[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 As shown, an earthquake-resistant box-type substation of an embodiment of the utility model includes an installation box 1, on the inner side of which is movably installed a box-type substation body 10 extending to the top thereof, two support plates 2 are correspondingly arranged at the front and rear of the lower surface of the box-type substation body 10, two shock absorbers 20 are arranged between the left and right ends of the support plate 2 and the inner bottom wall of the installation box 1, and a shock-absorbing mechanism is also arranged between the middle part of the support plate 2 and the inner bottom wall of the installation box 1.

[0020] When in use, there are two support plates 2 and they are fixedly mounted on the lower surface of the box-type substation body 10 in front and back correspondence. Four shock absorbers 20 are correspondingly arranged on the two support plates 2. The four shock absorbers 20 are distributed at the four corners below the box-type substation body 10. The shock absorber 20 can provide buffering for the vibration of the box-type substation body 10, and the damping characteristics of the shock absorber 20 can suppress the rebound of the box-type substation body 10 and thus ensure the seismic performance of the box-type substation body 10; by setting a shock-absorbing mechanism, a further shock-absorbing effect is provided for the box-type substation body 10, thereby ensuring the seismic effect of the box-type substation body 10.

[0021] The shock-absorbing mechanism includes a slide bar 3 fixed to the inner bottom wall of the installation box 1, and two sliding members 30 are correspondingly arranged on the left and right sides of the slide bar 3. The two sliding members 30 are movably connected to the support plate 2 through a connecting rod assembly, and a shock-absorbing spring 31 is also arranged outside the slide bar 3 between the two sliding members 30; the connecting rod assembly includes a U-shaped seat 4, a connecting seat 40 and a linkage arm 41, the U-shaped seat 4 is fixed to the lower surface of the support plate 2, the connecting seat 40 is molded on the upper surface of the sliding member 30, and the two ends of the linkage arm 41 are respectively hinged to the U-shaped seat 4 and the connecting seat 40.

[0022] When in use, when the box-type substation body 10 is vibrated, the vibration is transmitted to the two U-shaped seats 4 at the lower end through itself, and then transmitted to the two linkage arms 41 by the U-shaped seats 4. The linkage arms 41 drive the two sliding members 30 to move toward each other along the sliding rod 3 (fixed to the inner bottom wall of the installation box 1 through two supporting seats) by pushing. The two sliding members 30 move toward each other along the sliding rod 3 to convert the vibration of the box-type substation body 10 into the pressure applied by the two sliding members 30 to the shock absorbing spring 31. The shock absorbing spring 31 converts the pressure into its own elastic force to resist the pressure of the two sliding members 30, thereby achieving the shock absorbing effect.

[0023] The sliding member 30 includes a first sliding sleeve portion 32 and a second sliding sleeve portion 33. The connecting seat 40 is located on the upper surface of the first sliding sleeve portion 32. The outer ring of the second sliding sleeve portion 33 is provided with a sleeve 5. The sleeve 5 includes a sleeve 50 and a sliding portion 51. The two ends of the shock-absorbing spring 31 are respectively abutted against the two sleeves 50. The sliding portion 51 is provided with a plurality of positioning grooves 52 at equal distances and intervals. The depth of each positioning groove 52 is arranged from shallow to deep. A limit clamp 53 is fixed on the outer surface of the second sliding sleeve portion 33.

[0024] When in use, the matching stability between the two sliding members 30 and the shock absorbing spring 31 is ensured by providing the abutment sleeve 5;

[0025] In the initial state, the relative position of the sleeve 5 and the second sleeve part 33 is limited by the limiting clamping between one of the positioning grooves 52 on the sliding part 51 and the limiting clamping head 53 on the outer surface of the second sleeve part 33. When the shock-absorbing spring 31 is fatigued (the shock-absorbing strength is reduced) due to long-term use, or the shock-absorbing strength of the shock-absorbing spring 31 needs to be enhanced, the sleeve 5 is slid until the limiting clamping head 53 exits the current positioning groove 52, and the sleeve 5 is rotated to clamp the clamping head with the shallower positioning groove 52 to limit the sleeve 5 again. At this time, the initial spacing between the two sleeves 5 is reduced, thereby ensuring the shock-absorbing effect of the shock-absorbing spring 31; when the shock-absorbing feedback of the shock-absorbing spring 31 needs to be reduced, the sleeve 5 is rotated to switch the clamping head to clamp with the deeper positioning groove 52. At this time, the initial spacing between the two sleeves 5 is increased, and the adjustment is completed.

[0026] An accommodating recess 34 is formed at the outer open end of the first sleeve portion 32 . A lubricating sleeve 35 is built in the accommodating recess 34 . A plurality of oil injection holes 36 are formed on the outer surface of the first sleeve portion 32 at positions corresponding to the accommodating recess 34 .

[0027] When in use, the lubricating sleeve 35 is preferably made of an oil-absorbing sponge material. During daily use, the lubricating oil is injected into the oil filling hole 36 and the lubricating oil is absorbed by the lubricating sleeve 35. When the first sliding sleeve portion 32 slides along the sliding rod 3, the oil in the lubricating sleeve 35 is squeezed and distributed on the surface of the sliding rod 3. The lubricating oil provides lubrication for the sliding of the sliding part 30, further improving the sliding smoothness of the sliding part 30.

[0028] The inner walls on the left and right sides of the installation box 1 are fixedly connected with slide rails 11 , and the left and right sides of the box-type substation body 10 are provided with two slide seats 12 adapted to the slide rails 11 .

[0029] During use, due to the arrangement of the slide rail 11 and the slide seat 12, the box-type substation body 10 can only move up and down when subjected to vibration or strong wind impact, thereby preventing the box-type substation body 10 from shaking left and right, causing the internal electrical equipment to shake significantly and be damaged.

[0030] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
