Description
Technical Field
[0001] The utility model relates to the technical field of combustion generators, and particularly relates to a small generator set. Background Art
[0002] Generators have a wide range of applications in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of its structure is: using appropriate magnetic and conductive materials to form a magnetic circuit and an electric circuit that mutually perform electromagnetic induction to generate electromagnetic power and achieve the purpose of energy conversion. Among them, most small power generation equipment uses diesel, gasoline, etc. as fuel, such as a power machine that drives a generator to generate electricity with a diesel engine as the prime mover. The whole set of units generally consists of components such as a diesel engine, a generator, a control box, a fuel tank, a starting and control storage battery, a protection device, and an emergency cabinet.
[0003] Chinese patent document CN213711183U discloses a residential and commercial silent gas generator set, including a housing. An electric control box, a generator, an engine, a cooling fan, and a cooling water tank are sequentially arranged in the housing along the length direction. Air inlets are respectively arranged at the positions corresponding to the electric control box and the generator in the circumferential direction of the housing, and an air outlet is arranged at one end close to the cooling water tank. The cooling fan can attract external air flow to enter the housing from the air inlet, flow through the corresponding electric control box and / or the generator, then sequentially pass through the engine and the cooling water tank, and be discharged out of the housing from the air outlet. The installation position of the electric control box in the housing is higher than the installation positions of the generator and the engine, so that the generator, the engine, and the electric control box are staggered from each other in the height direction, and most of the external air flow inhaled from the end air inlet can directly blow to the generator and the engine without being blocked by the electric control box.
[0004] The existing technology has the following deficiencies: In the existing generator set, the transverse dimension of the engine is narrow and the longitudinal dimension is long, and the overall dimension of the generator connected to the engine is smaller. The housing of the generator set itself is a rectangular structure, resulting in a small utilization rate of the transverse space inside the housing. Therefore, the overall volume of the generator set is large. Summary of the Utility Model
[0005] The utility model aims to provide a small generator set, which comprises a shell, a generator, an engine, a fuel tank, an electric control box and a heat dissipation mechanism. The heat dissipation mechanism is arranged near the air outlet of the shell. The electric control box and the generator are arranged near the air inlet of the shell. The engine is arranged between the heat dissipation mechanism and the generator. The engine is connected to the generator. It is characterized in that long columns and short columns are arranged on both sides of the chassis of the shell. The long columns and the short columns are connected to both sides of the engine. The engine is obliquely arranged in the shell. The fuel tank is fixed on the chassis. The generator is above the fuel tank, and the electric control box is above the generator.
[0006] In order to ensure the support strength without enlarging the size of the shell, the long columns and the short columns are rectangular columns. Grooves are arranged on the lower side edges of the long columns and the short columns. On the left and right sides of the chassis, the grooves are matched with the edges of the chassis. The upper parts of the long columns and the short columns are in the same vertical plane as the edges of the chassis, reducing the lateral proportion of the long columns and the short columns, so that the inclination angle of the generator is larger and the longitudinal dimension is smaller.
[0007] Preferably, connectors are arranged on both sides of the engine. Shock-absorbing blocks in the shape of cylinders are arranged at the ends of the connectors. The shock-absorbing blocks are respectively fixedly connected to the long columns and the short columns.
[0008] Preferably, the tops of the long columns and the short columns are hollow and have notches on the side facing the engine. The shock-absorbing blocks on both sides of the engine are respectively located inside the column bodies at the tops of the long columns and the short columns. Both ends of the shock-absorbing blocks are fixedly connected to the two side surfaces of the column bodies.
[0009] In order to increase the capacity of the fuel tank while reducing the volume ratio, the fuel tank is of an L-shaped structure, including a vertical part and a horizontal part. The generator is located on the horizontal part and is arranged side by side with the vertical part.
[0010] In order to facilitate the support of the electric control box, a support plate is connected to the vertical part of the fuel tank. The support plate is supported and connected to one side of the bottom of the electric control box. The other side of the bottom of the electric control box is supported by a support cross beam connecting the shell. The side surface of the electric control box is attached to the shell.
[0011] In order to facilitate the adjustment of the height of the columns, both the long columns and the short columns include upper columns and lower columns. The upper columns are inserted into the lower columns. Limiting holes are arranged on both sides of the lower columns. Limiting bolts are arranged in the limiting holes. The upper columns are fixed in the lower columns through the limiting bolts. The tops of the upper columns are the notches. The bottoms of the lower columns are connected to bottom plates. The lower side edges of the lower columns are the grooves.
[0012] The utility model has the following beneficial effects:
[0013] 1. By rotating the engine, the present utility model reduces the longitudinal height, making the lateral utilization rate higher. Moreover, the crossbeam of the chassis is cancelled, and the engine can be directly supported by long and short columns at the left and right ends of the chassis, enabling the engine to move downward and have a larger rotation angle, with a smaller shell volume, a more compact internal structure of the shell, and the overall engine being more miniaturized.
[0014] 2. The engine has a larger fuel storage capacity and a longer service life, which is more conducive to long-term outdoor power generation. BRIEF DESCRIPTION OF THE DRAWINGS
