Description

Technical Field

[0001] This utility model relates to the field of oil sampling technology for storage tanks, and in particular to an oil sampling device for an internal floating roof storage tank. Background Technology

[0002] An internal floating roof tank is a storage tank in which an axle is installed on its internal axis, and a top cover made of a special lightweight material is placed on it according to its cross-sectional size. It can move up and down as the amount of objects inside increases or decreases, thus serving as a storage tank.

[0003] Due to the structural characteristics of internal floating roof tanks, the oil sampling process inside them is more complex than that of traditional tanks. Traditional oil sampling methods often struggle to accurately obtain oil samples at different heights within the tank, and the operation is cumbersome, easily leading to oil contamination and waste. Furthermore, existing sampling devices typically require manual entry into the tank, which not only increases operational risks but is also inefficient. Utility Model Content

The output end of the motor is provided with a worm gear. A rotating column is rotatably connected between the two first bearing seats. A take-up and untake-up roller and a worm wheel meshing with the worm gear are fixedly sleeved on the rotating column.

[0008] As a further improvement of this utility model, one end of the worm gear is provided with a second bearing seat that is fixedly connected to the tank body, and one end of the pull rope is connected to the take-up and release roller.

[0009] As a further improvement of this utility model, the top of the storage tank body is fixedly connected to two third bearing seats and a guide roller located between the two third bearing seats and rotatably connected thereto.

[0010] As a further improvement of this utility model, the inner surface of the top end of the sampling sleeve column is provided with an internal thread adapted to the sealing cap.

[0011] As a further improvement of this utility model, one end of the bottle cap is rotatably connected to the sampling bottle via a rotating shaft.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] This utility model provides the following: Figure 1-6 The oil sampling device for an internal floating roof storage tank shown includes a tank body 1, a floating roof 2 and a sampling sleeve 3 that passes through the floating roof 2 inside the tank body 1. The sampling sleeve 3 is a tubular column with several through holes 4 on its surface. The sampling sleeve 3 is vertically installed inside the tank body 1 and the floating roof 2 is slidably connected to the sampling sleeve 3. A driving mechanism is provided at the top of the tank body 1. The driving mechanism is connected to an oil sampling mechanism 6 that extends into the sampling sleeve 3 via a pull rope 5.

[0025] The oil sampling mechanism 6 includes an upper pull frame 601 fixedly connected to the pull rope 5. A sampling bottle 602 is fixedly connected to the bottom of the upper pull frame 601, and a bottle cap 603 is rotatably connected to the top of the sampling bottle 602. The upper pull frame 601 and the bottle cap 603 are connected by a telescopic rod 604. A filter screen 605 is provided at the top of the sampling bottle 602. One end of the bottle cap 603 is rotatably connected to the sampling bottle 602 through a pivot 606. A first connecting seat 607 is provided at the bottom of the upper pull frame 601, and a second connecting seat 608 is provided at the top of the bottle cap 603. Both ends of the telescopic rod 604 are hinged to the first connecting seat 607 and the second connecting seat 608 respectively by bolts 609. The bottle cap 603 can be opened by extending and retracting the movable end of the telescopic rod 604, thereby allowing oil samples to be taken from different depths.

[0026] like Figure 3 and Figure 4 As shown, the drive mechanism of this utility model includes a motor 7 and two first bearing seats 8 mounted on the top of the tank body 1. A worm gear 9 is provided at the output end of the motor 7. A rotating column 15 is rotatably connected between the two first bearing seats 8. A take-up / release roller 10 and a worm wheel 11 meshing with the worm gear 9 are fixedly sleeved on the rotating column 15. One end of the worm gear 9 is provided with a second bearing seat 12 fixedly connected to the tank body 1, and one end of the pull rope 5 is connected to the take-up / release roller 10. Two third bearing seats 13 and a guide roller 14 located between and rotatably connected to the top of the tank body 1 are fixedly connected. The rotation of the guide roller 14 ensures the smooth take-up and release of the pull rope 5.

[0027] like Figure 3 As shown, the inner surface of the top of the sampling sleeve column 3 in this utility model is provided with an internal thread adapted to the sealing cap, which can ensure the sealing of the storage tank body 1 when no sampling is performed, and prevent oil leakage or evaporation.

[0028] Working principle: In the specific implementation of this utility model, the control motor 7 is started, which drives the worm gear 9 to rotate, and the worm wheel 11 drives the rotating column 15 to rotate. The rotation of the rotating column 15 drives the take-up and release roller 10 to rotate, thereby realizing the take-up and release of the pull rope 5.

[0029] When sampling is required, the sealing cap is removed, and the take-up and release roller 10 is driven by the motor 7 to release the line. The oil sampling mechanism 6 is then placed inside the sampling sleeve column 3 by the pull rope 5 until the required oil sampling depth is reached. At this time, the movable end of the control telescopic rod 604 is shortened, causing the bottle cap 603 to open, and the oil can flow into the sampling bottle 602. After sampling is completed, the movable end of the control telescopic rod 604 is extended to close the bottle cap 603. Then, the motor 7 is reversed to cause the take-up and release roller 10 to take in the line, safely lifting the oil sampling mechanism 6 to the top of the storage tank body 1. This enables automatic sampling of oil at different depths inside the storage tank body 1, which improves sampling efficiency and ensures operational safety.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
