Technical Field

[0001] The utility model relates to the technical field related to generator sets, in particular to a shock-absorbing base of a generator set. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. The generator set is composed of a power system, a control system, a silencer system, a shock absorption system, and an exhaust system. The generator set will generate vibrations during use. If the vibrations are not weakened or buffered, the service life and power generation stability of the generator set will be affected. Therefore, a generator set shock-absorbing base is needed to weaken this vibration.

[0003] The prior art has the following deficiencies: the prior art "A shock-absorbing base for a generator set" with publication number CN214221891U "includes a generator, a mounting seat, a base and a mounting flange, the outer side of the base is fixed to the ground through the mounting flange, the base is a box-type structure with an opening on the top, the inside of the base is slidably connected with the mounting seat, and the top of the mounting seat is fixed with a generator; the bottom of the mounting seat is symmetrically distributed along the center with a plurality of groups of second buffer mechanisms, the generator is fixedly mounted on the upper surface of the mounting seat, and the mounting seat is restricted inside the base by the box-type structure of the base";

[0004] The above-mentioned equipment uses a mounting base and multiple sets of springs to reduce the shock of the generator set, but the overall size of the mounting base is large, which is not convenient for users to install and fix conveniently. At the same time, when reducing shock, only the vibration force in the up and down directions can be weakened, and the shock reduction effect in other directions is poor. Moreover, the spring alone cannot play a shock-absorbing role, but will increase the vibration. Utility Model Content

The first limit frame is installed at the top end of the support plate through bolts. The two groups of first damping shock absorbers are symmetrically installed at the top end of the support plate. The multiple groups of second damping shock absorbers are symmetrically installed at the inner bottom of the first limit block. The pressing block is installed at the top end of the second damping shock absorber. The second limit frame is installed at the top end of the pressing block through bolts. The multiple groups of third damping shock absorbers are symmetrically installed on the inner wall of the second limit frame.

[0015] (1) The utility model is provided with a shock absorbing component. When the user rotates the handle, the rotation of the handle drives the transmission screw to rotate. The rotation of the transmission screw drives the two sets of screw nuts to move closer to or away from each other. The movement of the screw nuts drives the support plate to move. The movement of the support plate drives the fixed frame above it to move. The distance between the fixed frames can be adjusted, which is convenient for supporting and shock absorbing mounting seats of different sizes. When the generator set is used, the vibration generated by the generator set is transmitted to the fixed frame through the mounting seat. Under the setting of the third damping shock absorber, the vibration in the front and rear and left and right directions can be buffered and weakened. At the same time, the fixed frame causes the second limit frame to be pressed down. The downward pressure of the second limit frame causes the downward pressure block to be pressed down.

The support plate 9 is installed on the top of the screw nut 8 by bolts, and the buffer part 10 is installed above the support plate 9. The user rotates the rotating handle 7, and the rotation of the rotating handle 7 drives the transmission screw 6 to rotate. The rotation of the transmission screw 6 drives the two groups of screw nuts 8 to move closer to or away from each other. The movement of the screw nut 8 drives the support plate 9 to move, and the movement of the support plate 9 drives the fixed frame 18 above it to move. The distance between the fixed frames 18 can be adjusted, which is convenient for supporting and shock-absorbing mounting seats 1 of different sizes. The buffer part 10 includes a first limit frame 11, two groups of A damping shock absorber 12, multiple groups of second damping shock absorbers 13, a lower pressure block 14, a second limit frame 15 and multiple groups of third damping shock absorbers 16, the No. 1 limit frame 11 is installed on the top of the support plate 9 by bolts, two groups of the first damping shock absorbers 12 are symmetrically installed on the top of the support plate 9, multiple groups of the second damping shock absorbers 13 are symmetrically installed on the bottom of the No. 1 limit block 19, the lower pressure block 14 is installed on the top of the second damping shock absorber 13, the No. 2 limit frame 15 is installed on the top of the lower pressure block 14 by bolts, and multiple groups of the third damping shock absorbers 16 are symmetrically installed on the inner wall of the No. 2 limit frame 15, a cavity is opened in the fixing seat 5, and two groups of external threads are opened on the surface of the transmission screw 6.

Under the setting of the third damping shock absorber 16, the vibration in the front and rear directions and the left and right directions can be buffered and weakened. At the same time, the fixing frame 18 causes the No. 2 limit frame 15 to be pressed down, and the downward pressure of the No. 2 limit frame 15 causes the pressing block 14 to be pressed down. Under the setting of the first damping shock absorber 12 and the second damping shock absorber 13, the vibration in the up and down directions is buffered and weakened, thereby achieving a good shock absorption effect.

[0025] The utility model provides a shock-absorbing base for a generator set, and the specific working principle is as follows:

[0026] When using this shock-absorbing base for a generator set, the shock-absorbing pad 17 can protect the fixing seat 5 and at the same time buffer and weaken the overall vibration. By providing a shock-absorbing component 3, the user rotates the rotating handle 7. The rotation of the rotating handle 7 drives the transmission screw rod 6 to rotate. The rotation of the transmission screw rod 6 drives the two screw nuts 8 to approach or move away from each other. The movement of the screw nuts 8 drives the support plate 9 to move. The movement of the support plate 9 drives the fixing frame 18 above it to move, and the distance between the fixing frames 18 can be adjusted, facilitating the support and shock absorption of mounting seats 1 of different sizes. When the generator set 2 is used, the vibration generated by the generator set 2 is transmitted to the fixing frame 18 through the mounting seat 1. Under the setting of the third damping shock absorber 16, the vibration in the front-back and left-right directions can be buffered and weakened. At the same time, the fixing frame 18 causes the second limiting frame 15 to press down. The downward pressure of the second limiting frame 15 causes the downward pressing block 14 to press down. Under the setting of the first damping shock absorber 12 and the second damping shock absorber 13, the vibration in the up-down direction is buffered and weakened, realizing a good shock-absorbing effect. By providing a fixing component 4, after adjusting the distance between the fixing frames 18, the fixing frame 18 is sleeved outside the mounting seat 1. Subsequently, the user rotates the threaded rod 20. Under the limitation of the limiting blocks 19, the rotation of the threaded rod 20 causes the threaded rod 20 itself to move. The movement of the threaded rod 20 drives the clamping plate 21 to move, and the fixing frame 18 and the mounting seat 1 can be limited and fixed, realizing the convenient installation and fixation between the mounting seat 1 and the shock absorption structure.
