Description

Technical Field

[0001] The utility model relates to the field of petroleum detection, in particular to a leakage-proof petroleum sample tank. Background Art

[0002] Petroleum is a natural organic compound, mainly composed of carbon, hydrogen and a small amount of sulfur, nitrogen, oxygen and other elements. It is the product of many organic substances on the earth formed by biological and geochemical reactions in the geological process. It is called "black viscous liquid". The petroleum sample tank is a container specially used for collecting, storing and transporting petroleum and its product samples.

[0003] During the oil testing process, the oil samples to be tested need to be transported and sealed. However, during the sealing process, they are mostly sealed directly through a cover plate and a single layer of sealant. This causes the sealing effect to deteriorate after long-term use of the device. At the same time, during transportation, because the oil extraction sites are mostly in mining areas, the road surface is extremely uneven, which will cause the device to shake and collide, causing damage to the outside of the device and exposing the oil.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-5, the utility model provides an embodiment: a leak-proof petroleum sample tank, including a sample tank body 1, the top two sides of the sample tank body 1 are fixedly connected with a fixed mounting frame 2, the interior of the fixed mounting frame 2 is slidably connected to a limited fixing plate 4, the interior of the fixed mounting frame 2 is rotatably connected with an adjusting threaded column 19, the outer side of the adjusting threaded column 19 is fixedly connected with an adjusting handle 3, the outer side of the adjusting threaded column 19 is respectively threadedly connected to the inner side of the limited fixing plate 4, a top sealing plate 5 is provided on the inner side of the sample tank body 1, and fitting notches 13 are provided on both sides of the top of the top sealing plate 5, a limiting sealing ring 14 is fixedly connected to the upper side of the inner wall of the sample tank body 1, and the limiting sealing ring 14 is connected to the bottom of the top sealing plate 5 through a positioning sealing component, and a stable support component is installed inside the sample tank body 1.

The bottom ends of the penetration columns 9 respectively penetrate the bottom of the outer sealing ring 11 and are fixedly connected with fitting glue columns 10. The middle part of the bottom end of the top covering plate 5 is fixedly connected with an inner sealing gasket 12, and a sealing notch 15 is provided inside the limiting sealing ring 14. A plurality of penetration positioning notches 16 are evenly provided inside the sealing notch 15. The outside of the fitting glue column 10 is respectively nested in the inside of the penetration positioning notch 16, the outside of the outer sealing ring 11 is nested in the inside of the sealing notch 15, and the outside of the inner sealing gasket 12 is nested in the inside of the limiting sealing ring 14. Both sides of the top of the top covering plate 5 are fixedly connected with a taking handle 6;

[0026] Specifically, the sample oil is placed inside the sample tank body 1, the top sealing plate 5 is placed on the inner side of the sample tank body 1, and the multiple fitting rubber columns 10 at the bottom end of the insertion column 9 are respectively inserted into the insertion positioning groove 16, and pressed downward, the outer sealing ring 11 is nested into the inside of the sealing groove 15, and the outer side of the inner sealing gasket 12 fits against the inner side of the limiting sealing ring 14, thereby performing a double seal. At this time, the adjusting handles 3 on both sides are rotated to rotate the adjusting thread column 19, and the outer thread of the adjusting thread column 19 contacts the inner thread of the limiting fixing plate 4, and the limiting fixing plate 4 is pushed inward, and the inclined surface of the limiting fixing plate 4 contacts the inside of the fitting groove 13. The inclined surfaces of the two contact each other, and the limiting fixing plate 4 generates downward pressure on the top sealing plate 5, thereby pressing and sealing the device, and the device performs positioning and limiting sealing, and multiple sealing, thereby further improving the sealing effect of the device and improving the storage effect.

[0028] Specifically, during the transportation of the device, when a collision occurs on the outside of the sample device, the external force acts on the outside of the soft tape 8, causing the soft tape 8 to deform, and the buffer groove 7 retracts due to the external force of the soft tape 8, reducing the force transmitted to the sample tank body 1, and the transmitted force is dispersed by the multiple support columns 18 inside the separation groove 17, thereby further ensuring the stability of the device, and multiple external restriction rings 20 restrict the outside of the sample tank body 1, improving the pressure resistance of the device.

At this time, rotate the adjustment handles 3 on both sides to rotate the adjustment thread column 19, and the external thread of the adjustment thread column 19 contacts the internal thread of the limiting fixing plate 4, and the limiting fixing plate 4 is moved inward. Pushed sideways, the inclined surface of the limiting fixing plate 4 contacts the inside of the fitting groove 13 to press and seal the device. During the transportation of the device, when the outside of the sample device collides, the external force acts on the outside of the soft tape 8, and the soft tape 8 is deformed. The buffer groove 7 retracts due to the external force of the soft tape 8, reducing the force transmitted to the sample tank body 1, and the transmitted force is dispersed by the multiple support columns 18 inside the separation groove 17, thereby further ensuring the stability of the device, and multiple external limiting rings 20 limit the outside of the sample tank body 1 to improve the pressure resistance of the device.
