Description
Technical Field
[0001] The utility model relates to the technical field of internal combustion engine oil pans, in particular to an internal combustion engine oil pan structure of a generator. Background Art
[0002] The oil pan of an internal combustion engine is located at the bottom of the engine, forming the lower half of the crankcase, also known as the lower crankcase. Its primary function is to seal the crankcase and act as a reservoir for the oil, preventing impurities from entering the engine. The oil pan also collects and stores lubricating oil that flows back from the engine's friction surfaces, dissipating some of the heat and preventing oxidation. A drain plug is located at the bottom of the oil pan to facilitate removal of used oil during oil changes.
[0003] The oil drain plug at the bottom of the oil pan of the internal combustion engine of the existing generator is generally set directly at the bottom of the oil pan, and is directly opened when maintenance and oil drainage is required. However, during maintenance, the oil pan is at a certain height from the ground, which makes it inconvenient to collect the oil when draining it, and oil will splash on the maintenance personnel. In addition, the existing oil pan generally dissipates heat through its own structure, and the heat dissipation efficiency is low. Utility Model Content
[0004] The purpose of the utility model is to provide an oil pan structure of an internal combustion engine of a generator. When it is necessary to maintain and discharge the internal oil, the sealing cover can be rotated first so that the sealing cover is only connected to the lower oil outlet pipe, and then the clamping strip can be bent to separate the clamping block from the lower oil outlet pipe, thereby releasing the folding tube, which is convenient for pulling the folding tube down to the oil receiving device, and finally the sealing cover can be rotated again to separate the sealing cover from the lower oil outlet pipe to perform the oil draining operation. Not only is the operation safer, but the oil draining is also more convenient. A refrigeration plate is provided at the bottom of the oil pan shell to cool the internal oil, thereby improving the heat dissipation efficiency of the oil pan shell.
