Description

Technical Field

[0001] This utility model relates to the field of refueling technology, and in particular to an outdoor small skid-mounted automatic fuel supply device for diesel generator sets. Background Technology

[0002] Diesel generator sets are power generation devices that use diesel fuel as their energy source, and are widely used in mobile outdoor work equipment such as mobile lighting towers. Because the fuel tank capacity of diesel generator sets is limited, they require continuous refueling to ensure normal operation. Currently, fuel supply to diesel generator sets is mainly achieved through fuel storage tanks, fuel supply pipelines, and solenoid valves and controllers. Automatic fuel supply is achieved by using a fuel tank level sensor to control the solenoid valves via the controller. This type of fuel supply device is a temporary installation on-site, lacking protective measures. In complex and changing outdoor environments, such as rain and snow infiltration, sand accumulation, and easy corrosion or aging of components, it is prone to device failure, shortening equipment lifespan. Furthermore, it is inconvenient for rapid relocation, and temporary installation is time-consuming and labor-intensive, affecting construction efficiency.

[0003] Based on this, this application provides a small, skid-mounted, automatic fuel supply device for diesel generator sets that is small, highly protective, well-ventilated, and easy to transport, in order to solve the above problems. Utility Model Content
