Description

Technical Field

[0001] This invention relates to the field of grounding wire technology, and in particular to a portable retractable phase-separated grounding wire device. Background Technology

[0002] Grounding wires are one of the most commonly used safety tools for power outage maintenance of high-voltage transmission lines. During a power outage, it is often necessary to install and remove six sets of three-phase grounding wires. High-voltage grounding wires are long and heavy. Grounding wire devices are used to transport and store grounding wires to prevent them from being dragged and rubbed on the ground, as well as from being tangled and knotted. However, when using existing grounding wire devices, the extension length of the grounding wire cannot be flexibly controlled. After the grounding wire is connected, due to the influence of external environmental factors such as wind, the grounding wire is prone to sag or become taut, which can cause shaking and result in low connection reliability. Summary of the Invention

[0003] To overcome the problem of poor connection reliability caused by the inflexible control of the wiring length of high-voltage grounding wires in the prior art, this invention provides a portable retractable phase-separated grounding wire device that can flexibly adjust and lock the extension length of the grounding wire, avoiding swaying and improving connection reliability.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a portable device for taking in and releasing phase-separated grounding wires is provided, including a take-up reel, a housing and a handle. The take-up reel is provided with a linkage shaft, and the two ends of the linkage shaft are respectively rotatably connected to the side wall of the housing. The handle is connected to the linkage shaft and extends out of the housing. The housing is provided with a wire outlet hole. One end of the grounding wire is wound around the take-up reel, and the other end of the grounding wire extends out from the wire outlet hole. A limiting locking structure is provided between the take-up reel and the housing.

[0005] Furthermore, the limiting locking structure includes a spring positioning pin and a plurality of positioning holes, the plurality of positioning holes being spaced apart on the take-up reel, and the spring positioning pin being mounted on the housing and being insertable into the positioning holes.

[0006] Furthermore, there are two take-up reels, which are arranged side by side inside the housing, and a connecting line is provided between the linkage shafts on each take-up reel.

[0007] Furthermore, the outer casing is provided with several lifting rings.

[0008] Furthermore, the outer shell is provided with a hanging chain, the hanging chain has several branch ends and hook ends, each branch end is connected to the hanging ring, and the hook end has double hook points.

[0009] Furthermore, the handle is provided with a base and a grip, the base is fixed on the linkage shaft, the grip is hinged to the base, and the grip can be folded and stored inside the base.

[0010] Furthermore, the base is a disc structure with an internal recess, and the handle is disposed on the inner circumference of the disc structure.

[0011] Furthermore, a stop structure is provided at one end of the grounding wire extending out of the outlet hole.

[0012] Furthermore, the stop structure is spherical.

[0013] Furthermore, the inner wall of the outer casing is provided with a bracket, and the two ends of the linkage shaft are rotatably connected to the bracket through bearings.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This invention provides a portable device for retracting and extending a phase-separated grounding wire. The operator drives a handle to rotate a linkage shaft, which in turn rotates a take-up reel. The take-up reel winds the grounding wire, increasing or decreasing the length of the end of the grounding wire extending beyond the outer casing. Once the extension length is adjusted appropriately, a limiting locking structure locks the take-up reel to the outer casing, preventing the take-up reel from rotating relative to the casing. This locks the extension length of the grounding wire, preventing it from being pulled out or retracted by external forces. Consequently, the grounding wire cannot sag or become taut, improving the connection stability and reliability. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only one type of embodiment of the present invention, and not all of the embodiments. The present invention will be described in one embodiment below with reference to specific implementation methods. The accompanying drawings are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present patent. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0024] like Figure 1-4 As shown, this embodiment provides a portable device for taking in and releasing a phase-separated grounding wire 6, including a take-up reel 1, a housing 2, and a handle 3. The take-up reel 1 is provided with a linkage shaft 4, and the two ends of the linkage shaft 4 are respectively rotatably connected to the side wall of the housing 2. The handle 3 is connected to the linkage shaft 4 and extends out of the housing 2. The housing 2 is provided with a wire outlet hole 5. One end of the grounding wire 6 is wound around the take-up reel 1, and the other end of the grounding wire 6 extends out from the wire outlet hole 5. A limiting locking structure is provided between the take-up reel 1 and the housing 2.

[0025] During use, the operator drives the handle 3 to rotate the linkage shaft 4, which in turn drives the take-up reel 1 to rotate. The take-up reel 1 winds the grounding wire 6, increasing or decreasing the length of the end of the grounding wire 6 extending out of the outer casing 2. That is, when the handle 3 rotates forward, the length of the grounding wire 6 increases, and when the handle 3 rotates in the reverse direction, the length of the grounding wire 6 decreases. After the length of the grounding wire 6 is adjusted appropriately, the limit locking structure locks the take-up reel 1 to the outer casing 2, preventing the take-up reel 1 from rotating relative to the outer casing 2. This locks the length of the grounding wire 6, preventing the grounding wire 6 from being pulled out or retracted by external forces, which could cause sag or tension, making the connection end of the grounding wire 6 wobble and reducing the reliability of the connection.

[0026] Specifically, in this embodiment, as Figure 2-4 As shown, the take-up reel 1 preferably uses an H-beam reel. The linkage shaft 4 enters from one side of the H-beam reel, passes through the middle cylinder of the H-beam reel, and exits from the other side of the reel. The two ends of the linkage shaft 4 are rotatably connected to the outer casing 2. The grounding wire 6 is wound around the middle cylinder of the H-beam reel and is limited by the two side reels to prevent the grounding wire 6 from loosening.

[0027] Meanwhile, in order to cooperate with the installation of the spring positioning pin 7, effectively lock the grounding wire 6, and flexibly adjust the length of the grounding wire 6, in this embodiment, it is preferable to set positioning holes 8 along the circumference of the wheel on the take-up reel 1, that is, the take-up reel 1 is provided with a ring of positioning holes 8 around its circumference. By inserting one end of the spring positioning pin 7 into the positioning hole 8 on the take-up reel 1, the take-up reel 1 can be locked at any angle, thereby flexibly adjusting the extension length of the grounding wire 6.

[0028] When in use, the connection end of the grounding wire 6 extends out from the outlet hole 5 of the outer casing 2. If it is necessary to lock the extension length of the grounding wire 6, the spring positioning pin 7 can be inserted into the positioning hole 8 on the take-up reel 1 at various angles of rotation, so that the take-up reel 1 cannot rotate relative to the outer casing 2, thereby fixing the extension length of the grounding wire 6. Since the length of the grounding wire 6 is fixed, the tension of the grounding wire 6 is large, and it is not easily affected by external forces such as wind and sags, thereby avoiding shaking at the connection and improving the reliability of the connection.

[0029] Specifically, in this embodiment, as Figure 5-6 As shown, the spring positioning pin 7 has an insertion end 710 and a rotating end 720. Under normal circumstances, the insertion end 710 of the spring positioning pin 7 is in the extended position, that is, the insertion end 710 of the spring positioning pin 7 is located in the positioning hole 8 on the take-up reel 1 in its natural state. The rotating end 720 of the spring positioning pin 7 extends out of the outer shell 2. There are two states between the insertion end 710 and the rotating end 720: pulled out and reset. When the rotating end 720 is rotated 90° in the pulled-out state, the insertion end 710 can be retracted, that is, disengaged from the positioning hole 8 on the take-up reel 1, so that the take-up reel 1 can rotate normally, thereby adjusting the extension length of the grounding wire 6. When the rotating end 720 is released, the rotating end 720 and the insertion end 710 are reset. The insertion end 710 returns to the extended state by the action of the built-in spring force, that is, the insertion end 710 extends into the positioning hole 8 on the take-up reel 1, so that the take-up reel 1 cannot rotate relative to the outer shell 2, thereby locking the extension length of the grounding wire 6.

[0030] Furthermore, such as Figure 2 As shown, to enable bidirectional wiring of the grounding wire 6 device, this embodiment preferably uses two take-up reels 1, which are arranged side by side inside the housing 2. A connecting line 9 is provided between the linkage shafts 4 on each take-up reel 1, making it suitable for on-site grounding wire 6 installation. The grounding wire 6 device adopts a double-sided outgoing wire method, allowing operators to extend at least 5 meters on each side, reaching a total length of 10 meters, depending on the site conditions. Compared to the single-sided outgoing wire wiring method in the prior art, this device is more flexible in its use, has a wider wiring range, and allows for arbitrary extension and locking on both sides. The extension length of the grounding wire 6 is flexible, meaning that the grounding wire 6 device in this embodiment can be used for both single-sided and double-sided wiring, offering flexible application.

[0031] Furthermore, such as Figure 1-2 As shown, in order to facilitate connection with the lug 15 of the grounding wire 6 and improve wiring efficiency, in this embodiment, a stop structure 12 is provided at one end of the grounding wire 6 that extends out of the outlet hole 5. That is, the lug 15 of the grounding wire 6 extends out of the outlet hole 5, and the stop structure 12 is set between the lug 15 of the grounding wire 6 and the outlet hole 5. The stop structure 12 limits the end of the lug 15 of the grounding wire 6, preventing the lug 15 of the grounding wire 6 from being wound into the outer shell 2 when the wire is retracted, which is not conducive to subsequent wiring. Specifically, in this embodiment, the stop structure 12 is preferably designed as a ball. The ball structure is not easily deformed, and the difference between the diameter of the ball and the diameter of the outlet hole 5 is large, which can effectively prevent the grounding wire 6 from being completely retracted into the device due to excessive wire retraction, leaving the lug 15 of the grounding wire 6 outside the device, which is convenient for operation and use, and realizes the wire retraction blocking function.

[0032] Furthermore, in order to improve the structural strength of the device, in this embodiment, the outer shell 2 is preferably formed by laser one-piece cutting, making the device lighter, more reliable and durable as a whole.

[0033] Meanwhile, in this embodiment, as Figure 2-4 As shown, in order to improve the support stability of the housing 2 on the take-up reel 1 and facilitate the flexible rotation of the take-up reel 1, it is preferable to set a bracket 13 inside the housing 2. The two ends of the linkage shaft 4 are respectively rotatably connected to the bracket 13 through bearings 14. The bracket 13 is preferably set as a portal frame, with two portal frames respectively set on both sides of the take-up reel 1, so that the two ends of the linkage shaft 4 are respectively supported on the portal frame. The portal frame improves the support stability of the linkage shaft 4, increases the structural strength, and avoids shaft breakage. In this embodiment, the bearing 14 is installed between the linkage shaft 4 and the portal frame, which facilitates the linkage shaft 4 to drive the take-up reel 1 to rotate and improves rotational stability.

[0034] Furthermore, to facilitate the connection of the grounding device, in this embodiment, it is preferable to provide several lifting rings 10 on the outer shell 2. The device can be suspended and hoisted using the lifting rings 10 for high-altitude wiring. Specifically, in this embodiment, it is preferable to provide a hanging chain on the lifting ring 10, wherein the hanging chain has several branch ends and hanging ends. Each branch end is connected to the lifting ring 10 to balance the force on the device and facilitate disassembly and maintenance. The hanging end has double hanging points, namely a low hanging point and a high hanging point, which facilitates the transportation and fixed connection of the device.

[0035] Specifically, in use, the grounding wire 6 device is applied to the installation and removal of grounding wire 6 on transmission towers. It needs to be transported to the actual working position via a transfer rope and a fixed pulley. During the transmission process, the low hanging point is set on the transfer rope. When the device rises to a certain height, the high hanging point is used to fix the device in a suitable position on site. That is, the operators do not need to repeatedly install and remove the device and can flexibly move the device between various working positions. The height difference of the hanging points greatly reduces the workload of the workers, reduces the risk of falling from height, and achieves the goal of saving time and effort in aerial operations.

[0036] Furthermore, for ease of carrying this device, such as Figure 1 As shown, in this embodiment, the outer shell 2 is also provided with a handle 11, which makes it convenient for operators to carry and move the equipment by hand.

[0037] Furthermore, in this embodiment, as Figure 3-4 As shown, to facilitate the rotation of the take-up reel 1, the handle 3 is provided with a base 310 and a grip 320. The base 310 is fixed on the linkage shaft 4, and the grip 320 is hinged to the base 310. The grip 320 can be folded and stored inside the base 310. That is, when it is necessary to rotate the take-up reel 1, the grip 320 can be extended out of the base 310, that is, the axis of the grip 320 is parallel to the axis of the linkage shaft 4, increasing the lever arm, which makes it easier to drive the grip 320 to drive the base 310 and the linkage shaft 4 to rotate. When it is not necessary to rotate the take-up reel 1, the grip 320 can be stored in the base 310, that is, the axis of the grip 320 intersects with the axis of the linkage shaft 4. This can protect the grip 320 and prevent accidental rotation of the grip 320 from driving the take-up reel 1 to rotate.

[0038] Specifically, in this embodiment, the base 310 is preferably a disc structure with an internal recess. The handle 320 is set on the inner circumference of the disc structure. That is, the internal recess of the disc structure forms a storage space for the handle 320. The handle 320 is set on the inner circumference of the disc structure, which can rotate with the radius of the disc structure as the radius, which is convenient for winding the grounding wire 6 and facilitates smooth winding.

[0039] Furthermore, in this embodiment, the handle 3 can also be replaced by an electric device, that is, by using a drive motor connected to the linkage shaft 4 to realize electric winding or unwinding of the line.

[0040] Working principle:

[0041] The operator drives the handle 3 to rotate the linkage shaft 4, which in turn drives the take-up reel 1 to rotate. The take-up reel 1 winds the grounding wire 6, increasing or decreasing the length of the end of the grounding wire 6 extending out of the outer casing 2. That is, when the handle 3 rotates in the forward direction, the length of the grounding wire 6 increases, and when the handle 3 rotates in the reverse direction, the length of the grounding wire 6 decreases. After the length of the grounding wire 6 is adjusted appropriately, the spring positioning pin 7 is inserted into the positioning hole 8 of the take-up reel 1. The limit locking structure locks the take-up reel 1 to the outer casing 2, so that the take-up reel 1 cannot rotate relative to the outer casing 2, thereby locking the length of the grounding wire 6.

[0042] This device utilizes a limiting and locking structure to prevent the grounding wire 6 from being pulled out or retracted due to external forces, thereby preventing the grounding wire 6 from sag or become taut, ensuring the stability of the connection end of the grounding wire 6 and improving connection reliability. At the same time, the device has a reasonable design structure, which can realize hand-cranked winding or motor winding, improving winding efficiency and achieving efficient organization and storage of the grounding wire 6, avoiding problems such as knotting, time-consuming and labor-intensive use. In addition, the device has a stop structure 12 on the grounding wire 6, which can prevent excessive winding during the winding process and leave the wire lug 15 of the grounding wire 6 outside the device for easy wiring. In addition, the device has a compact structure, is lightweight, easy to carry, and highly practical.
