Description

[0002] In live distribution network operations, the integrated operation method has become a common operation method for live distribution network operations.

In the field of electrical operations, the integrated operation method may refer to the combined use of multiple insulating tools and equipment such as insulating gloves, insulating rods, insulating platforms, etc. to adapt to different working environments and needs.

[0003] At present, most of the bypass cable splicing work uses insulating gloves to splice the bypass cable head to the live wire. This method has more shielding and requires more handling tools. The hands should be used to directly touch the wire. Usually, an insulating boom truck and an insulating scaffolding are used as the main insulation. For lines with dangerous roads in mountainous areas, the handling tools and the main insulation assembly consume a lot of physical energy of the operators and the working time is long, which causes the line to be out of service for a long time, which has a great impact on the reliability of power supply. In addition, in the prior art, the bypass cable head is usually remade into a gun wire clamp splice, so the cable head cannot be restored. However, we have limited cables at work and cannot spare multiple sets of cable equipment. Therefore, this method brings inconvenience to the work. Therefore, there is an urgent need for an adapter that is easy to disassemble, which can freely use an insulating rod to splice the bypass cable without damaging the cable head, and can also use the insulating glove operation method to splice the bypass cable.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying 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.

[0028] See also Figure 1 The embodiment of the present application provides a lap joint structure, including a first hook head 1 and a second hook head 2, the first hook head 1 includes a first main body 11 and a first slider 12, the first slider 12 is slidably connected to the first main body 11, the first main body 11 is used to hook the cable, and the first slider 12 is used to press the cable tightly; the second hook head 2 is connected to the first hook head 1, the second hook head 2 includes a second main body 21 and a second slider 22, the second slider 22 is slidably connected to the second main body 21, the second main body 21 is used to hook the wire, and the second slider 22 is used to press the wire tightly.

[0029] In actual application, the bypass cable head is hooked on the first hook head 1, and then the first slider 12 is moved, and the first slider 12 presses the bypass cable head against the first hook head 1 to fix the bypass cable head and prevent the bypass cable from shaking; the second hook head 2 is used to hook on the main line, and when the second hook head 2 is hung on the main line, the second slider 22 moves in the direction close to the main line until the second slider 22 presses against the main line, and the second hook head 2 is fixed with the main line to prevent the second hook head 2 from being separated from the main line or moving along the main line, so that the bypass cable can be overlapped on the live main line. When disassembling, the operator only needs to remove the first slider 12 to disassemble the bypass cable head, and remove the second slider 22 to remove the second hook head 2 from the main line. The structure is simple, the operation is convenient, and the device is small in size and light in weight. In some more complex terrains, such as lines with dangerous roads in mountainous areas, the device is easy to transport and can be reused to save operating costs.

[0030] In actual operation, the cable head hook can be hung on the first hook 1 first, and then the second hook 2 can be hung on the main conductor. In the tight circuit, the insulating gloves operation method can be used for overlapping. In the farther circuit, the gun operating rod can be used to hang the second hook 2 on the main conductor. You can switch freely between the insulating gloves operation method and the insulating rod operation method.

[0031] At present, the integrated operation method has become a commonly used operation method in live distribution network operations. The integrated operation method is an operation method that combines multiple operation methods or technologies. It includes multiple components such as insulating gloves, insulating rods, insulating platforms, etc., and is suitable for complex or high-risk electrical operation scenarios.

[0032] Therefore, compared with the prior art, the lap joint structure of the present application can quickly lap the cable head and lap the cable head on the main line, which is easy to operate. By adopting the first hook head 1 and the second hook head 2, both the insulating glove operation method and the insulating rod operation method can be used for lap joint. Without damaging the bypass cable head, both the insulating rod and the insulating glove operation method can be used to lap the bypass cable, thereby improving the safety and efficiency of the operation. Moreover, the first hook head 1 and the second hook head 2 are firmly connected and stable. The drainage line can also be tapped on the lap joint structure to reduce the power outage time of the line, reduce the risk of personnel construction, and improve the human-machine efficiency. Moreover, it is easier to install and disassemble, and is compatible with the insulating glove operation method and the insulating rod operation method. After the work is completed, the cable head is removed and stored, which does not take up space, is convenient for transportation, saves the physical strength of the operator, reduces the use of tools, and gets rid of the difficulty of work caused by terrain conditions, thereby reducing working time, improving work efficiency, and avoiding the inability to carry out operations due to geographical restrictions.

[0033] It should be noted that bypass cables are cables used to temporarily replace or bypass the original power lines, and are usually used during power system maintenance, emergency repairs or upgrades. They allow electricity to continue to flow during maintenance or construction, reducing the impact on users. Bypass cables are usually made of highly conductive materials, can withstand high current loads, and are designed for rapid deployment and removal.

[0034] It needs to be reiterated that the insulating glove method is a live working method, which is mainly used for maintenance and repair work on medium and low voltage power systems. This method allows operators to work while keeping the power system energized to reduce power outage time and improve power supply reliability. In the insulating glove method, operators wear special insulating gloves that can withstand specific voltages and protect operators from electric shock. The insulating rod method is a method of live working using a special insulating rod. The insulating rod is usually made of high-strength insulating material that can withstand high voltages and prevent current from passing through. Operators use insulating rods to touch and operate live parts, thereby avoiding direct contact with live parts and reducing the risk of electric shock. This method is suitable for live parts that require remote operation or are difficult to directly approach, such as high-altitude work or work in narrow spaces.

[0035] See again Figure 1 The overlapping structure also includes a first rotating member 3 and a second rotating member 4. The first rotating member 3 is rotatably connected to the first main body 11 and connected to the first slider 12; the second rotating member 4 is rotatably connected to the second main body 21 and connected to the second slider 22.

[0036] There can be two first rotating members 3, which are symmetrically arranged at the two ends of the first main body 11. In this case, there are also two first sliders 12, which are respectively connected to the two first rotating members 3. The two first sliders 12 move closer to each other until they are pressed against the bypass cable head from the opposite sides of the bypass cable head, so as to form a state of clamping the bypass cable head, thereby fixing the bypass cable head and preventing the bypass cable head from shaking. The first rotating member 3 passes through the first main body 11 and is rotatably connected to the first main body 11. Specifically, the first rotating member 3 can be threadedly connected to the first main body 11, and the first rotating member 3 can be rotatably connected to the first slider 12. In this way, when the operator rotates the first rotating member 3, the first rotating member 3 drives the first slider 12 to move. Similarly, when the operator rotates the second rotating member 4, since the second rotating member 4 is connected to the second slider 22, the second rotating member 4 drives the second slider 22 to move, so that the second slider 22 is pressed against the main conductor.

[0037] It can be understood that the first rotating member 3 can be rotatably connected to the first main body 11, and the first rotating member 3 can be threadedly connected to the first slider 12. When the first rotating member 3 is rotated, the first slider 12 slides along the length direction of the first rotating member 3. Similarly, the second rotating member 4 can also be configured similarly.

[0038] During the operation, the bypass cable head is first hung on the first hook 1, and then the operator rotates the first rotating parts 3 on both sides of the first hook 1, and the first rotating parts 3 on both sides drive the first sliders 12 on both sides to approach each other, and the first sliders 12 on both sides clamp the bypass cable head in the middle to prevent the bypass cable head from shaking. Then the operator uses insulating gloves or insulating rods to hang the second hook 2 on the main conductor, and then rotates the second rotating part 4, and the second rotating part 4 drives the second slider 22 to move, and the second slider 22 moves in the direction close to the main conductor until the second slider 22 presses the main conductor against the second hook 2 to fix the second hook 2 and the main conductor together.

[0039] It should be noted that the first rotating member 3 and the second rotating member 4 can be bolts, and specifically, the first rotating member 3 can be a plum blossom bolt. A plum blossom bolt is a special type of bolt, and its main feature is that its head is designed in a hexagonal plum blossom shape. This design allows the plum blossom bolt to be tightened and loosened with a plum wrench (also called a hexagonal wrench) without slipping off. The second rotating member 4 can be a longer bolt to facilitate the operation of the operator.

[0040] More specifically, an anti-slip sleeve is provided at the end of the second rotating member 4. When the operator needs to manually rotate the second rotating member 4, the operator holds the anti-slip sleeve, which can increase friction and effectively prevent the operator's hand from slipping, resulting in operational errors.

[0041] See again Figure 1A clamping hole 41 is formed at one end of the second rotating member 4, and the clamping hole 41 is used for clamping the gun operating rod.

[0042] In actual applications, when the working environment involves high-voltage power systems, such as maintenance and inspection of high-voltage lines, or in narrow or confined spaces, personnel may not be able to directly approach or operate electrical equipment, or in some high-risk electrical operations, such as operations under severe weather conditions such as heavy rain and strong winds, or emergency repairs that need to be performed under live conditions, the use of insulating rods can increase the safety of the operation. The use of insulating rods can ensure a safe distance between the operator and the power source to prevent electric shock accidents.

[0043] Therefore, the device can realize the insulating rod operation method by setting the clamping hole 41. When the insulating rod operation method is needed, the bypass cable head is first connected to the first hook head 1, and the first rotating part 3 is rotated. The first rotating part 3 drives the first slider 12 to move to fix the bypass cable head to prevent it from shaking; then the clamping hole 41 is hooked with the shooting gun operating rod, and the operator moves the shooting gun operating rod to drive the second rotating part 4 to move to the specified position, and the second rotating part 4 drives the second hook head 2 to move until the operator hangs the second hook head 2 on the main conductor. Then the operator rotates the shooting gun operating rod, and the shooting gun operating rod drives the second rotating part 4 to rotate, and the second rotating part 4 drives the second slider 22 to move. The second slider 22 moves in the direction close to the main conductor, and the main conductor is pressed against the second hook head 2, so as to realize the lap connection of the bypass cable on the main conductor.

[0044] It is understandable that the operating rod of the shooting gun adopts an insulating rod.

[0045] Of course, when using the insulating gloves operation method, the operator can also directly hold the second rotating part 4 after fixing the bypass cable head, and move it to a preset position to facilitate the second hook head 2 to be hung on the main conductor. The operator then rotates the second rotating part 4, and the second rotating part 4 drives the second slider 22 to move, thereby fixing the main conductor and the second hook head 2, thereby realizing the function of splicing the bypass cable by the insulating gloves operation.

[0046] See also Figure 2 The first main body 11 includes a U-shaped member 111 and a connecting member 112. The U-shaped member 111 is connected to the second hook head 2. The connecting member 112 is connected to the open end of the U-shaped member 111. The first slider 12 is slidably connected to the connecting member 112, and the connecting member 112 is used to hook the cable.

[0047] In actual application, the U-shaped member 111 and the connecting member 112 are arranged to form a polygonal space, and the bypass cable head is provided with a hanging groove, through which the bypass cable head is hung on the connecting member 112, and then the first rotating member 3 is rotated to drive the first slider 12 to move so that it is pressed against the bypass cable head to prevent it from shaking; when it needs to be disassembled, the bypass cable head can be removed by simply rotating the first rotating member 3 in the opposite direction to drive the first slider 12 away from the bypass cable head. The U-shaped member 111 and the connecting member 112 are arranged to form a polygonal space to prevent the bypass cable head from slipping, thereby increasing the connection stability of the bypass cable head.

[0048] It is understandable that the U-shaped member 111 can also be replaced by other structures, not only limited to the "U" shape, but also other shapes, such as a triangle or a polygon. When a triangle or a polygon is used, one of the sides is open, and the connecting member 112 is connected to one side of the opening.

[0049] See again Figure 2 The connecting member 112 is provided with an arc surface 1121 along its length direction, and the arc surface 1121 is provided on a side of the connecting member 112 facing the first sliding block 12 .

[0050] Specifically, the connecting piece 112 can be in the shape of a semi-cylinder, and the semi-cylinder has an arc surface 1121. The arc surface 1121 of the semi-cylinder faces the first slider 12, that is, the side of the connecting piece 112 that contacts the bypass cable head is the arc surface 1121. This is conducive to hooking the bypass cable head, and the contact surface is very wide. The arc surface 1121 of the semi-cylinder can just clamp with the cable head, which is simple to operate and convenient to use.

[0051] See also Figure 3 The second main body portion 21 includes an arc portion 211 and a support portion 212. The arc portion 211 is connected to the top of the support portion 212. The second slider 22 is slidably connected to the support portion 212 and can slide toward the direction close to the arc portion 211. The arc portion 211 is used to hook the wire.

[0052] In actual application, along the height direction of the support portion 212, the arc portion 211 is connected to the top of the support portion 212, and the arc portion 211 is arranged in an arc shape so as to be hung on the main conductor. The second slider 22 is slidingly connected to the support portion 212, and one end of the second rotating member 4 passes through the support portion 212 and is connected to the second slider 22, and the second rotating member 4 is rotatably connected to the support portion 212. The operator rotates the second rotating member 4, and the second rotating member 4 drives the second slider 22 to move in the direction close to the arc portion 211 until the second slider 22 is pressed against the main conductor to fix the second hook head 2 on the main conductor.

[0053] It can be understood that the second sliding block 22 slides along the height direction of the supporting portion 212 .

[0054] See also Figure 3 The second slider 22 is provided with an extrusion surface 221 on one side facing the arc portion 211, and the extrusion surface 221 is an arc surface. Specifically, since the outer surface of the main conductor is usually circular, the arc surface of the extrusion surface 221 is adapted to the outer surface of the main conductor, and when the second slider 22 moves toward the direction close to the main conductor, the extrusion surface 221 fits with the outer surface of the main conductor, which can better press against the main conductor and increase the connectivity between the main conductor and the second hook 2.

[0055] The second slider 22 is also provided with an inclined surface 222, which is connected to the side of the extrusion surface 221 close to the support portion 212. The inclined surface 222 is a plane, and along the direction close to the support portion 212, the inclined surface 222 is inclined in the direction away from the arc-shaped portion 211. The inclined surface 222 is provided with a slide groove 223, and the slide groove 223 is slidably connected to the support portion 212. Specifically, the inclined surface 222 extends downward along the height direction of the support portion 212, which effectively avoids the second slider 22 from colliding with the support portion 212 when sliding, so that the second slider 22 slides more smoothly, thereby improving the working efficiency.

[0056] See again Figure 2 The first main body portion 11 is connected to a side of the support portion 212 away from the arc-shaped portion 211 , one end of the first main body portion 11 is connected to the support portion 212 , and the other end is inclined in a direction away from the support portion 212 .

[0057] In actual applications, in order to facilitate the installation and disassembly of the bypass cable head, the open end of the U-shaped member 111 is inclined away from the support portion 212, that is, the connecting member 112 is away from the support portion 212, and a distance is provided between the support portion 212 and the connecting member 112. This makes it easier for operators to install and disassemble the bypass cable head and avoids collision with the support portion 212 during operation, which would affect normal operation.

[0058] See also Figure 3 The second main body portion 21 includes an extension portion 213, which is connected to a side of the arc portion 211 away from the support portion 212. The extension portion 213 extends in a direction away from the support portion 212, and the extension portion 213 tends to gradually converge; along the height direction of the support portion 212, the extension portion 213 is inclined in a direction away from the arc portion 211.

[0059] Specifically, the extension portion 213 extends in a direction away from the support portion 212 and is inclined downward along the height direction of the support portion 212. In normal use, the extension portion 213 enlarges the contact area between the second hook head 2 and the main conductor, which can help the operator to hook the main conductor in long-distance operation, making it easier for the arc portion 211 to hang on the main conductor, further simplifying the operation process. The gradual contraction trend of the extension portion 213 can effectively save the volume of the extension portion 213, reduce production costs, reduce the weight of the device, and facilitate operation by the operator.

[0060] See also Figure 3 and Figure 4 The overlapping structure includes a fixing piece, the first hook head 1 is provided with a plurality of first fixing holes 13, the second hook head 2 is provided with a plurality of second fixing holes 23, and the fixing piece passes through the first fixing holes 13 and the second fixing holes 23 to fix the first hook head 1 and the second hook head 2.

[0061] In practical applications, the first hook 1 and the second hook 2 can be connected together in a detachable manner. For example, the first hook 1 is provided with a plurality of first fixing holes 13, and the second hook 2 is provided with a plurality of second fixing holes 23. The fixing parts pass through the first fixing holes 13 and the second fixing holes 23 to fix the first hook 1 on the second hook 2, so as to facilitate overlapping the bypass cable head on the main conductor.

[0062] It is understandable that the fixing parts may be screws or bolts to facilitate the disassembly of the first hook 1 and the second hook 2; in other embodiments, the first hook 1 and the second hook 2 may also be fixedly connected, such as by welding, to increase the connection stability of the first hook 1 and the second hook 2. The present application does not limit the connection method of the first hook 1 and the second hook 2.

[0063] The utility model also provides an electric power device, including the above-mentioned overlapping structure and cable.
