Description

Technical Field

[0001] This utility model relates to the field of oil detection technology, specifically to an oil sample shaking device. Background Technology

[0002] In oil production, the cleanliness of lubricating oil, hydraulic oil, transformer oil, and other oils needs to be tested regularly using oil cleanliness testing instruments. The general testing procedure includes: extracting samples from the oil storage tank, placing them in sample bottles, and shaking the sample bottles before testing to resuspend any potentially settled solid particles and additives evenly in the oil, thus ensuring the accuracy of the test results.

[0003] However, existing sample mixing processes are usually carried out manually or with shaking equipment. However, the clamping position of existing shaking equipment for holding sample bottles is fixed and cannot be adjusted, making it difficult to hold sample bottles of different heights effectively. For sample bottles with shorter heights, manual shaking is the only option. Manual shaking is physically demanding, and the force and angle of manual shaking vary considerably, easily leading to uneven mixing. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an oil sample shaking device.

[0005] The technical solution of this utility model is as follows: A sample shaking device for oil testing includes a housing, a shaking plate inside the housing, the shaking plate being supported in the housing by symmetrically arranged support seats, both ends of the shaking plate being rotatably connected to the support seats via coaxial rotating shafts, and the rotating shaft on one side passing through the support seats and being connected to a drive motor outside the housing via a transmission assembly. The shaking plate includes a plate body and support plates symmetrically arranged on its left and right sides. One side of the plate body is provided with at least one arc-shaped limiting seat, and the arc-shaped limiting seat is provided with a first arc-shaped limiting groove. The two support plates are provided with an openable cover plate on the side away from the plate body. One side of the cover plate is provided with a second arc-shaped limiting groove corresponding to the first arc-shaped limiting groove. The first arc-shaped limiting groove and the second arc-shaped limiting groove can form a clamping position for clamping the sample bottle. The plate body has a top plate and a bottom plate on its upper and lower sides, respectively. The top plate has a limiting assembly, which includes a clamping member. The axis of the clamping member is parallel to or coincides with the axis of one of the first arc-shaped limiting grooves, and the length of the clamping member is adjustable. The bottom plate supports the bottom of the sample bottle placed on the first arc-shaped limiting groove, and the top plate limits the top of the sample bottle with the appropriate height. The top plate, bottom plate, and plate body are integrally formed.

[0006] To facilitate adjustment of the position of the clamping member, the limiting assembly also includes a T-shaped slider. The slider slides against the top plate and is connected to the top plate via a first connector. The upper end of the clamping member is connected to the lower end of the slider, making the position of the clamping member adjustable along the length of the top plate.

[0007] The specific structure of the clamping component is as follows: the clamping component includes a screw and a sleeve. The end of the screw is fixedly connected to the slider, and the inner wall of the sleeve is provided with an internal thread that is compatible with the screw.

[0008] The slider has the following structure: it includes an integrally formed T-shaped block and a mounting plate. The mounting plate is located outside the slide rail. The end of the screw is connected to the mounting plate. The length of the mounting plate is greater than the outer diameter of the screw. One end of the first connector can pass through the mounting plate and be pressed against the outer surface of the top plate.

[0009] To facilitate the clamping and limiting of the upper part of the sample bottle with a shorter height, so that the sample bottle with a shorter height can be shaken on the original shaking equipment, a clamping block is provided at the end of the sleeve away from the slider. The lower end face of the clamping block is a conical surface. Rotating the sleeve can adjust the position of the sleeve on the screw, so that the conical surface can approach and clamp the top cover of the sample bottle to limit it.

[0010] To facilitate the sliding of the sample vial cap and to protect the cap, a rubber anti-slip layer is provided on the conical surface.

[0011] Furthermore, two sets of arc-shaped limiting seats are arranged side by side, and two sets of second arc-shaped limiting grooves are arranged side by side. The two sets of second arc-shaped limiting grooves can correspond to the first arc-shaped limiting grooves respectively when the cover plate is fastened.

[0012] To prevent the top and bottom plates from interfering with the inner wall of the box when they rotate to their lowest point, the lowest points that the top and bottom plates can reach are both higher than the bottom surface of the box.

[0013] Furthermore, the drive motor is located on the upper part of the outer side of the housing, and a first gear is provided on one end of the rotating shaft. The drive motor is connected to the first gear through a belt drive assembly.

[0014] Furthermore, one end of the cover plate is rotatably connected to a support plate, and the other end is detachably connected to another support plate via a latch.

[0015] The beneficial effects of this utility model are as follows: By driving the motor and transmission components to drive the shaking plate to rotate synchronously, the oil sample in the sample bottle is automatically shaken. Compared with the manual shaking of the sample bottle, which causes greater shaking, it not only reduces the labor intensity of the staff, but also makes the oil sample shaken evenly, greatly improving work efficiency. The clamping position formed by the arc-shaped limiting seat and the first and second arc-shaped limiting grooves on the cover plate, together with the limiting components set on the top plate, forms a stable clamping of the sample bottle at the upper and lower points, ensuring the stability and safety of the sample bottle during high-speed rotation and shaking, and effectively preventing the risk of the sample bottle loosening, slipping or breaking. The length of the clamping component is adjusted by the threaded engagement of the screw and the sleeve. By rotating the sleeve, the conical surface at the lower end of the clamping block is driven to press the bottle cap, which can press and limit sample bottles of different heights.

A cover plate 7 is provided on the side of the two support plates 202 away from the plate body 201. One end of the cover plate 7 is rotatably connected to one support plate 202, and the other end is detachably connected to the other support plate 202 via a latch 8 (existing technology). The cover plate 7, like a door, can be opened and locked. The cover plate 7 has a certain thickness, and one side of the cover plate 7 is provided with a second arc-shaped limiting groove 701 corresponding to the first arc-shaped limiting groove 601. The first arc-shaped limiting groove 601 and the second arc-shaped limiting groove 701 can form a clamping position for holding the sample bottle.

[0019] In this embodiment, two sets of arc-shaped limiting seats 6 are arranged side by side, and two sets of second arc-shaped limiting grooves 701 are arranged side by side. The two sets of second arc-shaped limiting grooves 701 can correspond to the first arc-shaped limiting grooves 601 respectively when the cover plate 7 is fastened.

[0020] The plate body 201 has a top plate 203 and a bottom plate 204 on its upper and lower sides, respectively. The top plate 203 is provided with a limiting assembly, which includes a clamping member 9. The axis of the clamping member 9 is parallel to or coincides with the axis of one of the first arc-shaped limiting grooves 601, and the length of the clamping member 9 is adjustable. The clamping member 9 includes a screw 901 and a sleeve 902. The end of the screw 901 is fixedly connected to the slider 10, and the inner wall of the sleeve 902 is provided with an internal thread that matches the screw 901.

[0021] Multiple limiting components can be provided, and each limiting component can correspond to the first arc-shaped limiting groove 601, which can simultaneously limit multiple sample bottles with relatively low height.

[0022] The base plate 204 supports the bottom of the sample vial placed on the first arc-shaped limiting groove 601, and the top plate 203 limits the top of the sample vial with the appropriate height. The top plate 203, the base plate 204 and the plate body 201 are integrally formed.

[0023] See Figure 4 and Figure 6 As shown, in order to facilitate the adjustment of the position of the clamping member 9, the limiting assembly also includes a T-shaped slider 10. The slider 10 slides with the top plate 203 and is connected to the top plate 203 through the first connecting member 14. The upper end of the clamping member 9 is connected to the lower end of the slider 10, so that the position of the clamping member 9 along the length direction of the top plate 203 is adjustable.

[0024] The slider 10 includes an integrally formed T-shaped block 1001 and a mounting plate 1002. The mounting plate 1002 is located outside the slide rail 2031. The end of the screw 901 is connected to the mounting plate 1002. The length of the mounting plate 1002 is greater than the outer diameter of the screw 901. One end of the first connecting member 14 can pass through the mounting plate 1002 and press against the outer surface of the top plate 203 to fix the position of the slider 10.

[0025] See Figure 4 and Figure 6 As shown, to facilitate the clamping and limiting of the upper part of the sample bottle with a shorter height, allowing it to be shaken using the existing shaking equipment, a clamping block 11 is rotatably provided at the end of the sleeve 902 away from the slider 10. The lower end face of the clamping block 11 is a conical surface 1101. Rotating the sleeve 902 adjusts its position on the screw 901, allowing the conical surface 1101 to approach and limit the upper cap of the sample bottle. To facilitate the sliding of the sample bottle cap and protect it, a rubber anti-slip layer 1102 is provided on the conical surface 1101.

[0026] To prevent the top plate 203 and bottom plate 204 from interfering with the inner wall of the box 1 when the plate body 201 rotates to its lowest point, the lowest point that the top plate 203 and bottom plate 204 can reach is higher than the bottom surface of the box 1.

[0027] The drive motor 5 is located on the upper outer side of the housing 1. One end of the rotating shaft 4 is equipped with a first gear 12 coaxial with it. The output end of the drive motor 5 is also fixedly connected to a drive gear. The drive gear and the first gear 12 are connected by a transmission belt. The drive motor 5 is connected to the first gear 12 via a belt transmission assembly 13. It should be noted that the connection structure of the drive motor 5 driving the rotating shaft 4 to rotate via the belt transmission assembly 13 and the first gear 12 is existing technology and will not be described in detail here.

[0028] The cover plate 7 can be opened and closed. When the cover plate 7 is opened, the sample bottle containing the oil sample is placed on the corresponding first arc-shaped limiting groove 601. The bottom of the sample bottle is placed on the bottom plate 204. By fastening the cover plate 7, the second arc-shaped limiting groove 701 cooperates with the first arc-shaped limiting groove 601 to clamp the sample bottle. If the height of the sample bottle is not high enough to approach the top plate 203, the slider 10 with the clamping part 9 is inserted into the slide 2031 opened in the top plate 203. After adjusting the position, the sleeve 902 is rotated to drive the conical surface 1101 at the lower end of the clamping block 11 to press the bottle cap of the sample bottle. By tightening the first connecting part 14, the position of the slider 10 on the top plate 203 is fixed, and the drive motor 5 can be started to drive the rotating shaft 4 to rotate, thereby driving the shaking plate 2 and the sample bottle on it to rotate, realizing the shaking operation of the oil sample. The speed of the drive motor 5 is adjustable.
