Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, in particular to a diesel generator set transportation buffer platform. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a silencer system, a shock absorption system, and an exhaust system. It is driven by a turbine, a steam turbine, a diesel engine, or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy and outputs it to electrical equipment for use. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. In recent years, with the advancement of technology, as a high-quality choice for home emergency power supply and outdoor travel power supply, lightweight and portable small generator sets have also begun to enter the daily lives of residents.

[0003] The size of the generator set shrinks and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, and the volume expands rapidly, pushing the piston downward, which is called "work". Each cylinder works in a certain order, and the thrust acting on the piston is transformed into a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. Using the principle of "electromagnetic induction", the generator will output an induced electromotive force, and current can be generated through a closed load circuit. Here we only describe the most basic working principle of the generator set. In order to obtain usable and stable power output, a series of diesel engine and generator control, protection devices and circuits are also required.

[0004] Diesel generator sets will be deformed and damaged due to impact loads during transportation. Therefore, it is necessary to reduce the impact loads during transportation of generator sets on bumpy roads to reduce the deformation and damage caused by impact loads to the generator sets and bases.

DETAILED DESCRIPTION

[0015] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0016] A diesel generator transport buffer platform comprises a spring limit shaft fixing seat 1, a spring 2, a spring limit shaft 3, a spring limit shaft slide groove 4, a buffer limit slot 5, a unit fixing platform 6, a stiffness adjustment structure 7, a vibration avoidance structure 8, and a buffer platform base 9; wherein: the unit fixing platform 6 is arranged on the top of the stiffness adjustment structure 7, and the vibration avoidance structure 8 is arranged on the bottom of the stiffness adjustment structure 7; the outer end of the unit fixing platform 6 is fixed to the top of the buffer limit slot 5 by bolts, and the outer end of the vibration avoidance structure 8 is fixed to the bottom of the buffer limit slot 5 by bolts.

[0017] A stiffness adjustment limit shaft 702 runs through the stiffness adjustment structure 7, the top end of the stiffness adjustment limit shaft 702 is inserted into the unit fixed platform 6, the bottom end of the stiffness adjustment limit shaft 702 is inserted into the vibration avoidance structure 8, the top of the stiffness adjustment limit shaft 702 is sleeved with the unit fixed platform spring 701, and the bottom of the stiffness adjustment limit shaft 702 is sleeved with the vibration avoidance structure spring 703.

[0018] The outer end of the vibration-proof structure 8 is fixed to the buffer platform base 9 by bolts.

[0019] The buffer limit slot 5 is a U-shaped structure, and the middle part of the buffer limit slot 5 is connected to the bottom of the spring limit shaft slot 4 through the spring 2 and the spring limit shaft 3; the top of the spring limit shaft fixing seat 1 is connected to the top of the spring limit shaft slot 4 through the spring 2 and the spring limit shaft 3.

[0020] The principle of diesel generator transport buffer platform: This platform mainly uses springs or other elastic bodies to replace springs to achieve vertical, lateral and longitudinal impact mitigation. The distribution and type of each spring are adjusted according to the shape, weight, center of gravity and other related information of the unit. The rigid adjustment structure is a layer of plate and a layer of elastic body. The multi-layer structure is used to adjust the platform stiffness. The lateral and longitudinal elastic bodies are adjusted according to the predetermined transportation road conditions. For small and medium-sized unit platforms, the springs use unequal pitch compression springs. When the spring is compressed to the point where the spring coil begins to contact, the characteristic line becomes nonlinear, and the stiffness and natural frequency are variables, which is conducive to eliminating or easing resonance.

[0021] If the weight of this diesel generator transport buffer platform exceeds the range of the spring, other springs with stronger elasticity (such as disc springs, rubber-metal spiral composite springs, leaf springs, etc.) can be used in conjunction with other diesel generator transport buffer platforms. Heavy-duty units can also use steel-rubber composite plates to replace springs. According to the Young's modulus of the rubber or elastomer and the maximum impact load during transportation, laminated composite plates can be used in the shock absorption system in all directions to control the buffer stroke and the service life of the elastomer.

[0022] The above detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention but merely represents selected embodiments of the present invention.
