Detailed Description
The present invention is directed to overcome the drawbacks of the prior art, and provides an oil sampler capable of sampling oil at multiple points simultaneously.
Example 1
As shown in FIGS. 1-2, an oil sampler capable of simultaneously sampling at multiple points comprises a sampling rope, a sampling box 1 and a winder.
Specifically speaking, sample box 1 includes the box body, and one side of box body is counter weight 2 district for can dismantle with sample rope I6 and be connected. The other side of the box body is hollow and is used for installing oil products, namely a sampling area.
The below in the sampling area of box body is equipped with sample connection 4, and 4 departments of sample connection set shrouding 5. Specifically, the closing plate 5 is opened, and oil can enter the box body from the sampling port 4. The closing plate 5 is closed to seal the sampling port 4.
Specifically, two mounting brackets extend downwards from the bottom of the box body sampling area. The closing plate 5 is connected with the mounting frame through a shaft to form a lever structure. One end of the closing plate 5 is positioned below the sampling port 4 and is closed; the other end of shrouding 5 surpasss the box body bottom for be connected with sample rope II7, be the link.
The blind end of shrouding 5 is equipped with the sealing washer that the round matches with the peripheral size of sample connection 4, is convenient for seal. Further, in this embodiment, 5 links of shrouding are equipped with counter weight 2, under 5 links of shrouding counter weight 2's the action of gravity for 5's of shrouding blind end has an ascending trend always, and 5 sealed effectual to sample connection 4 of shrouding.
Specifically speaking, the outer wall of the counter weight 2 area of the box body is fixed with a plurality of metal strips 3 which can be elastically bent, and the metal strips 3 are twisted into a ring shape and clamped on the sampling rope I6, so that the box body is fixed. The link light of shrouding 5 is equipped with ability elastic bending's metal strip 3, twists round annular card through metal strip 3 and on sample rope II7, realizes the fixed of connecting plate.
During the use, descend sample rope I6 and sample rope II7 simultaneously, when putting the assigned position, upwards pulling sample rope II7, under leverage, the link of shrouding 5 is upwards, and the blind end is downward, and sample connection 4 between produce inlet channel to realize the sample, put down sample rope II7, the link of shrouding 5 sinks the return in counter weight 2's effect, seals sample connection 4. At this time, the sampling rope II7 and the sampling rope II7 are lifted together to complete sampling. Because sample box 1 and sample rope I6 and sample rope II7 can dismantle the mode of being connected for can be equipped with a plurality of sample boxes 1 on the sample rope in proper order, according to oil tank height and sampling point height data, correspond a plurality of sample boxes 1 and install the sample rope correspond the length position can, thereby alright realize the multiple spot sampling simultaneously, solve the problem among the prior art.
Furthermore, in order to facilitate the simultaneous lowering of the sampling rope I6 and the sampling rope II7 and the independent lifting and lowering of the sampling rope II7, the invention is also provided with a winder.
The winder comprises two supporting plates 13, a central rotating shaft, a rotating handle 14, a handheld frame 15, a winding drum I10, a winding drum II11 and a locking nut 12.
Specifically, a central rotating shaft is rotatably provided between the lower portions of the two support plates 13. Two ends of the central rotating shaft are respectively connected with a rotating handle 14, the rotating handles 14 are arranged outside the two supporting plates 13, and the central rotating shaft is rotated through the rotating handles 14. A handheld frame 15 is arranged above the two supporting plates 13, so that the handheld frame is convenient to hold.
The central rotating shaft is divided into two sections, which are respectively defined as a rotating shaft I8 and a rotating shaft II 9. The diameter of the rotating shaft I8 is larger than that of the rotating shaft II 9. The rotating shaft I8 and the rotating shaft II9 are coaxial. And one end of the rotating shaft I8 and one end of the rotating shaft II9 are rotatably connected to form a central rotating shaft together.
The rotating shaft I8 and the rotating shaft II9 are rotatably connected, a groove is arranged at one end of the rotating shaft I8, and a limiting ring is arranged on the inner wall of the groove. One end of the rotating shaft II9 is located in the groove, one end of the rotating shaft II9 is provided with a limiting block, and the limiting block is located in the limiting groove, so that the rotating shaft I8 and the rotating shaft II9 can be rotatably connected.
The outer walls of the connecting ends of the rotating shaft I8 and the rotating shaft II9 are provided with threads. The locking nut 12 is arranged at the joint of the rotating shaft I8 and the rotating shaft II9, the inside of the locking nut 12 is variable in diameter, and two different inner diameter sections are arranged and matched with the sizes of the external threads of the rotating shaft I8 and the rotating shaft II9 respectively.
The winding drum I10 is fixedly arranged on the rotating shaft I8, and the sampling rope I6 is wound on the winding drum I10. The winding drum II11 is fixedly arranged on the rotating shaft II9, and the sampling rope II7 is wound on the winding drum II 11.
During the use, when rotatory lock nut 12 for lock nut 12 meshes with pivot I8 and pivot II9 simultaneously, pivot I8 and pivot II9 simultaneously rotate at this moment, can't relative rotation, and rotatory handle 14 just realizes transferring simultaneously of sample rope I6 and sample rope II7 at this moment.
When the lock nut 12 is rotated such that the lock nut 12 is engaged with only the rotation shaft II9, the rotation shaft I8 and the rotation shaft II9 can be relatively rotated. At this time, the rotating shaft II9 is correspondingly rotated to rotate the handle 14, so that the sampling rope II7 is independently lifted and lowered.
Example 2
The difference between this embodiment and embodiment 1 lies in that be equipped with the thermometer in sampling box 1, the thermometer is fixed in sampling box 1, and is equipped with the transparent part on the sampling box 1 outer wall for read the thermometer, thereby realize oil sampling and temperature measurement simultaneously.
The invention is well implemented in accordance with the above-described embodiments. It should be noted that, based on the above structural design, in order to solve the same technical problems, even if some insubstantial modifications or colorings are made on the present invention, the adopted technical solution is still the same as the present invention, and therefore, the technical solution should be within the protection scope of the present invention.
