The upper end of the swing link 9 is rotatably provided with a fixed shaft 23.

In this embodiment, the gravity block 131 is provided with a through hole penetrating through the left and right sides, the inertia pin 16 is slidably disposed in the through hole, the left and right sides of the through hole are provided with round chamfers to form a round surface 28, and the length of the return spring 17 is greater than that of the limiting hole.

In this embodiment, the auxiliary mounting assembly further comprises a mounting plate 26, a slide bar 25 and a ground pile 3. Mounting plate 26 sets up in the lower terminal surface of pendulum rod 9, and the upper end of slide bar 25 sets up in the lower surface of mounting plate 26, and ground stake 3 can set up in slide bar 25 and upper end detachably sets up in mounting plate 26 with sliding from top to bottom.

In this embodiment, ground shell 19 sets up in ground 18, puts into ground shell 19 a plurality of ground piles 3 that need install again, and ground pile 3 has preset distance with ground 18, pours into concrete 20 afterwards and plays the fixed action to a plurality of ground piles 3, and mounting plate 21 sets up in the top of a plurality of ground piles 3, and box 24 sets up on mounting plate 21.

The assembly work process of the new generation of internet box type substation in the embodiment is as follows:

after the auxiliary mounting assembly is mounted in place on the ground 18, the ground pile 3 is moved along the side of the slide bar 25 adjacent to the mounting plate 26, and after the auxiliary mounting assembly is moved into place, the ground pile 3 is fixedly connected to the mounting plate 26.

After the connecting rod 13 and the gravity block 131 are manually shifted upwards to enable the limiting hole to be coaxial with the through hole, one end, close to the gravity block 131, of the reset spring 17 extends outwards under the elastic action of the reset spring and enters the through hole in the gravity block 131 for a certain distance.

The gravity block 131 is fixed manually, the gravity block is prevented from being ejected out by the ejection spring 15, meanwhile, the swing rod 9 is pulled to rotate anticlockwise for a certain distance around the fixed shaft 23, after the gravity block stays for a preset time, two hands are simultaneously loosened, at the moment, the inertia pin 16 compresses the return spring 17 on one side under the action of gravity and simultaneously enters the limiting hole, and the gravity block 131 is locked at the position of the limiting hole by the inertia pin 16 in a clamping mode.

When the swing rod 9 and the gravity block 131 are loosened, the swing rod 9 can deflect left and right back and forth around the fixed shaft 23, as shown in fig. 12, the swing rod moves from the position a to the position B, then moves from the position B to the position C, and gradually approaches to be vertical under the action of gravity, in the process, due to the action of inertia, the inertia pin 16 can slide back and forth in the through hole and the two limiting holes, as shown in fig. 11, E, F and D are motion tracks of the inertia pin 16.

When the inertia pin 16 moves to the middle position of the gravity block 131, at this time, the inertia pin 16 does not lock the gravity block 131, but the end of the return spring 17 is still in the through hole on the gravity block 131, and the end of the return spring 17 locks the gravity block 131, of course, the gravity block 131 also causes the return spring 17 to compress and deform, but this process requires a certain time, and during this time, the inertia pin 16 already extends outwards under the action of inertia to enter the limiting hole, so that the gravity block 131 is locked in the whole swing process of the swing link 9 through the cooperation of the return spring 17 and the inertia pin 16.

After the swing rod 9 stops swinging, the inertia force of the inertia pin 16 disappears, the gravity block 131 moves downwards under the continuous action of the pop-up spring 15 to enable the return springs 17 on the two sides to be separated from the through hole, at the moment, the gravity block 131 pops downwards and strikes the bottom wall of the notch, the swing rod 9 vibrates, positive pressure of the swing rod 9 on the fixed shaft 23 is reduced at a certain moment, and therefore friction force between the swing rod 9 and the fixed shaft 23 is reduced, and the vertical degree of the swing rod 9 is enabled to be larger.

Meanwhile, after the gravity block 131 falls, as the acting point of the cotton thread 11 on the gravity block 131 moves downwards, the vertical distance from the acting force of the cotton thread 11 on the gravity block 131 to the fixed shaft 23 is lengthened, that is, the arm of force is lengthened, so that the moment for the cotton thread 11 to push the gravity block 131 to rotate is increased, the swing rod 9 further approaches to a vertical state, and then the tightening bolt 8 is rotated to limit the rotation of the swing rod 9. Then the ground piles 3 on the mounting plate 26 are disassembled to enable the ground piles 3 to descend into the foundation shell 19, the ground piles 3 are sequentially installed, then concrete 20 is poured to fix the ground piles 3, the mounting bottom plate 21 is arranged at the tops of the ground piles 3, and the box body 24 is mounted on the mounting bottom plate 21.

In other embodiments, as shown in fig. 14, a cavity is formed inside the inertia pin 16, a circular heavy ball is disposed in the cavity, the heavy ball slides back and forth in the cavity along with the swinging of the inertia pin 16, and the heavy ball converts the gravitational potential energy of the heavy ball into kinetic energy and transmits the kinetic energy to the inertia pin 16 to increase the inertia force of the inertia pin 16.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
