Description

Technical Field

[0001] This utility model belongs to the field of engine technology, and in particular relates to an automatic oil replenishment device for a base oil tank. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Internal combustion engines, for example, typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit.

[0003] Installing a refill device at the bottom of the base oil tank helps to replenish the oil level in the engine's fuel tank, thereby extending the engine's operating time. However, different base oil tanks have different pre-reserved installation positions at the bottom, making it difficult for ordinary refill devices to be installed and used effectively. To solve the above problems, it is necessary to provide a more applicable automatic refill device for base oil tanks. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides an automatic oil replenishment device for a base oil tank, including an oil storage tank 1: an oil discharge component 2 is connected to the discharge end of the oil storage tank 1, a sealing plug 4 is connected to the inlet end of the oil storage tank 1, and a positioning component 3 is provided on the outer wall of the oil storage tank 1.

[0027] Among them, the oil discharge assembly 2 includes an oil discharge head mechanism 201, the feed end of the oil discharge head mechanism 201 is connected to a one-way oil discharge pipe 202, and the feed end of the one-way oil discharge pipe 202 is connected to a supplementary pump 203.

[0028] The oil discharge head mechanism 201 includes a first mounting flange 2011, a telescopic pipe 2012 connected to the bottom of the first mounting flange 2011, a feed seat 2013 fixedly connected to the feed end of the telescopic pipe 2012, and a hose 2014 fixedly connected to the feed end of the feed seat 2013.

[0029] The inner wall of the one-way oil drain pipe 202 is provided with straight branch channels and several curved branch channels.

[0031] The lifting rod includes a threaded rod and a screw barrel, which are connected by threads. The bottom of the screw barrel is fixedly connected to the inner wall of the feed seat 2013, and the top of the threaded rod is fixedly connected to the bottom of the oil level monitoring probe.

[0032] It should be noted that while existing fuel replenishment devices installed at the bottom of the base oil tank help to replenish the fuel in the engine mechanism oil tank, thereby extending the engine's operating time, the installation positions reserved at the bottom of different base oil tanks are different, making it difficult for ordinary fuel replenishment devices to be installed and used effectively.

[0033] Specifically, in this embodiment, the solution mainly uses the oil storage tank 1, the oil drain assembly 2, the sealing plug 4, and the positioning assembly 3 in combination. In use, firstly, according to the position of the base oil tank, the oil drain assembly 2 is fixedly connected to the oil inlet of the base oil tank through the first mounting flange 2011. Then, according to the structure near the bottom of the base oil tank, a suitable position is selected, and the positioning assembly 3 and the oil storage tank 1 are fixedly installed at the bottom of the base oil tank through the second mounting flange 303. The telescopic tube 2012 is provided so that the oil storage tank 1 and the oil inlet of the base oil tank can be perfectly matched and used.

[0034] Adjust the monitoring position of the oil level monitoring probe by rotating the lifting rod, and extend the oil level monitoring probe into the base oil tank. When the oil level monitoring probe detects that the oil level in the base oil tank has decreased, start the replenishment pump 203 to extract the oil from the storage tank 1 and discharge it into the base oil tank through the oil discharge assembly 2 for replenishment. The internal structure of the one-way oil discharge pipe 202 is designed to achieve one-way oil discharge, with greater resistance to reverse flow, thus achieving a better anti-backflow effect.

[0035] In this embodiment, the oil drain assembly 2, through its oil drain head mechanism 201, achieves excellent positional adaptability via the telescopic tube 2012 and hose 2014. The first mounting flange 2011 can connect to the oil inlet of the base tank of different specifications, the telescopic tube 2012 is length-adjustable, and the hose 2014 has a certain degree of bending performance. Together, these features enable the oil drain end to flexibly match interfaces of different heights and angles, significantly improving the applicability of the equipment in complex installation environments. Simultaneously, the oil level monitoring probe and lifting rod structure inside the feed seat 2013 can monitor the oil level in the tank in real time, and through the replenishment pump 203 and the one-way drain pipe 202, automatic start / stop and anti-backflow functions are achieved, ensuring an intelligent and reliable oil replenishment process.

[0039] The inner wall of the collar 301 is provided with a rubber pad, and the inner wall of the collar 301 is tightly connected to the outer wall of the oil storage tank 1 through the rubber pad.

[0040] In this embodiment, the positioning component 3 is tightly connected to the outer wall of the oil tank 1 via the collar 301, and its height is adjusted by the lifting hydraulic cylinder 302. This allows the second mounting flange 303 to flexibly adapt to different heights and inclinations of the base oil tank bottom. The second mounting flange 303 has multiple mounting holes, supporting various bolt arrangements, further enhancing installation compatibility and structural stability. This component effectively overcomes the installation difficulties caused by inconsistent oil tank bottom structures, ensuring the entire oil replenishment device can be stably installed in different models and guaranteeing sealing and reliability during long-term operation.
