DETAILED DESCRIPTION

[0038] There is a widespread hidden danger of missing insulating sheaths at the pole-mounted drop-out fuse posts. When there are bird nests, tree branches or other foreign objects in such equipment, phase-to-phase short circuits are very likely to occur, causing the 10kV line to trip and shut down. At present, the work of eliminating the hidden danger of missing insulating sheaths of fuses often encounters situations where the terrain is complex and live working vehicles cannot enter. According to statistical data, the rate of eliminating the hidden danger of missing insulating sheaths without power outages in the jurisdiction within one year is only 76%. Therefore, the present invention proposes to develop an installation tool that can eliminate the hidden danger of missing insulating sheaths without power outages when live working vehicles cannot enter to work, thereby increasing the success rate of eliminating the hidden danger of missing insulating sheaths of drop-out fuses without power outages from 76% to 100%.

[0039] During the development process, we found two operating methods that can be used as reference;

[0040] The first type: the structure and installation method of live installation tools for transformer insulation sheath;

[0041] Principle description: The live installation tool for transformer insulation sheath consists of a pliers head and an insulating rod. There is a groove on the top of the pliers head and a card slot on the inside for fixing the insulation sheath. The insulating rod increases the safe operating distance and improves safety.

[0042] The second method: Learn from the way a mechanical claw holds objects and moves flexibly;

[0043] Principle description: The robotic claw simulates the opening and closing of the hand and clamps the goods, and realizes flexible rotation, angle adjustment and telescopic control through the coordination of multiple joints of the robotic arm.

[0044] Specifically, in Example 1, please refer to the attached Figures 1 to 3The present invention provides a technical solution: a non-stop power-on installation tool for an insulating sheath of a drop-out fuse, comprising: a connecting rod 1, a connecting arm 3, a clamping plate 6 and a long rod 7, wherein the connecting arm 3 is designed in a U shape, the clamping plates 6 are arranged at the two ends of the U shape on the connecting arm 3, and the two clamping plates 6 can be relatively engaged and separated, and a connecting box 4 is also arranged at the two ends of the U shape on the connecting arm 3, and a rotating rod 5 for connecting the clamping plates 6 is rotatably arranged on the connecting box 4, and a driving mechanism such as a motor is arranged in the connecting box 4 to drive the rotating rod 5 to rotate, thereby driving the clamping plates 6 to rotate, so as to realize the relative engagement and separation between the two clamping plates 6.

[0045] The connecting rod 1 is arranged at the middle position of the bottom of the U-shape on the connecting arm 3, and the connecting rod 1 is used to connect with the long rod 7. When installing the insulating sheath, the two clamping plates 6 are used to bite and fix the insulating sheath. The insulating sheath is located in the U-shape on the connecting arm 3, and then the long rod 7 is manually operated to lift the insulating sheath to the position as shown in FIG. Figure 5 The bottom position of the fuse 9 on the electric pole 8 shown in the figure is then controlled to engage or separate a pair of clamps 6 so that the insulating sheath is wrapped around the outside of the fuse 9. Buckles and Velcro are provided on the insulating sheath, and the insulating sheath is engaged and wrapped around the outside of the fuse 9 to fix it. This replaces the installation method of power outage or the installation method of using a working vehicle with a point in the prior art. The installation is simple and convenient, is not restricted by the site, and has a low installation cost.

[0046] It should be noted that an electrical box 2 is provided on the connecting rod 1, and the electrical box 2 is used to store power, etc., to power the motor and other mechanisms in the connecting box 4. The electrical box 2 is also used in conjunction with a handheld remote control to facilitate the control of the splint 6 to achieve the purpose of biting or separation. This is existing technology and will not be elaborated here.

[0047] The long rod 7 can be in the form of a straight rod, without splicing, which is more convenient to use, but troublesome to carry.

[0048] In Example 2, reference Figures 5 to 7 As shown in the figure, the long rod 7 is set as a spliced ​​rod body. Specifically, the long rod 7 is composed of a plurality of short rods 18. The inner circle of the upper end of the short rod 18 has an internal thread 20, and the lower end of the short rod 18 is integrally provided with a threaded end 19. The upper and lower adjacent short rods 18 can be connected in the internal thread 20 by threaded cooperation of the threaded end 19 to achieve end-to-end connection, which is convenient for splicing and use according to the different heights of the fuse 9, and is easy to carry.

[0049] Considering that the long rod 7 is relatively long as a whole, and taking into account the need for lightness when in use, a carbon fiber rod body is usually used for it. However, the carbon fiber rod body has a certain elasticity. When the long rod 7 is extended too long, the elastic effect of the long rod 7 will cause the clamping plate 6 to shake, making it impossible for the clamping plate 6 to maintain a stable state and dock with the fuse 9. It is necessary to wait until the position of the clamping plate 6 is stable before docking, which reduces the installation efficiency.

[0050] Therefore, the present invention also provides an auxiliary mechanism for use with the long pole 7 to solve the problem of the splint 6 shaking due to the elastic action of the long pole 7. Specifically, the auxiliary mechanism includes a moving ring 10 and a spring telescopic rod 11. The moving ring 10 is an annular structure, and the annular structure is detachable. When the annular structure is mounted on the outside of the electric pole 8, the annular structure can slide along the height direction of the electric pole 8, and the spring telescopic rod 11 can be elastically telescopic, and the two ends of the spring telescopic rod 11 are respectively hinged between the annular structure and the side of the long pole 7. When the long pole 7 lifts the splint 6 to rise, the moving ring 10 rises along the height direction of the electric pole 8, and the spring telescopic rod 11 adaptively rises and falls, which can support the end of the long pole 7 close to the splint 6, so that the splint 6 is more stable and less likely to shake.

[0051] like Figure 5 The figure shows the state where the long rod 7 is used vertically. Figure 8 The state shown in FIG. 7 is that the long rod 7 is used in an inclined manner.

[0052] As a further extension, Fig. 9 As shown in , a plurality of auxiliary mechanisms may be provided to make the splint 6 more stable.

[0053] In actual conditions, the utility pole 8 is usually a cone structure with a small top and a large bottom. If the movable ring 10 is only a ring structure of fixed size, it cannot be stably lifted and lowered along the height direction of the utility pole 8 adaptively. Therefore, the movable ring 10 with an adaptively adjustable diameter is provided in the present invention, such as Figure 6 As shown in the figure, the movable ring 10 is composed of two semi-annular stainless steel rings 12, both ends of the stainless steel rings 12 are fixedly provided with connecting fixing plates 15, the two connecting fixing plates 15 are connected by a round rod 16, the length of the round rod 16 is long enough, both ends of the round rod 16 are connected with nuts 17 by threaded cooperation, a spring 14 is arranged between the two springs 14, the end of the spring 14 is fixed to the surface of the connecting fixing plate 15 by magnetic fixing, and the magnetic attraction maintains sufficient suction force, so that when the stainless steel ring 12 is sleeved on the outside of the electric pole 8, the spring 14 can pull the two stainless steel rings 12 to fit the outer surface of the electric pole 8, so as to adapt to the change of the outer ring diameter of the electric pole 8, and when the two stainless steel rings 12 are close to or away from each other, the connecting fixing plate 15 slides on the corresponding round rod 16 to adapt.

[0054] The inner side of the stainless steel ring 12 is movably inlaid with a ball 13, and a plurality of balls 13 are provided. The stainless steel ring 12 contacts the outer surface of the electric pole 8 through the ball 13, and slides smoothly. When the connecting rod 1 lifts the splint 6 to rise, the stainless steel ring 12 can slide on the electric pole 8 adaptively.

[0055] In Example 3, reference Figures 10 to 13As shown in the figure, when a hollow cavity 21 is provided inside the short rod 18, a first channel 22 may be correspondingly provided inside the connecting rod 1, the first channel 22 is connected to a hollow cavity 21 above, the hollow cavities 21 in the upper and lower adjacent short rods 18 are connected to each other, a connecting head 23 is connected to the short rod 18 at the bottom, the connecting head 23 is connected to the air pump 25 through a soft air tube 24, and interconnected air flow channels are also provided inside the connecting arm 3 and the connecting box 4, an air outlet hole 26 is provided on the inner side of the connecting box 4, the air outlet hole 26 is connected to the air flow channel inside the connecting box 4, and the air flow channel inside the connecting arm 3 is connected to the first channel 22.

[0056] When working, start the air pump 25, and the air pump 25 can transport the gas to the air outlet 26 through the soft air pipe 24, the connecting head 23, the hollow cavity 21, the first channel 22, the inside of the connecting arm 3 and the inside of the connecting box 4 in sequence. The gas discharged from the air outlet 26 can blow and clean the surface of the fuse 9, so as to maintain the insulation effect of the surface of the fuse 9. At this time, when the insulating sheath is installed on the fuse 9, the insulation effect can be further guaranteed. It has strong practicality and utilizes the design that the connecting rod 1, the connecting arm 3, and the long rod 7 are hollow themselves, which is simple and low in cost.
