The tops of the plurality of guide rods 13 are commonly fixedly connected with a mounting plate 11. The four corners of the surface of the mounting plate 11 are provided with mounting holes 12. A second support spring 16 is arranged at the center of the bottom of the inner wall of the piston cylinder 3. A first support spring 14 is arranged on the top surface of the spring baffle 4. The first support spring 14 is sleeved on the outside of the guide rod 13. The second support spring 16 is between the inner wall of the piston cylinder 3 and the bottom surface of the piston 15. The length of the first support spring 14 after reset is greater than the length of the guide rod 13. The length of the second support spring 16 after reset is greater than the height of the inner wall of the piston cylinder 3.

[0023] As an optional technical solution of the utility model, the one-way sealing cover 6 is flipped upward to open, and a reset coil spring is provided at the connection between the one-way sealing cover 6 and the exhaust pipe 5. The rolled end and the fixed end of the reset coil spring are respectively fixedly connected to the one-way sealing cover 6 and the exhaust pipe 5.

[0026] A vibration-absorbing base for a diesel generator set, the working principle is as follows:

[0027] 1) The sliding of the piston cylinder 3 and the piston 15 can buffer the vibration of the diesel generator set on the top surface of the mounting plate 11. When the piston 15 slides down, the one-way sealing cover 6 can be quickly pushed open, so that the gas inside the piston cylinder 3 is quickly discharged, and efficient buffer sliding can be quickly achieved;

[0028] 2) The kinetic energy is then absorbed by the first support spring 14 and the second support spring 16;

[0029] 3) When the second support spring 16 rebounds, the piston moves upward to draw in the air flow at the bottom. The inhaled air flow is restricted by the one-way sealing cover 6 that closes the exhaust pipe 5, which slows down the speed at which the gas enters, thereby weakening the speed at which the piston 15 returns upward, so that the energy stored in the first support spring 14 and the second support spring 16 is slowly released to achieve buffering.

[0030] In summary, the diesel generator set uses a shock-absorbing base, which can buffer the vibration of the diesel generator set on the top surface of the mounting plate 11 through the sliding of the piston cylinder 3 and the piston 15, absorb kinetic energy through the first support spring 14 and the second support spring 16, and when rebounding, it is restricted by the one-way sealing cover 6 to close the exhaust pipe 5, slowing down the speed of gas entry, weakening the speed of piston 15 resetting, and slowly releasing the energy stored in the first support spring 14 and the second support spring 16, thereby achieving shock absorption. The diesel generator set and the fixing bolts are fixed to the mounting plate 11 together, so that the diesel generator set and the fixing bolts are synchronously buffered and moved during vibration, thereby reducing the relative movement of the fixing bolts and the diesel generator set and reducing the loosening of the bolts. At the same time, the piston cylinder 3 and the piston 15 can greatly absorb the impact force, which can greatly reduce the vibration of the fixing foot 9 and improve its stability in fixing to the ground.
