[0025] like Figures 1 to 4 As shown, an embodiment of the present invention discloses a seismic simulation test device, which is used to simulate the situation where various shock waves are applied to an electrical cabinet device 100, and the device includes: a shear wave simulation unit 10, a longitudinal wave simulation unit 20, and a composite wave simulation unit 30.

The first locking mechanism 14 includes a first rotating rod 141 pivotally connected to the transverse wave base 11, a first ear plate 142 installed on the transverse wave movable frame 12 and used for receiving the end of the first rotating rod 141, and a first pin shaft 143 used to penetrate the first ear plate 142 and the end of the first rotating rod 141. In this way, the first ear plate 142 and the first rotating rod 141 can be penetrated by the first pin shaft 143 to fix the transverse wave movable frame 12 to the transverse wave base 11 by means of the first rotating rod 141. At this time, the first locking mechanism 14 is in a locked state, and the restriction on the transverse wave movable frame 12 can be released by withdrawing the first pin shaft 143 from the first ear plate 142 and the first rotating rod 141 and rotating the first rotating rod 141 away, so that the transverse wave movable frame 12 can move back and forth relative to the transverse wave base 11.

The electrical cabinet equipment 100 to be simulated is fixed on the longitudinal wave movable frame 22; the longitudinal wave movable frame 22 is located above the longitudinal wave base 21, and the longitudinal wave base 21 has two oppositely arranged vertical frames 211, and the top of the vertical frame 211 has a crossbeam 212, and the two opposite sides of the longitudinal wave movable frame 22 are respectively between the crossbeam 212 of the vertical frame 211 and the longitudinal wave base 21; the longitudinal displacement elastic mechanism 23 includes two groups of second springs 231, each group of second springs 231 is arranged longitudinally, and each group includes two rows of second springs 231, and the two rows of second springs 231 are respectively between the crossbeam 212 and the side of the longitudinal wave movable frame 22 and the side of the longitudinal wave movable frame 22 and the longitudinal wave base 21, so that the longitudinal wave movable frame 22 maintains the longitudinal height through the second springs 231 arranged above and below. In this way, by periodically applying vertical force to the longitudinal wave movable frame 22, the longitudinal wave movable frame 22 will be elastically reciprocated in the longitudinal direction, thereby simulating longitudinal waves. The second locking mechanism 24 includes a second rotating rod 241 pivotally connected to the longitudinal wave base 21, a second ear plate 242 installed on the longitudinal wave movable frame 22 and used to receive the end of the second rotating rod 241, and a second pin shaft 243 for penetrating the second ear plate 242 and the end of the second rotating rod 241. In this way, the second ear plate 242 and the second rotating rod 241 can be penetrated by the second pin shaft 243, and the longitudinal wave movable frame 22 can be fixed to the longitudinal wave base 21 by the second rotating rod 241.

[0028] like Figure 2 Combined with Figure 3As shown, the composite wave simulation unit 30 includes: an upper plate 32, a lower plate 31, an elastic impedance cylinder 33 and a positioning mechanism; the upper plate 32 is located above the lower plate 31, the elastic impedance cylinder 33 is located between the upper plate 32 and the lower plate 31, the upper end of the elastic impedance cylinder 33 is fixedly connected to the upper plate 32, the lower end of the elastic impedance cylinder 33 is fixedly connected to the lower plate 31, and the elastic impedance cylinder 33 has an inwardly curved side wall, so that the elastic impedance cylinder 33 allows the upper plate 32 to swing relative to the lower plate 31. In some preferred structures, a plurality of circumferentially arranged through grooves 331 are provided on the side wall of the elastic impedance cylinder 33, and the plurality of through grooves 331 divide the side wall into a plurality of circumferentially arranged support bars 332, so that the elastic impedance cylinder 33 also allows the upper plate 32 to be twisted relative to the lower plate 31. The lower plate 31 of the composite wave simulation unit 30 is fixed to the transverse wave movable frame 12 of the transverse wave simulation unit 10, and the upper plate 32 of the composite wave simulation unit 30 is fixed to the longitudinal wave base 21 of the longitudinal wave simulation unit 20. The positioning mechanism includes a plurality of limit posts, which are arranged along the edges of the upper plate 32 and the lower plate 31; the ends of the limit posts are provided with studs, which pass through the mounting holes of the upper plate 32 and the lower plate 31 and are locked by nuts, so that the upper plate 32 and the lower plate 31 are fixed to restrict the upper plate 32 from swinging relative to the lower plate 31, and the restriction on the swing of the upper plate 32 and the lower plate 31 is released by unscrewing the nuts and removing the limit posts.

[0029] In some preferred embodiments, a plurality of support columns 112 arranged in a matrix are arranged on the shear wave base 11, and the upper ends of the plurality of support columns 112 are flush; a rolling top ball 113 is installed on the top of each support column 112, and the support column 112 with the top ball 113 supports the shear wave movable frame 12 by means of the top ball 113, so that when the shear wave movable frame 12 moves back and forth, the friction between the transverse movement base and the shear wave movable frame 12 is greatly reduced, thereby reducing the interference with the shear wave simulation, and the support column 112 with the top ball 113 allows the shear wave movable frame 12 to move in all directions.

[0030] The following describes how to use the above device.

[0031] When it is necessary to simulate the state of the electrical equipment when a transverse wave is applied to the electrical cabinet equipment 100, the second locking mechanism 24 is used to lock and fix the longitudinal wave base 21 and the longitudinal wave movable frame 22 of the longitudinal wave simulation unit 20, the positioning mechanism is used to lock and fix the upper plate 32 and the lower plate 31 of the compound wave simulation unit 30, and the first locking mechanism is used to unlock the transverse wave movable frame 12 and the transverse wave base 11 of the transverse wave simulation unit 10, and then, a transverse force is periodically applied to the transverse wave movable frame 12 so that the transverse wave movable frame 12 drives the electrical equipment to vibrate laterally.

[0032] When it is necessary to simulate the state of the electrical equipment when a longitudinal wave is applied to the electrical cabinet equipment 100, the transverse wave base 11 and the transverse wave movable frame 12 of the transverse wave simulation unit 10 are locked and fixed by the first locking mechanism 14, the upper plate 32 and the lower plate 31 of the composite wave simulation unit 30 are locked and fixed by the positioning mechanism, and the transverse wave movable frame 12 and the longitudinal wave base 21 of the longitudinal wave simulation unit 20 are unlocked by the second locking mechanism, and then, a vertical force is periodically applied to the longitudinal wave movable frame 22 so that the longitudinal wave movable frame 22 drives the electrical equipment to vibrate vertically back and forth.

[0033] When it is necessary to simulate the influence of swing on the operating state of the electrical cabinet equipment 100, the positioning mechanism is removed from between the upper plate 32 and the lower plate 31 of the composite wave simulation unit 30, so that the second locking mechanism 24 is in a locked or unlocked state, and the first locking mechanism 14 is switched to an unlocked state. Then, a lateral force is periodically applied to the transverse wave movable frame 12 so that the transverse wave movable frame 12 drives the electrical equipment to vibrate laterally. At the same time, the electrical cabinet equipment 100 swings due to the elastic deformation of the side wall of the elastic impedance cylinder 33, and the operating state of the electrical cabinet equipment 100 is monitored at this time.
