[0002] As a common connecting component in building structure, the sealing performance of bushing through wall is crucial to prevent the leakage of water, gas or other substances. Most of the existing sealing rings of bushing through wall have a single structure, and the sealing effect is limited. In the long-term operation process, affected by environmental factors (such as temperature change, humidity fluctuation) and mechanical vibration, the sealing ring is prone to aging, deformation and loosening, etc. problems, leading to sealing failure, and then the moisture, dust and other impurities outside enter the inside of the bushing through wall, affecting the insulation performance of electrical equipment, increasing the risk of equipment failure. At the same time, the traditional sealing ring has insufficient anti-seismic ability, and under the action of vibration generated by earthquake, equipment start-stop, etc. it is difficult to effectively buffer and absorb vibration energy, which may cause loosening of the connecting part of the bushing through wall, and even cause damage to the sleeve, seriously threatening the safe and stable operation of the power system.

[0028] Further, the limit inner ring 11 is embedded on the inner walls of the two ends of the wall bushing 10, so that there are fixed support points on the inner walls of the two ends of the wall bushing 10, which can limit the axial movement of the composite sealing ring structure 20 in the wall bushing 10, ensuring the stability and sealing effect of the sealing ring structure, the flanges 12 are symmetrically arranged at the two ends of the wall bushing 10, so that the two ends of the wall bushing 10 can be conveniently connected with other pipelines or equipment, and the flanges 12 also provide additional structural strength to enhance the overall stability of the wall bushing.

[0029] It is worth noting that the outer diameters of the inner ring seat 21, the first anti-vibration ring 22 and the second anti-vibration ring 23 are adapted to and plug-in fitted with the inner diameter size of the wall bushing 10, ensuring that these components can be tightly installed in the wall bushing 10, not only improving the convenience of installation, but also maximizing the sealing and anti-vibration effect.

[0030] Among them, the end of the sealing compression ring seat 30 is provided with a sealing compression head 31 which is adapted to and plug-in fitted with the inner diameter size of the wall bushing 10, so that the sealing compression ring seat 30 can be tightly pressed on the composite sealing ring structure 20, further enhancing the sealing effect. At the same time, the sealing compression head 31 is adapted to the inner diameter size of the wall bushing 10, also ensuring the stability of the installation.

[0031] It is worth noting that the sealing head 31 and the composite sealing ring structure 20 are in close contact to ensure the maximum sealing effect, prevent external substances from entering the inside of the through-wall sleeve through the gap, and improve the safety of the entire system.

[0032] Specifically, the sealing compression ring seat 30 has the same diameter as the flange 12, and the sealing compression ring seat 30 is connected to the flange 12 by at least three sets of locking bolts 32. This not only ensures a tight connection between the sealing compression ring seat 30 and the flange 12, but also improves the stability and reliability of the connection, preventing seal failure due to loosening.

[0033] Furthermore, the first sealing ring 212 and the second sealing ring 213 are made of rubber with a thickness of 2-5mm. Rubber sealing rings possess excellent elasticity and sealing performance, enabling them to meet sealing requirements under various complex working conditions. Simultaneously, the 2-5mm thickness ensures sealing effectiveness while avoiding installation difficulties caused by excessive thickness. This design not only improves sealing reliability but also extends the service life of the sealing rings.

[0034] Working principle of the seismic-resistant composite sealing ring assembly of this through-wall bushing:

[0035] First, prepare the through-wall sleeve 10, with limiting inner rings 11 embedded in the inner walls at both ends and flanges 12 at both ends;

[0036] Next, the composite sealing ring structure 20 is installed. The inner ring seat 21, the first anti-vibration ring 22, and the second anti-vibration ring 23 are assembled in sequence. The insertion grooves 24 on both sides of the inner ring seat 21 are inserted into the insertion joints 25 on the first anti-vibration ring 22 and the second anti-vibration ring 23 to complete the splicing of the sealing ring structure. Since the outer diameters of the inner ring seat 21, the first anti-vibration ring 22, and the second anti-vibration ring 23 are all compatible with the inner diameter of the through-wall sleeve 10, the assembled composite sealing ring structure 20 is inserted into the through-wall sleeve 10, and the limiting inner ring 11 can position it.

[0037] Then install the sealing compression ring seat 30, whose end sealing head 31 is adapted to the inner diameter of the through-wall sleeve 10. Place the sealing compression ring seat 30 close to the end of the through-wall sleeve 10 so that the sealing head 31 is in close contact with the composite sealing ring structure 20. Since the sealing compression ring seat 30 has the same diameter as the flange 12, use at least three sets of locking bolts 32 to connect the sealing compression ring seat 30 to the flange 12. Tighten the bolts so that the sealing compression ring seat 30 applies pressure to the composite sealing ring structure 20 to ensure the sealing effect. During operation, the cooperation of various structures can achieve good sealing and seismic resistance.
