Description

Technical Field

[0001] This utility model relates to the field of gasoline detection technology, specifically a sampling tube for gasoline detection. Background Technology

[0002] Gasoline is a fuel made by refining various gasoline components, such as straight-run gasoline, catalytic cracking gasoline, and catalytic reforming gasoline, and then blending them with high-octane components. It is mainly used as fuel for spark-ignition internal combustion engines in automobiles. After gasoline production and processing, it is necessary to use sampling devices to sample and test the gasoline to ensure the reliability of its quality.

[0003] Before gasoline testing, the methanol gasoline to be tested needs to be sampled. During sampling, the gasoline is usually drawn by inserting a hose connected to the machine's sampling tube into the tank. As the hose moves downward into the tank, the gasoline will slowly enter the hose. When the hose reaches the required sampling depth, the gasoline inside the hose will be collected along with the gasoline at the sampling point, which will lead to contamination of the gasoline at the sampling depth and result in inaccurate sampling. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a sampling tube for gasoline testing, which has the advantage of accurately sampling gasoline at different depths and avoids the problem of easy contamination of sampled gasoline.

[0005] To achieve the goal of accurately sampling gasoline at different depths, this utility model provides the following technical solution:

[0006] A sampling tube for gasoline testing includes a main board, a connecting bracket fixedly connected to the top of the main board, and a connecting plate slidably connected to the side wall of the connecting bracket. It also includes:

[0007] A top plate is fixedly connected to the side wall of the connecting plate, a sampling bucket is fixedly connected to the bottom of the top plate, a connecting pipe is fixedly connected to the bottom of the sampling bucket, a first telescopic cylinder is fixedly connected to the top of the top plate, a bottom plate is fixedly connected to the bottom of the first telescopic cylinder, a sealing plug is fixedly connected to the top of the bottom plate, and the sealing plug can extend into the inner cavity of the connecting pipe, a second telescopic cylinder is fixedly connected to the top of the top plate, and a piston is fixedly connected to the bottom of the second telescopic cylinder located in the inner cavity of the sampling bucket.

[0008] According to some embodiments, a servo motor is fixedly connected to the top of the connecting frame, a threaded column is fixedly connected to the output end of the servo motor, a sliding plate is threadedly connected to the side wall of the threaded column, the sliding plate is fixedly connected to the connecting plate, and the connecting plate is configured as a convex shape.

[0009] According to some embodiments, the bottom of the motherboard is rotatably connected to multiple sets of casters, and the casters are distributed at the four corners of the bottom of the motherboard.

[0010] Beneficial effects

[0011] This utility model provides a sampling tube for gasoline testing, which has the following advantages:

[0012] (1) The sampling tube for gasoline testing is used to place the sampling bucket into the gasoline depth through the connecting plate. At this time, the sealing plug is located in the inner cavity of the connecting tube, which can effectively prevent gasoline from sticking to the inner wall of the connecting tube during the process of the sampling bucket descending. This would cause the gasoline to enter the inner cavity of the sampling bucket and contaminate the sampled gasoline when the sampling bucket is sampled later. At the same time, after the sampling is completed, the sealing plug still seals the connecting tube.

[0013] (2) The sampling tube for gasoline testing drives the servo motor to rotate the threaded column. The threaded connection between the threaded column and the sliding plate causes the sliding plate to slide up and down. The connecting plate drives the sampling bucket to slide up and down through the top plate 2, and the sampling depth can be adjusted. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 A sampling tube for gasoline testing includes a main board 1, a connecting bracket 101 fixedly connected to the top of the main board 1, and a connecting plate 102 slidably connected to the side wall of the connecting bracket 101. It also includes:

[0020] A top plate 2 is fixedly connected to the side wall of the connecting plate 102. A sampling bucket 201 is fixedly connected to the bottom of the top plate 2. A connecting pipe 202 is fixedly connected to the bottom of the sampling bucket 201. A first telescopic cylinder 203 is fixedly connected to the top of the top plate 2. A bottom plate 204 is fixedly connected to the bottom end of the first telescopic cylinder 203. A sealing plug 205 is fixedly connected to the top of the bottom plate 204, and the sealing plug 205 can extend into the inner cavity of the connecting pipe 202.

[0021] A second telescopic cylinder 206 is fixedly connected to the top of the top plate 2, and a piston 207 is fixedly connected to the bottom end of the second telescopic cylinder 206 located in the inner cavity of the sampling barrel 201.

[0022] It should be noted that: when the sampling container 201 is lowered into the gasoline depth via the connecting plate 102, the sealing plug 205 is located inside the connecting pipe 202. This effectively prevents gasoline from adhering to the inner wall of the connecting pipe 202 during the descent of the sampling container 201, thus avoiding contamination of the sampled gasoline by the adhering gasoline entering the inner cavity of the sampling container 201 during subsequent sampling. After the sampling container 201 descends to the sampling depth, the first telescopic cylinder 203 is first activated. The first telescopic cylinder 203 drives the sealing plug 205 to slide to the connecting pipe 202 via the base plate 204. The piston 207 is then driven to slide upward by the second telescopic cylinder 206. The upward sliding of the piston 207 uses negative pressure to draw gasoline into the inner cavity of the sampling bucket 201 through the connecting pipe 202, thus completing the sampling. At the same time, the sampling amount can be controlled by controlling the upward sliding length of the piston 207. After the sampling is completed, the sealing plug 205 continues to seal the connecting pipe 202 to prevent gasoline from entering the inner cavity of the sampling bucket 201 during the upward movement of the sampling bucket 201. At the same time, the piston 207 can be controlled to slide downward to facilitate the removal of gasoline from the inner cavity of the sampling bucket 201.

[0023] Reference Figures 1-3 A servo motor 3 is fixedly connected to the top of the connecting frame 101, a threaded column 301 is fixedly connected to the output end of the servo motor 3, and a sliding plate is threadedly connected to the side wall of the threaded column 301.

[0024] The sliding plate is fixedly connected to the connecting plate 102, and the connecting plate 102 is convex.

[0025] The bottom of the motherboard 1 is connected to multiple sets of universal wheels 4, and the universal wheels 4 are distributed at the four corners of the bottom of the motherboard 1.

[0026] It should be noted that: the servo motor 3 drives the threaded column 301 to rotate. The threaded connection between the threaded column 301 and the sliding plate causes the sliding plate to drive the connecting plate 102 to slide up and down. The connecting plate 102 drives the sampling bucket 201 to slide up and down through the top plate 2, which can adjust the sampling depth. The device is movable through the universal wheel 4.

[0027] Operation method: Drive servo motor 3, servo motor 3 drives threaded column 301 to rotate. Utilize the threaded connection between threaded column 301 and sliding plate to make sliding plate drive connecting plate 102 to slide up and down. Connecting plate 102 drives sampling barrel 201 to slide up and down through top plate 2, which can adjust the sampling depth. The sampling barrel 201 is placed deep into the gasoline through connecting plate 102. At this time, sealing plug 205 is located in the inner cavity of connecting pipe 202, which can effectively prevent gasoline from sticking to the inner wall of connecting pipe 202 during the descent of sampling barrel 201, so that when sampling barrel 201 is sampled later, the sticky gasoline will enter the inner cavity of sampling barrel 201 and contaminate the sampled gasoline.

[0028] After the sampling barrel 201 descends to the sampling depth, the first telescopic cylinder 203 is driven first. The first telescopic cylinder 203 drives the sealing plug 205 to slide to the outside of the connecting pipe 202 through the base plate 204. Then, the piston 207 is driven to slide upward through the second telescopic cylinder 206. The upward sliding of the piston 207 uses negative pressure to draw gasoline into the inner cavity of the sampling barrel 201 through the connecting pipe 202, thus completing the sampling. At the same time, the sampling amount can be controlled by controlling the upward sliding length of the piston 207. After the sampling is completed, the sealing plug 205 continues to seal the connecting pipe 202 to prevent gasoline from entering the inner cavity of the sampling barrel 201 during the upward movement of the sampling barrel 201. At the same time, the piston 207 can be controlled to slide downward to facilitate the removal of gasoline from the inner cavity of the sampling barrel 201.
