[0002] In a building's electrical wiring, ground protection devices ensure that leakage or overcurrent in the power system is quickly conducted to the ground, preventing harm to personnel or damage to electrical equipment. Ground protection devices are critical components for grounding distribution boxes, outlets, and electrical equipment. They are particularly widely used in environments like high-rise buildings and underground garages. Many industrial equipment (such as machine tools, robotic arms, and power tools) operates in high-power environments and in the presence of conductive materials such as water and metal dust, posing a high risk of leakage. In industrial production, ground protection devices prevent operators from being harmed by leakage from equipment, while also providing effective overcurrent protection for precision instruments and reducing failure rates.

[0003] However, some existing ground wire protection devices based on radio and television engineering usually place the ground wire directly into the inside of the device when in use, so that the device clamps the ground wire, thereby enabling the device to protect the ground wire. However, it does not take into account the direct clamping and fixing of the ground wire. When the device needs to protect different positions of the ground wire, it is more troublesome to move it. Therefore, a ground wire protection device based on radio and television engineering is proposed to solve the above problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 and Figure 4 The utility model provides an embodiment of a ground wire protection device based on radio and television engineering, comprising a shell 1, wherein two fixing rods 2 are fixedly connected to the front and rear sides of the interior of the shell 1, so that the shell 1 can provide support for the fixing rod 2, and the top and bottom of the fixing rod 2 are slidably connected to the sliding plate 4, and then the sliding plate 4 can be limited when moving by the setting of the fixing rod 2, and the top and bottom of the fixing rod 2 are sleeved with a spring 3, one end of the spring 3 is fixedly connected to the inner wall of the shell 1, and the other end of the spring 3 is fixedly connected to the outside of the sliding plate 4, and then the sliding plate 4 will compress the spring 3 when it moves, and the outside of the sliding plate 4 is fixedly connected to a bearing assembly for carrying the moving structure, so that the bearing assembly will drive the sliding plate 4 to move when it moves, and the outside of the bearing assembly is rotatably connected to a rotating wheel 6, and then the rotating wheel 6 will drive the bearing assembly to move when it moves;

[0026] Reference Figure 1 and Figure 3 The bearing assembly includes a plurality of fixed shafts 5, one side of the fixed shaft 5 is fixedly connected to the outside of one of the sliding plates 4, and the other side of the fixed shaft 5 is fixedly connected to the outside of the other sliding plate 4, so that when the fixed shaft 5 is subjected to force, the two sliding plates 4 are driven to move through the fixed shaft 5, and the middle part of the rotating wheel 6 is rotatably connected to the outside of the fixed shaft 5, so that the rotating wheel 6 drives the fixed shaft 5 to move when it moves;

[0027] Reference Figures 1 to 2 , wire holes 7 are opened on the left and right sides of the outside of the shell 1, so that the ground wire can enter the interior of the shell 1 through the setting of the wire holes 7, and a plurality of fixed plates 8 are fixedly connected to the inside of the shell 1, so that the shell 1 can provide support for the plurality of fixed plates 8, and the outsides of the plurality of fixed plates 8 are fixedly connected to the wire tubes 9, and then the plurality of fixed plates 8 can provide support for the wire tubes 9, and the plurality of rotating wheels 6 are all arranged inside the shell 1, and the outsides of the plurality of sliding plates 4 are in contact with the inner wall of the shell 1, so that the movement of the sliding plates 4 can be more stable.

[0028] Working Principle: When the device is initially used, the ground wire enters the interior of the housing 1 through the wire holes 7 on the left and right sides of the housing 1. The provision of wire holes 7 allows the ground wire to easily enter the interior of the device, providing a channel for subsequent protection and fixation. After entering the housing 1, the ground wire enters the interior of the conduit 9. The conduit 9 is supported by multiple fixing plates 8, ensuring a stable layout of the ground wire within the device. This stability is provided by the design of the fixing plates 8 supporting the conduit 9, which effectively prevents the ground wire from becoming entangled within the device.

[0029] After entering the device, the ground wire is routed along the interior of housing 1, supported by conduit 9. Conduit 9 not only physically supports the ground wire but also serves as a first layer of protection, preventing friction or displacement within the device. Furthermore, conduit 9 provides a degree of isolation for the ground wire, preventing it from being directly affected by the external environment, further enhancing its safety.

[0030] The sliding plate 4 within the device is held in a predetermined position by the retaining function of the fixed rods 2. The fixed rods 2 are connected to both sides of the housing 1 and are fitted with springs 3 at the top and bottom. Guided by the fixed rods 2, the sliding plate 4 maintains a defined trajectory. As the sliding plate 4 moves, the springs 3 compress and return to their initial position when the sliding plate 4 stops moving. This structural design ensures that the sliding plate 4 can be flexibly adjusted when needed while remaining stable against deviation from its predetermined trajectory, enhancing the device's internal structural stability.

[0031] The support assembly attached to the exterior of the sliding plate 4 plays a key role in this structure. The rotating wheels 6 on the support assembly ensure smooth movement of the sliding plate 4, thereby driving the support assembly's smooth movement within the housing 1. The provision of the rotating wheels 6 allows the sliding plate 4 to slide over ground wires of varying thicknesses, ensuring the device can accommodate ground wires of varying specifications and providing precise protection.

[0032] The multiple fixed shafts 5 of the load-bearing assembly are connected to the outer sides of the two sliding plates 4. When a force is applied to one sliding plate 4, the fixed shafts 5 drive the opposing sliding plate 4 to move synchronously. This function of the fixed shafts 5 ensures the linkage between the two sliding plates 4, allowing the device to maintain balance during sliding, preventing deviation due to unilateral force. This design not only improves the overall stability of the device, but also makes it more durable.

[0033] During operation, the rotating wheel 6 drives the fixed shaft 5 in motion. The rolling function of the rotating wheel 6 enables the sliding plate 4 and the load-bearing assembly to move smoothly within the housing 1, effectively preventing excessive resistance caused by friction from the ground wire. The rotating wheel 6 also adapts to ground wires of varying thicknesses through the action of the spring 3, maintaining a stable rolling effect even when the ground wire specifications change.

[0034] After the ground wire is arranged and positioned, the device ensures stable operation within the device. The exterior of the sliding plate 4 contacts the inner wall of the housing 1, ensuring smooth sliding within the housing 1 and preventing instability caused by friction or external forces. The stability of the sliding plate 4 within the housing 1 also supports the long-term operation of the entire device, ensuring the service life of the ground wire protection device in various environments.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
