Description
Technical Field
[0001] This utility model belongs to the field of power supply equipment technology, specifically, it relates to a capacitor voltage divider power supply device that can be installed while energized. Background Technology
[0002] Sometimes it is necessary to install some measuring equipment on power transmission lines. Some measuring equipment needs to draw power from the power transmission lines. However, low-voltage power cables generally have insulating sheaths. When there are no exposed terminals available for wiring near the installation location of the measuring equipment, the traditional practice is to break the insulating sheath of the cable and connect the power supply through the break to the equipment.
[0003] Existing power collection devices typically use hooks to initially secure high-altitude power transmission lines. Although the hooks can be directly fixed to the transmission lines, ground personnel need to support the hooks with connecting rods during subsequent power collection and installation. Otherwise, the hooks are prone to swaying and shifting on the line. While personnel can manually support them to alleviate this problem, it interferes with subsequent piercing operations and reduces the efficiency of device installation. Furthermore, after the hooks are fixed, most devices use telescopic connecting rods for piercing installation. The force exerted by these rods acts directly on the transmission lines, which can easily cause the hooks to become entangled in the lines. This can not only deform the transmission lines but also damage them with long-term use, making the devices quite inconvenient to use. In view of this, this utility model is hereby proposed.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: The included pressure plate allows workers to easily control its alignment with the power-collecting hook via a pull rope.

Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Please see Figure 1-7As shown, this embodiment provides a capacitor voltage divider power extraction device that can be installed energized, including a power extraction hook 1, a pressure plate 101 slidably fitted on one side of the power extraction hook 1, a cavity provided inside the power extraction hook 1, a first toothed plate 102 and a second toothed plate 104 slidably fitted inside the cavity, a gear 103 meshing between the first toothed plate 102 and the second toothed plate 104, the first toothed plate 102 elastically fitted inside the cavity, the second toothed plate 104 connected to the pressure plate 101, and a pull rope 3 installed at the end of the first toothed plate 102; A fixed cylinder 2 is fixed to one side of the power hook 1. A piercing element 4 is detachably installed at the end of the fixed cylinder 2. A lead screw 201 is threaded into the fixed cylinder 2. A telescopic connecting cylinder 202 is installed on the lower side of the fixed cylinder 2. A telescopic control rod 5 is rotatably fitted inside the telescopic connecting cylinder 202. One end of the telescopic control rod 5 is engaged with the lead screw 201. A collar 110 is installed on one side of the power hook 1. The lead screw 201 is threaded into the collar 110. Specifically, a guide groove is provided on one side of the fixed cylinder 2. The collar 110 is threaded into the lead screw 201 through the guide groove. With the setting of the guide groove, the moving fixed cylinder 2 can be limited and guided, making the movement of the fixed cylinder 2 more stable.
[0019] In use, first connect the telescopic connecting cylinder 202 to the fixed cylinder 2, then hang the power hook 1 on the power transmission line to be powered. After hanging, pull the pull rope 3. The pull rope 3 will drive the first toothed plate 102 to move, and the second toothed plate 104 will move through the gear 103. When the second toothed plate 104 moves, it will drive the pressure plate 101 to move closer to the power hook 1, so that the power transmission line between the pressure plate 101 and the power hook 1 is tightly clamped, which improves the stability of the power hook 1 on the power transmission line and provides convenience for subsequent operations. After the power hook 1 is initially hung, the staff can hold the telescopic connecting cylinder 202 with one hand and rotate the telescopic control rod 5 with the other hand. The telescopic control rod 5 drives the lead screw 201 to rotate. The lead screw 201 will drive the fixed cylinder 2 to move under the limit of the collar (110), thereby driving the piercing part 4 to move towards the power hook 1, thereby controlling the piercing part 4 to penetrate the insulation of the power transmission line and creating conditions for subsequent power collection work.
[0020] The pressure plate 101 allows workers to easily control it to move towards the power hook 1 via the pull rope 3. This not only facilitates the placement of the power hook 1 on the power transmission line but also reduces the likelihood of it shaking or moving around, making subsequent power extraction more stable. The piercing element 4 can penetrate the insulation layer on the power transmission line surface, facilitating subsequent power extraction and enhancing its stability. The telescopic control rod 5 allows ground personnel to control the rotation of the screw 201 inside the fixed cylinder 2, thereby controlling the raising and lowering of the piercing element 4. This allows ground personnel to control the penetration of the piercing element 4 into the insulation layer of the power transmission line surface and to extract power. The telescopic connecting cylinder 202 allows ground personnel to control the use of the power hook 1 on the fixed cylinder 2, and also enables power extraction from power transmission lines at various heights, increasing the usability of the power hook 1 at different heights.
[0021] In this embodiment, a locking block 109 is elastically fitted on one side of the first toothed plate 102. Specifically, a storage frame is fixed to one side of the first toothed plate 102, and a spring is installed between the inner wall of the storage frame and the locking block 109. A first fixing block 105 and a second fixing block 106 are installed on one side of the inner wall of the cavity in this embodiment. The first fixing block 105 is fixed to one side of the inner wall of the cavity, and the second fixing block 106 is slidably fitted to one side of the inner wall of the cavity. A slot is formed between the first fixing block 105 and the second fixing block 106, and the slot engages with the locking block 109. Both the outer sides of the first fixing block 105 and the second fixing block 106 in this embodiment are chamfered, and the locking block 109 has a bevel on the side facing the first fixing block 105. Specifically, the first fixing block 105 is located above the second fixing block 106. The locking block 109 in this embodiment enables the rapid fixing and release of the power hook 101 from the power transmission line. When the pull rope 3 moves the first toothed plate 102, the locking block 109 first contacts the first fixed block 105. With the help of the chamfer of the first fixed block 105 and the inclined surface of the locking block 109, the locking block 109 retracts into the storage frame and compresses the spring. When the locking block 109 moves with the pull rope 3 to the first toothed plate 102 between the first fixed block 105 and the second fixed block 106, the locking block 109 is locked into the slot formed by the two under the action of the spring force, thereby completing the fixation of the pressure plate 101 and the power supply hook 1, laying a stable foundation for subsequent power supply. To remove the power hook 1, first pull the pull cord 3 again, causing the locking block 109 on one side of the first toothed plate 102 to continue moving. At this time, the locking block 109 in the slot will first push the second fixing block 106 downward. When the second fixing block 106 reaches the lowest point, the inclined surface of the locking block 109 will press against the chamfer of the second fixing block 106, causing the locking block 109 to retract into the storage frame. As the pull cord 3 moves, the locking block 109 will move below the second fixing block 106. Then, release the pull cord 3. Under the action of the elastic force (because the first toothed plate 102 is elastically fitted in the cavity), the first toothed plate 102 will drive the locking block 109 and the second fixing block 106 upward together, so that the chamfers of the first fixing block 105 and the second fixing block 106 are aligned and fitted. At this time, the second fixing block 106 cannot move due to the fit. The locking block 109, under the action of the inclined surface, will then... The first retracts into the storage frame; when the locking block 109 moves above the first fixing block 105, the first fixing block 105 will be compressed by the second fixing block 106, compressing the spring and retracting into the storage frame. Subsequently, the first toothed plate 102 resets due to the loss of its limit and drives the pressure plate 101 on the second toothed plate 104 to move away from the power hook 1 through the gear 103, releasing the fixation on the power transmission line. This makes the removal of the power hook 1 on the high-altitude power transmission line more convenient and efficient, while improving the safety of the operation. Among them, an insulating rubber pad is installed on the upper side of the pressure plate 101. Since the pressure plate 101 itself is in close contact with the power transmission line before release, the insulating rubber pad can be compressed to continue moving upward when the pressure plate 101 is in contact with the positioning, which facilitates the further release of the positioning of the pressure plate 101 on the power transmission line.
[0022] The piercing component 4 in this embodiment includes a mounting block 402. Multiple piercing needles 403 are fixed to the upper side of the mounting block 402. The mounting block 402 is detachably mounted on the end of the fixing cylinder 2. A threaded mounting head 401 is mounted on the end of the fixing cylinder 2 in this embodiment. A threaded groove is provided on the lower side of the mounting block 402, and the threaded mounting head 401 is threadedly engaged with the threaded mounting head 401 through the threaded groove. The threaded mounting head 401 facilitates quick mounting and dismounting of the mounting block 402, thereby simplifying the replacement of the piercing needles 403 on the mounting block 402. When the piercing needles 403 become worn or damaged due to long-term use and need to be replaced, simply rotate the mounting block 402 to remove the old part and replace it with a new mounting block 402 containing the piercing needles 403, thus improving the replacement efficiency of the piercing needles 403.
[0023] In this embodiment, fixed posts 203 are installed on opposite sides of one end of the fixed cylinder 2, and fixed grooves 204 are provided on opposite sides of one end of the telescopic connecting cylinder 202. The fixed groove 204 in this embodiment includes a V-shaped guide groove 205 and an embedding groove 206, which are connected. The embedding groove 206 cooperates with the fixed posts 203. The V-shaped guide groove 205 facilitates the smooth insertion of the fixed posts 203 on the telescopic connecting cylinder 202; while the design of the embedding groove 206 ensures that the fixed posts 203 entering the V-shaped guide groove 205 are stably engaged therein, thereby achieving convenient connection between the fixed cylinder 2 and the telescopic connecting cylinder 202. This not only facilitates direct operation by ground personnel but also improves the ease of operation of the power hook 1.
[0024] In this embodiment, a connecting block 207 is installed at one end of the lead screw 201, and a splicing groove 208 is provided on one side of the connecting block 207. A splicing block 209 is provided at one end of the telescopic control rod 5, and the splicing groove 208 is engaged with the splicing block 209. By setting the splicing block 209, it can be engaged with the splicing groove 208 on the connecting block 207, thereby facilitating the splicing of the telescopic control rod 5 and the lead screw 201. This allows the operator to control the movement of the piercing part 4 on the lead screw 201 by using the telescopic control rod 5 while standing on the ground, which facilitates subsequent power supply operations and further improves the convenience of using the piercing part 4. Both the splicing block 209 and the splicing groove 208 here are cross-shaped structures, which facilitates the engagement of the splicing blocks 209 and 208. The shapes of the splicing blocks 209 and the splicing groove 208 can also refer to the straight or polygonal structures in the prior art. Without affecting the normal use of this device, no limitation is made here.
[0025] In this embodiment, a mounting plate 107 is installed on one side of the power hook 1, and a fixing ring 108 is installed on one side of the mounting plate 107. The fixing ring 108 facilitates the positioning of the conductive line connected to the power hook 1, allowing the conductive line to be stably installed within the fixing ring 108. This reduces the likelihood of the conductive line swaying or swinging back and forth due to factors such as wind during use, making the power-generating device more stable when drawing power.
[0026] In this embodiment, both the retractable connecting cylinder 202 and the retractable control rod 5 are made of insulating material, which can further improve the safety of workers.
[0027] In this embodiment, retaining rings are installed inside both ends of the telescopic connecting cylinder 202, and annular grooves are opened on the outer sides of both ends of the telescopic control rod 5. The telescopic control rod 5 is inserted into the retaining ring through the annular groove, so that the telescopic connecting cylinder 202 can drive the telescopic control rod 5 to extend and retract synchronously during the extension and retraction process, thereby facilitating the control of the power hook 1 to be stably hung on the power transmission line where power needs to be drawn.
