Diesel engine generator with spring support with variable height and vibration reduction control method thereof

Abstract

The invention aims to provide a diesel engine generator with a spring support with the variable height and a vibration reduction control method of the diesel engine generator. The support can be automatically adjusted along with the working condition of the diesel engine generator, and therefore the vibration reduction effect of the diesel engine generator is improved. The diesel engine generator comprises the support and a diesel engine generator body, and is characterized in that the support comprises a base plate, a supporting plate, a frame, springs, a height adjusting block, a stepping motor, a screw rod and a nut, wherein the nut is matched with the screw rod. The base plate is movably installed on the lower portion of the frame, and the springs, the supporting plate and the diesel engine generator body are arranged on the base plate in a supported mode in sequence from bottom to top. The height adjusting block and the stepping motor are arranged below the base plate, the top surface of the height adjusting block is an inclined surface, and the bottom surface of the base plate is a guide surface which is matched with the inclined surface. The nut is fixed to the side of the height adjusting block, and a motor shaft of the stepping motor is connected with the screw rod. The stepping motor controls movement of the height adjusting block according to the rotating speed of a crankshaft of the diesel engine generator body so as to change the height of the base plate.

Description

technical field [0001] The invention belongs to the technical field of diesel generators, and in particular relates to a diesel generator with a height-variable spring support and a vibration reduction control method thereof. Background technique [0002] Diesel generator is a small power generation equipment. It refers to the power machinery that uses diesel oil as fuel and diesel engine as the prime mover to drive the generator to generate electricity. It is generally a single structure, supported on the ground by a metal bracket, and does not have a vibration-damping seat. and other components for vibration reduction. When the diesel generator is working, it will generate large vibration and noise, which seriously affects the comfort of the working environment. [0003] In order to cope with the vibration of the diesel generator and the noise generated thereupon, the utility model patent with the patent number of 201420356530.5 proposes a vibration-damping mount that can...

Problems solved by technology

Although the above-mentioned vibration damping seat can reduce vibration at a certain frequency and eliminate certain noise, the most important thing is that the scope of application of the elastic damping body with its fixed structure is fixed, and the vibration frequency of the diesel generator and its crankshaft rotation speed Relevant, it is a very large frequency range, the vibration damping seat of the above patent is difficult to adapt to the vibration reduction of a wide frequency range
