Description

A lubricating oil sampling device for production Technical Field

[0001] This utility model relates to the field of lubricating oil sampling technology, and in particular to a lubricating oil sampling device for production. Background Technology

[0002] In the existing technology, lubricating oil is a lubricant used in various types of automobiles and mechanical equipment to reduce friction. During the production process, lubricating oil samples need to be taken to test its quality.

[0003] As shown in the reference case "A Leak-Proof Sampling Device for Lubricating Oil Production" (Announcement No. CN217930927U), by setting up an upper cylinder and a lower cylinder, the lubricating oil can be sampled in layers by controlling the movement depth. By connecting the upper cylinder and the lower cylinder to the cover plate and the intermediate shell respectively through threads, the sealing performance during the sampling process can be improved.

[0004] While existing technologies can achieve stratified extraction, the extracted samples are still collected inside the same sampling tube and cannot be physically isolated or stored independently. This is inconvenient when it is necessary to conduct independent testing or comparative analysis of samples from different layers, and poses the risks of cumbersome operation and cross-contamination.

[0005] Therefore, a lubricating oil sampling device for production is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a lubricating oil sampling device for production in order to solve the above-mentioned problems. It improves the existing technology, which, although it can achieve stratified extraction, still collects multiple samples inside the same sampling cylinder, making it impossible to physically isolate or store them independently. This is inconvenient when it is necessary to conduct independent testing or comparative analysis of samples from different layers, and poses problems such as cumbersome operation and risk of cross-contamination.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a lubricating oil sampling device for production, comprising: a sampling chamber, on one side of which a sampling head is fixedly installed; and a switching sampling mechanism, which is disposed inside the sampling chamber for rapid sampling of different samples. The switching sampling mechanism includes multiple sample containers disposed inside the sampling chamber. A driving component is disposed on one side of the sampling chamber, and a cleaning component is disposed on one side of the sampling head. The driving component controls the rapid switching connection between the sampling head and the multiple sample containers, allowing the sampling head to selectively introduce lubricating oil samples into different containers as needed during a single sampling operation. This enables independent separate collection of multiple batches or stratified samples, avoiding mixing of samples from different layers. Furthermore, the sampling head is connected to the cleaning component, which allows for immediate cleaning of the sampling head between switching between different sample containers, preventing residual lubricating oil or impurities from being carried into the next sample, further improving sampling purity and avoiding cross-contamination.

[0008] Preferably, the driving assembly includes an inlet fixedly installed on one side of the sample container, a connecting tube provided on one side of the inlet, the other end of the connecting tube being fixedly connected to a sampling head, a driving rod fixedly installed on the surface of the connecting tube, the other end of the driving rod extending out of the surface of the sampling chamber, the driving rod being slidably connected to the surface of the sampling chamber, a spring fixedly installed on one side of the driving rod, the other end of the spring being fixedly connected to the inner wall of the sampling chamber, and a one-way rotating plate rotatably installed inside the inlet. When switching samples, the driving rod is pushed to slide the connecting tube outward and separate it from the current inlet. During the separation process, the one-way rotating plate inside the inlet automatically rotates to close the inlet outlet channel, achieving rapid sealing. Subsequently, another sample container can be moved to the corresponding position of the connecting tube to achieve a new sampling path connection, enabling rapid switching between multiple sets of sample containers.

[0009] Preferably, the drive assembly further includes an air pump fixedly installed on the surface of the sampling chamber. The output end of the air pump extends into the interior of the sampling chamber, and a connecting hose is fixedly connected to the output end of the air pump. A connecting pipe is fixedly installed on the surface of the sample container. During the switching operation, when the connecting pipe is connected to the inlet and the sample container is in place, the connecting hose will be inserted synchronously and aligned with the connecting pipe. At this time, a closed loop is formed between the air pump, the connecting pipe, and the sampling head. After the air pump is started, the external lubricating oil sample can be drawn into the corresponding sample container through this passage.

[0010] Preferably, the inlet opening is funnel-shaped, and the connecting end of the connecting tube to the inlet is conical. When the connecting tube and the inlet are in contact, the connecting tube and the inlet are fitted with a conical guide structure, which can automatically align the insertion direction during the sliding connection process and achieve rapid positioning.

[0011] Preferably, a drive plate is rotatably mounted on one side of the sampling chamber, and multiple sample containers are fixedly connected to the surface of the drive plate. When changing samples, the drive plate can be rotated to drive the connected sample containers to move synchronously, and the target container can be moved to the sampling channel position where the connecting tube is located in sequence to complete the docking switch.

[0012] Preferably, the cleaning assembly includes a storage tank fixedly installed inside the sampling chamber. The output end of the storage tank is fixedly connected to the sampling head through an output pipe. The storage tank contains cleaning fluid. When cleaning is required, the sampling chamber can be opened, the connecting pipe can be closed, and the storage tank can input the internal cleaning fluid into the sampling head for cleaning.

[0013] Preferably, the cleaning assembly further includes a one-way pump fixedly installed on the surface of the output pipe, and a pull rod fixedly installed on the surface of the sampling chamber. During cleaning, the one-way pump is activated to drive the cleaning fluid inside the storage tank to be input into the output pipe. The cleaning fluid flows into the sampling head for rinsing, thus completing the cleaning process.

[0014] The beneficial effects of this utility model are:

[0015] 1. The drive component controls the rapid switching connection between the sampling head and multiple sample containers, allowing for selective introduction of lubricating oil samples into different containers as needed, avoiding mixing of different samples. In addition, the sampling head is connected to a cleaning component, which can clean the sampling head in real time between switching between different sample containers, preventing residual lubricating oil or impurities from being carried into the next sample, further improving the purity of the sample and avoiding cross-contamination.

[0016] 2. The storage tank contains cleaning solution. When cleaning is required, the sampling chamber can be opened and the connecting pipe closed. During cleaning, the one-way pump is started to drive the cleaning solution inside the storage tank to the output pipe. The cleaning solution flows into the sampling head for rinsing, thus completing the cleaning process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In specific implementation: As shown in Figures 1-4, a lubricating oil sampling device for production includes: a sampling chamber 1, with a sampling head 2 fixedly installed on one side of the sampling chamber 1; and a switching sampling mechanism 3, which is set inside the sampling chamber 1 for rapid sampling of different samples. The switching sampling mechanism 3 includes multiple sample containers 31 set inside the sampling chamber 1, a driving component 32 set on one side of the sampling chamber 1, and a cleaning component 33 set on one side of the sampling head 2. The driving component 32 controls the rapid switching connection between the sampling head 2 and the multiple sample containers 31, so that the sampling head 2 can selectively introduce lubricating oil samples into different containers as needed in one sampling operation, thereby realizing the independent separation and collection of multiple batches or layered samples, avoiding the mixing of samples from different layers. In addition, the sampling head 2 is connected to the cleaning component 33, which can clean the sampling head 2 in time between switching between different sample containers 31 to prevent residual lubricating oil or impurities from being carried into the next sample, further improving the sampling purity and avoiding cross-contamination.

[0024] The lubricating oil sampling device mainly includes basic components such as sampling chamber 1, sampling head 2, and sample collection assembly. The drive assembly 32 can quickly switch the sampling storage space, and the cleaning assembly 33 is used to quickly rinse and clean the sampling head 2. Therefore, it does not affect the sampling accuracy, sampling stability and structural strength of the device itself.

[0025] As shown in Figures 2, 3, and 4, the drive assembly 32 includes an inlet 321 fixedly installed on one side of the sample container 31. A connecting tube 323 is provided on one side of the inlet 321, and the other end of the connecting tube 323 is fixedly connected to the sampling head 2. A drive rod 324 is fixedly installed on the surface of the connecting tube 323, and the other end of the drive rod 324 extends out of the surface of the sampling chamber 1. The drive rod 324 is slidably connected to the surface of the sampling chamber 1. A spring 325 is fixedly installed on one side of the drive rod 324, and the other end of the spring 325 is fixedly connected to the inner wall of the sampling chamber 1. A one-way rotating plate 322 is rotatably installed inside the inlet 321. The connecting tube 323 is a corrugated telescopic tube. When switching samples, the drive rod 324 is pushed, causing the connecting tube 323 to slide outward and separate from the current inlet 321. During the separation process, the one-way rotating plate 322 inside the inlet 321 automatically rotates, closing the outlet channel of the inlet 321 to achieve rapid sealing. Then, another sample container 31 can be moved to the corresponding position of the connecting tube 323. This system enables new sampling path connections and allows for rapid switching between multiple sample containers 31, suitable for collecting lubricating oil samples of various specifications. The drive assembly 32 also includes an air pump 326 fixedly installed on the surface of the sampling chamber 1. The output end of the air pump 326 extends into the interior of the sampling chamber 1, and a connecting hose 327 is fixedly connected to the output end of the air pump 326. A connecting pipe 328 is fixedly installed on the surface of the sample container 31. The connecting pipe 328 has an inwardly opening one-way plate inside. This one-way plate is used to be opened when the connecting hose 327 is inserted and kept closed when not connected. During the switching operation, when the connecting pipe 323 is connected to the inlet 321 and the sample container 31 is in place, the connecting hose 327 will be inserted synchronously and aligned with the connecting pipe 328. At this time, a closed loop is formed between the air pump 326, the connecting pipe 323, and the sampling head 2. After the air pump 326 is started, the external lubricating oil sample can be drawn into the corresponding sample container 31 through this passage to achieve negative pressure sampling operation.

[0026] The opening of the inlet 321 is set in a funnel shape, and the connection end of the connecting tube 323 and the inlet 321 is set in a conical shape. When the connecting tube 323 and the inlet 321 are in contact with each other, the connecting tube 323 and the inlet 321 are matched with a conical guide structure, which can automatically align the insertion direction during the sliding connection process and achieve rapid positioning. A drive plate 329 is rotatably installed on one side of the sampling chamber 1. Multiple sample containers 31 are fixedly connected to the surface of the drive plate 329. The multiple sample containers 31 are arranged in a ring along the surface of the drive plate 329. When changing samples, the connected sample containers 31 can be driven to move synchronously by rotating the drive plate 329, and the target container is moved to the sampling channel position where the connecting tube 323 is located in sequence to complete the docking and switching.

[0027] As shown in Figures 2, 3, and 4, the cleaning assembly 33 includes a storage tank 331 fixedly installed inside the sampling chamber 1. The output end of the storage tank 331 is fixedly connected to the sampling head 2 via an output pipe 332. The storage tank 331 stores cleaning fluid. When cleaning is required, the sampling chamber 1 can be opened and the connecting pipe 323 can be closed. The storage tank 331 will then input the cleaning fluid into the sampling head 2 for cleaning. The cleaning assembly 33 also includes a one-way pump 333 fixedly installed on the surface of the output pipe 332. A pull rod 11 is fixedly installed on the surface of the sampling chamber 1. During cleaning, the one-way pump 333 is activated to drive the cleaning fluid inside the storage tank 331 to be input into the output pipe 332. The cleaning fluid flows into the sampling head 2 for rinsing, completing the cleaning process.

[0028] In use, when switching samples, the drive rod 324 is pushed to slide the connecting tube 323 outward, separating it from the current inlet 321. During separation, the one-way rotating plate 322 inside the inlet 321 automatically rotates, closing the outlet channel of the inlet 321 for rapid sealing. Then, another sample container 31 can be moved to the corresponding position of the connecting tube 323, establishing a new sampling path. This allows for rapid switching between multiple sample containers 31. During the switching operation, once the connecting tube 323 is connected to the inlet 321 and the sample container 31 is in place, the connecting hose 327 is simultaneously inserted and aligned with the connecting tube 328. At this time, the suction pump... A closed loop is formed between 326, connecting pipe 323, and sampling head 2. After the suction pump 326 is started, the external lubricating oil sample can be drawn into the corresponding sample container 31 through this passage to realize negative pressure sampling operation. Multiple sample containers 31 are distributed in a ring along the surface of the drive plate 329. When changing samples, the rotation of the drive plate 329 can drive the connected sample containers 31 to move synchronously, and the target container is moved to the sampling channel position where the connecting pipe 323 is located in sequence to complete the docking switch. During cleaning, the one-way pump 333 is started to drive the cleaning fluid inside the storage tank 331 to be input into the output pipe 332. The cleaning fluid flows into the sampling head 2 for rinsing, completing the cleaning process.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
