[0002] The shielding ring is a ring-shaped protective hardware that prevents other hardware or components within the shielded range from experiencing corona. It is generally made of bent aluminum round tubes. It reduces the electromagnetic radiation of the cable to the surrounding environment during transmission, thereby maintaining the working stability and reliability of the equipment.

[0003] Existing shielding ring assemblies, such as a new type of pressure-equalizing shielding ring proposed in patent application number "CN201720744553.7", are composed of a first aluminum tube, a second aluminum tube, a first support frame, and a second support frame. The first support frame is welded to the first aluminum tube, and the second support frame is welded to the second aluminum tube. The two groups of semicircular tubes are welded around the perimeter with argon arc welding, and the various connecting parts are connected by welding.

[0004] However, the existing technology has defects. The various connecting parts of the shielding ring are connected by welding. When a part of the shielding ring has a problem, it is inconvenient to replace the problem part. If the shielding ring is transported after welding and assembly, the assembled shielding ring occupies a large space and is inconvenient to transport. If it is transported before assembly, welding equipment is required during installation, and the installation conditions are relatively high. Therefore, a shielding ring assembly is proposed.

[0025] The following will be combined with the accompanying 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.

[0026] A shielding ring assembly, such as Figure 1-Figure 5 As shown, it includes a connecting ring 1 and a connecting ring 2, and the connecting ring 1 and the connecting ring 2 are plug-in connected. The interior of the connecting ring 1 and the connecting ring 2 is hollow, and the connecting ring 1 and the connecting ring 2 form an elliptical shielding ring with a larger protection area. The inner walls of the connecting ring 1 and the connecting ring 2 are fixed with two groups of side connecting plates 3, and the four groups of side connecting plates 3 are fixed with mounting feet 4 by bolts. The upper end of each group of mounting feet 4 is fixed with a connecting rod 6, and the upper ends of the two groups of connecting rods 6 on the same side are slidably connected with a bent rod 7. The upper ends of the two groups of bent rods 7 are fixed with a mounting plate 17. The two groups of mounting plates 17 are symmetrical to each other, and the two groups of mounting plates 17 are installed in coordination. The middle of the connecting ring 1 and the middle of the connecting ring 2 are fixed with support assemblies, and the ends of the two groups of support assemblies are indirectly fixed to the mounting plate 17.

[0027] By plugging connecting ring 1 and connecting ring 2, connecting rod 6 is installed on connecting ring 1 and connecting ring 2 through mounting foot 4, side connecting plate 3, and bolts. Two ends of a group of bent rods 7 connect the two groups of connecting rods 6. The bent rods 7 and the two groups of connecting rods 6 form a U shape, fixing and assembling one side of connecting ring 1 and connecting ring 2, and the other side of connecting ring 1 and connecting ring 2 have the same structure. When the two groups of bent rods 7 are installed through mounting plate 17, connecting ring 1 and connecting ring 2 are assembled. The structure adopts detachable type, which is convenient for disassembly and assembly, so as to facilitate the replacement of problem parts. It can be transported when not assembled, takes up little transportation space, is convenient for transportation, does not require welding equipment for installation, and has low installation conditions. Support components are set at both ends of the shielding ring. The support components prevent the two ends of the elliptical shielding ring from bending and damage due to various pressures, thereby increasing the structural stability of the shielding ring component.

[0028] like Figure 1 and Figure 3 As shown, a U-shaped frame 18 is fixed between the two groups of mounting plates 17, and both sides of the U-shaped frame 18 are respectively fitted with the two groups of mounting plates 17. A screw 19 is connected through the U-shaped frame 18, and both ends of the screw 19 pass through the two groups of mounting plates 17 respectively. Two groups of nuts 20 are threadedly connected to the screw 19, and the two groups of nuts 20 are tightly attached to the side of the mounting plate 17 away from the U-shaped frame 18.

[0029] A U-shaped frame 18 is sandwiched between the two sets of mounting plates 17 , and screws 19 and nuts 20 are used to install the U-shaped frame 18 and the mounting plates 17 .

[0030] like Figure 5 As shown, the connecting ring 1 and the connecting ring 2 are both set to be "U"-shaped, and holes 22 are opened at both ends of the connecting ring 1, and rods 21 are fixed at both ends of the connecting ring 2. The two groups of rods 21 are respectively plugged into the two groups of holes 22.

[0031] The connecting ring 1 and the connecting ring 2 are plugged and connected through the insertion hole 22 and the insertion rod 21 to prevent the ends of the connecting ring 1 and the connecting ring 2 from being misaligned.

[0032] like Figure 1-Figure 3 As shown, the support assembly includes a support plate 16, and one end of the two groups of support plates 16 is fixed with an end connecting plate 15 by bolts. The two groups of end connecting plates 15 are respectively fixed with connecting ring 1 and connecting ring 2 2, and the ends of the two groups of support plates 16 away from the end connecting plate 15 are respectively fixed with the two ends of the U-shaped frame 18.

[0033] One end of the support plate 16 is connected to the connecting ring 1 or the connecting ring 2 2, and the other end is connected to the U-shaped frame 18, thereby increasing the structural stability of the bending portion of the connecting ring 1 and the connecting ring 2 2.

[0034] like Figure 2 and Figure 4As shown, one end of the four groups of connecting rods 6 is fixedly connected to a sliding rod 12, and both ends of the two groups of bent rods 7 are provided with a sliding groove 10. The four groups of sliding rods 12 are respectively slidably connected to the four groups of sliding grooves 10. A return spring 13 is fixed between the end of the sliding rod 12 and the inner wall of the sliding groove 10. The return spring 13 is sleeved on the side wall of the sliding rod 12, and a damper 11 is fixed between the sliding rod 12 and the inner wall of the sliding groove 10.

[0035] When the shielding ring encounters strong winds, it causes wind vibration, and a pulling force is formed between the connecting rod 6 and the bent rod 7. The sliding rod 12 slides a certain distance in the sliding groove 10, and the degree of spring compression increases. The damper 11 prevents the sliding rod 12 from vibrating back and forth in the sliding groove 10, preventing the connecting rod 6 and the bent rod 7 from being damaged due to the large wind vibration energy. After the strong wind, the reset spring 13 pulls the two to reset.

[0036] like Figure 2 and Figure 4 As shown, the side wall of the end of the bent rod 7 is threadedly connected to a protective ring 9, one end of the protective ring 9 is sleeved on the connecting rod 6, and the side wall of the connecting rod 6 is located inside the protective ring 9 and is fixed with a sealing gasket 14 for preventing impurities from entering the protective ring 9.

[0037] The protective ring 9 prevents the side wall of the sliding rod 12 from being corroded due to rain or other reasons, which affects the sliding flexibility. The sealing gasket 14 increases the internal sealing of the sealing ring. The outer wall of the sealing ring fits and slides with the outside of the protective ring 9, which will not affect the displacement of the protective ring 9 relative to the connecting rod 6.

[0038] The working principle of a shielding ring assembly provided by the utility model is as follows:

[0039] By plugging connecting ring 1 and connecting ring 2, connecting rod 6 is installed on connecting ring 1 and connecting ring 2 through mounting foot 4, side connecting plate 3 and bolts. Bending rod 7 and two groups of connecting rods 6 form a U shape, and connecting ring 1 and connecting ring 2 are fixedly assembled. When two groups of bending rods 7 are installed through mounting plate 17, connecting ring 1 and connecting ring 2 are assembled. The structure adopts a detachable type, which is convenient for disassembly and assembly, so as to facilitate the replacement of problem parts. It can be transported when not assembled, takes up little transportation space, is convenient for transportation, does not require welding equipment for installation, and has low installation conditions. Support components are set at both ends of the shielding ring. The support components prevent the two ends of the elliptical shielding ring from bending and damage due to various pressures, thereby increasing the structural stability of the shielding ring assembly.
