[0035] like Figures 1 to 5 As shown, this application provides a protective device, including a mounting base 10 and a protective structure 20. The mounting base 10 has multiple limiting structures 11, and is provided with fixing holes 12 and multiple insertion holes 13. The multiple insertion holes 13 are arranged one-to-one with the multiple limiting structures 11, and the multiple insertion holes 13 and the multiple limiting structures 11 are spaced apart around the outer periphery of the fixing holes 12. The mounting base 10 is used for fixed installation. The protective structure 20 has a protective plate 21 and multiple connectors 22 that are interconnected. The multiple connectors 22 are located on the same side of the protective plate 21, and are arranged one-to-one with the multiple insertion holes 13. The protective plate 21 is located inside the fixing holes 12. The connectors 22 are provided with connecting holes 2221. Insertion pieces 30 are inserted into the connecting holes 2221 and the corresponding insertion holes 13. The insertion pieces 30 and the limiting structures 11 cooperate to limit the circumferential rotation of the protective structure 20 relative to the mounting base 10 and limit the axial displacement of the mounting base 10.

[0036] Using the technical solution of this application, the protective structure 20 is mounted on the mounting base 10, and the protective plate 21 is located within the fixing hole 12 to protect the battery. Multiple connectors 22 and multiple insertion holes 13 are correspondingly arranged, and the insertion pieces 30 pass through the connection holes 2221 and insertion holes 13. The insertion pieces 30 and the limiting structure 11 cooperate to restrict the position of the protective structure 20 relative to the mounting base 10. With this arrangement, through the cooperation of the insertion pieces 30 with the connection holes 2221 and insertion holes 13, and with the assistance of the limiting structure 11, the protective structure 20 can be quickly installed and disassembled, greatly reducing maintenance and replacement time and improving work efficiency. The cooperation between the insertion pieces 30 and the limiting structure 11 ensures the stability and reliability of the protective structure 20 during use, preventing loosening due to vibration or external force. The protective plate 21, located within the fixing hole 12, effectively prevents external impurities from entering the fixing hole 12, protecting internal components from contamination or damage. Furthermore, by adopting the above structure, the protective structure 20 can be deeply cleaned online, ensuring that no dust falls into the winding core, while improving equipment uptime and output.

[0037] In this application, the mounting base 10 is fixed on the rotating platform, and only the protective structure 20 needs to be removed and installed.

[0038] like Figure 1 and Figure 5 As shown, the connector 22 is mounted on the mounting base 10, and the plug-in component 30 includes a plug-in rod 31 and a limiting block 32 connected to each other. The plug-in rod 31 passes through the corresponding connecting hole 2221 and plug-in hole 13, and the limiting block 32 abuts against the connector 22. This configuration, with the plug-in rod 31 engaging with the connecting hole 2221 and plug-in hole 13, combined with the abutment of the limiting block 32 against the connector 22, simplifies and speeds up the installation and disassembly process, significantly reducing the time required for maintenance and replacement, and improving the equipment's operating efficiency and productivity. Furthermore, this structure prevents the plug-in rod 31 from falling out of the connecting hole 2221 and plug-in hole 13, thus ensuring the normal operation of the protective structure 20.

[0039] like Figure 3 As shown, the connector 22 includes a connecting plate 221 and a fixing plate 222. One end of the connecting plate 221 is fixedly connected to the protective plate 21. One end of the fixing plate 222 is fixedly connected to the other end of the connecting plate 221. The fixing plate 222 is provided with a connecting hole 2221, and the fixing plate 222 overlaps with the mounting base 10. This configuration, combined with the connecting plate 221, provides a more stable connection. The connecting hole 2221 on the fixing plate 222 mates with the insertion hole 13 on the mounting base 10, and is locked in place by the insertion piece 30, ensuring the robustness of the protective device under various working conditions. Furthermore, the connector 22 has a simple structure, making it easy for workers to process.

[0040] like Figure 2 As shown, the limiting structure 11 has a slot 111, and one side of the fixing plate 222 abuts against the side wall of the slot 111. This arrangement ensures that the fixing plate 222 is precisely aligned during installation, preventing it from sliding laterally or longitudinally, thus ensuring the stability and positioning accuracy of the protective structure 20. The side wall abutment design of the slot 111 simplifies the installation and disassembly process of the fixing plate 222. During disassembly, simply slide the fixing plate 222 out of the slot 111; during installation, simply slide one side of the fixing plate 222 into the slot 111, achieving quick and convenient assembly and disassembly.

[0041] like Figure 3 As shown, the connecting hole 2221 has an opening on the side away from the limiting structure 11. This opening design allows the connector 30 to be easily inserted into the connecting hole 2221 during installation without the need for precise alignment or additional force, thus simplifying the installation process and improving work efficiency.

[0042] like Figure 4 As shown, the protective plate 21 is provided with a fixing groove 211, and one end of the connecting plate 221 is disposed in the fixing groove 211. With this arrangement, the cooperation between the fixing groove 211 and the connecting plate 221 can ensure that the connecting plate 221 is firmly fixed on the protective plate 21, reducing loosening caused by vibration or external force, and improving the stability and reliability of the overall structure.

[0043] like Figure 1 As shown, the mounting base 10 has an annular protrusion 14 surrounding the outer periphery of the fixing hole 12. Multiple insertion holes 13 and multiple limiting structures 11 are annularly spaced on the annular protrusion 14. This arrangement improves the structural strength of the mounting base 10 and prevents damage to the mounting base 10 caused by the insertion holes 13 and limiting structures 11, thereby extending the service life of the mounting base 10.

[0044] like Figure 4 As shown, the protective plate 21 has a clearance groove 212 on the side opposite to the connector 22, and the clearance groove 212 is located between the center of the connector 22 and the protective plate 21. With this configuration, the clearance groove 212 can effectively optimize the layout inside or around the equipment, provide the necessary space for other components or pipes, avoid mutual interference, and make the entire system design more compact and reasonable.

[0045] The clearance groove 212 is formed by stamping. This design utilizes stamping, a high-speed metal processing method, to produce a large number of identical or similar parts in a short time. Forming the clearance groove 212 onto the metal sheet in a single operation using a mold significantly improves production efficiency and shortens the manufacturing cycle. Stamping typically produces a smoother surface, which helps reduce dust and welding slag accumulation inside the clearance groove 212, facilitating cleaning and maintenance. It also improves the product's appearance and extends its service life.

[0046] With this configuration, during the stamping process, a groove is formed on one side of the protective plate 21, and a protrusion is formed on the other side of the protective plate 21.

[0047] Specifically, the connecting plate 221 is welded to the fixing groove 211. This arrangement provides a permanent connection; by directly welding the connecting plate 221 to the fixing groove 211, it offers extremely high structural stability, ensuring that the connection will not loosen or detach under heavy loads or vibrations. Welding not only strengthens the connection between the connecting plate 221 and the fixing groove 211 but also increases the rigidity of the overall structure, reduces deformation or damage caused by external forces, and extends the service life of the components.

[0048] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0049] 1. By designing a plug-in protection device, the cleaning operation time of a single station is shortened to less than 1 minute, and the total operation time of a single machine is controlled within 4 minutes, which greatly improves the efficiency of cleaning and maintenance and reduces the non-productive downtime of the equipment.

[0050] 2. Traditional screw fixing methods are prone to damage during repeated disassembly and assembly, resulting in high maintenance costs. The protective device of this invention uses a plug-in connector 30 and a rotation fixing method, reducing component wear and replacement frequency, and effectively lowering long-term maintenance costs.

[0051] 3. The adoption of the above-mentioned protective devices reduces cleaning and parts replacement time, improves equipment availability, and thus enhances the overall equipment uptime. Increased equipment uptime directly translates into increased production, thereby improving the company's output and economic benefits.

[0052] 4. The protective device is easy to operate, learn and master, reducing the need for technical training for operators, lowering the company's human resource costs, and improving the safety and accuracy of operations.

[0053] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0055] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
