Description

Technical Field

[0001] This utility model relates to a lubricating oil emulsification monitor, belonging to the field of lubricating oil monitoring technology. Background Technology

[0002] Existing lubricating oil emulsification monitoring technologies have significant drawbacks. Traditional monitoring devices employ an open-structure design, with their observation windows directly exposed to the high-temperature, high-oil-mist environment inside the cylinder. This not only makes the camera lens susceptible to oil contamination, affecting image clarity, but also makes it prone to mechanical vibration damaging precision components, resulting in a high equipment failure rate. Furthermore, the monitoring process relies on manual inspection, making it impossible to capture the accumulation of tiny bubbles in the early stages of lubricating oil emulsification in real time, often missing the optimal maintenance window. Therefore, a lubricating oil emulsification monitor is proposed. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a lubricating oil emulsification monitor to realize real-time monitoring of the emulsification state of lubricating oil.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a lubricating oil emulsification monitor, comprising:

[0005] A ring sleeve, which is mounted on the hydraulic cylinder;

[0006] An observation window is installed on the hydraulic cylinder and is located inside the fixing ring.

[0007] A protective cover, which is mounted on a ring sleeve, and a monitoring chamber is provided inside the protective cover;

[0008] The monitoring cavity contains a fixed camera with its camera lens facing the observation window, and a supplementary lighting component is installed inside the monitoring cavity.

[0009] Preferably, the protective cover has symmetrically arranged rotating grooves on its side wall, a rotating rod is arranged inside the rotating groove, the middle part of the rotating rod is rotatably connected to the rotating groove, a locking block is arranged on the inner wall of one end of the rotating rod, and a spring is arranged between the other end of the rotating rod and the groove wall of the rotating groove.

[0010] The outer wall of the ring sleeve is provided with a slot for the card block to engage.

[0011] Preferably, the outer wall of the rotating rod near the spring is provided with anti-slip texture.

[0012] Preferably, the supplementary lighting component includes:

[0013] The light trough is located inside the monitoring cavity and is ring-shaped, fitting around the camera.

[0014] A light panel is disposed inside a light trough, and multiple LED beads are evenly distributed on the surface of the light panel.

[0015] Preferably, a light-diffusing plate is fixed at the annular opening of the lamp trough.

[0016] Preferably, the protective cover has a placement cavity inside, and a control module is installed inside the placement cavity. The control module is electrically connected to the camera and the supplementary lighting component. The placement cavity also has a battery for providing power to the camera, the supplementary lighting component and the control module.

[0017] Preferably, the surface of the protective cover is provided with heat dissipation holes to dissipate heat from the placement cavity.

[0018] Preferably, the camera is fixedly connected to the inside of the monitoring cavity by bolts, and the rear end of the camera penetrates the side wall of the monitoring cavity and extends into the interior of the placement cavity.

[0019] Preferably, the end face of the ring is provided with a sealing gasket, and the protective cover is provided with a pressing surface;

[0020] After the protective cover is installed inside the ring, the pressing surface presses against the sealing gasket.

[0021] Preferably, the ring is fixedly connected to the inside of the cylinder by bolts.

[0022] Compared with existing technologies:

[0023] 1. This utility model adjusts the brightness inside the monitoring cavity by activating the supplementary lighting component. The camera starts to continuously collect dynamic images of the lubricating oil through the observation window. When the oil emulsifies, the image analysis algorithm immediately identifies the abnormal features and triggers the alarm system to notify maintenance personnel. The entire monitoring process is carried out in a closed environment, effectively avoiding the influence of oil mist and mechanical vibration on the monitoring equipment and realizing real-time monitoring of the emulsification state.

[0024] 2. This utility model utilizes a mechanism where pressing the anti-slip textured end of the rotating rod overcomes the spring's preload, causing the locking block to disengage from the ring's groove and release the lock. The protective cover can then be easily removed by gently pushing it along the ring's axis, exposing the observation window for cleaning. Installation is reversed: aligning the protective cover with the ring and inserting it, the locking block automatically engages with the spring force, completing a quick lock. This mechanical self-locking structure eliminates the need for tool disassembly during maintenance, allowing for single-handed installation and removal of the protective cover, thus improving equipment maintenance efficiency.

[0041] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0042] Example 1

[0043] like Figures 1-7As shown in this embodiment, a lubricating oil emulsification monitor is provided, including a ring sleeve 1 and an observation window 2. The ring sleeve 1 is installed on the oil cylinder by bolts; the observation window 2 is installed on the oil cylinder and is located inside the fixed ring sleeve 1; a protective cover 3 is provided on the ring sleeve 1, and a monitoring cavity 301 is provided inside the protective cover 3; wherein, a camera 4 for collecting images of lubricating oil emulsification is fixed inside the monitoring cavity 301, the camera of the camera 4 is facing the observation window 2, and a supplementary lighting component 5 is provided inside the monitoring cavity 301.

[0044] A sealing gasket 10 is provided on the end face of the ring sleeve 1, and a pressing surface 305 is provided on the protective cover 3;

[0045] After the protective cover 3 is installed inside the ring sleeve 1, the pressing surface 305 is pressed onto the sealing gasket 10 to achieve effective sealing of the monitoring cavity 301.

[0046] Work process:

[0047] During installation, the ring 1 is first fixed to the designated position on the oil cylinder with bolts. Then, the protective cover 3 is inserted into the ring, and its pressing surface 305 is aligned with the sealing gasket 10, so that the sealing gasket 10 seals the monitoring cavity 301. The supplementary lighting component 5 is activated to adjust the brightness inside the monitoring cavity 301, and the camera 4 begins to continuously collect dynamic images of the lubricating oil through the observation window 2. When emulsification occurs in the oil, the image analysis algorithm immediately identifies abnormal features (such as milky white turbidity and bubble aggregation), triggering the alarm system to notify maintenance personnel. The entire monitoring process is carried out in a closed environment, effectively avoiding the influence of oil mist and mechanical vibration on the monitoring equipment, and realizing real-time monitoring of the emulsification state.

[0048] Example 2

[0049] like Figures 1-4 As shown, based on Embodiment 1, in this embodiment, in order to facilitate the disassembly of the protective cover 3 and the cleaning of the observation window 2, a rotating groove 302 is symmetrically arranged on the side wall of the protective cover 3. A rotating rod 6 is arranged inside the rotating groove 302. The middle part of the rotating rod 6 is rotatably connected to the rotating groove 302. A locking block 601 is arranged on the inner wall of one end of the rotating rod 6. A spring 7 is arranged between the other end of the rotating rod 6 and the groove wall of the rotating groove 302.

[0050] Among them, the outer wall of the ring 1 is provided with a slot 101 for the card block 601 to be engaged.

[0051] The outer wall of the rotating rod 6 near the spring 7 has anti-slip texture.

[0052] Work process:

[0053] When the protective cover 3 needs to be removed for maintenance, the operator presses the anti-slip textured end of the rotating rod 6. The rotating rod 6 overcomes the preload of the spring 7, causing the locking block 601 to disengage from the slot 101 of the ring sleeve 1, thus releasing the locking state. The protective cover 3 can then be removed by gently pushing it along the axial direction of the ring sleeve 1, exposing the observation window 2 for cleaning. During installation, the operation is reversed: after aligning the protective cover 3 with the ring sleeve 1 and inserting it, the locking block 601 automatically engages with the slot 101 under the elastic force of the spring 7, completing a quick lock. This mechanical self-locking structure enables tool-free maintenance, ensuring that the installation and removal of the protective cover can be completed with one hand, improving equipment maintenance efficiency.

[0054] Example 3

[0055] like Figure 3 , Figures 5-7 As shown, based on the above embodiments, in this embodiment, the supplementary lighting component 5 includes a lamp groove 501, which is opened inside the monitoring cavity 301 and is ring-shaped and fitted around the camera 4; a lamp plate 502 is provided inside the lamp groove 501, and multiple lamp beads are evenly distributed on the surface of the lamp plate 502; a light-diffusing plate 503 is fixed at the annular opening of the lamp groove 501.

[0056] The protective cover 3 has a placement cavity 303 inside, and a control module 8 is installed inside the placement cavity 303. The control module 8 is electrically connected to the camera 4 and the supplementary lighting component 5. The control module 8 is equipped with a communication module. The placement cavity 303 is also equipped with a battery 9 for providing power to the camera 4, the supplementary lighting component 5 and the control module 8. The battery 9 can be rechargeable and can be equipped with a charging port. The battery 9 can be charged through the charging port to keep the battery 9 fully charged.

[0057] Work process:

[0058] Camera 4 begins to continuously capture dynamic images of the lubricating oil through observation window 2. The image data is sent to the cloud platform via the wireless module of control module 8. When the oil emulsifies, the image analysis algorithm immediately identifies abnormal features (such as milky white turbidity and bubble aggregation), triggers the alarm system to notify maintenance personnel, and stores current and historical images for fault analysis.

[0059] The protective cover 3 has heat dissipation holes 304 on its surface, which connect the placement cavity 303 to the outside and are used to dissipate the heat inside the placement cavity 303.

[0060] The camera 4 is fixedly connected to the inside of the monitoring cavity 301 by bolts, and the rear end of the camera 4 penetrates the side wall of the monitoring cavity 301 and extends into the inside of the placement cavity 303.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model.
