Description

Technical Field

[0001] The utility model relates to the technical field of thin oil stations, in particular to a thin oil station with a double oil level protection device. Background Art

[0002] The oil station is the core equipment of the oil circulation lubrication system. Its primary function is to force lubricating oil to the frictional parts of the machine, ensuring normal operation and extending its service life. The oil station's main functions include: 1. Lubrication: Forming an oil film between moving machine parts reduces friction and wear. It also flushes the frictional parts, removing frictional heat, ensuring normal operation and extending the machine's service life. 2. Cooling: Using an oil cooler to cool the lubricating oil prevents overheating of parts due to frictional heat. 3. Filtration: Using filters to remove impurities and metal particles from the lubricating oil, maintaining oil cleanliness.

[0003] However, the existing thin oil station is equipped with a liquid level switch. The sensing rod of this liquid level switch contains a yellow wax tube and wiring. The yellow wax tube and wiring are easily aged due to long-term immersion in oil, which will cause the liquid level switch signal to false alarm and cause unnecessary equipment failure. If a stainless steel liquid level gauge is newly installed, it may be necessary to open an opening in the thin oil station to insert the stainless steel liquid level gauge into the liquid, which is very inconvenient to install. At the same time, when the liquid level gauge is removed and replaced, the hole needs to be sealed to prevent oil leakage, which is not convenient for disassembly and replacement of the liquid level gauge.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a thin oil station with a double oil level protection device, including: a connecting component 2, one end of the connecting component 2 is connected to one end of the oil tank drain pipe 4, the other end of the connecting component 2 is provided with a valve 3, and the top of the connecting component 2 is provided with a liquid level measuring component 1.

[0023] The liquid level measurement assembly 1 includes: a galvanized pipe 12, the top of the galvanized pipe 12 is connected to the top of the liquid level gauge 11 through a flange, the probe of the liquid level gauge 11 is located in the galvanized pipe 12, the outer side of the bottom end of the galvanized pipe 12 is fixedly connected to the inner ring of the sealing ring 13, the inner wall of the bottom end of the galvanized pipe 12 is fixedly connected to the two ends of the fixed plate 15, and the bottom of the fixed plate 15 is fixedly connected to the top of the ejector pin 14.

[0024] Furthermore, most of the dilute oil stations have an oil tank drain pipe 4 on the side of the mailbox, and the galvanized pipe 12 is connected to the oil tank drain pipe 4 through a tee pipe 210, so that the oil in the oil tank will enter the galvanized pipe 12. According to the principle of communicating vessels, the liquid level in the galvanized pipe 12 is the same as the liquid level in the oil tank. In this way, the liquid level in the galvanized pipe 12 can be measured by the liquid level gauge 11 to know the liquid level in the oil tank. In this way, the liquid level gauge 11 can measure the liquid level in the mailbox without opening the dilute oil station during installation, which is more convenient to install. At the same time, the liquid level gauge 11 can be made of stainless steel, which avoids oil immersion and aging of the line and false alarms.

[0025] The connection assembly 2 includes a tee 210 having a first connection port 21, a second connection port 23, and a third connection port 28. The first connection port 21 is threadedly connected to one end of the valve 3. The third connection port 28 is threadedly connected to one end of the oil tank drain pipe 4. The second connection port 23 is threadedly connected to the bottom end of the galvanized pipe 12. An annular mounting groove 24 is defined at the top of the second connection port 23. A sealing ring 26 is installed within the annular mounting groove 24. The sealing ring 26 is located between the top of the second connection port 23 and the bottom of the sealing ring 13. A partition 25 is fixedly provided on the inner wall of the second connection port 23. A through hole 27 is defined in the middle of the partition 25. The inner wall of the second connection port 23 is also fixedly connected to both ends of a support plate 29. The inner portion of the support plate 29 is slidably sleeved onto the side of the guide rod 211. The top end of the guide rod 211 is fixedly connected to the bottom end of the plug body 22 . A return spring 212 is provided between the plug body 22 and the support plate 29 . The inner ring of the return spring 212 is slidably sleeved on the side of the guide rod 211 .

[0026] Furthermore, when the galvanized pipe 12 is threadedly connected to the second connection port 23, the galvanized pipe 12 drives the fixing plate 15 and the ejector pin 14 to move downward, so that the ejector pin 14 pushes the plug body 22 to move toward the support plate 29, thereby causing the plug body 22 to disengage from the through hole 27. After the plug body 22 is sealed, oil enters the galvanized pipe 12 from the through hole 27; when the galvanized pipe 12 is disassembled and cleaned, the ejector pin 14 disengages from the plug body 22. At this time, the return spring 212 pushes the plug body 22 to move toward the through hole 27, so that the plug body 22 forms a seal on the through hole 27, thereby preventing the oil from flowing out. After the galvanized pipe 12 and the liquid level gauge 11 are disassembled, the second connection port 23 is automatically sealed, and there is no need to manually seal the disassembly port, making the disassembly and replacement of the galvanized pipe 12 and the liquid level gauge 11 more convenient.

[0027] Working principle: When in use, most of the mailboxes in the dilute oil stations are provided with an oil tank drain pipe 4 on the side, and the galvanized pipe 12 is connected to the oil tank drain pipe 4 through a tee pipe 210, so that the oil in the oil tank will enter the galvanized pipe 12. According to the principle of communicating vessels, the liquid level in the galvanized pipe 12 is the same as the liquid level in the oil tank. In this way, the liquid level in the galvanized pipe 12 can be measured by the liquid level gauge 11 to know the liquid level in the oil tank. In this way, the liquid level gauge 11 does not need to be opened on the dilute oil station during installation to measure the liquid level in the mailbox, which is more convenient to install. At the same time, the liquid level gauge 11 can be made of stainless steel, which avoids oil immersion and aging of the line and false alarms.

[0028] When the galvanized pipe 12 is threadedly connected to the second connection port 23, the galvanized pipe 12 drives the fixing plate 15 and the ejector pin 14 to move downward, so that the ejector pin 14 pushes the plug body 22 to move toward the support plate 29, thereby causing the plug body 22 to disengage from the through hole 27. After the plug body 22 is sealed, oil enters the galvanized pipe 12 from the through hole 27; when the galvanized pipe 12 is disassembled and cleaned, the ejector pin 14 disengages from the plug body 22. At this time, the return spring 212 pushes the plug body 22 to move toward the through hole 27, so that the plug body 22 forms a seal on the through hole 27, thereby preventing the oil from flowing out. After the galvanized pipe 12 and the liquid level gauge 11 are disassembled, the second connection port 23 is automatically sealed, and there is no need to manually seal the disassembly port, making the disassembly and replacement of the galvanized pipe 12 and the liquid level gauge 11 more convenient.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
