[0002] Electrical engineering and automation is an engineering discipline involving power systems, electronic circuits, control systems and other fields. It aims to study the design, installation, operation and maintenance of electrical equipment, circuits and automation technology. Electrical engineering involves power generation, transmission, distribution systems, and the design and application of various electrical equipment and electronic components. It also includes the protection, control and monitoring of power systems. The connection parts, terminals and other components of electrical equipment may have wires or cables exposed outside the equipment or system. In order to ensure the safety and reliability of exposed wires, protective devices are essential. Protective devices can include external sheaths, insulating sleeves, protective covers and other equipment to protect exposed wires from mechanical damage, chemical corrosion, electromagnetic interference and other adverse factors. The use of protective devices can reduce the risk of failure of electrical equipment, improve the safety and reliability of equipment, and also help to extend the service life of equipment.

[0003] At present, the existing exposed wire protection devices usually need to select an appropriate number of devices according to the length to be protected, and splice them through bolts to ensure the coverage. However, this practice will add additional workload to the operators because a large number of bolts are required to connect these protection devices. As the number of bolts increases, the operator's work efficiency may be affected to a certain extent because the tightening process of a large number of bolts requires more time and effort; this large-scale bolt tightening work not only increases the labor intensity of the operators, but may also cause fatigue and inconvenience during the operation. The operators need to spend more time and energy to complete the bolt tightening work, which may reduce the overall work efficiency, prolong the working time, and increase the inconvenience and discomfort during the operation.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3, an embodiment provided by the utility model: an exposed wire protection device for electrical engineering and automation, comprising a protective shell 1, a protective shell 2 2 is arranged on the other side of the protective shell 1, the outer walls of the protective shell 1 and the protective shell 2 2 are fixedly connected with a connecting column 3, a connecting hole 4 is opened on the other side of the protective shell 1, the connecting column 3 is slidably connected inside the connecting hole 4, a column 5 is fixedly connected inside the connecting column 3, a spring 7 is sleeved on the outer wall of the column 5, the spring 7 is centrally symmetrical, one end of the spring 7 is fixedly connected inside the connecting column 3, the other end of the spring 7 is fixedly connected with a slider 6, the slider 6 is bilaterally symmetrical, the slider 6 is slidably connected to the outer wall of the column 5, a connecting rod 8 is rotatably connected inside the slider 6, one end of the connecting rod 8 is arranged with a clamping assembly, the clamping assembly comprises a sliding column 9 and a ball 10, the sliding column 9 is rotatably connected to one end of the connecting rod 8, the ball 10 is arranged on one side of the sliding column 9, and the ball 10 is slidably connected to the protective shell 1;

[0032] Specifically, when it is necessary to dock the equipment, the straight part only needs to dock the protective shell 1 with the protective shell 1, while the curved part needs to dock a protective shell 2 2 between the two protective shells 1. When docking the protective shell 1 or the protective shell 2 2, the connecting column 3 will be inserted into the connecting hole 4, triggering the process of the ball 10 being squeezed by force; the squeezing of the ball 10 pushes the sliding column 9 to start sliding into the connecting column 3, and at the same time changes the position of the sliding column 9, so that the inclination angle of the connecting rod 8 changes. This change will push the sliders 6 on both sides to slide on the column 5, and at the same time apply squeezing force to the spring 1 7; when the ball 1 0 reaches the reserved hole, the spring 7 pushes the connecting rod 8 to rotate through the reaction force, so that the sliding column 9 and the ball 10 slide outward. This process ensures that the ball 10 can be engaged in the corresponding reserved hole, and the protective shell 1 and the protective shell 1 or the protective shell 1 and the protective shell 2 are effectively connected; this design makes it possible to effectively protect the exposed wires according to needs, ensure the firmness and safety of the equipment connection, and achieve smooth and reliable docking process through the coordinated action of the ball 10, sliding column 9, connecting rod 8 and other components, providing convenience and guarantee for the use of the equipment.

[0033] Reference Figure 1 and Figure 4 , the protective shell 1 and the protective shell 2 are fitted together, the protective shell 1 is slidably connected to the limiting column 11 inside, one end of the ball 10 is fixedly connected to the limiting ring 12, the bottom of the limiting ring 12 is fitted with the protective shell 1, the other end of the spring 2 13 is fixedly connected to a block 14, the block 14 is fixedly connected to the other end of the limiting column 11, and one side of the block 14 is an arc-shaped opening;

[0034] Specifically, when the exposed wire is located in the protective shell 1, the block 14 is subjected to a force, pushing the limit column 11 to start sliding. This action causes the spring 13 to be squeezed, and the resulting reaction force is transmitted to the exposed wire position through the block 14, ensuring that exposed wires of different specifications and thicknesses can be easily fixed in the protective shell 1 to avoid large-scale shaking; this design ensures the stability and fixity of the exposed wire, allowing it to be safely stored and used in the protective shell 1. Through the coordinated action of the block 14, the limit column 11, the spring 13 and other components, the exposed wire position is reliably fixed, providing convenience and safety for the operation and maintenance of the equipment.

[0035] Working principle: when it is necessary to dock the equipment, the straight part only needs to dock the protective shells 1 with each other, and the curved part can dock a protective shell 2 2 between two protective shells 1. No matter docking the protective shell 1 or the protective shell 2 2, the corresponding connecting column 3 will be inserted into the connecting hole 4. At this time, the ball 10 will be squeezed by the force first, and then push the sliding column 9 so that the sliding column 9 starts to slide into the connecting column 3. At this time, the sliding column 9 changes the inclination angle of the connecting rod 8 while sliding, so that the connecting rod 8 can push the sliders 6 on both sides to slide on the column 5, and generate an extrusion force on the spring 1 7. When the ball 10 reaches the reserved hole, the corresponding spring 1 7 will be reversed. The generation of the force causes the connecting rod 8 to rotate at an inclined angle, thereby pushing the sliding column 9 and the ball 10 to slide outward, so that the ball 10 is engaged in the corresponding reserved hole, and the protective shell 1 is connected with the protective shell 1 and the protective shell 1 is connected with the protective shell 2. In this way, the corresponding exposed wire can be protected as needed, and when the corresponding exposed wire is in the protective shell 1, a force will be applied to the block 14, so that the limit column 11 starts to slide, and then the spring 2 13 is squeezed. The reaction force generated at this time will be transmitted to the exposed wire position through the block 14, so that the exposed wires of different specifications and thicknesses can be simply fixed in position in the protective shell 1 without causing large shaking.

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 substitutions for some of the technical features therein.
