When multiple units are used together, power aggregation is difficult, and the lack of seamless grid connection technology can easily cause impacts on electrical equipment. In addition, existing generators lack auxiliary functions, which means they cannot meet the lighting requirements for nighttime operations, reducing operational safety and making them unsuitable for long-term continuous operation.

[0023] The structure of the self-loading and unloading synchronous grid-connected generator provided by this utility model is as follows: Figures 1 to 5 As shown, the generator set includes a generator body 1, and the surface of the generator body 1 is provided with a generator main controller 11, a convenient loading and unloading mechanism 2, and an auxiliary lighting and warning mechanism 3.

[0024] Furthermore, such as Figure 6 As shown, a generator main controller 11 is installed on the surface of the generator set body 1. The generator main controller 11 can be of the LA series. The generator main controller 11 adopts an integrated operation panel and is equipped with an LCD display screen, which can display equipment operating parameters such as three-phase voltage, three-phase current, frequency, power, oil pressure, water temperature, and power factor in real time.

[0025] Furthermore, such as Figure 2 and Figure 4As shown, the surface of the generator set body 1 is provided with a convenient loading and unloading mechanism 2. The convenient loading and unloading mechanism 2 is used for the self-loading and unloading of the generator set body 1. The convenient loading and unloading mechanism 2 includes self-loading and unloading metal support legs 21, electric lifting push rods 22, force conversion support legs 23, positioning pin holes 24, tumbleable retraction wheels 25, and support leg retraction electric push rods 26. Two sets of support leg retraction electric push rods 26 are symmetrically arranged on the surface of the generator set body 1. The model of the support leg retraction electric push rods 26 can be selected from the DG series. The input end of the support leg retraction electric push rods 26 is electrically connected to the output end of the generator main controller 11. The support leg retraction electric push rods 26 are used for the unfolding and retraction of the self-loading and unloading metal support legs 21. Four sets of force conversion support legs 23 are symmetrically arranged on the surface of the generator set body 1. The force conversion support legs 23 rotate with the surface of the generator set body 1. The output end of the support leg retraction electric push rods 26 is connected to the force conversion support legs 23. The surfaces of the legs 23 rotate with each other. Two sets of self-loading and unloading metal support legs 21 are symmetrically arranged on one side of the generator set body 1. The other end of the force conversion support leg 23 rotates with the surface of the self-loading and unloading metal support leg 21. An electric lifting push rod 22 is installed on the surface of the self-loading and unloading metal support leg 21. The model of the electric push rod 22 can be selected from the DG series. The input end of the electric lifting push rod 22 is electrically connected to the output end of the generator main controller 11. The electric lifting push rod 22 is used to push the internal metal parts of the self-loading and unloading metal support leg 21 to lift. The surface of the force conversion support leg 23 is provided with a positioning pin hole 24. The surface of the positioning pin hole 24 is provided with a pin body, and the pin body and the positioning pin hole 24 cooperate with each other. Four sets of flip-up retractable wheels 25 are installed at the corner position at the bottom of the generator set body 1. The flip-up retractable wheels 25 are used for moving the generator set body 1 during loading and unloading.

[0026] During implementation, the outrigger extension / retraction electric push rod 26 is controlled. The extension / retraction range of the electric push rod 26 is customized, automatically stopping when fully extended and automatically stopping when fully retracted. The electric push rod 26 pushes the force-transfer outrigger 23, unfolding the self-loading / unloading metal support leg 21. Once in position, the pin body is inserted into the positioning pin hole 24. Subsequently, the electric lifting push rod 22 is controlled. The extension / retraction range of the electric lifting push rod 22 is customized, automatically stopping when fully extended and automatically stopping when fully retracted. This can drive the lifting and lowering of the internal metal parts of the self-loading / unloading metal support leg 21, thereby controlling the generator set. The generator set body 1 is raised to a height of 1 meter. After the bottom of the generator set body 1 is raised to a height higher than the rear bed of the pickup truck or small flatbed, the pickup truck or small truck reverses in and places the generator set body 1 inside the truck bed. Then, the electric lifting push rod 22 is controlled to lower the generator set body 1 onto the pickup truck or small flatbed. After it is placed in place, the pin body is pulled out from the positioning pin hole 24, and the outrigger retraction electric push rod 26 is controlled to work, so that the self-loading and unloading metal support leg 21 is retracted into the truck bed, so as to realize the function of convenient loading and unloading of the generator.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, an auxiliary lighting warning mechanism 3 is provided on the surface of the generator set body 1. The auxiliary lighting warning mechanism 3 is used for warning and lighting the generator set body 1. The auxiliary lighting warning mechanism 3 includes a warning line light 31, a translucent light 32, and a floodlight 33. The translucent light 32 is installed on the surface of the generator set body 1. The input end of the translucent light 32 is electrically connected to the output end of the generator main controller 11. The height of the translucent light 32 can be adjusted. Warning line lights 31 are installed in four directions on the surface of the generator set body 1. The input end of the warning line lights 31 is electrically connected to the output end of the generator main controller 11. The warning line lights 31 are used to form a red warning area around the working area of ​​the generator set body 1. A floodlight 33 is also installed on the surface at the top of the generator set body 1. The input end of the floodlight 33 is electrically connected to the output end of the generator main controller 11. The floodlight 33 is used to illuminate the area around the generator set body 1.

[0028] During implementation, when the generator set 1 is operating at night or in a complex environment, the translucent lamp 32 and floodlight 33 are turned on, and the warning line lamp 31 is turned on during operation. This creates a red warning zone around the generator set 1, improving operational safety. The floodlight 33 meets the lighting requirements for nighttime and complex environments. The layout design of the warning line lamp 31, translucent lamp 32, and floodlight 33 integrates lighting and safety warning in the work area, thus realizing the function of auxiliary lighting warning for the generator.

[0029] Working Principle: In use, first place the generator set body 1 in the designated position. Then, operate the outrigger extension / retraction electric push rod 26. The extension / retraction range of the electric push rod 26 is customized, automatically stopping when fully extended and automatically stopping when fully retracted. The electric push rod 26 pushes the force-transfer outrigger 23, unfolding the self-loading / unloading metal support leg 21. After it reaches its position, insert the pin body into the positioning pin hole 24. Subsequently, operate the electric lifting push rod 22. The extension / retraction range of the electric lifting push rod 22 is customized, automatically stopping when fully extended and automatically stopping when fully retracted. This pushes the internal metal parts of the self-loading / unloading metal support leg 21 to lift the generator set body 1. The lifting height of the generator set body 1 can reach 1.1 meters. After the bottom of the generator set body 1 is raised to a height higher than the rear bed of a pickup truck or small flatbed truck, the pickup truck or small truck reverses in and places the generator set body 1 inside the truck bed. Then, the electric lifting push rod 22 is controlled to lower the generator set body 1 onto the pickup truck or small flatbed truck bed. After it is placed in place, the pin body is pulled out from the positioning pin hole 24, and the outrigger retraction electric push rod 26 is controlled to work, so that the self-loading and unloading metal support leg 21 is retracted into the truck bed, thereby realizing the function of convenient loading and unloading of the generator. This allows the generator to be quickly docked and unloaded when in use, without the need for crane or forklift assistance, eliminating the dependence on cranes and forklifts, greatly improving loading and unloading efficiency, and adapting to various working sites.

[0030] Subsequently, during synchronous grid connection, the voltage, frequency, and phase difference between the grid and the generator set are detected by the generator main controller 11, realizing forward primary and reverse secondary sensorless grid connection or disconnection. The synchronous grid connection system consists of the generator main controller 11, generator switch, mains switch, bus clamp, mains input terminal block, and grid connection output terminal block. The grid connection point needs to meet the requirement that there is a user power supply switch on the original line. A set of cables is connected to the generator mains input terminal block to the front end of the user power supply switch for live connection, using live tools such as bus clamp. A set of cables is connected to the generator grid connection output terminal block to the rear end of the user power supply switch for live connection, using live tools such as bus clamp. Turn on the power switch of the generator main controller 11. After the generator main controller 11 detects that there is power in the mains input and grid output before and after the mains switch and the phase is consistent, it automatically closes the mains switch. After closing, manually disconnect the "user power supply switch". At this time, the power supply to the user load is changed from the original power supply to the user load through the "user power supply switch" to bypass the load by powering the user load through the generator "mains switch". At this time, select the generator mode to enter the automatic mode. After turning the grid connection switch to "close", the generator automatically starts and collects the grid voltage, frequency and phase parameters. Adjust the generator parameters to be consistent with the grid parameters. The voltage difference is 3V, the frequency difference is 0.1 and the phase difference is 10°. The generator automatically closes the "generator switch" to connect the generator's power to the grid mains and immediately disconnects the "mains switch". At this time, the forward grid connection is completed and the generator is used to carry the load alone.

[0031] After the power grid is repaired and energized, the grid connection switch is switched to "off". The generator main controller 11 automatically detects the mains voltage, frequency, and phase parameters, and adjusts the generator parameters to match the mains parameters: voltage difference 3V, frequency difference 0.1, and phase difference 10°. It then automatically closes the "mains switch" to connect the grid power to the generator and immediately disconnects the "generator switch", causing the generator to automatically stop. At this point, the reverse secondary grid connection is complete. The user power supply switch can then be manually closed, the bus clamp removed, and power restored. This enables flexible grid connection of the generator, allowing multiple generator sets of the same model to be connected in parallel for power aggregation. By configuring the generator main controller 11, multi-dimensional operating parameters can be centrally displayed, facilitating real-time monitoring of equipment status and timely troubleshooting. The status monitoring is intuitive.

[0032] Subsequently, when the generator set 1 is operating at night or in complex environments, the translucent light 32 and floodlight 33 are turned on, and the warning light 31 is turned on during operation. This creates a red warning zone around the generator set 1, improving operational safety. The floodlight 33 provides illumination for nighttime and complex environments. The layout of the warning light 31, translucent light 32, and floodlight 33 integrates illumination and safety warning in the work area, enabling the generator to provide auxiliary lighting and warning functions. This allows the generator to meet the lighting requirements for nighttime operations, while the multi-directional warning lights enhance operational safety. The large-capacity battery extends the equipment's battery life, allowing for continuous operation over extended periods, ultimately completing the generator's operation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
