Description

Technical Field

[0001] This utility model belongs to the field of oil sight glasses, and specifically relates to an oil sight glass with a cleaning function. Background Technology

[0002] Centrifugal pumps and compressors are crucial equipment in many areas of industrial production. Centrifugal pumps achieve efficient fluid transport by utilizing the centrifugal force generated by the high-speed rotation of the impeller. They offer advantages such as simple structure, stable and reliable operation, and wide applicability, playing an indispensable role in industries such as water supply, drainage, chemical, and petroleum. They are commonly used fluid transport equipment in industrial production and daily life. Compressors play a core role in air compression, refrigeration systems, and gas transport, ensuring the smooth operation of various processes. Furthermore, during the operation of centrifugal pumps and compressors, the oil sight glass, as a vital component for monitoring the lubricating oil condition, directly affects the operational stability and service life of the equipment.

[0003] However, traditional sight glasses for centrifugal pumps and compressors have revealed many problems that urgently need to be solved in practical applications. Specifically, during long-term use, the lubricating oil oxidizes and deteriorates under the combined effects of dust and high temperatures, gradually producing solid particles and other impurities. These impurities adhere to the inner wall of the sight glass, forming stubborn grease that is difficult to clean, greatly reducing the visibility of the sight glass and making it difficult for operators to clearly and accurately observe the true level of the lubricating oil, easily leading to misjudgments of the equipment's lubrication status.

[0004] Moreover, existing oil sight glasses often lack effective cleaning mechanisms in their design. Once the inner wall is contaminated, it can usually only be cleaned by manual disassembly. This process not only consumes a lot of time and manpower, but may also damage the connection parts of the equipment due to frequent disassembly, thereby affecting the overall stability and sealing of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems of easy contamination and difficulty in cleaning existing oil sight glasses during use, and to propose and design an oil sight glass with a cleaning function. This allows the oil sight glass to clean its inner wall during operation, effectively removing attached oil stains, impurities and other contaminants, so that operators can better monitor the lubricating oil level and ensure that the operating parts of the pump are always in the best lubrication condition.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: an oil sight glass with a cleaning function, comprising a mounting body, one end of which is provided with a device connection part, and the other end of which is equipped with a sight glass. A cleaning hole is provided on the mounting body near the end of the sight glass, and a cleaning component is installed below the cleaning hole. It also includes an operating rod, the end of which can pass through the cleaning hole and be connected to the cleaning component for transmission, and control the cleaning component to perform cleaning operations, so as to effectively remove oil stains, impurities and other contaminants attached to the surface of the sight glass.

[0007] Furthermore, the cleaning component includes a mounting bracket, which is fixedly connected to the mounting body. The mounting bracket is provided with a horizontal rotating shaft, and a rotating sleeve is fitted onto the horizontal rotating shaft. The axis of the rotating sleeve is perpendicular to the sight glass. A gear part and a cleaning part are sequentially arranged on the rotating sleeve along the direction close to the sight glass. A rotating rod is fixedly installed on the cleaning part, and a mirror scraper is provided on the side wall of the rotating rod. A rack is installed on the side wall of the operating rod. When the operating rod extends into the mounting body through the cleaning hole, the rack can mesh with the gear part. As the rack moves up and down with the operating rod, it drives the gear part to rotate in the corresponding direction. Thus, the gear part drives the rotating rod and the mirror scraper fixedly installed on the rotating rod to rotate, thereby cleaning the sight glass.

[0008] Furthermore, a bottom scraper is provided on the side wall of the rotating rod, and the dirt on the inner ring of the mounting body is cleaned by the bottom scraper.

[0009] Furthermore, a limiting block is fixedly installed at the end of the horizontal rotating shaft, and the size of the limiting block is larger than the inner diameter of the rotating sleeve, thereby preventing the rotating sleeve from detaching from the horizontal rotating shaft.

[0010] Furthermore, a plug can be detachably installed on the surface of the cleaning hole, which can be used to seal it in non-clean environments to prevent leaks. Additionally, in scenarios where a plug is not required, the operating rod can be left inside the cleaning hole for extended periods without needing to be removed.

[0011] Furthermore, a pull ring is installed at the end of the operating lever, which allows the operator to easily pull the operating lever.

[0012] Furthermore, the equipment connection part of the installation body is equipped with a sealing sleeve, which can seal the connection position between the installation body and equipment such as centrifugal pumps and compressors.

[0013] Furthermore, the equipment connection part of the main body is provided with external threads, and is connected to equipment such as centrifugal pumps and compressors through the external threads.

[0014] As can be seen from the above technical solution, this utility model has the following advantages: This utility model can directly utilize the meshing transmission of the rack and pinion of the operating lever to convert the up-and-down movement of the operating lever into the rotational movement of the cleaning components. This drives the rotating rod, mirror scraper, and bottom scraper to rotate, thus directionally cleaning oil stains and impurities from the sight glass surface. This achieves large-area coverage of the key observation areas of the sight glass, effectively removing oil stains and ensuring the sight glass remains clear for a long time, guaranteeing the operator's accurate judgment of oil level and quality. Furthermore, the entire operation process requires no professional tools and no disassembly of the sight glass or equipment connections, avoiding the cumbersome process of traditional manual cleaning requiring machine shutdown and disassembly. This significantly reduces maintenance time and labor costs, making it particularly suitable for scenarios with high requirements for production continuity. Attached Figure Description

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides an oil sight glass with a cleaning function, which includes a mounting body 20. The mounting body 20 is made of PTFE rod and machined by a machine tool. An oil inlet 1 extends through the middle of the mounting body 20. One end of the mounting body 20 is configured as a device connection part 3 for mounting with external equipment such as centrifugal pumps and compressors. The outer wall of the device connection part 3 is provided with external threads and fitted with a sealing sleeve 7. Thus, when the mounting body 20 is installed with the external equipment via the external threads, the sealing sleeve 7 enhances the sealing of the connection between the two, preventing lubricating oil leakage and improving the operational safety of the equipment.

[0023] The other end of the mounting body 20 is fixedly mounted with a sight glass 5 using an adhesive or similar method. A cleaning hole 6 is provided on the upper part of the mounting body 20, which radially penetrates the mounting body 20 and connects to the oil inlet 1 and the outside. A cleaning component 2 is installed below the cleaning hole 6. Specifically, in this embodiment, the cleaning component 2 includes a mounting bracket 15. One end of the mounting bracket 15 is fixedly connected to the inner wall of the mounting body 20 using an adhesive or similar method. The other end of the mounting bracket 15 is provided with a horizontal rotating shaft 19, located near the center of the sight glass 5. A rotating sleeve 17 is fitted onto the horizontal rotating shaft 19, allowing the rotating sleeve 17 to rotate freely around the horizontal rotating shaft 19, with the axis of the rotating sleeve 17 perpendicular to the sight glass 5. The rotating sleeve 17 is provided with a gear part 13 and a cleaning part 16 in sequence along the direction close to the sight glass 5. The cleaning part 16 is fixedly mounted with a rotating rod 10. The side wall of the rotating rod 10 is provided with a bottom scraper 12 and a mirror scraper 11, so that the end of the bottom scraper 12 can contact the inner ring of the sight glass 5, and the side of the mirror scraper 11 can contact the surface of the sight glass 5. This ensures that when the bottom scraper 12 and the mirror scraper 11 rotate with the rotating rod 10, the bottom scraper 12 can clean the inner ring of the mounting body 20, and the mirror scraper 11 can clean the surface of the sight glass 5.

[0024] In addition, this utility model also includes an operating lever 14. The end of the operating lever 14 can pass through the cleaning hole 6 and be connected to the cleaning component 2 for transmission, and control the cleaning component 2 to perform cleaning operations to effectively remove oil stains, impurities and other contaminants attached to the surface of the sight glass 5. Specifically, in this embodiment, a rack 9 is installed on the side wall of the operating lever 14. When the operating lever 14 extends into the mounting body 20 through the cleaning hole 6, the rack 9 can mesh with the gear part 13. As the rack 9 moves up and down with the operating lever 14, it drives the gear part 13 to rotate in the corresponding direction. Thus, the gear part 13 drives the rotating rod 10 and the mirror scraper 11 fixedly installed on the rotating rod 10 to rotate, so as to clean the sight glass 5. Furthermore, to ensure that it does not interfere with the rotating rod 10, the width of the operating rod 14 and the rack 9 should be equal to or less than the width of the gear part 13. The thickness of the operating rod 14 should be such that the operating rod 14 can extend into the cleaning hole 6 and be located on the left side of the gear part 13, and can also extend into the cleaning hole 6 and be located on the right side of the gear part 13, so as to ensure that the gear part 13 has a sufficient range of rotation.

[0025] Furthermore, as a preferred embodiment, a pull ring 8 can be installed at the end of the operating rod 14, allowing the operator to easily pull the operating rod 14. After installing the rotating sleeve 17 at the end of the horizontal rotating shaft 19, a limiting block 18 is fixedly installed by means of bonding or other methods, and the size of the limiting block 18 is larger than the inner diameter of the rotating sleeve 17, thereby preventing the rotating sleeve 17 from detaching from the horizontal rotating shaft 19. A plug 4 is detachably installed on the surface of the cleaning hole 6, and can be used to block it in a non-clean environment to prevent leakage. In addition, in some scenarios where the plug 4 is not needed, the operating rod 14 can be left in the cleaning hole 6 for a long time without being removed.

[0026] Based on this, the present invention can directly utilize the meshing transmission between the rack 9 and gear 13 of the operating lever 14 to convert the up-and-down movement of the operating lever 14 into the rotational movement of the cleaning component 2, thereby driving the rotating rod 10, the mirror scraper 11, and the bottom scraper 12 to rotate, so as to perform targeted cleaning of oil stains and impurities on the surface of the sight glass 5, effectively removing oil stains and ensuring that the sight glass 5 remains clear for a long time.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
