The beneficial effects of the invention are as follows: the mechanical and electrical equipment is arranged in the installation space of the chassis, a plurality of limiting seats surround the periphery of the mechanical and electrical equipment, and as the working side wall of each limiting seat is provided with a damping component, each damping component comprises a plurality of dampers which are arranged at intervals along the up-down direction, the dampers surround the periphery of the mechanical and electrical equipment, and when the mechanical and electrical equipment operates to generate vibration, all the dampers consume vibration energy in the horizontal direction of the mechanical and electrical equipment, so that the vibration in the horizontal direction of the mechanical and electrical equipment is reduced; in addition, the amplitude of the shaking of the electromechanical equipment gradually decreases from top to bottom, and as the damping coefficients of all the dampers gradually decrease from top to bottom, the damping coefficient of the damper positioned above is larger, and the capability of reducing the vibration energy of the electromechanical equipment at the height is better; the vibration frequency of the electromechanical device gradually increases from top to bottom, and the damping coefficient of the damper positioned below is smaller, so that the buffer action of the damper can be matched with the vibration frequency of the electromechanical device at the height, the vibration energy of the electromechanical device at high frequency is consumed, and the electromechanical device is prevented from impacting the damper positioned below at high frequency.
As a further improvement of the above technical solution, each damping assembly includes at least three dampers, and the interval between every two upper and lower adjacent dampers gradually decreases from top to bottom.
Since the damping coefficient of the damper located below is smaller, the interval between every two upper and lower adjacent dampers gradually decreases from top to bottom, i.e. the dampers located below are denser, thereby helping to consume vibration energy of the electromechanical device at that height.

When the amplitude of the vibration of the electromechanical device in a certain direction is larger, the limiting seats in the direction are impacted more, every two adjacent limiting seats are detachably connected, all the limiting seats are connected together, and therefore the other limiting seats can help to disperse vibration energy.
As a further improvement of the technical scheme, the side wall of each limit seat is provided with a lug and a groove, the positions between two adjacent limit seats are in opposite left and right directions, the lug and the groove are respectively arranged on the left and right side walls of the limit seat, the groove extends along the up and down direction, the shape of the lug is matched with that of the groove, and the adjacent lug is in fit and clamping connection with the groove.
