Description

Technical Field

[0001] The invention relates to the technical field of generator sets, in particular to a gasoline generator set. Background Art

[0002] A generator is a power generation device that converts other energy into electrical energy, while a gasoline generator set uses gasoline combustion to drive the piston to move and do work, so that the piston drives the rotor of the generator to rotate through the crank connecting rod, achieving magnetic field cutting between the rotor and the stator, and thus completing power generation.

[0003] In the application process of gasoline generators, the actual work process is a variety of conversion methods including chemical energy-thermal energy-mechanical energy-electrical energy.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings:

[0029] According to the instruction manual Figure 1-5 It can be seen that a gasoline generator set is mainly composed of a generator base 1, a gasoline engine casing 2 and a piston engine chamber 3.

[0030] The gasoline engine housing 2 is arranged on the generator base 1, and a piston engine chamber 3 is provided on one side of the gasoline engine housing 2, and a gasoline engine output shaft 4 is movably installed on the gasoline engine housing 2. In the specific implementation process, the generator base 1 is the bottom support of the equipment, providing support for the equipment, and a shock-absorbing mobile mechanism is provided at the bottom of the generator base 1; the shock-absorbing mobile mechanism is used as a support for the movement of the equipment and a shock-absorbing foundation for the power generation process, and at the same time provides an installation foundation, and the gasoline engine housing 2 is used as a power mechanism for gasoline engine power generation, and the piston engine chamber 3 is a space for gasoline combustion to do work, and there is a piston cylinder in the piston engine chamber 3, and a crank connecting rod is installed on the piston cylinder, and the crank connecting rod is connected to the gasoline engine output shaft 4. The internal energy released by the combustion of gasoline in the piston cylinder is converted into the kinetic energy of the crank connecting rod movement, and then the crank connecting rod is used to drive the gasoline engine output shaft 4 to rotate, and then the gasoline engine output shaft 4 is used to drive the generator on one side to rotate, and the burned gas carries the remaining heat energy and is discharged through the exhaust pipe.

[0031] A heat exchange box 5 is provided on one side outside the piston engine chamber 3. The heat exchange box 5 is connected to the exhaust pipe of the piston engine chamber 3 through a heat recovery processing component. While the heat is recovered through the heat recovery processing component, the exhaust gas is more fully processed.

[0032] The heat recovery processing assembly includes a connecting pipe 6, one end of which is connected to the end of the air outlet pipe, and the connecting pipe 6 extends to the top of the heat exchange box 5. The connecting pipe 6 is inserted into the heat exchange box 5 and has a U-shaped structure with continuous turning. A gasoline tank 7 is arranged on one side of the heat exchange box 5, and a plurality of heat exchange fins 8 are arranged between the heat exchange box 5 and the gasoline tank 7.

[0033] The above-mentioned heat recovery treatment component also includes a filter box 9, which is installed on the connecting pipeline 6 and placed at the front end of the heat exchange box 5. A number of straight sections are arranged on the connecting pipeline 6, and a number of heat exchange internal threaded plates 10 are arranged on the number of straight sections. The ends of the number of straight sections are connected by a number of continuously reversed U-shaped bends, and a number of adsorption treatment materials 11 are arranged in the number of U-shaped bends.

[0034] In the specific implementation process, the heat exchange box 5 is a rectangular box body, and the heat exchange box 5 is filled with heat exchange medium. The connecting pipe 6 is connected from the exhaust pipe to the combustion exhaust gas, and the combustion exhaust gas passes through the filter box 9, and solid impurities are first filtered. The filtered combustion exhaust gas enters the U-shaped structure pipe section with continuous turning. The heat exchange internal threaded plate 10 on the inner side of the straight section connecting pipe 6 is fully in contact with the heat exchange exhaust gas, absorbs the heat in the exhaust gas and transmits it to the heat exchange medium. By using the cooperation of the heat exchange medium and the heat exchange plate 8, the gasoline inside the gasoline tank 7 can be fully preheated to improve the gasoline before combustion. The temperature makes gasoline easier to burn in colder weather, and the adsorption treatment material 11 arranged at the U-shaped bend adsorbs the exhaust gas, which can effectively remove easily adsorbed impurities in the exhaust gas.

A water outlet 16 is provided at the bottom of the heat exchange box 5, and the sealing plug 15 is threadedly connected to the water outlet 16. The water exchange port 14 is used to add heat exchange medium to the heat exchange box 5, and the water outlet 16 is used to discharge contaminated heat exchange medium.

The gasoline engine output shaft 4 drives the generator rotor to rotate through the coupling 17, so that the magnetic field of the generator rotor rotates and cuts the generator stator, thereby forming current and completing power generation.

[0037] Furthermore, an electrical installation back plate 19 is provided on one side of the generator base 1, and a control switch and a voltage indicator are provided on the electrical installation back plate 19. The generator power terminal is connected to the electrical installation back plate 19. The generator terminal is used to connect to external electrical equipment or batteries, and the control switch is used to control the switch of the generator power terminal, and the voltage indicator is used to measure the voltage.

[0038] Furthermore, a pair of lifting wrenches 20 are provided on both sides of the generator base 1, and a top cover 21 is connected to the pair of lifting handles, and the pair of lifting handles are used as push handles for moving the generator.

[0039] Furthermore, the adjacent back plates of the heat exchange box 5 and the gasoline tank 7 are a whole plate, and the heat exchange plates 8 are a plurality of rectangular thin plates located on both sides of the adjacent back plates of the heat exchange box 5 and the gasoline tank 7, thereby improving the gasoline preheating efficiency.

[0040] Furthermore, the above-mentioned shock-absorbing moving mechanism includes two pairs of shock-absorbing legs 22, and two pairs of shock-absorbing legs 22 are arranged at the bottom end of the generator base 1. A pair of symmetrically arranged assembly grooves 23 are arranged on the bottom surface of the generator base 1, and a rotating seat 24 is arranged in the middle section of the assembly groove 23. A rotating shaft 25 is movably installed on the rotating seat 24, and a pair of external thread grooves are symmetrically arranged on both sides of the rotating shaft 25. A pair of adjusting nuts 26 are sleeved on the pair of external thread grooves, and a pair of sliding blocks 27 are sleeved on the outside of the pair of adjusting nuts 26.

[0042] In the specific implementation process, two pairs of shock-absorbing legs 22 are used as supports for placing the generator on the ground, which play a role in reducing vibration and noise. By turning the rotating knob 32, the rotating shaft 25 is driven to rotate, so that the pair of external thread grooves on the rotating shaft 25 rotate and engage with the pair of adjusting nuts 26, so that the pair of adjusting nuts 26 move linearly on the external thread grooves, driving the pair of sliding blocks 27 to move symmetrically in the assembly groove 23, and then pushing the pair of first rotating rods 28 to move, and the pair of first rotating rods 28 move toward the pair of second rotating rods 29. Under the relative movement of the pair of second rotating rods 29 and the pair of first rotating rods 28, the shaft seat 30 moves downward to make the traveling roller 31 grounded, thereby achieving the effect of supporting the generator base 1, and then in conjunction with pushing the lifting handle, the generator base 1 can be pushed to move, thereby moving the generator more effortlessly.
