Description

[0002] Since oil products are stored statically in oil tanks for a long time, many of their physical and chemical properties may change. In order to measure the performance and quality of the substances in the tanks, it is necessary to take samples of the oil products in the tanks for analysis and testing. Common petroleum products include gasoline, diesel and other liquid oils. The viscosity of liquid oil products is an important parameter for oil sample testing. Whether it is the production process of the oil products or the use of the products, sampling and testing of the viscosity of the oil products are required.

Since oil can precipitate or stratify during storage or transportation, direct testing can result in inaccurate viscosity data, hindering accurate assessment of oil performance. Therefore, the present invention proposes an oil viscosity testing device. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The following describes the preferred embodiments of the device of the present invention.

[0025] See also Figure 1-5As shown, the oil viscosity detection device includes a gantry 1, a fixed plate 2 is correspondingly provided at the inner top of the gantry 1, a connecting plate 3 is fixedly connected between the fixed plates 2, an electric telescopic rod 4 is provided at the center of the bottom end of the connecting plate 3, the output end of the electric telescopic rod 4 is fixedly connected to a mounting plate 5, and the bottom end of the mounting plate 5 is fixedly connected to a detector 6, a shaking mechanism 7 is provided at the inner bottom of the gantry 1, a placement cylinder 8 is provided at the top of the shaking mechanism 7, and a support column 9 is provided at the bottom end of the shaking mechanism 7.

[0026] In another embodiment provided by the present invention, Figure 3 and 4 As shown, the shaking mechanism 7 includes a mounting frame 701, a motor 702, a coupling 703, a support block 704, a worm 705, a worm wheel 706, a first rotating shaft 707, a first gear 708, a second gear 709, a second rotating shaft 710, a first sector tooth 711, a second sector tooth 712, a gasket 713, a fixing block 714, a slide plate 715 and a rack 716. The mounting frame 701 is arranged at the inner bottom of the gantry 1, and a motor 702 is provided on one side of the mounting frame 701. A coupling 703 is provided on the outside of the output end of the motor 702, and the output end of the motor 702 passes through the support block 704 and is rotatably connected to the worm 705. The other end of the worm 705 is provided with another support block 704, and the rear side of the worm 705 is meshed with a worm wheel 706. 06 is provided with a first rotating shaft 707 at the center hole, and the first rotating shaft 707 passes through the top of the mounting frame 701 and is connected to the first gear 708. A second rotating shaft 710 is provided next to the first rotating shaft 707, and the second rotating shaft 710 passes through the top of the mounting frame 701 and is connected to the second gear 709. The first gear 708 and the second gear 709 are meshed with each other. The top of the first rotating shaft 707 and the second rotating shaft 710, and above the first gear 708 and the second gear 709, are respectively rotatably connected with the first sector tooth 711 and the second sector tooth 712. A fixed block 714 is correspondingly provided laterally on the rear side of the top of the mounting frame 701. A slide plate 715 is provided for sliding between the two fixed blocks 714, and a rack 716 is provided at the bottom front side of the slide plate 715.

[0027] The first sector teeth 711 and the second sector teeth 712 are arranged in opposite directions, and the rack 716 is engaged with the first sector teeth 711 and the second sector teeth 712 , and the rack 716 is driven to reciprocate through the first sector teeth 711 and the second sector teeth 712 .

[0028] The horizontal height of the rack 716 is higher than the horizontal heights of the first gear 708 and the second gear 709 , which does not affect the driving of the rack 716 by the first sector teeth 711 and the second sector teeth 712 .

[0029] Specifically, start the motor 702. The motor 702 transmits power to the worm 705 through the coupling 703. When the worm 705 rotates, the worm gear 706 meshing with it begins to rotate. A first rotating shaft 707 is provided at the center hole of the worm gear 706. Therefore, the rotation of the worm gear 706 drives the first rotating shaft 707 to rotate. When the first rotating shaft 707 rotates, the first gear 708 on the first rotating shaft 707 and the second gear 709 on the second rotating shaft 710 mesh with each other, and the second rotating shaft 710 also rotates synchronously. When the two gears rotate synchronously, the first sector teeth 711 and the second sector teeth 712 drive the rack 716 to reciprocate between the fixed blocks 714. As the rack 716 reciprocates, the slide 715 also reciprocates, thereby driving the oil container to shake evenly, ensuring that the oil reaches a uniform state before testing.

[0030] In another embodiment provided by the present invention, Figure 5 As shown, a placement cavity 801 is opened between the inner side and the outer side of the placement tube 8, and a heating wire 802 is laid around the placement cavity 801.

[0031] The placement tube 8 and the detector 6 are located in the same vertical plane.

[0032] Specifically, the temperature inside the cylinder 8 can be precisely controlled by the heating wire 802 to ensure that the oil reaches a preset, stable temperature before testing. This not only improves the accuracy of testing, but also ensures the reliability of oil performance evaluation.

[0033] During use, the sample tube containing the oil is placed in the placement tube 8, and the heating wire 802 is started to heat the oil in the placement tube 8. During the heating process, the heat generated by the heating wire 802 is transferred to the oil through the wall of the placement cavity 801, causing it to gradually heat up to a preset detection temperature. At the same time, or when the oil temperature approaches a preset value, the shaking mechanism 7 is started to evenly shake the oil in the sample tube to ensure that the oil temperature is evenly distributed without precipitation or stratification. When the oil reaches the preset temperature and is uniform, the electric telescopic rod 4 lowers the detector 6 to a position corresponding to the placement tube 8, and the detector 6 starts working to detect the viscosity of the oil.
