DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 7 As shown, a liquefied petroleum sampler comprises a mounting frame 1, a limiting sleeve 2 is fixedly mounted at the bottom of the mounting frame 1, a sampling bottle 3 is mounted in the limiting sleeve 2, a blocking cover 4 is mounted in the mouth of the sampling bottle 3, and a through hole 5 is formed through the upper surface of the blocking cover 4;

[0027] Connecting shafts 6 are rotatably mounted on both sides of the mounting frame 1, and a rotating frame 7 is fixedly mounted on one end of the two connecting shafts 6 away from each other. First connecting rings 701 are fixedly mounted on both sides of the upper surface of the rotating frame 7, and the first chains 702 are hung on the two first connecting rings 701. A mounting rod 8 is movably arranged at the bottom of the rotating frame 7, and a shielding cover 9 is fixedly mounted on the lower end of the mounting rod 8. A first spring 801 is sleeved on the side of the mounting rod 8 close to the shielding cover 9;

[0028] Mounting blocks 10 are provided on both sides of the top of the blocking cover 4, and slide bars 11 are fixedly installed on the lower surfaces of the two mounting blocks 10. A slide plate 12 is slidably provided on one side of the two slide bars 11, and a plurality of top rods 13 are fixedly installed on the upper surface of the slide plate 12;

[0029] Moving rods 1201 are fixedly installed on both sides of the upper surface of the slide plate 12 , and the upper ends of the two moving rods 1201 penetrate the blocking cover 4 and the shielding cover 9 .

[0030] The staff places the mounting frame 1 together with the sampling bottle 3 into the liquefied petroleum, and then controls the mounting rod 8 to move, so that the mounting rod 8 drives the shielding cover 9 to move upward, so that the shielding cover 9 no longer shields the blocking cover 4, so that the liquefied petroleum enters the sampling bottle 3 through the through hole 5 opened on the surface of the blocking cover 4, and the first spring 801 is compressed. After the sampling work is completed, the staff controls the mounting rod 8 to reset. Under the elastic force of the first spring 801, the shielding cover 9 shields the blocking cover 4 again to prevent the liquefied petroleum from continuing to flow in. Then the staff pulls the first chain 702, The sampling bottle 3 is removed from the liquefied petroleum to complete the sampling. When the opening of the through hole 5 is blocked by debris or debris is stuck inside it, the staff controls the movement of the moving rod 1201 to drive the slide plate 12 to rise along the slide rod 11, so that the push rod 13 moves into the through hole 5, so that it can push out the debris stuck in the through hole 5, and at the same time, it can also lift up the debris blocking the opening of the through hole 5, so as to prevent the debris from hindering the flow of liquefied petroleum gas and prevent the sampling process from becoming slow, thereby maintaining work efficiency. Finally, the staff pushes the moving rod 1201 to reset the slide plate 12 so that the sampling work can proceed normally.

[0031] In another embodiment of the present invention, a second spring 14 is sleeved on one side of each slide bar 11 close to the corresponding slide plate 12 .

[0032] Under the elastic force of the second spring 14 , when sampling is in progress, the slide plate 12 is not easy to move after being subjected to external force, so as to prevent the slide plate 12 from moving, causing the push rod 13 to block the through hole 5 and the oil from entering the sampling bottle 3 .

[0033] In another embodiment of the present invention, the upper surface of the slide plate 12 is configured as a curved surface.

[0034] By setting the upper surface of the slide plate 12 as a curved surface, the oil flowing into the sampling bottle 3 is not easily accumulated on the upper surface of the slide plate 12 under the guidance of the upper surface of the slide plate 12 .

[0035] In another embodiment of the present invention, an arc block 15 is fixedly mounted on the upper end of each push rod 13 .

[0036] By providing the arc block 15, after the push rod 13 lifts up the debris, the debris falls to the surroundings under the guidance of the arc surface of the arc block 15, avoiding the debris staying on the upper end of the push rod 13, causing the push rod 13 to continue to block the opening of the through hole 5 after it is reset.

[0037] In another embodiment of the utility model, a connecting sleeve 16 is fixedly installed on the upper surface of the blocking cover 4 and at the position of each through hole 5 , and an annular scraper 17 is fixedly installed in each connecting sleeve 16 .

[0038] By providing the annular scraper 17 , when the push rod 13 moves back, the annular scraper 17 can clean the rod body of the push rod 13 , thereby preventing impurities from being adsorbed on the surface of the push rod 13 and flowing into the sampling bottle 3 .

[0039] In another embodiment of the utility model, the upper ends of the two moving rods 1201 are fixedly installed with positioning plates 1203 by bolts 1202, and the second connecting rings 1204 are fixedly installed on one side of the upper surface of the two positioning plates 1203, and the second chains 1205 are hung on the ring bodies of the two second connecting rings 1204.

[0040] By setting up the second chain 1205, it is convenient for the staff to control the movement of the moving rod 1201. The staff can quickly disassemble the positioning plate 1203 by quickly disassembling the bolt 1202, so as to avoid the blocking cover 9 and the positioning plate 1203 being stuck when the staff moves the blocking cover 9.

[0041] In another embodiment of the present invention, the upper end of the installation rod 8 passes through the rotating frame 7 and is fixedly installed with a third connecting ring 18 , and a third chain 1801 is hung around the third connecting ring 18 .

[0042] By providing the third chain 1801 , it is convenient for the staff to control the movement of the installation rod 8 .

[0043] The working principle of this liquefied petroleum sampler:

[0044] When in use, the staff places the mounting frame 1 together with the sampling bottle 3 into the liquefied petroleum, and then controls the mounting rod 8 to move, so that the mounting rod 8 drives the shielding cover 9 to move up, so that the shielding cover 9 no longer shields the blocking cover 4, so that the liquefied petroleum enters the sampling bottle 3 through the through hole 5 opened on the surface of the blocking cover 4, and the first spring 801 is compressed. After the sampling work is completed, the staff controls the mounting rod 8 to reset, and under the elastic force of the first spring 801, the shielding cover 9 shields the blocking cover 4 again to prevent the liquefied petroleum from continuing to flow in, and then the staff pulls the first chain 70 2, so that the sampling bottle 3 is moved out of the liquefied petroleum, thereby completing the sampling. When the opening of the through hole 5 is blocked by debris or debris is stuck inside it, the staff controls the moving rod 1201 to move, so that it drives the slide plate 12 to rise along the slide rod 11, so that the push rod 13 moves into the through hole 5, so that it can push out the debris stuck in the through hole 5, and at the same time, it can also push up the debris blocked at the opening of the through hole 5, so as to avoid the debris hindering the flow of liquefied petroleum gas, prevent the sampling process from becoming slow, and maintain work efficiency. Finally, the staff pushes the moving rod 1201 to reset the slide plate 12 so that the sampling work can proceed normally.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
