Description

Technical Field

[0001] This utility model relates to the field of petroleum testing and sampling technology, specifically to a petroleum testing and sampling device. Background Technology

[0002] Petroleum, also known as crude oil, is a viscous, dark brown liquid. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum testing involves using testing equipment to detect the components in petroleum. Based on the test results, the quality of the petroleum can be determined. Typically, petroleum is extracted using a sampling device before testing.

[0003] For example, a portable sampling device for petroleum testing, with application number CN202323491692.8, includes a main body, a sampling mechanism, a sampler, an oil suction pipe and a solenoid valve, a threaded pipe, a connecting pipe, a sampling pipe, a controller and a control button. By installing the main body, this portable sampling device for petroleum testing can improve the leak-proof effect of the petroleum testing sampling device and avoid the occurrence of sample petroleum dripping and leakage.

[0004] When the above-mentioned sampling device extracts oil, it pulls the connecting block and the movable plug to slowly move backward by pulling the rod, and draws the oil into the sampling tank through the sampling tube. After the sampler completes the extraction of oil, since the sampler is cylindrical, it can only be placed flat. This setting method is prone to affecting the stability of the oil inside the sampler.

[0005] Therefore, we propose an oil testing and sampling device to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an oil testing and sampling device to solve the problem mentioned in the background art that, since the sampler is cylindrical, it can only be placed horizontally, which easily affects the stability of the oil placed inside the sampler.

The placement assembly is configured to assist the sampler in vertical placement, and the storage assembly is configured to integrate the sampling tube.

[0008] The placement component includes a placement mechanism and an adjustment mechanism with movable clips embedded on both sides of one end of the top surface of the placement mechanism. Telescopic rods are fixedly installed on both sides of the other end of the top surface of the placement mechanism.

[0009] Preferably, the feed assembly includes a threaded feed pipe and a solenoid valve fixedly installed on the outer periphery of one end of the threaded feed pipe.

[0010] Preferably, the sampler has rings fixedly installed at its upper and lower ends on its outer surface, and an inner groove is provided on one side of the outer wall of the rings. A magnetic cylinder is fixedly installed in the middle of the inner cavity of the inner groove.

[0011] Preferably, the placement mechanism includes a hollow round bottom block and an insertion cylinder fixedly installed on both sides of the upper end of the hollow round bottom block. The outer walls of the insertion cylinders are provided with multiple circular grooves at equal intervals in a linear fashion.

[0012] Preferably, the adjustment mechanism includes an insertion rod and a built-in groove formed on the lower end of one side of the outer wall of the insertion rod. An elastic element is fixedly installed in the inner cavity of the built-in groove, and a semi-circular retaining ball is fixedly installed at one end of the elastic element.

[0013] Preferably, the storage component includes a long block and a receiving circular block fixedly installed on the lower end of the outer wall of the long block. A hollow ring is fixedly installed on the middle part of the outer wall of the long block near the upper end, and magnetic inserts are fixedly installed at the upper and lower ends of the other side of the outer wall of the long block, respectively.

[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] Example 1: A petroleum testing and sampling device includes a sampler 1 and a piston rod 2 movably installed in the inner cavity of the sampler 1. An inlet assembly 3 is installed at the lower middle part of the sampler 1. A controller 4 is installed on one side of the outer wall of the sampler 1. A sampling tube 5 is threadedly connected to the lower end of the inlet assembly 3. A placement assembly 6 is fixedly installed at the lower end of the sampler 1. A storage assembly 7 is magnetically fixedly installed on one side of the outer wall of the sampler 1. The placement assembly 6 is configured to assist the sampler 1 in vertical placement. The storage assembly 7 is configured to integrate the sampling tube 5.

[0024] The placement component 6 includes a placement mechanism 61 and an adjustment mechanism 62 that is movable and embedded on both sides of one end of the top surface of the placement mechanism 61. Telescopic rods 63 are fixedly installed on both sides of the other end of the top surface of the placement mechanism 61. The upper ends of the adjustment mechanism 62 and the telescopic rods 63 are fixedly installed on the four corners of the lower end of the ring 11.

[0025] The feed assembly 3 includes a threaded feed pipe 31 and a solenoid valve 32 fixedly installed on the outer periphery of one end of the threaded feed pipe 31. The solenoid valve 32 is electrically connected to the controller 4. The solenoid valve 32 controls the opening and closing of the inner cavity of the threaded feed pipe 31, thereby sealing the threaded feed pipe 31 according to the usage requirements.

[0026] Solenoid valves are a current technology and are not limited here. They can be purchased as finished products from the market and installed, such as the ATM series solenoid valves.

[0027] The placement mechanism 61 includes a hollow round bottom block 611 and an insertion cylinder 612 fixedly installed on both sides of the upper end of the hollow round bottom block 611. Multiple circular grooves 613 are linearly and equally spaced on both sides of the outer wall of the insertion cylinder 612.

[0028] The adjustment mechanism 62 includes an insertion rod 621 and an internal groove 622 formed on the lower end of one side of the outer wall of the insertion rod 621. An elastic element 623 is fixedly installed in the inner cavity of the internal groove 622. A semi-circular retaining ball 624 is fixedly installed at one end of the elastic element 623. The insertion rod 621 is movably installed in the inner cavity of the insertion cylinder 612. The semi-circular retaining ball 624 is movably engaged in the inner cavity of the circular groove 613 under the elastic force of the elastic element 623.

[0029] In this embodiment: by pulling the piston rod 2 upwards within the sampler 1 cavity, the extracted oil enters the sampler 1 cavity through the sampling tube 5 and the threaded feed tube 31. Pressing the control button on the controller 4 controls the solenoid valve 32, closing it to prevent oil leakage from the threaded feed tube 31. After oil extraction, the sampling tube 5 is removed from the threaded feed tube 31, cleaned, and placed in the storage component 7 cavity. Because the sampler 1 has a hollow round bottom block 611 at its bottom, the oil is extracted through the hollow... The round bottom block 611 allows the sampling tube 5 to be placed vertically. At the same time, by adjusting the height of the insertion rod 621 in the inner cavity of the insertion tube 612, the distance between the insertion component 3 and the table can be adjusted. Specifically, by pressing the semi-circular retaining ball 624, it can be contracted under the elastic force of the elastic element 623. The semi-circular retaining ball 624 is then contracted. Moving the insertion rod 621 causes the semi-circular retaining ball 624 to slide, so that the semi-circular retaining ball 624 slides into the corresponding circular groove 613 and pops out and is fixed, thus fixing the length of the insertion rod 621.

[0030] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 A circular ring 11 is fixedly installed at the upper and lower ends of the outer surface of the sampler 1. An inner groove 12 is provided on one side of the outer wall of the circular ring 11. A circular magnetic cylinder 13 is fixedly installed in the middle of the inner cavity of the inner groove 12.

[0031] The storage component 7 includes an elongated block 71 and a receiving circular block 72 fixedly installed on the lower side of the outer wall of the elongated block 71. A hollow ring 73 is fixedly installed on the middle part of the outer wall of the elongated block 71 near the upper end. Magnetic inserts 74 are fixedly installed at the upper and lower ends of the other side of the outer wall of the elongated block 71. The magnetic inserts 74 are magnetically connected to the inner cavity of the circular magnetic cylinder 13. The bottom of the receiving circular block 72 is closed to facilitate the collection of the solution dripping after sampling by the sampling tube 5.

[0032] In this embodiment: by inserting the sampling tube 5 into the inner cavity of the hollow ring 73, the bottom of the sampling tube 5 is placed in the inner cavity of the round block 72, thus completing the placement of the sampling tube 5. This arrangement allows the sampling tube 5 and the sampler 1 to be placed as a whole, improving the overall integrity of the sampler 1. At the same time, when the sampler 1 is in use, the magnetic insert 74 can be moved by pulling the long block 71, so that the magnetic insert 74 can be separated from the round magnetic cylinder 13, and the storage component 7 can be disassembled, making it convenient to use.

[0033] Working principle: By pulling the piston rod 2 upwards within the sampler 1 cavity, the extracted oil enters the sampler 1 cavity through the sampling tube 5 and the threaded feed tube 31. Pressing the control button on the controller 4 controls the solenoid valve 32, which closes to prevent oil leakage from the threaded feed tube 31. After oil extraction, the sampling tube 5 is threaded out of the threaded feed tube 31. Because the sampler 1 has a hollow round bottom block 611 at the bottom, the sampling tube 5 can be placed vertically. Simultaneously, by adjusting... The height of the insertion rod 621 within the inner cavity of the insertion cylinder 612 allows for adjustment of the distance between the inlet component 3 and the tabletop. By inserting the sampling tube 5 into the inner cavity of the hollow ring 73, the bottom of the sampling tube 5 is placed within the inner cavity of the round block 72, thus completing the placement of the sampling tube 5. This arrangement allows the sampling tube 5 and the sampler 1 to be placed as a single unit, improving the overall usability of the sampler 1. Furthermore, when the sampler 1 is in use, the magnetic insert 74 can be moved by pulling the long block 71, causing the magnetic insert 74 to separate from the round magnetic cylinder 13, thereby allowing the storage component 7 to be disassembled.
