[0002] The significant weight of the 500kV grounding wire presents numerous challenges in practical operation. Particularly during connection, safety distance restrictions necessitate greater time and effort from personnel to ensure accurate and stable connection to the designated position. This not only increases operational complexity but also significantly reduces work efficiency.

[0003] Secondly, the weight of the grounding wire increases the operational risks during the connection process. Overcoming greater gravity requires greater physical exertion from workers, increasing the likelihood of accidents. Furthermore, prolonged connection operations can lead to worker fatigue, further increasing the risk.

[0004] Furthermore, the storage of existing 500kV grounding wires after removal also presents challenges. Due to their weight and size, grounding wires require more space, time, and manpower for storage. This not only increases maintenance costs but may also lead to damage to the grounding wires during storage, thus affecting their lifespan and safety.

[0005] In summary, using 500kV grounding wires for grounding operations presents several challenges, including inconvenience, low efficiency, time consumption, and difficulty in storage. These issues not only affect the efficiency and safety of grounding wire connection and storage but also increase maintenance costs.

[0006] Therefore, in order to solve the above problems and reduce the risks of grounding wires, it is particularly urgent and important to design a new type of gun-type device for connecting 500kV grounding wires. Utility Model Content

[0030] 1. This utility model discloses a gun-type device for attaching a 500kV ground wire, comprising a launching bracket, which includes a launching tube and a support tube. The launching bracket, as the main body of the device, is used to install the ground wire, control the launching of the ground wire, and retrieve it. A receiving device is used to store the ground wire. The launching device applies an impact force to the ground wire, causing it to launch onto the cable.

[0057] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0058] like Figures 1-4As shown, the present invention provides a gun-type device for connecting a 500kV ground wire, which includes a launching bracket 1. The launching bracket 1 serves as the main body of the device and is used to install the ground wire 4 and control the launching and retrieval of the ground wire 4.

[0059] The transmitting bracket 1 includes a transmitting tube 2 and a supporting tube 3. The transmitting tube 2 is fixed to the end of the supporting tube 3. The transmitting tube 2 is equipped with a receiving device and a transmitting device. The receiving device is used to receive the grounding wire 4, and the transmitting device is used to give the grounding wire 4 an impact force, so that the grounding wire 4 is launched onto the cable.

[0060] The launching device is fixed to the side of the receiving device. When the operator does not open the device, the grounding wire 4 is stored inside the receiving device. When the operator opens the device, the grounding wire 4 is subjected to force and thus bursts out of the launching tube 2 and is hung on the cable.

[0061] The storage device contains a grounding wire 4. When the grounding wire 4 is placed inside the storage device, it is launched by the transmitting device and then bursts out from the transmitting tube 2 and is attached to the cable. When removing it, the grounding claw 6 is removed and the storage device is reversed so that the grounding wire 4 is rewound inside the storage device, thus completing the storage of the grounding wire 4.

[0062] The side of the firing tube 2 is equipped with a sight 5 for aiming at the cable position. The sight 5 is a very complete component and requires no special modification. Any existing sight 5 on the market can be selected. For example: mechanical sight 5, optical sight 5 scope, tubular sight 5, laser sight 5, low light / night vision sight 5, rail clip sight 5, flashlight bracket sight 5, etc.

[0063] The grounding wire 4 is provided with a grounding claw 6 at its end for hanging on the cable. The hook-shaped structure on the grounding claw 6 is hooked on the cable, so that the grounding wire 4 is hung on the cable. Preferably, the number of hook-shaped structures is not fixed and can be adjusted according to the actual situation.

[0064] In this embodiment, the grounding claw 6 has three hook-shaped structures, so that no matter which side of the grounding claw 6 contacts the cable, there will be a hook-shaped structure hanging on the cable.

[0065] The side of the launch bracket 1 is equipped with a trigger 7 for controlling the launch device. When the operator pulls the trigger 7, the launch device controls the grounding wire 4 to start launching.

[0066] The side of the transmitting tube 2 is equipped with a rotating wheel 8 for controlling the storage device. After the grounding claw 6 is removed from the cable, the operator controls the rotating wheel 8 to rotate, which drives the rotating shaft 16 inside the storage device to rotate, and re-stores the grounding wire 4 inside the storage device.

[0067] In this embodiment, the three gun-type devices for connecting 500kV ground wires are a group. Each transmitter tube 2 has a pre-made hole 9 on its side for the grounding wire 4 to extend out. After the grounding wire 4 extends out of the pre-made hole 9, it is short-circuited with the other two phase grounding wires 4 to the grounding stake, so that the other end of the grounding wire 4 is grounded, thus completing the grounding of the cable.

[0068] The side of the launch tube 2 is equipped with an auxiliary handle 10 for the operator to grip. To use this device, the operator holds the auxiliary handle 10 with one hand and pulls the lever with the other.

[0069] When using this device, one person holds up the launching bracket 1 while another person aims at the top of the pole or line. After the grounding contact is fixed, press the launch button. The grounding claw 6 will launch to the corresponding height and then fall due to its own weight, thus attaching to the pole or line.

[0070] The transmitting device includes a power component, which consists of a coil and wires at both ends of the coil. The grounding claw 6 of the grounding wire 4 receives the force of transmission through the coil, causing it to pass through the coil and be attached to the cable.

[0071] The storage device includes a first limiting plate 14 and a second limiting plate 15. A rotating shaft 16 and a protective plate 11 are arranged between the first limiting plate 14 and the second limiting plate 15. The grounding wire 4 is arranged in the space formed by the first limiting plate 14, the second limiting plate 15 and the protective plate 11. The first limiting plate 14, the second limiting plate 15 and the protective plate 11 limit the grounding wire 4, thereby preventing the grounding wire 4 from being scattered.

[0072] The protective plate 11 is provided with a discharge hole 12 for the grounding wire 4 to extend out. The grounding wire 4 extends out from the discharge hole 12 and is connected to the grounding stake.

[0073] The end of the rotating shaft 16 is connected to the rotating wheel 8. When the operator rotates the rotating wheel 8, the rotating shaft 16 rotates and the grounding wire 4 is stored inside the storage device.

[0074] Several power components are provided. This ensures that grounding wire 4 has sufficient transmission power during the transmission to the cable.

[0075] The support tube 3 is a telescopic tube, which allows the height of the transmitting tube 2 to be adjusted to accommodate cables of different heights.

[0076] A connecting ring 13 is provided at the end of the grounding wire 4. When removing the grounding wire, a special grounding rod can be used to hook the grounding ring for storage. After the grounding wire is removed, the grounding rod is stored in the storage device inside the transmitting tube 2 by rotating the wheel 8.

[0077] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
