[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-7 As shown, a shielding cover for high-voltage power transmission equipment includes a first shielding ring 1, a second shielding ring 2, a third shielding ring 3, a top shielding cover 4 and a bottom fixing ring 5. The first shielding ring 1, the second shielding ring 2 and the third shielding ring 3 are arranged in order from bottom to top, the top shielding cover 4 is fixed to the upper side of the inside of the third shielding ring 3, the bottom fixing ring 5 is fixed to the lower side of the inside of the first shielding ring 1, and a workpiece mounting hole 7 is opened in the middle position of the bottom fixing ring 5. When installing the shielding cover, the workpiece enters the inside of the shielding cover through the workpiece mounting hole 7. A plurality of nail holes 6 are also opened on the bottom fixing ring 5 for fixing the shielding cover with screws.

[0038] See also Figure 2-4 As shown, the upper sides of the first shielding ring 1 and the second shielding ring 2 are fixedly connected with a connecting inner ring 8, and the lower sides of the second shielding ring 2 and the third shielding ring 3 are fixedly connected with a connecting outer ring 9, and the connecting outer ring 9 can be snapped onto the outer side of the connecting inner ring 8. The first shielding ring 1 and the second shielding ring 2 as well as the second shielding ring 2 and the third shielding ring 3 are connected via the connecting inner ring 8 and the connecting outer ring 9. At this time, the preliminary connection between the first shielding ring 1 and the second shielding ring 2 as well as the second shielding ring 2 and the third shielding ring 3 can be completed by placing the connecting outer ring 9 on the outer side of the connecting inner ring 8;

[0039] A plurality of reinforcement components are fixedly connected to the inner walls of the first shielding ring 1 and the second shielding ring 2 to improve the stability of the connection between the first shielding ring 1 and the second shielding ring 2 and the second shielding ring 2 and the third shielding ring 3;

[0040] See also Figure 2 and Figure 3-4 The reinforcement component includes a rotating bracket 10, a reinforcement plate and a magnetic adjustment component. The rotating bracket 10 is fixed to the upper side of the inner wall of the second shielding ring 2 or the third shielding ring 3. The reinforcement plate is rotatably connected to the rotating bracket 10. The magnetic adjustment component is used to adjust the angle of the reinforcement plate.

[0041] At this time, when the shielding cover is assembled, the angle of the reinforcing pressure plate is adjusted through the magnetic adjustment component to make the reinforcing pressure plate and the inner wall of the shielding ring abut against or separate. When the reinforcing pressure plate and the inner wall of the shielding ring abut against each other, the connection of the shielding ring is relatively firm. When the reinforcing pressure plate and the inner wall of the shielding ring are separated, the shielding ring can be quickly disassembled.

[0042] Among them, see Figure 4-6 As shown, the reinforcement platen includes a first platen 11 and a second platen 15. The second platen 15 is tilted and fixed on the lower side of the first platen 11, and the lower end of the second platen 15 is tilted toward the direction close to the rotating bracket 10. The tilt angle is preferably 30 to 50 degrees. The inclination of the second platen 15 can effectively reduce the working space required for the reinforcement assembly, thereby greatly reducing the volume of the device.

[0043] In order to make the first shielding ring 1 and the second shielding ring 2 as well as the second shielding ring 2 and the third shielding ring 3 connected more tightly when the reinforcing pressure plate presses the shielding ring, a pressing plate 12 is fixedly connected to the upper side of the first pressure plate 11 close to the rotating bracket 10, and the lower sides of the inner walls of the second shielding ring 2 and the third shielding ring 3 are provided with a plurality of matching grooves 14 adapted to the pressing plate 12, and the cross-section of the matching groove 14 is an inverted right triangle. At this time, when the pressing plate 12 presses the inner wall of the matching groove 14, the horizontal force is converted into a downward force through the matching groove 14, so that the second shielding ring 2 and the third shielding ring 3 move downward.

[0044] At the same time, in order to reduce the friction between the pressing plate 12 and the matching groove 14, a rotating ring 13 is rotatably connected to the pressing plate 12. The rotating ring 13 can effectively reduce the wear of the pressing plate 12 sliding inside the matching groove 14.

[0045] In order to specifically describe the magnetic force adjustment component, the specific structure of a magnetic force adjustment component is described herein. The magnetic force adjustment component includes a limiting slide rail 18 fixed on the inner wall of the first shielding ring 1 or the second shielding ring 2 and a sliding cavity 16 opened on the second pressure plate 15. A sliding seat 17 is slidably connected inside the sliding cavity 16. The sliding seat 17 is rotatably connected to a sliding connection member 22 on one side close to the limiting slide rail 18. One end of the sliding connection member 22 close to the limiting slide rail 18 is slidably connected to the inside of the limiting slide rail 18. Both sides of the sliding connection member 22 are fixedly connected with an L-shaped connecting rod 23. The connecting rod 23 is fixedly connected to a second magnet 24 that fits the inner wall of the second shielding ring 2 or the third shielding ring 3 on the side away from the sliding connection member 22.

[0046] See also Figure 1-2 and Figure 7 As shown, the magnetic adjustment component is also equipped with a magnetic power plate to provide kinetic energy for the magnetic adjustment component;

[0047] The magnetic power board includes a hand grip board 20, to which a first magnet 21 is fixedly connected, and the first magnet 21 and the second magnet 24 are magnetically attracted to each other;

[0048] At this time, when the angle of the first pressure plate 11 needs to be adjusted, the position of the first magnet 21 is adjusted by moving the hand-grip plate 20, so that the first magnet 21 and the second magnet 24 are magnetically attracted to each other, and then the first magnet 21 is driven to move vertically on the outside of the shielding ring. When the first magnet 21 moves, it will drive the second magnet 24 to move together. When the second magnet 24 moves, it will drive the sliding connector 22 to move together through the connecting rod 23. When the sliding connector 22 moves, it will slide inside the sliding cavity 16 through the sliding seat 17. Because the second pressure plate 15 is tilted, when the sliding seat 17 slides inside the sliding cavity 16, it will drive the second pressure plate 15 to rotate, thereby adjusting the angle of the first pressure plate 11.

[0049] Moreover, in order to more conveniently position the first shielding ring 1 and the second shielding ring 2 as well as the second shielding ring 2 and the third shielding ring 3 and avoid the displacement of the rotating ring 13 and the matching groove 14, a stop guide groove 26 is opened on the outer side of the inner ring 8, and a stop guide strip 25 is fixedly connected to the inner side of the outer ring 9. The stop guide strip 25 is clamped in the inside of the stop guide groove 26, and the cross-sectional shape of the stop guide groove 26 and the stop guide strip 25 is preferably an inverted isosceles triangle. At this time, when the first shielding ring 1 and the second shielding ring 2 or the second shielding ring 2 and the third shielding ring 3 are spliced, the stop guide strip 25 is clamped into the inside of the stop guide groove 26, so as to complete the positioning of the first shielding ring 1 and the second shielding ring 2 as well as the second shielding ring 2 and the third shielding ring 3.

[0050] Likewise, see Figure 1-2As shown, because the second shielding ring 2 is opaque, the position of the second magnet 24 cannot be observed from the outside of the shielding ring. In order to allow the user to more accurately determine the area outside the shielding ring corresponding to the second magnet 24, the outsides of the first shielding ring 1 and the second shielding ring 2 are provided with prompt marks 19 suitable for the second magnet 24. By observing the prompt marks 19, the approximate position of the second magnet 24 can be known.

[0051] When in use: the workpiece then enters the interior of the shielding cover through the workpiece mounting hole 7, and then the shielding cover is fixed by screws, thereby completing the fixing of the first shielding ring 1;

[0052] Then, the second shielding ring 2 is placed on the upper side of the first shielding ring 1. At this time, the anti-rotation guide strip 25 is inserted into the anti-rotation guide groove 26, so that the first shielding ring 1 and the second shielding ring 2 can be connected. At the same time, the inner ring 8 and the outer ring 9 are connected to complete the preliminary connection of the first shielding ring 1 and the second shielding ring 2.

[0053] Then, the position of the first magnet 21 is adjusted by moving the hand grip plate 20 downward, so that the first magnet 21 and the second magnet 24 are attracted to each other by magnetic force, and then the first magnet 21 is driven to move vertically outside the shielding ring. When the first magnet 21 moves, it will drive the second magnet 24 to move together. When the second magnet 24 moves, it will drive the sliding connector 22 to move together through the connecting rod 23. When the sliding connector 22 moves, it will slide inside the sliding cavity 16 through the sliding seat 17. Because the second pressing plate 15 is tilted, when When the sliding seat 17 slides inside the sliding cavity 16, it drives the second pressing plate 15 to rotate, thereby adjusting the angle of the first pressing plate 11, and allowing the first pressing plate 11 to drive the pressing plate 12 to rotate toward the matching groove 14 until the pressing plate 12 and the inner wall of the matching groove 14 abut against each other. At this time, the force applied by the pressing plate 12 to the second shielding ring 2 is converted into a force driving the second shielding ring 2 downward through the matching groove 14, so that the second shielding ring 2 moves downward, thereby completing the reinforcement of the first shielding ring 1 and the second shielding ring 2;

[0054] Then, the third shielding ring 3 is assembled on the upper side of the second shielding ring 2, and the magnetic power plate is slid downward on the outer side of the second shielding ring 2 to adjust the position of the second magnet 24 inside the second shielding ring 2, so that the angle of the corresponding first pressing plate 11 can be adjusted until the pressing plate 12 and the inner wall of the matching groove 14 are abutted against each other, thereby reinforcing the second shielding ring 2 and the third shielding ring 3;

[0055] When disassembling the device, place the magnetic power plate outside the corresponding shielding ring again, then slide the magnetic power plate upward to drive the corresponding second magnet 24 to slide, so that the first pressing plate 11 moves away from the shielding ring, so that the pressing plate 12 and the matching groove 14 are separated, and the corresponding shielding ring can be directly disassembled;

[0056] In summary, the present invention can control the reinforcement components inside the shielding cover by magnetic force on the outside of the shielding cover by setting a magnetic power plate, thereby fixing the shielding cover and effectively reducing the gap after the shielding cover is assembled, thereby greatly improving the shielding performance of the shielding cover;

[0057] At the same time, the separation of the first shielding ring 1, the second shielding ring 2 and the third shielding ring 3 can greatly reduce the space required for the transportation and storage of the device, providing great convenience for the transportation and storage of the device;

[0058] By providing the pressing plate 12 and the matching groove 14, when the first pressing plate 11 squeezes the second shielding ring 2 or the third shielding ring 3, the second shielding ring 2 or the third shielding ring 3 can be driven to move downward, thereby improving the tightness of the connection between the first shielding ring 1 and the second shielding ring 2 and the second shielding ring 2 and the third shielding ring 3.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
