dew, etc. from seeping along the wire into the connection part.

[0005] (2) Technical Solutions

[0006] To achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A wire waterproof connection structure and a connection method thereof, including a utility pole, a cross arm, a buffer mechanism, a wire, and a parallel groove clamp. The connection end of the wire is fixed by the parallel groove clamp, and the end of the connection end of the wire is perpendicular to the ground downward. The parallel groove clamp includes a first clamp body and a second clamp body. The first clamp body and the second clamp body are symmetrically provided with clip grooves for cooperating with the wire. A groove is provided in the middle position of the second clamp body. A waterproof sealant bag is arranged in the inner cavity of the groove. Channels communicating with the clip grooves are arranged on both sides of the groove. An extrusion block for cooperating with the groove is arranged on the first clamp body. Through the unique downward design of the wire joint section, combined with the filling of the gap by the waterproof sealant after curing, it can effectively prevent rain, dew, etc. from seeping along the wire into the connection part.

[0008] Preferably, one end of the clip groove is a sealed structure, and the sealed end of the clip groove faces the ground.

[0009] Preferably, fixing holes are provided on both the first clamp body and the second clamp body, and the first clamp body and the second clamp body are fixedly connected by bolts.

[0010] A wire waterproof connection method includes the following steps:

[0011] Step 1: Peel off the insulating skin at the connection end of the wire, and the peeled length is equal to the depth of the clamping wire groove;

[0012] Step 2: Cut the insulating skin at the insulating end of the wire. After cutting, 1 - 2 cm of the insulating skin is reserved, and the reserved insulating skin is turned outward in the direction perpendicular to the wire;

[0013] Step 3: Combine the first clamping body and the second clamping body on the parallel groove clamp and connect them with bolts.

[0017] (III) Beneficial effects

[0018] The present invention provides a wire waterproof connection structure and its connection method. It has the following beneficial effects:

[0019] (1). The wires are connected through the parallel groove clamp, and the design that the joint end of the wire faces downward can utilize the gravity effect to make the liquid water that may adhere to the wire surface slide down naturally, avoiding accumulation at the connection end. At the same time, most of the natural winds in the outside world are horizontal. The setting with the joint facing downward can increase the windward area of the joint and the natural wind, accelerating the drying speed of the joint position.

[0020] (2). Through the design of the internal waterproof sealing glue bag and the extrusion block in the parallel groove clamp, the waterproof sealant can seal the gaps of the parallel groove clamp to provide a waterproof barrier.

[0021] (3). The reserved insulating skin can block the opening end of the clamping wire groove. Combined with the waterproof sealant, it can better seal the opening end of the clamping wire groove to prevent rainwater, etc. from entering the clamping wire groove. Description of the drawings

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 - 3 shown, the waterproof connection structure of the wire in this embodiment includes an electric pole 1, a cross arm 2, a buffer mechanism 3, a wire 4 and a parallel groove clamp 5. The connection end of the wire 4 is fixed by the parallel groove clamp 5. The end of the connection end of the wire 4 is perpendicular to the ground downward. The joint of the wire is connected by the parallel groove clamp 5. The design that the joint end of the wire faces downward can utilize the gravity to make the liquid water that may adhere to the surface of the wire 4 slide down naturally, avoiding accumulation at the connection end. The parallel groove clamp 5 includes a first clamp body 501 and a second clamp body 502. Clamping grooves 6 for cooperating with the wire 4 are symmetrically opened on both the first clamp body 501 and the second clamp body 502. A groove 7 is opened in the middle position of the second clamp body 502. A waterproof sealant bag 8 is arranged in the inner cavity of the groove 7. Channels 9 communicating with the wire clamping grooves 6 are arranged on both sides of the groove 7. An extrusion block 10 cooperating with the groove 7 is arranged on the first clamp body 501. The extrusion block 10 breaks the waterproof sealant bag 8, and the waterproof sealant inside the waterproof sealant bag 8 can fill the gaps on the parallel groove clamp 5 to waterproof and seal the joint of the wire 4.

[0028] As a specific embodiment of the present invention, one end of the wire clamping groove 6 is a sealed structure, and the sealed end of the wire clamping groove 6 faces the ground.

[0029] As a specific embodiment of the present invention, fixing holes 11 are opened on both the first clamp body 501 and the second clamp body 502, and the first clamp body 501 and the second clamp body 502 are fixedly connected by bolts.

[0030] A wire waterproof connection method includes the following steps:

[0031] Step 1: Strip the insulating skin at the connection end of the wire 4, and the stripped length is equal to the depth of the wire clamping groove 6;

[0032] Step 2: Cut the insulation of the insulated end of the wire 4, leaving 1 - 2 cm of the insulation after cutting, and turn the remaining insulation outwards in the direction perpendicular to the wire 4; the remaining insulation can cover the opening end of the clip groove 6.

[0033] Step 3: Merge the first clip body 501 and the second clip body 502 on the parallel groove clamp 5 and connect them with bolts. Insert the metal ends of the stripped wire 4 into the clip grooves 6 respectively, and then adjust the position of the remaining insulation so that the insulation adheres to the opening of the clip groove 6.

[0034] Step 4: Tighten the bolts to connect and fix the first clip body 501 and the second clip body 502.

[0035] Step 5: Adjust the position of the parallel groove clamp 5 so that the insertion end of the wire 4 in the clip groove 6 faces upward, and then fix the wire 4 with a cable tie.

[0036] As a specific embodiment of the present invention, in Step 1, the insulation is cut from three positions along the diameter direction of the wire 4, and the widths of the cut insulation are equal.

[0037] Working principle: The wire 4 is connected through the parallel groove clamp 5. The parallel groove clamp 5 is arranged perpendicular to the ground. The joints of the wire 4 are connected through the parallel groove clamp 5. The design that the joint end of the wire 4 faces downward can utilize the gravity to make the liquid water that may adhere to the surface of the wire 4 slide down naturally, avoiding accumulation at the connection end.

[0038] When connecting the joints of the wire 4 through the parallel groove clamp 5, first cut the insulation at the joint position of the wire 4 from three positions along the diameter direction of the wire 4, and the widths of the cut insulation are equal. Then insert the joint of the wire 4 into the clip groove 6, and arrange the position of the insulation. The three pieces of insulation open outwards and adhere to the parallel groove clamp 5. When connecting the first clip body 501 and the second clip body 502 with bolts, the extrusion block 10 on the first clip body 501 will extrude the waterproof sealant bag 8. After the waterproof sealant bag 8 is broken, the waterproof sealant passes through the channel 9 to fill the gaps on the parallel groove clamp 5, the gaps between the joint of the wire 4 and the clip groove 6, and the gaps between the insulation and the end of the parallel groove clamp 5. After the waterproof sealant is cured, it can seal the gaps to prevent rainwater from entering the gaps. At the same time, since the insulation covers the insertion end of the clip groove 6 on the parallel groove clamp 5 and cooperates with the waterproof sealant for sealing, it can further prevent rainwater from entering the gaps between the joint end of the wire 4 and the clip groove 6.
