Description

Technical Field

[0001] This utility model relates to the field of sampler technology, specifically an adjustable depth sampler for oil tankers. Background Technology

[0002] As a primary means of transporting liquids, the inspection and monitoring of the quality of the oil inside tank trucks is particularly crucial. To ensure that the oil meets quality standards, samples are typically collected for testing before unloading. The depth and location of the sampling directly affect the representativeness of the sample and the validity of the test results. Traditional sampling relies heavily on manual operation, extracting samples from inside the tank truck through simple pipes or cylinders. This process is cumbersome and requires a high level of skill and experience from the operator.

[0003] However, existing sampling devices have many limitations in their structural design, particularly in the lack of effective solutions for adjusting the sampling depth. Most traditional devices can only sample at a fixed depth or a limited number of preset depths, making it difficult to adapt to the diverse needs of different types of tank trucks. Furthermore, traditional samplers generally can only collect samples from a single depth at a time, failing to achieve simultaneous sampling from multiple depths, resulting in low sampling efficiency and hindering a comprehensive assessment of oil quality. At the same time, the adjustment process of traditional samplers is often complex, time-consuming, and labor-intensive, placing a significant burden on on-site personnel and posing inconvenience and safety hazards in practical applications. Therefore, this invention proposes an adjustable depth sampler for tank trucks. Utility Model Content

The sampling frame is also equipped with a limiting component for limiting the gear. By setting the rotating handle and the gear, the length of the depth rod can be adjusted, thereby allowing the sampling depth at one end of the sampling input tube to be flexibly adjusted, facilitating the collection of oil samples at different depths. Furthermore, the sampler is equipped with multiple sampling cylinders, making it easy to collect oil samples from different depths. It is simple, quick, and highly practical.

[0024] 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.

[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution: an adjustable depth sampler for oil tankers, including a sampling frame 1. Multiple detachable sampling cylinders 2 are placed on top of the sampling frame 1. The sampling cylinders 2 are attracted to the metal sampling frame 1 by magnets 201 at their bottom. The magnets 201 ensure the sampling cylinders 2 are securely fixed to the sampling frame 1 and facilitate disassembly and replacement, improving operational convenience. Furthermore, a sampling pump 3 is installed on the top of the sampling frame 1. When changing to different sampling depths, the pump 3 can be used to reverse the flow to drain any residual oil sample from the sampling input pipe 4 and sampling output pipe 5, preventing cross-contamination and ensuring the purity and reliability of the sample.

[0026] In one possible implementation, the sampling pump 3 can be a gear pump with forward and reverse rotation functions. The gear pump is powered by an external rechargeable explosion-proof battery (not shown in the figure). When rotating forward, the gear pump draws oil samples from inside the oil tank and delivers them to the sampling cylinder 2 through the sampling input pipe 4 and the sampling output pipe 5 to complete the sampling. When rotating in reverse, the gear pump discharges the residual oil samples in the sampling input pipe 4 and the sampling output pipe 5 in the opposite direction to ensure the cleanliness of the pipeline.

[0027] One end of the sampling pump 3 is connected to the sampling input pipe 4, and the other end of the sampling pump 3 is connected to the sampling output pipe 5. One end of the sampling input pipe 4 is connected to the depth rod 6. The depth rod 6 is movably mounted on the sampling frame 1. A scale 601 is provided on one side of the depth rod 6, and a toothed groove 602 is provided on the other side. The scale 601 allows the operator to intuitively and accurately understand the length of the depth rod 6, which facilitates the adjustment of the sampling depth as needed, thereby improving the accuracy and repeatability of the operation. A movable gear 7 is installed on the sampling frame 1. The gear 7 meshes with a depth rod 6 with a toothed groove 602. A handle 8 is connected to one side of the gear 7. The sampling frame 1 is also equipped with a limiting member 9 for limiting the gear 7. By driving the gear 7 to rotate through the handle 8, the meshing of the gear 7 with the toothed groove 602 can drive the depth rod 6 to adjust its length in the vertical direction. This makes the depth of one end of the sampling input tube 4 adjustable, thereby meeting the needs of oil sample collection at different depths and improving the efficiency and flexibility of operation. The limiting member 9 ensures the stability of the gear 7 during adjustment. Furthermore, the sampler is equipped with multiple sampling cylinders 2, which can conveniently collect samples at different depths, making it easy to use and highly practical.

[0028] Please refer to the following carefully. Figure 1 and Figure 2 The sampling frame 1 has a telescopic rod 10 fixedly connected to its end. The telescopic rod 10 includes a fixed cylinder 1001 fixed at the edge of the sampling frame 1. A movable rod 1002 is inserted into the fixed cylinder 1001.

[0029] In one possible implementation, the sampling input tube 4 can be a flexible tube, and the sampling output tube 5 can be a metal flexible tube.

[0030] Please refer to the following carefully. Figure 2 and Figure 3 The sampling frame 1 is provided with a support frame 101 for installing the depth rod 6. The depth rod 6 is movably installed inside the support frame 101. One end of the limiting member 9 is movably installed on the sampling frame 1, and the other end of the limiting member 9 is movably installed in the tooth groove of the gear 7.

[0031] Working Process: The operator first places the sampling frame 1 close to the sampling port of the tanker truck. Adjusting the extension length of the movable rod 1002 according to the location of the sampling port ensures the sampling frame 1 is securely positioned at the tanker truck's sampling port. Adjusting the telescopic rod 10 ensures the overall position of the sampling frame 1 is stable and horizontal, providing reliable support for subsequent sampling. Then, rotating the handle 8 causes the gear 7 to mesh with the toothed groove 602 on the side of the depth rod 6, allowing the depth rod 6 to be adjusted vertically within the support frame 101. Observing the scale 601 on the side of the depth rod 6 ensures the sampling input pipe 4 reaches the predetermined sampling depth inside the tanker. After depth adjustment, the reverse function of the sampling pump 3 is activated to empty the oil sample from the sampling input pipe 4 and the sampling output pipe 5, ensuring the pipeline is clean. Subsequently, the sampling pump 3 is switched to the forward rotation state, and the sampling pump 3 begins to draw oil samples from the preset depth in the oil tank. The oil samples enter the sampling pump 3 through the sampling input pipe 4, and are then transported to the corresponding sampling cylinder 2 through the sampling output pipe 5 to complete the sampling.

[0032] If multiple oil samples need to be collected, the operator can repeatedly rotate the handle 8 to adjust the depth lever 6 to the new sampling depth, and then collect oil samples at different depths in sequence. After sampling, turn off the sampling pump 3 and disassemble the sampling cylinder 2 for sample preservation and analysis.
