Technical Field
[0001] This utility model relates to the field of oil sampling technology, specifically to a sampling device. Background Technology
[0002] When receiving fuel or liquid cargo from tanker trucks, gas stations typically take samples to ensure the quality and safety of the cargo. The sampling process aims to ensure that the quality of the fuel or liquid cargo meets relevant standards and requirements to protect customer safety and comply with government and regulatory requirements. Sampling usually takes place before or during unloading of the tanker truck arriving at the gas station. Using a tanker truck sampler or other suitable sampling equipment, samples are collected from the appropriate ports, pipes, or other suitable locations on the tanker truck. After sampling, the samples are typically sealed, labeled, and recorded to maintain their integrity and traceability. The sealed samples are usually sent to a laboratory for analysis to test their quality, purity, and safety, confirming that the cargo meets quality standards.
[0003] Before unloading oil from tank trucks carrying petrochemical products, it is necessary to sample and test the oil in the tank. This requires a sampler, which is connected to the unloading port of the tank truck. During oil sampling, samples are often taken from different layers of oil in the tank. However, traditional samplers need to be disassembled after sampling one layer of oil, and the oil needs to be drained for a period of time before the sampler can be reassembled to continue sampling. This process needs to be repeated many times to collect all the oil samples. This sampling method is time-consuming, labor-intensive, and inefficient, and it can also interfere with the unloading efficiency of the tank truck. Utility Model Content

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a sampling device, comprising:
[0007] A sampler, comprising a base, a connector, and a drain component, wherein the base has a cavity, and the connector and drain component are both mounted on the base and communicate with the cavity; and...
[0008] The docking mechanism includes a connector and a docking component. The connector is mounted on the base and corresponds to the opening at one end of the cavity. The docking component has a docking tube that can be detachably connected to the base via the connector, so that the docking tube can be connected to or separated from the opening at one end of the cavity.
[0009] In some embodiments, the connector includes a sleeve and two clamping portions.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0023] To address the technical problem of low sampling efficiency caused by the need for multiple disassembly and reassembly of the sampler in existing technologies to complete multiple oil samplings, this utility model provides a sampling device that can sample oil during the transportation of oil from tank trucks to storage tanks, thereby improving sampling efficiency.
[0024] Please see Figures 1-3 , Figures 1-3A sampling device according to one embodiment of the present invention includes a sampler 1 and a docking mechanism 2. The sampler 1 includes a base 11, a connector 12, and a drain component 13. The base 11 has a cavity. The connector 12 and the drain component 13 are both installed on the base 11 and communicate with the cavity. The docking mechanism 2 includes a connector 21 and a docking component 22. The connector 21 is installed on the base 11 and corresponds to the opening at one end of the cavity. The docking component 22 has a docking tube 221. The docking tube 221 can be detachably connected to the base 11 via the connector 21 so that the docking tube 221 can communicate with or separate from the opening at one end of the cavity.
[0025] In actual use, the unloading port of each tanker truck is connected to a docking component 22 via an oil guide pipe. The docking connector 12 of the sampler 1 is inserted into the oil inlet of the storage tank. When the tanker truck needs to unload oil into the storage tank, the docking tube 221 of the docking component 22 can be inserted into the opening at one end of the base 11. The connector 21 is used to fix the docking tube 221 to the base. Then, by opening the draining component 13 at intervals, the oil transported by the tanker truck to the storage tank can be unloaded, thus completing the sampling of each oil layer in the tanker truck.
[0026] It should be noted that, in one embodiment, the connector 21 includes a sleeve 211 and two clamping parts 212. The sleeve 211 is mounted on the base 11, and the opening at one end of the sleeve 211 corresponds to the opening at one end of the cavity. Both clamping parts 212 are mounted on the sleeve 211, and a clamping space is formed between the two clamping parts 212. The squeezing surfaces of the two clamping parts 212 are close to or far apart, which can adjust the size of the clamping space.
[0027] It is understandable that when the docking tube 221 is inserted into the clamping space and extends into the opening at one end of the cavity, the docking tube 221 can be fixed by the squeezing surfaces of the two clamping parts 212 approaching each other; wherein, the outer diameter of the docking tube 221 is the same as the inner diameter of the opening at one end of the cavity, and a sealing ring is provided on the outer wall of the docking tube 221, which can improve the sealing performance of the connection between the docking tube 221 and the seat body and prevent oil leakage.
[0028] Based on the above scheme, in one embodiment, the clamping part 212 includes an adjusting screw 2121, a pressure plate 2122, and a guide rod 2123. The adjusting screw 2121 is threadedly rotatably connected to a threaded hole on the sleeve 211, and one end is rotatably connected to the pressure plate 2122 disposed in the sleeve 211. At least one of the guide rods 2123 passes through a through hole on the sleeve 211 and is connected to the pressure plate 2122.
[0029] It is understood that by rotating the two adjusting screws 2121, the two pressure plates 2122 can be driven to move closer or further apart. When the contact surfaces of the two pressure plates 2122 are pressed against the docking tube 221, the docking tube 221 can be fixed in the clamping space.
[0030] Based on the above scheme, in order to improve the stability of fixing the docking tube 221, the pressure plate 2122 is semi-circular, and a sealing block is provided on the contact surface of the two pressure plates 2122 that abut against the side wall of the docking tube 221; wherein, the sealing block is an elastic rubber pad.
[0031] It should be noted that, in one embodiment, when the two pressure plates 2122 abut against the sidewall of the docking tube 221, a compression gap is formed between the opposite sides of the two pressure plates 2122. Furthermore, the connector 21 also includes two clamping parts 213, both of which are mounted on the sleeve 211, and the two clamping parts 213 can abut against the outer wall of the docking tube 221 through the two compression gaps.
[0032] It should be noted that the pressing part 213 is not limited to a specific structure, as long as it can extend into the compression gap and abut against the docking tube 221, no other limitations are made here.
[0033] In one embodiment, the clamping part 213 includes an abutment block 2131 and a handle 2132. The abutment block 2131 is rotatably mounted on the sleeve 211. One end of the handle 2132 is fixedly connected to the abutment block 2131. When the abutment block 2131 rotates, the abutment surface of the abutment block 2131 can extend into the compression gap and abut against the side wall of the docking insertion tube 221.
[0034] Understandably, the operator drives the abutment block 2131 to rotate by turning the handle 2132, so that the protrusion of the abutment block 2131 extends into the compression gap and abuts against the outer wall of the docking tube 221.
[0035] It should be noted that, in one embodiment, the draining component 13 includes an observation tube 131, a rotary joint 132, a liquid guide tube 133, and a drain valve 134. One end of the observation tube 131 is connected to the seat and communicates with the cavity. The fixed end of the rotary joint 132 is connected to the other end of the observation tube 131. One end of the liquid guide tube 133 is connected to the movable end of the rotary joint 132. The other end of the liquid guide tube 133 is connected to the drain valve 134.
[0036] The liquid guide tube 133 is L-shaped and can rotate 360° to adjust the angle of the discharge valve 134. In addition, the observation tube 131 can be made of transparent plastic tube.
[0037] In one embodiment, the observation tube 131 is made of an alloy tube and is provided with a glass observation window. The observation window allows for easy observation of the oil's color to obtain information about the oil's appearance quality, which helps determine whether the oil meets the requirements or has any abnormalities.
[0038] Based on the above scheme, the docking component 22 further includes a control valve 222 and an oil supply pipe 223. One port of the control valve 222 is connected to the docking insertion pipe 221, and the other port of the control valve 222 is connected to the oil supply pipe 223. At least one sealing ring is sleeved on the outer wall of the oil supply pipe 223.
[0039] It is understandable that the unloading port of the tanker truck is connected to the oil delivery pipe 223 via an oil guide pipe. Specifically, the oil guide pipe is a flexible hose, and the oil delivery pipe 223 can be inserted inside the flexible hose and fixed to the oil guide pipe and the oil delivery pipe 223 by a clamp.
[0040] Based on the above scheme, a temperature sensor is provided inside the cavity of the seat 11, and a display is provided on the outer wall of the seat 11. The temperature sensor is electrically connected to the display, and the display screen is used to display the oil temperature, which is convenient for staff to detect the oil temperature.
[0041] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
