[0054] As shown in the figure, the generator set of the present application can be transported separately and used together. As shown in the figure, when transported separately, the U-shaped connection unit is loosened and the synchronous belt is removed. And as shown in the figure, the generator set can use the first running wheel to move, and the gasoline unit can use the second running wheel to move, so as to achieve separate movement, so that a single generator set or gasoline unit can be set to a larger specification, so as to achieve split transportation. During transportation, the rubber plug of the U-shaped connection unit can be inserted into the end hole and limited by the limit bolt, making it more convenient to transport the U-shaped connection unit.

[0055] When it is necessary to assemble and use, as shown in the figure, two operators use the roller of the first support leg and the second support leg as support points from both sides, insert the limit plug into the limit plug hole (after insertion, the first and second travel wheels are not in contact with the ground), and push the generator unit so that the first base completely abuts the second base (at this time, the second end block is inserted into the rectangular plug hole), and use the fixing bolts to fix the two movable arms of the U-shaped connection unit to the two sides of the first base. At this time, the driving wheel and the driven wheel are close to each other, so that it is convenient to install the synchronous belt. After the installation is completed, the screw rod is rotated by a tool, so that under the drive of the screw rod, the two end blocks will move away from each other, and the first and second bases will move away from each other (the second support leg is fixed, but the first support leg has a roller, so as to facilitate the separation of the first and second bases), until the abutment block of the U-shaped connection unit abuts the abutment groove and cannot continue to extend, so that the synchronous belt is tightened, and the screw rod is also tightened and cannot continue to rotate. Then insert the limit detection block between the first base and the second base. In theory, the first, second and third limit reference blocks of the limit base are designed to just abut each component, and the measurement values ​​of the first and second pressure sensors should be within the set range. The indicator light is on (or the green light is on), thereby confirming that the spacing between the first and second bases and the spacing between the first and second sound insulation covers are qualified (the reason for failure may be, on the one hand, the adjustment problem, the first and second bases are not pulled apart enough; on the other hand, it may be due to the deformation of the first and second sound insulation covers, resulting in the spacing between the first and second bases being qualified, but the spacing between the first and second sound insulation covers being unqualified. At this time, the designated light is off (or the red light is on), thereby reminding the user to check and maintain), and the detection limit block is locked with the first and second bolts. Thus, the generator set can be used normally, and the roller is locked with the brake device, so that the generator set can be used normally. Since the first soundproof cover is firmly connected to the first base, and the second soundproof cover is firmly connected to the second base, the generator set body is mounted on the first mounting plate, and the gasoline engine body is mounted on the second mounting plate, thereby effectively achieving shock absorption. The generator assembly of the present application is transported using the first and second running wheels, but when fine-tuning the distance between the first and second bases and supporting the generator set for power generation, two second rollers and two second support legs are used for support. Because the diameter of the roller is very small, it has a smaller elastic deformation when supporting, so when supporting power generation, it can better ensure that the first and second bases are in a horizontal state, thereby ensuring the stability of power generation and the shock absorption effect of the first and second bases.

[0056] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0057] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
