Description

Technical Field

[0001] This utility model relates to the field of substation main transformer and reactor technology, specifically a base for an earthquake-resistant platform. Background Technology

[0002] In power systems, the main transformer (main transformer) and reactor in substations are core equipment, and their operational stability directly affects the safety of the power grid.

[0003] However, earthquakes are extremely destructive to substation equipment. Traditional installation methods have significant technical bottlenecks. Existing main transformers and reactors are usually directly fixed to concrete foundations and connected only by simple shims or bolts. They lack professional seismic design. When an earthquake occurs, the equipment is prone to violent shaking and displacement due to its large weight (the main transformer can weigh hundreds of tons) and high center of gravity, which can lead to winding deformation and bushing rupture. Therefore, there is an urgent need for a platform base with good seismic resistance. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a base for an anti-seismic platform, which solves the problem that the existing anti-seismic base has a slight shock absorption effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a base for an anti-seismic platform, comprising an upper base, a lower base, and bolt holes. The lower base is fixedly connected to the ground of the substation by bolts, and the upper base is fixedly connected to a reactor by bolts. Two grooves are provided on the opposite surfaces of the lower base and the upper base, and a shock-absorbing device is provided between the two bases.

[0008] The shock absorption device includes a rubber sheet, which is placed inside the groove. A connecting groove is formed on the outer surface of the rubber sheet, which penetrates the rubber sheet. The connecting groove is rectangular and has chamfered ends.

[0009] Preferably, a rubber block is placed between the upper base and the lower base, and a bolt group is slidably connected inside the rubber block, thereby fixing the rubber block to the upper base and the lower base through the bolt group.

[0010] Preferably, a metal cylinder is slidably connected inside the rubber sheet. The metal cylinder is hollow, and a spring is fixedly connected inside the metal cylinder.

[0011] Preferably, a metal block is fixedly connected to the upper end of the spring, and the metal block is slidably connected to the metal cylinder. When the metal cylinder is placed in the rubber plate, the top of the metal block is flush with the top of the rubber plate.

[0012] Preferably, the interior of the rubber block is hollow, the bottom wall of the rubber block is integrally formed with a rubber base plate, and a sheet metal is placed on the upper surface of the rubber base plate.

[0013] Preferably, the sheet metal is wavy, a silicone block is placed on the upper surface of the sheet metal, a rubber top plate is placed on the upper end of the silicone block, and the rubber top plate is in contact with the upper base.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a base for an earthquake-resistant platform, which has the following beneficial effects:

[0016] 1. When the silicone block moves downwards, it applies pressure to the sheet metal at the base of the anti-seismic platform. The wavy characteristics of the sheet metal allow it to accept the deformation and counteracting force of the silicone block. When the remaining impact force reaches the rubber base plate, it no longer has a high frequency of vibration. The use of this device can reduce the counteracting force, ensure the stability of the reactor, and increase its practicality.

[0017] 2. The base of this earthquake-resistant platform absorbs the downward impact of the spring under compression, thus offsetting most of the force. At the same time, the rubber block itself absorbs the force released after the spring is compressed. The rubber block is relatively large, which can offset the spring's recoil force, thus avoiding the spring's recoil force and increasing practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a new technical solution: a base for an anti-seismic platform, including an upper base 1, a lower base 2 and bolt holes 3. The lower base 2 is fixedly connected to the ground of the substation by bolts, and the upper base 1 is fixedly connected to the reactor by bolts. Two grooves 6 are opened on the opposite surfaces of the lower base 2 and the upper base 1. A shock-absorbing device is provided between the two bases. A rubber block 4 is placed between the upper base 1 and the lower base 2. A bolt group 5 is slidably connected inside the rubber block 4. The rubber block 4 is fixedly connected to the upper base 1 and the lower base 2 by the bolt group 5.

[0024] Furthermore, the shock absorption device includes a rubber plate 7, which is placed inside the groove 6. A connecting groove 8 is provided on the outer surface of the rubber plate 7, which penetrates the rubber plate 7. The connecting groove 8 is rectangular and has chamfered ends.

[0025] The rubber plate 7 has a metal cylinder 13 that is slidably connected inside. The metal cylinder 13 is hollow. A spring 14 is fixedly connected inside the metal cylinder 13. A metal block 15 is fixedly connected to the upper end of the spring 14. The metal block 15 is slidably connected to the metal cylinder 13. When the metal cylinder 13 is placed in the rubber plate 7, the metal block 15 is flush with the top of the rubber plate 7.

[0026] Furthermore, the interior of the rubber block 4 is hollow, and the bottom wall of the rubber block 4 is integrally formed with a rubber base plate 9. A sheet metal 10 is placed on the upper surface of the rubber base plate 9. The sheet metal 10 is wavy. A silicone block 11 is placed on the upper surface of the sheet metal 10. A rubber top plate 12 is placed on the upper end of the silicone block 11. The rubber top plate 12 is in contact with the upper base 1.

[0027] Furthermore, when using this device, it is first fixed according to the above connection relationship. When the device needs to be damped by force, the force generated by the reactor on the top is transmitted downward to the upper base 1. The impact force on the upper base 1 moves downward. The impact force on the upper base 1 is first absorbed by the rubber top plate 12, and then the remaining impact force enters the silicone block 11. Due to its own characteristics, the silicone block 11 absorbs part of the impact force. The force of the silicone block 11 continues to extend downward, and the silicone block 11 moves downward. When the silicone block 11 moves downward, it will apply pressure to the iron sheet 10. The wavy characteristics of the iron sheet 10 can accept the deformation counteracting force of the silicone block 11. At this time, when the remaining impact force reaches the rubber base plate 9, it no longer has a large vibration frequency. The use of this device can reduce the counteracting impact force, ensure the stability of the reactor, and increase practicality.

[0028] Furthermore, when using this device, the force generated by the reactor located above is transmitted downward to the upper base 1. At this time, some impact force comes into contact with the rubber plate 7, causing the connecting groove 8 in the rubber plate 7 to deform into an approximately elliptical shape, which can absorb the impact force. At the same time, the force received by the metal block 15 compresses the spring 14. The spring 14 is subjected to the force of compression and impacts downward, absorbing the force and offsetting most of the force. At this time, combined with the characteristics of the rubber block 4 itself, it can absorb the force released after the spring 14 is compressed. The rubber block 4 is relatively large, which can offset the recoil force of the spring 14, avoiding the recoil force of the spring 14 and increasing its practicality.

[0029] Structural Description:

[0030] Rubber block 4: Rubber block 4 has a certain elastic deformation ability, which can offset vibration.
